SPECIFICATION forming part of Letters Patent No. 474,408, dated May 10, 1892. 4

Application tiled February 1l. 1889. Serial No. 299,513. (No model.)

.To al?, whom it may concern:

Be it known-that I, FREEBORN F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Rand Forming and Attaching Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention is an improvement upon that described in Vmy application for Letters Patent filed April 16, 1887, Serial No. 234,989; and it relates to various improvements in construction and organization, all of which will hereinafter be fully described.

Referring to the drawings, Figure l is a View principally in front elevation of the central and upper parts of a machine having the features of my invention. Fig. 2 is a view principally in vertical section of the central and upper parts of said machine, taken from front to back. Fig. is a view principally in plan upon a line immediately above the surface of the fastening-carrier. Fig. 4 is a view in plan reversed of a portion ofthe mechanism, to which reference will hereinafter be made. Fig. 5 is a view in plan of parts of the operative mechanism, to which reference will hereinafter be made. Fig. 6 is a view in perspective of the templet and former. Fig. 7 is a view in vertical section thereof. Fig. S is a cross vertical section taken through the nail or fastening carrier. Fig. 9 is a view in perspective of a randed shoe. Fig. 10 is sectional detail.

A represents the frame of the machine; a, a sliding jack having a horizontal sliding movement in suitable ways upon the bed a.

'A' is a cross-head,which is provided with a reciprocating movement, substantially as specified in Patent No. 316,80l, and which bears or carries a head A2, which has any arm a2, carrying a gang or group of awls a3, and an arm CL4, carrying a gang or group of drivers a5. The head is attached by the shaft d6 to the cross-head A', and is adapted to be oscillated or turned to bring the awls and drivers alternately into operative position. In Fig. l the drivers are represented in such position.

3 is the templet.l (Sec Figs. '1, 2, 6, and 7.) It is represented as detachably secured to the table C, having side ribs which extend into horizontal grooves or recesses formed in the sections c of the table C. (See Fig. l.) The templet is secured in place by a spring-pin or in any other desired way. It has the holes b, through which the fastenings are driven, and in the drawings they are represented as long horizontally or from side to side to receive a staple-fastener. The templet-block supports a rand-former B', which comprises a block b2 of metal set in a recess b3, extending upward from the under surface of the templet and attached thereto by pins or studs b4 (see Fig. 2) in a manner to have a vertical yielding movement in relation to the templet, a spring b5 forcing it downward from the templet, so that a section b of its side immediately adjacent to its lower edge is caused to be normally below the under surface?)7 of the templet. (See Figs. 2 and 7.) The blocks b2 is of a shape upon its section o to provide a former, againstwhich the edge of the rand shall be brought in contact as it is fitted to the heel end of the outsole of the boot or shoe to which it is to be attached. The under surface bs of the formerblock may be made slightly concave, if desired. The surface 57 of the templetsurrounding the former-block preferably is level or flat, and it serves to flatten down, consolidate, and shape by vertical pressure the rand upon the outsole and also the rand, outsole, upper edge, counter-edge, and insole in relation to the bottom of the last or heel support.

To form or shape the rand about the randforiner B', the templet is moved downward by depressing the table O by means of the lever c' and link c2 sufficiently to bring the under surface of the rand-former upon the upper surface of the outsole. A forming-strap D is caused to be moved horizontally against the outer edge of the rand and in a forward direction in relation to the templet and randformer block, whereby the rand is caused to be folded or turned about the edge of the block in the cavity or space between the under surface 57 of the templet and the upper surface of the outsole.

The forming-strap D preferably is a steel tape in one piece, each end d of which is coufined in a long tube CZ', (see Figs. 3 and 5,) in which it is movable lengthwise the tube in opposition to the long coil-spring d2. These IOO tubes are secured to the under surface of a slide d3, to be horizontally lnovable therewith, and the steel tape extends from the front ends of these tubes about the rolls (Z4 d5, carried at the forward ends of the levers dcil, respectively. The lever d is pivoted at d8 to the under surface of the slide d3 and the lever C17 is pivoted at (Z9 to the under surface of said slide, and the two levers are drawn toward each other by means of a spring d10, (see Fig. 4,) and the extent of their closing movement or the movement of the rolls toward each other may be limited by the rod d, also fastened to the under surface of the slide and bearing-nuts, and one end of which extends through a hole in a lug dit?, formed on the lever CF, and the other end through a hole formed in the lug C113 on the lever d,

' The ends of the rod are screw-threaded and receive the nuts du. The rolls d d5 are always set to be open or separated slightly from each other, and the tape or forming-strap D passes around the front edge of each and across the opening-between the two. The slide cl3 also has the nail or fastening carrier E, which preferably is secured thereto to be removable therefrom, and which has the holes e for receiving the fastenings, which holes are represented as closed bymeans of the slideplates e e2, the two plates being drawn toward each other upon the under surface of the nail-carrier by a spring es to close theholes and being automatically separated to open them when the carrier has been moved into position over the templet by means of the wedge e4, (see Fig. 6,) against the sides of which the edges e5 e6 of the front part of the said slide-plates e e2 are brought in contact. The slide-plate d3 also supports or carriesthe levers ff,which are pivoted at dsd, respectively, to the slide cl3, and they carry at their forward ends the rand-supports F F, respectively. (See Fig.5.) rlheserand-supports preferably are made vertically adjustable in relation to the ends of their supporting-levers, and this vertical adjustment is represented as obtained by means of a pin or stud f2, upon which the supports F F have a horizontal partially turning` or swinging movement, and the set-screws f3, the studs or pins f2 entering the holes in the ends of their respective levers, and the set-screws locking the studs at any desired elevation thereto, the supports F F, as above said, being free to rotate or turn upon the pins.

The randsupports F F preferably are shaped substantially as represented in Fig. -that is, each has a curved edge f upon the side next the roll and a rounded or curved end f5 toward the shoe, the said end f5 preferably having a downward e2 tension or lip f6 to bear against the edge of the outsole. The supports are held to their respective levers so that the points or sections f7 extend inward and against the edge of the roll, but in a manner to yield, and this result is obtained by means of the spring f8, which attaches the inner end f'7 of the support to its supportinglever. (See Fig. 4.) This permits each of the supports F F to move in relation tothe rolls or tape-supports d4 d5, andthe heel of the boot or shoe to follow or rather to move in advance along each edge of the shoe from the heel end thereof of'the rand which they support and which is being formed about the former by the strap ortape D, which is caused to conform to the shape of the former, as Well as to the shape of the edge of the sole at the heel end by the rolls d4 d5. These supports F F are also made vertically adjustable upon their respective levers to vary the height of their upper surface, upon which the rand rests, and also their level in relation to the level of the upper surface of the outsole. A thick rand demands that the supports be moved downward and a thin rand that they he moved upward. This vertical adjustment is represented as obtained by means of a pin f2 and the set-screws f3, as above specified.

The extent of inward movement of the supports F F and the lever ends in relation to the rolls is adjusted or regulated by the set-screws 9 see Fifn these set-screws actingavainst f 7 D J b projections extending downward from the roll-levers, which in Fig. 5 are represented as screws. The tape D preferably is of a width sufficient to lap upon the edge of the outsole and to extend above it to the under surface of the templet-plate, and the rolls (Z4 d5 are of a width sufficient to properly carry said tape. This permits the same tape to be used for all thicknesses of rands, and the under edge or lower part of said tape preferably extends below the surface of the rand-supports F F.

As heels vary in width, it is desirable that the rolls d4 d5 and the rand-supports be made adjustable in relation to each other, so that for the narrower heels the rolls may be located before they are moved upon the edge of the sole sufficiently close to each other and that for the wider heels they may be moved farther apart. Y It is also desirable that they should be held at such a position in relation to each other that they will move on the sole-edge from a point at each rear corner of the sole, and from that point to be held against the edge of the sole by yielding pressure. These results are obtained by carrying upon the backward-extending sections c3 c4 of the table C the horizontally-adjustable leverholders G G. Each lever-holder is represented as an anti-friction roll and as mounted upon a slide-block g, which slide-block. is horizontally movable upon the lower surface of its respective holding-arm by the screw-A IOO IIO

are held by these holders until the rolls are moved forward, when the ends gG clear the holders and permit the sprin g d10. to hold the rolls together and upon the sole-edge; but by setting the holders toward each other by means of their adj Listing-screws the rolls d" d5 are caused to be moved farther apart, and by moving them from each other the rolls are caused to be held nearer each other.

ltis desirable that the levers come in contact with the holding-blocks upon their backward movement, and also of the rolls or tape supports and the slide which carries them immediately upon the rolls leaving the heel end of the sole, the heel end of the sole acting to hold the rolls in a position to permit the ends of the levers to enter the space between the two holders, and on the other hand, upon the forward movement of the slide, rolls, and leversthe holders act to keep the rolls separated from each other sufficiently to close upon the edge of the heel and until they are in a position to close upon said edge,.so that for the remainder of their forward movement they are held separated by the sole. 4

The operation of the machine is substantially as follows: The rand is placed upon the rand-supports in front of the rolls and tape when they are in their back position. The shoe is mounted upon the last or work support and moved under the rand-former` and ten1plet-plate,the heel end of the outsole preferably not being permanently attached to the insole. The templet and rand-former are then moved downwardly until the under surface of the rand-former comes in contact with the upper surface of the sole, when the rand is moved toward the rand-former bythe movement of the slide cl3. This movement of the slide causes the inner edge of the rand at about the center of its length to come in contact with the rear end or surface of the former, and the rand is fitted to the outsole by forming or turning it from its center toward each end about each side of the former, the former governing the location of the inner edge of the rand upon the sole and the tape or strap governing the relation which its upper edge bears to the edge of the sole. If the former is of suitable size and the rand of suitable width, then the outer or thick edge of the rand is brought flush with the edge of the outsole. If the rand and outsole are to be pricked before the attaching fastenings are driven, then the awls are caused to make a reciprocation.

In the operation of the machine, the templet and rand-former having been moved downward by the hand-lever upon the work and the rand having been formed about the former, the drivers act to drive the fastenings through the holes of the templet into the rand and work, and the surface of the driver-holding block also acts to communicate to the tem piet, at the end of its downward movement a pressure or blow, whereby the rand is flattened forcibly upon the work, and, if desired, the outsole beaten out or formed to the surface of' the work-support or last.

For certain kinds of work the drivers may be dispensed with and the templet be imperforate, and the rand in such case is secured to the outsole by glue or cement applied to the under surface of the rand or to the upper surface of the sole. The templet then acts as a pressure-block for setting or pressing the rand upon the sole.

I prefer that the table C have side extensions 7L h', by which it is mounted upon the side rods h2 7a3, which operate the cross-head A', the table being secured to said rods by the boxes h4, (see Fig. 1,) which are bolted to the side extensions h h', and the table is moved downward in opposition to the springs h5,

which rest upon the bed a and bear against the under surface of each of the side extensions h h. The table also has the angle crosspiece or connection h6. (See Figs. 1 and 2.) The table is also provided with the wide opening hi, (see Figs. l and 2,) which opening extends upward upon each side of the templet and rand-forming devices to form the sections hs. The front edge hg of the upper part of the table extends forward from the remainder of the table, the upper sections h1@ of the table extending upwardly from these advanced or forward sections and also downwardly. (See Fig. 2.) Bythus construct ing the table a sufficient support is provided the templet B and the rand-forrning block, while the other rand-forming devices are so exposed or situated that the rand can easily be mountedrupon the rand-supports while they are in their back position or that represented in Figs. 2 and 3. The cavity or opening 71.7 extends entirely through the table. (See Fig. 2.) The fastening-carrier and the the rand-forming devices are mounted upon the same slide, and the slide is represented as moved horizontally in the table C by means of the lever M, which is pivoted at m and which is connected with the slide by means of the hanger mthe link m2, connecting the end of the lever with the hanger, and the link m3, connecting the end of the hanger m with the lugs m4, extending downward from the slide. (See Fig. 2.)
