FLYING-MACHINE.

Specification of Letters Patent.

Patented Aug. 27, 1912.

To all whom it 'may concern.'

Be it known that I, DAVID SEGAL, a citizen of the United States7 residing at Washington, District of Columbia, haveinvented certain new and useful Improvements in Flying-Machines, of which the following is a specification.

This invention. relates to flying machines4 It is now stated that. the salient feature of my invention is to provide means for correcting the tendency of the machine to tilt to an excess degree and for restoring the equilibrium of the .machine When the latter is in flight Without the provision of mechanism for the collective and simultaneous control of the balancing planes, rudders or other movable parts of the machine which must only' be disturbed with the utmost. care, and to provide such means that can he applied to any Well known machine without necessitating elaborate changes in the construction thereof; further the provision of such means which will include a suspended weight beneath the gliding surface of the machine on a rigid sliding support which can be extended perpendicularly beneath the gliding; surface to effect relative radj'estimer-,nts of the latter and. the vWeight whereby it can be extended to any desired position according to the pitch of the chine. from its correct gliding position.

Another object of the. invention is to provide such stability mechanism which, when adjusted to .an inoperative' position. will be Wholly out oi" contacting rrexiinit-y with the surface ot' the ground the. land.- or launching of the flying machine.

-n the drawings, forming a portion of this speciiication and in, which like numerals of reference indicate similar parts in the several viewsiwligure l is a transverse section through a biplane showing my invention applied thereto, parts being shown in full linee and the Weight in its maximum uppermost position. Fig. is a front view fit' the saine. Fig. 23 is a longitudinal. sci.:- tion through the driving shaft showing the Jompanionclutch elements thereon. is a section on l--l of liigg. l. E a section on line .5mof lf'i l.. a diagrammatic vien' of l e ily' me .eine illustreting 'weight in maximum lowermost pnsition. illustreti in dotted vlines the tilted position of the machine and :the initial position of the Weight.- Fig. Tis :a perspective view of the Weight control.

It is now stated that my stabilizer is de` signed for use upon any well known form of liying machine of the heavier or lighterthan-air type and only with a viewI of clearly illustrating the invention has the same been embodied with the biplane structure l herein shown. This structure .is shown to include the upper and lower planes or gliding surfaces 2 and 3 which are connected by the usual stanchions or uprights 4, the motor base or platform 5, the motor and Lhe propeller or driving shaft 7 and its propeller 8. i

The stabilizer comprises a rigid support or bar 9 which extends perpendicular to the plane of the gliding surfaces of the machine and is mounted to slide in fixed guides l() on the iframe of, the machine in line with the renter of gravity. This support has ixedly connected thereto at its lewe-r end a 'weight l1, which is preferably spherical so as to offer little resistance to the travel of the machine, the said Weight being loca-ted beneath the lower plane or gliding surface 3 and it is adjustable with relation thereto in a manner hereinafter described. The Weight support 9 is provided with a longitu dinal series of transversely arranged teeth l2 which adapted. V:for intermeshing en gagement with the driven gear Wheel I3 on the countershatt lil.

The counter ft mounted in suitable hea brach!" which from the base i) and lixeeliy .mounted on said shaft are the driven pulleys i6 and il. the former be" ingv cennec the belt i8 to the pulley-like idle clutch element 19 on the driving shaft '7. The pulley 1'7 is connected by the belt 20 with the pulley-like idle clutch elemenfl on the driving sha-ft. The belt 2O has parallel leads, and the connection of the. belt with the pulley 2l permits the countershaft ist to rotate in an opposite mov-em nt le that i "martedi thereto through The elements l@ end '121 cal gre surfcces similar surfaces 23 aflaiited te en ion oii movement element Slet has secured thereto a key 25 which. extends into the longitudinal keyway 2G in the driving shaft whereby movementv will be constantly transmitted to the element. The element 24 has an annular groove 27 therein to receive the collar 28 on the. shift lever 29. The extensile springs 30 which are interposed between the elements 24, 'i9 and 21 serve to hold the element 24 in neutral position. It is now clear that means are employed for effecting the instantaneous rotation of the countershaft in either direction so that the bar 9 can be made to climb or fall as the occasion may demand.

The shift. lever supports a fixed pin having oppositely extending portions 31 and 32, the portion 3l being extended through the elongated slot 33 in the link 34 and the portion 32 being extended through a similar but oppositely extending slot 35 in the link 36. A rock erin 37 is mounted 1n a suitable` bracket 38 upon the frame of the tlyino machine, and as shown, the lower end o? said arm carries a pin to which the lowe and rear endfof the link 34 is pivoted. The upper end of said rock arm has pivoted thereto, at 40, the upper vend of the link 36. he links 34 and 3G, and the actuating` member Lil and control lever 42 formthe means for shifting the clutch element 24 to operative and inoperative positions.

Y The actuating member 4l has fixed thereto the spaced pins 43 and 44 between which the support 9 is adapted to slide. Near the lower end the support carries an operating member or cani 45 which. is adapted to ride against the pin 43 on the maximum uppermost travel of the support and thereby move the actuating member 4l to impart rocking movement to the shift link 29, resulting in the neutral shift of the keyed clutch ele-- ment 24. The support also has xed thereto near its upper end a similar cam 46 which may engage the pin 44 to also cause the neutral shift. to be imparted to the element.

ln order that the support 9 can he locked against sliding movement `.vhen the element 24 is in a neutral position, I provide a brake shoe 47 which is secured to a stem 48. This stern is slidahle in guide brackets 49 on the traine of the dying machine, and as shown,

the stem has secured thereto a shoulder 50 against which one end of a helicalk extensile spring 5i bears, the opposite end of the spring being engaged against one of tire guide brackets 49, whereby the shoe 47 i'iornially held in an applied position. The ioe ai iai y of U--configuration in cross sectVv i? as shown in Fig. 4 of the drawings, so aste provide guide tianges to embrace the sides of 'the support 9.

The i'rictional engagement of the. surface 53 of the brake shoe. against ther-:apport 9 is Suiiicientto hold the support against sliding mount-ed on the pin 39 of the rock arm 37,`

whereby on movement of the rock arm in one direction the brake shoe will be usted to a released position.

The motor C and the elements operated therethrough which include the countershaft 14 form means whereby the support 9 can be readily adjusted to an. operative or an inoperative position. In order that the support 9 can he operated on failure of the motor 6 to work, I provide the countershaft i4 with a sprocket gear wheel 55 which is connected by the drive chain 5G to a similar sprocket. gear Wheel 57 on the Shaft 58. The shaft 58 is supported in any suitable well known manner in the frame of the lying machine and at one end it is provided with a bevel-pinion 50 which meshes with a similar bevel-pinion G0 on the crank shaft (il. This crank shaft carries a suitable hand wheel 62 which is preferably located adjacent to the controlling lever 42 and the latter and the former are also disposed in controlling proximately to the aviators7 seat.

The slots 33 and 35 are disposed in intersecting planes and on reference to Fig. 1 of the drawings it is seen that the pin 3l on the shift lever 29 engages against the walls of these slots at the inner ends thereof. Nov: it is stated that when moving the control lever 42 in the direction of the arrow a the actuating rod 4i will be controlled so as to cause the pin 3l to bear against the inner end ot' the slot 35 suiciently to impart rocking movement to the rock arm 37. This causes the draftI rod 54 to impart the necessary movements to the brake shoe 47 to cause. the release of the latter from the support 9. Simultaneously with this action the link 29 will be shifted to causo the clutch element 24 to engage with the clutch element 2l, the latter becoming a ixed partoi the driving shaft i' so that power will be transmitted to lthe oountershaft i4 to cause the controlled descent of theA weight At the. maximum lowering oftl the support 2 the cam 4G will be brought to bear against the pin 44 effecting a shift of the actuating rod 41 and also causing movement to be imparted to the shift link 29 'to restore the driving clutch element' to its neutral position.l -Reverse movement oiz the support 9 will tiring the cam 45 into engagement with the'pin 43 with the resultant neutral shift of the driving clutch element.

t is now thought that the essential features of the invention are sutiieiently described te enable one in the art to clearly Vunderstand the invention together with the subsequent brief description of the opera-- tion of the invention.

The apparatus is adjusted previous to element'lQ4 to respond to the action of the obviously appears that, at the discretion of 110 are so associated to receive-the support 9 that the greatest possible leverage upon the 4machine is obtained, the lower machinefmeans forv controlling movements comprising a movable member disposed per- 'the launchingof the flying-machine so as to.
