HENRY CLAY MCCONNELL, OF GRAND RIVER, IOWA.

TRAIN-OPERATED GATE.

Application filed March 8, 1921.

To all whom it may concern:

Be it known that I, HENRY C. MoCoNNELL, a. citizen of the United States, residing at Grand River, in the county 01 Decatur. State of Iowa, have invented a new and useful Train-Operated Gate; and I do hereby de- Clare the following to be a full. clear, and e act description of the invention, such as ll enable others skilled in the art to which it appertains to make and use the same.

The invention relates to train operated gates and has for its object to provide a device of this character which is opened and closed, through the medium of cables connected to pivoted lever, with which levers the train while moving in either direction engages, for closing and opening the gate.

A further object is to provide a train operated gate and cable mechanism for operating the gate, said cable mechanism being operated for closing the gate by pivoted levers located remotely in relation to the gate and on each side thereof and to provide lever and cable means adjacent the gate whereby the gate will be opened immediately the first car or the engine of the train reaches the crossing.

A further object is to provide a lever and cable gate operating mechanism, operated by a train, said mechanism being adapted for use in connection with a pivoted arm gate or a lazy tong gate.

With the above and other objects m view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the'invention may be made within the scope of what claimed without departing from the spirit of the invention.

In the drawings Figure 1 is a view in elevation of the gate and a portion of a railroad track.

Figure 2 is a top plan view of the gate and a portion of the railroad track.

Figure 3 is a sectional view on line 33 of Figure 1.

Figure 1 is a vertical longitudinal sect1onal view through one of the pivoted levers.

Figure 5 is a perspective view of another :form of the invention, showing the use of a pivoted arm gate.

Referring to the drawings, the numeral 1 designates a portion of a railroad track and 2 a crossing. Disposed adjacent one side Specification of Letters Patent.

of the track 1 is a post 8, Which supports the gate 4:. Gate 4 is a lazy-tong gate and has its end 5 pivotally secured as at 6 to brackets carried by the post 3, there being a pin and slot connection 7 and 8 to allow freedom of movement of one of the rear bars of the lazy tong, thereby allowing the lazy tong a whole to fold inwardly. Pivotally secured on lugs 9 carried by supports adjacent the side of the railway 1 and at points remote to the posts 3 and on each side thereof are horizontally movable levers 10, the arms 11 of which are provided with right angled portions 12 which are engaged by a member carried by the engine. and preferably by the cow catcher for operating the mechanism hereinafter described. The levers 10 are returned to a right angled position in relation to the track aliter each gate operation, by means of coiled springs 9 one end of which is secured to the levers at 9 and the other ends to the supports at 9.

By referring to Figures 1 and 2, it will be seen that a train has passed over the track 1 in the direction of the arrow (1 and has rocked the lever 10 on its pivotal point thereby imparting a pull on the wire 13, which wire extends through a conduit 1 1. and over a pulley 15 pivotally mounted on the post 3 and has its end secured as at 16 to a plate 17. Also secured to the plate 17 is an upwardly extending cable 18. which cable passes overa pulley 19 carried by the post 3 and has its end secured as at 20 to the eye of the pin 21 of the lazy tong. Cable 18. at the time that a pull is imparted to the cable 13, is also moved and pulled downwardly and the lazy tong forced open to the position shown in Figure 1. It is obvious that it will be essential to operate and throw the lazy tong gate to the position shown in Figure 1 when a train is mov-- ing in the direction of the arrow Z). To accomplish this result. the cable 22 which passes through the conduit 23 adjacent the side of the track also passes over a pulley 24: carried by the post 3 and has its end connected as at 25 to the plate 17. Thus it will be seen that when the lever 10 is moved by the train, when the train is going in the direction of the arrow 7) that the cable 22- will be moved in such a manner that the cable 18 will be pulled downwardly, thereby opening the lazy tong so that it will eX- tend across the crossing 2. To told the lazy tong gate inwardly a lever 26 is pivoted adjacent the post 3 as at 27 and has an upstanding end 28 which is engaged by the engine when it reaches the crossing. When the lever 26 is rocked in either direction; a pull will be imparted on a cable 29 which passes between the pulleys 30, thence upwardly over the pulley 31 and has its ends secured as at 32 to a. plate 33, which is lo cated adjacent the spaced rollers 34. Connected to the plate 33 and extending over one ofthe rollers 34 and over the pulley 35, is a cable 36, theend of which is secured as at 3'7 to the eye of the bolt 21. Also connected to the plate 33' is a cable 38 which cable passes over one of the pulleys a4: and

has its ends connected'to the plate l7. After the tongs have been moved to the position shown-in Figure'l by the train approaching the crossing, it will be seen that the plate 17 has-been moved'to' a point adjacent pulleys 15 and 24 a-ndthe plate 33 to a point acent the spacedpulleys 34. During the upward'movement of the plate 33, cable 29 is straightened and pivoted lever 26 moved to a right angled position in relation to tlre'railroad track 1', therefore when the train is practically on the crossing '2, it will rock the pivoted lever 26 and'inip'art a pull on the cable 29, cables 36 and 38. This action of the cable 36 will cause the lazy tong gate to-b'e contracted inwardly and at the same time cable 38 will pull'upwardly on the plate 17 and restorethe pivoted levers 10'to normal position at right angles to the track 1. It will be seen that no matter which way the train is going, that'only one lever 10 will be in operative position, and that the other lever will be movedout of position wlie-reit will be engaged by the train.

Referring to" Figure 5-, it will be seen that the cables an'd'22'extend over the rollers 15 and 2t and are secured to the plate 17 and that the cable 26 carried by the restoring lever 26 passes over a pulley 27 and thence over a pulley 28 and has its end securedat 29 to the plate 1'7. It will be seen that after a downward pull has been im'parted to the cable 39 which passes over thepulleys 40 and is connected as at- 411 'to a pivoted gate-412, that said gate" will be pulled downwardly to the horizontally. disposed position shown in Figure 5, and the Figure 0.

plate 17* to the lowered position shown in Pivoted arm 42 is pivoted to the post 3 as at 43, and is provided with theweighted end 44, which weighted end when strain is released on the cable 39 sufficiently counterbalances the arm 42 so that when all strain is released from the cable 39, said armu'nder the influence of the weighted end 44: moves to a vertical position. However to sufiiciently relieve the strain on the cable 29, the engine when it approaches the crossing. engages the lever 26 thereby im parting a. pull on the cable 26. This action causes the plate li' to move upwardly, thereby relieving the strain on the cable 39 and allowing the pivoted arm 40 to pivot upwardly to a substantially vertical position.

From the above it will be seen that a cable controlled and train controlled crossing gate is provided which is simple in construction and positive in its operation and one which may be cheaply constructed.

The invention having been set forth what is claimed as new and useful is-:

A train operated gate, said gate comprising a lazy tong supported by apo'st and horizontally disposed, cables having their ends secured tothe lazy tongs adjacent their rear pivotal point, one o'f'said cables passing rearwa'rdly over a pulley and downwardlyover a pulley and leading to an operating lever adapted to be engaged by a train, the other cable leading away from the supported end of the lazy tongs and over apulley and downwardly and to a lever located remotely from the post and adapted to be operated by a train, a lever pivoted adjacent the post and adapted-to be operated by a train, a cable connected to said last named lever and passing between horizontally disposed pal: leys and upwardly and having its end connected to the rearward'ly extending cable and forming means whereby upon-a down-- ward pull on the same the lazy tongs will be folded.

In testimony whereof I have signedmy name to this'specifi cation in the presence of two subscribing witnesses.
