DAVID A. MOYER, OF BIRDSBORO, PENNSYLVANIA, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OF PA'IERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

MACHINE FOR SHAPING UPPERS OVER LASTS.

To all whom it may concern.

Be it known that I, DAVID A. Mornn, a citizen of the United States, residing in Birdsboro, in the county of Berks and State of Pennsylvania, have invented certain Improvements in Machines for Shaping Up pers over Lasts, of which the followingdescription, 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 uppers over lasts, and more particularly tomachines having means for laying the margin of the upper inwardly over the bottom of the last. The invention is herein shown in its application to a machine provided with means for pulling the upper over the last and means for lasting the toe of the shoe, but it will be understood that in many of its aspects the invention is not limited to combined pulling-over and lasting machines.

An object of the invention is to improve the operation of overlaying means upon a shoe; and with this and other ends in view, a feature or the invention consists in novel means for controlling the relation between the overlaying means and the shoe in the overlaying operation. The invention has important advantages as applied to an organization wherein the resistance encountered in the overlaying operation may cause a relative pressure relaxing movement of the shoe and the overlaying means in a direction transverse to the plane of the last bottom. Such an organization 18 shown,

tor example, in United States Letters Patent- No. 1,280,613, granted on October 1, 1.918,

upon an application of Orrell Ashton, wherein facility in positioning the toe wipers relatively to the shoe is afforded by a yielding support which permits the wipers to be tipped in directions transverse to the plane or the sole as the operator advances and places them in position for their operative movement over the shoe. In order to prevent the wipers in their overwiping operation from tipping unduly in response to resist ance or" the Shoe materials, and to insure effective overwiping pressure, the wiper carrier in the construction herein shown has means for engaging the shoe on the sloping at Application filed August 24, 1920. Serial No. 405,632.

end or top face of the toe to render the shoe effective with a wedging action serving to prevent the wipers from relaxing their pressure on the upper and it maybe also to force the wipers toward the plane of the sole and thus to increase their overwiping pressure as they are advanced over the shoe. Insurance'is thus afforded that the wipers in their advancing and closing movement shall wipe the margin of the upper .materials firmly over the feather and against the shoulder or rib of the sole and also draw In a further important aspect, as applied to an organization in the use of which the overlaying means is positioned manually in relation to the shoe prior to its operative movement, a feature of the invention consistsin novel means to assist in positioning theoverlaying means in the proper relation to the shoe. In the construction shown the means provided for engagement with the top or the toe as above described, is adapted i to be manipulated by the operator as headvanoes the wipers into engagementwith the shoe to assist in steadying the wipers and in bringing them to the proper overwiping plane, and it may be also to press them toward the plane of the last bottom after they have been advanced slightly over the edge of the sole to insure that both the wipers and the margin of the sole shall lee-positioned in the proper relation to said plane in the overwiping operation.

While the invention is herein'illustrated in its application to a machine of the type shown in said prior Ashtonpatent, it will be understood that no restriction is thereby implied with respect to the field of utility of the invention. It will also he understood that while the invention is illustrated in its application to turn shoe work, it is not thus limited in utility, and the term sole is accordingly used herein in its generic sense as applicable-to the'insole of a welt or other type of shoe as well as to the sole of a turn shoe.

The above and other features of the invention, including certain details of construcpanying drawings and pointed out in the appended claims.

In the drawings:

Fig. 1 is a view in side elevation of the head portion of the illustrative machine,

Fig. 2 is a perspective view of a portion of the toe wiper mechanism, and

Fig. 3 is a view substantially in side eleva tion, with parts in section, further illustrating the use of the invention.

Since the features common to the construction herein shown and to prior machines of the illustrative type are shown and described in detail in prior patents including the-patent above mentioned, said features will be referred to herein only in as far as is necessary for an understanding of the invention.

Machines of this type include in their organization a toe gripper 2 and opposite side grippers a connected respectively to updraw levers 6 and 8 which are operated by cams on a cam shaft 10 to seize and pull the upper against the resistance of a sole rest 12, whereupon the machine comes automatically to a stop to permit inspection and any necessary adjustment of the upper. Upon a subsequent starting of the machine, shoe supporting devices mounted on arms 14 are swung inwardly to operative position, and

operative movement is then imparted to mechanism mounted on arms 16 and 18 for overlaying and fastening the margin of the upper at the toe and at the opposite sides of the forepart of the shoe, For overlaying the upper at the toe the machine has end cinbracing wipers which may be of any suitable construction and are herein shown as constructed substantially as shown and de scribed in United States Letters Patent No. 1,406,260, granted on Feb. 14 1922, upon an application of Bernhardt Jorgensen. These wipers are supported on the front arm 16 and are advanced and closed in a well-known manner by movements of the front and side arms 16 and 18.

In the use of machines of this type the toe gripper is released and the wipers are advanced and tipped manually to position them in engagement with the upper in the proper overwiping plane while the machine is at rest after the upper pulling operation and before it is started to eflect the overlayirg and fastening operations. In order to permit such manipulation of the wipers, they are mounted, as explained in said prior patents, upon a wiper support or carrier 22 which has a lengthwise slot 24 to receive a pin 26 projecting downwardly from the front arm 16, and a spiral spring 28 bears upwardly against the carrier to hold it in position while permitting it to be tipped and advanced into engagement with the shoe to position the wipers in the proper relation to the plane of the sole. In the subsequent operation of the arm 16 the pin 26' is advanced along the slot 24 until the tackers 29 arrive in operative relation tothe wipers, and the wiper carrier is then advanced to force the wipers rearwardly over the shoe bottom substantially simultaneously with their inward closing movement at the sides through the operation of the arms 18. As shown in the prior patents, the wiper carrier 22 is adapted to support different wipers at its opposite ends, for example, right and left wipers, and to be turned about the pin 26 to position either set of wipers for operation on the work.

F or the purposes of this lllVQlltlOn there is secured at each end of the wiper carrier 22, under the respective wipers, a bracket 30 having a depending arm which supports a device for engaging the sloping end or top face of the toe of the shoe to assist in positioning the wipers and in maintaining them in their proper wiping plane. This device comprises a slide 32 mounted for upward and downward movement on a plate 83 adjustably secured on the depending arm of the bracket 80, the plate having a pin 34: which extends through a slot 35 in the slide and has head which overlaps the slide. T he slide 32 is provided with o-utturned ears 36 and 37 to receive and guide a holder on which is mounted a roll 40 for engagement with the sloping top face of the toe of the shoe. The holder 38 comprises a stem projecting downwardly through the lower car 36 and having an upper end portion shaped to fitin a rectangular recess in the car 37 to prevent turning movement of the,

holder. Between a shoulder on the upper end portion of the holder 38 and the lower ear 3G is a spring 42 which tends to force the holder upwardly and maintains it normally at an upper limit of movement determined by engagement of a. pin ll with the car 36. The slide 32 is provided on its opposite sides with flanges which partially embrace the depending arm of the bracket 30 and are provided with rack teeth in engagement with a series of gear teeth formed on flange extensions d6 of an operating member .48 which is mounted on a pivot 50 supported on flange extensions of the plate 32). The member a l-8 has a depending flat plate adapted to be engaged by the thumb of the operator to turn the mcn'zber about its pivot and through the gear and rack teeth to force the slide 32 upwardly and press the roll ll) against the shoe. A clamping bolt 52 e;- tending through a slot in the plate 33 permits this plate and the parts supported upon it to be adjusted upwardly or downwardly and serves to hold the parts in adjusted position.

in the use of the above described construction the operator, after the machine has come to a stop with the upper held under tension, releases the toe portion of the upper,

from the toe gripper, and by grasping the depending arm of the bracket 30 advances the wipers into engagement with the shoe, tipping the wiper carrier 22 as required in order to position the wipers in the proper,

relation to the plane the shoe bottom for the overwiping operation. As the operator grasps the bracket 30 and advances the wiper:

member 48 and the connected roll the operator is also assisted in bringing the wipers down to the proper wiping plane after they have been advanced, for example, slightly over the edge of the sole. By the use of this mechanism the margin of the sole may thus be readily pressed vdown into the proper relation to the bottom of the last in case it may have been turned up slightly from the last, and both the sole and the wipers may be positioned in proper relation to the last to insure a. tight and effective overwiping of the upper inthe operative movement of the wipers. Having positioned the wipers in their proper plane with the assistanceof the .toe engaging means, the operator retains his hold on the bracket 30 and on the member 48 during the second stage of the cycle of the machine in whichthe overlaying and fastening operations are performed The roll 40 is thus held yieldingly against the sloping face of the toe as the wiper carrier receives its forward movement to advance the wipers over the shoe and renders the shoe effective with a wedging action tending to force the wipers downwardly toward the plane of the sole as they are advanced over the shoe, insuring that the wipers shall be advanced in such relation to the shoe as to wipe the upper tightly and firmly over the feather and against the shoulder of the sole. As the wipers complete their operative movement the fastening tacks are driven and the parts of the machine are then returned to starting position and the shoe is released.
