SPECIFICATION forming part of' Letters Patent No. 758,578, dated April 26, 1904.

Application filed March 21, 1903. Serial No. 148,996. (No model.)

class which is especially adapted for operation by hand.

Among numerous objects attained by this invention and readily understood from the following speciiications and accompanying drawings included as a part thereof is the production of a simplified and inexpensive mechanical motor embodying essential features of adaptability, utility, and general eiiciency, which render the device readily adjustable for reverse action, insures a positive uniform action, and transmutes manual energy into accelerated mechanical energy.

rFhe above mentioned and other objects equally as desirable are attained by the constructions, combinations, and arrangement of parts as'disclosed on the drawings, set forth in this specification, and succinctly pointed out in the appendedclaims.

With reference to the drawings filed herewith, and bearing like reference characters for corresponding parts throughout, Figure 1 is a view in perspective of my improved mechanical motor as preferably 4embodied and adapted for the applicationof manual power to operate the same. Fig. 2 is a plan view of the motor on reduced scale. gram showingthe pitch-lines of the gears of the motor in relative position and the shafts therefor shown in vertical transverse section on line 3 3 of Fig. 2 looking as the arrows indicate and also vshows the carrier for the drawing-wheels in relative position. Fig. 1

is a view in side elevation of the carrier on large scale, and Fig. 5 is a View of the head of the carrier in transverse section on line 5 5 of Fig. 4 looking as the arrows fly.

This invention incorporates a driver, as 10, which includes a pair of power-transmitting Fig. 3 is a dia-v wheels, as 11, each of which preferably consists of a spur-gear of comparatively large diameter, and these gears are suitably mounted Y for independent rotary movement on a shaft, as 12, conveniently disposed at one end of a main frame, as 14;, in a horizontal position and supported in suitable bearings, as boxes 15, mounted on the side piecesof the frame in any convenient manner. These transmitting wheelsV are driven independentlyby means ofdriving-wheels, as 16, which in the present embodiment compriseV spur-pinions of comparatively small diameter which are suitably rotatably mounted in engagement with respective transmitting-wheels on a rotatable carrier, as 17, which is suitably mounted concentric withsaid transmitting-wheels for reciprocative action, and as now considered includes three radially-disposed parallel arms 18 set at suitable separation to receive said wheels loosely, and having suitable bearings, as 19, at the inner end adapted to rotatably support the carrier on shaft 12, whereby the carrier is conveniently supported concentric with said transmitting-wheels. Y At the outer ends of these arms is secured a suitable head, as 21, which is adapted to tie the arms together, and this head is formed with suitable recesses, as 22, in the under surface to receive loosely the driving-wheels, and suitable apertures are formed in the end walls of these notches to conveniently afford bearings for the n t axles, as 28, to which these driving-wheels are secured, and these bearings are arranged at suitable points to rotatably support the driving-wheels in engagement'with the transmitting-wheels.

Suitable means are embodied with each driving-Wheel 16 to lock it from rotation during movement of the carrier when operated in one direction and allow said wheel to rotate freely y when the movement of the carrier is reversed, so that reciprocal action of the carrier will be thereby transformed into continuous rotary movement of the transmitting-wheels through the medium of respective driving-wheels when they stand locked.

As now considered, the, means for locking the driving-'wheels comprise rollers, as 24, one of which is associatedwith each of said wheels,

and these rollers are arranged in contact with the axles of said wheels in seats, as 25, formed longitudinally in the walls of the bores of the outer bearings for said axles. These seats for the rollers each comprise a notch or recess arranged longitudinally in said wall and formed with a semicircular base side substantially equal in radius to the radius of roller 24 so that the roller will be free to rotate when resting therein in contact with the axle of the driving-wheel, and the back side wall of this notch or recess is extended upwardly from the base at a substantially elliptical curve,

which converges to the wall of the bore of the bearing, so that the roller will be thereby forced into positive binding contact with said axle when shifted laterally from the base of the seat, and thereby made to serve to lock the driving-wheel from rotation. As now considered oppositely disposed seats 25 are formed in the bore of the outer bearings for each of the axles 23, so that the rollers can be transposed in position to reverse the direction of rotation of the transmitting-Wheels, and a suitable upwardly-extending handle, as 26, is conveniently removably seated in the head of carrier 17,by which the carrier is conveniently moved reciprocally to drive the transmittingwheels.

By employing the rotatable driving-wheels the construction of such a driver is greatly simpliiied and a positive connection of the carrier with the transmitting-wheels is insured. Furthermore, the reversing of the application of the driving power relatively to the transmitting-wheels is readily accomplished and the driver rendered capable of adjustment to drive the transmitting-wheels in the same or in opposite directions without requiring a great multiplicity of parts.

1n the present embodiment suitable mechanism is embodied with the driver to concentrate the energy delivered by the transmitting-wheels, and as now considered this meehanism comprises a main shaft 27, supported parallel to shaft 12 in suitable journals 28, a pinion 29, fixed to said shaft in mesh with one of the transmitting-wheels, a second pinion 33, also iixed to the shaft at one side of the other transmitting-wheel, and a pinion 31, rotatably supported in mesh with said second pinion and with last said wheel, and a suitable fly-wheel, as 32, is preferably iixedly mounted on shaft 27 and a power transmitting wheel, as a sprocket 38, is also fixed to said shaft.

As now considered the main frame 14 comprises end sills, as 34, side pieces 39, secured upon said sills, and a beam 35 intermediate said side pieces and secured to said sills and the journals for the main shaft, and the bearings for the shaft 12 of the driver are mounted on the side pieces of this frame, while a bearingbox, as 36, is arranged on the beam 35 to support one end of an axle, as 37, for the intermediate pinion 31, while the opposite end of said axle is suitably supported by forming an aperture in the adjacent side piece of the frame to receive same.

Granted construction of such a m`otor,an operation thereof would occur substantially as follows: The rollers 24 are first disposed in respective seats which lie opposite, as shown in Fig. 5, and the carrier is then forced to movefor instance, to the left, as viewed in Fig. 1. This will cause both driving-wheels to rotate until the roller shown on the left in Fig. 1 is raised in its seat by action ofrespective axle 23, and thus brought 'to bind upon said axle and lock the respective driving-wheel, when the respective transmitting wheel will be forced to rotate with the carrier, while the roller at the opposit-e side of the machine will remain in the base of its seat and rotate with the axle of its respective driving-wheel until the movement of the carrier is reversed,\vhen this roller will then be forced Vinto binding position and the opposite roller carried to the base of its seat by the reverse action of the axle with which it contacts. Thus the transmitting-wheels will be driven in opposing directions and serve to drive the main shaft of the concentrating mechanism continuously in one direction through the medium of the pinions secured thereon and the intermediate pinion.

This motor is simple of construction, positive in action, and has few parts likely to get out of order, and can be employed in numerous places where a motor of this class would be useful-aa for instance, it can be used to drive rotary fans, hand-cars, boat-propellers, wheeled vehicles, and numerous other mechanism requiring the application of driving power.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, is-
