As always, I haven't looked at anybody else's answers, and I'm not as
knolwedgeable as other people about these items. So take my wild-assed
guesses for what they are.
1295 looks like it's used to grind something, and then distribute it
evenly. What that something is, however, I don't know.
1296 Five inches seems to small for a vacuum pump for canning, although
the glass jars below make it look as though the device is used in
canning in some way. Eithe that, or it's part of a Leyden jar.
1297 Multiple socket set?
1298 used to start holes for some nails, and pull others out? If it
weren't for the nail-pulling part, I might guess it's for creating
evenly spaced holes on a belt.
1299 looks like a housing for a lighthouse light, except that I'd think
37 inches is a bit small for that.
1300 looks like it would be used with a switch in telegraphy

I want to say "farm battery" for the battery, but I know that's
something I saw here anyway.

Based on the number of people who said it was a relay, I had a feeling that
this might have been tagged wrong. I just changed my answer to "telegraph
relay".

I don't own this device and I took the photos several weeks ago, so I can't
check the silver part. If I remember correctly it was completely hollow and
open on both ends, so if it was a tear-gas cartridge it was already used.

As mentioned in a previous post, I just fixed this answer, good job on
finding the photos of a similar device, I did some searching and didn't have
any luck. Thanks for the information on the relay, I like to include pieces
of old technology on the web site but I'm not an expert in that field.

I just modified the answer page to include the tear gas description, I was
wondering what that piece was for, the box didn't mention tear gas so I'm
thinking the owner just happened to store it in the same container since
they are similar.

Jeff,
Before looking back at the blogspot page, I was thinking that 1297 was the
number of the first item this week, and imagining the effect it would have
on either end of an animal!

DoN is absolutely correct.
I was careless, hasty, and lazy. I didn't read his full message. I read
down to the second divider bar and charged off with an unnecessary message.
If I had been courteous enough to read a little further, I'd have seen his
later links and would have kept my big yap shut.
I apologize to the group, DoN, and RH for my bad message and impolite
behavior.
Thanks to RH, DoN, and everyone else.

Some of these I actually know this week
1295. A capper of some sort? Caps go in the funnel and are screwed on.
1296. A wet cell battery. This one should produce about 6 volts. For use
with railroad or telephone equipment?
1297. These are normally tear gs pens. Rob has shown similar before. The
all-metal construction of the cartridge may mean it's a flare gun instead.
1298. Upholstery or carpet-laying tool.
1299. Fresnel lens for a beacon/bouy or lighthouse
1300. Could either be a relay or a telegraph "clicker"/sounder

1295 -- It looks like a brace for boring, tapping, or reaming. The
funnel suggests it was for working with metal. It looks as if it used
large bits that had to be changed frequently.
I'd say this was for use where it might be inconvenient to carry and put
down a can of cutting oil. You'd fill the funnel through the tapped
hole and put in the plug. Then when you needed a little oil you'd pull
the trigger.

Hey, I'm actually pretty sure about a few of these--a rarity indeed.
1295 - Separator for e.g. gold panning? Combination bit brace, battery
terminal cleaner, and seed spreader? Very peculiar....
1296 - Smallish six-cell wet battery, presumably putting out a voltage
of (nominally) 12V, probably for laboratory or radio work.
(It could possibly also be an electrolytic rectifier, but I would not
expect to see six cells wired in series in that case. If you had
voltages that high, you'd presumably use a high-voltage rectifier tube
(or mercury rectifier) in that era. I would expect instead either three
cells, one with three electrodes, or else four cells wired in a bridge.)
1297 - Ummm...these would seem to give a measured mechanical impulse,
but to what end? I've no idea.
1298 - Removable handle to manipulate e.g. large hay bales?
1299 - Fresnel Lens from a lighthouse. From it's size, I'd guess it's
one used in relatively small light in a bay or inland waterway, rather
than on the ocean coast proper.
1300 - This is one of two very closely related devices--either a buzzer
or an interrupter used to generate a pulsed signal for an induction
coil. I would tend to suspect the latter application. The frequency of
operation is varied by twiddling the various adjustment screws (the
limits of the swinging arm's travel and its spring tension).
Now to see other guesses.

1300 Relay or sounder? I'm not fool enough to argue with the strong
assertion that this is a relay and not a sounder... but I've a question and
a quibble...
Relays are usually 4-terminal (possibly 3-terminal) devices, having input
and output. Sounders are usually 2-terminal having audio output. I agree
that DoN's reference includes a repeating sounder/relay, but it has at least
one extra terminal. The thing (1300) doesn't seem to have more than 2
terminals, with the other screws seeming to be adjustments (front-stop,
back-stop, pivot-bearing and tension). The question is, where are the extra
terminals needed to make a relay?
The quibble is that, in DoN's reference, there are a variety of sounder
impedances listed, going up to 400 ohms, and including the value given for
the thing.

I am pretty sure that #1300 , although similar to, is not a "sounder". A
sounder has a much heavier armature and a substantial stop so that it makes
a quite loud sound when operating. As several others have said, this is
actually a relay or repeater, used with a local battery for operating the
sounder and retransmitting the signal further along the line. These were
designed to be light and sensitive so they would operate reliably on signals
too weak to directly operate the sounder. An early form of amplifier.

O.K. Posting from rec.crafts.metalworking as always.
1295) *Strange* beastie. It looks like a marriage between a wrench
for removing plugs from a steel drum (barrel), and a funnel with
a flip-top lid.
And -- there seems to be a cap over the spout of the funnel,
suggesting that it is for carrying samples to the drum,
unscrewing the plug, releasing the funnel contents into the
drum, an then screwing the plug back in place.
I have no idea where this would be used, but that is what its
function seems to be to me.
1296) This looks like a top plate from an old lead-acid storage
battery and glass containers to separate the individual cells
from each other. But there does not seem to be enough stocking
down into the glass containers to form the plates of the cells,
so I would have to say that those are probably lost -- perhaps
mostly etched away by the battery action over the years.
1297) If it were just the first photo, I would have said that it
could either be a pen-gun to fire .22 LR or somewhat larger
cartridges, or a tear-gas pen gun.
The second photo says that it is the tear-gas version. I once
had one which fired .38 special tear gas cartridges.
*And* -- the red cartridge may be a flare gun. The smaller
tapered one is a style which I had as tear gas, though the pen
gun part was a bit different.
1298) A streamlined handle of some sort. I've got two guesses, and
I'll put the one I consider the more likely first:
A handle which is attached to a limousine to allow security
personnel to hold on (and stand on foot pads) on the exterior of
the vehicle when used in parades and the like.
Or
A handle to attach to a curling stone. (I've never seen a
curling stone in person, so I could be very wrong here.)
1299) The lens and light source from a lighthouse -- in a museum
somewhere. This one appears to be gas fired.
1300) Telegraph repeater. Telegraph lines had a certain resistance
per foot, and after enough miles there was not enough current
available to operate the sounder at the receiving end. This
would be placed at some intermediate spot, the sensitivity
adjusted so it would reliably move with the key at the sending
end (using the knurled knob which winds up a string connected to
the end of the spring), and the contacts would switch the output
of a new battery to send the signal on to the next relay or to
the final receiving station where a sounder would be located.
If the signal was weak enough, there would probably be a relay
there too to feed good current to the sounder.
From the looks of the board, it was designed to be screwed to
the wall -- and there might be more than one of them receiving
signals from several distant sources.
Now to see what others have guessed.
Enjoy,
DoN.

O.K. I have to take issue with two of these.
1297) While I'll agree that most of this is a flare gun, the smaller
silver-colored screw-in part is a tear-gas cartridge. I'll bet
that if you look at the other end, it will have a light green
wax or plastic seal poured into it.
The red one I will agree is a flare.
1300) This is *not* a telegraph sounder. Those have much more mass,
and are designed to make noise which is easy to hear as they
cycle.
This is a *relay* (or repeater) -- It is designed to be quiet,
and to make electrical contact as it cycles, not to make noise
with those small contact points and the low mass moving part.
Note how the point when it is relaxed is an insulating material
(white -- ceramic perhaps?), and the other ine is metal, to make
contact between the moving arm and the frame.
It may have been *tagged* "telegraph sounder", but it is not
one. Your link <http://mysite.du.edu/~jcalvert/tel/sounder.htm>
points to a drawing of a real sounder -- note the massive bar
which moves and makes a loud and clear "clack" as it hits the
stops. (Note also that the coils are a lot lower resistance.
That one is marked "4 Ohms", not the 250 Ohms from the one which
you have.
There are a lot of links were -- but go to the last three (at
the bottom of this article), which are photos of the same model of
relay -- properly identified.
Visit <http://artifaxbooks.com/fslandline.htm> to see a couple of
relays after a lot of sounders. The two relays are:
#0406BTP Rare Bunnell Ghegan relay
and
#RW525BLY Western Electric no. 22A relay
or eBay item: 300222480525
and, from another site:
http://www.njarc.org/articles/The%20Telegraph%20Office%201-2.html
(with a photo at the site)
======================================================================
Telegraph lines were copper or iron wire. Hence after a certain
distance, the resistance of the wire attenuated the current in
the line, rendering the sounder insensitive. To extend the
useful range of the telegraph, relays were used. The relay is
basically an electromagnet as is the sounder.However, the
solenoids of the electromagnet usually have more turns of wire
and therefore are quite sensitive. The armature, instead of
making a clicking noise, was one half of a set of contacts.
When the operator on the sending end pressed his key, the
armature completed a new circuit. The relay is the mid 19th
century electromechanical version of the 20th century
amplifier. Relays had the same life cycle as keys and sounders.
However, they are not as plentiful as keys and sounders because
not every installation required one. (The relay was the genius
of Joseph Henry, two decades before Morse put it to practical
use.)
======================================================================
Now -- there *should* be another pair of terminals to connect to
the coils -- but the angle of view keeps us from seeing this for sure.
A relay would have four terminals total, a sounder only two.
Aha! Here it is:

http://home-and-garden.webshots.com/photo/2230641500037774971ZslIXZ
The last of those photos shows the model plate -- which matches.
And -- the photos show the extra two terminals which I predicted.
Enjoy,
DoN.

If you had looked at the final images in my article (which I
pointed to at the beginning once I found them), you would have seen
photos of another one (same model number on the maker's plate) which
included angles which showed that there were two more terminals hiding
behind the relay coils as photographed in the puzzle set. I'll leave
those URLs quoted at the end, after trimming out all of the others.
(And -- RH actually used a link to one of those photos in his correction
to the "answers" page.)

Granted -- I saw those other impedances in what my search turned
up The higher impedances would probably have operated at higher voltages,
and resulted in less wear on the key's or relay's contacts since the
current would be less (though more arcing when the circuit was opened.)
My comment about the impedances was based on the posted link to
the sounder and the posted impedance listed on the relay's nameplate. I
should have edited that out when I found more data, but it was late and
I wanted to finish the newsgroup and go to bed. :-)

O.K. It did look already fired. The one which I had used a
shotgun shell primer as the power to disperse the gas, and that has been
removed after firing. But mine *was* a tear-gas shell. Perhaps modify
the answers to say "Flare pen gun with additional tear gas shell"?

I kept looking for one which looked like the one which you had
to make it unambiguous -- and finally got around to adding "Edwards" to
the search terms and found the photos which showed the extra terminals
as well as labeling it (properly) as a relay.
Enjoy,

And they both *can* be fired from the same pen gun.

1297 might be some sort of spring driven vet's impliment used to squirt
something down an animal's throat or up its other end.
1300 looks like it might be a telegraph "repeater".
i.e. a sensitive relay whose contacts are used to regenerate a strong
signal to be sent down the next length of telegraph line.
