GATE.

SPECIFICATION forming part of Letters Patent N o. 575,942, dated January 26, 1897. Application iiled August 22, 1896. Serial No. 603,616. (No model.)

To all whom it Jncty concern,.-

Be it known that I, AMON W. CHILCOTT, ot Stewartsville, in the county of De Kalb and State of Missouri, have invented a new and useful Improvement in Gates, of which the followingis a full, clear, and exact description.

The object of my invention is to provide a gate which may be adjusted vertically in such manner as to raise the swinging or free end of the gate any desired distance from the ground, thereby permitting of the passage of small stock and likewise enabling the gate to be readily operated in the presence of snowi drifts or like obstructions.

Another object of the invention is to provide a means for operating the gate whereby the said gate will pass a dead-center in opening and'closing and will be locked in either its opened or closed position, from either of which positions it may be released and swung by suitable levers placed at opposite sides of the road or path crossed by the gate.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the gures.

Figure 1 is a plan view of the gate closed. Fig. 2 is a front elevation of the gate, illustrating in dotted lines the manner in which it may be vertically adjusted. Fig. 3 is a plan View of the gate partially open. Fig. 4 is a side elevation of the supports for the devices employed to operate the gate, the gate being closed 5 and Fig. 5 is a view similar to Fig. 4, illustrating the gate as partially open.

The gate used with this invention consists of a rear or swing bar 10, afront bar 11,longitudinal top and bottom bars 12, and any desired number of intermediate bars 13, the longitudinal bars being pivotally connected to the front and the swing bars, and the longitudinal bars are also pivotally attached to a Vertical bar 14, which is located at or near the center of the gate, and any number of these vertical or transverse bars may be elnployed.

On the central transverse bar 14, at a central point thereon, a lever 15 is fulcrumed,

and two links 16 and 17 are pivotally attached to said lever at about an equal distance from.

its fulcrum, and the outer ends of the links 16 and 17 are pivotally connected, one to the upper rear corner port-ion of the gate and the other to the forward lower portion thereof. One end of the lever 15 is provided with a handle, as is particularly shown in Fig. 2, wherebythe lever may be readily grasped and manipulated, and by drawing the handle portion of the lever upward, as shown in dotted lilies in Fig. 2, the links 16 and 17 will be made to draw on the end portions of the gate in such manner as to raise the free end a desired distance above the ground, enabling stock to pass under the gate and likewise enabling the gate to be carried over any obstructions that may be in its path.

The gate is provided at top and bottom with knuckles 1S at its rear end, and the knuckles of the gate cooperate or engage with knuckles 19, which aresecured to a swing-post 20, and the longitudinal members of the gate extend beyond its front transverse bar 11 and engage with the face of a keeper-post 21, the gate being adapted to open and close'at one side of the swing and keeper posts only.

Upon that face of the gate which is within the line of the keeper and swing posts a bracket 22 is secured, and the said bracket supports a bar 23,which is likewise rigidly attached to the gate at its center, and the bar 23, together with the bracket 22, form virtually a triangle, the bar 23 extending from the center of the gate in direction of its rear or swing end, yet. diverging therefrom. Alink 24 is pivotally connected with the bracket-bar 23 of the gate, and this link 24ispivotally attached to an arm a of a crank-shaft 25,which crank-shaft is provided with a second arm a', the latter arm being at a right angle to the arm a, and the said crank-shaftis fulcrumed upon a supporting-beam 26, extending from theswing-post 2O of the gate to a second post 36 in line with the said swing-post, yet atan l angle to the gate when said gate is closed. In fact, the supporting-beam 26 is at a right-angle to the surface over which the gate'will stand when in its closed position, as illustrated particularly in Fig. 1.

At the outside of the swing-post 20 alever 27 is fulcrumed at one of its ends, and this IOO lever is in the nature of a bar, being quite heavy, and is connected by a link 28, comprising, preferably, two members, as shown in Fig. 1,with the arm a of the crank-shaft. The link 28 is a locking-link, and when straightened out, as shown in Figs. l and Lt, willhold the gate in either its closed or in its open position.

Two links 29 and 30 are pivoted on the lever 27 near the end which is connected with the locking-link 28. The links 29 and 30 are made to diverge at their upper ends, the link 30 being connected with one end of a shifting bar or arm 3l, the said shifting bar or arm being fulcrumed upon the swing-post 2O of the gate between a bracket 32 and a post, and between the said bracket and the post a suitable recess is provided, having` a more or less convexed bottom 33, permitting of a rocking motion of the aforesaid shifting-arm. The link 29 is connected in like manner with one end of a second shifting-arm 34, which is ful-` crumed between the auxiliary post 36 and a bracket 35,secured to the said post,the bottom wall 37 of the recess between the bracket and post being likewise more or less convexed or curved, as shown in Fig. 4C, and a pendent link 38, rope, chain, or their equivalents is attached to the free ends of the shifting-arms.- Both of the shifting-arms are parallel with the road or path which is to be closed by the gate, and one of the arms extends to the front and the other to the rear of the gate.

In operation, the gate being closed, when the gate is approached from eitherside it is simply necessary to draw down the free end of the shifting-arm at that side of the gate,where upon the crank-arm a of the crank-shaftwill be raised au d likewise its opposing arm a', and the latter arm will raise the lock-link 28, and consequently the locking-lever 27, and the crank-arm a in being elevated will,throu gh the medium of the link 24, throw the gate in its direction and the momentum of the gate will carry it beyond its center, causingthe bracket arm or bar 23 to pass over or across the locking-lever 27, and as the gate is brought parallel with the aforesaid locking-lever the arm a of the crank-shaft will be carried to ahorizontal position and the opposing crank a to a vertical downwardly -extending posit-ion, straightening the locki ng-link 28 and causing the gate to be firmly locked open. After the personA has passed through the gate-openi'ng, by drawing downward upon the shifting-arm at the opposite side of the gate the same ac- Jfionv takes place, namely, both crank-arms a and d are raised and the gate is carried by its momentum over its center, and at that time the link 24 will straighten itself, forcing the gate to a perfectly-closed position and drawing the crank-arms a and a to their normal position, straightening the locking-link 28 and causing the gate to be locked in its said closed position, as is illustrated particularly in Figs. l and l.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination of a gate, a locking-le ver fulcrumed at one end to a support independent of the gate, a crank-shaft having crank-arms at angles to one another, a link connection between one of the crank-arms and the locking-lever,a second link connected with the opposite crank-arm and pivotally attached to an extension from the gate, and means for raising and lowering the lock-le- Ver, substantially as described.

2. The combination of agate, a locking-lever fulcrumed at one end to a support independent of the gate, a crank-shaft having crank-arms at angles to one another, a link connection between one of the crank-arms and the locking-lever, a second link connected with the opposite crank-arm and pivotally attached to an extension from the gate, and means for raising and lowering the lock-le- Ver, the said extension being attached to the central portion of the gate at the side at which the gate opens, projecting in direction of the crank-shaft and diverging from the gate at that end whichis connected with the link, and for the purpose set forth.

' 3. The combination of a swing-gate, a locklever, a crank-shaft having one of its crankarms in link connection withV an extension from the gate, a locking-link connecting the locklever with the second arm ofy thecrankshaft, shifting-arms extending beyond opposite sides of the gate, supports for the said arms, and a link connection between the two arms and the lock-lever at a point near where the said lever is connected with the lockinglink, asl and for the purpose set forth.

4. The combination of apivotally-mounted gate, a lock-lever, a duplex crank-shaft, one arm of which is connected with the lock-le-Y ver, means for swinging the lock-lever, and

a connection between the second arm of the crank-shaft and the gate, substantially as described.
