"METAL-BENDING MACHINE.
SPECIFICATION forming part of Letters Patent No. 643,354, dated February 13, I900.
Application filed April 10, 1899.
To 001% whom it may concern:
Be it known that we, MAX W. HENIUS and JOHN HERROLD, citizens of the United States, and residents of New York, in the county of Kings andState of New York, have invented with a portion of the device for feeding the corset-steels broken away. Fig. 3 is a vertical section from front to rear through the machine in the plane of the line 3 3 of Fig. 2. Fig. 4 is a top plan view of the machine with the rotary table, which carries the corset steel I hoppers and the stationary table, removed.
Fig. 5 is a front view of the machine, the upper portions of the hoppers being broken away. Fig. 6 is a rear view of thesame. Fig. 7 is a plan view with the top of the frame removed. Fig. Sis a vertical section from front to .rear through the upper portion of the machine, the parts being in the position which they assume when forming a bend in the corset-steel and the steel-feedingdevice removed.
Fig. 9 represents partial front and edge views I of one of the steels after it has been bent;
and Fig. 10 represents a detail view ofa portion of the stationary table, showing the inclined way at its periphery for directing the corset-steels as they are brought successively into position into the steel-receivingslot of the machine.
The framework of the machine comprises'a base A, side frames at a, rigidly spaced apart by cross-bars a and a top a The top a has Serial No. 712,374.. (No infidel.)
by shaftsb and c, mounted to rotate in suitable bearings in the side frames at a, the bearings for the front roll-shaft I) being stationary andthe bearings for the rear roll-shaft c having a limited sliding movementtoward and away from the front of the machine.
These rolls B andC are located near the .top
of the machine beneath the steel-receiving opening a An auxiliary frame is hinged within the casing onthe shaft '0, which frame comprises a pair of side plates D D' and a cross-bar (1, connecting their lower ends. A
bending-roll E is carried by a rotary shaft 6, mounted in stationary hearings in the side plates DD of. the auxiliaryframe, thesaid shaft beinglocated a short distance. below the I shaft 0 of the rear roll. I I
. A rotarycam-shaft F is mounted in adjustable bearings in the side frames at a, each of the said bearings of the shaft F being'capa rior to 'the side frame with a drive-pulley f by means of which the shaft may be driven from a source of power. (Not shown.) a
The rotarymovement of the shaft F is imparted to the front roll-shaft Z) by a gear-wheel f on the shaft F between the drive-pulleyf and the side frame mintetmediate gear-wheels G G, mounted on stub-axlesgg, and a gearwheel I), carried bythe end ofthe "said shaft 1). Rotary movement is imparted from the front ro1l-shaft b to the rear rollshaft 0,
whether the rolls are closer to or farther from each other, by a gear-wheel b on the shaft 17 and a gear-wheel don the shafts, both of which gears are provided with extra long teeth, so as to permit a considerable move- I ment toward and away from each'other without being disconnected. Rotary movement is imparted to the lower roll-shaft e by means I h, mounted in theside plates D l) of the auxiliary swinging frame.
A swinging movement is imparted to the auxiliary frame by a pair of cams f f carried by the shaft F in position to engage the rear edges of the side plates D D. A spring 61 leads from the cross-bar d of the swinging frame to a bracket d carried by one of the cross-bars a The pivot-shaft c of the swinging frame is caused to slide toward and away from the front of the machine at predetermined intervals during the swinging movement of the auxiliary frame to alternately permit the rolls B and O to engage the rear portion of one steel to bend it and to permit the advance portion of the next succeeding steel to pass freely between the said rolls. This movement is accomplished by providing stop-pins I 1, projecting inwardly from the side frames a a in position to engage the front edges of the side plates D D at the top of the swinging frame, and a cross-bar 1 mounted in sliding bearings in the side frames at a, which cross-bar iscaused to engage the rear edges of the side plates D D. This cross-bar is adjusted by screws t, extending from the back of the side frames into engagement wit h the sliding bearings of the said cross-bar.
By adjusting the bar 1 the greatest distance between the rol-lsB and C may be regulated to suit steels of different thicknesses, and by adjusting the bearings of the shaft F the amountof bend to be imparted to the steels may also be regulated. t
A stationary table J is mounted on a suitable supportj, secured to the top of the machine, upon which table is mounted a rotary table J. The stationary and rotary tables are preferably of disk shape of about the same diameter.-
The rotary table J" is provided with an annular series of f unnel-shaped hoppers J having their lower ends provided with corsetsteel-discharge openings], extended through lar series of abutmentsas, for instance,holes the rotary table J, so that when the corsetsteels are inserted into the funnels their lower ends will rest upon the stationary table J.
The stationary table J is provided with a downwardly-extended way or guide 7' at its periphery adjacent to the steel-receiving slot a in the top a of the casing for directing the lower ends of the several steels into the said slot a as they are brought successively into position over the same. I t
The means which we employ for imparting a step-by-step rotary movement to the table J comprises the following parts: A dog K is mounted to slide forwardly and rearwardly on the top a of the frame, the free end of the said dog being fitted to engage an annuj in the rotary table J. This arm 70 of. the
and its other arm engaged by a cam f, car
ried by the shaft F. The rocking lever L is held in engagement with the cam f by a retracting-spring Z, leading from the lower arm of the hopper to one of the cross-bars a of the frame.
A spring-actuated arm 70 is carried by the top a of: the frame with its free end in engagement with. the periphery of the rotary table J. The said table is provided I with notches 70 corresponding to the hoppers J arranged to receive the end of the, arm 70', so that the said arm may hold the successive hoppers temporarily in their positions over the steel-receiving opening a in the top a while the arm 70 of the dog is brought back into position to engage its next succeeding ble M,h aving downwardly extended branches m m, which are secured to the side frames at a by bolts m which pass through elongated slots m in the said ears. This stop may be adjusted toward and away from the bending-rolls, so as to determine the point on the steel which is inserted within the machine at which the bend shall be started.
An adjustable discharge-plate N is carried by the auxiliary swinging frame, which plate is provided with ears n at, having verticallyelongated slots a, through which pass clamping-bolts a for clamping the discharge-plate in any desired adjustment. This dischargeplate'N is fitted to engage the advance or lower end of the steel as the frame is swung forwardly and positively swing the said steel outwardly away from the machine as it is being bent, thus preventing any tendency on the part of the steel to stick in its first position within the machine.
In operation the corset-steels to be bent are dropped into an annular series of hoppers J As the machine is operated the dog K will he slid back and forth by the rocking of the lever L, thus bringing the steels successively into position to drop into the opening a in the top a at the proper intervals. As each of the steels is dropped from its hopper into the machine the rolls B and O are moved a distance apart sufficient to permit the steel to fall freely until its lower end rests upon the stop M. The auxiliary frame is then swung forward, thus bringing the two rolls B and G into contact with the opposite faces of the steel and the roll E into engagement with the inner face of the steel to bend it partially around the roll B. At the same time the discharge-plate N will swing forward and positively free the lower end of the steel from the adjustable stop M. y
By the use of'the plurality of hoppers for feeding the corset-steels into the machine the machine may be operated at a highrate of speed, thus turning out a maximum number of bent steelsin a minimum space of time.
It is evident that slight changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of this invention. Hence we do not wish to limit ourselves strictly to the structure herein set forth, but
What We claim is- 1. In a metal-bending machine, a movable device for containing a plurality of strips of metal, bending-rolls arranged to receive the strips between them, means for operating the bending-rolls and means under the control of the bending-roll-operating means for moving the strip-containing device into position to permit successive strips to fall into position to be engaged by the bending-rolls at predetermined intervals, substantially as set forth.
