TELESCOPIC POLE.

T '0 all whom it may concern Be it known that 1, 12mm 0. looxn, a citizen of' the United States, residing at Lake City, in the county of Wabash-a and State of Minnesota, have invented certain new and useful improvements in Telescopic Poles, of which the following is a specification, reference being had therein to the accompanying drawing.

,This invention rovides poles that are formed of telescopic sections, whereby the sections may be nested one within another and made into compact units. The poles particularly. are adapted for use as tentsupports, they may be stowed easily in a canoe, automobile, or other vehicle, and the invention contemplates both upright and ridge poles of this kind.

The arrangement of each pole is such that it may be easily; and quickly extended and telescoped means are provided for reliably maintaining, the poles extended, and the arrangement is such that the ridge-pole may be connected to the upright poles.

When read in connection with the description herein, the details of construction and arrangement of parts contemplated by the invention will be apparent from the accompanying drawing, forming part hereof, wherein embodiments of the invention are disclosed, for purposes of illustration.

While the embodiments herein explained now are considered to be preferable ones, it is to be understood that'alterations can be made in them within the limits of the claims without departing from the nature and spirit of the invention.

Like reference-characters refer to corresponding parts in the views of the draw ing', of which Figure 1 is a view of an upright pole extended; Fig. 2 is a View, partly in section,

of an upright pole telescoped; Fig. 3 is a View of a ridge-pole extended; Fig. 4.- is a view, partly in section, of a ridge-pole telescoped; Fig. 5 is an enlarged sectional View of a joint; Fig. 6 is a transverse sectional view, on the line 66, Fig. 2; and Fig. 7 is a top view of the cap and base plate at the bottom of the upright pole.

The poles are made preferably of metal tubi g of difierent sizes in the various sectio s, whereby the sections may telescope one with another. Y

vent the pole from settling into the ground when in usea The upright pole includes any desired number of upper sections 11, each sufliciently small to slide within the next lower section. The upper end of each section is exteriorly screw threaded, as shown at 1'2, and each of these threaded portions, except that of the upper section, is engaged by an interiorly threaded end of a collar 13-. The bore of each collar, except in its threaded portion, is of less diameter than the section to which it is secured, whereby there is an abutment 1% at the end of the threaded portion of the bore. The section telescoping into another section to which a coll aris attached is of a size to contact snugly with the smaller portion of the bore of the collar. Each section, except the lower one, has on its lower end an exterior annular flange or shoulder 1:), which snugly contacts with the inner surface of the section in which it is disposed and which is arranged to seat against the abutment 1 1 of itscontaining section when the sections are extended and thereby to prevent separation of thesections. Each of the sections provided with a flange 15 has on its exterior a screw-threaded portion 16 so spaced from'the flange that it will have position just outside of the outer end of the collar 13 when the sections are extended. On each of the sections formed with a threaded portion 16 there is a nut 17 arranged to screw on those portions and against the end of the collar of'the containing section, whereby flange 15 can be drawn tightly against the abutment 14; and the sections held firmly extended. The nut on one section is sutliciently large to prevent the nut on the next larger section from passing over it, whereby disarrangement of the nuts on the pole is obviated. A cap 18 is secured on the upper or outer end of the upper sec tion, and this cap is sufficiently large to prevent the section containing the upper section and the nut thereon from passing over it. The cap 18 has a pin 20 or the like exextended condition. The flanges and abutments serve to prevent the sections from becoming entirely separated when they are beingl drawn outwardly of one another. If it is esired entirely to disassemble the parts of the pole, that may be accomplished by removing the caps and collars described.

The ridge-pole may have any desired number of sections, and it is constructed in substantially the same manner as the upright pole, except that the middle section 21 is the largest, it is about twice the length of the outer-sections 22, it is arranged to have outer sections telescope therein from each end, and it has at each end a collar 13 for the same purpose as'the collars of the upright 'pole. Midway between its ends, the middle sect-ion has a stop 23' to prevent the outer sections-from passing too far into it from one end and pushing sections out from the other end. The outer sections are formed, as are the upper. sections of the upright pole, with collars 13, abutments 14,- fianges l5, threaded portions 16, and nuts 17, and the end sections have at their outer ends the caps 18. The middle section of the ridgepole being the largest of the sections thereof, the pole when extended is strongest in the middle portion Where the greatest strain is imposed when in use. A hole 24 is provided near the outer end of each outer section of the ridge-pole to receive the pin on the upper end of an upright pole and thereby to form a reliable connection therewith when two upright poles are used, one at each end of the ridge-pole, to support the latter. In case it is desired to use only one uprightpole, and that at the center of the Copies of this patent may be obtained for Letters Patent, is

1. A pole comprising a larger section, a smaller section telescopic in the larger, an abutment in the larger section near its end, a shoulder on the smaller section capable of contact with said abutment when the smaller section is extended, screw-threads on the smaller section having position exterior of a an end of the larger section when thesections are extended, and a nut coiiperable with said threads and the end of the larger section to cause said shoulder and abutment to contact and to maintain the sections in.

extended relation.

2. A pole comprising'tubular'sections of different sizes one telescopic within the other, a collar screwed onto the end of the larger section through which the smaller section slides and on said collar an interior abutment, a shoulder near the inner end of the inner section capable of contact with said abutment when the sections are ex tended and screw-threads onthe smaller section having position exterior of said collar when the sections are extended, and a nut cooperable with said screw-threads and the outer end of said collar to cause said shoulder and abutment to contact and to. maintain the sections in extended relation.

In testimony whereof I aiiix my signature in presence of two witnesses.
