TO ALL WHOM IT MAY CONCERN:v
Be it known that I, JOSEPH H. C. BAGHELDER, of Winsted, county of Litchfield, and State of Connecticut, have invented an Improved Rolling-Mill; and I do hereby declare the following to be an exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which- Figure 1 represents a front view of the machine.
.Figure 2 represents a top view of the same. v A
Figure 3 is a sectional view, showing the slide and wedge in the proper position, and their rack-and'-pinion gearing; also, showing the self-acting tongs lwith their operating-devices.
Figure 4 represents a longitudinal sectional view of the lower working-devices of the machine.
Figure 5 is a sectional view, showing the manner of hanging the bearings,`in which the cog-gearing operates..
Figure 6 represents a sectional view ofl the guard and slide, that may be substituted when the bar of iron 4 or other metal is to receive a corrugated or irregular surface. i The nature of my invention consists in the construction of a rolling-mill, so arranged that a bar of iron or other metal may be rolled to any desired taper or length; the taper ofthe bar being' regulated by means of two sectional-hinged slides operating under the bearings of the lower roll, and operated by pinions gearing into racks on the under side of each slide, Between the sections of each slide a graduated wedge is inserted, which, during the operation of the machine, causes the lower roll to gradually rise, in conformity to the taper ofthe wedge inserted, thereby giving a corresponding taper to the bar as it passes through the rolls. The length of the taper can be carried to' any extent desired, by means of these sectional slides and wedges, and is regulated by a very simple automatic device, which I will describe.
Into the lower section ofthe inner slide I insert a pin, at a distance from the end ofthe slide to correspond 3 with the length of taper the bar is to receive, vand as the slides move forward, the pin comesin contact with a i dog, which is pressed forward, and operates ahell-lever and clutch, which throws the connections of the lower shaft out of gear. The lower working-devices being then stationary, the bar passes on through the rolls, and is rolled without any taper,the rest of its length.
I also attach to the frame, and directly in front of the rolls, a self-acting feeder or tongs, that are operated by meansfof a cam-wheel, on the lower shaft, in connection with an arm or lever projecting from the lower` part oi' the tongs; this arm or lever being kept in its position against the face of the cam-wheel by a spiral spring that is attached to its upper side and to the lower side of the guide-plate in front of the rolls. The bar having been placed between the jaws ofthe tongs, with one end close to the rolls, the tongs alternately receive a backward-and-forward motion by means of the cam-wheel, which gives a regular and steady feed oi' the bar to the rolls. i i l i l A represents the bed-plate that support-s the devices of the machine. l
B B, the upright frames `supporting the cog-gearingthat gives motionto the rollsand to the various` working-devices.
C C are the upright frames thatsupport the rolls, and through which the slides with their graduated wedges operate. v
DD are the pinio'ns by which the rolls receive their motion, figs. 1 and 2.
E E, the sleeve-couplings, connecting the pinion-journals to thejournals of the rolls, figs. 1, 2, and 5.
F is the'upper roll, revolving in stationary bearings ,in the frame C C.
G is the lower roll, working in movable bearings, H H, figs. 3 and 6, that rest upon the upper faces of the sectional-hinged slides J J, figs. 1, 2, 3, 4.
The upward or ascending motion of the roll G, which gives the taper to the bar, is produced by means of the graduated wedges K, iig. 3, that are inserted between the sections of each slide J, to any distance to give the taper to the bar that may be required.
Between the movable bearings H H and the slides J J are guards, L, iig. 8, that are kept in their places by means ofpns passing into them from the under sides ofthe bearings H H; Upon the lower part of the guards L are projections, M, that it into corresponding offsets, N, rigs. 3 and l6,-,in the upper faces of theV slides J J. The object of these guards is to prevent the slides from being thrown from their proper positions under the rolls lduring their reverse motion, by the projection M of the guards L dropping and lclamping into the oisets N 'of the slides J and holding them in their proper places as soon as the wedges have passed from under the rolls.
0,1'ig. 3, are-racks, upon the under side of each slide J, that gear into and receive their motion from pinions, -P P, figs. 1, 3, and 4, upon the lowerA shaft Q, and work in the lower part of the frames C. These pinions P P and shaft Q are operated by the cog-wheel R, figs. 1, 2, 5, which gears into and receives its motion from the'lower pinion D.
T, gs. 1 and 2, are grooves in the rolls F and G, for the purpose of giving a regular and perfect finish to the edges of the bar.
U, iigs. 1, 3, 4, is a' cam-wheel on the shaft Q, the object of which is to operate the self-feeding tongs V',
S S, fig. 1, are openings through-the lower part of the frames CC, through which the slides J J operate. J
figs. 1, 2,3, by means of the lever W, figs.. 1, 2, 3, 4, that projects from the lower part of the tongs V, andeis' v kept in its position against the face of the cam-wheel by the spiral spring X, figs. 1 and 3, one end of which is attached to the upper side of the lever W, and the other end to the under side of the guide-plate Y,'gs. 1, 2, 3. The tongs V are carried forward towards the rolls by the cam-wheel U acting upon the' lever W until the shoulders of the cam-wheel strike a depression in the lever, when the tongs immediately fall back to take a new grasp upon the iron, and as the can1-wheel revolves upon the lever, the tongs are again carried forward, giving a uniform and regular feed of the bar to the rolls.
. Z, figs. 2, 3, is the lever that operates the lower jaw of the tongs and holds the bar in its proper position whilst being carried to the guides a, figs. 1, 2, 3, that conduct the rod to its proper grooves in the rolls F and G. b, figs. 1 and '4, is a pin, inserted into the lower section and edge of the inner -slide J, at a distance from the end of the slide to correspond with the length of the taper the har is to receive, and as the slide moves forward, the pin b strikes a dog, c, figs. 1,' 2, 3, 4, that is attached to one endV of a shaft, ol,'gs. 1, 2, 4, 5, working in bearings, e e, and attached to the bed-plate A.
To the opposite end of the shaft d is attached an upright slotted arm, e', figs. 1, 2, 4;, 5, which receives and carries one arm of' the bell-leverf. The opposite arm of the bell-leverf passes through, and moves backward, a horizontal slide, g.
h, figs. 1, 2, 4, 5, is a clutch, grasping the movable coupling l, figs. 1, 2, 4, 5, of the shaft Q, and is operated by the clutch-arm passing through a slot in the horizontal slide g.
V When the pin bistrikes the dog c, the dog is pressed forward, and operates the upright arm l', bell-lever f, and horizontal slide g. The slide g, in its backward movement, carries with it the clutch h, which instantly throws the lower working-devices of the machinery out of gear by means of the movable coupling l.
The lower working-devices being now stationary, the bar passes through the rolls without any taper for the balance of its length. r p
fm, igs. 1, 2, 3, 4, is a treadle, connectedtol the shaft d by means of a rod, n, figs. 1, 2, 4, andjs for the purpose of drawing the dog c to its proper place against the slide J.
p, figs. 1, 2, 3, 4, is a treadle, attached to one end of a loose sleeve, .s, upon the shaft t, gs. 2, 3, 4, of the treadle m. Upon the opposite end of the sleeve s is an upright arm, u, that gears into a shoulder, v, iigs. 1, 3, 4, on one end of the horizontal slide g.l i
The working-devicesare readily thrown into gear by 4pressing down upon the treadle p, which, by the arm i u of the sleeve s, draws forward the horizontal slide g and clutch IL with `the movable coupling l, when the machinery is again in full operation. y
w, figs. 1 and l2, is a spiral spring,l upon the shaft d, to prevent the dog c from workingkforward 'in front of l l the slide J. l
y y, figs. 1, 2, 3, are set-screws, forthe purpose of regulating the pressure 'of the boxes upon the journals of the roli F. I i
I do not coniine myself to merely rolling a bar of iron or other metal to a plain tapering surface, but design giving a bar a double-corrugated or any uneven or irregular surface that may be desired. This object I accomplish by removing ther-guards L and plain slides J, and substituting in their places guards A and slides B', as
, shown in tig. 6, with faces (working together) corresponding-to the form the bar is designed to receive. l l' 1 When the pattern-guards A.' and slides IB'I are inserted, the operation of rolling is carried ou with as great facility as though a bar were being worked up to a plain surface.
G C', gs. 5, 6, are keys, inserted into slots in the frames B -B, and support the bearings of the cogs or lpinioes D D. i
D' D', iig. 3, are screw-bolts, passing down throhgh the tops of .the frames C C, and support the bearings Y .of the roll F.
WhatI claim as my invention, and desire to secure by Letters Patent, is- Y 1. The slides J' J, withtheir racks O, movable bearingsH H, graduated wedges K, (guards L, and'pinions P P, whenarranged, constructed, and'operating as described, and forithepurpose set forth.
2. Also, the tongs V, with their lever Z, spiral spring X, lever W, and cam-wheel U, when arranged, constructed, and operating as described, and for the purpose set forth. v i
3l Also, pin b on sliding wedge, iu combination with dog c, shaft d, upright slotted arm e', bell-lever f, horizontal side g, clutch h, movable coupling l, treadles m and p, rod n, spiral spring w, looseisleeve a, arm u d h ld ll ran ed ando eratin as set forth.
