MACHINE FOR ROLLlNG CARRIAGE=TOP IRONS.

SPECIFICATION forming part of Letters Patent No. 373,613, dated November 22, 1887.

(No model.)

To aZZ whom it hwy concern:

Be it known that I, FRANK SCHREIDT, of Mansfield, county of Richland, and State of Ohio, have invented a new and useful Improvement 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 rolling-machines for rolling carriage-top bow and other irons, and will be fully understood from thefollowingdescription and claims.

In the accompanying drawings, Figure 1 represents a rolling-machine in side elevation embracing my improvements; Fig. 2, a "ertical transverse section through the same on the line was, Fig. 1. Fig. 3 is aside elevation, enlarged, of the grooved and fluted rolls. Fig. 4, is a verticaltransversesection through said rolls; Fig. 5, a perspective view and a transverse section through one of the carriage-irons after it has been subjected to the action of the rolls.

A represents a base-plate or frame of any suitable construction, upon which two strong uprights, B and B, are rigidly secured, connected by bars b I), and having vertical slots, the vertical side walls of which have suitable ribs or ways, I) b, formed on them, on which are mounted sliding blocks 0, O, 0 and 0 having bearings for the shafts or journals of the rolls D, D, and D said bearing-blocks being made adjustable on the ways b b by means of set-screws b to compensate for wear and regulate the pressure of the rolls. On the shafts, at the ends of the rollers and between the latter and the blocks 0 O, &c., are collars or blocks E, made adjustable endwise of the shafts by means of screws 6 e, for adjusting the rolls endwise and bringing them into proper working relation one with the other. The shaft of the central roll, D, is extended beyond the supporting-standard B at one end, and has secured to it a spur-gear, Fiwhich engages and is driven by means of a pinion, F, fast on a shaft, F, to which motion is imparted in any suitable manner. The shafts of all the rolls extend through the standard B and have interrneshing spur-gears F, F*, and F on their the arrows. The several rolls have each a longitudinal groove formed in it (indicated at g,

g, and g and extending through the portion thereofhaving peripheral grooves, but leaving ungrooved opposing portions which form rolling-surfaces between the adjacent rolls. The rolls D and D have formed upon them, between one end thereof and the center of their length, a series of grooves, h h, and extending 6o thence to near the other ends of the rolls D and D", the grooves in D being the counterpart of and operating in connection with those opposite them in the roll D, those in the other end of D corresponding to those in the roll'D", and all extending around the rolls and terminating in the longitudinal groove therein.

The longitudinal grooves g g g serve as guides or gages for the introduction between the rolls of the ends of the bars or irons I to be operated upon, whether before or after the knuckles t have been formed thereon, and to leaveaportion thereof adjacent to said knuckle end unrolled or square at i, as shown in Fig. 5. The grooves hand h are preferably made flatwise in the adjacent faces of the rollers,as serving to more readily free or give clearance to the bars operated upon, and are used (those at h) for bringing the rods into approximately the desired form, and afterward the bars are passed back between the rolls D and D" through the grooves or dies h, for still further reducing the metal and giving it the desired shape, which is preferably of the form substantially as indicated in Fig. 5, though the grooves may beef different forms for rolling the irons into any desired form. At h a single pair of grooves is shown (others may be added, if desired) for passing the irons through, set on edge instead of flatwise, and these may be used for the final 9o operation for removing or rolling out any surplus metal left after the irons have passed through the forming grooves or dies h and h, but for this last operation I prefer to employ rollers of a different construction, described in 5 another application of even date herewith.

\Vhere the knucklcsi have been formed upon the bars or rods I prior to rolling them, gageplates, having scollops j formed in them to match the rounded end of the knuckles, may roe be secured within the grooves, as shown at J, Fig. 3, in the groove 9 of the roller D.

The direction of the movement of the irons in being operated upon is indicated in Fig. 2, it being in one direction between the middle and lower roller for the first operation described, and in the reverse direction between the middle and upper rollers for the second operation. K is a shelf or table upon which the irons fall or are deposited after the first operation, and upon which they may be straightened out by the attendant prior to passing them back in the second operation.

,L is a water-supply pipe, and Z 1 adjustable branches thereof, for supplying water in any desired quantity to the operating portions of the roller-surfaces for preventing undue heating of the same. The pipe L is connected with a tank or other source of water-supply and is provided with a suitable means for regulating the flow of the water, as indicated.

The form of the grooves g, g, and 9 will of course be such as to adapt it to the knuckle or other protuberance on theirons to be operated upon.

Having now described my invention, I claim asnew- 1. In a machine for rolling carriage-top and other irons, the longitudinally-grooved rolls provided with the peripheral rolling-surfaces and intermediate peripheral grooves of the required form terminating in a longitudinal groove or grooves adapted to form gages for the introduction of the irons to be operated upon, substantially as described.

2; The combination, in a machine for rolling carriage-irons, of the rolls D, D, and D, having rolling-surfaces g and grooves g, g,and g", in which said peripheral grooves terminate,

arranged and operating substantially as deminatingin longitudinal grooves g, g, and g,

arranged and operating as described.

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

FRANK SOHREIDT.
