A'still further important object of'this -invention is to provide a tool ofthis class which is 2 while either againgripping' the, strap for anotherbite or :Eurthentake-up operation orior fastening or securingthefree-end of thestrap to the buckle.

It is'a further important object of this inventionto providenovel'a'nd simple means for gripping-the endofthe strap or-bandto be dr'awnor tightened with respect'to the buckle; and also simple and effectivemeans'fordrawing such end quickly and also with considerable force, and further to provide such means in a compact sliding "member" and in combination with means for cutting the strapor-band.

An important object also of. this invention is to provide a novel combinationota strap, buckle therefor, and a tool for-holding-the buckle and tightening and fastening the strap with respect to the buckle, I

An important modification of my invention is to providea tool of this class which maybe readily placed astride astrap and buckle from the side ofthestrap and particularly when theloose end of" the strapextends a considerable distance beyond the buckle, orwhenthe strap is uncut.

With these and other objects in view, as will appear hereinafter; I have devised a strap fastening tool, and combination thereof with a buckle and strap, having certain novel features of construction and arrangement ofparts and portions, as will-behereinafterdescribed in detailand particularly set forth in the appended claims, reference being had to the accompanying drawings, and to the characters of reference thereon, which form a part of this application; in which:

' One form of strap fastening means with which the tool of my present invention is adapted tobe used is that shown in my co-pending application, Serial No. 537,407, filed May 26, 1944, now issued as Patent No. 2,533,275, dated December 12, 1950. This strap fastening means consists of a buckle A and a strap or band B, one end designated B of the latter being fastened to the buckle, the intermediate portion thereof,-designated B be ing looped around the object or article to be latter clamped or bound by the strap, and the freeend B thereof being adapted to-be-threaded and drawn throughthe buckle, tightly around the article to be clampedor bound, and bent over or fastened to the buckle after being so drawn tightly around the object or article. I

The essential parts of my invention consist of a head C and a movable member D, the latter containing the take-up jaw means, cutter, and the-like.

The head C consists of a head member I which is bifurcated at its forward end providing furcations I These furcations have transverse recesses I at their undersides and near their-forward end, these recesses forming pockets I at the rear edges of the recesses I fo receiving one edge of the buckle A. The normally outer side or outer plate portion of the buckle engages the bottom of the recess l The other or forward edge of the buckle is engaged by a movable jaw 2 provided adjacent the lower and rear sides of a slide 2 which is reciprocally mounted on ways I at the adjacent sides of the furcations I The slide is held in position by an angular retaining plate 3 extending between and over the outer ends of the furcations of the head member I.

The slide 2 is moved backwardly into buckleengaging position by means of an eccentric 4 which is carried on a pin 5, this pin being rotatably mounted between the furcations I The eccentric is positioned in vertically elongated slots is secured in position by a screw W.

4 2 in the end or leg portions 2 of the slide, which is U-shaped, the leg portions being mounted on the ways I At one end of the pin 5 is provided a lever 6 which, when shifted from the position shown in Fig. 5 to the position shown in Fig. 6, is adapted to move the slide 2 to the buckle engaging position shown in Fig. 6.

From this buckle, the end B of the strap B may extend under the tool, thence around the article or object tobe clamped, and is then threaded with its other end B through the normally forward edge of the buckle.

On the eccentric 4 is pivotally mounted a dog I which is provided at its free ends with teeth I which are adapted to engage the upper side of the end B of the strap, and clamp the strap against the buckle or against the end B of the strap. The free end of the dog is adapted to extend between clamping ears A of the buckle A. On the hub portion of the dog is provided a slot l in which is .locateda stop in the form of a screw 3, which is secured to the eccentric 4. This slot 1*? permits limited movement of the dog about the eccentric, the screw 8 limiting such pivotal movement. As the lever B is shifted to the position shown inFig. 6, the dog 1 is forced against the strap B and locked in position by the eccentric. Thus, the strap may be simultaneously held in position with the clamping of the buckle by the head,.but the dog alone may be loosened slightly to, permit the strap to be drawn freely through the buckle.

Intermediate the forward and rear ends of the head member I are provided spaced shoulders I into which are screwed guide rods I I, these gui' c rods extending backwardly and upwardly, the rear ends of the guide rods being positioned considerably abovethe plane of the base of the head member. The rear ends of the guide rods are secured relativeto each other by means of an end member I2, thesamebeing secured to the rods by screws I3.

On the guide rods is slidably mounted an operating or jaw carrying slide I4. This slide has a slot I4gextending from the front to the rear end and open; at one side, as-shown best in Figs. '7, 8, and 10. ,The free end B? of the strap is adapted to extend backwardly through this slot. The slide I4 is provided in the rear portion with a recess I 4 'in which is positioned a jaw support l5, which This support I5 carries a-dog I6. The dog is pivotally mounted at its forward end on the support I5, and has anotched free end IIi which extends into. the slot I4 from the upper side thereof, the

free end of the dog being forced into said slot by a spring l1. Thus, the free end B of the strap is automatically secured within the slot M when placed therein.

In order to permitextreme forward movement of the slide I4 the head member is undercut at I backwardly from the faces I this undercut portion or depression I extending to near the bottom of the member I. The bottom of the depression may be inclined at the angle of the guide rods I I. This construction permits the slide I4 to be shifted so that-the forward end may engage the faces I Theoperatingor jaw carrying slide I4 is moved or drawn backwardly on the guide rods I I in order to draw the free end of the strap through the buckle and tightly around the object or articleto, be tied-or clamped. One means for drawing the slide I4 backwardly consists of a lever 2| and a link 22, the former of which is detachablymounted with..-one. end one rotating pivot :23u1ocated at ,oneside of theend member I 2. The intermediate portion of theleverl 21 ,is pivotally connected .by the link 22 to the side of 'therslide, I4. .Thus, whenthe freeendorthe leverrZI is drawnbackwardly, the ,slideismoved backwardly onthaguide rods l I.

This method, of moving vbackwardly theslide l 4 and of taking ,up the slack .in the strap .B, from the end.B ,.thereof,. may.take.up as much. asthree or four inches. or more, of the; length ,of .the strap during onestroke of themleverz I. ."Ifhis,c,onstruction and method of operation is :sufiicient for box.,strapping or .bale.tying. jIt isuobvious, however,. that great tension cannotbe. exerted on the strap B hythis method, such as is ormay berequired. in hose clampi g, and thelike, except for ,theinitialtake-up.

The; sli de M maybe moved forwardly for such purpose by either the lever 2| and link 22, or by means of the screw 3|.

;In the modified construction of the head,'shown in Fig. 13, .the head is openat one side a to I permitalong free end or portion 3 10f the strap, which isalready threaded through the buckle, or .an-end which is threaded through-the buckle wound vorra-rolLto-be inserted into the head from theqside, so-thatit may be secured to the jaw means carried by the slide M, In this modified structure, the head is preferably made of two or three members, the drawing showing three separate-members,namely,-a main head member 6!, forming'themain support-andone side, a side memberrfiz forming the opposite side, and a cantilever member :63, which maybesecured to the endsof the vmembers -BI and .62 by screws 64. The slide-J is'slidably mounted between the-members afil hand "-62, gas in the -.,former construction. One guide :rod H extends backwardly froma shoulderifil of thermember GI and the other rod froth-a,correspondingshoulder of the. member 62. .-A. spaeeor passage E isprovided between the rear-end of I the-side member 62, andv the adjacent portion of the-member BLwhereby: the portion of the strap, secured'to ,the buck1e,1may be readily placed. in alignment .With .the, jaw ,means of the slide.

rBefore vsecuring vthe strap fastener around, a hose, box, or the like, one end ,of the strap or band B is secured to the buckle A. "Thebuckle A is then inserted in the recess I of the head member I and secured or locked therein by moving the slide 2, thereby'clamping the buckle between the fixed jaw I of the movable jaw 2 The strap or band is then drawn around the object to be clamped with the band extending backwardly underneath the tool and around the object. The free end B of the band or strap is then drawn through the front end of the tool and threaded through the buckle, immediately over the end B secured to the buckle, and below the upper fold of the buckle between the clamping ears A The extended end of the band or strap is then threaded through the horizontal slot l4 of the slide M. This may be done by inserting the portion B into the side of the slot. The pawl I6 rests upon the portion B of the strap or band, and when the slide I 4 is drawn backwardly by either the lever 2| and link 22, or by means of the screw 3 I, the band or strap is drawn through the buckle tightly around the object to be clamped. The pawl 1 on the slide 2 resting upon the portion B of the strap automatically grips and retains the free end of the strap in the aforementioned position and holds the same while the slide [4 is moved forwardly for another bite upon the strap in order more tightly'to draw it around the object. When the strap is drawn sufficiently tight, it may be cut by the cutter 4|. The slide [4 is then drawn backwardly while the die 5| is forced forwardly. The slide 14 is then moved forwardly into engagement with the die'5l which causes the end B of the strap to be folded over the buckle between the ears A of the buckle, the forward downwardly and rearwardly inclined edge of the die engaging underneath the end of the strap and, in forward movement of the die over the upper surface of the buckle, folding the strap end over the buckle and between the ears. The forward or lateral portion of the die defined by the curved recess therein serve to engage the ears of the buckle to produce at least a partial inward folding of the ears. The die is then returned to its rear position and the buckle with the strap end bent thereover is released by moving slide 2 forwardly and thereby opening jaws I and 2 Though I have shown and described a particular construction, combination, and arrangement of parts and portions, and a certain modification thereof, I do not wish to be limited to the same, but desire to include in the scope of my invention the construction, combination, and arrangement substantially as set forth in the appended claims.
