In the accompanying drawings similar letters of reference refer to similar parts.

. Figure l is a sectional view showing the rela tive position of the parts when the gates are opened. Fig. 2 is a top plan view of the same. Fig. 3 is a side elevation of the vertical shaft carrying the gates and the plain bevel-gear by which the same are operated. Fig. 4 is a front elevation of the same. Fig. 5 is a side elevation of the bevel gear-wheels and the arms by which they are operated. Fig. 6 is a top View of the guideway and traveling bar by which the gates may be operated when hinged together in the center. Fig. '7 is a perspective view of one of the operating-levers.

' Fig. 8 is a front view of the upper portion of one of said levers, showing the method of engagement with the shaft. Figs. 9 and 10 are plan views of the faces of the oscillating-clutch engagement of the operating-levers with the shaft. Figs. 11 and 12 are perspective views of the latch mechanism for engaging and releasing the gates Figs. 13, 14, and 15 are detail views of the latching device.

The gates A and A are carried by two vertical shafts B and B, j ournaled upon supporting-posts C and O, sunk in the ground upon the sides of the track. To the middle of the shaft B there is attached by means of a thumbbolt a bevel gear-wheel b, which meshes with a correspondingly partially geared wheel 79, carried upon a shaft b j ournaled in a box 17 secured to the vertical post, and a box I), mounted upon the vertical shaft B. To the shaft 19 carrying the partially-geared wheel I), there is attached a spacing-bar 11 having bolted to the free ends thereof bars 12 and b", to which are attached the wires which communicate with and are attached to the various operating-levers, hereinafter more fully described, the wires heretofore referred to being attached to sliding bolts passing through holes in the upturned ends of the bars Z9 and b" and preferably cushioned by coiled springs. To the partially-bevel-geared wheel I) there is securely bolted a lever 12 which is T-shaped in form, carrying rods 1) and N, which pass through loops b and b on the end of the spacing-bar 11 one of which rods has mounted upon ita coiled spring I), which acts as a spring-check against sudden impulse.

Bolted to the tops of the vertical shafts B and B are crank-levers b and b, coupled by means of a connecting-rod 19 which causes the oppositely-disposed overlapping gatesto move in opposite directions, dividing the resistance caused by the air and permitting of their more rapid operation.

When the gates are hinged together in the center, as shown in Fig. 6, there is provided a trackway D, attached to the top of the gateframe, and a post at the side of the track, which acts as a guide for the traveling bar (1, bolted at its other end to the gate. When this form is employed, the shaft B is done away with, together with the crank arms or levers b b" and the connecting-bar Z2 The operation of the vertical shaft B causes the gates to swing out and in, folding one upon the other, and vice versa.

On the side of the track upon which there is located the shaft B and at a suitable distance from the gates there are provided posts E and E, upon each of which there is journaled in any suitable manner a shaft 6, to the outer end of which there is bolted'the weighted bar a, to the ends of which are attached wires b and Wand b and b. Upon the inner end of each shaft and loosely journaled thereon is the operating-lever e having at its lower end a roller 6 to engage the wheels of the cars as they pass along the track. The upper end of the depending lever c is pro vided with an extension or lug 6 having engagement with a corresponding lug c upon a sleeve e secured to the shaft 6 by means of a thumb-bolt, thus forming a clutch which becomes operative only when the depending operating-lever has been raised to the proper height and prevents any sudden jar or strain which might be caused by the rapid contact of the car-wheels therewith. To the end of the weighted bar e, attached to the shaft journaled on the post E, there are attached the connecting-wires b and I), which cross and are attached to the ends of the spacingbar Z2 The purpose of crossing these wires is to reverse the motion, so thata car passing one of the depending operating-levers would cause the gates to open, and passing the other depending operating-arm would cause the motion to be reversed and the gates closed.

For the purposeofprovidingapositivelatch, by means of which the gates are held open while the cars are passing through and are in turn released when the last car shall have passed through, I provide the mechanism shown in Figs. Hand 12. On opposite'sides of the gate-supporting frame and adjacent to the track are planted posts F, F, and F and posts F, F, and F and journaled in or upon these posts are shaftsfandf and shafts)" and f to which, on the inner ends thereof and next to the rail, there are bolted depending operating levers or arms f and f and f andf, coupled together by connecting-rods f and f to engage with and be carried upward by the rim of the car-wheels. Upon the outer ends of the shafts f and f are looselyjournaled the oscillating clutch-levers f and f similar in construction to those heretofore described. Mounted upon the brace f ,connecting the posts F and F there is bolted an L-shaped frame f, to which there is pivotally attached the latch f. To the lever f there is pivotally attached the actuating-bar f, having a sliding engagement with the latch f by means of the projectionf and held in position by means of a lipf, turned down upon the supportingframe f. To the outer end of the latch f there is attached a U shaped spring, the other end of which is engaged with the L-shaped frame f The oscillating clutch-levers are connected by means of the wire f through which the power is transmitted to the latching device.

It will be observed that each of the operative levers and spacing-bars has the oscillating-clutch connection with the shaft upon which it is mounted, and by means of the sleeves, adjustable on the shaft, they can be so set as to permit the levers to become operative only in one direction and to take up the jar of any sudden contact.

In operation, the gates being closed and the car passing along the track, the wheels thereof come in contact with the first depending opcrating-lever and cause it to pass up and over the rim of the wheel, the motion being transmitted by means of the spacing-bar to the bevel gear-wheels, which cause the gates to swing open. One of them engages with the spring latching device, and they are thus held open until the last car passes the connecting bars or rods on the opposite side, when the same drop down, transmitting the motion to and releasing the spring-catch and disengaging the gates, which are again closed by means of the weighted spacing-bar swinging down into its normal position and transmitting the motion through the Wires to the bevel gear-wheels.

Having thus fully described my invention, what I desire to claim and secure by Letters Patent is 1. In a mine trap-door, the combination of oppositely-disposed gates mounted upon vertical shafts, provided with crank-levers coupled together, depending oscillating clutchlevers journaled at the side of the track, and upon both sides of the gates, a bevel-gear train communicating with one of the vertical shafts, and Wires connecting the gear-train with the oscillating clutch-levers, substantially as described and for the purpose set forth.

2. In a mine trap-door, the combination of oppositely-disposed gates mounted upon vertical shafts coupled together, with depending oscillating clutch-levers journaled at the side of the track, and upon both sides of the gates, a bevel-gear train communicating with one of the vertical shafts, wires connecting the gear-train with the oscillating clutch-levers, a spring-actuated latching device mounted at the side of the track, and means for disengaging the same, substantially as described and for the purpose set forth.

3. In a mine trap-door, the combination of a gate mounted upon a vertical shaft with the depending oscillating clutch-levers jon rnaled at the side of the track, and upon both sides of the gate, a bevel-gear train communicating with the vertical shaft, and wires connecting the gear-train with the oscillating levers, substantially as described andfor the purpose set forth.

4. In a mine trap-door, the combination of a gate mounted upon a vertical shaft with the depending oscillating clutch-levers journaled at the side of the track, and upon both sides of the gate, a bevel-gear train communicating with the vertical shaft, wires connecting the gear-train with the oscillating clutch-levers, a spring-actuated latching device mounted at the side of the track, and means for disengaging the same, substantially as described and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
