' a coupling which will permit the ready remova-l of the meter for the purpose of-in spection or repair, without the necessityof detaching any part of the coupling fo'r the ipurposc, and which will alsoi'acilitate the connecting of the .supplypipe with lthe service-pipe temporarily during such repairs or inspection, whereby, except fora ew .minutes there will be no interruption of the supply of water to a dwelling.

W ith the aboveand other objects in view, as will appear as the nature of the invention 'is better umleistiiiod, the same consists ofthe l vnovel construction and combination of parts `of a water meter coupling, as will be hereinafter fully described and claimed.

In the accompanying drawing, forming a part of this' specification, and in which like characters oi reference indicate corresponding parts: Figure 1 is a view in ele` vation artlv in lsection dis )lavino a water 3 .l u C1 meter coupling embodying the features of the present invention. Fig. Q is a longitudinal l section through the 'forni ot coupler shown to the leftoi Fig. 1. laligf is a side elevation of the bridge pipe.

Referring to the drawings, and t'olfigs. 1 and 2 thereof, M designates a water m'eter of any preferred type, and provided on opposite sides with threaded teats "in and'mz, one of which is connected with a pipe 1 that communicates through a valve :2 with a pipe 3 leading from the main, and the other of which is engaged by a slip joint or sliding nipple 4 that forms one of the featuresv of novelty of the presentl invention. As shown in Fig: 2, that end ofthe nipple that engages the tcat m is enlarged to constitute 'a coupling nut 5 the periphery of which is pro` vided with wrench faces t'.b v which the' nipple may'readily be detached by au ordinary wrench when desired toy remove the meter. `The nipple tits in a coupling niember 7 provided with wrench faces 8.

end of the coupling :into Vwhich the nipple projects is provided with male threads that are engaged by a stutiin box 9 provided withwrencli faces-10. T iis stuffing box is provided with anV inturncd shoulder`l1, b'- tween which and the end of the coupling member is interposed a packin ring 120i any suitable material, such as eather, rubber, asbestos, hemp or the like, and which vwhen compressed bythe shitting box will be caused to inipinge against theouter wall of the nipple, and' thus secure a water-tight joint. The end or' the coupling vmember opposite that engaged Aby "the stufiing box is Iprovided with female threads, and these are engaged by. the'xservice-pipe 13 that leads to the house. l

iVith the form of the invention above described, when it is ldesired to remove the meter, for the purpose of inspection or repair, or to substitute another meter, thernnt 14- tliat secures the pipe I to the teat 111-2 is Y loosened, the valve being first operated to -eut oft' the supplyv of water'to the meter.-

The sliding nipple 'et is then disconnected Yfrom the teatm., anda short bridge section of pipe 15 is substituted 'for the meter and ene'ages,.res ectively, with the nut- 14: and

sliding nipp e 6, as shown in Fig. 1.- The valve 'l isthen o cned, thereby permitting water to pass to tie house. A

It will'be. seen from the foregoing description that 'by the .provision of the sliding nipple 4, that the detaehi'ncnt of a water meter from tlie'feed and service-pipes may readily be effected, without inconvenience to the' householder, and further that different sized meters may beinstalled-without requiring any change whatever in the structural arrangement of the usual' coupling, eonsistnier of the kpipe 1 and nut. 14, and the Ilavingthis fully described the invention what is claimed is In a device of the class described. a meter provided with oppositely disposed, threaded teats; a supply pipe; a rigid coupling uniting the supply )ipe and one teat; a service pipe; a nipple enlarged at one end to form a coupling riut to engage the other of said teats, the nipple bein of less diameter than the service pipe andbeing arranged to be received within the service pipe; a coupling member threaded to engage the exteriorof the service pipe and having a reduced neck nnprofecl coupling constituting the subjectmatter of thel present invention.

` felation,l the end adapted to receive 'closely an of the nipp1e,andto: s ace. thenipple against contact with the wa s of the service pipe; a stuiin box threaded :to

` coupling and the coupling nut are disen- 10 gafred from the tents.4
