MACHINE FGR ROLLING CARRIAGE TOP IRONS.

SPECIFICATION forming part of Letters Patent No. 372,711, dated November 8, 1887.

(No model.)

5.0 aZZ whom, it may concern.-

Be it known that I, FRANK. SCHREIDT, of Mansfield, county of Richland, and State of Ohio, have invented a new and useful Improvewent in Machines for Rolling Carriage-Top Irons, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to a novel construction of the rolls or roller-dies for giving to the iron bars used for carriagetop bows, and other irons, the desired form and the desired uniformity in size, and to the means employed, in conncction with said rolls, for controlling or guiding and stopping the irons to be operated upon, as hereinafter described and claimed.

In the accompanyingdrawings, Figure lrepresents a side or front elevation of so much of a rolling-machine as is necessary to show my improvements; Fig. 2, a plan view of the same; and Fig. 3, avertical transverse section taken on the line as 00, Fig. 1.

A, A, A, and A. indicate stout upright-s secured, in practice, to any suitable frame or base, and provided in their upper ends with bearings for a shaft or shafts, B B, having a band or driving wheel or wheels, 0 and C, socured to them, through which motion is im- 0 parted to said shaft or shafts in any suitable manner.

The machine will be described as though the shaft B B were divided and each part driven independently of the other; but it will be apparent that it might be made continuous, in which case only a single driving or band wheel would be required. On the shaft B is secured a roll, D, having one or more grooves, d, in its periphery, and upon a short shaft, B mounted and adjustable in suitable bearing-blocks in the standards A and A, is a second roll, D, having a similar groove or grooves, d, in its periphery, the counterpart of that in roll D, and forming in connection therewith the die in which the bar to be operated upon is rolled and reduced to the desired size. The shaft B has upon it, adjacent to the roll 1), a spurgear, E, in mesh with a similar gear, E, on shaft B for imparting to the latter a rotary 5o movement in the reverse direction to that of shaft 13 and its roll, causing the contiguous portions of the two rolls acting on the metal to move together.

The periphery of the roll D at the sides of and adjacent to the groove (Z is beveled at (l to give to the edges of the groove a sharpened or cutting form or edge, and the roll D may be similarly formed; but I prefer to reduce the diameter of the latter abruptly through a vertical shoulder, or one perpendicular to the shaft of said roll at the sides of the groove (1, thereby giving sharp cutting-edges to the roll D at the sides of the groove, which serve, in connection with the edges of roll D, to remove from theiron operated upon any surplus metal which cannot be compressed into the die or grooves.

To the standards A and A, in front of the groove formed between the contiguous faces of the rolls D and D, is secured a stout guide and stop bar, F, provided directly in front of said groove with a slot or perforation, f, conforming in shape, preferably, to that of the grooves or die in the rolls, and of sufficient size to permit the bar of iron to be fed through it, and guided thereby to said rolls. Said bar F serves also to prevent the passage of the knuckle or joint on the end of the iron operated upon, and so serves as a stop for regulating the portion to be left adjacent to such knuckle in the squared or unrolled form of the bar.

Upon the shaft 13 and a short shaft mounted in bearings in standards A and A are arranged rolls G and G, geared together and operating in a manner similar to rolls 1) and D, and providcd with grooves g g and g g" in their peripheries, as shown. The grooves in rolls G and G are not provided with cutting-edges, for the reason that the surplus metal is sup- 9o posed to have been removed by the passage of the bars between the rolls D and D for that purpose; but the grooves g g are by preferen ce formed edgewise in the faces of the rolls, and serve to remove and roll into the body of 5 the iron any tin or fins formed or left upon it by the action of the cutting-rolls D and D, while the grooves g and g are formed fiatwise in the rolls and of the exact form and size which it is desired that the rolled portion of I00 the iron shall assume when completed. A perforated guide and stop bar, F, similar to lar tube in rear of rolls D and D.

I is a pipe with branches for supplying water to the rolls for keeping them cool.

Aside from the features of construction and arrangement of parts hereinabove specifically described, the machine in its organization and construction may be similar to that described in another application filed by me of even date herewith.

Having now described my invention, I claim as new- 1. In a machine for rolling carriage-top and similar irons, the rolls between and in grooves in which the iron is rolled into the desired shape, provided with cutting-edges adjacent to the grooves in their peripheries forremoving surplus metal from the bars operated upon in the process of rolling the same, substantially as described.

2. The combination, with the rolls having the peripheral grooves and cutting-edges, of the perforated guide-bar through which the iron is fed to the rolls, substantially as described.

3. The combination, with the rolls having the forming-grooves and cutting edge or edges, of the finishing-rolls for operating on the irons after they have been subjected to the reducing or cutting rolls, substantially as described.

4. The combination, with the grooved cutting and reducing rolls, of the perforated guide-bar through which the irons are fed to the rolls, and the receiving-tubes for receiving the irons from the rolls and straightening for preventing the curling of the same, said guide and receiving tubes being arranged to adapt the irons to be passed transversely between the rolls, substantially as described.

5. The combination of the cutting and reducing rolls, the finishing-rolls, and the perforated guide and receiving tubes, arranged and operating substantially as described.

In testimony whereof I have hereunto set my hand this 7th day of January, A. D. 1886.
