    • 10,111. Gillespie, R. A. May 4. Clip and sleeve joints; cotcplings, attaching pipes to.-Relates to couplings for uniting pipes with plain ends in gas, water, or other mains. The sleeve 3 is fitted over the pipe ends, and is provided with stuffing-boxes at each end in which the rubber packing-rings 5 are compressed by the glands 4. The bottom of the stuffing-boxes . is formed with a double bevel 6, 7, the packing-ring being formed similarly, so that the ridge 8 is formed for holding the packing-ring. The gland 4 is provided with recesses into which the dogs 17 are fitted, and projections on the dogs are forced into the pipes by means of the transverse wedges 20 ; longitudinal stresses on the coupling force the dogs further into the pipe. The glands are first brought into position by temporary bolts 22 and the wedges are then inserted. A modification is described in which the dogs are dispensed with and the gland is serrated for engaging the wedges, and in another modification, the sleeve is not provided with a stuffing-box, but the packing-rings are forced against the ends of the sleeve by means of rings at each end connected together by bolts.
