CHARLES KING, OF NEXV LONDON, OHIO.

BRIDGE-GATE.

SPECIFICATION forming part of Letters Patent No. 409,407, dated August 20, 1889.

Application filed May 3, 1889 To all whom it may concern.-

Be it known that I, CHARLES KING, of New London, in the county of Huron and State of Ohio, have invented a new and Improved Bridge-Gate, of which the following is a full, clear, andexact description.

This invention relates to draw-bridge gates, the object of the invention being to provide a gate which will close automatically upon the opening of the bridge, and conversely, which will be raised to open the way to the bridge upon the closing of the bridge; and to the end named the invention consists in the construction and arrangement of parts, as will be hereinafter fully described, and specifically pointed out in the claim.

' Reference is to be had to the accompanying drawings, forming a partof this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of my improved bridge-gate. Fig. 2 is a side view thereof. Fig. 3 is a cross-sectional view taken on line m a: of Fig. 1, and Fig. 4 is aside view of the. gate.

In the drawings, 10 represents a drawbridge, to the under side of each end of which there is secured a projection 11, which extends beneath the abutment 12. Upon the abutment 12 I mount a rock-shaft 13, which is held by bearings 14 and this rock-shaft I provide with a standard 15, to which there is rigidly connected a bar orframe 16. To the rock-shaft 13 I also connect a downwaidly-extending curved lever 17, which said lever projects into Serial No. 309,431. (No model.)

the path of the bridge projection 11. When the bridge is closed, as represented in Fig. 3, the projection 11 bears against the lever 17 and the bridge bar or barrier is raised to the position in which it is shown in full lines in said Fig. 3; but as the bridge is moved in the direction of the arrow shownin connection therewith in Fig. 1 the projection 11 rides from beneath the lever and the weight of the bridge bar or barrier will carry it to the position in which it is shown in dotted lines in Fig. 3, the extending end of the bar or barrier being at this time supported by a prop 20. IVhen the bridge is again closed,its projection 11 will bear against the lever 17 and said lever will be moved upward to the position shown in full lines, and as the lever so moves the barrier or gate-frame 16 willbe carried to its raised position.

In applying such gates as the one above described it will of course be understood thata gate would be arranged in connection with each end of the bridge.

Having thus described my invention, I claim as new and desire to secure by Letters Patent In a gate for swinging bridges, the combination, with a rock-shaft provided with a standard 15, of a bridge bar or barrier rigidly connected to said standard, a lever rigidly connected to the rock-shaft, and a projection carried by the bridge and arranged to engage the lever, substantially as described.
