174-2 A vehicle throttle depressor, patent 2,795,151, the patent states:
“This invention relates to automobile foot throttle depressing means and
more particularly to manual automobile foot throttle depressing means adapted
to be interposed between an automobile foot throttle and foot brake pedal so
as to depress the foot throttle and hold it in any one of a plurality of selected
positions so that the automobile engine may be operated at any one of a plurality
of selected speeds without the necessity of an attendant remaining in the vehicle.
Practically all automobiles being manufactured at the present time do not include
a hand throttle which heretofore was usually installed on the vehicle dashboard
and which could be set manually to operate the vehicle engine at a desired rate
of speed. The absence of the hand throttle has posed a special problem for automobile
dealers, particularly those dealers who maintain a stock of used cars, in that the
automobile engines must be operated every day to maintain the engines and other
parts in good operating condition. As an illustration, if an automobile were
permitted to stand without having its engine run fairly regularly for any length
of time, the battery would soon become discharged sufficiently that the engine
could not be started except by an outside source of electrical energy.”

causing the hops to drop from the vines.” patent number 87844
