PLANE-FASTENER FOR Specification of Letters Patent.


Patented Apr. 18, 1916.

Application filed March 16, 1915. Serial No. 14,679.

To all whom M ay concern:

Be it known that I, HUGO ROSENSTEIN, a citizen of the United States. residing in the borough of'Broo-klyn, in the city and State of New York, have invented a new. and useful Plane-Fastener for Toy .and Model Aeroplanes, of which the following is a specification.

This invention relates to my and model aeroplanesand my improvements have particular reference to means whereby the aerofoil members may be conveniently and re movably attached to the frame, said means also enabling the adjustment of said aerofoil, members, in proper angular positions relatively to .said frame.

To theseerrds my invention consists of an attaching elevicc composed of hard drawn wire, shaped to enable it to fit over the frame bars of the model or toy and to tensionally receive an aerofoil member, which is thereby held in adjusted position.

For model or toy aeroplanes having a frame consisting of two diverging bars arranged as a V, and having a supporting aerofoil disposed toward the broader portion thereof. I employ engaging wires, one for each bar, bent in two places to provide sockets for-the bar. and having inturned, opposing, end hooks, to tensionally engage opposite edges of said aerofoil. and thus hold it in place upon the frame.

The forward aerofoil, which forms the elevator plane. is connected to the. narrow portion of the V frame by a bent wire having two opposed socket portions. to receive. respectively. the frame bars; the intermediate wire portion being bent to comprise a receiving socket, above the frame. for the rear edge of said elevator plane; and the free ends of said wire being crossed and bent to provide terminal socket, portions to tensionally engage with advance portions of the frame bars. T In a modified form of my invention. wherein the wire attaching devices are intended for use with a type of model or toy aeroplane having a single bar as a frame. the supporting aerofoil. in this instance, is connected to said bar by a wire which is doubled upon itself. forming a sockct at its closed end to engage beneath said bar, its arms crossing above said bar. there forming a receiving socket with the upper surface of said bar for the aerofoil, and its free ends formed into hooks which engage as sockets with said bar. In this modified device, the rear ntlir foil or elevator plane is attached to the.

frame bar by a wire which is folded upon A self. engaged at its closed end with a stud extending above the frame bar. and, formed into hook like sockets at its free ends. which engage beneath the frame bar. thus leaving an inclosed space above the frame bar to receive the acrofoil.

Other features and advantages of my said invention will be hereinafter referred to.

In the. drawings: Figure 1 is a perspective of a form of the device embodying: the in v vention. Fig. 2 is a top view of the same. Fig. 8 is a side elevation of the same. Fig. 4 is a front elevation of the same. Fig. 5 is a perspective of a second form of the device embodying the invention. 6 is a top view of the same. Fig. 7 is a side elevation of the same. Fig. 8 is a front elevationof the same. Fig. 9 is a perspective of a third form of the device embodying this invention.

Fig. 10 is a top view of the same. Fig. 11 is,

a side elevation of the same. Fig. 12 is a perspective of a fourth form of the device embodying the invention. Fig. 1.3 is top view of the same. Fig. 14 is a side elevation of the same.

In the. form of my invention which illustrated in Figs. 1 to 8 inclusive, wire fastening devices for the supporting and clevating aerofoils are shown, the frame bars A B being shown only in part, for'the purpose of indicating the relation between said devices. the frame members, and the aerofoils. Also diagrammatically the support ing aerofoil is shown in part at C and the elevator aerofoil at D. Y

The frame bars A, B, which are here shown as rectangular in cross section, may form together a V frame, as indicated in Fig, 1. p

The supporting aerofoil C is attached to each of the frame bars A, B, as by separate devices composed of pieces of spring wire each bent at a b to form separate rectangular sockets shown in Fig. 5, to receive, at different points, a bar of the frame, the

connecting portion 0 of said wire being bowed or bent upwardly, thus leaving a slight clearance between said wire and the upper surface of the bar, to receive an aerofoil stiffening rod (not shown). Said piece of wire, beyond the bent portions a and b respectively, is formed into inwardly directed hooks d e, to receive, respectively the front andhrear edges of the supportingaero' foil and thus to attach the latter to the foil D to the frame bars l to 4), is

bent inwardlyat f and g to receive the bars A, B, respectively, the intermediate wire portion being formed into a hook like cradle h, opening rearwardly to provide a receiving socket for the forward edge of aerofoil D, said cradle it being supported above the uppersurface of the frame, by the upstanding Wire portions 11 By this arrangement of the cradle h the aerofoi-l D is given a desired angle of incidence, enabling it -to serve as an elevator. Q f

Rearwardlyof the bends f and g, the free I arm kvl' of the wire are'crossed, beneath the fraine, said arms terminating in socket like hooks mn which, respectively, engage with theframe bars B, A, and have upturned lips m" n, to also receive the rear edge of t e foil D' I the modified form of toy or model aeroplane, for which the attaching devices shown in Fi s. 9.15014 are shown, a supportingaero oil, asE (see Fig. 9,) .is fitted between the upper surface of frame bar F andthe crossed, strands of a wire which is 'bent atoiand-there fitted over said bar-F,

its-free'ends having the socket 'likehooks which alsoenga e said bar, the interzmediate, crossed 'por ion of said-wire thus j lying above the upper surface of said bar band attaching the ae'rofoir'to the frame. 1
