DETACHABLE JOY STICK FOR AEROPLANES Filed Oct. 8. 1928 I 10 E l9 g I i; I I 5 n l art widow Patented May 26, 1931 unrren ,srATEs 7 CHARLES FRANKLIN SEATON, OF ELYRIA, OHIO DETACHABLE JoY s'rIoxFon AEROPLANES.
Application filed October 8, 1928. Serial No. 311,019.
This invention relates to a detachable joy stick for aeroplanes especially adapted to be used in connection witha dual control, whereby an instructor or'pilot can throw out of operation the joystick of his pupil-so that in case the pupil becomes frightened or in-' capable of controlling the machine, the instructor can detach the joy stick of the pupil in order to allow him to control the aeroplane.
Another object of my invention is to provide a joy stick which is so constructed that it can fit the general construction of connection now in use so that the same can be substituted for the pupils joy stick in an ordinary instructing plane, whereby the pilot or instructor can disconnect the joy stick of the pupil at any time so as to obtain control of the aeroplane.
Another object of my invention is to provide a joy stick which is exceedingly simple and cheap in construction and one in which the sections are so connected that a rigid stick is formed when in interlocked position and one in which the upper or handle section can be readily detached from the lower section by merely pulling on a cable.
Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined in the appended claims.
In the drawings,
Figure 1 is an elevation of my improved construction of joy stick;
Figure 2 is a detail elevation taken at right angles to that of Figure 1;
Figure 3 is a detail View partly in section showing the upper orhandle section of the joy stick detached from the lower section; and
for the purpose hereinafter fully described The reduced portion 3 at its upper end is Figure 4 is a section taken on line 1-4 provided with a threaded stem 5 on which is screwed a nut 6 forming a stop for the purpose hereinafter fully described. 1 Slidably mounted on the reducedportion of thetubular member 3 is a collar 7 which .55 has an internal flange 8 which is adapted to engage the nut 6 for limiting the upward movement thereof, the downward movement being limited by the member 4. The collar 7 is provided with oppositely disposed spaced to apertured lugs 9 and 10 in which are mounted pivoted dogs 11 and'12 provided with pin portions 13 .and 14 adapted to work through apertures formed in the tubular member and extend into sockets 15 formed in the detach- 6 '14 into the sockets as shown in Figure 1 by .7
The dogs are provided with apertures in which the ends of cables 20 and 21 are se- 7 cured, said'cables passing downwardly over the pulleys 22 mounted in the base member 1 and are then connected as shown at 23 to a cable 24 adapted to extend into the pilots or instructors cock-pit and be so disposed so that it can be readily grasped by the instructor to enable him to pull upon the same, which moves the dogs outwardly and at the same time draws the sleeve 7 downwardly so 'as to detach the upper stick or handle por-8 tion whereby the control of the pupil is disconnected in order to allow the instructor or pilot to control the aeroplane.
In the operation of thejoy stickas herein shown when substituted for the joy stick used .by a pupil learning to fly on the ordinary commercial instructors plane, the sections of the stick are inthe position as shown in Figure 1 and the cable is in position in the instructors cock-pit to be grasped at any time; The pupil can then operate the joy stick to control the aeroplane and i n case the pupil becomes frightened and loses control of the machine, the instructor onlyhas to pull thecable 21am by so doing, the dogs are first drawn outwardly out of the sockets in the lower end of the section 16 which normally has its lower end resting on the nut 6 and as the cable is pulled further, the sleeve 7 is drawn downwardly so that the upper section 16 of the joy stick becomes detached as shown in Figure 3.
In order to hold and guide the sleeve 7 in its upward and downward movement, I provide a reduced section of the member 3 of the stick with a guide key '25 which works in a groove formed in the sleeve as shown in the sectional View in Figure 4.
From the foregoing description it will be seen that I have provided a sectional joy stick which can be substituted for the joy stick now used in commercial planes, the sections of which are detachably connected together so that the instructor can at will detach the portion which is in the hands of the pupil in order to free the control of the aeroplane from the pupil in case he becomes frightened or loses control of the plane, whereby -.the instructor can regain control of the machine and operate the same.
While I have shown certain details of construction, I do not wish to limit myself to these detailsas my invention consists broadly in providing a'joy stick for a dual control machine formed of two sections, the upper or handle section of which can be detached from the lower section at the will of the in- :structor at :any time.
What I-claim is:
1. A joy stick for aeroplanes formed of two sections, one section having a slidably 'mounted sleeve to receive the upper section, dogs carried by the sleeve engaging the upper section and cables connected to said dogs for initially movingsaid dogs out of engagement with the upper section and finallyremoving said sleeve from over the upper section.
2. A joy stick for dual control aeroplanes comprising a detachably mounted base section, a sleeve slidably mounted on the upper end of said section, an upper section mounted within said sleeve provided with sockets, spring actuated pivoted dogs provided with pins adapted to engage the sockets of the upper section, cables carried by said dogs,'pul leys carried by the lower section over which said cables pass, said cables being adapted to operate said dogs to'initially remove the pins from the sockets andto slide the sleeve from over the upper section to detachably connect said section from the lower section.
3. A joy stick for dual control aeroplanes comprising a lower section having a sleeve slidably and non-rotatably mounted on the upper end thereof, an upper section mounted within said sleeve, movable locking memberscarried by said sleeve for engaging socklets in the upper section and single means for first disengaging said locking members and then moving said sleeve downwardly from over the upper section to allow the upper section to be disconnected from the lower section.
4. A joy stick to be used in connection with dual control aeroplanes formed of two sections detachably connected together, one of said sections having a slidably mounted member adapted to embrace the upper section, movable members for locking said sections together and means connected to said locking members for initially operating said locking members and finally moving said slidable member out of engagement with said upper section.
5. A joy stick for aeroplanes formed of two sections, one section having a slidably mounted sleeve to receive the upper section, locking members carried by the sleeve engaging the upper section and means for operating said locking members for initially moving said locking members out of engagement with the upper section and finally removing said sleeve from over the upper section.
In testimony whereof I hereunto afliX 'my signature.
