BOURN, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR TO' UNITED SHOE MACHINERY CORPORATION, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY roxme-onmen'rme' MACHINE Application filed April 30, 1924, Serial No. 709,998.

This invention relates to machines for applying a coating to a peripheral surface of a shoe and is herein illustrated as embodied in a machine for applying a stripe of cement to the foxing area of a shoe.

applying the cement necessary for securing.

this foxing strip is known as foxing cementing, and in order to produce work of a satis factory character it is necessary to make the stripe of cement of a practically uniform width such that it will be substantially co-extensive with the foxing strip. If the cement falls short of the foxing strip the latter will not be firmly attached, and if it extends be yond the foxing strip it creates a disfiguring blemish upon the work which must be removed as a separate operation. A machine for performing this work is illustrated in Letters Patent of the United States No. 1,387,?64, granted Aug. 16, 1921, upon my application, in which a shoe is rotated past a cement applying device under the guidance of a pattern.

An object of the present invention to pro- I ride an improved machine of this character by means of which a coating of uniform width may be more accurately and rapidly applied to the foxing area of a'slioe.

In rotating a shoe past a cement applying device which is maintained in a substantially fixed position, it is necessary to impart a lateral to-and-fro movement to the shoe as it is rotated in order to keep the shoe with its irregular outline in contact with the applying device. In accordance with a feature of the invention, novel means are provided for rotating a shoe support and imparting to said rotating means a to-and-fro movement, positively to present the shoe to the applying device. As herein illustrated, the shoe is mounted upon a rotating spindle pivotally supported in a slidably mounted'carriage and cams are provided for positively moving the carriage toward and away from the cement ap- Renewed March 13, 1929.

plying device as the shoe is rotated with the.

spindle.

Still another feature of my invention resides in the provision of means for controlling the relative height of the work and the applying means as the work is rotated to present all sides thereof to the applying means. The desirability of such an arrangement will be obvious when it is realized that most shoe lasts are made with the heel portion of the last at a level different from that of the ball or toe portion'of the last, and further that commonly the shank portion of the last is recessed to a level different from that of either of the before-mentioned portions. In the illustrated inachine, means are provided for controlling both the cement applying device and the work, said means including cams rotated in timed relation to the mechanism which controls the rotation and the to-and-fro move- These and other features of the invention will be described with reference to the accompanying drawings in which,

F'gure l is a side elevation-of my improved shoe surface coating machine.

Figure 3 isa perspective View of the carriage member removed from the frame.

Figure i is a vertical section through the carriage.

Figure 5 is an end view of the cam-drum also showing a cam for lifting the fluid-applyin g device.

lVith reference to the drawings, the machine has a frame 10 comprising superposed spaced-apart guides 11 and 12 the adjacent faces of which are recessed longitudinally as at 13 a'nd'14. A work supporting carriage member 15, see Figure 3, is provided with central guide protuberances 1G and 17 for spectively in these carriage guides 11 and 12.

In this carriage is mounted a vertically-disposed shaft 18, the lower end of which is provided with a roll 19 which pro ects into a groove 20 forming two parallel cams in a drum 21, while a lower mounting plate 22 is secured to the upper end of this shaft. This plate 22 supports a second or upper plate 23 on which latter is mounted the work-carrying last 24. There is thus provided a holder for a shoe which is rotatable about an axis extending heightwise of the shoe.

The lower plate 22 is provided with three rounded knobs or projections 25 which loosely engage corresponding openings 26 in the upper plate 23, whereby the plate 23 may be tipped relatively to the plate 22 when low portions of the contour of the shoe, such as at the shank, are encountered. This tipping may be accomplished alternatively by either of the short cams or raised portions 27 on a cam-drum 21, see Figure 2, through either of the headed pins 44 loosely mounted in the carriage l5 and arranged to be brought into engagement with the under side of the plate 23 to tip it upon the knobs 25 so as to raise the work at desired points and to tilt it about an axis extending widthwise of the shoe while its rotation continues. The shoe to be coated is treated while still upon its last 24.- which is detachably mounted in any suitable manner upon the upper plate 23. The shoe or work 28 to which is to be applied a narrow stripe of cement along the foxing portion 29 thereof is moved by mechanism, to be later described, past a member I for operating upon the foxing area, illustrated as a brush 30 which is supplied with cement from a reservoir or tank 31, the quantit of flow from which is regulated by a va ve 32.

In order to impart a continuous turning movement to the shoe 28, I have mounted a worm gear 33 on its driving shaft 18 and I impart a rotating mot on to this gear and shaft from a main shaft 34 through gear 35, elongated sliding pinion 36, pinion shaft 37 and worm 38, which causes the shaft 18 and the work to rotate at a constant speed in properl timed relation to the drum 21.

nasmuch as a shoe is not round, presentationof its foxing area to the relatively fixed brush 30 requires movement of the carriage 15 and the work 28 longitudinally as the work rotates. Therefore I simultaneously rotate the drum 21 through the main shaft 34 in time with the rotation of the work and the groove 20 in the cam drum cooperates with the roll 19 to impart a longitudinal motion to the carriage 15 and so moves the elongated work longitudinally as it rotates in order to keep its surface in contact with the brush.

By this construction, the longitudinal movement of the carriage and work is positive in both directions both towards and from the brush so as to positively present the surface of the work to the brush as the work is carried past the brush.

It will be observed that the bottom of a tennis shoe isnot perfectly flat and accordingly the foxing area just adjacent thereto necessarily is irregular and lower in some parts (when inverted), such as the shank and heel, than at the toe. In order, therefore, to provide for the difference in level between the toe and the heel portion ofthe foxing area, means are provided for effecting a relative movement heightwise of the shoe between the cement applying brush 30 and the foxing area. To this end the shoe is tipped so as to adjust its level relatively to the brush and to raise its lower portions as the are presented to the brush in which case tlie cam portions 27 on the drum, by contacting with the pins 44 will engage the under side of the plate 23 and raise one end or the other of the work to the desired level relatively to the cement applying brush at exactly the desired time.

In other instances, instead of raising the work, I also provide a cam 41 on the end of the drum 21 which engages a roll 42 on a pivoted bar 13 on which rests a vertically slidable spindle 39 carrying at its upper end the cement receptacle 31, whereby at the proper time this cam 41 will serve to impart an up and down movement to the brush 30 through spindle 39 and the receptacle 31, to cause the brush {1L curately follow the outline of the foxin g portion 29 of the shoe. The weight of the cement receptacle 31 will hold the lower end of the spindle 39 upon the bar 43 which is pivoted at its outer end to the frame 10 and is guided at its inner end between depending pins 45 (Fig. 5).

In some instances, it is found of advantage in order to lay the cement properly, to cause the brush portion to yieldably press against the side of the shoe, and this is accomplished by mounting the brush 30 for swinging movement about the axis of the spindle 39, means being provided for yieldably holding the brush in operative relation to the work to accommodate itself to irregularities in the work. In so doing I use a spring 40 on the spindle 39 constructed and arranged to resist rotation of the spindle in one direction thereby to regulate the pressure of the applying surface of the brush as the brush is caused to press. against the side of the shoe.

My improved device is very simple in construction and is effective in its operation and by its use cement or other fluid may be automatically applied to the surface of the shoe.

Cement applying machines embodying my invention may be connected to be operated in batteries of any desired number and suitable stop attachments, not shown, may be contacle 31 has been filled with cement and a shoe has been mounted upon the plate 23, which is tiltably supported upon the lower plate 22, thereby to permit heightwise movementof the shoe, power is then supplied to the shaft 34 which rotates the shoe to carry the foxing area past theapplying brush which is yieldingly held in contact with the shoe. As the shoe is rotated the work supporting carriage 15 is positively moved laterally toward and away from the cement applying device by the cam groove 20. Combined with this lateral movement is a. heightwise movement of the shoe occasioned by the tilting of the shoe by the rods 44 when the cam projections 27 underliethese rods and lift them. Provision may also be made for the heightwise movement of the cement applying device by means of the cam 41 acting through the connections already described. it being remembered that the whole object of this relative heightwisc movement of shoe and applying device isto apply a uniform coating of cement to the whole of the foxing area and to keep this coating or stripe substantially uni form in width so that the upper edge of the coated portion will coincide with the upper edge of the foxing strip to be applied thereto.

It will be understood that, in various aspects, the invention is not limited to embodiment in the particular type of the machine shown and described or to the performance of the particular operation referred to. AC- cordingly, the scope of the invention is to be determined by the broadest construction of the terms of the claims which is permitted by the prior art.
