MACHINE FOR APPLYING FOXING TO RUBBER SHOES.

Application led April 7,

To all whom t may concern:

Be it known that I, Louis A. CASGRAIN, a citizen of the United States, residing at Beverly, in the county of Essex and State of Massachusetts, have invented certain Improvements in Machines for Applying Foxing to lubber Shoes, of which the following description, in. connection with theaccompanying drawings, is a specification, like reference characters on the ldrawings indicating like parts in the several figures. This invention relates to the manufacture of rubber footwear' such as tennis shoes, sneakers, arctics and the like. The invention is herein set forth with particular reference to the application of foxing such as is employed as an intermediate strip between the edges of the soles and the marginal portions of the uppers of such shoes.

Isleretofore, so far as I am'aware, the application of the foxing has always been eHected by hand, requirinrqir the preliminary application of cement to 'the shoe upper while on the last and then a careful'laying of a strip of material suitable for foXing upon the cement and running a roller along the foxing to ensure its proper contact with the cement in orde-r that the later vulcanizing operation may effect a secure and completely waterproof joint. It has been necessary, in order to prepare the foXing for application as above described, first to form the rubber compound into a sheet and then to slit it to form strips, this necessarily requiring-the use of a machine for manufacturing the sheet and also requiring an operation of stripping the sheet and then laying the strips between. protecting sheets in order that the rubber may not become dry cured.

In another' application Ser. No. 288,230, filed by me April 7 1919, I have disclosed a method and means for making foxing in strip form of uniform width which is coiled with an intercoiled strip of paper or cloth so that the coiled strips of foxing will not stick together.

An important object of the present invention is to avoid the time and expense required for preliminarily forming the sheet of rubber compound and then converting it into strips, and applying the strips by the hand operation above described.

With this object in view, this invention in one aspect comprises applying a foxing 1919. Serial No. 288,229.

strip of proper width and thickness to the shoe by pressure effected through the medium of a backing strip of non-adhesive material which has been intercoiled therewith.

In the method of applying the foxing as heretofore proposed, it has been customary to produce the appearance of a line of stitches along the edge of ther foXing which overlaps the portion ofthe upper above the shoe bottom, such appearance of stitches being produced by the manual use of a serrated wheel. This requires the expenditure of considerable labor and the necessity of skill to produce a good appearance. An important feature of this invention is that the same power which is employed to feed the strip to position for application to the shoe serves also to form a line of indentations along one margin of the strip of foxing to produce the eHect of stitches.

In the drawings, I have illustrated one em-l method.

In said drawings,

Fig. 1 is a side elevation, partly broken out.

Fig. 2 is a perspective view of portions of the machine shown in Fig. 1, looking from a point somewhat to the left and behind the Fig. 1 view.

Fig. 3 represents a detail section through co-acting portions of the feeding and strip marking rolls or wheels.

A frame standard 12 is provided with two arms 1B, 14, the former having a shaft or spindle to support the reel 15 which supplies the two-ply strips of foxing a and nomad hesive intercoiled paper or cloth strip b.

A take-up reel 16 for the strip b is rotatably mounted upon one end of an arm 17 pivotally connected at 18 to the arm 14 and having a spring 19 so connected toit as to a little more than counter-balance the weight of the reel 16 and the material which may be wound thereupon as hereinafter described.

`Said spring also serves to co-operate in attaining a friction drive of the reel 16 as hereinafter explained.

Mounted in bearings carried by a suitable frame housing 20 is a shaft 21 carrying the upper feed wheel 22 which preferably has iianges as best illustrated in Fig. 8. A lower feed wheel 23, which is also the foxing ap- Cil plier hereinafter described is mounted and arranged to be in valmost peripheral contact with the Wheel 22 and is formed with a pe ripheral toothed or knurled portion 2d, and') having such shape as to indent or impress thel toxing'material with a line similar to that which has been heretofore produced by the serrated Wheel operated by hand.

i brush 25 'the bristles of which arein spaced groups is carried by a shaft 26 mounted in suitable bearings substantially at a right angle to the shaiitoi'whe'el 23. A pinion 27 carried by sha'lit 26 meshes with a gear 2S carried a shaft 29 mounted in suitable bearings provided in the :trame oit' the machine. A. suitable guard iframe lfor the gearing 27, 2S is indicated at 30. i

"llhe shaft 29 driven by slreuT gearing 31, one member oi? which is carried by the shaft 21.

Power to operate the machine `A`may beapplied to the shaft of either of the Wheels 22, ln Fig. l,- l' have illustrated a drive belt 32 litting a pulley carried by shaft2l. The shaft 2l carries a spur gear 33 meshing with a spur gear Sil carried by the sha'it oAWheel 23, these tnospurgears being indicated by flot-ted lines in Fig. l.

rlhe shaft of Wheel `23`carries a pulley 35 connected by a belt 36 with a pulley 37 which is carried'by the shaft or spindle ot the take-up Wheel 16.

i suitably mounted," and preferably adjustable, guide for the shoe is indicated at 38 in Figs. l and 2.

'iny suitable means for starting and stopping the machine may be employed such as any preferred 'form of clutch operated by an arm 89 carried by a rockshait 4:0, the latterhaving an arm il `to which is connected any suitable treadle rod 42. In producing the supply ot material consisting of the vin ter-coiled strips o and L formed upon a reel such as indicated at 1.5, the strip of .toning being freshly made and immediately coiled as explained in the application ller. lilo. 288,230 hereinbetore referred to, two advantages result. llirst, the toning is so protected that it does not need to be used as promptly alter making it as h as been necessary heretotore'where the rubber compound is formed into sheets and then out into strips. Second` it provides a supply tor use as tollows-The two-ply strip 66,7), is led from the reel l5 over the roll 22 between the flanges thereof and under and partly around the Wheel 23, the strip ot' forging a being outermost upon the Wheel 23 so that said Wheel can serve as the applier to lay the toning on the proper portion 'of the shoe upper e carried by the last c, said upper overlapping the insole Z as is customary. 'lhe operator. holding the last and the shoe parts thereon in hishands, guides it in the `lniurled or toothed portion direction ot the arrow ,fr in Fig. l under the Wheel 23, employing the guide 38 it desired to insure the location ot the stitch indented edge ot' the foxing at the proper distance from the shoe bottom as indicated in Fig. 2. ln practice, it will be preferable to provide the supply reel l5 With 'suiiicient length of the strip Z) longer thanthe strip a so that, When the machine is threaded up the end of the strip lo can be carried up and attached to the take-up reel 16.

firs the operator feeds' theshoe along as described, Whatever amount oit upward pressure against the applyingwheel 23 as may `be necessary will. be enerte l to cause the stitch indented j ortioifi ot the timing to be uniformly and iirinly laid in place. its the movement oi the Work proceeds1 the revolving tufts or groups ot bristles 25 of the brush act to Wipe down the other edge portion of the toning a over that portion et the upper which lies upon the insole. By er ranging the brush bristles in sepa 'ated groups or tufts, such spaces are lett bet-Ween them that the bristles Will not interfere with each other they tollenT each other around. That is, each tuiit or bunch will perform its ilunction without causing such lateral flexing ot other bristles `aswould tend to cause displacement ot the edge por tion of the oXing which is laid over upon the shoe bottom as described.

The object ot the iriction drive ot the take-up reel 16, by means of the belt 8G in connection with the yielding1 mountins' ot' carrier 17, 19, is to regulate the tension or the pulley upon the strip?) which is drawn on to the reel i6 in the direction of the arrow y. As the diameter et the 'Winding or coiling upon the spool or hub of reel 16 increases, the belt 36 will slip sutiiciently to insure the uniformity oit the pull on the strip o.

As has been stated., the wheels l not only serve by their co-actionto feed the tuo ply strip but they also coast to iiorm alo j one edge ot' the toning a line of indentations to imitate stitching. Since said lim` of indentations is elllected bv means oi' the of the wheel 23, the stitch impressions are effected by means of power imparted by the machine itself instead ot requiring any manual exertion upon the part ot the operator. Of course, to some extent the stitch indentations entend into theintereoiled protecting strip b and since the two strips are still together when they reach the point Where the shoe is held against them by the operator, the'pressure of the Work against the applying Wheel by the operator does not press out Or remove the indentations in the toning strip a.

The 'tiro wheels strip at a predetermined speed su ...d f, .ad

28 feed the tiro-ply dicient to llo permit the operator so to manipulate the edge of the shoe while in contact with the wheel 23 as to effect accurate and uniform laying of the foXing. The operator has nothing to do except to properly manipulate the lasted shoe parts, starting and stopping the machine whenever desired by means of suitable treadle and clutch mechanism such as hereinbefore referred to. He does not handle the foxing because the paper or cloth backing strip b acts as a conveyor to present the foxing to the shoe at the point where the shoe is placed in contact with wheel 23, the paper itself following partly around. said wheel 23 and then being rewound out of the way on the spool or reel 16.
