JOHN 'B. M-AZOCH, 'or' wnmnn, TEXAS.
Application filed March 31, 1924. Serial No. 703,205.
To all whom it may concern:
Be it known that I. JOHN B. MAzooH, a citizen of the United States, residing at lVeimar, in the county of Colorado and State of Texas, have invented certain new and useful Improvements in Adjustable Stands: and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to improvements in adjustable stands for typewriters, adding machines,invalid tables, and the like, and the principalobject is to provide an exceptionally simple and inexpensive stand structure which may be easily assembled and may be quickly'adjusted, with ease, to any desired height.
With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.
Figure 1 is a side elevation partly in section.
Figure 2 is a central vertical sectional View, parts also of the legs being broken away and in section.
Figures 3 and 4 are horizontal sectional views as indicated by lines 3-3 and 44 of Figs. 1 and 2, respectively.
In the drawing above brieflv described. the numerals 1 and 2 designate u er and lower leg sections telescopically engaged with each other, all of said sections being preferably formed of piping. The upper sections 1 may well consist of upper and lower halves 3 and 4 connected by T-couplings 5 whose lateral branches 6 extend inwardly. I have shown short radial arms, preferably formed of piping, threaded into the branches 6, said arms being designated by the numerals 7. At their inner ends, these arms are threaded into or otherwise secured to a central block 8 which may well be of the cross shape shown in Fig. 4:.
At suitable points, preferabl near their lower ends, the lower leg sections 2 are formed with openings 9 in their inner sides, and from these openings. a plurality of brace rods 10 converge upwardly and inwardly, the lower ends of these rods being bent outwardly at 11 through the openings 9 and then bent downwardly at 12 within the leg sections 2 and in contact with the inner sur faces of the latter. The upper ends of the rods 10 are secured to a lower, center block I g 1,527,895 v PATENT oFFlcE.
13, for instance by threading them at 14: in
suitable openings formed vertically through said block.
A central vertical screw 15 passes through central openings 16 in the upper and lower blocks 8 and 13 and has opposed threaded engagement with said blocks as shown, this screw being provided with a readily accessible hand wheel 17 by means of which it may be quickly and easily rotated toraise or lower the upper block 8 and the leg sections 1 connected therewith. The table top or other member to besupported. which member is designated at 18 in the drawing. may be secured to the upper ends of these leg sections 1 by any suitable means. such as the flanged sockets 19.
The brace rodslO are given the formation shown before they are engaged with the block 13 and the leg sections 2. Then, after latter are angled to permit the lower ends of the brace rods to be passed through the openings 9. Then, theleg sections 2 are righted and the upper sections 1, are telescoped therewith, the screw 15 being in the meantime, engaged with the upper and lower blocks 8 and 13. By providing a construc tion. assembled in this manner. it'may be easily and inexpensively manufactured but when assembled will be rigid to the necessary degree. At any time. the height of the stand may be varied, simply by turning the hand-wheel 17. I
As excellent results are obtainable from the details disclosed, they are preferably followed, but within the scope of the invention as claimed, numerous minor changes may be made. 7
1. A vertically adjustable stand comprising upper and lower leg sections telescoped with each other, upper and lower vertically alined center blocks between said upper and lower leg sections respectivel radial arms extending between said upper block and said upper leg sections and rigidly secured to both, upwardly and inwardly converging braces extending from the lower leg sections to the lower block and connected with both, and a central vertical screw operatively associated with both of said blocks for raising and lowering the upper block and the upper leg sections,
2 A structure as specified in claim 1; the
lower leg sections being tubular and having 5 openings in their inner; sides, the lower ends;
of said braces being formed with horizontal portions passing outwardly through said openings and with vertically projecting portions at the ends of said horizontal portions and received in said tubular lower sections. 10
In testimony whereof I have hereunto atfixed my signature.
