CHARLES JELLiNEK .AND yDAVID STERN, or` :NEW YORK, N. Y.

cisuiiiz.y

To all 'whom t may concern.'

Be it known that CHARLES J ELLiNEKfand DAVIDSTERN, citizens of the United States, residing in the city, county, and State of New York, havevinvented certain new and useful Improvements in Chairs, of whichnthe following is a specification.

r Our invention relates in general toza swinging chair forv use. in connection with sewing machine stands, 4counters and like places where itis desired to move the chair from an inoperative position into an operative seating position and particularly relates to 'such a device designed lto bezmounted onl a sewing machine 'stand or other support nor `mally subj ected to vibratorymovement.

One of the objects of the invention is'to providea simple formvof seat of the class described which can be moved quickly and easily into a seating position and which will i automatically remove itself from its seating c into an inoperative and out-of-the-way posif locked in position by the weight on the seat and which position will be maintained as long as there is any materialpressure on the seat and a still further object is to provide a seat which may be carriedby a vibratory member but which will itself be free of any vibration. ,v Y

Various other objects and' advantages kof the invention Lwill be in Palit Obvious from an inspection ofthe accompanying drawings andin part will be more fully set 'forth in the following particular descriptionV of one form of mechanism'embodyii'ig our invention, and the invention also consists in certain new and novel features ofconstruction and combination of parts hereinafter nset forth and claimed.

In the accompanying drawings: t

Application led -August 8, 1916. Serial No. 113,779.

Fig. 3'is ahorizontal sectional view taken on Vthe line 3 3 of Fig. 1 and showing Vin dot and dash lines,'the operative position of i ing position and shown swung Aat right f rangles to.the.positionillustrated in Fig. 1';

the device shown in side elevation in Fig.2; i

Fig 4 `is'an enlarged .vertical vsectional v1ew of the `swinging-bracket and support taken on the line /1-4 of Fig. 1 `and Fig. 5 is a transverse sectional view taken substantially on the line 5-.5 of Fig. 2.

In thefollowing description ,and in the claims, parts will be-identified byv specic .names yfor V convenience of expression but. .they are intended to be as generic in their applicationfto similar parts as the art willi permit. f In' the accompanying drawings, the lchair is showninthe form of an attachment de- 1' signed fto be supported from some suitable part 6 of a` work-table or frame-work of a jsewing machine or other suitable articleof furniture. vIn this disclosure Athe member 6 may be considered asapart of a machine structure subjected to vibrationand jars. A

support of any conventional `form is fas-f1 tened to the frame-work or part 6 as by means of bolts 8. The support includes threevertically spaoedhori'zontal plates 9, 1(7),Vv and 11,r projecting from one side ofthe support and coactively constituting a bear-f,

ing for a vertically disposed pivoting pin 12. A triangular shaped vertically disposed bracket 13 isrigidly connected to the pin 12 so as to swing horizontally about the pin as is defined Aby a relatively long horizontally disposed arm AlLf, pinned to and extending laterally from the upper end of the pivoting pin. 'The pivoted end of this arm rests upon the upper bearing plate 9, which is formed #into a boss '115 to support the same. -bracketincludes an inclined'brace or reach The member16, one end' of which is riveted to the larm 14 intermediate its ends. The lower end of the reach member is `connected tothe pin 12 adjacent Yits'lower end andisldesigned to resty on the lower bearing plateA 11. This lower bearing plate is provided with a plurality of socketsY 17 in the form of apertures disposed in an arc concentricallyl positioned about the aXis of rotation of the pivot pin.

VvThe portion of the reach member` 16 which rests on the lower bearing plate is provided with aprojeetion 1.8, the form ofA a pin, designed t0 vengage 111 any .one of `thesockets i a pivot. The upper portion of the bracket g to prevent swinging movement of the bracket about the aXis of thepivot pin whenV` the bracket and its seat are in depressed position. The bracket is normally held in raised p04 .sition, .so that theprojection is disengaged "from the sotket. Forthis purpose alifting spring 19 rests upon the; intermediate plate l() 'and bears against a collar 20 fixed to the pivoting pini between :the fupper Iand' intermediate plates..
