3 Claims. (01. 242-437) This invention relates to novel and useful improvements in devices for use in conjunction with controlling the path of flight of a flying model aircraft.
An object of this invention is to support on a common base a pair of reels which are drivingly interconnected with each other, whereby upon rotation of one reel, the other rotates in the opposite direction for paying out or taking in line.
Another object of this invention is to detachably support the reel, whereby a simple maneuver of a spring allows one of the reels to become disengaged with relation to the other, thereby regulating the length of one line with respect to the length of the other may be accomplished.
Another purpose of this invention is to apply a positive locking mechanism on one reel, cooperative with the base supporting both of the reels.
Another purpose of this invention is toprovide an extremely practical device of the character to be described which includes and incorporates various structural features of importance such as the cam type locking mechanism for the reels, the single spring for each reel serving the dual purpose of retaining the reel on the base and also for guiding the line as it is being payed out and in, and others.
Ancillary objects and features of novelty will become apparent to those skilled in the art, in following the description of the preferred form of the invention, illustrated in the accompanying drawings, wherein:
Figurel is a perspective view of the preferred form of the invention;
, Figure 2 is an elevational side view of the device;
Figure 3 is a front View of the device shown in Figure 2;
Figure 4 is a plan View of the device shown in Figure 2;
Figure 5 is a sectional view taken substantially on the line 5-5 of Figure 2 and in the direction of the arrows;
Figure 6 is a sectional view taken substantially on the line 6--6 of Figure 4 and in the direction of the arrows;
Figure 7 is an enlarged fragmentary sectional view of the locking mechanism, and;
Figure 8 is an enlarged perspective view showing a sleeve with a cam at one end thereof, forming a portion of the locking mechanism.
There are several types of control mechanisms known in the art. Illustrative of a device of this nature is the subject matter of Patent No. 2,4065%. This patent features the utility of a double reel type device capable of winding and unwinding one line with respect tothe other, thereby lengthening or shortening the lines. The present device deals with similar subject matter. A base 10 is provided with a hand opening l2 at one end thereof and has suitable handle portion l4 associated therewith. This base has bent portions I6 and [8 respectively provided therein, the slots 20 being supplied thereadjacent. Shafts 22 and 24 respectively extend from the raised portions substantially perpendicular to the plane of the base l0. These, shafts accommodate gears 26 and 28 respectively for rotation.
The gears 26 and 28 are rigidly attached to the hubs of the reels 30 and 32, by any suitable means such asthe locking pin 34. The said gears and their associated reels are simply slid axially on the shafts 24 and 22, the gears projecting slightly through the central slot 30 in order that they are in mesh with each other. 7
It is apparent that upon rotation of one of the reels, the other will be rotated in the opposite direction. In the operation of the device, this situation and condition occurs.
A line 33 is attached to the reel 39 and maybe of any conventional material such as wire, as is now used extensively in the art. A second identical wire or line 39 is attached to the other reel. Both of the lines have safety pin type locking mechanism 40 at their free ends in order to attach to the conventional control cables, connecting with the control surfaces of a model aircraft. The conventional control by control surfaces of the aircraft is well known and need not be discussed herein.
Flanges 44 and 46 respectively extend at substantially right angles to the plane of the base I 0 and have slots 48 and 50 respectively therein. The control lines 38 and 39 extend through the slots 48 and 50 and are guided thereby. The ends of the slots adjacent the center line of the base [0 are tapered slightly, as is seen at 52 in order that the line may be guided smoothly under operative conditions.
Attention is directed now primarily to Figure 7 wherein a plate 5% is shown as being attached by rivets 58 or the like to the reel 32. Disposed in an aperture (unnumbered) in the plate 56 is a sleeve Bil which has a bore 62 and a counter bore 54 therein. A pin 63 isslidable in the bore and through the counter bore. The pin 66 has a button 68 at the end thereof which is rigidly attached to the pin 66 by any suitable means.
A cam follower Hi formed by a pin extends at right angles from the side of the axially slidable pin 66 and is in operative engagement with a cam i2 formed at the end of the sleeve. Noting Figure 8 it will be seen that a recess M is supplied at the apex or highest point of the cam in order to accommodate the pin. When the cam follower is rotated to such a position that it rests in the recess M, the pin 93 will be retained in a locked position.
Constantly biasing the pin and the button 68 toward the base It is a spring 18 or other suitable resilient biasing means. This spring reacts on the sleeve 69 and also on a collar 80 formed on the pin 65.
It is readily appreciated that the pin is slidable through a bore (unnumbered) formed in the reel 32 and in a selected one of the number of apertures or openings, each of which is indicated at 82. The opening being in the base [0, it is now readily apparent that the pin will prevent rotation of the reel 32, when it is in one of the openings 82. The reels being drivingly connected to each other by the gear means described, rotation in both reels will be simultaneously halted upon application of the described locking means. In order to facilitate winding and unwinding a smoothly contoured outer sleeve 86 is rotatably disposed on the exterior surface of the sleeve 6|] and has a matching curvature of the button 68 to conform to.
Fixed to the flanges 44 and 46 are a pair of leaf springs 88 and 99 respectively. They have upturned portions 92 at the ends thereof for finger gripping purposes and engage the wound wire or line for two purposes. The first purpose is to guide the line as it is being played in or played out and the second purpose is to retain the reels 39 and 32 in operative position, so that the gears 26 and 28 are in mesh. When it is desired to utilize only one reel as when paying in or paying out one line to lengthen or shorten the same for line adjustment, the pre-selected spring is lifted andrthe desired reel simply slid axially of its pertinent shaft slightly until the gears are out of contact. Then, the spring is permitted to fall below the outer periphery of the reel by its inherent resiliency, thereby preventing the reel from moving inwardly so that the gears will again become in engagement. The reverse operation takes place in fully assembling the device so that the gears are again enmeshed. Accordingly, it is possible to coordinate the device with v the control surfaces of a model aircraft so that both the aircraft and the device are in proper position while the aircraft is in flight.
In order that the line will not inadvertently become unwound on the reel, a pair of pins 95 and 93 respectively are fixed to the base I and are disposed adjacent each reel. The said pins have reduced center portions in order to allow for maximum movement of the line toward and away from the reel, yet prevent the same from jumping the reel.
While there has been described and illustrated but a preferred form of the invention, it is apparent that variations may be made without departing from the spirit thereof.
Having described the invention, what claimed as new is as follows:
1. In a control device for a tethered attachment, a base having a number of apertures, a reel mounted on each side of said base, a slidable pin carried by one of said reels and disposed in one Of said apertures to prevent rotation of one of said reels, means supported by said base for drivingly connecting said reels including shafts secured to said base, a gear on each of said reels, the gears being enmeshed, and said reels mounted for rotation on said shafts.
2. In a control device for a tethered attachment, a base having a number of apertures, a reel mounted on each side of said base, acontrol member attached to each reel, a slidable pin carried by one of said reels and disposed in one of said apertures to prevent rotation of one of said reels, means supported by said base for drivingly connecting said reels including shafts secured to said base, a gear on each of said reels, the gears -being enmeshed, and said reels mounted for rotation on said shafts, springs carried by said base and engaging said control member on the reels for guiding the control member and for retaining the reels on said shafts;
3. A control device for a tethered attachment comprising, a base having an opening therein,
shafts extending from each side of said base, reels having gears thereon, said reels slidably disposed on said shafts and said gears being enmeshed with each other, means for actuating said reels, and resilient means attached to said base operatively engaging each of said reels for retaining said reels on said base and for guiding a line when it is being played in and played out from said 'reels.
