Specification of Letters Patent.

Patented` Oct. 12, 1909.

Application led May- 7, 1909. SerialA N o. 494,541. v

Beit known'that I, CHARLES H. HANSHUE, a citizen of the United States, residing at Beloit, in the county of Rock and State of VVisconsimha've invented certain new and useful lImprovements in Stovepipe-Cutters, of which the vfollowing is a specification.

My invention relates to stove pipe cutters, and myl object is to providev a simple and inexpensive device by which stove pipes may be cut to desired lengths," without mashing or otherwise destroying the shape thereof.

My invention is illustrated in the accompan'ying drawings, forming a part of this specification, and in which,

Figure 1 is a side elevation of -my improved. device partly broken away and in section. Fig. 2 is a sectional View through a portion of the cuttin blade, andillustrating the cutter frame 1n plan, and, Fig. 3

\ is. a perspective view ofthe pivot pin.

In the embodiment of my invention as shown, I provide a curved, or more particu'- larly, semi-circular cutter guide frame comv. outer surface with spaced parallel upstandprising a curved strip 5, of relatively fiat materia-l, provided centrally upon its convex ing ears/6, one arranged upon each side of a longitudinal slot 7 centrally of saidframe,

and which ears are provided with alined aperturesfor the reception of a pivot pin S, having an enlargedmilled head 9 by which it may be readily inserted within, or withdrawn from said openings. A cutting blade l0 is provided with a handle' 10a, and is.

adapted for insertion between ears 6, to operate upon the stove pipe through the frame slot 7, when said frameis placed upon said pipe a portion of which is illustrated in dotted lipes in Fig. l.

In theinitial operation of the device, pivot pin 8 is withdrawn, and blade` 10 is freed to be reciprocated between ears 6, with its toothed edge .11 against the stove pipe through slots 7 by which means a slot'is sawed in the stove pipe to permit ofthe insertion of the forward pointed end 12 of sai-d blade downwardlyinto the pipe to the position shown in dotted' lines in Fig. 1.

Inasmuchl as the blade is pointed as at 12, it may be of course forced into the pipe without the loss of time incident to saving the slot, but as the forcing of thepoint into the pipetends to destroy to a certain extent the shape and the contour of the pipe, it is obvious that the method of sawing isfar superior'. The pivot pin Sisthen inserted through the apertures of ears 6, and through an aperture I3 inthe cutting blade I0, tlius` mounting said blade for pivotal movement whereby its squared edge 14, opposite its toothededge 11, may be swung upwardly against the internal surface of the pipe wall, shearing a strip therefrom, between said cutter edge 14 and the longitudinal edges of slot 7 which may be continued entirely around the pipe to sever the same.

From the foregoing, it will be readily apparent that as the cutting "operation, takes place against the cutter-frame, the shape of lthe pipe is maintained throughout and that the resulting edges willbe even and clean l cut.

clalm: In a stove plpe cutter of the character described, the combination with a curved supporting frame provided with a longitudinally arranged slot,'and alined ears ar CHARLES H, HANSHUE.
