. SPEcIFjIcATiON forming part ef Letters 3mm No. 760,590, dated iyia 24,1904. App lic ation filed September 20,1901. Serial No. 75,909. (Nomod'et) Rivers, in thecounty of Manitowocand State of Vvisc'onsin, haye inventedcertainnewand useful Improvements in Grading -Mach1n'es;

and I do hereby declare that the following is a full, clear,'and' exact'description thereof.

My invention has especialreference to ma chines 'forfgradingbean pods for canning fac+ .tories; and it cons'ists'iiicertain peculiarities of construction and .c'ornbinati'onofparts,as

willbe' fully set forth hereinafter inconnec tion with the accompanying drawings and subsequently'claimed. In the said drawings, Figure 1 is a longitudinal sectional View of a machineembody ing'm'y presentinvention, taken on the line 1 l of Fig. 2. Fig. 2 is a plan Viewof the said machine, portions beingshown broken,

away'in both figuresto-better illustrate cer-' taindetails of construction," Fig. 31 is a trans planes indicated by theline 3 3 in Fig. 1 and drawn to an enlarged scale. 'Fig. 4 is'adetail Referring to the drawings, a a b b c cre r ssent the uprights of successively decreasing height, and d d the inclined side pieces of frame, the said uprights rising-from anysuit gether to form a rigid support, the base and braces being of any ordinary constructionand not herein shown. Secured to the said uprights are o'ifset extensions, (markedlee', ff,

and 'g g, respectively") and to the upper or outer ends of these extensions there farepiv otally secured the upper ends of hangers h h, whose lower ends are pivfotally secured to theshaking' screen, next to be described. This shaking-screen comprises, priin'ar'ilyjtwo in -f clined side boards i i, connec r at intervals by thetransverse boards fly",

.flatly againstthe undersides o he'boards and hence being similarly inclined, and resting on these transverse boards' j jare transverse beams is k, and inclined uprightboards m m are securedto the side boards 11 ion the e'beinglaid inner sides thereof and similarly-restingon 5 the boards j, j between the ends of the trans'-' Versebeams '70 and the said' side boards '73 i,

-the attachment of'theboards 7' to the side boards 71 and of the latter to the boa'rdsm being plainly shown in' the detailyiew,Fig.-

Thesebeams' k 70' are slightly inclinedin .opposite directions on both their upper and lower' surfaces with vertical'sides, "as best shown in Fig. 1, andtransverseuprightboards n n are secured toth'e sides of these beams'k 60 Is nearest to the'upper or higher end of the machine, whilesecured, as by bolts, to the'upin regulardescendingseries, as best shownin "Fig; 1., These screen-sticks are arranged with each two adjacent sticks on a beam Jig-being separated by spacing-blocks 9-; also bolted'to- 7'6 r the upper faces of the said beams; and inthe Verse vertical sectional View taken on the illustration here. given the said beams, with" their sci'een-stickaare arranged in group'sof three beams each, although thefemaybeas imany of saidbeams in a group asdesir'difi '7'5 any'given 11istance, and the shaklng-screen may contain as many groupsga's thought 'neces "sary,' 'three onlyof such groups beingshewn' "1n the present drawings,- andbeneath'ea'ch group an open four-faced hopper qissecured to the inclined outer side boards" 0? d of the 10 pin-each successivegroup'are of different 5 and increasing width, the narrowest blocks, 32''," 1

being? betweenjtlie sticks 0, securedto the upper group-(bf three beams in thisinstanceQ k ewhatwiderblocks, p, are employed between the'sticks 0' 'of "the next "group and 9 still' wider blocks between the sticks of "the next lower group. andso on,if more'than" three groups areemployed.

At intervalscorresponding to the 'lohation of the upright extensions'e fg, &c.,;the side boards 'zi fd f'of the shaking-screen areprovided with blocks r 1' on their under sides, to'which are pivotally secured the lower ends of the hangers h h, and at the upper or higher end of the machine the lower ends of the adjacent upper pair of hangers h h are connected by a transverse rods, which extends entirely across the machine and through both of the upper pair of blocks, while the lower ends of the other hangers are merely pivotally connected to the blocks on opposite sides, as best shown in Fig. 3. A transverse crank-shaft tis jour-' naled in suitable bearings u u, secured to the uprights a a at the head end of the machine, and a link 41 connects the cranked portion of the said crank-shaft with the described front transverse rod 8, the said crank-shaft having a pulley w at one end, whereby power is transmitted to the same. The tail end of the shakerscreen is provided with a suitable shoe, the simplest form of which is a transverse board 00, extendingacross from one side board c to the other, and with two converging upright boards 9 z, arranged to extend from-said side boards toward the center of said board 00.

' The operation of my machine will be readily understood from the foregoing description of itsconstruction, taken in connection with the accompanying drawings, which clearly show the preferred shape of the screen-sticks 0 0, the'same beyond their squared attaching ends being substantially lozenge-shaped in crosssection, with narrow flattened longitudinal surfaces at the top, bottom, and each side at the intersection of the widest faces thereof, this form having been found to give the best results in practice. The bean-pods containing the green-beans are strung and canned in that way; but it is very desirable that the pods should be graded as to size, and to that end all the pods are dumped on the upper group of beams and screen-sticks (suitable receptacles being placed beneath the hoppers Q q) and power imparted to the pulley to, which causes the entire screen to be reciprocatively shaken, and the smaller pods will fall through between the sticks 0 of the said upper group into the hopper and receptacle beneath, those of larger size being shaken over onto the beams and sticks of the next group, and so on,-to the tail end of the machine, where any that fail to fall through between the sticks 0 0 of the lowermost group will be discharged from the shoe :2: y 2 into a proper receptacle,

to be again passed through the machine for,

grading, if desired. Thus all of the pools are properly graded preparatory to being canned. The transverse upright boards n n prevent the pods from being shaken toward the head end of the machine into the wrong hoppers.

My machine is very simple and economical in construction and extremely efficient in use, and while I have illustrated the preferred construction it will be understood that I do not limit myself to the precise mechanical details shown, as same may be varied within the scope of what is herein claimed without departure from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

8. In a grading-machine, the combination with a stationary frame, of an inclined shaking-screen suspended therefrom, comprising transversely-arranged beams havinginclined tops, a seriesof spacedsticks secured at their forward ends upon said inclined tops of the beams, their rearward ends being free and extending abovethe next lower beam and overlapping the secured forward ends of the adj acent series, and a stationary hopper arranged beneath said screen and common to each of the series of sticks.
