UNITED STATES PATENT OFFICE.
STEPHEN C. OSGOOD, OF GEORGETOWN, MASSACHUSETTS.
IMPROVEMENT IN OSCILLATING CHAIRS.
Specification forming part of Letters Patent No. l 79,597, dated July 4, 1876; application Iled February 14, 1876.
To all whom it may concern Be it known that I, STEPHEN C. OSGOOD, of Georgetown, in the county of Essex and State of Massachusetts, have invented a new and Improved Rocking-Chair, ot' which the following` is a specication In the accompanying drawing, Figure l represents a front elevation of my improved .rockin g-ch air 5 and Fig. 2, a vertical transverse section ofthe same, on the line c c, Fig. l.
Similar letters of reference indicate corresponding parts.
The inventionV is designed to furnish an improved rocking motion for chairs, carseats, wagon-seats, cradles, Ste., by which an easy and pleasant swinging of the seat is obtained, while the simple and substantial construction provides a solid and reliable rocker.
The invention will first be described in connection with drawing, and then pointed-out in the claim.
In the drawing, A A are the standards of my improved rockin g-chair, which have broad base parts to give a firm and substantial support. The standards A are laterally connected by stii'eningrods a, securedv by screw and jam nuts. In heavy chairs the standards may be placed on casters, so as to be more readily moved about. The seat-carrying frame B swings, by knife-edged pivots b, on the springcushioned bearings d, seated in the upper parts of the standards, the spring-cushioning being produced by either spiral springs or rubber, as desired. The bearings are recessed toward the rear part ot' the chair, to admit the ready backward yswin ging of the seatframe B. The cushioned bearings d and pivots b are securely inclosed by top bearings d and casin gs c, that keep out the dust and prevent the detaching of the swinging seatframe.`
The seat is applied in any suitable manner to the bracket-shaped top ends of the seat-frame,
to lower en'ds of which the spiral rockingl springs C are applied. The spiral springs C are attached to the seat-trame and standards, and impart the rocking motion to the seatframe by the expansion and contraction of the springs.
The action of the chair is perfectly noi-selcss and easy, and does not admit the tipping forward beyond a certain point when sitting on the front part ot the chair, which feature recommends it especially for office purposes. The springs are not liable to break'or get out of order, and may be replaced without difficulty.
The giving ot' the seat, by means of the cushioned bearings, when sitting down produces a pleasant spring motion, and prevents the abrupt seating which would'be the case without this spring action.
The solid and simple construction ot' the vchair renders the same durable, and a rocking
