Abstract

739,274. Connecting branch pipes to mains. COAL INDUSTRY (PATENTS), Ltd. Nov. 27, 1953 [Nov. 27, 1952], No. 30084/52. Class 99 (1). [Also in Group XXII] In a device for fitting branch connections to pipes, the connection 2 has one or more side branches 1, means for securing the connection to a pipe P, and gear means 15, 18, 20, 12 for automatically feeding a drill 7 into the pipe at a rate dependent upon its speed of rotation. The device is used for tapping a high-pressure main for fire fighting. A collar 22 retains the drill if the feed mechanism is removed. The saddles for securing the connection to the pipe may be clamped by bolts 4 or by chains provided with screwed tensioning bolts. A double packing washer 5, 27, Fig. 4, enables a water-tight connection to be made to pipes varying in diameter. An emergency set may be packed in a case comprising the device, a hydrant, a wrench, a handle, a selection of saddles and pipediameter gauges.
