act description.- .v

y This vention relates to shoemaking.

The object of the yinvention is to produce a shoe'having a pneumatic cushion which will o eratefto'give elasticity to the tread and a shoe. y A

"'Theinvention -consists in the construction and'eombination of parts to be more fully described hereinafter and'particularly set forth inthe'claims.

'Reference is to be hadl to the accompanying drawings, forming a part, of this specification, in which similar charactrs'of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal section taken in a` vertical plane at the heel of the shoe constructed.` with my pneumatic. cushion. This v section is takenion the line 1 1 of Fig. 3- Fig.

2 is a section taken substantiall on the line 2 2 of Fig. 1,- and-looklng upwar y, and Fig. 3 is agvertical section' taken on the line 3 3 of Fin. i x(Ieferring more particularly to theparts, 1

represents the of the heel, from which the' 'shank'2 of thesole 3 extends-forwardl as shown. This portion of theshoe may e of I counter 4, which attachesaround the edge of i the sole at the heel. -the sole 3 Ifplace an msole 5, .the body 6 the usual construction, comprising the usual U on .the inner face of whereof consists, preferably, of a canyas ieee .cut to the proper last. At the heel this msole is supported upon my pneumatic cushion 7. 'This pneumatic cushion com rises a body or pad 8, preferably formed 'of ru ber orsim'ilar. elastic material. This of athin sheet 9 ,preferably of ru under face whereof I forma plurality of ribs or corrugations designated collectively by the numeral 10. These' ribs 10 are of elon-V gated horseshoe form, as indicated most clearly in Fig. 2, comprising oppositely-disposed limbs 11, whic j and which are connected byb'ows 1'2 at the rear; Certain of these ribs, such as' the ribs 10, are of greaterheight than the others and pro'ect below the same, so that the nor' ma y is disposed,fas shown in and 3.

o assist in Ventilating the interior of the 'such as steel. shown' most clearly in Fig. 2.

'converge forwardly Application filed December 13,1905. Serial No. 291,592.

In. this'way an air-space 13 is formed under the pad and between the sheet 9 andthe upper ace of the sole- In addition to4 the ribs '10 I provide the sheet 9 with a 'downwardly-projecting iianlge 14, which extends alongfthe outer ed e lof same, as shown. At the front this ange 14 extends transversely of the sole, formin'ga bar 14a/of reduced height, and at the rear and sides it. lies close against the inner face'vofethe counter, as indicated most clearlyin Fig. 3.

Itpreferably ta ers sli htl toward its lower P i Y extremity. Between t e ribs 10 referred to labove and between the said ribs and* the flange 14 I provide -intermediate ribsor conrugations 10b, which are substantially similar in form tothe ribs 1'0", but do not project l downwardly to such an extent.

v To the under side vof the sheet 9 I attach a frame A16, preferably .formed of light metal, e form 'of this frame is It comprises oppositely-extending arms 17, which incline forwardly, as indicated. From their oint of juncture a tongue 18 extends rearwar ly, and this tongue constitutes aleaf-spring, as indicated most clearly in Fig. 1, and rests upon the under side of the sheet 9, tending to su port the same. The outer extremities of t e arms 17 are connected by a bow 19, which lies in the space between rtwo of the. adjacent corrugations', as shown in Fig. 2. This bow is also resilient and presses downwardly at its extremity upon the upper face of the sole. The function of this frame will appear more hereinafter. v l e upper face of the Asheet 9 is attached to a .sheet or strip 2() of suitable fabric, such as canvas, the parts bein cemented or connected together in any suitable manner. U on the up er side of this canvas sheet and etween 1t and theaforesaid insole 6 I place a sliver 21, preferably of cork, and this sliver tapers toward its forward extremity so'that it comes substantially tol an edge atv the for-l ward extremity of the pad.

IOO

When ressure comes upon the heel of the A shoe, as m walking, the cushion 7 becomes essed' by the'weight above. The air inclosed b the flange 14 operates as an aircushion w en compressed. As the greatest pressure-is exerted towardthe heel, a quantity ofthe entrapped air is forced forwardly .underlthe bar 14.

The ribs 10 assist'in con- -tracting the air-space by expanding under 1 pressure and -tend4 to force the air forwardly. v i

return the cushion to its normai Condition'.

. claim es new and desire to' seeure by Letters While the lintermeriiete ribs 1G" assist in this operation to si eer'tein extent, they substantieiiy arrest the downwardmovement of the heel of the foot. As soon es the weight is removed from the heel es e step is teken the spring or tongue 18 und the bow 19 operate to In this wey the eil which has been forced forwardly, es described, will find its wey beck under the heel-pad. Evidently in walking;A the cushion operates to 'produce a good ven.- tiiation within the interior of the shoe, While at' the same time it cushions the vshock and jar ofthe heel when 'it comes upon the ground or pavement.' The siiver or cork? operates to i absorb the'rnois'ture which ma be given 'off by the foot within tho' shoe en 'this of course has opportunity to dry out et night when the shoeis remove 'y y I Having thus `described I my invention, i
