RAILROAD-CROSSING.

Patented Nov. 13, 19062 Application led June 7,1906. Serial No. 320.596.

To all whom t may concern:

Be it known that I, HORACE A. BAKER, a citizen of the United States, residing at Pecan Gap, in-the county of Delta and State of Texas, have invented certain new and useful Improvements in Railroad-Crossings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to Which it appertains to make and use the same.

My invention relates to improvements in railroad-crossings, and more particularly to a derailing mechanism, by means of which liability of collision will be reduced to a minimum.

The object of the invention is to provide a derailing mechanism of this character which will be of simple and comparatively inexpensive construction and veryeifective 1n operation.

With the above and other objects in view the invention consists in the construction, combination, and arrangement of devices hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a plan view of a railway-crossing having my improved derailing mechanism applied there- 'to. Fi 2 is a detail view, on an enlarged scale, o one of the derailing devices and its connected parts. Fig. 3 is a longitudinal sectional view taken on the lane indicated by the line 3 3 in Fig. 2. 4 is a detail sectional view taken on the ane indicated by the line 4 4 in Fig. 2, and Fig. 5 is a detail sectional view taken on the plane indicated by the line 5 5in Fig, 1.

Referring to the drawings by numerals, 1 and 2 denote two intersecting railroad-tracks upon which my im roved derailing mechanism is mounted. his mechanism comprises four derailing-blocks or devices 3, located at suitable distances from the intersection of the track-rails, and one being provided for each of the four branches of the crossin Each of the derailing blocks 3 is carried xClhy a transversely-sliding bar 4, which has its opposite ends connected by links 5 to angle-levers, bell-cranks, or the like 6, which are mounted upon vertical pivots 7, located upon the opposite sides of the tracks. Mounted in suitable bearings ad'acent to the sliding bar 4 upon each of the ranches of the intersecting tracks 2 are transversely-extending shafts 8,

which have upon their projecting ends wheels or thelike 9. Each of the shafts Sis rocked or oscillated by means of a push-b ar 10, located upon one side ofr one of the track-rails "and adapted to be depressed by the flanges'of the4 wheels of a car or trainpassing over the same.

Each of these bars has one of its ends pivotally' connected to a crank-arm 11 upon the adjad cent shaft 8 and its other end pivotally con' nected to a similar cranksarm 12, suitably mounted u on one of the cross-ties or upon onef of the trac rails The crank-arms are equal in length, so that the bar 10 will be maintained in a horizontal plane asv it swings vertically. Suitable springs 13 are provided for mai-nw taining the bars 10 in their elevated positions,

so that when the flanges of the car-wheels strike their rounded ends they will be forced -downwardly against the tension of said springs to rock the shafts 8 and partiallyro -1 tate the Wheels; 9. Each of the wheels 9 is connectedby a cable or other flexible-connection 14 to one of the rotary disks 6 uon the-- adjacent side of one of the branches o the intersecting track, so-that when. the shaft 8 upon one Abranch of one of the tracks is actuated its motion will be imparted through s aid connecting-cables to the two rotary disks.

upon the adjacent sides ofthe two branches of the other or intersecting track, in order that the two disks thus actuated will shift the derailing-blocks, which they control, from an inoperative to an operative position. Thus as a car or train approaches a crossin upon one of the tracks and actuates the ar 10 upon that branch of said track the tWo derailing blocks upon the branches of the other or intersecting. track will be moved from an inoperative to an operative position in order that trains approaching the crossing in either direction upon the last-mentioned or intersecting track will be derailed before they reach the crossing.

' Each of the cables 14 has one of its ends secured to and wound upon one of the wheels 9 corners of the crossing, and they are protect- IOO I .intersecting track to'be moved into an operative position, so that a train or trains u on said intersecting track will be derailed be ore reaching the crossing.

Any suitable electric or other si naling device may be used in connection-with this de- `railing mechanism, so .that engineers upon approaching trains will be warned of the danger ahead before they reach the derailing devices.

Various changes in the form, proportion, and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of the invention as defined by the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1.- The combination of intersecting tracks, a transverselyamovable bar on one of said tracks at a distance from the crossing andhaving a derailing-block, a rotary element mounted near said bar and connected thereto, a rock-shaft mounted on the other track at a distance from the crossing and having awheel and a crank-arm, anoperating connecting element between said wheel and the said rotary element to actuate the latter and the said bar and derailing-block, and a train-operated push-bar connected to the said crank to operate the same, for the purpose set forth.

2. The combination with intersecting tracks, of transversely-movable bars located u on the branches of said`tracks, derailingb ocks carried by said bars and movable toward and from the rails of said tracks, rock shafts located in the branches of said intersecting tracks, a train-operated device upon each branch of said intersecting tracks, each of said devices actuating the adjacent rockshaft, rotary elements for actuating said derailing-block-carrying bars, and connections between said elements and said rock-shafts, substantially as described.

3. The combination with tracks, of transversel -slidable bars upon the branches of said trac s, derailing-blocks carried by said bars and movable toward and from the rails of said tracks, rotary elements forzactuating said sliding -bars, rock-shafts located in the branches of said tracks, ushbars located adjacent to the rails o the branches of said tracks for operation by the car-Wheels of passing trains, connections between said bars and said rock-shafts, guides, and flexible connections engaged with said guides and connected to said rock-shafts and said rotary elements, substantially as shown and described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

intersecting HORACE A. BAKER.
