SPCIIICATION forming part'of Letters Patent No. 714,240, datedXovember 25, 19h-(l2-` i Application filed September 2, 1902. Serial Fo. 12],7-81. @l0 MBU .To all whom it may concerne V Beit known that ive, SHELBY S. ROBERTS,
i `residing at Louisville, in the county of'Jel-'ferson and State of Kentucky, and ARTHUR II. MaXxresding at Evansville, in the county of Yanderburg and State of Indiana, citizens of the United States,have invented a new and nsel'nl Improvement in Switches for Street- Rnilways, of whiclrthe following isa specilication.
` Our invention relates to switches to be op-` erated by means of a rod; and the object of dur invention is to provide a switch which is firxnlyfixed when setand cannot be reversed or partly opened except in the inode provided,
while at the same time'cars may he backed past the switch in the direction opposite that of the switch, whiclra't onceresnmes its original position. lle atta-in these objects by the mechanism illustrated in` the accompanying drawings, in which -4 lfigurcl 1 is a plan of the contifivauce', with theexception of the cover, which isi-removed. Fig. -2 is a longitudinal section through the rails, tongue, and framework of the contrivance, showing an elevation of the rest of the mechanism; an elevation of the contrivance. Fig. 3 is a longitudinal section of the har and piston D E F GH in Figs. land 2, showingin elevation thejpi'ston,'pistoni-od, and spring.` Fig. 4 is a top View. of so much ofA the con` trivancefas is visible when the cover is on.
In all lign-resthe saine letters refer lo the same parts." Y
AA' are divergiug rails, being, as it here happens, on the left-handjsideot the track looking in ,thedirection of the arrow'in Fig. l.'
p i, .'B is thei'vedge-shaped movable rail,4 commonl'y called a tongue. Instreet-railw: ys

render it accessible from above.
. thest with-d rawn) passes somewhat more th:
half-way around the center-of the horizon! disk K'. Said piston is attached to said di approximately at the terzninus'of said goof 'neck by the pivot L.
The disk is at its ce ter connected with the framework S of t machine by the axleR; 'Projecting npwa from the surface of the disk near its out edge and attached rigidly to it is the pin l T is the cover, whichis placed over the co It can readily removed when necessar) for repairs. It h a slot U extending over somewhat more th: 'half the periphery of a circle, directly ov the possible positions of the pi'n M, so as The p exiends npwardinto said slot,and its mov ments are limited by the length of the sl;
` lV is a lug on the cover directly above tl axle R for the purpose olf Yfitting a rod so 1 to `move the pin M bya horizontal branch.
Onr contrivanee operates as follows: Thi the motorlnan' (or other person) desires change the switch, lle, with an appropria rod, shoves the piu aronndthe'arc Uof a ci 4 attached thereto is shoved to theleft--t-hat i outward.` The gooseneclk is then in the p sition indicated by dotted lines in Fig. The springwithinthecylinderofferssuiciel resistance to the piston to carry theclylind alongr with it, and the bar attachedto the la ter 'pushes the tongue over against the ra A. Of course to reverse the operation tl pin M'must be brought around from the `p sition M' to its original position. f There are two especial advantages to o1 contrivauc'e. l In the first place it is construc ed in such a manner that when the pin M in either of its lterminal positions .the ax L and the end of the gooseneckare broughti arrow) `this can be. done without inconvenienne,` without; ldisLurbing the switch, and.
youd theaxle R abishe center of the disk-fthe?, is, toa. position on the side of the axle R opposite to 'that of y the curve in elle "gooseneck The switch isiheielore locked, since no jar- "ring of nor pulling or pushing: of the tongue `can p-nslx or 4pull the gooseneck aronnd or fpast. ghe' central axle R, so as to alter the tongnes positiigm.` The onl y effect; can be to ".c'as'e atemporary giving or vibration by reason of the spring attachment. ItJ is there fore impossible for the posit-ion of the switch to change between the passge of the f rontand rear trncksof thecan In the second place, in
" case it becomes necessary to'back cars down the 'main track (inthe di'reeLion opposite the wilhonh danger of injury lo Lx-ack or rollingstock, although the switch be setfor acurve.
The 4flange of til-1e wheel'enters, of course, be-
`tween the tongue and therail at Lhefarther end. The springr within the cylinder givesnnder this extraordinary pressure snic'iently to allow its passage, and then anonce forces the tongue h a'ck to iLs'oi-ignal position.
The most ess'ennialieatnre of our contri\ ance is the spring-actnated locked psLon-rod.
The shifting anrllocking might be effected by a4 vertical movement converted into a.' horizontal motion of the piston by a system of'cog-wheels. \Ve prefer to operate the oontriwmce :isbove described.
Having'now described. our -contrivar whatwe claim as'onr invention, and de: to secure by Letters Pax1tis` i 1. In switchesfor sti'eetrailways, the el bination ofv a cylinder ierniinnting in' a l attached to, the tongue-rail, along witl spring-curated piston `vithin said cylinc' a piston-rod ending inve. gooseneek pifotec' a horizontal :revolnble disk, bearing a jecting pin, together with a correr havin; circo-lar slot, substantially as described.
2. In switches for street-railways, the c( binanon of a cylinder terminating in a. h attached. t-o the `t;o' i1f,ruerail, along witl: spring-actuated piston within said cylind a. piston-rod endingin a gooseneckpivoted t horizontal revolnble disk, bearing a proj@ ing pin, substantially :is described.
In switches for street-railways, theco hina/cion of a cylinder terminating in a b atpached to' the tongue-rail, along with spi-ingact'liated piston -within said cylind a psbon-rod ending in a gooseneck pivot to a. horizontal revolublel disk, together w means for revolving same, substantially described.
