To all whom it may concern:

Be it knownthat I; FRANK E. Kin-es, of New York, in the county of New York-and State of New York, have invented certain new. and useful Improvements in Machines 'for, Felting-Pulp; and I do hereby declare the following to he a full, clear, and exact description of the invention, .such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to in] movements in machines for felting pulp an 'nlorc'particularlyto such as areadated to effectually transfer pulp, by means 0 mold and couch rolls to forming rolls,+one object of the invention being to. provide simple and efficient means for supporting and controlling a plurality of forming rolls above the ,couch roll, so that pulp will be roperly wound or formed on one of said. orming rolls ata time.

A further object is to so construct the machine that' the-carrier for't-hc forming rolls .can benormally locked against rotation and yet be permitted to rise uring the accumulation. of pulp on one of the'forming rolls,

and so that said forming-roll carriercan be easily unlocked and thenrota'ted to move a roll haviuga tube formed thereon, from the couch roll and simultaneously to move another forming 'roll into'position over the.

couch roll, ready to rcceive'pulp from the couch roll, without necessity of stopping the operation oft-he machine.

A further object is to provide simple and efficient means for breaking the vacuum within the mold and couch rolls adjacent to the juncture of said rolls and adjacent to the juncture of the couch-roll and molding roll, to cause the proper transfer of weak.

pulp from the mold roll to the couch roll and from the latter'to a forming roll.

A further object is to provide efficient. means for counterw'eightingflhe forming rolls and their carriers.

' With these and other objects in view, the invention consists 1n certain novel features of construction and combinations of parts as hercinafter'setforth and set forth in the In the accompanyingdrawings;Figure 1' is a sideelevation of a machine embodying my improvements; Fig. 2 isa front view, artly in section, of the'lower portion of the machine; Fig. 3 is an enlarged end view showing the mold cylinder and support therefor, and one of the. suction cu't-ofl? plates and vacuum breaker pipe; Fig. 4 is a fragmentary view pa'rtly in elevation, of featuresshown in Fig. 35- Fig. 5 is an edge view of one of the suction cut-ofi' plates;

breaker pipes; and Fig. 7 is a detail view showing the locking devices forthe formlug-roll carrier.

' ,1 represents'a tank or casing, in which a reticulated mold roll or shell 2 and 'a' similarly constructed but smaller couch roll or shell 3 are located.- The ends of thereticulatedjmold shell or roll are provided with open heads 4 havinghubs for the accom' Fig. 6 is a detail view of one of the vacuum modation of a" shaft 6, and adjacent to said open {heads ofthe mold shell or roll, fixed deckle.ring's 7 are located in thewalls of the casing. Boxes Sure provided for the journals of the shaft 6' and these boxes are givotally mounted in yokes 9,the latter ing loosely mounted upon levers 10. Each and provided at its.othcr end with a laterally projecting arm 1 11, with which a lever 10 is pivotally supported at one end top of the easing and is provid d. with arr-,8 adjusting nut 14. The mold shell or roll is" thus-yieldingly supported by the levers f0 and the supporting rods 13 and springs J2 are-(by reason of the lateral arms 11 on said levers) located outwardly beyond the decide.

rings.

The mold roll or shell 2 is provided C6117 trally with a core 15 which is of double conical shape 'in longitudinal sectionthat to say,- in the shape of two hollow cones placed base to -base'the portion outside ofv said central contact section being divided into compartments 16 by a seriesof radial partitions 17 which terminate in contact with the inner faceof the perforated or reticulateliperiphery of the mold. The cen-Z tra'l part of the internal. double cone is provided with a peri heral rib 18 for supportin'gthe reticulate circumferential covering of the mold roll or shell.

The couch roll 3 is constructed the same as above described except that it is smaller, and is mounted in fixed bearings.

' Air chambers 19-20 are located end of the vator cusing so as to communicute with thecnds of the mold and couch rolls 2 and 3 respectively, and pipes 21 conat each n'ect these air chambers with-any suitable exhaust device. Valves 22-423 are located Ill-the bottoms of the air chambers 1.92 0.

At each end of the machine, bell-crank levers 24 and 25 are located and connected,

by means of links 26-27 with the respective valves 22-23. One arm (ifeach bellcrank is located. outside of the casing and .these arms of the be'll cranks (at each end of tlie'machine) are connected, by means of rods 28-29, with armsBO secured to a shaft 31 which extends from one end of the machine to the other. Aval-ve operating lever whereby, the valves can be held'in any dc sired position.

These snctiop cut-oft plates are normally heldin fixed positions by lIJGZLDS Of pipes 36-37 which pass through i :said plates near the upper ends of the latter, -sa id' pipes extending outwardly 'from the plates"3 4- 35 and through-the. walls of ured. 'The. oi1ter ends of the pipes fill-37 the,cas ing, to which they are adjustably scinay b'e. provi ded with caps 38, but when Qthese eaps arememoved, said pipes 1:'-"rforni' another functioin'as presently explained.

of the layer of pulpon the mold roll approaches the couch roll, the suction in the compartments under the advancing layer of pulp will be cut-oil by the plates 3% and couch roll. In like manner, the pnlpwill be delivered by the-couch roll, to a forming roll over the same.

It sometimes becomes desirable, when weak pulp 18 being operated, that the artial vacuum within the reticulated roll s all be positively broken near the juncture ot-zthe mold and couchrolls' and near the juncture of the latter witlt'lhe forming roll, in order that the layer of pulp shall lac-more readily released. To accomplish sn'ch'breaking of the vacuum, the pipes 3 6-'--37 arc-employed and when thus used, the caps 38 will, of course he removed. I 5

Should the operator now depress either the hand lever 60 or I the foot lever 62, the spring rod or bar 61 will be moved downwardly and the tooth 63, bell-crank 58', will pin 56 to be withdrawn to release the form- 1ngroll carrier. -After a. tube shall have been completed on one of the forming rolls and the carrier released, the oierator will turn said carrier to more the orming roll with the com leted tube, away from the couch roll and to more an emptyforming ,3 w r l'Oll into position over the couch roll. This operation can be eti'ected without stopping It will be observed that the.

the machine. shaft 48 which constitutes the axis of the forming roll carrier, isnot in vertical alinement with the axis of the couch rollf When 2 0 the carrier is turned'to move a. completed tube away from. the couch roll the forming roll on which said tube has been wound, will also descend by reason of the descent of tlie foi'ni-ing roll carrier, and consequently the i pulp tube on said forming-roll will continue to have contact with the couch roll and will remove the pulp froina'portion of the active surface of the couch rollbefore entirely leaving the latter. \Vhen the carrier shall so have been turned snfliciently to bring another forming roll into position .over the couch roll, the latter will not have turned far enoughto cause a layer of ulp to be fully wound, and hence .thepn p will be '35" properly transferred from the couch 'roll to g the new forming rolhand necessity for stoppingthc machine while the forming rolls are being shifted, will be avoided.

In order to properly counterweight the. .0 forming roll carrier and the forming rolls.

therein, and permit a forming roll to rise during the accumulation of pulp thereon, the appliances now to be described will be employed. l

Levers 65 are pivotallymounted near the of the mountings of the shaft 48 and the short arms 6 of said levers (which project under the shaft 48) are r'ovided with small 50 rollers SLto engage said shaft. The long arms of the levers are provided with weights 68. The short arms 66 of said levers 'pro ect beyond the standards and have pivotally attached to their free'ends, the upper ends of Vertical rods 69. The rods 69 are rovided at their lower ends with rack bars 0 passing through guide brackets 71 A shaft 72 is mounted in the brackets 71 and carries pinions 73 to mesh with the 'r-ack 30 bars 70. Drums 74 are also secured to the shaft 72 and on these drums, cables 75 are wound and provided'at their free ends with depending weights 7 6. By the provision ot the weights 68 and 76 connected with the 65 forming roll carrier as aboi'c described, said carrier and the forming rolls will be counterweightedin a manner to insure the accurate and easy operation'ot' the .tube forming mechanism.
