The Rich Sash Trimmer.
A machine embodying many interesting features of construction and designed by experienced sash manufacturers for coping the ends of the bars and muntings used in making diamond and all irregular sash is shown in Fig. 2 of the engravings. The machine carries cutters which it is claimed will trim the ends of- these pieces to the exact shape to make perfect joints, no matter what the angle of intersection may be, while at the same time each piece can be cut to the length required to properly fit the particular place in which it is to go. An inspection of the illustration will show that the machine consists of a base and column on which is mounted a vertically sliding head carrying two specially shaped cutters and a face plate provided with swinging tables, on which the work is placed. A foot treadle is provided for operating the sliding head. The cutters are right and left, and being made the exact shape of the molded outline of the sash cut recesses in the ends of the bars or muntings which make perfect points at the angle required. The manufacturers state that they are sharpened in the same way as a common chisel, without danger of losing the proper shape, and will last for a long time. In operating the machine the bar or munting is laid on a wooden bed piece which is grooved to fit its outline and which supports its lower edge at the moment of cutting, so as to prevent any breaking down or splintering of the edges. These bed pieces are carried on swinging tables, which are so made as to be instantly adjustable to any angle up to 75 degrees. Each table is provided with three adjustable spring stops, so that after once setting it can be changed from one angle to another and returned without any delay in resetting. It is stated that the value of this machine over hand work is indicated by the fact that one man can cut in and make 150 to 200 diamond lights per day, while all whittling with knife and chisel is dispensed with. Reference is also made to the labor saving qualities of the machine, even in cases where only a few sash are to be made, for the reason that it is unnecessary to lay out a plan of the whole in order to get the lengths of the bars and muntings, as each can be cut at once to the exact length required. On curved work the machine is, as the manufacturers put it, "almost a necessity, as there is no difficulty in holding the pieces and cutting to the correct bevel, which saves much expensive whittling." Still another important feature of the machine is its value for coping moldings, as they can be made to fit as easily as they can be mitered, with the added advantage that the joint is not so likely to be drawn open when nailing in place. The machine stands 5 feet in height, occupies a floor space 2 x 2 1/2 feet and is manufactured by L. S. Heald & Son
