AHILTON MELROSE LOOKETT, or HENDERSON-,Entraneur i SPECIFICATION forming part ef'Lettes Patent No. r701,905, dated 'J'une 1o, 1902.

Application filed March. 1902*.

'lheobject of thevpresent invention is to'V improve the construction of sliding gates and to provide a simple, inexpensive, and efficient one of great strength and durability, adapted to be readily operated at a distance from either side of it to enable it to be opened and closed without dismounting from a horse or leaving a vehicle.

The invention consists in the` construction` and novel combination and arrangement of ner of locking the latter.

parts, hereinafter fully described, illustrated in the accompanying drawings, and pointe out in theclaims hereto appended.

In the drawings, Figure 1 ,is a perspective,`

view of a gate constructed in accordance with this invention. Fig. 2 is an enlarged detail sectional view illustrating the manner of4 mounting the vertically-movable locking-bar and guide.

1 designates a sliding gate mounted onsuitable rollers or Wheels 2 and 3 and arranged between uprights 4 andprovidedwithfan extension 5, composed of 'extensions of'two of the barsv or rails of the gate and arrangedin slots or openings`6'and'7 of a postor support 8. The arm vorezrtension of the gate'is arranged between rollers or wheels"9v andlO, 1ocated above the upper rail or bar and below the lower rail or bar, and these, rails or bars are connected at their rear ends by a suitable cross-piece. The arm or extensionV 5*"of the gate assists in counterbalancing the same, and it relieves the gate of strain and prevents the gate from sagging when closed.

The bars or uprights 4 have mounted upon them a vertical guide 11, composed ot' bars Fig. 3 isf a similar View illustrati ing the arrangement of the guide-pulleys for.

spaced apart and having'theopening or space between them' arranged at right angles to theA opening or space between the posts or upthe upper guide-bars form a frame for supporting the gate and the locking mechanism thereof. The posts or uprights 4 are spaced 'apart by suitable blocksA vl2 and 13, having openings in which is mounted a guide-tube .14, and the latter receives thelower gate-engaging portion 15 of a verticallymovab1e combined guide and locking bar 15. The upper portion of the vertically-movable bar 15 extends through ka guide-opening 16 at the upper ends of the bars 11. The verticallymovable bar is providedlbetween its ends with aflange or. stop y17, andLit is enlarged Iabove the same vtoreceive a pivot or pin,l 18

for connecting it to tlep'inner adjacent ends of a pair of operating-levers 19', which are fulcrumed ,between their ends on movable supports 20, adapted to swing outward and inward as the levers are operated. The operating-levers are provided at their` inner ends with perforations or ears receiving .the

arms of the levers, whereby the iexible `con'a nection is pulled upon and actuates the gate. When the operating-levers are pulled downward, the gate is actuated with sufflcientfforce Lto'carry it' to its openposition, and in com pleting its mvementin' 4either *directionit draws Athe innerarms of the'joperatinglevers downward, returning thejoperating-levers to theiLiniti'al position.A Tlrefiiexible connes tion, which may be constructed in anyfdesiied manner, extends downwardfat one side of tlfe guide-tube 14 and passes betweenva pair of guide-pulleys 23, mounted 'betweenltflie .posts or uprights 4.and .locateddirectly above the gate. The oscillating supports 2O consist of bars or uprights pivoted at their lower ends by pins 24 in bifurcations of short posts 25, and the `upper ends of the bars or uprights rights 4, and the lower posts or uprights and rpin or pivot 18, and the'said operating-le# 2O are provided with suitable brackets 26, having upwardly-extending arms, between which the operating-levers are pivoted. The bars or supports 20 swing inward and outward as the levers are moved upward and downward.

The gate is provided at its upper edge with front and rear recesses 27 and 28, forming sockets and adapted to be engaged by the lower end of the vertically-movable combined guide and locking-bar, as illustrated in Fig. 3 of the accompanying drawings. The combined guide and locking-bar engages the rear notch or recess to hold the gate in its closed position, and it similarly engages the front notch or recess to retain the gate in its open position.

It will be seen that the gate is exceedingly simple and inexpensive in construction, that it is easily operated to open and close it at a distance from either side of it, and that it is securely locked in its open and closed positions.

l. The combination of a frame orsupport, a gate, a vertically-movable locking-bar guided on the frame and arranged to engage the gate, supporting-bars pivotally mounted at opposite sides of the gate, operating-levers fulcrumed on the supporting-bars and connected to the vertically-movable locking-bar, and means for connecting the latter with the gate, substantially as described.

2. The combination of a frame or support, a

sliding gate, a vertically-movable locking-bar mounted on the frame or support and located above and adapted to engage the gate at the limit of its movement, the supporting-bars pivotally mounted at opposite sides of the gate, the operating-levers fulcrumed on the supporting-bars and connected with the Verticaily-movable bar, and a flexible connection extending from the gate to the operatinglevers, substantially as described.

3. The combination of a frame or support havinga gate-receiving opening and provided with upper bars spaced apart to form an opening, a gate arranged to slide in the lower gatereceiving opening, a pair of pulleys located above the gate, a vertically-movable lockingbar and guide mounted on the frame or support, a tube or casing receiving the lower portion of the locking-bar and guide, operatinglevers extending into the upper openings of the frame or support and connected to the said locking-bar and guide, movable fulcrums supporting the operating-levers, and a flexible connection extending between the said pulleys and connected with the gate and with the voperating-levers, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixed my si gnature in the presence of two witnesses.
