SCHOOL FURNITURE.
Specification of Letters Patent.
Application filed October 19,1916. ammo. 126,511.
' SCHMITI, J r., and RICHARD D. SPAIN, citizens of the United States, residing in Passaic, in the county of Passaic and State of New Jersey, and residing in Montclair, in the county of Essex and State of New Jersey, respectively, have invented certain new and useful Improvements in School Furniture, of which the following is a specification.
The present invention relates to certain new and useful improvements in the construction of supporting pedestals or standards for articles of school furniture and the like, the object of the invention being to provide a standard which embodies novel features of construction whereby it is' normall held rigidly in a fixed position upon the oor, but can be easily and quickl detaehed from the floor, leaving a per ectly smooth floor surface which can be used for school exercises, dancing, or the like.
Further objects of the invention are to provide a supporting pedestal or standard of this character which is comparatively simple and inexpensive in its construction, which can be readily placedin position or removed therefrom, which provides for ver- -tical adjustment of the supporting member,
and which can not be easily broken by the rough handling to which such devices are ordlnaril subjected when in use.
With t ese and other objects in view, the
' invention consists incertain novel combinations and arrangements of the parts as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.
For a full understanding of the invention, reference is to be had to the following description and accompanying drawing, in which I Figure 1 is a perspective view of a school seat or stool constructed in accordance with the invention.
Fig. 2 is an enlarged vertical sectional view through the same, on the line 2-2 of Fig. 3 is a perspective view of a school desk or table em y g the invention,
Fig. 4 is a detail view of the clamping nut and spring washer which is employed for lock ng the parts in an adjusted position.
Corresponding and like parts are referred to 1n the followin description and indicated 1n all the views 0 the drawings by the same reference characters.
Referring to the drawings, which illus-.

trate one embodiment of the invention, the
one of the arms of the bifurcation being provided upon the inner face thereof with a series of transverse teeth 19. A pinion 20 is rigidly applied to the transverse shaft 18 in such a manner that the teeth thereof mesh with the rack teeth 19 on one side of the bifurcation, and clear the opposite side of the bifurcation. One end of the transverse shaft 18 is journaled within a bearing plate 21 embedded in the standard 5, and terminates in a polygonal head 22, while the opposite end thereof terminates in a threaded stem 23. A nut 24 is fitted upon the threaded stem 23 and a washer member 25 is arranged under the nut, said washer member being formed with a series of radially extending and inwardly deflected spring arms 25 adapted to frict-ionally engage the side of the standard 5. When the nut 24: is loosened, the shaft 18 and pinion 20 can be readily r0- tated by applyin awrenchtothe polygonal end 22 of the sha t, and the/stem 17 thereby moved up or down to set the seat 15 or other supported member at any desired elevation. The parts are then looked in position by tightening the nut 24.
Fig. 3 illustrates a slight modification which is especially adapted for the support of desks and tables where two spaced standards are preferably employed. These standards 5 are shown as rectangular in formation, and the stems 17 upon which the desk or table 15 is supported also have a rectangular formation. A single transverse shaft 18 connects the standards 5 and is journaled therein, said shaft carrying the pinions 20 which mesh with the racks 19 of the respective bifurcated stems 17. The middle portion of the transverse shaft 18 has a polygonal formation, as indicated at 22, so that by rotating the shaft the two stems 17 can be simultaneously raised and lowered. The sides of the tubular standards are formed with the transverse slots 6 through which wrenches can be inserted for loosening the nuts of the clamping bolts when it is desired to remove the standards from the base-plates, exactly as in the previous instance. When the standards are clamped in position, rigid supports are provided for the seats, tables, or other articles of furniture, although when it is desired the standards can be detached from the base plates, leaving a perfectly smooth floor surface which'is free from rojections and can be used for school exercises, assemblies, dancing or the like.
Having thus described the invention, what we claim as new and desire to secure by Letters Patent, is
1. The combination with a floor plate provided with an upwardly projecting headed stud, of a tubular standard adapted to be fitted removably upon the floor plate, the base of the tubular standard receiving the headed stud of the floor plate, a link loosely suspended within the tubularstandard and provided at its lower end with a laterally swinging claw for detachably engaging the shank of the headed stud, and means for tightening the link to draw the standard firmly into position.
2. The icomloination with a floor plate provided with a headed stud projecting upwardly therefrom, a tubular standard adapted to be detachably secured to the floor plate, the base of the tubular standard receiving the headed stud, a cross bar in the tubular standard, a loosely pendent link Within the tubular standard, the lower end of the link link to the cross bar, said clamping bolt enabling the bolt to be tightened to draw the standard firmly into position.
3. The combination with a floor plate provided with an upwardly projecting headed stud, of a tubular standard having an opening in one side thereof and adapted to be secured to the floor plate, the base of the tubular standard receiving the headed stud, a cross bar arranged within the tubular standard above the side opening thereof, a clamping bolt extending downwardlywithin the tubular standard from the cross bar, a link member loosely pendent from the clamping bolt and provided at its lower end with a laterally projecting claw adapted to be swung laterally into and out of engagement with the shank of the headed stud, and a nut fitted upon the clamping bolt and adapted to be engaged by a tool inserted through the before mentioned side opening of the standard, said nut enabling the link to be tighta cross bar extendin across the tubular standard above the si e opening thereof, an upright clamping bolt extending downwardly' from the cross bar, a link member loosely pendent from the clampin bolt, and
constructed at its lower end to etachably engage the stud of the floor late, and a nut fitted upon the clamping be t and arranged to be engaged by a tool inserted through the before mentioned side opening of the stand- 10 HENRY A. HUBSCHMITT, JR. RICHARD D. SPAIN.
