UNITEDJSTATES JOHN BUCKLEY,:0FMATTA1?A1I, AS AC USETTS.
CONTROL MEoHANISm.
To allwhomitmay'conce'm: p Be it known'that I JOHN BUOKLEY, a citi zen of the United States, residing at Mattapim, in the county of Suffolk and Stateof assa'chusetts, have invented certain new and useful Improvements in Control Mechanism; and I do hereby declare the following to be a full, clear, and exact description of the same reference being had to the accompanying drawings, forming'part of this specification.
This invention relates to a control mechanism, which while particularly intended for the stabilizing of aeroplanes by warping of the wings and by control of the aerial'rud ders is also intended for general control operation, as for example the governing of a steam valve or a damper for any purpose whatsover. .l
The object of the present invention is to provide a mechanism of this type which while relatively simple in construction will act positively and with s'utlicient power for the purpose required upon Slight or delicate movement of the governingmechanism.
In the drawings,' v
Figure l'is a side view of my device partly in section. v
IFig. 2 is a central vertical section.
The standard 10 rises from the base 11 and rotatably supports the shafts. 12 and 14.
On one side of the Standard 10, the shaft 12 carries'a crank or eccentric 15 which operates to raise or lower the slotted retainer 16 which slidably receives the lower T-shaped end 17 of a toothed yoke 19 integral with or rigidly secured to the rod 20. At its other end the shaft 12 carries a pinion 22 driven by a rack 23 cut in the upper face of an armature 24 sliding within the solenoids 26 and 27.
The arms 17 and 28 of the yoke 19 are 7 formed with rack teeth 29 spaced apart a sufficient distance to clear the teeth of the pinion 30 which is keyed to the shaft 14. The yoke is pivotally mounted and may be raised or lowered to bring the rack teeth on either 17 or 28 into contact with the constantly rotating pinion 30. As illustrated in Fig. 2, the pinion 30 is conveniently formed in spool shape with a guiding flange 31 at either side to guide the yoke in its pivotal movement and insure the meshing of the pinion and rack. The rod 20 which is integral with the yoke 19 or permanently secured thereto is directly connected to the 'Application filed march 25, 1921; Serial No. 455,425. 1

float, an inclinom'eter, a compass or some such mechanism. The other side of the 'battery 34"is con nected to the spring contacts 42 and 43 one on either side of the double solenoid and nor mally pressingagainst thej conductors '44 and 45.respectivelv, formingthe free end of the coils of 27 and 26. The pins 46 p'ermanently Secured to the-yokef19 areof insulating material'and move in a path so 'as, to
raise the freeends of the springs 42'and4 3 and thereby to break the circuitincluding the solenoid: If desired a single pin may be springs.
rent passing from the battery 34 .to the conused which would then beplaced centrally of the yoke and would; operate either of the The operation of the device is as follows:
'WVhen the governing means moves1a ,suflicient distance to bring thev end of the switch '35 into engagement with oneof the contacts, say 37, the solenoid 26 is energized, the ourtact 37 through the solenoid to conductor 45 and through the Spring 43 and wire 47 back to the battery. The energizing of the solenoid 26 causes the armature 24 to be drawn to the left in Fig. 1 rotating the pinion 22 in a clock-wise direction. By means of the crank or eccentric 15 this motion of the pin-f I ion is translated into a downward movement of the slot-ted member 16 thus drawing the upper arm 28 of the yoke into contact with the pinion 30 which constantly rotates at a slow speed in a clock-wise direction. The
movement of the armature 24 is such that when it is in mid-position the slotted member 16 is in neutral with neither of the racks engaging the pinion 30, but when the armature 24 is at either end of its travel the pinion 30 is in meshwith the rack. A spring 21 or other mechanism is provided to maintain the yoke in neutral position when no current is -fiowi-ng, the strength of this spring being sufficient to return the armature 24 to mid-position when no currentis flowing through the coils.
Movement of the pinion 30 under the circumstances just stated will move the rod by any'reason the switch-85 is not restored to neutral position in time to check the movement of the rod 20 the insulating pin 46 will raise the spring contact 42 from the conductingmember 44; connected to the end of coil 27 at which time the spring will return the yoke to mid-position, thus freeing the rack from the teeth of the pinion 80.
What 1 claim is I l v1.
