HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 379,810, dated March 20, 1888.

Application filed January 3, 1888.

To all whom it may concern.-

Be it known that I, Fnnnnonn F. RAYMOND, 2d, of Newton, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Heel Compressing and Attaching Machines, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a machine organized to simultaneously compress one or two heel-blanks, and at the same time to attach a previously-compressed heelblank to the soles of the boot or shoe, or to prick it, or prick it and load it with nails, and it is illustrated as embodied in a machine having the characteristics of the National heelingmachine.

In the drawings, Figure 1 is aview, part in front elevation and part in vertical section, taken through the dies, to illustrate the features of my invention. Fig. 2 is a view, part in vertical section, from front to rear of the machine, and also showing some of the parts in elevation. Fig. 3 is a view, part in front elevation and part in vertical section, illustrating the position of the parts at the end of the downward movement of the cross-head. Fig. 4 is aplan view of the table supporting the dies, templet, and nail carrier. Fig. 5 is a view illustrating a change in the positions of the dies. Fig. 6 is a View of one form of die made in two parts, and Fig. 7 is a detail view of an adjustable former.

Referring to the drawings, A represents the cross-head of the machine. It is reciprocated preferably by means substantially as described in the Henderson patent, No. 816,894. It carries a head, B, which revolves thereon, and which has an arm, B, carrying agang or group of awls, B, an arm, 13*, a gang or group of drivers, B, an arm,B carrying a heel-spanker, B, which may have top-lift-holding devices attached. The eross-head also has the hunters C 0 arranged near each end thereof.

D is the bed of the machine. Upon it is mounted a post, D. This post D carries a table, D which has a vertical movement upon the post D in opposition to the stress of the coiled spring contained in the post and bearing against the table. The table D has the Serial No. 259,671. (No model.)

sleeve D, which surrounds the post, and it also has two forwardlyextending solid branches, D D". It also has the central way, D, in which the templet-plate D is adapted to be moved horizontallyinto and out of operative position, and upon the templet-plate there is arranged the nail carrier plate D which is secured thereto by cap-plates, and which is also adapted to be moved horizontally into and out of operative position. Each of the wings D D has a dovetail recess, 0, in its under surface,which receives the dovetail 0 upon the die-block that is, each die-block 0* is attached to its respective wing or support D or D by means of a dovetail. Each diebloek has a diecavity, C and a flaring mouth, 0, and is arranged over the spindle C, which carries a heel-seat former, O, and is vertically adjustable by means of the nut C in its supportingpost C There is formed in each of the arms D D a recess, 0, in which the lever 0 is vertically movable, and thislever is connected by means of the stud O with a plate, 0"", which is at the upper end of the die recess or cavity. This plate is adapted to be moved downward by the lever to remove the compressed heel-blank from the die. The table also has a recess, E, for holding a die, E. This die E (shown in Fig. 1) has a die-cavity a trifle larger than the cavities of the dies 0, and its object is to accurately center a compressed heel-blank while it is being attached to the soles of the boot or shoe.

E is a sliding jack which supports a last or work-support, E, upon which the boot or shoe is mounted, and the jack has a sliding movement upon the table D to bring the last or work-support beneath the die E and templet D In Fig. 5 I represent the dies 0* as sup ported by the bed D, instead of by the table D and the heel-seat formers (J are carried at the ends of the arms extending downward from the hunters O 0. On some accounts I prefer to use this construction, as it is cheaper than that first described. The dies 0, I prefer to form as shown in Fig. 6nan1ely, in the two parts 0 c. The part ccontains the die-cavity, and the part 0' forms the abutment upon which the plate 0 rests. The two parts are bolted together. This construction is cheaper than tion thereto.

where this is made in one piece, and allows the die-cavity to be more easily shaped.

In operation, a heel-blank is placed in the opening of each ofthe two forming-dies O, and

in contact with the surface of the outsole, and.

the machine is then caused to make one reciprocation, and this causes the heel-blanks to be compressed in their respective dies, and also the table to be locked down by the latch F in its lowest position. The awl 4 holes may be formed in the compressed. heel-blank at that time; or the templet may be moved downward by a pressure-block, F upon a fourth arm, F, of the revolving head. I prefer, however, that this arm be dispensed with, and that the awlholes be then formed. The nails are then fed to the templet-holes and driven by the drivers, which are brought into position while the heelblanks in the dies 0 are subjected to another blow from the cross-head.

If the attached heel-blankis to be spanked or a top lift applied thereto, the templet is moved downward, the top-lift spanker moved into position, the machinecaused to make another reciprocation, and in this event the heelblanks in the dies 0 receive another or third blow. The table D is then allowed to rise to itshighest position, and the jack is moved out from beneath the templet, and the boot or shoe moved therefrom and anoth erone substituted.

One of the compressed heels is then removed from its die-block and placed in the die E and an uncompressed heel-blank substituted for it in one of the forming-dies, and the operation of attaching the compressed heel-blank continues as before.

It will be seen that each heel-blank in its die G is thus submitted to four, six, or more blows from the erosshead before it is used, and that the heel-seat is formed before the blank is attached to the shoe. Of course it would be possible to use only one heel-forming die instead of two; but in the organization of themachine which I show I prefer to employ two, inorder to balance or equalize the strain upon the crosshead.

To prevent injury to the machine from an excess of pressure, I prefer to attach the crosshead A to the side rods by which it is reciprocated, substantially as shown in Fig. 5, where the rods are shown as connected with the crosshead by means of the interposed buffers M,

preferably of rubber, and confined in steel or other strong cylinders M and washers M which are contained in the cylinders and against which the nuts M upon the operating- 6 rods hear. The rubber buffers are compressed in the cylinders by means of nuts M and they are adapted to yield only for a pressure in excess of that used in the ordinary working of the machine for the purpose of preventing breakage.

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 ma chine, of the last or work-support and heel-attaching devices with one or more independent heel-forming dies, 0*, and heel-formers G arranged at the side of the heel-attaching devices and movable relatively to each other to compress one or more heel-blanks while a previously-compressed heel-blank is being attached to the soles of a boot or shoe, and a reciprocating cross-head, substantially as described.

2. The combination of the last or work support, the cross-head A, a rotary head carried thereby, having a gang or group of awls, a gang or group of drivers,and a top-lift spanker, or any two of them, adapted to be brought successively into the same operative position and reciprocated, the die or dies 0*, the former or formers G and the hunters O O, or either of them, substantially as described.

3. The combination, in a heel-attaching ma- 5 chine, of the vertically-movable table D its arms D D die-blocks Oflcarried thereby, the formers O", the templet D also carried by said table, the last or work-support E cross-head A, the nail-driving devices, and the hunters 100 G O, substantially as described.

4. The combination of the table D, the centering-die E, carried thereby, templet E, one or more dies, 0*, carried by said table, the formers G the nail-driving devices, and the 105 buntersC G, substantially as described.

5. The combination of the die 0, having the cavity 0 the plate 0, the spindle G ,and lever O substantially as described.

6. The combination, in a heel-attaching ma- I I0 chine, of nail-driving devices, a heel-blankcompressing die, 0 the heel-former O and means for moving one in relation to the other, and the heel-blank -centering die E, used in connection with the nail-driving devices, and hav- 1 1 5 ing a cavity slightly larger than the cavity of the heel-forming die 0 and the last or worksupport E substantially as described.
