Specification of Letters Patent.

Patented July 15, 1919.

Application filed August 31, 1917. Serial N 0. 189,046.

To all whom it may concern:

Be it known that I, MEREDITH LEIToH, a citizen of the United States, residing at Poughkeepsie, county of Dutchess, and State of New York, have invented a new and useful Improvement in Machine Bases, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to bases or stools for machines. The object of my invention is to produce a readily manufactured, and rlgid, sheet metal machine stool.

The particular embodiment of my invention described herein is a base or stool for a centrifugal cream separator, but the same construction is suitable for many other machines.

Separator stools are usually made of cast iron and are, because of the impossibility of casting very thin sections, necessarily heavy and cumbersome.

Attempts have been made to make sheet metal stools by drawing from a flat blank, but the height and size are such as to require the use of long stroke powerful resses, thereby making the stool expensive.

When cast iron stools are used there are generally finished surfaces, on the bottom of the machine frame, that fit on top of a shelf which, in turn, fits on top of the stool, and a screw, passed through a hole in the center of the stool top and screwed into the bottom of the machine frame, clamps all together. The preferred embodiment of my invention is especially adapted for use in the combination.

In the accompanying drawings: Figure 1 is a side view of a cream separator having one of my improved stools. Fig. 2 is an inside view of one of the corner pieces. F ig. 3 is a section on the line 33 of Fig. 2. Fig. 4: is a part sectional view of the lower part of a separator frame, the upper part of a stool, the shelf between, and a crowfoot through which a bolt passes to secure all th parts together. Fig. 5 is a top view of one of the corner pieces. Fig. 6 is a view, simllar to Fig. 5 of a modification.

Separator frame a rests on a shelf 6, which in turn rests on a stool c. The stool comprises side plates d and angular corner pieces 0, which may be secured together by riveting or by electrical spot welding. The

corner pieces may be split down the bend at the top for a distance equal to the width of one side and bent over to form a doublethickness horizontal portion, as shown at f in Figs. 2, l and 5; or a V-shaped notch may be cut in the end and the two points bent down to form a jointed single-thickness horizontal portion 70, as shown in Fig. 6.

An inverted crowfoot g has its toes pressed upward against the under sides of The hori zontal portions at the tops of the corner pieces 6. A screw h, passed through a hole in the center of the crowfoot, enters a threaded socket in the bottom of the frame a and clamps all together.

In order to allow easy cleaning of the floor below the machine, the side pieces d of the stool are cut off, considerably above the floor, and the corner pieces are extended to form short legs and bent outward and spread apart to form feet at the bottom. The material of each corner piece is bent backward upon itself to give a double thickness foot as shown at 2', Fig. 2, and continued upward inside the lower portion of the side pieces as shown at 7' to reinforce and stiflen the leg and lower corner.-

The panel pieces cl, being formed without drawing, no press work, other than blanking and bending, is required. Because of the angular cross section and reinforced lower portion the corner pieces may be formedof light strips requiring only a low pressure to force into shape. The shape of each corner piece is one that will require only a short stroke press to form.

aving now fully described my invention, what I desire to claim and protect by Letters Patent is:

1. A machine stool comprising a series of upright panels of sheet metal and corner pieces uniting adjacent panels, each corner piece being of angular cross section with its wings secured respectively to the edge portions of adjacent panels and its upper ends cut and bent to form horizontal shelves overlying the panels.

2. A machine stool comprising a series of upright panels of sheet metal, and corner pieces uniting adjacent panels and extending above and below the same, the part of each corner piece extending below the panels being shaped to form a supporting foot and the part of each corner piece extending above the panels and being cut and bent to form a horizontal shelf overlying adjacent panels.

3. A machine stool comprising a series of panels of sheet metal and corner pieces uniting adjacent panels, each corner piece being of angular cross section, the lower ends of the corner pieces being bent and returned on themselves to form feet of double thickness, one lower corner of each panel being confined between opposing sections of one wing of an angular corner piece.

4. A machine stool comprising a series of panels of sheet metal and corner pieces uniting adjacent panels, each corner piece being of angular cross section the two wings of which extend outside of and are secured to the edge portions of adjacent panels, the lower end of each corner piece being bent and returned on itself to form a doublethickness foot, the lower adjacent corners of adjacent panels being confined between the two wings of the downwardly extending portion of a corner piece and the two wings of the upwardly extending portion thereof.

5. A machine stool comprising a series of panels of sheet metal and corner pieces of angular cross section, each corner piece extending outside of and secured to the edge portions of adjacent panels, the lower ends of the corner pieces being bent and'returned on themselves to form double-thickness feet and extending inside the panels and confining their lower corners between the clownward and upward bends of the corner pieces, the upper ends of the corner pieces being out and bent to form horizontal shelves.

6'. A machine stool comprising a series of upright panels of sheet metal, the upright edges of the panels curving outwardly toward their lower ends, and corner pieces of angular cross section adapted to conform, and secured, to the outside faces of the panels adjacent theircurved edges, each corner piece extending below said panels and bent and returned upon itself and secured to the inside faces of the panels adjacent their curved edges, the wings of the corner pieces adjacent the lines of bending being bent outward and spread apart and shaped to form double-thickness supporting feet.

7 In a machine support, the combination with a metal stool comprising panels and corner pieces, each corner piece having a horizontal portion at its upper end forming a shelf, an inverted crowfoot with its toes against the underside of the shelves, aframe resting on the shelves and having a threaded socket, and a bolt extending through a hole in the crowfoot and entering the threaded socket in the frame and clamping the parts together.

v8. A machine stool comprising a series of panels of sheet metal and corner pieces uniting adjacent panels, each corner piece being of angular cross-section the two wings of which extend outside of and are secured to the edge portions of adjacent panels, the lower end of each corner piece being bent and returned on itself, the lower adjacent corners of adjacent panels being confined between the two wings of the downwardly extending portion of a corner piece and the two wings of the upwardly extending portion thereof, the double thickness corner piece below the panels extending outwardly and the wings thereof being spread apart toward approximately the same plane to provide a foot having an approximately fiat horizontal extremity extending out-- w-ardly.

9. A machine stool comprising a series of side panels, and corner pieces of angular section secured to the panels, eachcorner piece at its lower end being bent outwardly and thence returned upon itself, whereby its lower end portion is composed of two wings each of double thickness, the two win s at their lower ends being spread apart to orm an outwardly extending approximately flat foot of double thickness and of a width corresponding to the combined widths of the two wings. 1

In testimony of which invention, I have hereunto set my hand, at Poughkeepsie, N. Y., on this 24th day of Aug, 1917. e
