Specification of Letters Patent.

Patented June 6, 1916.

Application filed July 9, 1915. Serial No. 38,860.

To all whom it may concern: I

Be it known that I, JULEs P. Mn'rzenn, a citizen of the United States, and a resident of Carlstadt, in the county of Bergen and State of New Jersey, have invented a new and Improved Coupling, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved coupling more especially designed for use on the injector of a locomotive and arranged to enable the engineer to quickly couple or uncouple the steam supply pipe and the injector.

In order to produce the desired result, use is made of a coupling member provided with an internal retaining flange and a locking ring provided on its peripheral face with spaced annular shoulders forming a groove between them, the said flange extending into the said peripheral groove and being straddled by the said shoulders, the said locking ring being made in sections, of which one is the key section. Use isalso made of a manually controlled external locking device held on the coupling member and engaging the key section.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference inclicate corresponding parts in all the views.

Figure 1 is a longitudinal central section of the coupling as applied and connecting an injector with its steam supply pipe, the section being on the line 1-1 of Fig. 2; Fig. 2 is a cross section of the same on the line 22 of Fig. 1; Fig. 3 is a longitudinal central section of a modified form of the coupling; Fig. 4 is a similar view of another modified form of the coupling; Fig. 5 is a similar view of another modified form of the coupling; Fig. 6 is a face view of a modified form of the key section of the locking ring; Fig. 7 is a plan view of the same with part shown in section; Fig. 8 is a longitudinal central section of the coupling provided with a modified form of locking device for the key section of the locking ring; Fig. 9 is a cross section of the same on the line 9-9 of Fig. 8; Fig. 10 .is a longitudinal central sect1on of the coupling provided with another modified form of locking device for the key sect1on; Fig. 11 is a cross section of the same on the line 1111 of Fig. 10; and Fig. 12 is a face view of the key section of the coupling shown in Figs. 10 and 11.

In locomotive service the steam connections and couplings for same are of primary importance and this is particularly so in reference to the injectors and their pipe connections. The present invention permits of making repairs in case of mishap to the equipment in the quickest possible time. In

case of the breaking of brazed or other joints of locomotive connections, these parts have to be renewed. This is accomplished with great difiiculty with ordinary couplings, requiring in some cases the cutting of pipe and rebrazing of sleeves, frequently.

making it impossible to do the repairs on the road and requiring the train to be taken to the round house, thus subjecting the trains to great delay.

In the present improvement, the novel construction of parts presents the best possible means of disconnecting and connecting the parts, the improvement providing reversible parts, so that it is impossible to put them in wrong position, and the coupling or renewal of the coupling nut can be accomplished in the shortest possible time. In former devices of this class, some are complicated, requiring special tools, and others are diflicult to get at, and the parts used have to beselected, as they are right and left parts, and in such cases it is not really certain that the parts are properly assembled, or in proper alinement or that one part is not binding upon the other. This is especially the case when the work has to be done not only in the quickest time, but while the parts may be hot and the repairs may have to be made at night. In the present invention the engineer can couple or uncouple by merely feeling the parts and when the parts are put together a perfect joint is insured.

The coupling illustrated in Figs. 1 and 2 is shown applied to a locomotive injector for coupling the steam pipe A to the threaded part or nipple B of the injector B. The pipe A, which is usually made of copper, is provided with a coupling head A in the form of a sleeve, soldered, brazed or otherwise fastened to the end of the pipe A, and the said coupling head is provided at its forward end with an annular shoulder A adapted to abut against the end of the nipple B, the contacting parts being preferably beveled to form a tight joint, as plainly indicated in Fig. 1. On the nipple B screws a coupling nut C provided at its outer end with an inwardly extending annular flange C straddled by spaced annular shoulders D and D formed on the peripheral face of a locking ring D fitting onto the head A of the pipe A and adapted to abut against the shoulder A", as plainly indicated in Fig. 1. It is understood that the flanges D and D form between them a groove into which extends the flange C so that when the nut C is screwed up on the nipple D the locking ring D firmly draws the head A in engagement with the nipple B to properly couple the members A and B together. The locking ring D is made in sections, preferably, a key section. D and two side sections D and D, as plainly indicated in Fig. 2. By constructing the locking ring D in the manner described, the section can be readily removed from the nut C on unscrewing the latter and moving the ring beyond the coupling head A onto the pipe A. It is understood that when the nut C and the ring D reach this position they can be readily moved into eccentric position relatively to the pipe A to allow of moving the key section D from the flange C, after which the side sections D*, D can also be conveniently removed from the flange C. It will be noticed that the said sections D, D are interchangeably reversible and hence the engineer is enabled to quickly place the same in position after repairs are made and the pipe is again to be coupled to the injector. The key section D is reversible so that'it can be placed quickly and conveniently in position to hold the side sections D, D in place and to allow of engaging the ring with the flange C. After the parts are assembled the locking ring can be readily slipped onto the head A and on screwing up the nut 0 causes a re-coupling of the members A and B, as previously explained. The flange C is provided with a bevel C at its outer face to permit of conveniently engaging the sections D D and D with the flange C when assembling the parts as above explained. In order to prevent accidental dropping out of the key section D on uncoupling the parts, use is made of a retaining or locking device E, preferably in the form of a spring secured to the peripheral face of the coupling nut C and engaging with its free end a slot or groove D formed on each side of the key section D It is understood that by this arrangement the spring E engages the groove D which is outermost at the time.

In the modified form shown in Fig. 3, the pipe A is provided with an integral. head A having a shoulder A onto which fits the ring D engaged by the flange C of the coupling nut C screwing on the nipple B of the injector B. Otherwise, the construction is the same as above described in reference to Figs. 1 and 2.

In the modified form shown in Fig. 4:, the flange C of the coupling nut C is beveled at both the inner and outer sides and the shoulders D and D of the locking nut D are similarly beveled at their inner opposite sides. Qtherwise the construction is similar to that shown in Fig. 3.

In the modified form shown in Fig. 5, the locking ring D has its inner wall rounded olf. Otherwise the structure is practically the same as above described in reference to Figs. 1, 2, 3 and 4c.

The groove D of the key section D instead of being straight as shown in Fig. 2, may be curved, as indicated in Figs. (3 and 7, and the back wall of the groove is preferably slightly indented as at D for engagement by the free end of the spring E to prevent shifting of the locking ring D on the head A of the pipe A.

The locking device E, shown in Figs. 8 and 9, consists of a spring attached to the coupling nut C, and on the free end of the spring is secured a dovetailed tongue E adapted to engage a correspondingly shaped groove D formed in key section D of the locking ring D. It is understood that the dovetailed groove D is on both sides of the key section D to allow of placing the latter in either position on the head A of the pipe A.

In the modified form of the locking device shown in Figs. 10 and 11, the key section D is provided on each side with a groove D", the same as above described in reference to Figs. 8 and 9, and either groove is engaged by a correspondingly shaped block E held on a rod E attached to the coupling nut C. The block E is provided with finger pieces .13 adapted to be taken hold of by the engineer to permit of conveniently moving the block E out of engagement with the dove tail groove D whenever it is desired to uncouple the coupling. A spring E is coiled on the rod E and presses the block E so as to hold the latter normally in engagement with the groove D From the foregoing it will be seen that the coupling shown and described is very simple in construction and its parts can be readily assembled and applied to the members to be coupled together. It will also be noticed that by making the locking ring in sections, of which the side sections are interchangeable and reversible and the key section is reversible, the engineer does not experience any difliculty in assembling the parts in daylight or during the night.

I do not limit myself to theparticular application of the coupling as shown and described, as it is evident that the coupling may be used for coupling other members than those shown and described.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
