FAN.

SPECIFICATION forming part of Letters Patent No. 278,799, dated June 5, 1883.

Application filed February 28, 1883. (No modeLl Be it known that'I, FRIEDRICH KINN, of the city, county, and State of New York, have invented certain new and useful Improvements in Fans, of which the following is a specification.

This invention relates to improvements in spring-fans, or 'fans of that class in which the web of the fan is spread out or opened by a spring appliedto the center pivot and one of the released from the handle; and the invention consists ofa forked handle, to the ends of which is centrally pivoted a folding web provided with end plates, one of which is retained in a sliding and spring-acted casing at the base of the forked handle, while the other is adapted to clear said casing. The end plates of the web are connected by a spring that engages a transverse stay-pin of the pivoted center disks of web, so as to spread the web into open position whenever by the release of one of the end plates the connectingspring is permitted to actuate the web.

In the accompanying drawings, Figure 1 represents a vertical transverse section of my improved fan, shown with the web in open position. Fig. 2 is a side view, partly in vertical section, of the fan with the web in closed position. Fig. 3 is a sectional end view of the fan closed, and 4 is a horizontal section on line a, Fig. 1.

Similar letters of reference indicate corresponding parts.

A represents the handle of my improved fan, the upper part of which is forked, so that the space between the forked portion or casing can be utilized for receiving the folded web B. The web is made of radial plaits or folds in the customary manner in fans of this class. The folds at each end of the web are strengthened by end plates or leaves, I) b, of wood, sheet metal, or other suitable material. The folds of the web B are held together by disks (2 d, that are cen' trally pivoted to the outer end of the forked handle A, said disks being connected by fixed transverse pins d d, to which the end plates, 1) b, are applied. The end plates, b b, are made of different length, one being somewhat longer than the other, both being engaged by a slidby a spiral spring, 6 interposed between the pin e and the base of the forked handle, as shown clearly in Figs. 2 and 3. l Vhen the casing O is drawn back away flom the web of the fan, the shorter end plate, I), is permitted to pass clear of the casing and swing around the center pivot of the web to the other side of the handle, by which motion the web is spread into open position. By returning the end plate the web is folded up again, itbeing engaged in either position by the sliding and spring-pressed casing C, which forms the fastening device for the end plates, b. Both end plates, 1) b, are connected by a rubber or other spring, D, that extends first along one end plate,

I), then between the disks (1 d, and along the opposite end plate, I). The spring D is re tained between the center disks, d (1, by a fixed transverse pin, located intermediately between the stay-pins d d of the disks. The springD serves to engage the pin f of the disks whenever the shorter end plate, I), is permitted to clear the casing C, so as to produce thereby the turning of the center disks and the opening of the web until the end plate arrives at the other side of the forked handle and is re-engaged by the spring-casing C. By the tension of the spring D on the pin f it is carried with the center disks, (1 (Z, around the pivot-pin (1 until the pin f arrives at a position below the pivot (1 but diametrically opposite to its former po- 8 5 sition above the same, as shown in Fig. 1.

The web B is held in open position by the action of the spring and the retaining action of the casing C. For closing the fan the shorter end plate, I), is released again from the casing 0 and swung around the pivot of the web until it arrives at the opposite side of the casing C,

by which motion the spring D is expanded and the center disks, (1 d, with their transverse pin,

returned to their normal position, as shown in 9 5 in Fig. 2. The fan is consequently thrown into open position with great facility by the action of the spring on the end plates, b b, and the center disks, (1 cl, by simply releasing the shorter end plate by drawing back the casing C and allowing it to re-engage the end plate when the web is opened, all of which is accomplished by the action of one hand, as the thumb and index-finger operate the casing, while the remaining fingers take hold of the hand. For closing, the casing hasto be drawn back and the web returned into folded position by tak ing hold of the end plate with the other hand.

I am aware that fans which are thrown into open position by the action of a spring applied to the web and the center pivot of the same are old and well known. I am also aware that a forked fanhandle in which the web is pivoted to the outer end of the forked portion and arranged with end plates, one of which is retained at the base of the forked portion, while the other is free to swing from one side to the other of the handle, to be then locked by fasteningdevices of the forked handle, is also well known, and I therefore distinctly disclaim these features. 7

Having thus described my iiwention, I claim as new and desire to secure by Letters Patent- As an improvement in a fan, the combination of the disk and web with the elastic spring-band D, the transverse stay-pin f, the end plates, b b, and the sliding casing 0, substantially as described.

In testimony that I claim the foregoing as my invention I have signed my name in presence oftwo subscribing witnesses.
