SPRING-HEEL role sirens. l

Application filed January 19, 1915. Serial No. 3,039.

T 0 all whom it m (11 concern.

Be it known that I, THOMAS A. a citizen of the United States, and of Bridgeport, in the county of Fairfisld and State of Connecticut, have invented certain new and useful Improvements in HUSSEY,

Spring-Heels for Shoes, of which the following is a specification.

My invention relates to certain new and useful improvements in spring heels for shoes and refers particularly to what may be termed an attachable form of spring heel.

The purpose of the invention is'to provide a spring which may be secured to the inside of the heel portion of a shoe in a Way to form a rigidly attached spring heel portion, whereby the jar or shock caused by walking on hard surfaces will be lessened; to design the spring in a simple and durable manner and whereby the same may be rigidly secured in position so as to further insure its retaining its spring tendencies.

With these and other objects in view the invention resides and consists in the construction and novel combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended, it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claim may be resorted to wi thout departure from the spirit or sacrificlng any of the advantages of the invention.

Similarcharacters of reference denotelike or'corresponding parts throughout the several figures of the accompanying drawings forming a part of this specification and upon which- I Figure 1 shows a side elevation of a shoe the heel portion of which is broken away, illustrating a longitudinal vertical section and showing my spring plate attached thereto. Fig. 2 is a bottom plan view of the shoe and further illustrates the means for attaching the spring heel plate in position. Fig. 3 is-a detached view of the spring heel plate shown in Fig. 1. Fig. 4 is a detached plan view of the outside stiffening plate employed for backing up the underside; of the instep of the sole of a shoe and Fig. 5 shows a detached side view of one of the screws and nuts employed for clamping the parts together.

Referring in detail to the characters of reference marked upon the drawings 6 rep- Specification of Letters lPatent.

indicates the arch of the sole, 8 the heel and 9 the inside of the heel portion of a shoe. The spring member proper of my device as will be noted consists of a single piece of sheet spring steel indicated by'lO and shown clearly in Fig. 3. This piece of metal is shaped to conform .to the inside of a shoe heel .and includes a slight central concaved portion. "The uppersurface may also be provided with a covering of sheep skin or other-suitable material 11 to provide a suitable wearing surface. The shank portion of the spring is provided with screw holes 12 by means of which the spring is secured in positionwithin the shoe. As will be noted the shape of the spring is such that when attached to the inside of the arch of the sole it, will benormally disposed upward of]? from the inside 'of'the' heel-portion of the shoe. The spring is-made sufficiently stiff to require the Weight of a man upon it to bring it down against theshoe. The screws 13 which'extend through the holes in the arch of the sole of thelshoe also pass through a rubberj lwasher '14 "that lies between the outside ofthe archo fthe sole and the outside stifi'ening plate 15, and serves to not but also to cover a considerable part of the underside of the arch of the solo in a way to stifi'en and hold the same in a more rigid position. The nuts 16 which are placed upon the threaded ends of the screws are turned up tightly against the said stiffening plate 15 in a way to firmly clamp the spring plate as well as the stiffening plate against the arch of the sole of the shoe thus insuring the said spring being disposed in a normally raised position as indicated in Fig. 1. A construction of this sort with the intervening rubber washer is perfectly tight and will not permit any water to enter through the screw holes. As will be noted the device may readily be attached to any shoe by simply putting a conple of holes through the sole as required for the attachment of the screws in the manner indicated.

The outside stiffening plate is a necessary and essential "featurelof the device since it stiffens the sole and insures the spring standing out in its proper position and also insures the screw retaining a firm and rigid position which could not be expected if it did not pass all the way through the sole and if it were not backed up by a stiff metal plate as indicated. Practical demonstrations have proven that a construction of this sort will insure the spring retaining its yieldable position for a considerable length of time.

Having thus described my invention what I claim and desire to secure by Letters Patent is:

In a spring heel for shoes, the combination with a shoe the arch portion of the sole of which is provided with suitable holes therethrough, of a spring plate shaped to conform to the shape of the inside of the sole of a shoe and having holes to register with the holes in the sole, screw bolts passing Copies of this patent may be obtained for through the said holes of the plate and the sole, a rubber washer upon the outer threaded ends of the screws, a metal stiffening plate also having holes to accommodate the screws and seated against the underside of the sole, and nuts attached to the screws and against the stiffening plate to retain the spring in a yieldable position.

Signed at Bridgeport in the county of Fairfield and State of Connecticut this 15th day of January, A. D. 1915.

THOMAS A. HUSSEY.
