BRIDGE-GATE.

SPECIFICATION forming part of Letters Patent No. 460,797, dated October 6, 1891. Application filed April 8, 1891. Serial No. 388,106. (No model.)

T0 til whom it 70m/y concern.-

Be 1t known that we, MICHAEL IIIMMES and JACOB HIMMns, citizens of the United States ot' America, residing at Chicago, in the county of Cook and Statel of Illinois, have invented certain new and useful Improvements in Bridge-Gates, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to automatic bridgegates, and more particularly to a gate adapted for use in connection with a swinging or pivoted bridge, and so arranged that it is opened and closed by reason of the movement of the bridge.

The object of this invention is to provide a device of this character of simple and durable construction.

The invention consists in the features of construction and combinations ot` parts, hereinafter fully described, and specifically claimed. l In the accompanying drawings,illustrating our invention, Figure l is a side elevation of a bridge and abutment constructed in accordance with our invention. Fig. 2 is an end elevation of the bridge. Fig. 3 is a side elevation of a part of one of the gate-arms and its post, and Fig. 4 is a cross-section of the abutment, gate-arms, and devices for operating same.

Referring` to said drawings, A indicates the bridge; l,the pier therefor; 3,the abutment, and 2 friction-rollers upon the abutment for supporting said bridge when closed.

In the construction shown two posts 3 and 4 are located in the middle ot' a double roadway, and swinging gate-arms 5 and 6 are pivoted upon said gate-posts and are adapted to swing on opposite sides of the same across the roadways. In Fig. 3 the post 3 and arm 5 are shown in detail. The said arm is provided with a hub 7 and a counter-balance end S. The hub 7 is pivoted between the sides 9 of the upper end of the post, and a link or connecting-piece l() is pivoted to the said hub away from its center, and extends downward through the hollow post 3 and is connected with a vibrating lever ll. In said Fig. 3 the arm 5 and link l0 are shown in full lines in the position they will assume when the lever Il is depressed; but it is obvious that when the lever is elevated it will raise t-he link, and thereby turn the hub 7 on its pivot and elevate t-he arm 5, as shown in dotted lines in said Fig. 3. A support or standard l2, having a bifurcated upper end, is arranged to support the outer end of the gate-arm when it swings downwardly. To strengthen said gate arm and provide a more effectual barrier, a supplemental arm 13 is pivoted at one end to the post and is pivotally connected by a bar li to the outer end portion of the gate-arm. A bracket l5 is secured to said support or standard l2, and is located that the end of the supplemental arm 13 will rest thereon when the gate-arm is in a horizontal position. The links l0 are pivoted to the lever ll at a point between its ends, and at one end said lever is pivoted in a bearing 1G, secured to the abutment. The other or f ree end of the lever is forked, as shown at 17, and is located in position to be engaged bya cambar18, secured to the bridge. Thehighest part of said cam-bar is located in the middle ofthe bridge, so that when the bridge is closed the lever is thrown to the upward limit of its movement, and therebylifts the gatearmsas shown in Fig.' l and indotted lines Fig. It willot' course be seen that if the bridge swings in either direction the cam-bar will depress the end of the lever l1, and thereby drawthe gate-arms down by means of the links l0.

C indicates a bell supported by a springarm 19, which is located in the path of a pro` jection 20, mounted upon the bridge, so that -as said bridge swings open the spring-arm will be agitated, and thus ring the bell.

It is obvious that by slight change in the construction of certain parts the devices could be arranged for operation with a' single roadway or single gate-arm.

We claim as our invention- The combination, substantially as hereinbesupported upon a post upon the abutment In testimony whereof we affix our signatures having a counterbalanoed end, a link pivoted n presence of two witnesses. to said gate-arm away from its center7 and a Vibrating lever pivoted at one end to the abut- MICHAEL HIMMES. 5 ment and pivoted between its ends to said JACOB HIMMES.
