Application filed November `5, 192). Serial Noyfllfl-l.
To all lwhom t may concern Be it known that Max ELLRIGH, citizen of the German Republic, residing at 173 New York Avenue, Jersey City, in the county of Hudson and State of New Jersey, has invented ce-rtain new and `useful lmprovements in Conveyers, Aof which the folylowing' is a specification. l
The present invention relates to conveyers for conveying tubularl containers, particularly such which are used to convey tubes containing cork composition for treatment in an oven. y
My invention has for its object to provide means which will automatically and securely grip or connect the tubes to the conveyer and automatically release the same'` after they pass out from the oven or apparatus in which they are treated.
With the? object in view my invention con sists in the novel construction, arrangement, and combination of parts as will be hereinafter more fully described and defined in the appended claims.`
In the accompanying drawings in which similar reference characters denote correspondingparts, Fig. l isa top plan view of one end and of one side of a tube conveyer; Fig. 2 is a vertical sectionon line 2,-2 of Fig. 1; Fig. 3 isa section on line 3 3 of Fig. 2; Fig. et is a more or less diagrammatic view of one end of theconveyer; Fig. 5is an elevation of a detail, and Fig; 6 isa section on line 6-6 of Fig. 1.
Referring specifically to the drawing 10 denotes oneof the sprocket wheels arranged on shaft 11 and over which run two parallel endless chains 12, of which only one is shown in the drawing. These chains are adapted to be connected together by frames 13 for supporting the tubes 15 containing the material to be treated in an oven, while conveyed through the latter. Each chain consists of rollers a, mounted on pins Z) and lconnected by end links c and d. The frames 13 are each composed of a pair of parallel bars 13, 13. extending transversely and adapted to be fastenedto the opposite in` ner links l of the two chains.
The two parallel' bars 13', 113 are in height and spaced apart a distance substantially equal to the diameter of the tubes, and in length equal to the distance `between the opposite links of the two chains. The attachment of said bars 13', 13 to the links cl, may be accomplished in various ways, Y
butl prefer to use the following construc-` Onthe innervextensions of thepinsbof the two adjoining rollers a are mounted ver-` tically disposed recessed plates 16,. which.-v
`havelateral projections 16 yadaptedto vr'be passed. through holes made iny the ends of `the bars `13" andtobe suitably fixed thereto in position. vThe platesy 16 maybe steadied lin position on the pins b by cotter` pins-18 or the like. Each pair of bars 13, 13 form between themselves al pocketl ldapted o t i f receive a tube 15; -The tubesl arehsomefI -what Ashorter than the pockets 14,' so, that i when positioned therein there is a free space formed at eachend Jfor the-accommodationof `a gripping member.. The two gripping members and .their arrangement 1n each pocket are identicahand I shall, therefore@ describe the construction of the conveyor at the oppositeiside is tubes are open at their ends and are packed i with 'the'material'to be treatednotquite to f the ends, leaving free lspaces suiificientlyV large to receive` they extreme ends of the' gripping bolts .19 which when'movedginto operative position willfengage the tubes.; f
At points near the open'ends of the tubes."
\ vhen properly. positionedin the pockets 14, l provide `guide membersin form 0fapair of parallel plates 20'l arrangedin vertical positionv and provided with central circular holes 20 in which the bolt-'19 is movably supported. These guide members `2O are fixed in the bars 13 13 similar to the plates 16. The outer end of this locking bolt-19 is centrally slottedin longitudinal direction as at 19. to movably engage a horizontally 1- disposed bridge plate 271, which again "is fixedr to the bars13, 13 in like manner as plates 16.' This plate 21 isvr providedwith a longitudinal central recess 21" hav-ing at its inner end an enlargement 212. The bolt 19 is rectilinearly guided on ysaid l`plate-21 by a guide pin 22 which passes ,through'the slot or recess .21. Borne in the boltll9 is a. vertically movable lock pin 23` ofgwhich the upper part24- is enlarged in diameter,
and which extends through the slot 21.
The, enlarged portion 2-1- of said 'spin projects outwardly or upwardly throughl a correspondinglyenlarged bore 192 of the bolt.
rlhefree end of the reduced portion of the pin 23 is formed with` a head piece 25, and agsprinn 26 is mounted around said reduced part of the pin to rest with one end against said headpiece and with its opposite end against the outer face of the bolt 19, the same having the tendency toI draw the loclrl pin 23. downwardly. w"Ji/hen the bolt 19 isinl inoperativeposition the enlarged l, end 24; of the lock pin will be displacedrela- `tain guide pieces and cams rare providedr -for guiding thechains and the tubes and tive to the enlarged part 212 ofthe slot and the` pin,v therefore, held in unlocked posi- -tion permitting the bolt to be moved. l`When 4the, bolt 19 is moved inwardly or into locking' position, the part 2e ofthe locking pin comes into thejrange of the jopening 212 and snaps into it by force of' itsspring-26 and thereby locks the bolt in operative position. 5
"Extending from the` inner circumference .ofthe sprocket wheels 10 inthe direction of travelof the chains and below the latter is astationary bed lor base 17 `onwhich cerpairof guide memberk20'is a rail27. These ymembers 20 are vsomewhat extended ver- `tically' totengjagethe sides of said rail 27 whenthe conveyor *passesr over the table 17v so as to insureA the proper positioning ber relative to the vcams lwhereby the latter lare :adapted to be automatically operated.
There is acam 28 fixed' on the table 17 to extend in the path ofthe lower end 25 of the locking pin for releasing said pin from its 'locking position.l This cam 28 is in form yof a bar extending longitudinally of the chains andhas an incline 28. Fiiied in the bolt 19 is a vertical pin'29 which projects downwardly towards the ta-ble'and rlockingpin 23 and the consequent release of the enlarged part 24C thereof from the opening' 212 of the slot 21 this cam surface 30 vwill engage the pin 23 and, as the conveyer proceeds in its travel,` cause the bolt 19 to move outwardly withdrawing its end from the tube 15, while the other cam surface 30 subsequently again engages the pin 29 and moves the bolt positively back into gripping position. There are also bars 32 iixed on thev bed 17 adapted to extend longitudinally thereof below the tubes ,15 to sup-l port the same ywhile the conveyer passes over the bed. Thel latterat a place below the discharge end of the chutes is recessed as at 17 to permit the tubes 15 afterv their unlocking to fallinto a receptacle (not shown) below the bed. p d
The mode of` `operation isjas follows:v
As the conveyer is 4delivered fromf the sprocket onto the`bed 17 the tubes Y15 pass onto the supports 32, the roller-sa ofthe chains', onto the rails 26 and the guide bar 27 engages the guide member ,20. 'At the Sametime the'lockingpins23 at both sides are engaged by the inclined 28" of the bars28 and are lifted releasing the upper ends24 of the latter from 'the' openings 212 ofthebridgevplates 21. As thejconveyer continues to travel over the bed with the pins 23 unfloclred, the pins 29.` encounter the blocks 30 andk bythe cam surfaces ofthe-,latter are caused to move the bolts 19 laterally releasing them from the tubes `15, which thus become unlocked one by one and fall through the recess 17 Vof the bed. l f
The emptied. pockets 14, as the conveyer proceeds are being `filled by fresh tubes 15 fed from the chute S and thesetubes on enteringthe pockets are gripped by the bolts 19 automaticallythrough the, operation of the blocks 81, whose cam Vsurface 31 now engage the pins 29 and/,positively move the bolts 19 into operative position. It is obvious that the device may be variously modiiied without departing from the principle of my invention, an'dI', therefore. ,do'not wish to restrict myself to the details "shownand described. l f y I s i t1 u n y o t e operative par s o ne grippinginem- What l claim iszi 1.'In' a conveyer.y ofv the character d'escribed, the coinbinationfwith tubular coiitainers open at their ends, of laterally movable members adaptedto enter theopen ends of said containersto retain them in position.
