The latter of said patents-na mely, No. 653,337discloses a very simple and effective type of bale-band fastener, essentially consisting of a rotatable buckle. So for illustrative purposes, to show the action and function of the tool, this type of fastenerisindicatedin the drawings. The said fastener essentially comprises a flat buckleplate A, adapted to turn bodily upon one edge as afulcrum and provided with a band-receiving eye or opening B,which receives the lapped ends of the bale-band 0, said plate being further provided with a pair of holding-arm extensions D,having terminal hooks E. These terminal hooks E of the buckle-plate 1 cooperate with a locking-key F, adapted to be passed transversely beneath the band after the plate has been turned bodily upon itself and the hooks E thereof forced beneath the plane of the inner side of the band. This general form of bale-hand fastening can be manipulated with great facility by the turning-tool forming the subject-matter of the present application, and particular reference will now be made to this tool.

The tool as an entirety is in the form of a lever carrying suitable elements or members providing for the bodily turning of the flat buckle-plate or winding element A of the fastener, and this lever, which is designated by the reference-nu meral l, essentially comprises a straight handle portion 2 and a carryingyoke 3, which provides a support for the op erative members of the tool having direct cooperative engagement with the buckle-plate or winding element of the fastener. The straight handle portion 2 of the lever is preferably of a hollow or tubular construction, for the purpose hereinafter explained, and is preferably provided at one end with a loop 4, which affords convenient means whereby the tool may be suspended from a suitable hanger, if desired. From a structural standpoint it is of course unimportant how the lever 1 is constructed-whether integrally or of separate parts--but a preferable construction is shown in the drawings and resides in having the carrying-yoke of a separate piece and provided at the closed side or end thereof with a collar 5, within which is received and rigidly fastened the end of the handle 2, opposite the hanger-loop 4. The carrying-yoke 3 of the lever is preferably of a U form, so that the same will stride the buckle-plate or winding element A of the fastener to provide for the proper positioning of the oppositelyarranged turningheads 6, which are supported by and carried with the yoke 3. The said turning-heads 6 are arranged in diametrically opposite relation and in transverse alinement, the same being respectively located at the innersides of the opposite side arms 3 of the carrying-yoke 3 and contiguous to the terminals or extremities of said side arms, as plainly shown in Fig. l of the drawings. The diametrically opposite relation and transverse alinement of the pair of turning-heads 6 provides for such arrangement of these heads as will permit of the same being engaged with opposite side edges of the rotatable buckle-plate or winding element of the fastener, and thus insure the distributing of the leverage or turning strain uniformly throughout thesaid plate or winding element.

The precise configuration and form of the turning-heads 6 may be materially varied in the practical carrying out of the invention, as it is only necessary that eachof said heads be provided with means whereby the same may be detachably interlocked with the huekle-plate or winding element of the fastener. A simple mechanical expedient for providing this connection resides in constructing each of the turning-heads 6 with a transverse engaging slot or groove 7, extending transversely across the inner face thereof and of a sufficient width to receive therein the edge of the buckle-plate or winding element.

Each of the turning-heads 6 is designed to be positively rotated bya swinging movement of the lever 1 to insure the bodily turning of the buckle-plate or winding element. To secure this result, it is necessary to rotatably support the heads 6 and provide means for imparting a positive rotation thereto. The preferred construction is shown in the drawings and involves forming each turning-head 6 with a bearing-hub 8, projecting from the outer side thereof and loosely journaled in a bearing collar or opening 9, formed in the terminal or end portion of the adjacent side arm 3 of the carrying-yoke, and to prevent dis placement of the bearing-hub of each turning-head from the bearing therefor there is employed a retaining or pivot bolt 10, passing through the bolt-opening 11, formed in the turning-head 6 and its hub, and receiving upon the outer threaded extremity thereof thebinding-nut 12, which binding-nut also serves to hold in place the resetting-cam 13, which constitutes a member of the complete resetting device hereinafter more fully described. It may be observed, however, at this point that the resetting-cam 13, asso ciated with each turning-head, also acts in the capacity of aguardplate,cooperating with the bolt 10 to prevent displacement of the turning-head from its hub, and inasmuch as in the operation of the tool it is necessary for the resetting-cam for each head to turn with the head an interlocking connection between these parts must be provided. The preferred form of interlocking connection consists of a retaining pin or stud l4, projecting from the outer side of the bearing-hub of each turning-head and detachably engaging in an opening 15, formed in the cam 13, fitting against said outer side of the bearing-hub upon the outer side of the side arm 3 receiving the same.

To provide for propelling or actuating the turning heads, the bearing-hubs 8 thereof,

working within the bearing collars or openings 9 of the yoke, are provided with a circumferential or peripheral series of ratchet teeth or notches 16, with which codperate the beveled points 17 of pivotal act uating-pawls 18, seated within pawl-recesses 19, formed in the outer faces of the yoke side arms 3 and pivotally mounted at one end upon pivotbolts 20, passing transversely through the said side arms, as plainly shown in the drawings. The points 17 of the pawls 18 are nor mally and yieldingly held in operative relation to the ratchet-faced hubs 8 of the turninglieads by means of coil-springs 21, arranged in the pawl-recesses 19 and bearing at one end against one side of the pawls and at their other ends against the tension -screws 22, mounted in threaded openings in the edges of the yoke-arms 3" and serving to regulate the tension of the springs 21, while at the same time facilitating the removal and replacing thereof. The pawls 18, which are respectively arranged in the recesses of the opposite yoke-arms 3, are properly retained within their recesses by the cover or guard plates 23, fitted upon the outer sides of the arms 3 over the pawl-recesses 19 and also receiving the bolt. 20, which constitute the pivots for the pawls.

Each of the turning-heads has fitted thereto in the manner explained a resetting-cam 13, and each of said cams is preferably of an approximate U shape and is adapted to normally register within a corresponding complementary approximately U shaped bearingfork 24:, formed at the upper extremity of one of the side slide members 25 of the holdingclutch 26. Each slide member 25 of the holding-clutch 26 is also provided contiguous to the terminal bearing 24: thereof with a longitudinally-disposed guiding-slot 27, which slidably receives the outer extremity of the adjacent pivot-bolt 20, which therefore serves to positively guide the clutch in its sliding or reciprocatory movement. The holding-clutch 26,which,with the pair of cams 13, constitutes a co mplete resetting device for the tool,is preferably in the form of a Ushaped frame conforming substantially to the exterior contour of the U-shaped earrying-yoke 3 of the lever, so that the slide members 25 of the clutch or clutch-frame will be arranged upon the outer sides of the yoke lever-arms 3 and will have a sliding movement with reference thereto. The slide members 25 of the clutch coiistitute the side portionsof the complete clutch-frame, and they are joined rigidly with a sleeve 28 at the closed end of the clutch-frame, said sleeve slidably fitting upon the straighthandle 2 of the lever contiguous to the connection of the lever-handle with the carrying-yoke and receiving-a transverse guide-pin 29, working through a longitudinally-disposed guiding-slot 30, formed in the lever-handle 2, and having exerted thereagainst the pressure of the pressurespring 31, housed Within the tubular levenhandle 2. The pressure of the spring 31 is normally exerted in a direction to move the clutch-frame outward upon the carrying-yoke of the lever, and thus normally hold the terminal hearingforks of the clutchframe in registered interlocking engagement with the reset ting-cams for the turning-heads, thus holding the said turning'heads in normal positions for being slipped upon the huekle-plate or winding element A of the baleband fastener.

In using the tool it simply necessary to bring the engaging slots of the grooves '7 of the turning-heads into register with the opposite side edges of the buckle-plate or wind ing element A and then to slide said turning-heads upon the said plate or element to an intermediate position thereon. Then by a slight back-and-forth swinging movement of the lever-handle the actnating-pawls 18 will be worked over the ratchet-faced hubs 8 of the turning-heads, thus causing said heads to rotate upon their axes a nd serving to bodily turn the buckle-plate or winding element of the fastener. This motion is continued until the buckle-plate or winding element has been completely turned and the lockingkey inserted in place to secure the fastener, after which the turning-heads may he slid off of the buckle-plate.

In connection with the resetting device, consisting of the clutclrfralne and the rotatable cams 13, it should be observed that as the turning-heads 6 are rotated the cams 13, which work therewith, are also turned and caused to have their side portions bear upon the sides of the terminal bearing-forks 24 of the clutchframe, thus causing this frame to be pressed outward toward the swinging end of the lever and against the tension of the pressurespring 31. In this action of the cams 13 the U-shaped portions thereof turn entirely out of the forks 24-; but immediately upon disengaging the turningheads from the buckleplate or winding element the spring 31 comes into action and forces the clutch-frame 26 in a direction toward the turning-heads, thus causing the terminal bearing-forks 24E to bear against the cams 13 and turn the same back upon their axes and into position for receiving thereover the complete forks 24, thereby returning all parts of the tool to normal positions, as will be readily understood from the foregoing description.

From the foregoing it is thought that the construction,operation,and many advantages of the herein-described turning-tool will be readily apparent to those skilled in the art without further description, and it will he understood that various changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
