This invention relateslto improvements in stools or similar obj ects of furniture, and has for its primary object to providea stool of this character which is adapted for use upon streetcars .or other moving vehicles. The devicemay also be used as ofiice or laboratory stools and may also find use in various other fields where a stool of great flexibility is re quired and which will adapt itselfto the ever-changing position of the occupant. This object isaccomplished by theprovision of an improved spring structure which serves to absorb the shocks imparted thereto and to prevent jolts and jars from interfering with the comfort of the occupant, thus insuring complete'relaxation of the occupant while in. any position.
. The present invention consists in the provision of a stool wherein is embodied a rigid framestructure, a seat, a stem depending from the seat and an improved spring structure including radially extending springs which are adaptedto be connected with the frame and withupper and lower collars 5 loosely mounted upon the stem and said radially extending springs being supplemented by vertically disposed springs which connect an intermediate collar and the upper end of said frame and serve to resiliently support I the seat when the latter isoecupied. The
provision of the lower collar and the radially disposed springs is an improvement over my patent issued November 29, 1921, No. 1,398,- 938, and by means of the lowermost collar '35 undue side movement on the lower end of the taken on the plane indicated by the line 3-3 of Figure 1. y i
to the seat structure 5.
1929. Seria1N'o.359,243.
Referring more particularly *to the details of the invention, the numeral 1 designatesmy improved stool inits entirety. The stool consists of a suitable frame which in this instance is formed frommetallic channel mem bers 2 vertically disposed and unitedfby means of rigid cross-bars3. The channel members and the cross-bars may be bent to any suitable shape and formto give the stool a pleasing appearance and by means of this to i 1 .constructlon the frame 1s. rendered substan tially capable of withstanding hard and severe usage and atthe same time permits the stoolto be relatively lightin weightso that it maybe readily moved from one placeto lm another) 1 Centrally and vertically disposed within the framegstructureis a stem 4: having a "seat structure 5 mounted j at its upper end, thelatjter being of y Suitiible COnStruction and lif desired may embody an adjustable bac lirest 16.. Thelower portion ofthe stem asthmaed for a suitable distance, as indicated at7, for the reception of a similarly threaded spider or collar 8 in which thestemis adjustable for vertical movement. The spider or collar 8 is formed with radially projeting arms 9, whichhave their outer endsconnected with the lower ends of downwardly andyinwardly' sloping coil springs 9', the upper or 'outerends of said springs beingsecuredin any suitable manner to the corner members oftheframe 1. It willbe understoodthat these springs may be of any suitablesize and number. and are so positioned within the frame as to act together for the purpose of a receiving and absorbing weights imparted y Also carried by the lowermost of the I H.
stem 4.1 a thre'aded collar 10 identical in jshapetothat of the collar 8 Whiclrhas'itsi'adial arms 11 connected with radially projecting springs12. Thesprings 12 have their "outer endsconnected to thelower r ss-mew hers. This construction serves tosta'bilize the lower end ofthe stem and to preventun due side movements whentheseat is oceupied. Carried by the upper endsof the frame members 2 is aplurality of radially re -eaiagsprii1g-s nematars'sauaaa "to 2 upon the latter-is suddenl extend substantially parallel with the springs 12 ofthe lower collar 10. These springs 13 have their inner ends connected With the outer portions of radially extending arms 5 provided upon a collar 14. The latter is loosely positioned around the upper portion of the stem 4. This upper spring construction together with the collar 14: serves to centralize the stem t and to effect its resilient support within the frame structure. It will be observed that the springs connecting the upper and'the lower of said collars are anchored to the frame at a point substantially 45 apart. This preserves the equilibrium of 15 the stool and obsorbs the shock imparted to the seat from every angle, The collar 14 is heldin its proper position with respect to the stem 4 bymeans of a rebound or absorbent spring 15, surrounding the stem 4, and is positioned between the collar 14 and the collar 8. a V
By reason of the location of the spring 15 it will be seen that an upward movement on the .part of'the seat is arrested, when weight removed therefrom, and the operation 0 the stool is thus rendered automatic insuring the removal of jolts and shocks. It will be noted that by means of the lateral springs connected to the ,3 'upper and lower collars of the stem, lateral movement on the part of the seat is precluded and that the same "is resilient only with respect to the vertical. By providing a thread- .ed stem, adjustments in a vertical direction 3 may be imparted to the seat in order that the stoolmay be accommodated to the different heights required by difierent occupants. The lower endof the frame constituting the leg members for the stool may be equipped with is used in an ofiice, rubber buffers may be provided in place of the castors to prevent V marring the floors and to insure quiet when the stoolis moved.
,45 From the foregoing description taken in connection with the accompanying drawlng,
it Will be seen that there is provided an improved stool construction, wherein the mech- .anism is of such character as'to insure comfort to the user and longevity of the stool.
What is claimed is: c 1. A stool of the character described, comprising a supporting frame, a seat, a'stem dependlng from said seat and arranged vert1- cally and centrally of said frame, a collar loosely carried by the upper end of said stem,
anchored to the frame at a position intermediate tothat of said upper radial springs.
2. A stool of the character described, comprising a supporting frame, a seat, a stem depending from said seat and arranged vertically and centrally of said frame, a collar loosely carried by the upper end of said stem, a second collar threadedly received by the lower end of said stem, a third collar threadedly carried by said stem intermediate of said first named collars, a rebound spring surrounding said stem and exerting pressure upon said first named collars and said intermediate collar, vertically extending shock absorbing springs connecting said intermediate collar to the upper end of said frame, and a plurality of radially extending springs extending'between the upper and the lower of said collars and said supporting frame.
In testimony whereof I aflix my signature.
CHARLES F. MILLER.
40 roller castors 16 if desired. In case the stool p shock absorbing springs connecting the inter mediate collar to the upper end of. said frame,
