James manners, or smmoaa, mum.

To all {whom it my concern:

Be it known that I, James RICHARDS, a

citizen of the. United States, residing at Baltimore, State of Maryland, have invented a new and usefulAeroplane', of which the following is a specification.

This invention relates to aero lanes and more especially to means where y a quick.

the aviator whereby the twosections can be shifted relative to each other about a transverse axis, thereby to allow the nose portion of the machine to be pointed upwardly while the remainder of the machine is supported by the running gear on the ground, and facilitating the abrupt ascent of the machine from a limited area.

With the foregoing and other objects in view which will appear as the; description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit or sacrificing any of the advantages of the invention as set forth in the appended claims.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings- Figure 1 is a view partly in side elevation and partly in section of the areoplane, one of the positions of the nose portion being shown by dotted lines.

Fig. 2 is an enlarged vertical transverse section on line 22, Ifig. 1.

Fig. 3 isa view in diagram showing how the cam operates to shift the nose.

Referring to the. figures by characters of reference, 1 desi ates the rear or tall portion of the body of the aeroplane, the same being provided with running gear 2 and carrying a rudder 3 which can be operated in suitable manner, as bv means of foot pedals 4 operating an endless belt 5 engage Specification of Letters ma; P t t d Dee. 16,191. 9.

a ear 10 secured to a post 11 having a hand w eel 12. Secured to the shaft 8 so as to rotate therewith are cam arms 13 haying rfctk tgaeth 14 and formed in each arm is a. s c 1 The front section 16 of the aeroplane I body carries the sustaining plane. :17, the

ropeller 18 and the engine, not shown. his section is hingedly connected at thetop of the rear end thereof to the section 1, as shown at 19. Extending rearwardly from each side of the section 16 is a pairof arms 20, the arms of each pair being connected by a pin 21. The arms 20' are located at each side of the respective cam arms 13 and the ins 21 are slidably mounted in the slots 15. ournaled between the arms 20 of each pair is a gear 22 constantly in mesh with t e teeth on the adjacent arm 13.

From the foregoing it will be apparent that when the arms 13 are swung downwardly-they will rotate the gears 22 andthrust therethrough against the section 16, causing it to swing upwardly, as indicated by dotted lines, in Fig. 1, so that the rotating propeller will exert an upward pull upon the aeroplane and cause the machine to move upwardly at an abrupt angle. By reversing the movement of the arms 13 the front section 16 will be moved downwardly. (The action of the arms on the nose of front section 16 of the machine has been indicated i in diagram in Fi What is claim is I 1. The combination with an aeroplane body including a rear section, and. a front section hingedly connected to and adapted to swing upwardly and downwardly relative to the rear section, of a cam arm mounted for oscillation within the rear sec tion, means on the front section for slidably engaging the cam arm, revoluble means on the front section for receiving the thrust from the cam arm, and means for actuating the cam arm.

2. The combination connected front and rear sections of an aeroplane body, of longitudinally slotted cam arms mounted on the rear sect1on,means for with the hingedly,

the front-section for sliding en'gagement ing a wheel 6 on the shaft 7 of the rudder; with the arms, n rwi s Ma aw and revohible means on the front seeti'on'for receiving the thrust from the arms.

3. The combination with hingedly connected frontv and rear sections of an aeroplane body, of a shaft journaled in the rear section, longitudinally slotted arms conneeted to'the shaft and constituting cams, each arm having a longitudinal slot, rack teeth upon each arm, gears freely revoluble on the front section and engaged by and adapted to receive thrust from the toothed arms; and means uiaon the front section and projectin into the slots in the arms for holding t e arms and gears in mesh. I

In testimony that I claim the fiorgoing as 15 my own, I have hereto aflixed my signature in the presence of two Witnesses.

JAMES RICHARDS.
