Application filed May 15,'1916. Serial No. 97,733.

To all whom t may concern.'l

Be it known that I, MAGLOLRE METHoT,a subject of the King of Great Britain, and resident of the city of Ottawa, Province of Ontario, Dominion of Canada, have invented certain new and useful Improvements in Switches, of which the following'V in construction thereby occupying a mini-k mum of space, to obviate jarring on the car during the operation of actuating the switch, to simplify the construction, and generally to adapt the several parts to better perform the functions required of them.

With the above` and other objects in view the invention consists essentially of the improved construction particularly described and set forth in the following specification and accompanying drawings forming part of the same.

In the drawings:

Figure 1 is a fragmentary sectional elevation of a street car and railway embodying the present invention. I.

Fig. 2 is a transverse section through the casing located between the rails.

Fig. 3 is a fragmentary perspective view of the switch and co-acting links controlling the actuation of the same.

Fig. 4 is an end elevation of the wheels co-acting with the casing located between the rails. j

Fig. 5 is a transverse section of the casing ho'ising the mechanism located between the rai s.

Fig. 6 is a fragmentary perspective view of the bar carrying the wheels for depressing the plungers.Y

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents a street car of any usual type, and B a rail road provided with switching mechanism C adapted to be controlled from the motormans platform D in a manner to be made clear hereafter.

The switching mechanism C comprises a casing 10 provided with a corrugated top 11 having angularly disposed ends and dethe movement ofthe switch 12.

This mechanism comprises a pair of plungers 13 and 14 pivotally connected at their lower ends to the cranks 15 and 16 rigidly Vmounted on the longitudinally extending and horizontally disposed spindle 17 which extends to a point adjacent tothe switch12, at which end it is provided with a crank member 18, having a slot 19in the arm thereof inwhich the bolt 2Oa is slidably mounted, this bolt being pivotally connected to one end of the link 20, the other end of the link being connected by `a pin 2l to the lower end of theoflset link 22, the other end of which is pivotally connected 'to the switch l2. y

. signed to house the mechanism controlling The plungers 13 and 14 are lprovided with enlarged removable heads 23 and 24 which slidably engage with the orifices 25 and 26 extending through the top of the casing 10, the lower face of the said heads being adapted to engagevwith the upper ends of the springs 27 and 28, the lower ends of which engage with the transversely extendlng members 29 and 30 secured to the sidesof the casing.

j It will be understood that the cranks 15 and A16 are located diametrically opposite each other so that the spindle 17 is capable of being rotated in both directions effecting the opening and kclosing of the switch 12.

' The spindle 17' is housed in a suitable conduit 31y the rear end of whichl is connected to the part o f the casing l() which houses the plungers 13 and 14, while the forward end is connected to the casing 31a which extends transversely between the rails and houses the crank member 18 and links co-acting therewith.

Inspection of the i' plungers in the casing y 10 is conveniently obtained through the door 32hingedly secured' to the top of the said casing and heldin elevated or closed position by the fastener 32El pivotally mounted on the door adjacent to the edge thereof, while to facilitate drawing olf surface water liable to collect in the said casing, a drain pipe 33 is provided.

The car apparatus which co-acts with the above described track apparatus consists of a pair of wheels 34 and 35 rotatably mounted on the bifurcated end of the bell crank 36, the arms of which are offset thereby enabling the said wheels to engage with the heads 23 and 24 of the plungers 13 and 14 respectively.

This bell crank is rigidly mounted on the shaft 37 rotatably supported by the bracket 38 from the longitudinally extending bar 39, the reduced ends 39a of which are slidably embraced by the lower bifurcated ends of the brackets 40 secured to the fioor of the car A, the downward motion of said bar being limited by the pins 40a passing through the said brackets. The upper face of the bar coacts with the springs 41 adapted to obviate any jarring when either of the wheels 34 or 35 coacts with the plunger' heads.

It will be readily seen that by reducing the ends of the bar 39, when either of the wheels 34 or 35 engages with the head 23 or 24 of the plungers 13 or 14, any tendency to longitudinal movement of the said bar is eliminated since it will engage with the edges of the brackets 40.

rlhe shaft 37 is provided with a crank arm 42 which is pivotally connected to one end of the link 43,'the other end of which is pivotally connected to one arm` of the bell crank 44 rotatably supported by the bracket 45 from the bottom of the car A., the other arm 46 of the bell crank being connected to the lower end of the link 47, the upper end of which is connected to the disk 48 carried by the spindle 49 rotatably supported in the quadrant frame 50 secured to the car A adjacent to the control levers so that actuation of the said diskmay be readily accomplished by the driver.

To facilitate in rotating the spindle 49 and disk 48 to the desired extent, a lever 51 is provided carrying a' suitable detent 52 adapted to engage with serrations or teeth 53 provided on the periphery of the casing 50.

The assembly of the switch control will be readily understood from the foregoing description.

When a car fitted with a mechanism of the above description is in use, and when the said car is approaching a switch, the driver actuates the lever 51, which through the medium of the link 47, bell crank 44, link 43, and bell crank 36 and engages the wheel 34 with the plunger head 23, thereby transmitting motion to the spindle 17 and setting the switch 12 so that thev car can travel on its desired course without stopping to effect the positioning of the switch.

Should the driver desire to take the other road, say the side linethe motorman or driver would actuate the lever 51 so that the bell crank 36 would be rotated and permit of the wheel 35 engaging with the plunger head 24, thereby rotating the spindle 17 in the opposite 'direction to that above described `and so open the switch .12 and permit of the car entering the side line.

From the above description it will be seen that l have invented a car switch which can be advantageously utilized onstreet railways, and will permit of `switches being operated by the approaching car without the necessity of the said car being brought to a stop.

As many changes could be made in the above construction, and many apparently widely different embodiments of my invention within the scope of the claim, constructed without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying,specification and drawings, be interpreted as illustrative, and not in a limiting sense.

What- I claim as my invention is:

A device of the class described comprising a casing having a corrugated top provided with angularly disposed ends, plungers slidably mounted in the casing, a longitudinally extending shaft, cranks extending from diametrically opposite sides of the shaft and operatively connected to the lower end of the plungers, a crank on the end of the shaft havinga slotted arm, an o'set link operatively connected to a rail switch, a link pivotally attached to the offset link and adjustably attached to the said slotted arm, and means for depressing the said plunger. Y

1n witness whereof l have hereunto set my hand in the presence of a witness.

MAGLOIRE METHOT.
