MACHINE.
SPECIFICATION forming part of Letters Patent No. 306,793, dated October 21, 1884.
Application tiled January 2, 1884. (No model.)
To all 117mm, it may concern.
Be it known that l, ALFRED WILBUR, of Allegheny City, in the county of'Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Flanging-Machilies; and I do hereby declare that the fol-v lowing is a full, clear, and exact description o f the same.
My invention relates to an improvement upon the anginginachine for which I was granted Letters Patent No. 274,872, March 27, 1883.
The essential features of this machine, which is usually termed an outside i'langing-mal chine, were a pair of Hanging-rollers revolving in a vertical plane, a pivoted table adapted to be raised from a horizontal to a vert-ical position, and a revolving disk carried by the table and adjustable thereon, to which the boilerhead or other plate to be flanged was attached, so as to revolve with it as the table was raised. The revolving disk or plate carrier was journaled in a sectional box which was adjustable in a slot in the shifting table, and when in proper position was held rigidly in position by a lockingbar pivoted on the table, which entered a slot in the side of the box and forced it against the opposite side of the slot.
rlhe object ot' my present invention is to obviate a difficulty which has been found to occur in the practical operation of the machine as thus constructed-viz., the slipping of the box and disk in the slot of the table when held only by the frictional cont-act of the smooth faces ofthe box and locking-bar; and my invention consists in providingthe said box with a sunken corrugated orserrated face-plate, and in corrugating or serrating the bearing-edge of the lockingbar, so as to afford a firm and rigid. connection.
I have illustrated my invention in the accompanying drawings, in which Figure 1 is a front elevation of the table and a side view of the machine. Fig. 2 is a horizontal section through the table.
A represents the frame or standard of the l machine B, the upper Hanging-roller, and C.
the lower Hanging-roller.
D is the table, pivoted at l in bearings in the frame, so as to be capable of adjustment from a horizontal to a vertical position. The table is slotted at g, and in this slot slides the adjustable sectional box s, in which isjournaled the disk r. The-arbor orjournal of the disk r is hollow, and through it extends a bolt having a nut, u, by means of which the boilerhead or other plate is secured upon the face of the disk.
In the side of one of the sections of the box s is a deep slot or recess, in which is secured by bolts a hardened face-plate, t, provided with sei-rations t. The slot inthe box is of such depth that the face-plate only partially fills it, leaving a recess into which fits t-he edge of the locking-bar f2. This bar is pivoted to the face of the table at v, and is adjusted by means of a screw-bar, w, the threaded portion of which extends through a nut, w. of the locking-bar is serrated like that of the face-plate, and when forced against it holds the box, disk, and plate rigidly in position, clamping the box between itself and the opposite edge of the slot q. It is impossible for the box to sli p. however great the pressure during the operation of Hanging, and the efficiency of the machine is by the use of this device greatly increased.
Having thus described my invention, what I claim is In a Hanging-machine, the combination of theiianging-rolls, the pivoted slotted table, the pivoted plate-carrier, the recessed box having the serrated plate, and the adjustable pivoted locking-bar having a serrated edge, substantially as and for the purpose set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
