EXTENS IBLE ROD Filed Sept. 17; 1926 ATTORNEYS Patented Mar. 19, 1929.

WILLIAM L. MITCHELL, F BROOKLYN, NEW YOBK/ ASSIGNOR TO BATTLE GREEK SURGICAL SUPPLY & SUPPORTER CORPORATION, OF

CORPORATION or MICHIGAN.

EXTENSIBLE ROD.

Application filed September 17, 1926. Serial No. 136,049.

This invention relates to improvements in extensible rods, and has for one of its objects to provide a simple and practical constructionwherein a plurality of sections are telescopically arranged and joinedto each other in such manner that the same may be extended to secure a maximum length of rod. 7

Another object is to limit the movements of the sections of the rod to extended positions by providing an intermediate section with a tube-like member having flanges ateach end which contact the abutments carried by the adjacent sections so as to prevent further outward movement of the sections relative to each other after the same have been fully extended.

The above and other objects will appear more clearly from the following detail description, when taken in connection with the accompanying drawing, which illustrates a preferred embodiment of the inventive idea.

In the drawing- Figure 1 is a longitudinal section through a rod in extended position and constructed in accordance with the invention;

Figure 2 is a section on the line 22 of Figure 1; and I Figure 8 is a section on the line 3-3 of Figure 1.

Referring more particularly to the accompanymg drawing, the numerals 4, and 6 indicate an intermediate'and two end sections comprising the rod, the section 4; being telescoped within the section 5 while the section 6 'is similarlyarranged within the section 4.

The section 4 is provided with a closed end/7 having an opening 8 which is surrounded by one endof a tubular member .9 arranged centrally within the section and extending longitudinally'thereof for practically its entire length. The disposition of the member 9 with respect to the opening 8 forms on the closed end 7 an annular flange 10 which surrounds said opening. The opposite end of the member 9 is pro vided with an annular outturned flange 11 for a purpose which will presently appear.

The section 5 is provided with the closed end 12 in which is centrally mounted one BATTLE CREEK, MICHIGAN, A

end of a rod 13 extending longitudinally of the section and having its outer end project ing through the opening 8 in the section 4.

Said outer end of the. rod is provided with a disk-like head 1% which forms an abutment movable in the member 9 and adapted to contact the flange 10in order to limit the movement of the sections 4 and 5 to their extended positions and thereby prevent complete detachment of said sections.

The section 6, which is movable within the section 4,.surrounds the tubular member 9 and is provided at its inner end with an inturned flange which is adapted to contact the flange 11 at the outer end-of the member 9 when the section 6 is at the. i

limit of its extended position.

- Thus the invention provides an extensible rod which may be used for various purposes and in which the sections thereof may be extended to, secure a maximum length for the rod and which, when in extended position, will be properly braced by the adjacent section and prevented from becoming accidentally detached therefrom.

What is claimed is: 1. In an extensible rod, an' intermediate section having a tubular member forming an integral part thereof and extending from one end of the section to a point adjacent. its opposite end in spaced relation to the wall of said section, a second section into which the first named section telescopes, a rod in said second section projecting through the first named end 01 said intermediate section and into said tubular memher, said rod having means engageable with, said first named end to limit out-ward movement of said intermediate section relative to said second section, and a third section movement of said third section relative to the intermediate section.

2..In an extensible rod, a plurality of tubular telescoping sections one of which is provided at one end with an inturned flange having an opening, sa1d SeCtlOIl also opening and extending from said end of havlng a tubular member surrounding said 7 i the section toward the opposite end in sections and projecting through said opening and having a head movable in said tubu lar member for contactwith said inturned flange to limit the movements of said sections to extended position, and a'third section Within the first named section and havlng an abutment at lts lnn'er end cooperating With the abutment on said opposite end of the tubular member to limit outward movement of said third section.

In testimony whereof I have afiixed my 15 signature. 7
