MEANS AND CONSTRUCTION FOR INSERTING FITTINGS UNDER PRESSURE.

SPECIFICATION forming part of Letters Patent No. 571,07*?, dated November 10, 1896. Application filed June 6, 1896. Serial No. 594,504. (No model.)

Next a stop 16 is introduced into the now open nipple of the cock, and a cap 17, perforated to admit the shank 1S of the stop, is screwed onto the nipple of the cock, taking the place of the removed union 11 and closing again the open end of the cock. (See Fig. 2.) A stuffing-box 1.) may be provided where the shank passes through the cap. XVith the parts in this condition the cock may now be readily opened, because the escape of water is prevented by cap 17. The cock being opened, stop 16 is now pushed through the open passage-way 15 and put in engagement with the inner end of the opposite coupling, closing the same, as shown in Fig. 3. For the purpose of such engagement the stop is threaded externally and fits the internal thread at the inner end of this opposite coupling. A suitable removable handle or handwheel 26 is provided to operate and turn the stop. This connection, which thus shuts oit the water, being made, the whole cock may now readily be taken ofi' after the union holding it yet at the other side is unscrewed, because stop 16 closes the pipe for the time being and prevents the water from pouring out. This leaves the parts as shown in Fig. 4L. For replacing the new cock the procedure is similar, only that its different steps are performed in converse order. Thus the new cock is slipped over the stop and connected to the closed coupling. Cap 17 havin g been taken off from the removed cock, is then passed in over shank 1S of the stop, and the open nipple of the new cock is closed, putting the parts again in position, as shown in Fig. 3. This permits withdrawal of stop 16 from the coupling, which is kept closed until then, such withdrawal being sufficient to clear the passage-way of the cock and permit the latter itself to be closed. Cap 17 and stop 16 are now entirely removed, after which the end of the other pipe is bent back into position again and connected by the union, as may be readily understood.

For larger pipes or where the pressure is considerable a hooked brace 24 may be provided, which is engaged with projections 25 on cap 17 and has a screw-shank 26 seated in the end 27. By means of a sliding sleeve 2S it is connected to the end of shank 1S of the stop, and the latter may now be readily advanced against the pressure and into the screw-threaded coupling.

As will be seen, time, work, and expenses are considerably reduced, no solder joints are required, no leaden pipes need to be cut out, and the inconveniences and disturbances resulting from turning off the water are limited to the one pipe alone.

Under certain conditions and when no leaden pipe is used couplings 9 might represent simply the ends of the pipes themselves.

HavingV described my invention, I claim as new 1. In a stop-fitting adapted to be applied under pressure and detachably connected to the pipe by unions and couplings, a stop 16 adapted to be passed through the passageway of the stop-iitting after the same is rendered accessible by disconnection from the pipe at one side and capable of closing the open end of the pipe or coupling at the other side and a cap to close the disconnected end of the stop-fitting.

2..An implement 'for connecting stop-iittings to pipes while charged and where such fittings are detachably connected to the pipe by couplings or otherwise, such implement consisting of a stop 16 carried by a shank 18 and a cap 17 both adapted to be temporarily connected, the first for the purpose of closing the open end of the pipe, the other to close the open end of the stop-tting and all to be applied in the manner described.

In a construction to insert iittings in pipes While charged, the combination of a cock or similar stop-iitting detachably connected toits pipe by couplings 9 and unions 1l, the inner ends of the couplings being screwthreaded, a stop 16 threaded to fit the threaded end of the couplings and adapted to be passed through the passage-way controlled by the stop-iitting after the same is disconnected at one side and thus opened for access, a cap 17 to temporarily close the open end of the stop-'fitting and a shank on stop 16 and passl ing through cap 17 to manipulate it.

4c. An implement for inserting stop-fittings into pipes while charged and where such {ittin gs are detachably connected to the pipe by couplings or otherwise, such implement consisting of a stop 16 carried by a shank 18 and screw-threaded to iit the correspondinglythreaded end of one of the permanently-connected couplings for the purpose of closing thereby the open pipe, and a cap 17 fitted to close the open end of the stop-iitting while stop 16 is being inserted to close the open end of the pipe and a shank passin through cap 17 to manipulate stop 16.

5. An implement for inserting stop-iittings into pipes while charged and where such iittin gs are detachably connected to the pipe by couplings or otherwise, such implement consisting ot' a stop 16 carried by a shank 1S, a cap 17, having projections 25, fitted to close the open end of the stop-tting while stop 16 is introduced, a shank 1S on stop 16 passing through cap 17 a brace 21 adapted to be temporarily connected to projections 25 on cap 1.7 and a screw-shank 26 supported in the end of brace 24 and adapted for connection to shank 1S for the purpose of manipulating stop 16.

In testimony whereof I hereunto affix my signature in presence of two witnesses.
