UNITED STATES PATENT OFFICE CHARLES THOMAS TARVER, 0F HOLLYWOOIJ, ARKANSAS.

BOLT-HOLDER.

To all whom it may concern:

Be it known that I, CHARLES THOMAS TARvnn, a citizen ofthe United States, re-

- siding at Hollywood, in the county of Clark and State of Arkansas, have invented certain new and useful Improvements in BoltIIoldcrs, of which the following is a specification.

This invention has relation to certain new and useful in'iprovements in bolt holders, and has for its primary object to provide a tool of this character which is adaptable to a large number of uses.

An other object is to provide a tool which is simply constructed, may be readily adjusted, and which may be manufactured at a comparatively low cost.

With these and other objects in View, the present invention consists in the combinat on and arrangement of parts as will be hereinafter more fully described and particularly pointed out in the appended. claims, it being understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings forming a part of this specification and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation of my improved tool, showing the parts in position for use asa bolt holder. Fig. 2 is a vertical section of Fig. 1, the ends of the handles being broken away. Fig. 3 is a view similar to Fig. 1, showing the application of the tool as a pipe or rod clamp. Fig. 4 is a de tail perspective view of therstandard. Fig. 5 is a similar view of the adjustable jaw. Fig. 6 is an end view of the handles showing the means for securing the same against movement.

My improved tool is prlmarily designed, to be used as a bolt holder, for preventing therotat'ion of the bolts when the nuts are being removed therefrom. To accomplish this result I provide the handles 5 and 6, the handle 5 having securec hereto at its forward end, the vertical standard? 5 to which the handle 6 is pivoted. The preferred manner of positioning the handle 6 upon the standard is clearly illustrated in Fig. 2, and as shown the lower end of the standard is of approximately circular formation and is dis posed in the opening 8 provided in the handle 6. A transverse pivot pin 9 extends.

in the upper concave surface of the handle The handle 6 isv formed beyond the pivotal pointthereof with the jaw 10, which is adapted to coact with the adjustable and reversible-jaw 11 disposed upon the standard to form a suitable clamp." The bore of the jaw 11 has extending therein a lug or tongue 12 ,whichis disposed in a vertical groove 13 formed in one side of the standard. Asetscrew 14 has threaded engagement in the rear end of the jaw 11 and binds against the standard to secure the jaw in its'adjustcd position. Also adjustably mounted upon the standard 7 and above the jaw 11 there is a second jaw 15, the outer end of which is projected downwardly and then outwardly beyond the forward end of the jaw 11. Secured in the outer end of the jaw 15 there is a holding pin 16, the lower end of which is serrated as shown at 17 for secure engagement-upon the head of the bolt as clearly shown in Fig. 1.

The upper end of the standard is formed with the reduced portion 18 to form a shoulder 18. upon which is seated a head block 19. A clamping nut 20 has threaded engagement upon the upper extremity of the reduced portion 18 of the standard and is adapted to secure the head block against longitu din al in ovem out. is threaded through th outer end of the An adjusting screw 91 block 19 and has its lower end secured in the jaw 15, as will be seen. whereby as the ad justing screw is manipulated the jaw 15 will be moved upwardly or downwardly upon the standard 7.

In order to secure the stationary jaw and the handles movement after the parts have been properly adjusted. a holding bar 22 is bifurcated at its upper end to receive the rear end of the handle 6, and is pivoted. thereto by means of the pin This bar is provided with a plurality of openings 2 -1 any one of which is adapted to receive a spur formed upon the rear end of the handle 5. Thus it will be seen' that any movement of the'handles relative to each other is prevented, leaving the operators hands free to handle the wrench for removing the nut from the bolt.

In the operation of the tool as a bolt holder, thejaw 11 is adjusted upon the standard, and the object through which the bolt is positioned is located between the opposed surfaces of the jaws 10 and 11. The

set screw 14 is now engaged with the standardtb secure the adjustable jaw against ver- .tical movement. The adjusting screw 21 is then turned and the jaw 15 moved down-- a'vardly on the standard until the pin 16 is engaged with the head of the bolt, the lower serrated end of the pin preventing any move ment thereof after the same is engaged with.

the bolt head. The nut 20 is now tightly grooves 28, and recesses 28,

screwed down upon the head block 19, whereby any rotative movement of the jaw 15 is prevented. The holding bar 22 is engaged. with the end of the handle 5 and all of the parts thussecurely held in position- A wrench is now applied to the nut upon the end of the bolt, and turned to quickly remove the nut therefrom, any rotation of the bolt being overcome by the clamping engagement of the tool thereon.

As shown in Fig. 3 when the tool, is tobe used for holding pipes or rods, the jaw 15 and the block 19 are removed from the standard. The adjustable jaw 11 is then removed from the standard and inverted 'so that the toothed upper surface 26 is opposed to the jaw 10. The jaw 11 is now again placed upon the standard and adjusted thereonuntil the teeth engage with the peripherytof the pipe, when the set screw 14 is engaged with the standard to secure the jaw in position. In this manner the pipe is securely held from rotation while thesam is being cut or threaded.

In addition to the aboveuses of my improved tool it is also adaptable to numerous other purposes. The outer end of the handle 5 is enlarged as shown at 27 to-provide a hammerhead, so that should it be.desire:d to-use the tool as a hammer, the jaw 15 is removed and the jaw 11 disposed upon the upper surface'of the jaw 10. The operat' ing handles are locked in close relation by means of the bar 22 when the tool may be conveniently wielded for the driving of bolts, nails, staples, etc. In order to provide means for extracting bolts, s aples or nails, I the jaws 10 and 11 are pr vided at their outer under surface of the end of the handle 6 may be (if so desired) provided with opposed l transverse grpoves,as shown at 30, adapted to receive the ends of wires for the purpose 1 of splicing them together, but this, however, is not essential, and therefore will not be included in the claims.

From the foregoing it will be seen that I have provided a tool of comparatively Sim-- ple construction which maybe conveniently used for a great number of par oses. The variouskparts may be quickly a justedand are of such form as to provide a tool which I is not cumbersome or difficult to handle. It is also strong, durable and highly eflicient in operation. i
