G. B. TRAVIS ADJUSTABLE CHAIR SEAT Filed Feb. 15. 1928 Nov. 12, 1929.

INVENTOR G'e yeB.Tm /5,

ATTORNEY Patented Nov. 12, 1929 UNITED STATES PATENT OFFICE ADJUSTABLE CHAIR SEAT Application filed February 15, 1828. Serial No. 254,479.

This invention relates to adjustable chair seats, and it has for its primary object the provision of a device of this character which can be used satisfactorily in connection with lunch counters or the like and wherein the seat is characterized by means that will permit of quick and convenient adjustment thereof with respect to the counter, enabling the occupant to be comfortably accommodated when eating from the counter, and

whereby the occupant, when desiring to Vacate the seat, may effect actuations or adjustments thereof to afford maximum clearance between the seat and the counter.

A further object of the invention resides in the provision of a seat of this character having means whereby it can be adjusted to suit varying requirements and wherein, and when the seat occupies a position of selected adjustment the wearing apparel of the occupant will not be apt to be caught between the seat and the counter or become accidentally entangled with the seat.

A still further object of the invention is to provide a seat of this character which can be used in conjunction with lunch counters or tables and wherein the seat is provided with means for normally maintaining a position of adjustment thereof with respect to the counter and in alinement with positions of, other seats of the same kind, thereby giving uniformity or order in the arrangement of the respective seats for an appeal to the esthetic. A still further object of the invention is to provide an adjustable seat characterized by working parts that will be practically noiseless when in use.

A still further object is to provide ade- 0 vice of this character which can be used in conjunction with well-known forms of vertical seat-supporting standards or pedestals.

In the accompanying drawings,

Figure 1 is a top plan View of the seat with 5 a part broken away for the purpose of clearness;

Figure 2 is a view in side elevation showing the seat supported from a standard or pedestal, parts being broken away for the purpose ofclearness;

Figure 3 is a bottom plan view with parts in section;

Figure 1 is a transverse section taken substantially on the line 44 of Figure 3.

In carrying the invention into practice, use is made of a seat mounting 5, preferably formed of sheet steel, and provided with a horizontal body portion 6 and parallel side flanges 7, 7. In plan View, the body 6 is substantially rectangular and adjacent to each corner of the body and permanently carried thereby is a journal box 8. These journal boxes function as hangers for lower anti-friction rollers 9 and upper anti-friction rollers 10. These rollers may be constructed of rubberl, steel or other suitable well-known materia Extending in a downward direction from the center of the body 6 is a pin 11 which is adapted to be inserted in a recess 12 in the upper end of a pedestal 13. The pedestal is of the type carrying a base flange 14 adapted to be secured by the fastenings 15 to a floor. The pin 11 may be associated with the standard 13 in any suitable well-known manner, so that the seat roper, which I will refer to presently, can e revolved around the axis of the pedestal.

A track structure is illustrated at 16 and same comprises either a casing formed of sui table material or a sheet of steel llp-StIllCk to give to the structure a substantially rectangular configuration. The track structure is provided with parallel spaced-apart

U-shaped rails

17, 17, the upper flanges 19 of which form surfaces over which the rollers 10 are adapted to ride and the lower flanges :20 of which form similar surfaces for the free support of the rollers 9. If desired, the rollers 9 and 10, likewise the track structure, may be formed of compressed fiber, so as to render the parts practically noiseless when in movement. The respective ends of the track structure 16 are provided with elastic bumpers 21 which are adapted to come in contact with the seat mounting so as to absorb the shocks and jars imparted to the parts and reduce the noise when the parts are thrust against one 'another.

, At one end the track structure is provided with a spring or other yielding means 22 which is operatively associated with the mounting 5, so that the seat proper is normally urged in one direction. In this manner and when a number of the seats are arranged, say, in a parallel row, alinement thereof can be effected automatically.

From the recitation of parts herein advanced it follows that the seat is at all times under the manual control of the user. When it is desired to be accommodated by the seat, the operator merely advances pressure thereagainst in order to give the desired clearance between the forward edge of the seat and an adjacent edge of the counter with which it is associated, so that ample clearance is had to permit the occupant to comfortably arrange himself at the counter. On leaving the seat, the occupant merely impels the same in a direction following the urging power of the spring 22 until the desired clearance is had between the forward edge of the seat and the counter.

I claim as my invention:

An adjustable seat comprising a seat mounting constructed to provide a horizontal body portion of rectangular outline having a pivot pin depending therefrom and adapted tobemountedinapedestal,parallel sideflanges depending from the body portion, journal boxes on the flanges at opposite ends thereof and projecting from the outer sides thereof, upper and lower rollers rotatably mounted in the journal boxes, and a track structure adapted to be secured underneath'a seat and constructed to provide a rectangular shaped frame having end members and parallel spaced apart U shaped rails having upper and lower horizontal flanges, the seat mounting being interposed between said rails, with its upper and lower rollers interposed between the upper and lower flanges of the rails for rolling contact with the flanges, the end members of the track structure operating to definitely limit the movement of the track structure on the seat mounting in either direction, and cushioning elements on the end members adapted to engage the seat mounting.
