MACHINE non APPLYING HEADS To THE ENDsoFnoLLvs.
Application led December 26, 1925. Serial No. 77,892. y
T 0 all 'whom t may conccm: Be it known that l, FRANK HENRY Anson,
`a citizen ofthe UnitedStates of America,l
and resident of Iroquois Falls, Province of Ontario, certain new and Machines for Applying Heads to the Ends of Rolls, and do hereby declare the-following to be a full, lear, and exact .description of the same.
This invention relates to the mechanical application of paper discs' or heads to theends of rolls of paper and appertainsv p'ari release the roll to permit its removal with the heads applied. y
ln so far as, I am aware machines of the above mentioned type tok manually operatedv headers of limited capacity withrespect of the'length of rolls to be accommodated with the result the use o-f the machine has vbeen limited and, its operation necessitated practically constant attention uponthe part of the operative in ensuring` that the necessary steps beA taken for lthe application of the heads and release vo1 theroll at the proper periods.
An object of my invention is to avoid shis ,deficiency by the provision throughout the Wliolef`range usually encountered andl to provide for ,power op,- erated brackets:preferably` under automatic control whereby, subsequent tothe applica- V tion of the heads to the roll, and at a pre` determined pressure such brackets are relieved of pressure and subsequently i'eleased to permit of its removal, thus simplifying the operation and', in addition to mak- .siniplifying Iits oiperation'with resultant increase in capacity. y y n Heretofore the supporting bed of the platform. upon which the paper roll was su ported been made' stationary with tne Dominion of Canada, have invented ,i useful Improvements in the paper heads toV have been confined Fig. 2.,
of a machine lengths ofv roll` ing the machine more universalin vits utility,
result that should the roll move longitudi-y nally under the pressure of the movable brackets, the roll itselfA or its outside wrapper would scrape along the platform and-be torn, especially vin the case of large rolls which ,are of considerable weight and a further object therefore ofv this'inventionis to avoid the possibilityfof such damage by Athe provision of an antifriction bed or supporting portion vwhich will facilitate move- Vment of the roll and thus prevent scraping of the latter.
A still further in proper alignment with the roll irrespective of the Adiameter .of the flatter, this featuse, inv conjunction with the construction providing kfor the accommodation of a` wide range of roll thoroughlyy flexible and universally. adaptable machine vthan has appeared heretofore.
The above with further objects and advantages ywill be hereinafter more fully delengths, providing lfor a. more object of the' invention coni -Vsists in the provision of adjustable supportsy for the heads carried by the applyingv brackets so that said heads can be adjusted my inven-v scribed and particularly pointed out in the ,e
appended claims. e .e
For full comprehension, however, of my invention reference should be had to the accompanying drawings forming a part of this specification, in Whichthe same reference characters indicate like` parts and wherein Y f Fig. l is a longitudinal section of my improved kroll press and head applying machine, the section Fig. 2 is a plan view' of the machine; Fig. 3 isa cross-section on line 3-3 Fig. 3; and l control.' A
y Referring now to `the drawings, the bed of the platform Afor supporting the'rolls to be headed, consists of a seriesv of rollers 9., horizontally disposed in yparallel relation and supported at their opposite ends by trunnions 3 bearingv in Z-bars 4 extending longitudinally of t-he machine and supported by vcto-extending Fig. l is a Wiring diagram of the motorvw I-beains 5 suitably mounted upon the foundation of the machine.

These rollers are individually rotatable and i constitute `ant-ifriction elements of the plat-` form upon'which the paper rolls which are to be headed are` placed, the rolls extending `outer; side ol'fthe plate beingcprovided with transversely of the rollers and the centre portionsvoi' the latter being concared or reduced to provide a depression ior the reception ot' rolls to prevent accidental movement oil the platform.
Upright brackets aresupported upon the Each ot. the` brackets preferably consistsota -tiat plate 6. arranged transversely across the platform perpen-dicul v thereto, the
braces-8 at either side `and eitendingv do wardly on the outer sides ot the '-.beai thewheels being mounted upon the lower endsof these braces.` The plate G oi `cach bracket. is backed by a casting 9 p` I top and bottom anges l0 and a .ce largement recessedy atll the. frontend communicatingwith Va vertical slot l2 in plate 6. bloc-lr 13 mounted therein for verticamovement7 such movement beingrimparted theretoby ya vertical-shaft l--.in screw-threaded engagement with theebloclrand extending upwardlytherefrom loosely through the enlargement and in screw threaded engagement withy top` flange l0 above which the shaft is itted with a hand wheel 10a.l llaeh block carries a pin l2 which entends horizontally outwardlytherefrom through slot l2 in the plate. 6 and yby rotatingbT lthe shaltV through t-hewrnedium otihandfwheel iGa'thc blocl; l5 is causedv to move up,v or down and through it the level of .the pin is raised or lowered with respect to the platform. rlhe pins l2 are utilized to support a supply o head,- or paper discs ready tor application tc the paper roll and to enter the a l hole ot the roll when the brackets are moved inwai to-apply the heads and the adjustment l' described enables the pins to beaccu moved vertically into exact horizontal at ment with a roll irrespective ot theA diameter of the latter, thel slot l2 and recess il bei designed 'for the accommodation oi" the dii.- ierent.diameters ot' rolls likely telic encountered.
Power apparatus is provided tor moving thefbraclet-s longitudinally over the glatorm and `nhile any suitable apparatus may be employed, one arrangement which'is pecially suitable for the aurpose will now bedescribed.
This power drive consists ot 'an electric motor l5 operatively connected to spindle boltsV 16 by -means ctv-.nich the brackets are movedl Asshown in the drawing the Eaclrrecess ll accommodates a.
motor is supported transversely at one end oi the platform, theopposite ends ot the motor shaft l? having worms 18 mounted thereon and meshing` with worm `sears carried by spindle bolts 16 one o' which latter is arranged on the outside ot each beam 5. These spindle be extent. throughtlie -ength ot' the platt rm and are each rotatably supported at the center by a bearin@` 19 at the motor enf by bcmings 220, and at the opposite end by a bearing 2l. The
spindle bolts are respectively formed with right and letti hand threads opposite sides or the central bearingsain. a 'e in en.- gagement with nuts. 29 carried ny each ot the brackets so that when driven by themotor these spindles cause Vthe bra -liets to move inwardly towards each other or outwardly away from each other over the platform in acc relance with the direction ot rotation ot the motor.
ln the operation et the machine with the ln'aclets spaced apart as illustrated and the pins siuinortinsa)` asupply ot heads the outermost heads-are coated with adhesivemateri anda roll indicated at 241 is moved upon the platform between the braclets7 the pins being then adgusted into alignment with the axial line ot the roll.' rlhe motor is tien started inthe forward direction to move the brackets inwardly towards the roll thus pressingy the outermost heads against the ends ot theI roll to which the heads adhere. It the pressure upon the roll at this time causes it to move longitudinally such movement is accommodated by the rollers 2 and tearingv ot the roll or otits w upper .is prevented. lli/Then sutticient pressure has been applied the motor is automatically stopped and then driven in reverse directionl to withdraw the brackets thus treeino' the roll and permittinggit to be .removed from the platform.
The operation of motorn 15' is controlled by a conveniently located Vfloor switch operating as shown -by diagram in Ll wherein 25. is a push button switchV for torward operation ot the motor, 26 a push button switch for reverse operation oi the motor, 2T a push button switch for stopping vthe motor, 28 a limit switch7 29 a double pole relay, 30, 30n a reversing panel consistingoi two 2 pole contactors and 31a vgravity reset current operated relay with adjustable calibration. When starting switch closed a circuit is umile from contact ik et line switch to Contact 33 through operat coil ot' double pole relay 29 and coil to the starting switch by wire 35 and bach to contact 40 of line switch through wire 3G, This circuit closes cont-acts of relay 29J short circuiting the operating coils ot' current operated relay 31 so that the latter will not operate on the start and keeping contacts 3?' and 38 closed. The motor circuit follows from ficy ` contact A32 topcontact 33jof yrelay 29 through `described through the limit switch lead 32 to coiitactBS and back to contacty 38 on Vthe current operatedy relay 3l through contact 37 to-aiid through the operating coil of pole contactor` BOGto contactl `39 of` forward starting switch 25 and back to contact 40 of line switch by wire 36, thus pulling in all 3 contacts of contactor starting vmotor in forward direction.
Switch 25 is lield closeduntil motorg'aiiis speed, the heavy starting current at this time being short` circuited and not passing through the coils of current operated relay 3l, the contacts 37 and 38 of the latter ,remaining closed. When the motor has gained speed the current drops down to nor-v mal. The switch 25 is then released by the operator and allows the relay'29 to open up its main contacts forcing the current in two legs of the motor'circuit to pass through the coils'of relayl.v At this time contactor 30 does not dropout since lthe auxiliary contact 4l on coiitactor Ofst-illr maintains a circuit throughl the operating coil by way of auxiliary contact 41, wire 42, reverse switch 26, wires 43 and 36 to contact 10.
The forwardly operating motor moves-the brackets against theroll and the pressure increases'and with itthe pressureof the current increases until the latter reaches a predetermined pressure operated relay 31 has been adjusted `and at this time the contacts 37 and 38 are caused to open thus breaking the circuit through the operating coil of contact-or 80,
opening the contactsv thereof and 'automatically` stopping the motor. When the motor stops all relays'are restored'to -normal condition. 'i
To withdraw the brackets from the `roll they switch 26 is closed to reverse the operation of the motor, the closing of the reversev verse direction a distance limited by the opening of .the limit switch by the lengagement therewith of a stop carried by the bracket, this stop engaging .the button on the limit switch at 47, causing the contacts 87, 38 to open thus breaking the 'circuit Y' through the operating coil of contactor 30a,
opening contacts thereof and automatically stopping the motor. t- The motor being stop- 30 and :p

From the above it will be'seen that I have rolls varyii'ig both in and of operating upon same without likelihood of damage theretoand a 'machine iny which the rolls can be handled in afquick and efficient manner. Furthermore the operation of a machine constructed according to the above simplifies the operation to be performed'and the automatic stopping of the power-driven brackets at a certain predetermined pressure precludes the possibthe machine due to the application of excessive pressure,Y That I claim isfas follows:
