UNITED STATES PATENT OFFICE.

EDWARD EBICKSON, OF BEVERLY, MASSACHUSETTS, ASSIGNOR. TO UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

Application filed July 13,

This invention relates to fluid-applying machines and is illustrated as embodied in a cementing machine for applying cement to the foxing areas and adjacent bottom surfaces of shoes.

In the manufacture of rubber soled canvas shoes, for example, it is customary, prior to the attachment of the sole to apply a band of cement to the foxing area of a shoe and to 1o the adjacent surface of the bottom of the shoe in order to attach the sole and the foxing strip joining the sole to the canvas upper. Although machines have been devised for performing this work, the operation is still extensively performed by hand and requires considerable skill because of the necessity of accurately limiting the upper. edge of the band of cement applied to the foxing area so that no cement will show above the foxing strip in the completed shoe thereby to mar its appearance.

An object of the present invention is to provide an improved machine by means of which cement may be applied quickly and accurately to the foxing area and the adjacent bottom area of a shoe. Accordingly, in order that an operator may present successive shoes easily and quickly to the machine, the illustrated machine is' provided with an applying brush rotatable about an inclined axis and arranged to apply cement to the foxing area of a shoe presented thereto, means being provided adjacent to said applying member for limiting the spread of the brush bristles thereby to determine the upper edge of the band of cement applied to said foxing area. In accordance with features of the invention and as shown, the applying member consists of a rotatable brush comprising two frusto-conical sections brought together to form a peripheral groove, said brush being exposed at its lower side for the application of work so that an overhanging under portion of one face of the grooved brush will coat the foxing area while an adjacent, substantially vertical portion of another face of the grooved brush will coat the adjacent area of the bottom of the shoe, and the brush is provided with means for limiting the upper edge of the band of cement applied thereby. Still other features of the invention relate to the construction and arrangement of the applying member and of the mechanism for supplying and controlling the supply of cement thereto.

FLUID-APPLYING MACHINE 1926. Serial No. 122,150.

One specific embodiment of the machine is shown in the accompanying drawings, in which Fig. 1 is a side elevation of the complete machine with parts broken away and in section;

Fig. 2 is a front elevation of the head of the machine and Fig. 3 is a perspective view of the applying brush and the device for supplying cement thereto and controlling the quantity of cement supplied.

To facilitate presentation of work to the machine, an applying member 10, illustrated as a rotary brush, is mounted onan axis inclined to the horizontal and extending down- {wardly away from the operator at the front"70- of the machine so that a shoe 12 may conven iently be presented to brush as it is moved in a substantially horizontal direction, as indicated by the arrow in Fig. 3, said brush being positively rotated by an electric motor 14 and supplied with cement from a receptacle 16. The applying member 10 and its associated mechanism are supported in a frame 18 attached to a block 20 which may be adj ustably secured at any desired elevation, in accordance with the stature of the operator, by means of a wedge bolt 22 upon a standard 24. For the sake of convenience, this standard 24: is supported upon a base 26 provided with castors 28 so that it may be readily moved about from one place to another.

The. applying member 10, preferably and as illustrated, is made up of two frusto-conical brush sections oppositely disposed so that their peripheral conical surfaces intersect and form a groove around the brush to receive the foxing .area and adjacent bottom portion of a shoe. The brush sections, together with a disk 30 above the base or top face of the upper section, are clamped between end plates 32 and 34 upon an inclined shaft 36 rotatably mounted at the front of the frame '18. In order to facilitate the removal of the brush for cleaning, it is held in position as determined by a spacing collar 35 upon the rotating shaft 36 by means of a bolt 38 passing through the interior of said shaft and retained therein by means of a nurled nut 40 at its upper end. B In view of the shape of the applying brush .10 and its disposition upon the described inclined axis, the lower portion of the forward face of the upper frusto-conical section of the brush is disposed in a plane approaching the horizontal and, overhanging the work, is exposed for the application of cement to the foxing area of a shoe held as illustrated in the drawings. It should be noted in this eonnection'that the upward deflection or spread of the bristles under pressure of the shoe is limited by the disk 30 so that the spread and hence the upper edge of the band of cement applied to the foxing area is determined by this disk and the edge of the area coated is accurately defined. At the same time the other frusto-conical section, the forward face of which is disposed in a substantially vertical position, is arranged to apply cement to theadjacent area of the bottomof the shoe-while cement is being applied to the foxing area. 7

Rotation, of the applying brush is effected. by means of bevel gears 42 and 44 connecting the shaft 36 to a shaft 46 which isconnected, by spur gears 48, 50 and 52, within a housing 54, to a drive shaft 56 connected to the electric motor 14 by a worm drive 58. It will be noted that the shaft 36 is retained in the frame by the bevel gear 42 "clamped thereto as the latter rests upon the upper surface of a bracket 60 upon the frame 18. A protecting cover 62 is provided for the gears 42 and 44, said cover being hinged at 64 to the upper,

forward end of the frame and held in positionby a nut 65 so that it may be readily opened to obtain access to said gears.

Cement is supplied to the applying member 10 at a point spaced a substantial distance from the point of application of a shoe thereto by the upper. portion of the edge of a transfer disk 66, tobe later described, dip-.

ping in cement contained within the fluid receptacle 16 to which receptacle cement is supplied at a constant rate and held at the desired level, as indicated by the line 68, by a barometric feed can 70 (Fig. held in inverted position within a receiving opening 72 and provided with a threaded nozzle 74 the position of which may be adjusted to determine the height of the surface of the cement within the receptacle 16. The receptacle 16 is provided with an integral lug 76 (Fig. 1)

having vertical openings for the reception of tapered dowel pins 78 secured in a portion of the frame 18. After the receptacle has been positioned upon these dowel-pins, it is supported in this position by means of a swinging bracket 80 (Fig. 2) provided with an operating handle 82 and pivotally mounted upon a collar 84 adjustably'secured upon the standard 24 by means of a clamp bolt 86. Inasmuch as it is customary in cementing machines to remove the receptacle at regular intervals for cleaning, the organiaztion described facilitates this operation and insures I the proper repositioning of the receptacle upon the machine without excessive care. on the part of the operator.

It should be noted that the receptacle 16 is so shaped that it underlies the whole of the transfer disk 66 and a portion of the brush,

and particularly the upper portion of the 66 move in opposite directions so that the brush effectively removes the cement delivered thereto by the periphery of the disk. It will be noted also, by an inspection of Figs. 2 and 3, that the disk 66 is a substantially cup shaped, frusto-conical member having its I periphery specially formed to provide intersecting conical surfaces forming around the forward edge of the cup a ridge which cor responds in shape to the groove in the applying brush. In the preferred form of the invention herein illustrated, the transfer disk is arranged upon an axis intersecting the axis of the applying member 10 and delivers cement to the highest point of the applying member. It will be understood, however, that this exact relation is not essential to a proper operation of the machine no matter how desirable it may be from the standpoint of giving maximum freedom of movement of the work with respect to the applying brush.

In order to control the amount ofcement delivered by the transfer disk 66 to the applying member 1(), suitable fluid-controlling means are provided-in tlr e form of scrapers. To this end a fixed scraper plate controlling the outer frusto-conical surface upon the disk is adjustahly supported by means of a hracket 92 upon the frame of the machine, said bracket being held in position thin-con by means of a bolt 94. In addition, another ad justahle'scraper 96 is carried at. the lower end of a pivoted arm 98 (Fig. 3) the upper end of which extends between ears 100 and 102 of a portion of the frame and is adjusted therebctwcen by means of a spring 104 and a set screw 106. By means of these two scrapers the amount of cement carried along by the transfer disk 66 from-the receptacle to the brush 10 is constantly controlled. In

addition, there is provided an operator-com trolled scraper having a blade 110 shaped completely to remove the cement from both of the frusto-conical surfaces of the transfer disk 66 when in contact therewith. Also, an

auxiliary scraper 111 (Fig. 1) contacts with upward extension 116 connected to a treadle.

rod 118 and normally held in an upward position as determined by a stop screw 120 by means of a spring 122. This spring is attached at its upper end in a bracket 124 secured to the frame 18. It will be seen from Fig. 1 that the treadle rod 118 is attached at its lower end to a treadle 126 pivotally secured to the base 26 of the machine.

The machine is prepared for use by causing the driving'motor 14 to rotate the applying member 10 and the transferring disk 66 constantly. By reason of the action of the operator-controlled scraper 110, however, no cement is carried to the brush so that there is no danger of an excessive quantity of cement being carried around by the brush to drop upon the floor or to be applied to the first piece of work presented thereto by the operator. \Vhen the operator brings a shoe into position, as illustrated in Figs. 1 and 3, he depresses the treadle 126 to remove the scraper 110 from contact with the transfer disk so that said disk elevates a fixed quantity of cement as determined by the scrapers 90 and 96 and delivers it to the groove of the applying brush 10 by which it is applied with exactitude to the foxing area of the shoe and to the adjacent surface of the bottom of the shoe. It will be understood that the operator moves the shoe along in the direction of the arrow in Fig. 3 to present the whole periphery of the foxing area to the applying brush 10 by a motion which may be quickly effected. At the same time the stripe of cement applied is limited by the disk 30 to the exact height upon the upper of the shoe to which the foxing strip is to be applied without requiring excessive skill upon the part of the operator. As any particular piece of work is completed, the operator releases the treadle 126 allowing the scraper 110 to clear the transferring disk 66. Any surplus cement carried upon the brush will be scraped off by means of the auxiliary scraper 111 and allowed to drip back into the receptacle.v
