JOHN ZOOBOAVCII, OF BROOKLYN, NEW YORK SPRING A'r'rAcHMEN'r FOR snons.

I To all whom it may concern:

Be .it known that I, JOHN Zoo oAvon, a citizen of the Un1ted'St-ates,.residing at Brooklyn; in the county of Kings and State of New York, have invented new and'useful- Improvements in Spring Attachments for Shoes, of which the following is a specificapermanent or attached member.

a perspective vlew of the movable member tron.

This invention relates to shoe springs or devices to be placed beneath the sole of a boot or shoe to produce a resilient effect in lifting the shoe as it leaves the ground, as will be more fully described in the following specification, set forth in the claims and illustrated in the drawings, where: 4

Figure 1 is a side elevation of the lower part of a shoe showing my improved spring applied thereto. Fig. 2 is a perspective view 0 the movable member of the device from its under side. Fig. 3 is a similar/view of the Fig. 4 is from its upper side. Fig. 5 is a cross sectional view through the device, taken on the lane indicated by the line 55, Fig.1. ig. 6

illustrates a modified construction of thedeof pressure is exerte vice. Fig. 7 is a perspective detail view illustrating the manner of securing the spring u on the base plate.

The 0 'ect of the invention is to roduce a cushione effect upon the foot of the wearer in walking and it is to be placed under the sole of the shoe between the heel and the ball of the foot and is adapted to normally extend below same so that when the shoe comes in contact with the round a certain amount a on the device. he base iece 10 has at each corner a per foration 1 1 or the passage of screws or rivets which are designed to secureit to thesole of the shoe and at one end is a socket 12 which affords one of the means by which the movable member is secured tothe base piece. From the r latter, projections or brackets 13 are stamped and stand at right angles to the plate, and between these projections are secured'the springs 14 whose free ends extend downward.

hese springs may be sheet steel as shown and provided with a struck-up lug ortongue 14' at one comer thereof to be inserted through a slot or aperture 15 in the base plate and clenched upon the opposite side of the latter, thereby securing thespring in 0- sition. S rings made of wire, and secure in any suita le manner may be used, if pre ferred.

Specification of Letters Patent. Application filed. February a, 1908. Serial No. 414,971,

Patented Sept. 15,1908.

The movable member consists of a curved plate1-5 havingsid-e pieces 16 turned at" right angles to same and which are adapted to fitand work on the outside of the pro ections13 of the plate 10 to steady the member and prevent lateral movement. The forward end'of the plate 15 is formed into a tongue 17 which enters the socket 12 and the plate may otherwise be held in connection with the base piece by means of a screwlS passing through a slot 19 in the rear tongue 20. The plate 15 also has a bail 21 with a perforation 22 to receive a screw 23 carrying the nut- 24 which limits the distance which the plate 15 stands from the base piece, and this distance may be limited by the nut and screw. 18 when desired. The lower face of the plate 15 is covered with one or more strips 25 of leather or rubber as a bearing surface and to also render the device noiseless. This device applied to the bottom of a shoe greatly aids the wearer in walking as it gives a sprin movement to the effort to raise the foot an consequently reduces the labor involved in walking. The compression of the spring simply results from the force of the from the shock occasioned by walking and particularly on hard pavements.

The invention is especially adapted for use by people threatened with spinal or nervpus troubles as it relieves the spine from the Jplt and shock which it might otherwise sustain.

What I claim as new and desire to secure by Letters Patent is:

1. In a sprin attachment for boots and shoes, a base p ate having a socket at one end, a movable plate having a tongue engaging said socket, springs interposed between the base plate and the movable plate, and connecting means such as a bolt connected with the base plate and extending through a slot in the movable plate and having a nut whereby the movement of said movable plate may be limited.

2. In a sprin attachment for boots and end and provi shoes, a base ate having a socket at one died with projections or brack- I $9 8,951. a f

the movable plate with secured upon the base plate, a p

Inovable plate having guide lugs en aging the pro'ections upon the base plate an provided wit a bail, and a bolt extendin through the base plate and through the bai of the movable plate and having a nut to limit the movement of said plate.

In testimony whereof, I afilx my signature in presence of two witnesses;

Witnesses:

JAMES F. DUHAMEL, IRVING J. KING.
