I have noticed phones with a handset (like the one in the image) have a little cover that resembles something like a cold camera shoe under the bottom of the handset's top speaker holder. Is there a use for it? It has a line bump in the middle, but it doesn't go all the way from both sides, it leaves a gap. I have also seem some of them have extra space on the top of the cover, and some don't.

What in the world is a cold camera shoe?

[-] I_Fart_Glitter@lemmy.world 56 points 1 year ago

It's a slot on a camera that you can use to attach accessories, like a microphone or flash. A hot shoe provides power to the accessory, a cold shoe does not.

Well, see what a hot camera shoe is?

Just Leave it outside for a while, and there you are.

Its a non-powered version of a hot shoe, both of which are the thing you use to mount an external flash that's on the top of a lot of (all?) full sized cameras.

Why would you attach an image that does not show what you are referring to?

Okay what's a "cold camara hot shoe" then?

[-] Maven@lemmy.sdf.org 19 points 1 year ago

The "shoe" is the mount. "Hot" means powered, for things like flashes. "Cold" means unpowered, for things like tripods.

[-] echodot@feddit.uk 25 points 1 year ago

Right but there isn't anything that resembles that in the image

If you’re talking about this thing, it serves two purposes. It is the hook that opens and closes the line (hangs up and picks up the phone), and it is used by this thing

to keep the handset from falling off the base when it’s mounted on a wall.

[-] hperrin@lemmy.world 78 points 1 year ago* (last edited 1 year ago)

Or maybe you meant this thing. Yeah, it keeps the handset in when the base is mounted vertical. You can see that it’s slanted in the back.

That’s so it slides in and out on this other slanted lip on the handset instead of getting caught on it. You can take the handset off just by pulling it directly away from the wall.

[-] hperrin@lemmy.world 71 points 1 year ago

Btw, on Trimline phones it is reversible for if you’re not hanging it on a wall. It looks like this when you pull it out.

Exactly this. It’s called a “hook” and when the phone is “off the hook” that’s the thing it is off of. Being off the hook means the phone is powered up and connected to the local loop. When the phone is “on hook” that means it is disconnected from the loop and awaiting the pulsed ring signal.

Desk phones have a reversible hook so that it keeps the button depressed when the phone is in the cradle but doesn’t catch when you attempt to pick it up.

On modem signals in the old days, the + was equivalent to “flashing” the hook, or quickly disconnecting and reconnecting to the loop, and the AT command H1 told the modem to go “on hook” while H0 told it to go “off hook”.

Back before the DTMF network, when everyone used pulse modulated phones, the “pulses” were caused by going in and off hook in a specific pattern. You could actually make a phone call from a rotary payphone by flashing the hook in the pattern that mimicked the rotary dial pulsing the line as it rotated back to home position.

In the really old days, the hand crank served much the same purpose, but actually supplied electricity to the local loop; when the phone was on hook (which was a big metal thing the earpiece sat in) someone else turning the crank would make all the phones on the loop ring; you picked up if the ring matched the number of rings for your extension.

Much better than the older design which cannot be mounted on the wall.

[-] hperrin@lemmy.world 22 points 1 year ago

And the even older design that didn’t even have a bell integrated in the base. The bell was in a separate bell box.

[-] hperrin@lemmy.world 28 points 1 year ago* (last edited 1 year ago)

Or one of these real old designs that didn’t even have a bell. It has a buzzer that’s barely audible (it might even just be the phone’s speaker, idk). Also, the microphone and the earpiece aren’t in a convenient handset.

This one is a replica made in probably the 1970s or 1980s. It’s funny, when it was made it was a replica of something vintage, but now it actually is vintage.

[-] Vacationlandgirl@lemmy.world 15 points 1 year ago

You have a very interesting phone collection and I appreciate you sharing! Unlocked memories I didn't even know I had! 😃

[-] A_Very_Big_Fan@lemmy.world 13 points 1 year ago

Huge props for the unexpected old phone exhibition. It was very interesting, thank you :3

Well, cannot be wall-mounted like the one in your picture but those phones did get wall-mounted in slightly different shape. 1000038469

[-] hperrin@lemmy.world 8 points 1 year ago* (last edited 1 year ago)

Interesting. I’ve never seen a phone like that. Usually the wall mounted versions of the Model 500 had a hook for the handset in the front of the base to hang the handset vertically. This one looks like a different company than Western Electric though. I’m guessing it’s a UK company, because it’s 999 for emergencies (or at least it’s not US). You’ve got me curious enough I feel like I’m about to go down a rabbit hole.

Edit: yep, it’s a UK company called GPO. This is their model 741:

What a cool design! I would love one for my collection.

could had posted a picture of a horse it would be just as helpful but a lot funnier

[-] XbSuper@lemmy.world 67 points 1 year ago

You're description only leaves me with more questions. I have no idea what you're talking about, and therefore have no answer.

[-] echodot@feddit.uk 31 points 1 year ago

Lots of people in this thread answering the question but they're kind of just guessing what you're talking about.

Perhaps you could circle the bit in question because it's either a holder for the headset or a way to mount the entire device onto a wall or something else depending on if we've interpreted your words correctly.

I'm pretty old and even have a camera that uses these things, and took a class on photography; never heard them called a shoe until reading this thread. 🤷🏻‍♂️

English is not my first language and I don't understand what camera shoe mean. But I think I know what you're asking for. That phones can be mounted on a wall and what you're asking for is there so the handset doesn't fall off.

[-] yenahmik@lemmy.world 48 points 1 year ago* (last edited 1 year ago)

It's ok. English is my first language and I don't understand what OP means by "cold camera shoe."

Native English speaker here, I don't have a clue what a "cold camera shoe" means either...

This is the camera shoe for a Sony DSLR

Edit: note that this is a "hot" shoe because it has contacts that can power accessories. A cold shoe is just a mount. You can use to to attach a flash or a microphone for example

[-] FrickAndMortar@lemmy.world 14 points 1 year ago

Not sure if this is what you’re describing, but phones like the one you pictured have a reversible tab for use if you mount the phone to a wall - if the tab is sticking up, it keeps the receiver from falling off the cradle.

Here’s a site selling them, but it has a diagram showing where it’s located:

The intersection of people who aren't five figures into photography and know what a hot shoe is, and people who recognize a wall mount phone trend old.

It's for a hook to keep the handset on when the phone is mounted flat on a wall. It can usually be slid/folded down or removed when its not need.

[-] oleorun@real.lemmy.fan 8 points 1 year ago

It holds the receiver in place. Generally the ridged end is used for wall hanging installs, the flat end stores it away until needed since the desk is horizontal.
