ATTORNEY HOWARD J. SMILEY, OF CANTON, OHIO.

LAUNCHING AND LANDING DEVICE.

Specification of Letters Patent. Patented Aug. 14;*1917,

Application filed February 29, 1916. Serial No. 81,241.

To all whom t may concern.'

Be it known that I, HOWARD J'. SMILEY, a citizen of the United States, residing at Canton, in the county of `Stark and State of Ohio, have invented certain new and useful Improvements in Launching and Landing Devices,l of-which the following is a `the preferred embodiment of my invention,

Figure 1 is a front elevation of a device constructed inY accordance with the inven' tion;

Fig. 2 is a transverse section on the line 2 2 o f Fig. 1

Fig. 3 is a detail perspective of one of the sliding blocks;

Fig. 4 is a fragmentary detail perspective of one of the wheel supporting shafts.

Referring to the drawings by numerals, 1 designates the side bars ofD a suitable frame structure which may be either a portion of the flying machine structure proper or may be a portion of an independent frame for f attachment to the flying machine structure.

At any rate, a plurality of bars 1 are provided whichy are arranged in spaced parallel relationA and are connected by braces 2.

4Arranged below the frame vbars 1 and intermediate the same are a plurality of longitudinally spaced alined bars 3 and 5 which are connected and supported by the frame bars 1 by means of braces 4. A single relatively elongated bar 3 is provided intermediate the relatively short end bars 5, a space of any suitable width being provlded be- -tween theV bars 3 and 5, as is illustrated to advantage in Fig. 1 of the drawings, and

the bars are arranged in alinement, as'

shown. y

Above the spaces between the bars 3 and 5 and arranged in horizontal alinement parallel with the bars 3 and 5 are cross-bars 6 of a length to extend slightly over the adjacent inner ends of the bars 3 and 5. Verti-` cally arranged rods 7 have their upper ends journaled in the bars 6 and their lower ends secured rigidly in any suitable manner to the bars 3 and 5, thereby providing increased strengthening means for the device.

Rectangularly shaped blocks 8 are provided which have formed therein openings 9 of'a size to receive the ends of shafts 10 upon which the supporting elements, herein shown as wheels 11 are freely rotatable. The shafts 10 are provided adjacent their endswith transverse openings 12 which are adapted to aline with openings 13 in the blocks 8 which extend at right angles to the openings 9, when the shafts are arranged Within the openings 9, as is illustrated in Fig. 1 of the drawings. The alined openings 12 and 13 of the shafts and blocks respectively are adapted to receive the -.ve1- tical rods 7 so that the shafts 10 are vertically movable ulpon the rods, and at the same time are loc ed against removal from the blocks and held against rotation.

Expansively acting helical springs 14 are coiled about the r`ds 7 and have one end abutting the bars 6 and the other end abutting the blocks 8 exerting a tension to normally hold the blocks in engagement with the bars 3 and 5. y

Suitable brackets or .bearings 15 are secured to and depend from the bars', and

. these brackets have journaled therebetween concaved rollers 16 which are mounted for free rotation, the rollers being disposed directly above the wheels 11, as is shown.

Upon landing of a flying machine equipped with a device as just described, the wheels 11 engaging with the ground, and the weight of the machine bearing upon the frame will causethe blocks 8 together with the shafts l0 and wheels 11 to be moved upwardly upon the rod 7 against the action of thei yieldable springs 14, the springs serving to take up the shock which would otherwise occur, as will be understood. When the machine strikes the ground with great force it will be apparent that rings of a tension to take up shocks and Jars under ordinary conditions and to be most efcient under all ordinary conditions, would be of insufficient strengthhto entirely take up all lshocirsfin such an instances.;.lllhpreforertheprovision of the rollers' 16 prvidtop means to be with the ground.

l derstood and while described onespecific embodiment of my inlcomprising a frame, `porting elements revoluble on their own axes engaged by the wheels in such cases, and by making these rollers rotatable Jfriction is avoided between the wheels and the frame as the same are rotated upon engagement From the foregoing description taken in connection with the accompanying drawings it is thought thatthc construction and operation o-the yimproved shock absorbing device for ying machine will be clearly un- I have herein shown and to be limited except the claims may imvention l do not wish for. such limitations as port.

1. A Vdevice oi' the character described vertically movable supcarried by said trame, and rotatable means on thc frame to directly engage the supporting elements and limit their vertical movement but permit rotation thereof.

2. A device of the character described, comprising a frame, supporting elements including ground wheels carried thereby, said supporting elements being bodily movable in a fixed plane, mounted on said frame to directly engage the periphery of the wheels of said supporting element and limit movement thereof beyond a pre-determined point in. one direction in such fixed plane. y `3. A device of the character described comprising in combination with the frame structure 'of a flying machine, rods carried thereby, Asupporting elements including ground wheels carried by and longitudinally .rm'oiv'able upon said rods, resilient means engaging said supporting elements and tending to force them to their limit of movement in one direction, means to limit any such .movement'of the supporting elements upon Copies ci this patent may be ohtaine for ily movement in one thereby,

said rods, and means directly engaging the ground wheels at .their limit of movement in the opposite direction,

4. A4 device of the character described comprising a frame, supporting elements including ground wheels carried by said frame, said supporting elements being bodmovable in a fixed "plane and rolling abutments journaled in said plane to engage the peripheries of the wheels and limit their direction in said plane beyond a pre-determined point. V

5. A device of the character described comprising, in combination with the frame structure of a lying machine, rods carried blocks, shafts extending through said shafts being provided with transverse openings,' said blocks having openings formed therein, said rods being adapted to extend through the alined openings in the shafts and blocks, and supporting elements loosely mounted on 'said shafts.v

6. A device of the character described comprising a frame, rods carried thereby, supporting elements yieldably mounted upon said rods, and rollers carried by said frame to be engaged by the supporting elements.

7 A. device of the character described comprising, in combination with the 'frame structure oit a flying machine, vertically disposed rods rigidly carried thereby, blocks slidably: mounted upon said rods, shafts journalediin said blocks, Wheels loose on said shafts, expansively acting springs carried by said rods and engaging said blocksand rollers carried by the frame.

said blocks,
