CGMBINED ASSEMBLING AND LASTING ll'LACHINE.

Original application filed January 18, 1921, Serial No. 438,132. Divided and this application filed Neveinh-er 17, 1921. Serial No. 515,830.

To all "whom 722.14g ammo 1m Be it. known that I, thinness l5. Looarv. resident of Palmyra, in the county of Lebanon and titate of Pennsylvania, a citizen of the United States, have invented certain new and useful Improvements in Combined Assembling and Lasting" lllachines, of wlrch the following is a SPGOlDCZLlZlOH.

This application is a division of an application filed by me January 18th, 1921, Serial No. 438,132, the present invention relating especially to a mold employed in the combined assembling and lasting a shoe upper having; an intnrned flange with a shoe sole. H

The invention has reference to shoe-making machinery in which anupper is suspended in inverted position within a mold, a last is forced down into the inverted mold, pressure applied so thatthe upper is shaped to the last, an insole coated with an adhesive supported on the last, an outer sole applied to the insole and the upper, and pressure then applied to the outer sole while the adhesive sets. I p I i I The invention is illustrated in the accompanying drawings and will be hereinafter fully set forth.

In the drawings,

Figure 1 is a plan View of the mold.

Figure 2 is a section on the line 2-2 ot Figure 1.

Figure 3 is a. section on the line 33 ol l igure 1.

The mold comprises a body adapted to reston the table between the brackets 19 and 22 and haviru; a central opening 51, in which the upper is suspended. The opening 51 corresponds in shape to the shoe and the l at is arranged in the opening; in the same manner previously described. Slidably mounted on the top of the mold are wipers 52 which operate substantially at a right angle to the opening 51 and are adapted to fold the edge; of the upperover onto the insole, it being understood that an insole is placed on the last, and coated with cement before the last has been forced into positon within the upper. To operate the wipers, l

onto the same.

pivot-ally mount an angle lever 53 on the mold adjacent each side wiper and one arm at the lever is pivoted to the :ufljacent wiper uhile theother arm of the lever extends toward the adjacent side of the mold. The outwardly projecting arms of all the levers are pivoted to a link or push-bar 5d extendto the front of the mold and equ'pped with a handle 55 oi any preferred or convenient form. One of the push bars is-provided adjacent its front end with a lateral arm. 56 extending toward the central plane of the mold and the tree end of this lateral arm is connectedby link 57 with the toe wiper 52. At the opposite side of the mold, the push bar is pivoted at its rear end to a straight lever 58 which is fnlcrumed between its ends upon the mold and has its inner end pivotally connected with the heel wiper 52. Grip 'rer fingers 59 are provided upon the mold to stretch the upper andsuspend it in the mold. I After the insole has been placed in position, as above stated, the gripper fingersare released and the push bars 5% shoved rearwardly thereby actuating the wipers so that they will move inwardly over the edge of the insole and told the edge of the upper The outersole, coatedv with cement on its under side, is then placed over the insole and the inturned flange of the upper, after which the presser block is forced down upon the outer sole to hold the parts in contact until the cement sets, after which the shoe removed and'trimmed.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I have provided a strong, compact, simple, and easily operated machine by which shoes, particularly those of the stitchdown type, may be rapidly lasted and the usual pulling-over machine dispensed with.

It is to be understood that I'do not limit myself to the specific details herein described and shown as various minor changes may be 'made therein within the scope of? the appended claims.

Having thus fully described my invention what I claim as new and desine to secure by Letters Patent of the Unlted States 1s 1. The comhmetlon of a mold, gwlppmg fingers mounted thereon, Wipers sliclably mounted on the mold and means for moving the Wipers toward and from the center of the molcl.

The combination of amold, means for CHARLES B. LOGAN.
