SPECIFICATION forming part of Letters Patent No. 492,855, dated March '7, 1893.

Application filed December 9,

1891. Serial No. 414,478. (No model.)

Syracuse, in the county of Onondaga,

ful Improvements in exact description.

My invention relates to hose clamps by which a hose is secured upon a nipple or pipe.

My object is to construct a clamp from a single piece of wire, which will completely its free end will also it, and is provided with a loop or eye through which the fastening bolt or and which operates to tighten said clamp by drawing said free ends toward forcing them apart or away from each other, in either case tightening the size of the circle, wind or coil around, embedding it into the hose; and in either construction the piece of wire itself to form an ob-. long loop of wire, and the ends of the wire itself, are secured together, the ends of said loop forming and being the loops or eyes encircle the hose, and partially encircle screw is passed,

each other, or by clamp by reducing the is primarily bentupon through which the bolt or screw isinserted.

My invention consists in forth in the claim hereunto annexed.

to the accompanying drawings, in which complete. Fig. 2, is a top 3, is a plan view of the plan thereof.

securing the ends of 4, is a top plan body, in which the wire together.

that the screw operates to from each other, and in which the coil upon one end of said loop forms the nut which rethe opposite end simply forms a socket to receive the point ceives the screw, and that upon WEIDAW, of in the State of New York, have invented new and use- Hose-Olamps, of which the following, taken in connection with the accompanying drawings, is a full, clear, and

the several novel features of contruction and operation hereinafter described and which arespecifically set It is constructed as follows, reference being had end of said screw and in which it rotates. Fig. 5, is a sectional elevation of Fig. 4, on line w, 00, therein. showing the same construction as in Figs. 4 and 5, except that itis tightened'by drawing the eyes toward each other.

A, is the clamp constructed by first bending a wire to form loops or eyes 1 and -3 at the ends, and securing the ends of the wire together to form the intermediate clamp body -2-, composed of two strands, the same being divergin so wider than the other. Ihis looped clamp body is then bent centrally to form a circle, the end carrying the loop or eye 1 being passed through said crossed, or the eye -1- again tucked through the body adjacent to the eye -3 so as to bring said eyes in opposite relations to those shown inFigs. 1 and 2, In either case, the eyes themselves are bent so as to stand at an angle as shown. InFigs. 1 and 2 said eyes are adapted to receive an ordinary bolt and nut; but in Figs. 4' and 5 the eye -3 consists of a coil formed transverse to the body of the clamp, coiled tightly, so that the convolutions form, in themselves, the threads which engage with the coarsely threaded screw.

In Figs. 1, 2 and 6, the clamp is tightened by drawing the eyes -1- and -3 inwardly or toward each other; and in Figs. 4 and 5 it is tightened by forcing them apart, or away from each other. In either case, the complete circle first made, by bending the body, creates two strands of wire around the hose, and the remainder of the bending creates two other strands extending nearly around it in Figs. 1, 2 and 6; and-clear around it in Figs. 4 and 5, so that in the latterthere are four strands around it all of which are tightened simultaneously.

What I claim as my invention, and desire to secure by Letters Patent, is-

A hose clamp, comprising a wire, form a looped body, ends formed by coiling bent to and eyes at its extreme the wire, the sides of said body diverging from the eyes toward body,and the free ends of the loop are brought up either contiguous to each other as shown in Figs. 1 and 2,0rare Fig. 6,is a side elevation that one end is each other, and adapted to be wrapped clear In witness whereof I have hereunto set my around the hose, one end being passed through hand this 12th day of November, 1891. the body in wrapping it about the hose, said eyes being bent outward, substantially par- WEIDAWf In presence of HOWARD P. DIMsoN, HERBERT A. CARHART.

5 ailel to each other, and a bolt inserted through said eyes and means for securing it, as set forth.
