," @ZZ whom, it muy concern,.-
Be itknown that I, FRANZ .I.\VOOD,a citizen of the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented new and useful Improvements in Knives for Band-Cutters and Feeders, of which the following is a specification.
This invention relates to improvements in knives for band-cutters, the object being to ro provide a rotary cutter of such construction that the knife or blade may be removed from that part which is carried by the shaft, so that the blade can be removed for the purpose of sharpening its cutting edge or substituting a blade having a cutting edge of a different character; and the invention consists in the combination with side plates mounted on a shaft and connected to each other to provide a socket for a part of the knife or zo blade and means for engaging the knife to hold it in place when inserted in the socket, so that the knife may be readily removed, the retaining means being integral with one of the side plates, as Will be hereinafter set forth, and specifically pointed out in the claim.
In the accompanying drawings, Figures l and 2 are side elevations of a knife or bandcutter made in accord with the invention. 3o Fig. 3 is a sectional view on the line 5t of Fig. l, Fig. 4 is a side view of a portion of the knife or cutting blade, and Figs. 5 and 6 are side elevations of parts of the side plates.
In carrying out theinvention there are secured to a shaft in any suitable manner and at proper distances apart side plates l and 2, which are attached to each other to provide a socket for the reception of the knife or blade 3. Between the plates land 2 there is 4o riveted a plate 4, shaped to correspond with the part of the blade 3 which is seated in the socket, the outline being indicated by dotted lines, and said plate 4 is of the sam-e thickness as the portion of the blade which enters the kerf or socket between the side plates.
The side plate l has-punched or otherwise formed therethrough' a hole or opening 5, which may be either circular, as shown in Fig. l, or semicircular, as) shown in Fig. G, 5o and such opening is so positioned that it will register partially with the catch or lip on the opposite plate and with the opening through the blade. lVhen the parts are assembled, there will be a portion of the side plate l above the lip and the opening` through the blade, against which the lip may abut.
The side plate 2 is cut away, so as to leave integral with the side plate a lip or catch 6, which is bent or stvaged so that the end will extend toward the opposite side plate, against 6o which it may abut when not forced therefrom, and the part of the lip farthest from the edge of the side plate corresponds with theinternal configuration of the opening` 7 through the blade.
The knife-blade 3 in practice is preferably provided with a circular opening 7, and its part which lies within the socket is shaped to correspond with the upper edge of the plate, said blade also having a cutting edge 7o which is eccentric to the shaft. The cutting edge may be either smooth or notched. In placing the knife in the socket the heel is passed into the recess near one end of the plate 4. The knife is then swung until seated, when the lip G Will spring into the opening '7 and hold the knife securely in place. To remove the knife, it is only necessary to push the lip against the movement which is imparted thereto bythe bend therein, andv 8o when the end of the lip is forced beyond the side of the blade, Which can be done by inserting a tool, punch, or even a nger into the opening 5 and against the inner side of the lip to move vsaid lip beyond the side of the blade, then the blade can be drawn ont of its socket and another one inserted.
This invention provides a removable blade for band-cutters, and by having on hand extra blades there need be no delay or stoppage 9o of the machine to sharpen the knives. The construction is such that there are no parts which can become detached, and by having double plates a rigid support for the blade is provided.
I claim- Y A knife, consisting oftwoside plates attached one to the other to provide a socket, one of the plates having an aperture through the same, an inward-projecting lip integral roo with one of the plates and positioned approximately opposite the aperture in the other side plate, and a removable blade shaped to my hand in the presence of two subscribing enter the socket the blade having an aper- Witnesses. ture therethrough into which the lip passes to engage the Wall of the aperture and retain 5 the blade in engagement with the side plate, Witnesses:
substantially as shown. HOWARD J CLARK,
In testimony whereof I have hereunto set i MAUDE DIXSON.
