Y., a cor~ ‘ Application May 4,1937, Serial No. 140,624 5 Claims. (Cl. 285-174) ' vThe present invention relates to hose couplings and more particularly to aquick detachable cou pling for releasably connecting hose lines trans mitting fluids under vacuum or moderate pres mounted in a groove II in the socket in position to bear on the portion 3 of the'nipple when thel coupling is assembled. Releasable locking means for holding the cou-Y pling in assembled relation is provided >in the Various types of quick detachable hose cou plings have been developed and found commer cial vacceptancebut such couplings have in gen eral been more or less specializedl in character 10 in accordance with the type of installation in which they are employed. In particular there is a lack of commercial couplings of this type which are interchangeably adaptable for use with con duits for either vacuum or moderate pressure. It is an object of the present invention to pro vide a novel quick detachable hose coupling which is'simpie and economical in construction and ef iicient and reliable in operation. l ' It is another object to provide such a_ device 20 which is readily operable by very simple manipu lation, requiring no twisting or rotation of any kind. ' ' Another object is to provide such a device which is equally well adapted for use in vacuum lines and in lines carrying moderate positive pressures. Further objects and- advantages will be ap parent from the following description taken in connection with the' accompanying drawing in 30 , ` Fig. l isa side elevation partly in section of a coupling embodying a preferred 4form of'îthe in-` vention; seat >in a longitudinal groove I5 (Fig. 4) in the periphery of the socket and provided with lateral 1y extending portions I6 and I’I adapted to seat in a circumferential- groove I8 in the socket so as to prevent longitudinal withdrawal of the locking .clip from the socket. « A thimble I9 is arranged to bear loosely on the periphery of the socket, having a ñange 2| at its outer end provided with an opening 22 to receive the nipple, and a ñange 23 at its inner end arranged to project dntov a circumferential groove 24 in the periphery of the socket, the width of the groove 24 being sufficiently greater than the thickness of the ñange 23 to permit limited ' . which: form of a spring clip I2 (Fig. 5) having a circular ` opening I3 adapted to embrace the portion 2 of I the nipple and having an extension I4 adapted to ` , l Fig. 2 is an end view .of the same; 3 is a view` similar to Fig. lshowing th longitudinal movement of rthe thimblel on the socket. The thimble thus acts as a retainer to prevent dislodgment of the locking clip I2 from its anchored position on the socket, and longitudinal movement of the thimble to the right Acauses the flange 22 thereof to. engage the portion of the locking clip which embraces the'nipple and straighten it up into a position appro 'mately' at right angles to the axis of the coupli g. The locking clip I2 by reason of its elasticity i biased toward an inclined position wherein its opening I 3 engages and grips the portion 3 of tli'e nipple with a clamping action.v 3 Ul parts in unlocked and partially disassembled re- " lation; _ , l l Fig. 4 is a side elevation of the socket member; and » Fig.` 5 is a detail in perspective of the auto 40 matic locking device. Referring ñrst'to Fig. 1 of the drawing, there is illustrated a spud or nipple I having a'cylin drical surface 2 adapted to enter a socketmern' ber, and- a second cylindrical .surface 3 of smaller 4 diameter adjacent its end, the step „between the two surfaces being defined by a beveled shoulder I. The end of the nipple is preferably beveled as indicated at 5 to facilitate entry into the socket. 50 v ' y " A socket member 8 is provided with an interior cylindrical surface 1 adapted to loosely fit the por-' tion 2 of the nipple and a second cylindrical sur face 8 adapted to receive the portion 3 of the nipple. Packing means illustrated in the form of 55 a ring 9 >oi' rubber or other suitable material is> In the operation of the device, introduction of the nipple into the socket as illustrated in Fig. 3 causes the locking clip I2 to straighten up sufiì ciently to slide on the portion 2 of'the nipple, whereupon the cylindrical portions of the‘fnipple enter the corresponding portions of the socket, with the packing II bearing snugiy on the por tion.3 of the nipple» Withdrawal of the nipple from the socket is then prevented by the clamp' ing engagement of the locking member I2 there on, which engagement isI tightened by such efforts. r ' - - - When it is desired to release the coupling, it is merely necessary to apply :longitudinal pres sure to the thimble I9, preferably by pressure` 50 on the outer ña'nge 2I thereof. The flange 2l Vthereupon engages the locking portion of the clip I2, causing-it to straighten up and release thenipple, whereupon the latter may be readily ’ withdrawn. 55 ’ vsaumur?? ’ Although but one embodiment of the invention loosely in said socket, a locking clip anchored to the socket and gripping the nipple, and a be'understood that other embodiments are pos- i' thimble surrounding the socket,Y retaining the sible and various changes may be made in the locking` ‘clip’ in its anchorage and slidable on design and arrangement of the parts without the socket to engage and release the gripping has been shown nand described- in detail, it will ‘ departing from the spirit of the invention as de portion of the clip. ñned in ¿the claims appended hereto. *s ' , 4 .In.a hose coupling, a socket, a nipple hav ing a cylindrical portion ñtting loosely in said socket, a locking clip anchoîred to the socket lnipple member" adapted to fltgloosely ltlierein, and having avportion embracing the cylindrical 10 ?means for packing the joint gtherebetween, a portion of the nipple and tiltable to? grip the locking element anchored to one coupling mem same, and a thimblë surrounding the socket. ber having a portion ìoosely iìtting the otherY retaining the; locking clip in its anchorage and Whatïis claimed is: . 1.
