RAILROAD-CROSSING.

Specification of Letters Iatent.

Application filed October 12, 1911. Serial No. 654,423.

To all whom it may concern:

Be it known that F, Losn O. HARBAUGH, a citizen of the United States, residing at Piqua, in the county of Miami andState of Ohio, have invented certain new and useful Improvements in Railroad-Crossings, and

l I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to railroad crossings, and has for its purpose to provide an arrangement of tracks whereby a car or 'train may be successfully passed thereover without the usual bumping or jarring incident to having the track ends separate, as is now the case with the type of crossings employed.

The invention further proposes a construction whereby the tracks of one of the lines are uninterrupted at the crossing, and

wherein a means is automatically actuated by the cars of the other line to provide a similar unbroken wa for said line.

-With these and otiier objects in view the invention'consists in the novel details of construction and combinations of parts more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a partof this specification in which like numerals designate like parts in all the views :Figure 1 is a top plan view ofa railroad crossing employing my invention. Fig. 2 is a side elevational view, partly in section, and on a reduced scale, showing the crossing arrangement. Fig. 3 is a transverse sectional view of the movable track section. Fig. 4 is a detail view showing the manner of supporting the ends of the movable track section, Fig. 5 is a top plan view, partly broken away, of one of the track shifter'actuating devices. Fig. 6 is a trans-- verse sectional view of Fig. 5 taken on the line 66 and looking in the direction of the arrows. Fig. 7 a top lan view, artly broken away, of the track shifting evice. Fig. 3 is a transverse sectional view of Fig. 7 taken on the line 8-8 and looking in the ,from position, comprises. an actuatin vice that is connected therewith throug tlie naked in the plate 17 (see .Fig. 8

direction of the arrows, and Fig. 9 is a de tail perspective view of the track shifter actuating device carried by the car.

Referring to the construction in detail A designates the main line whose tracks are designed to be continuous and unbroken at .the place of crossing, and B designates the tracks of the crossing line whose rails are adapted to be temporarily made'continuous through the medium of the apparatus herein disclosed. The rail ends of the tracks B atthe place of crossing are ada ted to be connected through the medium 0 a pair of track sections 1, whose ends 2 are adapted to be brought into close engagement with the ends of the tracks B. To this end said track sections 1 have their web and flan e portions 3 and 4 cutaway, whereby the en s 2 may be readily moved over and be supported upon the rails of the track A. The bed of the rails A is located sufliciently below the bed of the rails B to enable the track ends 2 being swung over or clear of the rails A, as illustrated in Figs. 1, 2 and 4. The track sections 1 are each mountedon a pivot 5, within raised bearing portions 6 a pair of links 8 that are nected at 9 adjacent the trac ends 2, said track sections 1 are designed to bemoved in unison. The links 8 are connected at 10 by a lever 11, which is in turn pivotally sepivotally concured centrally of the bed plate 7 by a bolt or stud '12.

The means for swinging the track secof a bed plate 7 and through the medium of tions 1 on their respective pivots to and medium of a rod 13 and a pair of 'angularly disposed links 14. The actuating device comprises a quadrant head 15 fulcrumed at 16 to a supporting plate 17, which is suitably mounted on a pair of ties of the rails B, as indicated in Fig. 1. The quadcrank 21. The'pinioii 19 is designed to be rotated to actuate the crank 21 for moving I. the rod 13, through the medium ofits earing connectionw ththe quadrant hea .15. Thehcad=f15 is designed to be oscillated through themedium of a lever. 22 that is pivotally connected therewith at the point 23. Sa-id lever 22 is connected with a pair of rods 24 and 25 at the points 26 and 27 respectivelyffiand through which rods the lever is actuated, with .eitherof the pivots 26 and .27 serving as the fulcrum. 'The' rods 24 and 25 are designed to be actuated through the medium of suitable devices 10- eated toleither side of the crossing through the -agency' of the ca-r. Each of said actuating devices consists'of a table 28 (see Figs. '5 and 6)' journal.ed in a supporting plate 29 on ashaft30, and said shaft 30 has ke ed "thereon a disk 31. The disk 31 is notche at diametrically opposite points 32 to receive rollers 33 of a pair of'detents', and through 1 the-medium oflwhi'ch' the rotatable tableis nomally held in the passing car. "an arm 34'pivoted at one end 35 to the base plate29, and both of the arms 34 areconosition to be actuated b aid detents comprise eac nected by a spiral spring 36 which 'ves the desired play to said arms. The ta 1e 28 is designed tobe directly actuated by a device carried-on the' car through the medium of a two-armed lever '37 which carries at the ends of said arms two studs 38, that project through suitable apertures 39 out in the periphery of the table 28 at diametrically op'p'losite points. The leverv 37 is mounted to ave turning movement onthe shaft 30 whereby to rotate with the'table 28, and in addition thereto the aperture 40 of the lever 37. is slightly'elongated or of substantially' elliptical design as indicated in Fi s. 5 and 6. The studs 38 areadapted to engaged for actuating the table 28 through the medium of the track shifting device carried by the car, and to the end of taking up orfavoiding any jarring oi: the lever37, in-

v I cident tos'uch engagement, said lever is de-.

si ed tohave' lengthwise movement relatively to the shaft 30 thr ugh the medium ofthe elongated opening 0, above referred, to. It will be noted that thelengthwise di- 'mensions of the openings 39 are such as will allow jo'f this movement.

I The rotating inoveinent'of the disk 31 is imparted to the rod24 through the medium of a link 41,

which conhectswithsaid rod by 'j a bell crank lever 42 that is journaledin suitable bear 'irig member's'43.' The actuating device} carried by the car which" engagesvviththe'studs 38 consists in a plate" 44 provided wltha camqgroove or channel-45 whose: ends are 'flared out- I wardlyf 2. In a railroad crossin inseam turn the bell crank lever 42 and said latter movement is imparted to actuate the quadrant head- 15 through the medium of the lever androd connections 22- and 24. In this operation, the pivot pin 26 serves as the fulcrum for the lever 22 (see Fig. 1). {and causes the lever '22 and head 15 to take substantiall those positions indicated b broken ines. The movement of the hea l causes the pinion 19 to be rotated, and this operation, through the connections 13 and 14, turns the track sections 1 from the position shown in Fig. 1 to the dotted line position in said view, when the rails of the track B are made continuous. As the train or car passes over the crossing, the actuating member 44 engages with the nearest I stud 38 on the other track actuating device and causes an operation similar to'that just described, and whereby the track sections 1 are restored to normal. It will be noted that both of the turn-tables 28 and the pinion19 are allrotated a half revolution at each-and every operation, thus insurin all operative parts being, atall times, at a ead center and in proper position to be operated by a moving-car. 4
