.Specification ol Letters Patent.

Patented June 22, 1909.

Application led March l2, 1909. Serial No. 482,922.

To all w/zoml 'it may concern:

Be it known that l, Darin lslxoonn lint.- LETT, a citizen ol' the United at Bowling Green, in the county ol Warren and State of Kentucky, have invented certain new and uset'ul .lmproveimxnts in Derailing-Switches; and l do hereby deelarc the following to be a l'ull, clear, and exact description oi' the invention, such as will en'- able others yskilled in the art to which it api pertains to make and use the same.

My invention relates to improvements in derailing switches, and has l'or its object to provide a construction for the purpose men'- tioned, which shall possess, at once, safety, and simplicity ot' operation.

One 0l' the objects ot my improvement is to so construct the device that the elements of the weather, snow, ine, etc., will have no damaging effect upon the parts.

Another object ol' this improvement is tht` provision oll a device ol' the character described, which presents no opening in the rail, or loose rail, sueh as characterizes the By this means', absolute safety is insured t'or a passing train, at all times.

Still another object, is to so Construct the parts that the derailing member is rendered Capablev ol' quick and easy movement.

Still a further object is the provision ot' a derailing member, in combination with a signal stand, l'or indicating the position ot the switch lor danger or safety.

Vith these several objects and advantages in View, my invention, in its prel'erred embodiment, includes the torni ol' construction hereinafter described in detail, and pointed out in the appended claims,

In the accompanying drawings', in which like reference characters ret'er to rorrespomling parts in the several views, and which is to be read in conjunction with the t'ollowing speei'lieatioi'i, t'mming a part thereot, Figure il is a plan view 0ll a switch, provided with my improved devices, and showing the deraiiing v member in nornial or safety position; Fig.

Il is a similar View, showing the detailing member in danger position; and Fig. lll is a vertical section through the dei-ailing mem- Referring more particularly to the drawing, A A designate the rails oi' the main traf-k, and B B the rails ol' the siding.

C C are the pivoted switch-tongues, which t are connected States, residing C* pivoted at C,

to the slidingl cross-bar C. Pivoted to the eross-bar C is an angle-lever in turn, pivolnlly connected to the angle-lever() is a rod C", connected to a second angle-lever C7. lhe crossbar Us is pivotally secured to one arm ol the angte lever C7.

C is a switch stand l'or controlling the sition otA the switch-tongues C C.

'l'he derailing member is designated as B?, and consists of a comparatively heavy, solid metallic body having the eonlignration otl hall ot' a pear, when divided by a rentral longitudinal cut. ,lt is provided with a llange B3, adapted to overlh` the rail B, and with lugs lr arranged to assume a position in contact with and adjacent the side of the rail B when in derailing position. The derailing member ii* connerted to the cross-bar C, and adapted to move therewith, having a sliding movement upon thel plate B5. Connected to the derailing member B2 is a rod B which is arranged to operate a signal B7 in the signal stand B, so as to indicate the position olI the switch, tor danger or safety.

.in the operation, in the position ot' the parts as shown in Fig. I, the switch is open to permit a train to pass on the siding, and the derailing member is removed from the rail so as to permit free movement of the train. Upon closing the switch, the cross bar C is operated through the angle levers .ft

o and C7 and netmeeting rods and is moved over carrying the dei-ailing member into such a. position that its flange Bihaving a Curved upper surl'ace,is nornmlly positioned over the rail B, and the lugsB" are in contact with and immediately adjacent the side ot'the rail. Thus. ill a train already on the siding, by accident, becomes displaced and starts toward the 'main track, it will immediately be thrown t'rom the siding by means of the member B". Simultaneously with the movement olA the parts just described, the signal B7 is operated to indicate the respective position ot' the derailing member.

What l desire to secure by lietters-Patent and rlaim is:

t. ln a dorailing switch, the combination with a stationary rail, of a derailing member comprising asemi-pear-shaped metallic body, a llange thereon arranged to overlie the rail, lugs ada )ted to contact with the side of the rail, and means for moving the derailing member toward and away from said rail.
