Patented Sept. 17, 1929 UNITED STATES ARTHUR R. CURTIS, OF CLEVELAND, OHIO WASHER Application filed April 23, 1923.

: member in such a manner that the removal of the cylinder from the tub and the insertion of the cylinder into the tub is greatly facilitated.

A further object is to provide means for effectually protecting the wall of the tub against denting and scratching by the trunni on of the cylinder as the cylinder is removed from or inserted into the tub.

A further object is to provide a closure member for the opening in the cylinder which is securely held in place and ils effectively protected against distortion.

The above and other objects which are obtained by the present invention may be briefly summarized als consisting in certain novel details of construction and combinations and arrangements of parts which will be described in the following specification and set forth in the appended claims.

Reference should be had to the accompanying drawings forming a part of this specification in which Fig. 1 is a central vertical section lengthwise of the tub and cylinder, the section being slightly offset at one end of the cylinder to show the connection between the cylinder and driving head; Fig. 2 is a fragmentary transverse section through the cylinder; Fig. 3 is a top plan view of the cylinder with the hinged closure at the top;

Fig. 4 is a fragmentary perspective view showing the trunnion receiving socket and valve operating strap guided thereby; Fig. 5 is a fragmentary perspective view of the driving head at the end of the cylinder drive shaft; Fig. 6 is a fragmentary perspective Serial No. 633,970.

vienT of the end of the cylinder which engages the driving head on the drive shaft; Fig. 7 is a fragmentary vertical section showing the manner in which the tub cover may be hung upon the side of the tub; Fig. 8 is a fragmentary end elevation of the portion of the cylinder which carries the latch bar; Fig. 9 is a section on line 9 9 of Fig. 8.

Referring to the accompanying drawings, the tub 1 which is rectangular in horizontal cross-section is carried by a supporting frame 2 preferably formed of light angle iron. The upper edge of the tub is provided with outwardly extending flanges 3 which rest upon the horizontal flanges of top rails 4 of the supporting frame and are suitably secured thereto. Within the tub 1 is a rotary cylinder 5 which is detachably supported at one end upon an open top socket member 6 secured to one end of the tub and at its opposite end upon a driving head @which is fixed to the end of a horizontal drive shaft 8 which extends through the wall of the tub. The cylinder 5 is bodily removable from the tub and is preferably rotated alternately in opposite directions by means of an automatic reversing gear within the casing 9 at the end of the tub, the cylinder being driven through the reversing gear by means of a suitable motor 10 carried by the supporting frame.

As shown in Fig. 5 of the drawing, the driv` ing head 7 has a pair of diametrically opposite driving lugs 11 and 12 extending therefrom and projecting beyond the inner face of the head 7. The lugs 11 and 12 engage with suitable sockets formed in the adjacent head of the cylinder as will be hereinafter explained.

The cylinder 5 has

heads

13 and 14 at the ends thereof which are formed of sheet metal and have peripheral outwardly extending flanges l5 and 16. Reinforcing plates 17 and 18 are secured upon the outer faces of the

heads

13 and 14 at the central portions thereof to stiffen the supporting portions of the heads. A trunnion 19 is rigidly secured to the center of the head 13 and serves to support this end of the cylinder in the socket member 6 carried by the end of the tub.

In the opposite head 14 apertures 20 and 21 one head thereof` to the other.

are provided through the head 14 and reinforcing plate 18 to receive the driving lugs 11 and 12.

Tongues

22 and 23 are provided upon one side of the apertures 20 and 21 and project outwardly fromthehead, said tongues being adapted to engage one face of the driving lugs 11 and 12. Tongues 24 and 25 which are shorter than the

tongues

22 and 23 are provided upon the opposite sides of the apertures. As shown in the drawings, the

long tongues

22 and 23 are upon the upper sides of the apertures on the side toward the hinged closure member of the cylinder7 the driving mechanism being preferably so arranged that when the cylinder is stopped, the hinged closure member will always be at the top. The

tongues

22, 23, 24 and 25 are preferably punched out of the body of the cylinder head 14 and .project through the registering opening in the reinforcing plate 18.

The body of thecylinder has a fixed portion 26 of perforated sheet metal which is rigidly attached to the

heads

13 and 14 and extends throughout the greater portion of the circumference of the cylinder but has its ends spaced apart to provide an opening which extends longitudinally of the cylinder from The fixed portion 26 of the body has its opposite edges overlying the flanges 15 and 16 of the

heads

13 and 14 and bent back over these fianges to secure the heads thereto. The fixed portion 26 of the cylinder body has regularly spaced reentrant portions 27 which form inwardly projecting ribs or baffles. The

heads

13 and 14 have notches extending inwardly from the periphery thereof to receive the reentrant portions 27 of the cylinder body, the heads being flanged along the edges of the inward' ly extending notches and the edges of the body in the reentrant portions thereof overlying these fianges and bent back to interlock therewith, the interlocking edge and fiange being bent back against the head to form a double seam 2,7a along a portion of the edge of the cylinder body. The double seam 27 serves to lock the heads against inward movement with respect to the cylinder body so that the heads are rigidly locked to the body. The reentrant portions 27 of the cylinder body provide a rigid reenforcement for the

sheet metal heads

13 and 14 and the double seams 27a along the edges of the notches rigidly interlock the head to the reentrant portions of the body so that the head is held rigidly against both inward and outward movements with respect to the body. As clearly shown in Fig. 8 the outer ends of the double seams 2,7a abut against the edge portions of the cylinder body which are turned back over the outwardly extending fianges 16 of the heads so that the peripheral standing seam connecting the cylindrical portions of the body to the peripheral edges of' the heads is locked against spreading open at the ends of the seams terminating at the notches. The longitudinal opening of the cylinder is closed by a segmental sheet metal ciosure member 28 which is pivoted along one edge to an end of the fixed portion 26 of the cylinder body. The closure member 28 has integral inwardly extending side flanges 59 which lie closely adjacent the

heads

13 and 14 and an inwardly extending flange 60 along its free edge which is formed by bending the edge of the closure member inwardly' and back upon itself. The closure member 28 is connected along one longitudinal edge of the opening by means of hinge strips 29 and 30 secured to the fixed body portion 26 and to the edge of the closure member 28 respectively. The hinge strip 29 has a portion lying fiat against the fixed portion 26 of the body at the end thereof and is formed with an olutstanding rib or flange 31 which is preferably formed by bending the strip 29 outwardly and back upon itself. The edge of the cylinder Mening to which the closure member 28 is hinged being at some distance from a reentran portion, the hinge strip 29 is made ihe form of' an angle bar to reinforce and "fen the edge to which the closure member is hinged. The edge of the strip 29 toward the opening is provided with hinge pin receiving knuckles 52 at the ends thereof directly over the opposite heads '13 and 14 and with intermediate spaced hinge pin recoin ing knuckles rllhe hinge strip 30 carried by the closure member 28 is provided along its outer edge with hinge pin receiving knuckles 84 which fit between the knuckles of the hinge strip 29 on the fixed portion of the body. A hinge pin 35 extending the full length of the cylinder passes through the interfitting knuckles of the hinge strips 1 29 and 30. rl`he end of the fixed portion 26 at the edge of the opening with which the free edge of the closure member engages is provided with a reentrant portion 27 adjacent the opening, the edge portion of' the fixed part of the cylinder between the reentrant portion 27 and the opening is bent back radially upon itself and the bent back portion is curved forwardly to provide a ledge 36 upon which 'the inner edge of the flange 60 of the closure member rests when the closure member is in closed position. The closure membr 28 has a curvature the same as other portions of' the cylinder and when in closed position completes the cylindrical body of the cylinder. For securing the closure. member 28 in closed position an angie latch bar 37 is provided which extends the full length of the cylinder and has a fiange 88 adapted to overlie the free edge of the closure member 28 and an inwardly extending flange 39 which extends into the reentrant portion 27. The flange 39 has at each end an extension 39d which is bent at right angles thereto and overlies the opposite neads of the cylinder.

The portions 39a extend over the double seams 27a connecting the reentrant portion 27 to the cylinder heads and has an inturned end portion 39b which is engage-able with the seam 27a to limit the outward movement of the latch bar. The latch bar 37 is resilientiy supported by means of a pair of spring straps 40 which are secured to the flange 39 of the latch bar and to the cylinder body adjacent the inner end of the reentrant portion 27. The closure inei'nber 28 is provided ad jacent its free edge and centrally thereof with a handle 41 by means of which it may be opened or closed. The latch bar 37 has a handle 42 attached to the central portion of the flange 38 by means of which the latch bar may be swung away from the closure member to release the saine. The stop flanges Bill at the ends of the latch bar 37 limit the outward movement of thc latch bar and prevent excessive movement thereof which might cause the supporting straps 40 to become distorted. During the closing morcinent of the closure member the face of the inwardly extending flange (5() at the frcf: edge thcreofengages the inneredge ofthe flang` 23S of the latch bar and forces the latch bar cles. r of the opening to permit the closure member to pass into closed position whereupon the latch bar will spring back into locking position. To remove the cvlinder from the tub the end of the cylinder carrying the trunnion 19 is tilted upwardly to a slight extent, causing the lower tongues 24 and 25 to be swung clear of the driving lugs 11 and 12 so that the cylinder may be lifted bodily in a vertical direction. lVhen the cylinder is inserted into the tub, the closure member 28 is preferably opened so that the operator can look through the openings 20 and 21 in the head 14 and see when these openings are properly positioned with respect to the driving lugs 11 and 12. The cylinder is lowered with the end which engages the driving head 7 slightly lower than the other end so that the short tongues 24 and 25 will readily pass the lugs 11 and 12 while the

long tongues

22 and 23 will drop upon the top surfaces of the lugs and prevent further movement of the cylinder. The open socket member 6 is provided with inclined sides 43 which serve to guide the trunnion 19 to the central seat portion of the socket. The upper edge 44 of the back portion of the socket member 6 is beveled so that if the trunnion engages the back portion of the socket, it will be guided forwardly into the central pocket.

In removing the cyliinler from the tub and inserting the cylinder into the tub, the cylinder trunnion is likely to strike against the end wall of' the tub :ind dent or scratch the same. To protect the end wall of the tub, I have provided a vertically sliding bar or strap 45 which lies flat against the end wall and is guided between the end wall and the central portion of the socket member 6. The vertically movable strap 45 extends vertically across the axis of the cylinder and will be engaged by the trunnion 19 in case the cylinder is moved toward the end wall as it is moved to or from its supports. The strap 45 also serves to control the drain outlet 46 in the bottom of the tub which is located adjacent the end of the tub upon which the strap 45 is mounted. The outlet 46 is adapted to be closed by a valve in the form of a plug 47 attached to the lower end of the strap 45. The strap 45 extends to adjacent the top of the tub and is provided with a handle 48 which extends through a slot 49 in the end l..

wall of the tub adjacent the top thereof. The tub is provided with a cover 50 in the form of a flat plate which is provided with flanges 51 on its underside which extend along the edges and are spaced inwardly from the fupwardly. When the cover is removed from the top of the tub, one of the edge flanges 51 may be slipped over the supporting lugs 52 suspending the cover 50 in vertical position on the side of the tub.
