LEVER MECHANISM.
Specification of Letters Patent.
Patented Dec. 29, 1908.
Application filed May 22, i907, Serial No. 375,153. Renewed May 20, 1908. Serial No. 433,940.
To all whom it may concern:
Be it known that I, FRED BISZANTZ, residing at Chillicothe, in the county of Ross and State of Ohio, have invented certain new and useful Improvements in Lever Mechanisms, of which the following is a specification, reference being had to the accompanying drawings.
My invention relates to improvements in lever mechanism, and an object of my invention is to provide a mechanism of this kind which will be simple and compact in structure, eflicient in operation and particularly adapted for use with automobiles.
In the drawings illustrating the principle of my invention and the best mode now known to me of applying that principle, Figure 1 is a side elevation looking in the direction of the arrow A in Fig. 2; Fig. 2 is a rear elevation of my new lever mechanism; Fig. 3 is a detail of the latch or plunger-dog; 4 is a detail of the lever-locking devices; and Fig. 5 is a sectional detail showing the engagement of the plunger-dog or latch with one of the levers.
The supporting-standard a is forked, being provided with the arms I) the ends of which are connected by the curved-bar 0 formed with the rib d. The latter is provided with an opening e. Supported by the standard a is the shaft f upon which is mounted free to rotate the hollow-shaft or sleeve 9 which carries the crank-arm h. Upon the hollowshaft or sleeve 9 is mounted another sleeve i free to rotate thereon and provided with the crank-arm Secured to the sleeve 'L is a lever 76 the upper end of which hooks over the uaper edge of the curved-bar c and is provi ed with a recess m. Firmly secured to the sleeve 9 is the lever n the up er end of which is formed with a recess 0. oosely mounted upon the sleeve 9 is the operating the handle g of which is recessed, and there y adapted to receive the plunger r against the shoulder s of which presses the upper end of the coil spring t the lower end of which presses against the bottom wall of the recess u. The plunger r extends down along the side of the lever 10 and passes through the guide-plate c. The lower end of the plunger r is provided with the dog or latch to. The latter is formed with a lug x which is adapted to pass through the opening e and to fit snugly in the recesses m and 0.
The crank-arm h is connected by the linkrod y with the transmission gear (not shown) of the automobile in such manner that when the lever 72 is thrown in one direction the lowspeed gears will be made operative; while by throwing the same lever 'n in the opposite direction, the reversing mechanism of the machine will be made operative. Similarly the crank-arm j is connected by the link-rod 2 with the transmission gear of the automobile in such manner that when the lever 7c is thrown in one direction, the intermediate-speed gears are made operative; while when it is thrown in the opposite direction, the high-speed gears are made operative. When the recesses m and 0 register with the opening 6 in the rib d, the levers 7c and n are each in neutral position.
It will be obvious from what has just been stated that in order to reverse the driving mechanism, the operator must go to the trouble of depressing the plunger 7' so as to engage the lug a: in the recess 0. This will avoid bad accidents now so frequent because of reversing the machine when it is not intended to do so. Further, the lug or ear 0: will be locked in the recess of the lever by the rib (i, when either lever k or n is thrown from its neutral position. Thus, it will be perfectly obvious that the lever Ir must be brought to its neutral position before the lever n can be engaged by the ear r, and vice versa.
Each of the link-rods y and z is formed with recesses 2 adapted to receive the end of a spring-controlled plunger 3 slidably mounted in the sockets 4 formed in the walls 5 of the transmission-gear casing. The plunger 3 will automatically lock the link-rods in their several positions, when the recesses 2 come into register with the inner end of the plunger.
I claim:
1. In a lever mechanism,- the combination of a support; a bar mounted upon said support and formed with a curved rib, said rib being formed with an opening; a lever the upper end of which is formed with a recess and adapted to travel along one side of said rib; a second lever formed with a recess and adapted to travel along the opposite side of said rib; an operating lever; and a plunger mounted upon said operating lever and formed with a lug adapted to pass through the opening in said rib and to engage alternately in each of the recesses in said levers, said lug being locked in each recess by the rib on said bar.
2. In a lever mechanism, the combination of a support; a bar mounted thereon and formed with a curved rib, said rib being formed with an opening; a lever the upper end of which is formed with a recess and which travels along the upper side of said rib a lever the upper end of which is formed with a recess and which travels along the under side of said rib; reversing mechanism connected with said last-named lever; an
operating lever; a plunger mounted upon said operating lever and formed with a lug adapted to pass through said opening and to engage in each of said recesses alternately;
