ttf-Claims. 1.

This invention relates to improvementsin gates for enclosures,v such as farm gates, andmorepanticularly to extensible `gates which may beadjusted in length.

One of the objects of the invention is to provide a gate withteleseopic eXtensible-sections, the eXtensible sections all telescoping intovthe first, or hinged-section, to minimize the gate size to facilitate shipping thereof.

Another vobject is to providea gate of the fore; going type -in which the-length of the gate may be readily adjusted to t between vgate ,posts of an enclosure.

Another object isto providea gate which is extremely strong in proportion to its weight.

Another object is to provide a gate of i welded tube construction'which has a Vminimum number of parts.

A further Objectis toprovide a gate `whiclrmay be economically manufactured Still further objects, advantages,` and salient features will become'more apparent froma consideration of the description to follow, `the appended claims, and the accompanying drawing, in which: I

Figure 2 is a side elevation Yof the gate in substantially contraetedpositionas it would Vappear whilefbeing shippedfor instorage;

Figure '7 is an enlarged section taken on line 1 1, Figure 1;

Figure 3 is an enlarged section taken on line 8 8, Figure. 2; `and Figure 9 is an enlarged section taken on line 9 9, Figure 2.

Referring Vin detail to the drawing, and, particularly Figure 1, the gate comprises in general, a plurality' of sections I0, Iv I, and I2, sectionv I0 being pivotally supported on a post I3, the lower end of whichA is embedded in concrete.

Section I comprises a vertical metal tube I4 which telescopes over post I3, as best shown in Figures and 6, post I3 being provided with a collar I5, welded to the post, which provides a thrust bearing for tube I4. The upper end of post I3is threaded and receives a pipe cap I6 which closes the-upper end ofthe post andfalso serves as lan abutment for the Aupper end of tube I4. Fittings It-'I arerprovidedon the tube, these being of any well knownftype, for Vreceiving the end of a-grease gun `so thatfgrease may be forced between -post I3 fand tube I4. A plurality-'of horizontal tubes 18', i9, 20, and 2I are contoured at their left ends (Figure 1) tot tube I4, as' shown at 22-1in Figure f7, andareweldedthereto, with a weld which extends around the curved ends of the horizontal tubes, lwhere they join with tube I. Spacer tubesf23; 24,' and25 are similarly contoured at their-upper and lower ends and are-welded, respectively, to tubes I8 and I-S I9 andIEll, and 20 `and-ZI. Gusset plates 2ia're welded to the various- `horizontaltubes and the vertical tube, in the'arrangement shown in Figure 1. Alternatively, diagonal braces extending between opposite cornersof `the rectangles-formed by the horizontal and vertical tubes may be employed. Section. I I comprises horizontal tubes 21;'28, Z9 and 3i) which are of "such size that they tele'- scope, respectively` within tubes I8, I9, `2U and ZI vof section I0; Spacertubesl, 32qand '33 arel contoured at their `upper and vlower ends and welded tothe 'fhorizontaltubes inthe same mau'- ner as the vertical spacer tubes of section I0. Section I2V comprises horizontal tubes '34, v35, 3S and `3l which are of `such size that they telescope, respectively, within tubes 21, "28, A29'and 30; The right ends of these tubes are contoured'and welded to a single vertical tube 38 in the saine manner explained in connection with tubes t3 to Z'I wheretheyjointubel. f A plurality of apertures `39 are provided in each ofthe horizontal ltubes through which bolts' 4B" passA toV thus secure the sections together in a desired position. AIn event' the opening between fence posts is such that :the gatedoes not iitga's desired, with the apertures '39; as provided, cross holes such as v39 are merely drilled through the horizontal tubes for the reception of bolts 49'.'

The gate may be varied in size, as desired, and the` number of sections increased or decreased.. A gate A'which vhas been found very versatile is about five feet high and' each section aboutsix feet long,tl1etubing in the lsection IIlJbeing aboutv one and one' half inches in diameter andabout fourteen gage in thickness. The tubing in section I I is, of course, slightly smaller in diameter, and the tubing in section I2 slightly smaller in diameter than that of section II. This provides a gate which may be extended to about fifteen and one half feet. If greater length is desired more sections may be added, or alternatively, two gates may be provided, one hinged adjacent each fence post 4l, 42. Thus, an opening of about thirty one feet between fence posts may be accommodated with two gates of the dimensions above given.

As shown in Figure 2, the gate may be telescoped to the length of section' I0 plus the diameter of the vertical spacer bars Eon section I l and spacer bar 38 on section I2, that is, the dimensions of the entire gate when contracted is only slightly longer than section I0. This facilitates shipping of the gate and also reduces shipping and storage costs since the bulkiness of goods is a factor of such costs. A1so,a minimum numi.

ber of parts are employed in the gate lwhich reduces its weight and cost of manufacture.

While the various joints have been described as weldedf this term is to be construed in the claims in a generic sense and to include joining 0f the metal tubes by a dissimilar metal, for example, brazing when steel tubes are employed. Other modifications will occur to those skilled in the art and hence the specific structure illustrated is to be regarded as exemplary only and the scope of the invention is to be measured by the appended claims construed in the light of the spirit of the entire disclosure.
