Application fled" October 25. 196i. Serial No. 229,952.

To all whom t .may concern: Be it known that I, WILLIAM J. Hannie a citizen of the United States of America, an a resident of Philadelphia in the county of Phili adelphia and State of Pennsylvania, have invented certain new and useful Improvements in Horseshoes, of which the following is a specification. 1 l

My invention relates to certain new and useful improvements in horseshoes, peeially relates to means for removably sel curing thereto calk's.

For this pur cse it consists in dovetailed grooves forme br bottom of the shoe and adapted to receive correspondingllyshaped calks, and to means e calks therein, and to the construction of the calks themselves, whereby v they may be, when Worn, removed and shifted or turned, whereby the life. of thecalks is lengthened, land whereby, owing to the removable nature of the calks', calks of desired contour may be fastened to the shoe, as may be desired from time to time, all without removing the shoe from the foot; and it further consists in the construction, arrangement, and combination of the several parts of which it is composed, as will be hereinafter more fully described and claimed.

Referring to. the accompanying drawings, in which corresponding parts are designated by similar marks of reference, Figure lis an inverted plan View of the horseshoe having my invention applied thereto. Fig. 2 is a section on lines 2 2 of Fig. 1. tailld sectional view illustrating one form of ca The horseshoe A ina be of any approved shape and made in any esired manner, except that for the purpose ofcarrying out the por2 pos of this invention I form in the lower surace thefeof 'at the points to which it is desired to secure ea'lks, dovetail grooves a, which are vviderat the bottom'ith'an at the top and which by preference and for ease in forming havebothof their ends extending tosisf Walls of the shoe. In the accompenyin drawings I have shown these grooves locate 7 A atthe toe andheel ofthe shoe to receive toe and heelealks, whichlare the points atwiiich calk's are commonly lbceted the toeo ove oe on one side ofthe toe tothe outer wali'of the shoe on the other side 'of' theA toe while the heelooves extend across the heelsvzof the shoe om the outer to the inner walls thereof.

and it esat proper points in the solej 3 is a de- The calks are formed of suitable metallic pieceshaving their lower parts adapted and shaped to conform to the grooves e, in which the are l to be incased. By preference I ma e the ealks B isee Figs. 2 and 3) with a cross-section in the form of an equiateal triangle, any side of which may form the base and be received within a groove a, of the shoe, so that should the angle opposite to anyV such base side become doll the oalk can be removed and turned around, so as' to present a fresh an lent the point of the ealk.

Y he fastening device for the calks consists of a depression b* in the side of the calk near one edge, into which the malleable metal of the shoe is ada ted to be forced to prevent movement of' t e calk in the groove. By reference each side of the calk, as is shown in Figs. 2 and 3, is provided with of these de fassions, the depr symmetries. ly arranged on eac Y, is to say, beingV adjacent on each ace to the successive edges and being spaced lengthwise on the calks at different points, so that whatever edge of the ealk may be placed u wardly a depression'will be on one of itssi es adjacent to its base, so that if when the calkis turned to bringsuceessive edges as the edge ,of the call: the depressions to be clam ed will be at different points' along the lengt 1 of the roove, thus permitting the lip which may ave been forced down a depression to be cut ont 1when it is desired to tnrn the calk without impairing the ability to refasten the calk in lace when turned. Y Y

t will be seen that" all forros of my invention provide for a calli that mar beremoved and replaced without the neeV of special tools, so that thelifeof the shoe itselfis prolonged, and that this is irrespective ofthe form of fastening 'that may beV employed, and any of the forms herein shown are applicable with the equilateral cross-seetionpdeseribed, such cross-section permitting the repeated use of the calli, and that the tapered form of caik rovides a feature of safety which is of great nn ortance. Y Y c aving thus described my invention, what I claim, and desire to secure by Letters Patent 'of the United States, is-

1 The combination with a horseshoe havin(r a dovetailed groove in the lower face there@ of a calliA removabl secured in the said groove, the talk having an equilaterai crosssection, with depressions synunetricallyl dass.

posed upon each of its faces, spaced at dille?- ICO xogt

eut points along its length, into which depressions the metal ofthe-shoe may be forced, substantially as described.

2. `The combination with s. horseshoe having a dovetailed groove in the lower fece thereof, of a cslk removably secured inthe said groove, the calk de tensions sym-f metrxcally dis osed upon esc of its faces, spaced at difl'srent point.. along. its length,

into which de ressions the metal ofthe shoe lo ma be force substantially as described.
