THOMAS J. LEVEY, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR OF ONE-THIRD TO THOMAS R. NALLEY AND ONE-THIRD TO RICHARD EDELINE, OF WASHINGTON, DISTRICT OF COLUMBIA.

HRSESHOE To @ZZ whom it may concern:

Be it known that I, THOMAS J. LEVEY, a citizen of the United States of America, residing at Washington, in the District of Columbia, United States of America, have invented certain new and useful Im rovements in Horseshoes, of which the fol owing is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in horseshoes, and particularly constructions having removable heel and toe calks.

Among the objects of my invention, are the provision of a horseshoe of this type in which the calks are readily attached and detached in which the calks, when in position, are securely locked against movement relative to the main portion of the shoe; in which the locking means for each calk consists of a single metallic element; in which the shoe and calks have complemental surfaces adapted to position the calks in proper location to receive the locking means; in which the calks may be attached to or detached from the shoe while the shoe is in position, on the animals foot, and in which `there is no liability of any of the removable parts of the shoe being forced into contact with the foot of the animal in use.

Other objects are to provide a construction of shoe and calk which is vsimple and eflicient in operation, durable in construction, and which is of relatively low cost of manufacture.

To these and other ends, vthe nature of which will be readily understood as the invention is hereinafter disclosed,`said invention consists in the improved construction and combination of parts hereinafter fully described,'illustrated in the accompanying drawings, and particularly pointed out the ap ended claims. i i

In t e accompanying drawings, in which similar reference characters indicate similar parts in each of the views-#Figure 1 is a perspective view showing ya horseshoe and calks constructed in accordance with my inven- Specfication of Letters Patent'.

sition. Fig. 2 is a sectional view thereof, taken in line 2-2 of Fig. 1, and also showing the heel of the shoe and its heel calk in section. Fig. 3 is a perspective detail view of the toe portion of the body of the shoe. Fig. 4 is a perspective view of the toe calk. Fig. 5 is a erspective View of one of the heel portions o i the body of the shoe. Fig. 6 is a perspective view of one of the heel callrs. Fig. 7 is a detail view of a modified form of heel calk.

10 designates the body ortion of the shoe having a substantially at upper surface and being of substantially equal thickness throughout its length, the shoe being provided with the usualnail-openings 11. The toe portion of the body 10 is provided on its periphery with two vertically extending portions 12, the inner faces of which are adapted to contact with the foot of the animal, said portions being spaced substantially equi-distant from a line drawn centrally through the shoe from toe to heel, said portions serving the purpose of the single projection generally found on shoes.

For the purpose of receiving the toe-calli presently described, the toe of the body portion has its inner face beveled, as at 13, the

inclination extending forwardly toward the top plane of the shoe, thereby forming two surfaces having their lanes crossing each ane of the shoe, said surface planes eXtendlng at acute angles relatively to `each other. The outer face of the toe of the body portion is also beveled, as at 14, said beveled face being substantially parallel with the face 13, said face, however,

being of lesswidth from its bottom to its upper edge than the Width of the face '13, the upper edge of the face 14 being at a point intermediate the top and bottom planes of the shoe. That ortion of the outer face of the toe located a ove the upper edge of the face 14 and indicated at 15, extends verti-l cally in a line at direct rightangles to the plane of the top surface of the shoe. Each of the beveled faces is located substantially tion, the calks being shownin operative po. l central of the toe portion, the face 14 being of less length than that of the face 13. The

toe portion is further provided with two forwardly extending lugs 16 spaced apart a distance equal to the length of the face 1.4, said lugs having a width equal to the distance between the top and bottom edges of the face 14, the opposing faces of said lugslbeing parallel with each other and extending 1n directions at right angles to the plane of the face 15. By this construction, the inner and outer faces of the toe of the shoe are provided with o posing shoulders on opposite sides of a line ilrawn centrally and lengthwise of the shoe, said shoulders forming abutments against a lateral movement of the toe calli, as presently described.

. Each heel portion of the shoe is cut-away, as at 17, on its bottom face, and has its inner and outer face beveled both vertically and longitudinally, the inclination being inwardly from the bottom to the top planes of the shoe and from the forward to the rear planes of the cut-away portion of the heel, the inclinations of the inner face being 1n opposition to those of the outer face, thereby providingr one member of a dovetail construction, the op osing member being carried by the heel calli, as presently described. The under face of the heel portion is also provided with a recess 18 for a purpose presently described.

The toe calli 20 consists of the body portion 21 and the positioning and securing portions 22 and 23. The main portion has a generally Hat upper surface which is adapted to contact with the bottom face of the toe portion of `the shoe as shown in Fig. 2, the

' is provided.

front of the portion 21 having a downwardlyextending portion of suitable configuration to form the calk proper, that part of the portion 21 lying in the rear of the calli proper being of sufiicient thickness to support the portion 22 and of a width substantially equal to the distance between the opposing shoulders located on the inner face of the toe of the shoe heretofore described. For the purpose of further strengthening the rear part of the portion 2] a web or rib 24 (shown in Fig. 2) The portions 22 and 23 are formed integral with the portion 21, the portion 22 being in the form of a verticallyextending lip 25 the inner face of which is inclined to complementally fit the face 13 of the shoe, said lip, however, having the vertical length of its inclined face less than the similar length of the face 18, as shown in Fig. 2, thereby retaining the lip entirely below the top plane of the shoe. The portion 23 is in the form of a vertical extension having a laterally extending recess or groove 26, said groove approximately corresponding in vertical width and opposing the face 15 of the shoe, the ortion of the extension below the groove being beveled to complementally fit the inclined face 14. The portion of the extension above the groove is of su'flicien t thickness to provide suflicient support to the fastening nin 27 which is adapted to extend through the groove as presently described. The groove 2G may be formed wedge-shaped, or, if desired, may have its walls extend in parallel planes 3 in either case the pin 27 is formed to correspond with the configuration of the groove. The length of the extension 23 is equal to the length of the distance between the opposing shoulders formed on the outer face of the too portion of the shoe. The extension is shown as of less length than the length of the'lip; the amount of difforence in these lengths does not affect thc operation of the shoe, and it will be understood. that this difference may be more or less than that shown in the drawings.

1n placing the toe call: in position, the call: is slipped under the toe of the shoe and the complemental faces of the shoe and lip brought into contact. The calk is then operated to bring the upper face of the calk into contact with the bottom face of the shoe, during which operation the inclined faces of the extension and shoe cooperate to roperly position the lip in contact with the s ioe; this positioning p acing the lower plane of the groove 26 in alinement with the upper face of lugs 16. The pin 27 is now inserted through the groove and locked in position by having its thinner end (if the pin be wedge-shaped) bent into the recess of the shoe formed during the upsetting of the metal of the latter to form the portion 12. In case the pin is equal in size from end to end, both ends of thepin are bent into the recesses, this latter operation being provided for the purpose of preventing the pin from being withdrawn.

By this construction it will be seen that there is no portion of the call: which projects above the plane of the top of the shoe with the exception of the extension portion 23 and this is located in a position where contact is not made with the periphery of the foot of the animal; that the configuration of the calk and shoe is such that the operation of moving the calli to its seat properly Jositions it and at the saine time tightens the fastening portion of the call; on to the shoe, and that in placing the calli in position no )ortion thereof is required to pass into the p ane of the top of the shoe or into contact with the foot of the animal; that the calk is held against lateral displacement by reason of the shoulders formed on the front as well as the back of the toe of the shoe, this feature also preventing any liability of rocking laterally under excessive strain in use; that the calli is held against vertical movement relative to the shoe by reason of the inclined faces of the lip and shoe and the placing of the pin across the top of the lugs 1 6 and that the pressure placed on the cali; in use causes the parts to more firmly engage by vreason of the inclined faces i lof the main calk portion, which may be of desired form, and the securing portion, the latter being provided mainly by the vertically-extending lips 29 op osing each other and having inner incliner faces formed to com lementally engage the inclined faces of the eel of the shoe. The upper face of the calk portion is formed with a groove or recess 30. The heel call; is secured in position by a -pin 3l.

To secure the heel calk in position, the pin 31 is first placed in position in contact with the bottom face of the shoe with the head 32 extendingwithin the recess 18, thereby roviding a projecting rib for the bottom of1D the shoe over which the calk is slipped, the pin (or rib) lying within the recess 30, the groove and pin having complemental configuration to permit of such slipping movement. When the calk has been slipped into position where the inclined faces of the lips and shoe en age, a tap of a hammer on the end of the ca k (if a tighter fit is desired) can be given, after which the exposed end of the in is bent downward as at 33, thereby locking the calk against movement in a direction to withdraw it, movement in the o posite direction being prevented by the we ge-shape form of the shoe and calli-lips.

While the lips 29 are shown as extending to the plane of the top of the shoe, it will be obvious that by decreasingv the vertical length of the inclined faces of these lips, the plane of the top of the shoe may be permanently located above that of the calk without materially affecting the engagement of the calk and shoe.

To disengage the heel calks it is necessary only to straighten theV pin 31, whereupon the calk can be slipped off, the tap of a hammer releasing any tendency of the calk to bind.

By reason of the manner of mounting the heel calks, it will be readily understood that the position of the calks on the foot of the animal can be had with accuracy, the distance between the inclined faces of the lips 29 determining what vportion of the heel of the shoe will be occupied by the calli. And it will be readily understood that each of the calks can be placed in position, or removed, Without affecting the position of the shoe on the animal, while the fact that all portions of the shoe which cooperate with the calks to retain the latter in position are protected from wear by the calks, permits of theuse of the shoe for a greater length of time, the -wear of the intermediate portions of the shoe, if there be any Wear, not affecting the retaining portion of the calksor shoe.

Obvious additional advantages, such as the ease With which the calks may be inserted or removed, the durability of the shoe, the positive locking of the calls, and low cost of manufacture are ynot set forth in greater detail.

While I have described :ai-preferred form of construction of parts, it is to be understood that modifications may be made therein as by changes in the proportion of parts, etc., and I desire it to be understood that I may make such changes and modifications therein as may fall within the spirit and scope of the invention as expressed in the accompanying claims. y

Having now described my invention, what I claim as new is:
