Patented May 6, 1930 UNITED STATES PATENT OFFICE' EDWARD ERICKSON, DECEASED, LATE 0F BEVERLY, MASSACHUSETTS, BY MARY E. ERICKSON, EXECUTRIX, 0F BEVERLY, MASSACHUSETTS, ASSIGNOR T0 UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY FLUID-APPLYING MACHINE Application led February 26, 1927. Serial No. 171,317.

This invention relates to fluid-applying .machines for use in the manufacture of boots and shoes and is illustrated as embodied in a machine arranged to apply cement to economy insoles.

Vhen machines used for applying uid to various boot and shoe parts are used in connection with soles and insoles, the diiiiculty of handling the. work without interference between the soles and parts of the machine becomes somewhat acute, especially when following around the deeply indented shank portion of some such insoles. Machines have been shown in my prior application, Serial No. 57 9,443, filed August 3, 1922, upon which Letters Patent of the United States No. 1,669,508 were granted May 15, 1928, and in application Serial No. 122,150, filed July 13, 1926, in which a frusto-conical applying roll is mounted upon an axis at the frontof the machine inclined ydownwardly-toward the rear, and in which fluid is supplied to this roll from a receptacle disposed to the rear thereof, said fluid being elevated from the receptacle and supplied to the applying roll at a p oint remote from the point of application of the work thereto.

One object of the present invention is to provide an improved machine of this general type having more room for the manipulation of pieces of Work without interference with the machine.

With this in view, a feature of the invention resides in the interposition of a novel transfer means between the uid applying member andv the supplying member which dips in the receptacle, this transfer means being substantially horizontally disposed above the area provided for the manipulation of pieces of work. By reason of this construction it is possible to provide a relatively wide separat-ion between the applying member and the fluid receptacle to allow free manipulation of the Work, while maintaining a compact and efficient design. In the illustrated construction both the applying roll and the supplying roll are frusto-conical members mounted on inclined aXes and arranged to cooperate with opposite sides of the interposed disk-shaped transfer roll arranged upon a vertical axis and disposed above the area provided for the manipulation of work. The fluid receptacle is provided with a lip extending beneath the transfer means arranged to underlie the points of co-operation between the transfer means and the supplying and applying means, thereby to keep the cement from dripping on the work or the floor.

Other features of the invention reside in novel mechanism` for controlling the quantity of fluid delivered to the applying roll by adjustably determining the relative approach of the respective rolls. construction the rolls are power-driven, and means are provided for adjusting the position of the applying roll with respect to the transfer roll without impairing the driving connection to said applying roll. As illustrated also, the applying roll and the transfer roll are mounted upon a slide normally biased to an adjustably predetermined limit in which the transfer roll is separated from the supplying device and operator-controlled means are provided for moving said slide to bring the transfer roll and the supplying device into co-operative relation.

Stilly another feature of the invention relates to a novel arrangement for supporting the fluid receptacle in the frame of the machine to allow its ready removal for cleaning.

One specific embodiment of the invention will now be described with reference to the accompanying drawings, in which Fig. 1 is a side elevation of the machine with parts broken awa-y and in section;

Fig. 2 is a longitudinal section taken through the axis of the fluid-carrying rolls and drawn on a somewhat larger scale;

Fig. 3 is a plan view of the machine with the cover removed and parts of the casing in section;

Fig. 4 is a front elevation; and

Fig. 5 is a section on the line V-V in Fig. 4 through the neck of the supply tank.

The frame 10 of the illustrated machine is provided with a socket member 12 arranged to permit the support of the machine upon the tapered upper end of a suitable pedestal 14, and an electric motor 16 is suitably supported upon the frame of the machine so that In the illustrated the main shaft 18 of said machine may be driven from said motor through a suitable Worm and gear speed-reduction mechanism 20.

The particular embodiment of the invention herein illustrated is especially designed for use in applying cement to economy insoles 22 (Fig. 2) before the lips 24 of the insole are turned and brought together. For this Work a solid applying roll 26 may be used, which is of frusto-conical form and is supported for rotation upon a shaft 28 the axis of which is inclined downwardly to the rear. The cement is supplied to the applying roll 26 from a receptacle 30 by a cylindrical transfer roll 32 supported for rotation with a vertical shaft 34 and a frusto-conical supplying roll 36 upon a shaft 38`the axis of which is inclined downwardly toward the front of the machine. The arrangement is such that the axes of these shafts are in a common plane and intersect one another. This permits the receptacle 30 to be placed at considerable distance from the applying roll 26 so as to give greater freedom for the manipulation of Work in contact with sald roll, it being understood that cement is elevated from the receptacle by means of the supplying roll 36, and delivered from this roll to the face of the cylindrical transfer roll 32, which in turn delivers the cement to an upper point upon the applying roll 26. In order that any dripping of the fluid at the points of cooperation between said rolls may be kept from soiling the Work or the floor, the receptacle 30 is provided with a forwardly extending lip 40 underlying these points but so far elevated above the plane in which the piece of work, such as the insole 22, is being manipulated that it does not interfere with said Work. )Vlien the machine is used for applying cement, to economy insoles, a corrugated Work-supporting roll 42 may be provided rotatably mounted upon the for- Ward end of an arm 44 pivotally secured at 46 to the receptacle 30. A spring 48 is arranged to hold the roll 42 in yielding contact with the lower face of the Work, and an adjustable stop 50 is provided for limiting the upward movement of said roll so that it may not contact with the cement-applying roll 26. A U-shaped bracket 52 formed upon the under side of the lip 40 of the rece ptacle serves as a guide for the forward end of the arm and co-operates with the spring 48 and the stop 50. An edge gage 54 is adjustably mounted upon the forward end of the arm 44 and is positioned in a groove 55 by means of a clamp screw.

Under certain conditions and when handling certain kinds offluid. it has been found that the quantity of fluid delivered from the receptacle to the applying roll 26 may best be controlled by adjustably determining the relative approach of the various rolls. Then,

too, it is important to be able to interrupt the supply of fluid to the applying roll when Work is not being presented to the machine. Accordingly, the illustrated machine is provided With a slidable frame 60 carrying the applying roll 26, the transfer roll 32 and driving mechanism therefor. In order to support the slidable frame 60 upon the frame 10 of the machine, the slidable frame is provided with rods 62 and 64 (Fig. 3) bolted to said frame at 66 and 68 and with a cross-bar 70 bolted to said slidable frame and slidably mounted upon a rod 72 secured in a bracket 74 by means of a set screw 76 (Fig. 1). The bracket 74 is secured to the frame '10. A spring 78 (Fig. 3) is interposed between the bracket 74 and thevcross-bar 70 on the slide of the frame, urging the sliding frame against a wedge-shaped limiting stop 80 interposed between a nut 82 u oifthe end ofthe rod 72 and the cross-bar 7,0. The position of this wedge-shaped stop may be adjustably determined by means of a spring 84 urging it in one direction and the opposing action of a hand wheel 86 threaded upon a bolt 88 attached to said stop and passing through a supporting arm 90 formed integrally with the cross-bar which is secured to said slidable frame. The rods 62 and 64 secured to the rear of the frame. 60 pass through bearings formed in lugs 92, 94 (Figs. 1 and 3) upon the frame 10 and are provided with spring 96 and 98, said springs bearing at one side against the lugs 92 and at the other side against stops 100 adjustably fixed upon the rods. Thus these springs assist the spring 78 in moving the sliding frame to its limiting position where the transfer roll 32 is carried out of co-operative relation to the fluid-supplying roll 36 so that no fluid is delivered to the applying roll 26. Operator-controlled means are provided including a trcadle-operated rod 102 adapted to move a level' 104 which bears against one of a pair of hell crank levers 106 upon a shaft 107 and engaging stops 108 upon the extended outer ends of the rods 62 and 64. This arrangement allows the operator to bring the train of rolls into (fc-operative relation so that the fluid will be carried over from the receptacle 30 to the applying roll 26 when the operator is ready to present Work to the machine and to interrupt this delivery of cement When the presentation of work is to he interrupted.

Provision is made for driving the various rolls in the train from the main shaft 18, and the arrangement is such that the driving connections are not impaired by the various ad `iustments and movements of translation already described. The supplying l'oll, 36, the shaft 38 of which is journaled in a part of the frame 10, is driven from the shaft 18 by .means of bevel gears 110. In the sliding frame 60 a countershaft 112 (Fig. 2) is provided, and this countershaft is driven from n the main shaft 18 by means of coacting spur ' gears 114 and 116, it being, noted that the spur gear 116 has a wider face than Vthe gear 114 so that it will always remain in mesh with the gear 114 as the sliding frame 60 is moved. Bevel gears 118, 120, oney upon the count-ershaft 112 and the other upon thc stud shaft 34, drive the transfer roll 32.

In order that the relative approach of the applying roll 26 and the transfer roll 32 Imay be adj ustably controlled, the shaft 28 of said applying roll and other driving connections to be described are mounted in an adjustable bracket 122 having an extension 124 which is sleeved in a bearing 126 provided upon said sliding frame 60. A stub shaft 128, journaled in the extension 124 (Fig. 2), has a pin and slot connection 130 with the end of the countershaft 112 and bevel gears 132 and 134 are pinned to the respective shafts 128 and 28 which provide a driving connection therebetween. A bolt 136 having a headed end 138 rotatably secured in the bearing 126 is threaded in the adjustable bracket 122 and may be rotated by means of a knurled head 140 and clamped in adjusted position by means of a clamp bolt 142 in the bearing bracket 122. Another clamp bolt 144 is arranged to hold the bearing 126 in its adjusted position. This arrangement provides for the adjustment of the distance between the adjacent faces of the applying roll 26 and thc transfer roll 32, thereby to determine the amount of fluid carried over from one to the other.

A cover 150 secured to the bracket 7 4 by a bolt 151 and to the frame of the machine by a bolt 152 is arranged to conceal the operating parts and is provided, as shown in Fig.

- 4. with outwardly extending lips 153 having depending doWel pins 154 tapered at their lower ends. The receptacle 30 is provided with apertured lips 156 arranged to be brought up into engagement with the lower ends of these don-'el pins in order to position the receptacle upon the machine, and this position may be maintained by means of a locking bolt 158 (Fig. 1) slidable in the main frame 10 and adapted to be operated by means of a gear-and-rack connection to a hand wheel 160. This arrangement facilitates the removal and replacement of the receptacle.

when it is desired to clean the same and insures the proper positioning of the receptacle Without excessive care [email protected] part of the operator. A supply of cement or other fluid may be contained Within a tank 162, the arrangement being that of a barometric supply in which the level 164 of the fluid in thev receptacle 30 is determined by the position ofthe outlet opening of the tank 162, and this tion within the receptacle without spilling some of the contents thereof, especially when the tank is of any considerable size or Weight, will be readily appreciated. Accordingly, means have ybeen provided allowing the tank eto be placed in inverted position directly over the receptacle before the fluid is allowed to escape therefrom. To this end a butterfly valve 168 having a projecting arm 170 is secured upon a sleeve 172 adapted to be inserted in the neck 174 of the tank 162 before the inversion of the latter, it being understood that the butterlly valve is then in closed position. The position of the sleeve 172 with respect to the neck 174 of the tank is determined by a collar 176 fixed upon said sleeve. The receptacle 30 is then provided with a slot 178 (Fig. 5) to allow the admission of the arm 170 of the buttery valve, and as the tank is inverted and lowered into position upon the receptacle, the arm 170 may be brought into engagement with a side of the slot 178 and the tank given a partial rot-ation to open the butterfly valve. and then dropped immediately into position. y

It will be understood that the invention is not limited to an arrangement for applying cement to Economy insolcs since it may, with only slight modifications, be equally Well used for ehannel-cementing or for sole-inking. Fory either of these uses the work-supporting roll 42 and associated parts will be dispensed with, and when the machine is to be used for channel-cementing, a brush similar to that illustrated in the earlierapplication referred to above will be substituted for the solid applying roll 26. When the machine is to be user for sole-inking, either a solid roll or a brush may be used as .determined by the character of the work and the nature of the ink to be applied.

The novel features of the herein-disclosed means for facilitating the positioning of an inverted supply tank upon the machine are not claimed herein since they are claimed in divisional application Serial No. 344,060 filed March 2, 1929.
