FRANKLIN A. TENNEY, OF CONCORD, NEW HAMPSHIRE.
IRvON-BENDING MACHINE.
SPECIFICATION forming part of Letters Patent No. 243,174, dated June 21, 1881.
Application filed April 4, 1881. (No model.)
To all 'whom it may concern:
Be it known that I, FRANKLIN A. TENNEY, a citizen of the United States, residing at Goncord, in the county of Merrimack and State of New Hampshire, have invented certain new and useful Improvements in Machines forA Bending and Shaping Metal Bars; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
Figure l of the drawings is a top-plan view of my invention, partly in section 5 and Fig. 2 is a sectional side elevation taken on line y y of Fig. l.
The present invention has relation to certain new and useful improvements in machines adapted to be operated by steam-power, in which iron or other metal bars, when heated to a red heat, maybe bent to the required shape by compressing the metal between a movable and stationary former, having their meeting faces shaped in any form to which'it is desired to bend theiron or other metal.
The object of the invention is to improve the construction and operation of the above class of machines, whereby Agreat power and certainty of action are obtained in bringing the metal bar to the required shape, said objects being attained by the construction substantially as shown in the drawings, and hereinafter described.
In the accompanying drawings, A represents the bed-plate of the machine, which is preferably constructed of cast metal of suitable thickness to give it the required solidity.
At one side of the bed-plate A is the stationary former B, which may be cast with the same, or the bed-plate made to project beyond the former and provided with suitable boltholes for attaching thereto the former-B, which may be of any desired shape.
The bed-plate A has two sockets, a, which are preferably cast with the bed-plate, said sockets receiving the outer ends of togglearms b, which ends are of circular form to conform to the interior surface of the sockets, to which they are pivoted. The opposite or inner ends of the toggle-arms b are pivoted to a 5o horizontal bar, C, and to the opposite side of said bar is pivoted the inner ends of togglearms o, the arms at their outer ends being pivoted to a movable former, D. The convex face ofthe former D corresponds to the shape of the stationary former B, and has connected to its ends rollers d, which bear against the tracks e upon the bed-plate A, so as to prevent any irregular motion or lateral strain when being brought down or against the metal 6o bar placed upon the stationary former B.
The bar C, at one end, has pivoted to it a bar, E, said bar being pivoted at its opposite end to a cross-head, f, from which extends a piston-rod, g, said rod having the usual piston working within a steam-cylinder, F. The bar C is prevented from lifting by a metal strap, h, and a suitable rubber cushion or stop, t', is secured to the bed-plate, to stop the backward motion of the machine when the steam is re- 7o versed in the cylinder, and thereby avoid any strain.
When it is desired to operate the machine i the bar of iron is withdrawn from the furnace at proper heat and placed on the bed-plate A,
as indicated by broken lines zo w. The steam being turned on, the cross-head f, moving in its guides k, wilifdraw through the connecting-bar E the bar C in a direction toward the cylinder. As the bar C is thus being moved, 8o the toggle-arms b c will be brought to a position at right angles, or nearly so, to the bar, or, in other words, extended. The former D, being forced against theiron to be bent, presses it into shape between the faces of the movable 8 5 and stationary formers. A reversal of the engine withdraws the movable former D, so that y the iron can be removed, and leaves the machine ready to continue the work.
As previously stated, the ends of the arms 9o b o are rounded and fit closely in the sockets, so that they have a bearing on their circular ends, thereby relieving the pivots passing through them from all strain when the machine is doing its work. The arrangement of the arms b c is such that the least poweris obtained when, the bar of iron to be operated upon being nearly straight, a slight pressure will cause it to bend; and as more force is re-' in combination with the movable former D,
quired Jche arms b c assume a position more bar C, and toggle-arms b c, said bar being connearly perpendicular to the bar O, increasing nected by anysuitable means to the piston of a the power of the machine without additional steam-cylinder for imparting motion vthereto,
5 steam-pressure in the cylinder. l substantially as and for the purpose specified.
Having now fully described my invention what I claim as new, and desire to secure by FRANKLIN A' TENNEY' Letters Patent, is- Witnesses:
In a machine for bending Vmetal bars, the CARL E. KNlGHT, 1o bed-plate A, having former B and sockets a, EDWARD OSGOOD.
