Thisinvention relates to a rudder bar ad- Having thus described the invention, its

7 ,8 justable foot rest for aircraft, and has for operation is as follows:

its object to provide a device of this class which may be quickly adjustable to meet varying ranges for different pilots, and which will permit under alladjustments the pilots heel to rest on the floorwhen desired.

. With this object in view the invention consists of the novel construction of the device and in certain combinations of parts, all of wards specifically pointed out in the append ed claims.- I 7 Referring to the accompanying drawing- Figure 1 is a plan view of the device; Figure 2 is an elevation thereof; and, Figure 3 is an end elevation of the same. Like numerals of reference indicate the same parts throughout the several figures, in

which I 1' indicates the rudderbar which is preferably tubular in form, pivoted at 2 to the mounting bracket 3-. 4: indicates the ruddercable-attaching clips and 5 indicates the adjustable foot rests. I

' Suitably secured to the rudder bar 1 at each end thereof,'is a pair of flanges 6, each of which is perforated to receive the bolts 7. 8 indicates the substantially U-shaped foot rest frames which include a vertical body portion 9 and a flanged top portion 10, the said frames 8 being L-shaped in cross-section.

In each of the parallel arms 11 of these frames, I provide an elongated longitudinal slot 12, and in the lower edge of said arms I provide a series of. notches 13, and a series of "substantially longitudinally extending tongues 14 lying directly under the effective portions of the said notches.

15 indicates the foot-rest, which as shown in the drawing, comprises the transverse body portion 16 and two triangularly shaped ends 17 disposed at right angles to the said body portion. Each end portion of the foot-rests .is provided with a'perforation to receive a bolt 18 and is alsoprovided with an arcuate slot 19 to receive a similar'bolt 20, both of which bolts are passed through the frame 8 adjacent the end of the elongated'slot 12.

rudder bar to the range of the pilot, the'U- shaped frames 8 are moved rearwardly to disengage the. notches 3 from the lowermost bolt 7, and the said frames are then moved upwardly pivoting on the uppermost bolts 7. The frames are then moved forwardly or rearwardly as desired and are then moved downwardly so tha'tone of the notches 13 drops over the lowermost bolt 7 A slight movement of the frame in a forward direction carries the adjacent tongue 14 under the lowermost bolt 7 in the manner as shown in Figure 3. The desired longitudinal position of the frames 8 are thus obtained. In order to adjust the foot rests 15 conveniently to the feet of the pilot, the rests 15 are swung on their pivotal bolts 18 and when the desired angularity of the rests are thus obtained, said bolt 18 and the bolt 20 are tightened to securely hold the rests 15 in proper adjusted position.

Having thus fully described the invention, I do not wish to be understood as limiting myself to the exact construction herein set forth, but I consider myself clearly entitled to all such changes and modifications as fall within the limit and scope of the appended claims.

What I claim as new and desire to secure by Letters Patent of the United States, is:

1. A device of the character described, including a rudder-bar,a substantially U-shaped frame at each end of the rudder-bar, the arms of each of said frames being provided with an elongated longitudinal slot, and a series of notches formed in the lower edge of each of said arms, means stationary with respect to said rudder-bar, to be received by said slot and notches to provide adjustment of said frames, and a foot-rest pivotally mounted in each of said frames.

2. A device of the character described including a rudder-bar,a substantially U-shaped frame at each end of the rudder bar, means for adjusting said frame transversely with each of said frames, and means for adjusting the foot rests with respect to said frames.

3. A- device of the character described in-e eluding a foot operated member, a foot rest, a substantially U-sha'ped frame adjustably mounted on said member and supporting said foot rest, and'means for holding said frame 7 in adjusted position therewith.

4. A device of the character described in cluding a foot operated member, a substantially U-shaped frame adjustably mounted on said member, means for holding said frame in adjusted position, and further means providing a foot'rest on said frame, said foot rest being pivotally mounted on said frame.

5. In a control device for aircraft, a foot operated member, means on said member 10r0- viding'an adjustable foot rest, having fore and aft adjustment-in relation to said member, said foot rest having further means to permit a tilting of said foot rest'about an axis in transverse relation to said member. y

In testimony whereof I aflix my signature.
