IMPROVEMENT IN' BOO'I' AND SHOEHEELS.

'The Schedule referred to in these Letters Patent and making part of the same.

To all whom it 'may concern: v

Be it known that we, HENRY F. HARRIS and GAY- LoRD'P. PINNEY, of Chicago, in the county of Cook and State of I llinois, have invented'a new and im-V proved Boot and Shoe-Heel; and we do hereby dcclare the following to be a full and exact description thereof', whichwill enable others skilled in the art to which ourinvention appertains to make and use the same, reference being hadto'the accompanying drawing, forming part of this speciiation.

Figure 1 is a perspective view ot' the-lixed part of a boot or shoe-heel, showing one of the metal plates by which the two parts of' the heel are connected together.

Figure 2 is a perspective view ot' the removable part of the heel, also showing a metal plate.

Figure 3 is a vertical sect-ion of a boot-heel, showing the application of our improvement-s. A

, Figure 4 is a perspective view of the key for locking and unlocking the heel.

Similar letters of reference indicate corresponding parts in the several figures of the drawing.

The heels of boots and shoes, owing to their construction, almost invariably wear unevenly, thereby frequently destroying their symmetry, and also that ot' the shoe,.bet'ore either are worn`out.

To overcomethis defect, heels have been employed pivoted to the shoe in such amanncr as to be capable ot' adjustment, for the purpose of changing the wearingsurfaces.

The objection found to this construct-ion of heel is, that it cannot be held firmly in place at any desired point of its rotation, and is, consequently, liable to become loose and drop oh, or, when changed, to move hack to its first position. The effect of the adjustahiiity is, theretbre, entirely lost.

Qur invention has for its object to provide a reveiving boot and shoe-heel capable ot` Abeinglocked timely in position at any point ot' its adjustmentand tu this end,

The invention consists in the construction and arrangement of parts by which this result is obtained, as will be hereinafter more fully described.

In the accompanying drawing- A is the fixed port-ion ot' a boot and shoe-heel, made circular in shape, and atlixed to the shoe, B, in the usual manner. A

The portion A is made about hall` the height of the entire heel, and is provided, upon the bottom, with a circular metal plate, O, firmly aixed thereto by means of screws, as shown.

rIhis plate may be equal in diameter to the portion A, or made somewhat smaller, and let into said portion, as shown in fig. 3.

D is an angular boss or nut, formed upon the plate, and projecting downward from the center ofthe same to ht within a corresponding angular opening formed in the center of the circular met-al 4plate F, iirmly secured in any convenient manner to the inner surface of the rotary portion- Gr of the heel.

lhis latter portion ot' the heel is also `made with a circularexterior, to correspond with the part A.

The plate F is also, in this' example of our invention, somewhat smaller, diametrically, than the part G, and is let into the same, as shown.

H Ais a metallic washer, placed in the part G under the plate F during the formation of the heel.

The two parts of the heel are secured together in the following manner:

. The part G is placed upon the part A, with the.

boss D of the latter entering the central opening in the forme-r, and a headedsercw, F, is inserted through a central ope'ning. J, formed in the part G, passing through the washer H, and the boss or nut D, as shown in iig. 3.

The screw is set firmly down, to hold the parts together by means of aI key, 7g, shown in iig. 4, which over the squared end of lthe screw for this purpose.

When -t-he screw is vin place, its head, m, bears against the washer, as shown, and thus forms a firm connection ot' the parts.

N is a small disk, of leather," insertedv in the opening formed in the part Gr of the heel for the passage of the screw. vIt is supported upon the end of the latter, and serves to close the 'opening against the introduction of dirt, Sto.

By constructing the boss with angular sides, and the recess in the plate F with corresponding angles, theirevolving part G of the heel is prevented from turning when locked in place by the screw. v

We design to form the boss and recess octagonal in shape, to admit of' the revolving heel being changed and locked firmly in eightditerent positions.

.It will, otl course, be understood that the screw is loosened by the key after the disk N is removed, to permit the various changes ot' the part Gr.l

By our invention a revolving boot and shoe-heel is produced, which is adjustable to compensate for -uncqual'wear, and, at the same time, secured firmly in place at each point of the adjustment.

Having thus described our invention,

What we claim as new, and desire to` secure by.

Letters Patent, is`

In combination with the plate O, having the anglilar screw-boss D, and the plate F, having the angular opening, the tixed washer H and anged screw I', all constructed and arranged to operate within the fixed and removable portions A G of the heel, as herein shown and described, for the purpose specin'ed.
