CEMENTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 614,857, dated November 29, 1898. Application filed November 11, 1897. Serial No. 658,186. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM GORDON and PETER A. COUPAL, citizens of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Cementing Apparatus; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to cementing apparatus for boot and shoe Work, and more particularly to a cementing apparatus for applying a coating of cement to the lipped surface of a lipped insole.

It is now usual in the art to form an insole of a layer of leather or other suitable material and a layer of thinner material which is cemented to the lipped surface of the main layer, indented over the lip, and cemented to the feather outside of such lip.

The present invention relates to a cementing apparatus which will apply a coat of cement over the lipped surface of the insole, so arranged that the cement will be applied to both surfaces of the lip and insure that the angles between the lip and the surface of the insole will be properly supplied with cement to properly secure the reinforcing material thereto.

To the above end the present invention consists of the devices and combination of devices which will be hereinafter described and claimed.

The present invention is disclosed in the accompanying drawings, in which- Figure 1 shows aside elevation of a cementing apparatus involving the same. Fig. 2 shows a sectional view through the brush, showing the cement-tubes in elevation. Fig. 3 is a fragmentary view of the brush, such as shown in Fig. 2, the lower ends of the tubes being shown in section. Fig. 4 shows a modification of the invention when used as a lipcementer.

Similar letters of reference designate corresponding parts throughout the several views.

In the form of the present invention, illustrated in Figs. 1, 2, and 3, A represents the cement tank or reservoir, which may be of any suitable or convenient construction and arrangement, and B represents the brush or cement applying device.

The brush B is held within a thimble Z ,which is secured by means of a tubular nut b to a cock b the cock 6 being in turn secured to a pipe 6 which leads from the cement-resen voir A and through which cement is conducted from the tank A to the brush B.

Located within the brush B is a cementtube 19 which is designed to supply cement to the brush B, said tube 11 being preferably located in the center of the bristles forming ,the brush and the lower end thereof being located some distance above the lower ends and 3.

as it is passed beneath the brush B and also to insure the proper application of cement to sole, the brush B is provided with two lipcementing tubes 12 and b, the upper ends of which are securely fastened within the sleeve 1) and the lower ends of which are bent toward each other, as clearly shown in Figs. 2 and 3, the space between the lower ends being sufficient to receive the projecting lip of the insoles. The tube b is preferably arranged with its lower end just within the bristles of the brush and the tube 12 is bent outwardly from the bristles and then toward the tube 12 the lower end thereof being outside of the bristles of the brush, as clearly shown'in the drawings. Thetubesb and b conductcement from the tank A to their lower ends, which are arranged to engage the opposite sides of the lip of the insole, and thus the surfaces and angles of the lip will be properly coated with cement. The lower ends of the tubes 5 and b engage the lip of the insole upon opposite sides, and thus guide and control the relative movements of the insole and brush during the application of cement to the lipped surface of the insole. The lower end of the brush B is preferably tapered or beveled off or formed wedge shape, as common in brushes of this type, and when the insole is pressed up firmly against the same the bristles will along with the lip between the lower ends of of the bristles, as clearly shown in Figs. 2

In order to properly guide the lipped insole the surfaces of the projecting lip of the in- I spread out and bend as the soles are moved the tubes b and b and will evenly spread the cement along the surface of the sole, and the lip and feather insuring that the angles between the lip and face of the sole will be properly supplied with cement. The Valve of the cock b may be of any ordinary construction and is preferably connected with a lever b which at the end is connected to a spring 11 whereby said lever b is raised to close the valve, and said lever is connected with a treadle (not shown) by a rod 1), whereby the lever may be depressed to open the valve to permit cement to flow to the cementtubes 1)", b and b.

In the operation of the device as above described a lipped insole is presented to the brush B in such position that said brush will engage the surface of said sole within the lip, the lip being inserted between the tubes b and U. The lever 11 is then depressed to open the valve in the cock b to permit cement to flow into the cement-tubes b b and I). The sole is then moved around beneath the brush guided by the tubes b and b, which embrace the lip on the insole. When the surface has been properly coated with cement, the treadle is released and the spring'b raises lever b closing the valve in the cock b thus stopping the flow of cement.

The apparatus may be provided with any suitable pump C, whereby pressure may be exerted upon the cement in the tank A to cause it to flow freely.

In the modification of the invention shown in Fig. 4 the brush B and the cement-supplying tube 1)" are omitted, and the sleeve 1) is provided with a closed end 19 into which the tubes 19 and b are secured in any suitable manner, or instead of securing said tubes to a sleeve said tubes may be otherwise suitably supported and connected with the supply-reservoir A to receive cement therefrom. In this construction the lower ends of the tubes 6 and I) are arranged in substantially the same positions as shown in the first form of the invention and are adapted to receive the lip or other projecting portion of the insole between their lower ends and supply cement to the opposite faces of the lip, after which the remaining portions of the lipped surface of the insole maybe coated by abrush in the usual manner.

Having fully described our invention and its mode of operation, we claim as new and desire to protect by Letters Patent of the United States- 1. A cement-applying apparatus, comprising a supply-reservoir and cement-applying tubes connected therewith, said tubes having their lower open ends disposed adjacent to and turned toward each other in position to supply cement to the opposite faces of the lip of an insole or other object passed between said tubes, substantially as described.

2. A cement-applying apparatus comprising a supply-reservoir and a brush connected therewith, said brush being provided with cement-tubes, the lower ends of which are adjacent to each other and arranged to supply cement to both sides of an article passed between them, substantially as described.

3. A cement-applying apparatus for lipped insoles comprising a supply-reservoir and a brush connected therewith, said brush being provided with cement-tubes arranged to engage the opposite sides of the lip, and to supply cement thereto and to guide the relative movements of the sole and brush, substantially as described.

4. A cement-applying apparatus comprising a supply-reservoir and a brush connected therewith, means to supply cement to the brush and a combined cement-applying and sole guiding device, substantially as described.

5. A cement-applying apparatus comprising a supply-reservoir a brush connected therewith, a cement-tube within the brush to supply cement to said brush, and a pair of cement-tubes having their lower ends bent toward each other, one of said tubes being projected outside of the brush, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
