Description
Dec. 5,1939? w. KRAMER 2,182,591
TOY AIRPLANE Filed Feb. 4, 1939 INVENTOR ATTORNEY Patented Dec. 5, 1939 UNITED STATES PATENT OFFICE TOY AIRPLANE William Kramer, Richmond Hill, N. Application February 4, 1939, Serial No. 254,557
3 Claims.
This invention relates to mounting means for the propellers of toy airplanes, and my improvement consists in the provision of a novel form of bearing that is extremely simple and inexpensive, together with propeller and power band clamping means, adapted to co-act with said bearing, said clamping means being of simple, unitary construction, both said bearing and clamping means having a high degree of efliciency.
Briefly stated my new mounting means comprises an eyelet that has a hollow cylindrical portion and a flange, said eyelet being fitted to the front end of the airplane, and a smaller eyelet whose hollow cylindrical portion is rotatably entered within the first named or larger eyelet, said smaller eyelet having a shoulder to exert thrust bearing against the flange of the larger eyelet, and also having arms adapted to be clamped about the propeller. The power band is passed through the smaller eyelet and about the propeller, to which it is secured by the clamping arms of the smaller eyelet.
Other features and advantages of my invention will hereinafter appear.
In the drawing:
Figure 1 is a perspective elevation of a toy airplane equipped with my improved propeller mounting means.
Fig. 2 is a side sectional View, on the line 22 of Fig. 3, showing the nose portion of a fuselage with the power band as passed through the mounting means and clamped about the propeller.
Fig. 3 is a plan view in section of Fig. 2.
Fig. 4 is a plan view of the propeller clamping eyelet, and
Fig. 5 is a section on the line 5-5 of Fig. 4.
My improved propeller mounting means is here illustrated as used in conjunction with the nose of a hollow fuselage, which may be formed of moulded material, but obviously is not limited to such usage as it may be employed with other types of toy airplanes having different kinds of wing carrying elements.
As here shown there is a hollow fuselage or body member I, with wings 2, the fuselage having a nose cap 3 which is pierced to receive an eyelet A that consists of a tubular portion 4 and an annular flange 5, said flange lying against the outer surface of cap 3.
Also a propeller mount member B which consists of a tubular portion 6, smaller in diameter than tubular portion 4 is provided and adapted to flt rotatably therein, a shoulder portion 1 projecting radially from portion 6, to exert thrust pressure against flange 5. Arms 8, 9 are extended oppositely from shoulder 1, the arm 9 being longer than arm 8 for a purpose to be referred to hereinafter. I 5;
A usual form of power band, indicated at I 0, is engaged at one-end to anchorage means (not shown) in .the fuselage, and at its other end is passed through the tubular portion 6 and thence around the central portion I i of a propeller I2. 10 It will be observed that the arms 8, 9 are'laid against the opposite sides of propeller portion ll, over the band It, and that the longer arm 9 has been turned over and clamped against the outer surface of arm 8, as at 90,, thereby securely binding together the propeller, power band and mount member B, whereby, under the released power of a twisted elastic band the propeller will rotate with the mount member B, whose shoulder 'I will exert thrust against flange 5, and whose tubular portion 5 will spin in tubular bearing 4.
It should be noted that the fuselage or wing carrying body member I, while here shown as a hollow structure, with a nose cap 3, may have any other known form, and be provided with suitable means, other than the cap 3 for engagement by the eyelet A. This explanation is deemed necessary because the inventive features contained in this application comprise the said eyelet A- and the mount member B, and the nature of the engaging or supporting means for eyelet A may have other suitable structural character than that here illustrated.
Variations within the spirit and scope of my invention are equally comprehended by the foregoing disclosure.
I claim:
1. A toy airplane having a body member, an eyelet engaged with said body member, a propeller, a propeller mount having a tubular portion fitting rotatably in said eyelet, a power band passed through said tubular portion and about said propeller, and means extended from said mount that embrace said propeller and clamp said band thereto.
2. A toy airplane having a body member, an eyelet engaged with said body member, a propeller, a propeller mount having a tubular portion fitting rotatably in said eyelet, a power band passed through said tubular portion and about said propeller, a shoulder on said mount that forms a thrust bearing in co-action with said eyelet, and means extended fromsaid shoulder that embrace said propeller and clamp said band thereto. 5
3. A toy airplane having a body member, an eyelet adapted for engagement with the front of said body member, said eyelet having a tubular portion and a flange, a propeller, a mount for said propeller comprising a tubular portion adapted to fit rotatably in said eyelet tubular portion, a. shoulder on said mount adapted to co-act with the flange on said eyelet as a thrust bearing, arms extended from said shoulder to embrace said propeller, and a power band passed through the tubular portion of said mount and about said propeller, to be clamped thereto by 5 said embracing arms.
WILLIAM KRAMER.
