SPRING-HEEL ronHonsE ALNID MULE SHOES.

Specification of Letters Patent.

Patented Sept. 23, 1919.

Application filed November 27, 1917, Serial No. 204,191. Renewed March 12, 1919. Serial No. 282,194.

To all wkom it may concern:

Be it known that I, GoRooN H. BURKE, a citizen of the United States of'America, residing at Plymouth, in the county of Grafton, State of New Hampshire, have invented certain Improvements in Spring-Heels for Horse and Mule Shoes, of which the following is a description, reference beinghad to the accompanying drawings, forming a part thereof.

The object of the invention is to provide,

. as an article of manufacture and as an attachment applicable toold and more or less worn or new horseshoes, a device embodying a spring heel and rear calks which may be struck from plate metal, of uniform thickness and may be applied effectively and securely to the shoe, with a minlmum of manipulation, by the ordinary or moderately experienced blacksmith or farrier.

Further objects and advantages of the invention will appear in the course of the following description, the same consisting in a simple and inexpensive construction and arrangement of parts of which a preferred form is illustrated in the drawings, in which- Figure 1 is a bottom plan view of the device as seen when applied to the shoe;

Fig.2 is a top plan View also including the shoe and showing in dotted lines the positions of the forward lateral projections or cars as seen prior to the application of the article to the shoe;

Fig. 3 is a side view of the attachment, also as seen when applied to the shoe; and

Fig. 4 is a plan view of the blank as seen when struck from the plate.

In some respects the device forming the subject-matter of this invention is similar to that set forth in the patent of this applicant, No. 1,170,218, granted Feb. 1, 1916, in that, like the former device it is constructed of a suificiently resilient and resistent spring metal, such as steel or any other metal, and is of substantially U-shape with the cross bar or loop of the U disposed at the heel of the horseshoe (when in use) and with the upwardly extending arms provided with termi nal ears, or inwardly extending projections, which are sufficiently pliable to adapt them to be bent around the inner edges of the sides of the horseshoe to form holding clips, the body portion of the device, springing at a point adjacent to said clips, being deflected from the under surface of the shoe, to permit of a yielding movement of the same toward and from the plane of the shoe as the weight of the animal comes upon or is removed therefrom. 4

In the present construction the device is adapted to be struck from a fiat sheet or plate of metal of uniform thickness to form a blank as illustrated in Fig. 4, whichembodies the general U-shape .as above noted with the loop or cross-bar 10 curved or arched forwardly both at its forward and rearward edges, to lie fairly within the contour of the shoe 11 at the heeL-and the forwardly extending arms 12 follow approximately the curvature of the sides of the shoe and terminate in inwardly projecting cars 13 which are normally in the plane of the body portion. of the device but are adapted tobe bent upwardly and outwardly to the positions shown in Figs. 1 and 2 (in full lines in the latter) toengage the inner edges and upper surfaces of the sides of the shoe. In the construction illustrated the arms of the device may be arranged tounderlie the rearmost nail-holes 1450f the shoe and may be provided with corresponding and registering openings 15 through which the rearmost nails, employed for securing the shoe in place, may be driven, but this is optional and not essentially necessary to the proper securing of the attachment to the shoe, for the reason that the length of the arms of the attachment is regulated so as to engage the shoe at the point of greatest width thereof.- Hence displacement forwardly or rearwardly is prevented by the curvature of the inner edges of the sides of the shoe in front and in rear of the points of engagement of the clips. The portions of the attachment immediately adjacent to the clips, shown at 16, lie snugly in contact with the under surface of the shoe, and in rear of this clip, to-wit, at the point indi cated 17, the arms of the attachment are slightly deflected downwardly to cause a divergence of the body portion from the plane of the under surface of the shoe, this divergence progressing rearwardly.

Also forming a part of the blank thereof are outwardly extending ears 18 formed integral with the U-shaped body portion of the attachment and substantially as continuations of the loop or cross-bar 10 of the U, and which are adapted to be bent downwardly, as indicated in Figs. 1 and 3, to form heel calks, which thus take the place tachment is applied to a wom'0r 01d horssvshoe,'the said supplemental callgs supply the deficiency due to the wearing away of calks of the "ordinary calks formed upon or at tached to the horseshoe, and when'the atwhich may ordinarily have been formed'on the shoe, and thus restore :the efficiency of the shoe in that respect, while adding the advantage of the spring-heel otherwisei i It is; obvious that the device embodying the principles and construction described can be constructed. at a comparatively negligible cost outside of that of the metalitself,

' ,in that it is adaptedto be,f0rmed,1practically ready for application'to'the shoe, by a single stroke of the die. The only addi- V v tional manipulation is-that-incident to bending the calk members, this canbe done .at

the :same time that the blank is formed, should it be found desirableto follow that course; The advantage in deferring this operationuntil the attachmentv is appliedto the shoe,-just as the bendingof the forward 7 ears is deferred .until it is necessaryito-make claimed is: w

application, is that itpermits of thestackxlng and packing of theattachments in c0mpact form so as #to occupy the :minimu space in storage-"and shipment. 7 Havin described the-invention whatis 1. As an article of manufacture; a springheel' attachment for horseshoes" of any type,
