SAME PLACE.

ADJUSTABLE AND SEPARABLE FURNITURE.

SPECIFICATION forming part of Letters Patent No. 861,992, dated .April 26,1887.

Application filed November 24, 1886. Serial No. 219,807. (No model.)

To all whom it may concern:

Be it known that I, ANDREW J. GRoN, of Piqua, Miami county, Ohio, have invented a new and useful Improvement in Adjustable and Separable Furniture, of which the fol lowing is a specification.

My invention relates to an improved construction of those articles of furniture whose upper portion is capable of vertical adjustment upon or of separation from the supporting part or parts thereof. \Vhether designed for ready attachment and separation merely, or it be desired to utilize the construction for the additional advantage of vertical adjust ment, my device comprises the following essential parts: The lower member has an upwardly-projecting cylindrical wooden shaft or post into whose top and coincident with its axis there is permanently secured the gimletformed lower end wood-screw portion of a steel or iron rod. The upper member has a vertical excavation whose lower part fits snugly around the said post, and whose upper part receives a tightly-wedged iron nut which receives the correspondingly-threaded upper end of the aforesaid rod. A small passage at the middle of the excavation just suflices to admit the said rod.

Of numerous articles of furniture to which my invention is applicable two are herein represented by axial sections, in which like figures refer to like parts.

Figure 1 shows my invention adapted to an article of furniture having asingle central support-such as a pianostool or an officestool, a childs chair, a flower-stand, a chesstable, or the like. Fig. 2 shows myinvention adapted to an article of manufacture,- such as the leg of a table or desk.

Projecting vertically from the center of a base, 1, is a cylindrical post, shaft, or tenon, 2, of wood. Permanently screwed into the top, and coincident with the axis of, said post or shaft, is the gimlet-formed lower end or wood-screw portion 3 of a steel or iron rod, 4, whose upper end, 5, is suitably threaded for screwing into an iron nut, 6, that constitutes part of the upper member of the article of furniture. The rod 4 has an annular shoulder, 4:, which seats on the post 2, as shown in Fig. l.

The upper member above referred to comprises a wooden stem, 7, through which ex tends a cylindrical and coaxial excavation whose portions 8 and 9 at its lower and upper extremities, respectively, communicate with each other by a contracted passage, 10, whose diameter just suffices to admit the rod 4.. The lower portion, 8, of said excavation has depth and diameter as toenable it to fit snugly ho over the post 2 aforesaid, while the diameter of the portion 9 is such as to permit the nut 6 to be tightly wedged within it in the manner represented.

The two metallic portions 3 and 6 having been permanently fixed in the respective lower and upper members in the manner represented, and a seat, slab, or other desired top piece,

11, having been suitably attached, the article of furniture may be easily put in condition for use by the simple act of inserting the upper extremity of the lower member within the excavation 8 9 10 and revolving it to the right until the screw-threaded upper end, 5, of the rod 4 becomes engaged in the not 6.

The description given with reference to Fig. 1 is alike applicable to Fig. 2, except that if the latter figure be taken to represent an articleoffurniture for which no adjustment is desired the described parts may be much shorter, as shown in said figure.

I am aware that all the main features of my invention, separately considered, are old.

I do not therefore claim such features,broadly, but only when combined with certain details of construction.

I claim as a new and useful article of manufacture- The combination of the lower member formed with a cylindrical post, 2, the upper member formed. with an upper excavation, 9,

a lower excavation, S, in which the post travels, and a contracted passage, 10, a nut, 6, wedged in the upper excavation at the base thereof, and the rod 4, formed with a wood- 5 screw portion, 3, at its lower end, fixed in the post and adjustable therewith, an annular shoulder, 41., seated on the post, a middle portion playing in the contracted passage, and a screw portion, 5, at its upper end working in the upper excavation through the nut, sub stantially as shown and described.

In testimony of which invention I hereunto set my hand.
