B0 it kllOWD that I, GEORGE WJ SPAULDING, 0f' Norton, in the county of Bristol, and State of Mnssnchusetts, have invented n new and/improvedl Safety Switch, of which the followin'g'is a. full, clear, end emot description, reference being hncltothe accompanying drawings, making port of this specification, in which Figure 1 represents n* portion of'a railroad track and switchv containing my improveinent; and
Figure 2 is a. view of the same, with the switch turned o from the main trock.v
The object of my invention is to prevent an engine or train of cors from running'oii` the track by' the insplacement of the switch; and the invention consists in forming e. vgroove in the inztinroil or portion of the switch in such o' manner es that, when the switch is misplaced, the iiztnges of the wheelsvon one side of the car or engine will enter the said groove, nmlbe properly guided thereby to tlielinoin rail of the switch, the se'veof ports of the switch being made oi' the ordinary rails used upon the road, and secured together by means o` bolts, or otherwisefso that the switch corr be inode' of magterial on tire rood at any time or piece where convenient. A Referring tothe drawings, a a represent V'tho-mainfrail o'i' the track, and a b d the portion composing the switch, supported in the usual manner et its free end ontlle cross-piece g. Fig. l represents the switch proper 'position for the cors passing in the direction of the arrow on the mein track. Near the free end of 'the switch one'ither side is n groove, c, in the' main vmil a, so arranged in relation tp the onterber I) of the switili tiret 'when the latter is turned froin tlieinain tr'nek to aside track the flange of the wheel upon one side will enter ,the groove c, n nd thus be guided directly upon the main track et, thereby effeetnelly preventing the ears from leaving the track, the opposite wheel passing npon the section i on the otherside. he portions of the 'switch may all be made of ordinary rnilsqes used inlmztking the track, and een' be framed and put together et any of 'the workshopson the lino of the' railroad possessing the proper facilities, instead of being enst in. one piece.
The parts muy readily be secured together in any suitable manner, and should any portion become injuredor defective it may be easily-removed und repaired or replaced by anotliorpieee. f is o. guard rail, placed on the inner side of the switch, and serves :issn additional means for directing the flange of the wheel upon 'the mvaintrack, v
What I claim as my invention, nnd'oeSIre to secure by Letters Patent, is- A safety switch for railroads, comnosed of thegrooved rail a and the parts b and d, when-constructed and operating substantially as above set forth. v
l In testimony whereof I have signed my mime to this specification in the presence of two subscribing witnesses.
