MACHINE FOR FEEDING AND ATTACHING HANDS T0 BOOTS OR SHOES.

SPECIFICATION forming part of Letters Patent No. 408,895, dated August 13, 1889.

Application filed April 16, 1887. Serial No. 234.989. (No model.)

To all whom it may concern..-

Be it known that I, FREEBORN F. RAY- MOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a newV and useful Improvement in Machines for Feeding and Attaching Rands to the Soles of Boots or Shoes, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forining a part of this specication, in explaining its nature, in which- Figure l represents in vertical section my Fig. 2. is a view, part in horizontal section and part in plan, upon a line below the teinplet-plate and above the bed upon which the rand former moves. Figs. 8, 4, and 5 represent in plan view portions of the welt forming and feeding device in various positions. Fig. 6 is a View illustrating the operation of the welt-pressure plate, to which reference is hereinafter made. Figs. 7, S, and 9 show modified forms of the invention, to which reference will hereinafter be made. Fig. 10 is a view in elevation of a portion of the head of the machine. Fig. l1 is a detail view in vertical section taken through the templet. Fig. 12 is a perspective view of a part of the templet and rand-former inverted. Figs. 13, 14, and 15 are views of a shoe, illustrating the operation of the machine. p

The object of the invention is to feed rands into position for attachment to the outsole of a boot or shoe to form it to the shape of the edge of the outsole at the heel end, and for attaching it to the outsole while thus held formed to the outsole, and subsequently to mold it under pressure, so as to cause itto be set down somewhat with the edge of the outsole in relation to the remainder of the sole at the heel-seat. The invention therefore involves a method and means for carrying it into effect.

The means which I have illustrated are represented in the drawings, as follows:

A represents a last or work-support. 1t is mounted upon a rod or support a, which is vertically movable in the jack-post a. This jack-post is mounted upon the slide-plate a2. The rod or support a is represented as made vertically movable by means of the 'togglehead a3, the toggle a, lever a5, pivoted at a6 and connected with the toggle by'means of the link a7, and the cam as on the vertical shaft a, having a cam-groove am, which receives a cam-pin upon the end of the arm a of the lever 0.5.,

B is a templet, preferably stationary, and which is provided with holes or pcrforations b, through which the rand-attaching nails are driven. This templet has a surface b', which is fiat or .very slightly concave at its center, and which isbevelcd or out away upon its sides and back, as at b2, substantially of the form of a rand, to provide a rand-former.

(See Figs. 1 and 11.) This provides the templet with a section which is adapted to bear upon the surface of the outsole at the heel end thereof well within the edge of the sole, and which receives the upward pressure of the work-support A, and the templet is so fashioned or shaped outside this section b upon its sides and back as to provide a recess between the upper surface of the outsole, when in place, and the inclined surface b2 of the templet, which is of a shape to receive the rand. This inclined surface b2 may be continuous from the flat surface b backward and upward about the width of the rand used, Vor it may end against a narrow shoulder b3, as shown in Fig. 11. i

Behind the last or work-supportA is a post C, which is represented as vertically adjustable in its stand c by means'of the screw c and nut c2, and this post supports a table C in two parts c3 c4. (See Fig. 7.) Each of these parts has a dovetailed tongue c5, Fig. l,which extends into a dovetail recess' cut across the upper surface of the post C, and the two sections 03 c4 are provided with movements toward and from each other by means of the right-and-left screw c. Each of these sections c3 c4 of the table extends forward, and they are curved at c7 cs, respectively, to approximate the curve of the heel end of the outsole.

The object in making the table in two parts is to provide the opening O2, bounded by the edges cT es, with adjustment as to size, in order that the table may be set closely to the IOO heel-edge of an outsole of any size. The table Y sole.

also acts to support the rand and direct its movement to the surface of the sole, so that its upper surface preferably should be set to be a trifle above the upper surface of the out- 'lhis table is covered by the templet and the templet plate or support, so that there is formed between its upper surface and the under surface of thc templet-plate and templet a guiding space or recess, along which the rand may be moved while it is being fed to the templet-former.

To move the rand into position, I prefer to employ a flexible carrier and former D. (See Figs. 2, 3, 4, and This carrier and former may be made of rawhide or leather, or springsteel, or of any other suitable material, and it is attached at each end to the ends d of the levers d2. These levers are pivoted, respectively, at d3 d4 to a sliding support or block d5, which is provided with a horizontal movement toward and from the templet by means of the cam-groove d in the cam-disk (Z7 upon the vertical shaft a, the sliding support or block d having a cam-pin cls, which enters the cam-groove d, and being guided in the frame of the machine in a suitable guideway and held in place preferably by capplates. (See Fig. 2.) The levers d2 are connected with the springs d di, which keep the ends d' separated from each' other and the flexible carrier D substantially taut and also straight, excepting while engaged in forming the rand about the former and upon the surface of the outsole.

In operation the rand is placed, preferably, in a slightly-tempered condition upon the table C in front of the exible carrier D, the boot or shoe mounted upon the last or work support, and the last or work-support moved into position to bring the rod or movable support ay over the toggle-head a3 and the heel end of the outsole beneath the templet B. The machine is then set in operation. The cam as moves the work-support or last A upward and brings the heel end of the outsole in contact with. the under surface of the templet. This is immediately followed by the forward movement of the slide-plate d and levers or arms (Z2, which cause the rand-carrier to move the rand upon the table until its central section is moved between the templetformer and the upper surface of the outsole. (See Fig. l.) The movement of the lever-support (Z5 continuing causes the rand to be turned about the former between the under surface of the templet and the outsole until the entire rand has been brought into shape* that is, curved to fit the outer edge of the heelseat or heel end of the outsole-and the parts are then in the position shown in Fig. 5.

The cam for moving the levers d2 to cause the rand to be fed and formed is timed to.

move it immediately at the end of the upward movement of the work-support, and this is followed by the immediate driving of t-he randattaching fastenings or nails. These fastenings are fed, preferably, automatically to the holes l) of the templet by a nail-carrier E,

which is moved from a position in which it receives nails or fastenings from a nail or fastening making device (not shown) to a p0- sition to deliver them to the holes b by means of the cam e on the vertical shafts a, which cam has the cam-groove e', which receives the pin e2, extending upward from the plate es, by which the nail or fastening carrieris secured, or at the end of which it is formed.

The cam e is timed to move thenail-ca-rrier into position to deliver its fastenings or nails immediately after the completion of the feeding forward of the rand, so that there is immediately delivered to the holes of the templet the nails or fastenin gs for attaching the rand.

F is a gang or group of drivers carried by a plate f, supported by a head f. Thishead is shown as moved by the cams f 2 f 3, each of which has a cam-groovef4, and these camgrooves receive the cam-pins f5, extending laterally from the head f. The cams f2 are carried upon the horizontal shaft f, which has bea-rings at f7 in the bracket fs and atf in the bracket f 10, and there is attached to the back end of this shaft fi a bevel-gear f, which meshes with the bevel-gearf12 upon the upper end of the vertical shaft f. The

cams f 2 f3 are so timed as to move the drivers y downward through the holes in the nail-carrier and templet to drive the nails from the templet immediately upon the movement of the carrier intoposition, so that immediately after the holes in t-he nail or fastening carrier register with the holes in the templet the drivers enter the holes and drive the fastenings into the rand and out sole or soles.

It will thus be seen that the various operations of the parts-namely, the upward movement of the last or work-support, the feeding Vand forming of the rand, the feeding of the rand-attachin g nails,an d the drivingthereofare successive automatic operations, and that they are all caused by cams, so that they can all take place at least in one complete rotation of the shaft a9, or upon any part of said rotation desired.

The fastenings or nails driven may not only be used for securing the rand to the sole' or soles, butalso for the purpose of securing the outsole, upper, and counter to the insole, thereby providing a very strong and rigid heel-seat. Immediately upon the driving of the fastenings the drivers are lifted from the templet and nail-carrier, and the nail-carrier is moved back to its original position to receive another load of nails or fastenings.

To fiatten the rand upon the outsole, and also to mold the heel and outsole to some eX- tent, so that the uppersu-rface of the rand shall be made level or very nearly level with the surface of the sole inclosed by it, I use a pressure plate G, (sec Fig. 11,) which pressure plate preferably forms part of the templet plate, and is moved in suitable guides g from one side of the machine TOO IlO

bring the imperforate forming-surface Gr', having any desired shape, over the last or work-support. It is moved into position after the driving of the rand-attachin g nails or fastenings, and when this plate is used the cam a8 is constructed so as to move the last or work-support A downward immediately upon the driving of said fastenings to permit the horizontal movement of said pressure-plate into position, and then to immediately move the last or work-support with the shoe and the attached rand upward, so that the sole and attached rand are brought against the under surface thereof and pressed, molded, or flattened. This pressure-plate G is moved into and out of position by means of the camgroove g in the under surface of the cam dT (see Figs. l and 6) and thelever g2, which is pivoted at gand which is connected at one end with the said pressure-plate G and at the other end has a cam-pin g4, which enters the cam-groove g', so that upon the rotation of the cam .the plate is at the proper time moved into position and held there during the upward movement of the work -support and work in relation thereto, and then upon the downward movement of the work-support returned to its original position and held until it is again operated. After the driving of the attaching nails or fastenings into the rand the rand carrier D is immediately moved backward. At the end of its forward position the levers or arms d2, it will be seen, have been turned upon their centers, so that their ends d approach each other to cause the carrier D to press or draw the rand properly upon the templet-former. Of course this movement is in opposition to the stress of the springs d d10. Upon their backward movement they are moved to their original position by the springs-that is, they are caused to assume the posit-ion in relation to each other shown in Figs. 2 and 3.

In Fig. 7, in lieu of a carrier supported by levers (l2, I have shown the levers or arms d2 as provided with jaws for grasping the endsA of a rand to hold it during their feeding and forming movement, which is fully shown in detail perspective by Fig. 9. This holder or carrier I consider to be the equivalent of the carrier D, although it is not as desirable a form of construction.

In Fig. 8 I show the feeding and forming levers cl2, provided with rolls at their inner ends and as hung in a somewhat different manner from that shown in Fig. 3, the ends of the lever being brought quite closely together, and the rolls being arranged to bear against the back edge or thick part of the rand near the center of its length, and upon the forward movement of the levers the rand is pushed into the space between the upper surface of the outsole and the under surface of the templet at the back end of the heel, and this is about the center of the length'of the rand, and from this point the rolls are caused by the advancing movement of the levers to be separated and to press against the back edge of the rand with a graduallyadvancing movement, and to thus turn each section thereof into the recess between the outsole and the templet and about the former until the entire rand has been turned or brought to the desired shape. While considering this as an equivalent for that employing the carrier D, yet it is not as desirable a construction. The vertical shaft a9 preferably is rotated or turned by means of a worm-wheel I-I and arm h on the driving-shaft h.

In operation the rand is first placed upon the table C in front of the rand feeding and forming devices. The boot or shoe is mounted upon the last or work-support and the jack moved into position beneath the templet. The machine is then started. The last or work-support is moved upward to bring the heel end of the soles against the under surface of the templet B and is pressed against the same with any desired compression. This upward movement of the last or work-support is immediately followed by the forward movement of the rand feeding and forming devices and the fitting of the rand upon the vtemplet-former to the outsole so that it is in a position to be attached thereto by its attaching nails or fastenings.V The nails or fastenin gs are fed very nearly simultaneously with the feeding, forming, and fitting of the rand and delivered to the holes of the temthe drivers. The drivers are then immediately withdrawn, the nail-carrier moved backward to its original position, and the rand carrier and folding devices also returned to their normal position, the last or work-support lowered, the compression-plate moved inward by its cam, the last or work-support again elevated by its cam, and the outsoles caused to be compressed and formed to any desired extent.

To properly prepare the heel-seat for the reception of the heel-blank, it is desirable that the surface thereof should be flat or very nearly flat. Consequently, this pressure in most instances acts to force the edge of the outsole, the insole, and the rand downward upon the rounded edge of the last or worksupport, so as to bring the surface of the rand substantially level with the part of the sole within its inner edge. In other words, this compression molds the heel end of the soles andthe rand.

Attaching nails or fastenings of a length sufficient to extend through the outsole, counter, upper, and insole may be used, in

which case the heel end of theoutsole is notV attached to the insole by sewing or nailing until the attachment of the rand, when this section of lthe outsole is simultaneously secured-or fastened with the rand to the upper and to the insole.

I would say that substantially the same devices can be used for attaching welts to outsoles.
