F. W. GUNN. HOSE CLAMPING TOOL.

- UNITED. .s A Es ATE T OF E- FRED wILtIs-"eUNN oF DEDHAM, 'MASSAGHUSETTSQ i 1 I-IOSE-CLAMPING TOOL; v

To all whom it may concern." v vBe it known that I, FRED WILLIS- GUNN, a citizen of the United States of .America, residing at Dedhain, in the county of Norfolk andState of Massachusetts, have invented ;new and useful Improvements in" Hose-Clamping Tools, of which the following is a specification. I

This invention relates to tools for applying clamping wires or hands to hose or like flexible tubes for clamping and securing the same to pipes, nozzles, nipples, couplings,

- and the like. 1 A principal object 'ofthe'invention isto provide a simple and easily op- .erated tool thatis adapted to draw up a clamping wire tightly around the hose and then to sever it leaving a proper length of v,the wire endsprojecting .in most advantageous position for bending back to make the clamp secure. A further object is'to providea-tool of the kind described equipped with means for severing and removing easily extremities of the wire that are caught in the device after an operative. -movement thereof. still further objectis to provide a wire clamping toolequipped with an op erating element that-is in one. position adapted to cooperate withthe wire for the drawing up thereof-to leave ends'projecting at the required angle, and in'another position adapted to serve as a cuttin'g ofi instrumentality for removing extremities'of the wire.

The foregoingfandj other objects and "advantages of the invention will more fully appear .from the following detailed ;descrip- .tion, andthe distinctive features of'novelty will thereafter be nendediclaims; 3 7

Adjacent one op-' erative. endis pivoted at ll ajtransverselyextending block or slab-12 havinglonef'end thereof relieved as indicated at 12 to constitute-a. cutting edge] Through this slab a short distance to oneside of-the pivot 11 toward the end bearing thelcutting edge, a hole .13 is formed through which the clamp wires are adapted to be passed. ,A stout pin"14 is mounted toturn in the b0dy'10 parallel .'with the pivot 11 and spaced some little distance tothe rear thereof. This pin has a-s'quared or angular head 14 atone endthereof adapted to receive a wrench or like operatingftool};

and its other end is fitted with a cotter pin- 14", tolhold the same: from casualdisplace nent., This .pin has a:'hole 14 throughith'e intermediate portion thereof and through In use a pipe or nippleP. with the hose thereon ready .for clamping is provided a clamp wire W which as usual is doubled in termediate its length atW and has its end 75 I which the wires tare adapted tolbe'pa ssed.

portions'passed through. this double orloop to be drawnfup and bent backwas indicated at B for holdingthe clamp in position, In

accordance with my invention, the extremities .W of the wire after bein'g I passed throughtheloop W are passedth-rough the.

hole 13 of the slab 12: and thence through the h0le14of the pith-I114 Therlipon on wrench or handle-inla direction to thefleft .turning jthe pin 14 meansof a 'suitable or reverse clockwise, theL-wires aredrawn up taut so as to clamp the hose 'closelyfand securely to, the pipe and in this. drawing up operation the wire will-be bent. at alsmall angle on the corner 13* .ofthe hole 13.," this they are drawn up to the requisite degree of tautness for clamping, with the wire ex tremities thus left projecting outward from the loop W, adapted to hold the hose clamped and in readiness to be pressed back or hammered down as indicated at Bto com-' plete the clamp. Upon the severing of the wires at the point 13 the extremities thereof will be Wound around the pin 14 to a greater or less extent as well as'being passed throughv the hole 14. These extremities of the wires may now be quickly and easily freed from the pin 14 by swinging the slab 12 so that its cutting edge 12? moves downward to engage the pin 14: as indicated in Fig. 4, it

' being noted that the dimension of said slab is correctly proportioned for this purpose.

'The eupo ont ning t e pi to th ight or in a clockwise direction as seen in Fig. 4, the wire ends are severed directly over the hole ll and'are thus disengaged from the pin. I preferably form the other end of the Ody or holder 10 with convex edges 10 similar to the edges 10 and ivot adjacent this end atll" a slab 12 having a hole' 13,

the purpose of this being to permit a hose to be engag'edwith this end of the device for applying the clamping wire in cases where the projecting ends of the wires are of greater length. i In this case the'wires will be passed 'throughthe hole' 13' and thence through the hole 14 of the pin andthedeviceo erated otherwise'as already described.

7 I am'aware that the'invention maybe embodied inother specific forms without departing from ,the spirit or essential attriutes thereof, and I therefore desire the present embodiment to be considered in all "respects as. illustrative and not restrictive, reference being had to the appended claims rather than-to the foregoing description to indicate the'scope of the invention,

Having described my, invention whatI claimas'new and desire to secure Let- 'ters Patent is: 35

1. .A .hos e clamping tool, comprising a in substantial parallelism with the" pivotal axis of said member spaced from the operaitive 'end' thereofiand adapted ,to engage the extremities of wire for draw ng the am e t- 2. A hose clamping tool, comprising a holderhaving' a slabfpivoted transversely r therein 'adjac'ent one end'thereof, said slab hav g. a e req ng' P s g efthrough and having one end thereof formed to serve as a cutter, and a ,turning pin e 'ntel in said he derfb s of sai S in presence of'tw'o witnesses;

adapted to engage the wire extremities, to draw the same through the passage of said slab and cause severance thereof against an edge of the wire receiving passage of said slab, the cutter end of said slab being then adapted to serve as a means ,for removing the severed ends.

3. A hose clamplng tool, comprising a 7 body constituting a holder having transversely pivoted adjacent one end thereof a slab vwith a wire receiving passage therethrough at one side of said pivot and having one end thereof formed with a cutting edge,

and a turning pin mounted in said holder back of said slab with a passage} thercthroughto receive the wire extremities,-said pin equipped, with means for turning the same to draw up the wire and 'finally'qause severance thereof byenga'gement with an edge of the wlre receiv ng passage of sa d slab, said pin being in position'for co-action with the cutting edge "of said slab to sever and remove the detached wire ends.

4. A hose clamping tool, comprising a body constituting a holder withslabs trans- 1 versely pivoted adjacenteach end thereof, each of 'said slabs having a wire receiving passage therethrough at one side of its pivot,and a turning pin mounted intermediate'the length of saidholder adapted to draw up wire extremities from either end "of'said holder when projected] through ither of said slab passages.

5. A hose clamping tool, comprising a body constituting a holder with slabs transversely pivoted, adjacent each end'thereof each of said slabs having a wire receiving passage therethrough at one side 'of its pivot, and a turning'pin mounted intermediatethe, length of said holder adapted to draw up wire extremities from either end of said holder when -'projected through either of'said slab passages, one of said slabs having an end thereof formed as a cut- I ting edge and adapted to cooperate with 7 said pin for severing and removing detached wire ends.

' In testimony whereof I afiix my signature FRED WILLIS GUNN.
