WILLIAM J.'YOUNG, OF LYNN, MASSACHUSETTS, ASSIGNOR TO W. J. YOUNG MACHINERY COMPANY, OF LYNN, MASSACHUSETTS, A

CORPORATION OF MASSACHUSETTS.

MACHINE FOR FORMING OUTTURNED SHOE-UPPER-S.

To all whom it may concern:

.Be it known that I, WVILLIAM J. YOUNG, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new anduseful Improvements in Machines for Forming Outturned Shoe-Uppers, of which the following is a specification.

This invention relates to a machine for molding shoe uppers, especially the heel parts of the'same, with the edge which is attached to the boot or shoe sole turned outwardly. Heretofore in making shoes in which the sole is attached to the upper by outward flanges on the upper, or outturned uppers, it has been the'practioe to turn-out the edges of the upper, by which the attaoh- .ing flanges are formed, by hand.

Accordingly my invention has for its objecttoprovide a' machine capable of performing the work hitherto done by hand, that "is, of forming boot and. shoe uppers with outwardly turned flanges'for attachmentto the sole of a boot or shoe.

The invention consists in the instrumen- ,talities constructed, arranged and operating Fig. '2 represents a perspective view of a shoe upper having an outwardly turned edge at the rear or counter portion thereof, the same being the product of this machine. Fig. 3 represents a longitudinal section of themachine, showing the parts in the position they occupy'when a counter is operated upon. Fig. 4 representsa cross-section of the counter mold and flange former,taken on lineH of Fig. 3. Fig. 5 represents a planview of the same. Fig-.6 represents a plan'view of the female mold and the parts by which it is operated, the machinerbeing represented as havingthe edge turnerand presser andits guides removed and the male mold or last broken away. Fig.1? represents a plan view showing the relative positions of the moldsythe counter blank, and the presser at the beginning of the operationof turning out the edge of the'counter. The" same reference characters indicate the same parts in all the figures.

Referring to the drawings, theiframe. f

the machine is represented by 1, upon which are supported inclined bars 2 connected at the front of the machine by a cross-piece 3. Supported by the cross-piece 3 between the members 2 is a male mold or last 4: which is fastened to a bolt 5 passing through ari apr erture 6 in the cross-piece 3, and is held against the latter by a spring 7 acting against the head 8 of the bolt. The female mold or mold proper consists of two

parts

9 and 10 secured to levers 11 and 12 which are plvoted upon a cross head 13. The

parts

9 and 10 of the mold are recessed at 14 and 15 in their adjacent inner sides, these recesses together forming a mold which, when the

members

9 and 10 are pressed toward each other, is of the shape of the counter or rear portion of a-shoe upper. The last or male mold 4 is shaped at its end and sides so as to correspond with the contour of the recesses 14 15 to cooperate with the female mold in giving the shape to the upper. The sldes ofthe last are recessed, as shown b dotted lines at 16 and 17, so that the sides of the upper at the shank of the shoe may be brought inward nearer together than they are at the heel portion.

-The'n1ale mold or last is normallv stationary and abuts againstthe cross-piece 3 of the frame. The female mold is brought down to the last and its members moved inward to bend the heel portion of the upper around the last, by means of stiff spring fingers l9 and 20 which project beyond the ends of the levers 11 and 12 and are brought against

inclined wedge members

21 and 22. The reciprocating movement necessary to carry the mold from the position shown in Fig. 6 to that in Figs. 3 and is given by a cam 23 acting through a roll 24- upon a rod 25, which latter is connected to theknuckle 26 of'a toggle joint 27 28. The abutment for the toggleis a plunger 29 which thrusts against a spring 30 held by a bolt 31 and adjusting nut 32 which bears upper surfaces of the molds, and removed therefrom by a distance equal to the-thickness of the edge of the counter.

The presser or bender 37 is provided with ribs 40at its opposite sides which are contained in grooves in a frame'4l (see Fig. 4), which frame is mounted ina carriage 42 and carriesalso an elastic pad or cushion 43 and a backing plate 44 which is pressed down upon the pad with more or less force by adjusting screws 45 so as to regulate the force with which the presser is caused to bear against the edges of the blank after it has bent the same over. The carriage 42 has flanges46 which run in the guides 38 39 and are held therein by retaining strips 47. The

side members 48 of the carriage extend to a cross head 49 to which is connected a link 50, thelatter being pivoted to a bell-crank lever 51 having an arm 52 to which is pivoted-a connecting rod 53 having a rolla54 which enters the groove of a positive cam 55.

As shown in Figs. 3, 5 and 6, the flange presser 37' has. one end 56 formed as a rounded blunt end, and when not in operation, the presser is normally held in front of the molds with its blunt end extending in the samedirection as the last 4 and pointing toward the curved rear end of the latter and the bottom of the recess 14 15 in the female mold. It is caused by its operating mechanism to reciprocate in the same direction as" the cross head 13 carrying themembers 9 10 of the mold is moved. Both the cams 55 and 23 are mounted upon the same shaft 57, which is driven from a counter shaft 58 through a pinion 59 and gear 60. These cams bear such an angular relation to each other that when the machine is at rest, the members of the mold are separated from one another and the presser is at its greatest distance in-front of the mold, leaving the latter uncovered so as to receive an upper between them. After insertion of an upper, this being accomplished through the space between the sides 48 and the parts 4249 of the'carriage, the machine is set into motion. The first part of the operation of the machine is effected by the cam 23 and causes the members of the mold to be closed about the last, shaping'the counter, portion of the upper and holding it in position to be operated on by the presser. A long dwell of the cam 23, extending nearly through 180, as shown by dotted lines in Fig. 1, holds the molds while the presser is carried over them. Inits movement, the presser advances toward the open end of the socket in the female mold, its wedge-shaped end- 5.6

The means for bending this it firmly againstthe same entering between the ends of thefU -s'haped blank. As it progresses toward the rear end of the blank, it forces the edge thereof which projects from the molds" outward and lays it against the plane surface of the female mold: The elastic pad 43 allows the 'presser to yield as it passes over the edge of the upper, and at the same timepresses so as to give a permanent set to the flange 36, which is made by so laying over this edge.- The presser' remains in the positionshown in Fig.; 3, holding the overturned edge while the dwell from a-to Z of the cam 55. travels past the roll 54. .The presser is then retracted,.- the femalemold withdrawn, and the upper is releasedso that-it -falls through an: opening 61 between. the members2' of the frame. \Vhenthemembers 9 10 of the mold are withdrawn, they are separated from one another .by a pin 62 which is pressed against them between the pivots of the levers 1-1 and 12 by a spring 63.
