ROBERT K. MCLELLAN, OF ROCHESTER, NE\V YORK.

MECHANlCAL MOTOR.

SPECIFICATION forming part of Letters Patent No. 709,644, dated September 23, 1902.

Application filed February 5, 1900. Serial No. 4,016. (No model.)

To (ti/Z whom, it may concern:

Be it known that I, Bonner K. MCLELLAN, a citizen of the United States, residing at Rochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Mechanical Motors, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, forming part of this specification.

This invention relates to improvements in mechanical motors which embody shaft-driving mechanism and a main shaft, such as are shown and described in Letters Patent of the United States No. 629,343, and a fly-wheel loosely mounted on and geared to the main shaft, as herein shown and as appears by an application about to be filed by Henry S. Durand for a patent for an improvement in mechanical motors; and the invention consists of the combination, with the shaft and fly-wheel mounted thereon, of certain devices constituting a bearing for the fiy-wheel and means for securing the fly-wheel in its proper position on the shaft, substantially as described and claimed herein.

On the accompanying sheets of drawings, Figure 1 is a side sectional elevation of a mo tor embodying the invention; Fig. 2, a front sectional elevation, on an enlarged scale, of fragments of the motor, the upper section being in the vertical plane containing the axis of the main shaft and the lower section in the vertical plane containing the axis of the shaft shown in cross-section in Fig. 1 behind and below the main shaft; and Fig. 3, across-section of the main shaft and parts surroundingitin the plane 0000, Fig. 2,viewed in the direction indicated by the arrows.

Similar reference-numerals designate like parts in the different views.

The object of this invention is to provide the fly-wheel with a suitable ball-bearing and to render it easy to remove the fly-wheel, with its hearing, from and replace and secure it in its proper position on the shaft and to remove the shaft from and replace it in the frame without disturbing the adjustment of the parts of the hearing.

The frame is a casting comprising the base 1 and uprights 10, connected together at their upper ends by a cross-bar and provided with projections on their outer faces at the ends of the cross-bar 11, of which Fig. 1 shows a cross-section. The outline of each upright viewed from the side is the same as that of the single upright shown in Fig. 1. In bearings on the lower and forward part of the frame is the shaft 2, which projects from the uprights or sides of the frame and on which are the crank-arms 20, extending in opposite directions from the shaft, the crank-arms being connected by a pair of links to a pair of beams which are pivoted on the projections above mentioned at the ends of the cross-bar 11 and which are provided at their lower ends with pedals, from which power exerted by a person operating the motor is transmitted by the beams and links to the cranks.

The shaft 2 carries a large sprocket-wheel 21, which is affixed to the shaft by means of a set-screw 22, extending through the hub of the sprocket-wheel and into a groove in the shaft. Below and behind this shaft is another shaft 8, which is parallel to the shaft 2 and has bearings on the frame similar to those of the shaft 2. It carries a sprocket-ring 30, a sprocket-Wheel 30, and a bevel-gear 31, which are fast on the shaft, the bevel-gear being close to one of the uprights, the sprocketring being near the inner face of the bevelgear, and the sprocket-Wheel 30 being close to the other upright. On the sprocket-wheel 21, which is in alinement with the sprocketring 30, and on this sprocket-ring is a chain 2i, whereby motion is communicated from one sprocket to the other. A shaft 32-f01 example, a propeller-shaft having a bearing at the back of the framecarries a bevel-pinion 34, which extends behind the sprocketring 30 and engages with the bevel-gear 31.

The diameter of the fly-wheel 4E is preferably such that the rim of the wheel extends below the level of the shaft 3, as shown, and on the hub 4: of the wheel is a sprocket-ring 40, by means of which, together with the sprocket-wheel 30" and a chain 35, extending around and engaging with these sprockets, the fly-wheel is geared to the shaft 3. The hub of the fly-wheel contains bearing-rings 41 and 41. These bearing-rings, in which are grooves that form parts of balLchannels, are pressed tightly into the hub 4E. On one end of a sleeve 42, which is fluted at 42 next to its other end, as appears by Figs. 2 and 3, and which is longer than the hub of the fiywheel, is fixed a bearing-ring 43, in which is a groove that matches the groove in the bearing-ring 41 and forms therewith a complete ball-channel. A bearing-ring 43', screwed on the sleeve 42,contains a groove which matches that in the ring 41, and these grooves form another ball-channel. The ring 43 extends over the fluted part 42 of the sleeve, and a set-screw 44, extending through the ring and into one of the grooves of the sleeve, locks the ring on the sleeve, and thus secures the adjustment of the bearing, the balls 45 and 45 being confined in the ball-channels, as shown. In the sleeve which closely fits the shaft2 and in the ring 43 is a groove 46, and in the shaft 2 is a pin 46, which fits in this groove and attaches the sleeve to the shaft, the other end of the sleeve being in contact with the inner face of the sprocket-wheel 21. The fly-wheel, with the rings 41 and 41, travels on the balls 45 and 45, which roll on the rings 43 and 43, these rings turning with the shaft 2 at a lower speed than that of the fiywheel and rings 41 and 41, and the direction of the motion imparted to the fly-wheel from the shaft 2 is the same as that of the motion of the shaft. The bearing is secured in the hub of the fiy-wheel, and its parts are adjusted and locked together, as described, before the fiy-wheel is put on the shaft. That end of the shaft to which the crank-arm shown at the right of Fig. 2 is to be affixed is pushed through the upright shown at the left of the figure and through the sleeve 42 within the hub of the fiy-wheel and through the sprocketwheel 21 and the other upright, and when the pin 46 is within the groove 46 the sprocketwhee121is fastened to the shaft with its inner face against the sleeve 42. The shaft-bearings and loose crank-arm are applied to the shaft either before or after the sprocket-wheel 21 is fastened to it, and then by properly adjusting the shaft in its bearings by turning the bearing-cones on the shaft the sprockets 21 and 40 are brought into alinement with the sprockets 30 and 30, respectively, the distance between the sprockets 21 and 40 being fixed and equal to that between the sprockets 30 and 30.

To remove the fly-wheel or shaft from the frame, it is merely necessary to reverse the operation described in the last paragraph.

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

1. A mechanical motor comprising the combination of: a driving-shaft 2; a fiy-wheel surrounding ,the driving-shaft; bearing-rings forming ball-channels within the hub of the fly-wheel; balls in the ball-channels; asleeve on the driving-shaft within said bearings and fly-wheel, the sleeve being capable of rotating with the driving-shaft; and mechanism to transmit motion from the driving-shaft to the fiy-wheel; substantially as described.
