While a preferred embodiment of the invention is illustrated in the drawings, it will be understood that minor changes and modifications may be made in the particular construction shown and the invention may be embodied in other forms as will appeal to those skilled in the art and falling within the scope of the appended claims without departing from the spirit of the invention.

Referring to a detail description of the particular embodiment of the invention illustrated in the drawings, A generally designates a supporting stand and casing having a base l9 and walls 29 extending upwardly from opposite sides thereof connected by a front wall 21, the base I9 and the forward reduced portions of the side walls 29 extending, as shown, forwardly of the front wall 2 l.

Supported on the side walls 29, at the upper ends thereof, is an auxiliary frame 13 having thereon two bearings 22, in which is supported for rotation a shaft 23. Rotary movement is imparted to the shaft 23 by an electric motor (not shown) mounted within the lower part of the stand or casing A, through driving means including a gear wheel 24 fixed on the shaft 23 between the bearings 22 meshing with a smaller gear wheel 25 on a shaft 26 on the forward end of which there is a pulley 21. The driving means, which includes other elements, not shown, and the construction of the auxiliary frame B, as well as the construction of the supporting stand and casing A, are the same in construction as that disclosed in our application Serial No. ,623.

The shaft 23 projects forwardly from the front wall 2! of the supporting stand or casing A, and, on this end of the shaft, is mounted the vessel carrier 28, the same being of disc-like form adapted to carry at the front side thereof a plurality of tumbling essels 29 of various sizes and shapes, each individually detachably secured at one end on the carrier. In accordance with the present invention, the vessel carrier 28 is connected with the projecting end portion of the shaft 23 so that it is disposed forwardly of the end of the shaft with its central part spaced therefrom whereby substantially the entire face of the vessel carrier is left free for the mounting of tumbling vessels thereon. This .connecting means includes a metal disc 30 fixedly secured on the end of the shaft 23, and a plurality of studs 3| on the vessel carrier 23 projecting from the rear face thereof at points outwardly of the central-part of the same, and having their outer threaded end portions 52 extending through apertures 33 in said disc, said studs each having an intermediate enlarged portion 34 interposed between the rear face of the vessel carrier 28 and the disc 30.

On the outer threaded end portions of the studs are nuts '35., The studs 3| have reduced inner end portions 36 fitting in apertures 3! in the vessel carrier and secured by welding thereto. The disc 39 is shown provided with a central opening 38 receiving the projecting end portion of the shaft 23 and is secured by welding to the shaft.

For the sake of clearness, only two tumbling vessels or containers 29 are shown attached to the vessel carrier 28 in Fig. l of the drawings. It will be understood that the invention comprehends havingtumbling vessels attached'to the vessel carrier 28 all about the front face thereof. Means is provided for individually and removably mounting tumbling vessels on the carrier 28 at places located different distances radially from the axis of rotation of the vessel carrier and also centrally thereof. The vessel carrier 28 is shown provided with a multiplicity of apertures 39 arranged in circular series concentric with its axis of rotation and with an aperture 49 centrally thereof. The means for detachably securing the tumbling vessels 29 on the vessel carrier includes a plurality of holders 4i, each comprising a base 42 having an annular marginal flange 43 at the upper side thereof, this flange having an outer inwardly extending annular portion .4. Projecting from the rear face of the base 42 centrally thereof is a stud 45 adapted to engage any one of the apertures 39 and 49 in the vessel carrier,

and 46 is a nut to engage the outer end of the stud. The base 42 of the holder 4! is shown of dished formation with its concave side facing downwardly, this construction insuring a firm bearing of the base of the holder against the face of the vessel carrier 28, and when the nut 46 is tightened, this tends to flex the base 42 and draw inwardly the annular marginal flange 43 of the holder.

Each tumbling vessel 29 is provided on its lower closed end with an annular flange or collar 41, this flange or collar being conveniently formed as a separate part and secured as by welding to the bottom wall of the tumbling vessel. On the outer side of the annular flange or collar 41 is an elongated arcuate lock lug 48. The lug 49 is shown as circular in cross section and secured to the flange at its under side and ends by a metal bond 49. Supported on the annular collar or flange 47 for transverse movement in line with the lock lug 48 is a latch or lock bolt 50, the forward end portion of said latch or lock bolt, which has a beveled end face 5!, working in a slot 52 in the annular flange or collar 4'! and the latch or lock bolt being supported at its rear end by a guide plate 53, the latter having a slot 54 through which the rear end portion of the latch or look bolt extends.

The annular flange or collar 41 of the turnbling vessel is adapted to fit within the annular flange 43 of the holder 4| with the lock lug fitting against the underside of the outer inwardly extending annular flange portion 44 of the holder and with the slidable latch or lock bolt forced outwardly to bear against the inner side of the inwardly extendin annular portion 44 of the flange 43 0f the holder at a point substantially diametrically opposite said lock lug, the lower end of the annular flange 41 being forced downwardly against the base 42 of the holder H by the wedging action of the lug 48 and beveled face portion 5| of the latch engaging the inwardly inclined under face of the outer inwardly extending portion 44 of the flange 43, so that the tumbling vessel is firmly and securely fastened to the holder.

Operating means for the latch or look bolt 59 is provided that is operable from the outer end of the tumbling vessel and which provides for forcing the latch or look bolt 59, under spring tension, against the outer inwardly extending portion 44 of the flange 43 of the holder.

The operating means for the sliding latch or look bolt comprises a shaft 55 extending longitudinally along the outer side of the tumbling vessel mounted for rotation in bearing brackets 56 and 51 on the side wall of the tumbling vessel 29 at the upper and lower ends thereof, the lower bearing bracket 59 being shown open at one side and having apertures 58 in side portions thereof, the shaft 55 being retained in the bearing bracket 56 by a pin 59 engaging the apertures 58. On the lower end of the shaft 55, is a crank 60 to which is connected, at one end, a lever 6|, said lever extending through a guide slot 62 in the flange 41 and'having a laterally extending por tion63 at its other end provided with an aperture'64 through which extends the rear reduced end portion of the sliding latch or lock bolt 50. A cotter pin 65 engaging an aperture 68 in the rear portion of the latch or lock bolt 50 at the rear side of the laterally extending end portion 63 of the lever 6| serves as an abutment to limit the longitudinal movement of said lever in one direction relatively to the latch or look bolt 50. Interposed between the laterally extending end portion 63 of the lever 61 and a shoulder 6'! on the latch or lock bolt 58, is a coiled expansion spring 68. Fixedly secured on the upper end of the shaft 55 is a sleeve 69. the lower end of said sleeve rotatably fitting on the upper face of the upper bearing bracket 51. The sleeve 69 extends beyond the outer end of the tumbling vessel 29 and connected to the outer end of said sleeve is a hand lever that is adapted to be swung laterally for turning the shaft 55 to actuate the latch or lock bolt 50. When the hand lever 10 is in the position shown in full lines in Fig. 7, the lock or latch 50. is in its retracted position illustrated in Fig. 8 of the drawings. When the latch or look bolt 58 is in looking position, as shown in Fig. 6, the hand lever 10 is in the position shown in dotted lines in Fig. 7. When the latch or lock bolt 50 is in locking position, forced under tension of the expansion spring 68, the crank 80 is past the dead center point and thus serves as locking means to maintain the latch or look bolt 50 in locking position.

Each tumbling vessel 29 has a pair of cover attaching ears H projecting forwardly from the outer end thereof, said ears being arranged to cooperate with the hand lever 10 to lock the latter when the same has been swung to move the latch or;,lock bolt into locking position and in its retracted position. The hand lever 10 is connected at one end to the outer end of the sleeve 69 for limited movement in the longitudinal plane of the shaft 55 so that the hand lever 10, as it approaches the end of its stroke, can be raised to pass by the adjacent attaching ear H and positioned back of saidattaching ear H as shown in Fig. 7 of the drawings. The end portion 12 of the hand lever 10 is mounted in a slot 13 in the upper part of the sleeve -68 and pivotally connected thereto by a pin 14. Slidable in the upper part of the sleeve 69 is a plunger 15 that is pressed outwardly by a spring 16 interposed betweenv the inner end of the plunger 15 and the upper end of the shaft 55, said plunger having a head 11 at its outer end to bear against an inclined face portion 18 on the end portion 12 of the hand lever. As will be understood; the spring-pressed plunger 15 acts to yieldably maintain the hand lever 10 substantially parallel with the outer end of the tumbling vessel 29 so that, when the hand lever 18' is released and dropped back of the adjacent cover attaching ear 1 I, it will be held locked in this position.

I The tumbling vessels or containers 29, when interlocked with the holders 4| attached directly to the vessel carrier 23 as hereinbefore described, are disposed parallel with the axis of rotation of the vessel carrier. The means for detachably securing the tumbling vessels on the carrier includes means providing for mounting the tumbling vesselsso that the same will be disposed at an inclinationlto the axis of rotation of the carrier as well as parallel thereto. The means for this purpose comprises a plurality of adapter members in opposite legs thereof and secured thereto. On the base plate of the angle bracket, at the under side=thereof, are lugs 83, and the base plate has a threaded stud 84 fixedly secured thereto and,

projecting from the rear face thereof, said stud being adapted to be engaged with any of the apertures 39, 40 in the vessel carrier 28 and detachably secured thereto by a wing nut 85 on the stud.

The supporting plate 8| of each angle bracket is provided with an aperture 86 to receive the stud 45 of any one of the holders 4|, the base 42 of the holder fitting on the supporting plate 8| of the angle bracket and being detachably secured thereto by the nut 46. As will be understood, the base plate 80 of the angle bracket can be secured to the vessel carrier 28 in different positions of adjustment about its axis so that the angular position of each tumbling vessel relatively to the axis of rotation of thevessel carrier can be varied. Each of the tumbling vessels 29 is provided at its outer end with a removable cover 81, and with cover fastening means comprising the ears H and atransverse lock bar 88 rotatably engaging outwardly projecting elongated bearings 89 on the outer side of the cover 81, the end portions of the lock bar 88 being adapted to be engaged with slots 90 in the ears II. Fixed on the lock bar 88 is an eccentric 9| which is disposed between the bearings 89 and adapted to engage the outer face of the cover 81, the elongated bearings 89 allowing limited bodily outward and inward movement of the lock bar 88 therein. Secured on the eccentric 9| is a hand lever 92 for turning the lock bar 88. As will be understood, when the hand lever is swung to the position illustrated in Fig. 1 of the drawings, the cover 81 will be tightly clampedon the end of the tumbling vessel.
