YORK, ASSIGNOR TOPERFECTE. Z. CHAIR CORPORA non, or Naw'roax, 1v. 2., a conrona'non or new roux I own Application filed January 16, 1929. SeriaLNo. 332,873.;

This invention relates to chairs and particularly to what are known as automatic reclining chairs; and theobjectof the invention is to provide a chair of the class described, with means on one of its pivots for introducing friction to control the'automatic operation of the back and seat members of the chair-to suit the comforts and desires 'of its occupants in movingthe back and seat into their several positions; a further object being to provide means for forming the finish of the upholstery and facing between the se eral cooperating chair parts so as to produce a neat and finished appearance; a further object being to provi'de means for gui ing the seat member in its movement forwardly and backwardly with respect to the chair frame proper, especially in overstufi'ed chairs of the class under consideration; a further object being to provide the seat member of the chair with a compara tively thin forwardupholstered end portion and a heavier upholstered rear end portion to compensate for the weight displacement of the body of a person in using the chair; and

with these and other objects in view, the inlvention-consists in a .device of the class and for the purpose specified-which is simple in construction, etlicient in use, and which is constructed as hereinafter I described and claimed. e The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:--

'Fig. 1 is a transverse, sectional View through a'cha'ir made according to my invention and indicating a method of its use.

3 2 is a section on the line 2,2"of Fig. 1.

Fig. 3 isa rear view of the chair.

' Fig. 4is-a sectional, detail view of a part of the construction, the section being on the line 4-4 of Fig. 3.

Fig. 5 is a partial section on the line 5-5 of Fig. 6 is a sectional, detail view of the backrest pivot.

Fig. 7 is a sectional detail view of the pivotail coupling between the backrest and seat; an 7 Fig. 8 is a view similar to Fig. 7 showing a modification.

In the accompanying drawing, I have shown an overstuffed chair or a chair of the upholstered type, In the drawing, 10 represents the main framework of the chair sup ported upon four legs 11 of any desired form orcontour, the frame consisting of a front rail 109, side rails 10 and a back rail 10. .Upon this frame are upright side frame members forming the arm portions 12 of the chair, 7

said arm frame being stuffed, padded or other- 'wise upholstered and including in the construction shown, suitable fabric facings 12, {prming-enclosures for the padding 12, note Mounted in connection-with the rear upright members of theframe 12 are reinforcing plates 13 for reinforcing'the support of pivot pins or screws 14 mounted in connection with said frame. The screws 14 are in threaded engagement with the. plates and form pivots for the backrest 15 of the chair, the side frame members 15 of'the backrest being rotatable ion the inner ends of said pivots. As noted in Figs. 2 and 3 of, the drawing, the upper portion of the backrest is enlarged so as to .overlie the rear end portions of the arm' frames 12 as seen at 16, the lower portions of the backrest fitting Within the arm frames 12 as clearly seen.

I The backrest is upholstered in the same manner as the arm frames and includes a suitable padding 15 contained within a fabric facing 17 of any suitable material. The part 17 of the facing, which is arranged at the back or rear face of the backrest 15, extends onto and is attached to the rear rail 10 bf the frame, forming a cover 17 b for the back of the chair from the pivots 14 downwardly to conceal the lower portion of the backrest and yet not interfere with its reclining movements. This is accomplished by attaching the upper edge of the part 17 to the arm frames-12 at a point in line with the pivots 14 as seen at 18, Figs. 1 and 3, so that the part of the sheet 17 a which covers the reduced portion of the backrest above the pivots 14 as indicated at 19,.Fig. 3, is free to move backwardly without danger of tearing or rupturing the corner 2 portions 20.

. ate.

The side frame members of the backrest project at their lower ends beyond the upholstered portion thereof. Mounted in connection with said ends are pivot pins or screws21 in connection with which bracket plates '22 secured to the seat member 23 or the side rails 23 thereof are adapted to oper- Said bracket plates have I apertures through which the pins 21 pass, and in practice, I arrange on said pins adjacent the frames 15*, metallic washers 24 between which and the .bracket plates 22 are" other washers of yielding material 25, such for example as rubber, fibre or soft metal. Suitable nuts 26 in threaded engagement with the screws or pins 21, are employed to support the brackets 22 in position and to regulate the frictional engagement of the several washer surfaces with each other and the sup ports 15, and 22, so as to control and regulate the chair operation.

In Fig. 8 of the drawing, I have shown a slight modification of the structure shown in Fig. 'Lwherein aspring 27 is mounted upon the pin or screw 21 between the plate 22 and the nut 28, which in said figure is of the wing type. In this construction, the

spring 21 takes the place of the washer and .by adjusting the tension of the spring,

the frictional engagement of the res ective parts .15 and 22 may be regulated.

form of frictional meansmay beemployed between the pivotal connection of the parts 15 and- 22, and while this construction is v shown arranged on the pivots 21, the same result may be accomplished by providing frictional means on the pivots 14 between the arranged at a higher plane than the wall member 30 to form a thinner front end portion in comparison with the rear end portion of the seat member so that the upholstery 23 of the seat member becomes heavier at its inner endthan at the forward end. On the lower surface of the bottom wall 29 and extending forwardly andbackwardly are two guide rails 31 which guide the seat nrember in its forward and backward movement, said rails fitting in notches 32 formed in the front rail 10 or a plate 33 secured thereto. It will also be noted that the front cross bar of the seat member 23 strikes upon the plat/e33 to limitthe inward or backward movement of the seat member. The ofiset or shoulder 34 is arranged intermediate the walls 29 a'nd 30 and also engages the plate 33 to limit the forward'or outward movement of the seat memt this time, it will be understood that any other.

her, the rails 31 being arranged forwardly of the shoulder 34.

'It will be noted that the inner end of the seat member is also joined to-the lower end of the backrest through a flexible strip or sheet 35 similar to the sheetings or facings employed in the upholstery to prevent articles from passing downwardly through the'chair between said parts, and also to form a neat and finished appearance. However, my inact said friction,permitting the occupant of the chair to move about freely without danger of displacing the adjusted position of the chair, but by exerting force or pressure, the chair may beadjusted to other positions to suit the comforts of the occupant, thus avoiding free automatic adjustment of the chair, involuntarily brought about by the movement of the occupant, which has been found to be objectionable'and has introduced a certain amount of tension and care on the part of the occupant in the use of the chair, which is avoided by the frictional means employed.

It will alsobe understood that while I have shown certain details of construction for carrying my invention into 'effect, and have shown a chair of specific type, that m' invention is not necessarily limited in t ese rcspects and various changes therein and modifications thereof maybe made within the 3 scope of the a pended claims-without departing from t e spirit of my invention or crificing its advantages.

Having fully described my invention, what I. claim as new-and desire to secure by Letters Patent, is
