To all whom it may concern: Be it known that we, J oHN SPERRY and J OHN, H. EBY, citizensof the United States, residing, respectively, at Kaw city, in the county of Kay and; State of- Oklahoma, and at Carrington, in the county of Wells and State of North Dakota, have invented certain new and useful Improvements-in Power Apparatus, of which the following is a specification. 1

Our invention relates to improvements in power apparatus.

The object of our invention is to a power apparatus which may be adapted to a variety of uses Our invention is particularly well adapted for farm use for such purposes as running corn shellers, grindingamachines, or for drawing the rope of hoisting devices, such as hay hoisting machines.

The novel features of our invention are hereinafter particularly described andclaimed,

In the accompanying drawings which provide readily illustrate the preferred form of our invention.Figure 1 is a plan view, a portion of the power lever being broken away. Fig.2

1s a vertical sectional view, taken on the Fig. 3' is a; verdotted line a,b of Fig. 1;

the dotted line tical sectional view taken on c0Z of Fig. 4. Fig. 4 is ahorizontal section i taken on the dottedline e f of Fig. 3. Fig. 5 is a plan view of a portion tive rack and some of the from the gear wheel which operates it.

Similar characters of reference denote similar parts.

The framework of the machine comprises two vertical side members 1, upon the upper edges of which is secured a horizontal plat form Rotatively mounted in the side walls 1 is a horizontal rotary driving shaft 3, one end of which has secured, to it any suitable type of coupling device 4,; bywhich the shaft may be connected, to the driving shaft of-a corn 'sheller, grinding machine, or any other machine, not shown. ,R-otatively mounted on the driving shaft 3 is a drum 5, provided'at its ends with the heads 6 and 7. Rigidly secured upon the shaft withinthe drum 5,, is a clutch member 8, provided at one end with a-circular rowofratch'etteeth :9, adapted to engage with corresponding teeth 10, disposed concentrically :on' the inner end of the head The outer end-of of the reciprocaparts connected therewith, the rack being shown disengaged adjacent edge of the head 7 is also provided with a circular row of ratchet teet 10, adapted to engage a corresponding row of teeth 9, provided on the adjacent end of a spur gear wheel 11, which is rigidly secured upon the shaft 3 and meshes with a spur gear wheel 12 rota? tively mounted upon a stud 13 secured horizontally to the adjacent side member 1 of the frame. The gear 12 meshes with a horizontal crown gear wheel 14 which is rotatively mounted upon a vertical, rotary controlling shaft 15, which is rotatively mounted in the platform 2 and in a horizontal bar 16, the'ends of which are secured to the two side members 1.

A right angled power lever 17, is rigidly secured to the upper end of the shaft 15 and has its longer arm extending horizontally throughan inverted U-shaped yoke 18, in which the lever 17 is horizontally oscillated relative to the rotary member or crown gear wheel 14. The yoke 18 serves as an abutment against which the power lever 17 has a bearing when said power lever is revolved in the direction indicated by the arrow in Fig.1. To the outer end of the shorter arm 19 of the power lever, is secured a bolt 20 provided at one end with an eye 21 to which is secured one end of a coil spring 22, the other end of which is secured to a bracket 23 which in turn is secured to the upper side of the rotary member or crown gear wheel 14. The function of thespring 22 is to normally retract the power lever 17 in a direction 1 opposite that indicated by the arrow in Fig.

To the outer end of the power lever 17 may be secured a doubletree 24, as shown in Fig. l.

A plurality of supporting rollers 25 are rotatively mounted in recesses provided vertically in the rotary member 14. These rollers rest upon a circular track 27, secured to the upper side of the platform 2, as shown in Fig. 2. Brackets 28 are secured to the upper side of the platform 2, around the periphery of the rotary member 14 and have their inner ends projecting over the upper side of said rotarymember. These brackets serve to prevent the upward tilting of said rotary member. v

Rigidly secured upon the shaft 15, below the platform- 2 is a horizontal spur gear wheel 29, adapted to engage teeth 30 on the a horizontal rack 31, which 1s reciprocatively mounted in downwardly extendingbearings 32, whichare secured to the underside of the platform Pivoted to the upper side of the rack 31, is a pawl 33, which is normally forced against a projection 34 on the upper side of the rack, by means of a spring 35, which is secured at one end to a vertical pin 36, secured to the upper side of the rack 31. The disposition of the teeth 30 on the rack 31 is such that when the gear wheel 29 is rotated in the direction indicated by the arrows in Figs. 1 and 4, the rack 31 will be forced out of engagement with the gear wheel 29, as shown in Fig. 5. When in this position, however, the spring 35 wi.l retain the pawl 33 in engagement with the gear wheel 29, so that if that gear wheel is retracted in the opposite direction the pawl will be forced against the projection 34 and spur gear wheel 29.

the rack will thereby be retracted to the position shown in Fig. 4.

The object of reciprocating the rack 31 is to cause the drum 5 to alternately be locked with and unlocked from the driving shaft 3. To accompish this result the following described mechanism is preferably employed:-A nearly vertical bar 37 has its upper end pivoted to the rack bar 31 and its lower end pivoted to a bracket 33. secured to the inner side of the adjacent side member 1. A horizontal link 39 has one end pivoted to the bar 37 and its other end pivoted to a vertical lever 40, the upper end of which is pivoted to a horizontal pin 41 which extends transversely across a recess 42, provided in the underside of the platform 2. The head 6 of the drum 5 is provided on its outer (ill with a cy.indrical, axial hub 43, to which is secured a collar 44. Encircling the hub 43 and s.idable lengthwise thereon, is a ring 45, best shown in Fig. 3. This ring is normally held against the inner end of the collar 44 by a coil spring 46, which encircles the hub 43 and at its inner end bears against the head 6. The collar 44 and the ring 45 form between them an annular groove 47, in which is located the lower end of the lever 40. The outer end of the rack bar 31 extends through a slot 48 provided in the adjacent side member 1 and at its outer end is preferab'y provided with a hand held 49, by means of which the rack bar 31 may, when desired, be manually held in a position disengaged from the gear wheel 29, as shown in Fi 5.

50 denotes a rope. one end of which is secured to the periphery of the drum 5. This rope is adapted to be wound upon the drum 5 when the power lever 17 is revolved in the direction indicated by the arrow in Fig. 1. In devices such as hay hoisting devices, it is desirable to wind the rope 50 upon the drum so as to hoist the hay in the manner common with such devices. It is also desirable, when the load has been raised to the proper height. to quickly release the drum 5 from the shaft 3 so that the drum may be freely revolved and the rope with- \volve rotation in a like l desired to release the drum 5 from the shaft 13l drawn therefrom. To effect this result the following described method of procedure is employed: l he horse or horses which are attached to the doubletree 24 are driven so as to revolve the power lever 17 in the direction denoted by the arrow in Fig. 1. 'l he power lever in its forward movement will strike the abutment or yoke 18 and its continued movement will cause rotation of the crown gear wheel or rotary member 14 in a like direction Rotation of the rotary member 14 will be transmitted to the driving shaft 3 by the gear wheels 12 and 11. As soon as the power lever 17 is started to redirection will be imparted to the controlling shaft 15 and the Such rotation of the gear wheel 29 will force the rack bar 31 out of engagement with the spur gear wheel and into the position shown in Fig. 5. Movement of the rack bar 31 in this direction will cause the lower end of the lever 40 to be swung, through the intermediacy of the bar 37 and link 39, toward the head (3 of the drum 5. 'l he lever 40 in so moving will bear against the ring 45 which in turn will press against the spring 46 which is of sullicient rigidity to cause it to move the drum 5 lengthwise 011 the driving shaft 3, into a position in which the teeth 10 on the heads 6 and 7 will lcckingly engage the teeth 9 of the clutch member 3 and spur gear wheel 11 respectively. The drum 5 will thereby be in locked engagement and will rotate with the driving shaft 3. thus causing the rope 50 to be wound upon the drum.

'1 he function of the spring 46 is to provide a resilient bearing for the lever 40 so that in case the drum should be in position such that the teeth 10 would strike the outer ends of the teeth 9 the spring 46 would yield and thereby prevent any breakage of the parts.

When it is desired to free the drum 5 from the driving shaft 3, the horses attached to the doubletree 24 are stopped so as to relieve the pulling strain upon the power lever 17. 'lhe power lever 17 being free to oscillate will be retracted by the spring 22 to the. position shown in Fig. 1. Such retraction of the power lever will be communicated to the shaft 15 and gear wheel 29. lietraction of the gear wheel 29 will cause it to engage the pawl 33, as hereinbefore described, thereby retracting the rack bar 31 to the position shown in Fig. 4. Such retraction of the draw bar 31 will, through the intermediaey of the bar 37 and link 39, cause the lever 40 to swing outwardly against the collar 44, thereby sliding the drum 5 lengthwise on the shaft 3 to the position shown in F 3, in which position it will be disengaged from the clutch member 8 and gear wheel 9, and will be free to rotate on the shaft 3. In case that the horses should be stopped and it is not 3, pressure sufficient to overcome the strength of the spring 22 is manually applied to the outer end of the rack barv3l in a' direction such as'will prevent the outward forcing of said bar.

Our invention may be modified in many ways within the scope of the appended claims without departing from its spirit.
