2167. 1-1/2" long:
2169. 6" long, sent in by a visitor who is looking to identify this device that was found in an old machine shop:
2170. 5-1/4" long, take a look at Neatorama for more guesses on this device and a chance to win a t-shirt:

2167. This is a lock for an old telephone dial, a photo of one locked onto a dial can be seen here, although it should be attached to the first hole, not the last.
2168.A wire wrapping tool that is missing the bit and sleeve, it was used for circuit assembly:
This video shows how it is used:
2169. Haven't been able to verify any of these guesses for this device:
-part of a tool grinder
-automatic lube tool holder of some sort
-a somewhat modified air bearing spindle for an end-mill sharpening fixture
-an air infuser to mix with gases
2170. An Alliance 'tenna-rotor', for rotating an outdoor television or ham radio antenna, text on it says "Model No DIR 3; 115 volts 60 cycles AC only 1.5 amps 30 watts; The Alliance MFG Co. Alliance, Ohio, USA". The button is spring returned to the center by a medium strength spring, the two other parts by the arrows are stationary and are used for leverage when moving the button so it can be operated with one hand.
2171. A tool for extracting eyes, stems, and leaves from fruits or vegetables, patent number 757,835:
2172. These are vintage germination trays for testing corn kernels. Each farmer saved some of the best ears at harvest time for next year's seed. Up to 10 kernels were removed from each ear and along with a damp piece of cloth one kernel was placed into each of the small pockets (notice 10 pockets per board). These kernels were kept damp and warm until they germinated. Probably any ear that had less than 90% germination was sent back to the crib to be livestock food. Those ears that had 90% and above were shelled and this was the seed he planted. The kernels with sprouts that came out of the trays were fed to the chickens.
