IMPROVEMENT I N SLEIGHI-SHOES.

The Schedule referred to in these Letters Patent and makingv part of the same vTo all whom Iit 'mayV concern..-

`,Be it known `that I, T. BENTON TITUs, of Phelps, in the county of Ontario, and-State of New York, have invented a new and useful Improvement iu Sleigh-Shoes; `and I do hereby declare that the following isla full, clear, and exact description thereof', reference being had to the accompanying drawings, making part of this specification, in which- Figure l is an elevation of my invention. IFigure-2 is a plan View. U Figure 3 is an inverted view ofthe cope of the mould, in which I cast my improved shoe. 4 The object and nature of my invention will be understood by reference to the specilication and drawings; and to enable others to` make and use Vthe desarne, I will scribe its construction. In the body of a east-iron sleiglr-slroe, A, figs. 1 and 2, I provide the strips a. of ywrought-iron, steel, or

other suitable metal.

The strips a are sustained in their places, while the molten met-al is being run int-o the mould, by staples f, fig. 1, which are inserted in the sand at the sides, top, or bottom of the mould, as desirable. After the ,cast-ings are removed from the mould, these `staples are cut oil' even with the surface.

It is necessary that the strips or rods a be made in short sections, as shown, since I ind, by experiment, that if long strips of wronght-rnetal are used, they l warp, by expansion, when the molten metal comes in contact with them, and push aside the sanded dies, which are placed in the mould to form the holtholes,

thus rendering the casting defective.

It is also desirable that the stripsv should break joints, or be so arranged that a cross-'section at `any point on the shoe would cnt one or more of the wrought-metal rods, as shown in tig. 3. If'neessarygthese strips may be bent in any desired form, to avoid the bolt-holes in the centre of the shoe.

In narrow shoes, it may be advantageous to employ' thin strips of met-al, placed edgewise, whereby greater vertical strength is obtained, and there is less liability of their' interfering with the bolt-holes.

It is evident, that if the shoe should break at the bolt-holes, or any other point, the wrought-metal strips would hold the parts in place. This shoe has thus the well-known advantages of a cast shoe, and.

the toughness of a wrought-metal one, combined in a Very cheap and eliicieut manner.

What I claim as my invention, and desire to secure by Letters Patent, is

A cast-iron sleigh-shoe, with short sections of.
