The object of myinvention is to. provide a novel mechanism for use in, detachably coupling a receptacle with a male unit; for applications wherein there may be considerable stress between the parts. An example of such application is the attachment; of interchangeable barrels to a breech block. for; rapid-fir guns where it is necessary to Changebarrels in aminirnum of time.

Still another object is to, provide a coupling device which. has few parts. and is rugged and reliable.
Thev following is a, description or my invention, referencebeing made t the accompanying drawing in which:
Figure 1 is. a vertical cross, section of my device showing the receptacle: and male matching unit in partially engagedrelation.
Figure 2 is, a vertical cross. section showing the members. in fully. engaged and locked relation.
Figure. 3. is. a cross sectional view showing the atc i m mb r andna n in p p n- Figui e 4 is a. view similar to that of Figure 3 but showing the latching members in, engaged position.
Figure 5, is a longitudinal, view of the male or plug unit,
Figure fiis a prospective view of the upper end of the receptacle-unit.
Figure 7 is a view showing a modified form of locking device for preventing the accidental uncoupling of. the device.
In the drawing the numeral I designates a receptacle unit which may be a breecheblock of a gun or lathe chuck or collet or any receptacle designed to receive a plug member 2 which may be a. gun barrel, or lathe tool, etc. The element 2, has a reduced portion extendingbetween the end, of the element and shoulder 3. At a distance from 3 on the element 2, I provide a groove for purposes presently to become apparent.
At he: pp r end of he, main. od of t eceptacle: l, I; provide. a plurality of arcuate seats 3. n: w ich-.1. rest thev u cnums. 1. of lat h incm:-
bers t. The latch members are retained in place by a member Ill arranged to be secured to the upper portion of the receptacle main body I. On the inner surface of the element I0, I provide a circumferential arcuate reces 9 to cooperate with the arcuate recesses 8 to complete the bearings for the fulcrums I of the latch members 6. I have provided the means whereby the latch members. are Withdrawn and held out of the passageway of the plug, element When the same is being telescoped into engagement with the receptacle. To this end I, have provided the following structure.
R ferr n part c larly to Fi ures 2, 3, n it is seen that a slot H is provided in the base portion. or each oi the latching elements 6 for receiving a resilient snap element I2. In the embodiments shown herein and for purposes of explanation, the receptacle and plug elements are shown as round although they need not have this, geometric configuration. The snap element [2 is in the form of an annular disc which has two conditions of stability which are convex conditions in opposite directions of a plane passing through the outer periphery thereof. It is apparent that the combination of the latching members, 6 and the snap ring l2 provides an assembly wherein, the latching elements are strongly urged either into latched position or unlatched position.
The snap ring is most easily fabricated from a flat sheet by a punching operation in which. the inner periphery of the ring is stretched; or the ring may be punched out flat and the inner p r phery o th r n s r t h as y r m s- The sub-assembly consisting of the latching elements 6 with, the snap ring l2 are assembled in the receptacle unit as shown in Figures 1 and 2,
Referring to Figure 1, it will be noted. that the inner portionv of the snap ring extends inwardly of the base portion of the latching. elements whereby insertion of the, plug unit permits the lower shoulder of portion 3 to engage the same. Further, urging of; the plug, member toward the receptacle against theresistanceof the snap ring causes the, snanringto pass to. a, position of dead center in which. the, snap ring is planar in form. The further engaging of the plug with the receptacle is thenassistedby the action of the snap ring which snaps the latching elements 6. inward and downward. with the surface 5 of the latching elements 6. engaging the upper shoulder 4 of the plug element 2. The receptacle, the plug, and the, latching, elements. now have the position shown; in: Figure 2 with they latching elements firmly engaging the plug, and the snap ring is in lower convex position.
In some applications of the present invention, it is desirable to provide close continuity between the receptacle and male unit. To this end, I provide a cylindrical recess having a base IS in the receptacle and an extension portion having an 'end H on the male portion. The lengths of these portions are proportioned so that they are either in contiguous relation or admit of a resilient gasket when the male member and receptacle are in engaged relation.
In some cases, particularly in guns, it is desirable to provide means for preventing accidental opening of the latch elements due to recoil or other shock. In such cases I provide a lock sleeve IS. The inner surface of this sleeve is telescopically supported on the plug element 2. A portion of the interior of the lock sleeve is removed to provide an annular recess to accommodate the outer surfaces of the latching elements when in latched position as shown in Figure 2. Provision is made for the manipulation of the locking sleeve into locked or unlocked position by finger grips l9.
To prevent the accidental displacement of the lock sleeve under conditions of vibration or recoil, a plunger It is inwardly urged by spring 26 and is slidably supported in a transverse aperture in the element ill of the receptacle i.
outwardly extending annular flange 13 is pro- I vided at the lower end of the locking sleeve for engagement with the spring-pressed plunger I4.
An alternative form of locking sleeve is contemplated and shown in Figure '7. In this embodiment, I provide a plurality of bent lugs having circumferential portions 2| spaced from the end 26 of the element Ill by longitudinal portions 22 at one end thereof. The lower surfaces of the lugs 2i together with the end of the element it], provide circumferential slots for the reception of ears 23 which may be formed on the end or intermediate the ends cf lock sleeve l8. In this case, also, I provide means to prevent the accidental disengagement of the locked sleeve from locked position in the form of spring elements 2 1 having upstruck portions 25.
It is therefore seen that I have devised a detachahle coupling device which is rugged, and at the same time, simple and easy to use, and which can be readily incorporated in devices of plug and receptacle form.
