RAILROAD-CROSSING.

SPECIFICATION forming part of Letters Patent N o. 376,756. dated January 24, 1888.r

' Application filed September 30,1887.y Serial Nr 251,143. (No model.)

To all whom it may concern: Be it known that we, WILLIAM H. SHAN- Non and ROBERT T. SHANNN, citizens of the United States, residing at Stockton, in the county of San J oaquin, State of California, have invented certain new vand useful Improvements in Railroad-Crossings, of which the following is a specification, reference being had therein to the accompanying drawings, in which-- f Figure lis a plan view of a railroadcrossing, showing our invention. Fig. 2 is a section of the same through line x w, Fig. 1, and applies to any equivalent position of Fig. 1. Fig. 3 is a section through line z z, Fig. 1, and applies to any equivalent position of Fig. l. Fig. 4 is a perspective of one of the bed-plates. Fig. 5 is a perspective of an angular connecting-plate. Fig. 6 is a'perspective of a bench connecting-plate. l f

The object of our invention is to render the removing o'f broken and worn rails of railwaycrossings andy replacing of suchwith sound rails more expeditious and less expensive than the methods nowin vogue. This we accomplish by connecting the wearing-ways to the bed-timbers by means of bed-plates and such needful devices for rendering. such connectionsable to'bear greatstrain, as will be hereinafter described, and pointed out in the claims. j l

The trackways may run toward each other at a right or any other suitable angle. In the drawings we have represented the trackways crossing at an exact right angle. l

In order to more particularly designate each way, let B and B represent the bed-timbers of one way, and B2 and B3 the bedtimbers of the other way, such timbers resting upon the roadbed. f f f A represents the ordinary ties of the continuous railway. A bed-plate, C, is secured to the timber B, and is in its position the equivalent of the bed-plateG in its .position and of the plates Cz and C3 in their respective positions, there being a groove or channel in the plates C2 and G3 where they are inter-v sected by the plates C and C. These plates are all provided with vertical flanges for the purpose of attaching, by bolts, the wearing ways or shoes thereto, which are designated as D yD D2 D3, the seriesv of outside shoes, andV E E F.2 E3 as one set of inside shoes, and F F F2 F3 as a second set of inside shoes, acting coordinately with .the E series. vThe Dseriesof shoes form the outside corners and are angular, while the E and F series form the inside rcorners and comprise two sides and the front of a rectangle, the front only being employed as a wearing-surface. I

G represents a bench-shaped4 plate, and is.

to the outside of the D series of shoes, to 'stiffen the same and to secure greater rigidity to-resist the necessary heavy pressure of passing .7o

trains. The same series of bolts secure the shoes of theE and'Fseries and the plates G to the flanges of the plates C C C2 G3. The same series of bolts secure the shoes of the D series l Y and the plate H to the flanges of the plates C C' C2 C3. A clamp, a, is attached at the connection of each of the shoes of the E and F se'- Y 'ries to the plates CC C2 C3, its lip overlapping the lower edges of the shoes, thus forming a firm joint. I g y A small plate, c, having a bottom lng, is secnred, one each, to the bed-plates C CG? C3 at the points of all the angles of the different series of shoes, and impinges uponV their lower fitting into the in-terstices formed by the lower edges of the shoes opposite to each other.

ledges to prevent possible spreading, the lug It will readily be seen that the above-def scribed method of constructing a railroadcrossing is suiiciently substantial for constant use, andf at the same time admits of detaching the broken and worn shoe-rails from the bedplate, &c., by simply removing a few bolts.

Having thus described our invention, what we claim therein is 1. In combinationwitn the bed-timbers B,

ached to the bed-timbers and provided with mo flanges, the shoes E F and the clamps ce, such clamps being,` secured to the bed-plates and overlapping the lower edges ofthe shoes7 substantially as described.

3. The combination7 with the bed-plates secured to the bed-timbers,of the shoes E F and angular plates G, substantially as shown.

4. The combination, with the bed-plates G and shoes D and E, and equivalent points thereto, of the bracingplates c, secured to the plates C and provided with lugs iitting into the interstices between the shoes D and E and impinging upon the lower edges of said shoes at the points of their angles, substantially as Shown.

5. The combination, substantially as shown, of the bed-timbers B, the plates C, the shoes D, and the angular plate H.

6. The combination, substantially as described, of the timbers B and B2 at right augles, the iianged plates C and C2 at like right angles, the plate C2 being provided with groove or channel at its intersection withplate G, the shoes D and E, securedY to the flanges of the plates C and C2, the angular plate H, attached to the shoe D,v and the lug-plate c, attached to the plate C.

7. rlwo traekways running toward eachother at a right angle and composed of the bed-timbers B B B2 B, the relative bed-plates C C CE C, provided with flanges and secured to said bedtimbers, the series of angular shoes D D DL D, E E E2 E3, and F F F2 F3, such shoes being,r secured to the ianges of the bed-plate by removable bolts, the plates G H a, and lug c, all substantially as shown.

In testimony whereof we afx our signatures in presence of two witnesses.
