WHLqEEEEE lUNiTE STATES JOHN M. GLEASON, OF LOWELL,

TO JAMES H.

PATENT O FIGE.

MASSACHUSETTS, ASSIGNOR OF ONE-HALF MODERMOTT, OF SAME PLACE.

SPECIFICATION To all whom, it may concern: l

Be it known that 1, JOHN M. GLEASON, a citizen of the United States, residing atLowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Sewing- Machine Fans, of which the following is a specification.

My invention relates to a fan, supported upon the table of a sewing-machine, or other light machine driven by foot-power, and adapted to be operated by the motion of l the treadle of the machine. 1

In the accompanying drawings, Figure 1 is an oblique view of a sewing-machine table with my invention attached. Fig. 2 is an enlarged elevation, showing the method of attaching the bell-crank lever and its support to the table, the fan-socket being in section; Fig. 3, an enlarged elevation of the lower bracket attached to the treadle. Fig. 4 is a front elevation of parts shown in Fig. 8, representing the method of attaching and adjusting the connecting-rod.

A'is the frame; B, the table; 0, the treadle, l rocking up on the shaft D, and connected at its rear end by the pitman to the wrist E on the l fly-wheel F, from which fly-wheel a sewingmachine (not shown) supported on the table B is driven in the usual manner.

The above-named parts are of the usual construction and operation.

A bracket, G, has an open or forked end, 9 g, which receives the back edge of the table 13, and a set-screw, G, turning in the lower tine, g, of the fork, thrusts against the under side of the table and secures the bracket G to the table. To the rear end of the bracket G is pivoted at G a bell-crank lever, H. The upper arm of the lever H is provided with a hollow or socket, H, in which the handle I of a palm-leaf or other fan, I, of similar shape, may be inserted. The handle I is retained in the socket 11 by a set-screw, J, which turns in a threaded hole in the side of said socket, and thrusts against said handle I. A bracket, K, similar to the bracket G, is forked at k k to take in the back edge of the treadle.

under side of the treadle G, or directly against the treadle, and holds the bracket K in place. A connecting-rod, L, is pivoted at the lower end, at L, to the outer end of the bracket K, and at the upper end, at L", to the outer end eration of the treadle in the usual manner to drive the sewing-machine will give a reciproeating motion to the bellcrank lever H and to the fan I,-and direct a current of air upon the operator, who sits at the front of the table.

The outer endof the lower bracket, K, is provided with an extension, K in which are a number of holes, 0 0 0 into either of which of the lower arm of the lever H; hence the opthe pivot may be inserted, according as the height of the table above the treadle is greater or less, it being intended that the handle I of the fan shall stand about perpendicularly when the fan is thrown back as far as possible.

ble by the holes 0 O 0 I can apply my fan to any of the sewing-machines in commonuse. Each of the set-screws G J K should turn in a boss or thickened spot on the part which it enters, in order that such light as possible.

Each pivot G L L consists of a nick-headed screw, which is smooth and cylindrical next its head and within the part which turns upon it, and is of reduced size near the point and threaded, as shown in Fig. 4, the shoulder Z, Fig. 4,'between the smooth part and the threaded part, preventing the pivot from entering far enough to bind the piece which turns upon it.

The lower bracket, K, may have a recess at K to receive a rib or bead, G, such as is frequently cast around the edge of the treadle.

The fan above described operates only when the machine to which it is applied is in morequire any great additional outlay of power to run it, requires no winding up or stopping, and is much cheaper than the clock-work fans sometimes used for a similar purpose. ,1

I claim as my invention- 1. The combination of the table and the treadle, a bracket, means of securing the same to said table, a bell-crank lever pivoted to the said bracket and adapted to receive the ban means of the adjustment rendered possi- 0 parts may be as dle of a fan, another bracket and means of seadjust-ably attaching said connecting-rod to 10 curing the same to said treadle, andaconnectsaid bracket, and means of attaching said ing-rod pivoted to said lever and to said last bracket to the treadle of a machine, as and for named bracket, as and for the purpose spccithe purpose specified.
