RAI LROAD-GATE.

SPECIFICATION forming part of Letters Patent No. 484,256, dated October 1 1, 1892.

Application iled June 24, 1892. Serial No. 437,845. (No model.)

To all whom it may concern.-

Be it known that I, COLUMBUS A. SNIDER, of Greencastle, county of Putnam, and State of Indiana, have invented certain new and useful Improvements in Railroad-Gates; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyingdrawings, in which like figures refer to like parts.

My invention relates to new and useful iniproveinents in the construction and method of operating railway-gates and to one of that class wherein the gate is automatically lowered as the train approaches and raised in a similar manner after the train has passed, the movement of the train operating upon suitable mechanism, which in turn operates to raise or lower the gates, and it will be understood from the following description.

In the drawings, Figure 1 is a plan View of a railway-track centrally broken away, showing a single gate and mechanism for operating it. Fig. 2 is an elevation of the same. Fig. 3 is a longitudinal sectional View through the operating mechanism. Fig. 4 is a crosssectional view on the line Fig. 3. Fig. 5 is a longitudinal section through the hollow gate-base on the line e z, Fig. 6. Fig. 6 is a cross-sectional view through the same on the line y y, Fig. 7. Fig. 7 is a vertical section on the line 'Le tu, Fig. (i.

In detail, 1 represents a track laid on suitable ties or sleepers 2 in Ythe ordinary mauner, 3 being a hollow box or casing, which is preferably sunk in the ground beneath the ties, its top extending upon a line with the base of the rails, and thebox consisting of a main chamber 4 and an auxiliary chamber 5. In the sides of the main chamber are formed grooves 6, and in these grooves slides, which are formed on vthe sides of the sliding box 7, are adapted tofmove, this box being supported normally at the top of the chamber by a coiled spring 8 and having on one end a series of teeth 9, which engage with the teeth on a pinion 10, rigidly secured to the shaft or axle 11, having bearings in the Walls of the casing 3 and extending through to the auxiliary chamber 5, in which is a grooved ilywheel 12, rigidly mounted on the axle 11, as shown in Fig. 4.

13 are levers pivoted at theirouter ends to the rail 1 or to blocks formed thereon, their inner ends being pivoted to rods 14, these being pivoted together at their lower ends and normally resting on the movable partition 15, which is supported in the box 7 near its top. This partition works in guides 16, formed in one side of the box, and at its outer end has an opening in which the horizontal rod 17 is adapted to engage. Rod 17 works loosely in the covered box 13, which forms an extension to the main casing 3, and at its outer end has an extension 19, which is carried up to a line with the base of the rails and has a slot 2O in its top. The outer en d of the rod A17 is pivoted to a link 21,which is in turn pivoted within the box 19 at 22.

.43 is a be1l-crank lever, also pivoted at 22, its upper end extending through the slot 2O and above the rail and its lower end engag-4 ing with the link 21. A spring 23, secured to its end and to the end of the box, operates to hold the lever 43 against the link.

24 is a coiled spring working between a partition 25 in the box 18 and the collar 26, formed on the rod 17, which operates against the tension of the coiled spring 23, thus holding the rod and its connections in the position shown in Fig. 3.

27 are rods pivoted to the operatinglevers 13 a little on one side of their centers and extending down into cylinders 23, which are sunk in the ground, the rods having pistons on their ends, which rest on the tops of the coiled springs 29, which operate to hold the levers in a lifted position, as shown.

To the iiy-wheel 12 in the auxiliary chainber 5 of`tl1e casing 3 is connected a wire or cord 30, which extends up above the ground and is carried on pulleys 31 to the base of t-he gate that is to be operated, which may be at any convenient distance-say from three huudred to seven hundred feet. It enters the gato-base 33 at its lower end and is there carried around the pulley 34 and extending upward is connected to a projection on the weighted end 35 of the gate. The gate itself is of any convenientlength and is pivoted at 36 within the base, so that the longer end of the gate is slightly heavier than the weighted end and adapted to lean slightly forward of a vertical line when open. 37 is a support for the weighted end, which is pivoted in brackets ICO 38 and at its upper end notched and adapted to engage with the under side of the Weighted end of the gate, as shown in Fig. 7, and retain it in a lifted position, thus holding the gate in a lowered position,as shown in dotted lincsin Fig. 5. The lower end of the support is pivoted to a connecting-rod 39, which passes outside of the gate-base and through aslot in the rail and is connected on the inner side to a shifting-lever 40. The pivoted end of1 this shifting-lever stands out a slight distance on the inside of the rail and its outer end fits up close to the rail and is pivoted to a short arm -or rod working through an opening in the rail and within the box 41, set at one side,

a spring 42 being coiled around the rod and retained in place bya pin,thus normally holdingrr the outer end of the lever snugly against the inside of the rail, as shown inFig. 6,

The gate herein shown is to be operated only by a train upon the right, and for operation by a train coming in the opposite direction a duplication of the operating mechanism would be required, and this would also be needed ,in a case where double tracks are used or two or more gates required, the oper ation of the gate itself remaining precisely the same.v Upon a train approaching from the right the tread of the Wheels will run upon and depress the operatingdevers 13 and their inner ends operating on the rods 14. These in turn bearing on the partition 15 of the sliding box will carry the same downward against the tension of the coiled spring 8, and the teeth on the side of the box, engaging with lthe pinion 10 on the shaft 11, will rotate the same, and with it the {ly-wheel 12, thus releasing the tension of the operating wire or cord 30. This then being slack within the base of the gate, the gate by its gravity will fall, the weight at its opposite end being such as to make the movement of the gate easy, and upon its falling into a horizontal line the pivoted supporting-lever 37 will engage with the under side of the weighted end and retain it in a horizontal position until the train has reached the crossing, when the flange on the car-wheels Will force inward the end of the releasing-lever 40, which, through its connecting-rod 39, will shift the lower end of the lever 37, thereby moving the upper end outward, releasing the Weighted end of the gate. At the time the train has entirely passed over the operating-levers they will be forced upward by the coiled springs 29 and the sliding box 7 will beforced upward by its spring 8, its teeth operating on the pinion 10 to turn the shaft 11 and the llywheel 12 backward until the operating cord or wire is taut, and the slidingbox will be held in its partly-lifted position through the lightening l of the wire until the moment when the gate is released by the lever 37, when the tension of the coiled spring 8, bearing against the under side of the sliding box, will operate to force the box 7 entirely up and to turn the grooved wheel and'operate through the connecting wire or cord to lift the gate into the position shown in Fig. 5.

It will be understood by reference to Fig. 3 that the opening in the partition 15 of the sliding box is in line with the bent end of the horizontal rod 17, and when the box is carried downward it releases it from engagement with such rod, and upon Aits returning to its normal or raised position it then engages with the end of the rod, the opening in the partition being large enough always to accomplish this, and should a train come from the opposite or left-hand side, Where it would not be desirable to have the gate operate, the tread of the wheels would engage with the pivoted lever 17, forcing it downward, its end engaging with the crank 2l, throwing it to the left, and with it`the rod 17, thus operating to pull out the partition 15 of the sliding box, so that as the train passes over the operating-levers 13 the rods 14 would be forced down into the sliding box without moving or operating it at all.

Although, as here shown, the mechanism for operating my improved gate is generally placed beneath the ties, it is obvious that the construction may be so changed as to allow it to be placed outside the ties and on a level with the ground; or it may be placed in the present position, the rails being set on longitudinal sleepers instead ofthe ordinary cross- 1 ties.
