Application filed April 12,

The present invention relates to improvements in wire tighteners and has for its principal object to provide an implement which may be readily and efficiently used for tightening a wire around a hose, barrel, boX or the like.

()ne of the important objects of the pres ent invention is to provide a wire tightener which is simple in construction, inexpensive, strong and durable and further well adapted to the purpose for which it is designed.

@ther objects and advantages of this invention will become apparent during the course of the following description talren in connection with the accompanying drawing.

In the accompanying drawing forming a part of this application and in which like nume 'als designate like parts throughout the same:

Figure 1 is a side elevation of the wire tightener embodying my invention, parts being broken away and showing the implement in use.

Figure 2 is an edge elevation of the swivel head and the internally threaded sleeve member showing the same associated with the threaded shaft, and

Figure 3 is a fragmentary detail showing the connection between the upper end of the threaded shaft and the head member. 7

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 dcsignates generally my improved wire tightener, the same comprising the screw threaded shaft 2. A head 3 is swivelly supported on the upper end of the screw threaded shaft as in dicatcd at 4; with reference more particular to Figure 3 of the drawing. This head 3 tapers gradually toward its upper end as is clearly illustrated in the several figures in the drawing. A pair of upstanding projections or lugs 5 are formed on the upper end of the bloclr 3 by cutting away the intermediate portion 6 thereof. A channel or groove 7 is formed in each of the side edges of the block, and the projections 5 are formed also with the channels or grooves 8 for a purpose to be hereinafter more fully described.

A block 9 is provided with the sleeve 10 on the bottom thereof and this sleeve is internally threaded as is also the central opening formed in the block 9 to accommodate the screw threaded shaft 12 whereby the block is adapted for movement along the threaded shaft in the manner to be presently apparent.

1926. Serial No. 101,415.'

A vertical opening 11 is formed in each end portion of the bloclr 9 as clearly illustrated in Figure 1.

lln actuating handle 12 is secured on the lower end of the threaded shaft 2 in any suitable manner.

The use of my improved wire tightener may be briefly stated as follows:

The wire looped around the object which may be a hose, barrel, or the like, and the ends of the wire are crossed and then disposed in the groove 8 in the projections 5 formed on the upper end of the block 3, the ends of the wire being then bent downwardly and disposed within the side grooves or channels 7, the free ends of the wire are then passed through the vertical openings 11 provided therefor in the end portions of the block 9 and the free ends of the wire are then twisted or otherwise secured together as clearly shown in Figure 1.

The upper end of the head will be in en gagement with the object around which the wire isto be looped or tightened, and it is obvious that when the handle 12 is turned in one direction, the member 9 will be caused to travel downwardly on the screw threaded shaft 2 thus causing the wire A to be tightened around the object in the proper clamping position. After the wire has been stretched and properly drawn taut around the object, the implement comprising my improved wire stretcher is removed and the free ends of the wire are secured in the usual manner, l Vhen wire nails, or hoolcs are employed in connection with a barrel, it is to be understood of course that the usual staples are driven into the barrel stavos, and support the wire around the barrel in a properly clamped position.

The simplicity in which my improved implement is constructed enables the same to be readily and easily operated and will at all times be positive and e'liicient in carrying out the purposes for which it is designed.

While I have shown the preferred embodiment of the invention it is to be understood that minor changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit of the inven tion and the scope of the appended claim.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is A wire structure of the class described comprising a threaded shaft, a tapered head swivelly supported on one end of the shaft, an actuating handle secured on the opposite end of the shaft, a pair of end lugs formed on the smaller end of the head, the tapering -Sides of said head having guide grooves formed therein, sald lugs having guide grooves formed in the ends thereof and merging into the first mentioned guide grooves for the reception of the free ends of the Wire which is to be stretched and clamped, a block threaded on the shaft, said block being provided with openings on diametrically opposite sides of the shaft through which the free ends of the wire are adapted to extend and then bent to prevent the displacement of the same with the said block, the axes of the openings being in parallelism with the axis of the shaft the distance between the openings being equal to the distance between the adjacent ends of the guide grooves on the head, said block being adapted to move along the shaft upon rotation of the shaft for tightening the wire when the handle is turned in one direction.

In testimony whereof I afiix my signature.

HOMER H. HULL.
