BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates primarily to methods for quickly disconnecting driveshafts and couplings from driving and driven flanges with a threaded collar. More particularly, the present invention relates primarily to a method of quickly connecting and disconnecting a Cross-Tooth Propeller Shaft Flange, type T as in International Standard ISO 12667 with a threaded collar. A second embodiment of the present invention relates primarily to a method of quickly connecting and disconnecting a wing bearing style universal joint to a flange with a threaded collar. A third embodiment of the present invention relates to a short couple double wing bearing style universal with a quick disconnect threaded collar on each end. 2. General Background of the Invention
Typical means for attaching a coupling or universal joint to a driving or driven flange includes a plurality of bolts that fixedly attach the coupling or universal joint flange face to the face of the driving and driven flanges. Wing bearing and half-round universal joint styles employ a plurality of bolts to secure cross trunnion and bearing assemblies to driving yoke and flange components. In many driveline applications, 360° access is not available to properly remove and install all flange bolts. The present invention provides an improved method of attaching a coupling or universal joint to a driving or driven flange by providing a single locking collar that can fixedly secure a coupling or universal joint component to a driving or driven flange. By providing a collar with a shoulder that mates with a corresponding shoulder on the coupling or universal joint and a threaded section within the collar that mates with a corresponding threaded section on the of the flange, then the coupling or universal joint can then be attached to the flange in a secure manner. This method of attaching a coupling or universal joint to a flange is advantageous over other means because proper torque can be applied to the collar from any position where access is available. Other attachment means can have bolts that can only be accessed from the opposite side of the shaft making proper installation difficult or impossible in confined spaces.
The components of the present invention preferably employ a grooved flange face having a cross-tooth propeller shaft flange, type T as in International Standard ISO 12667, which mates with corresponding teeth on the coupling or universal joint. A collar that has a shoulder and a threaded section whereby the collar can be placed over the coupling or universal joint flange and threaded onto the mating driving or driven flange therein securing the coupling or universal joint to the flange.

In a preferred embodiment of the present invention, a collar is used to attach a Cornay® (preferably) or other universal or constant velocity joint flange to a driving or driven flange wherein each flange face has a series of cross toothed grooves that mate with corresponding toothed grooves on the mating flange. This embodiment of the present invention is advantageous over bolting style flanges because only a few turns of the collar will securely attach one flange to the other making the processing of connecting and disconnecting a driveshaft quick and easy.

DETAILED DESCRIPTION OF THE INVENTION
Driveshaft Coupling 100 includes cross toothed driving flange 101, collar 103, universal joint or coupling cross toothed flange yoke 105, retaining and locking ring 102 and retaining ring 104.
Although a Cornay® constant velocity joint 10 (of the type shown in Cornay Company US Patent No. 6,773,353, and commercially available from Cornay Company as model no. CVX-30) is shown in this example of the preferred embodiment, other types of Cardan, Hooks, Double Cardan, Rzeppa, Tripot and various other types of universal joints, constant velocity joints, and flexible and rigid driveshaft couplings can also employ this attachment means.
Driveshaft Coupling 100, shown in Figures 1 -6, can be assembled by the following method: First: Assemble collar 103 onto cross-toothed coupling flange 105 of coupling. Retaining ring 104 is installed over cross-toothed coupling flange 105 by spreading open the coils of the retaining ring 104 and feeding the retaining ring 104 over and behind the face of flange 105 of constant velocity joint or coupling 1 16 and feeding the coils around until the retaining ring 104 is on the side of the face of flange 105 opposite to cross teeth 109. Collar 103 is then inserted over cross- toothed coupling flange 105 so that retaining ring 104 can be installed into groove 110 of collar 103.
Second: Assemble retaining and locking ring 102 onto cross-toothed threaded flange 101.
Retaining and locking ring 102 is installed onto cross-toothed threaded flange 101 such that tabs 1 14 engage with grooves 1 11 of cross-toothed threaded flange 101 and retaining and locking ring 102 abuts against shoulder 1 15 of cross-toothed threaded flange 101.
Third: Cross-toothed coupling flange 105 is attached to cross-toothed threaded flange 101.
Flanges 101 and 105 are brought together such that the teeth 109 of cross-toothed coupling flange 105 mates with the teeth 108 of cross-toothed threaded flange 101. Collar 103 is screwed onto cross-toothed threaded flange 101 by the engagement of threads 107 of collar 103 with threads 106 of flange 101.
Fourth: After sufficient torque has been applied to collar 103 to remove all free play then one or more of tabs 1 13 of retaining and locking ring 102 are folded into grooves 112 of collar 103 thereby preventing collar 103 from unscrewing.

Novel features may include:
In reference to the first embodiment (#100).
US Patent No. 4,053,248 discloses a cross tooth flange design that is commercially available and even has an ISO standard. There are boltholes used to couple this flange to a mating flange with teeth.
What is novel about the present invention is that there is a rotatable collar, such as a threaded collar 103, in place of the four bolts to hold the flanges together. The present inventors have not seen a combination of a cross-tooth flange and a rotatable collar, such as a threaded collar. The cross-tooth flange 101 of the present invention has a novel threaded outside diameter and notches to prevent the locking ring 102 from rotating. The threaded collar 103 with external notches and internal retaining ring groove 110 is also believed to be novel. The method of using a locking ring 102 to prevent the threaded collar 103 from unscrewing is believed to be novel as well. The following combination of the assembly which is believed to be novel includes: Cross-tooth flanges 101 and a threaded collar 103 with external notched and internal retaining ring grove 110, and a retaining ring 104, and a locking ring 102.
In reference to the second embodiment (#200):
A standard off-the-shelf wing bearing kit employs four bolts to secure the wing bearing to the input and output yokes of the universal joint. In an embodiment of the present invention, the present inventions have replaced two of the four wing bearings with modified wing bearings that have a clamping shoulder to replace the bolts. What is believed to be novel is a universal joint comprising a wing bearing 203 , 204, 206, 207 with a clamping shoulder 213. Using a threaded collar 202 to secure a wing bearing 203, 204, 206, 207 with a clamping shoulder 213 to a circular wing bearing flange 201 with a threaded outer diameter is believed to be novel. Employing a threaded collar 202 with a thin lip 226 as disclosed herein to be folded into a notch 225 on a wing bearing 203, 204 to prevent unscrewing is believed to be novel. The combination of the assembly which is believed to be novel includes: A universal joint employing a wing bearing 203, 204, 206, 207 with a clamping shoulder 213 , a grooved flange face 201 with threaded outer diameter, and a threaded collar 202 with internal shoulder and external locking systems.
In reference to the third embodiment (# 300):
The present inventors are placing two joints/couplings similar to coupling 200 of the second embodiment back to back by bolting the two together with a wing bearing connecting flange 305. PARTS LIST:
