To all 'whom :it may concern: i

` a citizen ofthe United States Be it known that. LlViLLiAii A. JorniN,

, residing at Lawrence, in the county of Essex and State of 4llfassachuse'tts, have invented a ertainnew. and useful Improvement in Bag or Liner Spreading Devices, of which the. folf lowing is a specification, reference being had therein to the-accompanying drawings.

In putting up package goods by machines paper cartons are very extensively used for the package, and for'cei'tain classes of goods A itis important to have a'lining for the car'- ton. The cartons usually come. in knocked down form andare usually set up one at a time as they are to be filled. In many cases it is the practice to insert the lining by hand after the carton is set up just before filling.

When the lining isirst put into' the carton,

if done by hand, its sides will bulge in, and

it is important to have the lining squared out 'to closely fit the interior of the carton before the goods are delivered into it 'from the hopper. Sometimes paper bags are employed instead ofrartons and when such are used they should be opened out when positioned to receive the goods from the hopper or other feed device.

The object of the present invention is to provide an attachment to the filling machine whereby the paper receptacle whether.` a

paper lining or a paper bag. as the case may be, will. be opened or spread lout into proper shape before the material is delivered to it and whereby theopening of thesp reader :controls the delivering of'ma'terial into the carton as well as spreads the lining. The invention .will be fully understoof from the following descriptionta'ken in connection with the accompanying drawings and the novel features will be pointedoiit and clearly defined in the claims at the close of the specification. j i

view of a carton -withthe lining inserted before .it is. squared out .by the spreader. t is a side view showingthe spreading wings about'to .enter into the carton and Referring now'to the drawingsf-l is the hopper through which the material is delivered to the package. yAttached to two opposite sides of the lower part of the-hopper' are two downwardly extending side plates 2.'

The outer edges of each of these-side plates 2 have outwardly flaring portions 'toward the lower ends-which form cam surfaces for the purpose to, be hereinafter described.

',Preferably'the lower portion .4 below the cani surfaces 3 is straight. A lever .5 is ful'crumed intermediate its ends? at '6 toa.

'hanger 7 which depends from a stationary v.support 8. One arm of said lever ,5 is pro.

vided with a roller 27 which engages with a cani 9 mounted on a shaft 10 and the other arm of said-lever is pivotally connected at 11 with" an upright. portion 12 of a 'crosshead 13. A spring 24 holds the roller 27 in constantengagement withthe Cain. Preferably there are two of these cross-heads and levers, one on the outer side of each off-fthe two side plates 2. Between the two side plates 2, 2, are the two downwardly extendingwing plates 14, 14, which are pivoted-,to the crosssheads 13,13, and are wide enough to close the entire width of tlie'space be-- tween the two side plates 2, 2, so thatthe two side plates and t-he two wing plates together form a Vfour-sided chute or mouthpiece for the hopper. The wing plates are so controlled that normallyfthey converge downwardly until theirlower ends are in contact with eachother thereby .closing the lower end ofthe. 'passage-between the side I plates2,2. i

As shown inthe .drawings the means for pivoting the twowings .1'.1'; 14`is to foriii'- each of them with a pair of eaPs 15, one at" g each ledge neartlie upper end. -A .shaft 16 extends-acrossthe full width of each wing and extends through both ears 15 of the wing so that the wing is pivoted thereon.

Each of said plates also has V'another pair of ears 1T projecting outwardly therefrom at some point below the iirst pair ots-aid ears l5. Connecting each pair of ears 1T on each wing is a. shaft 1S carrying a roller lt) which'engages' the outer edge of the. side plate 2` A spring 20 connects the two shafts 15,18, together' and the tension of the spring issutlicient to -retain the two rollers ll), lJ, in Contact with the outer edges of the plates 2, Preferably the upper ends of the wing plates 14, 14 are curved upwardly and outwardly.

The upwardly extending varm 12 of each cross-head 13 is formed with-a vertical slot 2l."l Two pins'22, 23, one above the other, project from each of the sides plates 2 outwardly through the slot 21 forming guides for the cross-head.

gl The shape of the cam 9 is such that'afterthe high partof the cam which' is shown in Fig. i as in contact with the roller 27, turns soF-thatt-he lower part'of the cam comes in contact with the roller, the lever 5 will bef-turned on its fnlcrum by the spring 24 25 land the cross-heads 13 will be moved downward. As the cross-headsmove downward' the rollers 19 engage lwith the cam edges f 3 of the side plates 2 thereby spreading or opening out the lower ends of the wings 14 as the wings 41&1 are carried down by the cross-heads. The lcarton 25 containing the lining 26 which will previously have been positioned 'um below the side plates 2 will be; in posiiion for the lower ends of the wings 14 to enter the lining while the wings are still in theirconverging positions and' as; the wings are carried down andspread apart they will spread open the lining'of the carton until the wings are spread out into (par-alici position, as shown by the dotto lines in'h`ig,.v 1, which is the limit offtheir outward spread; During the' latter part of. the downward movement of the cross-heads the rollers 1 9 will engage the lower straight edges`of the side -plates 2 and. the wing plates will then move down parallel with each other. Preferably the plates should be so proportioned with reference to the bags or cartons which are used that when the wings 14, are in their spread out parallel posit-ion they will lne/opened just sufficient lto spread Iopen* the lining to the yfull lwidth of the carton.

:A paper bag# which may be used aslthe package or container without any carton may-'be opened inthe same way' as described for o ening the lining, if `properly lsup- '.,zpote Vin an upright/position beneath the spreaders. f

-v !.lhe cam shaft 10 may be rotated by any suitable mechanism and it. is not deemed necessary to 'show' any' particular driving` f means therefor.
