SWITCHING DEVICE.

Application filed June 26, 1909. Serial No. $4,535;

a manually operated mechanism by meansof which a switch can be thrown.

Another object is to provide a switch.

throwing device that can be operated from the car.

iVith these and other objects in view, the present in\-'e1'1tion consists in the combination and arrangement of partsas will be hereinafter more fully described and particularly pointed out in the appended claim, it being understood that changes in the specific structure. shown and described may be made within the scope of the claim, without departing from the spirit of the invention.

In the drawings forming a part of this. specification and in which like numerals of reference indicate similar parts in the sev-- eral views, Figure 1 shows a top view of a track section, provided with my throwing mechanism, the switch being shown as closed, Fig. 2 shows a top View disclosingthe switch as open, Fig. 8 shows an enlarged i shows a front view of a fragmentary pordetached detail of the cam head, Fig. at

My invention is particularly adapted to be used in connection with trolley and other street cars, and in Fig. 1 the numeral 15 designates the rail, supported upon the ties 16.

The rails leading from the switch are marked 14, while the two switch points are marked 17 and 17. The ends of these switch points 17 and 17 are secured to the bridle bar 18, carrying the pivot pin 19 to which is secured the ends of the sway bar 20, this bar being held to the pivot 21 fixed Specification of Letters Patent.

The edges of the striker heads are rounded and these two striker heads 11 are obliquely held with their forward edges converging toward one another as clearly shown. Each throw rod 32 is provided near the upper end with a circumscribing stop collar 33 while each throw rod 30 is provided near its upper 'vided with is provided with two such throw.

with a stop collar 27. Held about these ,maJor rod portions 32 are the helical springs 36' which at their upper ends work against the stop collars 33,'so that these throw rods areheld in yielding spaced relation to one another. These rod sections 32 are of such a length, that the ends lie flush with the floor of the car, the openings 35 and 35 within the bottom of the car being somewhat larger than. the diameter of. the rod stems 32. ;T he striker headll determines the upward position of these throw rods as these striker heads contact with the lower under face'of the :bracket portion 45. Extending from the central portion brace'rod 9 having the securing ears'8 and 8 provided with suitable bolts so that these brace rods may-be secured to the under sur- .face of thel'platfotmf The car at each end I rods. In connection with these throw rods, I use a push cap comprising the tubular sleeve 39 ending above in the head 50 which is pro the corrugated surface to be firmly engaged with the foot of the operator.

The operation of my device is very sin ple. lithe sway gated bar is in the position indi in Fig. 1, and the perator decides to take and forcethe rod p g the siding l4, helwould place the sleeve of the push cap upon the throw rod to the right down onthe tension 36. The

A through t sway bar str' er head is at all times in the path of these throw rods. 'As these striker heads are obli uely positioned, as they (pass e slot within the cam head, the is act-uated to carry the switch points to their opposite positions and thus open the main track to the siding.

of the bracket is the downward movement desired to send the car following down the main line, the operator would depress the throw rod so as to throw the sway bar into its original position. The throw rods can only be operated by means of the push cap which as has been said is inserted within the socket surrounding the throw rods. By this-means there is no likelihood of the throw rods being accidentally depressed at any time, to improperly throw My switch throwing mechanism in no way interferes with the operating or driving.

mechanism of the car proper, and this can also be said of the switch throwing mechanism which permits the switch being thrown in addition by an ordinary switch stand mechanism.

The operating mechanisms as embodied in my invention are simple of construction, are

readily accessible so that repairs can be easily made, and are positive in their operation. The throw'rods as shown are held in yielding spaced relation, and the push capv can be readily replaced from one rod to the other. The constructiom further in no way detracts from the sightly appearanceof the vehicle.

What isclaimed is:

In combination with a pivotally held sway bar, and cam heads'secured to said bar, ,of two J-sha-p'ed throw rods secured to a car, a bracket depending from the car for guiding said throw rods and for holding the same in a vertical position, collars forming a part of the major stem portions of the throw rods, stop collars forming the ends of the short members of said throw rods, and heli' cal springs encircling the major portions of the throw rods and disposed between the collars forming a part of the same and the lower portion of the said throw rods in an elevated position,- the said stop collarsforming the ends of the bracketfor holding the short members of the throw rods thereby HOLLAND F.
