UNITED STATES HUGO JUNKERS, or DESSAU, Guarani AUXILIARY ROLLING DEVICE non NAVAL- mine mcnmns.
Application filed March 17, um. SeriallidffiEItJflfif.
To all whom it may concem:
Be it known that I, HUGO JUNKI 1RS, professor, a citizen of Germany, residing at Dessau, Anhalt, Germany, Coethenerstr. 27, have invented certain new and useful Improvements in Auxiliary Rolling Devices for Naval Flying Machines, for which I have made an application in Germany February 2, 1923, and of which the following is a specification.
' For drawing naval flying machines out of the water, boat carriages are used, which have a plate form or a frame fitting to the boat and are put in submerged state below the floats or the boat for being drawn on land entire with the machine. For this purpose below the' floats or the boat the water must be so deep as to allow the carriage to be submerged below them. If the strand is very flat, the flying machine must for the said purpose remain far from the land and is in danger of being swept away by wind or stream, the motor being at rest. In flying machines having two floats, a further difliculty arises, viz, the twocarriages,
needed for the two floats, can not easily be' fastened to the floats in precisely the same positions. Finally for lifting the flylng .machine from the carriage, if the same is to be available for further use, a crane or hoists must be provided on land.
For flying machines with floats it has been proposed to put on the floats wheeled frames, which are floating and may rigidly be fastened at the floats. In this case at least two such wheeled frames are needed for every float. In the water the fastening device needs a certain depth of water below the floats or the boat of the swimming machine, whilst also on land special devices must be provided for attaching or removing the wheel frames.
The invention consists in an auxiliary rolling device for naval flying machines,
which can easily be applied to the floating machine in a short time, in shallow or deep water and gives the possibility of rolling the machine out of the water and also on land, and which not only spares every hoist but in turn is able to serve as a holst for fixing or removing the floats or for transforming the machine into a land flying machine.
This is attained by constructing the auxiliary rolling device as a'strut. work with wheels, adapted to be fastened to the main structure of ingmachine, the struts preferabl beingjpivoted on the one or more wheel ax es ofjthe device, and adjustable in length. For bein able to be used in deep water without anger of .being submerged the device is preferably constructed so as to be floating or provided with floats of such arrangement, that it may easily be handledfrom the flying machine floats or the flying boat.
In the drawing of the invention are shown. Fig. 1 is afront view of the auxiliary rolling device in service position,
Fig. 2 is a side view of the same device, seen from the middle between the floats,
Fig. 3 is a front view of an auxiliary rolling device for a fl ing boat.
According to Figs. 1 and 2 the flying machine has two floats 1, which are fastened to the body or wing by struts 2 and stifftwo constructional forms ened between each other by horizontal j struts 3. -The auxiliary rolling device comprises an axle a with two'wheels 5, and at the said axle two pairs of main struts 6, 7 are pivoted so as to be swingable around this axle. These struts 6, 6, 7, 7 are fastened in the shown example to four points of the flying machine body by connections which can easily be loosened and fastened. These connections may be used simultaneously for fastening a landing wheel frame in case the strut 9, and diagonal cross cables 10 are interposed and fastened by tension devices 11 and connecting pieces 12, which can easily be loosened; these cables are fastened in or near the points, in which the main struts 7 are connected to the body and-secure the lateral rigidity of the whole device. For making the device unsinkable every main strut 6 or 7 is fitted with a float Cushions 14: are provided on the ends of the axle 4 for protecting the floats against being damaged by the device.
The new device is applied in the following manner: On a flat strand the flying machine goes by own force so near to the shore,
sleeve 8 the struts are then lengt that its floats catch the ground. The rolling device, folded to a flat shape by :virtue of the pivots of the main struts 6, 7, is then brought into the water and between the floats; this may easily be performed from the floats, the motor being kept running. The mainstruts 6,7 andg 'diagonal cableslO are passed below the horizontal struts 3 of the floats and fastened at the connecting points of the body.- By rotatin the screw llened until the floats are lifted from the ground, and the machine rests on the wheels. Thediagonal cables 10 are set under tension for securing the laterial rigidity of the device; this may be reached exclusively by aid of the screw sleeves 8, the tension devices 11 being previously adjusted to such a constant length, which corresponds to that length of the main struts 6, 7, which effects the lifting of the floats from the ground. Hereafter the machine may be rolled onto the strand, eventually by its own motor force, and may move on land as a land flying machine, if its tailis supported by a spur orother adapted device. In deep water the whole process is the same, as the whole device is adapted to float; by rotating the screw sleeves 8 the cables 10 are set under tension and the wheels 5 are then in right rolling position. i
On the shore the flying machine may be set down on the floats by simply loosening the screw sleeves 8, and the device becomes then free for further use.
. The device may in like manner be used as a hoist, for attaching or taking away or exchangin the floats or a carriage, without the use 0 any additional hoisting apparatus.
Fig. 3 shows in connection with a flying boat the new device consisting of two parts, each of which comprises a short axle 15 with a Wheel 16 and with pivotally attached struts 17, 18. These struts are fitted with.
the longitudinal rigidity is obtained either by a similar triangular strut work, arranged lengthwise, or by tension cables, which may be set under tension, in the same manner as in the first'example, by aid of the screw sleeves 19.
The handling of this device in deep or shallow water corresponds completely to that of the first described device.
What I claim is: we 1. An auxiliary rolling device for naval flying machines comprising a strut work,

Y
