RAILWAY-GATE.

SPECIFICATION forming part of Letters Patent No. 625,740, dated May 30, 1899. Application filed December 30, 1898. Serial'No. 700,685. (No model.)

To all whont it may concern.-

Be it known that we, LYMAN CARRIER and E810 Z. GLOW, citizens of the United States of America, residing at Joliet, in the county of Will and State of Illinois, have invented certain new and useful Improvements in Railway-Gates, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain improvements inrailway-gates for use in closing a street and sidewalk to travel while a railwaytrain is crossing them, and relates more particularly to the class of gates wherein a gatearm is used to be elevated and lowered across the street and sidewalk, which improvements are fully set forth andexplained in the following specification and claim, reference being had to the accompanying drawings, and the letters and figures of reference thereon, in which- Figure 1 is a prspective view'of the gates as they would appearlet down across the roadway and sidewalk to close them to travel. Fig. 2 is a plan View of a short section of a link belt, having a section of a cable attached thereto; and Fig. 3 is a side View of the upper end of one of the posts and of the inner ends of a gate-bar and sidewalk-gate bar pivotally connected to said post and with each other and of a link belt for operating said gates, the broken lines showing the position of said gate-bars as they would appear raised to open the roadway and sidewalk to travel.

Referring to the drawings, A represents the four gate-arms, having their inner ends .pivotally connected to the posts D neartheir upper ends by means of a short shaft S, having a sprocket-wheel O secured on its outer end, and provided near their outer ends with depending rod-supports J for maintaining them in a horizontal position when let down. B are sidewalk-gate arms having their inner ends pivotally connected to said posts near their upper end adjacent to the inner ends of the gate-arms A and connected therewith through the medium of segmentgearsarranged, respectively, one on each inner end of said gate-arms A and B and in mesh with each other, as shown more particularly in Fig. 3, so that when the gate-arms A are elevated and lowered they will simultaneously elevate and lower the sidewalk-gate arms B, as shown in broken lines in Fig. 3. F is a steel-wire cable for operating said gatearms by engaging the sprocket-wheels O of the gate-arms A, said cable having sections of a link belt L inserted where it engages said sprocket-wheels. Said cable is one continuous length and engages and operates all four of the gate-arms simultaneously. The two ends of the cable attach to the lever E, one at either side of its fulcrum G, so that movement of said lever in either direction will turn the gate-arn1s either up or down.

Fig. 1 shows a pair of gate-arms placed one at either side of therailroad-track R and connected by the cable F, which is arranged to pass underneath said track, as shown in the broken lines. Said cable F has one end attached to the lower end of leverE and passes from thence under pulleys 2 and 5, around pulley 7, under pulley 12, up over sprocketwheel 0, under pulleys 11 and 8, up over pul- Iey 10, and in contact with sprocket-wheel C, under pulleys 9 and 6, up over sprocketwheel 0 under pulleys 4 and 3, up over pul ley 13, and in contact with sprocket-wheel C under pulley 1 to lever E, to which it is attached between its fulcrum and outer end, by means of which arrangement and connection with the gate-arms they may all be simultaneously turned eithernp or down by operating said lever forward and backward. The reverse position of said lever F. from that shown in Fig. 1 would raise all the gate-arms up, as shown in broken lines in Fig. 3.

The cable F, it will be observed, is ar ranged to pass under the roadway and railway, so as to be out of'the wayand be protected from injury or interference of anything passing along the roadway or railway, as is shown. in Fig. l, the broken lines showing howthe cable passes under the railway, so as to connect the gate-bars at either side of the railway, the whole forming a very effective and durable system of gate-bars for such purpose.

Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is as follows, to wit:

The combination of the posts, D, gate-arms E at opposite sides of its fulcrum substan- A, pivoted to said posts, sprocket-Wheels O, tially as described.
