DEVICE FOR CONVERTING MOTION.

SPECIFICATION forming part of Letters Patent No. 305,503, dated September 23, 1884;.

Application filed March 3, 1884. (l\'o model.)

To all whom it may concern:

Be it known that I, EMIL BOETTCHER, a citizen of Germany, and a resident of Leipsic, in Germany, have invented a new and useful Improvement in Devices for Converting Rectilinear into Rotary Motion, of which the following is a specification.

In the accompanying drawings, Figures I, II, and III represent side views of the mechanism in different positions. and Fig. IVis an end view of the same with the bearing on one side removed.

Similar letters represent similar partsin all the figures.

K is the reciprocating rod, receiving a rectilinear reciprocating motion, and guided in a cylinder or tube, 0, in the frame 0. To this rod K a rectangular frame, B, is attached,

the lower part of which is guided on suitable ways, f, attached to the bed-plate G. The upper and lower rods, S S, ofthis frame B are provided on their inner sides with suitable teeth, 12 0. Between the rods S S awheel, R, attached to a shaft, W, turning'in suitable bearings, \V, is arranged. This wheel R is provided with teeth Z on part of its circumference, as well as with a long projecting tooth,

P, on one side.

H H are levers turning on suitable centers attached to the rods S S, acted upon by springs F F, forcing said levers inward until stopped by the small pins a a. I

Vis a pulley placed on the shaft \V,to transfer the rotary motion. A

The operation is as follows: The rod K, moving in the direction indicated by the arrows in Figs. I and II, causes the wheel R to turn in the direction indicated by its arrow, in consequence of its teeth Z engaging with the teeth o and the upper rod, S. Before the last teeth, Z Z, leave the teeth 1) in said rod S, the projecting tooth P on the wheel R comes in contact with the lever H on the lower rod, S, moving the same outward against the action of its spring F.

Z has left the teeth in the rod S, the projecting tooth P of the wheel R has passed the When the last tooth,

end of the lever H, which is then moved upward again by the action of its spring F, and

at the same time said tooth P comes in con- 5o ing the beginning of this latter movement,

gradually move around the end of the tooth P. When the rod K comes to the end of that back motion, the tooth Z will have left the tooth o in the rod S, the tooth P will have acted upon the lever H on the upper rod, S, and pass between the end of said lever H and the pin A, attached to said rod S, as soon as the motion of the rod K changes, when the tooth Z of the wheel R will come again into gear with the teeth c on the upper rod, S, and the rotation of the wheel R be continued.

It will readily be understood that this arrangement will operate likewise to convert a rotary motion given to the shaft XV into a rectilinear motion to the rod K.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination of a reciprocating frame, B, with teeth 0 'v on its upper and lower rods, S S, the wheel R, with teeth Z Z Z, &c., on part of its circumference, and projecting tooth P, and the levers H H, with suitable springs, F F, and the projecting pins A A, attached to the rods S S, arranged to operate in the manner and for the purpose substantially as specified.
