UNITED STATES PATENT OFFICE.

MARSHALL J. ROOT, OF WOONSOCKET, RHODE ISLAND, ASSIGNOR TO AMERICAN WRINGER COMPANY, INC., A CORPORATION OF RHODE ISLAND.

WRINGING MACHINE.

My invention relates to clothes wringing machines and is especially directed to devices Vtor mounting or supporting the same upon various articles.

The essential objects of my invention are to facilitate the reversal of position of the mounting devices; to permit such reversal without complete detachment ot the mounting devices from the machine and with a minimum number of motions; to maintain the devices against accidental separation from the machine under excessive transverse strain; to atta-in these ends in a compact and inexpensive structure.

lVith the vabove and other objects in view, all ot' which will fully appear in the course of the vfollowing description, my invent-ion consists in the means tor producing lthe purposes and results above specified substantially as hereinafter claimed.

In the accompanying drawings which are a part o't this specification, and in which is shown merely a preferred form of embodiment of my invention,

Figure l is a side elevation of a wringing machine in which my invention is embodied,

Figure 2, a. rear elevation of the same, with a part thereof broken away,

Figure 3, a fragmentary side view of the saine, partly in section, showing a bracket partially disengaged,

Figure 4, a fragmentary side elevation of the machine with the bracket in a second or adjusted position, and

Figure 5, a section on line 5 5 of Figure 1.

Like reference numerals indicate like parts throughout the views.

The invention will be described in connection with the specific embodiment shown, and it will be understood that the invention is not to be limited by such specific showing except tor such limitations as the claims impart.

My inventionis herein illustrated in conjunction with a metal frame wringing machine whercin the rolls 8, roll shafts 9, bearing blocks 10, and cross piece 11, of common construction are supported in the side bars or members 14 of the trame. members 14 comprises a vertically disposed body portion 15 and an inclined base portion 16, having upon its lower end a bearing face V17 upwardly inclined relatively to the body portion 15 provided with a longitudinal Each of the Serial No. 290,460.

groove 20, substantially angular transversely, as shown in Figure 5. A smooth inclined hole 22 extends from the center of the bearing face, at right angles thereto, upwardly through the top of an offset part 23 of the base portion.

A clamping bracket is attached to each member 14 and comprises an oblong body 24 having top and bottom faces 26 and 27 respectively substantially parallel with each other, and disposed at right angles to its sides 28 and ends 29. The top bearing face 26 is provided with a longitudinally disposed rib 31 adapted to register' in the groove 26 in the face 17 of the member 14. The body 24 is provided centrally with a bore 33 disposed at right angles to the top face of the body, and in alignment with the bore 22 to loosely receive a swivel bolt 35 eX- tending loosely through the holes 22 and 33, and whose head 36 is seated in a recess 37 in the bottom face 27 of the body. This bolt constitutes a shaft around which the body 24 is swiveled in changing it from the full lines to the broken line position shown in Figure 3 or vice versa. The threaded portion' 39 of the bolt projects above the top or' the offset portion 23 of t-he base portion 16 of the member 14, and is engaged by a clamping nut 41 adapted to retain the members 14 and 24 tightly together or release them a sulicient distance from each other to permit swiveling of the member 24.

Integral with the bottom portion of one end of the. body 24 is an arm 43 disposed at an obtuse angle relatively to the top of the body. Integral with the corresponding portion of the opposite end of the body is the inner member 44 of an angular arm 45 whose outer member 46 is disposed at right angles to the member 44, and lies in the plane ot its companion arm 43, parallel with the latter. The member 46 carries a set screw or clamping screw 48 adapted to cooperate with the bearing arm 43 to clamp the object to be engaged. The member 44 is also disposed obtusely to the top of the body. As seen in the drawings the top 26 of the body is disposed angularly relative to the arms 43 and 45, but neither of these two arms at any time contact with any part of the end member 14.

In applying the machine to a bench, table or tlgiei horizontal object 49, the arms 43 and members 46 are, as shown in Figure l, disposed horizontally with the clamping screws 48 in engagement with the object 49.

If it is next desired to apply the machine to a vertical object, such as a tub 50, as shown in Figure fl, the nuts l-l are turned a sufficient distance to permit the brackets, as shown in Figure 3, to clear the members 14, whereupon the brackets are manually swiveled a. semirotation to bring the arm f3 andv member 46 into reverse position indicated in broken lines in the latter ligure. The clamping screw 48 is next engaged with the't-ub 50. rIhe nuts il are now finally turned, which draw the faces 26 of the bracketsy into tight engagement with the@ faces 17 of the member lll, and the ribs 3l into the grooves 2U.

It will be observed that the change of the machiney from a horizontal to a vertical object, or vice versa, is effected without requiring the complete detachment of the brackets fiom the end members 14 of the machine, and embody a less number of parts than are required by a universal joint construction. The tongue and groove construction furnishes an auxiliary means for preventing accidental swiveling of the brackets under excessive shock or strain.

I claim f t l. In a wringing machine, a side bar provided at its lower end with an oblique bearing face, a bearing member having a beaiing face engageable with the first face, arms extending vfrom the bearing member disposed obliquely to the faces and directed away from the faces, said arms being provided with substantial parallel portions said member at an angle to said faces for engagement with the side bar.

2. In a wringing machine, a side bar comprising a vertical body portion, and an inclined base portion offset at its top from the body portion and provided upon its bottom with a bearing face parallel with said top and obliqucly disposed relatively to the body portion and provided with a bolt receiving hole extending from the offset top of the base to the face at right angles to the latter, a bearing member having a face coinciding with the first face and provided with a bolt receiving opening disposed at right angles to both faces, a bolt inthe hole and opening, a head upon one end of the bolt, a clamping nut upon the other end of the bolt engaging the offset top of the base, and clamping arms upon the bearing member disposed obliquely to the faces.

3. In a wringing machine, a side bar formed with an oblique bearing face, an

oblong bearing member provided with a bearing face upon its top engageable with the first face, one of said faces being provided with a groove, a rib upon the other of said faces registerable in the groove, obliquely disposed clamping arms upon the bearing `member directed away from the faces, and a bolt swivelly mounted in the side bar and bearing member. l

In testimony whereof I have affixed my signature.

MARSHALL J. RGUT.
