UNITED STATES PATENT vQFFICE.
THOMAS GREEN, OF BROOKLYN, NEW YOR-K, ASSIGNOR TO HIMSELF AND HENRY- A. BOWDOIN, OF SAME PLAGE.
IMPROVEAMENT'IN FAN ATTACHMENTS FORSEWING-MACHINES.
Specication forming part of Letters Patent No. 116,303, dated June 27, 1871.
erence being had tothe accompanying drawing forming part of this specification.
This invention relates to a new and useful addition to sewing-machines, the design of which is to render the operator more comfortable during hot weather orina heated atmosphere, by agitating the air by fanning; and the invention consists in attaching a fan to the machine, so arranged as to be operated by means of the treadle, or so that the same power which operates the needle of the machine will impart motion to the fan, as will be hereinafter more fully described.
In the accompanying dra-wing, Figure l represents a sectional end elevation of a sewing-machine. with the fan attached. Fig. 2 is a detailed view-of the mechanism by which the fan is vibrated.
Similar letters of referenceindicate correspond ing parts.
A is the sewing-machine table. B is a socketstand, secured in a boX, C, in the table, resting on a shoulder, as seen in the drawing, with a slotted arm, D, in its lower end, beneath the table. E is the stai' of the fan, which is placed in the socket B, as represented, where the friction is sufficient to hold it in place, or it may be secured and prevented from turning in the socket by means of a small set-screw, or by any other means. The socket-stand B is given an oscillat ing or vibrating motion, so that the motion ofthe fan will resemble that given to the common handfan. This may be done by any mechanical arrangement suitable for -the purpose. In this eX- ample of my invention I employ Vthe slotted arm D on the end of the stand B, in connection with a bell-crank, F, which bell-crank is pivoted to a stand on the under side of the sewing-machine table, or otherwise secured in a proper position, so that a vrod may extend therefrom to a crank on the iiy-wheel, or to the treadle, as may be found most desirable or convenient.
I do not confine myself to this particular method of actuating the fan. I am aware that other means may beadopted for giving motion to the fan by the same power which operates the machine. This motion may be a horizontal vibrating motion, as represented, or a vertical, oblique,
or rotary, or any motion imparted to a fan of any description from the operating parts of a sewingmachine.
Having thus .described my invention, I claim as new and desire to secure by Letters Patent- In combina-tion with a sewing-machine, the fan mechanism, consisting of the socket B, slotted arm D, and pivoted bell-crank lever F, all operating substantially as herein shown and described. Y
The above speciiication of my invention signed by me this 18th day of February, 1869.
