Application le. November 22, 1924, Serial No. 751,698, and in France October 24, 1924.l
This invention relates to a machine intended for mechanically sta-pling together two thicknesses of material', -especially thicknesses of leather in the manufacture of trav 5 elling bags or the like.
The characteristic feature of the invention consists in the attachment of the staples in a single operation, automatic charging means being provided for feeding a staple l in front of each hammer so that the machine is always ready for use.
The annexed drawings show by Way of example one method of carrying the invention into practice, but it is to be clearly l understood that the machine may be modified as to a whole or as to they details hereinafter described according to the class vof work to be carried out. v
In the accompanying drawings Fig. 1 is a plan of the machine. Fig. 2 is a front elevation. Fig. 3 is a side elevation with parts in section.
Fig. 4E is a part section of a feeding device.
Fig. 5 is a section on the line C- D of Fig. Li.
Figs. 6 and 7 are sectional details of the feeding device, taken on the lines A-B and C-D respectively of Fig. 4:.
Fig. 8 is a detail side elevation and plan view of the pressing plunger of the staple feeding magazine. f
Fig. 9 is a view of the mechanism for opening the feeding devices so as to allow for the insertion of the portions of the bag or the like which have to be attached together.
Fig. 10 is a front view of the back plate which constitutes an anvil and causes the ends of the staples to be turned over.
The machine comprises a main framework 1, which may be a casting, the sides of which are parallel and provided with two dovetail guides 2 and 3. Gn these guides is adapted to slide a carriage 4 carrying a series of driving hammers 5, which are easily interchangeable. These hammers consist each of an elongated steel plate. They are intended to force the staples through'the thicknesses of leather and into Contact with an anvil 1a which turns over their extremities so as to obtain a perfect attachment of the parts together.
The carriage 4L carrying the hammers is operated by a Shaft 6 having an external screw thread 7 of steep pitch screwing into the internally screw threaded nut memberv 8 connected to .the carriage.
The shaft 6 1s supported towards its rear It is provided with a worm wheel 10 operated by the worm 11, which latter is operated by the lshaft12-carrying the fly wheel 13.
As willbe'seen, asimpleoperation of the fly wheel 13 causes theA carriage and vthe hamm-ers 5 to move forward to do their work.y The number of the hammers varies according tothe size of the bags or the like to be manufactured.
The extremities of the staples are turned over by means of the back plate 11i (Fig. 10) in which are provided a plurality of hollow recesses 15, one corresponding to each hammer. This back plate may be cast with the framework andv is so shaped as to facilitatethe reception on the inner face thereof p one of the folded pieces of leather'or the The back plate 14, carries apspindle 16, provided with` a certain number of cams 17,
which are rotated by turning the spindle 16,
by means of a handle 18. 'A plurality of car- Tiers-19, p lvotally mounted at one'l of their vends upon a shaft 20, extends substantially in parallelism with the anvil 1li, each of said carriers having secured thereto a staple magazine 24. A carrier 19 and magazine 24 is provided for each hammer 5, and a cam 17 is provided for each carrier. The cams 17 are normally secured to the spindle 16, but are .relatively adjustable thereon. The
Aforegoing construction enables the workmen to rotate the spindle 16 to bring the cams 17 successively into engagement with the carriers 19, causing said carriers to be moved, one after therother,thus moving away the various groups of feeding devices from the anvil and facilitating the insertion of the pieces of leather or the like which are to be attached together.
When one of the cams ceases to operate, a pull spring 21 brings the carrier 19 towards the anvil, thus closing the jaw-like opening formed between the carrier and the anvil, whereby the leatheris clamped between the anvil 11i and the extremities of a staple guiding member 22 which serves to guide the staples 23 at the moment they are forced forward by the hammer 5.
When one of the staples has been fed in front of a hammer 5, by mechanism presently to be described, a simpl-e operation of the fly wheel 13 causes the carriage 4 to be actuated and to move towards the anvil, carrying with it the plurality of hammers and causing the whole series of sta-ples to penetrate the leather simultaneously, the extremities of the staples being then turned over in the recesses 15 of the. anvil 14.
The magazine or feeding device for the staples is shown in Figs. 4, 5, 6, 7' and 8. Each magazine preferably consists of a sheet metal tube 24 of square cross section from one sid-e of which a pair of longitudinally extending wings project. These wings, which are also of sheet metal are adapted to be bent into engagement with the inclined sides of the carriers 19, as shown in Fig. 5, thus serving to vconnect the magazine in dove tail engagement with its respective carrier.4
Each carrier 19, as clearly'shown in Figs. 4, 5 and 6, consists of two spaced parallel members, one of which is engaged by the cam 17 and has the magazine tube 24 secured thereto, as described above, while the other member to which the reference character 19a is applied, is spaced slightly below the magazine tube 24 and serves as a support for the connecting leg of the staples. As shown in Fig. 6, this connecting leg of the staples is located between one of thesides of the magazine tube, while the pointed prongs of the staples extend about the two adjacent sides of the tube. Each magazine is provided at its outer end with a smalhchannelled, staplefeed or guiding member 22, suitably secured to the magazine tube 24, and having its inner face vslotted or otherwise provided withan opening through which the staples 23 are fed into the interior of the guiding member.
The movement of the staples 23 into the guiding member 22 is obtained by means of a helical compression spring 26 located in the interior of the magazine 24. y This spring 26 pushes forwarda plate 27 provided with three fingers or extensions 28 which slide along three grooves 29 provided on the three faces of thev magazine 24.v
The plate pushes the staples progressively so that the latter come one by one against the wall of the channel formed in the guiding member 22 and in front of each hammer.
The invention also contemplates the employment of staples of larger size. For instance, the staples may be of curved shape for fastening together curved portions of the bag or the like.
Moreover where the portions of the bag or the like are rounded, the staples may be of corresponding shape. Generally,jthey may be bent in any manner to conform` to the shape of the parts for which they are to be used. They may be constituted of stampings in metal provided with Vgripping tongues, or fixed by means of smaller staples.` What I claim and desire to secureA by Letters Pat-ent in the United States of America V1. In a machine for stapling together thicknesses of material, especiallyy leather, the combination of a framework, `an anvil carried by the said framework, a carriage adapted to reciprocate with respect to the said anvil, a plurality of hammers attached to the said carriage, means for reciprocating said carriage, and a plurality of staple carrying magazines, one for each of said hammers, pivotally secured to said anvil.
Y 2. A machine, as set forth in claim 1, in which each of the magazines is provided with a staple guiding member having a channel in alignment with its respective hammer,
through which the hammer is adapted to be moved bythe reciprocation of said carriage to force the staples through the material and clinch them against the anvil.
8. In a machine as claimed in claim 1 aV construction in which vthe carriage carrying the hammers is operated by means of a shaftV rotatable but not longitudinally slidable in the framework, the said shaft being provided with a screw threaded portion engaging a nut member on the carriage, together with means for rotating the said' shaft such as a worm wheel thereon meshing with a worm on another shaft, which latter shaft is provided wi'th a Hy wheel, substantially as dey scribed.
4. A machine as setforth in claim 1in which are provided, a plurality of springs for normally urging the magazines toward Y the anvil to clampl the material against said anvil, cams for moving saidl magazines away from said anvil, and means foractuating said cams.
5. In a machine as claimed in claim 1 a construction in which the magazine feeders signature. y
