AIRSHIP.

Patented Aug. 15, 1922.

Application filed April 25, 1921. Serial No. 464,097.

To all whom it may concern:

Be it known that CHARLES D. THOMP- sos, a citizen of the United States, residing at Kirksville, in the county of Adair and State of Missouri, has invented new and useful Improvements in Airships, of which the following is a specification.

This invention relates to airships, and he particular application to a machine wherein use is made of a pluralit of sustainin propellers mounted on vertically disposed shafts, and driving propellers carried by a horizontally disposed shaft.

One of the principal objects of the invention resides in equipping the machine with movable members pro ecting beyond the opposed ends of the machine. and susceptible of simultaneous vertical adjustments in opposite directions to assist in the raising or lowering of the machine, and also susceptible of horizontal adjustment for guiding the machine to the left or right, means being provided for controlling the movements of said members.

Another object of the invention resides in the provision of means for lifting the ground enga ing wheels and positioning the same wit in the body of the machine, and subsequently closing the openings through which the wheels pass, the means being further utilized for lowering the wheels to a position for use when landing.

In carrying out the invention, 1 make use of a motor for operating the driving propellers, and a separate motor for operatmg the sustaining propellers. a clutch mechanism being provided which allows the first mentioned motor to be coupled with the driving mechanism of the-sustaining propellers, in event the latter mentioned motor becomes disabled for any particular reason. I

' It is also In purpose to mount the sustaining propel lers upon frame-like members which are capable of being folded substantially in parallel relation at the op posed sides of the machine, or extended for use as the occasion re uires, means being provided whereby the frame-like members can be conveniently adjusted to occupy either of their positions.

The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in the combination, construction, and arrangement of parts as claimed.

In the drawings forming part of this application. like numerals of reference indicate similar parts in the several views and wherein:

Figure 15 is a sectional view taken on line 15 15 of Figure 14 looking in the direction the means for controlling the doors.

Referring to the drawings in detail, 10 indicates the body of the machine which includes a substantially arch-shaped top portion 11, beneath which is arranged a shaft 12 which carries the driving propellers 13 A semi-cylindrical member 14 is positioned between the shaft 12 and the body 10 of the machine to prevent air currents from being driven in the direction of the occu ants of.

the machine as willbe readily un erstood, the propellers 13 operating between the arch-shaped member 11 and the member 14 as clearly illustrated in Figures 3 and 4. The body 10 is provided with an entrance opening which is normally closed by a door 15 and is also equipped with windows 16. The shaft 12 is operated by a motor in a manner to be hereinafter more fully described. The arch-shaped member 11 is supported upon the frame of the machine which includes the spaced parallel members 17 illustrated in Figure 1, these members projecting an appreciable distance beyond the member 11 and having pivotally connected thereto the spaced parallel members 18 forming part of adjustable frames 19 arranged at the opposed sides of the machine. These frames also include planes 20 which project beyond the ends of the arch-shaped member 11, and which planes together with the frames 19 are susceptible of vertical swinging movement upon the parallel shafts 21 which constitutes pivots therefor. The manner in which these frames are adjusted will be hereinafter fully described. The spaced parallel members 18 of the frame support the vertically disposed shafts 22 upon which are mounted the horizontally disposed sustaining propellers 23.

Projecting from the opposite ends of the arch-shaped member 11 are what I term movable directing members. Each of these members are made p of two identically constructed

sections

24 and 25 respectively, the sections being shaped to unitedly define a semi-cylindrical member which in reality forms a continuity of the arch-shaped member 11. Each section is supported by a. rod 26. these rods being associated with the meeting edges of the

respective sections

24 and 25, and the corresponding extremities of these rods arranged adjacent the archshaped member 11 are offset and provided with teeth 27 which mesh with a pinion 23 journaled between the arch-shaped member 11. This construction provides for relative movement between the

sections

24 and 25 of each member, when the member is adjusted laterally to direct the machine to either the right or left, depending upon the particular direction ofmovement of the members. The members are simultaneously adjusted horizontally through the instrumentality of a hand wheel 29 which is carried by a stub shaft 30 upon which is fixed a pulley 31. An endless belt 32 is trained over this ulley and arelatively large pulley 33 fixe u on the shaft 34, the shafts being arranged lbngitudinally of the machine and supporting pulleys 35 at the opposed ends thereof. A cable 36 is provided for each pulley 35, and each cable is wound about its adjacent ulley as illustrated in Figure 9, the termina s of said cable being connected to the outer ed s of the

respective members

24 and 25 0 each member as indicated at 37 in Figures 1 and 9. Each of the cables 36 are similarly disposed. and. are trained over pulleys 38 in a manner so that when the shaft 34is rotated in one direction, the directing members will be shifted laterally to direct the machine to the right, and when the shaft 34 is rotated in an opposite direction, the directing members will be reversed to direct the machine to the left.

These directing members are {also susceptible of vertical adjustment for lifting or lowering the machine as will be readily un derstood. although the normal position of the members is illustrated in Figures 1 and 2. For adjusting the members vertically, I provide spaced pairs of stub shafts4Q which are arranged transversely of the machine adjacent the opposed ends thereof, and supported by yokes 40' which are carried by vertically disposed pivots 40 Fixed upon each shaft is a toothed wheel 41, and a pulley -12. This mountihg of the shafts 40 allows the directing members to be moved laterally as will be readily understoodf Depending from each

section

24 and 25 pf each directing member above referred to is a curved arm 13 which passes through an opening 44 in the body of the machine, each arm 43 terminating to provide a straight toothed portion 45 which meshes with the adjacent wheel 41. Trained over the pulleys 42 of the respective shafts 40 is a cable 46 which is also trained over idle pulleys 47. certain of the latter mentioned pulleys directing the cable over a pulley 18 fixed upon the shaft 49 which is rotated by means of the hand wheel 50. When the hand wheel 50 is retated in the direction indicated by the arrow in Figure 3. the cable 46 is moved in the direction indicated by the arrow in 51. rotating the shafts 40. which in turn rotates the toothed wheels *1. thereby effecting an adjustment of the curved arms -13 at the opposed ends of the machine, one set of these arms moving dovf nwardly as indicated by the arrow 52, while the other set of arms move upwardly asindicated by the arrow 54. Consequently, the directing members at the opposed ends of the machine are simultaneously adjust-ed vertically, but one of.

these members are moved upwardl while the other is moved downwardly. his adjustment may be reversed by turning the hand wheel 50 in the direction op osite to that indicated by the arrow 56 in igure 3, the adjustments of the directing members vertically controlling tha'mavements of the machine in an upward o1 downward direction. Supported by each

section

24 and 25 of each directing member is an angularshaped arm 57, the terminal of which is offset' and extended downwardly as at 58 through a slot in a bracket 59, This slot is indicated at 60 and limits the movements of the directing members laterally, friction between the arm 57 and the bracket 59 being minimized by use of rollers 61 carried by the offset extremity of the arm and arranged to engage the opposed sides of the bracket as clearly illustrated in Figure 18.

Hingedly mounted upon each

section

24 and 25 of each directing member is a wing 62, the hinged joint of this member being indicated at 63. These wings 62 are nor-. mally arranged horizontally, and closes the space between the directing members and the planes 20. The wihgs 62 are susceptible of vertical movement incident to the rise or fall of the machine as will be readily understood.

Arranged longitudinally of the machine are shafts 64 which are driven from an engine shaft 65 by means of endless belts 66, these belts being trained over suitable pulleys 67 carried by the engine shaft and over pulleys 68 fixed upon the shafts 64. Carried by a vertical shaft adjacent the shaft 64 is a beveled gear 69 which meshes with a similar gear '70 carried by the shafts 64. As clearly illustrated in Figure 6, there is one of these beveled gears 70 for each gear 69, and consequently when the shafts 64 are ro tated, the propellers 23 are operated by means of the cables 70' which are trained over pulleys 70" carried by the vertical shafts above referred to. and also over pulleys associated with the sustainingpropeh lers 23. The shaft 12 which carries the driving propellers 13 is also equipped with a pulley 71 over which is trained a belt 72, the latter being trained over a pulley 73 carried by an engine shaft as clearly illustrated in Figure 3., As clearly illustrated in both Figures 3 and 6. I employ a motor indicated at 74 and o crating the sustaining propellers 23, whi e the motor 75 is utilized for operating the shaft 12 which carries the driving propellers 13 Between the two mobelts 66 which operate the shafts 64. The

clutch collar 76 is operated by means of a rod 78, and can be quickly moved into engagement with the collar 77, to couple the pulleys 67 with the motor 75,'whereby the shaft 64 and the sustaining propellers may be operated by the motor 75 in an emergency, or in other words, in event that the motor 74 becomes disabled, and fails to operate. The clutch mechanism is also ro vided with sliding clutch engaging mem ers 79 which are mounted on the shaft of the engine 74, so that this particular motor can be operatively associated with the pulleys 67 or disconnected therefrom as the occasion requires. These clutch engaging members 79 are controlled by operating rods 80 and 81 respectively.

The pivoted frame-like members 19 which support the sustaining propellers are susceptible of being folded into parallel relation at the opposed sides of the machine clearly indicated by dotted lines in Figure 11, although the normal position of these members is illustrated by full lines in the same figure. For controlling the movements of the frame-like members 19, I make use of a plurality of cross heads 82, each of which slide vertically ina guide 83. There is one of these cross heads for each parallel element 18 of the frame-like members, the cross heads being associated with an arm 84 which 18 also connected with the bracket 85 which supports the adjacent propeller 23. A cable 86 is trained over pulleys 87 carried by a shaft 88 which is arranged in spaced parallel relation to the shafts 64, and these cables 86 are trained over idle pulleys 89, and have their terminals connected to the opposed ends 1 10 of the cross heads 82. Consequently. when the shaft 88 is rotated incident to the rota tion of the shaft 64, a pull is exerted upon the cross heads 82 in one or the other dircw tion, depending upon the particular direction, of rotation of the shafts ,88. so as to either lower the frame-like members 19 to their folded positions illustrated by dotted lines in Figure 11, or to extend the frames to their normal positions for use. For con trolling the direction of rotation of the shafts 85. l provide a reverse gear mechanism indicated at 90 in Figure 6 which is controlled by means of a manually operated lever 91, the shafts H8 being rotated in uuison by reason of the endless belt connection 92 which associates the corrcs 'mnding ends of the shaft as illustrated in Figure 6. this belt being trained over pulleys 93 supported by the shafts 88 for this purpose. The ca -bles 86 are trained over idle alloys 94 and then extended across the bottom of the ma chine and over the pulleys 100 carried by the shaft 96. The cables 98 are arranged adjacent the ends of the machine and are divergently disposed, these cables passing through openings in the machine in the same manner as the cables 97, and trained over pulleys 101 carried by the shaft 96. When the frame-like members are lowered to thei folded positions the slack in the cablesf97 and 9 8 are taken up to prevent these cables from becoming entangled in the adjacent parts of the machine. q

The machine is equipped with ground Wheels, the front pair of which are indicated at 102 and the pair at the rear of the machine indicated at 103. The wheels are jour naled in bearings provided by the spaced arallel members 104,. and each bearing is ormed to provide a hook-like portion 105 which retains the wheels in position for use when landing. Rising from each parallel member 104 is a standard 106 which is spaced from thehook-like member 105 to permit the wheels in their entirety to be moved upwardly within the body of the machine through openings 107 which are rovided in the base of the machineas il lustratedin Figure 15. Arranged at the opposite sides of each wheel are cables.108, the terminals of which are secured to the-standards 107 as at 109, the cables being trained over ulleys 110 supported by the axleof the whee and thence over a pulley 111 journaled at the upper ends of the standards106.

These cables extend upwardly to the cente of the machine and are coiled about drums 1.12 carried by the shaft 113 in a manner to wind and unwind so as to elevate the wheels to the dotted line osition illustrated in Figure 5 when the shaft 113 is rotated in one direction. When rotating in an opposite direction, the cables unwind from their respective drums and allow the wheels to project throu h the openings 107, in a position for use. Tghe shaft 113 supports a pulley 114 over which and a pulley 115 is trained an endless belt 116, whereby the shaft 113 is rotated u on rotation of the shaft supporting the pul e r 115, which shaft is equipped with a hand wheel 117.

When the wheels are elevated to the position illustrated by dotted lines in Figure 15, the openings 107 through which wheels pass are closed by sliding doors 118, these doors sliding transversely of the machine in suitable guides 119. Each door is connected to cables 120 arranged at the opposed and unwound from the drums to permit the drum to be moved to an open position. The drums 121 are carried by the ends of a shaft 122, one'end of each shaft supporting a beveled gear 123 which meshes with a similar gear 124 supported by a shaft arranged at a, right-angle to the shaft 122, and which shaft is indicated at 125. One of these shafts 125 is rotated through the instrumentalit of a hand wheel 126, while each of the sha ts 125 support pulleys 127 about which is trained an endless belt 128- the runs which are crossed as illustrated in Figure 19, so that when the hand wheel126 is retated, in either one or the other direction, the doors 118 at the opposed ends of the machine are simultaneously'closed or o ened. The cables 120 are trained over suitab e pul? leys 128.

Arran ed beneath and parallel to the enine shaft, is a shaft 129 which is journaled .lIl suitable bearings 130, and the shaft 129 is equipped with a pulley 131 over which and the pulley 132 associated with the engine shaft, is trained an endless belt 133, whereby said shaft 129 is rotated from the motor of the machine. The shaft 129 supports a beveled gear 134 which meshes with a similar gear 135 carried by a transversely disposed shaft 136 to rotate the latter mentioned shaft for the purpose of driving the rear traction wheels 103. Each of the latter mentioned wheels is equipped witha Connecting the annuli of the whee s vided with teeth 144, the latter meshing,

with the adjacent pinions 145. Interposed between the pinions 145 and meshing therewith is an additional pinion 146, so that when the steering wheel 147 is rotated in either direction, the .annuli 139 are turned within their guides 140 thereby shifting the front wheels 102 to steer the machine.

While it is believed that from the foregoing description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the sec e of what is claimed.

hat I claim is: v
