CORPORATION OF AIRCRAFT, IN GLUDING PEDALS FOR SAME Original application filed January 19, 1929, Serial No. 333,603. Divided and this application filed May 7,
1929. Serial No. 361,178.
The present invention relates to foot control systems of aircraft of all kinds. It hasparticular reference to the form and mounting of the pedals themselves and likewise to a dual control system according to which the pilots sit side by side. In this latter connection, the invention relates to means whereby either of two sets of pedals may be operatively connected with transmission members to which are secured cables or the like leading to the rudder.
This application is a division of my copending application Serial No. 333,603 filed January 19, 1929.
In the accompanying drawings, the invention has been shown as'appli ed to an amphibion as shown in the above mentioned application. As stated above, however,the invention may be applied equally well to other types of aircraft, the present showing as a whole being intended to be merely illustrative of the invention and in no wise restrictive.
In the drawings:
Figure 1 is an elevation of a portion of an amphibion showing particularly the body boa-t thereof, part of the side wall of the latter being broken away.
Figure 2 is a transverse section of the bodyboat at the front of the pilots compartment.

Referring to the drawings, 10 indicates the body-boat of the amphibion in the forward a section on line 77 of Fig- 1 portion of which is arranged a pilots compartment 11 provided with seats 12 and 13.
placed side by side- The reference numeral 14 indicates the upper main plane and 15 designates the-lower plane. The empennage shown in Figure 1 at 16. Retractible landin wheels 17 are provided, these being controlled by mechanism fully described in my copending applications Serial No. 314,585 filed October 24, 1928 and Serial No. 333,603, filed January 19, 1929.
Other features with which the present invention is not particularly concerned are the centrally disposed engine controls 18, stabilizer controls 19 and aileron and elevator control stick 20. As described in the parent ap plication, the control stick 20 has pivoted to the upper end thereof an arm 21 which supports a wheel 22, the arm being swingable in front of either seat 12 or 13 as circumstances may require. 7
The two sets of pedals are identical and consequently only one need be particularly described. Reference will accordingly be had to the set in front of the left hand seat 13, the two pedals being designated as 23 and 24. Each pedal is in the form of what may be termed a runner and has a rear horizontally extending portion and a forwardupwardly inclined portion provided with a heel cleat as at 25. Each runner comprises a pair of longitudinally extending U-section spar members 26 and 27, these being reinforced at theangle by members 28 riveted in the channels.
. A metal plate 29 is supported on members 26 and 27 and extends throughout the length of the runner and a layer of some suitable nonslippery material 30 is superposed on plate 29.
31 are guided in U-section tracks-L33.
In order to prevent vertical displacement of the rear or horizontal portion of the pedal, a longitudinally extending I-beam 34 is secured to the under surface of plate 29, the lower flange being ust clear of the floor and taking under overhanging flanges of parallel Z- bars 35 and 36. I
The forward end of each pedal is supported on a normally vertically extending stirruplike lever comprising side members 37 and 38 and a cross bar 39. Each lever is mounted on an axle 40 extending transversely of the machine and mountedin pedestals 41 and 42, all of the axles lying in the same line. The forward extremities of members 26 and 27 are provided on their lower sides with recesses adapted to receive a bar 39, accidental displacement of members 26 and 27 relative to the bar being prevented by plates 43 and 44.
It will be seen that the runners thus mounted may be reciprocated in substantially horizontal planes and are supported for such movement on the forward levers and the rearward rollers. Ordinarily, the pilot will rest his feet on the inclined portion of the pedal, although if a change of position is desired they may rest on the horizontal portion. If a pilot wishes to remove his feet from the pedals entirely, when the machine is under the control of the other pilot, a cover member 45 is provided which is slidable in guides 46 and 47 and may be drawn out so as to substantially cover the horizontal portions of the runners. At its forward end, the cover plate is provided with a hand slot 45.
Stirrup- like members 37 and 38 which support runner 23 are provided with forwardly extending lugs as at 46 (Figure 4), these lugs supporting a pin 47-parallel to pin 40. Pin 46 projects beyond member 38 into a recess formed in an arm 48, which likewise extends parallel to the pivoting axis of all the levers and has a rearwardly extending lug 48 in an aperture of which is engaged the projecting end of pin 40 upon which the supporting lever for runner 24 is mounted. Members 37 and 38' of this lever have rearwardly extending lugs 46' at their lower portions which support a pin 47. Pins 47 and 47' are equally spaced from the pivotal axis of the levers and upon rocking movement of the latter travel in arcs of the same circle.
Arm 48 supports at its end a coaxial pin 49, this pin terminating in the same longitudinal plane of the body-boat as pin 47.
Disposed centrally of the pilots compartment opposite pins 47 and 49, is a substantially square frame comprising four marginal strips which support at their points of junction, that is, at the corners of the square, pedestals 50, 51, 52 and 53. The frame is guided for shifting movements transversely of the compartment by Z- bars 54 and 55. Pedestals 50 and 51 are provided with vertical grooves in which is movable a-slide 56 which is provided with a horizontal slot 56. Headed ferrules 57 and 58 are slidable on the ends of ins 49 and 47 respectively, the flanges of these ferrules overlying the margins of slot 56' as is indicated in Figure 9 in particular.
It will be obvious from the above description that upon moving runner 23 forwardly and runner 24 rearwardly equal distances, pins 49 and 47 will move downwardly through equal arcs and that ferrules 57 and 58 which slide in slot 56 will inforce a downward movement of slide 56. Since the movement of pins 49 and 47 is balanced, slide 56 will move in strictly horizontal planes and there will be no tendency to jam it in its guides.
Disposed centrally of the slide frame are a pair of standards 59 and 60 which through the intermediary of pin 61, in line with the pivoting axis of the pedal supporting levers, supports a pair of segments 62 and 63. Segment 62 has a transversely extending portion 62 which at its ends supports pins 64 and 65 at an equal distance from the pivotal axis of the stirrup levers to that of pin 49. Segment 63 likewise has a transverse portion supporting pins 66 and 67 adapted to oscillate in the same are as pin 47'. Springs 68 and 69 normally pull the segments forwardly and to the latter are attached the rudder control cables 70 and 71.
As has been mentioned above, the pedal arrangement at the right hand side is identical with that at the left, this assembly presenting pins 7 and 73 rockable in arcs of the same circle as pins 49 and 47. These pins have slidable thereon coupling ferrules 74 and 75 guided in a slot of a slide 76 which in turn is guided in grooves in pedestals 52 and 53. 1
It has been stated that this supporting frame for slides 56 and 76 is displaceable transversely of the machine. At its left hand limit of movement, as illustrated in Figure 3, ferrules 74 and 75 which ride on pins 72 and 73 are brought over the ends of pins 65 and 67, While ferrules 57 and 58 will be free of pins 64 and 66. Under these circumstances, pins 65 and 67 are forced to follow the movements of slide 76. Inasmuch as these pins are on different sides of supporting pin 60, a downward movement, for example, will impart forward movement to segment 62 and an equal rearward movement to segment 63. Thus to sum up the sequence of operations, sliding movements of the pedals cause oscillations of pins 72 and 73 which in turn cause vertical reciprocatory movements of slide 76 thus oscillating pins 65 and 67 and imp arting opposite oscillatory movements to transmission members 62 and 63. Equal movement of the segments will be inforced due to the fact that cables 70 and 71 are connected in the usual manner to the cross bar of the vertical rudder. Since this manner of connection is Well understood, it has not been thought necessary to illustrate it in the drawings.
Under the circumstances above described the machine has been assumed to be under the control of the pilot sitting at the right. If the control is to be changed, it is only necessary pins 64 and 66 while ferrules 74 and 75 will be moved out of engagement with pins and 67. This movement is under the control of either of the-"pilots.
Mounted on the compartment floor immediately to the rear of the coupling frame are a pair of transversely spaced segments 77 and 78 to which are pivoted levers 79 and 80. Each of these levers has at its lower extremity a pin shown at 81 (Figures 4, 8 and 9), this pin engaging in. a vertical slot of a pedestal 51 or 52. Each lever has a spring pressed plunger as at 7 9 and 7 8', these being adapted to cooperate with a pair ofspaced serrations on the respective segments. The plungers do not positively lock the levers against movement, but at the same time are adequate to hold the coupling frame in either of its coupling positions. Movement of lever 79 by the pilot at the left, however, will inforce movement of lever 80, without manipulation of the latter by the pilot at the right. It willbe understood that with the levers in the position shown in Figure 9, the pilot at the right will be-in control of the vertical rudder, while movement of the levers to the left to their other limit position will place the rudder under the control of the pilot at the left, freeing it entirely from the control of the other pllot.
