HEEL=NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 389,077, dated September 4, 1888.

Serial No. 242,006.

(No model.)

To all whom it may concern.-

Be it known that we, Hermon W. HORNE and James Hnwnnnson, of Haverhill, in the county of Essex and State of Massachusetts, haveinvented certain new and useful Improvements in Hcel-Nailing Machines, of which the following is a specification.

This invention relates to heel-nailing machines employing a nail-holding block having holes arranged to receive a gang of nails and hold them in the order in which they are placed in the heel, a gang of drivers which work loosely insaid block and force the nails from the block into the heel,and a top'lift plate or spanker which is brought into position over said block after the heel has been at tached and forces a top lift laid upon it onto the projecting ends of the nails after the same have been inserted in the heel, the drivers being made so short that the nails inserted by them are left protruding sufiiciently to enable them to hold the top lift.

The top-lift plate or spanker is pivoted to the nail-holding block, and is moved away from the top of said block during the operation of driving the nails, and is moved over the block after the nails are driven, so as to cover the nail-holding orifices in said block, and present a smooth surface while attaching the top lift.

This invention relates to mechanism for attaching heels to boots and shoes, and is an improvement upon that shown and described in United States Patent No. 166,7 65, dated August 17, 1875, it having for its object to provide the top-lift plate shown in said patcnt and used in connection with the heel support or plate with a holding device or catch, by which the top lift may be held in position upon the said top lift plate.

The holding device or catch is herein shown as a springactuated slide movable in a guide on the top-lift plate, the said slide normally pressing upon one face of the top lift to re tain it in position upon the toplift plate, and adapted to be thereafter removed from the said top lift, as will be described.

To this end ourinvention consists, in a heel nailing machine, in the combination of the nail-holding block, a horizontally-swinging 5o topdift plate, and a catch or holding device, substantially as described, on the top-lift plate adapted to overlap and engage the top lift positively, substantially as set forth.

Also, our invention further consists, in a heel-nailing machine, in the combination of the nail-holding block, a horizontally-swing ing top-lift plate, a catch or holding device, substantially as described, on the top-lift plate adapted to overlap and engage the top lift 50 positively, and automatic mechanism for releasing the top lift, substantially as described.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a top View of a nail-holding block and top-lift 6 plate, together with our improvements, the said plate being shown as turned out from its operative position. Fig. 2 represents a top View of the same, the toplift plate being in place. Fig. 3 represents a side view with the toplift plate in the position shown in Fig. 2. Fig. 4 represents a sectional view showing the top-lift holding device or catch displaced to release the top lift. Figs. 5, 6, and 7 repre sent modifications.

The same letters of reference indicate the same parts in all the figures.

In the drawings, it represents the nailholding block, having a gang of orifices arranged to hold the series of nails which attach a heel. The block is supported by a standard, 8, on a bed or plate, t, which will be raised and lowered, as usual, by mechanism provided for that purpose, the block being adapted to slide on said standard down to the bed t and to be noranally raised from said bed, as shown in Figs.

1 and 8, by a spring in the socket in which the standard slides. The drivers I) b are placed loosely in said orifices and rest at their lower ends on the bed or plate 6. go

The toplift plate 6, pivoted by a stud, f, to the block a, is surmounted in usual manner by a spring, 9, which normally acts to turn the top lift into position over the block a, as shown in Figs. 2 and 3.

In the operation of the machine the top-lift plate is moved to one side, as shown in Fig. 1, and the heel is placed on the upper surface of the block, a gang of nails having been pre: viously placed in the orifices of the latter. The shoe placed on an iron last is then moved into place over the block, and thereafter the parts are moved in usual manner to cause the drivers to force the nails outwardly from the orifices of the block into the heel. The drivers are of such length that they do not entirely insert the nails, but leave their heads projecting. The plate t is then depressed, so as to leave room between it and the block a and the heel for the insertion of the top-lift plate with the top lift thereon. The depression of the block releases the top-lift plate from the heel and enables the spring 9 to turn the said plate into position over the block a, as shown in Figs. 2 and 3.

The devices and mode of operation thus far described are not new with us.

In carrying out our invention we provide the top-lift plate with a top-lift engaging device or catch adapted to secure or confine the top lift to the said top-lift plate while the latter is out of position, as in Fig. 1, so that when the block and drivers are depressed and the'top-lift plate is acted upon by its spring 9 to turn it into position over the block ait will carry the top lift with it into position to he applied to the heel. We prefer to employ for this purpose a dog or catch, 2,which, as shown in Figs. 1 to 4:, is adapted to slide in a slot, 3, in the raised portion 1), against which the breast of the top lift bears. One end of said clamp is formed to bear upon the upper surface of a top lift, 4, while the latter is being carried to and placed in its proper position on the heel, and is pressed downwardly upon said lift by a spring, 5, with sufficient force to hold the lift and prevent it from being thrown edgewise out of place by the motion of the top-lift plate when the latter is swinging to place, and by the abrupt stoppage of the said plate by the stud w, which arrests it in its operative position.

The catch 2 is adapted to tilt or rock on a fulcrum, 6, so that its lift-holding end may be raised by the depression of its opposite end by the finger of the operator. In the catch is an orifice, 7, which, when the catch is moved forward to hold the lift 4, as shown in Figs. 1, 2, and 3, is located a little forward of and out of line with a steady-pin, 8, which is attached'to the base t, and enters a socket in the top-lift plate when the block bears on the base t, the office of said steady-pin in machines in use prior to our invention being to prevent the top-lift plate from turning on its pivot by the pressure of the heeltrimming knife against it.

We make the steady-pin slightly longer than heretofore, and round off or bevel its upper end, so that when it reaches the catch 2 its reduced extremity will first enter the orifice 7, and by pressure against one edge of lift.

said orifice will force the catch back, asshown in Fig. 4, until it is removed from the top It will be seen, therefore, that the operator places the top lift on the top-lift plate while the latter is in the position shown in Fig. 1, and engages the catch 2 with it, and

that the catch holds the top lift on the said as to enter the grain-surface of the top lift.

(See Fig. 7.) The top lift is readily forced onto the brads, and is held in place thereby with sufficient firmness to prevent the lift from being thrown edgewise out of place by the motion of the spanker and by its abrupt stoppage. The brads are located so near the breast of the heel, however, that the marks made by them are in that portion of the leather that is removed by the breasting operation, so that the heel is not defaced.

The brads may be arranged horizontally in the breast-supporting shoulder 11 of the toplift plate, as shown in Fig. 5, in which case it is preferable to pivot them to the top-lift plate, so that they can swing upwardly when the heel is being removed, and will not therefore be wrenche'd or broken by the removal of the heel. The brads when thus arranged may be held in their normal positions by springs m.

Another modification is shown in Fig. 6, in

the opposite edges of the top lift near the breast, as shown.

It will be seen that by our improvement the expense of special mechanism for supplying the top lifts is avoided. The top lifts may be engaged with the top'lift plate by the attendant who places the heel blanks in position, there being sufficient time for this operation while the nails are being driven, so that the cost of running the machine is not increased. We claim- I 1.
