KNOW ALL MEN BY THESE PRESENTS:

That I, H. A. LEE, of `the city and county of Worcester, and Commonwealth ot` `Massachusetts, have invented certain new and useful improvements in Combined Open and Closed Matcher-Heads; and'I do hereby declare that the following is a full, clear, and exact description of Vthe same, reference being had to the accompanying drawings, forming a part of this specication, in which- Figure 1 represents a. perspective'view of my combined open and closed matcher-head.

Figure 2 represents a side view, and y Figure 3 represents a cross-section on line A B, fig. 2.

To enable those skilled in the art to which my invention belongs' to make and use the same, I will proceed to describe it.

In the drawings, A is the hole through which the vertical match-spindle passes, and to which the head B is fastened in the ordinary manner. In cutting the various kinds of mouldings, it is the practice to make up the cutter by separate pieces, a I1 c, or any other desired number and shape. These sections or cutters are placed in the straight grooves or slots C C, and are held in place by the sctscrews d d, which may bear directly upon the edge of the upper section, `or upon a hlankpiece, e, when the sections do not till the slots C.

A matcherhead made as above described is called a closed head, since the sections of the cutter are held in close confinement in the slot C. It often happens that it is necessary to use a cutter D, having an inclined edge,f, as shown in g. 2, and as the edge f of such a. cutter, if used in the slots C C, would have to be made inclined and of thc exact inclination of the form to be cut, thusnecessitating the making of a new cutter, or grinding away of the edge of an old one, every time a change was desired in the form ot' cut, it has been the prac-tice to have a separate head with grooves E, for the purpose of fastening on square cutters D, having slots g g, through which bolts F passed to screw into nuts 1, slipped into the grooves E. By this mode of construc-` tion the cutter D can be inclined, asshown in figs. 1 and 2, so as to bring the edge f upon any desired angle. In lieu of slots E, the bolts F may screw directly into holes bored in the head part B.

A head constructed as last above described is called an open inatcherhoad, and `it will be seen from the foregoing explanations that neither could be made to answer for the other very conveniently, since the cutter,- made up'ot sections, could not be safely used when fastened upon the outside. To combine the two hcads'in one, and that, too, without materially increasing the expense and weight of the matcher-head, was the object sought to be attained by my present invention. In addition to the slots C C and grooves E E for fastening the di'erent cutters, the head part Bis cut away at the points m m, so as to form clearing throats n n for the cutters D. In making the closed head it is necessary to have the rounded parts J .I in order to Vgive suiiicient strength, and hence it becomesnecessarv, in order to use the head with the cutters D, to have the metal cut away to 'form the throats n n.

I do not cla-im an open matcher-head, nor a closed matcher-head, separately considered, nor do I claim a head for supporting cutters like that described in the patent granted to S. F. Foreman, June 29, 1858; but what I do ciuim as my invention, and desire to secure by Letters Patent, is-

A matcher-h-ead constructed in the peculiar manner above described, and as shown in the drawings, so thatv it may be used equally well in lieu of either a closed or an open matcher-head, as and for the purposes set forth.

HENRY A. LEE.
