provide aswitch device'for mono-railitracks which is of ,simple,`durable and eicientconstruction and which-is capable-.of being operated to arbitrarily direct a mono-rail carl from a main track to any one ofv a plurality of branch tracks. v f, vrs.;

Although I .will describe only one form of switch device embodying my invention,

and will point out the novel features thereof in claims, it is to be understood that various changes and modifications may` be `made without departing from the spirit of the invention and the spirit and scope of the ap ended claims.

n the accompanying drawings,

Figure 1 1s a view showing in top plan i one form of switch device embodying my invention in applied position with respect to a plurality of mono-rail tracks;

Figure 2 is a vertical sectional view taken on the line 2-2 of Figure 1.

.Referring specifically to the drawings, in which similar reference characters refer to similar parts, my invention, in its present embodiment lcomprises a carriage made up of a plurality of beams or bars 15 rigidly connected in spaced parallelism by means of a supporting structurel for mono-rail tracks, and provided with a plurality of grooved wheels 16 mounted for movement over rails 17l connected at their ends to'posts 18. In the present instance, the intermediate portion of the carriage is provided with two beams 15 between whichI are arranged the grooved wheels 16, while the end portions of the carriage are constructed with single beams with the wheels 16 disposed at the outer sides of the beams. Certain of the wheels 16 are connected by a drive shaft 19, such shaft being journaled in the beams and operatively connected to a motor 20 through thecfasprocketiandchain l' I I connection 21, as clearly' shown in Figure2., `As previously I; mentioned, i 1; the several beams of the `carriage areirigidly'connected to? each other .through the medium of mono.-

tracknsections, lwith".any-'numbery of track'4 sections sustainedf `upon .-thefscarriage, 1 de v pending i upon the fparticular use to which.

. thefswitch.: device is adapted to :be put. r-In-A so i `rail tracks; yandcthes'e tracks .areinfreality v the presentiinstance, Iiihaveshownthe car--` J riage as supporting a curved trackisectiony 22and a linearer straighttrack' section 23.l In=fboth n instances, the f `track sections and their 4supporting?uneans 'are constructediin accordance with thefmon'oerailwtrack rein bodiedninflmy1copeningapplicationhereinf before?referredjtof'V Thesw-itchdevice'isadapted for directing a; mon'oraill'ylcarV designated aty 245i fronrlfa mainatrack 25to either of apairo'f branch tracks designated 26 and 27, respectively.

-To this end, the rails'l are arranged at an ,angle with respect to the several tracks so as to allow ofthe necessary movement of the .carriage in properly positioning the track sections 22 and 23 with relation to the main and branch tracks. i

Inoperation, the carriage of the switch device may occupy any one of two extreme positions, the carriage being propelled to either position 4through the medium of the motor 20, it being understood that by energizing the motor 'the shafti19 will be actuatedk to effect a driving of the corresponding wheels. 16 in one direction or the'other, depending upon the direction of rotation of the mot-or 20. In lone eXtreme positiony of the switch device, the track' section 22 is disposed in connecting relation with respect to the main track 25 and the branch track 27so that the car 24: can move from the main track to the curved branch.v In lthe other relation with respect'to the main track 25 and the branch track 26. In eitherextreme position ofthe switch device, the wheels 16 abut the posts 18 so as toproperly define the two positions of the carrier.

Although I have shown a switch devicek particularly adapted for directing a monorail car from a main track'to either vof a( pair of branch tracks, it is to be understood' that the switch device maybe so constructed `extreme position of the switch device, the vtrack section 23 is disposed in connecting as to eiiect the direction of a car from a main track to a .multiplicity of branch tracks of either curved or linear form.

I claim as my invention:

l. A switch device comprising rails, posts at the ends of the rails, a carriage including wheels movable over the rails, said carriage being capable of occupying two extreme positions in either ofA whichthe wheels are` adapted to abut the posts, track sections on the carriage, and means for driving the carriage.

2. lA switch device comprising rails arranged in spaced relation toeach other, abutment members at the ends of the rails, a carriage including beams, wheels journaled on the beams and movable over said rails, tracks on the carriage, and propelling means for the carriage comprising a motor, a shaft connected. to certain of the wheels, and means operatively connecting said motor with said shaft. V3.1i switch device comprising` rails, posts at the ends of the rails constituting abutments, said 4rails including two end rails and an intermediate rail, a carriage including two end beams and a lnumber of intermediate beams securedin lspaced relation, wheels carried by the beams and movable over said rails, the wheels carried by the intermediate beams being between the spacedy latter, tracks sustained on the beams, and means for `propelling the carriage vcomprising agmotor, .a'shaft connected .to-certain of said wheels, and means for operatively connecting said motorw'ith said shaft.

4'. Aswlitch device rvcomprising spaced rails, said rails including two end rails and an intermediate rail, a carriage including two end beams anda number of intermediate beams secured in spaced relation, wheels carried by the beams and movable over said rails, the wheelscarried by the intermediate beams being between the latter, tracks sustained on the beams,vand means for-.propelling the carriagercomprising a motor, a shaftv connected to certain of said wheels, and means for operatively connecting said motor with said shaft. i

f5.,A switch device comprising :spaced rails,` said rails including twoend rails and an intermediate-Miha carriage including two end beams and a number of intermediate beams secured in spaced relation, wheels carried by the beams and movable over said rails, the wheels carried by the intermediate beams being between the latter, tracks sustainedon the beams, and means for propelling the carriage.

In testimonywhereofl yhave signed'my name to this specification. f
