Application May 4, 1954, Serial No. 428,426

3 Claims. (Cl. 244155) The present invention relates to kites and is more particularly directed to a mounting for propellers upon various types of kites.

The principal object of the present invention is to provide a mounting for propellers which can be affixed to various forms of kites without requiring additional parts, tools, or other special skill.

A further and important object of the invention is to provide a propeller for kites which when mounted thereon enables the kites to be flown without requiring a strong wind and generally under such weather conditions that known kites could not be flown.

A still further object of the invention is to provide a propeller for being mounted upon kites for aiding in the guiding and controlling of the course of the kite while in flight and which propeller creates a buzzing noise together with the appearance of an airplane propeller in flight. I

Further and important objects of the invention will be in part pointed out and in part obvious from the following description of the accompanying drawings, wherein:

Referring now more particularly to the accompanying drawings, wherein like and corresponding parts are indicated by similar reference characters, numeral 1 refers to the upright bar to whichis afiixed cross piece 2 at point 3 of a conventional kite.

Numeral 4 refers to an annular back mounting member having a flat inner face 5 which has a recess 6 extending diametrically thereacross which is large enough to receive one of said

kite frame members

1 or 2. A bulged portion extends upon the outer face of said mounting and recess 6 has a further recess 9 in communication therewith extending into said bulged portion. Further, said mounting has a plurality of openings 8 extending therethrough from the outer to the inner face thereof.

A front annular mounting member 10 has a flat inner face 11 with a recess 12 extending diametrically thereacross. A further recess 13 is in communication with said recess 12. Said front member has an outwardly tapering bearing portion 14 upon the front face thereof which has a flat top 15 and a bore 16 extending therethrough in communication with, but of a smaller diameter than recess 13. Said front mounting is substantially the same size diametrically as said rear housing and has openings 17 provided therethrough which are positioned to coincide with the openings 8 of said rear mounting member when said members are in several different relative positions.

A propeller hub 20 of substantially the same diameter as face 15 of member 10 has a bore 21 therethrough for coinciding with bore 16. A pair of

blades

22 and 23 extend diametrically opposite to one another from said hub and are of a configuration for being driven by air passing thereby. Said

blades having openings

24 and 25 respectively formed therethrough for creating a buzzing sound due to the passage of air therethrough upon the rotation of said propeller.

Said mountings are aflixed to

cross pieces

1 and 2 of the conventional kite by positioning face 5 of the rear mounting 4 as shown in Fig. 12 and the inner face 11 of the front mounting 10 as shown in Fig. 12A. Bar 1 is placed in recess 6 or 12 and bar 2 in the other of these recesses. The mountings are brought together as indicated in Fig. 128 each on an opposite side of the

cross pieces

1 and 2 and large head fastening pins 29 pass through the coinciding

openings

8 and 17 whereupon their free ends are bent as indicated for retaining the mountings to the cross piece.

Before so aifixing front mounting 10, propeller shaft 25 is extending through bore 16 with head 26 positioned in recess 13. Propeller hub bore 21 has said shaft 25 extending therethrough whereupon a tube 28 is likewise slid over the propeller shaft and the end of said shaft 27 bent forming an eye 27 to which can be afiixed the cord 33 for controlling the kite.

Thus, by pulling on cord 33 and facing the kite into the wind, the kite will begin to ascend with propeller 22 rotating and it has been determined that with the pro peller so mounted thereon, the kite will fly when very little wind is blowing and even when a kite without such a propeller could not be flown. Also the propeller permits the flyer of the kite, by manipulating the cord 33 attached thereto, to better control and guide the course of the kite while in flight.

As shown in Fig. 16 and more in detail in Figs. 17 to 21 inclusive, the present propeller mounting can equally as well be mounted upon other types of kites, as for example, a box kite where it is necessary to connect the mounting to one bar of the kite frame. For example, a box kite whose frame consists of elongated bars 31 with paper sheathing 30 extending around the top and similar sheathing 32 around the bottom, the present propeller mounting can be retained on one of said bars or uprights 31 by positioning both the front and back mounting

members

4 and 10 respectively with their recesses 6 and 12 extending parallel for coinciding when inner face 5 is placed against face 11, as indicated in Figs. 12C, 12D and 12E. The mounting members are then in the position shown in the exploded view of Fig. 17. Recess 6 can then receive the rear portion of upright 31 and recess 12 the front portion whereupon the large head pins 29 can be positioned through coinciding

openings

8 and 17 retaining the mounting members together and against upright 31 positioned therebetween.

As previously described for use upon a conventional kite, a kite string 33 afiixed to eye 27 can be used for pulling the box kite and causing the same to ascend through the aid of the propeller 22.

Openings

8 and 17 of the mounting members are positioned for coinciding when the inner faces 5 and 11 i are placed together and the grooves 6 and 12 are in alignment or substantially at right angles to one another. Thus, by turning either mounting member, said recesses can be positioned for receiving

cross pieces

1 and 2 or an upright 31 whereby the mounting can be affixed to these various types of kites. While four such openings have been shown, it is to be appreciated that more or less such openings can be provided for the present purpose.

Whereas in the present drawing the propeller mounting is shown attached to a side frame member of the box kite, it is to be appreciated that it may equally as well be attached to the top or other locations on the kite.

Also the

cross pieces

1 and 2 of the kite, shown in Fig. 1 can be of plastic and moulded with the mounting members as one piece if so desired.

The present invention is capable of considerable modification and such changes thereto as come within the scope of the appended claims is deemed to be a part of the invention.

We claim:

1. A structure comprising a pair of disc shaped members having flat inner opposing faces, said members each having a straight recess extending diametrically across its inner face with each recess capable of receiving a portion of a kite frame therethrough, one of said members having a hub extending from its outer face and a bore extending from its inner face through said hub, a shaft extending through said member bore and having a kite string connecting portion, a propeller rotatably mounted on said shaft, kite frame portions positioned in said recesses, and means for connecting said members together whereby said members are attached to said kite frame portion.
