HEEL-HOLDER FOR HEEL-ATTACHING MACHINES.

SPECIFICATION forming part of Letters Patent No. 699,1 13, dated April 29, 1902.

Application filed July 18, 1898.

To all whom it may concern:

Be it known that I, FREEBORN F. RAYMOND, 2d, a citizen of the United States, and a resi-- dent of Newton, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Heel-Holders for Heel-Attaching Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying IO drawings, forminga part of this specification, in explaining its nature. I The invention relates to a device for holding the heels centrally during the nail-driving operation, also to a particular form of nail-driving device, and also to the combination of the heel-holder with nail-driving devices.

Referring to the drawings, Figure 1 represents in vertical section a rotary nailing-head 2 v having two heel holding and nailing devices thereon, one of which is shown in operative conjunction with a portion of a jack to repre sent the relation which the heel-holderbears to the heel of the boot or shoe at the instant of attachment. Fig. 2' is a plan view of the rotary head and heel-holder. Fig. 3 is a view representing in section a heel-holder and a nail-driving plate in connection therewith for use when the heel is to be blind-nailed in- 36 stead of flush-nailed. Fig. 4 is a View, partly in plan and partly in section, of the holder and nail-driver of Fig. 3. Fig. 5 is a View in section, representing theconstruction shown in Figs. 3 or 4, which will hereinafter be specified. Fig. 6 is a View in plan of the top-lift holder used in connection with the rotary head of Fig. 1 upon two of its arms. Fig. 7 represents the same construction of holder as that shown in Fig. 1, the nailing-plate being attached to the arm of the rotary head in a different manner. Fig. 8 is a view in vertical section, representing a modified form of holder,to which reference is hereinafter made. a is the rotary head. a represents the arms carrying the nailingplates and heel-holders; of, the arms carrying the top-lift holders and spankers (1 The heel-holder 1) preferably is given the vertical or sliding movement in relation to the nailing-plate b and arm a and when so Serial No. 686,241. (No model.)

constructed is shaped to fit the outer edge I) of the nailing-plate to slide thereon and be guided thereby. It is moved outward to maintain its opening 17 in positionto receive and locate the heel-blank preferably by spring b and the extent of its outward movement is limited by a stud b to the end 19 of a slot 12 in the holder through which the stud extends. The holder preferably has the mouth or opening e' of a shape to bear against the sides or portions of the sides and the back of the heel and is varied as to shape, as the heels vary in this particular. The front 6 of the holder preferably is open. Then'ear portion of the holder, or that section which slides upon the plate b, preferably has the cross-bar b and this preferably is integral with the rest of the holder. The holder has sufficient movement in relation to thesurface of thenailing-plate to permit a loaded heel-blank to be placed therein and held byits sides without the ends or heads of the attaching-nails coming into contact with the attaching-plate, the heel being held in the heel-holder by the contact of its side and back surface or sections thereof with the bearing-sections of the holder. By providing the holder with the front opening ethe heel-blank may be more quickly and readily placed in position.

The nailing-plate b mayhave a flat nailing-surface c, as represented in Fig. 1, or it may have a groove or recess (Z, as represented in Figs. 3, 4:, and 5. The fiat surface is adapted for flush-nailing and the grooved surface for blind-nailing. The groove isfmade of the shape in which the nails are arranged or located in the heel, preferably continuously in the plate, and of a depth to receive the sections of the heads or ends of the nails, so that they may not be driven flush with the surface of the heel-blank, but may, after the at tachment of the heel-blank, project fromthe heel-blank sufficiently to receive and hold the top lift. To insure wear, I-preferto cover the plate I) with a thinsteel plate and in'the plate represented in Figs. 3 and 4 to make the groove deep enough to receive and hold a removable steel wearing-piece of'a Width to fit the recess cl.

In order that the nailing-plate and holder may be readily removable from its holdingarm a and also in order that the arm a may receive a nailing-plate and holder for any size heel, I make the arm a of a size sufficient to receive the smallest nailing-plate, and instead of attaching the nailing-plate to the arm a by a dovetail, as represented in Fig. 1, I provide it with a spindle f, which enters a hole in the arm a of a size to'receive it, and the spindle is locked to the arm a by a set or locking screw f. This enables the nailingplate and holder of one form to be quickly removed and one of another form substituted.

It will be seen that this device aifords a quick, ready, and accurate means of placing a heel-blank in position for attachment and also serves to accurately center the heel-blank during the attachment, also holds the heelblank in place during the movement or rotation of the arms a from one position to another, also does away with the necessity of placing the ends of the nails in the holes of a templet, as when drivers are employed instead of a nailing-plate.

The rotary head is preferably mounted upon a horizontal axis and may be moved vertically by a reciprocating cross-head or may be stationarily held. In the first event the jack will be stationary and the rotary head movable toward it to attach a heel-blank and top lift. In the second event the jack will be movable toward the rotary head during the attachment of the heel and the top lift. By mounting the head upon a horizontal axis the heel-holders and top-lift holders are adapted to be supplied with heels and top lifts when in their uppermost position and to attach them when in their inverted or lowermost position. This enables the heel-blanks and top lifts to be quickly placed, and with their holders in sight of the boy or operator who feeds the heel-blanks and top lifts. The rotary head may have but one heel-blank holding and nailing device and one top-liftapplying device, in which event I prefer that they be arranged diametrically opposite each other.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- 1. In a heel-attaching machine the combination of nail-driving devices movable from an overhead receiving to an underneath attaching position, with a heel-holder provided with fixed sides forming a socket to hold the heel and movable with said nail-driving devices from receiving to attaching position and also movable toward and from the nail-driving devices.

2. In a heel-attaching machine, the combination of the nail-driving device with a heelholder attached thereto and movable lengthwise thereon, said heel-holder being hollow and having a section at its outer end, of a shape corresponding with the shape of the sides of a heel-blank and forming a socket to receive and hold the heel-blank in a position removed from the nail-driving devices, and a section forming a sleeve having parallel sides, said sleeve being the shape and area in crosssection of said nail-driving device and adapted to slide thereupon, said sections forming a continuation of each other, as and for the purposes set forth.

3. In a heel-attaching machine, a heel-attaching arm or support and a heel-holder adapted to slide telescopically upon it, said holder being hollow and having a section shaped to receive and support a heel-blank by its edge and a section having sides parallel with those of said arm or support whereby said holder is adapted to hold a heel-blank in a position somewhat removed from the end of said arm or support and to permit the movement of the arm or support relatively to the holder and the heel-blank in the act of attaching it.

at. In a heel-attaching machine, a heel-attaching arm having a hollow heel-holder slidably attached to its outer end, said heelholder having a section forming a sleeve with parallel sides adapted to slide on said arm, and an outer enlarging section shaped to receive the sloping sides of a heel, and limit the entrance of the heel-blank therein, whereby each blank will be held in a predetermined position with relation to the shoe during the heel-attaching operation, as set forth.

5. In a heel-attaching machine a plate having a continuous recess (Z adapted to receive the heads of nails projecting from aheel and serve as a driver therefor, in combination with means for holding the heel during the driving operation.

6. In aheel-attaching machine the plate having a continuous recess d adapted to receive the heads of nails projecting from a heel to be attached, in combination with a removable FREEBORN F. RAYMOND, 2D.
