The nature of my invention consists- First, in making cylindrical metallic rolls,.with a slight groove in the corner of lthat collar, -which projects' into the main groove of the 'opposite roll, and forms one face of the bar, for the purpose of forming a bead, or fillet along one edge of the horseshoe-bar;

Second, in the construction and'arrangement, ou one of a pair of horseshoe-rolls, of a malleable-iron ring, for rolling the bevel required in horseshoe-blanks;

Third, in the construction and arrangement of a malleable-iron creaser and malleable-iron die-rings, in connection with a pair of horseshoe-rolls;

Fourth, an adjustable guide-rest onthe feeding side` of the rolls, in combination -with a bevel-faced die or roll for rolling horseshoe-blank ba1s;and

Fifth,. in the constructiouof a delivering-guide, having a projecting lug which enters into a groove in the rolls,'for preventing the guide from moving laterally while the rolls are in operation..

To enable others skilled in the art tomake and use my invention, I will proceed to describe its construction and mode of operation.

On oneroll, preferably the upper one b,'1 arrange a malleable-iron ring, O, of the form shown in fig. 4, a part of-such ring having a smooth cylindrical face, c, for rolling those parts of the shoe-blank which in the shoe are to be flat or nearly, and the remainder of the working face, of the ring having a bevelled die, c', properly arranged for bevelling the face of the blank at and near those parts which are to form the toe of the shoe.

(the opposite end beingallowd to spread in the-oppositedireeongflnalso make of malleable iron, slip it ouV to 'the roll, and-hold it up by the nut f', as alreadydescribed.,

In the manufacture ofhorseshoes heretofore, cast- Yirgni rolls have been .used with steel creasers. Such rolls are objectionabfe, becausetlie bevel-dies'aniell lars, in reducing the iron harsto blanks of varying width and thickness, are subject to an amount of wear which ordinary rolls do not experience, and in consequence of which theyspeedily become worn. And as each size horseshoe-blank requires to be of a particular dimensiom'the rolls cannot be'turned down -so as to be again useful in making horseshoes of that' size. Hence, new rolls are frequently required. But by the user-of the malleable-iron rings O' D and collar c, I secure not only greater durability in the working parts, (malleable ironfbeing for such uses more durable than castiron,) but also so make them that the parts so subject to greatest wear shall be removable, so that when the faces of one set of rings are so worn out as to be useless, they can be removed, and new ones put in their places at small cost, and wit-h the loss of .but The old ones, after being refitted, may

blanks.

I also find malleable-iron creasers superior to steel ones, as they are less likely to break; and I find the further advantage, that by making the working faces of malleable iron, I produce smoother and better-in ished work. The rolling is done in the usual way. The die c bevels the upper face of the blank, and the creasers d crease the opposite face at the required points.

I. have sometimes found a diflculty in rolling a full and perfectly-formed bead along the outer edge of the blank, between the creasers d and the adjacent collar e. '.lo secure a bead as full and perfect asis required, I use a device shown in the rolls m fm', which repre- I sent a pair of metallic rolls, having collars n n' and grooves o, of suitable size for 4rolling horseshoe-bars.

One corner of th'ecollar 111 out away slightly, or

cut therein a shoulder groove, or oiiset, s, so that when a bar is passed through a bead, s', g. 3, will be rolled` thereon. At theI same time, if so desired or found necessary, I round up the corners in the bottom 4of the groove o, by llets o'.

' The bar l thus produced is then passed through the .other rolls, c and D, in suclrposition that the bead s rlhe difficulty in the. making of a well formed creasebead exists not only in making horseshoe-blanks by lrolling, but-also in that class of machines where the blankis creased by swaging, and the usefulness-.of a. bar having a bead rolled thereon as described, is equally great, whether the subsequent steps in themanuf'acture of the horseshoe are performed by rolling, swaging, or otherwise. Hence, I claim the manufacture of a. beaded bar, as described, Without regard to themode in which it is workedup into horseshoes.

- The malleable-iron parts hereinbefore referred to are-made in any ofthe ways known in' preparing Inalleable-iron castings.

In rolls such as those described, where the pressure ofthe rolls cornes onthe bar with a varying force at different points iu the bar. it is necessaryto have a fir-mly-xed and accurately-adj usted feeding-guide.

To secure this, I fasten to the housings A, Va guiderest, p, and make it adjustable up anddowu by screws 1', playing in -slots 'r'. To the cross-bar p', I bolt or otherwise securely fasten the guide-box, through which the bars are fed into the rolls.v But a still greater difulty exists in the tendency of the bars to follow the roll. Delivery-guides have been used, which operated close to the surface of the roll, but in horseshoe-rolls, such guides are apt to spring or wabble a little from side to side, till they come in the path of the creasers, when, of' course, the effects are disastrous.

To remedy this evil, I make a groove, c', in the roll by', and then, ou the delivery-guide g, make alug, gv which` projects into the groove e', and, as near as may be, is of the same width.

The guide g rests on an adjustable guide-frame, such as is above described, is notched, as at u, for the creasers d, and its end a works closely to the face o t the .rollb', or of the ring D, so as in all cases to deliver the bar therefronl.y 'lhe lug g prevents the guide g from moving laterally, so that it is held securely to its place.

l What I claim as, my invention, and desire to secure' lby Letters Patent, is-

et. As a step in the-manutcture of horseshoes, rolling a bead, s', along the edge of one face of the bart preparatory to creasing, substantially as described.

The'delivery-guide g, having a lug, g', entering the vgroove e', substantially in the manner and for the purposes set forth.

(i. rlhe combination of the adjustable guide-rests p p' with the malleable-iron die-rings C and D, and the rolls b b', substantially as described.
