' RAILWAY SPECIFICATION forming part of Letters Application filed January 3, 1885.

To aZZ whom it may concern:

Be it known that I, HUnEnr I. Tanssre, of St. Louis, Missouri, have made a new and useful Improvement in Railway-Switches, of which the following is a full, clear, and exact description.

Th e improvement relates to switch es adapted for crossings.

It consists in the means especially described and claimed for operating the switch-rails.

The annexed drawings,' making part of this specification, illustrate the improvement.

Figure 1 is a plan of a switch of the kind under consideration and in which the improvement in question is embodied. The switch is closed and the crossing is open. Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Fig. 3 is a bottom view of the parts immediately connected with the switch-rails. Fig. 4 is a view in perspective of the rockshaft used in operating the switch-rail mechanism. Fig. 5 is aside elevation of the switchstand, and Fig. 6 is a section on the line 6 6 of Fig. 5. The last five views are upon an enlarged scale.

The same same parts.

A A and B B represent the lines of rail which constitute the two tracks which cross each other.

C 0 represent the frogs at the center of the crossing, and O 0 represent thefrogs at the ends, respectively, of the crossing.

D represents the fixed curved rail used at one side of the crossing in switching, and D represents the fixed curved rail used at the opposite side of the crossing in switching, and D D represent the two fixed rails used at the middle of the crossing in switching.

E E E E represent the two pairs of switchrails which are operated together at one side of the crossing, and F F F F represent the two pairs of switch-rails which are operated together at the opposite side of the crossing. The four pairs of switch-rails are adapted to be moved simultaneously, and so as to open or close theswitch, as desired, and in the ordinary manner.

The means for operating the switch-rails is, as stated, that part of the construction to which the improvement has reference.

letters of reference denote the -SWITCH.

Patent No. 333,901 dated January 5,1886.

Serial No. 151,914. (No model.)

G G G2 G represent the four switch-bars, which connect, in the usual manner and respectively, with the four pairs, E E, E E, F F, and F FZof switch-rails. The switch-bars at their outer ends connect with a rock-shaft, H, Figs. 1, 2, 3, 4, 5. This shaft, adapted to be rotated reciprocatingly in suitable bearings at the side of the crossing, but not shown in the drawings, is provided with the arms h h 71/ If, to which the switch-bars are respectively jointed, as shown in Figs. 1, 2, 3, and midway in its length is provided with or is constructed to form the crank h. The rockshaft may be made in one piece and have the crank 72. attached to it; or it may, and as shown, he made in two parts, h 71", which are upturned at h to form the crank, and which, by a universal joint, are connected with the bar J, which in turn leads to and is connected with the upright crankshaft is of the switchstand K. The parts h h are provided with a bolt, h, which passes through a block, h and the switch-stand bar J is forked at j j to receive the block 72. and is jointed thereto by means of the bolt h", which passes vertically through the parts j j h". The crank-shaft 7c is journaled at k, is adapted to be rotated by means of the customary lever, I0 and is provided with the pinion This pinion is intergeared with the gear L upon the targetshaft Z, which supports the target Z, and is suitably journaled in an upright position in the switch-stand. The pinion k is proportioned to the gear L as one to two. This is to enable the crank-shaft 7c in operating the switchqails to make a half-revolution, and thus bring the crank k of the shaft 70 to a deadcenter in each position of the switch-rails, and at the same time turn the target Z but a quarterrevolution around.

I am aware that four pairs of connected switch-rails have been operated simultaneously by means of a sliding bar, which at its ends is jointed to double-elbow levers, which in turn are connected, respectively, with the two pairs of switch-rods respectively at the ends of the crossing, the sliding bar in its op eration being moved endwise. Such a construction, even 1f new with me, would not answer my purpose, many joints intervening for not only are there between the switchstand and the switch-rails, and consequently much lost motion, but also there is this serious objection: The sliding bar is continually lengthening and shortening by reason of heat and cold. This in turn affects the position of the switch-points. If the sliding bar is too long, one portion of the switch-points is not exactly placed, and if too short the other portion is misplaced.

It is essential that the switch-points be exactly moved and placed to prevent accident, and this I accomplish by employing a rockshaft in the place of the sliding bar and cranks in the place of double elbows.

I claim- 1. The combination of the switch-rails, the switch-bars, the rock-shaft H, having the arms 71. h h k and crank h, the bar J, the crankshaft is, and the switch-stand K, substantially as described.

2. The combination, with the rails of the crossing lines and the fixed switch-rails, of the tapering movable switch-rails at the ends of said fixed rails and adapted to be pressed against the main rails, the switch-bars carrying said movable tapering rails, the rock-shaft and arms linked to the switch-bars, as described, the crank h and pitman J, and the crank 70, having the pitman pivoted thereto at such point as to be on the dead-center when the tapering rails are pressed against the main rails, and means for operating the crank k, substantially as set forth.

3. The combination, with the rails of the crossing lines, the fixed switch-rails at the end of the latter, and the bars and links for operating the same, of the horizontal rock-shaft having the crank it, the pitman J, pivoted horizontally and vertically to said crank, and the shaft is and horizontal crank is, to which the pitman J is vertically pivoted, substantially as set forth.
