MACHINE FOR SHAPING THE REAR PORTIONS OF SHOE- UPPERS.

T 0 all whom it may concern:

Be it known that I, FRED RICKs, a subject of the King of England, residing at Leicester, Leicestershire, England, have invented certain Improvements in Machines for Shaping the Rear Portions of Shoe-Uppers, of which the following description, inconnection 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 use in making boots and shoes and is herein shown as embodied in a machine for shaping the heel portions of shoe upper materials prior to the lasting operation on the shoe. As shown the machine comprises inner and outer molds or formers and heel seat wipers by means of which the heel seat edge line is established and the heel seat flange is formed preparatory to lasting. One important feature of this invention consists in improved means for gaging the position of the work with relation to said molds and wipers to obtain a correctly located heel seat edge line and a correct width of heel seat flange.

Another feature of the invention consists in novel means for resisting heel seat forming pressure upon an inside mold. In an advantageous arrangement of machine to which this feature of the invention is shown as applied, the inside mold is supported with its heel seat face upward by means which permits the upper to be placed upon the mold from below. This feature of the invention provides additional supporting means movable from a retracted position into position to form a rigid support in the line of thrust of compression upon the heel seat face of the mold. A further feature of the invention consists in automatic operating means for said additional supporting means.

Another feature of the invention consists in novel outside molds. Many shoe uppers are made with back seams which are sometimes pinched in the joint connecting the two jaws of outside molds. In the illustrated embodiment of this feature of the invention, the meeting edges of the inner faces of the jaws are located at one side of the middle of the heel.

Another feature of this invention consists in improved heel seat wipers. It has been Serial No. 11,537.

found that in inturning the heel seat flange the upper at the back seam has sometimes been bunched up to such an extent that as the wipers advance the seam has been opened or a piece has been sheared off by the wipers. In the illustrated embodiment of this feature of the invention a projection is formed on the wipers which presses the upper at the back seam against the heel seat face of the inner mold before the immediately adjacent portions of the upper on either side of the back seam are so pressed.

These and other features of the invention, including certain more important details of construction and combinations ofparts, will now be described with the aid of the accompanying drawings and will then be pointed out in the claims.

Figure 1 of the drawings is a side elevation of the forward portion of a heel end molding machine embodying this invention. The general organization of said machine and those portions of it which are not shown in these drawings may be ascertained from United States Letters Patent No. 1,156,897, granted October 19, 1915 upon the applica tion of Joseph Gouldbourn at al.

The machine illustrated in the drawings comprises a frame, a part of which is indicated at 1, having the usual operating mechanism and provided at the front of its upper part with forward extensions 19 that support a cross-beam 20 from which the in ner mold 25 is supported by a member 2% forming an extension of the inner mold projecting downward into the bottom opening of the upper, that is to say, the opening which, although shown uppermost in Fig. 1, is located at the bottom of the upper when the upper is the right way up. The outer Specification of Letters Patent. Pai qgntgd N 20, 1917, Application filed Mar-ch 2, 1915. I

arranged mold comprises two interlocking formers 26, 27 which at the commencement of the operation are open to receive the heel end of the upper to be molded. The frame also carries wipers 50, for wiping inwardly the upstanding port in of the margin of the upper at the heel to form the inturn ed flange and to H'SSS the latter down upon the inner mold. These parts may be constructed and as forth in said prior specification except in the particulars hereinafter pointed out. it has been found liiiicultto place the materials accurately upon the inner mold in the desired relation thereto, and when the machine is provided with wipe-rs, unless the right amount of margin is left projecting, a flange of incorrect width is formed.

it is an object of the present invention to overcome this difficulty, and accordingly there is provided an adjustable or other gaging member located, when in operat ve posi tion, in predetermined relation to one of the molding members and in p: ion to be engaged by the bottom edge of the upper. that is to say, the edge which is lowermost when the upper is the right way up.

Difficulty has also been experienced in locating the upper upon the mold with the back seam exactl in the middle of the rear portion of the mold. in order that the said gaging member may also serve as a back seam gage it is preferably disposed centrally with relation to the inner mold.

The is formed as a finger 5 projecting rearwardly from a supporting portion 6 which depends from an arm 8 that projects from the side of the machine over the middle of the inner mold 25. Passing through the finger 5 is a screw 10 adapted to contact with the heel seat face of the inner mold so that by adjusting this screw the distance of the finger from the inner mold may be altered and thus the gage can be set to vary the upper margin left upstanding. The finger 5 is located over the middle of the nold so that if the operator locates the upper upon the mold in such a manner that the back seam is directly under the finger, it will be in correct position.

The arm 8 is clamped by means of a bolt 12 upon a sleeve 86 mounted upon a rod 80 located in bearings 1d, 15 at the side of the machine. The sleeve sea itself fixer longitudinally between the bearings so that it has no longitudinal movement, but the rod 80 is adapted to slide longitudinally in the sleeve for a purpose which will appear. The sleeve has a cam groove 89 cut in it and into the groove projects a cam roll mounted upon the sliding rod 80, the shape of the cam groove being such that as the rod slides backwardly or forwardly, when near the limit of its backward movement, the arm and therefore the finger 5 will be raised or lowered respectively.

The rear end of the sliding rod 80 passes through a boss 16 formed on av bracket 18 rigid with the machine frame and is providcd with rack teeth engaging with a pin ion on a transverse shaft 81. A second pinion 82 upon this shaft engages with rack teeth formed on another rod 3%, one end of which is shown pivoted to a reciprocating wiper-carrying frame 55 which is adapted to advance over the mold :25, thereby causing the wipers to form the inturned flange and bringing them into position to compress the rid flange, in order to provide for the angular movement of the rod 34 during the reciprocation of the frame 55, it is mounted to slide in a journal 35 which is adapted to turn vithin the bracket 18 about the transverse shaft 81. The arrangement of the parts is such that as the wiper-carrying frame moves forwardly the arm 8 and therefore the linger or gage 5 will be moved upwardly out of the path of the f aims and that when the frame is retracted the linger will again be lowered into gaging position.

The inner mold is supported from above with its sole face uppermost and with a free space extending beneath the mold to the back of the heel so that the upper can be placed on the mold from below. If, as is customary, heavy pressure is exerted by the ipers downward upon the said sole face in compressing the inturned flange of the upper, the heel end of the inner mold is apt to be displaced below its proper position. To prevent this displacement, additional supporting means is provided which is movable from a retracted position giving access to the inner mold into position to form a rigid support in the line of thrust of com pression between the wipers and the inner mold. Pivoted between lugs on the front of the machine is a short post or strut 42 provided at its upper end with an adjusting member shown as a headed screw is. and lock nut, the position of which screw can be adjusted longitudinally of the post 42. A downward projection -15 from the inner mold is adapted to be engaged by the head of the screw 44, the post being positioned under the downward projection by an upwardly projecting lug or plate 46 fixed to the rearside of the post. For the purpose of sparing the operator of the ma chine the extra labor which would be required if the said supporting means were separately operated, it is preferred that connections be provided between these means and a part (hereinafter described as the starting treadle of the machine) adapted to be located out of its normal position dur ing the molding operation, whereby the said part acts, through the said connections, to

hold the additional supporting means in active position while the compression of the margin is taking place. As herein shown the post is held normally in toward the frame of the machine by a spring 48 as shown by broken lines in Fig. 1. The post is also connected through a second spring 56 and a rod 58 to the clutch treadle (Fig. 1) of the machine in such a way that the first movement of the treadle will move the post 42 into operative position underneath the projection 4:5 and will thereafter throw in the clutch to start the machine.

The outside formers 26, 27 are of improved construction. As shown, there are two formers which are divided mainly at a point opposite the back seam. In the pres ent instance, however, the former 26 is formed with an offset portion 28 projecting laterally past the back seam and toward the other former 27 which has a corresponding recess 29. vBy this means the line of division or joint between the formers, so far as it affects the upper, is moved to one side of the usual position of the back seam so that there will be much less tendency to pinch the upper between the formers than was formerly the case.

As has hereinbefore been pointed out, the bunching up of the upper during the formation of the inturned flange is liable to occur so that plaiting takes place at the mid line of the back of the upper and over the back seam, as this is most generally placed, when the wipers are constructed as has been usual, which plaiting sometimes results in a portion of the upper being sheared off. In the present machine the end wiper 51 is provided upon its under side with a projection 52 so located that in the forward movement of the end wiper it will engage the upper at the mid line and press it down upon the inner mold 25. This insures that the plaiting of the material shall occur on either side of the mid line, so that the thickness of the bunched up upper at this point shall be less than when plaiting occurred over the back seam, as it frequently did formerly.

Having explained the nature of this invention and fully described an illustrative embodiment thereof, I claim as new and desire to secure by Letters Patent of the United States 1.
