GATE.

SPECIFICATION forming part of Letters Patent No. 522,081, dated June 26,1894. Application filed February 2. 1894:. Serial No. 498.910- (NO model.)

To all whom it may concern.-

1 3e it known that LEMIL NEUHAUSER, of Gridley, in the county of McLean and State of Ill1nois, have invented a new and useful Improvement in Gates, of which the following 1s a full, clear, and exact description.

My invention relates to an improvement in gates, and especially to an improvement in that class of gates to be raised and lowered through the medium of levers located at opposlte sides of the gate, and the object'of the invention is to provide a means whereby the openlng and closing mechanism may be ad- ;lusted to balance a long or a short, or a heavy or a light gate, the adjustment being expeditiously and conveniently accomplished, and whereby, owing to the peculiar construction of the operating mechanism it will be impossible for the gate to remain on a center.

Another object of the invention is to com struct the operative mechanism simply, economically and durably and in such a manner that wind, rain, snow or ice will not interfere with its operation, and whereby also the operative mechanism will be noiseless or com paratively so.

Another object of the invention is to construct the operative mechanism in such a manner that when a lever is manipulated to open the gate the latch will be simultaneously disengaged from its keeper, and whereby when the gate is closed the latch will automatically latch itself.

Theinvention 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 figures and letters of'reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a gate having the improvements applied thereto, showing the gate in'closed position in positive lines and in elevated or open position in dotted lines. Fig. 2 is a plan view of the gate in its closed position, and of the operative mechanism connected therewith. Fig. 3 is a detail View of the free end of the gate, illustrating the construction of the latch. Fig. 4 is a vertical section taken practically on the line 4-4 of Fig. 1 and looking in direction of the swing or pivot posts of the gate. Fig. 5 is a section taken horizontally through the gate, practically on the line 5- 5 of Fig. 1, the keeper and pivot posts not being shown. Fig. 6 is a vertical section taken through the gate, practically on the line 66 of Fig; 1, looking in direction of the keeper posts; and Fig. 7 is a horizontal section taken through the gate in itselevated or open position and through the pivot posts thereof, said section being taken substantially on the lines 7-7 of Figs. 1 and 4.

In carrying out the invention. the gate A may be constructed in any approved manner, but at that end which is to be pivoted a heel A is formed at its bottom and rear end.

This heel is angular in construction, and comprises a vertical block 10, which is attached tothe back of the gate at the bottom thereof,

and is utilized as a pivot for the gate, and a bottom block 11, which is secured to the end block and likewise to the bottom portion of the gate, together with a cross bar 11, which is secured to the forward end of the bottom block 11, extending beyond the sides thereof, the cross bar 11 being adapted as a stop, as will be hereinafter set forth, to prevent the gate passing rearward when elevated a predetermined distance only. v

The gate, near its rear or pivot end,'is provided with an auxiliary upright 12, extending usually from its top to its bottom rail, and a crank shaft 13, is journaled in this post, comprisinga body and crank arms at its ends. The said arms are located" at opposite sides of the post and extend indirection of the front of the gate, as shown in Figs. 5 and 7. One crank arm of the crank shaft has pivotally attached to it the rear end of a rod 14, and the other arm has pivotally attached to it a similar rod 15. These two rods are carried forward, one at each side of the gate, through suitable guides, and are pivotally connected with the head 16 of a latch A which latch comprises the said head, which is usually formed with a bow center, as shown in Fig. 5, the straight ends extending beyond opposite sides of the front upright of the gate,

and a shank 17, the said shank comprising members of the shank are secured to the innor face of the front upright of the gate, as shown in Figs. 1 and 3, and above their point of attachment are made to pass through a1? staple 18. When the crank arms of the crank shaft 13 are in their normal or forwardly-extending direction, the head of the latch will be sprung outward or forward by the action.

of its shank, and will enter keepers 19, which may be in the form of recesses, as shown in Fig. 6, and are produced in the inner faces of two keeper posts 0, firmly planted in the ground, one being located at each side of the gate. Thus it will be observed that the latch has a double bearing upon the said keeper posts.

In connection with the keeper posts two parallel pivot or swing posts B, are employed, also firmly fixed in the ground, one being located at each side of the rear portion of the gate; and the rear end of the gate, at its lower edge, is pivoted in these two pivot posts through the medium of a pivot pin 19, which is passed through the heel A of the gate.

Each pivot, or rear post 13, is provided with a longitudinal slot 20, as shown in Fig. 4, and in the forward face of each pivot or rear post a recess 21, is produced, leading into the slots 20, as shown in Fig. 7, into which the cross bars 11 enter when the gate is in its elevated position, thus limiting the movement of the gate in that direction.

Arms 22, are projected upward from the outer faces of the pivot posts of the gate, as is shown in Figs. 2 and 4, and in the upper ends of these cross bars levers 23, are pivoted between their centers and inner ends,the inner ends of the levers being passed through suitable openings in the upper ends of the pivot posts 13, as shown in dotted lines in Fig. 4, whereby they may have movement in said posts, and a handle 24, is usually attached to the outer end of each lever, whereby it may be readily manipulated by a person on foot or mounted. The inner end of each lever 23, is .pivotally attached to a link 25, and these links arecarried downward and pivotally connected with the crank arms of the crank shaft 13.

The gate is balanced through the medium of a balance arm. 26, which is preferably provided with a bifurcated body, as is shown in Fig. 2, which body has its members pivoted at a point about centrally between their ends upon posts 27, located at the rear of the pivot posts of the gate. The forward ends of the members of the body of said balance arm are made to extend into and have movement within the slots 20 in the pivot or rear posts of the gate, and the forward end of each member of the balance arm is connected by a link 28 with an end of the cross bar 11, attached to the heel of the gate. The balancing of the gate, whether said gate be large or small, heavy or light, may readily be accomplished through the medium of a shifting weight 29, which is adj ustably located upon an extension 26 of the body of the balance arm.

In the operation of the gate, when a per son approaches the gate and desires to pass beyond it, the lever 23 approached is simply drawn downward, and in drawing that lever downward, through the medium of the l nk 25 connected with that lever and the 23.851813 ance of the balance arm, the gate will be raised, but before it rises the crank arms of the crank shaft will be turned in a rearward direction, thus drawing the latch from out of its keeper. By giving the leveraquick downward pull, the gate will be carried upward, first by the action of the lever, and :1t W1 ll b0 continued upward to an upright position through the action of the balance arm, while the rearward movement of the gate wlll be stopped by the cross arm 11, enteringthe re cesses 21 in the rear or pivot gate posts,as shown in Fig. 7. After the person haspassed to the other side of the gate, by drawing downward upon the lever at that .side,the gate will he dropped to its normal or closed ;;posr tion, and the latch will automaticallyengage with its keeper. The gate is so perfectly balanced that but a slight downward movement of either of the levers will serve to operate it.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. In a gate the combination with slotted posts, a gate pivoted between the posts, and pivoted levers connected with the gate for operating it, of a bifurcated arm pivoted at the rear of the gate and having its members projecting into the slots of the posts, links connecting the members with the gate, and a counterbalance on the said arm, substantially as described.

2. In a gate, the combination, with posts, a gate pivoted between the posts at onecorner thereof and provided with a cross barat 1135 bottom forward of its pivot point, an arm fulcrumed at the rear of the gate posts, a link connection between the ends of the cross bar and said arm, and a counterbalance weight adj ustably located upon :the said arm, a

jecting ends to engage opposite keepers in the posts between which the gate swings, and rods secured to the latch and to the crank arms of the said shaft, substantially as herein shown and described.

4. The combination, with parallel slotted,

pivot posts having a recess in the inner wall of each slot, a gate, a heel block located at one lower corner of the gate and pivoted between the said posts, and a cross bar attached to the bottom of the gate near its pivoted end and extending beyond opposite sides, of a bifurcated balance arm fulcrumed at the rear of the posts, the members whereof extend into the slots of the posts, links connecting the ends of the balance armwith the ends of the said cross bar, an adjustable weight located upon the balance arm, a rock shaft journaled in the gate in advance of and above its fulcrum, provided with crank arms located at opposite sides of the gate and normally pointing in a forward direction, a latch extending beyond opposite sides of the gate and adapted for engagement with keepers, links connecting the latch with the crank arms of the crank shaft, lift levers, and a link connection between the lift levers and the crank arms of the crank shaft, as and for the purpose set forth.

EMIL NEUHAUSER.
