CHARLES L. HUSTON, OF COATESVILLE, PENNSYLVANIA.
PLATE-STRAIGHTENING MACHINE.
SPECIFICATION forming part of Letters Patent No. 712,300, dated October 28,1902.
Application filed March 22, 1901.
To all whom it may concern:
Be it known that 1, CHARLES L. HUSTON, a citizen of the United States, and a resident of Ooatesville, Pennsylvania, have invented certain Improvements in Plate-Straightening Machines, of which the following is a specification.
My invention relates to certain improvements in plate-straightening machines.
The main object of my invention is to so construct the machine that the upper rolls can be moved away from the lower rolls to leave an unobstructed passage for the plates in the process of rolling, so that the machine can be placed in line with the rolling-mill and the lower rolls can be used as a part or continuation of the roller-table of the mill and after the last pass the upper rolls can be shifted into position and the plate passed between the upper and lower rolls for the purpose of straighteningthe same.
My invention'also relates to details, which will be fully described hereinafter.
In the accompanying drawings, Figure 1 is a plan view of my improved plate-straightening machine, showing the upper rolls directly above the lower rolls. Fig. 2 is a longitudinal sectional'view on the line 2 2, Fig. 1. Fig. 3 is a longitudinal sectional View, similar to Fig. 2, with the upper rolls shifted. Fig. 4 is a sectional view on the line 4. 4, Fig. 1; and Fig. 5 is a view similar to Fig. 4. with the upper rolls removed.
A A are the housings of the machine.
B B are thelongitudinal rails, extending from end to end of the machine and acting not only as braces for the frames and housings, but also as guides upon which the movable frame D-slides.
A is a pedestal or support for the outer ends of the rails B B and driving-shaft.
E E are the lower rolls of the plate-straightening machine, and F F are the upper rolls. It will be noticed that the trunnions of the lower rolls E are mounted in boxes at a in the fixed frames or housings A, and the trunnion e of the center roll in the present instance extends in the form of ashaft to the pedestal A, in which is a bearing a, for said shaft. On this shaft is a gear-wheel e, which meshes with a pinion c on the shaft of an electric Serial No. 52,379. (No model.)
shaft may be geared or belted to a drivingshaft driven in any suitable manner.
The lower rolls E are geared together by a train of gears e2 6 the gears 6 being on the trunnions of the rolls E, while the gears e are on shafts 6 mounted in bearings in one of the housings A and a pedestal A as clearly shown in the drawings.
The. trunnions of the rolls F are mounted in vertically-adjustable slides G G, arranged to travel in the side members D of the, frame D. These side members are connected together by longitudinal members D in the form of I-beams' in the present instance, so that the frame D is perfectly rigid. The side members Dextend down to and rest upon the rails B, as clearly shown in Fig. 4, and
have slide-blocks d d. The side members D underlap the head I) of each rail, so that the frame is held rigidly to the rails B B and when adjusted above therolls E is fixed, so that there will be no lost motion when the plate is passed between the upper and lower housingsA A under the rolls E is a hydraulic 7 cylinder H, closed at one end by a head h and at the other end by a head 71., provided with a stuffing-box 71 Passing through the stuffing-box is apiston-rodl, having a piston I at its opposite end. This piston may be made in any manner common to hydraulic mechanism.
The'rod I is connected to a cross-bar D secured by brackets D to one of the side members D of the frame D, as clearly shown in Figs. land 2, so that if,'for instance, the frame D is in the position shown in Fig. 2, directly above therolls E, and it is wished to shift the frame to the position shown in Fig. 3, then fluid under pressure is admitted to the cylinder H through a pipe 41, and the piston will be forced to the opposite end of the cylinder, carrying with it the frame D and shifting the frame to'the position shown in Fig. 3. If it is wished to shift the frame from the position shown in Fig. 3 to that shown in Fig. 2, then the fluid is admitted to the opposite end of the cylinder through the pipe 71.
I have shown in the drawings means for raising and lowering the slides G to adjust the rolls F in respect to the rolls E. Projecting upward from the slides G are fixed screws J J, which extend through hearings in the side members D of the frame D and through a cross-bar j, supported by studs j, and on each screw is a threaded pinionj which engages the thread of the screw. The teeth of each pinion mesh with the gear-wheel on a stud K. On this stud is a worm-wheel 7a, which meshes wit-h a worm m on a shaft M, extending from one set of adjusting means to the other. On the shaft M is a gear-wheel m, which meshes with a pinion n on the shaft of an electric motor N, mounted on cross-bars d on the frame D. The shaftM is also provided with a hand-wheel m by which it can be turned independently of the motor when it is desired to adjust the slides G by hand.
the frame and guiding a plate should it by ac- I for driving said shaft, said central roll being cident be moved out of its usual course.
In the present instance on each side of the straightening-machine are the rolls SS, form- 5 ing part of the table of the rolling-mill, as my invention can be used in connection With a 1 rolling-mill and the machine can be set in the table at one side of the mill, so that during the process of rolling the frame D and its rolls can be shifted clear of the lower rolls, as in Fig. 3, and the lower rolls will then act with the rolls S of the table of the universal mill to support the plate as it is moved back and forth between the rolls of the mill, and after 1 the last pass the frame D can be moved in position directly over the lower rolls, so that the plate can be immediately passed through the straightening-machine and straightened on its way to the shears.
In some instances the lower rolls may be driven by the same mechanism that drives the rollers of the table of the rolling-mill, and other means may be used for moving the upper rolls away from the lower rolls without departing from my invention.
While I have shown the shaft e as a continuation of one of the trunnions of the cenlower rolls or to one side of the same, substantially as described.
2. The combination in a plate-straightening machine, of the housings, a series of lower horizontal rolls mounted in said housings, means for driving said rolls, a frame mounted above said rolls, a series of upper horizontal rolls carried by said frame, and means for moving said frame so as to shift the upper rolls either to a position above the lower rolls or to one side of the same, substantially as described.
3. Thecombinationinaplate-straightening machine, of the housings, a series of lower horizontal rolls mounted in said housings, means for driving said lower rolls, rails, a frame mounted on said rails, upper rolls carried by said frame, a hydraulic cylinder, a piston therein, a piston-rod, said piston-rod being connected to the upper frame so that the said frame with the upper rolls can be moved horizontally on the rails either to a position above the lower rolls or to one side 1 thereof, substantially as described.
4. The combination in a plate-straightening machine, of the housings, fixed rails, lower rolls mounted in said housings, a shaft connected to the central roll of the series, means geared to the other rolls, a frame mounted on the rails, means for shifting said frame, and upper rolls carried by the frame, substantially as described.
