UNITED STATES PATENT EETCE.
ROLLING-M LL.
SPECIFICATION forming part of Letters Patent No. 260,196, dated June 27, 1882.
Application filed August l2, 1881. (No model.)
To all whom lit may concern:
Bc it known that I, JAMES T. HAsTrNes, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rolling-Mills, of which the following, in connection with the accompanying drawings, is a specification.
In the drawings, Figure-l is a front view of a rolling mill or machine embodying my invention'. Fig. 2 is a side View of the same. Fig. 3 is a vertical section in the plane ot the line x gr of Fig. 2. Fig. 4 is a detail of one ofthe products capable of being made on the said machine. Fig. 5 is a detail or plan view ot' the rollers which may be employed for holding the bar or rod and the blank out therefrom while the forming-rolls are being rotated,.and Fig. 6 is a cross-section in the plane ot the line y y of Fig. 1.
Like letters of reference indicate like parts.
A represents th'e frame of the machine. B B' are rolls or dies journaled in bearings in the frame.
C is the driving-shaft, and D is a pinion thereon.
E E are spur-wheels on the axles of the rolls B B', respectively. l
The wheels E E'are arranged to be engaged and driven by the pinion D when the latter is rotated. By these means the rolls B B', as is obvious, will be rotated in opposite directions. F is a driving-pulley on the shaft C, and G is a driving-belt on the pulleyF. The working faces or perimeters of therolls B B' are so formed that when arranged together or nearly together or when they are tangent to each other, or nearly so, as indicated -in the drawings, a space will be included between them which will correspond to the outline of a vertical central sectional representation of Ithe product to be produced by the rolls; and this space will extend crosswise of the rolls, as indicated in Fig. 6. For example, let it be understood that the rolls B B' are adapted to make the well-known form ot' coupling-pins shown atea, Fig. 4. Then the space at the tangent point of the rolls will correspond to the said pin in form, as shown at a', Fig. 6. ln other words, to adapt the rolls B B' to make 5o the pin a, I sink in the rolls a groove, b, corresponding in depth to the distance the collar b' on the pin extends from the stem or body ofthe pin,and near the groove b, I sink a shallow groove, c, and between this groove and one side of the roll I raise a rib or cutter, c', the part between said cutter or rib and the groove c being so formed as to'make the head of the pin. On the otheredgeoi the rollsIraise the rib or flange d. ot' such shape as to form the tip or end ot' the pin. In order-that the bar or rod from which the pins are to be made may be fed in between the rolls B B', I cut away a small portion of the ribs or cutters c' c', as shown at e e. The flanges d d will serve also as stops to prevent the rods or blanks from being fed in too far. It will now be perceived that if a rod or blank of red-hot iron be fed in between the rolls B B' and there held during the rotation ot the rolls, it will be rotated on its axis as the rolls'move in opposite directions, it being understood that the rolls, after being rotated a little way, begin to pinch the blank, as their diameters increase slightly more and more, until the pins are completed-in other Words, the rolls are slightly cam-shaped or eccentric. The cutters c' c' are also slightly eccentric, being comparatively low at their forward ends, or where they tirst meet the rod or blank, as shown at f f, and higher at their other ends, as shown at f'f'. By this means the parts c' c' operate as cutters or shears and cut o-r pinch off the completed pin from the blankrod. To better insure the rotation of the blank or unfinished pin between the rollsIraise burrs g on a partof thefaceof eachroll. Theremaining or smooth parts of the faces of the rolls will smooth down the roughness on the pin produced bythe said burrs. By the time the pin is finished it drops into a depression, B", extending aeross theface of the lower roll, and, being carried around thereixndrops out as soon as it is in a position to be acted upon by gravity.
It is to be understood that when the blank is fed up to the angcs d d its diameter should be such that no injury will result to the niachine after the grooves b and c have been lled; but it is not essential that the blank should be pushed in until it strikes the flanges d el, as a y ICO H H are plates rigidly attached to the frame A, and the ends of which are far enough apart and so arranged as to allow the blank'rod to be fed into the machine in the manner described. The function of these plates is to hold the blankrod and unfinished pin in place until the rolls have performed their work. Rollers I I may be journaled in these plates, as indicated in Fig. 5.
J is a rest or guide for the blank-rod, but is not absolutely essential, it being understood that the rolls B B', when properly set to receive the rods, will indicate when it is to be fed in.
It will also be perceived that the rolls B B' may be of such diameter as to admit of their being adapted to operate upon two or more blanks before the completion of one revolution. The rolls may also be of such width as to operate upon two or more blanks at the same time that is to say, to cut off and roll more than one pin at each insertion of the blank-rod. Au interspace, a', remains at the place ot' feeding during the rotation ofthe rolls or from the time of feeding until the completion ot' the product. In stating that the rolls B B' are rotated in opposite directions, I have reference to the fact that they move in opposite directions upon the blank or at the place of feeding.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
The combination of the eccentric rolls B and B', having therein the grooves b and c, and the depression B", and provided with the eccentric cutters c c', and the anges d d, the rollers I I grooved to correspond to the rolls B and B', the frame A, and rotating gearing, all adapted and arranged for operation together, substantially asand for the purposes specified.
