A guess for 795. You put it into something, turn the screw to push the
lugs out, and then pull it to remove the thing you've pushed it into
from some other thing into which it fits snuggly.

Hmm, having written that it's not much of a guess.

794: For recording old audio cylinders? Early dictaphone?

796: RJ11 phone jack (male)

According to R.H. :

As usual -- posting from rec.crafts.metalworking.

793) Perhaps for cutting or scoring a groove in the edge of
something wooden?

A closer look at both ends of the blade clamped in it might help
somewhat.

794) A *very* old office dictation machine. It looks as though it
uses something like Edison cylinders.

795) This looks as though its function is to slide in a square tubing,
and then to be locked at a certain extension. Perhaps it is to
be an extendible leg on some furniture?

796) A "modular phone plug" model RJ-11. (RJ-13 is the six-conductor
one, and RJ-45 is the eight conductor one, which is used for
twisted pair ethernet among other things.

A somewhat narrower version is used for handset cords for phones
of a certain age.

797) It looks as though it is intended to pull chain links together,
perhaps to allow a "repair" link to be installed. And, at a
guess, the two notches in the faces of the flat jaws are to
close an opened link once it is in place.

798) The end of the pocket knife looks as though it is is intended
to smooth a surface by rocking back and forth in contact with
it.

Perhaps for burnishing paper which has been erased by scraping
off the ink? In that case, the blades might be to cut a new
point in a quill pen?

Now to see what others have said.

When can you safely go back to the Roman numerals? They make
this thread easier to find -- but obviously you don't want them
classified as porn spam, which I believe was the reason to abandon
temporarily the Roman numerals in the first place.

Actually, the "RJ" numbers are wiring patterns for specific
applications, not the connectors. They are named *p*c, for the number
of postions and the number of conductors.

That is the 4P4C wired as a four conductor handset cord. The one in

Correct answers so far:


793. Stanley clapboard gauge

794. Ediphone dictation machine

795. Not sure about this tool yet

796. Telephone plug

797. One of the functions of this multi-tool is a can opener, but I don't
know if the wrench is for a specific purpose. I haven't had time to search
the patent date.

797. Also don't know about the pocket knife.


I'm going to be away from my computer until sometime on Saturday, I'll post

--- Black Holes are where God is dividing by zero ---

794: is a "record" recorder. It was used to create I believe 78 rpm
albums. These were quite the rage.

796: in its current configuration thats a "line cord" for a RJ-14 or
RJ-25 jack. Better known as a telephone cord. Because it does NOT have
only 2 wires it would not typically be used with an RJ-11 jack, though
it could be. IF you only were interested in the "1st line" The wiring
is inside to out. Meaning the inner two wires would be line 1 (
Red/green ) and the outer two would be "line 2" (yellow/black.).
ORINGALLY yellow was a power line for the lighting circuitry on the
"princess" style phones with the black providing the ground as the
"dialtone" on a landline phone is -48vdc.

798: has all the "looks" of a barlow knife. The rounded hammer head
suggests a shaping usage.

Hmm ... the phone company (the originator of these, IIRC) uses
RJ-48 for both of the wiring patterns on the identical connector for a

The only difference is the suffix which indicates the differing wiring

I don't believe so. The one shown has the fatter side walls,
producing a connector the same width as the 6-pin version. You can see
the grooves which would accept the extra blades (and in this case,
simply prevent damage to the wire pins in a 6-conductor jack).

The 4-pin used in the handsets (at least in the old ITT one in
my hand at the moment) is narrower, and does not have the unused grooves
outside the four in actual use.

795: Looks to me like this is a set of quoins used to tighten moveable
printing type in a chase to keep the type from falling out while in the
printing press.

Hi, all

I've been lurking here for a bit, but haven't posted before. I don't
know what 795 is, but I'm pretty sure they aren't printers quoins. I
can't pretend to be a world-class expert on quoins, but I did spend
three years working with old printing equipment at a historic
restoration on Staten Island, and I've never seen this style of quoin
before. Furthermore, they don't look to be well adapted for the
purpose. First of all, quoins have to generate a _lot_ of force. The
form is almost an inch thick of solid lead and is held in place
entirely by the friction resulting from the force that the quoins exert
at the edges. All the quoins I've ever seen are wedges with vertex
angles on the order of ten degrees. This device seems to have vertex
angles more like eighty degrees, meaning it's designed to quickly take
up a relatively large amount of slack, but generates relatively little
force. Second, this device appears to be designed to exert force
between two surfaces that are significantly out of parallel. That
wouldn't be an issue in a printing form. Third, with the actuating
screw on the end like that, the device would be rather awkward to
tighten in a chase. The quoins I've used have either been actuated by
a key inserted from the top (the side, in the photo), or are driven in
place with a mallet and "shooting stick."

I'm not 100% sure, but that isn't how I'd make a set of quoins if I
were designing them.

Nutcracker
Wrench
Pliers
Tack puller
Pruner
Wire cutter
Can opener

Link:

http://www.pat2pdf.org/patents/pat286458.pdf

I had to look it up, so I didn't think it was all that fair
to post an answer right away.



Thanks! And also thanks for discovering the patent numbers for both of the
quoins (number 795 and 763). I've showed number 795 to a lot of people and
thought I was never going to find out what it was.

I updated the answer page for number 763 with a link to the patent:

I'll see if I can put something together about searching via
classes sometime soon (per the other thread/question). It
takes some work and learning and isn't for the impatient or
faint-of-heart


Sounds good, whenever you have time to post some tips, I'd appreciate it.

I got a new Jameco catalog in the mail today with the amp modular

connectors, but the picture stinks. They have the rather rare 10P10C
connector as well. If you look at the top right section of the page you
will see that there are two widths of 4P4C modular jacks available.
Since the handset doesn't connect to the telco, it doesn't need an
Registered Jack number. I can scan the wider plug for you, but not
tonight. I do my graphics work on another computer that's in the house,
and I'm working in one of my shops tonight.

Just checking! ;-) Most people think all "sub D" shells are 'DB"

Also -- *any* size of the "Miniature Blue Ribbon" connectors by
Amphenol is now called "Centronics", simply because Centronics (the
printer manufacturer) selected that connector for the parallel interface
which they used. I find myself greatly frustrated by the use of the
term for the 50-pin connectors used for SCSI on many systems. (For the
50-pin, I prefer the locking connector made mostly by AMP and used on
the Suns before they went to fast wide SCSI with 68-pin connectors
replacing the 50-pin ones.

The
originals Sub-D connectors were made by Cinch.

Though Cannon was another common manufacturer of those. Each
had different designs of backshells -- some much worse than others.

Also, the SVGA monitor
plug is a "HDE-15" sub D connector. I have about 500 different types of
connectors on hand for repairs, including some that haven't been made in
over 60 years. (A four pin tube socket for the very early "Breadboard"

The ones with two pins fatter than the other two, so filament
fed through two, and the other two were grid and plate -- and the
filament served as the cathode as well? Or the ones where grid and
plate were separate connections through the walls of the tube?

plugs on page 115. they also have their ValuePro line with the 4P4C
connectors, but the picture stinks.

So it does.

They have the rather rare 10P10C
connector as well.

I would like to get a crimper for those. I have an sBus card
for older Sun workstations which provides four serial ports through such
connectors -- though I really don't need the outer two pins -- they are
for carrying the signals for synchronous serial and asynchronous is all
that I need.

If you look at the top right section of the page you
will see that there are two widths of 4P4C modular jacks available.
Since the handset doesn't connect to the telco, it doesn't need an
Registered Jack number. I can scan the wider plug for you, but not
tonight. I do my graphics work on another computer that's in the house,
and I'm working in one of my shops tonight.

Actually -- the top of that page shows two four-pin connectors,
but only one is a 4P4C. The other is marked as 6P4C. The 4P4C is
labeled with the descriptive word "handset", while the 6P4C is one of
two marked "RJ11". All three have WE numbers -- an Western Electric is
good enough to be Phone Company -- at least back in the old days. :-)

Hmm ... I'll have to look at what DD form I got when I retired

How hard would it be for you to machine the outer edges from one of
the 8P8C dies to make it wide enough? If you don't need the wires, you
don't have to worry about crimping those positions. Personally, I would
make my own dies for my 1 ton arbor press. I have severe Carpal Tunnel
Syndrome, so some hand tools are out of the question most days. I used
custom dies with a 1/2 ton arbor press for crimping ribbon cable into
IDC sub-D connectors, and IC headers at Microdyne. We had 25 people who
made cables for production, but I preferred to make my own for test
fixtures, rather than spend a half hour explaining what i needed. A
quick and dirty guide for the pin side of the IC header connectors can
me made from a stack of three or four layers of phenolic or glass epoxy
perf board drilled in a .1" * .1" grid instead of drilling a metal
plate. A couple screws from the bottom of a scrap piece of 1'8"
aluminum plate allows you to replace the perf board when it wears out.
It has the advantage of fitting every version made with .1" spacing, and
will last for 500 to 1000 crimps if you don't abuse it.

#798: Veneer/inlay knife?
That end could be used for tamping a pipe, but tampers usually are
round. I'd
venture it's a veneering knife; one uses a veneer hammer to press glued
veneers into
place, and the curved shape of that end is about right for a veneer
pressure job.

You'd have to clean glue from the knife, though...

Sounds like a good possibility, I'll see what I can find on that.

By the fact that my newsreader's threading does not have it

Yep! I wonder where some of these things come from.

a single screw to hold it together. I think I saw a couple hundred DB 25
hoods the other day at the local surplus metal dealer. I'll take a
notebook the next time to write down the AMP number.

The AMP ones also have a second screw (a long slotted setscrew),
in a square nut which drives the tapered Delrin block which serves as
the cable clamp. IIRC, some of the earlier ones had three screws,
instead of just one.


The ones with two pins fatter than the other two, so filament
fed through two, and the other two were grid and plate -- and the
filament served as the cathode as well? Or the ones where grid and
plate were separate connections through the walls of the tube?


Yes, it is black bakelite with a pair of "F"s , a "G" and a "P"
molded in. It is made to be screwed to a board, and top wired.

Interesting. *Those* I don't have -- though I have some octal
ones which were used mostly for relay sockets in industrial controllers.

Do you have any "loctal" sockets around still?

I got a new Jameco catalog in the mail today with the amp modular
plugs on page 115. they also have their ValuePro line with the 4P4C
connectors, but the picture stinks.

So it does.

They have the rather rare 10P10C connector as well.

for older Sun workstations which provides four serial ports through such
connectors -- though I really don't need the outer two pins -- they are
for carrying the signals for synchronous serial and asynchronous is all
that I need.


How hard would it be for you to machine the outer edges from one of
the 8P8C dies to make it wide enough?

IIRC, the overall width of the connector is the same. They have
simply taken some of the thick walls of the 8-pin version and added
another pair of slots for the blades -- and of course the internal guide
grooves for the wires under the blades.

They don't bother documenting the width for either those or the
8-pin connectors in that catalog page.

Certainly if the connector is wider, I won't have room to widen
the dies for my AMP crimper for the modular plugs -- and AMP/Tycho does
not sell dies for that crimper. But perhaps I could work with one of
the cheaper "pliers" crimpers for that purpose.

If you don't need the wires, you
don't have to worry about crimping those positions. Personally, I would
make my own dies for my 1 ton arbor press. I have severe Carpal Tunnel
Syndrome, so some hand tools are out of the question most days.

Then you would probably like my crimpers for 8 ga through 4/0
terminal lugs. It is a hydraulic head, with the choice of a hand-pump,
a foot pump (which I don't have), or an electrically-cycled pump. I'm
set for all of them except 4/0. I don't have those dies. There are two
heads -- one for 8 Ga through 2 Ga, and the other for 0 (1/0) through
4/0. I got the electrical pump first -- as part of a surplus sale when
I was after something else -- but once I saw it I realized what it was
and kept it.

For the smaller range (8 Ga through 2 Ga) there are other
self-contained hand-held and hand-pumped hydraulic crimpers -- but for
the 1/0 through 4/0, the head is always separate. I first *used* one of
those when I worked for Melpar back in the mid 1960s, and they had the
foot-pumped version at that time. This is why I recognized the
electrical pump when I got it. :-0

I used
custom dies with a 1/2 ton arbor press for crimping ribbon cable into
IDC sub-D connectors, and IC headers at Microdyne. We had 25 people who
made cables for production, but I preferred to make my own for test
fixtures, rather than spend a half hour explaining what i needed. A

It has the advantage of fitting every version made with .1" spacing, and
will last for 500 to 1000 crimps if you don't abuse it.

Somewhere I still have a crimper made from a smaller arbor press
than the 1/2 ton one -- dies and guides which were semi-affordable. I
now have a really nice press by T&B Ansley which came from a hamfest.
Thank goodness I had a folding wheeled cart to carry it back to the car. :-)

will see that there are two widths of 4P4C modular jacks available.

Yes -- but we were talking about the plugs, not the jacks.

In the plugs section, only the narrower one is called a "4P4C".
The wider one is called a "6P4C", and is given a WE part number of
"623", while the "4P4C" is given a WE part number of "616". Of course,
the "6P6C" is also given the WE part number of "623".

it seems that there is a bit of confusion between the
terminology of the plugs and the jacks. Measuring the width of my
example of a "4P4C", I come out with 0.298" (Probably 0.300" was the
target dimension.)

Note also that there are some other specialized ones which I
don't see here. There is a 6P6C which has the locking clip offset to
one side which is used as a serial port on DEC VT-320 terminals -- and I
think the VT-220 as well.

Amp makes a set of dies for my crimper to handle those too.

Hmm ... I'll have to look at what DD form I got when I retired
