TO ALL WHOIWI IT MAY CONCERN:

Be it known' that I, ABRAM B-Ensn, of Pittsburg, in the 'county of Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in Machines for Rolling Horse-Shoe Bars; and I do hereby declare the followingto be a full, clear, and'exact description thereof.

The object of my invention is to roll bars of iron of irregular width and thickness, for the various uses to which such bars are applicable in the arts and manufactures, and the nature of it consists in the construction and arrangement of cylindrical rolls, with properly-shaped grooves or recesses and flanges which grooves, recesses, and flanges are provided with creasers and formerssuch as to give to the bar or blank to be rolled the requisite shape, bevel, and ilare preliminary to its being applied to the uses for V,which it is designed. The machine I am about to describe shows the application of my invention to themanufactnre of horse-shoe blanks, by rolling common or horse-shoe bar iron into bars, or a succession of blanks, of suoli form and shape as, when properly cut and bent, to be made into horse-shoes. Such isone of its most useful applications, though not the only one.

To enable others skilled in the art to make and use my invention, I will' proceed to describe its construction and mode of operation'as applied to rolling horse-shoe blanks, referring for that purpose to the drawings hereto annexed and forming a part of this specification, in whichl Figure l is a front elevation of my improved rolls.

Figure 2 is a cross-section of such rolls, through the line :z: fr, iig. 1.

Figierre 3 is a similarA section of the same, through the line z z, iig. 1.

Figure'4 is a vertical side elevation of that part of the rolls shown in cross-section in fig. 3, -the housing being removed; and

Figure 5 represents a horse-shoe blank, or a section of a bar made up of such blanks as rolled by the machine.

Like letters of reference indicate like parts of each.

a and a are two cylindrical metallic rolls made in any known manner. They are operated on journals of any convenient form, and in housings b of any desirable construction. They receive their motion in the usual way, and are connected by gear-wheels c c. One of the rolls a has a flange, d, of square or rectangular cross- Ysection surrounding it, which plays into a groove, d', in the other roll a. The breadth of such groove d', and

its depth below the outer face of the' flange el, should bc of the size necessary to reduce a common bar of iron to the shape required for a horse-shoe bar, usually about three-quarters of an inch in breadth by three-eighths of an inch deep. Another set of rolls, or as shown in the drawings, the same set a a', have another groove e and flange e fitted with creasers and formers, so that by being passed through them the horse-shoe bar is reduced to a series of blanks of variable width and thickness, but of the required shape.

Horse-shoes, it is well known, have to be creased on the under side and near the outer edge, so as to form a recess for the nail heads. The upper side of a properlylshaped shoe-flares or is bevelled downward and inward, commencing a little forward of the corks, the slope of such flare or bevel increasing from those points forward 'to the toe, and the width of the shoe at the same time usually being correspondingly increased in the same i direction, consequently toV make the creases required in the shoe I make in the bottom of the groove e'suitably'- shaped' projections or creasers t' 1f extending partly around the roll', and each creuser z' of such length and all so arranged thateach alternatel interval o shall be of the length required between the ends of creases at the toe of the shoe, and the other intervals o' shall be equal to the distance between the adjacent ends of the creases of two consecutive blanks. Thus the blanks will be creased at the proper intervals.

In order to flare and bevel the blank as required for the upper face of the shoe, I-make theflange e with projecting former-s s s on its outer face, so arranged as to flare and bevel the successive blanks in the manner required for the shoe, substantially as above` set forth. Such 'formers 's s should taper both in width and depth, each from the middle toward either end, so that the flare may be greatest at the middle of each blank, or in other words, at the toe ofthe shoe. Of course the devices described shouldhe so constructed and arranged that the intervals o between the creasers t' sha-ll, as the rolls a a revolve, come opposite, or nearly so, to the middle of the i'ormers s, and the intervals o opposite the intervals between the ends of such formers s.

The width of the horse-shoe bar should be the width required in the shoe just forward of the corks and` back of the points where the flaring begins, or nearly so. The formers s, of course, while" dating the upper 2 sans face ofthe shoe-blank must necessarily reduceit somewhat in thickness along its inner edge, and consequently increase its width. Such variation of width I provide for by the spring-guidef, Bo placed as readily to allow the bar to be fed intothe groove e, and as the bar increases and decreases in width while passingv'through under the action of the formers s, the spring-guide f is forced back by the bar till the blank at its broadest part fills the groove e', and after the middle of each former s is passed, the former s tapers, the width of the blank becomes less, and the rigidity of the spring-guidef causes it to follow up the bar in its gradually reducing'y width, and hold it in placein the groove e. The bar-is thus rolled intoa series of' consecutive horse-shoe blanks, each properly creased and dared, and of the variable width and thickness required in a horse-shoc,' us shown in fig. 5. l

As a modiiication of the machine described I have-shown a somewhat different form of' roll in figs. L and 3 for accomplishing the same result. g and y are either a prolongation of the rolls a and a', or another set of cylindrical metallic rolls of somewhat similar construction. One ofthe rolls'g has on its cylindrical surface the creascrs i similar in shape, arrangement, and operation to the creas'ers z', above described. Theother, g', has a recess, z, under thc creasers i', and the lower face er print s of such recess L corresponds more or less exactly to the outer face of the iiange e with its Aformera s, and accomplishes the same results in substantially t the same way. As shown in the drawings, the rolls g and g are designed to form one horse-shoe blank at a revolution, while the rolls a a are so fitted as to shape two at each revolution. Guides m are also used, but as I usually shoulder the recess h out of one end of the cylindrical surface of the roll g', I prefer yto regulate Athe width of the blank while being widened and flared by the print s by the use of an upright frictionroller n, whose journals bear against springs sct in the housing b. Such roller l11, may, if so desired, have a ilange,vn, opposite to and of proper width to enter the recess 71, forthe purpose of bearing against the edge of the bar while passing through. The direction (nf-pressure of the roller n o1' the spring-guidesfshould be against the slope of the formers s or the print s. The spring-guidesfmay be attached on either or bo'th sides of the y rolls, so that the rolls may befed whilerevolving in either direction. In either of the ways described I roll a bar or series of horse-shoe blanks of the shape substantially as shown in fig. 5, and needing only to be cut apart and bent ,in order to be ready for market, which may be done by other mechanical appliances adapted to-sueh purposes. As already statcdI apply this mode of rolling to forming or-shaping bars of irregular width or thickness for other purposes to which such bars are applicable, or for which they are useful; hence, what I claim as my invention, and desire to secure by Letters Patent, is

1. A pair of cylindrical metallicrolls, one grooved andthe other flanged, with a projecting creaser or creasers in the bottom of one or more of the grooves,l and one or more projecting formers s on the outer face of the corresponding flanges, in combination with one or more spring-guidesf, all constructed, arranged, and y operating substantially as described.

2. A pair of cylindrical metallic rolls, one having one or more creasers z" on its outer cylindrical surface, and the other shouldered or made with a recess, h, and print s', in 'combination with a vertical friction-roller, n, all constructed, arranged, and operating substantially as and for the purposes above described. In testimony whereof I, the said ABRAM REESE, have hereuntoset my hand in presence of- ABRAM 4REESE.
