What is it? CXLV

830 - Ice Saw - for cutting antural ice into blocks during the 'ice harvest'

832 - traffic/secutity camera

Howard Garner in RCM

Hey Rob,

829 = ??? maybe a tin-roofers tool

830 = Ice saw

831 = Ice "Rake", missing the wooden handle. Used to move blocks of ice cut with 830.

832 = Well, the largest part atop the pole is the bracket to hold the other items. The largest piece attached to that is a lamp housing with light sensor above, and the cameras mounted as they are would speak "Video Surveillance", and my guess would be of a parking lot.

833 = ?? not a clue

834 = Jaw set removed from a brace & bit.

Take care.

#830 is used for cutting blocks of ice.

#832 are security cameras

#834 looks like a nutcracker

#830 looks like an ice saw, used to cut blocks of ice from a frozen pond or river.

832- detect the presents of a vehicle at a traffic light ( not very effective they removed them from the area where I work) 834- jaws from a wood brace (hand drill)

832. Traffic control sensor. Used to change the traffic light to green when an emergency vehicle approaches the intersection.

You are probably right but it is just "brace" e.g. brace and bit.

Not in my area. It is just a regular traffic camera. Emergency sensors are much smaller where I live (about the size of the knob atop the light).

830: Saw for cutting ice blocks out of a lake 832: Security cameras or radar guns?

830 is a saw for sawing blocks of ice from bodies of water 832 is a camera for observing traffic at intersections. 834 is a chuck to hold drill bits in a brace.

This answer is correct, though a couple times a week I go through several different intersections that have these for detecting cars in the left turn lane, and they have worked every time. Maybe the system where you work was earlier technology or used different equipment.

Based on what is happening right now in Los Angeles, that one belongs in a museum.

L/A is spending about $1 meg per intersection not only to install sensors, but also cameras that take a pictures of the vehicle and the license plate complete with date and time stamp when you try to run a red light.

Traffic ticket arrives in the mail, stands up in court, and is expensive, at least by my standards.

Here (Saskatoon, Canada), the city installed a red light cam at an intersection near a new auto mall that they developed and encouraged dealers to move to. The dealers are now going to court to challenge the constitutionality of the law, as they're getting the tickets from customers on test drives running the red.

It'll be an interesting case. Finally there's somebody with pockets challenging this cash grab.

If the car is really doing something illegal and is caught on camera, I don't have much problem with automated ticketing.

I think it's reasonable for the owner of a car to be held responsible for its safe use, even if it has been lent out to someone else. In this particular case, the dealer could just have people sign a waiver saying they're responsible for any tickets, same as for rental cars.

Of course, if the vehicle was stolen at the time, then that's a whole different story.

Other countries have had red light cameras operating effectively for decades. Here in Australia they have been in use for something like 30 years.

They cost tens of thousands of dollars not a million, and they don't photograph every vehicle.

They are film cameras, and they have a room full of little old ladies peering at the developed pictures looking for clear violations.

When they get a pic of a car breaking the law a ticket is sent to the registered owner. That owner must either pay the fine or produce an affidavit telling who was driving the vehicle at the time.

Typically car dealerships either just pay them or just shrug and say "dunno who was driving" and try to get away with it.

Portable speed cameras are now in widespread use as well, as of the last decade, which have made it very cheap and easy for them to generate revenue by issuing speeding fines. These cost some $50,000 last I heard (many years ago now).

Occasionally someone goes mockador and destroys or steals one of them, the contractors are not allowed to sit more than about 30m away from them now.

Answers for this week:

829. Railroad hammer

830. Pond ice saw

831. Don't know yet

832. Optic detectors for traffic signal

833. Going to wait a little while before revealing this, unless someone guesses it.

834. Brace bit holder

Links and more info can be found on the answer page, including updates to four of my answers from last week's set:

Looking at it closer it looks like an engineers hammer. The back of the head fits the common square head bolts they used on the switch heads and on the locos.

I have a carb stand that looks like that but it has two of them with a support piece between them.

NY uses buried loops on the lights. Those look like the traffic cameras they have around Albany and Rochester though.

Oh NY does have emergency trip on most lights that are signaled by a strobe mounted on the emergency vehicle. Those use an optical trip.

It's one of them things...

Sounds like a reasonable use for the back of the head.

I'd really like to see that carb stand, any chance you can post a photo or send me one? The owner of this object has a pair of them.
