To aZZ whom it Hwy concern:

Be it i; now u that l Fnnnnonn F. tiiyiuosn, 2d, of Newton, in the county 01' Middlesex and Statcof Massachusetts, a citizen of the United States, have invented a new and useful Iniprovement in Boot and Shoe Heel Forming and Attaching Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a partof this specification, in 8X- plaining its nature.

The invention relates to an organized heelnailing machine or heel-forming machine hav ing a die-block for forming the sides of the heel-blank, (either detached from the soles of the bootor shoe or while it is being attached to said soles,) sections of which die-block are made movable for the purpose of varying the size of the die.

It also relates to the said die-block and the parts thereof, and means whereby the adj ustments of its section are obtained.

In the drawings, Figure 1 is a view, part in elevation and part in vertical section, of the central and upper portions of a machine hav ing the features of my invention, the vertical section being taken upon the dotted lineyyof Fig. 2. Fig. 2 is a view in horizontal section upon the dotted line wot Fig. 1. Fig. 3 is a view partially in elevation, a die -block being broken out, to show the relation of the parts to each other during the forming or coinpressing of the heel-biank upon the soles of the boot or shoe. Fig. is a view, part in-elevation and part in vertical section, illustrating a slight modification. Figs. 5, (S, 7, and 8 also illustratemodified forms of a portion of the invention, to which reference will hereinafter be made. Fig. 9 is a plan view of the table supporting the teinplet and die.

Referring to the drawings, A represents the cross-head of the machine, which, preferably, is provided with a reciprocating movement, substantially as described in United States Patent No. 316,89 It supports a revolving head, (1, having, preferably, the arm a, which carries the presser-block a, the arm c supporting a block, a, carrying the awls a, arm (6, having a block, a, supporting the drivers (LS, and an arm, a having a spankenblock, c which may also have top-lift folding devices.

Bis the vertically-movable table which supports the die-block O, templet D, and the nail-carrier E. It has along sleeve, 0, which is mounted upon the post I). It has the extensions b, which support the die-block G, and the guideway b for the teniplct. The telnplet has a horizontal movement in this guideway, and with the nail-carrier E is secured to the bed by capplates If. The extensions 2) have side recesses, Zf, for holding the die-block, and the die-block. is fastened to these extensions beneath the templet by means of the springpin or in any other desirable way.

The die-block comprises the block 0, which is preferably shaped as represented in Fig. 1 that is, it has the recesses a, which receive the sections 0 0 of the die, the said recesses being formed with the shoulders a, the first ofwhich acts as a support for the flange o upon each of the two sections 0 o of the die, and the second of which acts as a support for the lower edge of these sections. (See Fig. 1.) These sections 0 c of the die are horizontally adjustable in said recesses c in relation to each other, whereby the width of the diecavity 0" may be varied as desired. This adjustment is obtained by i'neans of adjusting or setting screws c, of which there are prefer ably two upon each side of the die-block. These screws extend through screw-holes in the die-block, and their ends bear against the sections 0 a of the dies and form abutments or supports for holding the sections of the die in the die-block, and the width of the the cavity varies according as these screws are set in or out: This construction provides for the adjustment of the width of the die cavity or recess. For the adjustment of the length of the die cavity or recess I employ a diesection, 0*, the inner surface, 0, of which forms the front wall of the die-cavity. (See Fig. 2.) This section is formed of the metal plate, and is adjustable lengthwise the die-cavity to increase or diminish the length thereof by means i of the adjusting or setting screws 0, which pass through it into the block 0, (see Fig. 2;) and it will be seen that by changing the position of this plate 0" in relation to the die-block C the length of the die cavity or recess 0 is made variable. 1

"Where the heel-blank is molded upon the sole of the boot or shoe, it is desirable that the front section, 0, of the die be vertically movable during the compression of the heelblank, in order that it may not injure the outsole of the boot or shoe as the heel-blank is compressed and varied in height; and this fea ture of the invention may be used in a die otherwise solid, as represented in Figs. 5, 6, 7,.and 8, or in a die the length of which is adapted to be varied, as above specified. To accomplish it, the section which forms the front of the die is provided with a vertical movement in the vertical guideways c or recesscs formed in the die-block, as represented in Figs. 5 to 8, or in the movable section of the die-block, as represented in Fig. 2. This upward movement of the section 0 must be substantially unrestricted, and consequently the templet-plate must be so formed as to extend to the front edge of the die-cavity, as shown in Fig. 7; or, if it extends over it, it must have a recess into which the said vertically-movable section of the die-cavity can be moved. This section may drop to its normal condition,upon the removal of the compressed heel-blank, by gravity, or it may be returned thereto by means of the spring (I. (See Figs. 7 and 8.)

\Vhen the machine has a die having all the adjustments above described, the die is first set to the size of the completed heel which it is desired to form, and the heelblank is inserted in the die-cavity from below. The templet-plate is moved into position over the die-block and die-cavity, and the die-block and the templet are moved forcibly downward by the presser'block a upon a reciprocation of the head A, and the templet and die-block locked in their depressed condition. The pressure-block is then moved out of position and the awls into position and reciprocated, forming the holes in the hee1- blank. sition, the drivers brought into position, and nails conveyed to the holes of the templet by the nailcarrier, the reciprocation of the drivers driving the nails into the heel-blank and soles of the boot or shoe, if it is then desired to attach the heel-blank to the boot or shoe; and if the heelblank is to be blindnailed the templet and die are released, the heel-blank freed from the die, lthe templct withdrawn, and the spanker brought into position and provided with a top lift and reciprocated. I would say that by this means a die is provided which may be increased or varied in width only, or in length only, or both in widthand in length.

In Fig. 4 I show the die-block as made integral with the table B instead of separate from it, as represented in Fig. 1, and the diesections 0 c are made adjustable therein by screws 0, and the front plate, c is made hori- The awls are then moved out of pozontally adjustable in relation to the sections 0 0*;but instead of attaching it to the diebloclr or the equivalent therefor I prefer to attach it by its screws 0" to the face of the dieseotions c c".

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States-- 1. The combination, in a heel attaching or forming machine, of the templet, a die-block, and the die-sections c 0*, horizontally adjustable in relation to each other in the dieblook,

substantially as described.

2. In a heel attaching or forming machine, a-die-bloek and the die-sections c c", horizontally adjustable in the die-block, substantially as described.

3. In a heel attaching or forming machine, the combination of a die with a plate or block, a", a surface of which forms the breast end of the die and which is adjustable lengthwise the die for the purpose of increasing the length of the die, as and for the purposes described.

4. In a heel attaching and forming machine, a die having the verticallymovable breast plate or block,-as and for the purposes described.

5. In a heel attaching or forming machine, the combination of the die-block O, the sec tions 0 c of a-die supported thereby, and the adj ustingscrews c, substantially as described.-

6. The combination, in a heel attaching or forming machine, of the die-block having the shoulders 0 c, with the die sections 0 0*, having the flanges c and the screws c, substantially as described.

7. The combination, in a heel attaching or forming machine, of the die-block or die, the

plate or block c and the adjusting-screws c, substantially as described.

8. The combination, in a heel attaching or forming machine, of the die-block O, the diesections 0 0, their. adjusting screws c, the

breast plate or block 0 and their adjusting screws 0, substantially as described.

9. The combination, in a heel attaching or forming machine, of a vertically-movable table, a templet carried by the said table, a diebl-ock also supported by said table, a sectional die supported by said die-block and adjustable as to size, a support for the boot or shoe or heel blank, and a pressure-block, a gang of awls, and gang of drivers adapted to be brought successively into operative position and to be reciprocated, substantially as de scribed.
