MILLER & SONS, INCORPORATED, A CORPORATION OF NEW YORK Application filed June 13,

This invention relates to the shoe art and deals more specifically with a turned shoe and the process of making the' same.

In accordance with the prior art practice of making turned shoes, the complete upper is assembled as a unit and sewed to the outsole, the upper being turned inside out. Following this operation, the last is withdrawn and the shoe is turned rightside out.

In manufacturing ladies shoes, slippers and sandals of the open shank type, the trouble and expense of following the prior art practice has made it desirable to develop a new method of making these last mentioned products,which method still retains the desirable features of the turned process.

Briefly, the present invention is realized by preparing, on separate lasts, the upper in two separate sections, a forward section and a rear section, and later joiningthe two sections together to form the finished shoe.

The manner in which the present invention is carried out will be more fully understood from the following description taken in'connection with the accompanying drawings, in which:

Fig. 1 is an exploded view of a sandal constructed in accordance with the principles of this invention;

Fig. 2 is a similar/view of a modified form of the invention; a

Fig. 3 is a perspective view of a further modification of the invention; and

Figs. 4 to 8 inclusive are detail views. Referring in detail to the drawings, the sandal is seen to comprise a forward section 10 and rear section 11, the two sections being adapted .to be fitted together to form the complete shoe.

Referring more particularly to Fig. 4, the

method of producing the rear section 11 will be described in detail. A shank piece 12, such as is commonly used in the turn process, having a steel shank stiffener 13, is provided with a binding tape 14, which is cemented around the marginal edge of the piece 12 in order to present at the edges the appearance of a finished product. It will be understood that the binding 14 may be chosen of any suitable material to correspond with the fin- METHOD OF MAKING SHOES Fiftttlitfi ish of the particular shoe or sandal. For example, if the upper of the shoe is goldkid, the binding 14 would also be of gold color and preferably of the same upper leather. Alternatively, a different color maybe used to give a desired ornamental effect. After the binding 14 and shank stiffener 13 have been positioned on the shank piece 12, the latter is tacked onto a last and the counter portion 15 of the sandal is tacked in place. The counter portion 15 comprises the side straps 16 and 17, which are tacked to the bottom surface of the shank piece 12 by tacks 18; the rear strap 19; and the counter strap 20, which terminates in the ankle strap 21 in the manner shown. In accordance with the preferred embodiment of this invention the counter portion is formed by sewing the 1931. Serial N0. 544,118.

separate straps together, but it is also feasiportion over on to the heel surface of the shank member and. tacks 19?) (Fig. 4) are driven through this edge into the heel of the shank member, whereby to unite the two and at the same time furnish a support for the counter portion. Any suitable fastening means (not shown) may be used to join the ends of the ankle strap together, either in front of the ankle or at the side thereof.

Having prepared the counter portion of the sandal or shoe, the forward portion, which includes the vamp and toe of the sandal, is now prepared as follows a Referring in detail to Figs. 1, 5 and 7, the outsole 30 is first tacked onto a last with the tread surface of the sole in contact with the bottom of the last and the channeled surface of the sole outward. The forward portion, which comprises the vamp and toe, is lasted inside out and in this position is stitched to the lip 31 of theoutsole 30. This operation isin accordance with the prior art practice of assembling turned shoes. Next, the surface of the 'outsole, including the lip 31, is trimmed to eliminate unevenness and the extra material resulting from the stitching operation. The last is then withdrawn an the forward portion, the outsole still being in temper, is turned rightside out. This gives a step product as shown in Fig. 7. The forward portion, it will be seen, comprises the toe portion 32 and the vamp straps 33 and 34. Additional binding strips 35 are sewed.

to the outsole as shown more specifically in- Figs. 5 and 7 so that when the forward portion is turned and the shoe assembled the marginal edge portion of the top surface of the outsole is covered by these binder strips at the cut-out portions 36 (Fig. 1). It will be understood that the binder strips 35 may be of any suitable material to harmonize with the finished product in the same Way as was described in connection with the binding 14. The toe-portion 32 has a rearwardly extending strap 37 to which the side straps 33 and 34 are Joined.

After the forward portion is turned as above described, the upper rear surface of the outsole from a point substantially at the ball line of the foot rearwardly to the heel is roughened and a celluloid cement applied thereto. Similarly, the bottom surface of the shank piece 12 is roughened and a corresponding coating of celluloid cement is.

applied thereto. The next operation involves the assembly ofthe two portions together, and before this operation is performed, a solvent is applied to the cemented portions to render the same tacky, the cement in the meantime having dried. Following this operation, the rear portion, which is still mounted on thelast, is fittedtogether with the forward ortion, which is not on a last, the last of tlie rear portion being used to fit into the forward portion, whereby the two are brought together on a single last. The.

thus assembled product is then placed in a machine having pneumatic pads and a rotatable table carrying these pads, in such a way that when the last is clamped in place the table rotates to. a position where air is admittedinto the interior of the pads, thus applying pressure to the sole oftheishoe.

The table rotates until an unloadingposition where the air is released and the shoe re-' moved. It will be understood that the time interval during which the assembled shoe is kept under pressure may be regulated by the speed of rotation of the table or by some other obvious means. Obviously, .any. type of machine having pneumatic pads may be used instead of the one having the rotatable table. There are many such machines commercially available and further detailed des'cription is therefore unnecessary. Upon removing the assembled shoe from the press, i K

known methods now commonly used. Y

- In accordance with a modification of the present invention, as illustrated more particularly in Figs. 2 and 6, the rear or counter portion is assembled to include, in addition to the side .straps 16 and rear strap 19, one of the straps 234 which is attached to the shank piece 12, usually by tacks, in the same position that the strap 234 would take, were the shoe constructed in accordance with the modification of the invention illustrated in Fig. 1. The forward portion of this form of the invention is prepared inthe same way as described in connection with Fig. 1, with the' exception that this forward portion now'only includes the toe portion 32 and the sidev strap 33. The remaining steps of the process of preparing this form ofthe invention are the same as those already described.

Referring now in detail to Fig. 3, the present invention is shown applied to an ordinary slipper of the open shank type in which a unitary vamp 300 is assembled on the outersole 30 in accordance with the standard practice of a turned shoe process. Similarly, therear. or counter'portion 301 is assembled with the shank piece 12 in a manner similar to that described in connection with Fig. 4, but differing therefrom in thatthe ture as distinguished from the strap members shown inFig. 4. In this form of the invention the usual counter may be used and it is held in place on the shank member 12- by tacks passing through the edge which folds over onto the heel surface of the piece 12. Following the preparation of these separate portions, the two are assembled in accordance with the method described above;

Many changes in the foregoing specific embodiments of this invention will readily suggest themselves to those skilled in the art without departing from the spirit of this invention, whose scope is not to be limited ortion 301 is of a unitary strucincluding an outsoleand vamp including the exposed upper material on a; second last, withdrawing the second last, turning said forward portion, and joining said'first men-v :tioned portions and said forward portion I together.
