Be it known that I, DAVE W. COLLINS, a citizen of the United States, residing at WVilson, in the county of Mississippi and State of Arkansas, have invented new and useful Oar- Repairers Tools, of which the following is a specification.

This invention relates to car repairers tools and its object is to combine a thread cutter and lifting jack in a compact and simple structure which can be conveniently manipulated and which is adapted for use wherever a small jack is necessary and for cutting threads in places which are not readily accessible.

Although the device is particularly useful to car repairers it can of course be employed in a large number of places.

T he invention consists of a die holder which is detachably seated within a base connected to a cap having means whereby a handle may be detachably secured to it for the purpose of rotating the entire base. A head is rotatably mounted on the cap and is adapted to contact with an abutment during the rotation of the dies. Said dies when not in use for cut ting threads can be employed for engaging the threads on a bolt and when a bolt is disposed in this manner the entire tool can be utilized as a lifting jack.

The invention also consists of certain other novel features of construction and combination of parts, which will be hereinafter more fully described and claimed.

In the accompanying drawings is shown the preferred form of the invention.

In said drawings: Figure 1 is a perspective view of the tool; Fig. 2 is a section therethrough showing a bolt in position therein whereby the device may be used as a jack; and Fig. 3 is a bottom view of the tool.

Referring to the figures by numerals of reference 1 is a ring like base having upstanding supports 2 thereon which serve to rigidly connect the base with a cap 3 having an upstanding portion 4 through which extend openings 5. These opening run entirely through the head at different angles and are adapted to receive a handle bar 6 which may I be inserted therethrough. so as to constitute oppositely extending handles or which can be 5 placed successively in the ends of the open- I ings so as to make one-quarter or one-half l turns where the tool is located in a corner or other place which is not readily accessible. A stem 7 extends longitudinally from the center of the head 4 and constitutes a bearing for I a head 8, the outer end of which extends bei yond the stem. l A disk 9 is secured within the base 1 by means of set screws 10 or any other desired holding devices and this disk has an angular opening 11 in the center thereof in which are secured thread cutting dies 12 which may be of any desired form and which may be fastened in place in any preferred manner. An extension 13 is located upon the disk 9 and ing between the cutting dies and constituting a chip way.

Where it is desired to employ this tool for the purpose of cutting threads at points which are not easily accessible the tool is inserted between the article to be threaded and a suitable abutment, the head 8 being placed against the abutment, and the dies 12 upon the article to be threaded. The entire device with the exception of the head 8 is then rotated by placing the bar 6 successively in the openings 5 and during this rotation longitudinal pressure may be exerted up on the tool in any preferred manner. Should it be desired to use the tool as a jack, a bolt 15 having threads corresponding with those on the dies 12 is inserted into engagement with the dies and with its head below or beyond the base 1. The entire tool including the bolt is then placed between the two objects to be moved apart and by turning the base 1 by means of bar 6 in the manner hereinbefore described the dies 12 will rotate upon the bolt 15 and the head of said bolt will be moved away from the base thereby causing the two surfaces between which the tool is interposed to move apart. This tool will be found of considerable convenience to railroad men because of its compact nature and also because of the double use to which it may be placed.
