This invention relates to a device for automatically feeding and guiding soles, inner soles and similar articles, where a treating operation is to take place. along the edge, as for instance, by cutting into said edge, spreading the channels produced, etc. This operation is to take place at a certain distance from the very edge of the articles.

In the known machines for these operations,

the article had to be guided by hand, since the feeding device was not automatic. A hand feed device leads to a non-uniform. treatment of the article itself. The output of the machine was relatively small.

The sole with a channel spread therein must then be supplied with a coating of dye or paint before it is sewed onto the upper. applied on the side of the sole which is turned away from the channel, so that the finished shoe should not display an uncolored sole or should show the welt secured thereto.

This entire operation is carried out in a perfect manner due to the provision of an automatic feeding and guiding device applied to those machines which perform the edge operations on soles, inner soles and similar articles and at the same time this feeding device appliesthe coat of paint or dye. The sole or inner sole is advanced by this feeding and guiding device to be operated over its entire circumference and the coating of paint is applied to that side which is turned away from the side of the operation.

The device of this invention may be applied to bodiment in association with a spreading machine" to which, however, the use of the invention is not to be limited.

Fig. 1 is a cross section, parts being in elevation, of a spreading machine, combined with ,a 'p aintapplying device, to which my present invention has been applied, the principal attachments comprising my invention being shown in elevation and the shoe sole being presented with the toe tip under the spreading tool.

Fig. 2 is a detail top plan view of the mechanism shown in Fig. 1, with: the spreading tool removed and the sole fed around to a position 90 from that shown in Fig. 1.

Fig. 3 is a plan view of the painted sole.

Fig. 4 is a detail perspective section of the sole on an enlarged scale.

This paint is- (Cl. 12-1'l) The device illustrated is mounted on a'bracket l which is pivotally secured to the frame l5 of a known channel-spreading machine Fig. 1. The

'driving shaft 2 is mounted in the bearing bush- 3 in the base-plate I. This shaft serves to impart movement to the feeding device. Secured to one end of the shaft is the bevel pinion 4 which meshes with a second bevel pinion 5, fixed to the shaft 6 mounted in the bearing bushes l and 8' fitted in the bracket l.-

Mounted on the upper part of the shaft 6 is'a known feeding implement 9whichpresents on its convexly curved fa'ce numerous indentations 9 for the purpose of increasing the friction between the implement and the sole. The feeding tool is rotated during operation, while it is pressed against the lower surface of the sole ID (by action of spring M). It, therefore, has a tendency to impart a rotary movement to the article and in doing this, it presses the article in a direction towards another tool as, for-instance, the spreading tool l2.. This spreading tool is mounted in a known way on the shaft l3 of the spreading machine. The feeding tool 9 is urged in a'direction towards the article ID and towards the spreading tool l2 by means of a helical spring I 4 which is inserted between the bracket I and the frame of the machine.

The spreading machine also is provided with a bracket Hi. This bracket 16 supports the fixed guide 24 by means of a nut 23. The feeding tool 9 while acting on the article lllhas a. tendency to rotate the article inthe direction of the feeding tool. ,This rotation is prevented owing to the fixed guide 24 which is in the path of the rotary movement of the article. Since, however, the feeding tool 9 during its rotation continually acts upon the article Ill, there is produced a resulting advance movement in the direction to-" Wards; the spreading tool l2. The fixed guide 24 determines the distance at which the spreading tool acts on the article, that is, the distance between the contour of the article and the point of action. The fixed guide 24 is adjustable with respect to the rotary feeder 9. The bracket I6 of the spreading machine also supports, rotatably, the arm I! as shown in Fig. 2. This arm is under control of the spring 2| which is interposed'between the swinging arm I! and the pin 22. The arm l1, carries at its free end a guide rollerl8 and, adjacent thereto, the roller 20. The arm I! and roller l8 are mounted on a screw stud I9. During this positively enforced movement of the article ID, induced by the'rotation of the feeder 9 and by the presence of the adjusted The feeder tool 3 also is equipped with the spur gear 25, which engages the pinion 26, this last I named pinion being fixedly united with the paintapplying roller 21. The pinion 2B and paint roller 21 are suspended from the cover 29 by means of the universal joint 28. The roller 21 may oscillate about the universal joint 28 within certain limits and may adapt itself to the broader or narrower form of the sole. Upon opening the cover 29, paint roller 21 also will be removed so that the structure can readily be cleaned. The paint roller 21 is mounted onball bearings 3|; at the circumference of this roller 21 there is positioned resilient and porous material 32 by means of which the color is transmitted from roller 33 to feeder 9 and by means of which the roller 33 is rotated. This roller is provided with a bearing bushing 35 on a stationary shaft 36 3. The feeding tool then transmits this paint to" the article ID at the margin a, Figs. 1, 3 and 4. The painting or dyeing operation can be com bined with the feeding and spreading operation, but it is not absolutely necessary. The device may be employed even without this particular dyeing device. I

Therod 39 extends to a treadle whereby the feeding tool 9 may be pulled away from the spreading tool I2 when it is desired to insert a new article.

The present device, therefore, renders the accuracy at which the work is being treated entirely independent of the shape of the article. This invention, therefore, constitutes an advance in the art of feeding and guiding of soles and other like articles which have an irregular contour. It is also an advantage to combine the feeding device with the paint-applying device. In this manner a manual operation may be entirely dispensed with and the product obtained will be superior in appearance. Much time is saved in this manner. 1

A rest 24 may be provided on which the rand may lie while the sole is being fed.

I claim: r
