The object of this invention is to furnish a cheap, durable, and eflicient calk, easily adjustable, which shall prove a protection against slipping, and shall bear entirely on the shoe, not Injure the hoof, or cause discomfort to the horse when shod according to the method proposed. The inventor claims that it will not cost as much as the blacksmith's charge for calking a shoe as now performed ; that it will keep sharp and will prove a great saving of time, as every driver can adjust his own calks as he needs them. The engraving illustrates the appearance of this calk when fastened to the shoe or the foot of a horse, and also gives a sectional detail showing the construction of the calk and the mode of fastening it to the shoe. The shoe proper is of the ordinary form, minus the toe calk, in the place of which two of the adjustable calks are used, one on each side of the toe. The calk is provided with two clasps, as shown in the sectional detail, one of which passes over the inner side of the shoe, and clasps down upon the top of the shoe on the inner side. The other passes upward across the outside of the shoe, and rests not only against the shoe but the outer side of the hoof. It is held in this position by a screw passing obliquely down-ward through the outer clasp till its point reaches and rests upon the top of the shoe. The calk is made of material best adapted to withstan-d wear, and of a form best calculated to give a firm hold ?? the foot in traveling. This improvement "was patented through the Scientific American Patent Agency, May 35, 1869, by Rev. Kingston Gtoddard, D. D., of Richmond, Richmond county, Staten Island, N. Y., who may be addressed for State, county, or shop rights
