ent quip! sed Portable Saw Rig for Use in Ship Yards HE vital importance’ which wooden ships have assumed in aiding this country in successfully prosecuting the war, has led to a strong demand for woodworking equipment. This demand has been growing steadily as new yards have been organized or projected, and old yards expanded. In addition, the large number of steel ships under construction has caused a wider use of woodworking equipment in finish- ing cabins, decks, etc. 5 The C. H. & E. Mfg. Co., Milwaukee, Wis., has been manufacturing for some time, a portable saw rig especially adapted for work in ship yards. This outfit is a complete portable woodwork- ing mill, self-contained and ready to operate anywhere. It is designed also as a shop tool to take the place of separate machines for the different kinds of mill work. Four operations can be carried on simultaneously. Each attach- ment is said to have as much capacity and is said to do as accurate work as an independent machine. The rigs are built in six sizes, with the power built in and under the table. The frame construction of the portable saw rig is structural steel. The lower members or skids are 3-inch angles re- inforced with 3%x3%-inch _ timbers. The legs and upper members are 2%- inch angles. The table is a %-inch steel plate, 42 inches wide and 56 inches long, bound around the edges with a 1'4-inch angle. The table is hinged to the rear of the frame. It is raised and lowered at the front by a raising screw, and is locked at the front corners by brackets and hand nuts. A _ removable throat piece permits the saws to be changed without raising the table. The saw and jointer gages are iron and steel. The rip and jointer gages are adjustable from square to 45 degrees and can be readily locked in any position. The arbor is steel. The long bearings are lined with bearing metal and are wick oiling, with large oil wells cast under them. The arbor is fitted with a collar to take up the end play. The diameter of the arbor where the saw fits, is 1 inch. Band Saw Attachment The frame of the band saw is a l- piece casting channel section. It is mounted on the extension of the skid and is braced to the end of the saw frame. The wheels are iron, faced with rubber bands. The upper wheel can be tilted for aligning the blade as well as adjusted vertically to give the proper tension to the blade. Any size of blade up to 34 inch in width can be handled. PORTABLE SAW RIG 226 The table is iron and is 18x 18% inches, It can be tilted to any angle up to 45 degrees and locked in position. The guide bar is steel, and is fitted with a roller guide. The drive is by belt from the countershaft to a tight and loose pulley on the band saw. The saw is started and stopped independently by means of its own belt shifter. The hori- zontal capacity is 20 inches and the ver- tical capacity 8 inches. The height of the table from the floor is 41 inches. The frame of the saw rig boring and mortising attachment is a 1-piece casting, bolted and braced to the saw frame. The arbor which carries the bits is belt driven from the countershaft. The table is 22 inches long and 8 inches wide and has a vertical adjustment of 7 inches through a removable crank. It slides up and down on steel rods and can be clamped at any height. It has a_hori- zontal travel of 8 inches by means of a foot pedal, being automatically returned. by a- spring. The gage can be set at. cany.- angele. An adjust- able stop regulates the depth of the boring or mortising. This attach- ment is designed to cut mortises up to 34-inch in any length and to bore holes up to 1%-inch diameter. The jointer of this portable saw rig has its main frame shaped to fasten rigidly on to the side of the saw frame. The frame is a l-piece casting. with planed inclines on which the tables are mounted. Both tables are adjustable and are 40 inches long. The front table has a rabbetting arm extending over the bearing. The fence is carried on the front table and is adjustable across the table to the full width of the knives. It is adjustable to any angle up to 45 degrees and can be securely locked in position. The headis cylindrical and car- ries four 634-inch knives. The head is covered by a safety guard which un- covers the knives to the width of the stock and automatically returns as the stock leaves. The jointer is stopped and started by means of a friction clutch on the countershaft. The C: H. & E. Mfg. Co. advises that this outfit is being used by a number of ship yards, including the Chester Ship Building Co., Chester, Pa., the New York Ship Building Corporation, Cam- den, N. J., and the Pennsylvania Ship Building Co., Gloucester, N. J A. B.
