Myflim'proved device is more particularly applicable for holding in osition a roll of heavy paper board, from w 'chsuch articles as cartons are made, in position to be fed to a coating-machine, by which the material is coated to render thesame waterproof, or a cutting-machine, by which blanks of roper dimensions are severed from the we pre- Among-the-objects of m provide paratory to scoring thesame.-

invention are to a slmple and readI yoperabledev1ce of this character whereby. the roll-support maybe accurately adjusted to a machine,so as to: maintain the entering web as it is unwound from the roll in proper alinement with the feed-rolls of the machine, to provide a-device which is capable of sli htlateral adjust-' ments, and a device which ocks the roll-sup:

hi the drawings, A designates as I a whole the feed end of a machine, as a coat:

ing or, cutting machine, in which the webfofoo A A designate feed-rolls bywhich tlie web l. 7

is fed into the machine, and a a uide-roll located in position to bring the we in horizontal alinement with the coactingfaces of said feed-rolls.

rear of t e machine A and sposed transversely to the path of the web to said machine. D deslgnates as a whole, a carriage su ported on said base and movable longitudinally of the base, and therefore transversely to the pjath of the web as it is-fed into said machine.

E designate standards which rise fromsaid carriage and support at their upper ends said roll B. Said base is provided with suitable. tracks or ways on which said carriage is su As herein shown, t e f orted and moves.

ase comprises an elon ated open frameembracing longitudinal si e members a and end members 0. The longitudinal members 6 thereof are provided on their inner faces with inwardly-opening channeled tracks 0 which receive ugs d, projecting laterally from the lon 'tudinal side members (1 of the carriage.

C desiglnates a base or slip ort locatedin 7 Pre erably said lugs are provided with rollers d, whichenter said channeled tracks C It I will be dbserved that the'end member 0 at one end of the base is located'below the channeled tracks 0' in said frame topermit the carriage to be removed entirely from the base.

d d, rising from the end members d ofthe 1 hev standards E are herein shownv as bolted attheir lower ends to verticalflanges carriage; Said standards are providedat their up er ends with upwardly-openin recesses w 'ch receive bearing-blocks-E, i aving upwardly-opening bearing-sockets; that Y receive'trunnions b, formed. on theiprojecti'ng' tends of the core-B, aboutwhich the web is ironed w ndsaidxstandards E arem..

- Said horizontal arms E E are 'wardly, as shown in Fi 1.

vided at their upper ends with horizontal rearwardly-directed arms E E which consti-tute ways or su ports over which the projecting trunnions' of the core B .pass as the roll Bis approachin the bearings at the upper ends of the stan ards E when said roll is eing placed in position on said standards.

rovided at their outer ends with verticall -swinging hand-levers E', which normally han down- Said and-levers E are provided for t e urpose of assisting to raise the roll Bite the evel of the arms E when the roll is bein placed upon the standards. In practice t e roll-B 1s delivered to the carriage over a suitable inclined v for moving-said carriage longitudinally of its base-or support consists in this'instanceof a rotative screw-threaded shaft F, having 'ht and left screw threads at the opposite si' es of its longitudinal center. One end of said rotative screw-shaft engages a nut G,

thatis fixed"bybo'lts or other suitable means in a slot or-q ening din the flange d,'before referred to, igs. 3 and 4. 'The other end of said ro'ta'tive screw-threaded shaft'has screwthreaded engagement with a nut H, whichlis attached,'by means o'f-bolts ,to the upper 'face of the adjacent end member a" of the Zbase.

' Said shaft is rotated by means of a handlengthwise of its base,

wheel F, located intermediate the right and left hand screw-threaded portions of. the

shaft. With this construction rotation ofthe shift 'by said hand-wheel moves the carriage the direction'o'f movement depending upon'the direction of movementof the shaft. Byireason of the right and left handed screw-threaded arra ement ofithe sha'ft the endwise movement of-t ecarriage is accelerated beyond that which would be'imparlted by a shafthavinga single screwthrea Moreover, the construction described ermits the carriage to be moved practica yjto the endmember of'the base or support without the necessity of lacing the hand-wheel outside of said end member. It will be dbserve'd that the arra ement of the screw threaded adjustin -sha" is such that the carriage is -positive y locked in an adjusted positionby the same means which iso suited to shift the same.

he construction described permits the.

roll B toj-be readily placed inv 'osition on'the carria e and to be rapidlyshifted' endwise with ut fllttle manua exertion -to register the web with'the feed-rolls o'f'the machmeA as'it is unwound'lfrom its roll. Inthis manner accurate registration of the web to the carriage and provi and vertica feed-rolls of the machine is assured, notwithstanding that the web is being unwound off of anirregularly-wound roll.
