To all whom it may concern.-

Be it known that I, EDWIN W. l-IAMMON, a citizen of the United States, residing at Davisville, county of Yolo, State of California, have invented an Improvement in Devices for Converting Oscillatory into Continuous Rotary Motion; and I hereby declare the following to be a full, clear, and exact description of the same. 7

My invention'relates to the general class of mechanisms or devices for converting motion from one form into another, and its object is to convert an oscillatory into a continuous rotary motion in the same direction.

It may be applied to any use to which it is adapted, and is especially useful in connection with the oscillatory motion of a vibratory engine, or such as are commonly known by the name of sector-shaped engines, whereby their motion is conveniently and economically converted into a continuous rotary motion, and is adapted to be readily reversed.

I My invention consists in the novel construction and arrangement of the parts of the device which I shall now fully describe.

7 Referring to the accompanying drawings, Figure 1 is a perspective view of my device. Fig. 2 is a horizontal section of same. Fig. 3 is an end view.

A is a shaft, to which an oscillatory motion may be supposed to be applied from any suitable source, unnecessary herein to show. Firmly secured upon the shaft is a large gear B having a bevel-face with teeth.

C is a shaft mounted horizontally and parallel with the plane of rotation of the gear B. Loosely mounted upon the shaft C, one at each end thereof, are bevel-pinions D, each of which meshes at opposite sides with the gear B.

E are crank-arms, fast upon the shaft C.

F is a slide-rod, the ends of which slide within the extremities of the arms E and are adapted to enter sockets d in the bevel-pinions D.

Upon shaft C is a freely-slidable flange a, guided by suitable means in its movement so that it will not cramp, said means being here shown as the pins cand brackets 0 The slide-rod F passes freely through this flange. Springs G encircle the slide-rod F and lie between the flange c and suitable stops in the shape of buffers f upon the ends of said slide-rod.

H is a rod extending in front of gear 13 and in the diametrical plane thereof. It carries a clutch-shifter h in the shape of separated or spaced plates, which are adapted to engage the periphery or rim of the flange c. The extremities of rod H pass backwardly behind gear B and are pivoted at h to abearing I, so that said rod may move laterally over the face of gear B. Upon the face of said gear are stops 1) adapted to come in contact with rod II from opposite sides.

The bearing I, to which the ends of the rod II are secured, is a rocking one, pivoted upon a center at 1', whereby, by its movement through the operation of a suitable lever, such as J, the upper portion of said rod may be thrown sufficiently close to the face of the gear B to cause the stops 1) to come in contact with it, while the lower portion is by the same movement thrown far enough away from the face of the gear 13 to allow the stops to pass by it without contact. A reverse movement of the rocking bearing I causes the lower portion of the rod to be thrown into the path of the stops, while the upper portion is thrown out of said path.

The operation of the device is as follows: WVhen the rocking bearing I is so turned that the upper portion of rod H is in the path of movement of the stops 1), the gear B onbeing oscillated in one direction will cause one of said stops, by contact with the rodII, to force the whole rod over to one side, and said movement ofthe rod, through its clutch-shifter 7L engaging the freely-sliding flange 0, will cause the latter to move over to the same side, therebycondensing or compressing the spring vGr on that side, which, bearing on the bufferstop f, will cause the slide-rod to move over in that direction, so that its extremity will enter the socket d in the pinion D on that side. Now, as said slide-rod is engaged with the pinion and is also engaged with the crank-arm E of the shaft C, the return movement of the gear B will cause through the engaged pinion a movement of the shaft C in a given direction, while the other pinion is moving freely upon said shaft in a reverse direction. This continues until the other stop I) of the gear B comes up into contact with the rod H from the other side, and thereby moves said rod back again, and this movement, through the clutch-shifter h, will slide the flange 0 over to the other side, causing it to compress the spring G on that other side, and thereby, as soon as the socket cl in the other pinion comes opposite to the slide-rod, the end of said sliderod will thereupon spring into said socket and thus become engaged with the other pinion, and this movement will free it of the first pinion. Thereupon the gear B, returning in the first direction,will cause, through the now engaged second pinion, a movement of the shaft G in the same direction in which it moved in the first instance, thereby continuing in the same direction the rotary motion of said shaft. This will continue until the first stop I) again engages the rod 11 and moves said rod over again for a repetition of the first operation.

In order to reverse the movement it is only necessary to rock the bearing I, so that the lower portion of the rod H will be brought into action, the upper portion being thereby thrown out of action.

The stop K on the back of gear B, Figs. 2 and 3, by coming in contact with fixed stops L, positively limits the oscillation of said gear, and thus effects the accurate operation of the device independently of what may be a slightly-variable stroke of the engine. This is especially of advantage where the oscillatory movement is derived from such an engine as a sector shaped engine, where the oscillating piston is limited by cushioning on steam, and, therefore, may not have a stroke sufficiently accurate for the requirements of the converting mechanism. This necessity for accuracy follows into the construction of the device with regard to the proportions and time of the engaging gear 13 and pinions D, these being such that the alignment of the sockets cl in the two pinions must take place at the limits of the stroke or oscillation of the gear 13. To take place prior to this time would result in reversing the motion.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is,

1. Means for converting oscillatory into continuous rotary motion, consisting of a drivinggear to which the oscillatory motion is initially imparted, independent pinions meshing at opposite sides of said gear and at right angles therewith, a driven shaft upon which said pinions are loosely mounted, and a means comprising a slide-rod having its extremities adapted to alternately en gage the pinions and appliances operated by the oscillation of the gear, for alternately engaging and disengaging said pinions from the pinion-shaft.
