' @uitrit tats# 'atrnt @frn JAMES T. CLARK AND JOHN D. BESLER, OF GALESBURG, ILLINOIS.

Letters Patent No. 80,601, datedvrlugust'fl, 1868.

TO'ALL WIIOM IT MAY CONCERN:

Be it known that we, JAMES T. CLARK and JOHN D. BESLER, both of Galesburg, in the county of Knox,l and State of Illinois, have invented a new and usefulFTrcble-Sat'ety Itailroad-Switch and we deherehy declare that the following is a full and exact description thereof, reference being had tothe accompanying drawings, making part of our specification, in which- Figure 1 represents the position ofthe rails and switches adjusted for the main track.

Figure 2, the same, adjusted for the right track, and

Figure 3 the same, adjusted for the left track. i

The nature of our invention consists in thecombination of two short and'two long pointed movable rails with two stationary rails, so arranged that it forms a treble-safety railroad-switch, as will be hereina-Fterffully explained.

To enable others skilled in the art to make and use our invention, we wlll proceed to describe its construc,

` tion and operation. Y

A is a point, to which come three different railroad-tracks, B B', C C', and D D', C C being the main track. The ends of the outside rails, I3 and D', of these tracks connect with the ends of the two stationary rails E E', extending from the point A to the point I", Where they meet the rails TKT of the regular track.' Inside ofthe stationary rails E E', at the point A, are attached to the tie, in a usual way, four movable pointed rails, consisting of two pairs, et' ditcrent lengthsthe rails Gr Gr' of the shortest pair being placed opposite the rails O and I3', and the rails II H', of the longest pair, opposite the rails D and C', each pair being moved. independently by connecting-rods m n and target-levers M N, which are supposed to be worked by one man. We make the short movable pointed rails about fourteen, and the long onesrabout twenty-four feet long, but this length may vary more or less, according to circumstances. A v

The operation consists in this, that for the main track C @'the switches are moved in opposite directions, the short switch G G being switched to the stationary rail E, and the long switch II II' to the stationary rail E', as represented ou iig. I. i ,For other tracks, both switches are moved'in the same direction, viz, for the track B B they arc moved to the-rail E', as on fig. 2, and for the track D D' they are moved to the rail E, as on iig. 3.

'i The advantages of our treble-switch over the common treble stub-rail switch now in use, are obvious. There,

if a movable bar is not in its proper place, the train, by leaving the depot, where most of theiaccidents: happen, i will run oit` the track, while in our arrangement, ii' a switch is not properly placed, the ilanges of the car-wheels, entering gradually and wedge-like into the spaces 'between the stationary and the pointed rails, wili set the switches to their proper places, and although they will bend the connecting-rods and the target-levers of the switches', will never run ofid the track.

We are aware that a switch has heretofore been made having one pair et' movable rails, and therefore wc do notV claim such; but, having described our invention,

What we claim as our invention, and desire to secure by Letters Patent, isv The combination ofthe two short, G G', and two long, II II', pointed movable rails with two stationary rails E E', forming a treble-safetyv switch, the whole arranged andoperating substantially as and in the manner herein described and specified.

J. T. CLARK, l J. D. BESLER.
