UNITED STATES JOHN AARON PETERSON, OF KANE, PENNSYLVANIA.

STAPLE FULLER.

Application filed April 14, 1925.

To 0/." iii/awn it may colic-era:

Be it known that L dorm ranox Pic'rnnsorr. a citizen 0% the l nited States of America, and a resident of Kane, county oi Mcl lean, tit: 'e of Pennsvlvania, have invented certain new and usei'ul Improvements in and Relating to Staple Pullers, of which the following is a specification.

This invention relates to certain impl'OYHnBlliF in staple pullers; and the nature and objects of the invention will be readily recognized and understood by those skilled in. the arts involved in the light of the following explanation and detailed description of the accompanying drawings illustrating what I at present consider to be the pretcrrcd embodiments or mechanical expressiOlis of my invention from among various other forms, embodiments, combinations, and constructions of which the invention is capable within the spirit and scope thereof.

More particularly the invention is directed and deals with a staple puller primarily adapted for use in erecting and repairing fences of the wire types in which the wire is secured and fastened in position by staples or similar fastening means, on and to wood or similar material posts or supports. The staples securing and fastcning fence wire to the supporting posts are of necessity driven firmly onto the wire to bind the same against the posts, and the heads of such staples are generally found to be in such osition against or partially embedded in tie posts as to make it exceedingly diliicult to force the conventional staple pulling implements or tools thereunder to secure a suflicient hold to pull or draw the staples. This difiiculty is encountered particularly in withdrawing staples which have been in position a considerable period of time and subjected to the action of the elements, as in withdrawing staples to repair or mend fences.

Therefore, one of the main objects of the present invention is to provide a staple puller which is capable of pulling or drawing staples easily and quickly from the member into which driven, irrespective of the condition of a staple or the position thereof in the member.

A further object of the invention is to provide a staple puller for efficiently withdrawing or extracting staples, which puller also forms and provides a hammer for driving staples and for general use where a Serial No. 23,077.

hammer is desired, the construction and arrangement being such that a compact, readiiy portable, and easily operated tool or implement is formed.

A further object of the invention is to provide a staple puller which also forms a hammer, and in which the hammer forming member oi? the device is utilized to cooperate and function with the staple pulling member to secure a hold on a staple and extract the staple from the element in which driven.

Another object ol the invention is to provide a staple puller and driving hammer, with a wire cutting member operated by and in cooperation with the hammer member and the staple pulling member of the implement or tool so formed.

A further object of the invention is to provide a staple puller which is adapted to also form a driving hammer, with an arrange ment of operating handles to permit of the implement being readily grasped in one hand for use as a hammer, or to be grasped in and by both hands for holding and operating the members thereof in using the implement as a staple puller.

A further object of the invention is to provide a combined staple puller and hammer with locking mechamsm for securing the members of the implement in hammer forming relation and for releasing the members to permit of their operation as a staple puller.

Another object of the invention is to provide a combined staple puller and hammer with an arrangement for attaching thereto and supporting a container therefrom in such a position that the staple puller and hammer in hammer forming relation forms a readily grasped supporting handle for the container.

A further object of the invention resides in the provision of a compact and eflicient staple puller and hammer of simple construction which will be durable in service and capable of manufacture at low cost.

lVith the foregoing main objects, and certain other objects and results in view, which other object's and results will be readily apparent to those skilled in the art, the invention consists in certain novel features in construction and in combination and arrangement 0t elements, as will be more fully and particularly referred to and specified hereinafter.

Referring to the accompanying drawings in which similar reference characters refer to corresponding parts throughout.

While the embodiment o t ll or of the invention dis-"lowed a herewith is primarily adaptcu the erection and repair oi 'cnc 'ire types, the intention such. use. but is adapted in extracting fasteners ot type and as a hammer o1": unrver ppllCil-iiill. The mechanical. expression ini-cntion hereott is presented purely ample and not oi limitation to the principles and features of the inv tion. and the use tliereo in the erection and repair of fences permits oi more clearly bringii'ig torth these principles and 'leaturcs because the problems solved, and disadvantages overcome thcreby are encountered in a high degree in such use.

According to the embodiment iilu:-:1r:i.ted in the acconipany "mgdrawii'i s. a staple puller of the invention includes a pair oii' lover or arm members and 1. which are pivotally connected and joined at one end to each other in substantially parallel normal relation. by a transverse pivot pin or the like 12. In the present instance the end of member .1 l. is formed with the lozri tudii'ial. ear l t which is reeo'rcd and (i between the parallel spaced ears 1"; o l: i' ber 10.; with pin 12 extending d "Qfli tliicsc ears, as will be clear by roi'crencc to r t in particular. ln this manner the lower members 10 and ll are pivotally joined at one end and at the opposite ends for swinging movement toward and from each other.

The free end of the member 10* is proyided with a transversely disposed staple engaging and fulcrum forming head 20, flattened at the inner end 21 adjacent the member ll, and extended outwardly from member 10 at the opposite end to form the pointed staple engaging end 22 which is rename bent or curved inwardly toward and longitudinally of the member 10 and has the outer side thereot longitudinally curved to provide the fulcrum or bearing surface 23, as will be more fully explained and referred to hereinafter. The lever member 10 is formed of a greater width for a portion of its length adjacent to and extending from head toward the pivoted end of the lever and this widened portion is formed with opposite concave sides 24. to provide a hand or linger hold in the operation of the staple puller.

The arm 11 is provided at its free end with the transversely disposed hammer iorn'iin r head extended outwardly a distance beyond the member ll. and at its inner end ill adjacent head 20 it is flattened to engage the flattened inner end 21 of head 20. The inner ends 21 and 331 ot the opposite heads 20 and 30, respectively, are extended a slight distance beyond the arms 10 and 11, respectively. while the heads are alined longitudinally at their inner ends so that in normal position of arms 10 and 11 swung toward each other these heads abut and space the arms a slight distance apart, as clearly shown by Figs. 1. and 2 oi the drawings. Arm 11 is formed with handle 32 disposed longitudinally and forming a part thereof and extending outwardly and spaced therefrom throughout a portion of the lengrtl'i of arm 11 from the pivoted end thereof to a point intermediate head 30 and the pivoted end. This handle 32 provides for the operation of arm 1.] and hammer head 30 in forcing the pointed end of head 20 into engagement with a staple.

Mechanism for detachably locking the heads 20 and 30 with arms 10 and 11, into position swung together. is provided, and in the example hereof comprises a strip of resilient spring material forming" a clip 33 pivotally mounted at one end to the outer t'oii'ward side of head 30. adjacent the. inner end thereof, by a pivot pin 84-, and provided at its free end with a stud or projection on and extending from the inner side of the clip The head 20 is termed with a depression 26 (see 3) and the head 30 is formed with a similar depression as (see Fig. 2) for receivingthe clip stud 35 and confining the clip 33 in the desired position, as will be readily apparent. When it is desircd to lock the members 10 and 11 into position, the spring clip 33 is swung over onto head 20 until stud snaps into the depression 26, thus securely holding and lockthe members and heads 20 and 30 to gether. To release and unlock the members 10 and 11 with their respective heads, clip is sprung away from head 20 and then swing back onto head 30 and there retained in position by stud 25 in depression 36.

:l, "further feature of the invention prorides for operation of the staple pulleras a mater; A cutting blade 4t) is detach- V ably. mounted by means of a screw-threaded shank '41 on the inner side edge of the lever member, 10, adj acent and in proximity tothe 'pivote'd'end thereof, with the blade inpositionfdisposedlongitudinally of the members 10"a1nd 11. The blade 40 extends such a distance from member 10 as to practically lightly touch orengage the opposite por-v tion {i2 of the member 11 with the members I swung together, which thus forms a base for rece ving a wire to be severed or cut.

y the foregoing mountingand disposition of blade 40 adjacent the pivoted ends of memhers 10 and 11, the full effect of these members as longlevers can be secured in a cutting operation, the wire being placed on the cutting base 42, and the members swung together to cause blade 40 to sever the wire.

The blade 40 can be detached and replaced by a'sh'arp blade when found necessary.

A'hook 50 is pivotally mounted transverse ly'of and through the widened, grip forming portion of member 10, with the hook and bill thereof disposed transversely across and and freely swingable longitudinally of the outer side edge of member 10. With the staple puller disposed in position with the member lOlowermost, as shown in Fig. 1,

the hook 50 depends downwardly therefrom vtin position to receive and hold the bail or handle of a bucket or other receptacle, and by locking the heads 20 and 30 together with clip 33,the handle 32 can be grasped and a receptacle secured to hook O readily trans ported, with the staple puller and hammer, as a unit, disposed horizontally and forming a holder and handle for the receptacle.

In operation-and use of the staple pulling and hammer forming implement above described, when it "is desired to pull. or

draw a staple, the clip 33 is swung to unlock heads 20 and 30, and arms and 11, The staple engaging and drawing head is then placed with the pointed end 22 thereof in position to engage and pass under the head of a staple, as clearly indicatcd by Fig. 1 of theaccompanymgdraw I on ings. By grasping the widened and con cave-sided portion 25 of arm 10 with the fingers of one hand to hold head 20. in 7 position, and grasping handle 32 of arm 1 in the other hand, arm 11 is raised and lowered to pound or strike hammer head onto head 20 and drive or force the pointed end 22 thereof into the desired position under and engaging thestaple head. After I the end 22 of head 20 is driven or forced into staple engaging position, the arms 10' and 11 are forced upwardly with the curved outer surface 28 bearing on and against the member into which the staple is driven and forming a fulcrum surface therefor, so thatthe staple is easily and quickly pulled with a minimum of effort. The formation and construction of the staple pullerlis such that a staple can be readily engaged and pulled thereby, irrespective of the position or condition thereof in and on a member in which driven. a V r When it is desired to employ theim;

plement asa hammer, the spring locking,

clip 33 is swung over onto head until 7 desired long lever or swinging action in using the hammer. In hammer formingposition the inner side of the handle portion32 of arm 11 is opposite the reduced or thin portion of arm 10, so that the hand fits readily aroundthese opposite portions with the fingers disposed under and through thehandle 32. I I

The staple puller is of considerable utility in fence erection and repair work, as a bucket or similar handled receptacle can be supplied with staples and attached to hook and readily transported with the implement as a handle to the point of operation. -Then with the staple puller and hammer, together with the wire cutter formed by blade 40, the necessary tools are always at hand for the desired work. The staple puller is preferably formed of a suitable metal and because of the simplicity of its construction will be durable and withstand the usage to which put.

It is alsoevident that various changes,

,modifications, variations, and substitutions might be resorted to without departing from the spirit and scope of my invention, and hence I do not'desire to limit myself to the exact and specific disclosures thereof.

Desiring to protect my invention in the broadest manner legally possible, what I claim and desire to secure by Letters Patent i of the United States, is: i

1. In a staple puller, parallel members pivoted together at one end for swinging movement toward and from each other, one of said members formed at its free end with a staple engaging head, and the other of said members formed at its free end with a hammer head for striking said engaging head when the members are swung together, and locking mechanism for detachably securing said members in position swung together with said heads alined to form a hammer head, said members providing a handle therefor.

2. In a staple puller, substantially parallel substantially members pivoted together at one end for swinging movement toward and from each alinement with and striking said engaging head with the members swung together, the staple engaging head member formed with a widened linger grasping portion adjacent said head, and the hammer head member formed with a handle portion adjacent the pivoted end thereof.

3. In a staple puller, s1 fiantially parallel members pivotally joined at one end, one of said members provided with a transversely disposed staple engaging head at its free end, and the other of said members provided with a transversely disposed hammer head at its free end for alinement with and striking said engaging head with the members swung together, said heads in alined engaged position spacing said members apart, cutting blade disposed longitudinally of one of said members on the inner side adjacent the pivoted end thereof, and the inner side of the other member opposite said blade formed to provide a base for receiving a wire to be severed by said blade when the members are swung together.

l. In a staple puller, substantially parallel lever members pivotally connected together at adjacent ends for swinging movement toward and from each other, a transverselydisposed staple engaging head on theiree end of one of said members, said head extended outwardly from said-members and curved inwardly toward and longitudinally thereof and pointed at its outer end, the outer longitudinal side oi said head forming a curved fulcrum bearing surface,-

a transversely disposed hammer head at the free end 01' the other of said members positioned to strike and aline with the staple engaging head when the members are swung together, and a lock carried by one of said heads for detachably engaging the opposite head to secure the heads and members in position swung together to form a hammer head and handle therefor.

In testimony whereof I have hereunto set my hand at Kane, Pennsylvania, this 6th day of April, 1925.

JOHN AARON PETERSON.
