EIDE H. HINNERS, OF NEW YORK, N. Y.

IMPROVEMENT IN CUTTER-HEADS FOR MOLDlNGS.

Specification forming part of Letters Patent No. 140,626, dated July 8, 1873; application filed December 14, 1872.

T 0 a l whom it may concern:

it known that I, E. H. HINNERS, of the '77, county and State of New York, have inwted a new Improy'ement in Gutter-Heads I 1r Molding, of which the following is a speci fixation:

The object of my invention is to produce a rotary cutter-head for making moldings with a rabbet at one side, separated from the molding by a narrow strip too thin and weak to sustain the strain to which it would be subject if the rabbet was formed with the ordinary rotary planing-cutter; and it consists of a staggered saw attached to the cutter-head of the melding-planer to form the rabbet.

Figure 1 is a side elevation of the cutterllead, such as I propose to employ, and Fig. 2 is an end elevation.

Similar letters of reference indicate correspondin g parts.

The molding, such as I wish to produce, is shown dotted in section in Fig. 1, wherein D represents the rabbet and E the thin strip of wood I wish to leave between it and the molding. This thin strip would not have strength to resist the tendency of the cutters to split off from the main portion of the wood if the ordinary planing-cutters were used both for the molding and the rabbet, but as the planin g-cutters must be used for the mo ding I therefore make a cutter-head for producing this work of a stock, A, with molding-cutters B, anda staggered saw, 0, all as represented in the drawing, and thus considerably lesscn the splitting-strain on the strip E, as the saw has much less of such effect than the planing-cutters have.

I am aware that similar cutter-heads have been long known to the public, and some pos sessin g many of the general characteristics which are to be found in mine, but none exhibiting the special feature now disclosed to thepublic by me.

Having thus described my invention, I claim as new and desire to secure by Letters Patent Acutter-head consisting of the molding-cutters B and staggered saw 0, arranged on the cutter-head A to form a rabbet, I), separated from the molding by a narrow strip, E, substantially as represented in the drawing.

E. H. HINNERS.
