RAILWAY- SWITCH.

SPECIFICATION forming part of Letters Patent No. 442,096, dated December 9,1890.

Application led May 22, 1890.

To all whom, t may concern:

Be it known that we, ROBERT J. BOOTH and J osIAH BAUGHMAN, citizens of the United States, residing at Garner, in the county of White and State of Arkansas, have invented a new and useful Railway-Switch, of which the following is a specification.

The invention relates to improvements in railway-switches.

The object of the present invention is to simplify and improve the construction of railway-switches and enable the ordinary oonstruction of frog to be dispensed with and to insure a continuous line both for the main line and the `side track.

The invention consists in the construction and novel combination and arrangement of parts, hereinafter described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

i In the drawings, Figure 1 is a perspective View of a frog constructed in accordance with this invention, the switch being open to the main line and the main line being shown continuous. Fig. 2 is a plan view showing the frog closed to the main line. Fig. 3 is atrausverse sectional view on line of Fig. 2. Fig. 4 is a detail View ot the frograil.

Referring to the accompanying drawings, 1 l designate the rails of a main line, and 2 2 designate the rails of a side track, which rails are mounted upon ties 3 in the usual man ner. The main rails l are arranged in the same horizontal plane, while the side rail 2, that crosses the main rail, is elevated sutilciently to bring the top flange of it above the tread of the main rail and enable the frograil 4 when closed to rest upon the main rail and form a continuation ot the adjacent side rail 2. The frog-rail 4 has its web and bottoni flange cutaway at 5, and the end G of the frograil is beveled and matches the beveled end 7 of the side rail 2 and forms a continuous side rail and dispenses with the ordinary eonstruc tion of Jfrog usually employed at this point. The elevation of the frog-rail 4 and the adjacent side rail is only about two inches above the main rail at the highest point, or about the thickness of the top flange of a rail, and

passage of trains. The frog-rail is connected by a bar 8 with an idle-rail 9 and an L- shaped arm 10 ot' a vertical rock-shaft 11, that is mounted in a stand 12, and the stand is secured upon the end of a tie 13, that extends under the idle-rail and the main and side tracks, and has secured to its upper face chairs 14 and 15, the latter of which forms a bearing upon which the frog-rail 4 slides, and the former has secured to it the beveled end 7 of the side rail 2 and the beveled end 1G of a guard-rail 17, which protects the pointed end of the side rail 2. The connecting-bar 8, that extends from the frog-rail to the L- shaped arm 10 of the rock-bar 11, is connected with the frog-rail and idle-rail at points intermediate of their ends, and their free ends are connected by a bar 18. The arm 19 of the rock-shaft 11 is connected witha similar rock-shaft 20 of the main switch-stan d 21, that operates the switches by a rod 22, and the shaft 20, which is mounted in the stand 21, is provided with an L-shaped arm having one end connected with a rod 22 and the other end pivoted to a bar 23, which is connected with hinged sections 24 and 25 ot the main rail l and the siding-rail 2, and when the rockshaft 20 is turned the hinged section 24 of the main rail is carried away from the side rail, and the hinged section of the side rail, which is beveled at 2G, is brought into contact with and forms a continuation of the main rail, or vice versa, and simultaneous with the operation of the hinged sections the frog-rail is opened or closed, accordingly as the the side track of the main line is continuous. The hinged sections 24 and 25 are further connected and braced by a bar 27, that hasits end pivoted to the hinged section about niidway the length of the saine, and the switch is normally held open and the main line maintained continuous by springs 2S.

It will readily be seen that the switch is simple and inexpensive in construction and easily operated and dispenses with the frog usually employed.

l. The combination, in a switch, of the main rails, the siding-rails 2, the one crossing the main rail being provided with the beveled end the rise is gradual and hardly perceptible and does not interfere in the least with the 7, the guard-rail having the beveled end 1G,

arranged contiguous to the end 7, and the frog-rail having its web and lower flange kcut away at 5 and provided with a beveled end 6, adapted vto forni a continuation of the adjacent siding-rail, substantially as described.

2. The combination, in aswitch, ofthe main rails, the siding-rails, the one crossing the main rail being provided with the beveled end 7, the guard-rail having a beveled end arranged Contiguous to the end 7, the frog-rail having its web and bottom flange cut away at 5 and provided With a beveled end 6, adapted to lap the main rail and form a continuation of the siding-rail, and the idle-rail connected to and invin'g with the frog-rail, substantially as described.

3. The combinatiomin a switch, of the main rails having the hinged section 2l, the sidllritiiesses:
