RUBBER HEEL.

Application filed October 24, 1922. serial No. 596,585.

To all whom it may cancer n:

Be t known that I, HUGH T. HUGHEs, a

citizen of the United States, and resident of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain 'new and useful Improvements in Rubber iconcaved transversely, and broken by a multiple member of -concentric riclges sepa- .rated by grooves which ho-Wever do not ernerge at the sides or ends of the lift -but are terminated by marginal walls, in such a manner as to form suction pockets or vac- .uum cups, tending to retain the lift in its place.

-The ribs' separating these corrugations may have vertical or inelined sides and are so arranged that the nails may he driven through any of them, at any clesired distance from the mal-gin of the lift thus ena'bling ,the shoemaker to cut of any amo unt of the margin necessary to fit the rubher heel to any desired size of leather heel, and

enabling him to reduce the amount of stock kept on hand.

,In thisconstructionwhen the edges are drawn flat against the heel they cannot she pulled down, and separated from the body of the heel.

Also the gnooves tend to make the heel more resilient underfoot than if the substance of the lift were solid throughout. Also thenail's are held in place -by means ofa Wire netting which permits the lift to he evenly drawn flat, and one'nnil will hold the lift in place until other nails can be' The inventio'n is hereinafter more fully described shown in the accom. anyig 'drawing' and specifically point `out the clains. i

In these views, A rep esents a lift formed of rubber or resilient composition, the lower surface of which is provided with concentrio ridges, B, B, alternating with grooves, v I

B', B', which terminate in at the front wall, C, the upper surface of which is level with' the heel.-

The sides of these groojves are preferably inclined as at D, D, on the inner side, and vertical as at E, on the outer side, and the ridgcs are preferably terminated by flat surfaces, F, F, and a central longitudinalridge is provided, With a flat surface, .F'. These sul-faces are drawn tightly against the bottom of the heel by means of nails inserted through the ridges. The gr'ooves between the ridges then become air pockets which serve to cushion the weight upon the heel and relieve the foot and ankle of the 'wearer from Shock when thelift is nailed in place. hen nailsare driven through the central longitudinal rit), the ri-b serves as an a'butment `preventng the Collapse or further compression of 'the heel that would take place if the cavity should extend past the center of the heeh i A wire netting, G, is employed to prevent the` lift from sli ping over the head's ofthe nails driven in t e openin'gs, H,:and has the advantage that a single nail centrally driven will hold the entire lift` closely. in place and until the` :other nails can ibe driven, thus being much more eflicient than washers.

Tle bottom of the heel may flat, as

'shown in Figures 3, 2 and 5, 'but may he since the rear end' is` the first to become worn. Also it eliminates the hecessity of additional lifts. This makes the reale of the heel 'gher and on a level with the hall of the f ot.

The solid level .center supprortsthe weight revents thejyedges om collapsing in shap'e and prevents the admission of -ir intothe The thin marginal edges, when pressed down upon theleather heel, remain tight and prevent dirt from enter-ing, and do not separate from the leather. i

In Figs. 4 and 5 the heel is shown having a general eoncavity in 'one transverse direction only. This insures a perfect fit upon the leather heel. I

The raised or inclined ed 'es, F, and F', of the ridges, receive the nails and thus permit the onter edge to be pared off by the shoemaker from ridge to ridge to fit heels of different sizes, and the ridges are so spaeed as to permit such action. For this reason, a fewernumber of h`ee1s can be kept in stock,

one heel serving for several sizes of heels.

-When intermediate sizes are desired the nails can be driven through the inclined sides and a fibre w asher perforated for'nail holes can be employed which can be cut when pal-ing the sides of the hee1.'

In Fig. 7 a heel tapered togive increased thickness in the rear at A' is shown in connection with a smooth upper edge and longitndinal o'penings B' which are deepest' in the rear to give inereased rcsiliency to the thick portion.

The openings taper Upward at 13 in front.

Having described 'the invention, what I claim as new and desire to seeureb'y Letters ratent is:

1. In a rubber heel, a body having its npper surface provided with a margial ridge, on its sides and,rear end, and a transverse ridge on its front end, and with inner ridges parallel with the sides and rem: end

thereof, and terminating in said transverse front ridge, and with grooves between sad side and rear ridges, said side and rear ridges having slopinginner faces, and the bottoms of said grooves sloping upwardly towards said front ridge, said ridges being spaced apart to permit division of said heel upper surface provided with a marginal rdge on ts sides and rear end, a central longitndinal ridge, and a transverse ridge on its front end, and also provided with inner ridges arallel with the sides and rear end thereof, and terninating in said transverse front ridge, and with groovcs between said side and rear ridges, sad side and rcar ridges having 'sloping inner faces and the bottoms of sad grooves slopng upwardly toward' sa d front ridge, said rdges'beng 'spaced apart to permit division of said heel into different sizes,1 said ridges being lon'gitudinally inclined upon their upper surfaces, and said central longitudinal ridge serving to prevent the Collapse of said hee] when said heel is secured to the shoe.

In testimony whereof, I hereunto setmy hand this 2151; day of Oct. 1922.
