PROCESS OF MAKING SHOES.

' Specification of Letters Patent.

Application filed June 25, 1914. Serial No. 847,179.

To all whpm it may concern:

Be it known that 1, JOHN A. KELLY, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Process of Making the following is a specification. This invention is a process of making shoes, and it involves, more particularly, an improvement in lasting, the upper whereby the procedure is simplified by the omission of certain steps considered essential heretofore, thus saving time and labor and. securing economy in the manufacture of the resulting articles. A The procedure heretofore in vogue involves, subsequent to the assemblage of the last, a channeled insole, upper, boX toe and counter, and the operation thereon of the pulling over machine by which the toe and side portions of the upper are drawn over the last, and temporary tacks are driven into the last by which the upper is retained in position on the last, the following steps from the pulling over machine, the lasted shoe is passed over to workmen known as side lasters who take the shoe in hand and by aid of pincers pull the side portions of the upper over the last to an extent determined by the final stretching of the upper at the respective side portions, said workmen driving the lasting tacks through the upper into the last; then the lasted shoe is carried to a lasting machine, known in the trade as the Idea machine, the same em bodying wipers by the operation of which the toe and heel of ,he upper are lasted in; then the shoe is placed on a rack to remain over nightthereon inorder to dry the upper and mold itv over the last; then the shoe is operated upon by a stapling machine embodying as elements thereof a throat plate and a movable anvil, the'latter operating in the channel of the insole so as to press the latter to the upper and against the throat plate whereby the upper and insole are united by wire staples, and then the welt is sewed to the shoe and the latter is finished in theusual manner.

After assemblage of the several parts and the operation thereon of the pulling over machine, the shoe when made in accordance with 'm'yprocess is subjected directly to the following operation: The respective side portions of the upper are lasted and stapled by a relative movement-between the anvil and the throat plate of the stapling machine, said side lasting being performed by pulling or forcing the side edge of the upper over the last at two points located respectively at the sides of the anvil and throat plate, and simultaneously with the side pull at the two points the wire staple is fed to fasten the upper and insole at a point intermediate the separated points of pull, the foregoing operations being repeated along the Whole side edge of the upper until the two sides of the u per shall have been lasted and stapled.

By my improvement the labor of side lasting the upper and driving the lasting tacks, and the further labor of pulling out the lastingtacks subsequent to-the stapling operation, are dispensed with, thus facilitating the work of lasting the shoe, saving time and labor, and securingeconomy in the manufacture of the shoe.

In order that others skilled in the art may understand the invention, I have illustrated one form of mechanism by which the side lasting and stapling of the shoe may be carried out expeditiously, but it is to be understood that the novelty does not reside in the particular machine herein illustrated, nor does the i .ver,tion involve a machine of a particular type for the reason that the procedure may be carried out by hand or byan equivalent machine suitable for the pur- In the drawings, 'Figure 1 is a perspective view illustratingthe insole and the upper applied to, a'last. Fig. 2 is a plan view illustratingthe operation of, pulling over an edge portion of the upper at the respective sides of the insertion of the staple fastener, and simultaneously therewith in conducting the side lasting operation in-acoordance with this invention. Fig. 3 is a vertical cross section through a part ofthe last, the upper and the insole illustrating the pulling over thrplat plate and theanvil cooperating therewit A designates a last, B; the upper, and C an insole having two channels one of which produces a rib 0 and the other a lip o.

The mechanism for conducting the side lasting and stapling operation simultaneously embodies a throat plate D, and an anvil .E, the same being relatively movable one to the other and cooperating to insert the staple fastener and simultaneously there- Patented Feb. is, was,

with to side last the upper. The throat plate D is provided with a throat d and with members D D, the latter bemg positioned on opposite sides of the throat d and versely to said channel, substantially in the.

' manner disclosed in the patent to Drey granted December '12, 1911, No. 1,011,592.

The anvil E is provided with a'toe e and with a lipe, the latter depending from the body portion of the anvil and positioned in the rear of the toe. Said anvil E is operated by mechanism substantially as disclosed in the Drey patent, and it is adapted to travel in the two channels of insole C, the toe e of the anvil coeperating with the rib 0,

Whereas the lip e of said anvil travels in the other channel of the insole so as to bear against the lip 0', said rearwardly positioned lip e of the anvil taking up some of the thrust exerted by the anvil upon the insole when pressing the last, the insole and the upper against the pulling over members D D of the throat plate.

In carrying out my invention I proceed as follows: The parts to form the shoe are assembled in the usual way, that is to say, the

insole O is tacked to the last A, the box toe and the counterare positioned within the toe and heel portions of the upper, and said upper is positioned over the last. The assembled shoe is now carried to the pulling over machine, usual in the art, and it is subjected to the operation of said machine,

so that the upperis pulled over the last at the sides and toe portion thereofat one 'operation, said pulling over machine operative to drive five tacks or temporary fastenings into the'upper, one of sald tacks being at the toe portion of the last and the remain ing four tacks being driven through the upper and the last, two on each side. Instead of passing the lasted shoe to the side lasters, or placing the shoe in the rack, as heretofore, the shoe when made in accord ance with my invention is carried from the pulling over machine directly to the staplin machine embodying the throat plate D an anvil E, and thence to the lasting machine, the wipers of which last in the toe' and heel of the upper. The operator places the last below anvil E will enter the respective channels of the insole, and by the operation of the stapling machine the'anvil is moved toward the so that toe e and lip e I lateglthe efiect of which is as folhe free portion of the upper is enthroat lows gaged by the toothedmembers DD of;

the throat plate, whereasthe insole is in engagement with the anvil, the movement of which presses the edge portion of the up-. per against the throat d of the throat plate, whereas the toothed members D D? exert pressure upon said upper so as to pull the latter over the edge and the last, this pulllng overefiect on the free edge of the upper taln'ngplace at 0pposite sides of the point of insertion of the wire in forming the staple, and said pulling over operation being efiected simultaneso ously with the insertion and clenching of the staple. The anvil is nowgwithdrawn and the position of the shoe iscshiftedso as to present a fresh surface to the anvilthethroat plate, whereupon the operations are repeated until the side lasting of the upper is finished. After completing the side lasting of the upper on one side of the shoe, the toe portion is stapled in the usual way of the Drey patent, and the. other side of the shoe upper is lasted in accordance with the procedure of this invention.

From the foregoing description it will be understood that the novel procedure employed by me involves the side lasting of the upper by pulling over'the edge of said upper at two points located at the opposite sides of the point of insertion of the staple, and further that this pulling over of the upper in the side lasting thereof 1012 takes place simultaneously with the stapling operation.

By my invention I am enabled to omit hand operation of side lasting the manual labor performed by the workmen hereto- 165 fore referred to as side lasters, and, furthermore, the labor of driving the lasting tacks prior .to stapling, and of pulling out the lasting tacks subsequent to stapling the .upper are wholly omitted, thereby simplifying the procedure and effecting substantial economy in the operation of lasting and making the shoes. 1

Having thus fully described the invention, what I claim as new, and desire to secure by Letters Patent is:

1. In the art of making shoes, the improvement which consists in providing an insole with an upstanding.lip,-and simultaneously side lasting the upper and stapling the upper to said upstanding lip'of the insole, said upper being pulled relative to the last and the insole at points positioned y at opposlte sides of the point of insertion 1 of the staple.

' 2. The process herein described of making shoes, which consists in providing an insole with an upstanding rib, attaching said insole to a last, drawing the upper around the last, and stapling the edge portion of portion ofthe insole 75 shoes,

messes the upper to the upstanding rib of the insole and simultaneously therewith side lasting the upper by drawing it at two points positioned at the respective sides of insertion of the staple fastener.

3. The process herein described of making which consists in providing an insole with an upstanding rib, attaching said insole to a last, pulling over an upper relative to the last, and directly thereafter stapling the upper to the upstanding rib of the insole and simultaneously With said stapling operation side lasting the upper by pulling it over the insole and lastat points positioned on opposite s1 les of the point of insertion of the staple fastener.

et. The process herein ing shoes, which consists in providing an insole with an upstanding rib, attaching said Copies of this patent may be obtained for described of ma insole to. a last, pulling over an upper relative to the last, and directly thereafter stapling the upper to the upstanding rib of the insole and simultaneously With said stapling operation side lasting the-upper by pulling the free edges [of said upper at two points over the last and the insole, the points of strain being at opposite sides of the insertion of the staple fastener and the direction of the pull being against and over the edge of the insole.

In testimony whereof 1 have signed my name to this specification in the presence of two subscribing Witnesses.
