CASTING CLAMPS FOR RAILWAY-RAILS.

SPECIFICATION forming part of Letters Patent No. 531,865, dated January 1 1895.

Applioationfiled July 21,1894- Serial No. 518,22. (No model.)

To aZZ whom it may concern.-

Be it known that we, EDWARD SAMUEL and Vrcron ANGERER, both citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Casting Clamps for Railway-Rails, of which the following is a specification.

Theobj ect of our invention is to so construct a device for holding a series of rails in position while molten metal is cast around the joints that they will be perfectly rigid during the casting and can be adjusted so as to accommodate crossing structures arranged at diiferent angles. Our invention is based on the Patent No. 490,941, dated January 31, 1893.

In the accompanying drawingsz-Figure 1, is a plan view illustrating our improved device. Fig. 2, is a sectional view on the line 2-2, Fig. 1; and Fig. 3, is a view of a modification.

A is the bed plate, preferably provided with a downwardly projecting flange (Land in the bed plate is a series of slots to adapted to receive the confining bolts by which the lower frame B is secured to the bed. In the present instance there are four frames having base flanges (2 over which extend clips 0 secured to the bed by the confining bolts 0'. 0n loosening the bolts c'any one of the frames Bean be moved toward or from the center so that they can be set for crossings of diifererent angles.

Mounted above each lower frame 13 is an upper clamping frame D between which and the lower frame are clamped the rails which are to be secured together by casting.

Extending from the lower frame B are rods 01 having slots in their upper ends, through which are passed the confining wedges d. These rods pass through openings in the upper clamping frameD and confine said frame to the rails and to the lower frame. The bars making up each frame are slotted in the present instance and adapted to the slots are adjustable bolts e carrying at one end clamp plates E which are shaped to fit the rail as shown in Fig. 2, so that when the rails are set in the frames, as shown in Fig. 1, at the angle desired, the upper and lower clamp plates E The framesB and D are made of a size to accommodate the crossing rail only at the junction, but they may be made of different sizes without departing from our invention and the construction of the clamps may be modified.

In making a cast joint the lower clamp frames are first adjusted on the bed plate so as to properly accommodate the rails when arranged on the proper line. The rails are then adjusted on the lower clamp frames and the adjustable clamp plates E of the lower frame are set so as to be in proper position to receive the rails and when the rails are set the upper clamp frames are mounted upon the rails and their plates E adjusted so that when the wedges are driven the rails will be rigidly secured to the clamping frames, after which the mold can be made and the couplings cast so as to rigidly unite the rails.

In some instances slots may be made in the flange b of the lower frame B and a common bolt used and the cross bars need not be slotted, the clamp plates Ein this instance being secured to the bars in any suitable manner, as shown in Fig. 3.

e claim as our invention 1. The combination of the bed plate, and two or more sets of clamping frames between which the'rails are mounted, thelower frame of each set being adjustable on thebed plate so that the several frames can be arranged to accommodate track structures of difierent angles, substantially as described.

2. The combination of the slotted bed plate, a series of lower clamping frames, bolts adapted to the slots and adapted to lock the frames to the bed, with upper clamp frames between which and the lower clamp frames the rails are secured, substantially as described.

3. The combination of the slotted base plate, the lower clamping frames secured thereto, adjustable blocks on the clamping frames, the upper clamping frame, and adjustable blocks thereon, substantially as described.

4:. The combination of the base plate, the slotted lower clamp frame secured thereto, clamp blocks having bolts adapted to the names to this specification in the presence of two subseribing witnesses.

- EDWARD SAMUEL. slots the upper clamp frame also slotted 5 clam p blocks having boltsadapted to theslotsz VICTOR ANGERER' and rods tying the two frames together, sub- W'itnesses:

stantially as described. WILLIAM A. BARR,
