Application filed July 21, 1914. Serial No. 852,273.

To all whom it may concern Be it known that 1, ARTHUR F. PINE, a citizen of the United States, residing at Castle Rock, in the county of Douglas and State of Colorado, have invented a new and useful Bolt Cutter and Holder, of which the following is a specification.

The device forming the subject matter of this application is adapted to be employed for clipping off bolts and the like and for holding a bolt or a nut while the element which cooperates therewith is being turned.

One object of the present invention is to provide a novel plunger structure which cooperates with the jaws.

Another object of the invention is to provide a device of the type above described having bolt holding means and cutting means, the device being so constructed that by the reversal of a part of one of the oper ating levers, either the cutting means or the holding means, may be operative by pressing the levers together. 1

It is within the scopeof the invention to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the 7 details of construction hereinafterdescribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

T11 carrying out the presentinvention there 1s provided a main lever 1 and an auxiliary lever 2, the lever 1 terminating in a finger 3 and the lever 2 terminating in a finger 1. The lever 2 includes a shank 5 which is preferably tapered. The levers 1 and 2 are equipped with ears 6 through which passes a pivot element 7. The levers do not cross at the pivot element 7. On the main lever 1 there is a lug 8 into which is threaded a screw 9, the lug or the screw, depending upon the position of the latter, being adapted to engage the shank 5 of the auxiliary lever 2 to limit the relative movement between the levers when the free ends thereof are closed together.

The auxiliary lever 2 is a composite struc ture and includes an extension 10, the extension 10 of the auxiliary lever 2 and the main lever 1 being provided at their free ends with suitably shaped hand grips 11. The extension 10 terminates in a socket 12, receiving removably the tapered shank 5. At its end, the socket 12 terminates in a hook 14 having functions which will be set out hereinafter.

A latch mechanism is provided for holding the extension 10 of the auxiliary lever 2 on the tapered shank 5 thereof, this latch mechanism in the present instance embodying a lever 15 fulcrumed between its ends as shown at 16 upon projections 17 formed on the socket portion 12 of the extension 10. fit-its free end, the lever 15 is equipped with an inwardly projecting pin 18 adapted to engage in either one of a pair of seats 19 formed in opposite faces of the shank 5 A spring 20 is interposed between the lever '15 and the extension 10 and serves as a means whereby the pin 18 normally is held engaged in one seat 19.

The invention includes a pair of arched '7 jaws 21 straddle the finger portions gripping means. The arms of the U-shaped 3 and 4 of the levers and are-terminally provided with openings 42. Through these openings 42 and through theends of theparts 3 and 4- are passed pivot elements 22. At their crowns and along their longitudinal edges,

the arched jaws 21 are equipped with cutting elements'23l The invention includes a fulcrum member denoted generally by the numeral 24. This fulcrum member 24 is a multi-part structure and its gener'aloutline will be un- I derstood best when Fig. 4 is examined. The

' the arched jaws 21.

fulcrum member'24 lies between the arms of The fulcrum member 24 embodies a block25 shown inverted in Fig. 8.. The block 25 is equipped with openings26. Pivot elements 27 lie in the openings 26 and engage the arms of the jaws 21,

Preferably, the pivot elements are in the form of screws threaded and counter-sunk into the arms of the jaws. In its transverse edge, the block 25 is equipped with a slot 29. The slot 29 is adapted to receive eyes 30 formed: at the ends of the arms of a U- shaped yoke 31 shown in detail in Fig. 7. In the eyes 30 there are openings 32 c0- operating with openings 33 injthe-block 25,,

1 securing elements 39 of any desired form being engaged in the openings to hold the yoke on the block as shown in Fig. 4. The arms of the yoke'31 are provided with threaded openings 24 and in the intermediate portlon of the yoke there is an opening 35 which is of elongated or enlarged form. (Set screws 1 36 are threaded into the openings 34. The

set screws 36 engage the outer edges of guides 37, one of which is shown in Fig. 6,

I .each guide havinga flattened tongue 38 which extends intothe slot29 of the block 25. Owing to this construction, the guides 37 may be moved toward and away from each other by means of the screws 36, but cannot move in the directionof their lengths, owing to the fact that the end faces 40 of the guides 37 are engaged with the block 25 on each side of the slot 29. The inner faces of the guides 39 are grooved longitudinally as shown at41.-

The invention includes a plunger 43 which 7 extends through the opening 35 in the yoke 31 and lies in the grooves 41 of the guides 37, the plunger 43 terminating in a flat tip 44 i which registers in, the groove or slot 29 of the block25. Theplunger 43 terminates in equipped With seats 48.

'as shown in F i 2 the jaws being provided with openings 28 in which the pivot elements 27 are received.

The seats 48 of one jaw cooperate with the teeth 47 of the other aw as willbe understood when Figs. 1 and 2 are noted. The seats 48 and the teeth 47 may be described briefly as a secondary gripping means.

Presupposing that the parts are positioned a, when the hand grips 11 on the respective levers 1 and 2 are pressed together, the fingers 3 and 4 will be separated, tilting the jaws 21 on their fulcrums 27 and bringing the cutting edges 23 together, as shown in Fig. 1. The plunger 43, being received between the guides 37, serves to maintain the jaws 21 in proper relation to each other. It may now be noted that by manipulating the screws 36, the positions of the guides 37 may be altered with respect to each other and with respect to the plunger 43, in order to compensate for wear, and also to effect an adjustment whereby the cutting portions 23 of the jaws 21 may be disposed properly with respect to each other. The plunger 43 is made of tempered steel and is resilient and laterally flexible. Consequently, under an undue strain, the element 43 will yield laterall but will resume its original position after the strain has ceased. In this manner, an undue strain upon the jaws 21 may be relieved.

Presupposing that the levers are in the solid line positions shown in Fig. 1 it will be seen that when the grips 11 are moved toward each other, the cutting edges 23 of the jaws 21 will be moved toward each other also, the gripping portions 48 and 47 of the respective jaws being separated, these gripping portions serving, when the structure is arranged as hereinafter described, to hold a nut, the rounded end of a bolt or the like. When it is desired to use the gripping portions 47 and 48, the extension 10 is removed from the shank 5 and is reversed laterally, so that it assumes the dotted line position shown in Fig. 1. The extension 10 is offset as shown -at 49 and consequently when the extension is positioned as shown in dotted lines in Fig. 1, the levers will be crossed on each other. It is now possible to cause the gripping portions 47 and 48 of the jaws to coactwhen the grips 11 are drawn together. The same motion, therefore, which serves to bring the cutting edges 23 into coacting relation serves also to bring the gripping portions 47 and 48 into coacting relation when the extension 10 has been reversed as hereinbefore set forth.

Owing to the arched form of the jaws 21 it is possible to cut off a bolt or the like at right angles to the axis of the bolt when the levers l and 2 do not lie in a plane which is at right angles" to the axis of the bolt. F urther, owing to the U-shape of the jaws 21, one side of each jaw serves to reinforce the other side thereof, the jaws being thus strengthened and it being possible to use relatively light stock in the making of the aws.

The fulcrum member 24: need not of necessity be used in connection with the U-shaped jaws 21. levers are shown at and the stop mechanism appears at 51. The pivot element is shown at 52 and receives the eye 53 of the plunger 54. The block is shown at 55 and the yoke is shown at 56, the adjusting screws appearing at 57 and the jaws being shown at 58.

The extension 10 may be detached from the shank 5 and the hook 1e may be engaged with the edge of a tire on a wheel. Then when the handle portion 11 of the extension is pressed down, the end of the lever 15 near the hook 14: will be pressed against the fiat countersunk head of a tire bolt and will hold ti]? same while the nut on the bolt is taken 0 Having thus described the invention, what is claimed is 1. In a device of the class described, a pair of pivotally connected levers; jaws pivoted to the levers and provided with cutting means and with holding means; and means for pivotally connecting the jaws between the holding means and the cutting means, whereby when the levers are pressed together at their free ends, the cutting means of the respective jaws will move toward each other and the holding means of the respective jaws will move away from each other; one lever including an offset, removable eX- tension adapted for lateral reversal on that lever of which the extension constitutes a part, thereby to effect a crossing of the levers and to cause the holding means of the respective jaws to move toward each other when the free ends of the levers are pressed together.

2. In a device of the class described, a pair of levers; a pivot element connecting the levers; jaws pivoted to the levers; a fulcrum member to which the jaws are pivoted; and a plunger mounted on the pivot element and adapted to reciprocate in the fulcrum member, the plunger being resilient Note Fig. 11. In this figure, the

and being laterally flexible to relieve an undue strain upon the jaws.
