UNITED STATES PATENT FFIcE.

CHARLES H. COLBY, OF BROOKLYN, NEW YORK, ASSIGNOR TO J. COLBY & COJ, OF SAME PLACE.

OPERATORS SEAT.

SPECIFICATION forming part of Letters Patent No. 478,987, dated July 19, 1892.

Application filed September 1'7, 1891- Serial No. 405,952. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES H. COLBY, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New 5 York, have invented a certain new and-useful Improvement in Operators Seats, of which the following is a specification.

This invention relates particularly to seats for operators of sewing and other hand-con- IO trolled machines, although it is also advantageously applicable in various other situations, as at the counters, tables, and benches used in other occupations.

The objects of my invention areto provide for conveniently raising and lowering such seats for use and for putting them out of the way when not in use, and also to simplify, strengthen, and otherwise improve their constrnction.

The invention consists of a novel construction and combination of parts, substantially as hereinafter described and as claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which Figure 1 is a plan of one seat and part of another applied to a sewing-machine table in accordance with my invention. Fig. 2 is a side sectional elevation of the same on the line X X, Fig. 1. Fig. 3 is a front sectional elevation on the line Y Y, Fig. 2.

Like letters of reference designate corresponding parts in the several figures.

A designates part of a sewing-machine ta- '3 5 ble, and B a rigid leg or standard of the same located at one side of the machine.

In applying my improved operators seat to such a table the standard B is preferably formed in advance integrally with upper and 0 lower brackets C and D, which are formed with end socket-bearings C and D, opening, respectively, downward and upward. The bearings C and D are adapted to receive loosely the upper and lower ends of an up- 5 right pivot-bar E, and are so placed that the Fig. 3.

said pivot-bar will be slightly inclined upward and laterally toward the machine at which the operator is to sit, as best shown in On the inclined pivot-bar E is fitted to slide up and down a thick sleeve F, provided with a binding-screw G, to work against the bar E and formed integrally with a stiff horizontal arm H, which normally curves outward and laterally in the direction of the incline of the pivot-bar-that' is, toward the front of the machine before which the operator is to sit. On the extremity of the arm H is formed, by preference, integrally the seat J, facing the machine. The seat J can thus be swung, with the arm H, on the pivot-bar E to any desired position for use with respect to the machine, and can also be instantly adj usted, with the arm H, up and down the pivot-bar E and secured in position thereon by the binding-screw G. 6 5

When the seat-J is not in use, it, together with the arm H, will swing by gravity. under the table A, owing to the slant of the pivotbar E, and will thus remain out of the Way until used again. The described curve of the arm l-I causes it to join the seat at the side thereof, and thus be wholly out of the way of the operators legs, and also carries the seat more completely out of the way when not in use.

I claim as my invention The combination, substantially as hereinbefore set forth, of a table, a support thereof having upper and lower bearings, the line of which is somewhat inclined from the Vertical, a barpivoted at its upper and lower ends to said bearings,- a sleeve carryinga set-screw, fitted to slide up and down on said pivot-bar, and an arm rigidly attached to said sleeve and carrying at its outer end an operators seat J.
