MORRIS H. BROWN, OF NEV YORK, N. Y.

RAIL, BAR, OR PIPE BENDER.

SPECIFICATION forming part of Letters Patent No. 630,484, dated August 8, 1899.

Application filed May 19,1899. Serial No. 717,429. (No model-l To all whom it may concern:

Be it known that I, MORRIS H. BROWN, of New York, State of New York, have invented a new and useful Improvement in Rail, Bar, or Pipe Benders, which invention is fully set forth in the following specification.

In my Patents No. 383,168, dated May 22,

1888, and No. 520,876, dated June 5, 1894,, I have shown and described improved railbenders, more particularlyof a portable type, adapted, for example, to be applied to rails while in place on a railroad for straightening or bending the same. The present invention relates to improvements in rail, bar, or pipe benders of what may be called a stationary typethat is to say, the rail-bender is put in place in a railroad-yard, for instance, and the rails or bars to be bent or straightened are brought to the bender, which is adapted to accommodate any size or shape of rail or bar.

The machine herein described is specially designed to fill a long-felt want for an apparatus of this kindadapted for use in the yards or terminal stations of railroads, where surface-bent, crooked, and twisted rails are sent preparatory to being forwarded to the rollingmill to be rerolled.

The improvements constituting said invention will behest understood by reference to the accompanying drawings, wherein Figure 1 is a perspective view; Fig. 2, a top plan view, partly in section. Fig. 3 is a sectional detail view through the eccentric, and Figs. 4 and 5 are details of dies.

Referring to the drawings, A A are side bars formed with upwardly-opening jawsor hooks b at one end and converging toward their opposite ends, in which the eccentricshaft D is journaled. These bars are held together and'stiffened by a secondary triangular frame E, secured thereto by bolts. The ram is composed of two parts F and F, 0011- pled' by an adjusting-sleeve G. Part F rests loosely in a socket at one end of sleeve G, while part F is screw-threaded in a socket in the other end of said sleeve. adapted to be turned by a pin g, removably inserted in opening g thereof. Theouter end of part F is pivoted between two links H by The sleeve is means of the bolt 1. The other ends ofs'aid links engage about the eccentric d on the shaft D.

M is a dog pivoted at m to one side of the triangular frame E and adapted to engage a series of notches or teeth formed in the side of the ram or plunger F to hold the latter in the position to which it has been moved by the eccentric.

As thus far described the apparatus shown in the drawings does not materially differ from that described in my Patent No. 520,876, above referred to, except in that the jaws at the ends of arms A open upwardly, the importance of which will be more fully explained hereinafter.

K represents the lever for operating shaft D, said lever being provided with the usual means for applying a 'wooden handle L. It will be observed that in the present case the position of this lever with reference to the jaws at the ends of the armsA is the reverse of that shown in my patents referred to-that is to say, said lever projects upwardly from the upper side of the frame and the jaws open in the'same direction.

N represents the side beams of a triangular wooden frame, preferably of wood, which are connected by three cross-beams O 0 0 The rail, bar, or pipe bender proper is supported on this frame, the ends of eccentric-shaft D resting against suitable blocks q, to which it is secured by bearing plates or eyes r bolted to said blocks. The jaw ends of the side bars A engage betweenthe side beams N and fit in notches o 0, cut in cross-beam O at the wide end of the triangular platform. At their middle the bars A rest against the wooden cross-beam O".

s are suitable rollers mounted one on the upper edge of each of the wooden side beams N, adjacent to the openings of the jaws b b. A rail, bar, or pipe to be bent rests upon and is movable on these rollers in bringing it to the proper position for the action of the ram.

Suitable dies are secured to the jaws b b of side bars A A by bolts 25 passing through an opening in said jaws, as clearly shown in Fig. 1. An iron block u is placed between the end of the ram and the rail, bar, or pipe to protect the point of the ram and give free movement when the leveris raised.

Of course various forms of dies and blocks may be employed, according to the configurahaving semicircular recesses in the faces thereof and adapted for use in bending pipe or bars of circular cross-section. In said figures, 4 represents the die for the jaws 11,--

while r is the block for the ram.

ram I provide a suitable scale m, as clearly the latter fitat their jaw ends, and means for securing the eccentric-shaft to the frame.

2. In a rail, bar or pipe bender, the combination with two metallic side bars having upwardly-opening jaws at one end and converging at their opposite ends','of aram slidingly mounted between said bars, an eccentric for imparting pressure to the ram, an'eccentricshaft j ournaled in the metallic side bars, and an operating-lever for said shaft, a triangular-shapedframe comprising two converging side beams extending substantially parallel 1 to the metallic side bars and between which On the upper surface of the part F of the the latter fit at their jaw ends, means for securin g the eccentric-shaft to the frame, and rollshown in Fig. 2, whereby (and by adjusting said part]? by manipulating the sleeveG) the parts maybe set to secure'any desired throw of the ram, and thereby impart a predeterm ined'bend to the rail orbar being acted upon.

The operation of the device will be obvious from the foregoing description. It will also be obvious that the apparatus may be moved for short distances by dragging the same over the ground, the wooden frame acting as a sled.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a rail,bar or pipe bender, the combination with two metallic side bars having u p wardly-opening jaws at one end and conver ging at their opposite ends, of a ram slidingly mounted between said bars, an eccentric for.

imparting pressure to the ram, an eccentricshaft journaled in the metallic side bars, and an operating-lever for said shaft, a triangular-shaped frame comprising two converging side beams extending substantially parallel to the metallic side bars and between which ers mounted on the side beams adjacent to the jaw-openings in the side bars.

3. In a rail, bar or pipe bender, the combination with two metallic side'barshaving upwardly-opening jaws at one end and converging at their opposite ends, ofa ram slidingly mounted between said bars, an eccentric for imparting pressure to the ram, an'eccentricshaft journaled in'the metallic side bars, and an operating-lever for said shaft, a triangular-shaped frame comprisingthe converging side beams extending substantially parallel to the metallic side bars and between which the latter fit at'their jaw ends, means for se-" curing the metallic frame to the platform, and removable dies for'tlie jaws and a block for the ram.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
