TOOL FOR CUTTING OFF GAS-PIPE OUTLETS.

SPECIFICATION forming part of Letters Patent No. 595,727, dated December 21, 1897. Application filed Augu t 191 1897. Serial No. 648,808. (No model.)

To all whom it may concern.

Be it known that 1, JOHN L. OEFINGER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tools for Cutting Off Gas- Pipe Outlets; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a pipe-cutter adapted for general use and especially adapted for cutting off gas-pipe outlets close to the walls. It is of course well understood that in building houses the gaspipe outlets are ordinarly left to project anywhere from two to six inches, and, on the other hand, that it is desirable that these outlets should be as short as possible, especially when combination or electric fixtures are to be applied, as if the outlets are long it becomes necessary to use very deep canopies to cover the insulating-joints. So far as I am aware none of the Various pipe-cutters now in use will cut close enough to the wall to leave only such length of pipe as will be just suflicient to attach thereto a cap or fixture. Heretofore when it has been desired to out 01f gaspipe outlets close to the wall it has been necessary to resort to the use of a hack-saw, which is quite inconvenient and is, moreover, likely to disfigure the Wall quite seriously. With my novel tool an outlet can be cut off within three-eighths of an inch of the wall and left in perfect condition to be threaded in the usual manner for the purpose of hanging the fixtures.

In order that others may be enabled to understand the construction and operation of my novel tool, I will proceed to describe the same, referring by numbers and letters to the accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation illustrating my novel tool in use; Fig. 2, a front elevation corresponding thereto; Fig. 3, a central horizontal section, and Fig. 4 is a rear elevation.

A denotes the body of my novel tool, which is shown as provided with internally-threaded hubs l to receive operating-handles 2, with pairs of lugs 3 and with a central sleeve 4,

which receives the end of the gas-pipe outlet to be cut off. In practice the body, the pairs of lugs, and the central sleeve are cast in a single piece, and the rear portion of the sleeve In use the operator turns the cone outwardon the sleeve, which permits the inner ends of the levers to swing inward, and consequently throws the outer ends carrying the cutters outward. The tool is then placed over the gas-pipe outlet to be cut, the outlet passing between the cutters into the sleeve, as clearly shown in Fig. 3. The operator then turns the cone inward on the sleeve,

throwing the inner ends of the levers outward and the outer ends, which carry the cutters, inward and causing the cutters to engage the pipe to be cut 0E. The operator then by means of the operating-handles turns the tool upon the pipe, setting the cutters inward, if required, by means of the cone until the end is cut off.

Having thus described my invention,- I claim- 7 l.
