Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed December 7,1904. Serial No. 235,842.

To a. whom may concern;

Be it known that 1, JAMES DALRYMPLE,L citizen of the United States, residing at Lewisville, in the county of Henry and State of Indiana, have invented a new and useful Gate, of which the following is a specification.

This invention relates to swinging gates, which are also capable of being tilted vertically for passing over obstructions such as accumulations of snow, ice, &c.-in the roadway, and has for its object to provide certain new and useful improvements in the construction of the gate, whereby the tilting of the same is facilitated, and the gate may be supported in various tilted positions in a simple and expeditious manner and at the same time permitted to swing upon its hinges.

lVith these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is a perspective view of a gate embodying the features of the present invention and shown in closed position. Fig. 2 is a side elevation of the gate supported in one of its tiltably- -elevated positions and capable of swinging upon its hinges.

Like characters of reference designate corresponding parts in both figures of the drawings.

The present gate includes longitudinal rails 10, which are received between end crossbars 11 at the free end of the gate and secured thereto by suitable fastenings 18, similar end bars 12 being employed to embrace the rails at the hinged end of the gate and secured thereto by fastenings 14:. A pair of intermediate cross-bars 15 embrace the middle portions of the rails and are connected thereto by fastenings 16. The several fastenings 13, 11, and 16 pivotally connect the rails and the cross-bars, whereby the former may be tilted vertically upon the pivotal fastenings as centers. Any suitable or appropriate hinge-post 18 may be employed, to which the gate is connected by suitable hinges 17 to permit of the gate swinging in opposite directions from its closed position.

1n addition to the cross-bars 11, 12, and 15 the gate is also braced by two sets of diagonal braces or props, the inner set being designated by the reference-numorals 24: and 25 and embracing the rails, with their lower ends pivotally connected to the lowermost rail, as at 23, adjacent the hinged end of the gate, the upper end portions of these props or braces being connected by a transverse bar or pin 27, working in the space between the two uppermost rails. Each of the intermediate cross-bars 15 is provided in what will be termed its rear edge with notches 20, constituting a rack made up of ratchet-teeth, and the upper end of each of the braces or props 24. and 25 is beveled to successively engage these teeth, and thereby add materially to the strength and rigidity of the gate. Similar diagonal braces or props Z9 and are located between the intermediate cross-bars 15 and the end cross-bars 11, there being a pivotal connection 28 between the lower ends of these props or braces and the lowermost rail. The upper portions of the rear edges of the end bars 11 are provided with notches 19, constituting ratchet-teeth, and the upper ends of the props 29 and 30 are each beveled to successively engage the respective sets of teeth. A suitable handle *2 is carried by and projects at the outer sides of the end bars 11 for convenience in elevating the free end of the gate. During the elevation of the gate the intermediate cross-bars 15 and the end bars 11 travel upwardly across the upper free ends of the two setsof diagonal braces or props, whereby said props successively engage the teeth 20 and 19, and the gate may be adjustably supported in various vertically tilted positions by means of the props engaging the end and intermediate cross-bars.

For the purpose of supporting the gate in higher positions than can be obtained by the props engaging the end and intermediate cross-bars, the under side of the uppermost rail is provided with a series of ratchet notches or teeth .21, located between the intermediate cross-bars and the cross-bars 12 and disposed for engagement by the pin or bearing 27, which connects the upper end portions of the props 2e and 25, as indicated in Fig. 2 of the drawings. The props 2a and 25 are also connected adjacent their lower ends by means of a pin 32, working between the two lowermost rails, the lower edge of the nextto-the'bottom rail being provided with ratchet notches or teeth 22 for engagement by the pin 32 when the upper pin 27 engages the teeth 21, thereby to more rigidly sustain the gate in its tiltably-elevated position.

To provide for tiltably elevating the gate in a more convenient manner than can be accomplished by lifting upon the handle 42, an upright lever 34 is fulcrumed intermediate of its ends, as at 33, upon one of the props 29 or 30, said lever terminating at its opposite ends in suitably-formed handles. A connecting-bar 35 has its lower end pivotally con nected to the lever, as at 36, below the fulcrum of said lever, from which the bar inclines upwardly and rearwardly and is pivoted to the adjacent member of the setof props 24 and 25, as at 27. A pin 40 connects the props 29 and 30 between the two middle rails of the gate, and the lower edge of the adjacent upper rail is provided with notches 41 for engagement by the pin 40 in certain adjusted positions of the gate.

When the gate. is in its horizontal closed position, as indicated in Fig. l of the drawings, the props engage the uppermost of the teeth 19 and 20, and the entire gate-frame is rendered rigid by means of a removable pin 39 passing through the uppermost of a series of perforations 38 in the props 29 and 30 and a perforation 37 in the uppermost rail. It is proposed'to connect the pin 39 to the frame of the gate by means of a suitable flexible connectionsuch, for instance, as a chainto prevent loss of the pin. To elevate the gate, the pin 39 is removed and the free end of the gate is lifted by means of the handles 42, as hereinbefore described, or the lever 34 is swung in the direction of the arrow on Fig. 1, so as to push the connecting-bar 35 against the props 24 and 25, whereby the latter will be swung rearwardly upon their common pivotal support 23 and the pin 27 will slide rearwardly against the under side of the uppermost rail, thereby tilting the gate. During this operation the end bars 11 slide upwardly across the tops of the props 29 and 30 until the desired elevation has been obtained, with said props engaging certain of the teeth 19, whereupon the lever is released and the props 24 and 25 will gravitate into engagement with certain of the teeth 20 corresponding to the teeth 19, engaged by the props 29 and 30, whereby the gate-frame will be rendered rigid in its tilted position and at the same time capable of swinging upon its hinges. If the gate is to remain in its tilted position the pin 39 is of course passed through one of the perforations 38, which is registered with one of a series of perforations 37 in the next to the uppermost rail of the gate. A higher elevation of the gate may be obtained by a continued manipulation of the lever 34 in the direction of the arrow, so as to work the pins 27 and 32 back into certain of the teeth 21 and 22, the

movements of these pins across the lower edges of the adjacent rails tending to tilt the gate to a greater extent. When the pins 27 and 32 engage the notches 21 and 22, the free ends of the props 29 and 30 are of course disengaged from the teeth 19, and, if desired, these props may be swung back until the pin 40 engages the teeth 41, so as to afford an ad-, ditional prop for the free end portion of the gate. When the gate is to be lowered, it is slightly elevated ,by pressure of the lever 34 and lifting upon the handle 42 until the pins 27 and 32 are free from the notches 21 and 22, whereupon the gate may be readily eased down step by step without the necessity for exerting more than a slight manual force.

From the foregoing description it will be understood that the gate of the present invention is exceedingly simple and effective for the purpose designed and is capable of being propped in different elevated positions by means contained within its own structure, said means being conveniently accessible and readily controlled for raising and lowering the gate in a simple and expeditious manner. Furthermore, it is not necessary to dismantle the gate for raising and lowering the same, and the gate is capable of swinging in opposite directions in any of its tilted positions.
