The side frames forming the bed are bolted to the main frame and form the ways on which the work table travels. The table frame j, [Fig. 3187], is provided with rollers, which rest on the upper surface of the bed and reduce the friction.
Fig. 3190.
The table is made in convenient sections bolted to the table frame j, and at their points of junction the work-holding dogs are placed, the construction being shown in [Fig. 3190], in which t′ is the end of one, and t′′ the end of another section of the table. Referring now to [Figs. 3187] and [3190], upon the edge of the table are the abutment pieces a′, a′′, against which the work is pulled by the dog, which is operated by the screw, which is squared at its outer end to receive the handle m, [Fig. 3187].
The rate of work feed is 30 feet per minute and the quick return motion is 60 feet per minute.
MOULDING MACHINES.
In moulding machines for light work the feed rolls and cutter head overhang the frame, such machines being designated as outside moulding machines.
[Fig. 3191] represents a machine of this class constructed by J. A. Fay & Company.
