I wuewto a earns" rAT NT ()FFICE.
' ELMER Harmonia, OQFVYLEETONIA', OHIO, ASSIGNOR'TO THE cnnsonnr MACHINE COMPANY, or LEEroNm, OHIO.
To all whom it may concern: 7 ,Be it known that .I, ELMER HARROLD, a
' citizen ofthe :United States, residing at Lee'tonia, in the county. of Columbiana and State of Ohi o, have" invented certain new and useful Improvements in RotaryCutter- 7 Heads, of whichthe following is a specification. r
.Thisinvention relates towthe subject of woodworking machinery,'and more particu larly to rotary cutter he'adsfor jointers,
planers, and similar woodworking machines.
To this end the invention primarily-has in view the provision of simple and prac-' tical means for securing the cutter blades in place in the head or body, said meansjnot only securely holding theblades, but being also itself held against accidental displace ment. 1 v.
. In carrying out this general object, the invention particularly contemplates an advan- I tageous improvement in the construction of the fastening means disclosed. 1n, and covered by, my former Patent No; 943,540, dated December 14;, 1909. In this connection, the present inventionis intended to provide a 5 construction. whichsecures' all of theimportant and practical advantages of the construction set forth' in the former patent aforesaidwhile at the same time affording means whereby the holdingv bar -or throat piece may be' readily and bodily removed from its socket, after the knife bladehas been removed, without drawing said throat piece or holding bar lengthwise out of its socket from one endof the cutter head. or
1 body, as is necessary in' thefconstruction disclosed in said former patent.
With these and other objects in view, which will more "readily appear to those familiar with the art as the nature of the-invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fullydescribed, illustrated, andi claimed.
In the accompanying drawings: Figure 1,
ROTARY CUTTER-HEAD.
3 I Specification of Letters Patent. Patented Sept, 21, 1915, Application filed A ril 11, 1910. Serial No. 554,765.
5 is a detail end view of a form of tool or wrench employed for adjusting the knife blades.
Similar references designate correspond ng parts in the several figures of the drawings.
i In theembodiment of the invention disclosed in the drawings, the body 6 of the head or cutter is substantially of the usual shape, and has a plurality of knife receiving seats 7, and outwardly tapering sockets 8 communicating with the seats, a plurality of these sockets being associated with each seat throughout the length of the head. Arranged in each seat is a knifeblade 9 and a throat piece 10, the latter constituting a holding bar for the knife blade. According to-the present embodiment of the invention, the knife blade is of the ordinary form and provided with'the outer beveled cutting edge 9* and is adapted to be heldflat against one side wall of its seat 7 by the throat piece or holding bar 10, which latter flatly and solidly bears against one side face of the knife blade throughout the entire area of the latter. Also, according to the embodiment of the invention disclosed herein, the side of the throat piece or holding bar 10 which flatly abuts one side of the knife blade, is plain and unflanged throughout, While at what'may be termed the bottom corner of the throat piece farthest from the knife blade, the said'throat piece is provided with a longitudinal locking flange 11 which interlocks with a keeper seat or groove 12 formed at one bottom corner of the seat 7 which receives the throat piece and the knife blade. When the parts are assembled, this construction serves'to lock the throat piece or holding bar against outward displacement, while at the same time permitting'the throat piece or holding bar to be readily removed without sliding it endwise from its seat, that is to say, when the fastening is loosened up and the knife blade re- 'moved from its seat or socket, the throat piece or holding bar may be pushed laterally sufficiently to disengage the flange 11 from the keeper seat 12, whereupon, the said throat piece or holding bar may be readily lifted bodily from the said seat or socket, thus greatly facilitating the assembling and disassembling of the parts.
In the construction described, it will also be observed that the various elements con-
