MACHINE FOR ROLLING SHEET METAL.
PECIFIGATION forming part of Letters Patent No. 515,402, dated February 27, 1894; Application filed December 12, 1891. Serial No. 414,775. (No modeh) 'and arrangement of parts herein described,
substantially as shown in the accompanying drawings, and pointed out in the claims.
In the drawings: Figure 1, is a side elevation of the machine. Fig. 2, is a longitudinal section of the same. Fig. 3, is an enlarged detail showingthe tension device and means for securing the same. Fig. 4, is an illustrative diagram of a sheet of metal, the dotted lines showing the directionof the flow of the metal during the different stages of the operation.
- In the drawings, the letters A A designate the straightening rolls. These rolls are mounted in the frame X between the uprights X on the sides of which are guides to control the movement of the journal boxesA.
. The movement or adjustment of the journal layer of rubber F.
boxes is accomplished by thescrews B on the ends of which the journal boxes rest. These screws B engage threads in the bottom side rails andin the top side rails of the frame. The top side rails are composed of a number of contiguous sections or plates 0, and each of these plates or sections has upturned ends over which fitcaps D. The cap D is secured in place by means of the screws E which are driven into threaded holes in the uprights X and pass loosely between the adjoining plates 0. Itis by means of this mounting that I am permitted to introduce a single tension device at the junction of the plates which in the drawings is shown as a This rubber I insert between the turned-up ends of the plates 0 and the caps D. By this rubber being interposed between the plates 0, to which the upper roll' A is connected by means of the screw B and the caps D, which hold them down in place, any unexpected strain will be 7 taken up and the machine not become jammed or broken. It will also be seen that in constructing one of the side rails of contiguous sections and placing a single tension device to act simultaneously on the adjacent ends .of the section, besides effecting a large saving in the cost of apparatus, one of the main advantages resides in the fact that two pairs of rolls may be adjusted or removed by the manipulation of a single adjusting device.
The mountings I have just described are in the sides of the frame and receive the ends of the roll A, at which points I am permitted, by the construction, to obtain the greatest pressure on the sheets of metal, there being no chance to spring here as in the center. This arrangement places the stretching points on the edges of the sheets and causes the excess of drawing to take place there, as is shown in Fig. 4, of the drawings, in which the dotted lines indicate the lines of draft. To obtain a hold on the sheets the alternating rolls are raised and lowered, increasing the frictional hold. To stretch the metal the succeeding rolls are given a gradually increased speed from the end where the sheets are introduced. This I accomplish by any of the well-known means. As shown in the drawings, the pairs of rolls are connected by the interposed gears G which are held in position by means of the bars or straps H, the bars being loosely connected to the shafts of the adjoining pairs of rolls. By this way of coupling the gears I am permitted to adjust the rolls independently, the interposed gears G being constantly maintained in their position by the straps H.
Having thus described the invention, what I claim is 1. In a metal rolling machine, the combina tion of a frame X, a series of pairs of reducing rolls in said frame, a rail of the aforesaid frame made in contiguous sect-ions 0, each section supporting a journal box of one of the rolls of each pair, and a single tension device placed at the junction of the sections constructed-to act simultaneously on the adja- 10 ing ends of the sections, cushion F between the cap D and the adjacent ends of the sections, and screw Efor securing the cap in place, substantially as shown and described.
In testimony whereof I have hereunto set my hand this 3d day of December, 1891.
