l To all 'id/tom it may concern;

Be it known that I, FRANK E. KEYEs, of New York, in the county of New York and State of New York, haveinventedcertain new and useful Improvements in Machines for Making Articles from Pulp; and I do j machine that the pulp. will be supplied evenly to and wound upon atformer in such manner that the bottom of the article can be applied during the forming of the body portion of said article, and to construct the machine in such manner as to facilitate the application ot' the formers and their remova'l with the finished article.

With this object in view the invention consists in certain novel features of construction and combinations of parts ushereinafter set forth and pointed` jout in the claims. p l if In the accompanying drawings, Figure l is a sectional View, partly in elevation, `of a machine embodying my improvements.- 'Eig a side view `partly in section. Fig. 3 is a plan view, Fig. 4 is adetail View showing the wheel QOand locking means. EFig. 5 is a view of the deckle ring (l, and Fig. (3 ris a vView of the `fixed ring 9.

1` represents the main frame ot' the machine, to one side of which apulp tank'Z` is located andthe latter is provided in one fwall with a pulp inlet 3 guarded by a shield 4.-. An overflow pipe 5 projects upwardly .into the pulp chamber 2 'and `regulates the level of the/pulp in the latter. l

A deekle ring G is located on one wall of the pulp chamber and from this deckle ring to the opposite wall of the pulp chamber, a molding cylinder or drum 7 eXtends,--'sa.id molding drum being mounted upon a shaft 'S having suitable bearings in the main frame vland this shaft may be provided with `any suitable means for rotating it. The mold. mg drum is made at'one end with a closed heady,v4 and the peripheral portion of said drum isreticul-ated, as clearly shown in Fig. 1. `Theopen end of the molding dnum 7 is rotatable onfa stationary ring 9 supported by suitable spokes l0 projectingfrom a hub 11. Two partit-ions 12'and 13 are located within the molding drum andmade rigid f with the fixed ring 9. The partitidnlQ is vertically disposedl while the partition 13 is disposed in antiinclined position so that.its lower enchwill Vterminate near the leve]h of the pulp in the pulp chamber 2i The. outer side wall of the pulp lchamber is provided near'its lower` end with an opening 14 with which suitable connection is made forthe 1- purpose or` creating suction within the inoldnu muc.

of water. It will be observed that'that portion ofthe space within the molding'drum between thevertical partition l2 and the upjper face of the diagonal partition 13 will be `isolated vfrom the action of the suction created so that as the druinrotates and passeslthrough 'the 4pul in the cl'iamber 9, the pulp will be caused to adhere` to the reticulated peripheralwall oli-the drum fromthe time that said wall passes the partition 13 andenters thcpul'p until the upper end'of the partition 12 ispassed, As there will be no suction iu that portion of the molding drum to theright of the partition 12- in Fig. 2, the sheet ot' pulp vwill be released from said molding drum at the upper end of said parftltion 12 and. will he transterred to a former 15 onl which thebody ot the cup or otherl article is constructed.

I provide means for support-:ing a series of Y formers l5 and the construction .and operati on ot these means plained.

ik triangular 'trame is located upon the main frame l and hinged at one end thereto, as shown :it-1T. At the apex of this trianguiar-traine. bearings 1S are provided for the accommodation ot a shaftll) which is of suliicient length to extend overthe pulp chamber andthemolding drum therein. A wheel 20 is fixed, to the shaft 19 and providedI with a series ot' pins` Zito `receive sleeves 22 located within andrigidwith the will now be ex-4 "cated on the shaft 19, near the free end of the latter, and secured thereto by means of a set screw 24-said sleeve being provided at each `ofits ends with a [lange 25. The

tlan'ges25 are perforated for' the passa e of rods 261which project from arms 27. ach

' arm 27- has connected. therewith a head or disk 28"which serves to hold 'in' place against the end'I of the ad'acent'former 15, a` diskA 29 of' pulp board w ich forms the bottom of the cup constructed on the former. The disk 29 is held inposition and the former 15 is prevented from longitudinal movement on the pin 21 by means of a spring 30,--said spring-'being secured at one end to rod 26 and bearing at its other end against flange 25 at the outer end ofA sleeve 23. Each arm 27 is provided with la finger piece 31 for moving the same when avformer is to be applied to or removed from the machineand each arm 27 .is normally locked in position by the engagement of one end thereof with a notch 32 in thefree end of the shaft 19.

During Ithe formation of a cup, the wheel 20 and the shaft 19 to which 1t is secured will be locked against rotary movement by means ofa latch lever 33 .having 'a tooth 34 to engageone of a series of notches 35 in the periphery of the Wheel 20 and such engagement is normal hinged frame 16 near'ithe l ly maintained by means o suitable 'spring 35. i

A rodfjl is secured to the top of the main frame 1 and passes 'loosel through the ree end of the latter. This rodI projects an appreciable distance above the upper face o the .hinged frame 16 and is provided at its upper end with a nut 37. Between this nut and theupper face of the hinged frame 16, a spring 38 is located for the purpose of maintaining 'i proper yielding -pressure'of a former against the moldin' rum. The pressure of the rmer aga 'nst the molding drum "or relatively thereto', can be regulated by means of a screw 39 passing through the hinged frame -16 adjacent to the free end of the latter and engagine the top of the main frame l, as

Aclearly sihown in Fig. 2.

From the construction and arrangement ot' parts. above described, 1t will be seen that l, asthe sheet of pulp carried up by the reticulated molding cylinder, reaches the former disposed immediately over the same and as the sheet of pulp cannot be hcld by suction the partition l2. said sheet of pulp wi againstrthe drum beyond the upper eng of be transferred to the former and as the latter is rotated, the pulp will be wound upon it to form the body of the cup or other article to be made. As the wetpulp is thus wound and pressed on ih e former it will so engage and bc pressed against the periphery ot' thc pulp disk held by the former, that a permanent joint will be made between the wet pulp and the pulp disk and thus thebottom of the article is secured in place during the formation of the body portion of the latter. YVhen a cup or `other article shall have been completed, the wheel 20 can be released and turned for moving the completed article away from the moldin another former in positionover the molding drum. The completed article canf'then be easily removed from the machine undl another former placed in position. I,
