CALVIN W. BAGBY, OF OREGON CITY, OREGON.

RAILWAY-TRACK CONSTRUCTION.

Application filed March 25, 1916.

To all whom it may concern:

Be it known that I, CALVIN W. BAGBY, a citizen of the United States, residing at Oregon City, in the county of Clackamas.

and State of Oregon, have invented new and useful Improvements in Railway-Track Constructions, of which the following is a specification.

This invention relates to improvements in railway track construction and has particular application toa track crossing structure.

In carrying out the present invention, it is my purpose to provide a railway track crossing for use at the intersection of two lines of trackway, which will be constructed in such manner that the lines of rails of each trackway, at the crossing, may be made continuous or unbroken so as to prevent jarring of the cars passing over the crossing and wherein the lines of rails of one trackway may be opened up and the lines of rails of the other trackway closed simultaneously so as to enable a car on the last-mentioned trackway to cross the other track and to present continuous traction surfaces to such car.

It is also my purpose to provide apparatus of the class described which may be 0perated quickly and conveniently by the person in charge of the crossing and wherein the component parts will be so arranged and correlated as to reduce the possibility of derangement to a minimum and enable access to be readily had to such parts in the event of the latter becoming broken or in need of cleaning.

With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims.

In the accompanying drawings, Figure l is a top plan view of a track crossing constructed in accordance with my present invention, the parts being shown in one position. Fig. 2 is a similar view showing the parts in the other position. Fig. 3 is a sectional view through the crossing. Fig. 4 is a similar view taken at right angles to Fig, 3. Figs. 5 and 6 are detail views of the rail section.

Referring now to the drawings in detail, 1, 1 designate the lines of rails of one trackway, while 2, 2 indicate the lines of rails of another trackway intersecting the lines of rails 1, 1. The portions of the lines of rails Specification of Letters Patent.

1 immediately adjacent to the lines of rails 2 and between such lines of rails are bowed outwardly as at 3, while the portions of the lines of rails 2 between the lines of rails 1 are olfset outwardly from the portions of the rails 2 at the opposite sides of the rails 1, as clearly illustrated in Figs. 1 and 2 of the drawings. Fixed to the inner surfaces of the respective portions of the lines of rails 1 between the lines of rails 2 are rail sections 4, while lying in face to face contact with the inner surfaces of the bowed portionsof the lines of rails 1 at opposite sides of the crossing are point-sections 5 respectively having the point ends disposed adj acent to the outer ends of the bowed portions and the butt ends terminating in juxtaposition to the ends of the rail sections 4. The point rails 5 form continuations of the straight portions of the rails 1 at the bowed portions of such rails and these point rails are capable of sliding movement and in one position thereof the butt ends lie flush with the inner surfaces of the lines of rails 2 and are spaced apart from the adjacent ends of the rail sections 4 so as to open up the trackwayv 2 in order that cars on'such trackway may pass the crossing. In the other position of the point rails 5, the butt ends thereof engage the ends of the rail sections 4 so as to close the trackway 2 and form continuous traction surfaces over the crossing for cars on the rails 1. Placed in face to face 7 outer ends thereof are spaced apart from the point sections 5 and lie flush with the offset portions of the lines of rails 2, while when the sub-sections are moved outwardly the outer ends thereof abut the point rails 5 and act to form an uninterrupted traction surface for cars passing the crossing on the lines of rails 2. These rail sections 6 are disposed in alinement with the main portions of the lines of rails 2 and form, in effect, continuations thereof so that the cars may pass over the crossing. The crowned edges 9 of the subsections of the rail sections 6 enable the trucks of the cars to pass the crossing without jarring or rattling, thereby compensating for the breaks in the rail sections 6 due to the spreading of the sub-sections to close the crossing for cars on the lines of rails 2.

The point sections 5 and the sub-sections of the rail sections 6 are secured to the respective portions of the lines of rails 1 and V cars traversing the lines of rails 1 may pass over the crossing without shock or jar, while when the butt ends of the point sections 5 are spaced apart from the juxtaposed ends of the rail sections 4, the sub-sections 7 of the rail sections 6 are adapted to be.

moved outwardly so as to form continuous traction surfaces for cars traversing the lines of rails 2.

In order that the point rails 5 may be moved to open position and the sub-sections of the rail sections 6 moved to closed position simultaneously, and conversely, the point sections 5 move to closed position and the sub-sections 7 to open position, the following mechanism is employed: Extending transversely of the lines of rails 2 is a cross bar 9 having the opposite ends thereof secured to corresponding sub-sections 7, while disposed in a plane below that of the bar 9 and arranged transversely of the lines of railsv 2 is another cross bar 10 having the opposite ends thereof fastened to the remaining sub-sections 7. Extending longitudinally of the lines of rails 2 and between such rails is an operating bar 11 having one end secured to the cross bar 9 and the opposite end connected through the medium of a link 12 with one leg of a bell crank lever 13 fulcrumed between the lines of rails'2, while disposed below the bar 11 and extending longitudinally of thelines of rails 2 is an operating bar it having one end connected to the cross bar 10 and the remaining end connected through the medium of a link 15 with one leg of a bell crank lever 16. The other leg of the bell crank lever 16 is connected to the remaining leg of the bell crank lever 13 by means of a link 17 and also pivotally connected to the outer end of the link 15 is one end of a link 18. The other end of the link 18 is pivotally secured to one leg of a bell crank lever 19 and the other le 'of the lever 19 is connected with one end of an operating rod 20 under the control of the person in charge of the crossing. Secured to the bar 11 and proj ecting upwardly therefrom is apin 21 and fulcrumed upon a plate 22 extending transversely of the lines of rails 2, 2 are bell crank levers 23 and 24 disposed at the opposide sides of the bars 11 and 14;. The corresponding legs of the bell crank levers 23 and 24: are interconnected by means of a link 25 lying upon the operating bar 11 and formed with a cross slot 26 that receives the pin 21.' The remaining leg of the bell crank lever 23 is connected through the medium of so a link2? with one end of a rod 28 projecting through alining slots formed in the overlapping ends of the sub-sections 7 of the rail sections 6 upon one side of the trackway formed of the lines of rails 2 and through an opening formed in the adjacent portion of one line of rails 2, while the remaining leg of the bell crank lever 24: is connectedthrough the medium of a link 29 with one end of a rod 30 projecting through alining slots formed in the overlapping ends of the sub-sections of the other rail sections 6 and through an opening in the adjacent portion of the other line of rails 2. The outer ends of the rods 28 and 30 respec tively are connected with cross bars 31 arranged transversely of the lines of rails 1 and having the opposite ends thereof connected to the corresponding point sections 5. In the present instance, the corresponding point sections 5 at each side of the point of intersection of the trackways .are also interconnected by means of a cross bar 32 and the cross bar 32 is connected by means of braces 33 with the cross bar 31 and with the rod 28 or 30. In th epresent instance, guard rail sections 34: are disposed at the point of intersection of the trackways be tween the lines of rails 2 and spaced apart from such lines of rails, while guard rails 35 are disposed parallel with the lines of rails 1 between the latter and the ends of the guard rail'sections 34 are connected to corresponding ends of the guard rails 35, while the guard rails 34C are formed with slots and openings to accommodate the cross bars 9 and 10 and the rods 28 and 30, as clearly illustrated in Figs. 3 and a of the drawings. Underlying the bases of the rails at the points of intersection thereof are plates 36 which, in the present instance, are parallel with the lines of rails 2 and to these plates 36 are fastened the ends of the supporting plate 22. At the points of intersection of the rails, the latter are suitably connected together by means of angular brace arms 37 and bolts 38, while guard rails 39 are arranged at appropriate places upon each trackway to protect the wheels of the trucks approaching the crossing.

In practice, when the rod 20 is moved in one direction, the bell crank lever 19 is swung from the position shown in Fig. 1 to the position shown in Fig. 2 and in this movement of the bell crank lever 19, the operating bar M is actuated to draw the subsections 7 connected thereto inwardly, while the bell crank lever 16, the link 17 and the bell crank lever 18 slides the operating bar 11 in the opposite direction to move the subsections 7 connected thereto inwardly. Simultaneously with the movement of the operating bar 11, motion is transmitted to the bell crank levers 23 and 21 with the effect to pull the rods 28 and 30 inwardly toward the center of the crossing and in this movement of the rods 28 and 30 motion is transmitted to the point sections 5 to move the latter to closed position, thereby closing the track formed of the lines of rails 2 and opening the trackway formed of the lines of rails 1 so that traflic over the lines of rails 1 may pass the crossing without shock or jar. When the direction of the rod 20 is reversed, the sub-sections are moved outwardly, while the point sections 5 are actuated to open the trackway formed of the lines of rails l and in this position of the sub-sections and the point sections, traifio may pass the crossing over the lines of rails 2 without subjecting the cars to shock or jar.

IVhile I have herein shown and described the preferred forms of my invention by way of illustration, I wish it to be understood that I do not limit or con-fine myself to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims and without departing from the spirit of the invention.

I claim:
