on shoe soles.

Addendum to patent ΛΙ 94247 from June 21, 1896.

Claim 1 of Patent No. 94247 contains a method for making the sewing ribs on shoe soles, in the case of soft soles any weakening of the sole should be avoided by the rib is formed by pressing and upsetting the sole.

Claim 2 of that patent contains a tool for carrying out the method, the The main way of working is by embracing the edge of the sole and compressing it against its side face to form the rib.

In a further development of the invention is to carry out the above method (claim 1 of Main patent) instead of the tool (claim 2) a machine entered through their organs the activity of the above-mentioned tool with the achievement of the same effects, only executes in a more perfect way.

As in the case of the tools (claim 2 of the main patent), it is encompassed of the edge of the sole and a compression against the side surface of the sole, only with the difference compared to the tool, that the rigid pliers jaws for grasping and holding by rotating organs for grasping, holding and transporters are replaced, and the compression organ has a very rapid reciprocating motion Movement is imparted to this upsetting effect on the same point of the sole edge to execute several times. Such a machine is included, for example Drawing shown. Fig. 1 is a side view, Fig. 2 is a plan view of the same. Fig. 3 is an end view and Fig. 4 gives details of the operative organs with a work-in-progress sole between them.

Figures 5 and 6 show in section and in elevation the one provided with the rib by the machine Felt and leather sole.

The machine is driven by the main shaft H from the right side in FIG. 1; A conical stump T, which has a small bulge t at the inner end, is keyed onto this shaft at its left end. In front of this part T there is an adjustable guide Q with an inclined surface, which can be adjusted in a longitudinal hole q ^{1 of} the frame by means of the screw bolt q.

Shaft H is connected to the inclined shaft G by bevel gear I and bevel gear K. On the left end of this shaft G is a profiled roller G ¹ which, as is evident from the operation of the machine, brings about the advancing movement of the sole during its processing. Shaft G in turn is connected through the bevel gears L and M having a small vertical intermediate shaft, which a mounted on the shaft of the latter wheel Krumm pin F ^'2 drives through the spur gears N and Ό on which the rod E is connected. The crook can be used to

Claims (1)

Regulation of the longitudinal movement of the rod E can be adjusted. As will be seen below, the end of the rod E is one of the most essential parts of the machine. Shaft G is mounted in a part B of the machine frame that rotates at B ^1. A strong tension spring S tries to lift this movable part B in order to keep the roller G ¹ out of contact with the part T. A hook C is rotatably attached to the fixed part A of the machine frame, in which a rod C ¹ grips, which extends down to a pedal which is operated by the worker. The hook C is provided with a projection which rests against the vertical part D of the movable machine frame B. In the state of rest, the roller G ¹ does not rest on the stump T. But when the working door steps on the pedal, it pulls the shaft G downwards through the hook C, so that the roller G ¹ rests against the stump T under pressure. This is the working position of G ¹ and T in relation to one another. In order to produce the rib indicated by X in FIG. 5 on the sole, the procedure is as follows: The sole with a very small gap in its edge, which gap can be made by hand or with a suitable tool, is inserted between Roll G ¹ and stump T introduced so that it rests against the stop Q serving as a guide. The sole lies in such a way that its ^{part lying under the roller G 1} forms the starting point of the rib to be produced. If the worker has now ^{firmly clamped the sole between roller G 1} and stump T by pressing the pedal, he starts the machine. The sole pushed forward between G ¹ and T is now guided in such a way that G ¹ always remains at a small constant distance from the sole edge; this distance is regulated by the position of the guide P. During this movement of the sole between the parts G ¹ and T , the rod E makes its back and forth movement and strikes violently against the edge of that part of the sole ^{which protrudes inward from the roller G 1} , whereby the desired rib is formed on this edge. As a result of the oscillating movement of the rod E , it does not hit the edge of the sole perpendicularly, but in a curved line, so that it contributes to the advancing movement of the sole. Hence it is necessary that the swinging movement of the rod E is such that, when its end is in contact with the sole, it displaces it by the same amount as the roller G ¹ and the stump T do, otherwise it will not tear Sole would take place. Since the bar E now leaves the sole during certain periods of time when walking back, the bar must have a certain width at the front so that all points of the sole edge are hit several times in an even manner. In order to properly form the rib of the rod E, a very rapid to and fro movement must be imparted, so that it hits the sole sufficiently often with each revolution of the roller G ¹ . Since this speed of movement of the rod depends on the ratio of the transmission in the drive wheels, a change in the transmission ratio must occur here, depending on the sole material that is subject to the processing. '■■ Workers with the pressure on the pedal is raised whereby the shaft and _G: is the sole carried out so far to stop DAF -the rib formation, the läfst; the sole is released for removal. Since soles of different thicknesses are processed, one must be able to lift the rod E more or less. For this purpose it goes in its front part in a vertical guide P, which can be adjusted more or less high Guide which is attached to the guide Q. In addition, the movements of the rod E are guided by a small handle R which is attached partly to E and partly to the carrier Q., as shown in FIG . Patenτ claim: A machine for carrying out the:. In Patent No. 94247 protected process of rib formation on shoe soles, characterized by two in circulation to be set against each other movable parts (T and G'J which detect the sole in the vicinity of its edge between them, in Connection with a reciprocating rod (E), which by quickly following one another against the edge of the sole causes the formation of ribs on the sole as a result of the upsetting effect. 1 sheet of drawings.
