Application filed May 2l, 1904. Serial No.y 209,048. l

Be it known that I, FREDERICK J. MoTz, a citizen of the United States, and a residentor1 the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented a new and lmproved Machine for Making Paper Articles, of which the following isafull, clear,and exactdescription.

My invention resides in a certain novel machine by which seamless paper articles may be produced, the machine being of that form having a vat and means for automatically submerging foraminous shapes therein and withdrawing them therefrom and exerting through the shapes a Huid movement during the time of their submergence, thus causing the pulp to adhere to the shapes, so that after they are withdrawn from the vat the pulp may be allowed to harden or set on the shapes to form the finished articles.

I will nowspecilically describe the preferred embodiment of my invention, reference being had to the accompanyingdrawings, forminga part of this specification, in which4 Figure 1 is a longitudinal section of the machine. Fig. 2 is a cross-section thereof. Fig. 3 is an enlarged sectional view of one of the suction-heads, showing one of the shapes engagei'l therewith and illustrating the automatic action of the suction-cut-off valve. Fig. 4 is a detail perspective view showing the preferred manner of forming the shape and illustrating' the manner in which the pulp accumulates thereon, and Fig. 5 is a detail of one of the spring-closed valves.

10 indicates a vat Vfor containing the pul p, which is supplied to the upper part of one end thereof through a pipe or conduit 11. 1n said -vat is arranged a horizon tal partition 12, forming a false bottom and having at each end a vertical partition 14. Said partitions 12 and 14 are in watertight engagement with the .sides of thevat and form, therefore, a continual or endless passage through which the pulp may be circulated in the manner indicated by the arrows in Fig. 1. 15 indicates any desired form of pump-for instance, a ifan-puml) for maintaining this continual circulation of the pulp, by which means the pulp is kept at an even consistency and the solid parts thereof preventedfrom settling in the bottom of the Vati 16 indicates aplugor eq'uivalen'tconnection for draining the vat. Mounted onthe sides of the vatarerboXes 17, in which are mounted to turn the journals 18 of a suction-drum 19.

2O indicates a suctionpipe Vextending through one of the trunnions 18, whichishole lowed for this purpose Aand projects downward into the suction-drum. Said pipe 20 is adapted to have communication with any suitable vacuum-forming apparatus, so as to exert a continual suction within the drum 19. The remaining or solid journal 18 of the drum 19 has fastened thereto a pulley 21, by which` means or by any other means suitable forthis purpose a continual rotary movementlma-y be given to the drum.v As here shown, the pump 15 is driven also by abelt connection 22 from the said remainingjournal of the suctiondi'um 19. v

Communicating with the interior of the suction-drum 19 and passing radially there-A from are a number of stout tubes 23, each provided with a Valve 24, having a spring 24L or other suitable means for normally holding them closed. (See Fig.

e.) The valves 24 also have operating' lingers or handles- 25, in the path of which is arranged a segmental track 26, suitably supported at one side ofthe tubes 23 by any desired means-for example, by the rods 26. (Best shown in Fig. 2.) One end. of the track 26 is located j ust above the upper edge of the vat 10, while the opposite end is located some distance above the top of the Vat. The drum 19, with its attachments, is intended to turn toward the lirst-named end of the track, as indicated by the arrow in Fig. 1, and the result, therefore, of the peculiar arrangement of the track and its l relation to the operating fingers or handles 25 of the valves 24 is that as the tubes 23 dip into thef vat the handles 25 strike the low end of the opened, allowing the suction within the drinn 19 to be exerted through the pipes"23."" This'- condition continues as the tubes inove'throughy the vat and until the tubes rise above 'the'vat sufficiently to clear theoperating arms or han i o'e d les of the valves 24 from engagement with The special advantage of this operation will 1 be set forth hereinafter.

4 Each suction-tube 23 carries at its outer end a-suction-head 27. rlhese heads are, according to the form of the invention here illustrated, essentially pan-shaped and provided with broad edges or marginal faces 28. (Shown best in Figs. 2 and 3.) The outer ends of the tubes 23 at the points where they open into the suction-heads 27 are commanded by sliding cut-offs 29. Said cut-offs are connected to stems 30, and the stems have springs 31, applied so as to keep the cut-offs normally active. The inner ends of the stems 30 are turned laterally, as indicated at 32, and project through openings 33 in the faces 28 of the suctionheads, so that when the shapes are placed in position on the suction-heads, as will be hereinafter fully stated, the cut-offs 29 will be automatically moved to open or inactive position. 1n order to strengthen the machine and also toassist in holding the shapes in position,- I provide two annular bands 33, fastened suitably to the Sideedges of the suction-heads 27 and formed with radial slots 34, the slots lying respectively in transverse line with the faces 28 of the suction-heads 27.

,-The shapes or forms may be of any size and contour desired., this being dependent upon the shape of the article to be formed, and a number of shapes of different sizes and forms may be used in the machine at the same time. As here illustrated, each of the shapes comprises a framing made up of a relatively coarse wire mesh 35, with a binding 36 of wire or the like. Over said mesh is arranged a liner screen 37, of suitable metal, the screen 37 being that on which the paper article is formed I and its shape being that which it is desired to give said article.-

In Fig. 4, a, may be taken to indicate the pulp as it gathers on the screen 37 during the formation of the article within the vat. Each shape is also provided at its upper side with a hook 38, adapted to engage over the outer edge of the suction-head to which the shape is applied, thus holding the shape in position. The shapes are also provided with laterallyprojecting studs 39, which may, il desired, be formed as continuations of the bottom bindingbar 36, the said projections 39 being adapted to engagein the slots 34 of the bands or plates 33, thus guiding the movements of theshapes when engaging with and (.lisengaging from the machine and assisting in holding' the shapes properly in position. Reference to Fig. 3 will show the relative position of the shapes and suction-heads when in operation, from which it will be seen that the vhooks 38 engage the outer ends of the suction-heads, while the inner portion of the binding36 of the shape engages the projected part 32 of' the valve- Stem 30, thus moving the cut-oli' valve 39 to inactive position, as explained. This movement of the cut-off takes place the instant that the shape is inserted into the machine, and a closing movement takes place by the operation of the spring 31 the instant that the shape is removed from the machine. lt will also be observed that the binding 36 or the edge of the shape bears around the broad face 28 of the suction-head, forming an essentially hermetic connection therewith, the effectiveness whereof is increased immediately after the inception of the operation by the accumulation of pulp around the edges of the shape. 40 indicates a suitable frame or superstructure which is erected on the vat and which together with the side walls of the vat support the two guides 4l in which the projections 39 run and by means of which the shapes are automatically moved into proper position on the suction-heads and out of the same. The said guides 41 extend from the top of the superstructure 4() tangentially toward the wheel formed by thesuction-heads, tube, and drum and inward to the inner edges of the suction-heads, at which point the guides take a circular course concentric to the journals 18 and pass downward into the vat and upward out of the same and finally extend from lthe rotating wheel tangentially upward to the top of the superstructure. Two of these guides are provided, one being arranged at each side of the wheel, and the guides are preferably channel-shaped in crosssection, so as to receive and properly hold the projections 39.

1n the organized operation of the machine the shapes are introduced between the righthand ends of the guides, (assuming that the wheel is turning in the direction indicated by the arrow in Fig. 1,) with the projections 39 engaged in the grooves inthe guides. The shapes will drop down between the guides until the projections 39 enter two of the slots 34, whereupon the shapes will move with the wheel and will be simultane'ously run downward between the guides until the concentric portions of the guides are reached by the projections-39, whereupon the hooks 38 will engage the outer ends of the suction-heads, and this, together with the engagement between the projections 39 and the inner end of the slots 34, will arrest further independent movement of the shapes. As the shapes take this position they engage the parts of the stems 30 and automatically open the cut-ol'ls 29. I t should be notedthat suction cannot be exerted through the heads 27 until the valves 24, corresponding with the heads, are opened. The rotation of the wheel is continued until the shape is submerged in the vat, and at this period the handle 25 of the valve 24, corresponding to the said shape, strikes the track 26, and said valve 24 is opened. -Suetion is then exerted through the head v27, tube 23, and drum 19, and the water is drawn through IOO IOS i IIO the for'aminous shape, this current causing the solid parts ot' the fiber to cling to the foraminous shape and Vform a covering oi' a size and form corresponding to that of the shape. The shape continues this movement through the vat and finally rises at the other side. lt should be observed, however, that the suction is not cut oii until the valve-handles 25 disengage the high end of the track 26.

This allows a certain period during which at-l mospheric air is drawn by suction through the shape and layerof pulp thereon,thus effectively withdrawing from the pulp all surplus liquid and leaving the pulp relatively solid on the shape. When the high end of the track 26 is left by the valve-handles 25, the projections 39 of the shape begin to run into the second eccentric or tangential ends of the guides and are thereby caused to move outward until'linally they are completely disengaged from the wheel, as Fig. 1 illustrates. At this time the cutoff 29 will be allowed to become active, and the suction-pipe 23, corresponding to the shape thus moved out of engagement with the suction-head, will be closed. .In connection with this cut-01T device it will be seen that while the valves 24 actually control the beginning and end ot' the suction period the valves or cut-offs 29 prevent breaking the partial vacuum or sucking the pulp into the suction-drum 19 should one of the shapes miss its position in the machine or should it become displaced therein. The shape with the pulp clinging thereto, as explained, should now be dried and the pulp allowed to set, thus forming a linished seamless paper article corresponding' accurately to the shape on which it was produced. The pulp which is run into the vat is beaten and prepared in the manner usual for paper-making' and is then Alurth'er mixed with water to adensity of approximately two to three parts ot' pulp to one thousand parts oi' water. The Afiow ot' the pulp into the vat should be regulated so as to keep the level ot' the mixture therein close to the upper edge oi the vat.

l provide means for automatically taking' the shapes with the pulp clinging' thereto from the machine, transljiorting the shapes to a suitable means Vlor artiiicially drying the pulp and for disengaging the linished paper articles from the shapes and then returning the latter into the machine, thus allowing the operation ot' `forming' the paper articles to go on continuously and avoiding the necessity oi' manually handling' either the shapes or the paper articles during the period of formation. According to the form of the invention illustrated in the drawings this means for automatically handling' the shapes comprise an endless carrier running over the top of the superstructure 4() and formed oli two endless chains 42 with transverse rods 43 pivotally mounted on the links thereof. Said rods are provided with hooks 44, adapted to engage in openings 38a, formed in the hooks 38. hooks 44 are also provided with projecting iingers 45, adapted at a certain point in the path of the carrier t`o strike a wedge-like detent 46, thus throwing back the hooks 44 and allowing them to disengage from the walls in the orifices 38. As the carrier moves in the manner indicated in Fig. 1 its hooks 44 successively engage in the oriliees 38 of the shapes as they are successively raised from the wheel by the eccentric or tangential form ot' the guides 4l. The shapes with the pulp adhered thereto are then moved by the carrier into the drying-room or other means for artificially drying the pulp. rlhe carrier moves continuously through the drying-room, and the arrangement is such that when the upper run of the carrier passes from the drying room or apparatus the pulp will be set or hardened, thus forming the Finished seamless article. At a suitable ppint a blower 47 is located, which causes a blast of air to be forced through the foraminous shape and to-impinge against the iinshed article thereon, thus blowing the article from the shape and completing the operations on the article. The carrier in continuing its movement advances the shapes into\position to reenter the machine, and at this point the finger 45 strikes the said detent 46 and causes the hook 44 to rock backward, thus automatically releasing the shape. Various other devices may be provided for automatically removing the shapes vfrom and engaging them with the machine, and in this connection l would mention that the shapes may be attached either permanently or removably to a carrier chain or chains which. are preferably endless and whlch are run with.

the shapes through the guides 4l, these chains, therefore, moving the shapes continuously through the machine out to the d rying-room or other drying means and thence back into the machine, thus maintaining continuous operation and insuring' rapid work.
