THEODORE A. LIBKE, OF WILTON, WISCONSIN.

WINDMILL ATTACHMENT.

Specification of Letters Patent.

Patented Apr. 13, 1215..

Application filed November 25, 1913. Serial No. 802,961.

To all whom it may concern:

Be it known that 1, Tnnooonn A. LIBKE, citizen of the United States, residing at Wilton, in the county of Monroe and State of Wisconsin, have invented certain new and useful Improvements in Vindmill Attachments, of which the following is a specification.

This invention relates to devices whereby a reciprocating motion may be transformed into a rotary motion and with means whereby the intermittent movements of a reciproeating device may be transformed into a continuous or uninterrupted rotary move ment.

Another object of the invention is to provide a device including means whereby intermittent rotary motion is transformed into continuous rotary motion.

Another object of the invention is to pro vide a device including a rotative member adapted to be intermittently actuated, as by the operating rod of a windmill, a continuously rotated device, and with a yieldable means between the intermittently operated device and the continuously rotated device and arranged to store up a certain amount of energy which is transmitted to the continuously rotated device in the intervals between the intermittent movements of the rotative device.

Another object of the invention is to provide a simply constructed device of improved construction whereby the above noted results are accomplished.

With these and other objects in view the invention consists in certain novel features of construction as hereinafter shown and described and then specifically pointed out in the claims.

The improved device may be employed in connection with any of the various forms of intermittently or irregularly actuated mechanism such as windmills, some forms of gas engines, and the like, but is more particularly designed for use in connection with a windmill wherein a reciprocating rod is employed to transmit the motion from the windmill to the mechanism to be actuated, and for the purpose of illustration the device is shown arranged for use in connection with a reciprocating rod of a windmill, and in the drawings thus employed: Figure 1 is a plan view of the improved device. Fig. 2 is an elevation on the line 2-2 of Fig. 1. Fig 3 is a detail in section on the line 3-3 of big. 1. Fig. 4ris a section on the line 4-4 of Fig. 1.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The improved device includes a suitable supporting frame which may be of any required size and of any suitable material and includes end members 10-1l spaced apart and connected by longitudinal brace members 12. A main driving shaft 13 is mounted for rotation upon the members 10--11 as by boxes or bearings 14L15, and a supporting member 16 is likewise supported by the members 1011 and spaced from the shaft 13, the member 16 being preferably supported rigidly upon the members 10-11.

Mounted for rotation upon the shaft 13 and spaced from the frame member 11 is a gear wheel 17, and mounted for rotation upon the supporting member 16 is a pinion 18 with which the gear 17 engages continuously. The pinion 18 is formed with a sleeve 19 preferably integral therewith, and associated with the sleeve 19 is a drum 20, the latter being preferably integral with the sleeve. By this means the pinion 18 the sleeve 19 and the drum 20 rotate together upon the member 16. Engaging around the shaft 13 between the gear 17 and the frame member 11 is a spacing sleeve 21, while a similar spacing sleeve 22 surrounds the member 16 between the pinion 18 and the frame member 11. By this means the gear and the pinion 18 are maintained in position relative to the frame member 11, as hereafter more fully explained.

Extending from the sleeve 21 is an arm 23 having a pawl 2st pivoted at 25 thereto and adapted to engage with the teeth of the gear 17 one at a time. The pawl is provided with a depending weighted portion 26 which operates to maintain the pawl yieldably in engagement with the teeth of the wheel 17. The arm 23 extends beyond the pivot 25, and an operating member, such as the reciprocating rod of a windmill and indicated at 27, is pivoted at 28 to the outer end of the arm 23. By this means as the member 27 is intermittently moved upwardly and downwardly by the action of the wind-wheel, the arm 23 and its pawl 2 1 transmits this movement intermittently to the wheel 17 and thence to the pinion 18 and its drum 20. Extending from the spacing collar 22 is a backing pawl 29 which engages with the teeth of the wheel 17 one at a time and prevents retrograde movement of the members 1718 during the return strokes of the member 27.

Mounted for rotation upon the supporting member 16 is a gear Wheel 30, while a pinion 31 is keyed or otherwise secured rigidly to the shaft 13 and engages with the gear 30. Projecting inwardly from the bod of the ear wheel 30 are a plurality of supporting devices 32, the latter being spaced at equal distances from the center of the member 16, as represented in Fig. 3. A relativelv heavy coil spring, indicated as a whole at 33, surrounds the member 16 with a plurality of its coils at one end bearing around the drum 20 with one terminal of the spring directed through a suitable aperture in the drum 20, as represented at 34:, While the opposite terminal of the spring extends through an aperture in the body of the gear 30, as represented at 35. The periphcry of the drum 20 corresponds to the interior of the spring 33, while the supporting members 32 likewise correspond to and bear against the interior of a plurality of the coils adjacent to the terminal 35, as represented in Fig. 1. By this means the spring is firmly supported at both ends and prevented from lateral displacement when strain is applied thereto as hereafter explained.

Surrounding the shaft 13 between the hub of the gear 17 and the hub of the pinion 31 is a spacing sleeve 36, the sleeve 36 thus coacting with the collar 21 to maintain the gear 17 in position upon the shaft 13 while at the same time permitting the gear to freely rotate upon the shaft. The pinion 18, it will be noted, is of greater thickness than the thickness of the gear 17 and bears against the collar 22, but is free to move in the opposite direction, consequently when strainiis applied tothe spring, the latter is free to move slightly endwise of the member 16, and the pinion 18 by its extra thickness will not be withdrawn from engagement with the teeth of the member 17 by any such movement of the spring and the drum 20 attached thereto. By this arrangement it is unnecessary to rigidly couple the drum 20 and the pinion 18 from movement endwise in an inward member 16, while at the ing sleeve 22 effectually limits the outward movement of the pinion. By this arrangement of the collars 2122 and sleeve 36 a certain degree, of looseness is permitted between the parts, while at the same time they are held constantly in coactive and operative same time the spacposition.

A fly-wheel 37 is mounted rigidly upon the shaft 13, and if preferred, a band wheel 38 may be likewise connected to the shaft 13. The fly-wheel provides the necessary direction upon the momentum to the shaft when rotated, while the band wheel provides for transmitting the motion to machinery of any kind. By this arrangement the spring absorbs a certain degree of the energy of the reciprocating mechanism and transmits it to the driving shaft and its attachment continuously, the absorbed energy of the spring being utilized to continue the motion of the driving shaft during the return strokes of the intermittent device, and thus continuously maintain the motion of the shaft. The fiy-wheel is an important element in the arrangement, as the momentum of the flywheel keeps up the continuous motion and equalizes the same. The spring may be of any required power and increased or decreased in strength to correspond to the machinery with which it is associated.

Having thus described the invention, what is claimed as new is:

1. In an apparatus of the class described, a supporting frame including members spaced apart, a supporting member carried by said frame members, a shaft mounted for rotation relative to said frame members, a pinion fast upon said shaft and hearing by its hub against the adjacent frame memher, a gear loose upon said supporting member and engaging the pinion of the shaft and bearing by its hub against the adjacent frame member, a gear loose upon said shaft, another pinion loose upon said supporting member and engaging the gear of said shaft, a spring connected at its ends respectively relative to the gear and pinion of said supporting member, a spacing sleeve upon said shaft between the pinion and gear thereof, a spacing sleeve upon said shaft between the gear thereof and the adjacent frame memher and thereby maintaining the gear of the shaft in position, an arm extending from said last-mentioned spacing sleeve, a pawl carried by said arm and engaging the teeth of the gear of the shaft, means for applying reciprocal movement to said arm, another spacing sleeve between the pinion of the supporting member and the adjacent frame member, and an arm extending from said last-mentioned spacing sleeve and carrying a backing pawl which engages the teeth of the shaft gear.
