MACHINE FOR FORMING RAILWAY-CHAIRS.

SPECIFICATION forming part of Letters Patent No. 434,228, dated August 12,1890.

Application filed May 28, 1890. Serial No- 353,445- (No model.)

To all whom it may concern:

Be it known that we, VICTOR ANGERER, a citizen of the United States, and HENRY E. BRETT, a subject of the Queen of Great Britain and Ireland, and'both residents of Philadelphia, Pennsylvania, have invented certain Improvements in Machines for Forming Railway-Chairs, of which the following is a specification.

The object of our invention is to construct a machine which will bend and form to the proper shape chairs for supporting railwayrails.

The machine is especially adapted for bending the chairs described and claimed in the patent granted to Edward Samuel on the 3d day of September, 1889, No. 410,452; but it will be understood that by changing the dies and formers other styles of chairs may be shaped by the machine.

In the accompanying drawings, Figure 1 is a plan view of our improved rail-chair-bending machine. Fig. 2 is a side view of the same. Fig. 3 is an end view looking in the direction of the arrow,Fig. 2. Fig.4 is a longitudinal section of part of the machine on the line 1 2, Fig. 5. Fig. 5 is a view, partly in end elevation and partlyin transverse section, on the line 3 4, Fig. 2. Fig. 6 is a detail sectional view of part of the machine on the line 1 2,Fig. 5. Fig.7 is a perspective view of one of the pivoted blocks for carrying the bending-dies. Fig. 8 is a view of a chairblank before being subjected to the action of the machine, and Fig.0 is a view of the chair after it has been acted upon by the machine. Figs. 4, 5, 6, and 7 are on a larger scale than the remaining figures.

\Ve will first give abrief description of the operation of the machine, in order that its construct-ion, as hereinafter described, may be more readily understood.

Achair-blank is first produced in accordance with the above-mentioned patent of Edward Samuel, this blank consisting of a section of an I-bar cut to the proper length and having its web recessed, as shown in Fig.8, so as to form two projecting tongues 00 :20, adjacent to the upper flange, the lower flange constituting the base 0: of the chair. By cutting the blank in this form the web of the chair directly under the two projecting portions of the upper flange becomes a strengthening-rib for these projections when the latter are bent to the proper position. The blank thus prepared is placed on the carrier of the machine and clamped to a formenwhich is of a size and shape corresponding to that of the rail and the securing device by which the rail is confinedto the chair. The carrier then has a downward movement, carryin g the chair-blank with it past to the shaping-cams, which rotate on their axes and engage with and bend the projections 00 90, pressing them against the former, the carrier continuing its downward course until the completed chair is released from its control and isthrown out of the machine by suitable mechanism, after which the carrier returns to its first position, ready to receive another chair-blank.

The construction of the machine is as follows:

A is the frame of the machine, having suitable bearings for the driving-shaft B, which has at its outer end a belt-wheel b and is geared to an intermediate shaft 0 by a pinion 0 and spur-wheel c, said intermediate shaft C being geared to a cam-shaft D by a pinion d and spur-wheel d. On the shaft D is a cam D (shown by dotted lines in Fig. 2) for operating the beam E, the cam acting upon a pin or roller 6 on this beam, which is pivoted to the frame-work by trunnions (2, adapted to suitable boxes on said frame, and is connected to the carrier F by a link 6 The beam E is weighted atits rear end 6 so that the carrier will always be returned to the elevated position shown in Fig. 2, the cam D acting to operate the beam so as to depress the carrier and force it past the bending-cams of the machine.

The carrier F is adapted to slide in suitable ways G, which are secured to the frame A of the machine by bolts X, Figs. 2 and 4. The inner bar G, Fig. 4, of each guide G is adjustable toward and from the outer bar by means of the bolts g, Fig. 4; hence the wear on the slides of the carrier F can be readily taken up. v

All of the above-described parts may be varied without departing from our invention, as it is immaterial by what means the parts are driven, so long as the carrier is properly reciprocated.

Adapted to vertical guideways f on the car rier is the supporting-block H for the chairblank X, (shown in full lines in Fig. 5 and in cross-section in Fig. 4,) and adapted to guides on this block H is a clamp H, fitting or conforming to the rear of the chair-blank X. The clamp-block H can be moved forward in its guides on the block II to force the completed chair from the carrier, this movement of the block H being effected by mechanism described hereinafter. Pivoted to the blockII by a pin it is an outer clamp block I, the upper portion of which conforms to the shape of the outer side of the chair-blank, as shown in Fig. at, said pivoted clamp having a cam-surface '11, which rests against a project ing portion F of the carrier F. Directly above the block H and its clamps is the former J, adjustably secured in a pocket f in the carrier F by means of a bolt j and setscrewsj, Figs. at and 5. \Vhen the pivoted clamp'block I is brought to the position shown in Fig. 4-, the cain-surface 11 of said block, by its action on. the projecting portion F of the carrier, forces the block H upward, so as to clamp the chair-blank tightly against the under face of the former J, while at the same time the clamps II and I firmly press upon the inner and outer side of the blank and prevent it from moving backward or forward; hence the blank is rigidly held in position on the carrier, ready to be forced past the bending-dies, described hereinafter.

. On a forwardly-projecting portion A of the frame is pivoted at 7.: a lever K, which is connected to a slide K by a link 7.:, said slide being adapted to ways on the portion A of the frame, and carrying at its inner end a roller k bearing against the front portion of the pivoted clamp-l loek I. By moving the lever K in the direction of the arrow, Fig. 4, to the position shown in said figure the pivoted clamp-block I will be forced against the chair-blank X, and at the same time the block II will be raised by the cam i, so as to force the blank against the former J. Guided in the frame A below the slide K are two presserbars L L, having rollersl Z at their inner ends, and comprcssion-springs Z encompass the shanks of these presser-bars between the heads of the same and shoulders on the frame A. The outer end of each presser-bar is screw-threaded, and adapted to the screwthreads are nuts Z whereby the inward movement of the bars is limited. The object of these presser-bars is to keep the clamp I in contact with the chair-blank as it passes downward through the machine, the bars yielding, however, to aceommodat c any i rregularities in the face of the blank or of the clampingblock.

On each side of the vertical carrier F are sliding blocks M M Fig. 5, guided transversely Between a nut m on each bolt m and the block M is a spring M, and on the inner end of said bolt is a nut m which thus serves to limit the inward movement of the block M, under the action of the spring, the latter, however, permitting a certain amount of lateral yielding of the block as the blank passes through the machine. Mounted in bearings on each side block M are the trunnions a n of the side die-carrier N, (shown in detached view in Fig. 7,) and adapted to a pocket n. In each carrier is a die N, one of these dies being shaped to bend the short lip 00 of the chair and the other being shaped to bend the long lip w, as clearly shown in Fig. 5.

The bending-dies may be secured to their carriers in any suitable manner. In the present instance they are secured by set-screws n passing through the carriers and bearing against the dies.

The carrier N is made in the peculiar form shown in Fig. 7, and on each carrier is mounted a strikeplate s for contact with a projection 3 on the side of the block H, these projections being given a peculiar shape in order to provide for the correct rotating motion of the carriers N in the manner described hereinafter. As the projections s strike the plates s on the carriers, they turn said carriers in the direction indicated by the arrows in Fig. 5, the relative position of the plates .5- and dies N being such that when the carriers are moved by the projections s the dies will pass under the lips 00 w of the blank and gradually bend them around the former J as the carrier F descends. The shape of the dies depends upon the shape and size of the chair to be formed, as will be readily understood.

livoted to the lower portion of the frame of the machine is a discharge-lever consisting of two arms T tied together bya cross-bar T an d by the pivot-shaft T On the side arms are spring-plates t, adapted to strike the chairon opposite sides of the carrying-block, and thus force it therefrom, an inclined portion p of the carrier F striking the bar 'I" and forcing the discharge-lever forward in the direction of its arrow, Fig. 4, the cross-bar T finally enteringa pocket p, formed in a projection on the carrier F. A coun ter-weight on the shaft T restores the lever T to its normal position when the carrier F rises. Secured to one of the arms '1, Fig. 4-, of the lever is a plate U, having pins to a, and resting between these pins isan arm U, pivoted at u to a projection on the frame of the machine. Carried by the arms U is a curved plate U, recessed to permit the passage of the clamping-block I, this plate being counter-weighted by an arm a, secured to the shaft 14, and the weight being sutiicient to return the plate to its original position, (shown in Fig. 4-,) but when the formed chair is pushed onto the plate it falls in the direction of its arrow, Fig. 4., thus precipitating the chair off the plate onto the ground or into a receptacle, the pins u 1! limiting the motion of this plate.

' Projecting from the base of the machine is a standard R, having an inclined face 1" at its upper end, and as the carrier F moves downward the upper portion of the standard passes into the clamp-block H, which has an inclined face h. (Shown by dotted lines in Fig. 4.) Consequently when the face r comes into contact with the face it the standard forces the clampblock Hf. outward, the block thereby forcing the bent chair from its seat on the supporting-block H, and thelever T then pushing the chair onto the delivery-plate U It will be understood that the pivoted clamp-block I falls clear of the formed chair after said block passes the lower roller Z of the presser-bar L, and at the same time the block H is lowered, so that the chair is free to be displaced from the suppoi'tingblock.

The pinion d is loose on its shaft 0, and on the hub of the pinion is one jaw d of aclutch C, the sliding jaw c of the clutch turning with but sliding on its shaft, and being operated by a longitudinal shaft 0 having arms 0 which engage with a grooved portion of the jaw, the shaft 0 having at the outer end a handle 0 by manipulating which the operator can throw the clutch into and out of gear, and thus readily start and stop the machine. We also provide automatic mechanism for stopping the machine when the carrier F has reached a position ready to receive another chair-blank.

A tappet o, hung to a stud v on the frame, projects into the path of the carrier F, and an arm n on this tappet is connected to an arm 173 of the shaft 0 by a rod 12 so that on the return movement of the carrier the tappet will be raised, thus forcing the clutchsleeve 0 out of gear. This mechanism, however, is not essential in carrying out the invention On the carrier F are inclined projections q q, Fig. 5, which fit snugly against the camt'aces g on the die-carriers N-when the carrier F is down, so that when the carrier is returning the projections q q permit the die-carrying blocks to return gradually to their nor-. mal position under the influence of the counter-weights of the said carriers, giving them a corresponding motion with the one on the downstroke, so that all the parts of the slide will pass the dies without striking them.

It will be evident that a machine might be constructed in accordance with ourinvention in which the supporting and clamping devices for the blank are stationary, while the diecarriers and other parts which now occupy a fixed verticalposition are mounted upon a rising and falling carrier;but the construction shown is preferred.

Having thus described our invention, we claim and desire to secure by Letters Patent- 1. The combination in a rail-chair-forming machine, of a former, chair-blank supporting and clamping devices, side bending-die, and
