JOHN FJS'lEDIE'IAIT, OF TIGARD, OREGON.

TOOL-SUPPORTING STAND.

Application filedvli'iarch 20 To U whom it may concern: I

Be it known that 1, JOHN F. STEDMAN, a citizccn of the United States, residing at Tigard, in the county of -i i ashington and titatebf Oregon, have invented certain new and useful Improvements in 'lool-Supporting' Stands. of which the following is a specification.

The stand which is the subject matter of the present application for patent has been designed more particularly for supporting .in operative position a manually guided and controlled power-driven band saw used by butchers, or any other tool which is to be suspended from some overhead support.

The invention has for its object to provide a novel and improved portable stand of the kind stated. by the use of which the saw or other tool can be easily guided relative to the work. and also to provide a counterbalance for the tool to facilitate the vertical adjustment thereof.

With the object stated in view, the invent on. consists in a combination'and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing wherein:

Figure 1 is an elevation of the stand; Fig. is an enlarged central vertical section hereof partly broken away, and Fig. 3 is horizontal section on the line 33 of Referring specifically to the drawing, 5 denotes a standard rising to a suitable height from a. base plate 6. The standard is tubular so that it may house a counterweight 7. The base plate has a top boss 8 into which the lower'end of the standard is screwed, and said plate is carried by a base frame consisting of a pair of parallel and laterally spaced angle bars 9 connected across at their ends by angle bars 10 extending outward from one side of the frame, and mounted on rollers 11 to facilitate transportation of the stand. it being understood that the stand is portable.

To the upper end of the standard 5 is fastened an extension 12 of reduced diameter. the standard being thus made in two sections. The connection between the sections may be made by a screw joint as shown in 2. The section 12 is shouldered externally at the bottom as shown at 13, which is for a purpose to be presently described.

The standard section 12 pivotally supports 1922. 1 Serial No. 545,119.

a bracket arm let-extending outwardly and horizontally therefrom. The inner end of thisbracket arm 14 has a hub15 which fits rotatably on the standard section 12 so-that the bracket arm may be freely swung'in a horizontal direction. A thrust and radial bearing 1611's provided between the standard section l2 and the bracket arm .hub15ysaid bearing engaging the shoulder13. Atthe top there is interposed between the standard section and the hub. a roller or otherantifriction bearing 16 To prevent upward displacement of the bracket arm, there is screwed on the upper end of the standard section above the top of the hub 15 a cap 17. The standard section 12 is also tubular, and open at the top as well as at the bottom to permit the passage thereinto of a flexible cord. cable, chain or other suspension device 18, the same passing down into the standard section 5 and carrying at its lower end the counterweight 7.

The swinging bracket arm 14 carries guide pulleys l9 and for the suspension line 18. the pulley 19 being'located at the inner end of the arm to guide one end of the line downwardly into the standard sections 12 and 5. and the pulley 20 being located at the outer end of the arm to guide the other end of the line downwardly from the arm,

' this end carrying the saw or other tool 21.

The angle bars 10 of the base frame extend in the same general direction as the bracket arm 14- to impart the necessary stability to the stand.

A means is also provided for limiting the swing of the bracket arm 14, the same being a lire; or finger 22 depending from the bottom of the hub 15. and located between a pair of abutments 22 extending outwardly from the lower end of the standard section 12. These abutments may be screws, and the standard section 12 has a number of tapped holes so that the position of the screws be varied.

If the stand is to support a meat saw 21 as shown. it will be placed alongside a block 23 or other support for the meat to be operated on. so that the saw will be properly located above said block.

In operation, the bracket arm 14 swings freely to follow the saw or other tool suspended therefrom by the line 18, and as the tool is counterbalanced it can be elevated and lowered with but very little effort on the part of the operator.

I claim:

1. A tool supporting stand comprising a base, a stationary hollow standard rising from the base and having a hollow top extension which forms a bearing, a horizontal bracket arm having a hub at its inner end which is rotatably supported by the bearing, guide pulleys carried by the bracket arm,

' one of said pulleys being located above and at the outer end of the bracket arm, and the other above and at the hub, aflexible tool supportingline passing over the pulleys and having its vends depending therefrom, one end passing through the top extension of the standard and also into the standard, and the other end being adapted to support a tool, and acounterweight housed in the standard, said counterweight being attached to the first-mentioned end of the line.

2. A tool supporting stand comprising a base, a stationary hollow standard rising from the base and open at its upper end, a bracket arm extending laterally from the upper end of the standard and pivotally supported thereby to swing in a horizontal direction, means for holding the bracket arm against movement on the standard in the direction of the length thereof, guide pula leys carried by the bracket arm, one of said pulleys being located above and at the outer end of the arm and the other above and at the inner end of the arm, a flexible tool supporting line passing over the pulleys and having its ends depending therefrom, one end passing'into the'standard, and the other end being adapted to support a tool, and a counterweight housed in. the standard, said counterweight being attached to the firstmentioned end of the line.

In testimony whereof I afiix my signature.

JOHN F. STEDMAN.
