resilient stools, and has for its primary ob ject to provide a stool of this character which is adapted for use upon street cars or other moving vehicles for enabling the operators thereof to remain comfortably seated while controlling the vehicles, this object being carried out by the provision .of an improved spring structure for such stools which serves to absorb the vibration and jar imparted to the vehicle and to thereby prevent the jolts and jars from interfering with the comfort of the operator.
The present invention consists in-the provision of a stool wherein is embodied a rigid frame, a seat, a stem depending from the seat and an improved spring structure between the frame and stem for the purpose of resiliently supporting the seat, the said spring structure including radially eXtending springs which are adapted to be connected with the frame and with collars loosely mounted upon the stem, and said radially extending springs being supplemented by a plurality of vertically disposed springs, which connect the lowermost of said collars with the upper part of said frame and serve to resiliently support the seat when the latter is occupied.
Another object of theinvention resides in improving the construction of the stool disclosed in the copending application of Albert Miller et all, Serial Number 339,363,-
filed November 20, 1919, which application the present applicant is an assignee of the title thereof.
In the accompanying drawing:
Figure 1 is a side elevation of the springs 2 comprising the present invention,
Fig. 2 is a vertical longitudinal sectional View taken through the stool, and
Fig. 3 is a horizontal sectional view taken along the line 3-3 of Fig. 1.
Referring more particularly to the details of the invention, the numeral 1 designates my improved stool in its entirety, as shown, the stool consists in this instance of a metallic frame 2, which may be formed from Specification of Letters Patent.
Patented Nov. 29, 1921.

substantially vertically disposed angle bars 3, which are united by means of rigid cross bars 4. This construction serves to render the framesubstantial in construction, capable of withstanding hard and severe usage and at the same time permits the same to be relatively light in weight so as to be readily handled. i
The stool further includes'a seat 5, of.
any suitable design or construction, in the form of the invention illustrated the seat belng deslgned for the use of the o aerator of a passenger carrying vehicle, but it will be apparent that the seat may also be used in drafting rooms, in connection with book-- keeping ofiices, cashiers desks andin very many other different occupations. The seat 5 in this instanceis provided with a depend-v ing stem 6, which is rigidly secured as at ,T.
to the under surface of the stool, the said stem being adapted to extend downwardly and vertically through the frame 2, and has its lower end threaded for a suitable distance as at 8. Arranged to be threadedly carried by the lower end 8 of the stem is a collar 9 that carries radially projecting arms 10, which arms have their outer ends connected with the inner ends of radially disposed springs 11. These springs are disposed to incline downwardly and outwardly, and have their outer ends secured in any suitable manner to the frame 2, the said springs 11 serving to center the positions of the lower ends of the stem and also to absorb a part of the weight placed upon the seat 5.
However, to absorb the greater part of the weight which will be placed upon the stool, I employ substantially vertically disposed springs 12, which have their upper ends connected with the upper portion of the frame 2, and have their lower ends connected with the outer ends of the arms 10 immediately adj acent to the inner ends of the springs 11. It will be manifest that by reason of this construction when weight is deposited upon. the seat 5, the stem will move downwardly a distance resiliently limited bythe cooperative action of the springs 11 and 12. Also, carried by the upper end of the frame is a plurality of radially projecting springs 13, which are situated to extend parallel with the springs 11. These springs 13 have their inner ends connected with the outer portions of radially extending arms provided upon a around the upper portion of the stem 6. The spring structure described serves through the instrumentality of the collar 9 to efi'ect the resilient support of the seat structure,
and provides a very efiicient construction for this purpose. T he collar 14 is main tained in its proper position with respect to the stem 6 by providing a rebound absorbing spring 15, which surrounds the stein G and is positioned between the collars 9 and 14. It will be seen that the spring 15 by reason of its location and cooperation with the collars 9 and 13 will serve to arrest sharp upward movement on the part of the seat when weight upon the latter is suddeiilyreleasecl orremoved, and also to renderthe operation of the spring structure generally smooth, uniform and devoid of intermittent or jerky movements. Another feature found in the present invention by'the use. of the horizontal springs 11 and 13 is the lateral movement which may beimparted ina limited degree to the seat. In the apphca'taon above referred to the seat is only resilientwith re-,
spect to the vertical, the stem being gripped in such manner as to preclude lateral movement on the part of the seat in any degree. However, it will be manifestthat whilethe springs 11 and 13 will serve normally to maintain the stem within the center of the frame, yet they do not afford the slight lateral motion mentioned, a feature which is of marked advantage for the operators of common carriers.
W- Vhat is claimed is: 7
1. A stool of the character described comprising a supporting frame, a seat, a stem depending from said seat, said stem being provided with a threaded lower portion, a member threaded to the lower portion of said stem and permitting of vertical adjustment onthe part of said seat, asecond member loosely carried by said stein above said firstnamed member, a rebound spring positioned between said members and serving to space the latter, and a'plurality of shock absorbing springs extending between said members and said supporting frame.
2. A stool of the character described com prising a supporting frame, aseat, a stem depending from said seat and arranged vertically and centrally of said frame, a member capable of threadedly receiving the lower end of said stem, a second member loosely carried by said stem above said first named member, a rebound rounding said stem and exerting pressure upon said members to separate the latter, and horizontal and vertical extending sp rings carried by said frame and having the inner ends thereof connected with said members.
