B.' W. HASKETT GATE STRUCTURE I Jan. 8, 1952 2 SHEETS-SHEET 2 Filed Dec. 15, 1949 INVENTOR EURLv W HAS/(E TT F 1/LA* l ATTORNEYS Patented Jan. 8, 1952 UNITED STATES rATsNT OFFICE Claims.

This invention relates generally to an improved gate structure and has particular relation to an improved farm gate structure wherein one end of the gate is pivotally mounted to an upright support and the other end of the gate is free swinging.

One object of the invention is to provide an improved gate structure which has the singular and combined features of extreme light weight, rigidity and adjustability, simplicity of construction, a minimum of component parts and inexpensive construction.

Another object of the invention is to provide an improved farm gate structure including` a telescopic tubular cross bar sag adjuster which will permit any sagging in the gate to be automatically adjusted so that the gate may be maintained in alignment.

These and other objects of the invention will be readily understood by the reference to the following description and accompanying drawings.

The improved gate of the present invention generally comprises a pair of opposing parallel horizontal standards, a pair of parallel vertical standards carrying said horizontal standards, each pair of said vertical standards comprising two opposed members formed to nest at least partially around the periphery of said horizontal standards, and clamping means connecting said vertical standards through said horizontal stand ards at their nesting connections, to rigidly clamp said horizontal standards between said vertical standards in all positions of lift of the gate.

In one embodiment, the invention includes a gate wherein the horizontal standard comprises tubes and in another embodiment of the invention, the vertical standards each comprise an L-shaped angle iron. In a preferred embodiment of the invention, the improved gate includes a teleseoping adjustable support mounted diagonally between vertical standards, In another preferred embodiment of the invention, the improved gate includes a telescopic tubular crossbar sag adjuster comprising an outer hollow tube provided with longitudinally and serially ar ranged apertures, an inner tube slidably mounted within said outer tube, an aperture engaging pawl pivotally mounted on the telescoping end of said inner tube, and a pawl engaging tongue pivotally mounted on the telescoping end of said inner tube, said apertures being longitudinally spaced to receive said pawl and tongue so that telescoping movement of the pawl into a non-apertured portion of the outer tube causes progression of the tongue into an aperture so that said tongue prevents aperture locking engagement of said pavvl during reverse movement into an apertured portion of said outer tube. A further embodiment of the invention generally includes this combination wherein the tongue is pivotally mounted on the pawl. A further preferred embodiment generally involves a construction Wherein the tongue is spaced at a distance from the free end of the pawl substantially equal to the distance between the apertures. A further preierred embodiment generally comprises this combination wherein the telescoping tubes are each provided with an abutting spacer on their inner and outer walls respectively, the spacer on the inner tube being mounted within the telescoping portion of the tubes on the telescoping side of the Outer tube spacer.

Fig. 5 is a View similar to Fig. 4, diagrammatically illustrating the sequence of operation, and

Fig. 6 is a view similar to Figs. 4 and 5, dia grammatically illustrating the sequence of operation.

Referring to the drawings, the improved gate generally comprises a pair of opposing parallel horizontal standards iii carried at their hinged end by a pair of vertical standards indicated generally at 28 and carried at their free end by a pair of horizontal vertical standards indicated generally at 30.

Additionally, the horizontal standards lli are supported intermediate their ends by a pair of intermediate vertical standards il), which in the embodiment shown, are generally similar in structure to the end standards 2li and t. The assembled horizontal and vertical standards l, 2E and 30, comprise a rectangular frame structure in which is adjustably supported a section of fencing M, as of galvanized interlaced Wire. The fencing 4I is supported along its top and bottom edges as 'by adjustable lacing l2 and is adjustably mounted at its side edges to the vertical standards 20 and 36 respectively, by means of rod stretchers :i3 secured to the fencing 4| and adjustably secured, as by eyebolts 44 to the end standards 20 and 3&1. By virtue of this construction, the fencing may be adjusted both horizontally and vertically, by tightening or extending the lacing 132 and by tightening or extending the eyebolts 44. It Will also be noted that by virtue of the present construction, the fencing 4l may be moved both horizontally and vertically between the pair of intermediate standards 40.

Each pair of standards 2S, du and 4U comprises a pair of L-shaped angle irons 2| and 22, and a similar pair of angle irons for the intermediate standard 4D.

In a preferred embodiment of the invention, the mating pairs of standards 20, 3D and 4B are die-formed as at 23, 33 to nest around the horizontal tubes i@ to maintain stability and rigidity as in all positions of lift. The clamping means connecting the pairs of vertical standards through the horizontal standards at their nesting connections comprises a rod or bolt 2li which is secured as by screw threading through aligned holes in the vertical standards and a hole in the horizontal standards. As shown, the horizontal standards i5 comprise tubes, as of tubular steel, in which event the nesting portion 23 of each standard is arcuately formed to nest around the tubing.

The hinges for the gate comprise a hanger 25 which is fastened to the hinge standards 2Q, as by means of a bolt and nut connection to permit Vertical adjustment. The hangers 25 are adapted to pivotally carry suitable lag screws 2i adapted to be secured to a conventional gate supp-ort (not shown). The swinging end of the gate is provided with a vertically adjustable plate hasp and latch connection secured to the usual fence post (not shown), as by means of a rod lock 35. In the form shown, the vertical standards extend beyond the upper limit of the top horizontal standard 'in order to provide a support for a barbed wire strand l l which is secured to the end standards as by eyebolts i2 and slidably fastened to the intermediate standards, as at i3.

In a preferred form of the invention, a telescoping adjustable support designated generally at 55 is mounted diagonally between a pair of opposed vertical standards. In the preferred form shown, the telescoping adjustable support 55 is mounted diagonally between the top por- I tion of the hinged vertical standards 25J Yand the bottom portion of the intermediate vertical standards as by means of frame bolts 5I which provide a pivotal mounting therefor.

Referring particularly to Fig. 4, there is shown a preferred form of the telescopic tubular cross bar sag adjustor forming a bart of the present invention. The adjus tor comprises an outer support tube 52 and an inner support tube 53, said tubes being telescoped as shown. The outer support tube 52 is provided with longitudinally and serially arranged apertures 54 and the inner tube 53 is provided along its inner telescopic end portion 55 with an aperture engaging pawl 55 pivotally mounted, as at 5l, on the inner end 55 of the inner tube 53. The aperture engaging pawl 5E is provided with an aperture engaging abutment toothed portion 53 and a sliding or plane surface 59 adapted to prevent engagement with the apertures in telescoping movement.

A pawl engaging tongue 55 is pivotally mounted on the telescoping end 55 of the inner tube 53 by means of a pivot pin 5l, which in the preferred form shown, is mounted on the pawl 55. Preferably, the outer and

inner telescoping tubes

52 and 53 respectively are provided with abutting spacers 65 on their inner and outer walls respectively, the spacer 65 on the inner tube being mounted within the telescoping portion of the tube on the telescoping side of the outer tube spacer 65a. For stability, an additional spacer 65h is mounted on the inner telescoping end 55 of the inner tube 53 to provide additional rigidity during the telescoping sliding operation and during the normal position of the telescoping tubes. Preferably, the spacers 55 are provided with seepage notches '66 to permit drainage of rain water. The spacer 55 is mounted in spaced relation to the spacer 65a such that the spacers will act as a limiting abutment stop means for untelescoping movement of the tubes.

Sequence of operation of telescoping adjustable support As shown, in position number l in Fig. 5, the gate is in normal position with the spacer abutments S5 and 65a in abutting engagement and with both the pawl 56 and the disengaging tongue 60 out of engagement with the adjacent aperture 54a. In this position, the horizontal standards I are normally at right angles to the hanger frames or vertical standards 25, 3S. As will be apparent, in the normal position the Weight of the gate is carried by both the

telescoping tubes

52 and 53, said tubes being in locking engagement by means of the spacers 65, a.

As shown, in the No. 2 position, the gate is in the iirst lift position. By manually lifting the gate at its free or latching end, the center or intermediate standard lig, to which the inner telescoping tube 53 is attached, causes telescoping of the said tube into the outer tube 52, thereby driving the pawl 56 and the tongue B past position No. l, which is a pawl locking station and not a tube locking position, and further permitting telescoping movement into position No. 2, where the pawl 5t engages the aperture 541) by means of the pawl toothed portion 53, thereby supporting the frame of the gate in its iirst lift position.

Referring now to position No. 3, as shown, the gate may be locked in subsequent higher positions by lifting the free end of the gate until the pawl engages the desired aperture at the desired station for height.

It will be apparent that the gate may be lowered to normal position from any locking station by lifting the free end of the gate until the pawl 56 is past position No. 3; that is, past the last highest station, whereupon the disengaging tongue 60 drops into position No. 3, as shown, that is, into the lastl highest position.

Likewise, the gate may be lowered to any lower locking position from any locking station by lifting the free end of the gate until the tongue drops into the highest aperture (or the position No. 3 aperture), thereby lowering the gate until the tongue drops into the next lower position than that desired, and raising the gate until the pawl engages the aperture at the desired height,

It will be apparent that the tongue may be pivotally mounted directly on the pivot rod 5T on the inner end of the inner tube and that a suitable abutment member, which may be in the form of the pivot mounting Gl, may be provided as engaging means for the tongue so that the tongue may move the pawl out of the aperture engaging position upon movement of the tongue caused by sliding engagement with an aperture.

While the invention has been disclosed and described in its preferred embodiment, it will be understood that various modications may be made therein by those skilled in the art, and it is intended that all such variations as come within the spirit and scope of the appended claims shall be thereby covered.
