MANUAL SUPPORT FOR PORTABLE TOOLS Filed Dec. 5, 1930- 6 INVENTOR.

flab/0i 1457027 5472 BY Patented Oct. 18, 1932 UNITED STATES PATENT OFFICE ADOLPH ANDERSON, OF LA GRANGE, ILLINOIS, ASSIGNOB 'IO INDEPENDENT PNEU- MATIG TOOL 00., OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE MANUAL SUPPORT FOR PORTABLE TOOLS Application filed December 5, 1930. Serial No. 500,209.

This invention relates to a manual support or handle for portable power driven tools or machines such as are designed for rubbing, polishing, sanding and the like.

Tools or machines of this character are designed to be held in the hands of the operator and with the handles or supports heretofore employed, the operator has not been able to conveniently hold the tools in any and all positions which may be required to reach the lay of the work or apply the required pressure on the tools in any and all such positions.

The main. object of this invention is to provide a handle or support for tools of this character with the handle or support completely surrounding or encircling the tool and in outward spaced relation thereto, so

that the operator may readily change the position of his hands about the tool to conveniently hold the tool in the position required by reason of the lay of the work, and also to apply pressure to any part of the circumference of the polishing or sanding wheel.

Specifically, the handle or support of my invention is annular in shape, and resembles somewhat the shape of an automobile steering wheel, surrounding the tool in outward spaced relation thereto and connected with the outer casing 01": the tool by suitable connecting members which may be likened to the spokes of a steering Wheel.

With the handle or support capable of surrounding the tool and larger in diameter than the outer casing of the tool, the handle may be located approximately at the center of gravity of the tool, so that the tool will be in balance and thus permit the tool to be held in all positions required without undue strain or burden on the operator.

The invention consists further in the matters hereinafter described and claimed.

In the accompanying drawing:

Fig. 1 is an outside view, with parts in section, of a portable electric polishing machine provided with manual support or handle in accordance with my invent-ion; and

Fig. 2 is a bottom plan view taken on line 2 2, of Fig. 1.

In the drawing, Ihave shown my invention applied to aportable electrically operated polishing machine, having an outer casing 1 to the upper end of which is connected the conduits by which the current is supplied to the motor within the casing of the tool. The spindle 2 of the tool extends out of the casing 1 .at. its lower end, and has secured thereto a polishing wheel 8 arranged at right angles to the spindle as in tools of this character.

In accordance with my invention, the manual support or handle for the tool is in the form of an annular member 4 disposed to completely surround the outer casing 1 of the tool intermediate its ends, preferably at a point which is approximately at the center of gravity of the machine, this being adjacent the lower end of the outer casing 1 as shown in Fig. 1.

The handle 4 has a diameter considerably larger than the outside diameter of the easing 1, and is secured to and spaced outward therefrom by a number of brackets 55, which as shown in the drawings, are preferably in the form of metal strips bent upon themselves intermediate their ends to provide loops 6 which surround the tubular handle member l. The remaining portions of the strips extend inward toward the outer casing 1 of the machlne and are secured thereto by bolts '7,v

as shown. These bolts may be the same bolts which secure together the motor and gear case sections 8, 9 of the outer casingl, as indicated in Fig. 1. '[The brackets 5 are secured to the under side of the outwardly extending flange portionlO of the gear case section 9, and extend outward and upward from this section at the inclination shown, so that the annular member 4: of the handle or support will be disposed in a plane substantially parallel to that of the wheel or at right angles to the axis of the tool and be positioned at the point desired to balance the machine by having the handle located approximately at the center of gravity of the machine.

The brackets 5 are long enough to space the handle member 4 far enough outward from the housing of the machine to leave ample room for the hands of the operator when a loop 6 of one of the brackets 5, as indicated at a in Fig. 2.

The handle member 4 when in tube form is usually made of metal, although it can be made in solid form of wood or fiber, if desired, The brackets 5 may be secured to the handle member 4 in any manner desired, it

being only necessary to properly support the handle member in spaced relation to the outer casing of the machine and in the position described.

With the handle member completely surrounding the machine, the operator may grasp the handle at any point or points in its circumference, and thus locate his grip to that most convenient for holding the machine in different positions. Moreover, with the handle member encircling the machine and arranged substantially parallel to and above the polishing wheel 3, the operator, by changing the positions of his hands above the handle, can apply the desired pressure to any part of the circumference of the polishing wheel. In polishing automobile bodies, for instance, or any other kind of polishing where the machine has to be held in all kinds of po- I sitions, the type of handle member described 1s very convenient as it adapts itself to cliffe-rent positions of the hands of the operator.v My improved handle can be applied to other types of machines, and I do not wish to limit it to polishing machines, as shown.

I claim as my invention:

1. In a portable motor operated tool of the .class described having an outer casing containing the motor of the tool. a handle member surrounding the outer casing, and brackets connecting the handle member with the outer casing and maintaining the handle member in outward spaced relation therefrom, said brackets each comprising a strip secured at its inner end to the casing and having a bent portion at its outer end to surround and engage the handle member.

2. In a portable motor operated tool of the class described having an outer casing containing the motor of the tool, a handle mem- ADOLPH ANDERSON.
