resides in the mm struction arrangement and coinlunatlon of parts set torih ill and n the scope of the appended fIn the drawings higure '1 is-a top plan not necessitate supersiruot'urcs which not only" add to the cost of the installation oi the appa1atus,.but which also form obstructions for vehicles or the like. while passing a Application filed August 29,

-tion .is adapted, to

'a suitable pit extremities formed with "connected to the boxing 7. disposed casings are connected through the over the said crossing. The improvement; contemplates a plurality of what maybe termed turn-tables, preferably four in number, the said tables asingle rail sectiornand the said rail secregister with angularly arranged rail sections. I a

When aicar is to be directed from one track to another the car is moved its wheels are arranged upon the track sections ,of the turn-tables, and the said tables,

" are rotated in unison.

Referring to the drawings in detail, the

numeral 1 designates a crossing for railway 7 1 cars. The crossing,

illustrated in the figuresof the drawings contemplates 'a plurality of musings Q,

the same being four in num her and having their bodies arranged-within road bed. The casings 2 have their upper plates 3, the same being each prefe 'ahly' of a circular forma iion, and each of the-said off-set plates is providedupon its upper face with an annug0 lar ring or flange 4. preferably annular in itszlower'wall 5 formed lug-(i. while ll The casing 2 is alsd cross section and has with a reduced open- 1e said lower wall extends a suitable. distance beyond the casing proper 35 to provide what may be termed a flange 6. This flange 6' is adaptedto rest upon a suitable boxing. 7, the said boxing having its upper wail provided with an opening 7' which registers with the opening 6 in the'bottom wall of the casing 2. The flange (5 of theeasing 2 as well as the top of the boxing 7 provided with registering openings, the said openings adapted to receive. securing cleiuents such as bolts 8 and nuts 9, whereby the flange as well as the casingis: securely- The oppositely medium of traclcsectious 10. These track sections are each formed. with enlarged webs 11, the upper faces of which, adjacent their longitudimilelges. being formed with a 'recess or channel 12. and the portion of the [tango providing! the said channels l2lare loruu-d with a plurality of openings 13, the

said openings registering with similar openingsprm'lded 1n the plates 3 beyond the annu: lar flange 4, and the registering openings areadapted to receive securing elements such as nuts ll and bolts 15. The opposlte ends 11a of the rail seetionslO have their flanges formed with transversely arnnged recesses being provided each with 60 until 5 or opening PIOYlClBd in the which is connected to the undenfme of the 16, the same providing shoulders which are adapted to snugly engage both the top and the outer faces of the annular flanges 4. It is ofcourse to be understood that the spaced intermediate rail sections 10 are arranged in' pairs, and each of the said pairs of rail sections are arranged at an angle to the opposite pairs so'that when the track sections 17 provided upon the turn-tables'18' are rotated through the medium of the said turntables, thecoacting rail sections 17 will be brought into proper register with either pairs of the intermediate rail sections 10, whereby the independently pivoted car wheels, which are adapted tovbe positioned upon the rail sections 17v will be directed to the tracks over which the car is to pass.

The turn-tables 18 each have their upper portions comprising a flattened annular member 19 which is adapted to rest upon the plate 3 of the casing 2 .within the annular tl-ange 4-ll'1ercot. It desired, and in some instancesit has been found preferable, the annular )nember 19 may have its under face formed lwith a suitable raceway within which may be positioned antifrictional balls or rollers 20, and the periphery of the said annular member 19 may be also formed with a similar raceway within which isarranged the antifrictional balls 21 which contact with the inner face of the annular-flange 4.'

The numeral 22 designates the cylindrical body of each of the turn-tables, the same being received within the annular casing 2, and the said body may have its lower face formedwvith araceway 23 which receives antitrictional ball bearings ll, the latter bearing upon. the bottom or lower face of he said CtlSlllQ' 2.

The numeral 25 desi mates a reduced 0 lindrical extension for the body 22, the said extension projectingthrough the openings 6 and 7" and within the l'ioxing 7. Surrounding the extension 25 and secured thereto in any desired manner is a washer 26,

the latter bearing upon the under face of the top of the said boxing, and the extension ZS is provided with an angular stem 27, the same adapted to receive the annular opening 28 provided in the turning pieces 29. The stem 27 may be, and preferably is provided with a threaded extension 30, the same receiving suitable securing nuts 31, and if desired the said extension may be further provided with an opening through which passes a. cotter pin 32, the same serving as, a means for preventing thelaceidontal removal of the nuts 31. 7.

Each of tho casings? is provided with an opening 33, am l,secured within the said opening is a short pipe section iietgiwhieh is sustained at its outer end by a yoke hanger 35- plate 3. The mcmberQQ is provided with a pair of spaced depressions 3(3e1therof \VlllCll largement and each of the pipe sections 34 is provided upon its inner portion with a head 34, while arranged between the said bead and collar is a helical spring The locking pin is adapted to engage with either of the depressed portions 36 of the member 2. downturned arm 35, and the said arm has its lowerextremity playing Within a slot 39 which 'is provided with an operating bar 39. The slot 39' is substantially U-shaped,

that is the oppositeends are arranged at angles to the Ina-"n portion of the said slot,

The locking pin is provided with a" and these angular portion's'tareadapted to a provide means whereby'the pin 37, may be retracted through one of the depressions 36 beforethe member 22 is revolved. The bar.

39 is furtherprovided with an elongated slot 39, the said slotfbeing'adapted to reeeive the oflset ends of a rod 50. *This rod 50 connects with the arm"29, 'a'nd'by rovidingthe bar with the said slot 39 it will be noted that the bar may be moved a sufficientdistance to permit of the pin 37 being withdrawn from one of the recesses 36' by the said bar 39 actuating the rod 50. The straightened portion of the slot'39"is of a length equaling the distance of travel of the member 22, or that of one fourth of the revolution of the said member, and when the second slot-J36 is brought into register with thcopening 33 the arm 35" of the pin "'37 will have reached the second inclined portion provided by the slot 39' which permits of the expansion of the spring 35 which forces the pin 37 within thesaidsecond depression 36.

'lhe numerals 40 designate the outer rail sections of the turntt.bles. These rail sections are arranged in pairs and aline with the right angularly arranged intern'uidiate rail stictions 10. The rail sections 40 have their base flanges enlarged as at 4'1, and their extremities formed with transversely arranged recesses 43, and the recessed portions 4 are adapted toengage with the annular llanges t ol the casings 2, while the enlarged portions of the rails 40 lie flatly upon the outer extremities of the plates 3. The enlarged flanges 41 are provided with openings, the said openings registering with similar openings formed in the outer extending portions of the plates and the said openings are adapted to receive suitable securing elements 4-4.

Each of the main tracks 45 have their inner extremities cut' away or otherwise formed with depress ons, the said depressed lea 'termediatei rail sections having enlarged base flanges secured to theoppositely arportions adapted to' engage with the extending portion of the rail sections 40, andthe main rails 45 may be secured to the rail sections 40 through the medium of the usual 'which; have ,-an' annular flange that surrounds the annular body, of the casing, in-

range'd casings and having their-ends de-' pressed to engagefthe flanges-of the oppositely arranged casings, outer rail sections also provided with enlarged base flanges and having their inner faces depressed and overlying the annular flanges'and also having their-base flanges connected with the plates (ii-the casing, main' rails having flanged pro'ectio'ns which underlie-the rail sections at which are connected therewith, a turntable I for each of the casings, each of-the turntables having a rail section, and 'means for rotating andlocking the turntables to brlng their rail sections into register with either of the angularly arranged main rails and the intermediate rails.

v 2. In a crossing, a cylindrical casing main rails and intermediate rails connected with the casing, a turntable mounted for rotation upon the casingand being provided with a rail which is adapted to'register with either of theangularl arranged main rails and their intermediate rails, said turntable having its body provided with a pa' n'or spacediopenings, the casing being provlded with aipe member, a spring actuated locking pin Within the "sleeve and adapted to engage With one ofthe depressions in thebodv 'of'theturntable, an op crating bar, a link connected with the turntable and arranged within the slot in the operating her, the locking pin having a downturned arm, the loching bar having an elongated longitudinally extending slot which has its ends arranged or disposed at opposite angles to the edges of the said V.
