APPARATUS FOR USE IN THE MANUFACTURE OF BOOTS AND SHOES.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed February 24, 1913. Serial No. 750,308.

.To all whom it may concern:

Be it known that I, FREDERICK M. FURBER, a citizen of the United States, residing at Revere, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Apparatus for Use in the Manufacture of Boots and Shoes, of which the following description, in connection with the accompanying drawings, is a specifica- 0 tion, like reference characters on the drawings indicating like parts in the several fig- UI'GS.

This invention relates to mechanisms and devices for use in the manufacture of boots .5 and shoes for applying liquids to ortions of the work; and it will be herein isclosed as embodied in an apparatus designed particularly for handling tip repairing enamel.

A considerable percentage of the shoes manufactured from patent or enameled leathers require treatment before they are packed to efface cracks that appear around the toe portion of the upper after the lasting operation has been performed. The

usual method of repairing shoes that are defective from this cause consists in bufiing off the coating of enamel in the region of the cracks and then applying to the bufl'ed spot several coats of a liquid compound usually 50 termed tip repairing enamel which is made especially for this purpose. This enamel may be applied and worked into the leather by hand or with the aid of a machine of the character disclosed in my prior Patent No. 1,096,423, granted May 12, 1914, which patent is assigned to the assignee of the present invention.

This invention provides an apparatus which, while capable of other uses, is designed especially for use in the tip repairing operation to hold the repairing enamel and to apply it to the shoe. In its preferred form the apparatus comprises a novel form of container and a dispensing valve of novel construction and having particular utility for the purposes above mentioned.

The invention will be readily understood from the following description when read in connection with the accompanying drawings,

in which Figure 1 is a view in side elevation of an apparatus embodying the invention in its preferred form; Fig. 2 is a sectional view of the valve with which the apparatus is equipped; Fig. 3 is a front view of the valve; and Fig. 4 is a view similar to Fig. 2 showing the valve open.

The apparatus shown in the drawings comprises a hollow container 2 having internal shelves or projections 4 adapted to sup port in inverted position a bottle 6 of enamel or other liquid so that its contents can drain into the container. by a removable cover 8 that normally shuts over its open end and rests upon a circumferential rim or flange 10 formed on the container, in which position it is clamped by means of a thumbscrew 12 threaded through the wall of the cover and entering a narrow vertical slot or saw cut 14 formed in the container above the flange 10. Below' the shelves 4 is a chamber preferably of suiiicient volume to hold the entire contents of the bottle 6; and this portion. of the container is provided with a stirrer consisting of a paddle 16 mounted rigidly on a small spindle 18 that extends loosely through the walls of the container and is bent outside the container to form a handle 20.

A dispensing valve is provided at the lower end of the container and comprises a body 22 having a tapered shank fitting tightly into a correspondingly tapered hole formed in the bottom of the container. This body is bored vertically and is provided at its lower end with an inclined delivery nozzle 24 drilled to communicate with the bore of the body. The flow of liquid through the valve is controlled by a gate 26 having a portion constructed to bear against and close the open end of the nozzle and having a bifurcated shank 1portion straddling the body 22 but'pivota ly connected thereto by the stud 28. The lower end 30 of the gate is turned backwardly in a direction substan tially parallel with the nozzle to form a rounded portion adapted to be engaged by the shoe to operate the valve and this curved end is slotted as best indicated at 31 in Fig. 3. It should be noted that the pivotal support for the. gate is located at one side of a line erected at the center of and perpendicular to the plane of the end of the nozzle 24. Consequently, as the gate is moved upwardly about its pivot to permit the flow of liquid through the nozzle it will swing across and outwardly away from the end of the nozzle and it will, of course, have an opposite move- The container is closed.

ment in closing. This arrangement enables the gate always to find a firm seat on the end of the nozzle irrespective of wear; and the scraping or sliding motion across the end of the nozzle removes any dried enamel that otherwise would accumulate at the end of the nozzle. he gate is normally held in its closed position by means of a plunger 32 that is located in a socket formed in a boss 34 extending from one side of the body 22 and is pressed downwardly by a spring 36 which is confined in said bore by a screw 38.

In using the apparatus a bottle of the enamel or other liquid to be used is placed in the container 2 in the position indicated in Fig. 1 where its contents can drain thoroughly even thoughthe liquid be more or less viscous as in the case of most tip repairing enamels. The cover 8 is secured on the container closing it tightly to prevent evaporation of the liquid. When it is desired to apply enamel to the shoe it is merely necessary to press the shoe upwardly against the curved end 30 of the gate 26 in the manner indicated in Fig. 4. This operation swings the gate into its open position'and allows the enamel to flow freely through the nozzle 24 and through the relatively wide slot 31 on to the work, the slot being at this time substantially in alinement with the delivery opening of the nozzle. By moving the shoe under the valve while holding the gate raised, a streak of enamel is applied to the shoe. As soon as the gate is released by the work the spring pressed plunger 32 immediately closes it stopping any further flow of liquid.

The form of valve shown is of advantage in the application of tip repairing enamel to the toes of shoes since the enamel flows on to the shoe through the slot 31 and the portions of the gate at each side of the slot serve as guides or guards when the enamel is being applied close to the welt to prevent smearing enamelupon the welt, as will be evident from an inspection of Fig. 3. Tip repairing enamel, in common with many. other liquids used in the manufacture of shoes, usually contains a considerable percentage of driers or volatile liquids; and the apparatus of this invention has particular advantages in handling materials of this character since it prevents the evaporation of these volatile substances and it enables the workman to apply the enamel or other liquid to the shoes at any desired intervals without exposing any substantial'amount of unused material to the atmosphere.

Having described the invention, what I claim as new and desire to secure by Letters Patent of the United States is 1. In an apparatus of the class described, a body provided with a nozzle having a discharge passage formed therethrough and a gate arranged to bear against the end of said nozzle to close said discharge passage, said gate being so mounted that its move- I ment in a fixed path across, and simultane- 2. In an apparatus of the class described,

a body having an open ended delivery nozzle, a gate pivoted to said body and having a part arranged to bear against the end of said nozzle and prevent the flow of liquid therethrough, said gate being mounted to swing in a fixed path across and simultaneously away from the end of the nozzle in opening and to have an opposite closing movement, andmeans for normally holding said gate against the end of the nozzle.

3. In an apparatus of the class described, a body having an open ended delivery nozzle extending therefrom, a gate having a shank portion pivoted on said body and having a part. arranged to bear against the end of said nozzle to stop the flow of liquid therethrough, said gate being pivoted at a point so located with reference to said delivery opening that the part of the valve in contact with said opening has an opening movement across and outwardly away from the end of the nozzle, and means for yieldingly holding the gate in its closed position, said gate having an extension projecting below the nozzle shaped for engagement with the work and extending substantially parallel to the nozzle, said extension having a relatively wide slot formed therethrough between its edges arranged to move into substantial alinement with the delivery opening of the nozzle when the gate is opened.

4. In an apparatus of the class described, the combination of a container constructed to support a bottle therein in inverted position and having a chamber into which the contents of said bottle can drain, a stirrer mounted in said chamber, a cover for said container and a dispensing device communicating with said chamber below the stirrer and constructed to control the delivery of liquid from the chamber.

5. In an apparatus of the character described, the combination of a container having internal projections arranged to support a bottle therein in inverted position and having a chamber below said projections into which the contents of said bottle can drain, a stirrer mounted in said chamber, a cover arranged to close said container with the bottle therein, and a dispensing device communicating with said chamber below the stirrer and constructed to control the delivery of liquid fromsaid chamber.

6. In an apparatus of the class described, a nozzle provided with a discharge passage, a gate formed to cover the end of the nozzle to close said passage, said gate being pivsides of the nozzle and having extensions constructed and arranged to be engaged by the work for opening the gate and also to prevent the fluid from spreading laterally upon portions of the work at the sides of the nozzle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
