HT TOE/viv bers D, is a cross-angle 29. Also fixed to, and rigidly at the rear upper corners of the member D connecting, said end-plates 26, is a channel-member having its flanges presented rearwardly, as best seen in Figure l, and riveted or otherwise iixed to and upon the channel 30, is a skirt shaped plate 31 langedat its opposite side margins, as at 32, and providing a'diseharge-chute, which is normally, as when the carriage B is in fully lowered position, presented upwardly relativelyto the iramoworx A, as shown in full lines-in the drawings.`

Riveted or otherwise fixed to said endplate lower flanges 28 and rigidlyart the lower rear corners of member D connecting said end-plates 2G, is an angle 33, and re-'ini'oroing the member D, is a strut 34 and diagonal braces 35, suitably fixed to said rear vupper channel 30 and rear lower angle 33., as best seen-in Figure l, v

Y rlhe member D `is thus openboth at'its front and lower sides to readily receive a dough-containing trough E, illustrated in dot-and-dash lines in the drawings, which trough, when the member D is in lowered orrnormal position, is conveniently rolled into the member D' at its open front side to rest upon the bottom. or lower flanges 28 thereof, which flanges, during movement oi the elevator B longitudinally ot the iframework. A, provide supporting or carrying members for the inserted trough E( VFixed lcrosswise upon the depending an- 10 and at each end of the carriage are spaced pairsot angles 36, which provide or torni crossltraclrways "for rollers 37 mounted y 'for rotation on stub-shafts 38 suitably iixed,

f as at 39,*rigidly upon and laterally proj ecting I n voutwardly irom the' endplates 26 or the member D. By means thus of the stub-shafts 38 and their roller-bearing connection with i the trackways 36, the member D not Vonly is movable with the elevator B longitudinally ot' the frame A, but'also is pivotally swing able ortiltable relatively to the elevator 'B and irame A during movement oit the elevater D longitudinally ott-he traine. At they sai mtime, it ywill be noted, the rollers 37 are adapted `to travel in the trackways 36 crosswise of the frame end-members to freely ei'- itecta shitting ot' the supporting-pivots 33v oi' the member Dupon the elevator D and thereby maintain a constant radius during swingable actuation'of memberrD about its lswiiigable or tiltable center, shortly to be de scribed, as the member D is moved longitudij 'nally of the trame A with-the elevator B.

Riveted or otherwise iixed to and at the lower end of the frame-uprights l at the l front oit the machine, are relatively short angles 40 extending ij'or part of their length longitudinally ot and with the uprights l and then arcuat-ely bent, as at 41, to project ob liquely outwardly and upwardly, as at 42,

Leseo? relatively to the iframe-work A, the angles 40 providing trac-kwaystor rollersf43car i ried for rotation upon angle-brackets 44 fixed to and upon the lower angles 28` of y endplates 26 of the member D.

Rivetod or otherwise rigidly fixed upon thebers, are rearwardly presented plates 45 rigidly supporting adjacent their-upperends oppositely disposed inwardlyfpreseiited.studs or stub-shafts 46, adapted for pivotal engagement with which studsor shafts 46^in theH operation 'of the l machine, :tor q purposes shortly appearing, are Ueshaped members 47 forming part of brackets 48'rivet`ed or otherwise fixed to upwardly presented flanged endextensions 49 ofthe memberD, said exten- V i sions 49. being riveted orotherwise rigidly iixed to the end-plates 26 aiidchannel 30 of member D and said U-shaped brackets 48 being normally .presented f upwardly, .as 'y shown. Fixed upon the inner `faces ot the plates 45, are suitably spaced angles 50 which provide retaining guide-ways for the braclrets 48 in the actuations of the dumping-mem@V bei' D, now to be. described.

ln use and operation and assuming first that the elevator B and its carried trough dumping-member D are in normal or fully lowered position, as illustrated in full lines in Figure l, a trough E is rolledv lintothe member D to rest upon its lower ifiangesl 28.I The left-,hand cord 19reterence being had to Figure 2, is now pulled`r toeect elevating actuation ci Y the hoisting mechanism, C, whereupontlie elevator B is causedto ascend or travel upwardly within yand upon the trame-work A, throughoutfthe travel of the io; y

elevator Bfitsv rollers l3jsmoothly working in the traclzways l2.` .As thelelevator B isso caused to travel upwardly in the frame "A, the dumping-member Dv and its .carried trough E first travel upwardly inra straight path in and relatively to lthe traine ,4, until the Vroller-S43 approximately lreach the aic'u-` ated bend .4l in .the traclways 40, at vwhich time the parts are'so relatively proportioned that, the U-'shaped brackets 48 have reached and liiivotallyengage with the ixed studs 46.Y

O'n now continuedjupward travel ot the carriage B, the dumping-member D', being en` x gaged, asV described, at its'braclrets48 with theiixed studs 46, will be pivotallyswung or tilted, with the fixed studs 46 asa center, through an arc of approximately130o, so

that, when theelevator'B has reachedthe limit of its upward-travel as determinedby y engagement of the' bracket 25 with the upper block 24, the dumping-member D will oclcupy the fully swung or tilted position thereizo of illustrated in'dotfand-dash linesinlFigure f' 2, in which position 'of the vdu'inpingiii'e'mber D, its contained trough E will besimilarly iso tilted, so that the contents thereofmay freely discharge through the chute 31 into the adjacent dough-miXer'F; e y y The contents of the carried trough E having been discliargedintothe'miXerF, the

other oi` right-hand cord 1-9, reference being Y again. had to Figure 2, is actuated to effect f descending actuation of the hoisting mech i anism C, whereupon theqcarriage B andV its carried parts are caused to travel down` wardly within and relatively to the frame A, during which descending Vmovement the dumping-member D is, in like manner, reversely tilted to assume, when the elevator B has reached the limit of its downward travel, as determined by engagement of the bracket v with the lower block 24, full initial or normal position. e Y I lVe might here state that, in the upward travel of the member D vwith the carriage B', the initial swingable movement ot the dumping member D is freely permitted by the obliqiiely outwardly and upwardly disposedA to the carriage B and the frame-Work A throughout such Vpivotal or swinging movement thereof, that the rollers-37 freely permit, as stated,a shitting of the supporting pivots ot the.dumping-members D throughout such swingable'movement thereof,` and that the upper cross-member Q9 ot member D securely retains the trougli'E within the mein-.

ber D when the same is in full tilted or discharge position. f Y n Vile are aware that changes in the torni, con-y struction, arrangement, and'cembination of the several parts oi ournew machine may be made and substituted 'for those hereinpshown and described without Vdeparting fromY the nature and principleotl our invention;
