VENTILATING-CUSHION FOR FOOTWEAR.

Toall who/m it may concern:

Be it known that I, 'FRANCIS J. Dnomsxr, a citizen of the United States, the borough of Brooklyn, county city and State of New York, have invented certain new and useful Im rovements 1n Ventilating- Cushions for ootwear, of which the following is a specification.

My invention relates to a cushion adapted for insertion within a boot or shoe or other article of foot-wear, and has for its object to produce a cushion which will be elastic and. resilient, and will therefore provide against a transmission of shocks in walking, etc.

A further object of Amy invention is to produce a cushion which will have the effect of Ventilating the article of foot-Wear to which it is applied.

A desirable mode of carrying my invention into effect is illustrated in the accom'- panying drawings, whereinr,

Figure l is a longitudinal section of a portion of a shoe having' one form of my invention in place; the section linee of the cushion being on the line 1-1 ofe Fig. 3; Fig. 2 is a perspective view of a cushion in which my invention is embodied Fig. 3 is a horizontal section of the device shown in Fig. 2; Fig. 4 is a detail front view of the cushion illustrated in Fig. 1; and Fig. 5 is a `cross-section on the line 5-5 in Fig. 3.

The particular embodiment of invention illustrated is a heel cushion wherein the air passages are ,situated at the front of4 the cushion. The invention is of course equally applicable to cushions which will cover the entire bottom of the shoe, and which will embody the same construction illustrated in the drawing, and therefore to avoid duplication I have illustrated s'uch cushion separately. The air passages may be variously disposed to suit the particular size or shape of the cushion.

My invention as illustrated employs two an upper plate A and a lower plate are connected by a series of hollow columns C. lPreferably the entire structure is composed of some 'elastic and resilient material, for which purpose soft vulcanized rubber is well adapted, and in such case the columns C will be formed of thesame material and will be vulcanized to the upper and lower plates. The form of such columns Specification of Letters Patent. Application filed March 31,1911. ,Serial No. 618,071.

them to remain in extended .position permits malntain the plates separated, as

and to illustrated in' Fig. 1', while at the same time they readily yield under pressure and collapse without injury.- In this particular the hollow columnar supports are a great im'- provement upon the solid support, which does not collapse so readily and is apt to break. The said plates are closed about the1r .edges byy a front wall D anda side wall E, which closes -bo-th sides and the back of the device.

The front wall of the cushion is provided with passages d which lead-from the exterior into the interior of said cushion, and by reason of the fact that the structure comprises a collapsible to which are the said passages, a bellows is thereby produced which alternately forces air through the said passages d into the shoe and withdraws the air from the shoe into the receptacle orcushion. A highly desirable circulation of air within the shoe and ventilation thereof is thereby attained.

The longitudinal section, Fig. 1, shows that the device is slightly convex longitudinally upon its upper surface, and tapers from front to rear, the'least thickness being at its forward end, and this in combination surface transversely as illustrated I have found furnishes a desirable I do not regard the same as eslower plates. in the upper and lower plates as in the coll umns is not essential, but by reason vof the fact that a more desirable connection between the columns and the plates, and also box, the only openings ould therefore be connected- -by an air-tight connection-to the upper and The same degree of flexibility with a certain amount of convexity upon the side walls and the front, may be had if all of the ,said parts are formed of rubber and vulcanized together, I prefer to make the entire device of soft vulcanized rubber. Therefore should the said device be entirely made of soft vulcanizedrubber to overcome any objections. which might arise' from the inuence of the rubber` u on the foot of the wearer, I may provi e a leather insole F My invention isl not necessarily limited to the precise form, 'shape or relatlve arrangement of parts illustrated, but is subject to variations and modifications thereof within the limits of the appended claims.

I claim as my invention l. A cushion for shoes comprising upper and lower plates each formed of an lntegral iece'of soft rubber, and hollow columns lbcat'ed perpendicularly to said plate-s and each connected to` both of said plates, said columns formed of soft rubber and said plates serving to clo-se said columns and form independent air 'cells in each column and, to maintain said columns in position.

2. A cushion for shoes comprising upper and lower plates, a vertical wall connecting said plates at their edges, and hollow columns formed of'elastic and resilient material and connected to both said plates,

whereby said columns form air cells adapt-- ed to return said plates to position after compression, andare maintained in place by said plates, the wholeconstructed of soft rubber andsaid top and bottom plates and vertical wall connected by an air tight connection and forming a'bellows-like structure and said structure provided withvau opening for the passage of air.'

3. A cushion for shoes comprisingupper and lower plates closed at their edges, and i hollow columns eachv connected to both of` said plates, the whole formed of soft rubber,

nected to said plates, the whole formed of,

soft rubber vulcanized together and one of said walls being provided with an air passage formin a bellows-like cushion.

' 5. A cushion for shoes comprising upper 'and lower plates, hollow columns each connected to both of said lates and walls connected to said plates orming an inclosure, the whole formed of soft rubber vulcanized together and the front wall of said structure being provided with an air passage.

6. In a cushion heel,'top and bottom plates connected ,at their edges forming an air chamber between them, posts interposed between sai plates and connected to one of said plates adapted to restore' said plates to separa d condition after compression, said posts andthe plate to which they are connected being formed of soft rubber vulcanized to ether, and the said structure being provi ed with an opening at its front end and` forming a bellows-like cushion.
