shaft'2Q ,and operates in the opening 15.
The disks 31 and 32 are connected by bars
33 and 34 whereby the rotation of one of
said disks will produce a corresponding ro-
5 tation of the other.
The shaft 20 and rod 29 are disposed in
longitudinal alinement, one end of the shaft
20 being rotatably mounted in the adjacent
end of the rod 29. The rod 30 is also dis-
10 posed in longitudinal alinement with the
shaft 20 which latter has one end rotatably
mounted in the adjacent end of the rod 30.
Fixed on the end of the rod 30 adjacent the
frame A is a disk 39, while another disk 40
15 is loosely mounted on the shaft 20 and op-
erates in the opening 17. The disks 39 and
40 are connected together by bars 41 and 42
whereby said disks may be rotated in uni-
son. Formed on the disk. 32 is a lever ex-
20 tension,43 which carries a spring pawl 44
cooperating with a . toothed segment 45
mounted on the platform 14. From this
construction it will be apparent that by. op-
* erating the lever extension 43 the disks 31
25 and 32 will be rotated and such rotation of
said disks will in turn rotate the rod 29 and
the plane 27 to dispose the latter at different
angles of incidence to the atmosphere.
Through the medium of the pawl 44 it will
30 be obvious that the parts just referred to
can be locked so as to maintain the plane 27
adjusted at a given angle of incidence to the
atmosphere. Formed on the disk 40 is a
lever extension 46 which carries 'a spring
35 pawl 47, the latter coperating with a
toothed -segment 48 mounted on the plat-
form 14. By this construction it will be ap-
parent that upon the rotation of the disk 40
through the. medium of the lever extension
40 46 the rod 30 will be rotated to dispose the
plane 28 at different angles of incidence to
the atmosphere and that said plane can be
locked in a desired adjustment through the
medium of the pawl 47 and toothed seg-
45 ment 48.
Fixed . upon the shaft 20 and disposed
substantially. in embracing relation to the
platform 14 are the arms49 and 50 of a V-
shaped frame B the apex of which is di-
50 rected forwardly of. the aeroplane. The
free ends of the arms 49 and 50 extend rear-
wardly of the shaft 20 and are.provided re-
spectively with laterally directed fingers 51
and 52 for j purpose that will presently ap-
55 pear. Rotatably mounted on the forward
end of the frame B is a propeller 53 having
a rearwardly directed axial extension 54
upon which is fixed a beveled gear 55. Ro-
tatably mounted in bearings 56 carried by
60 the arm 50 is a shaft 57 which has fixed
thereon a beveled gear 58 meshing with the
gear 55. Also journaled in bearings 59 car-
ried by the arm 50 is a shaft 60 the forward
end of which is connected to the rear end ofthe shaft 57 by a universal joint 61, while 65
the rear end of said shaft 60 has fixed there-
on a beveled gear 62 which meshes with the
beveled gear 26 fixed on the sleeve 21.
Fixed on the shaft 20 is a lever 63 which
carries a spring pawl 64 coperating with a 70
toothed segment 65 mounted on the plat-
form 14. By this construction it will be
apparent that by operating the lever 63 the
forward end of the frame B may be raised
and lowered to dispose the propeller 53 at 75
different angles of incidence to the atmos-
phere. Loosely mounted on the shaft 20 ad-
jacent the outer side of the arm 49 is a bar
66 provided with an opening 67 adapted to
detachably receive the finger 51. The rear 80
end of the bar.66 is provided with a trans-
verse dove tail groove 68 for a purpose that-
will presently appear. Loosely mounted on
the shaft 20 adjacent the outer side of the
arm 50 is a bar 69 which is provided with 85
an opening 70 for detachably receiving the
finger 52. The rear end of this bar 69 is
also .provided with a transverse dove tail
groove 71 for a purpose that will presently
appear. Slidably engaged, in the grooves 68 90
and - 71. are ribs 72 and 73 respectively
formed on the inner ends of respective arms
74 and 75 of a V-shaped frame C. Rota-
tably mounted on the frame C is a propeller
76 provided with an axial extension 77 upon 95
which is fixed a beveled gear 78. Journaled
in brackets 79 carried by the arms 75 is a
shaft 80 which has fixed on one end thereof
a beveled gear 81 which meshes with the
beveled gear 78. Also journaled in brackets 100
82 carried by the arms 75 is. a shaft 83 one.
end of which has fixed thereon a beveled
gear 84 meshing with the beveled gear 26
while the other end thereof is connected to
the adjacent end of the shaft 80 by a uni- 105
versal joint 85.
Loosely mounted on the shaft 20 and op-
erating in the opening 16 is a lever 86 the
lower end or which is provided with a rear-
ward extension 87 having an enlarged por- 110
tion 88 formed with a slot 89. This lever
86 carries a spring. pawl 90 which cop-
erates with a toothed segment 91 mounted
on the platform 14 for the purpose of lock-
ing said lever 86 against pivotal movement. 115
Disposed beneath the platform 14 at the
rear of the shaft 20 are spreader arms 92
and 93. The rear ends of the arms 92 and
93 are connected together as at 94, while the
forward ends of said arms are secured re- 120
spectively to the rear ends of the bars 67
and 69. Slidably engaged. through open-
ings in respective arms 92 and 93 is a rod
95 for a purpose that will presently appear.
Formed integral with the lever 86 above the 125
shaft 20 is a rearwardly extending toothed
segment 96 and pivoted upon'said lever 86
is another lever 97 which carries a spring
