CHARLES H. HERTH, OF MEMPHIS, TENNESSEE, ASSIGNOR TO BALING TIE BUCKLE COMPANY,

OF MEMPHIS, TENNESSEE.

WIRE-PULLER.

Specification of Letters Patent.

Patented Nov. 10, 1908.

T0 all whom 'it may concern:

Be it known that I, CHARLES H. HERTH, a citizen of the United States, residing at Memphis, in the county of Shelby and State 'of Tennessee, have invented a new and useful Wire-Puller, of which the following is a specification.

This invention relates to improvements in particularly to the kind used in drawing Wire around bales, packages, cases and the like.

One object of the present invention is to provide a hand device that Will freely move over the Wire when moved in one direction, and by a reverse movement automatically clutch or grip the same.

Another object is to construct a device the mechanism of which will tend to increase the grip on the Wire during the operation of pulling the latter taut around a bale or the like.

Another object is to provide a device simple in construction and embodying comparatively few parts.

With these and other objects in view as Will more fully hereinafter appear the present invention consists in certain novel details of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims it being understood that various changes in the form, proportion, size and minor details of the device may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings -Figure 1 is a longitudinal seetional view showing the gripping mechanism. Fig. 2 is a similar view taken on line 2-2 Fig. 1. Fig. 3 is a detached perspectve view of the gripping mechanisrn. Fig. 4 is a similar view of the cap. Fig. 5 is a perspective of the retaining collar. Fig. 6 is a similar view of the pusher, and Fig. 7 is a perspective of the spring for actuating the pusher.

Similar numerals are employed to designate the corresponding parts throughout.

In the construction illustrated in Figs. 1 and 2 a handle 1 preferably formed of Wood or other suitable material and of the usual shape is centrally provided with a longitudinal bore 2 extending from the lower or smaller end 2a, and terminating at the upper or larger end 3a. On the lower end 2a a ferrule 3 of an interior diameter adapted to snugly fit over the end 2CL is provided, and on the lower or bottom end of the ferrule is a projection 4, of an exterior diameter considerably less than said ferrule. The projection is centrally provided With a longitudinal bore in direct alinement With the bore 2 of the handle and terminating in outwardly inclined walls 5 forming a bore of a greater diameter than the bore of the handle.

Adjacent the opposite or larger end 3a of the handle a transverse recess 6 is formed the function of which Will presently appear. The upper face 3a is countersunk forming a central circular seat flanked by the shoulder 7. A circular pedestal or support 8 of an eX- terior diameter somewhat less than the end 8CL of the handle is provided with a reduced portion 9 adapted to snugly fit Within the seat formed in the upper end of the handle. The support is centrally provided With a bore alining with the bore 2 of the handle. The support is secured in the seat by means of bolts or screws 10 entering alining perforations formed in the support and handle on either side of the bore 2 and terminating in the transverse recess 6 into which nuts 11 are inserted for the ends of the screws 10. On

the lupper face of the support 8 are two cheeks 12 preferably formed integral with the support and projecting at right angles to the upper or outer face thereof. The cheeks extend transversely of the support and are disposed on either side of the central bore 2. Mounted between the cheeks 12 on pivots 15 and 16 disposed adjacent the opposed ends of said cheeks is a pair of gripping members 13 and 14 having enlarged heads each provided with a cam surface the greater portion of which is serrated as shown at 17 and terminating in reduced handle portions 18 and 19, intermediately bent at substantially obtuse angles and forming finger pieces 20 and 21. It is to be observed that the openings in the heads 18 and 111 are a trifie to one side of the longitudinal center so that the finger pieces will normally lie parallel to the handle 1.

A collar 22, of an exterior diameter equal to that of the hanclle l and an interior diameter considerably greater than the exterior of the support 8 is provided With a pair of diametrically opposite recesses 23 which receive the handles 18 and 19.

A cap 24 of an eXterior diameter equal to that of the collar 22 is provided with a reduced portion 25 of sliglitly less exterior diameter than the interior of the collar 22, and is adapted to be inserted between tlie inner face of said collar and exterior `of the support 8, as clearly shown in Figs. 1 and 2. The head 26 of the cap is provided with a bore alining with but of greater diameter than the bore 2 and is further provided with a pair of longitudinal recesses extending inwardly from the lower end, and adapted to register with the recesses 23 formed in the collar 22. The head 26 of the cap lies considerably beyond the upper edges of the cheek plates 12 forming a chamber for the reception of the grip actuating mechanism, which is shown in the present instance to consist of a pusher preferably formed of a inetallic disk 27 adapted to slidingly fit within the cap 211 and centrally provided 011 one face with a nipple 28 adapted to slidingly fit into the opening formed in the head 26 of the cap.

A helical spring' 29 is adapted to encircle the nipple 28 its terminals resting on the inner face of the head 26 of the cap and disk 27.

Vhen assembling the parts, the support 8 is first secured to the handle by means of the screws 10 thus retaining the grippers in the position shown in F ig. 3. The pusher 27 and spring 29 are then inserted in the cap 24 and the reduced end of the latter forced between the collar and support. This action will bring the pusher in contact with the heads 13 and 1A of the grippers forcing the latter into the space between the cheeks 12 to a position approximately fiush with the upper edges of said cheeks. The pa'rts are then secured in place by means of screws 30 enter-. ing registering openings formed adjacentA the lower edge of the collar 22 cap 25 and support 8 as clearly shown in Fig. 2.

In order to prepare the device for use, the finger pieces 20 and 21 are squeezed inwardly by the fingers of one hand. This movement widens the distance between the serrated faces of the heads 18 and let and at the same time raises the pusher 27 against the action of the spring 29 and forces the end of the nipple 28 farther out- Ward. The free end of the wire 31, to be used is now inserted through the bore of the nipple thence down between the serrated faces of the grippers, into the bore 2 and out the lower end 5, the pressure on the finger pieces is then released and as the latter are moved outwardly by the force of the spring 29 through the pusher 27, the

serrated faces engage the wire 31. It is obvious when the parts are in this position and that part of the wire beyond the end 5 in position to be pulled taut around a bale or the like a pull on the handle 1 in the direction indicated by the arrow in Fig. 1

of the drawing will cause the serrated faces of the grippers to move inwardly thereby increasing their hold upon the wire, this they will continue to do as the pull on the wire ncreases.
