DEVICE FOR REMOVING FERRULES AND FOR INSERTING PLUGS IN WATER-MAINS UNDER PRESSURE.

Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed June 10, 1905. Serial No. 264,584.

To all whom it may concern.-

Be it known that we, WILLIAM B. DALEY and WINDSOR E. RICHARDS, citizens of the United States, and residents of Cleveland, county of-Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Devices for Removing Ferrules and for Inserting Plugs in Water-Mains Under Pressure, of which we hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention has for its objects to provide means for removing a side water connection from a Water-main and for afterward plugging the opening in the main without overflow of the water from the opening and without loss of time required for closing the valves in the main while the opening is being closed.

Heretofore much loss of time has been occasioned, and the use of water has been suspended in the district supplied by the main whenever plugging connections have been removed. Hence the loss of a great amount of water and inconvenience occasioned thereby should be prevented. The shutting off of a water-supply occasioned by closing a watermain often results in shutting down factories containing boilers, shuts off all house connections in that district, and also causes risk in case of fire. With this improved device, however, the escape of water is prevented, and

also the time consumed in withdrawing the connections and placing the plug in the vacated hole in the main is saved, and the objectionable feature of loss of water-supply to the cut-off district is avoided.

To accomplish these objects. we employ a hollow casing adapted to be secured over the opening in the main. Within this casing is pivoted a lever device for withdrawing the pipe connections from the main, and a screwpressure device is also provided to insert and drive home the plug. This casing is watertight when closed, but is provided with a handho'le opening for access to the interior parts.-

The invention also comprises a device for guiding the screw and plug, so as to center the plug with the opening before the casing is closed, and in the various features of construction and operation of parts, as hereinafter described, shown in the accompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical central section of the device, showing the main in transverse section and illustrating in dotted lines the movements of the lever device for withdrawing the pipe connection and of the plugging-screw. The guiding-sleeve and its manner of centering the plugging-screw with the opening in the main is also shown in its place in vertical section. Fig. 2 is a plan view of the device. Fig. 3 is a perspective view of the sleeve-guide for the plugging-screw.

In the views. 1 is the water-main, which is provided with an opening 2 into which the connection or ferrule 3 of a lead pipe 4: is secured.

Before placing the machine over the opening a short section of the lead tube is flattened and cut off at 5, leaving it attached to the ferrule or connection with the main, which is driven into the opening. A rubber gasket 7 is placed about the opening, and the saddle 8, having an opening 6, is placed thereon. The bottom opening 9 of the casing O is then placed over the opening in the main, a gasket G making a tight joint. The centering-sleeve 10, which is separable into two halves, is then placed about the ferrule of the lead pipe and brought into exact line with the plug 11 and plugging-screw spindle 12 above, so that the plug will enter the opening when the screw is lowered. The spindle and ferrule are centered by clamping ends of the sleeve 10 tightly upon them until they are in exact line by means of bolt 28. The screw 12 passes through a nut 13 at the top of the casing and the nut is rotated by means of the hand-wheel 14, a stuffing-box B in the wall of the casing preventing leakage about the screw-spindle. spindle 12 is centered in relation to the nozzle of the lead pipe the machine is attached rigidly to the main by means of chains 15 and bolts 16. The guiding-sleeve 10 is then unclamped and removed through the opening 17 in the side of the casing, and a hook 18 upon the lever 19, pivoted at 20 in the casing, is clamped about the ferrule. The ferrule of the lead pipe is then loosened by tapping it with a hammer, and it is held from. rising by a second person holding the lever 22, which is outside of the machine and is attached to the pivot-shaft 20. This prevents the water from issuing under pressure until the side opening in the casing is closed. The cover 23 is then bolted tightly in place, thus sealing the casing. The outside lever is then raised, lifting the ferrule from the opening in the As soon as the screw- TIO main, and, if necessary, bending the short end of the pipe, which is flexible and will not afford much resistance. The nozzle is lifted far enough to take it out of the path of the plug above. The next step in the use of the machine is to lower the screw by means of the hand-wheel upon the nut until the plug enters the opening in the main and to force it thereby tightly into place. To. be certain that no leak remains before removing the screw, the small cock 25 is turned and the pressure in the casing relieved. If no further pressure is found, the plugging has been successful. The machine can then be removed from the main for further use, and the plug is detached from the spindle, a pin P being a simple fastening device therefor.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In a device adapted to operate as set forth upon a water-main having an opening, and a pipe connection secured therein, in combination instrumentalities for withdrawing said connection and for inserting a plug in said opening, and a water-tight casing inclosing the inner parts of said instrumentalities, substantially as described.

2. In a device adapted to operate in the manner set forth upon a main provided with an opening, and the ferrule connection of a pipe inserted therein, in combination a watertight casing provided with an openingadapted to register with the opening in the main, and through which the ferrule projects, and with a hand-hole and cover, means for securing said casing to the said main, a lever device operatable from the exterior of the casing, and provided with a device for engaging the said ferrule and by means of which it is detached. a plug and pressure-screw in the easing, a nut upon said screw arranged to lower the same and to insert said plug into said opening in the main, and a centering device for said screw and plug, substantially as described.
