To @ZZ whom it may @encerrar A Be it known that-I, GEORGE W. SnANE, a

lumbus, in the countyof Franklin-and State useful Impro ement' in Frogless Switches, of

Y lowing isa specication. lll/Iyinvention relates tothe improvement of frogless' switches; and the` objects pf my invention are to provide a railway-track with .the-,main track may be temporarilymad'continuous at the usualepoint of its junction with the switch-rail and whereby sa-id main track may be broken and'theswitch-rail made continuous therethrough, to providea shifting rail-sectionwithimproved means for operating and supporting the same, to obviate the'employmcn tjef a-frog and guard railsuand. to produce other improvements the details of construction of which Will be more fully These objects I accomplish in themanner illustrated in the'accompanying drawings, in which-l Figure 1 is a plan view of a portion of a main track and switch-track having my improvement and showing the main vtrack broken. Fig. 2is a plan viewof the shift-ing 0r swinging rail supporting plate.` Fig. 3 is a side elevation of the same. t tional view on line of Fig. '1g-and Fig. 5 is a sectional'view on line y y of Fig. 1.

Similar numerals refer to similar parts throughout the several views.

l and 2 represent, respectively, the inner and outer parallel rails of a main track, and 3 and 4 the inner and outer rails of a switchtrack,and 5 represents the usual switch-puin ts, which are adapted to be connected in the ordinary manner with the switch-rails 3 and 4. In carrying out my invention sections of desirable lengths of the main-track rail 2 and switch-rail 3 are removed, and at the center of the space thus formed between the separated rail portions 2 I secure upon one of the ties 6 a plate 7, said plate being provided with a transverse channel 8 on its upper side, which at its central. point is equal in Width to the width of the base of a track--rail, and from which said central point said channel is formed daring toward opposite sides of the plate. WVithin thc channel 8 is seated the Fig-"1t is a secserial no; 9,660. (No man.)

base of a swinging track-rail section 9, the latter being adapted when properly'turned `to ll the space between the ends of the trackrails.2 or ends of the track-rails 3. On opposite sides of the central portion of the railseetion 9 I employ clamping-plates 10, the latter having rounded lateral projections in which-,are formed vertically-grooved slots 11. Through these slotted openings extend up"- wardly the upper portions of Vertical pinsor .bolts 12,v which rise from the'under sides of vthe plate' 7.

Between the converging end portions of the rails 2 and 3 Iprovide fillingblocks 13, these con verging rail ends, together wththe ends of the rail-section 9, being adapted to'bearv upon tie-plates 14, which ad-v jacent to the ends of the filling-blocks 13 are formed with shallow upwardly projecting stopribs or` shoulders 15,V against which the bases of the rail-sections 3 andl2'are adapted' ing plate 14.

2O and 21 represent parallel operating rods or` bars which extend in the direction of the length of the ties and which pass beneath the outer track-rail 4. The inner portion of the operating-bar 2O is pivotally connected at 2` with one end of the bar 19. This operatingbar 20 extends beneath the rail-section 9 and has formed therewith a hook or shoulder termination 22, which engages-the outer side of said rail-section 9. The inner side of said rail-section is similarly engaged by a block 423which is detachably secured tothe bar 20. The operating-bar 2l is in a like manner provided with a rigid rail-engaging shoulder '24, corresponding with the shoulder 22, and with a detachable engaging block 25, corresponding with the block 23, whilethe end of said bar 2l beyond the shoulder 24. is pivotally connected at 2l with one end 'of the remaining bar 19.

On the outer side of the outer switch-rail i I fulcrum upon convenientties bell-crank levers 26 and 27, one arm of thc-lever 26 be- IOO ing pivotally connected with the outer end of the bar 2l and the corresponding arm of the lever 27 being similarly connected with the outer end of the arm 20. The remaining arms of these bellcranks are respectively connected with laterally-projecting lugs 2S and 29 o'f an operating-rod 30, which is xnovably supported in suitable keepers 31, mounted. upon the tie ends. cru 1n on one of t-he tie extensions opposite the switch-points a bell-crank, one arm of which has a pivotal connection with the outwardlyextending portion of a bar 33, which extends under the switch-rail 4 and is connected with the switch-points 5. The remaining arm of the bell-crank 32 is pivotally connected with the rod 30.

In Fig. l of the drawings I have shown the swinging rail-section 9 thrown into alinenient with the track-rail sections 3, thereby completing the switch-track across the inner maiu-` track rail. In order to break the switch-rail and close the space between the sections of the main-track rail 2, the rod 30 through the medium of a suitable lever or other operating device is forced inthe direction of the arrow, with the result thatthe rail-section 9 is swung until it is in alinement with the rail-sections 2. It is obvious that a reverse movement of the rod 30 must result in again closing the space between the switch-rail sections 3.

While I have sho wn herein a swinging-rail section, it will be observed that said rail section is not provided with a central pivot, as is common iu constructions of this character, and that the inclined vertical shoulders of the plate 7, which result from the flaring form of the channel in said plate, will operate to limit the swinging movement of the rail-'section 9 in either direction. It will also be observed that the swinging rail will be further assured in its position and its movement further limited positivelyby the pins or bolts which work in the slotted openings 11.

In order to provide against a longitudinal movement ol thc rail-scctons, I have formed As indicated at 32, I fuif* the shallow upwardly-projecting rib l5 on each of the plates 14,`th is rib not being of sufficient height to interfere with the flanges of car-Wheels which pass over the rails or of sufficient width to break the desirable continuity of the rail-sections. Owing to the fact that I have provided a detachable connection of the blocks and 23 with the bars 2l and 20, it will be observed that these blocks may be readily removed, together with the .plates 10, to admit of the removal of the railthe rail-sections, said plate having a trans verse channel formed flaring from opposite sides of its center, of a rail-section 0 bearing centrally in said 'plate channel, clamping-` plates on opposite sides of said rail-section having slotted openings therein, guide-pins projecting from said plate 7 through said slotted openings, outwardly-extending,operating-bars engaging said rail-section 9, leverbars 19 joiutedly connecting said operatingbars with rigid ties, jointedly-connected arms between the bars 19 and rail-section 9 and means for imparting a simultaneous outward movement to one of said operating-bars and an inward movementto the other, substantially as specified.
