RAILROAD-SWITCH.

SPECIFICATION forming part of Letters Patent No. 684,504, dated October 15, 1901. Application filed February 25, 1901. Serial No. 48,841. (No model.)

To all whom it may concern:

Be it known that I, EDDIE FROMM, a citizen of the United States, residing at Owasa, in the county of Hardin and State of Iowa, have invented a new and useful Railroad-Switch,

of which the following is a specification.

The invention relates to improvements in railroad-switches.

The object of the presentinvention is to im- IO prove the construction of railroad-switches and to provide simple, inexpensive, and efficient means for dispensing with the ordinary frog and to afford a continuous rail at that point and to enable the parts to be positively locked against accidental movement.

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

In the drawings, Figure 1 is a plan view of a railroad-switch constructed in accordance with this invention. Fig. 2 is a similar view showing a modification of the invention. Fig.

3 is a transverse sectional view on the line 3 3 of Fig. 1. Fig. 4 is a detail sectional view on the line 4 at of Fig. 3. Fig. 5 is a transverse sectional view 011 the line 5 5 of Fig. 1. Fig. 6 is a similar view on the line 6 6 of Fig. 2.

0 Fig. '7 is a sectional view on the line 7 7 of Fig. 2.

Like numerals of reference designate corresponding parts in all the figures of the drawlngs. I

5 1, 2, 3, and designate the rails composing the two tracks, and 5 designates a pivoted oscillatory rail which is adapted to connect the sections of the adjacent rails 2 and 3 to form practically a continuous rail and to dis- 4o pense with the frog usually employed at this point in switches. The rail 5, which is pro vided with a central pivot 6, has an enlarged base 7 and is connected at one end with a reciprocating slide 8, which is provided with a recess arranged between its ends and receiving the base of the pivoted rail 5. The enlarged base 7 of the rail 5 fits snugly in the recess 9 of the slide and is held against lateral play by the walls of the recess, whereby when the slide is looked, as hereinafter explained, the pivoted rail will be firmly held in its adjusted position. The slide 8 is preferably provided with a depending flange 10, arranged in a longitudinal way 11, consisting of a slot of an enlarged tie or sill 12 and adapted to limit the movement of the slide.

The reciprocating slide is locked at the ends of the way 11 by means of a pair of rock-shafts 13 and 14, having outer crank- arms 15 and 16 and provided with crank-loops 17 and 18.

The rock-shafts, which are journaled in suitable bearings at opposite sides of the slide, near the ends thereof, have their loops arranged alternately to engage the ends of the slide to lock the same against lo'ngitudi- 6 5 nal movement. NVhen the slide is abutting against one end wall of the slot which forms the way 11, the loop of the rock-shaft at the other end of the slot is arranged in a horizontal position upon the upper face of the sill or tie 12 and receives the adjacent end of the slide and holds the same against longitudinal movement. The other loop of the rock-shafts is arranged in a vertical position, and when the slide is reciprocated to carry it to the other 7 end of the slot the rock-shafts are rotated onequarter of a revolution and their positions are reversed to lower one of the loops to a horizon,- tal position and to raise the one which was in a horizontal position to a vertical position. The crank-arms of the rock-shafts are connected with a bar or rod 19, which is operated by mechanism hereinafter described, whereby the rock-shafts are simultaneously actuated, as above described. The connecting bar 'O185 rod is connected at its outer end by a link 20 with one arm of a bell-crank lever 21, which is fulcrumed at its angle and which has its other arm connected with an outer longitudinal connecting-rod 22, that extends to a go switch-stand 23. The other end of the pivoted rail is connected by a rod 24 with a bellcrank lever 25, fulcrumed at its angle and having one arm pivoted to the rod 24. and its other arm adjustably connected with the lon- 9 5 gitudinal rod 22, and when the latter is reciprocated by the operating mechanism the pivoted rail 5 will be oscillated and the slide reciprocated and the opposite locking devices operated.

The switch-stand, which may be of any desired construction, preferably consists of a too vertical shaft 26, provided at its ends with arms 27 and 28, connected, respectively, with shifting switch- rails 30 and 31 and the longitudinal rod 22. The shaft 26 is provided with a combined locking and operating device consisting of an arm composed of inner and outer sections 32 and 33, the outer section being pivoted and provided with a handle and adapted to be swung downward into engagement with notches of a head 36 of the frame of the switch-stand. The switch-stand is adapted to be operated in the usual manner to carry the shifting switch-rails into alinement with either track formed by the rails 1 to 4, inclusive, and this operation simultaneously sets the pivoted rail 5 and locks the same against lateral movement. The arm 28 is connected by a link 37 with a bar 38, extending across thetrack and connecting the shifting switch-rails.

In Fig. 2 of the accompanying drawings is illustrated a modification of the invention, and the pivoted rail 39 is connected at one end by a rod 40 with the switch-operating mechanism, and the other end of the pivoted rail 39 is arranged to be engaged ,by a pair of pi voted locking devices 41 and 42, which hold the pivoted rails firmly against stops 43 and 44. The locking devices consist of catches pivoted between their ends and provided with oppositely-disposed inclined upper edges l5, which are adapted to be engaged by operating-rods46 and 47, pivoted between their ends at 48 and 49 and connected by the means hereinafter described with the operating mechanism for shifting the pivoted rail 39.

The operating-bars are adapted to be oscillated to carry their engaging ends into and out of engagement with the inclined edges of the pivoted locking devices to depress alternately the inner engaging ends of the latter. The inner engaging ends of the locking devices are provided with recesses 50 to receive the bottom flange of the pivoted rail, and when the inner engaging end of one of the locking devices is depressed the outer end of the other lockin g device will also bedepressed to raise the inner engaging end of the same to a position for locking the pivoted rail.

The rods or bars have a limited movement independently of the pivoted rail to permit the; latter to remain stationary while the catches are being operated to release the said pivoted rail.

The operating-bars are connected by a rod 51, and the operating-rod 47 is connected at one end with a bell-crank lever 53, which is also connected with the rod 40. The bellcrank lever 53 is substantially T-shaped, and it has one of its arms connected by a longitudinal rod 54. with operating mechanism substantially similar to that heretofore described. The rod 40 is provided with a slotand-pin connection at its outer end at 55 to permit the operating-rods to be moved in advance of the pivoted rail, and the connections between the shifting switch-rails are designed to have a similar slot-andpin connection, so that the switch-rails will move simultaneously with the pivoted rail and not while the locking devices are being operated.

It will be seen that the switch is adapted to dispense with the frog usually employed in railroad-switches, and that it affords practically a continuous rail at that point, and that the pivoted rail is securely held in alinement with the rails of the track by the opposite locking devices. It will also be apparent that the locking devices are positively operated by the mechanism by which the pivoted rail and the shifting switch-rails are operated. a

WVhat I claim is p 1. In a railroadrswitch, the combination of a pivoted rail adapted to be oscillated to aline it with the adjacent rails, operating mechanism connected with one end of the pivoted rail for actuating the same, a pair of locking devices located at opposite sides of the other end of the pivoted rail and adapted to hold the same against movement, and means connected with the said operating mechanism for positively and alternately engaging and disengaging the said locking devices, substantially as and for the purpose described.
