FRANK K. DEKAN AND AUGUST GLAUBEB, OF LORAIN, OI-IIO.

AUTOMATIC GATE FOR RAILWAY-CROSSINGS.

Specification of Letters Patent.

Patented Nov. 11, 1913.

Application led March 11, 1913. Serial No. 753,603.

To all whom, t may concern:

Be it known that we, FRANK K. DEKAN, a subject ot the Emperor of Austria-Hungary, and AUGUST GLAUBER, a citizen of the United States, residing at Lorain, in the county or" Lorain and State ot Ohio, have invented certain new and useful mprovements in Automatic Gates for Railway- Grossings, of which the following is a specification.

This invention relates to automatic gates tor railway crossings, and has tor its object to provide improvedV operating mechanism tor gates ot the vertically tilting arm or mast type, so that on the approach oi' a train the gates will, drop, and after the passage of the train the gates will litt.

The invention is illustrated in the accompanying drawings in which- Figure 1 is a plan view ot a crossing and the gates beside `the same. Fig. 2 is a perspective view showing a pair of gate boxes or `supports at one side of the crossing. Fig. 3 is a front elevation of one of the boxes, showing a signal bell. Fig. t is a side elevation of the same. Fig. 5 is a rear elevation ot the same. Fig. 6 is a perspective Fig. 7 is a side view showing the track levers and a slide operated thereby.

Referring specifically to the drawings, 6 indicates the rails and 7 are lever boxes or housings located beside the same. lVires 8 are connected at opposite ends to slides 33, working in the boxes 7 on opposite sides of the crossing, the wires at one end passing aroundV pulleys 9 to reverse the direction o'l, movement. These boxes may be made in sections and located a considerable distance .trom the crossing, and the wires will be carried on the guide pulleys 9 to proper position tor operating the gates. The wires are connected to levers 10 on cross shafts 12 extending between the gate boxes 13, and on one side is a rod 11 between the levers 10, which operates both shafts when a wire 8 is pulled either way. A series of trip levers 29, sutlicient in number and location to be at all times engaged by one or more of the wheels ot a train passing thereover, are pivoted in the box 7 and project at their lower ends into notches or recesses 34 in the slide 33, the recesses being so located and of such size that the levers will swing Jfreely when turned in one direction, but when turned in the other direction will strike the bar 33 and shift the same length- Wise, thereby pulling on the corresponding rope 8. The trip levers and boxes are so arranged that when a train is passing in one direction the levers in the box at one side of the track will operate, and when passing in. the other direction the levers in the box at the opposite rail. or side of the track will operate.

15 are turn buckles for adjusting the length of the cables 8.

The tilting masts of the gates are indicated at 14, pivoted at 17 in the gate boxes 13 and geared together as indicated at 1G 'for simultaneo-us operation over the roadway and side-walk. One mast 14 has attached thereto a lever 18 connected by a link; 19 to a lever 20 on the end ot the shaft 12 projecting into the bottom of the gate box, and when said shaft is turned the levers are swung accordingly and the masts are raised or lowered.

The signal device consists of a bell 28 fastened to the front ot' the gate box and sounded by hammers 24 and 24 which are pivoted to the box. AOne of these hammers, 24, is operated by its lower end tripping over the teeth of a ratchet 23, and the other is operated by a dog 26 tripping over the teeth of another and opposite ratchet 23a and striking a pin 25 at the lower end ot' the hammer 2te. The ratchets 23 and V23a are mounted on a shaft 35 which is turned by a segment 21 meshing with a gear 22 on said shaft 35, the segment 21 being mounted on the shaft 12, to which a weight 27 is attached for the purpose of returning all the parts to their original position after each operation.

By the means described when the wheels of the train pass over each trip lever 29 at one side of the crossing it presses the same down and shifts the slide 33 which pulls the cable S and lowers the gates. After the train` passes the crossing and reaches the corresponding levers at the other side of the crossing the latter are pushed down to shift the slide and pull the cable the other way, thereby raising the gates. The turn of the shaft 12 causes the bell to sound as soon as the gates begin to lower.

l/Vhat we claim as new is:

1. ln an automatic railway gate, the combination ot a tilting gate bar, a shaft, operating connections between the shaft and the gate bar, trip levers beside the track rails, at opposite sides ot the crossing, slides mounted for lengthwise movement beside the rails, and having` recesses into which t-lie levers project, to shift the saine when the levers are operated, and cable connections between the slides and the shaft.

2. In an automatic railway gate, the coinbination of a tilting gate bar, a rock shaft eX- tending across the railway track, operating connect-ions between the shaft and the gate bar, casings located beside the track rails on opposite sides of the crossing, a series of trip levers mounted in said casings and projecting in position to be struck by wheels on the track, slides mounted for lengthwise movement in the boxes and having recesses into which the levers project, said recesses being` shaped to permit the levers to swing in one direction without operating` the slides, and to shift the slides when swung in the other direction, and cable connections between the slides and the rock shaft.

n testimony whereof, we do'aiflx our signatures in presence of two witnesses.
