Application filed November 22,1916. serial No". 132,728.

To all whom it ma concern:

Be it known that I, PETER ENGLISi-I'," a citizen of the United States, residinoatDetroit, county of Wayne, State of Michigan, have invented a certain new and useful Iinprovement in Railway Switches and Crossovers, and declare the following to be a 11111, clear, and exact description of the same, such as will enable others skilled in the art to'which it pertains-to make and. nsethe same, rejferencebeinjg had to the acconipanying drawings, winch-form a part 01 this specification.

This invention relates to switches cross ove'rs" and is designed todo' awaywith the feather-point in ithe' cross over new 1n comlnohuse'. It afl'ordsa rail-0t uniform width and weight" 011 all points alongthe etosso'ver.

This switch is arranged to be thrown: autoinatically by" the train, opened automatically;

The switch and cross over is especially adapted for'use on a monorail-road, but with a few modificationswouldbe adaptable for use on ad'ouble track.

I Thefeatures in detailwillap'pear in the description following.

Figural is a plan View showing the cross over in non-operative position.

Fig. 2 shows the cross over set to guide the train from one line to another.

Fig. 3 is a sideview partly in' section of an elevated monorail railway embodying my new switch and crossover.

Fig; 4 is a. vertical crosssectio'n of the same; p

Fig.'-5 is an enlargeddetail chiefly in side ele' vatibn of a part" ofthe-elevate'd monorail lshdwing detailedly' the operation of the switch-throit'ihg lever;

Fig. 6 is a fragmentary plan View showiiig the switch thrown to transfer" the train from onemain rail to another;

Thein'vent'ion in the accompanying drawin'gs'is shown as applied'to a monorail road.

Such a monorail road I have already made the sub} set ofanothe plantation at this i application. The exe tmn in co ection with the mantra-1 road w n he Salaam: to a make known its applicability te =two rail ifoad The meae air ro'ad is an. le em can-lea as: the posts ct aaczid is? sham.

comprising a pair of main monorails or lines I), b whichcan be used-Tor traflic in two directions orfor two linesof traffic in one directioni The rails b, b are theload supporting rails. while the over-head rails c, 0 serve to guide the car andkeep it from tipping, in a way which need not here-be explained but which may be learned by examination of my applicationNo. 24:341.

0? represents a permanent cross over section. 6, 6 represent shiftable cross over sections- Fig. 1 shows the cross over and switch in non-operative position. It will be noted that each of the shiftahle cross over sections 6 contains not only a section" goes out of registry with the main run of theraih and the cross over section comes in registry with both the main rail and also-withthepermanent cross over sec tion forming a suitable rail connecting" one mainrailwith the other main rail without the interposition of any teather-pointsor frogs.

The apparatus by whichthis shifting is accomplished comprises arock shaft f properly joui-naled in the'supports for therailway. Referring to Fig. 4, it will be seen that this rock shaft is provided with adepending rock 5 arm 9 thatconnects with the depending arm it attached to the right hand shiftable cross over section by means of a link i. It will also be seen that a similar arrangement of arms and links connect the left hand shiftable cross over section with the rock shaft. Therefore the rocking movement of the rock shaft will simultane-- ously' spread the cross over sections and simultaneously bring toward each other the cross over" sections;

Referring'to the over headrails shown'in Fig. 4, itwill beseen that precisely thesame arrangement of main rails, shift-able cross over sections, rock shaft, arms and links 1s of hoththeunderneath rails and the overhead rails; This-simultaneous rocking of d the roekshfa'fts is: acc'cmplished by the; con- 1 neetinglhna 3 which: is-bent that thanndele as shown in Fig. 4 to clear the cars atthe side.

The rocking of'the underneath rock'shaft f is automaticallyaccomplished by tripping the lever 76 (Fig. 5), which may be done by a depending arm and roller Z carried on the locomotive or the first car on the train. The armand roller Z striking the lever is when raised, depresses it as shown in Fig. 5. Referring to Fig. 6, it will be seen that this lever is is fulcrumed at m and its resistance arm n extends beyond the fulcrum point and connects with an arm on the rock arm f by means of a bifurcated link 0. Hence the downward movement of the lever is is converted to the upper movement of the resistance arm n, and thereby it rocks the rock shaft 7 counter-clockwise (as considered in Fig. 4) thereby spreading the cross over sections and establishing the cross over connection from one rail to another. Now referring to Fig. 3, it will be seen that there are trip levers on either end of the switch block. a When the right hand lever of Fig. 3 is thrown downby entry of the train from the right, the left hand lever of Fig. 3'is thrown up by reason of being con nected with the rock shaft on the opposite side of that member (Fig. 2). In its upward position, it is ready to be operated to again close the, switch, and consequently as the train passes out of the cross over zone it depresses this lever which rocks the rock shaft clockwise when considered as shown in F i 4:. This, therefore, pulls the shiftable cross over sections inwardly and restores the main line sections in registry with the two main line rails or lines.

It, of course, will be understood that if operation of the switch is not desired, all that is necessary is to keep the trip arm Z up so that it will not strike the trip lever is,

.and hence no operation of the switch will be had and the train will continue along the rail. It will be understood that a trip arm Z carried by the train may be carried on the forward end for tripping the switch-closing lever is and on the rear end for tripping the switch-opening lever is.

That I claim is: a

1. In a railway, the combination of two main lines and a cross over, the latter comprising two shiftable cross over sections in endwise relation each of which is provided with a cross over rail section and a main rail section and which are simultaneouslyshiftable in opposite directions to establish the crossover and to break the main lines or to make continuous the main lines and break. the crossover, substantially as described.

2. In a railway, the combination of two main lines, a permanent crossover section and a pair of shiftable cross over sections at ,copposite ends of the permanent crossover,

section which are shiftable simultaneously away from each other and outward and simultaneously toward each other and inward toestablish or disestablish the cross over.

3; In arailway, the combination of two main lines and a cross over and switch, the latter comprising a pair of shiftable cross over sections, a rock shaft running substantially parallel to the main lines, one cross over, section being on one side of the rock shaft and the othercross over section being on the other sideof the rock shaft, and connections between-each of the crossover sections and the rock shaft whereby rocking of the shaft will simultaneously spread the cross over sections to establish the cross over while rocking the rock shaft in the opposite directionwill simultaneously bringtlie cross over sections in to disestablish the cross over. l V

4. In a railway,the combinationof a pair of main lines and a cross over and switch,

the latter comprisinga pair of shiftable cross over sections, a rock e shaft running substantially parallel with the two main lines and connected .to opposed sides of the.

shiftable cross over sections which lie on opposite sides of it, and a trip device at the incoming end of the cross over zonefor rocking the rock arm to shift the, cross over sections and establish the cross oven-and a trip device at the outgoing end of the cross over zone for rocking the rock arm in a contrary direction to shift the cross over sections and disestablish the cross over. 7 7

' 5. In a railway, the combination of two main lines, a pair of shiftable crossover sections, each comprising a cross over rail section and a main line rail section, and a permanent cross over section lying between the shiftable cross over sections, whereby the shifting of the cross over sections may bring the cross over rail sections into registry with this permanent cross over section to establish the cross over and into registry with the main rails todisestablish the cross over.

6. In a railway, the combination of a pair to disestablisha cross over, and automatic means operated by apassing train for both shifting the cross over, sections to establish the cross over and shifting the cross over sections to disestablish thecross over;

7, In a railway, the combination of two 'main lines, a cross over, the latter comprisng a pair of shiftable crossover sections which may be simultaneously shifted to establish the cross over and simultaneously shifted to disestablishthe cross over, and a switch, the latter comprising a rock shaft running substantially parallel to the two main fllinesg and,orroneside of which one shiftable cross over lies and on the other side i aaasoo of which the other shiftable cross over section lies, connections between the rock shaft and the two shiftable cross overs so that the cross overs are simultaneously caused to spread or come toward each other, a trip lever located at one end of the rock shaft for rocking the shaft in a direction to spread the shiftable cross over sections as the train comes into the cross over zone, and a second trip lever located at the opposite end of the rock shaft to rock the same in a contrary direction to bring the shiftable cross over sections toward each other and disestablish the cross over when the train passes out of the cross over zone.

8. In a railway, the combination of a pair of underneath main lines, a pair of overhead main lines, a cross over for the underneath lines, a cross over for the over-head lines, each of the cross overs having sections arranged to shift to open or close the cross over, and means for simultaneously and automatically operating the underneath and the over-head cross over sections from the train.

9. In a railway, the combination of two underneath main lines, two over-head main lines, a cross over for the over-head lines, a cross over for the underneath lines, each of the cross overs comprising shifting parts shiftable to establish or disestablish the cross over, and means for simultaneously operating the shifting parts to establish or disestablish the cross over of the over-head and the underneath lines simultaneously, comprising a pair of rock shafts having suitable connections to the shifting cross over sections and a link connecting the rock shafts.

In testimony whereof, I sign this specification.
