`Et-referring particularly to the showing of Figure 3, it will .be noted that each pocket jointly "provided bythe cup member 35 and the corresponding scoop extension 38 is arranged for-movement upwardly through the articles N in the lower `portion ofjthehopper "I3ito ipick up and 4gravita-ily Vretain a .single article N for yits -movemerit -to the 'top of the drum lfl 2`ior imprinting 'thereat an'd'its subsequent falling f-romthe'socket into-a receiving vtray for 'chute 51 at-'theoppos'ite 'side 'of the carrier drum 'from-the pickup point, said lpockets 'rst engaging the 4articles N in the hopper `at a point 'somewhat 'below-the tlevel of v'the'carrier' drum axis; The hopper fbottomadjacent lthe zone of action of thelpocketslisgpreferably formed to "so position the 'articles iN that they fmay be picked up 4singly 1w'itha minimum ydisplacement 'of the Iadjacent larticles.

" veffective pressure and resistance of the 'later.1ar ticles is primarily downward rather than toward the `drum I2. With this arrangement, .the danger ofcrushing the 'articles vin the hopperand a 'lled `and the scoops and the pocketed articles with the vreelarticles .in the .hopperftends to rotate thepocketed and v.free articles in a .direction op- .posite .that of the drum.; vthis action reduces .theeffectve resistance of theree" articles to the rotation of the drum, while preventing .a `destruc- In the case of more or less globatearticles havinga radial projection or a stem, the described fri-ctionally induced rotation of each pocketed ar-` ticle is moreor less stopped -when the projectionY thereof strikes the socket step ,40 forwardly of the scoop bottom; in thismanner,` the projection .may be disposedv away from `.the zone of `ac- `tion of the stamp 1I5 whichlis to'print `on the article when the latter has been moved'upwardly to the printing point.` This positioning action of the Steep 40 is particularly 'valuable with respect to walnuts or other,` articles having equatorial ridges n, it being notedthat the described 'frictional engagement of a pocketed walnut with free walnuts in the hopper will almost invariably` dispose the ridge 'n of the walnut flat against the pocket step 4D and so provide for abranding of the pocketed nuts at corresponding convex surface portions lacking the ridge n.
In the present machine, ink is supplied to the inking roller `H5 from a pick-up roller 6|,Iwhi'ch comprises a longitudinal side of an ink troughor which is arranged for alternate engagement with the roller 6I and a roller 64.` The roller 64 con- I stantly bears against a roller 65 which in turn constantly bears againstlthe inking roller I6,'the ` rollers 64 and 65 and I61being engaged along axial `lines of their faces with adjustable degrees ifof pressure in a train whichlis` designed to provide an even coating ofink upon the roller I6. Aslthe printing cylinder `I4 revolves, it is arranged to successively present` the faces ofthe branding stamps I5 against the roller I6 for receiving a printing charge of ink therefrom.
Preferably, and as shown,`the train of rollers 64 and65 `and I6 is positively driven, with A,the latter 'roller having `substantially `the same peripheral speed as the printing cylinder whereby a constant and uniform supply of ink for the stamps is assured-` In Athe present instance,` the dri- ving ofthe rollers 64 and 65`and I6 is effected by driving the roller 65 from a shaft 66 mounted on the `frame II generally below `the trough 6|.
` `As shown, the shaft 66 mounts 1a gear 61 near one end thereof and operative throughidler gears `68 and 69 to actuate a gear 1I.` mounted at an end of the shaft carrying the roller' 65. The. ap-
connection with this seating of` a walnut ina cup 35 during its brandingJt is to beV noted thatas a pocketed walnut is raised beyond the walnuts in the hopper,` it rocks or rolls in thecup 35 until its flange n is no longer opposite the 4pocketstep 48 when the'seating and printing pressure is applied; in thismanner, the desirable fitted pressing `of the positioned walnut into Athe yielding rinaterialof thecup isperrnitted'.
When the stamps have been appropriately set in the cylinder,` their pressureengagement with the inking roller I6 for their inking may need adjustment;` in the present instancefthe shaft I9 of the inking roller I6 is carried on and between I support forks which are horizontally and inl dependently adjustable on the machine frame II to provide any adjustment needed. Following any positioning adjustment ofthe inking roller,
the pressureengagernents `of the roll`e1164 with the roller `Il and of the roller` 64 with` the `roller 65 may be adjusted as needed. ,I
Theshaft 66 also mountsa pair of l generally elliptical plate cams 16 and 11, said cams being that the rotary action of the cam will alternately engageI the `transfer roller 63 with the `rollers 6I and 64; the arm 8I-ispreferably arranged for its constant engagement against the peripheral working edge of the cam under the influence `of a spring 82 which constantlyl urges an appropriate turning of the rock-shaft. In this manner, a constant rotation of the shaft 66 is arl `ranged to periodically effect a transfer of ink from the roller 6I to'the roller 64. v
propriate driving of the inking roller I6 is eiiected l by means of a belt 12 connecting pulleys 13and.
14 respectively mounted on extending ends of the shaft I1 of the carrierldrumand the shaft It will now be noted that, for best branding results, the articles N tobe printed on must be of substantially the same size; in the case ofi nuts and other natural or artificial articles `which may vary in size, those placed in the hopper would be of a gradedrsize range `whereby the branding stamps I5 maybe set foruse with the averagesized articles of the lot. In setting up the `present .machine for branding articles N of a given layerage size, some of thearticles are run through the 'machine and the positioning of the individual branding `stamps I5adjusted radially by adjusting the sleeve nuts 53 until all the stamps on the' vprinting cylinder have their printing faces. disposed in a common cylinder ofxrevolution jex` cept while they are engagingl an article :being printed, the radius of said cylinder of `revolution being such as to provide a `printing Spressure of the stamps on theengagedarticles which will so press` the engaged articles into the :yielding cup bottoms as to secure themagainst rota tionlor shifting `during thebranding thereof.` In `'I5 The cam 11 is peripherally engaged by the free end portion of an arm 83 which is pivoted on the shaft 84 of the pick-up roller 6 I beyond oneend ofthe ink trough 62, anda spring 85 is constantly operative between the arm 83 and an anchorage on thefmachine frame for constantly engaging the arm 83 with the peripheral edge of the cam` 11.` The rocking of the-,arm 83betweenlirniting, positions determined by thefeccentricity of the `cam is` arranged to `effect a rotary displacement `of the roller 6I during each cycle of operations of the cam through the action of a pawlll86 mountedV on the arm.83 and operative against l the teeth of As particularly shown, the arm `83 is formed to provide for the pivotalmounting of the pawl 86 thereon for swinging about an `axisabove and generally" parallel tothe axis `of the roller l 6I, and the pawl 86 is `arranged to` so operate against the ratchet gear 81 thatfthe portion of' the roller a ratchet gear 81 fixed on the shaft Vperiphery which acts asthe front reservoir wall is moved downwardly` each time the roller is rotatively shifted through themovements of the larm 83; in the present instance, the pawl`86 is of the hook or drag type, is arranged to gravitally bear against` the `toothed periphery of the ratchet gear 81, and has its working `point operatively engageable between adjacent `teeth of the gear 85 only when moving upwardly, With the present arrangement, the pawl 81 `is operative to effect -:airotaryshift of the -rollerl while the 1arm1'83 "is movingi'towardfthe shaft E65.
