HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 599,012, dated February 15, 1898.

Application filed August 17, 1889, Serial No. 321,157- (No model.) I

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, have invented a new and useful Improvement in Heel Nailing 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 relates to a heel-nailing machine having novel delivery mechanisms or devices for feeding heel-blanks, top lifts, and nails into operative position. It is desirable in certain organizations of machines to place the top lift, heel-blank, and nails in their re-' spective holding devices at the front of the machine at one side of theoperator or point at which the heel-blank, top lift, and nails are used in the attachment of the top lift and heel-blank to the boot or shoe, and I shall herein describe means for carrying these movements into effect.

Referring to the drawings, Figure 1 is a view 2 5 in front elevation of the central portions of a nailing-machine having the features of my invention. Fig. 2 is a View, principally in plan, of the principal parts of the mechanism shown in Fig. 1. Fig. 3 is a view in vertical o central section thereof. Figs. 4, 5, 6, and 7 are detail views, enlarged, to which reference is hereinafter made. Fig. 8 is a view of the heel-blank and top-lift carriers inverted. Fig. 9 is a detail view illustratinga slight modifi- 3 5 cation, and Fig. 10 is a view showing the toplift holder and spanker.

The invention is represented as applied to the machines having the organization shown and described in my Patent No. 377,577, dated February 7, 1888, in which the templet is preferably stationary and the last or work-support is mounted upon a spindle forming a part of the jack and provided with vertical movement 7 by means of a pressure-head and cam, the va- 5 rious nailing devices being carried by a revolving head mounted upon the cross-head and preferably automatically operated.

In the drawings, A represents the templet. It is supported by the upper table a and is detachable therefrom. 7

B, Fig. 1, represents one of the arms of the revolving head, and B the gang of drivers carried thereby.

C is a vertical shaft at the rear of the ma- 7 chineto connect with the driving-shaft. (Not shown.) Upon it are mounted various operative cams to operate or move theheel-blank carrier 0, the top-lift carrier 0, and the nail carriers 0 0 The heel-blank carrier 0 has any suitable form of heel-holding device 0 I prefer the form represented in Fig. 8, comprising the two arms 0 c pivoted, respectively, at o c to a support 0 the inner ends of which arms are formed with segment-gears 7 0 which mesh with each other, and the outer ends of which arms are provided with inwardextending shoulders o and flaring ends 0 one or more sprin gs 0 to hold said arms closed, and a V-shaped slide-plate 0, carried by said support 0 arranged to slide therein and held in operative position by a spring 0 the spring acting to continuously press the V-guide toward the shoulders 0 This causes the heelblank to be held with its breast in contact with the shoulders c by the pressure of the V-piece upon the rear of the heel. It enables heels of any length and width to be taken. It also permits them to. be moved horizontally into place.

The plate 0 to which the arms 0 c are attached, is secured or formed upon the front end of the heel-blank carrier, and the carrier comprises, in addition to this holding-plate and the heel-holder, a long plate or arm 0 pivoted at c -on'one side of the machine and having at its rear end a cam-pin 0 which enters a cam-groove 0 in the cam-disk upon the vertical shaft C. The topdift carrier 0 comprises a steel plate d and a top-lift .holder (2, and I prefer the form of holder rep- 9o resented in Figs. 5, 6, and 7, which is practically like the heel-holder in construction, with the exception that the shoulders (1 the equivalent of the shoulders o of the heel-holder,

are represented as movable lengthwise their 5 supporting-fingers, so that their position may be varied sufificiently to provide for the endwise adjustment of the top lift in relation to the holes or pricking of the templet. It is quite desirable in order that the same templet I00 may be used for two or more. sizes of heels that the top-lift holder have this provision for adjustment of the top lift back and forth or from breast to rear to change the relation or position of the top lift in regard to the holes or pricking of the templet, as by such adj ustment the same templet and nailing devices may be used for attaching heel-blanks varying quite materially in size and the top lifts be varied as to size to correspond. This toplift plate (Z is formed upon or attached to the arm or lever 61?, which extends backward, is pivoted at d to the under surface of the table a, and has at its rear end a cam-pin 61 which enters the cam-groove d in the camdisk 0 The nail-carrier c is detachable from its holding plate or lever e. This plate or lever extends backward and is pivoted at e to the upper surface of the table a and carries at its end a cam-pin 6 which enters the cam-groove e in the cam-disk e on the vertical shaft 0. The nail-carrier c is also detachable from its nail-carrying plate or lever f. This plate or lever extends backward, is pivoted at f to the upper surface of the table a, and has at its rear end a cam-pin f which enters the cam-groove f in the under surface of the cam e. The two nail-carriers c c are used when it is desirable to provide the templet A with two sets of nails, either attaching-nails and slugs or sole-nails and slugs, or two gangs of attaching-nails or two gangs of slugs, as the case may be. It will be observed that the heel-blank carrier, top-lift carrier, and nailcarriers are connected directly with their operative cams and that these devices or delivery mechanisms are moved upon arcs of circles outward and forward from the templet A to a position upon each side of the templet and also so that they are inclined away from the templet and are favorably situated for the placing of the heel-blank and top lift and the loading of the nail-carriers either automatically or by hand. The cams preferably are timed to move the carriers as follows: First,

the cams for operating the heel-blank carrier and nail-carrier o to move the heel-blank into operative position beneath the templet A, and at the same time or immediately following the nail-carrier 0 into position over the templet A, and then to simultaneously return the heelblank carrier and nail-carrier to their original position,and to hold them in such position during the continued operation of the machine; second, the cam for operating the top-lift carrier is timed to hold the carrier out of position during the attaching of the heel-blank, and to then move it into position beneath the templet, and to hold it there during the spanking of the top lift to the attached heel, and to then return it to its original position and hold it in such position, and, third, the cam for operating the nail or slug carrier 0 to hold it out of operative position until the top lift is moved beneath the templet, and to then move it into position to deliver its nails or slugs to the proper holes in the templet, and to hold it during the driving of said nails or slugs, and to then return it to its original position and hold it in said position. top-lift carrier only need be used, for other kinds the top-liftcarrier and the nail-carrier 0 for yet other kinds the heel-blank carrier, top-lift carrier, and nail-carrier c and for other kinds the heel-blank and top-lift carriers and the two nail-carriers. When two sets of nails are to be driven into the heel, the templet A is provided with two lines of holes I) b, and if the nails are also driven through the top lift the top-lift spanker-plate d is provided with the holes 19 I have represented in Figs. 4 and 5 the toplift spanker-plate and top-lift holder as provided with various adjustments for the purpose of varying the position of the top lift in relation to the templet. I would also say that the same adjustments, or such of them as are desirable, may be used in connection with the plates or levers for holding the heelblank holder and the two nail-carriers. By making the lever or plate (Z in the two parts 9 g, as represented in Fig. 5, and by attaching the part g, which carries the toplift spanker-plate and holder, to the part g by means of a pivot the angle of the plate and holder in relation to the vertical median line of the templetA maybe varied to any desired extent, and the section 9 is locked in anyposition to which it may be moved for the purpose of obtaining such adjustment by means of the set-screws g carried by lugs 9 one on each side of the plate 9 and adapted to be set against each edge of the section g.

By making the hole through which the pivot 9 passes either rectangular lengthwise the lever and either in the section g or in the section g, or both, as may be preferred, the toplift spanker-plate and holder are provided with an adjustment lengthwise the templet A to vary its position by a forward or backward movement in relation to it. By making the top-lift spanker-plate 01 separate from the section g or from the end of the lever d and providing in the front edge of said section g a horizontal dovetail recess ,which receives a horizontal dovetail tongue g upon the inner edge of the said top-lift plate, the top-lift plate and holder are provided with a movement crosswise the templet A, or from side to side, and to limit and control said movement set-screws g passing through appropriate lugs or holders to secure them to the section 9, bear against each end of the dovetail tongue 9 of the plate. The breast-shoulders d are made adjustable lengthwise the arms of the top-lift holder in any desired way. I have represented two of these ways.

In Fig. 7 I have shown the shoulders as formed by the ends of screws h, which we tend from the front end of each arm to bring their inner ends d in line with the edge h,

For certain kinds of work the I l. l 1 l I .whereby the screwupon being moved in or out maintains substantially the angle of the edge h, and its point 01 forms the shoulder.

In Fig. 6 I have represented each shoulder 01 as formed upon a slide piece or block W, secured to the end of its respective arm by a dovetail 71 upon the block or piece h? and a dovetail recess 7%, formed in the side of the finger and receiving the dovetail tongue. The piece 71 has a bent end hithrough which an adj usting-screw it passes into the end of the arm or finger and by means of which the piece or block IL2 is made movable on the finger and the location of the shoulder 01 varied. I prefer that the arms of the heel-holder be provided with similar adjustable breastshoulders, and also that in addition to the shoulders the arms of the holder at a point adjacent to the shoulders be shaped as represented in the figures, so that in addition to the breast-gage there is also a side gage or surface of limited extent, whereby upon the closing'of the fingers by their operative spring and the pushing forward of the top lift or heelblank by the back holder the heel or top lift is held with its breast against the shoulders, while the gages 7c are pressed against the sides of the blank or top lift near the breast.

(See Fig. 7.) It is desirable that the springs operating the back slide-plate and-the fingers of the holder be so proportioned that the top lift or heel-blank will be pressed forward against the breastgages, while the fingers shall close sufficiently to bring the said gages 7t in contact with the sides of the top lift or heel-blank. I would say, however, that in many instances the side gages k may be dispensed with.

In Fig. 9 I have represented a construction which varies somewhat from that shown in the other figures in that the arm or lever o which is shown as a top-lift-carrier arm or lever, but which is a type of all the arms or levers used for the various holders, is pivoted at its rear end (Z while the cam-pin d engages the cam-groove in cam e at the proper distance from said end. This ofcourse makes the lever or arm longer, but it also permits a very easily-constructed cam tobe used.

It will be seen that the top-lift spankerplate cl, Fig. 8, extends outward beyond the breast-shoulder d and that there is an opening or space between the ends of the fingers d. This construction provides a guide for directing thetop lift orheel-blank as it is placed in the holder, both the opposing edges of the projecting ends of the holder and the under surface of that portion of the spanker-plate which projects in front of the breast-shoulders serving as means for steadyin g and guiding the top lift as it is introduced into the holder, and by this movement of the top lift into place the arms are opened or caused to be moved from each other sufliciently to permit the top lift to pass by the shoulders and come in contact with the back pressure-plate,

and the top lift is moved sufficiently far beyond the shoulder d to permit the shoulders to close from each side of the top lift into a position to receive the breast of the top lift when it is moved backward by hand or by the forward movement of the back holding pres sure-plate. I consider this feature of very considerableimportance, especially where the top lift is fed automatically from a stackholder, as the projecting ends of the holder serve to receive and center the top lift and to hold it while it is being directed oroarried into the holder proper, and so far as this feature of the invention is concerned the same advantage would be obtained if the shoulders 01 were not used and the top lift held by the bearing of sections of the arms upon the side. I would say that Where the lift is pressedby hand in the holder with the shoulders 01 it is possible to do away or dispense with the use of.

the back pressure-plate, but as a rule it is preferable to use it.

The invention in question provides a simplicity of construction and an accuracy very desirable in this class of machines, and not only this, but considerable advantage is obtained from the fact that the various top-lift,

heel-blank, and .nail carriers which constitute the delivery mechanism are held in favorable positions for loading by the operator or by an attendant when out of operative po.- sition, and are moved from such favorable positions to their operative positions by an easy and accurate movement.

It will be understood that while I have used throughout the specification the terms nailcarriers, heel-blank carriers and holdersj and top-lift carriers and holders in referring to the various elements I have, for the purpose of condensing the statement of invention in the claims as much as possible, used the generic term carrying device or delivery mechanism to indicate anyone of these various devices. These different instrumentalities are not, however, true equivalents of one another, as each has a distinct and independentfunction in a different place and in different relations in connection with the other elements which complete the combination, the nail-carriers operating above the templet and feeding nails to the latter,

Ioo

the heel-blank carrier presenting a heel to I the under surface of the templet and holding it there during the driving of the attaching-nails through the templet into the blank, while the top-lift carrier transfers a top lift to a position under the templet and holds it there as the last and its shoe move upward and forces the heel, with its projecting nails, against the said top lift.

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