T 0 all whom it may concern:

have right angular extensions as ind' :ated

Be it known that we, Lnwrs ALEXANDER as at 3; or in fact the entire plate, it of andv SAMUEL l1. GANO, citizens of the United States, and residents of Ulinton,in the county of Dewitt and State of lllinois, have invented certain new and useful Improvements in Railway-Crossings, of which the following is a specification. V

This invention relates to railways, and more especially to the crossings thereof; and the main object of the same is to produce a device of this kind applicable to cases in which the tracks cross each other at any angle, while the invention also contemplates ,the production of a weather proof construction and one in which the rails of the track in'use are automatically made continuous so to lessen jar and noise and to avoid deraihnent.

T o these-ends the invention consists primarily in a base plate provided witha peculiararrangenient of slots, and rail-carrying tumblers journal'ed in tour independent bearings adapted to be separately bolted to said plate according to the angle of the crossing; and it consists secondarily in the peculiar construction of theturnbl'ers and theirsupports, and in the means for turning the1nall as hereinafter more fully described and claimed, and as shown in the drawings formin a part of this specification and in Which-- i ure 1 is a general plan view of this crossing with certain parts at the different corners thereof removed or in section to illustrate the construction of the parts beneath. Fig. 2 is a perspective view of one. bearing with its tumbler withdrawn and lace. Fi 3 is a bottorn p an thereof. Fig. 4 is a detail of one of the angular fish plates.

In the drawings the arts are broadly designated by reterenee letters as follows: P designates the base plate, E the bean ings, T the tumblers, O the operating mechanism therefor, and it the rails. The ties for supporting the latter and the base plate, and specific construction of the operating mechanisin'iurther than as necessary to an understanding of this invention, are not illustrated.

The base plate P is by reference a single rectangular sheet of meta either solid or in skeleton form, supported on ties or otherwise &S IIMLTZ .l)6 found desirable, and provided through its body at proper points with a series of transverse slots 1 and asericaof oblique slots 2, either or both of which m'iiy forming no part of the invention.

skeleton form, can be provided near its l'our corners with several series of slots so located and arranged as to'permit the carrying out of the idea set. forth below. While this plate is shown as flat (as that portion of it which forms part of the crossing will be), it is not inconsistent with or material to this invention that at other points on its surhu'e, as near its edges, it could he provided with means for bolting or clamping it to the eight rails which constitute the crossing or to the ties.

The bearings B are duplicates of (ltll other, and a description of one will sullice for all. llarh comprises a preferably rec tangular body ll) pierced near its corners with. holes H, and tour bolts 12 which take through the slots in the base plate and whose nuts preferably stand at their upper ends so that they can he readilyreached, and if desired may he held by nut locks These bodies are shown as superimposed upon the base plate, as they will be if the rails lie above its upper surface as in our preferred c nstruction. By the use of transverse sets ofslots 1 and oblique sets of, slots 2 arranged in alternating series around the base plate, it is-obvious that the bearings can be connected therewith at various oints, nearer to or further from each other in pairs to accommodate narrow gage tracks or standard gage tracks, and in right-angular or oblique angular position with respect to each other to accommodate riglitengular crossings or those of acute or obtuse angles. The body otthe bearing is preferably formed with a raised, annular boss 14 surrounding I a central upright hole 15 through the hearing and hating its upper end conical sothat it slopes outward ar'd will prevent water from passiu'ti, througlh the hole; and ooening l6 r'ltr eferably parallel with one side or go of the body g through it and intersects one edge 01" am ltole terireceptiori of the rack bar which forms ing mechanism. lit the ody rests l at on the base late, this opening is preferably made in t e form of a groove in its lower face as seen in art of the o erat- The tumbler for each bearing has an upright cylindrical body 200i a'si ze to fit c osely'but IfQtatably in the hole -15, a gear OI' EJiDlOQ 21 oppos te-said opening 16' and ierein.

formed. by cutting teeth in said body, and an enlarged head 22 formed with its under lace slightly dished to lit the conical upper end of the boss It so. as to shed water. Said head ma also be provided with an annular llange 25} to receive a trey to prevent its dislodgemmrt, if desired. Superimposed upon and preferably cast with said head is a short rail section 25 which may be tempered if desired, this section being ot a length to bridge thebreak in each ol the rails forming parts of the tracks which cross each-other.

'lhc rails it are of the usual coustrtwtion, suitably supported on. ties not shown, and also connected with and supported by the tate if desired. though not so illustrated l Their adjacent ends 30 pret'erably lie ltat on the bodies Idol the hearings and abut against the boss which by preference is a tritte larger in diameter than the head of its tumbler, and hence when the rails expand they may press against the boss but will not interfere with the rotation of the tumbler amt its head. Adjacent. ails are by )refcrence connected on. tlieir outer sides by angular tish plates 31 whose angles are 'of such shape that, when in place they engage the ltanges 23 and term keys, and each checks the rotation of its adjacent; tumbler "when it has been turned so that the short rail section 25,thereon stands inline with either pair of adjacent rail sections 30. Said short section is of course made of sutlieient length to allow clearance for the flange of the wheel when a train runs over the crossing.

'lhe'operating mechanism which forms a part oi this invention comprises two parallel rods -10 extending through the openings to in the l'itarrings amt having teeth 4.1 at proper poin s to engage'the pinions on the tumblers so that all ol" the latter will be turned simuttaneotisly when the rods are moved in the proper direction. in Fig. l we have shown these rods as engaging the inner sides of two' pairs ot' tumblers, and hence as connected by a link 42 so that they shall move oppositely and simultar-ieously. But it is obvious that it both rods lead to the right of all the tumblers the rods would have 'to move in unison to turn all the tumblers in unison. This would be satisl'actory where the crossing is a right angular one and all tumblers must be turned through a quarter circle, but in the illustration where the crossing is an oblique one the tumblers are by prelerenmturned through an are bounded by the smallest angle at each point ot crossing and the angular lislr-ptales are located in--the are bounded by the largest angle. As herein illustrated, the link 42 has an arm -13 connectedas at it with the rod that governs derailing at an interlocking plant. Movement ol' the arurwill swing the linlt, and the latter will move the rods simultaneously and turn all the ttn'ublers through I l l l l l l l ,E ffsT mamas cow 853,693

considered necessal to illustrate how the;

opposite ends of the rods could be similarly? operated, and it isquite within the province of our invention that another pair of rods and operating meehatiisms could be arranged I on the other track with similar results.
