MACHINE FOR FORMING HEEL-LINING INSERTS FOR BOOTS ANIDISHOES.

\ To all whom t may concern i Be it known that we, EDWIN Il. ELiAsoN and Geenen H. ZIEGLER, citizens of the United States, residing 1n Philadelphla, Pennsylvania, have invented certain Improvenients in `Machines for Forming Heeli Lining `Inserts for Boots and Shoes, of which the following is afspeeification.

The object of this invention is to construct a machine for rapidly and accurately forminga heel lininginsert adapted for use in boots and shoes. This insert is to be used whenthe lining at the heel is worn and by inserting this lining in a shoe in which the original lining is worn, it `takes the place of the original lining and prevents the stretched; Fig. 7, is a perspective View of .y

the die and arms; Fig.` 8, is a perspective view of the U-shaped plate; Figs. 9,10 and l1, are diagram views illustrating different steps of theprocess; Fig. l2, is a sectional view on the line 12-12 when the parts are in the position illustrated `in Fig. l1; Figs. 13, 14 and 15 are views showing the different steps in the process;Fig..16, is a perspective view of the metallic stifleners; Fig. `17, is a perspective view of` theheel insert with the metallic stiffenerin place, and Figs. 18 `and 19 are perspective views of the finished heel insert. l

^ A is the base of the machine supported on suitable legsja and mounted on this base is a form B made hollow as shown. Within the form is a suitable gas burner b2 connected to a gas supply pipe b3, for heating the form to the proper degree. The upper surface of theform is rounded, as `illustrated, to conform to the shape of the back of the shoe, while the front is flat so as to receive the` sole piece to which the body of the heelyinsert is secured. On the front is a projection having a beveled groove b to Specification of Letters Patent.

` of the solepiece av and a pin bt projects from the form on which the sole piece is forced. i The solepiece is thus held vertically against the form.`

receive the end Projecting from the base `A. aretwo posts C, having bearings c for a; transverse shaft on which is mountedan arm `C2 and this shaft 1s turnedby means of a handle c and is preferably counter-balanced by a weighted arm c2.

Adapted to` slideyertically on the posts C-C is a cross head D. This cross head is connected to the arm by longitudinally adjustable links D. In the present instance,

each linle consists; of two `threaded `sections and a turn buckle connects the sections,:so

that on turning the turn bucklethe cross head can beladjusted toward or` from the form B. Secured to the cross head are bear ings Ze-(Z for vertical rods e-e attached to the die E, which conforms to the shapeiof the upper surface of the form B.` Springs c are mounted on the `rods e between the die and the bearing (l and tend to press the die toward the ferm.` The downward movement ofthe die is` limitcdby `the nutse? on` the ends of the rods coming incontact withthe bearings.

Adaptedto slide laterally under the side of the cross head Dfarc two bearings F-F.`

l l hach of these bearings 1s slotted for the re-` ception of a pin andare normally held away from the center of the head by springs i j. Pivotally mounted on each sliding bearing Fare arms F', which are shaped to conform to the sides of the `form B andare beveled at the end to form wedges so that they will` pass between the form and the press rolls ge-,r/ `which are, in the present i instance, mounted on plungers G-G adapted to bearings G. Back of each plunger G is a coiled spring g', which tends to force them toward the form B.` The plungers Gr have extensions which pass through caps g2 and are provided with nuts g3. By adjusting thecaps onpthe bearings G', the inner position of the rolls g can be regulated according to the size of the form used, as it willfbe understoodthat there must be `a l and an adjustable cap h2 and on the end of the stem of the plunger, which extends through the cap, are adjusting nuts h3.

' Adapted to slide on standards l is a cross head 1, which is connected by rods Ji to a bar lf2 under the base A and this bar is in turn connected by a link J to a lever J pivoted to a depending bearing A at a. The lever is in turn connected by a link J 2 to a foot lever J3, also pivoted to the bearing A. On operating the foot lever the cross head I will be drawn down. Springs z" mounted on the rods l and between the cross head and the base A, tend to force the cross head up as soon as the foot lever is released.

Pivoted at a to the cross head in line with the form B is a plate N. @n this plate N is a U-shaped plate n which turns the projecting flange of the blank of the heel insert against the sole piece This U-shaped plate is beveled so that when it is forced down it crimps the ange of the blank and as it passes the rolls 71, it is forced toward the form and in turn presses the inturned flange against the cemented surface of the sole piece.

In order to push the rolls g-g back from the form G, we provide two levers M, pivoted at m to bearings on the base A, and these levers are connected to the ends of the plungers G and in the lower ends of the levers are inclined slots m into which eX- tend pins ,fo-p of a two-armed lever P carried by a shaft P mounted inbearings secured on the under side of the base .A The operating handle P2 is attached to the shaft within easy reach of the operator so that on turning the shaft the plungers G G and the rolls move away from the form.

In order to move the roll /L and its plunger H away from the form, we pro vide a cam m2 on one of the arms M which acts upon an arm H3 attached to the plunger H so that on operating the lever M the plunger will be retracted against the pressure of its spring.

s-s are platforms mounted on the bearings G in the present instance and shaped to receive the ends of the body blank which forms the back of the side portions of the heel insert, and hold it central over the form.

This machine does not finish the entire heel insert, but shapes it and places the parts in the proper position so that they can be readily finished by hand or upon another machine. n

The operation of the machine is as follows :-The blank m forming the body of the heel insert is subjected to moisture to make it pliable and to allow it to be stretched over the form. We prefer to place the blank in a steam boX at one side of the machine, but. any other suitable moistening means may be employed. The body blank is then placed on the form B, the edges resting on the platforms s-s and above the rolls g. The sole piece fr is cemented on one face and placed in position at the end of the form. The shaft C is then turned through the medium of the handle c and the head D is moved toward the form B. The arms F', as they move downward, press the side portions of the blank m against the rollers g, g, and stretch the blank over the form B.

The overhanging edges of the blank an are tucked in against the cemented surface of the heel piece by the U-shaped plate as it is drawn down by the treadle J s, between the roll L and the form B, forcing the inturned edges of the blank a; against the blank and holding it there while the cement sets, after which the parts are released and the formed heel insert is removed from the machine. The back section as is stitched to the heel piece The metallic stiffeners X? Fig. 16, are then placed in the pockets c3 formed in the sections af: and the projecting ends of the material forming the pockets are turned onto the heel piece, after which the fabric base section is cemented to the bottom of the heel insert, Fig. `18, making the complete article, as in Fig. 19.
