FAN ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 619,508, dated February 14, 1899.

Application filed December 23, 1897. Serial No. 663,229. (No model.)

To a whom it may concern:

Be it known that I, ALPHEOUS RUSSELL, residing at Wickliffe, in the county of Ballard and State of Kentucky, have invented a new and useful Improvement in Fan Attachments for Sewing-Machines, of which the following is a full, clear, and exact description.

My invention is an improvement in fan attachments for sewing-machines, and has for an object, among others, to provide a simple effective construction by which the fan may be operated from the fiy-wheel of a sewingmachine and may be quickly adjusted into and out of operative connection therewith and may be adjusted out of the way of the sewing-machine case, so the latter may be applied when the fan attachment is out of operative connection with the sewing-machine; and the invention consists in the special constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a front view of my improvement as in use. Fig. 2 is a detail vertical section, and Figs. 3 and 4 are detail cross-sections.

In carrying out my invention I provide a shaft A, preferably vertically disposed, as shown, and provided with a friction-wheel D, having a rubber or similar tire D and suitably journaled so it may be turned. This shaft also has a clamp G to secure the fan D, which latter may be of the common palmleaf variety. The clamp 0 includes a spring plate E, secured at one end E to the shaftA a short distance below the upper end of said shaft and arranged at its other end to press the handle of the fan against the shaft A, the latter being grooved or concaved at A to receive the rounded side of the fan-handle.

The shaft A is journaled in a suitable support, which support is so pivoted that the shaft may be swung on the arc of a circle to set its friction-wheel into and out of engagement with the fly-wheel of the sewing-machine. The support for the shaft A includes a bracket F, having upper and lower wings F F and a wing connecting such upper and lower Wings and secured by a bolt G and wing-nut G to the standard H, which latter is pivoted at H to the base and has at its upper end the crank portion H which forms an eccentric support for the fan and its bracket, so the fan may be swung into and out of operative connection with the Wheel of the sowjug-machine.

In the construction shown the standard is journaled to the base I and is provided with a handle dog or pawl J, which is preferably springy, so it may engage with the notches K or K. When engaged with the notch K, the dog holds the fan attachment out of operative connection with the sewing-machine, while the engagement of said dog with the notch K holds the friction-wheel in engagement wit-h the fly-wheel of the sewing-machine. It is preferred to provide the notches K in series, so the friction-wheel may be caused to bind with more or less tension upon the fly-wheel of the machine.

In order to secure a vertical adjustment of the fan-shaft to aid in accurately setting the latter to bear against the fly-wheel, I prefer to provide the standard H with a slot h for the passage of the bolt G, so the bracket may be set higher or lower.

In practice the base I is secured to the table of the machine by screws, as shown, orin other suitable manner in such position as to permit the friction-wheel to be thrown into and out of engagement with the liy-wheel of the sewing-machine, the construction previously described serving to secure the fanshaft in gear with the fly-wheel or out of such gear, at the will of the operator. This connection and disconnection of the fan-shaft is effected without disarranging the support of the standard, may be quickly effected, and the standard is secured in both adjustments by the dropping of the dog into proper notches.

In securing the bracket it will be seen the bolt Gforms a pivot upon which the bracket may be adjusted to set the fan-shaft in any angle or position desired by the operator. The pivot G is also adjustable in the slot h of the bracket, the pivot and the 'slot construction cooperating in securing a proper bearing of the wheel D against the fly-Wheel of the machine in the different adjustments of the bracket.

While it is preferred to use a palm-leaf fan and to secure it as shown, it is obvious that other similar fans may be used, or different forms of fans may be used adapted for operatin g by a rotating shaft.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is-

1. A fan attachment comprising a standard, a bracket having upper and lower wings provided with bearings and a wing connecting and pivoted between said upper and lower wings to the standard whereby the bracket may be adjusted, means for securing the bracket in any adjustment and the fan-shaft journaled in said upper and lower wings substantially as set forth.

2. The fan attachment herein described consisting of the base the standard pivoted thereto, means whereby the standard may be held in any desired adjustment, such standard havset forth.

ALPHEOUS RUSSELL. WVitnesses:

A. J. GRoss, E. H. SMITH.
