This invention relates to stabilizing means for aeroplanes, the general object of the invention being to provide a weight which is supported on a rod which depends from the fuselage, the weight acting to prevent the aeroplane from nose diving, tail spinning and side slipping, as the weight will hold the craft on an even keel even though the wings or ailerons are damaged. The weight also acts to hold the craft firm and steady when headed into a strong wind and thereby gives the engine more power to drive the craftthrough the wind. The weight also acts to prevent the craft from deviating from its natural course, thereby rendering the craft easier to control, which will be a special advantage to those just learning to fly.

Another object of the invention is to provide means for raising the weight, so that it will be out of the way when the craft is to land.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which: K

Figure 1 is a side view of an aeroplane equipped with this invention, this view also showing the craft in dotted lines in a tilted position to show how the weight acts to bring the craft back to a horizontalposition. 40 Figure 2 is a plan view with parts broken away. 7

Figure 3 is a front view showing the craft in a horizontal position in full lines and in a tilted position in dotted lines. Figure 4 is a View of the means for raising and lowering the weight. I

Figure 5 is a detail view showing the collar on the weight rod to which the lifting and lowering cables are connected' As shown in these views, a vertically arranged guiding tube 1 passes through the fuselage and forms guiding means for a rod 2 which has a weight 8 connected with its lower end. An appreciable distance above the weight, the rod is formed with an en-, largem'ent 4 and a collar 5 is slid ably arranged on the rod and has its upper end bearing against the enlargement. Cables 6 connect the collarwith parts of the fuselage and with parts of the wings so that these cables and the collar act as supporting means for the rod and the weight.

A pair of cables 7 have their lower ends connected with the weight and these cables pass upwardly through the bottom of them; fuselage into the cockpit of the same where they are connected with the drums 8 arranged on a shaft 9 which is rotatably supported in the cockpit. The drums are spaced apart and a hand wheel 10 is fastened to the shaft between the drums, whereby the shaft can be turned to wind and unwind the cables on the drums. One of the drums is provided with the ratchet means 11 for preventing retrograde movement of the parts.

From the foregoing it will be seen that the weight is suspended a considerable distance below the craft so that it will act as stabilizing means for the craft as the weight acts to prevent endwiseand sidewise tilting of the craft. The weight tends to hold the craft on an even keel, even when headed into a strong wind, so that the engine will have more power and the craft can be more easily controlled. '85

When iti's desired to land the craft, the. shaft to which the drums are attached is rotated by the hand wheel so as tocause the cables 7 to raise the weight and its rod to 1 a position where the weight will be above '90 the landing wheels. After the craft takes off again, the dog of the ratchet means is moved to releasing position so that the weight will drop to its operative position.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

4 It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, v

provided that such changes fall within the scope of the appended claim.

What I claim is 'In an aeroplane, a vertically arranged tube passing through the fuselage and the wing, a rod having its upper part slidably arranged in said tube, a weight onthe lower end of the rod, a stationary collar on the rod an appreciable distance from the lower end thereof, a sliding collar on the rod be low the first collar, cables connecting the sliding collar with parts of the fuselage and wing of the plane, a shaft'journaled inthe fuselage, a pair of drums connected With the shaft, cables connecting the drums with the Weight, a hand heel on the shaft whereby the same can be rotated to Wind the cables on the drums and ratchet 1neans associated with one drum for preventing retrograde movem ent of the drums and permitting the I cables to unwmd from the drums when the V ratchet means are disengaged.
