Claims.

This invention relates to a hand control means for model airplanes, and has for an object to provide such a device which is a combination reel, on whichmay be wound flexible wires or control leads to a plane when not in use, and a control handle which may be gripped and held in the hand of the operator when the leads are connected to the controls in the plane, whereby these controls may be operated.

Another object is to provide a combined device of this character in which the leads may be either wound on the device for storage when not in use, or unwound and connected to controls on the plane, without disconnecting them from the device, and then the device used for manipulating these controls.

Another object is to provide a device of this character which may be easily manipulated for winding and storing the flexible leads for the controls when not in use, or for manipulating them when connected to the plane, without requiring the necessity of disconnecting the leads or transferring them from one element to another, such as from a storage means to a control means.

With the foregoing and other objects in view, I have devised the construction illustrated in the accompanying drawing forming a part of this specification. It is, however, to be understood the invention is not limited to the specific details of construction and arrangement shown, but may embody various changes and modifications within the scope of the invention.

In this drawing:

Fig. 1 is a perspective view showing how the device may be used as a hand control means for manipulating the controls of a model airplane;

Fig. 2 is a side view of the device showing the lead wires wound thereon and not connected with the plane;

Fig. 3 is a top plan view looking from the right of Fig. 2; and V Fig. 4 is a diagrammatic view showing an arrangement of control levers which may be used for the plane.

Referring to the figures of the drawing, a

model airplane of any suitable type is indicated at It operated by a suitable type of. miniature engine I! and provided with hinged elevator controls l2 controlling the altitude of the plane in flight. These may be manipulated and controlled by any suitable means, such, for example, as 'a lever I3 connected by the leads M to a pivoted lever i5. This lever may be ma- 2 nipulated by means of another lever I6 connected by flexible leads, such as fine piano Wire to a control means I 8 held by an operator on the ground, the control being arranged so that the elevators I2 may be swung up and down about pivotal mountings at their forward edges for controlling up and down movement of the plane, in a manner well known. Leads I! also keep the plane in a circular path of flight.

The improved control device I8 comprises a body member I9, preferably of a substantially fiat circular or disc-like shape, provided with a peripheral groove 20 in which the flexible leads I! may be wound when not in use, as shown at l1a. The body member may be of any suitable material, such as wood, molded plastic, or other suitable material. It is mounted by any suitable means, such as the pivot screw 2|, on a handle 22 at one side of the device, the body turning either directly on the screw or prefer ably with a simple bushing 23 forming a hear: ing, and also preferably with washers 24 on op posite sides thereof. 0n the other side of the body is a suitable crank handle or grip 25 by which the body may be rotated on its pivot 2| for winding up the flexible'leads I1 and controlling the unwinding thereof. It will be seen that there are two of these flexible wires or leads I! arranged when in use to control the flight of the model plane to ex tend to the plane from opposite sides of the body member l9 and they may be connected to this body at any suitable point or points to secure this arrangement. It is preferred to connect them to the body at their inner ends at spaced points at substantially diametrically opposite sides of the pivot 2|, and in the arrangement shown the body member is provided with a slot 26 at the bottom of the peripheral groove 20 on diametrically opposite sides of the body with a cross pin 2! to which theends of these con--v trol leads or wires" are connected, as shown at 28. is connected to any suitable type of swivel loop or hook 29 by which it may be easily connected to or disconnected from one of the loops 30 of short leads from the airplane control.

At the lower side of the body and between the leads I! as they extend from the body to the plane, the body is provided with an oblong opening 3| through it shaped to form a hand grip through which the fingers of the operator may be extended, as shown in Fig. 1, the outer side preferably being curved, as shown at 32, to form a comfortable and effective grip with the rim At their opposite or free ends each wire.

portion 33. It will be seen that when the flexible wires or the leads I! are unwound from the reel or body member and extend from opposite sides thereof and are connected to the control on the airplane, this hand grip is between these leads, and therefore by rocking the body member back and forth in the plane of this member the leads may be moved back and forth toward and from the plane to manipulate the plane controls I2 to vary its altitude and control its flight.

After the flight of the plane, the swivel connections 29 may be disconnected from the plane. controls, and then by holding the handle '22 in' one hand the reel or body member I9 may be rotated by means of the crank handle 25 to easily and quickly wind the wires on the body in the groove 20. When it is again desired to use the device in controlling the plane, they may be as easily unwound and connected to the airplane control. llt is therefore not necessary to disconnect the wires from the reel and connect them to a separate hand or control grip, and this ,device itself operates both as a reel for the wires and as an operating hand grip for operating these wires to control the plane. The operator merely unwinds the Wires and connects them to the plane and then manipulates the device itself to control the-plane, and when through operating the plane merely winds up the wires again on this device. The wires are permanently attached to the reel so that the reel acts bothas a storage medium and also the operating means. The wires do not become tan led in transferring them from one element to another, as in the common type of control.

If desired-the portion of the-body l9 opposite the hand grip opening *may be provided with openings 34 to lighten the'weight of the body and also to improve the balance.

Having thus set forth the nature of my invention, I claim:
