FAN ATTACHMENT.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed December 23, 1914. Serial No. 878,720.

To all whom it may concern:

Be it known that I, CHARLES R. MILTEN- BERGER, a citizen of the United States, residing at Albia, in the county of Monroe and State of Iowa, have invented certain new and useful Improvements in Fan Attachments, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in fan attachments and has relation more particularly to a device of this general character especially designed and adapted for use in connection with a rotatable element included in household machinery, such as washing machines or the like; and an object of the invention is to provide an attachment of this kind which may be applied in operative position with convenience and facility and which will operate with a maximum of efficiency.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved fan attachment whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

The novel features of the invention will be carefully defined in the appended claims.

In order that my invention may be the better understood, I will now proceeed to describe the same with reference to the 'accompanying drawings, wherein Figure 1 is a front elevational view of a fan attachment constructed in accordance with an embodiment of my invention, the rotatable element to which it is shown applied being indicated by dotted lines; and Fig. 2 is a view,partly in end elevation and partly in section, of the device as herein embodied, the coacting rotatable element being indicated by full lines.

As disclosed in the accompanying drawings, B denotes a body mounted for rotary movement and which may be comprised in a machine of any desired character but preferably a machine intended for household purposes, such as a washing machine.

As herein embodied, my improved attachment comprises a casting or hub 1, herein disclosed as circular in form and having produced adjacent its periphery the laterally disposed equidistantly spaced lugs 2 to each of which is adapted to be suitably secured, as indicated at 3, the angular tail 4: of a fan blade 5. Each of the fan blades is set forth as disposed on substantially a true screw.

The outer extremity of each of the blades 5 has suitably secured thereto and disposed transversely thereof a rigid member 6 which serves to maintain the requisite pitch of the blade, and one extremity of said member projects beyond a longitudinal marginal portion of the blade and such projected portion 7 is adapted to be disposed through the body B whereby a convenient and eflective medium is afiorded for securing the attachment to the rotatable element with which it is adapted to coact. As herein embodied, the portion 7 is screw-threaded and adapted to be engaged by a conventional nut or bur 8. The portion 7 at a point immediately adjacent the marginal portion of the blade 5 but to one side thereof is provided with the shoulder 9 which is adapted to coact with the nut or bur 8 in order to assure the requisite connection with the body B, as is believed to be self-evident.

From the foregoing description, it is thought to be obvious that a fan attachment constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I claim:

1. A fan attachment comprising a hub, blades radiating therefrom, and transverse members carried by the outer extremities of the blades and projecting beyond a longicuring means for the attachment carried by tudinal margin thereof, said projecting porthe outer extremities of the blades. 10 tions of the members affording a securing In testimony whereof I hereunto aflix my means. signature in the presenceof tWo witnesses.

2. A fan attachment comprising a hub CHARLES R. MILTENBERGER. provided With laterally disposed lugs, fan Witnesses: blades provided with angularly disposed ROY T. ALFORD, tails in engagement With the lugs, and se- JOHN KEEFE.
