FAN PROTECTOR Fiied May 26, 1950 9 Tree/(46m gether.

Patented June 9, 1931 EMMA K. cooK, or

"r oFFrcE ST. LOUIS, MISSOURI ran reo'rnctror.

Application filed May 26,

is to provide a new and improved method of fastening the rear portion of the protector to v the cylindrical body of the protector.

In the drawings, 7

Fig. 1 is a side elevation of a fan enclosed by my protector.

a Fig. 2 is a view similar to Fig. 1 viewed from the front.

Fig. 3 shows the divided disc for enclosing the back part of the fan.

Fig. 4 is an enlarged detail view of the means for fastening the divided disc to- Fig. 5 is a cross-section along the line 55 in Fig. 3.

Fig. 6 is an enlarged view of the method of holding in place the disc shown in Fig. 3.

Electric fans are made in many types and sizes for domestic purpose where it becomes necessary to enclose the blades of the fan to prevent accidents to children as well as grown-ups. My former invention difiered from the present invention in that the edges of the wire mesh composing the protector were bound with cloth and fastened together with snap fasteners, the result being that the cover lacked rigidity, hence in the present invention 1 have supplanted the cloth binding with a bi-folded metal strip for joining the various parts of the protector together.

The present invention consists of a cylindrical portion 1, a front portion 2 permanently joined to said cylindrical portion, by means of a metal strip 3, and a rear portion 4 cut into the form of an annular ring member radially severed at one point and having its external periphery 5, its internal marginal edges 6, and the marginal edges 7 of the severed portion bound with sheet metal bi-folded over the ends of the wire composing the mesh, best shown at 8 in Fig. 5.

' over the hub of the fan,

radially inward thereby 1930. Serial No. 455,709.

The inner end 8a of the cylinder 1 isfitted with a triple folded metal facing 9, the outer fold 10 extending well beyond the two inner folds 11 and 12. The inner fold 10 is first curved radially outward and then radiallym inward so as to form a groove 13 adapted to' receive the external periphery 14 of the annular ringmember 4. The over-all diameter of the ring member 4 is slightly greater than the diameter of the cylindrical portion 1, the. groove 13 extending outwardly beyond the walls of the cylindrical portion 1, more clearly shown in Fig. 6. o

The inner marginal edge, as shown at 14, extends radially inward so that the annular. ring member could not beinserted, it being of greater diameter, without being divided as indicated in Fig. 3; therefore, the division serves two purposes, first, it is necessary for it to be divided in order that it may he slipped.

and second, in order that it can be contracted to less than its normal diameter, by causing the ends 15 and 16 of the annular member to overlap each other, in order to spring it into the groove 13. The ends 15 and 16 are then abutted against each other and bound in place by the flexible metal members 17 and 18, as shown in Fig. 4.

When the ends are thus bound together,.

the annular ring member fits snugly within the groove 13, best shown in Fig. 6, and is held in place by the overlapping edges of the grooved member 13. 7

Having fully described my invention, what.. I claim as new and useful and desire to pro tect by Letters Patent is:

A fan protector of the class described, comprising a cylindrical barrel of wire cloth, permanently closed at its outer end and hav gg, ing its inner end bound around with tri-fold ed metal, the outer fold of said tri-folded binding extending beyond the two other folds and curved first radially outward and then forming a circum-=.- 9o

ferential groove about the periphery of the inner end of said cylindrical barrel, an annular split ring member of Wire mesh cloth circumferentially bound with bifolded sheet metal, said split annular ring having an ex ternal diameter greater than the diameter of said barrel and less than the internal diameter of said inwardly turned outer fold of said metal binding, means for fastening the ends of said split annular ring member.

In Witness whereof I have hereunto affixed my signature this 17th day of April,

EMMA K. COOK.
