Patented Sept. 20, 1932 PATENT OFFICE HENRY A. KOESTER, OF GONROY, IOWA TOOL Application filed February 7, 1931. Serial No. 514,239.

This invention relates broadly to tools, and the primary object of this invention is to provide a tool capable of use in various capacities, as for example a jack, for raising .6 the wheels of automobiles and like vehicles; avise for gripping and holding pipes and similar works; a wire stretcher; or for use in hoisting works and which is also capable of being used for pulling up stakes and the J like driven into the ground. The nature of the invention, together with additional advantages and objects thereof, will be best understood from a study of the following description, taken in connection with the ac- .15 companying drawings wherein:

Figure 1 is a side elevational view of the device.

Figure 2 is a front elevational view thereof. Figure 3 is a horizontal transverse sec- 2 tional view taken substantially on the line 3-3 of Figure 1.

Figure 4c is a perspective view of a combined stationary jaw and chain uide.

Referring more in detail to the drawings, 25 it will be seen that the tool comprises a base 5 from which rises a hollow standard 6 braced at its lower end with respect to the base 5 by suitable brace ribs 7.

A shank 8 is slidably received within the 30 standard 6 and is secured in a desired longitudinally adjusted posit-ion with respect to the standard 6 through the medium of a bolt 9 adapted to pass through an alined pair of openings 10 in registrywith a predetermined 35 opening in the shank 8.

Inthis connection it is to be understood, and as shown, that a longitudinally alined series of openings 10 is provided on opposite sides of the standard 6.

The shank 8 at the upper end thereofhas integrally formed therewith a loop member 11 to the upper end of which is swivelly connected a suspension ring 12. Supported in the lower end of the loop 11 is a combined draw and rope guide 13. The member 13 comprises an elongated block like body that is secured adjacent one end within the loop 11 through the medium of suitable bolt and nut means 14, the bolt of said means passing op posite portions of the loop 11 and transverseshank 8.

1y through the body of the combined draw and rope guide member 13 adjacent one end of said member. Said member 13 remote from its fixed end is provided with a toothed recess 15 on the underside or face thereof.

At its fixed end, the member 13 has rising vertically from the body thereof, a pair of spaced lugs 16 providing therebetween a guide for a hoisting cable, pulling rope, or for the wire to be stretched when the tool is used as a wire stretcher. Lugs 16 are braced with respect to the body of the member 13 by suitable means 17.

j A forked lever 18 straddles the shank 8 and the fork adjacent the free end of the op 0 posite portions of the fork, is pivoted to the shank 8 through the medium of a pivot bolt 19 adapted to pass through said opposite portions of thefork lever, and a selected one of a series of vertically spaced openings 20 pro- 7'; vided in the upper portion of shank 8. The said opposite portions of the forked lever at their free ends are provided ontheir upper edges with concave faces corrugated or otherwise formed to provide teeth 21. The toothed portion of the lever 18 thus provides a pivoted jaw for cooperation with the recess toothed portion 15 of the fixed jaw 13.

Thus a pipe or similar work may be clamped between corresponding ends of the member 13 and lever 18 as is apparent.

Integral with the upper end of the shank 8 is a ratchet bar 22, the same being disposed rearwardly of and in alinement with the As will be also noted, the lower portion of the ratchet bar 22 extends downwardly in spaced parallel relation relative to the shank 8. A dog 23 is pivoted as at 24 in the furcation of the'forked lever 18, and the free end of the dog 23 is normally urged in engagement with the teeth of the ratchet bar 22 through the medium of suitable spring means 25. V

T o facilitate movement of the dog 23 out of engagement with the teeth of the ratchet bar 22, and also to lock said dog 23 in a retracted position, or in a position out of engagement with said ratchet 22 there is provided a catch 26 pivoted at one end as at 27 to the lever 18, and the catch 26 has a conc the foregoing description.

vex edge adapted to engage a lateral pin 28 provided on the dog 23.

By swinging the catch 26 to the right in Figure 1, it will be apparent that dog 23 will be moved out of engagement with ratchet 22 and will be retained out of engagement by reason of the pin 28 engaging in a notch 29 provided in the catch plate 26, Dog 23 beingthus retained out of engagement with ratchet 22 it will be obvious that lever 18 is free to swing about its pivot 19 for releasing or clamping work between the jaw form: V I I combination a shank, a fixed jaw 011 one end ing part of the lever 18 and member 13.

The shank of lever 18. is provided withva socket 30 for accommodating one end of'a suitable'handle 81, suitable means 32. being provided for retaining said end'of the handle within the socket,

Standard 6 on the front side thereoiis provided-with an aperturedlug 33. with which is suitably engaged one end portion of a guide c-lev-is, 44.

To use the tool as a vise or clamp for. pipes,

or. similar; work is thought apparent from To use, the tool as: a vehicle jack, the combined fixed jaw and chain guide 13 may be removed from the loop 11 and lever 18 may be swung about its pivot upon engagement with the wheel axis or other partiof the vehicle for jacking up theivwheel orpart of the vehicle desired. Dog 23 engaging with ratchet ba r 22-will retain the lever:

15in position against. the weight of the vehiQ-l-e for retaining the wheelor part of the vehicle at the desired height.

To use the tool as-a stump orstake puller,

the cable that is engaged with the stake or:

stump, in the usualf manner may have a portion thereof passed between the jaw forming. portions of the lever 18 andthen continued upwardly and passed through the loop. 11 to. be engaged with the guide lugs 16 between. the lugs in any suitable manner. The portion oi} the pulling cable or chain passed between the aforementioned portions oi the lever=18.-,

may be-sui-tably engaged by the lever and ob-- viously by rocking the lever 18 sufficient, pull willbeflexerted on the chain for uprooti-ng the stump or stake as the case may be.

When used such a capacity,the clevis 44. may be utilized as a guide for the pull cable. i To use the tool as a; wire stretcher, the strand cf wire tobe-stretched may be passed between the lugs 16 over the member-13 and '3 then downwardly to engage thejaw forming portions of'the lever 18 and lever 18 may then berocked in: a suitabledirection for stretching the wire in a manner thought apparent;

' The ring- 12 providessuitable-means for sus: pending the tool from the cross, beam of'a ing well pipe strings.

Erom the foregoing-then it, will beseen that IE :have devised a tool that is readi-lyadapted torause in many varied; capacities, thus ren-= dering the device especially useful for farmers and the like living in the oil regions of the country.

Even though I have herein described the preferred embodiment of the invention, it is to be understood that the same is capable of further changes, modifications and improvements coming within the scope of the appended claim. I

Having thus described my invention, what I claiin'as new is:

r A tool of the class described comprising in of the shank, a movable jaw pivoted to an intermediate portion of the shank and cooperable with the fixed jaw, said'shank having integral therewith a ratchet bar, a dog pivotallymounted on said movable jaw engage-J able'with said ratchet bar yieldable' means normally retaining saiddog H1 engagement with the ratchet bar, andmeans for eii'ecting; movementv of the dog out. of engagement with the ratchet bar and subsequently locking the dog in the lastreferred toposition.

In testimony whereof I aiiix my signature.
