' .To all, whom it may concern.-

Be it known that 1, JOHN V. BAIRD, a citizen of the United States, residing at Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in Gates, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in gates, being designed as an improvement upon the gate for which I received Letters Patent December 14, 1880, No. 235,489; and it has for its objects, first, to so connect two sliding gates with a crank actuated by the wheels of a vehicle as that the movement of the crank will be gradually ap plied to opening and closing the gates, so as to prevent jarring or jerking, and the consequent shattering of the connections; and, second, to provide for actuating the latch, so as to disengage it from the gate to which it hooks by the same action which opens the gates.

In the accompanying drawings, forming a part of this specification, and on which similar letters of reference indicate the same or corresponding features, Figure 1 represents a side elevation of my improved gate and the operating mechanism, Fig. 2, a detached view of a portion of the middle rail of one of the gates, showing the actuating-rod and latch-rod in connection therewith; Fig. 3, views showing the lower gate-rail and the track in section, and the roller and a side elevation of the roller, the track, and one of the connectingplates; Fig. 4, a view of a portion of the operating-shaft, showing the longer-and shorter pitmen, and Fig. 5 a view of one of the gates and the actuating mechanism.

The letter A designates a timber of suitable dimensions embedded in the ground, to which are secured the posts 13 and O, the lower ends of which may extend into the ground, as seen in dotted lines, and upon this timber A is suitably secured a metallic track, D, consisting of a bar placed edgewise and secured to the posts B, (one only of which is shown,) and at intervals to the timber by staples E. Also secured to the posts B and O are guide-strips F, preferably of metal. The posts B are further provided with bumpers G, each consisting of a bolt having an enlarged head, and fitted lon the actuating-rod gitudinally in a hole in the post, and having a spiral spring, H, around it, as shown, for the purpose of arresting the gates when thrown open. One of the gates has a like bumper to ease the coming together.

Each gate may be of any desired pattern, and in this instance they consist of uprights I and J, to which are secured suitable longitudinal beams, K and K and K, to the latter of which are attached metallic plates L, having elongated depressions M formed on the inner face thereof, for the purpose of receiving the spindles of the-support-ing-rollers N.

These rollers travel upon the track D, and are grooved so as to ensure their remaining on the track. g

The beam K is longitudinally slotted and provided with correspondinglyslotted metallic plates O, which afford additional strength,

and with spiral springs 1, between which is fitted one end of the actuatingrod Q, which is bent down after passing through the slot, so as to prevent its dislodgment. The function of the springs is to yieldingly connect these rods with the gates, so that any quick movement imparted to them in the manner presently to appear will not be positively communicated to the gates, the springs giving to the movements of the rods until the inertia of the gates is overcome. This feature is fognd to be of practical importance, as it prevents the undue-destruction or strain of the several parts, and admits of the gates being heavier and of more substantial character, as the trouble arising in overcoming the inertia is avoided by the presence of the springs. The beams K are provided also with metallicplates It, secured to them by cars S, and serving the function of guiding the levers, to be presently described, preventing them from unduly swaying laterally.

On one ofthe beams,K,is pi votall y mounted a latch, T, of bell-crank form, the hook end of which is adapted to engage with the post J of t-heopposite gate. Thislatch is connected with a rod, U, which in turn is connected with Q, whereby, when the latter is operated to open the gate, the latch is tipped on its pivot and made to disengage the opposite gate.

The uprights I of the gates are provided .5, the crank of the direction of the arrow with bifurcated brackets V, which embrace the guide-strips F and act to maintain the vertical'position of the gates, while the lower ends'of the uprights J are provided with feet lV,whieh, when the gates are closed, enter the hasp X, located at the meeting-point of the gates, this being for the purpose of additionally holding the gates in line when in a closed position. i

The letterYdesignates the actuating-levers, consisting, preferably, of metallic bars pivotall y mounted in bearings secured to the timber A, and connected at their upper ends with the actuating-rods Q, already described. These levers pass through the space between the beams K and the plates. R, and are guided, as above described. To one of them, below its pivotal point, is connected a long pitman, Z, while to the other, above its pivotal point, is connected the shorter pitman, Z, and these pitmen are thus connectedwith a crank of an operatingshaft, a, disposed at right angles to the traveling of the gates, and provided with sections 1), connected with the shaft proper by universal joints 0 of any approved construction. These joints admit of the shaft proper being located at a' different elevation and out of di rect line with the sections b, as in the case of a hill, where the gate is located. These sections 1) are provided with pinions d which mesh with similar pinions, e, mounted upon crankshafts f, having bearings located in the path of the vehicle-wheels.

The shafts f have each two cranksone for opening and the other for closing the gates. \Vhen the wheels ride over the crank f fi going in the direction of the arrow, as' seen in Fig. shaft a will move in the shown in Fig. 1, and the upper ends of the levers Y will be drawn from each other, and through the actuatingrods Q the gates will be opened, the rod U serving to unhook the latch T, in the manner above described.

When the vehicle shall have passed through the opening, and a crank corresponding to f is actuated by the wheels, the levers will be moved in the reverse brought together.

It is obvious that instead of the two springs Pin each slot, one spring may be used, and the actuating-rod Q passed between the coils of the same.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1.' The combination, with two gates having supporting-rollers, the track below the fixed posts, and the guiding-strips, to which the gates are slidingly connected, of the pivoted levers having one end flexibly connected with the gates through the medium of a spring,the operating-shaft, and the pitmen connecting its crank with the other end of said levers, and the wheel crank-shaft geared to the operatingshaft.

direction and the gates 2. The combination, with the fixed posts, the track, and the guide strips, the gates mounted upon rollers fittedto said track and connected to the strips by brackets, and having each a slotted beam, and springs fitted to said slots, of the pivoted levers, the operating-rods connected to the levers and to the gates through said springs, the operatingshaft, and the pitmen connecting its crank with the said levers, and the wheel crank-shaft geared to the operating-shaft.

.3. The combination,with two gates mounted to open and close from and toward each other, of a wheel crank-shaft, and an operating-shaft geared to the wheel-shaft and provided with a crank, andtwo levers respectively connected with the respective gates by a rod, and a spring to form a yielding connection, and two pitmen connecting with the operatingshaft and with the said leversone below and the other above the pivotal points of the levers.

4. The combination, with a gate having a slotted beam and a spring or springs contained within the slot, of a pivoted lever, and an actuating-rod connected to said lever at one end and fitted through said slot and adapted to work against the said spring or springs at the other end, whereby the lever through the rod and springs is yieldingly connected withv the gate, and operating mechanism to operate the lever.

5. The combination,with two gates mounted to open and close from and toward each other, of the pivoted levers through a spring, a latch connected with the actuating-rod, the operating-shaft, the pitmen connected with one lever above the pivotal point and with the other below the pivotal point, and the wheel crank-shaft geared to the operati ng-shaft.

6. The combination, with the two gates, a track upon which they are mounted, and connections to sustain them vertically, of the pivoted levers connected with the gates through a spring, a latch connected with one of said levers, the actuating-shaft, the pitmen connecting its crank with said lever and the wheel crank-shaft.

7. The combination, with the gate carrying a pivoted latch, and having a slotted beam containing aspiring or springs, of the pivoted lever, the actuating-rod connecting it with the springs, and a rod connecting the latch with the actuating-rod.

8. The combination, with a sliding gate, of a pivoted lever connected thereto through a spring, and a pivoted latch carried by the gate and connected to the lever.

In testimony whereof I affix my signature in presence of two witnesses.
