SPECIFICATION formingpart of Letters Patent No 746,338, dated December 8,, 1903..

Application filed November a. 1902. Serial No. 130,328. on model.) i I To aZZ whom, it may concern.-

Be it known that I, FREDERICK W. KEEN, a

ed certain new and useful Improvements in Anatomical Guards, Boots, or Pads, of which the following is a specification, reference being had therein tot-he accompanying draw- 7 ings, which form a part thereof. My invention relates to anatomical guards, boots, or pads, and more particularly to a class thereof especially adapted to be applied to and protect certain exposed bony-portions of the body under various conditions.

The object of my invention is to provide a guard, boot, or pad of this class which will readily conform to the part to be protected, which will present exteriorly a cushion which will not only relieve the part to which it is.

attached from the effects of blows or contact with other parts or substances, but will also mitigate the effects of such on the interfer-,

ing part, and which may readily be applied.

A further object isto provide a guard, boot, or pad the cushion of which may be regulated to meet different requirements and the exposed portions of which are sheathed or rein-forced to protect the cushion proper, and thus preserve the flexibility or elasticity of the latter and prevent accident thereto resulting in'its deflation.

- The invention consists in those novelfea- 'tures of construction hereinafter set forth and described, and more particularly pointed out in the claim hereto appended.

Referring to the drawings, Figure 1 is a side elevation of an-athletes shoe embodying my invention. Fig. 2is a similar view thereof, showing the facing turned back to disclose the pocket and the contained airbag. Fig. 3 is a front elevation thereof. Fig. 4. is a front elevation of a boot or pad for a horse embodying the invention. Fig. 5 is a cross-section thereof, showing the pocket and the contained air-bag in elevation; and Figs. 6, 7, and 8 are views of different forms of airbags.

Like letters refer to like parts throughout the several views.

adapted to conform to the contour of the part to which it is applied, provided with means whereby it is secured in the desired relation. This base is providedwith a facing having an opening therein adjacentto the most exposed portion of the part to be protected and' coincident with that portion of the guard, boot,*or pad which is liable to the greatest wear, and a concave metal plate is secured in this openingby any desired means, as or dinary stitching alone or in con-junction with a facing-strip. In the pocket or sac'so formed is seated an air-bag, which is interposed .between the flexible base and the facing referred to. This bag is provided with a'tube exterior to both the base and the facing to facilitate the inflation of said bag.

Referring more particularly to Figs. 1 to'3, inclusive, the invegtionis shown as applied to an athletes shoe. In this embodiment of theinvention-the lining a of the upper constitutes the flexible base-adapted to conform to the ankle of the wearer. The said base is secured to the ankle and foot of the wearer by means of the ordinary vamp b and lacing.

(Not shown.) The leather upper o is sui'ficiently large to form a pocket or. sac d between it'and the lining or base a, in which is seated an inflatable air-bag e, provided with an air-tube f. This bag conforms tothe pocket (1 sufficiently to prevent its undue eX- pansion and the resulting loss of air-pressure. Directly above the point where the anklebone of the wearer will be the upper c has an opening-g therein of sufficient size'to include the most exposed area of said upper both with relation to the part to be protected and the blows thereon to be anticipated. This opening is closed by a concave plate h, of aluminium orother light tough metal, which is socured in position by means of openings adjacent the edge thereof and ordinary stitches.

The precise means of securing this plate in position, however, are immaterial to the invention. The plate 71. serves to protect the air-bag e from the effects of spikes, blows,

&c., and at the same time in case of the defiation or partial deflation of the bag will protect the ankle-bone from the effects of such accidental blows or spiking. The general shape of air-bag e is shown in Figs. 2
