APPARATUS FOR ATIAGHING BELT HOOKS 'IO BELTS AND THE LIKE.

Application filed December 31, 1921. Serial No. 526,340.

To all whom it may concern:

Be it lmownthat I, Josrlrn C. CONN, a

citizen or the United States, and a resident of Boonton, Morris County, State of New Jersey, have invented an Improvement in Apparatus for Attaching Belt Hooks t-o Belts and the like, of which the following is a. specification.

The present invention relates to an improvement in apparatus for attach ng belt hooks to belts and the like. One of the ob"- jects of this invention is to provide a hand operated device for applying belt hooksand the like in such a manner that the pro-geoting ends'oi' the hooks will be in exact alignment and relates more particularly to set-- ting hooks that are of the type intended to accommodate akey or pintl'e to form a hinge connection between the connected ends of the belt.

Belt hooks the character referred to are marketed usually in gangs or cards comprising a suitable support for a plurality of hooks arranged with their respective parts in alignment spaced equal distances apart, usually the distance which is appropriate both to the size of the-hooks and to the size of the belt to which the hooks are to be applied. In use, one row of hooks is applied to one end of the belt in a predetermined position and a similar row of hooks is applied. to the other end of the belt in a 'ively oit'set position with respect to the mentioned set so that, when the ends of the belt are brought together the rounded or bent outer ends or loops or the hooks seemed to one end of the belt will mesh with the corresponding loops of the other end of the belt and a key or pintle is passed through the intermeshed loops to form a hinge joint.

In practice, various means have been employed for attaching hooks of this character to the ends of belts. One 01 the objects of this invention is to provide a device which will effectively embed the penetrating ends or the prongs of the hooks in very wide or thick belting which owing to the extreme toughness of the leather or other material of the belt offers great resistance to the simultaneous passage of the prongs therethrough. This resistance has in fact imposed a. limitation upon the size of attaching devices which simultaneously attach hooks to large belts, so that it is customary to use smaller devices and to repeat the operation in successive sections or increments as man t1mes, as may be necessary to attach all of the hooks required for a single edge or end of the belt. This not only takes considerable time but it also involves the danger of the hooks not being positioned evenly or, with their outer or loop ends in exact alignment. The importance of having accurate allgnment will be readily understood in View of the necessity of transmitting the strain evenly on each belt hook across the entire width of the belt and of the connecting element or pint-1e rather than across a relatively narrow or restricted portions thereof.

The difliculties and shortcomings are obviated by using my improved apparatus which causes the hooks to be successively pressed into penetrating engagement with the belt by application of closing pressure to the hook shanks successively and in a number of increments depending upon the thickness of the belt and other considerations. In other words, instead oi simultaneously pressing in the prongs of all of the hooks at one and the same time, as is now commonly done, I provice an apparatusto press the prongs of each hook independently to a predetermined degree and repeat the pressing operation over the whole set or row until the required degree of penetration of all the prongs is attained. If both the hiltand the loop of the hook members are held rigidly during the entire pressing or penetrating operation, there would be a tendency of the hooks to strain the material of the belt; Accordingly, I provide my apparatus with means to hold both the belt and the hooks only until the prongs are sufficiently engaged with the belt to support it independently of other means. I then continue the pressing in of the prongs either with the belt free to move endwise or with the hooks tree'to move endwise. uniformly to maintain alignment of the loop ends Thus, no straining or tearing of the material is encountered as the penetration progresses and no undue strain or stress is imposed upon the apparatus employed.

By applying pressure to each hook indii' 'idua-lly. I am enabled to attach at one operation the necessary or desired number ct hooks to any width 01": belting or other material that may be required. Furthermore, the loop ends of the extending or exposed portions of the hooks, when in attached position, will all be in exact align ment and when used to form the hinge joint between the belt ends, the tension strain will be distributed equally across the entire width of the belt through a suitable connecting member such as a key or pintle made of raw hide, bamboo, or other suitable material.

One embodiment of apparatus suitable for practicing the method hereinabove described is illustrated in the drawings accompanying the present specification and in which Figure 1 is a side elevation,

Figure 13, a diagrammatic view illustrating the operation of the presser members and their actuating means.

The apparatus illustrated in the drawings comprises broadly a suitable base or frame means for holding a belt end in ct fective operative position, means for supporting a plurality of belt hooks in position to have their prongs pressed intd penetrat ing engagement with the belt end and means for pressing said prongs into penetrating engagement with the belt material. In de tail, a preferred form of this apparatus includes a rigid substantially arch-shaped frame 1, having uprights supporting spaced longitudinally extending cross members which form carriage supporting and guiding ways 1, between which are located longitudinally slid-able cam or wedge carriers 2, Figures 5 and 8, provided with wedge cams 3 and supported and slidable upon transversely extending cross members 01 the frame. A bracket 5 at one end of the frame supports a pivot mounting 6 for a comb or hook holder 7. the other end of which is supported in a bearing 8 secured to a bracket therewith.

9 and locked in position by a removable pin 10.

The belt holding mechanism includes a pair of cooperating, transversely slidable the apparatus, said sliding members 2 being secured together at both ends by cross members 15 and 16. Thus, when the members 2 are moved longitudinally in the direction of the arrows, Figure 3, the gripping members 11 will be moved transversely toward each other andinto gripping contact with an interposed article such as a belt 17 and against pressure of the springs 12. When the sliding members 2 are pulled. back or moved in the opposite direction, the gripping members 11 will move away from each other thus releasing the belt 17, the outward move ment of said members 11 being effected by means of the springs 12. In order to permit more effective gripping engagement be tween the grippers and the belt, the inner or effective belt engaging edges of the grip pers are slightly grooved or otherwise deformed.

The comb or holder 7 hereinabove referred to is provided with a plurality of hook spacing members or teeth 18 forming hook receiving recesses, Figures 8, 9 and 10, havin aligned perforations 20 which form in eli ect a continuous passageway for a locking or hook supporting rod 21 slidably movable into and out of engagement In placing or assembling the hook-s for attachment, the loop ends thereof are inserted into the recesses between the teeth of the holder and the rod 21 is pushed into place so that when the holder is arranged as shown in Figures 8 to 10 inclusive, the hooks will hang suspended upon the said rod 21 in spaced relation with their shanks extended and straddling the end of the belt 17 and in position to be acted upon by presser mechanism hereinafter to be de scribed. The con-1b or holder T being pivotally mounted at may be readily swung into and out oi position so that it is remoable or readily accessible in order to position the hooks therein.

The attaching device as illustrated also includes cooperating sets of hook pressing members or pressers 22 each slidable trans versely toward and away from the belt 17. The inner ends of each opposed pair of pressing members 22 are arranged to engage the respective opposed shanks of a single 1 ,aaeeoe hook. In the illustrated embodiment of a preferred form of hook attaching appara tus, the pressers are supported upon and slide transversely across the upper surfaces of the grippers 11, the gripper actuating slide rods 2, and the bed or frame, being retained in proper transverse alignment between abutment guides 23 and 24 located at the respective ends of the sets of presscrs. To maintain substantial longitudinal ali nment and to permit the pressers to be moved as sets, each set is provided with suitable connecting means which will permit the de-- sired set movement without hindering a certain amount of individual movement as between. adjacent pressers in the same set, said means being shown as bars or rods 25 and 26 passing through holes 27 in the pressers, Figure 7, aligned to form a substantially continuous passageway through each set. The upper or exposed edges of the pressers are. cut away uniformly as at 28, to provide, when the pressers in each set are aligned, a channel for accommodating a part or parts of the presser actuating mechanism hereinafter to be described and to present thereto outwardly disposed contact surfaces 29 positioned to cooperate with said part or parts of the actuating mechanism.

As shown in the drawings and more particularly in Figures 8, l1 and 12. thereof a preferred form of presser actuating mechanism includes a carriage adapted to ride upon bearings provided by the ways a and arched so that it may readily pass back and forth above the hook holder 7 and the sliding pressers 22. The framework of the can riagte comprises side plates 30 and 31, Figure 11. end braces 32 and 33 and a central brace 34;, lugs 35 being formed on the lower corners of the plates 30 and 31 to guide the carriage and retain it in operative position on the ways 4.

Between the side plates are cooperating: roll carrying members or carriers 36 and 37 having longitudinally extending right and left hand threaded holes respectively adapted to engage and receive a screw having right and left hand threaded portions 38 and 39 respectively. The brace 34 carries two depending lugs 40 and 41,, shown in dotted lines, Figure 11. which are positioned between flanges 42 and 43 on the screw to prevent endwise movement thereof and to maintain the carriers in central position. The carriers 36 and 37 are provided with guiding recesses or slots at and 4.5 respectively, horizontal surfaces of which engage and slide upon surfaces of guide pins a6 and 47 respectively. which are supported between the. side plates 30 and 31, being retained in operative position by locking: pins The - ar riers 36 and 37 are provided. with studs 49 and 50 respectively, having; rolls 51 and supported on ball bearings at their respective depending ends, In the form of device shown in the drawings, the screw passes through the studs 49 and 50 as well as through the corresponding carriers as described above, and is provided at each end with a grip 52' secured in any suitable man-. ner.

In operating my belt hook attaching device the hooks required for one end oi' a given belt are positioned in the hook holder 7 which is then secured in operative position as hereinabove described. The belt end then inserted in a vertical direction between the grippers 11 until the edge passes between the spaced prongs of the hooks and bears against the outer ends of the row of depending teeth or projections l8 of the comb or holder. The operator then pushes the slides 2 and the wedge portions carried thereby in a direction to move the grippers ll into belt gripping position, where they remain with no other locking; required, Both sets of pressers are then pushed by hand into engagement with the hook shanks and the rolls on the carriage are positioned by rotating the screw by means of the hand grips 52 so that said rolls will readily fit into the recesses or grooves 28 when the carriage positioned on the ways 4-. A relatively slight adjustment of the roll iarriers by means of the screw brings the rolls into contact with surfaces 29 of both sets of pressers and the pressers are initially aligns-d by a run of the carriage in one direction. Additional turns of the screw will to bring the rolls closer together and as they move back and forth in rolling contact with the surfaces 29 they exert actuating pressure thereon and i'orce the respective pressers against the hook shanks in controllable increments. is soon as the points of the prongs have engaged the belt suiiiciently to hold it in position without the aid of the gri 'ipers, the slides 2 will be drawn back thus permitting the grippers to release the belt which will then hang: suspended on the rod 2i by means of the loops of the hooks.

Repeated traverses or runs of the carriage together with further turns of the roll adjusting screw will continue he reni-itratinn movei'nent of the prongs into the belt or other material until they reach the required position or substantially as shown in Figure 10. whereupon the roll carriage is lifted off or otherwise removed and the rod 2].

withdrawn from the hook holder to toward and away therefrom, each member 111 said set being positioned to engage and press a corresponding hook shank toward the belt, and means for actuating said members.
