METALLIC HEE ronnoors on snons.

To all whom, it may concern Be it known that we, JAMEs J. MULCON- Roy and EDWIN S. MORRIS, both citizens of the United States, the former, residing in the city and county of Philadelphia, State of Pennsylvania, Oak Lane, Montgomery county, State of Pennsylvania, have invented a new and useful Metallic Heel for Boots or Shoes, of which the followin is a specification.

Our invention relates to a novel construction "of a metallic heel for boots or shoes, which will be more durable than other forms of heels heretofore in use, and which will keep. the counter of the boot or shoe from breaking because of the heel wearing or becoming crooked, which is now usually the case in ordinary leather heels. i

In the ordinaryboot or shoe construction,

adapted for heavy work or inclement weather, such as miners, laborers, farmers or the like wear, it has been heretofore customary to attach a and when the back or side of the heel wears down, so that the heel becomes crooked or worn at one side, an undue strain is brought to bear on the counter and vamp of the boot or shoe, and heels of this character must be frequently repaired, at considerable expense.

Our novel construction of metal heel will not add to. the initial expense of theboot or shoe, and will not wear down at the rear or one side thereof, as will, the wood or leather heels now in use, and our novel heel may be either stamped out of sheet or other metal, or it may be cast from any desirable metal, such as malleable iron, bronze, brass and the like. It may be made hollow, so that its weight is approximatelv the same as an ordinary leather heel, and it may be round or any desirable shape, as may be desired.

Our invention further consists of a novel construction of. metallic heel for boots or shoes, having a crescent or other shaped strip of soft material such as Babbitt metal securely interlocked with the base of the heel, whereby slipping of the same may be prevented.

Our invention further consists of a novel construction of a metallic heel having an extension projecting from the breast of the heel to fit along the leather or rubber sole so as toprotect the latter, and prolong its life when the wearer is spading with a shovel or the like, said extension being a Specification of Letters Yatent.

and the latter residing at heel, constructed of wood i Patented July 14,1914.

Application filed September 26, 1913. Serial No. 291,937.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose ofillustrating our invention, we have'shown in the accompanying drawings one form thereof which is at present preferred by us, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which our invention consists can be variously arranged and organized and that our invention is not limited to the precise arrangement and organizationof these instrumentalities as herein shown and described.

Figure 1 represents a perspective view of a metallic heel for boots or shoes embodying our invention, showing the heel inverted fromits normal position when in ordinary use. Fig. 2 represents a view of the top of the hollow metallic heel seen in Fig. 1, showing particularly the reinforcin members, and the means for securing the heel in position. Fig. 8 represents a bottom plan view of Fig. 2. Fig. l represents a section on line'ae-w, Fig. 1. Fig. 5 represents a perspective view of a rubber, leather or other boot, having our novel heel with the exten sion from the breast thereof applied thereto.

Similar numbers of reference indicate corresponding parts in the figures.

Referring to the drawings: 1 designates our novel construction of metallic boot heel, the same being hollow and comprising the bottom or base portion 2, having the front or breast portion or wall 3, from which may project the extension l, which protects the leather or rubber sole 5 of the boot 6, as will be understood from Fig. 5, or, if desired, the extension 4 may be omitted, as seen in Figs. 1 and 2. From the base 2 projects the curved wall or side 7, whereby a pocket 8 is formed, having the curved, inner walls 9, provided with shoulders 10, from which extends the curved, inner thickened rear wall 11, the latter extending down to .the arc-shaped, reinforcing or thickened member or strip 12, from about thecenter of which extends the central lug 18, having the screw hole 14Etherein, while the lugs 15 with the screw holes 16 therein are located nearthe ends of the strip 12.

17 designates the corner lugs having the screw holes 18 therein, for the reception of suitable screws or other fastening devices, 19.

20 designates a strengthening rib, which is shown as extending longitudinally of the pocket 8, but the location of this rib may be varied, and a plurality of such strengthening ribs may be employed, if desired. At the rear of the base of the heel, we locate a curved or crescent shaped dovetailed recess 21, preferably of the contour seen in Fig. 4, into which is poured a soft metal 22 such as Babbitt metal or the like, which will prevent the heel from slipping when in use. y

We preferably make the dovetailed recess of such shape that acurved wedge-shaped head 23 is formed, which securely interlocks with the contiguous portion of the metallic heel.

It will be understood that the strip of softor Babbitt metal 22, seen in Figs 1 and 4, may be of other shape than the crescent shape, and that the same may be omitted,

if desired, and different surface designs may may be employed to meet various conditions,

since the heel may be made with projectionsof a pyramid or hemispherical contour, or depressions or other designs may be employed, to give adde'dwear or to meet pe-,

' the present instance as being secured in posi tion by screws, it will be apparent that other fastening devices may be employed, without departing from the spirit of our invention.

By theemploymentof the thickened lugs 18, 15 and 17 it will be seen that the necessary strength is given to the reinforced parts at the points where the screws are inserted, and it will'be apparent that our invention is applicable to any type of leather or rubber boots or shoes, and it is especially applicable to rubber boots having leather soles.

It will be apparent that our novel construction of metal heel can be cheaply manufactured in large quantities, by being stamped out from a die, or we may employ an iron heel made from acasting, if desired, and that the heel may be constructed from any suitable or desirable metal, such as sheet steel, malleable iron, brass, bronze or the like. i

Itwill now be apparent that we have decopies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

vised a new and useful construction of a metallic heel for boots or shoes, which embodies the features of advantage enumerated as desirable in the statement of the lnvention and the above description, and while We .we claim as new and desire to secure by LettersPatent, isz- I 1. As an improved article of manufacture, a hollow metallic heel having a closed bottom extending across the same and forming U a flush tread. and means, sunk into the metal forming the bottom and forming together a level surface, for

preventing slipping When in use.

' 2. As an improved article of manufacture,

a hollow metallic heel having a closedbottom extending across the same andforming a flush tread and with a recess formed in the rear portion thereof, and a filling 'ofsuitable material in said recess and'intcrlocked with the metal forming the bottom,tin such manner that the larger portion of the metal wearing surface and the said material contact with the ground.

3. As an improved article of manufacture,

a hollow metallic heel having a closedwearing surface and formed with a recess in the rear portion thereof, and a filling of metal of a different characteristic from that forming the heel held in said recess.

4. As an improved article of manufacture,

a hollow, metallic heel, a crescent-shaped. depression in the back thereof and a filling of soft metal in said depression and interlocked with said heel.

5. As an improved article of manufacture,

a hollow, metallic heel having a recess therein, and a filling of soft metal in said recess and interlocked with said heel.

6. As an improved article of manufacture,

a hollow, metallic hee'l having a closed wearing surface, and a reinforcing strip at the rear thereof, said heel having a recess formed near the back thereof and in said strip, and a filling of soft metal in said recess and in- I terlocked with said wearing surface and strip.
