ne it known l that Lisancnnsnnn eee HORN, a eitizenofthe United States,V .residing atPhilipsburgQ in'th'e Vcounty of vCentre and State o f Pennsylvania ,have invented. a 'eertain new anduseful 'PianoStooh'of which the following isa 'speci`oaton,' reference lvjein'g'-V had therein to the aoco mpanyinggdravriiigsnV `This invention relates tolpiano-stools, andj is kin the nature of an' improvement upon Vthe construction disclosed inf Letters' Patent i granted to mek April 13, 1897, Nero-80,665.

The object' of the present invention is to simplify, improve, and cheapeu the cost of manufacture of the 'stool described andillnstrated in my said formerv patent above re' ferred to and to `render the same ass-:farl as' possiblevself-adj usting, thep'ar'ts bei-ng 'so arranged that the top or seat proper maybe quickly raised or loweredand securely held at the desired point of adjustment without the necessity of thepperato'r getting oiithei stool. Y'

. 1t is within the scope of this invention to construct the stool either as a single or a double stool forindividual playing or for duety The construction kmay of coursevv purposes. be varied to adapt the stool to pianos or organs, Whether'fory -usein the horneor in churches or other public places.

The invention consists 1n an improved piano-stool embodying certain novel features and details of construction and ar'rangementy ofp'arts, as hereinafter fully described, illustratedin the dra'u'rin'g's,` and incorporated inthe claims hereto appended.

In the accompanying drawi a side elevation of astool constructed in accordance with the present invention.' Fig.' 2

is a vertical central longitudinal sectionv through the same.

Fig. 3 is asectionon the line ,do an, Fig. 1, looking` in the direction of thearrotvsY 5 'Referring to the drawings, the stool isseen to comprise a base or stand composed of aseries of upwardly-converging legs 1, connected at their upper ends to thetop`2. To the oeuf ter of the top 2 is secureda depending post or upright 8, which isconne'cte'dat oinear its lower end to the legs 1 by means of radiating braces 4:. The construction and arrangement of the parts above referred tois not essential [In carrying out v Y v 'post or upright 3 is made hollow, as indicated4 f ngs,' Figure 1 is l to thelprinciple of lthe invention hereinafter disclosed and may be varied in design or otherwise.'

the presentinvention the atljforv 'the vgreater portion of itslength, and Withingsaid post or upright is secured a tubularkme'ptal socket-piece 6, provided in one side.

with a longitudinal seriesof recesses or openings ''for a purpose hereinafter explained. Fitting t'elescopically andsnngly. .within the socket 6 is a tubularstem 8, connected at its Q by means of acollar,

upper endto the seat ferrule, or sleeve .10. Thestem ,S is adaptedj to slidel smoothly and evenly into the socketpiecef, and relative rotative movem ent of the parts 6 and S is prevented by means of a set- Vscrewlla which passes through the projectingr upper end of the tube (i, with its inner end resting in yalongitudinal groove or keyway 12 i'u the stem 8. B y loosening the screw 11 1 the stem S of the seat may. be adj usted up and down Within the Apart G` and clauipedvand securely held at any desired point by means of saidscrew. Within the tube G is-placed a coiled spring 13,the upper end of whichbears against the lower end ot' the stem 8 and serves tonormally thrust ysaid stem and the seat Ot' Y the-'stool upward.

'14 designates an elbow-lever constructed,

preferably, oi a metallic rod and having onearm'lrextending downward through the holloivstem S, Where its lower extremity is bent and extended laterally to form a catch 16, 4adapted to engage in any one of theopenings or recesses 7 for holding the seat atlthe desired height and preventing fthefspring 13 from thrusting the seat upward at an inopportune moment. The remaining arm 14; of the lever y17 ertends outward radially from the stem S and beneath the seat 9 to a point immedi ateiy adjacent to the outer edge or periphery ofthe seat, where it is formed into anr eye 18, which constitutes a finger grip or handle-by means of Whichjthe lever may be vibrated. The seat 9 is provided with a radial` recess or depression 19 kin its lowerjside to admit of the necessary movement ofthe arml'ofv the dat spring 20, the inner end of which is secured xedly to the seat andthe outer end deflected downward to bear against the uprco 'lever 14, and Within saidrecess yis placed a per sido of the lever lll near its outer end. Near the outer end of the lever and secured to the under side of the scat is a lever-guide 2l in the form ol a staple, the lever working up and down between the parallel portions of said guide and being limited in its downward movement by the curved lower end or cross portion of said guide.

By means of the construction above described it will be seen that the stool is selfadjusting to the extent that when the occupant of the stool operates the elbow-lever and disengages the catch 16 from the open- .ings or recesses 7 in the tube G the spring 13 will act on the lower end ot the hollow stem S to quickly elevate the seat. Upon the operator releasing the lever the spring which actuates the lever will cause thelower end or catch portion lo thereof to automatically move into engagement with the nearest opening or recess in the tube (i, thereby sustaining the seat at the desired elevation. In order to secure the seat against any accidental movement up or downl the set-screwll may be tightened.

lt will of course be understood that the principle of the invention hereinabove set forth maybe applied either to single or double stools; also, that any desired ornamentation may be given to the stool, and the top or seat proper may be either plain, turned, or upholstered, according to the desire of the n'ianufacturer. These and other changes in the form, proportion, and minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention.

Having thus described the invention, whatV is claimed as new, and desired to be secured by Letters Patent, is

l. The combination with a base orstand and a seat movable up or down relative thereto, ot' telescoping tubes, one of which is secured to the base and provided with a series of perforations arranged yin a vertical row and the other vhaving a longitudinal groove and being secured to the seat through an annular collar or sleeve at its upper end, an elbow-le ver passing above and through .said sleeve and down through the tubes and havinga catch on its lower end passing through a perforation in the inner tube and adapted toengage any one of the perforations in the outer tube, a spring secured to the seat and vpressing down upon the horizontal upper arm of the elbow-lever, and adjustable means connected with the base-tube and engaging the groove in the seat-tube for preventing relative rotation of the tubes and of the seat and base connected therewith, substantially as described.

2. The combination with a base orstand and a seat movable up or down relative thereto, of telescoping tubes, one secured to the base and the other secured to the seat through an annular flange or collar and having a longitudinal groove, an elbow-lever passing through said collar and thetube connected therewith and provided at its lower end with a catch passing through an opening in the seat-tube and adapted to enter openings in the basetube, its upper outwardly-projecting arm eX- tending over the collarfand through a groove in the lower face of the seat, a spring secured in. sait groove and acting upon said upper lever-arm forholding the catch normally in engagement with the base-tube, and means substantially as described for preventing relative rotation of the tubes or seat and base.

The combination withabase orstand,and a seat movable up or down relative thereto, of telescoping tubes, one of which is secured to the base andthe other secured to the seat through an annularilange or collar', an elbow lever passing through said collar and the tube connected therewith and provided at its lower end with a catch passing through anopening in the inner tubeand adapted toengage openings in the base-tube, its upper outwardlyprojecting and vertically-movable arm extending over the collar and through agroove in the lower face of the seat, a spring secured in said groove and acting upon said upper lever-arm for holding the catch normally in engagement with the base-tube, a- U-shaped guide for said vertically-movable lever-arm attached to and pendent from v'the seat, and means for preventing relative rotation of theV tubes, substantially as described.

et. The combination withabase or stand and a seat movable up or down relative to said base, of telescoping tubes, one secured to the base and the other longitudinally grooved and secured to the seat through an annular iange orcollar, an elbow-lever passing through said collar and the tube connected therewith and provided at its lower end with a catch adapted to engage openings in the base-tube, its upper outwardly-projecting and verticallymovable arm extending over the collar and through the groove in the lower face of the seat, a spring secured in said groove and acting upon said upper lever-arm for holding the catch normally in engagement with the base-tube, a U-shaped guide for said vertically-movable lever-arm attached to and pendent from the seat, a spring acting on the lower end of the seat-tu be for automatically raising said tube and the seat when said tube is released frorn the base-tube, and a set-screw in the base-tube entering the groove in the seattube for preventing relative rotation of said tubes and of the seat and base or stand connected therewith, substantially as described.
