RAILROAD-TIEAND FASTENING.

, SPEGIFICATIQII forming-part of Letters Patent No. 283,076, dated August 14, 1883.

Application Ifiled September 25, 1882. (No model.)

To all whom it may concern.- Be it known that I, Josnrn L. CHAPMAN, 0 Philadelphia, State of Pennsylvania, have invented a new and, useful Improvement in Railroad-Ties and the Mode of Securing the Rails of the 'Iie; and I do hereby declare the following to be afull, clear, and exact description of the same, referencebeing had to the accompanying drawings, making part hereof.

The nature, of any invention willbe fully apparent from the following specification and claims.

In the drawings, Figure 1 is a cross-sectional view of the rail-and. connections andpart of the channel-bar tie on the linevX Y of Fig. 3. In this view the channel is uppermost, while the plain face of the bar is up on the ground; Fig.

' 2, a plan view of the form ofconstruction shown in Fig. 1; Fig. 3, a cr0ss sectionalview on the line V W of Fig. 2; Fig. 4, an outline side view of a tie formed of two plain upper and lower plates of iron held apart by inter posedblocks secured between them, also showing the rails in place, with their fastenings. Fig. 5 is a detached view of the clamp 0, showing its lower side, illustrating also the form of the heel or lug G, which projects down into the hole F of the bed-plate E, and alsothe shoulder G, which sets up against the edge of the base of the rail. 1

Though the tie may be made in the various forms shown, I shall confine my description more to the form shown in Figs. 1, 2, and '3, where the channel-bar tie is shown with its plain face down, adapted to be set upon the ground with the channeled side uppermost.

A is the tie, formed of channel-iron. B is the rail. G G are block-clamps for holding the rail down upon the bed-plate E, which bed-plate is secured to the web of the channel bar or tie by .means of rivets E E.

chamber is protected from the entry of dirt or earth from the ground beneath by the interposed tie, upon which the bed-plate E rests. The-hollow chamber is thus prevented from clogging up, whereby the head of the bolt is 1 enabled to freely enter it.

7 The T-head of the bolt is inserted into this opening F, and the boltis then pushed toward the rail. shaped head' will thus be forced underthe lower edges of the narrow slot F, while the neck of the bolt close to the head will fit closely in this slotF, the screw-threaded end .of the bolt projecting upward out of the slot. The clamp 0, being pierced with holes to receive the bolt, is pushed down over this screwthreaded end of the bolt, the heel G, Fig. 2, of the clamp setting down and fitting closely into the opening F, (see Fig. 1,) while the side edges ofthe clamp-the latter being wider The T- than this opening-will overlap the opening and enable the side edges of the rear end of e the clamp to rest down upon the bed-plate E. Asthe screw-threaded end of the bolt D pro j ects up through the clamp, (see Figs. 1 and 3,) screw-nut D is set upon the bolt end, thus drawing the clamp tightly down upon the rail, as shown in Fig. 1. A description of the modeof securing one of these clamps answers for all, as they are all duplicates.

H is a thin layerof rubber, felt, leather, or

1 other suitable packing, designed to remove,

asmuchas possible, the effects of the concussion of passing trains upon the iron conneoti'ons of the tie and rail and to deaden the sound.

= While I havedescribed the bolt D as being T-headed, it may be round-headed, or a common square-headed bolt, the head constituting flanges or shoulders to hold the bolt down when passed into the slot F. l I i I make the bed-plate E of cast iron orsteel, the holes for rivets E E and openings F and slots F, with a space beneath the slot and opening to receive the bolt-head, being cast in the bed -plate near each end, as shown,,when

the bed-plate is formed. The holes in the tie to receive the rivets E are punched through the tie.

Although I have described channel-iron as being the best adapted for my purpose, I can, if it is desired, use a plain flat bar of iron instead of the channel-iron; but channelir0n.is

preferable in the position shown inFigs. 1, 2, and 3, as the flanges of the channel-iron form IOO . v for the rivets are cast in them at the foundry .where they are made, so as to correspond eX- actly with the punched holes in. the ti es The bed-plate and ties are thus ready to be put to 15 gether immediately 011 being completed, and to hold the rails at a proper distance apart, ac cording to the gage desired. Thus the trouble and delay incident to laying railroadtracks and keeping them apart at the proper 2o gage are avoided, as the rails cannot help being held apart at the proper gage immediately on being laid upon my ties. A small hole or opening or channel, I, is cast in the lower face of the bed-plate, to permit the escape of water- I 2 5 which may gather between the rails.

While the clamp O impinges with that edge next to the rail down upon the base of the rail,

a small shoulder, G, (see Fig. 5,) sets against the edge of the base-flange of the rail, so as to 0 clasp it closely and prevent the rail from flvspreading. By the use of differently-sized clamps O, rails of varying widths at their I eases can be employed.

It will be observed that while each bed- 3 5 plate E is provided with openings toreceivc bolts and fastening-clamps and means for sesmallest possible space.

What I claim as new is 1. The combination of arailroad-tie, A, bedplates E, set upon the upper surface of the tie, and provided with openings F and slots F, hollow beneath, and protected from entry of earth from the ground by the interposed tie beneath the hollow chamber thus formed, bolts D, and clamps O, the bolt-heads being adapted to be passed into said openings F, and into the protected hollow chamber beneath the slots F, whereby the bolts will project .up through the slots and clamp O, the whole being held in place by the nuts D, substantially as described.

2. The bed-plates E, having openings F and slots F, hollow beneath, and adapted to be clamped to the rail and secured to an underlying railroad-tie, said bed-plates being plain or free from projections on their upper and lower surfaces, whereby they can be packed closely and take up small space while being shipped in numbers from place to place, substantially as described.
