AIR BRAKE FOR AEROPLANES Filsd March 23, 1957 INVENT OR.
M14) MEl/MEFT BY Patented Dec. 7, 1937 UNITED STATES PATENT OFFICE 1 Claim.
This invention relates to devices for decreasing speed of aeroplanes whereby a landing may be safely effected, and other like purposes attained.
An object of the invention is to provide an 6 effective braking device by which an operator can rapidly reduce the speed of a plane while in the air.
Another object is in the provision of a braking attachment that can be applied to planes when originally built, or installed on existing structures.
A further purpose is to provide a device for the purpose, light in weight, of adequate strength and easily operated from the cockpit.
These valuable objects are attained by the novel construction of parts hereinafter described and shown in the annexed drawing, forming a material part of this disclosure, and in which:-
Figure 1 is a side elevational view of a conventional aeroplane having an embodiment of the invention attached.
Figure 2 is an enlarged fragmentary top plan view of the same, parts being broken away to disclose the construction.
26 Figure 3 is a further enlarged sectional view taken on line 3-3 of Fig. 2.
Figure 4 is a partial plan view of the same shown to a further enlargement.
Figure 5 is a partial transverse sectional view taken on line 5-5 of Fig. 4.
Figure 6 is a transverse sectional view taken on line 6-6 of Fig. 3.
Referring in more detail to the drawing, the numeral l0 designates in general a common type of aeroplane having a propeller H, rudders l2 and cockpit I3.
Mounted to extend above the body or fuselage I0 is a frame supporting a hood l5 of consider- 40 able area having two pairs of spaced downreaching brackets l6 and I1, respectively front and rear, at its forward portion, equidistant from the center.
Journalled in the lower ends of the front 45 brackets I6 is a shaft I8 carrying sheaves I9, similar sheaves being mounted on studs 2| set in the brackets l1, and trained over these sheaves are chains 22.
Another chain 23 is trained over a sheave 24, 50 in the cockpit, and a sheave 25 midway of the shaft I8, a handle 26 being provided to actuate the sheave 24.
Fixed on one of the links of the chains 22 is a lug 21 set in the front end of a bar 28 slidable 55 centrally through a clip 29, its rear end being pivotally attached to the front edge of a fiat plate or leaf 30.
Another bar 32 is firmly secured in the clip 29, and is actuated by a slotted link 33, pivoted in a bracket 34 attached to the under side of the hood I5 and operated by connecting rods 35 fixed at their lower ends to the bar 28, their upper converging ends engaging another of the slots in the link 33.
The rear end of the bar 32 is pivotally coupled to a plate wing 36.
A third bar 33, fixed in the link 29, is similarly pivotally connected to a third plate wing 39.
All of the plate wings, 30, 36 and 39 are provided at their opposite edges, at their rear extremities with fixed studs 40, 4| and 42, respectively, engaged in track ways formed in fan shaped structures, below and at the rear of the hood l5.
The straight, central trackways 43 guide the studs 40 of the central wing, while the upper, angularly divergent trackways 44 guide the studs 4| of the upper wing, and, correspondingly, the lowermost divergent trackways guide the studs 42 of the lowermost wing.
At the outer ends of the trackways 44 and 45 are connecting, arcuate guideways, respectively 46 and 41, leading to return guides 48 and 49, of lesser obliquity, which intersect the trackways 44 and 45.
Gates or switches 5|] and 5| at the ends of the trackways 44 and 45, are spring pressed into normal closed position, preventing the studs from returning over the outgoing path, as indicated by the arrows in Figure 3, while similar gates 52 and 53 guide the studs as the plate wings are moved outwardly into position to exert force against the air when the plane is advancing. I
From the foregoing it will be seen that a simple but effective braking device for aeroplanes has been disclosed in the best known form.
Having thus described the invention, what is claimed as new and sought to secure by Letters Patent, is:-
An aeroplane brake comprising upper, lower and intermediate plates having studs at their rear end edges, guide ways for said studs, said guide ways being disposed at divergent angles whereby said plates are caused to impinge against the air when extended, other guide ways for the return of said studs, gates controlling the path of said studs, and means accessible to an operator to advance or retract said plates.
