Application filed May 31, 1217.

To all whom it may concern:

Be it known that I, LEMUEL L. Hoot), a citizen of the United States, residing at \Vichita Falls, in the county of Wichita and State of Texas, have invented certain new and useful Improvements in Crossing-Grates, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in crossing gates and it is an object of the invention to provide a device of this general character having novel and improved mechanism coacting therewith whereby the gate is caused to assume a closed position automatically and under the' influence of rolling stock.

It is also an object of the invention to provide a gate of this general character includ ing novel and improved means whereby said gate is caused to automatically assume an open or elevated position after the rolling stock has passed over the crossing.

The invention consists in the details of a construction and in the combination and arrangement of the several parts of my improved crossing gate whereby certain important advantages are attained and the device is rendered simpler, less expensive-and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the bet ter understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is an elevational view illustrating crossing gates and an operating means therefor arranged in accordance with an embodiment of my invention, the second position of the gates being indicated by dotted lines;

Fig. 2 is a fragmentary view in top plan illustrating certain details of the invention as herein included;

Fig. 3 is an enlarged-elevational view with portions broken away illustrating a pair of gates as positioned at one s1de of the track- Fig. 4 is an enlarged fragmentary view in elevation illustrating the construction at one end portion of the operating bar, as herein embodied;

Fig. 5 is a view in top plan of the structure as disclosed in Fig. 4;

Specification of Letters Patent.

Patented Sept. 18, 191?.

Serial No. 171,987.

Fig. 6 is a sectional view taken substantially on the line 6(3 of Fig. +2; and

Fig. 7 is a horizontal sectional view taken through the lower portion of the structure as disclosed in Fig. 6 with certain of the coacting members in top plan.

As disclosed in the accompanying drawings T denotes a trackway having positioned at opposite sides thereof the longitudinally 3 caused to assume a closed or lowered position.

Extending longitudinally of the rail of the track-way T positioned adjacent the outer side thereof is an elongated bar B extending a predetermined distance beyond the location of the gates G. The bar 13 has its upper longitudinal edge normally supported a distance above the top of the adjacent rail of the trackway through the medium of the rock arms 3. Each of the shafts a is rota;

tably supported by the clamping members 5 held in applied position to the base flanges of the adjacent rail of the trackway by the clamping bolts 6. The shaft 4 is capable of free rotation and the armfi is constantly urged upwardly to maintain the upper marginal portion of the bar 13 normally above the adjacent rail of the traclzway through the medium of the spring 7 encircling the intermediate portion of the shaft 4e and having one end suitably anchored to the shaft el and its opposite end bearing against a wall of the recess 8 produced in the inner face of a member 5. Both of the members are provided with the recesses 8 and which recesses are adapted to aline when the members 5 are in appliedpositionp The recesses 8 afi'ord an enlarged bore to accommodate the spring 7, hereinbefore referred to.. The limit a of upward movement of the arm 3 and more particularly of the bar B is controlled by an outstanding pin 9 carried by the bar B and-which contacts with the lower or under edge of the arm 3 in a manner which is believed to be clearly apparent to those skilled in the art to which my present invention appertains. Each of the shafts 1 is operatively engaged with the bar B through the medium of the rock arm 10 whereby itwill be perceived that as the bar B is depressed by contact with the upper edge thereof the wheels of the rolling stock or shafts 1 will be rotated or rocked sufficiently to cause the gates G to assume the closed or lowered position, 7

as indicated by dotted lines in Fig. 1 and full lines in Fig. 2.

One end portion of the bar B has its upper margin arranged 011 a predetermined downward incline, as indicated at 11 for a purpose which is believed to be self-evident while the opposite end portion has coacting therewith a supplemental bar B. The up per marginal portion of the bar B is also disposed on a downward incline as indicated at 12. The bar B is supported by the rock arms 14 which are mounted in a manner identical as has been set forth relative to each of the arms 3 with the exception that the arms'la are disposed upwardly on an inward incline and in a direction reverse to the direction of inclination of the rock arms 3. The bar B is in longitudinal alinement with the bar B and has secured to its outer face at the inner end portion thereofa plate l 15 which extends beyond the inner end por- V about three hundred feet in length in order tion of the bar B and overlies the outer face of the adjacent end portion of the bar tively connected through the medium of the slot 16 and the pin 17.

The inclined portion 11 of the bar B and the supplemental bar B may be of any desired length although I have found in practice that the same should be preferably to obtain the best results. It will also be self-evident that by the use of the supplemental bar B the gates may be caused to lower or assume a closed position irrespective of the direction in which a train may be traveling.

From the foregoing description, it is thought to be obvious that a crossing gate constructed in accordance with my IIIVQII'. tion is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may Copies 0! this patent may be obtained for be assembled, and it will also be obvious.

that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation'of-the position upon movement of the bar in the opposite direction, 'means for normally maintaining the bar at the limit of its movement in one direction, a supplemental bar coacting with one end portion of the first named bar, said supplemental bar being mounted for longitudinal and vertical movements and when depressed moving in a direction toward the first named bar and one end portion of the supplemental bar being provided with a longitudinally dis posed slot and a laterally directed member carried by the first named bar and seated within the slot of the supplementalbar said slot being of a length in excess of the extent of longitudinal movements of the bars.

:2. In combination with a rail of a trackway, clamping members engaged with said rail in longitudinally spaced relation, rock shafts supported by said clamping members, an upstanding rock arm carried by each of the rock shafts, a bar disposed longitudinally of the rail and operatively engaged with the rock arms, means coacting with the rock shafts for constantly urging the rock arms upwardly, a swinging gate posi tioned adjacent the rail, and anyoperative connection betweenrthe bar and the gate whereby said gate is caused to move into either an open or closed position under the influence of the bar, and an outstanding pin carried by the bar and contacting with one of the rock arms for limiting the upward movement of the bar. v i

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
