UNITED STATES PATENT ornion LEE T. GOOLSBY AND THOMAS H. GOOLSBY, OF TALMAGE, MISSOURI.

Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed June 20, 1908. Serial N 0. 439,638.

To all whom it may concern:

Be it known that we, LEE T. GOOLsBY and THOMAS H..GOOLSBY, citizens of the United States, residing at Talmage, in the county of Wright and State of Missouri, have invented certain new and useful Improvements in Lifting-Jacks, Wire-Stretchers, and Post-Pullers, of which the following is a specification.

The present invention relates to a novel device which is adapted to be employed either as a lifting jack, a wire stretcher, or a post puller, and the object of the invention is the provision of a simple and inexpensive tool of this character which will operate in an effective manner in any of the above mentioned capacities.

The invention further contemplates a tool which is light and com act in its construction so as to be readi y transported from place to place and which can be readily set up in an operative position or removed therefrom.

For a full understanding of the invention and the merits thereof and also to acquire a knowledge of the details of construction and the means for effecting the result, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation showing the device when em loyed as a lifting jack. Fig. 2 is an enlargec detail view of a portion of the device, the releasing slide being moved downwardly to throw the pawls into an inoperative position. Fig. 3 is a side elevation showing the device when used as a wire stretcher. Fig. 4 is a similar view showing the device as employed for pulling a post. Fig. 5 is an enlarged detail view showing the latch for looking the lever against movement. 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 stock of the tool comprises a pair of spaced side pieces 1 formed upon their op 0- site longitudinal edges with the beve ed teeth 2, the side pieces being connected at one end by a block 3 and at the opposite end by a stand 4. One end of a lever 5 is loosely received between the side pieces 1 of the stock to admit of the lever moving longitudinally upon the stock. Carried by the lever 5 and arranged upon the outside of thestock is a bar 6, the said bar having as aced and parallel relation to the lever and eing connectedthereto at its ends by the blocks 7.

Journaled between the bar and the lever upon each side of one of the side pieces of the stock is a roller 8, the two rollers serving to engage the stock to guide the lever in its movements thereon. A pawl 9 is pivotally connected to the lever 5 upon each side of the stock and these )ftWlS engage the beveled teeth 2 and as the lever 5 is reciprocated each pawl operates alternately to form a fulcrum point for the lever and permit of the opposite pawl being moved into engagement with the next tooth upon the stock.

Loosely mounted upon the bar (5 and having a pin and slot connection therewith is a releasmg slide 10 one end of which has a toggle connection with the pawls 9 through the medium of links 11 while the opposite end is formed with a finger-piece 10. This slide 10 is normally held in an elevated position with the pawls 9 held in a yielding engagement with the teeth 2 of the stock. However, when it is desired to lower the lever upon the stock or to move it toward that end of the stock provided with the stand 4 the slide 10 is moved downwardly and the links 11 then operate to spread the pawls 9 away from the stock. When the releasing slide 10 has reached the limit of its downward movement the point at which the links 11 are pivoted thereto will have been moved beyond the line connecting the points at which the links are pivoted to the pawls and the tension in the s rings 12 connecting the pawls will tend to 101d both the slide and pawls in such position. As soon however as the slide 10 has been moved upwardly and the links 11 brought into a position slightly out of alinement with each other the springs 12 will draw the pawls inwardly against the stock and hold them yieldingly in an operative position. More specifically describing the pawls 9 it will be observed that they are somewhat wider than the stock so as to project upon '0 posite sides reciprocated so that each of the pawls 9 operates alternately to form a fulcrum for the lever while the opposite pawl is being lifted into engagement with the next beveled tooth 2. In this manner the lever is moved upwardly upon the stock and the member under which the end of the lever has been placed will be elevated in the requized man ner. A latch 14 which is pivoted upon the lever 5 is then swung into engagement with the stock to prevent the long end of the lever from swinging upwardly due to the weight upon the short end of the lever.

For the purpose of enabling the device to be utilized as a wire stretcher a clevis 15 is pivotally connected to that end of the stock provided with the block 3 and secured to this clevis is a cable 16 which is designed to be looped around a post or similar member. In the present instance this cable 16 is in the form of a chain and is provided at its extremity with a hook 16 which may be caused to engage one of the links of the chain after the chain has been drawn around the 0st. Passing loosely through an opening in the stand 4 at the opposite end of the stock is a second cable 17 which is detach-- ably connected to a hook 18 upon the lever 5. The free end of this cable 17 is connected to a wire clamp 19 which is designed to grip the fence wire to be stretched. As shown on the drawing this wire clamp comprises a pair of complemental members pivotally connected at an intermediate point to form cooperating jaws and handles, the ends of the handles being connected by the links 19 so that any tension in the chain will tend to draw the handles together and force the jaws into a firm engagement with the wire. In the operation of the device as a wire stretcher the cable 16 is looped about a post and the clamp 19 caused to grip the fence wire which it is desired to stretch. The lever 6 is then reciprocated as in the previous instance and moved longitudinally upon the stock so as to produce tension in the cables and stretch the wire. A take up hook 20 is applied to the stock for engaging the fence wire should it be desired to take a new grip thereon with the clamp 19. This take it claw 20 is pivoted upon a bolt 22 which a so serves as a means for securing the clevis 15 to the stock. A thumb nut 23'is threaded upon the bolt 22 and when it is desired to use the tool for splicing a wire the thumb nut is loosened and the claw 20 turned around so as to 'roject beyond the end of the stock. One ent of the wire may then be engaged by this take up claw while the opposite end is engaged by the wire clamp.

When the device is employed as a post puller the cable 16 is caused to engage some suitable su port such as may be readily formed of '51166 or four poles having their upper ends inclined toward each other and i that purpose.

securely connected to provide a tripod arrangement. The cable 17 at the opposite end of the stock is looped around the post, the cable being provided with a hook 21 for A reciprocating movement of the lever will then operate as in the previous instance to draw the cable 17 upwardly and pull the post.
