:"JPECIFICATION forming part of Letters Patent No. 320,531, dated June 23, 1885.
Application filed August '7, 1884. (No model.)
To all whom it 'may concern:
Be it known that we, NAPOLEON BEAURE- GARD and GEORGE J. WrinnLooK, both of San Francisco, State of California, have in 5 vented a new and Improved Round-Metal- Bar Straightener, of which the following is a specification.
The invention relates to th ose machines used in rolling-mills and machine-works for smooth- IO ing and straightening round-metal bars,either immediately after they pass from the formingrollers and while they are still hot, or at any time afterward when they are cold.
The invention consists in a combination of 1 parts by which the bars are slowly fed in a longitudinal direction between three rollers, the two lower ones being simultaneously revolved in the same direction by suitable mechanism, and the upper one revolving independzo ently by the action of the bar passing through. The object of the invention is to expedite the operation of straightening the bar and smoothing its surface, and to provide means for giving the bar a more perfect and mer- 2 3 charitable finish than heretofore obtained.
In the accompanying drawings, Figure 1 is a side elevation of my machine. Fig. 2 is a view of the feeding end. Fig. 3 is a view of the end from which the machine is driven. Fig. 4 is an end view of the bracket of the feed mechanism. Fig. 5 is a sectional view of one of the boxes which supports the horizontal shaft, and Fig. 6 is a diagram illustrating the rollers when all are set askew to the axial 5 line of the bar to accelerate the feeding of the bar through the rollers.
In all the figures like letters of reference indicate like parts. i
A A A are three rollers, of, say, twelve 40 inches diameter and five feet long, with journals which rest in the boxes B, carried in the housings O G. The boxes for the lower rollers may be stationary or adjustable as to height and spread to set the rollers at any de- 5 gree of angularity (within limits both verti-' cally and horizontally) with the axial line of the bar which passes through to be straightened-that is to say, each roller may be slanted both vertically and horizontally. The up per roller, however, must be adjustable vertically to accommodate different sizes of the bars, and may be adjusted horizontally to set it obliquely with the axial line of the bar.
This setting of the rollers obliquely or aslzew is for the purpose of accelerating the feeding of the bars through the rollers.
D D are frames fitted in the housings, in which the upper boxes are adjusted sidewise. These frames are raised and lowered simultaneously when the height of the upper roller is adjusted. The frames are each suspended from cross-bars E E by the rods F F F F, the cross-bars being suspended from the short ends of the weighted levers G, which have their fulcrums at H, supported on a crossbeam of the building in which the machine is erected.
I I are strong screws,which pass through the cap ofthe housing and hear at their points on the top of the frames D D to prevent them rising by the action of the counter-balances beyond the point to which the screws will permit. The upper ends of these screws are fitted with bevel-gears J J. Upon these rest boxes K K, fitted in such a manner as to let the wheel revolve without moving the box. As shown in Fig. 5,the bottom of the box has a circular rim fitting a recess in the plate of the gear. Over the edge of this rim is overlapped an annular plate, which is bolted fast to the gear. In this way the box is held, but the gear is free to revolve.
The shaft L rests in the boxes K K, and is fitted with the bevel-pinions M M. These engage with the gears J J, and on the end of the shaft is the handwheel N to turn it by. \Vhen this hand-wheel is turned in one direction, the screws I I move down and press upon the frames D D, and bring the top roller in closer relation with the lower ones. Vhen the hand wheel is turned in the opposite direction, the screws rise and the counter-balances lift the upper roller away from the lower ones.
0 is the feedroller, which draws the bar for ward to pass it between the main rollers. It 5 is supported on the end of the shaft P, upon which it has a slight lateral play to accommodate any variation that may occur in the adjustment of the lower rollers; also, to provide for any sudden bends in or protuberances 011 I00 the bar, tending to throw the roller to one side or the other. There are springs Q Q on each side to maintain the roller in its normal position when the side strain is removed.
The shaft P is carried in the bearings R R, which are cast 011 the bracket S. On the end of this shaft is a gear-wheel, T, which engages with the pinion U, carried on the shaft V. This shaft is driven from any source of power by a rope or belt passing over the pulley V.
WV is a roller resting on top of the bar. It is carried on the rounded end of the swinging lever X, which has its fulcrum at w, and is connected with the nut Y on the screw Z. This screw bears at its point in the bearing R, and when revolved by the hand-wheel Z vibrates the lever X up or down, either to press the roller Vt on the bar or to release the bar from such pressure, as the case may be.
The bracket S is held and supported on a single fulcrumbolt, a, so that whatever sized iron within the capacity of the machine is passed through, the feed-roller will swing up or down to suit, and with it the holding-down roller on top.
The upper roller is adjusted obliquely with relation to the lower ones by fastening a screw, b, to one side of each of the boxes carrying it, the screws having a joint at cl.
On the end of the screws are miter-gears, which engage with others on the ends of a connecting-shaft, e, which has a handwheel, f, upon it, and is borne in the bracket-bearings g g bolted to the main frame. WVhen the shaft is turned by the hand-wheel, one box is drawn forward and the other pushed back, and thus the roller is set at any desired angle.
The lower rollers are set obliquely by putting thin shims under the boxes at one end and turning back the side screws, h, which bear their points against the boxes of the other end.
The matter of setting the full set of rollers will depend upon the desired speed of the feed, the greater the speed the greater the angularity, and vice versa. If the rollers be all set parallel, then the operation of the roller wheel, Z, which engages with the pinion m on the counter-shaft a, on which the drivingpulley 0 is placed. 19 is a fly-wheel, and q are bearings supporting the shaft.
The operation is as follows: For the smallersized bars-say below four inches diameter all the rollers are set parallel, and the handwheel N is moved until the rollers are set the I thorough manner, alittle water being trickled on the bar as it enters between the rollers. If 'the bars be of larger size than four inches the rollers may be set obliquely with relation to each other, and they will be fed through without other feeding device.
What we claim as our invention is- 1. In a bar-straightening machine, the combination of the rollers A A A, housings G 0, boxes B B, frames D, and mechanism, substantially as described, for adjusting the upper roller, both horizontally and vertically, with relation to the lower ones, as and for the purpose described.
2. In a bar-straightening machine, the combination of the rollers A A A, housings O 0, boxes B B, and mechanism, substantially as described, for adjusting each roller to set obliquely with relation to the others to effect a feeding motion to the bar passing between them, as and for the purpose described.
3. In a bar-straightening machine, in combination with the straightening rollers, the feeding device, herein described, consisting of the roller 0, shaft P with its revolving mechanism, roller WV, lever X, nut Y, screw Z, and bracket S, supported on fulcrum-bolt a, substantially as described.
4. A bar-straightening machine, consisting of three rollers, A A A, supported in suitable frames, 0 O, spur-gears i t on lower rollers, simultaneously driven, frames D for boxes of upper roller, counter-balances, substantially as shown, attached to frames D D, and dcpressing-screws I I, with their actuating machinery, as and for the purpose described.
5. In a bar straightening machine, as a means of adjusting the upper roller to accommodate various-sized bars, the combination, with said roller, of the sliding frames D, suitably held and guided in the housings O O, and carrying the boxes for journals of the roller, counter-balances E F G H, as shown, screws I I, gears J and M, boxes K, shaft L, and handwheel N, arranged and operating, substantially as described.
