COATING APPARATUS Fil ed Dec. 29. 1931 Patented July 10, 1934 UNITED STATES PATENT OFFICE COATING APPARATUS Application December 29, 1931, Serial No. 583,695

8 Claims.

invention relates to apparatus for coating such articles as parts of shoes, examples of the work which the organization is well adapted being furnished by outsoles, insoles, the edges of uppers and the bottoms of lasted uppers, which are to receive an application of cement or other coating substance :over certain areas.

The invention has as an object the provision of a conveniently arranged apparatus, which may be operated with facility, which will insure a regular flow of the coating substance to the work and which may unfailingly be kept in proper operating condition. For the attainment of this object, the apparatus illustrated as constituting one embodiment of my invention has a novel arrangement of receptacle for :a coating substance and driven means for .efiecting delivery of the coating substance therefrom and for applying said substance to the work, together with improved means for controlling the delivery of the coating substance and for guarding against clogging of the applying means and the means delivering thereto.

In the accompanying drawing,

Fig. 1 represents my improved apparatus in perspective, parts being broken away;

Fig. 2 is a side elevation of the receptacle and more closely associated elements, parts being in section; and 1 Figs. 3 and 4 show applying nozzles adapted for operation upon articles differing from those for which the nozzle of Fig. '1 is most advantageously employed.

Standing upon legs 10, and conveniently cast one piece, is a receptacle 12 divided by a vertical partition 14 into two compartments l6 and 18, these respectively furnishing containers for such substances as cement and a solvent for said cement. The compartment 18 is preferably of relatively small capacity. A cover 20 may normally close the receptacle, it .being retained in place by a spring-catch 22. Lying transversely of the bottom of the receptacle is an elongated boss 24 having extending horizontally through it a cylindrical passage 26. Into this passage 26,

an opening 28 of considerable diameter leads from the compartment 16, while a relatively contracted opening 30 connects the compartment 18 with the passage. Fitting in and extending through the passage 26 is a sleeve 32 held against 1 .50 longitudinal displacement at the inner end by a nut 34 and at the opposite end by a handle 36 fast upon it. This sleeve serves as a valve, having through it openings 38 and 40 preferably oppositely placed and arranged to be respectively 1 5 brought into registration with the

openings

28 and 30. This allows a flowinto the sleeve from either the compartment l-6 or the compartment 18. A stop-projection 42 is shown upon the handle .36, which may, by its contact with the. bot-tom of the receptacle at opposite sides of the sleeve 32, determine the registration of either sleeve-opening with the corresponding compartment-opening. The delivery-passage within the valve-sleeve is continued by a flexible tube 44 having at its opposite extremity a cement-applying device or nozzle A (Fig. 1) arranged for manipulation by the operator. To prevent .terference with the rotation of the valve-sleeve and with movement of the nozzle, connection to the tube at both ends may be through swiveljoin-ts 46. The nozzle A appears as consisting of .a tube 48, which may be surrounded by a yieldable sleeve to furnish a better hold for the operator. At the delivery-end, this tube 48 may .becurved to one side, to more conveniently direct the discharge, and is surrounded by a brush 52, by which the applied coating is distributed over the work, this work consisting, for example, of .soles, the margins of which are to be coated. Fig.

3 shows another form B of applying nozzle. Here, the discharge is directly upon the worksurface, Without spreading effect. The nozzle B is useful for the delivery of a comparatively thick coating of cement over the bottoms of lasted shoes in preparation for the attachment of the. outsoles.- A flange 54, fixed upon the tube at a chosen distance from the delivery-opening, furnishes .a gage-surface, which, by contact with the work, will locate correctly the applied band of adhesive. Another nozzle (Fig. 4) 'may have a straight tube 56 with an outlet-slot 58 in its side at or near the otherwise closed end. This serves for applying a coating between connected parts, as shoe-uppers and their linings.

Situated within the valve-sleeve 32 beneath the

openings

28 and 30, and extending therefrom through the tube 44 into the attached nozzle in proximity to the delivery-opening, is a feeding member for the cement, this member being preferablya flexible helix 60 of spring-wire having a diameter approaching that of the interior of the delivery-conduit. In the inner portion of the sleeve 32, the helix is connected to a flexible coupling member 62 secured at its opposite extremity to the shaft of an electric motor 64, the speed of rotation of which may be governed by a rheostat 66. The motor may be carried by a mounting 68 attached to the rear of the receptacle, with its shaft axially alined with the sleeve.

While, obviously, any fluid substance may be;

delivered from either portion of the receptacle 12 exclusive of the other through the valve-sleeve 32 and connected tubing, I especially contemplate employing the container 16 for holding such acement as pyroxylin, with which work is to be coated, and the container 18 for a solvent for said cement, for example acetone, the latter being utilized for cleaning the cement-delivering connections. Consequently, in using the apparatus in this manner, the valve-sleeve, during the coating operations, will be positioned as illustrated tended band over the desired area. The nozzle joined to the tube will be selected according to the operation to be performed. The amount of cement applied and the time of delivery may be determined by the rotation of the motor, the contact-brush of the rheostat conveniently being shifted by a treadle (not shown). When the use of the apparatus is to be discontinued, the handle 36 is turned to close the opening 28 from the cement-container 16 and bring the valve-opening 40 into registration with the opening 30 of the solvent-container. With the motor in operation, the solvent will be forced through the valve-sleeve, the flexible tube and the connected nozzle, clearing the cement from the interior of the entire conduit and from the helix. Consequently, while the apparatus is at rest, there will be no cement to harden and clog the delivery-connections, and operation may be resumed at once upon shifting the valve to the cement-delivering position. It will be seen that the arrangement of the motor, its connection to the helix and the location of the valve give a compact arrangement, allowing uninterrupted access to the interior of. the receptacle and providing for a'connection of the flexible delivery-tube which facilitates manipulation by the operator of the delivery-nozzle.
