GEORGE STBONER AND WILLIAM C. BUEGE, OF GLOBE, ARIZONA TERRITORY.

'roon-nonnnn.

of Arizona, have invented new and useful, Improvements in Tool-Holders, of whichthe following is a specification;

T 's invention relates to improvements in that style of tool holding devices commonly known as the old man, which is used for holding drills in place during the operation of drilling holes in metal, such as iron gird- 817$ 01.- the like, the primary object of the in- Vention being to dis ense with the bolt means heretofore emplbyed for feeding the drill to its work and in lieu thereof to provide a simple and effective attachment whereby the device may be quickly attached to and held in position for work.

lVith the above objects in view, and others which will appear ast-he nature of the in, vention progresses, the improvement resides i th n vel construction and arrangement of parts hereinafter fully described and claimed. In thedrawings accompanying this specification, there has been illustrated a simple andprcferred embodiment of the invention,-

and it is to be understood that the showing therein is merely illustrative and that changes in the minor details as to size, shape, proportion, material, -etc., which fall within the scope of the appended claims, may be resorted to if desired.

In the drawings,Figur-e 1 is a perspective view of the improvement showing the same sustaining a'n electric drill. Fig. 2 is a side elevation illustrating the manner'of positioning the holder upon an irregular surface. Fig. 3 is a top plan view of the improvement.

' The present invention is adapted for use in the connection of drilling rivet holes in metal plates of any description, such as in building constructions, the sides or floors of war vessels, etc.

In the drawings, the numeral 1 designates the foot of the old man or tool holder. The foot 1 extends in opposite directions from its stem 2, and secured to the said foot, through the medium of a ball and socket joint 3, is a pair of electroInagnet-s 4. It is to be undcrstood that while only two of the magnets have been illustrated in the drawings, any number. of the same may be employed if desired. The stem pro ects I Specification of Letters Patent. Application filed m 12, 1911.; Serial No. 626,755.

I from an opening formed in the top plate or 2 project is bifurcated for a suitable dis- 4 tance andpivoted to the arms formed by the said bifurcations are

c'am levers

8 and 9. By this arrangement it will be noted that the arm 6 maybe independently adjusted and sustained in said ad usted position upon either the stem 2 or the fulcrum member 7 or both the said stem and member if desired.

The numeral 10 designates the head for the arm 6 which is arranged at one end thereof, and that opposite the fulcrum member 7'. This head 10 is provided with a suitable depression which isadapted to receive the upper cone shaped stemportion 11 of the drill 12. The drill illustrated in the drawings is electrically operated, but it is to be understood that any ordinary drill may be employed if desired. The stem 6 is provided with the usual operating wheel or handle, whereby the drill12 may be fed to its work.

From the above description, taken in connection with the accompanying drawings, the simplicity of the device, as well as the advantages thereof, will it is thought, be

perfectly apparent to those skilled in the art to which such inventions appertain without further description, it being noted that by providing the head llwith' the ball and socket joints 3 the electromagnets may be sustained at an angle to the remainder of the structure and that the fulcrum member,

Having thus fully described the said in- 4 cntion, what We claim is 1. A support for the purpose set forth comprising a head, said head having ball and socket joints, electromagnets secured to the ball and socket joints, a stem connected with the head, an arm having openings, the

said stem adapted to project through one of the openings, means for adjustably securing the stem upon the arm, a fulcrum member passing through the second opening of the arm, means for adjustably securing the fulcrum member upon the arm, and the arm being formed with a head, substantially as and for the purpose set forth.

2. In a support for the purpose set forth, a head having ball and socketjoints, electromagnets connected with the ball and socket joints, a stem connected with the head, an

- arm, said arm being arranged at an angle to the stem and being provided with a pair of spaced openings, the stem being adapted to pass through one of the openings, a pivoted cam lever carried by the arm and adapted to cause the arm to engage the stem, a fulcrum member passing through the second member, a cam lever connected with the arm and adapted to cause the. arm to engage with the fulcrum member, and the said'arm 20 ,GEORGE STRONER.
