To all whom it may concern.-

Be it known that I, FREEBORN F. RAYMOND, 2d, a citizen of the United States, residing at Newton,in the county of Middlesex and State of Massachusetts, haveinvented a new and useful Improvement in Heel Compressing and Loading Machines, ofwhich the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part vof this specification, in explaining its nature. 1

The invention relates to an apparatus for compressing and loading heel-blanks comprising the rotary cylinder carrying one or more compressing-dies and former for each' die movable in relation to its cavity by means of a suitably shaped bearing abutment, against which the former is brought in con-. tact as the die is rotated; also to an arrange ment within thecylinder carrying the dieblocks or apparatus for pricking holes in the heel-blank from the die.

It further relates to various details ofconstruction and organization, all of which will hereinafter be described.

In the drawings, Figure 1 is a view in front elevation of the central and upper parts of the machine. Fig; 2 is a vertical section-0f the said central and upper parts of the ma chine, taken from side to side thereof. Fig. 3 is a view in elevation of one side of the cen- 'tral and upper parts of the machine. .Fig. 4-

is a vertical section thereof taken from front to back of the machine.

A is the base of the machine. a, is the shaft to which preferably power is communicated. 1

B is a cylinder provided with bearings 1) upon the brackets b 19 which brackets are" bolted to the bed of the base and have inwardextending circular sections b which serveas bearing pieces or trunnions upon which the cylinder B is rotated. The cylinder has the cavity 0, and across this cavity there extends a shaft 0, which has bearings in the brackets b b at o 0 and which carries a cam c for operating the gang of awlsc the gang of driV-' ers c and the ejector c". The shaft 0 is ro-j tated by means of the gear c upon one end thereof, the intermediate gear 0 and the gear 0 upon the shaft a.

The cylinder B isrepresented as carrying the four die-blocks D, each of which has the die-cavity d and the perforations d, through which the awls, nails, and drivers are moved, and the hole d through which the ejector 0 passes in throwing the loaded heel-blank from the die. These die-blocks, are fastened in re cesses or holes formed in the cylinder in any desired way, and; there is attached to the cylinder, to be rotated with it, a former E for each die-block. This former is removably secured to a former-carriage E, which comprises a block e carrying an antifriction-roll e, and preferably secured to the cylinder by means of a link e pivoted at e to a log efl and connected by a pivot c with the block e. The block has bearings e for the shaft of the roll e'l (See Fig. 2.)

F is the pressure-applying plate or abutment. It is secured to the base of the machine and has a surface f which is placed eccentrically in relation to the circle or path upon which the outer edge of the cylinder 13 rotates to cause the former-carriage E and the formers to be moved gradually inward as they travel or move in relation to the same, the, rolls 6 of course bearing against. the said surface 7 in successive order. The awls c .are mounted upon a block 0 which is re- This slide is arranged tobe reciprocated in a suitable bearin g-hole in the cross-plate e by means of the cam-groove c? in the cam-disk 0 The slide also has a bearing upon the shaft 0, the end of the slide being foiimed as a yoke to straddle the shaft. The-drivers c are also re movably secured to a slide cf. This is also reciprocated by the cam-groove 6 and, like the slide 0, it has a yoke which straddles the shaft 0. The slide 0 also has a bearing in the cross-plate 0 The ejector is mounted upon a slide-block and is moved by the cam projection c outwardly, and is returned by the spring 0 Nails are fed v to the holes or perforations of the die by means of the nail-carrier G, which is automatically moved through the hole g in the bracket 1) to a po sition to deliver nails beneath the driver and into the holes of the die-block,which shall then ICO be beneath it. h It may be automatically moved in any desired way, and I have represented arm g the right-angle lever g pivoted at g and connected at its upper end by means of a stud g with a slotted hanger 9 attached to the plate g carrying the nail-carrier. The nail-carrier is supplied automatically with nails from the nail-supplying apparatus H, which preferably consists essentially of these elements: A number of pairs of nail pointing and severing rolls I-l; wire-feeding rolls h, adapted to feed a number of Wires and to make simultaneously, or practically simultaneously, a nail from the end of each wire; a nail-receiving block 7t, which is automatically moved to bring its holes in register with the throats through which the nails are delivered from the rolls, and which is automatically returned to deliver its nails to the distributer I1 and the said distributor adapted to receive the nails from the nail-receiving block and to deliver them to a nail-carrier. These features are described in an application for Letters Patent of the United States of even date herewith, and I would say I prefer to use this form of automatic nail-supplying device because, by making nails from a number of wires, 1 am enabled to produce a large number very quickly, substantially as quickly as they are needed for use in the machine. I would not be understood, however, as limiting myself to this particular form of nail-supplying mechanism.

Each former-carriage E preferably has in addition to the roll 6 a roll m attached to one end of the shaft of the roll a and which serves in connection with a side guide M extending from the point 712 to the point m (see Fig. 4) to hold the former and former-carriage open or awayfrom the die during the movement of each die from its lowest position to very nearly its highest position, so that the die is open or uncovered automatically both to permit the loaded heel-blank to be ejected therefrom and also the insertion of a new blank to be formed and loaded.

The machine preferably is organized to stop at each quarter-revolution ofthe die-cylinder. The cylinder is represented as alternately rotated and brought to rest by meansof a feedpawl N, mounted upon the lever n, which is pivoted upon the shaft 0, the crank 71/, and

the connecting-rod 01 the crank imparting to the lever an oscillating or reciprocating movement, first causing the pawl 91 to engage with one of the four notches n in the side of the cylinder and then moving it forward a quarter of a revolution, so that for every full revolution of the crank 71' the diecylinder is moved a quarter-revolution in half the time of the revolution of the crank and is at rest for the remainder of the time. I would say that I do not confine myself to this particular mechanism for rotating the cylinder but may use any mechanical equivalent therefor.

In operation the heel-blanks are placed in thedies in successive order, and upon the rotation of the cylinder the former is caused to be moved forcibly against one end of the same by the movement of the cylinder in relation to what may be called the curve compressing Wedge or cam f, and this movement of the dies to secure the compression of the heelblanks brings each compressed heel-blank in turn in line with the gang of awls and with the nail-loading devices, and each heel-blank is first submitted to the operation of the awls 0 which while the die-cylinder is at rest makes a rapid movement through the holes in the die-block and pricks the heel-blank while it is under compression. The cylinder is then moved, bringing the compressed but unpricked blank in line with the awls, while the compressed and pricked blank is moved into positionto be loaded, and the cylinder coming to rest the awls operate to form the holes in one blank while the drivers are actu ated to drive the attaching-nails into another blank. The nails have previously been automatically fed by the nail-carrier into a position beneath the drivers. A further rotation of the cylinder causes the heel-former to be released from the die and to be automatically removed from it to open the die and bring a loaded heel-blank before the ejector, a pricked and compressed heel-blank beneath the drivers, and a compressed heel-blank in line with the awls, and at the next operation of the machine a loaded heel-blank is ejected from the die, a compressed and pricked heel-blank is automatically loaded, and a compressed heelblank pricked.

It will be observed that the pressure upon the heel-blank from the first action of the former during the prickingjby the awls'and the loading by the drivers is continuous, and that it may be varied 'as to intensity by varying the inclination or relation of the wedge or cam surfacef in relation to the cylinder; that this produces a very powerful and slow and continuous compression which produces a Very-nicely compressed heel-blank. It will be observed, further, that the awls and drivers are worked from the interior of the diecarrying cylinder.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1.
