Application filed 0ctober28, 1924. Serial No. 746,392.
The present invention appertains to a railroad crossing gate and has for its prime object to provide such a gate which is adapted to be automatically operated in any desired manner by a train.
Another very important object of the invention is to provide a structure of this nature having an extremely simple and efiicient construction which is not liable to get out of order.
A still further very important object of the invention is to provide an apparatus of this nature which may be cheaply installed and yet be durable, strong, and reliable.
With the above and numerous other objects in View as will appear as the description progresses, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawing: Figure 1 is an elevation of the gate showing the samein a raised position with portions broken away,
Figure 2 is a detail transverse section taken substantially on the line 2-2 of Fig ure 1 looking in the direction of the arrows.
Referring now to the drawing indetail' wherein like numerals of reference indicate corresponding parts throughout the several views the gate embodying the present invention consists of a gate proper 7 slidable vertically in a frame 8. This frame 8 is an inverted U-shaped structure with its extremities embedded in the cross road 5. The side rails of the frame are preferably formed of chan nel iron or the like in order that the ends of the gate rails may extend into the channels thereof and be thus guided. A cable 9 is attached to the top of the gate by any suitable means as at 10 and is trained over a pulley 11 journaled in the intermediate portion of the top or head of the frame 8 andthen is trained over a'similar pulley 12 which is journaled in one corner of the frame. This cable is then led down in an outer channel of one side portion of the frame 8 which is substantially H-shaped as 1s shown to advantage in Figure 2. A
bracket B is mounted adjacent the bottom bodiment of the invention has been described I in detail, it will be understood that I do not wish to be limited to the particular con- 7 struction set forth, since various changes in the form, material, proportions, and arrangement of parts, and in the details of construction may be resorted to Without departing from the spirit and scope of the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, what.
I claim as new is:
A gate of the character described, comprising an upright frame structure including a pair of spaced parallel side rails each of substantially H shaped cross-sectional design and positioned with the channel side of one opposing that of the other and a cross head beam connecting the upper ends of said rails, a gate body positioned between said rails having laterally projecting members slidably positioned in the opposed channel of said rails, av pair of pulleys upon said head beam one centrally thereof and the other adjacent one end, a pulley member secured to a side rail adjacent the lower end thereof, and an operating cable connected at one end to the central portion of said gate and passing upwardly and over said pair ofpulleys downwardly to and beneath said last mentioned pulley to a source of power, the downward portion of the cable being located within the outer channel of one of the side rails.
In testimony whereof I ailix my signature.
ROY E. SPRATLEN.
