METAL CUTTING DEVICE.
No. 495,356. Patented Apr. 11, 1893.

HARTVIG O. MULLER, OF HAMILTON, NEW YORK.
METAL-CUTTING DEVICE.
SPECIFICATION forming part of Letters Patent No. 495,356, dated April 11, 1893.- Application filed October 25, 1892. Serial No. 449,937. (No model.)
This invention relates to certain new anduseful improvements in devices for cutting pipe, gutters, conductors and other kinds of light iron or tin pipes and the like, and it has for its objects among others to provide a simple, cheap, yet efficient device for this purpose designed to be operated by the foot so that both hands of the operator may be free to handle the pipe or other article to be cut.
Other obi cats and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claims.
The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which Figure 1 is a perspective view of my improved device. Fig. 2 is a vertical section with parts in side elevation, of the upper end of the device. Fig. 3 is a view at right an gles to Fig. 2 with parts in sect-ion and parts in elevation.
Like letters of referenceindicate like parts throughout the several views.
Referring now to the details of the drawings by letter, A designates a portion of a bench or other support upon which the pipe to be cut is designed to be supported and which bench is provided with a vertical opening a through which the cutter is designed to reciprocate. Around this opening is a metal frame B from which depends a central guide portion b extending below the opening as seen in all of the views and which is integral with or rigidly affixed to the vertical tubular portion 0 which is provided upon its rear face with a vertical slot 0 for a purpose which will soon be explained. The upper end of this tubular portion is provided with a cap or end 0' in which is held one end of a spring D as seen best in Fig. 2, the other end being connected with the upper end of the knife or cutter E which has a cylindrical portion e fitted to slide easily within the tubular portion as seen best in Fig. 2, the other end of the cylindrical portion extending through the tubular portion as shown and provided with an eye or other analogous means 6 to which is connected one end of the rod or linkF the other end of which is connected with a stirrup G which is provided with projecting pins g at the ends which are adapted to slide in vertical slots or guides h in the standards H rising from the plate H which is secured to the floor in any suitable manner as seen in Fig. l.
The knife or cutter F- has its under face curved upward slightly from its junction with the cylindrical portion toward its end which is brought to a point so that it can be employed to puncture the pipe to start the cut.
The operation will be readily understood.
The cutter is normally in its elevated position, that shown in Fig. 2, and when it is desired to cut a pipe or other article the latter is placed upon the bench, the end of the knife is forced through the pipe by pushing the latter against the point of the cutter orknife and then the foot is placed upon the stirrup and the latter pressed downward which brings down the knife and cuts the pipe which latter should at the same time be given a partial rotary movement by the hands which are both free to manipulate the pipe, the movement to the knife being given by the foot. When pressu re is removed fromthestirrup the spring returns the parts to their normal position, when the pipe can be given a partial turn and the operation repeated. The rod or link F is pivotally connected with the cutter and stirrup so as to insure a vertical movement of the cutter even should the stirrup turn on its pintles as it moves.
Modifications in detail may be resorted to without departing from the spirit of the in-. vention or sacrificing any of its advantages.
What I claim as new is p 1. The combination with the support with a slot and a metal frame therearound, of the tubular vertical portion with slot, the cutter having portion working in said tubular portion, a stirrup, a pivotal connection between the stirrup and cutter, and a spring in the tubular portion connected with the cutter, as set forth.
2. The combination with the plate with slotted standards, of the stirrup with pins working in the slots of the standards, the rod pivotally connected with the stirrup, the cutter having portion connected with said rod, the slotted support with its frame and tubular portion, and the spring within said tubu- 1o lar portion and connected with the cutter, substantially as specified.
In testimony whereof I affix my signature in presence of two witnesses.
