SPECIFICATION forming part of Letters Patent N 0. 702,086, dated June 10, 1902.

I Application filed June 28, 1901. $erial No. 66,425. (No model.) i

To all whom it may concern! Be it known that I, WILLIAM 0. BENNEa'a citizen of the United States,residin g at Lehighton, in the county of Carbon, State of Penn sylvania, have invented certain new and usef 111 Improvements in Gravity-Motors and Mo hereby declare the following to be a full, clear, and exact description of the invention,suchas' will-enable others'skilled in the art to which it appertains to make and use the same.

This invention relates to gravity-motors and it has forits obj cot to provide an apparatus wherein a weight may be raisedto a suitable elevation and then'permitted to descend, so

that the energy thereof may be utilized forsawing wood, for-churning, or for any other purpose where power is required.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views,Figure 1 is aside elevation showing the complete machine. .Fig. 2 is a section on line 2 2 of Fig. 1 and showing the arrangement of the gearing with the governor and brake mechanism. Fig. 3 is a vertical transverse section through the weight-box.

Referring now to the drawings,the mechanism is mounted upon asuitable base 5 and comprises atower or frame, including parallel uprights 6 of an gle-plates, the sides of which are connected by cross-pieces 7 to form a rectangular frame, and the uppermost cross-pieces support a shaft 8, on which is disposed a pulley-wheel 9. One end of a cable 10 is attached to a bale 11 of a weight-box 12,while the opposite end of the cable is attached to a windingdrum 13, carried by a drum-shaft14,mounted in bearings in suitable supports, as shown. The cable between its ends is passed over the pulley and downward through a guide-passage 14, formed through the bottom of the weight-box and having upwardly-extending walls in the form of a flattened tube,so that the cable may have a lateral movement through the weight-box as it is wound upon or unwound fromthe winding-drum. If the winding-drum is rotated, thecable will be wound thereonto raise the weight-box, and if the drum be then released the box will descend and by its descent will unwind the cable from the drum to rotate the latter. The drum is mounted loosely upon its shaft and at one end "ofthesupports of the shaft.

thereof is a gear-wheel15, having a pawl 16, pivoted thereon in operative relation with a ratchet-wheel 17, fixed upon the drum-shaft, the pawl being held in engagement with the ratchet-wheel by means .of a spring 18. A winding-shaft. 19 is provided and is mounted both forrotatable'and sliding movement in bearings upon the base and carries a pinion 20' for engagement with'the gear of the winding-drum. The pinion is held normally out of engagement with the gear by means of a helical spring 22upon the winding-shaft, one end thereof bearing againsta shoulder on the shaft, while the other end bears against one H By pressing the winding' shaft against the tendency of the spring it will be engaged with the gear on the drum, and by then rotating it the drum will be rotated to wind up the cable and raise the weight-box.

The pawl=and=ratchet arrangement permits of rotation of the drum inde- .pendentlyof the shaft to wind up the cable;

but reverse movement of the drum can be made only with the shaft.

Fixed upon the drum-shaft 14 and at the opposite side of the drum from the gear-wheel 15 is a master-gear 24, which engages with a pinion 25 on a shaft 26, this pinion having also a gear 27 engaged therewith, which is mounted upon a shaft 28, carrying a bandwheel 29, from which leads a band 30 to one member 31 of a cone-pulley, mounted on the power or drive shaft 32', the second and larger member 32 of which is adapted to receive a belt to drive any mechanism that is to be operated.

The pinion 25, above referred to, forms an element'of a second train of gearing, which includes a gear 33, mounted on the pinionshaft, and which through the medium of the pinions 36 and 37 and 38 and the gears 39 and 40 rotates the governor-shaft 41, which car= ries the pinion 38, this governor-shaft being rotated with a high rate of speed, The governor consists of a disk 42, which is fixed upon the shaft 41, and a seconddisk 43, which is mounted slidably upon the shaft,

able plate in the direction of the fixed plate, as will be understood. Mounted slidably upon the shaft 41 is a sleeve 48, having radiating arms 49 and 50, which extend radially of the movable plate, adjacent to one face thereof, and the ends of these arms are bent around the edge of the movable plate and then inwardly to lie parallel with the opposite face thereof, and these ends are provided with brake-shoes 51 in the path of movement of the movable disk, so that when the disk is drawn along the shaft ll it will bear against the brake-shoes with a pressure depending upon the centrifugal action of the weights and which action is of course commensurate with the speed of rotation of the shaft. In this way the speed of rotation of the shaft is governed and therewith the speed of the winding-drum and the speed of the driving cone-pulley. The sleeve that carries these brake shoes may be shifted to apply the brakes to stop the apparatus by shifting the lever 53, which is pivoted upon a standard, as shown, and which has a yoke 5i at one end, which embraces and is pivoted to the shaft. It will thus be seen that the speed of rotation of the apparatus is governed, and it will be understood that the lever referred to may be employed for both stopping the mechanism and releasing it to permit it to operate.

\Vith this construction it will be seen that cone-pulleys of various sizes may be employed and that pulleys 29 of different sizes may be employed to get dilferent speeds of the power-shaft 32 without requiring adjustment of the governor mechanism, which adjustment would be required if the governor were driven from the shaft 32.

It will be understood that in practice modifications of the specific construction shown may be made and that any suitablematerials and proportions maybe used for the various parts without departing from the spirit of the invention.

What is claimed is 1. Adevice of the class described comprising a potential device including a windingdrum, a drive-shaft operatively connected with the drum, a governor for the potential device operatively connected with the drum and means for actuating the governor manually to stop and release the mechanism.

2. A device of the class described comprising a potential device including a windingdrum, a drive-shaft operatively connected with the drum, a governor for the potential device including an automatically-shiftable brake member, a brake-shoe in the path of movement of the shiftahle member, and means for manually moving the shoe' into and out of engagement with the shiftable member to stop and release the mechanism.

In testimony whereof I hereunto sign my name, in the presence of two subscribing witnesses, on the 29th day of April, 1901 WILLIAM O. BENNER.
