Abstract

415,138. Chairs; adjustable backrests. BURROUGHS ADDING MACHINE CO., 2nd Avenue, Detroit, Michigan, U.S.A. Feb. 23, 1933, No. 5568. Convention date, May 31, 1932. [Class 52 (ii).] In a metal chair with an adjustable back-rest 31 supported on a curved standard 14, the latter is slidably mounted in a sleeve 13 which is pivotally connected to the seat in a slot in the rear edge thereof, and means are provided for holding the standard 14 and the sleeve 13 in adjusted position, preferably in the form of a pair of links 42 pivoted to the seat support 2 and extending rearwardly on each side of the sleeve 13, against which they may be clamped by means of a bolt and wing nut 44. The seat may be formed of a metal core 3, to which is welded a metal plate 5, a cushion 6 being fixed to the plate 5. The sleeve 13 is of rectangular section, and is pivoted on a pin 12. The back-rest standard 14 is provided with openings 19 into which a spring-pressed pin 20 is adapted to enter to hold the back rest in vertically adjusted position. The depending arms 40 of the sleeve 13 are arranged so as to grip the lower part of the standard 14 when clamped to the links 42. The back-rest 31 may be adjustable angularly by means of a thumb-nut 32.
