ORRELL ASHTON, 0F LAWRENCE, MASSACHUSETTS, ASSIG-NOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

SHOE-SHAPING- MACHINE.

Specification of Letters Patent.

Patented Mar. 12, 1912.

To all whom it may concern:

Be it known that I, ORRELL AsI-rroN, a citizen of the United States, residing at Lawrence, in the county of Essex and Commonwealth of Massachusetts, have invented certain Improvements in Shoe-Shaping Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to machines for shaping shoes and particularly to machines for beating a shoe to conform the upper to the contour of the last.

An object of the invention is to provide improved shaping means.

The invention is herein shown as embodied in a machine having means for beating the bottom of a shoe at and adjacent to its edge and means for shaping the side of the shoe. The latter means includes a rest or abutment against which the shoe is guided and turned in holding it to the bottom beating tool. This resting means includes a stationary or rigid portion and a yielding portion to either of which the shoe may be presented, the bottom beating tool being long enough to permit the shoe to be held against different portions at different times. The yielding portion of the resting means is capable of being forced back by the work into the field of a rotary actuator from which it will then receive forward impulses driving it against the side of the shoe. This member then becomes a side beating tool. It does not necessarily leave contact with the work between its forward impulses or beats, but preferably rests continuously in contact with the shoe while the latter may be fed along against it. The blows thus imparted to the shoe are light and rapid and in the nature of quick sharp pressures which do not mark or injure the upper.

A Very important feature of this invention consists in providing shoe resting means having a portion normally at rest and adapted to be rendered operative by the workman to beat the shoe. It is characteristic of the preferred construction that the shoe resting means can be started to beating the shoe at any time while the machine is running by applying pressure against it through the work. Preferably the resting means will include a stationary portion against which the work may be pressed without starting any beating movements of the resting means. It is also characteristic of the illus trated construction that it includes two heaters one of which may be continuously driven and the other of which is normally at rest and can be rendered operative or inoperative during the progress of the shoe.

shaping operation as the conditions of the work require or as portions of the shoe are reached which require the treatment of the second beater. In shaping the toe portion of the shoe the side beater will usually be rendered operative by increasing the pres sure against the yielding portion of the resting means until it is brought into the field of its actuator. As the shank of the shoe is approached where side beating is not needed the pressure will be relieved and the side beating tool will serve merely as a work guide or the point of guiding contact with the resting means will be transferred from the stationary to the yielding portion and back again as the requirements of different portions of the shoe have to be dealt with.

These and other features of this invention, including certain details of construction and combinations of parts, will appear in connection with the following description of the illustrated embodiment of the invention and will then be pointed out in the claims.

Figure 1 is a plan view. Fig. 2 is a vertical section.

A suitable rotary carrier is indicated at 1 provided with rods 2 upon which are loosely strung rollers 3 adapted to be carried around by the carrier and held outwardly upon the rods by centrifugal force to strike a yielding rolling blow upon the shoe bottom. Located above the bottom beating tool in position to guide and rest the side of the shoe being treated by that tool is the side rest 4, which comprises end portions which are stationary or rigidly attached to the machine and an intermediate portion 5 which is movably supported. As shown, the section 5 is a plate attached to a slide 6 arranged to move in an inclined guideway and of a sufficient mass to hold the section 5 normally in its outermost position. A spring 7 may be added for holding the section 5 outward. This section 5 of the edge resting means together with its carrier is adapted to be pressed backwardly for placing the dependthe tool 5 and carrier 6 can be moved backwardly is determined by an eccentric 15 carried by a screw 16 which projects from the frame of the machine through a stop plate 18, as shown in Fig. 2. The beating tool 5 or the portion thereof which contacts with the shoe is shaped in accordance with the contour of the work to be treated and is shown as connected by a dove-tail joint to the carrier 6 to permit its convenient removal and the substitution of a tool having a diiferent work engaging face. The lower end of the beating tool 5 is arranged to extend substantially to the path of the bottom beating rings 8 so that said two parts may cooperate to beat the bottom and the side face of the shoe substantially at and adjacent to the edge of the shoe. The bottom beating tool is preferably a roll of suflicient length to permit the shoe to be presented upon different portions of the roll with its side face rested against either the stationary portion of the edge resting means or against the yielding or beating portion thereof.

In the use of the machine the shoe will be presented as indicated in Fig. 2 with its bottom face in posit-ion to be beaten by the rings 3 and the shoe will be rested and guided against the members 4 or 5. The

- portion 5 will yield against the pressure of the shoe and when suflicient pressure has been applied to overcome the spring 7 and the weight of the parts the slide 6 will be forced into the pat-l1 of its actuator for establishing operative connection between that actuator and the beating tool 5. This operative connection will continue and the tool be caused to beat the side of the shoe as long as the pressure continues. It will be understood that the side beating tool can thus be rendered operative or inoperative at any time at the will of the operator and in practice this will be done in accordance with the requirements of different portions of the shoe. .The tool 5 will ordinarily be caused to beat the side of the shoe while the toe is presented against the resting means, but as the shank of the shoe is approached where the upper does not require to be beaten against the side of the last the pressure against the beating tool will be relieved or the shoe will be guided against the stationary portions of the resting means.

Having explained the nature of this inwithout interrupting the operation of the machine in beating a shoe.

2. A machine of the class described, having in combination means for treating the bottom of a shoe and means occupying continuously an operative position for resting the side of the shoe during the bottom treating operation, said latter means comprising a rigid member and a yielding member arranged to be used at the will of the workman without causing any substantial change in the operation of the bottom treating means upon the shoe.

8. A machine of the class described, having in combination, means for treating the bottom of a shoe, and means for resting the side of the shoe during the bottom treating operation, said bottom treating means comprising a beating roll substantially longer than the width of the shoe to permit a shoe to be presented to different longitudinal portions thereof, and side resting means having different characteristics in the portions adapted to be engaged by the shoe in different positions on the roll.
