Description

March 13, 1928 A. LA ROCHELLE AUTOMATIC LOCK HAND LEVER Original Filed July 23, 1926 UNITED STATES PATENT OFFICE.
ARTHUR LA ROCHELLE, OI CHICAGO, ILLINOIS.
AUTOMATIC LOOK HAND LEVER.
Application filed July 23, 1926, Serial No. 124,461. Renewed February}, 1928.
The invention relates to improvements in automatic hand levers in which a catch overturns automatically, which releases the lever, with the aid of a slot in the lever or material used and a high pressure compression spring to keep the lever locked.
The object of the improvement is to provide a lever detent mechanism in which the detent is automatically controlled by movements of the lever.
One form of the invention is illustrated in the accompanying drawing, in which Flgure 1 1s a side v1ew section of the ent1re lever.
Figure 2 is a plan view of the slot in the lever and the leaf spring.
Figure 3 is an end view of the lever.
The pull and push grip 1 is to pull and push lever 2 which has a flange 3 which keeps spring 4 from moving upwards. Spring 4 presses on socket 5, to which catch 6 is attached, with the aid of shaft 7 which is connected to lever 2. The slot 9 allows catch 6 to move upwards to overturn.
The spring 4 is of higher pressure than to whatever the lever 2 is connected. Catch 6 overturns each time the lever 2 is pulled or pushed.
Spring 4 keeps catch 6 locked. The leaf spring 10 presses on catch 6 in order for it 3 to engage on ratchet 11.
The compressed-air lever check 12 is pro-- vided to check lever 2 when being released.
I claim: The combination of a hand lever pivoted between its ends, and provided with a slot,
a collar on said lever having a slot therein,
a shaft passing'through the lever slot and the collar slot, a catch pivotally mounted on said shaft, a spring for normally holding 40 the catch in alinement with the lever, a shoulder on the lever, a spring of greater pressure than said first mentioned spring, the spring of greater pressure being mounted between the shoulder and the collar and ex- 4 erting a downward force on the collar, a ratchet with which the catch engages.
