GATE.

Specification of Letters Patent.

Patented Sept. 14, 1909.

Application filed February 17, 1909. Serial No. 478,388.

To all whom it may concern:

Be it known that I, THADDEUS S. HARP, a citizen of the United States, residing at Rifle, in the county of Garfield and State of Colorado, have invented a new and useful Gate, of which the following is a specification.

The invention relates to improvements in gates.

The object of the present invention is to improve the construction of gravity-acting slid ing gates, equipped with tiltable track bars, and to provide a simple and comparatively inexpensive gate of this character in which the end bars will remain continually in a vertical position irrespective of the position of the tiltable rails and strike the abutments of the frame squarely, whereby twisting and straining of the gate is entirely eliminated.

Another object of the invention is to provide a gate of this character, adapted to be conveniently operated at a distance from either side of it by a person on horse back or in a vehicle without dismounting.

With these and other objects in View, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim here to appended it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a perspective view of a gate, constructed in accordance with this invention. Fig. 2 is a detail view. illustrating the arrangement of the inner ends of the tiltable track bars.

Like numerals of reference designate corresponding parts in allthe figures of the drawing.

The gate proper comprises in its construction front and rear vertical end bars 1 and 2 and upper horizontal rails 3, pivotally se cured at their terminals between the vertical end bars 1 and 2 by pivots l. The end bars, which are arranged in pairs, are spaced apart to receive the rails 3 and are equipped at their upper ends with rollers or wheels 5, arranged to run upon track bars 6 and 7, whereby the gate is suspended therefrom. The track bars, which are pivoted at their inner ends by suitable fastening devices 8, are tiltable by the operating mechanism hereinafter described, and when it is desired to open the gate, the front tiltable track bar is raised from a horizontal position, thereby carrying with it the gate, which, through gravity, slides down the incline carried by the front track bar and opens. When the front track bar is raised, the end bars of the gate maintain a constant vertical position, but the rails 3 swing upward and assume an inclined position, and through their pivotal connection with the end bars of the gate, permit either end of the same to be raised. By pivotally connecting the rails 3 with the end bars of the gate and permitting the latter to remain in a perpendicular position, the end bars of the gate in both the opening and 010s ing movement strike the abutting portions of the supporting frame squarely and avoid any twisting or straining of the gate. per portions of the front and rear end bars 1 and 2 of the gate are provided at intervals with perforations 9, adapted to receive the pivots 10 of the rollers or wheels 5 and enabling the gate to be adjusted vertically to arrange it the desired distance above the ground so as to pass over snow and other obstructions.

The frame-work for supporting the gate includes front, rear and intermediate uprights 11, 12 and 13, connected. by a horizontal top bar 141: and provided with spaced vertical strips 15, 16 and 17. The track bars 6 are pivoted between the intermediate upright 13 and the strip or bar 17, and when the gate is opened or closed, they are supported in a horizontal position by front and rear spacing blocks 18 and 19. The rails 3 of the gate also pass between the intermediate upright 13 and the strip 17. The track bars extend forwardly and rearwardly beyond the uprights 11 and 12, and their outer terminals are connected with ropes 20 and 21, extending upwardly to upper front and rear pulleys 22 and 23 and downwardly and inwardly therefrom to intermediate or centrally arranged pulleys 24: and 25. The ropes 20 and 21 extend upward from the centrally arranged pulleys, and are provided with upwardly diverging branches 26 and 27, which are connected with two sets of operating levers 28 and 29. The operating levers are fulcrumed on a bar 30, arranged at right angles to the horizontal track bars 14 and extending from opposite sides of the frame-work and supported by inclined braces 31. The operating levers are located at the The upside faces of the bars 30and in practice will extend a suitable distance from the opposite of the rear rope 21 and are oscillated to raise the rear trackbar 7 for closing. the gate. Instead of rope any other suitable connection maybe employed for connecting the levers with the tiltable track bars.

The gate is equipped at its ends with front and rear latches 82 33., pivoted between the front rear end bars of the gate, and arranged to engage front and rear horinonta l-1y disposedpins' and 35, extending across the spacebetweenthe ha rs l5 and 16; and the adjacent uprights ll and I2 and forming keepers, The latches are provided with shoulders to engage the keepers and are beveled in advance of the engaging shoulders, so that they will be automatically lifted through contact with the keepers. YVhe'n either end of the gate is lifted, the latch thereof is disengaged from the keeper and the gate is free to move down the incline formed by the pivotal track bars.

Having thus fully described my invention,- what I claim as new and desire to secure by 7 Letters Patent, is:-.

The combination with at supporting frame, of oppositely extending tiltable track bars pivoted at their adjacent inner ends to the frame and normally arranged in a horizontal position andhaving their outer ends extended beyond the frame, a gate composed of end bars slidably suspended fromthe 1 track bars and normally arranged in a verti ranged at the center of the upper portion of' the frame and extending in opposite d'irections therefrom and operatin in planes at right angles to the gate, inner and outer gi'iidesm'ou'nted on the frame and arranged at different elevations, the inner guidesbeing located belo'jyv' the operating levers, and the outer guides beingfllocated above the outer portions of thetrack bars, and flexible connections' secured to the outer" ends of the track bars and extending upwardly therefrom to theouter' guides and then downwardly and inwardly to the lower guides, said flexible connections being connected at their inner ends tothe operating levers. r

In testimony, that I claim the foregoing as my own, I have hereto aflixed signature in the presence of two witnesses.
