IMPROVEMENT IN MECHANISMS FOR OPERATING RAILWAY-SWITCHES.

Specification forming part of Letters Patent No. 2] 9,095, dated September 2, 1879; application filed May 22, 187.).

To all whom it may concern: their carriers, being arranged in manner as Be it known that I, JOHN A. HEYL, of Bosrepresented. When onedepressor of a pair is ton,of the countyof Suffolk and State of Massadown upon its seat f the other will be raised chusetts, have invented a new and useful Imor off its seat. In other words, when the quadprovemeut in Mechanism for Operating the rantal or sectoral toggle is resting upon the Switch of a Railway; and dohereby declare slide-plate below it one depressor of each pair the same to be described in the following speciof depressors will be down upon its seat and fication, and represented in the accompanying the other will be oft its seat. drawings, of which Close to the toggles the plank or base G, upon Figure 1 is a top view, Fig. 2 a longitudinal which the slide A is supported, is furnished section, and Figs, 3 and 4 are transverse secwith hearings or standards 9 g, disposed with tions, of mechanism embodying my invention. respect to the shaft D in manner as shown, and The plane of section of Fig. 3 is through the serving to support it against lateral strain of quadrantal or sectoral toggle, while that of the toggles.

I be locked, so as not to be accidentallymoved The mechanism to be described is intended in manner to move the switch out of engageto be suitably arranged in arailway-track, and ment with the rails in alignment with which with respect to a switch thereof, to effect the it may be. movements of such switch from the main track The described mechanism for actuating a to the turnout, or the reverse, as may be reswitch is intended to be put in operation by the quired. conductor or engineer of a train or engine there The two switch-rails are to be pivoted to the of while such may be passing over one pair of two longer toggles, or to a slide extending unthe depressors. To do this he is to depress derneath and pivoted tothem, such slide befrom his engine or carriage a'wheel or some ing shown at A, and the said toggles at B B, in proper substitute, which, while moving along Figs. 1 and 2. At their inner ends these togupon one of the raised depressors of the pair,

There is to each gear movement of the switch, whereas, were I to a pair of such depressors, the two pairs, with havea bell-crank in the place of the quadrantal toggle the shaft would have to be revolved a half-revolution to effect such movement, and, as a consequence, a depressor to operate such crank would require to be depressed twice the distance it would when the quadrantal toggle is used. The advantage of the quadrant-a1 or sectoral toggle over a crank will thus be appardepressors, the shaft and its gears, and the quadrantal or sectoral and straight toggles, arranged and applied to each other substantially as set forth.
