HOSE-CLAMP APPLIER.

Specification of Letters Patent.

Patented April 27, 1909.

Application fi led November 30, 1908, Serial No. 465,111.

To all whom it may. concern:

Be it known that L-VVILLIAM O. STEIN, a citizen of the United States, residing at Pottsville, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in' Hose- Clamp Appliers, of which the following is a specification.

Myinvention relates to an improved hose clamp applier, adapted to hold a wire clamp in position on a hose, which can be operated to tighten the clamp to any desiredextent, and which can then be operated to bend the. wire, and secure the clamp against move- VVith these and other objects in view the invention consists in certainnovel features of construction, and combinations and ar rangements of. parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1, is a perspective view illustrating theapplication of my improvement. Fig. 2, isa frag- Fig. 3, is an end view. Figs. 4, 5 and 6, arelper spective views of variousdetails of construction, and Fig. 7, is a view of the wire hose clamp. j 1 My improvements comprise in the main, two members or handles 1 and 2 respectively. The member 1, at one end, extendsatright shown at 3, and again extends at right angles forming a clamping jaw 4. The member 1 at the portion 3 is made with a slot 5, through which the handle portion of member2 proj ects, and a pin 6 is passed through the members to pivotally secure them together. The member 2 atits end is made with a clam ing jaw 7 to cooperate with the jaw 4 and securely clamp wires between them, as. will hereinafter appear. i

Member 1 is made with a dove-tail recess 8, of general wedge-shape, into which the wedge-shaped steel cutterblade 9'is driven and firmly secured. This cutter blade 9 is made with an o ening 10 to receive the wire 1 to be cut, and tl fe cutter. blade is close beside the side face of member 2, so'a's to give a shear out, when the wire is in position in the opening 10, and the member, 2 is moved toward the member 1 to neatly severthe wire.

The member 1 is made. with an elongated recess 11 having a shoulder 12 at one end of the recess and a lug 13 at the other end. This lug 13 is made with a screw threaded opening to receive a screw 14 having a milled enlargement 15 on its outer end. A block 16 is swiveled to the end of the screw and is grooved on its inner face to slide on member 1, and prevent anyrotary movement of the block. The block is moved by its screw toward or away ,from the shoulder 12, and is adapted to clamp a wire against said shoulder. The block is of the proper width, so that when a wire is clamped between it and shoulder 12, and the ends of thewire bent at right angles against the block, the wire will be in the proper shape and of the proper size to form a hose clamp such as shown in Fig. 7, which can be perfectly clam ed by my improvements, which will now be described.

The jaw 4 is made with. a longitudinal opening extending entirely through the same, and of a shape in cross section to conform to the outline of a plunger 17. The

plunger 17is flat on its upper face and is provided with a transverse groove or notch 18 in its end, and the end is then grooved slightly as shown at 18 to conform to the curvature of the end of jaw 4. This curvature permits the tight engagement of the jaw against the curve of a hose.

The inner end of plunger 17 is provided with a long screw which projects rearward from the j aw. A bracket 19 having dovetailed flanges 20, to dove-tail into similarly shaped grooves in the member 1, is secured to said member at therear end of jaw 4, and

a hand wheel 21 is provided with a hub extension22 swiveled into this bracket 19 to permit rotary movement of the hand wheel and prevent any. longitudinal movement thereof. The hand wheel 21 is internally screw threaded to mesh with the screw threads of the plunger, so that when the wheel is turned, the plunger will be either projected or drawn inwardly as the case .may be. i

r The operation of my improvements is as follows: The wire is cut into the desired lengths by means of the cutter 9. The wire is then placed between the block ,16 and shoulder 12 and is securely clamped. The endsof the wire are then bent at right angles against the outer face of block 16 to form a hose clamp as shown in Fig.7. The ends of the wire are then passed around the hose as shown clearly in Fig. 1, and are projected through the intermediate bent portion 23 of the Wire as is ordinarily done. The ends of the wire are then securely clamped between the jaws 7 and 4., while the plunger 17 is positioned with its grooved end 18 engaging the portion 23 of the wire clamp. While the ends of the wire are securely held by the jaws, the hand wheel 21 is turned to project the plunger 17 which, by reason of its engagement with the portion 23 of the wire clamp will cause the ends of the wire to be drawn tightly through this portion 23 and securely clamp around the hose. When the desired tension is secured the tool with the end of plunger 17 as a fulcrum on the portion 23, is thrown backward across the hose to bend the ends of the wires down upon themselves, and over the portion 23 to securely tie the clamp. The ends of the wire can then be cut off in any desired manner.

Slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention Having thus described my invention what Iclaim as new and desire to secure by Letters Patent is:

1. A tool of the character described, comprising two members, one member crossing the other and pivotally secured thereto, a clamping j a. fixed to each member and movable therewith to clamp a wire between them, and one of said jaws having an opening extending through the same, and a longitudinally movable plunger in said opening and supported solely by said jaw.

2. A tool of the character described, comprising two members, one member crossing the other and pivotally secured thereto, a clamping j aw fixed to each member and movable therewith to clamp a wire between them, and one of said jaws having an opening extending through the same, a longitudinally movable plunger in said opening, and a hand. wheel on the inner end of said plunger constructed to move the same longitudinally.

3. A tool of the character described, c0mprising two members, one member crossing the other and pivotally secured thereto, and carrying fixed clamping jaws at one end, one of said clamping jaws having an opening extending through the same, a longitudinally movable plunger in said opening having a screw threaded inner end, a bracket lixed on said jaw, and a hand wheel swiveled in said bracket and having internal screw threads meshing with the screw threads of the plunger.

4. A tool of the character described, comprising two members one member crossing the other and pivotally secured thereto, and having clamping jaws at one end, one of said jaws having a longitudinal o ')ening, one wall of said opening being flat, a longitudinally movable plunger in said opening having one face fiat, screw threads on the rounded inner portion of said plunger, and a hand. wheel having screw threads meshing with the threads of the plunger, and constructed to move the same longitudinally.

5. A tool of the character described, comprising two members, one member crossing the other and pivotally secured thereto, and having clamping jaws at one end, one of said jaws having a longitudinal opening, one wall of said opening being flat, a longitudinally movable plunger in said opening having one face flat, screw threads on the rounded inner portion of said plunger, a hand wheel having screw threads meshing with the threads ol the plunger, and constructed to move the same longitudinally, and a bracket fixed to said plunger carrying jaw, and in which said hand wheel is swiveled.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
