4 Claims. (01. 12-80) This invention relates to improvements in coating apparatus and is herein illustrated as embodied in a cementing machine for shoe parts.
Machines of the impression type in which an applying pad is movable from a position where it picks up a supply of coating material to a position where it applies the coating material to the work in the fashion of a rubber stamp are extensively employed for marking various shoe parts. They have to a limited extent been utilized for applying cement. When used for marking, an ordinary absorbent pad is satisfactory for delivering a supply of ink to the applying member. This, however, is not satisfactory for cement since the pad would so rapidly become gummed up.
In view of this, an object of the invention is to provide in a machine of this type an improved cement-supplying arrangement whereby just the desired quantity may be delivered to the applying pad as the latter is swung to its pick-up position.
In the illustrated embodiment and in accord ance with a feature of the invention, a shallow cement-supply receptacle has associated with it a supplying member movable from. a position where it is submerged beneath the level of the cement to an upper position where it contacts with the face of the applying pad as the latter is swung to its rear or pick-up position. As illustrated also, this supplying member, in the form of a pick-up grid, is mounted on parallel links and the applying member or pad, also mounted on parallel links, is interconnected with the pick-up grid as by means of a cam on one of the links of the applying pad designed to cooperate directly with one of the links of the pick-up grid to raise the latter.
These and other features of the invention will be best understood from a consideration of the following description taken in connection with the accompanying drawings, in which Fig. 1 is a side elevation of the machine;
Fig. 2 is a plan view thereof;
Fig. 3 is a fragmentary side elevation showing the applying pad in contact with the pick-up grid, and
Fig. 4 is a vertical section on the line IV--IV of Fig. 1 through the applying pad and a piece of work.
The machine is illustrated as utilized for the application of a band of cement to the beveled annular opening H1 in the forepart of an insole 12 but it will be understood that the machine is adapted for use for various sorts of work merely by changing the shape of the applying die or pad M. This pad may be made of any suitable material but is here shown as comprising an annular member of sponge rubber, shaped like the opening in the insole and beveled on its under face. This pad is cemented to the under face of a plate l6 having a transverse groove IS with overhanging edges so that it may be slid over the heads of screws 20 depending from a carrier frame 22. In this carrier frame is a springpressed plunger 24 for holding the-plate iii of the pad in centered position on the carrier 22. This plunger may be lifted by means of a thumb piece 26 when it is desired to change applying pads.
The machine frame 30 comprises a base plate on which is supported a work table 32, this table and the base plate of the machine being provided with an opening 34 corresponding to the opening in the insole l2 so that any cement inadvertently squeezed out or spattered from the pad will fall through the opening without smearing the work table. The carrier 22 comprises a rectangular bottomv piece, in which is mounted the plunger 24, and superposed on which are side members 36, 38 connected by a crossbar 40 provided at the top with an operating handle 42. The impact as the applying pad l4 contacts with the work is lessened by means of a spring 44 mounted on the base plate of the frame and engaged by a lip 46 on the carrier 22.
In order that the applying pad may be swung from its operative or applying position at the 30 front of the machine to an inoperative or pick-up position at the rear of the machine, the frame of the machine is provided with spaced uprights 50 and 52, bolted to flanges 5| integral with the base, and on which the carrier 22 is swingably mounted by means of parallel links. One set of these, attached at one end to the uprights and at the other end near the bottom of the side pieces of the carrier, comprises links 54 and 56 which are of the same length but are staggered so that the link 54 is secured to a projection 58 (Figs. 1 and 3) on the side bar 38 while the link 56 is attached directly to the side bar 36. In addition, similar links 60 of another set have at their front ends inward projections 62 whereby they are pivotally attached to the side frames 36 and 38 of the carrier and at their rear ends are provided with cams 64 through which pass pivot screws 66 to pivotally support them on the outer sides of the uprights 50 and 52.
The machine is also provided with cementsupplying apparatus which is mounted near the rear of the base of the frame 30, considered as viewed by an operator facing the right end of the machine, as shown in Fig. 1, and this apparatus comprises a removably mounted receptacle 10 attached to the base of the frame by thumb screws 12. In this receptacle is a perforated grid plate 74, the form of which may be varied in accordance with the shape of the applying pad 14 and which is adapted to be immersed in the cement in the receptacle, as shown in Fig. 1, or to be lifted above the level of the cement, as shown in Fig. 3. To this end, the grid has vertical hangers I6 enabling the grid to be secured to parallel links 18 and 8 arranged in pairs and pivotally secured to the uprights 50 and 52. The lower links 18 are extended at 82 forwardly of their pivot points and provided with rollers 84 engaged by the cams 64 on the links 60 of the pad carrier whereby the grid may be raised from the receptacle. It will be noted that the grid is detachably secured to these links 18 and 83 so that it may be removed for cleaning or for substitution of a grid of different shape, and to this end the hangers 16 have angled slots 86 for the reception of pins 88.at the ends of the links 78 and also a have vertical slots 99 open at their upper ends for the reception of pins 92 at the ends of the links 80, these pins 92 being held in engagement with the hangers 16 by coiled springs 94.
In the use of the machine, pieces of work I? are placed on the work table 32'and the operator, grasping the handle 42, oscillates the applying pad I4 from its cement-receiving position, as shown in Fig. 3, to its applying position, as shown in Fig. 1. The arrangement of the carrier links for the applying member and for the supplying member and of the cams 64 enables the grid 74 to be withdrawn from the receptacle and re- 7 turned thereto with a minimum of disturbance of the cement in the receptacle.
Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
1. In a coating apparatus, an applying member mounted for movement from an applying position to a coating-pick-up position, a movably supported coating-supplying member, and cam means associated with said applying member for lifting said supplying member into contact with the applying member as the latter is moved to its pick-up position.
2. In a coating apparatus, a coating-applying member, parallel links supporting said member for swinging movement from a coating-receiving position to an applying position, a receptacle, a coating-supplying member dipping in the material in said receptacle, means for supporting said supplying member for movement into and out of the material in the receptacle, and a cam on one of the links cooperating directly with said latter supporting means to raise the supplying member out of the receptacle as the applying member is swung to pick-up position.
3. In a cementingrmachine, a frame, awork support thereon, a cement-applying member supported on parallel links pivoted to said frame, a cement receptacle on the frame, a grid in said receptacle, parallel links supporting said grid, and a direct connection between the two sets of links whereby the swinging of the applying member away from the work lifts the grid to contact with the applying member and supply cement thereto.
4. In a cementing machine, a frame, a work support on said frame, a cement-applying pad, parallel links swingably supporting said pad, a cement receptacle on the frame, a grid movable in said receptacle, parallel links supporting said grid for movement into and out of the receptacle, a roll on one of said grid-supporting links, and a cam on one of the links supporting the applying member positioned to cooperate with said roll to lift the grid from the'receptacle into contact with the applying member as the latter is swung to inoperative or pick-up position.
