SPECIFICATION forming part of Letters Patent No. 583,041, dated May 25, 1897. Application filed February 11, 1897. Serial No. 622,904. (No model.)

To all whom it may concern:

Be it known that we, ALFRED E. GATHER- COLE and WILLIAM RILEY, citizens of the United States, residing in Paterson, county of Passaic, and State of New Jersey, have invented certain new and useful Improvements in Railway-Gates; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters .of reference marked thereon, which form a part of this specification.

This invention relates to improvements in railway-crossing gates; and its object is to provide such gates on each side of the track of simple, strong, and durable construction, and which gates may be readily and quickly operatedthat is to say, raised and lowered simultaneously from one place and by one person.

The invention consists in the various novel details of construction and combination of the several parts, substantially as will be hereinafter more fully described, and finally embodied in the clauses of theclaim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the several views, Figure 1 is a front elevation of a complete gate and its operating mechanism with the pavementand foundation shown in section; Fig. 2, a top plan View of Fig. 1 with certain portions removed and clearly illustrating the connection of the operating mechanism with the gates on each side of the crossing; Fig. 3, an enlarged detail View in elevation of one of the gates and its operating mechanism, certain parts being broken away and others shown in section to better illustrate the nature of our said invention; and Fig. 4:, a top plan View of Fig. 3, the cover of the standard being removed.

In said drawings, a and I) represent two standards provided with suitable bearings for the shafts e f, on which the gates e and f, respectively, are securely mounted. The

said bearings consist of plumber-blocks r, resting on the ledges of shelves 1", projecting inwardly from the sides of the standard and provided with elongated slots 0*, penetrated by the bolts W, by means of which latter the said plumber-blocks are adj ustably arranged, and as the said plumber-blocks form the bearings for the shafts carrying the gates the said shafts and gates along with the plumberblocks can be shifted so that the outer ends of said gates are brought in alinement with each other, should said gates become warped by change of temperature or other climatic exposures, as will be manifest.

The standards are arranged upon suitable foundations a b, surrounding catch-basins a 19 communicating with each other through the channels 0 and d, connecting about midway between the standards, and having their bottoms inclined toward their respective catch-basins, as clearly shown. On the shaft f is secured a crank-arm g, pivotally connected through the verticallyarranged link g with one arm of angle-lever g pivoted, as at 9 to and within the standard I). The other arm of said angle-lever is pivotally connected with the upwardly-projecting portion of the rod g having its free end pivoted to one arm of lever 9 fulcrumed as at g, the other arm of which lever is pivotally connected with rod g which in turn operates the shaft 6 of the gate 6 through angle-lever g pivoted as at g, link and arm g. The mechanism last mentioned in connection with gate 6 is identical with that of gate f, except that the various parts are inversely arranged.

To the upwardly-projecting portion of the rod 9* is secured one end of connecting-rod h, the other end of which is pivotally connected to the free end of crank it, mounted on shaft 71/ which latter has its bearings in the bracket z" of the frame a 011 said shaft is secured a gear-wheel 7L3, meshing into gear-wheel 72. on the parallel shaft 7L5, which latter is operated through the crank-handle 72 carrying the latch h adapted to engage notches 7L8 of the arc Won the frame 71, as clearly shown. The

gates e and f on the other side of the crossing are operated from the shaft 71?.

The depending crank-arm h on the other end of said shaft is pivotally connected to one end of the horizontal]y-arranged rod 07., (parallel to the connecting-rod 71,) the other end of which rod is pivoted to one arm of the angle-lever a, fulcrumed as at 71 The other arm of said angle-lever is pivotally connected, through rod a with the angle-lever n fulcrumed as at a 71, which latter in turn operates the gates f and e in precisely the same manner as above described in connection with the gates f and c. On one side of the standard I) is arranged a plate 0, adapted, with its outwardly-projecting portions 0, (see Figs. 3 and 4,) to limit the upward movement of the gate f. On the inside of said standard is arranged a plate 0 furnishing an extra thickness for the bearings of the bolts 0 which latter penetrate the said plate and also the side of the standard I) and bear with their nuts against the outside of the plate 0. Said bolts are surrounded by spiral spring 0", bearing against the plate 0 and the heads 0 of the bolts, respectively.

It will be understood that similar springcontrolled striking-plates are arranged on each of the standards to limit the upward movement of their respective gates. v lVhen the gates are to be operated from a tower, the frame 1', carryin g the operating mechanism, is placed in said tower. The crank-arms 7L are done away with and are substituted by the crank-arms m, pivotally connected, through the vertical rod 112/, (which may be of any desired length,) with the angle-lever m fulcru med as at m and pivotally connected with the rod 72., as will be manifest.

In operation when the lever 7L is moved from right to left the gear-wheels 7L and its are operated, thus moving the crank-arm from right to left and through the connectingrod h, operating the rod 9 which in turn, through the connectionsheretofore described, moves the gates fand e upward. Simultaneously the gates f and e are moved upward through the connection illustrated in Fig. 2, as will be manifest.

Ve do not intend to limit ourselves to the precise construction shown and described, as various alterations can be made without changing the scope of our invention; but

Vhat we claim as new, and desire to secure by Letters Patent, is-

1. The combination with a standard, of a shaft in said standard and traversing the same, a plate provided at each end with projecting portions loosely arranged on one side of said standard, and a series of spring-controlled bolts penetrating said plate and the side of said standard, substantially as and for the purposes described.
