. Twist-Belt Conveyers for. Newspapers and the like,

' ficationof which the following is a speci- This invention relates to belt conveyers for newspapers and the like and more es 'pecially to novel conveyersof this general description in which during the translation of articles, by a part of said conveyer, up-

wardly or downwardly as the case maybe,

there is also imparted to said articles a rotary motion about a more or less vertical ,line of travel, to the end that said articles I maybe laterally delivered from the elevator whether traveling up or down in a line extending, for example, at an angle of 90 to 1 the line in which they were introduced into saidel'evator; said lines beingof course not only in different horlzontal planes or levels but also in different vertical planes, .preferably planes intersecting along and corresponding to the axis of rotation about which said articles are turned duringtheir conveyance between the different levels. j

To provide means therefore whereby articles may'thus be angularly turned duringtheir translation along a given path and to effect this angular motion of said articles Without injury to said articles are among the principal objects of the present invention. f X

Another object of my invention is to so constitute the respective elements of the preferred embodiment thereof ,as

certain of said elements for ready adjustment with respect to eachother to adapt them for expeditious assembly.

These and other obiects of said invention will be hereinafter referred to and the novel I to avoid the t provision of a multiplicity of differently. formed bearings and the like, while fittingv principles of my invention.

V Y r ig. 6 is a side view of a fragment of my novel-twist-belt, showing the same inposi-- tion on a roller a portion of which has been broken away for purposes of illustration. Fig 7 "is a fragmentary detail section of said belt,'the section being taken on'line VII-VII of Fig. 6; and i Fig. 8 is a bottom view of a the belt shown'in Fig. 6. p I

The construction given byway of'exernplification' comprises a horizontal; run ,of beltingcomposed' of narrow belts lywhich pass around pulleys 2 and 3 at the'respective ends thereof. The shafts'l and 51uponwhi h fragmentof these pulleys are mounted arev driven in synchrcnism by means of chain and sprocket connections; theshaft 4 preferably" driving Fig. 1, Ihave indicated such chain and Y sprocket drives as this, wherever they occur;

by dash and dotted lines. 7 Thus, the sprockets mounted upon the shaft 5. by' means of.

nated 6 and the chains corresponding thereto 7: while the drivin sprocket on the shaft 4 l e been desi nated 8.'

The horizontal belts 1 are supported be-" 'ncath their carrying surfaces by rollers 9 which this shaft is driven, havebeen desig and the p pers ar d iver t the lt by'a ".-fly lO such as is providednn connection with many printing-presses 1n common use.

are delivered from the belts 1 to what. are known as angle belts 11, which may be arranged with respect to the belts 1 as indicated in Fig. 2.

fIlfmake no claim herein to these angle belts, which may hence be of any suitable character but which are preferably mounted on pulleys 12, .13 and 14, asshown in Figs. land 2. The pulleys 14 are mounted upona shaft 15 carried by pivoted arms'l6 to the end that said pulleys 14 may tension the V angle belts. The arms 16 may be pivotedas at 1 7 to brackets 18 attached. to the uprights 19, which as shown in. Fig. 2 may be channeled.

Theuprightsor channels 19preferably do not' extend all enemy from the bottom to the top of the elevator; but preferably have I attached to their upper extremities a subdistance below this band is a second and ,similarband 21 whlch s shown. 1n plan .111 Fig.2,

stantiallycircular band 20, while a short "A." second set of upright channels 22 eX- tends up from the lower band 21 and .is securedto this latterand to the ,band 20; but it willbe observed that the channels 22 are angularly spaced around upon their :supporting bands, each at some distance from the corresponding lower upright 19.

vIn this convenient fashion, Iwhat I may term a twist-frame is provided, in which the relative lengths of the respective upper and lower uprights in view of the total amount of twist in the conveyer, will determine the angular displacement of the uprights 22 fwith respect to those designated 19. In the present case, the total twist is approximately 45. p Theuprights22 may be connected at their upper extremities by a cross-bar or channel- 23,"as shown in Figs. 1 and 3; a portion of channel 23 being broken away in the latter figureto better show the belt connections. Laterally projecting toward one side or another of the respective uprights l9 and 22,

arcuate bearing plates 24 are provided at any desired different levels, to carry the bearing brackets 25 in which are received the journals 26 in which ride the trunnions ior'shafts 27 of the respective guide rolls 28.

The plates 24 are spaced inwardly from the upright channeland aresecurely at- .tachedto the latter by bracket-plates 29, as

shown in Fig. 2; and the provision of these arcuate plates as a means of support for the roll bearings is'of particular advanta e in that it greatly facilitates the erection of the elevator; the frameof the latter assembled and the arcuate plates attached The papers in overlapped relationshipwith grooves 28,1which,as shown in Fig. 7

upon said plates 24. The shafts 27 are thus supported in different vertical. planes at their different levels, and then the rolls and their bearings and brackets are adjusted angularly with respect to each other, as best erly lined up. The brackets 25 may thenfbe ,securedin placeby means of bolts 29 or the "like; one bolt suflicing for each bearing bracket. .As shown in Fig. 5, each ofthese brackets are preferably provided witha de pending flange 25 .upon their inner side, through which the corresponding bolt 29 may be passed; while this flange isturned laterally and then downwardly to aii'ord a recess for the upper edge of the plate 2% to which it is attached, so that this edge is, in effect, embraced by the bracket to a secure connection therewith.

The journals 26'are provided with laterally extending lugs 26 which are received into vsshaped cuts or recesses in thesides of the brackets; this arrangement permitting of a'rocking movement of each journal withrespect to its bracket, since the aperture in the bracket which receives the journal is of,

somewhat larger diameter to afford an annular space therebetween. As a result of this, the rolls may be [canted or 'slewed around with respect to their supporting journal brackets, through a considerable angle; theuppermost roll28, Fig. 2, for instance, is sho'w-n thus disposed with respect to one of its brackets 25, in said figure.

Each of the guide rolls 28 is provided preferably flare outwardly, so thatin cross section theyare substantially trapezoidal, to

favor the reception thereinto of spaced guiding projections or lugs uponthe belts which ride thereover.

These belts, which are the main elevating belts, have been designated 30 or 30, as the case maybe, and may be of leather or the like and preferably have secured to their pulley-contacting surfaces, guide-projections 31, which as shown in Fig. 6, may be conveniently made by riveting together and to the belt 30 or 30 to which they are attached,

for example, two thicknesses of leather belting cut. in blocks, so that when assembled thereto, after which the various bearing j V brackets 25 withtheir journals 26 and rolls 28 are mounted approximately in position shown in Fig. 2, until they have been proptford a byl m eans' of this construction," the belt retainssubstantially all of its flexibility and may readily be passed around pulleys of, for example, six inches in diameter, while byreason of these projections and of the grooves in the pulleys, the belts where engaged with the pulleys, are at all times definitely positioned thereon. A further and more important" advantage resulting from this provision will be hereinafter discussed.-

The belts 3030 are preferably arranged in sets; there being in the present case three belts in each set. I

. The respective sets'of belts move in the direction of the arrows indicated adjacent thereto and since the construction given by way of exemplification is intended to elevate the newspapers from one level 'to another,

the opposed sides of the respective belts" 3030 'move upwardly together, preferably slightly, zig-zag between the pulleys 28,

- with their fronts or projection-free faces in a angular pulleys 36,

contact with the papers against which said faces are passed. The guide and pressure rolls 28 are preferably arranged in staggered relationship from top to bottom ofthe elevator and as the article-conveying portions of the belts 30-30 "pass up between these staggered rolls, said belts will also be rotated or twisted angularly, owing to the shift of thexaxis of eachroll with respect to the axis of'the roll immediately therebelow.

The article-carrying run of each of the belts 30 passes around a pulley 32, of which of course there are three, mounted on a shaft, 33. Thereafter the three belts 30 run downwardly toward and pass around thecorresponding pulleys 34 mounted on the shaft 35 at vthe lower end of the elevator. Correspondingly, the belts 30, when'they reach the limit of their upward travel, pass around mounted on a shaft 37,- adjacent the cross-bar 23; and said belts thereafter descend, as indicated in'Fig. 1, toward and around the pulleys 38, mount ed on the shaft 5. above;referred to. The descending limbs of the'belts 3030 are heldagainst lateral vibration by guide or idler pulleys 39, mounted upon brackets 40, which as shown that after;- a given pulleyfbearing 40 has once been positioned with respect to its corresponding bracket-base 40',it is made fast in any su table fashion to prevent the tension of the belt rotating it inadvertently ab t its pivotal axis 41. Belt tig teners are also provided for the respective belts 3030". these tighteners each comprising a pair of shafts 42, the ends of bearings 55 attached to the upper ties of substantially while the which are mounted in" rocker frames 43,

which are pivotallyattached to cross-bars 44 as at 45. These frames 43 are each provided with a spring 46 which tends to rock faced pulleys or idlers 47, while the corresponding upper shaft carries grooved pulleys 48; the outer or smooth side of the belts engaging the pulleys 47 and the projections 31. riding in the groovesof the pulleys 48.

At the top of the elevator are two angle belts 49 which pass around pulleys 50 mounted on the shaft 37 pulleys'51 mounted on a shaft 52, and pulleys 53 mounted on ashaft 54. i

Shaft 54 is journaled at its extremities in extremi- V upright links 56. These latter have bolt and slot connections 57 with the frame of the run-out section of the apparatus, so as to permit of definite adjustment vertically of said shaft 54 with respect to this section and more especially to permit the paper-engaging sides of these belts to be bent down slightly around the pulleys 58, of whichthere'are two as shown in Fig. 3, and" over which pulleys pass the underneath or coacting angle-belts 59, which receive the papersqfrom the belts I The upper ends of the links 56 are con- 'nected by the ends of the shaft 54 to the outer ends of links 60, the inner ends of nels 22.

The shaft 52 is journaled in the respective free ends of arms 63,*which as shown in -which are pivoted at 61 to plates 62 which are attached to the upper endsiof the Chen- Fig. 1 are pivotally attached at their lower ends to plates 64 by means of a shaft 65.

The two belts 59 above referred'to, each pass around but two pulleys, one of these being designated 58 as above noted and the other being the corresponding pulley. 66. The pulleys ulleys 66 are mounted on the 58 are mounted on shafts 67" shaft 33 w ich carries the pulleys 32 above referred to.

On this shaft 67 arealso three pulleys 68 around which pass the respective horizontal delivery belts 69, the upper or papercarrying' sides of which. are supported on one or more rolls 7 07 0', as shown in Fig.

1, while'the under sides of said belts rest on idler rolls 71.

The rolls 70 and 71 arejournaled in suit able brackets carried by the horizontal mem-' bers 71 which extend .to the point where the papers are to be delivered from the endless V belts 69. in a known manner. I

The shaft 5 is'driven clockwise, as viewed said figure indash and dotted lines to show in Fig. *1, byTt-he chains i7and sprocke'tsfi,

a chain 73'with a sprocket 7.4 mounted ona shaft 75, which as shown in Fig. 2 has keyed or otherwise. secured thereto a bevel gear 76. This gear isin mesh with asimilar gear 77 mounted on a spindle or shaft 78, which like the shaft 7 5 is journaled in the bracket 7 9 which liesin the obtusely angled portion of theband 21. The for clearness have been-omittedinthe small scale drawing of the apparatus shown in Fig. 1; but the sprocket 75 and a corresponding sprocket 80 have been indicated in the chain connections.

As shown in Fig. 2, the sprocket :80 is V mounted upon the spindle of shaft 78 and of ,20,

course is driven at the same speed as the sprocket 74:, since the bevel gears which connect these spindles75 and 732mm of the same pitch diameters. V

A chain 81 connects the sprocketSO with a sprocket 82, which as shown in Fig. 3 rides on the shaft .67. Upon the outer end of this shaft is a spur gear '83'which is in mesh with a gear 8-1, mounted upon the-corresponding endof the-shaft 37. Gear Be -is also in :mesh with a narrow faced gear 85, similar to the gear 83; gear 85 being fast to the end of the shaft 33. As a result of these gearconnections, the shafts 37, 33 and 67 will of course all be driven at the same speed. 4 4

Aside from the sprocket and chain connection leading up from the shaft 5, as above described, it is evident that the belts 3030 will tend to drive the shafts 33 and 37 at the same speed; but it is desirable to relieve these belts from ,any special tension other than that provided by their respective tensioning devices, sotha t it is preferable to use the chain and sprocket. connections and gears to the end that slippage between the ascending runs of the belts 30 and 30 may be substantially eliminated.

The tension upon the angle belts 49 is preferably quite light and in practice the weight of the pulleys 51, shaft 52, and arms 63 has been found sufficient since theweight of these parts tends to rock the shaft 52 clockwise around its pivotal axis, as viewed in Fig. 1., V V

The operation of the conveyer will now be briefly considered.

Papers delivered by the fly 10 to the horizontal belts 1 are carried in overlapped relationship toward the angle belt 11 which changes their direction of movement smoothly and with but little tendency to smear the freshly printed papers, preparatory to delivering them between the ascending limbs of the elevating belts 3030. These belts receive the papersbetween their nated 30 or .those designated30, proach each other during gears 76, 77

last

through, for example, 45

" to wipe across the surface of projection free faces and "carry them up in 7 their overlapped relationship 1 pastthe guide and 'tensioning rollers 28.

Since during their ascent-thesepapers are to be rotated clockwise,- as viewed in Fig. 2,.

throughananglewhich may be 45 or more, there is atendency for the several belts in each set of the same, vsuch'as those desigto apthe first half of their ascent, and thereafter to correspondingly separate from each other during the half of the ascent. This is due to the fact that the belts are under tension and hence tend to straighten out, while since a straight line isthe shortest distance between twopoints, the rotation of the upper shaft with respect to the lower shaft of-a given setof belts, tends to causethe two outermost belts of a set of three, toaproach most nearly themiddle belt of the set, half-way up between said shafts.

To make thisaction moreclear, let us assume that the. shaft 33 be rotated, not through 45 with respect-to the shaft 5, as in-the present case,

but through 180. In such a case, the-two outer belts 30 would actually cross and make contact with-each-other half way between the planes in which lie said shafts 5 and 37. r

Now this tendency for each'set of belts to narrow up in theiroverall width as they depart from the shaft 5, for example, until they reach a plane midway between those in which lie the'sha-fts 5 and 37, and to thereafter again separate fromeach other or widen out in their overall width as they approach their respective upper pulleys, is rather disastrous to freshly printed newspapers or the like, if such tendency be not counteracted; since during the first half of the upward movement, the outer belt in each set tends the overlapped newspapers and smear the ink, or said papers may be rumpled up or wiped over each other with equally bad results.

By providing guiding projections such as those designated 31. or the equivalent thereof, upon one side of each of these belts, and by causing these projections to ride in grooves in the guiding and pressure pulleys 28, this tendency for the belts 30 and correspondingly 30)-to thus play laterally toward substantially ob- Itwill be understood that'alternate rollers will engage, for example, a given belt 30, while the intermediate alternate rollers will correspondingly engage the apposed belt 30",

'and that theserollers are so staggered with respect to each other as to aflordthe requisite I grip of theapposedbelt portionsupon the at spaced intervals wherebyto grip the papersbetween the belts; but further they servevtomaintain a proper spacing between the'belts of each .set' and further serve to prevent "lateral vibratory motion of these belts'whi h also would tend to'-.smear the,

freshly printed papers. v 7 .While, especially'for short lifts, it is pos- 'sible to use other than flat belts for the conveyance of the papers from one level to am other while rotating said papers angularly during their translation. I greatlyprefer to i use narrow fiat belts such as I hav'eshown, v and to provide upon the nonpaper-engagingsidesot these belts.-such projections as those desi nated 31. which arepreferably.
