IRA J. WEBSTER, OF HAVERHILL, MASSACHUSETTS.

HEEL-ASSEMBLING MACHINE.

To all whom it may concern:

Be it known that I, IRA J. \Vuesrnn, of Haverhill, county of Essex, State of Massachusetts, have invented an Improvement in Heel-Assembling Machines, of which the following is a specification.

This invention relates to certain improvements in the heel building machine disclosed in my pending application Serial No. 477,064, filed February 10, 1909.

The objects of the present invention are to provide a simple and etlicient means for applying an ample quantity of cement to each lift previous to the assembling operation, so that the lifts will be thoroughly cemented together when the heel is assem bled, and to improve said prior device in other particulars, as will hereafter more fully appear. I accomplish these objects by the means shown in the accompanying drawing, in which,

Figure 1 is a side elevation, partly in section, of a device made according to my invention. Fig. 2 is a longitudinal section on the line 22, of Fig. 5. Fig. 3 is a cross section on line 3-3 of Fig. 2. Fig. 4 is an enlarged detail View of the heel form portion of the machine. Fig. 5 is a cross section on line 5-5 of Fig. 1. Figs. 6 and 7 are a detail sectional and end views of one of the nozzles.

As shown in the drawing, I provide a casing a having a series of chambers therein adapted to receive heel lifts of different sizes, the lower ends of said chambers being open and heel supports Z) being provided at each side of each chamber to engage the edge portions of a lift and support a stack of lifts therein. I further provide a pair of lift-supporting guideways 0 which extend downwardly directly beneath the supports Z2 from one end of the casing to the other. A carrier 03 is mounted to slide on and between horizontal guideways e supported directly below the lift supporting way 0, said carrier having a lift-engaging device cl mounted thereon, said device being adapted to extend between said ways .0 and supports 5 and to remove the bottom lifts successively from the stacks contained in'said chambers. A supporting plate is connected to said carrier in front of said engaging device, said plate being supported in said guideways e and being adapted to Specification of Letters Patent.

fit into the bottom of the heel form 9 when said carrier is moved into its extreme left hand or advanced position.

The apparatus thus far described operates in substantially the same manner as the apparatus described in said prior application. The bottom lifts of the stacks are successively removed and superimposed on the ways 0 by the carrier (Z, and, when the lift of the last stack has been removed, the assembled heel slid from the ways 0 onto the plate f and pressed into the form g. A nailing device is mounted over the form and comprises a throat 0 having a driver j therein, which is adapted to force a nail through the middle portion of the heel and to bear against the heel after the nail is driven, so that, when the carrier is moved rearwardly, it will hold the heel in the form, thereby enabling plate f to be withdrawn from beneath the heel, to permit the latter to fall through the open bottom of the holder, into the chute is, as shown in Fig. t.

The cement applying means which I preferably employ comprises a horizontal pipe m having a series of uprightitubes a leading vertically from the upper side thereof, one of said tubes being disposed directly beneath each chamber of the casing a,except the first, and each being arranged to direct a jet of liquid directly against the under side of the lift which is supported directly thereabove. The outlet of each branch pipe is preferably provided with a spraying device or nozzle 0 which tends to break up the liquid as it is forced therethrough, and each pipe n is also preferably provided with a valve h for closing the same, or varying the passageway therethrough. The pipe m leads horizontally into a tank (1 and is connected thereto by an opening m, in its side, and a piston or plunger 1- is mounted in theend portion of said pipe, the stem of said plunger being connected to the lower end of a lever s, by a pin and slot connection, said lever being pivoted at s to swing in a vertical plane midway between the guideways a, and in position to be engaged by the carrier (Z. A spring t is mounted on the stem of said plunger 1* in engagement with a perforated cap a on the end of the tube m and a collar 1' on the plunger stem, and acts normally to hold the plunger in the Withdrawn position of Fig. 1, in which position the front end of the plunger is withdrawn to one side of the opening m in the pipe m, through which the cement in the tank may flow into the pipe and fill the same.

With the above described device when the carrier is moved, back after performing the operation already described, and when it has nearly reached the end of its backward movement, it engages the upper end of the lever s, swinging the same so as to cause a quick impulse of the plunger 7, forcing the latter forwardly beyond the opening in and causing a series of jets of cement to be forced through the nozzles 0 against the bottom lifts of the stacks, thus causing the under sides of said lifts to be covered with an ample quantity of cement, as shown in Fig. 1. Any surplus of cement will be received by an inclined drip trough 2) arranged below the pipe m, said trough being adapted to conduct the cement into a receptacle w at its lower end.

To prevent spattering at the sides of the casing, when the cement strikes the lifts, I provide a pair of plates 00, which are connected to the casing at each side, and de pend from the under side thereof for a short distance below the lift supports b.

As soon as the carrier is advanced to remove the cemented lifts, as before described, and moves out of engagement with the lever s, the spring I? will force back the plunger to the initial position of Fig. 2, and during the time in which the carrier is moving to the opposite end of the casing, and returning, the cement will flow into and fill the tube on through the aperture m, so that the operation may be repeated on the return of the carrier.

With the above described construction, if all the branch pipes were of the same size the jets delivered from the nozzles nearest the plunger would be of greater volume than those at a greater distance therefrom. This difficulty may be avoided by gradually increasing the area of the passage-ways through said branch pipes, from the tank end of the pipe to the opposite end thereof. This may be conveniently accomplished by adjusting the valves with which said pipes are provided. In case one or more of the lift-receiving chambers should not be used it is merely necessary to close the valve in the corresponding branch pipe.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a heel-assembling machine, the combination of a series of lift-holders, and means for ejecting liquid cement simultaneously against corresponding sides of'the lifts held by said holders, substantially as described.

2. In a heel-assembling machine, the combination of a series of lift holders, a corresponding series of nozzles, and means for ejecting liquid cement from said nozzles against corresponding sides of the lifts held by said holders, substantially as described.
