POWER APPLIANCE.

To all whom it may concern:

Be. it known that I, WILLIAM EARLE SHAVER, a citizen ofthe United States, residing at Weldon, inthe county of Dewitt and State of Illinois, have invented new and useful 1mprovements in Power Appliances, of which the. following is a specification.

This invention relates to an improved power appliance, the object of the invention being to provide an appliance adapted to be em ployed for effectively applying power for various operations. I i

In the accompanying drawings, Figure 1 is a sectional elevation of my improved power appliance as mounted for use as a post-extractor. line 2 2 of Fig. 1. Fig. 3 is. an enlargedside elevation of the head-frame, showing the windlass mechanism and gearing. Fig. 4 is a plan View of the same. Fig. 5 is a sectional view of the drum of the Windlass; Fig. 6 is an end view of the same, and Fig. 7 is a side view of one of the ratchet-gears.

their upper toward their lower ends and consist of angle-irons, or, in'other words, they are substantially L shaped in cross-section, the

upper ends thereof being bolted, riveted, or

otherwise secured to the head-frame, asshown' at 3. To the lower ends of the legs are connected feet'or base-irons 4, consisting of ,an-*

gle-plates having flat bottoms .5, which rest directly on the ground and sustain the structure as a whole in a Vertical position. At op-' posite sides the head-frame is provided with bearings 6 for the reception, of a removablethrough bolt, rod, or shaft 7,: which is insertible and withdrawable by endwise movement through the bearings .6, held in place by suitable fasteners 8, which may either consist of cotter-pins, as shown, nuts, or their equiv alent, the said fasteners being inserted through openings in the ends of said bolt, rod, or shaft outside of or beyond the bearings. Surrounding the shaft 7 is a peripheral and spirally-grooved drum 9, upon the reduced'ends l0 of which are placed ratchet gears 11, the

ends of the drum being'squared, as shown, to fit correspondingly-shaped openings 12 inthe ratchet-gears 11.

. Associated with the shaft of the drum is a lever-socket 13, adapted to receive a leverhandle 14 of any suitable length and provided with a bifurcated terminal portion or yoke 15, the arms of which extend outside of the gears 11 and are provided with collars 16, which embrace and are journaled to turn loosely on the shaft 7 just inside of the bearings 6. These collars 16 fit between the bear ings and ratchet-gears 11 and hold the latter in engagementwith the squared ends of the drum. .The yoke 15 also carries ratchet-dogs .17, which engage the gears 11 for turning the Windlass-shaft, while holding bolts or detents 18 are 'pivotally mounted on the head-frame to engage the gears 11 and prevent backward movement of the same. By this construction I and arrangement of parts the shaft 7 may be withdrawn by endwise movement when the fasteners 8 are removed. Upon its Withdrawal the drum 9 and yoke 15 will be disconnected from the head-frame, and as the collarsl6 of the yoke no longer hold the ratchet-gears in engagement with the squared ends 10 of thedrum 9 said gears may-be quickly and conveniently removed, whereby the parts of the operating mechanism are quickly disassociated.

Secured to one end of thehead-frame is a bracket 19, having an outwardly-extending 1 centrally-arranged boss 20 with an inwardly-v extending sleeve 21, in which is journaled a short counter-shaft 22, carrying an operatingcrank 23 on its outer end, the hub portion of which bears against the outer end of the boss 20, the inner end of the shaft 22 being secured by means of a cotter-pin 24 or its'equivalent.

The crank 23 is provided in the outer side of its hub portion with a diametrical notch or groove 25', in which is received a pin or key 26, which is insertible through and removable froman openingin the outer end ofthe counter-shaft 22, thus providing. for the removal and attachment of the crank. Upon theinner end of the counter-shaft 22 is a'pinion 27, which lies beneath and meshes with one of the ratchet-gears 11, whereby the rotary motion imparted to the counter-shaft 22 by the crank 23 is transmitted to the drum 9, around which may be wrapped one end of a rope or cable 28. forming part of a block-andfall mechanism; It will thus be seen that the drum may be operated either by the lever 14 roo 'lIC

or the crank 23, the lever working with a vibratory action and the crank with a rotary motion. By using the lever and crank simultaneously greater power may be obtained to drive the drum than by the use of either alone, as the operation of the crank will continuously drive the drum, while the operation of the lever may be properly timed to secure increased power when the crank is on center. Also by the use of these driving devices the drum may constantly or intermittently be revolved, as desired. The counter-shaft 22 and pinion 27 may be conveniently disconnected from the head-frame by simply removing the pin 26 and sliding the shaft 22 outwardly from its bearing-sleeve 21.

In the adaptation of the machine as a postextractor the block-and-fall mechanism, consisting of the rope or cable 28 and the pulleyblocks 29 and 30, is connected with the machine, the upper block 29 being provided with a hook 31, which engages over a portion of the head-frame 1, as shown in Fig. 1. lower block 30 is also provided with a hook 32, to which is attached a chain 33, which is passed around the post, (indicated at 34.) After the parts have been adjusted in the manner illustrated in Figs. 1 and 2 the lever 14 is rocked back and forth until the post is loosened, after which the crank 23 may be used for more speedily elevating the loosened post.

The power appliance may be otherwise mounted and employed for imparting power for lifting and unloading operations, stretching wires in the construction and repair of fences, and a variety of other uses wherever hoisting, extracting, or stretching operations arev necessary.

Having thus described the invention, what is claimed as new is 1. A power appliance comprising a headframe, provided with bearings, a removable shaft'mounted in said bearings and provided with retaining means, a drum loose on said shaft, detachable ratchet-gears carried by said drum, a lever embodying a yoke which embraces the gears and is journaled on said shaft, operating-pawls connected with the yoke, and detents pivotally mounted on the head-frame, said pawls and detents engaging the ratchetgears.

2. A power appliance comprising a frame provided with bearings, a removable shaft mounted in said bearings and provided with retaining means. a drum loose on said shaft, ratchet-gears removably engaging the oppo- The site ends of the drum, an operating-lever providedwithayokeembracingsaidgears,andprovided with bearing-sleeves interposed between the ratchet-gears and bearings on the frame, whereby said sleeves hold the ratchet-gears in engagement with the drum, operating-pawls carried by the yoke and engaging the ratchetgears, and detents on the head-frame also engaging the ratchet-gears, said shaft serving to connect the drum, ratchet-gears and leveryoke with the frame, whereby the removal of the shaft will disassociate said parts, substantially as described.

3. Acombination-hoist comprising a frame, a shaft journaled therein and removable therefrom, a drum on said shaft provided with ratchet-gears, an operating-lever journaled on said shaft and cooperating with said ratchetgears,and separable auxiliary operating mechanism comprising a bracket removably applied to the frame, a counter-shaft journaled in said bracket, a pinion on said shaft meshing with one of the ratchet-gears, an operating-crank on said shaft, and detachable fasteners at opposite ends of the counter-shaft whereby the shaft is held in operative relation to the bracket and the operating-crank is retained in position on the counter-shaft.

4- A power appliance comprising'a frame, a shaft removably mounted thereon, a drum carried by the shaft, ratchet-wheels removably fitted upon the ends of the drum, and a yoke-lever journaled on the shaft and provided with pawls engaging the ratchet-wheels, said lever cooperating with the frame to retain the ratchet-wheels in engagement with the drum, the construction being such that the removal of the shaft effects the disassemblage of the parts.

5. A power appliance comprising a frame provided with bearings, a shaft mounted in said bearings and removable endwise therefrom and provided with retaining means, a drum loosely journaled upon the intermediate portion of said shaft, ratchet-wheels detachably fitted upon the ends of the drum, a yokelever having collars journaled on the shaft between the bearings and ratchet-wheels and maintaining the latter in engagement with the ends of the drum, and pawls actuated by said lever to turn the ratchet-wheels.

In testimony whereof I aflix my signature in presence of two witnesses.
