Answers:


1921. A policeman's tear gas billy club, patent number 1,567,659, which states:

For offensive or defensive use in police work or the like, and more particularly against large gatherings...

I provide a weapon which discharges an incapacitating gas, such as tear gas, thereby effectually coping with the situation without loss of life, but while I prefer to use a gas having only temporary effect, I do not limit my invention thereto, as lethal gases may be employed for use in more serious circumstances.

...capable of discharging a stream of incapacitating gas for a distance of fifty feet or more.

...also useful against barricaded criminals, as has been shown by actual use, since the gas may be readily discharged through a keyhole or under a door.

1922. A Sibley stove, it was invented by Henry Hopkins Sibley to be used by Civil War soldiers to stay warm in Sibley conical tents, it was supposedly patented in 1856, I couldn't find the original patent but did find an improvement to it that was issued in 1918, patent number 1,371,794.





































1923. An ice house, ice was cut from a frozen lake, it was covered with sawdust and stored in the ice house for use during spring and summer. The fence is at the door because there is no ground level floor in the ice house, if a person were to walk through the door, they would fall into an eight feet deep pit. Hanging on the door is a pair of spiked strap-on cleats for walking on the frozen lake.

1924. A stage screw, used to anchor stage braces to the floor, as seen in patent number 648,531. According to patent number 820,655, they could also be inserted into "walls, or upper structure to provide a fixed pint of attachment, so that cables, hooks, guy-ropes, etc, may be readily engaged with ring portions, and thus fastened to the handle, or the device may be used in connection with the various stage-settings and scenery-frames as a fastening means or coupling member."
































1925. Both symbols were found on the fuel gauge of a car dashboard, the arrow indicates that the gas tank door is located on the left side of the vehicle. This symbol is can be seen on most new cars and is especially helpful on rentals or for someone who drives a number of different models .







When there is no arrow, the gas tank location is indicated by which side of the pump that the hose is on, in this case that would be the right side of the car.
Update: I had read that this was correct but it turns out that this is not true for all vehicles.








































1926. A Blakeslee Quickloader, it held seven cartridges that could be loaded into the back of a Spencer rifle, instructions with good illustrations on how it was used can be seen here, patent number 45,469. These must be fairly rare, this one just sold for $4,600 at an auction.
