JOHN F: GILL United States Patent 3,402,908 BASE FOR SUPPORTING DRILL PRESSES ON COLUMNS John F. Gill, 1255 Fairlane Ave., Brookfield, Wis. 53005 Filed July 18, 1966, Ser. No. 566,448 2 Claims. (Cl. 248-231) ABSTRACT OF THE DISCLOSURE A portable base support adapted for engagement with the vertical portions of a tubular scaffold including a vertical angle iron adapted to lodge against the tubular member, a chain element fixed by one end to the angle iron and utilized to embrace said tubular member, and adjusting means for tightening said chain.

This invention relates to improvements in base supports, and more particularly to a novel base for supporting drill presses on columns such as tubular scaffolds or the like.

During construction work it is often necessary to use a tool or other instrumentality requiring a stable support such as a drill press, and there is commonly no convenient place or means of securing such a tool. Also in construction work, the use of tubular scaffolding is very common, and it is the object of the present invention to provide a convenient and efficient base support for a drill press or the like which will be stable when releasably secured to a column of a tubular scaffold. A further object of the invention is to provide a vertical angle member as a base to be lodged against a vertical member of a construction scaffold, with a chain element secured to adjustable means by one end for tightening said chain, the latter being passed about said vertical scaffold member with its opposite or free end being releasably held in a notch in a member secured to said vertical angle base member.

Other and further objects of the invention will appear as the description proceeds, reference being had to the accompanying drawing, in which:

The drawing is'a view in perspective of a base for supporting drill presses on columns, a portion of a column on which it is mounted being shown in elevation.

Referring more particularly to the drawing, the numeral refers to a vertical column as in a tubular scaffold assembly. A heavy angle iron 11 is lodged against the column 10 and held in place by means of the chain element 12.

A pair of relatively smaller

angle iron members

13 and 14 are brazed or otherwise secured to and project beyond one segment of the angle iron 11 on the outside thereof, and serve as keepers for the solid shaft member 15 which is bored at 16 to accommodate the threaded element 17 which is engaged at one end 18 with the chain 12. On the opposite segment of the angle iron 11 is a relatively small ice angle iron 19 disposed on the outer face of said segment and notched at 20 to facilitate binding of the chain 12 therein. The threaded element 17 is provided with a nut 21 which may be taken up to releasably secure the angle iron 11 on the vertical column 10 by increase to maximum tension of the chain element 12 as it embraces the column 10. A bar 15a extends upwardly from the back of the angle iron 11 integral at its upper end with a knurled stationary member 22 secured by releasable means 23 to a similar knurled element 24 on an end of member 25.

On the opposite end of member 25, a similar knurled element 26 is releasably fixed to knurled element 27 which latter is aflixed to standard 28 provided with the base 29 for a drill press or the like.

It will be understood that the device is capable of many modifications in structure and design, without departing from the spirit of the invention, within the scope of the appended claims.

Having thus described the invention, what is claimed and desired to be secured by Letters Patent of the United States is:

1. A portable releasable base support comprising a length of angle iron adapted to be lodged against a column of a tubular scaffold, a chain element for embracing said column, a pair of angle irons, smaller than said first mentioned angle iron spaced exteriorly on one segment of said larger angle iron, a solid cylindrical element normally held within said smaller angle irons the latter being keepers therefor, another angle iron disposed centrally and exteriorly of the other segment of said first mentioned angle iron having a central notch therein registering with a like notch in said first mentioned angle iron segment, a threaded element passed through a transverse bore in said solid cylindrical element and attached by one end to said chain element, the free end of said chain element being adapted to the aforementioned notches, and a nut on said threaded element for drawing up the chain about a column.

2. A device as in claim 1 having an upstanding element above and fixed to said large angle iron, a knurled circular portion fixed at the top of said upstanding element, a second circular knurled portion releasably fixed by threaded means thereto, an arm integral with said second circular knurled portion, and means at the free end of said arm for releasably adjustably securing the base of a drill press.
