WILLIAM O. LINCOLN, OF BRIDGEPOBT, CONNECTICUT, ASSIGNOB TO SAMUEL W. LAMBETH, OF PHILADELPHIA, PENNSYLVANIA.

FLY-FAN.

SPECIFICATION forming part of Letters Patent No. 228,466, dated .Tune 8, 1880.

Application Elea Maren eo, Iseo. (No model.)

To all whom t may concern Be it known that I, WILLIAM O. LINCOLN, a citizen of the United States, residing at Bridgeport, in the county of Fairlield, State of Connecticut, have invented a new and useful Improvement in Fly-Fans, which improvement is fully set forth in the following specification and accompanying drawings, in which- Figure l is a side elevation ofthe portion of a {Iy-fan embodying my invention. Fig. 2 is a vertical section of aportion thereof. Fig. 3 is a horizontal section in line a: a2, Fig. 2.

Similar letters of reference indicate correspondin g parts in the several figures.

My invention relates to an improvement in fans which have arms connected to a staff, the rotation whereof is occasioned by a train of gearing, after the manner of clock-work, the motion of the blades which are attached tov said arms serving' to frighten flies and other insects.

The invention consists in supporting the collar to which the fan-arms are hinged at any desired or adjusted height ou the rotary staff by means of friction-springs, which are simple in construction and reliable in operation, and' may be entirely concealed within the collar.

Referring to the drawings, Arepresents the staff or shaft, rising from'a stand or base, B, containing a mechanical power, such as clockwork, for rotating said staff, as is well known in the class of fly-fans.

C represents a collar, to which the arms D of the fan-blades are hinged, and which is iitted loosely on the staff A, so asto be raised and lowered relatively to theI height that it is desired to set the blades.

. Secured to the inner wall of one end of the collar are springs or spring-plates E, which converge so that their disconnected ends, preferably semi-cylindrical, bear at opposite places against the staff, and thus create friction for holding` the collar on the staff.

It will be seen that thecollar may be readily raised or lowered, in order to adjust the height ofthe fanblade, simply by moving or shifting it in the proper direction, and when it is set the springs bite the shaft, and thus hold the collar and parts without screws or other fastenings. Vhen the collar is in the form of a chamber the springs are furthermore inclosed thereby, and thus concealed and rendered inaccessible.

The friction of the springs is sufficient to cause the rotation of the collar with the staff when the latter is a plain rod 5 butif the staff is corrugated the upper and lower walls of the collar are scalloped to accord and engage with the corrugations of the sta-ff, without, however, interfering With the vertical adjustment of the collar. 1

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent is The fan-supporting collar, in combination with friction-spri n gs secured to said collar, and adapted to bear against the rotary shaft passed through the collar, substantially as and for the purpose set forth.

VILLIAM O. LINCOLN.
