Germana/*hn Be it known ythat I, Emana HAnnoLo, a
4citizen of the .United States, residing at Leetonia, in the 4county of IColumbiana. and State of Ohio, have invented certain new and useful Improvements in Cutter-Heads, of which the following is a specification.
The presentinvention relates more `parheads for jointers, planers and similar Wood Working machines, and the principal object is to provide novel, simple and highlyetiective means for securing the cutter blades inplace in the head or body, said means Ynot only securely holding the blades, but being also itself held against accidental displacement.
Two embodimentsofthe construction are illustrated in the accompanying drawings, wherein Figure l is a View in elevation of a head or rotary cutter, showing the preferred embodiment of the invention. Fig. 2 is an end elevation partially in section on the line 2-2 of Fig. l. Fig. 3 shows detail views of one of the` wedges. Fig. Il is a View in elevation of a portion of a modified form of construction. Fig. 5 is a detail perspective view of the wedge member, forming a part of this modification. Fig. G is a detail view of the holding bar 10, showing a modification of the means for adjusting the-cutter blade 9. Fig. 7 in a detail view showing the application of this modification.
Similar reference'nunierals designate corresponding parts in all the. figures of the drawings.
in the embodiment disclosed in Figs. 'l-3 inclusive, the body (i of the heador cutter is substantially of the usual shape, and has a pluralitv of cutter-blade receiving seats 7, with outwardly tapered sockets 8 communicating uith'tlie seats, aplurality of these .sockets bein;I associated with each seat iliroughoul the length of the head. Arranged in cach seat a cutter blade 9 and a throat-piece 10. constituting a holding bar for thc cutter, and may also have a flange portion ll arranged Ibeneath the blade, which flange portion may, in lui'n, be provided willi blade-adjusting screws 12 bearing against the iiinei' edge of the blade.
A very compact and rigid construction is provided by having'the holding bar or throat piece 10 of substantialy an --:ihape in cross-section with the knife blade solidly seated within 'and against said bar. Also substantially Specification of Letters Patent. Application l'eol Angiust 1l.,4 1909. Serial No. 512,398.
Patented Dec. 1d, 1909.
the various elements constituting the fastenlng) are rendered more effective and less ha le to displacement by having the knifereceiving seat disposed substantially Vtangentially to the axis of the body, and the outwardly tapered socket lying in a plane radial to the axis of the body.
Arranced in each ofthe sockets 8, is an outwardly tapered wedge-block 13 having a threaded bore therethrough, as shown at 14, to receive a thrust screw l5 screwed through said bore and bearing against the bottom of the socket. This screw has au angular recess 16 to receive an actuating tool. In the construction of this device, the sockets 8 are first drilled into lthe body and the seat 7 then milled therein, said seat being disposed tangentally and cutting through the sockets, as shown. It will be obvious that the -blade can-be readily placed in position, and when in place, can be securely fastened by turning the thrust screws l5, which will move the wedge' 'blocks outwardly, thus causing the holding bar to clamp rmly against the blade.
A slight modification of the structure is illustrated in Figs. 4 and 5. ln this form of construction, the body is designated 17, and is provided with a seat to receive the cutting blade 18, andthe throat-piece or hold? ing bar 19. Instead wedges, a single outwardly tapered Wedge bar 2O is employed, as shown in Fig. 5, and is provided with a plurality of threaded openings 21 that 'receive thrust'screws 22. The socket in this instance extends the entire length of the body, and it will be obvious that by rotating the thrust screws 22, the Wed e bar or block 20 will be forced outward?, effecting the saine clamping action as above described. Also a slight' modication of the means for adjusting the cutter-blade 9 may be had by providing the holding bar l0 with two or more series of pin holes Q3, diagonally disposed on the face of the bar, to receive the pins 24, against which the back edge of the cutter blade'inay rest, as shown in Figs. 6 and 7. It is' obvious that with this arrangement the blade may 'be readily adjusted by advancing the pins 24 forward in the pin holes 23 as the cutter blade is worn away.
From the foregoing, it is thought that the construction, operation and manvadvantages of the herein described inventionwill of a plurality of be apparent to those skilled in the art with-- l to wedge it between the holding bar and one out further description, and ,it will be understood that various changes in the size, l shape, proportion and minor details of eonstruction may be resorted to without del parting from the spirit, or sacrificing any l of the advantages of the invention. I
Having thus fully described my invention, l what I claim as new and desire to secure by l Letters-Patent, is
1. In a structure'of the character set forth, the body having a knife-receiving seat disposed substantially tangential to the axis of the body, a knife blade located in said seat, a holding bar arranged Ain the seat alongside of the knife bladc,'said body also hav-ing an outwardly tapered socket lying in a planesubstantially radial to the axis of the body, an outwardly tapered wedge-block located in the socket and bearing against the` bar, and means carried by the block fon forcing the latter in an outward direction wall of the socket.
2. In a structure of the class described, the combination of a body havinga longitudinal knife-receiving seat disposed substantially tangential to the axis of the body, and a plurality of sockets opening into said seat and lying in a plane substantially radial toV the axis of the body, a holding bar arranged 1n the kmfe seat, a knife blade seated within l and against the holding bar, a plurality of clamping Wedges located in the sockets and cach having a flat side bearing against the holding bar, and thrust screws threaded through the Wedges and stepped against the I bottoms of the sockets.
3. In a structure ofthe character de- I. scribed, the combination with a body having a knife-receiving'v seat and the knife blade therein, of a throat piece arranged in the seat at one side of the blade and having a flange portion underlying the inner edge of the knife blade, and blade adjusting means carried by said flange portion, and fastening means for the throat piece.
4. In a structure of the character set forth, the combination with a body having a knifereceiving seat and a plurality of sockets opening into the seat, ofa knife arranged in the seat', a holding bar also arranged in the seat and provided with laterally-extending adjustably-mounted knife adjusting pins, a plurality of clamping' wedges located in the sockets and having flat sides bearing against the holding bar, and thrus`t-screws threaded through the Wedges and bearing against the vbottoms of the sockets.
In rtestimony whereof I hereunto aiiix my signature in the presence of two witnesses.
