HEEL-NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 500,486, dated June 2'7, 1893.

Application filed February 6, 1891. Serial No. 380,486. (No model.)

To all whom it may concern.

Be it known that I, CHARLES W. GLIDDEN, of Lynn/county of Essex, State of Massachusetts, have invented an Improvement in Heeling-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object to improve the class of heeling machines shown in United States Patents Nos. 166,795 and 374,894, to adapt them to a greater range of work.

It is a well known fact that the majority of people wear the outer side of the heel faster than the inner side, and to overcome this difficulty in a measure, I have provided the heeling machine herein to be described with means whereby the nails to be driven into the heel to attach it to the sole end of the heel may be driven into the said heel, at that edge of the tread end or lift which is to constitute the outer edge of the heel, nearer the edge of the heel than the nails which are driven into that part of the tread end or lift nearest to its inner side, such plan of driving the nails into the heel enabling a much greater part of the heel at the inner side thereof to be trimmed or cut away than at its outer side, the amount cut away depending on the degree to which it is desired to set the tread end of the heel aside upon, or with relation to, the longitudinal center of the heel of the shoe; and provision has also been made to adapt my invention to rightand left shoes. I have also provided the heel-clamp, in itself old, with means whereby it may be adjusted automatically around the heel about a point approximatelythe center of the heel to thus better adapt the clamp to heels of right and left shoes.

The prominent features of my invention will be hereinafter described and specified in the claims, at the end of the description.

Figure '1, in side elevation, represents a sufficient portion of a heeling machine with my improvements added, to enable my invention to be understood, the lever a shown in Fig. 2, being omitted; Fig. 2, an enlarged detail below the section line at Fig. 1; Fig. 3, a detail to the right of the dotted line y Fig. 1, chiefly to show the band clamp holder and its actuating devices, the band clamp being, however, omitted in Figs. 3 and 5; Fig. 4, a detail to the right of the section line, a Fig.

looking to the rightand showing the shape of the heel when nailed on the sole and b e' fore it was trimmed; Fig. 12, a like section showing the heel trimmed.

Referring to the drawings, A represents a column; A, a walking beam; A A, two members of a toggle joint, connected with a shaft A by which to actuate the walking beam.

The walking beam has at its end a rocking block or nut m which receives a screw m connected to a last slide spindle 84E.

B is a spindle in bearings B. This spindle has an enlarged head B and is adapted to be raised and lowered by a toggle composed of members D, D, the member D being pivoted 85 at D These parts are to be found in United States Patent No. 374,89et, dated December 13, 1887.

If a heel nailed on a shoe, as hereinafter provided for, is to be trimmed on the machine,

The devices carrying the 5,

The last containing the shoe rco from a nail box it. The post shown has at its upper end a flanged head which enters a dovetailed guide-way in a laterally movable carrier 848. The nail-box 7c having its supporting pin land the pattern plate L, through the hollow shank of which the said pin is extended, and the spring to support the pin land normally keep the nail-box elevated above the pattern plate on which in practice will rest the nail driver plate, are common to United States Patent No. 166,795, dated August 17, 1875. The plate 84* at the lower end of the spindle 84, and the arm p clamped upon an extension thereof, and having at its lower end a guide-block or holder 27 on which moves horizontally a cross slide 28, it containing a vertically movable slide 29, are all as in United States Patent No. 377,301.

The plate or carriage at when a heel is to be trimmed on the machine, will be provided with grooves such as represented in the plate designated by the letter as in United States Patent No. 166,795, the said grooves being also shown in Fig. 5 of United States Patent No. 374,894, dated December 13,1887, and before referred to, but in the latter patent the said plate is not lettered.

The machines described in United States Patent No. 166,795 and in No. 377,301 each contain devices by which to adjust the position of the last holding post A to provide for right and left shoes, but by the said machines the nails were, and had to be, driven into the heel at a uniform distance from the edge of the tread end or lift of the heel, both at its inner and outer edges.

In the patented machines referred to, to provide for right and left shoes, the toe of the last was adapted to be swung from side to side about a center, approximately the center of the heel to be nailed, but in this my present invention I have devised means whereby the relative position of the post A carrying the shoe, and the nail driving devices, may be changed bodily laterally, either one or the other, in order that the nails a driven into the heel to thereby attach it to the sole, may be driven into the said heel in such manner, as shown by dotted lines Fig. 11,-that the nails to appear at the outer side of the heel, or at the outer edge of the tread end, are driven into the heel nearer to its outer side than are the nails which are driven into the heel and which are to show at the inner side of the heel, a heel attached by nails so driven into it at different distances from its edge, enabling the inner side of the heel to be trimmed away very much more than its outer side to thus leave the heel set with its tread lift nearer the outer than the inner side or edge of the heel end of the sole. This adj ustment for the purpose stated may be edected by adjusting bodily laterally either the post A or the nail-box of the heel nailing device, or both, and in the embodiment of my invention herein contained I have shown both of such adjustments.

I will first describe the means shown for adjusting the post A laterally.

Referring to Fig. 1, I have marked the plate orcarriage at the lower end of the slide 84 as 84 Surrounding the slide 84 loosely below the bearing a I have placed a head a having tracks or flanges 2, 3, which are engaged by lips or projections 4, 5, suitably connected to or forming part of the plate or carriage 84*. The head a is shown as having a stud 0. upon which is mounted a lever a suitably connected by a link a, or otherwise, with the plate or carriage 84*, so that as the said lever a is turned, the plate or carriage 84* will be moved bodily laterally on or with relation to the spindle 84 as will be apparent by inspecting Fig. 2 of the drawings.

To further meet the desires of manufacturers as to the exact position of the median line of the tread end or lift of the heel with relation to the median line of the sole, means have been provided for controlling the direction of the lateral motion of the plate or carriage 84* on the head a, the means shown consisting of slotted disks 6 formed orset into the head a and held in adjusted position by set screws 7, the said slots receiving rolleror other studs 8 extended upwardly from the plate or carriage 84". By rotating these disks more or less in opposite directions, the slots therein may be so placed that the plate or carriage 848 when moved laterally, will travel in acurved path rather-than in a direct orstraight line. Limiting screws or stops 9 are employed to determine the extent of the bodily lateral movement of the plate or carriage 84*, there being two such stops, for it will be understood that the plate or carriage will be, and is, so supported that it may be moved first bodily laterally in one, and then bodily laterally in an opposite direction, according as right and left foot heels are being nailed, it being common to heel a right and then a left, or two or more rights or two or more lefts, in succession.

From the foregoing description, it will be understood thatshould the screws 9 be screwed in so as to contact with the edges of the plate or carriages 84*, the movement of the lever a would simply cause the said plate or carriage 84 to turn about the rounded part-,- see dotted lines Fig. 2,- of the spindle 84, thus swinging the toe of the last more or less in one or the other direction, but by putting the said screws in the position Fig. 2, then the movement of the said lever will cause the part of the plate or carriage 84* at the spindle 84 to be moved bodily laterally in addition to having its outer end oscillated It will be noticed therefore that the screws or stops 9 define within established limits,which may be varied more or less according to the requirements of the work being done,the extent of the bodily lateral movement to first one and then to the other side of alinedrawn longitudinally through the last.

Referring now to the nail-box, it will be seen in Figs. 1 and 6, that the head B of the spindle is provided with slotted disks 6 like the disks 6 in Fig. 2, the slots t of the disks 6 receiving roller or other studs 8 depending from the under side of the plate or carriage as, as I shall in this instance of my invention herein designate the said device, upon whichis secured the shank of the pattern plate L. This head B at its center, is provided with a hole larger than the hollow shank of the plate L described, so that the plate or carriage 00' may be moved laterally on the spindle head B as provided for, of the plate or carriage 84 on the head a, the ends of the slots 25 in the plates 6 serving as limiting stops for the nail box in each of its two directions of movement, to place the center of the nail box to one or the other side of aline drawn longitudinally through the last. The plate or carriage 0c is kept down on the head B by suitable stud screws 12, one of which is shown in Fig. 6, as tapped into holes 13 of the said head, the heads of the said screws resting on shoulders on countersunk holes 14, the holes being enough larger in area than the screws to enable the plate or carriage ac to be moved on the said screws. The plate or carriage as has depending pins 16 which are adapted to be engaged by plate or carriage actuating devices 17, herein shown as levers pivoted on the head B at 18, movement of the said levers about their fulcra moving the plate or carriage 00' laterally and in a straight or curved path according to the particular direction orinclination of the slot in the said disks 6 By moving one or the other of the plates or carriages 84 or a," bodily laterally as described, or both of them bodily laterally, the stud Z and the pins 19 of the post A may be put more or less out of vertical linelaterally, which enables the nails n to be driven into the heel while the latter is held pressed in usual manner between the nail-box-k and the sole of the shoe, and the U-shaped line of nails, see Fig. 10, are driven into the heel, see Fig. 11, at one side of the center thereof or at one side of amedian line drawn through the sole longitudinally from end to end, thus enabling the inner side of the heel to be subsequently cut away much more than the outer side, the trimmed heel showing the nails however substantially equi-distant from the edges of its tread end or lift, as in Fig. 10 which shows the heel Fig. '11 trimmed after it has been nailed upon the sole of the shoe.

It is not intended to limit this invention to the exact devices shown for accomplishing the bodily lateral movement of either the post A or of the nail-box 7c.

The vertical slide 29 referred to, is provided at or near its lower end at its front side with a dove-tailed groove or way shown best in Fig. 1, shaped to receive a segmental shaped band-clamp holder 40, which receives between its ends suitable pivots 41 of a V-shaped frame 42, which supports the band clamp 55, the said devices being essentially as in United States Patent No. 217,867. The segmental shaped holder 40 has at its upper end aseries of teeth adapted to be engaged by an adjusting device shown as

arms

44, 44 on a rod 45 7c extended through a sleeve 47 projected backward-1y from the vertical slide 29, the upper end of the arm 44 having a pin or projection 46 which normally stands between two like fingers or band clamp limiting stops 48,

48, pivoted at 49 on the frame A, the said fingers or stops being adjustable as to their position by suitable screws 50. When the plate 84 is adjusted or turned on or with relation to the spindle 84 as described, the pin 46 strikes against one or the other of these fingers stops and slides the holder 40 in the segmental guide referred to, thus enabling the clamp 55, which embraces the counter of the shoe to adapt itself to the requirements 85 of a right or left shoe.

Prior to my invention,I am not aware that a clamp for the counter of a shoe to be heeled or trimmed has ever been made adjustable around the post A holding the last, and has had its movement regulated or determined by or through limiting stops, so that this invention is not limited to the exact form of device represented for this purpose, as it is obvious that other equivalent forms of device 5 might be employed without departing from my invention.

The lever A mounted upon the head and operatively connected with a part of the plate or carriage 84 and the lever 17 mounted I00 upon the head B and operatively connected with the plate or carriage 00, each constitute what I shall denominate in the claims as plate or carriage actuatingidevices, I meaning thereby, devices through or by which bodily lateral movement may be imparted to the post A in one instance, and the nail-box 7c in the other instance, and I desire it to be understood that the said plate or carriage actuating devices may be constructed differently [10 from what is shown in the accompanying drawings, and yet not depart from my invention, as I am not aware that such movement has ever been imparted to either the post or the nail-box within limits in each of two dir15 rections laterally to a line drawn longitudinally through the center of the last to accomplish the result aimed to be accomplished in this present invention.

The shoe-holder 56, serving to hold the shoe, 1 20 to efiect the movement bodily laterally of the said carriage between the said stops thereby enabling nails to be driven into the heels of right and left shoes differently, as described, and leave the nailed heels in condition to be trimmed away more at their inner than at their outer side edges to thus ofiset the tread of the heels, as set forth.
