SINGLE-HEAD AUTOMATIC GAINING MACHINE.
The accompanying engraving represents a complete and convenient single-head automatic gaining machine, especially designed for carpenters, car and ship builders, wagon, truck, carriage, agricultural implement manufacturers and general woodworkers, for cutting g ins. grooves, tenons and miters—either square, angular or double angular—in either hard or soft wood, from the most delicate sizes up to 8 inches wide, 3 inches deep, and from 1 inch to 24 inches long, and performing the work true and smooth without slivering. Cutter heads can be used for any class of work in this line, or by the use of a cut-off saw, it can be utilized for cutting off timber.
It is adapted for cutting gains or grooves of an equal depth over the surface of warped boards, as shown by the sample of work at the base of the machine.
The main frame is a heavy casting, in one piece, with cored center and broad base. The top position of the frame is planed true and accurately fitted for the support of the carriage, which is gibbed to it, and adjustable over its entire length by a hand wheel and screw to adjust the head to any portion of the work without moving the latter on the table.
The cutter head spindle, of steel, is 1 15/16 inches diameter by 24 inches long, and the cutter head may be used on either end, or one at each end of the spindle to cut two gains at one time, or can be placed between the bearings with the driving pulley outside, as may best suit the nature of the work.
The sliding ram by which the cutter head is carried is fitted with a device whereby the travel of the head may be quickly adjusted from 1-inch to 24 inch stroke, and it is provided with a quick return movement. The ram can be set to any desired angle for the purpose of cutting angular gains.
The table bracket is fitted to the frame in gibbed ways and is adjustable up or down by a heavy hand wheel and screw to regulate the depth of cut. The table proper is provided with a screw clamp, for holding large work, and a small chuck, as shown at the base of the machine, for short work. The table may be tilted from side to side or from end to end in either direction, forming a universal adjustment for any required straight or angular gains, and it is supplied with an index so that it can be accurately adjusted to any degree without the use of a rule.
The attachment shown at the base of the machine is used to center a wagon axle by its skeins when cutting hound and reach gains.
The weight of the machine complete is 2,500 pounds; total floor space occupied is 5 feet by 4 feet 6 inches.
A counter is furnished as follows: Shaft, 5 feet 6 inches long by 1 15/16 inches diameter; two No. 2 ball and socket adjustable drop hangers; driving pulley, 16 inches by 16 inches with split hub; pulley to release feed, 3½ inches by 3 inches; one flange on shaft to guide feed belt; tight and loose pulleys, 10 inches by 6 inches; speed, 750 rotations per minute.
This machine is built by the Defiance Machine Works, Defiance, Ohio.
