Ginter, Bryan, Ohio, assign'or to The‘ Aro Equipment Corporation, Bryan, Ohio, a cor-7 poration of Ohio Application April 26, 1944-, Serial No. 532,741 1 Claim. (Cl. 285-—169) 1 2 My present invention relates to a coupler par ticularly adapted for coaction with a jaw coupler of the kind that becomes disconnected from a lubricant reception ?tting when swung to an an tube I4 for coaction of the jaws I3b of the coupler ‘ I3 therewith and the sleeve I5 is of such size as to readily slide over the coupler I2 as shown in Fig. 1. gular position relative thereto. One object of the invention is to provide such The tube I4 has a ring-like stop ?ange I8 for coaction with a stop ?ange I9 of the sleeve I5. Another ring-like ?ange 25 is provided on the a coupler with a sleeve that slides over the jaw coupler to prevent it from moving to such angular sleeve I4 adjacent the left hand end thereof. A position during lubricating operations. spring 2| is interposed between the ?anges I9 and Another object is to provide a spring means to 10 20 and biasing the sleeve I5 to slide to the posi automatically extend the sleeve to a position sur tion of Fig. 1 with the flange I9 engaging the rounding the jaw coupler so as to retain it in align ?ange I8. The inner diameter of the ?ange I9 and the periphery of the ?ange 20 serve to guide ment with my coupler. Still another object is to provide the sleeve the sleeve I5 in its sliding movement. As illus slidably mounted so that it can be manually re tracted against the action of the spring to a posi tion where it does not surround the jaw coupler and thereby permits the jaw coupler to be dis connected by swinging it to a non-aligned posi 15 trated on the drawing, the coupler I 3 may be con nected with a lubricant line such as a pipe 22 and a ?exible metal hose 23 through which lubricant under high pressure is supplied to the coupler I3. It will be readily understood that the sleeve I5 20 is freely slidable on the tube I4 with minimum tion. With these and other objects in view, my inven friction on account of the fact that the stop tion consists in the construction, arrangement and ?anges I8 and 20 on the tube I4 adjacent each combination of the various parts of my device end and the movement limiting ?ange I9' on the whereby the objects contemplated are attained, sleeve form bearings which space the sleeve from as hereinafter more fully set forth, pointed out 25 the tube and maintain the sleeve and tube in con in my claims and illustrated in the accompanying centric relation. Further the bore in the rear end drawing, wherein: of the sleeve is enlarged so that it houses the coil Fig. 1 is a sectional view through a coupler em spring 2I which normally maintains the sleeve bodying my present invention, showing it con in extended position, the flange on the rear end nected with a lubricant reception ?tting of a bear of the tube being of a larger size to snugly be re ing at one end and showing a jaw coupler con ceived in the enlarged bore of the sleeve. nected to it at the other end. Practical operation Fig. 2 is a similar sectional view showing my coupler adjusted to a position for permitting dis— connection of a jaw coupler; and Fig. 3 is a sectional view on the line 3—3 of Fig. 1. In the operation of my coupler, the jaw coupler I3 may be positioned on the headed ?tting I 'I while the sleeve I5 is in the position of Fig. 1 or, if the sleeve is in the way, it can be manually pushed back to the position of Fig. 2 during the On the accompanying drawing, I have used the connecting operation. The sleeve I5, if it has reference numeral Ill to indicate a bearing into which the usual headed lubricant reception ?t 40 been pushed back, will automatically assume the position of Fig. 1 when it is released providing ting is screwed. At I3 a jaw coupler is shown of the jaw coupler I3 is aligned with the sleeve. the kind for instance in Neilson Patent No. 2,263, Thereafter the jaw coupler cannot swing as to 850, and this coupler ordinarily has its jaw end the position of Fig, 2 during the lubricating oper connected with the lubricant reception ?tting I2. In some instances, however, the ?tting I2 is not 45 ation. When it is swung to the position of Fig. 2, the jaws disengage the ball head of the ?tting I1 so positioned as to permit the jaw coupler I3 to and for that reason'it is necessary to keep I3 enact therewith and an intermediate coupler is aligned with I4 for proper connection of the parts necessary, While lubrication is in process. The operator My present invention contemplates such an intermediate coupler and includes as its essential 50 usually needs both hands for the lubricating oper ation and cannot hold the jaw coupler I 3 in align parts a tube I4, a sleeve I5, a nipple I6 and a cou ment and therefore the sleeve I5 accomplishes pler I3a. The coupler I3a is a jaw coupler of the this desirable purpose. The operator is then free same type shown at I3 and the nipple I6 serves merely as a connection between I4 and I3a. A lubricant reception ?tting I1 is screwed into the to operate a, lever gun or other lubricating device supplying lubricant to the hose 23. 2,404,052 3 4 After the lubricating operation the sleeve I5 swinging it into position out of alignment there may be pushed to the position of Fig. 2 and thus permit the jaw coupler I3 to be swung sidewise or out of alignment with the tube M for discon meeting it from the ?tting H. The coupler l3a-— with, a sleeve on said tube slidable between re Ill-I5 may then be disconnected from the ?t ting I2. Some changes may be made in the construction tracted and extended positions, a stop ?ange on said tube adjacent each end, a movement limiting flange on the sleeve between the stop ?anges on the tube, the rear end of the sleeve having a larger bore than the forward end of the sleeve and the ?anges on the tube having external diameters cor responding to the portions of the sleeve in which and arrangement of the parts of my coupler with out departing from the real spirit and purpose of 10 they are located and forming bearings serving to my invention, and it is my intention to cover by ' space the sleeve from the tube and maintain the tube and sleeve in concentric relation, the ?ange my claims any modi?ed forms of structure or use of mechanical equivalents which may be reason on the sleeve likewise assisting the spacing of the sleeve from the tube and serving as a bearing be ably included within their scope without sacri?c '15 tween the sleeve and tube, and a coil spring con ing any of the advantages thereof. ?ned in the enlarged bore of the sleeve about the I claim as my invention: tube and between the ?ange on the tube and that A coupler for high pressure lubricant lines com of the sleeve and normally maintaining the sleeve prising a tube terminating in a headed ?tting with in extended position. which a jaw coupler is adapted to be engaged when in alignment therewith,and disengaged by 20 CHARLES W.
