l llllllllllllil JB El/672,367 ii/$623M 004m W ,1 ul fio r110 UNITED STATES PATENT ()FFrEO DANIEL HAMMAN, OF BEASON, ILLINOIS.

RAI LROAD-GATE.

SPECIFICATION forming part of Letters Patent No. 244,052, dated July 12, 1881.

Application filed September 15, 1880. (No model.)

To all whom it may concern Be it known that I, DANIEL HAMMAN, a citizen of the United States, residing at Beason, in the county of Logan and State of lilinois, have invented a new and useful Improvement in Railroad Cattle-Grates, of which the following is a specification.

My invention relates to a new and useful improvement in railroad cattle-gates for which I obtained a patent in the United States, No.

228,459, bearing date June 8, 1880.

The object of my improvement is to reverse the action of the gate, causing it to fall across the tie to which all themechanism is attached,

I5 as by this method is insured a safe operation of the gate when it falls toward the approaching train. I attain this object by the device illustrated in the accompanying drawings, in which Figure 1 is an elevation, showing the gate in vertical position as applied. Fig. 2 is a plan of the same, showing the gate in horizontal position.

' Similar letters refer to similar parts th roughout the several views.

A are the rails.

B is the tie, which may be made of wood or iron, and of suitable dimensions, required to attach all of the parts contained in my device.

O is a standard, erected at and resting on one end of the tie B, to which is pivoted, at a, the segment-gear D, lon gitudinally with the track. The segment-gear D has a lower projection, E, provided with an elongated hole,

in which one end of the lever F rests. Said lever passes down and at right angles to the segment-gear under one of the rails, and terminating in a point at b, a portion of which to the tie with bolts or spikes, as shown. in Fig. 2. The segment-gear D is further provided with an arm, G, extending longitudinally, and having a weight, H, attached thereto. It is obvious that this arm G and its weight H may be cast with the segment-gearD, forming a part thereof, or they may be made separate and attached together, as desired.

rests'under the opposite rail, and is fastened I is an oscillating shaft, hung in suitable bearings attached to the side of the tie B, below the level of its upper surface, said shaft being provided with a series of iron bars or pickets, i i t, which form the gate, said shaft being further provided with a gear-wheel, J, which operates in conjunction with the segment-gear D.

The rail nearest the standard is formed of two sections, of the usual length of rails now in use, joined directly over the center of the tie B by links d on either side, and bolted together through the web of the rails in such a manner as to admit of a vertical motion of said rails, the extreme ends of the sections resting in railway-chairs.

In order to prevent the operating-rail from moving out of place I connect it with the opposite rail, which is firmly fastened to the ties by bars 0, similar to those used in joining the rails of switches.

The operation is as follows: When a train of cars approaches the gate from either direction upon the track the wheels strike the elevated rail, depressing it, carrying down the lever F and the short end of the segmentgear D, consequently raising its opposite end, to which the weight is attached, and cansing the shaft I to partially rotate, through the medium of the gear-wheel J, to throw the bars or pickets i into a horizontal position below the upper surface of the rails, out of the way of the train. After the train has passed the bars or pickets i are thrown up into a vertical position by the action of the weight H upon the outer end of the segment-gear D.

It will be seen by reference to the drawings that the pickets t are bent in such a manner at their lower ends that they may be attached to the rock-shaft on the side when they stand in a vertical position, and are offset somewhat from said shaft, so as to allow the pickets to lie down flat upon the tie B. By this it will be seen that the pickets have the same time to fall when the train is approaching from the direction in which the gate falls that they have when approaching from the opposite direction. 95 Thus it is difficult for the train to strike tEe 5 what I claim as new, and desire to secure by pickets when approaching it from either direcand gate having the pinion J, of the internal tion, as the gate is always operated before it segment-gear, D, having weight directly at- 10 can be reached by the train. tached thereto, as shown and described.

Having thus fully described my invention, i D ANIEL HAMMAN Letters Patent, is- Witnesses:
