CEMENT-APPLYING MECHANISM.

Specification of Letters Patent.

Application filed February 8, 1907.

Patented July 4, 1911.

Serial No. 356,308.

To all whom it may concern:

Be it known that I, EZRA E. C. PACKARD, a citizen of the United States, residing in Lynn, county of Essex, and State of Massachusetts, have invented an Improvement in Cement-Applying Mechanism, of which the following description, in connection with the accompanying drawing, is a specification, like letters on the drawing representing like parts.

This invention has for its object to provide a novel cement applying machine for delivering cement on the surface of stock on a stock support, or being fed through the machine.

In accordance with my invention, I have combined with suitable mechanism herein shown as of the class employed in ordinary skiving machines, a receptacle to receive cement, and a cement delivery nozzle provided with a valve that is moved within the nozzle by contact of the exposed end of thevalve with the stock sustained by any usual stock feeding wheel or support, said valve having a connected spring that acts when the stock is absent from the feeding wheel to maintain the valve closed.

Figure 1 in front elevation shows part of a machine with which I have embodied my invention in one of the best forms now known to me; Fig. 2 is an enlarged sectional detail of the nozzle and its valve closed; and Fig. 3 a detail showing the upper end of the receptacle.

The framework A, the shaft A on which is mounted the stock-feeding wheel B, the disk presser B for acting on the upper side of the stock sustained on the feeding wheel, its carrying shaft 13 and wheel B driven by belt D driven from any usual pulley at the opposite end of shaft A, are and may be all as usual.

I have mounted on the end of the overhanging arm A" of the framework, a receptacle G for cement or other liquid adhesive, said receptacle having at its lower end a foot C having a hollow shank extended through said arm, said foot being provided with a passage for the reception of a cock C having ahandle C and a transverse opening, a port a leading from said receptacle to said opening, a second port a leading through said shank into a suitable flexible tube a cement passing from said receptacle through said cock when opened into a nozzle D secured to a depending portion A of the framework in suitable mannor as by screws D. The nozzle D is rigidly secured in place and its end therefore occupies a fixed distance from the feeding wheel or stock-support.

The upper end of the receptacle C has fitted closely therein a hollow plunger 1) that rests on the top of the cement in said receptacle, the plunger having an inturned hub 6*, see Fig. 8, on which acts the lower end of a screw 6 having a handle 11 by which the screw may be turned to force the plunger into the receptacle to force the cement therefrom through the open cock G into the nozzle. The receptacle has two rods 6 that serve as guides for the cross head at that sustains the screw Z). The cross head has at its ends screw rods cl made adjustable vertically by thumb nuts 0Z said rods having connected to their lower ends the upper ends of springs 0Z attached at their lower ends to studs d The valve D has a stud 2 that is extended outwardly, see Fig. 2, through a slot 3 in the nozzle where said stud has connected with it a spring 6 attached at its opposite end to a stud e fixed to part of the nozzle, said spring acting normally to move said valve in the direction of the arrow thereon, Fig. 2, so that its inclined face 4 is held firmly on the inclined seat 5, the lower end or toe 6 of the valve extending beyond the lower end of the nozzle, the extremity of said toe when the valve is closed being arrested a short distance from the upper side of the feeding wheel.

When stock to be cemented is laid on the feeding wheel the upper side of the stock by contact with the toe 6 of said valve D raises the same slightly in the nozzle against the stress of the spring 6, thus forming a space between the face 4|: and seat 5 through which cement may issue onto the stock.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is In a machine of the character described the combination of stock supporting and feeding means, a receptacle for cement, a nozzle connected to said receptacle and having its mouth at a fixed distance from and close to said stock-supporting means and provided with an inclined valve seat at its mouth, a valve for said nozzle having an inventing the escape of any cement when no stock is beneath the nozzle month.

In testimony whereof, I have signed my name to th1s speclficatlon, 1n the presence of two subscrlblng witnesses.

EZRA E. G. PACKARD.
