MOTOR.

SPECIFICATION forming part of Letters Patent No. 447,648, dated March 3, 1891. Application filed October 23, 1890. Serial No. 869,108. (No model.)

To aZZ whom it may concern.-

Be it known that I, THOMAS SUTHERLAND, a citizen of Canada, residing at Stillwater, in the county of IVashington and State of Minnesota, have invented certain new and useful Improvements in Motors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in a new and improved motor, which, while very simple and strong in its construction, will give a high rate of speed, and which can be applied for running an indefinite variety of small machines and the like, and which can be arranged to be run either by hand, steam, or any other suitable power; and my invention will be hereinafter fully described and claimed.

Referring to the accompanying drawings, Figure 1 is a perspective view of my new and improved motor, showing the same arranged with a fly or band wheel on its drive-shaft. Fig. 2 is a top plan view of the same. Fig. 3 is a perspective view showing my invention applied to a small steam-launch; and Fig. 4is a detail view showing my motor applied to a machinists drill.

The same letters of reference indicate corresponding parts in all the figures.

Referring to the several parts by letter, A indicates a short transverse shaft, on which are loosely mounted two drive-wheels B B, which are formed with the beveled teeth B, the wheels being arranged on the shaft A with their cogged sides facing each other, and the periphery of each wheel is formed with a series of teeth B which are here shown as substantially V-shaped. Upon the pivotshaft A between the two drive-wheels B B is pivotally mounted the lower end of alever C, and upon the sides of this lever are pivoted the oppositely-arranged pawls D D. The pawl D extends forward to adapt its free end to engage with the edge teeth B of the righthand drive-wheel B on the forward movement of the lever C, while the pawl D extends rearwardly to adapt its free end to engage with the edge teeth B of the left-hand drive-wheel B on the rear stroke or movement of the lever 0. The beveled teeth of both the drivewheels mesh with a bevel-pinion E, which is secured on the inner end of a shaft F, through which the power is transmitted from the motor.

The operation of mynew and improved mo tor will be readily understood. When thelever 0 is swung forward, its right-hand pivoted pawl D engages with the edge-teeth B of the right-hand drive-wheel, thus revolving the said wheel and the beveled pinion E with which it meshes revolving the shaft F with the pinion. On the rear stroke or movement of the lever (3 the left-hand pawl Dengages with the teeth B of the left-hand drive-wheel, which, meshing with the beveled pinion E, imparts an additional rotary motion to it. Thus the drive-shaft F, through the small bevel-pinion E meshing with the large drivewheels, is rapidly revolved by the said wheels, one of which operates on the forward and the other on the rear movement of the lever C, a continuous and very rapid revolution of the drive-shaft F being thus produced by an easy movement of the lever O.

In Figs. 1 and 2 Ihave shown aband-wheel G, secured on the outer end of the drive-shaft F,and a belt can be placed around this wheel and thus convey power to any small piece of machinery which it may be desired to drive, a hand-lever being shown in the said views to adapt the motor to be run by hand. 7

In Fig. 3 I have shown my invention applied to a small steam-launch, the propeller H being secured on the outer end of the driveshaft F, while the upper end of the drive-lever G is pivotally connected by apitman I to the cross-head of the piston-rod of a steam-engine J. The pawls pivoted to the sides of the drivelever are in this case formed with double ends, as shown, and the upper spring ends of the pawls are connected by rods K to a short centrally-pivoted reversing-lever L. The rear ends of the rods K are pivoted to this lever, one above and one below the pivotal point of the lever, as shown, so that the pawls can be reversed to propel the launch either forward or backward, as will be readily understood from Fig. 3 of the drawings.

In Fig. i I have shown my invention applied to a maohinists drill, and in this compact form it will revolve the point or bit M of the drill with three or four times the rapidity that can be obtained with the drill now in use, thereby performing a far greater amount of work in the same time.

From the foregoing description, taken in connection with the accompanyingdrawings, the construction, operation, and many advantages of my new and improved motor will be readily understood. It will be seen that my motor, the lover of which may be reciprocated by any suitable power-as, for example, it can be connected with the reciprocating rod of a windmill-is adapted for propelling a small boat, for driving a fanning-mill, feed-cutters, churns, grindingmills, washing machines, and, in fact, for an infinite variety of pur poses where a small motor is required.

I do not, of course, limit myself to any one particular use to which my motor may be applied.

llaving thus described my invention, what I claim, and desire to secure by Letters Patent, is-- l. The motor herein described, consisting of the loosely-mounted drive-wheels 13, having the circle of bevel-teeth B on their adjacent sides, and the edge teeth E the lever pivoted between the said drive-wheels and having the oppositely-arranged pawls pivoted to its sides and engaging with the two drive-wheels, and the beveled pinion secured on a shaft and meshing with the two drive-wheels, substantially as set forth.

2. The combination of the drive-wheels 13 B, loosely mounted on a transverse shaft and formed with the bevel-teeth B and the edge teeth 3 the lever pivoted at its lower end between the drive-wheels, the pit-man connecting the upper end of this lever with the piston-rod of an engine, the double-ended pawls pivoted on opposite sides of the lever and having the upper spring ends, the drive-shaft having the bevel-pinion at its inner end and the propeller at its outer end, the centrallypivoted reversing-lever, and the rods pivotally connecting the upper ends of the double-ended pawlswith the reversing-lever, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
