SPRING FOR SHOE FORMS Louis W. Reinhardt, Brockton, Mass, assignor to George E. Belcher Company, Stoughton, Mass, a corporation of Massachusetts Application July 25, 1935, Serial No. 32,986 5 Claims. (C1. 12——128.4) My present invention relates to improvements in hollow shoe forms. cated at I in Fig. 1 as applied to a hollow shoe _ form 2 described in detail in my co-pending ap The widespread demand for a less expensive shoe form has resulted in many attempts to 5 provide such a form that will satisfactorily meet all the requirements as to appearance’ and. strength. In my co-pending application, Serial No. 1,271 ?led January 11, 1935, I have shown a plication, Serial No. 1,271. The form 2 is shaped to provide the desired internal support for the . novel hol1ow shoe form that provides the essen resulting from the disposal of slackage developed during the molding of the form 2. The strength 10‘ tial ?rm, well ?tted internal support for the shoe that meets that demand. The hollow shoe form shown in my co-pend ing application, Serial No. 1,271, is molded from a textile blank such as presized buckram and is 1-3 characterized by a substantial sole ?ange having reenforcing plaits in the forward portion de veloped in molding operations, which plaits are disposed in preservation of the line of contact of adjacent ?ange surfaces with the inner sole. 20 A spring bridges the ?ange and ensures the de sired lateral resiliency. While such a form may be made of light stock, it is of great strength and its resiliency permits its insertion into the toe cavity to effect a con 25 cealed- reenforcement. Such a form, however, emphasizes the problem of removing these forms | because of the tightness of the ?t and the char acter of the stock from which they are made. This problem is obviously present to some extent 30 with all acceptable forms, but varies with the effectiveness of the support rendered and the type of shoe in which it is to be used. Of the many types and styles of shoes, women’s shoes not having a tongue well illustrate the dif?culty 35 of dislodging a concealed tight ?tting form. I have solved this problem by providing a novel spring’, which, while exerting the necessary lat eral pressure to ensure the tight ?tted support for the toe portion of a shoe is so formed that 40 it may be compressed to free the form when properly contacted by an extractor. 1 In the accompanying drawing I have illus trated my novel spring as applied to a form made in accordance with the invention disclosed in my 45 co-pending application, Serial No. 1,271. In the drawing: Fig. 1 is a bottom view of such a form with my novel spring attached. Fig. 2 is a plan view of a shoe supported by 50 such a form. Fig. 3 is a vertical section through such a shoe and hollow form, and Fig. 4 represents a suitable compressive ex tractor. 55 I have shown my novel spring generally indi toe portion 3 of a woman’s shoe. Such a form is molded from a presized textile blank and includes an integral sole flange 4 hav ing upturned ends 5. I have indicated at 6 plaits of the form 2 is such that it may be made of light stock giving the form 2 an inherent re siliency which with the addition of a spring renders the form 2 extremely well ?tting. While a form thus made is acceptable as far as strength and appearance are concerned, its withdrawal from a toe cavity is di?icult as will be appreciated from Fig. 3. For that reason, the wire spring I includes a U-shaped head 1. and diverging end portions 8 terminating in inturned loops 9 which permit the ends of the spring to be securely anchored as by eyelets [0 to the flange 4 at substantially the widest part of the form 2. The head ‘I is preferably upturned as may be seen in Fig. 3 and it extends forwardly to a point near the front of the form 2. The extractor H includes an upwardly bent portion l2 and a handle indicated as at IS. The portion l2 has a rounded end which permits the extractor to be used in lodging the form 2 in the toe cavity 3. Near the rounded end of the extractor H is an aperture M of a size suilicient to permit its free passage over the head ‘I to permit the com pressive contact of the diverging portions 8 of the spring I as the extractor H is withdrawn. When it is desired to remove a form from a shoe, the extractor H is inserted therein sub stantially as far as possible. Because of the rounded end of the extractor II and the shape of the form, the aperture I4 is properly aligned with the head ‘I of the spring I. The aperture M passes over the upturned head ‘I as the ex~ tractor II is withdrawn and is guided to con tact and compress the diverging portions 8 to draw the ?ange 4 inwardly and free the form 2 as indicated in Fig. 2 so that it may be removed with the extractor II. I am thus able to provide a spring that may be used with any conformablesupport and that, while serving to ensure the well ?tted support, is adapted to be used to free such a form so that it may be removed very easily. In accordance with my invention, I am able to provide a hollow shoe form improved as to 2 2,074,273 appearance and as to the support rendered that fully satis?es all requirements. What I therefore claim and desire to secure by Letters Patent is: l. A hollow shoe form adapted to render a well ?tted internal support for the toe cavity of a shoe, a spring bridging said form and being adapted to ensure said support when said form is lodged in said toe cavity, said spring including 10 a U-shaped head lying near the front of said form and diverging'ends anchored to opposite portions of said form, said diverging ends being adapted to be compressed upon retractive en gagement by an extractor and said head being 15 upturned to facilitate said engagement whereby 3. In a hollow shoe form adapted to furnish support for the toe cavity of a shoe, a spring bridging said form and tightly forcing said form against the walls of said cavity, said spring in cluding inturned arms anchored at their ends to opposite sides of said form and united ad~ jacent the toe part of said form by an elon gated portion adapted to center and to guide an extractor over said arms to position to re tractively compress the same to permit removal 10 of said form from a shoe. 4. In a hollow shoe form adapted to furnish support for the toe cavity of a shoe, a spring bridging said form and tightly forcing said form against the walls of said cavity, said spring in 15 said form may be readily removed. 2. A shoe form comprising an integral upper and sole ?ange molded from a cementitiously cluding inturned arms anchored at their ends to opposite sides of said form and united by a presized textile blank, said sole ?ange being of and to guide an extractor over said arms to po sition to retractively compress the same to per 20 mit removal of said form from a shoe. 5. In a hollow shoe form adapted to furnish 20 substantial width and including in its front por tions reinforcing folds constituting residual slackage of the ?ange stock developed in the molding of said form, said folds being disposed to permit the contact plane of said ?ange and 25 the inner sole surfaces to be determined by ad jacent ?ange surfaces, a transverse bow shaped spring anchored to said ?ange to cooperate with said form in establishing a well ?tted internal support for a shoe, the bow of said spring be 30 ing forwardly disposed and shaped to be com pressed by retractive contact on each side of the center of said spring to permit said form to bev readily removed. r U-shaped elongated portion adapted to center support for the toe cavity of a shoe, a spring bridging said form and tightly forcing said form against the walls of said cavity, said spring 25 including inturned arms anchored at their ends to opposite sides of said form and united by an upturned elongated portion adapted to center and to guide an extractor over said arms to position to retractively compress the same to 30 permit removal of said form from a shoe.
