SPECIFICATION forming part of Letters Patent No. 641,464., dated January 16, 1 90d. Application filed December 20, 1898- Serial Nb. 699,797, (N6 model.)

To all whom it may concern.-

Be it known that I, SIMON L. MoOoLLocn, a citizen of the United States, residing at Wheeling, in the county of Ohio and State of West Virginia, have invented or discovered a new and useful Improvement in Gates, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a plan view of my improved gate and its operating mechanism,the gate bein g shown as closed across the roadway. Fig. 2 is a similar view showing the gate open. Fig. 3 is an elevation of Fig. 2. Fig. 4: is a plan view of the operating cables and sheaves, illustrating an arrangement whereby the levers operate in a direction toward the gate. Fig. 5 is a perspective detail view of a portion of the gate, showing the latch in engagement as operated to unlatch by upward movement of the outer end of the locking-bar and in the position of the gate when closed across the roadway. Fig. 6 is a similar View from the opposite side of the gate, the gate being retained in its open position, as in Fig. 2, and the locking-bar in engagement as operated to unlatch by downward movement of the outer end of the locking-bar. Fig. 7 is a view similar to Fig. 3 looking in the direction of the arrow at of Fig. 1. Fig. 8 is a perspective detail View illustrating the operative mechanism by which the locking-bar is raised and lowered and the gate swung on its hinges. Fig. 8 is a detail viewillustrating a modified construction of the end of the latch-operatin g lever. Fig. 9 is a detail View, in front elevation, of the operating-lever and its connec tions. Fig. 10 is a perspective View of the same parts shownin areversed position. Fig. 11 is a detail plan view of the adjustable hinge-strap for the lower hinge. Fig. 12 is a detail view illustrating a modified form of Referring to the drawings, 2 is the post upon which the gate 3 is hung by upper and lower hinges 4 and 5 The upper hinge is formed, preferably, of abracket 6', secured to the gate and pivotally mounted on a hingehook projecting outwardly from the post 2. The lower hinge is similar in construction and likewise projects outwardly from the post, but somewhat beyond the upper hinge. Both hinge-hooks are attached to that side of the hinge-post toward which the gate opens, and the lower hook is set nearer to the front of the post and slightly farther out from its face than the upper one, thus occupying a position vertically beyond the upper hook intermediate between the right-angled positions of the gate when opened or closed. By this means the gate will swing by gravity toward one side or other after passing such intermediate position. The strap 7 of the lower hinge is adjustably secured on the under side of the gate-frame by bolts passing through slots 8, thereby permitting the strap to be set in or out to provide for subsequent adjustment of the gate after setting in case of sagging or warping of the frame.

It will be 'seen that I employ a post 9,10- cated across the roadway, and another post 10 at right angles to such post, against which posts the gate is swung in either the closed or open position and secured by latches, as shall be hereinafter more fully described.

Upon the post 9 is a rigid latch 11, preferably slotted for adjustment on the retaining-bolts and provided with an upper retaining-shoulder 11', adapted to engage the end of a locking-bar 12, pivoted at 13 in the frame of the gate, the locking-bar in such case operating to unlatch by upward movement. Upon the other post 10 is a pivoted latch 14, mounted in a keeper 15, permitting upward movement to engage the bar when the gate is swung around to the open position, the keeper preventing dropping of the latch, and the locking-bar 12 in this position operates to unlatch by downward movement. It will be readily understood that these latches may be reversed, if desired, the locking-bar in such case operating in a reverse manner to that described, such change simply involving a reverse action of the operating mechanism hereinafter described.

2 eaiaea Motion is imparted to the locking-bar by means of a bell crank lever 16, pivotally mounted at 17 in a bracket 18, secured to the upper frame of the gate, the projecting lower arm 19 of the lever being connected to bar 12 by intervening connecting-link 20.

A dog or movable attachment 21 is pivoted at 22 to the bracket 18, and its free end 23 engages the upper end of arm 24 of the lever and acts to throw such arm outwardly and arm 16 downwardly by forward movement of the dog, the end 2a of the lever having a limited movement in a recess in the bracket. Lugs 25 on the bracket serve as limiting-stops for the dog in either position of use, as illustrated in Figs. 8 and '10, and when the dog is Withdrawn the upper end of the lever will be thrown against it, and the lower arm 16 will be raised by retractile action of a spring 26, secured to such lower arm and to the bracket, by which the inner end of the locking-bar 12 is raised and the outer end lowered to release it from the latch immediately before closing the gate. In the closed position of the gate the outer end of the locking-bar is first raised from engagement with the latch 11 by downward movement of the inner end of the bar previous to opening the gate, such downward movement being imparted through the downward action of the lever and link 20, operated by pressure of the dog 21 at the commencement of the operation of opening the gate. Movement is imparted to the dog through a pitman connection 27, attached to a crank-arm 28, mounted on a grooved wheel 29, which has a partial rotatory movement, and which in its action around the central bolt 30, secured to post 2, upon which the wheel 29 is mounted, will swing the gate on its hinges to either of the positions illustrated-t1 6., open or closed.

Located along the side of the roadway, preferably in line with the post 2 or in other position, as desired, are the posts 31 32, to which are secured brackets 33, upon which are pivotally mounted the operating grooved wheels 34 35, each wheel being provided with an operating- arm 36 or 36, projecting outwardly toward the middle of the roadway, so as to be within easy reach of the occupant of avehicle. It will be noticed that these arms project forwardly away from the direction of an approaching vehicle, in which case the occupant would operate the wheel by drawing back on the arm, although, as illustrated in Fig. 4, they may be located normally in the reverse position, thus permitting the forward movement of the vehicle to be utilized in turningthewheels. Theseoperating-wheels335 are connected with the wheel 29 by cables 37 38, one of such cables being crossed in order to transmit rotatory motion to wheel 29, always in-the same direction by corresponding outward movement of arms 36 36' or inward movement of such arms when arranged as in Fig. 4.

Referring to the principal figures of the drawings, movement of the wheel 29 when the gate is closed will first act through pitman 27 to throw the dog 21 against the upper end of arm 24, throwing the arm 16 and link 20 downwardly and raising the outer end of bar 12 from engagement with latch 11, releasing the gate, which will then swing around under continued pressure of pitman 27 and dog 21, hearing against the lever and bracket until it is opened. Upon striking against the post 10 the outer end of bar 12, still in a raised position, will ride under pivoted latch 14: and be engaged thereby, thus securing the gate in an open position, when the pivotal end of the crank-arm 28 will have swung around into position (shown in Fig. 2) slightly past the center line of the crank and pitman, thus further locking the parts in position in the manner of a toggle-joint. In this position the lever 28 abuts against any suitable stop, as an extension 39 of p st 2, where it will be held until operated in the reverse position. It will be seen that the other operating-lever 36 will have been thrown into the position shown in Fig. 2 by tension of the cable 38, in which position it will be within easy reach to operate to close the gate after the vehicle has passed through. In such position movement of the wheel 35 in the direction of the arrow will act through cable 36 to reverse the movement of wheel 29, throwing crank-arm outwardly, withdrawing pitman 27, releasing the pressure of the dog, and permitting spring 26 to raise the inner end of bar 12, throwing the outer end down and releasing it from engagement with the latch. Continued movement of the wheels and crank-arm 28 will swing the gate around until it is closed, when it will ride over the latch 11, thus completing the operation.

It will be understood that the pit-man 27 might, if desired, be connected directly to the upper end of arm 2% of the lever; but I preferthe construction shown for the reason that it permits independent action of the lockingbar by simply raising it by hand, as in the ordinary manner. However, if it is desired to make such a connection the end of the lever may be vertically slotted, as shown in Fig. 8, thus permitting such independent upward movement of the bar, while not interfering with the already-described operation through the operating-wheels. The pressure by contact through the dog is also preferable to a direct connection, for the reason that there is freer action and less tendency to bind, owing to the varying angle existing between the pitman and the general direction of movement.

of the arm 24 of the lever. Also, it will be understood that the lever 16 may be made with a downward extension 19, as shown in Fig. 12, having a connection with a sliding locking-bar 12, adapted to engage suitable recesses or hasps secured to the posts 9 and 10.

It will be understood that when the wheels 34: 35 and levers 36 36 are arranged as shown in Fig. at the action of the cables will be re- IIO versed, in which case the shortercable is made straight and the longer one crossed, and the location of the actuating-Wheels, their direction of movement, and the relative arrangement of the posts may be changed by the skilled mechanic to suit varying conditions of use and as circumstances require.

The operation of the gate being in one direction, it is obvious that one of the operating-wheels may be placed nearer to the gate than the other, as the vehicle may be made to approach nearer on that side than on the side toward which the gate swings by such distance as is required for clearance.

The advantages of my invention will be appreciated by those skilled in the art, and it will be found to be applicable to a wide variety of conditions of use with equal advantageas, for instance, on grades, curved roads, &c.

An especial advantage in the use of the grooved sheave-wheels lies in the fact thatthe cables, by reason of always leading off from or onto their peripheries, always exert the greatest possible leverage on such wheels.

Changes and variations may be made in the design, proportions, or general arrangement without departing from my invention, since I do not desire to be limited to the exact construction shown in the drawings, but to include all such changes as within the scope of the invention as embodied in the following claims.
