RAILROAD-CHAIRS.

Specification forming part of Letters Patent No. 7,330, dated April 30, 1850; Reissue No. 386, dated August 12, 1856.

To all whom it may concern:

Be it known that 1, WILLIAM VAN ANDEN, of Pen ghkeepsie,Dutchess county, New York, have invented certain new and Improved Machinery for Making Bailroad-Ohai rs of 'Wrought-Iron; and I dohereby declare that the following specification, taken in connection and exact description thereof.

Figure 1 is a front elevation of the machine, with the upper die in the act of descending to clamp the blank fast after cutting it off the bar and punching the recesses therein. Fig. 2 is a section on. the line x 00 of Fig. 1, with the exception of the cogs-and shafting, which are shown in elevation. Fig. 3 is a perspective view of the upper clamp and die with its parts closed together. Fig. at is a perspective view of the lower jaw or clamp, and also of the shears and benders. Fig. 5 is a vertical section through both clamps and the shears and their accessories. Fig. 6 is a view of the upper die when its parts Fig. 7 is a view of the acting surface of thelower jaw or clamp. Fig. 8 is an elevation of a grooved track which governs the opening and closing of the parts r" the upper die. Fig. 9 is a side elevation o'the upper die and some of its accessories, with a finished chair in the act of being discharged therefrom. Fig. 10 is an elevation of the interior surfaces of the parts of the upper jaws. Fig. 11 is a view of a chair-blank cut and punched prior to the severing and form- Fig. 12 is a birds-eye view of a completed chair. Fig. 18 is a side elevation of the same. Fig. 14 is a perspective view of one of the cutting and bending shears.

Prior to the date of my invention wroughtiron railroad-chairs were of two classes-first, those partially rolled into shape in a rollingmill in long bars and then sawed into proper lengths, and, second, those formed usually by hand or hand-tools out of blanks of plate-iron of nearly a uniform thickness.

My invention relates to the latter class of chairs, and by means of the machine. devised by me they may be formed by machinery without any aid from an operator further than is necessary to feed the machine. In forming such chairs there are a series of operations necessary to be performed, which may be enumerated as follows: first, the severing of a blank of proper size from a bar of wroughtiron; second, the clamping of the same firmly between dies or clamps, so that its plane surface may be preserved at all parts except the lips; third, the severing of the lips; fourth, the bending of such lips into proper shape to embrace a rail, and, lastly, the discharging of the chair from the machine. To these may be added the punching of proper holes for the reception of spikes, when such are needed.

lVith these series in view the nature of the first part of my invention consists in clamping a chair-blank firmly between two surfaces, so

that it may be submitted to the action of proper shears or their equivalents, the manner hereinafter set forth.

"he nature of the second part of my invention consists in severing the lips of a chairblank thus clamped by proper shears or their equivalents, acting substantially as herein described.

The nature of. the third part of my invention consists in giving to such shears a motion in two directions, so that they may first sever the lips and bend them at right angles to the rest of the blank, and afterward approach each other and close the lips together, so that they may conform to the shape of the base of a rail, substantially as hereinafter specified.

The nature of the fourth part of my invention consists in constructing a die,part of which acts as a clamp and part as a former, in two pieces capable of approaching to and receding from each other, substantially in the manner and for the purposes hereinafter set forth.

The nature of the fifth part of my invention consists in discharging a chair from a partingdie by ahook or bar, a positive motion, and acting substantially as described.

The nature of the sixth part of my invention consists in combining in a single machine clamps one of which acts as a former and shears and benders, and a discharger, substantially in the manner herein specified.

substantially in or its equivalent, having 1 I thrown outward from In the drawings the same letters refer to the same parts in allthe figures, and by their aid I will proceed to describea machine constructed aecordingto the principles of my invention. A strong frame, which serves to assemble all parts of the machine, is shown at AA, and in it are mounted two shafts, b b n n. The latter of these carries two cog-wheels, one of which, t, is a driver actuated by a pinion, P, receiving motion from any proper prime mover, and the other, e, engages with a wheel of the same size, w, mounted on the shaft Z. These two shafts, therefore, rotate in opposite directions with the same speed. 011 the ends of each of these shafts are formed pins, eccentric to the,

shaft, and acting, in fact, as crank-pins n and Upon the front of the frame are secured cheeks G G h h,which, in connection with the frame, form guides, in the former of which 1 slidesa compound clamp and former or die, Ff,

and in the latter moves a shear-stock, w w. Between these checks a stationary clamp, E, is firmly secured to the frame. The compound die and the shear-stock rise, fall, and pause at proper intervals in consequence of the crankpins moving in heart-shaped cam-boXes t andj.

To the shear-stock are secured, by hinges X X, two shears, VV,which maybe faced with steel on their cutting-surfaces, as at 8 8, and are hooked over, as at 7 7, so that they may bend or form the lips after they are severed. These shears being hinged, may approach or reeede from each oth er,and are kept apart by a spring, d, located in a recess in the stationary clamp; but as it is necessary that they should be caused to approach forcibly in order to bend the lips over the former they are provided with small studs or ears 5 b, which at times strike against vibrating chocks a a, located in recesses in certain cheeks, c c, bolted onto the front of the frame. The ends of these chocks rest always against the shears or their ears, and form with the latter a sort of togglepress. The upper surface of the lower and stationary clamp, E, maybe faced with steel, and conforms with the shape of the bed-piece or bottom side of afinished chair, (see Fig. 7,) and may have formed in it sockets p p,'for the reception of punches at m mm, secured in the compound clamp and die. The shears rise through the the size of a chair lip. The upper or compound clamp and die has a double stock, Ff, whose parts are hinged to each other at J. The latter has projecting from it tongues 3 3, which slide in the guide formed by cheeks G and the frame at B, and the former is fitted with a pin, D, whose ends enter bent grooves H H, formed in projections from the cheeks G. As this compound die rises and the pin enters that part of the grooves H which is not vertical, the part f is by its own ascent and through the intervention of the pin and grooves the part F, so that the faces F F (see Figs. 6 and 9) are separated from the face f. The lower part or acting recesses c c, which are of surface of the compound the upper surface of the a bar or cross-piece, 3 separating them. (See Figs. 5 and 10.) These recesses permit the shears and benders to rise, and in them the lips are bent. f is that part of the acting face which at times swings outward and separates from the other part of the face F F. From the inner face off projects a lug, f which when the two halves of the clamp and die are closed enters a recess, 15, in the corresponding face of F, prevent one half of the die from sliding on the other, and relieve the hinge at J. From the inner face of the inner die also project two hooks, R R, which when the halves are in contact lie in the rear part of the recess ll 12, and when one half the clamp and die separate from the other wipe along the sides of the bar 3 A shear-blade, I, may be attached to the swinging half of the upper die, so that it will sever off a length of proper size from a bar of iron, which should be entered into the machine until it strikes the-stop 4.

In Fig. 11 is shown on a larger scale a chairblank cut and punched at p p, with dotted lines indicating the line of severance ofthe lips; and in the use of my apparatus T. generally intend thus to prepare the blank in a separate machine before clamping, cutting, and bending it, as chairs differing to some extent in size may be made in the same machine, and the holes may be punched according to the directions of those who use the I chairs. 7

In Figs. 12 and 13 are represented an elevation and plan of finished chair, showing clearly how the lips are cut and bent so as to en1 brace the lower flange of a rail.

For the sake of convenience l have attached to the rear of the machine a shears, as at 17, where the blanks may be out before they are entered between the clamps.

In the action of the machine, supposing it to be supplied with a heated blank of proper size laid upon the lower or stationary clamp, the compound clamp and die commences to descend, and as it descends the pin D enters the vertical part of its containing groove, whereby the two halves of the die are closed together. As the diedescends it rests upon the blank,a.nd then clamps it firmly down up: on the stationary clamp or jaw, holding it there, as in a vice, while the pine travels over that part of the heart-shaped slot which is concentricin its curve with the upper shaft. Vvhile the blank is thus held the shear-stock, with its shears and benders, ascends and severs the lips against the edges of the face of the upper die,which then act as stationary jaws, and as the shears ascend they bend thelips upward until the ears I) commence to press against the vibrating chocks a (t.
