TELESGOPIC STAND.
Specification of Letters Patent.
Application filed May 23, 1912. Serial No. 699,264.
To all whom it may concern: I
Be it lmown that I, JOHANNES FRANKIE, a subject of the I Germany Emperor, and resident of) Dresden, Germany, have. invented certain new and useful Improvements in Telescopic Stands, of which the following is a specification.
This invention relates to an improved telescopic stand, for any appropriate purposes, which can be automatically arrested in any Theimproved stand is represented on the accompanying drawing. I
Figure 1 is a central section through same, Fig. 2 a cross section, on the line AB of Fig. 1, and Fig. 3 across section on the line GD of Fig. 1, while Fig. 4 shows the upper part of same in a central section, with a modification.
The stand comprises an outer tube 1, which is preferably closed at the bottom and at its top provided with a cap 2. Through said cap a pipe 3 projects centrally into said tube, which at its top carries also a cap 4:. Through the latter, a rod 5 projects centrally into said pipe, the top end of said rod being provided with a button 6. The latter lies within a central depression in the table an arranged on the top end of pipe 3. The lower end of said rod carries a transverse member 7 which projects transversely through two elongated slots 8 in the lower end of said pipe. Thepipe 3 terminates at the bottom in a flange 9, which again carries on its underside a central inverted cone 10. Said flange is inclosed by a movable shell 11 with closed bottom and open top, on which end its edge 12 is somewhat bent inward. Between said edge 12 and the flange 9 intervenes a spiral spring 13 which presses the shell always against the transverse memher 7, while between said flange and the bottom of shell 11 a plurality of balls 14 are located, which project through holes 15 in the walls of the shell so as to directly face the inner walls of tube 1.
The operation is as follows :Upon the stand being put into the desired position, the load resting on top of pipe'3 depresses the inverted cone 10, so that the balls 14 are compelled to travel up the inclined walls of same, whereby they are. firmly clamped between the latter and the inner walls of tube 1. To effect disengagement of the balls, it is simply necessary to exert a downwith the balls in its holes 15 is moved down and the balls are no longer clamped between cone and tube, so that pipe 3 can be freely moved up or down in tube 1.
Fig. 4 shows a modification of the operat- I A, telescopic stand, comprising in combi nation, a tube, an upper cap on said tube,
Patented Dec. 24, 1912.
a centrally and movably arranged supporting pipe in said tube projecting from said cap and provided with slots inits lower end, a centrally guided rod in said pipe, a transverse member on the bottom of said rod to project through said slots, a flange on the bottom of said pipe, an inverted central cone bent edges and holes in its walls below said flange, a spiral spring to intervene between the latter and said flange and adapted to press said shell toward said transverse Inem- I ber, and a plurality of balls movably arranged in said shell to project through the I holes therein and to facesaid cone on one ing witnesses.
