Description

GAUGE FOR NIPPLE CUTTERS Filed Aug 21 1935 Invenor '\m l v t]. 7 Z7a7ZZ A Hamel Patented Oct. 13, 1936 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to a gauge for pipe or nipple cutter, the general object of the invention being to provide a graduated bar adapted to be connected to the shank part of a cutter between the cutting jaws thereof with an adjustable stop bar on the gauge bar which determines the length of pipe or nipple to be cut.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure 1 is an elevation showing the invention applied to a cutting tool.

Figure 2 is a front elevation of the device.

Figure 3 is a detail view of the sections of the graduated bar.

In these views the letter A indicates a cutting tool which may be of hand or power type and which has the usual cutters a extending into the space between the two jaws thereof.

In carrying out my invention I provide a graduated bar which is made up of sections I and I. Section I is provided at one end with a pin 6, which is adapted to loosely fit into the opening I of section I to join said sections. One end of section I is threaded into a hole formed in a side of the shank of the tool slightly in front of the stationary jaw of the cutter, the section being held in place by a nut 2. Grooves 8 and 9 are formed adjacent one of the ends of each section I and l respectively to receive the terminals of the coil spring I0. Accordingly, with section I attached to the stationary jaw of the cutter, section I is adapted to be moved outwardly, and to be retracted to its normal position, as shown in Figure 2, by the spring III.

A stop forming bar 3 has an enlargement 4 thereon which has a hole passing therethrough through which the section I of the graduated bar passes. A set screw 5 passes through the adjacent end of the bar 3, which has a threaded socket therein intersecting the opening on the bar, the inner end of the screw being pointed to engage any desired one of the row of countersunk depressions I I formed in the section I of the graduated bar.

Thus when the device is in place the stop placed against the bar 3 and then the pipe is cut.

To compensate for the thickness of the cutter in accurately cutting the work, a spring-pressed section I is provided on the graduated bar, which is adapted to move outwardly as the thickness of the cutters increase.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is:-

1. A gauge for cutting implements comprising a threaded member adapted to be screw-threaded into the emplement, an elongated section provided with a reduced extension, said threaded member having a bore therein for slidably receiving the reduced extension, 2. spring connection between the threaded member and the elongated section, a slidable gauge member on the elongated section, and means for fixing the slidable member in definite positions on the elongated section.

2. A gauge for cutting implements comprising a threaded member adapted to be screw-driven into the implement, an elongated section provided with a reduced extension, said threaded member having a bore therein for slidably receiving the reduced extension, a spring connection between the threaded member and the elongated section, a slidable gauge member on the elongated section, and means for fixing the slidable member in definite positions on the elongated section, said spring being of coiled construction, both said threaded member and elongated section being provided with a circumferential groove for receiving the corresponding end convolution of the spring, said spring being adapted to retain the threaded member and elongated section in end to end abutting relation.
