SPECIFICATION forming part of Letters Patent No. 771,534, dated October 4, 1904. Application filed November 20, 1903. Serial No. 181,894. (No model.)

T at whom it may concern:

Be it known that I, WILLIAM P. CLIFFORD, a citizen of the United States, residing at 100-. nium, in the county of Appanoose and State of Iowa, have invented certain new and useful Improvements in Motors, of which the following is a specification.

My invention relates to improvements in motors designed with special reference for use in grain-elevators and similar structures where a simple, efi'icient, and economical elevating power is desired. The invention may also be found useful in small factories and, in fact, in any place where it is desired to operate any 5 light machinery.

The invention is designed to be operated by means of the weight of the team, wagon, and load passing over a spring-yielding driveway divided into sections adapted to generate power by means of mechanism to be hereinafter described and storing up and utilizing the power thus generated by means of weights or springs or similar devices.

With these ends in view the invention consists in the novel construction, arrangement, and combination of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims.

Referring to the drawings forming a part of this specification, Figure l is a view in elevation of my invention as applied to an ordinary grain-elevator. Fig. 2 is a top plan view of the winding-drums with connecting mechanism for running the elevator proper. Fig. 3 is a top plan view of the mechanism located beneath the driveway. Fig. 4 is a rear plan view of the winding-drums, showing a more detailed viewof the connecting mechanism for running the elevator proper and the means for reversing the drums and throwing the same into and out of gear with said connecting mechanism. Fig. 5 is adetail view of one of the ratchet sprocket-wheels of the winding-drums.

Similar numerals of reference indicate like parts throughout all the figures of the draw- In the drawings, 1 designates the frame of an ordinary elevator-building provided with 5 an elevator-box 2, containing the usual ele-. vator-belt and buckets actuated by a driveshaft 3 and pulley 4, receiving power by means of a main driving-belt 5, passing over a second pulley attached to the mechanism to 55 be hereinafter described.

6 designates the supporting-beams of the driveway 7, provided with a platform divided into sections 8, suitably mounted on springs 9, supported on said supporting-beams 6 and designed to yieldingly hold and support the sections 8.

1O designates blocks provided with adjusting-bolts 11, designed to limit the movements of the spring-mounted sections 8 and regu- 5 late the dip or distance said sections will be depressed while being actuated by the team and load passing over the same.

Mounted in suitable journals attached to the overhead supporting-beams 12 above each 7 section 8 is a set of shafts 13, provided with sprocket-wheels 1 4: and ratchet-wheels 15, actuated by means of pawls 16, connected to the sections 8 by means of rods 17.

18 designates sprocket-chains passing over the sprocket wheels 14 and over sprocketwheels 19, secured to the ends of shafts 20, mounted in suitable bearings 21, secured to beams 22, mounted beneath the driveway 7.

23 designates ratchet-wheels mounted on 30 the shafts 20, provided with pawls 24, which prevent the shafts from revolving in a reverse direction. Upon the ends of the shafts 20 are secured sprocket-wheels 25.

26 designates sprocket-chains passing over 5 said sprocket-wheels 25 and over sprocketwheels 27, secured to shafts 28, carrying the winding-drums 29, slidably mounted thereon. The shafts 28 are mounted in suitable bearings 29*, secured to the upright supporting- 9 beams 30. The winding-drums 29 are provided at one end with a sliding clutch 31,

adapted to be thrown into and out of engagement with the sprocket-wheels 27, and upon their opposite ends are provided with sleeves or ferrules 32, provided with ratchetswheels 33, (see Fig. 5,) adapted to be engaged by a series of pawls 34, pivotally arranged within sprocket-wheels 35. The shafts 28 are provided at their ends with ribs or flanges 36, adapted to take into recesses 37 on the interior of the sleeves or ferrules 32, so as to permit the same, together with the attached sprocket-wheels 35, winding-drums 29, and clutches 31, to be moved laterally into and out of engagement with the sprocket-wheels 27 by means of operating-levers 38, pivotally mounted on supporting-arms 39, secured to one of the upright supporting-beams 30, the lower ends of which operating-levers 38 take into an annular recess 40 of the sleeves or ferrules 32.

41 designates sprocket-chains passing over the sprocket-wheels 35 and over sprocket-. wheels 42, mounted on a shaft 43, secured to a supporting-beam 44 by means of a bearing 45. (See Fig. 2.) Carried by and mounted on said shaft 43 is a bevel gear-wheel 46, meshing with a pinion 47, secured to the end of a line-shaft 48, mounted in suitable bearings attached to the frame of the elevatorbuilding. 49 designates a main driving-pulley mounted on said line-shaft 48, over which passes the main driving-belt 5, which passes over and revolves the pulley 4, mounted on shaft 3, which operates the elevator-belt in the elevator-box 2.

5O designates wire ropes attached to and adapted to be wound upon th e winding-drums 29, passing over pulleys 51, suitably mounted on a supporting-beam 52 in the lower por-.

tion of the elevator-building and up and over a second series of pulleys 53, suitably mounted on one of the upper beams of the elevatorbuilding and having attached to their overhanging ends weight-boxes 54, adapted to receive any proper form and suitable amount of weighting material. 55 designates a second pulley mounted on the line-shaft 48 and carrying a belt 56, passing overa pulley 57, mounted on a shaft 58, secured to supportingbeams 59 by means of bearings 60. 61 designates a second pulley mounted on said shaft 58 and carrying a belt 62, passing over a pulley 63, mounted on a shaft 64, secured to the supporting-beams 59 by means of bearings 63. Upon the end of said shaft 64 there is secured a bevel-gear 65, meshing with a second bevel-gear 66, secured to the lower end of a vertically-arranged revoluble sleeve 67, mounted on a vertical shaft 68 and having secured at its top ordinary governor arms and balls 69.

7 O designates a bar pivotally mounted on a supporting-bar 71 and having slidably mounted thereon balls 72, which are adapted to be adjusted to any desired point on the bar 7 0, whereby the speed of the governor and the mechanism controlled thereby may be regulated.

72 designates a bar pivotally secured atits lower end to the bar and at its upper end to a spring 73, which acts as abrake on a pulley 7 4, secured to the shaft 58, around which the spring 73 extends.

The operation of the invention is as follows: The team, with wagon and load, enters and passes up driveway 7 and over the sections 8 of the platform and in passing over the various sections in ascending the platform depresses the same with the connecting-rods 17 and pawls 16, which said pawls actuate the ratchetwheels 15, revolving the shafts 13, sprocketwheels 14, sprocket-chains 18,sprocket-wheels 19, shafts 20, and sprocket-wheels 25. By means of the sprocketchains 26 passing over the sprocketwheels 25 and over the sprocket-wheels 27 motion is transmitted to the winding-drums 29, causing them to revolve and wind up the ropes 50 with the attached weights 54. In this way the operation of winding up the ropes 50 with weights 54 is continued while the team, with Wagon and load, is passing over the various sections of the driveway until the mainfloor of the elevator is reached. If desired, the exit driveway may be similarly equipped with mechanism for still further storing up the energy of team and wagon passing over driveway, if found necessary or desirable. Furthermore, the driveway may be constructed of any desired length found necessary to secure the desired amount of power. After the load has been dumped the winding-cylinders 29 are thrown out of connection or gear with the sprocket-wheels 27 by means of the operatinglevers 38, thus allowing the winding-drums by the pull of the weights 54 unwinding the ropes 50 and causing the sprocket-wheels 35 to be revolved by reason of the pawls 34 coming into engagement with the ratchet-wheels 33. As the sprocket-wheels 27 are being revolved the sprocket-wheels 42 are caused to be revolved by means of the sprocket-chains 41, passing over the same, and the revolution of the shaft 43, carrying the bevel gear-wheel 46, is caused to be revolved, together with the pinion 47 meshing therewith. The revolution of the line-shaft 48, to which said pinion 47 is attached, causes the pulleys 49 and 55,

carried thereby, to be revolved, and these pulleys by means of the belts 5 and 56 transmit motion to the elevator and governor, whereby the same are operated, respectively.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principles or sacrificing any of the advantages of this invention.

29 to revolve in an opposite direction, caused Having thus explained the'nature of my invent-ion and described a way of constructing and using the same, although without having attempted to set forth all the forms in which it may be made or all the modes of its use, I declare that what I claim, and desire to secure by Letters Patent, is-
