Specification of Letters Patent.

Patented June 5, 1906.

Application filed February 28, 1906. Serial No. 303,478,

To all whom it may concern:

Be it known that I, JosEPH O. H. ORAN- MER, a citizen of the United States, residing at Greenville, in the county of Montcalm, State of Michigan, have invented certain new and useful Improvements in Horseshoe- Calks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention has relation to that class of horseshoe-calks that are removable and replaceable for the purpose of sharpening them when they become dull from wear Without taking the shoes off the horses feet, as is now commonly done.

The invention has for its object the provision of means whereby the heel and toe calks may be removed, as above stated, in the easiest, quickest, most desirable, and safest manner and so that they can afterward be replaced and worn as though they were one with other parts of the shoe.

The nature of the invention consists in making the heel and toe calks of steel of quite high carbon content, so that they will be hard and resist wear, but forming the other parts of the shoe of softer metal and making the calks attachable and detachable, as is hereinafter fully described and claimed,

reference being had to the annexed drawings,

forming a which Figure 1 is a side elevation of a horseshoe embodying my improvements. Fig. 2 is a bottom plan view. Fig. 3 is an enlarged detail elevation. Fig. 4 is a detail perspective view of the calk.

Referring now to the drawings, 5 represents a horseshoe of ordinary shape, with the exception that at the toe there are two depending members 6 and 7, that extend transversely of the shoe and in spaced relation, said members, however, converging downwardly and having at their ends the flanges 8 and 9, respectively. The flanges 8 of one member project toward and are in the same plane with the'flanges 9 of the other member, and the mutually-adjacent edges of the corresponding flanges of the two members converge downwardly at the same angle as the facesof the members 6 and 7 proper. A calk 10 is provided for the toe of the shoe part of this specification, in

and is tapered and has such angles and dimensions that it may pass between the flanges 8 and 9 at one end of the depending portions 6 and 7 until it lies between the flanges of both ends and may then be forced downwardly away from the shoe proper, so as to contact with the mutually-adjacent faces of the members 6 and 7 and lie behind the said flanges 8 and 9, as illustrated in Fig. 1 of the drawings. To thus shift the calk downwardly from the shoe proper, a pin 1 1 is driven in between the calk and the under side of the shoe between the members 6 and 7, and to further hold the calk a pin 12 may be passed through corresponding perforations in the members 6 and 7 and through a notch 13, formed transversely through the lower face or bottom of the calk.

From each heel there depend two members 6 and 7, corresponding to the members 6 and 7, above described, and having flanges 8 and 9, corresponding to the flanges of the members 6 and 7, respectively. The calks are first moved inwardly between the flanges, as illustrated in Fig. 3, after which pins 11 are driven between the bases of the calks and the lower faces of the ends of the shoe, so as to force the calks and hold them within the embrace of the flanges 8 and 9. Pins 12 may then be passed through the members 6 and 7 and notches in the bases of the calks corresponding to the notch 13 in the base of the calk 10. It will thus be seen that the calks when in position are held securely and that by removing the pins or wedges removal of the calks is readily accomplished.

I/Vhat I claim is A horseshoe having pairs of depending spaced holding members at its toe and heel portions, each pair of holding members being converged downwardly and having end flanges, the flanges of each holding member extending toward and in the same plane with the corresponding flanges of the other holding member and having their mutually-adj acent edges converged, a tapered calk engaged between each pair of depending holding members and within the embrace of the flanges thereof, and a wedge disposed between the base of each calk and the corresponding face of the shoe, the dimensions of each calk and the spacing of the end flanges of the corresponding holding members being such that, when the wedge is in place, the calk will lie in close contact with the corresponding de- In testimony whereof I aflix my signature pienciingfl members dandhwithin thed embrace in presence of two Witnesses.

0 t e anges, an W en the we e is removed and the calk is shifted into contact JOSEPH CRANMER' 5 with the face of the shoe, it may be drawn Witnesses:
