Application iiled January 18, 1915. Serial N o. 2,051.

To all whom t may concern:

Be it known that we, ARTHUR J. HoDGE and HENRY B. RUeoLEs, citizens of the United States of America, residing at Pasadena, in the county of Los Angeles and State of Califbrnia, have invented certain new and useful Improvements in pulp gathering, transferring, squeezlng, compressing, forming, and dryin devices or regular and irregular shaped rums or cylinders, of which the following is a specification.

This invention has relation to certain new and useful improvements in pulp gathering, transferring, squeezing, compressing, forming and drying devices for regular and irregular shaped drums or c linders and has for its primary object, t e provision of mechanism of improved construction and operation which may be readily substituted for the primary pulp compressing and squeezing mechanism and also the secondary pulp compressing and shaping mechanism of the machine disclosed in our first or original application, Serial Number 741, filed Jan. 6, 1915.

The invention has for another object, to provide a device of this character which may be employed for pulp gathering and transferring alone or for pulp gathering, transferring, squeezing, compressing and forming or for pulp gathering, transferring, squeezing, compressing, formlng and dryin as desired, and employed in connection wit any other part or parts of the machine disclosed in our above referred to first or original application or of any other analogous machine.

Another object of the invention resides' in the provision of a `device of the above stated character which will be of such construction and operation that when it is desired to employ the same for gathering and transferring only, it may be substituted for the primary compressor and squeezer bars of our original machine and the operating mechanism for said bars, withoutdisturbing the secondary compressor and shaping bars of said machine, or the operating mechanism for the last mentioned bars.`

A further object of the invention resides in the provision of a device of the character set forth which will be especially adapted for use in connection with forms or former-sections movable spirally through a pulp containing tank, the device being constructed and mounted in such manner as to' be operated by the spiral movement of the forms or former-sectlons to gather pul from the tank and transfer the same to said forms or former-sections and compress and dry .the pulp upon the outer' face of said forms or former-sections and'atthe same time squeeze all surplus liquid from the' `the pulp While the latter is being compressed and shaped upon said forms or former sections to produce the article or articles of the desired configuration and size.

A still further object of the invention resldes -in the provision of a device of this character in which one or more tension belts may be employed, as the occasion may require, to gather and transfer the pulp to the moving forms or former-sections and compress and dry the pulp around said forms or former sections, as the latter move longitudinally through the pulp containing tank.

Still another object of the invention lies in the provision of a plurality of tension belts engaged spirally around the connected forms or former-sections t gather, transfer, squeeze, compress, shape and dry the pulp around the forms or former-sections as desired, the belts being arranged one above the other with their adjacent edges close together to limit the amount of pulp reaching iis the forms or former-sections after the first or primary compressing and squeezing operation, each belt being arranged or coiled around the forms or former-sections in such F 2 is a side elevation at substantially right angles to l? ig. 1, with the pulp containing tank in section;

Fig. 3 is a top plan View;

is a View similar to Fig. 3, with the upper or secondary tension belt removed to show more clearly the lower or primary tension belt;

F ig. 5 is a detail section on the plane of line 5-5 of Fig. 1; and y ig. 6 is a detail section on the plane of line 6 6 of Fig. 5.

Referring more particularly to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 designates the pulp containing tank which may be supported in elevated position by any suitable means,` not shown, and receives a continuous supply of pulp'from a feed pipe 3 having its discharge end directed toward the open upper end of said pulp containing tank 1.

Extending longitudinally through the pulp containing tank 1 is the stationary shaft 4 ofthe machine, the bottom of the tank being provided with an opening 5, through which the stationary shaft 4 eX- tends.

Around and spaced from the stationary shaft 4 and secured in the, opening 5 is the upwardly dared pulp receiving and directing receptacle 6, which is preferably of the form shown in our original application and has its depending downwardly flared lower end projecting through said opening 5,'

while its outwardly directed annular flange 7 extends from the narrow portion of said pulp receiving and directing receptacle 6 and is secured in any suitable manner upon the upper face of said bottom of the pulp containing tank l.

Formed upon a portion of the stationary shaft 4 below the pulp containing tank l, is a spirally extended feed and guide thread 8 for feeding and guiding upwardly inA a spiral direction the forms of former-sections A, it being understood that the forms or former-sections A are each rovided with suitable interior central gui e nuts 9 for engagement with and movement over the feed and guide thread 8, and that said forms or former-sections A may be of the construction shown in the drawings and also shown and specifically described in our co-pending application Serial Number 741, filed Jan.

' 6, 1915, or of any other preferred or well known construction. The outer cylindrical or body portion of each form or formersection A should, however, be perforated and have a screen 20 mounted upon its outer` face and secured in position by the hoop sections 21, which serve to form chines and head channels of barrels and the like, or by any other suitable means.

The forms or former-sections A may be placed in position around the stationary shaft 4, below the feed and guide thread d, in consecutive order and raised and rotated y upon said stationary shaft 4 until they automatically lock together and the guide nut S) of the uppermost form or former-section A. catches upon the feed and guido thread S. Then, as each additional form or `formersection A is placed in position upon the stationary shaft 4, it is simply necessary to raise or elevate the same until it engages and locks with the form or former-section A immediately above the same, when it will be carried by the last mentioned form or former-section A and all above and locked with the latter, in an upward spiral direction around said stationary shaft 4 and through the pulp containing tank 1, after passing through the receptacle 6, to collect pulp from the receptacle 6, and tank 1.`

Any suitable means, not shown, may be employed for rotating the connected and locked together forms of former-sections A over the feed and guide thread 8, and thereby causing said forms or former-sections A to travel in an upward and spiral direction through the pulp containing tank 1. There fore, the rotating means will not be spe ciically described or shown and further detailed description of the construction and operation of the forms or former-sections A in this application, is believed to be unnecessary, as these parts do not constitute the most important parts of the present invention.

The present invention, however, resides principally in the provision ofthe primary and secondary tenslon belts C and D, respectively, preferably formed of a porous elastic materiall and mounted to operate in such 105 manner as to gather pulp from the tank and transfer the same tothe form or formersections A and compress, squeeze, shape and dry the pulp upon said form or former-sections A during an upward spiral movement 110 of the latter through the pulp containing tank 1.

The primary or lower tension belt C is passed downwardly around the idler 22 mounted upon the inclined stub shaft 23 115 which is carried by the inclined portion 24 of the pivoted arm 25 which has its lower extremity mounted upon the pivotl pin 26 extended transversely through the bearing ears 27 of the plate 28 which is mounted upon 120 the upper face'of the bottom of the tank 1,'

vit being understood that the lower extremity of the pivoted arm 25 is engaged between said ears 27. From the inclined portion 24,

the pivoted arm 25 is extended upwardly 125 and tapered to the point at which it cony nects with the perforated head of said arm 25, within which is secured one end of the tension spring 30, which has its opposite end 31 threaded and engaged through the 130 wall of the tank 1 adjacent the top thereof, with a regulating nut 32 mounted upon said threaded end 31 outwardly of the tank 1, whereby the tension of the spring 3Q may be readily regulated to vary and control the tension of the primary or lower tension belt C, the arm 25 swinging upon its lower extremity to the proper incline or angle with respect to the bottom and -side walls of the tankA l.

After beingr passed in this direction around the idler 22, the primary or lower tension belt C is extended inwardly and given a quarter turn and passed around the perforated periphery of the guide wheel 33 mounted upon the slightly outwardly inclined stub shaft 34. The primary or lower tension belt C is then coiled spirally around the forms or former-sections A and the pulp gathered upon the same from the receptacle 6 an'd the space immediately above the same. The entire primary or lower tension belt C is positioned a short distance above the top of the receptacle 6 and after being coiled around the forms or former-sectionsl A and the pulp upon the same, said primary or lower tension belt C is returned to the idler 22, being given a quarter turn in the reverse direction, the idler 22 being a suiicient distance from the forms or former-sections A and the guide wheel 33 to permit of a quarter turning of the primary or lower tension'belt C without danger of the same riding olf of the idler 22.

The primary or lower tension belt C is porous and also elastic and as said primary or lower tension belt C passes around the guide wheel. 33, pulp is gathered upon the outer face of said belt and transferred to the outer faces of the screens 20 of the forms or former-sectionsl A and this pulp together with the pulp gathered upon the screens 20 before the latter reach the coiled portion of the primary or lower tension belt C, is compressed upon said screens 20 as the forms of former-sections A move upwardly and spirally within the coiled'portion of the primary or lower tension belt C,by the latter. It will be readily seen that, owing to the elasticity of the primary lower tension belt C, this belt will automatically adjust itself to the thickness of the pulp Wall around the forms or former-sections A and the movement of the latter will cause operation of the primary or lower tension belt C in the proper direction and at the proper rate of speed, the surplus liquid from the pulp being compressed and shaped upon Vthe screens 20, passing either to the interior of the forms or former-sections A or outwardly through the coiled portion of said primary or lower tension belt C.

Owing to the difference in diameter of the forms or former-sections A and the small guide wheel 33, it will be readily seen,

especially by referring to Fig. 4 of thesaid moving forms or former-sections A,

so that the pulp. gathered by sa-id primary or lower tension belt C- as it passes around the small guide wheel 33, may be readily transferred to the screens 2O to be tightly compressed around the same.

Liquid from the pulp gathered upon the portion of the primary or lower tension belt C passing around said small guide wheel 33, may .-pass freely through said belt C and through the perforated periphery of said small guide wheel 33 to the interior of the latter, from whence it may escape by way of the liquid discharge pipe 35 positioned over an opening 36 in the bottom of the tank 1 and having a flanged lower end 37 secured upon the upper face of said bottom around said opening 36. It will be understood that the stub shaft 34 of the small guide wheel 33 is secured in a suitable bearing 38 formed at the upper end of said water discharge pipe 35 and that said wheel 33 rotates freely,

upon said stub shaft 34 andthe upper end of said water discharge pipe 35 and also upon the shoe 39 which is of substantially se1ni circular form and projects upwardly from the extension plate 40 carried by the upper end of said liquid discharge pipe 35. The shoe 39 is inwardly of the perforated periphery of said wheel 33 and said shoe 39 and extension plate 40 are positioned so as to permit the shoe 39 to cover the openings in the periphery of the wheel 33 between the points at which the primary or lower tension belt C engages and leaves said guide wheel 33, thereby making it impossible for pulp to gather upon this portion of the wheel or liquid to pass through the same.

The liquid passing through the remainder of the Whe 33 andthe primary or lower tension belt C engaged around the same as the pulp gathers upon said belt C, will cause a suction and thereb attract the pulp to the belt C at this point, as will lte readily understood by referring to Fig. 4 of the drawings.

The secondary or upper tension belt D is engaged around the upper guide wheel 41 mounted upon the stub axle 42 projecting laterally from the inwardly bent upper end or angle of the angle arm 43 which has its depending end or angle secured to the inner face of the pulp containing tank 1 adjacent the upper end thereof in any suitable manner, as shown .at 44. The belt D is then brought downwardly and engaged around the lower guide wheel 45, which is mounted upon the stub axle 47 projecting laterally from the inner end of the arm 48 which has its outer end bent at an angle and secured to the inner face of the pulp containing tank 1, preferably below the gathering or pulp level line whereby the guide wheel i5 will be supported below the gathering or pulp level line B. rlhe secured and bent end of the arm 48 is clearly shown in Fi 3 of the drawings and indicated by the re erence character 49.

After being passed around the lower guide wheel 45, the tension belt D is given a quarter turn and engaged around the large guide wheel 50 which is positioned in a substantially horizontal plane and mounted upon the upstanding stub shaft 5l which is positioned in a practically vertical plane so that the large guide wheel 50 has its edge toward the stationary shaft 4,; tilted downwardly slightly, the purpose of which will presently appear. i

After being extended around the large guide wheel 50, the tension belt D is coiled around the pulp wall upon the outer face of the screens 20, for seine distance above the gathering or pulp line E and above the upper edge of the pulp containing vtanlr l and then extended outwardly from the pul wall and given a quarter turn before `1t again returns to the upper guide wheel 41, previously mentioned. This tension belt B serves as a secondary compressing and shaping belt to give the final compression to the pulp wall and shape the same around the screens 20. lt will be readily seen that as the large 'guide wheel 50 is only a short distance from the moving forms or formersections A, the belt D, as it travels from the large guide wheel 50 to the partially compressed and shaped pulp wall, will gather. additional pulp and transfer the saine to the pulp wall just above the last or uppermost coil of the primary tension belt C and the upward spiral movement of the connected forms or former-sections A will cause the tension belt D to move with the same. lt will also be evident that as the tension belts C and D are resilient, they will automatically adjust themselves to the cylindrical pulp wall as the saine decreases in diameter under the pressure of said belts C and D. The belts C and D maybe formed of any suitable material and applied in any manner desired and if preferred, the num ber of belts may be increased and addi tional belts positioned above the gathering or pulp line B to serve simply as tension or drying belts.

rlhe large guide wheel 50 rotates above the flared upper or enlarged end oit the liquid drain pipe 52 which has its lower end positioned over the drain opening 53 in the bottom of the pulp containing tanlr il and preferably in a portion et said bottom opposite the portion in which the opening 36 is lo- Leaalo cated. The drain pipe 52 has itsv lower end 54 turned outwardly to form av suitable sup- Mounted upon the upper end of the drainy pipe 52 within the large guide wheel 50 and serving to support the stub shaft 5l is the shoe 55 which has an upstanding flange of substantially semi-circular form. The periphery or the large guide wheel 50 is perforated, as clearly shown in Fig. 3 of the drawings and the shoe 55 is so positioned that all liquid from the pulp gathered by the upper tension belt D as the same passes around the large guide wheel 50, may readily pass through the openings in the periphery of said wheel 50 covered by the belt after said liquid has passed through said belt, after which the liquid readily pass downwardly in said liquid drain pipe 52 and escape iirorn the saine by way of the drain opening 53. The shoe 55, however, will prevent liquid from passing through the openings in the remaining portion of the periphery of large guide wheel ed, thereby preventing the pulp in the the pup containing tank l from gathering directly upon the periphery of the large guide wheel 50 and working under the belt D and thereby probably causing the same to ride on ofv the wheel 501. l

By referring to Figs. l and 2, it will be readily seen that the coils of the primary tension belt C decrease in size from tie lowermost to the uppermost coil, thereby causing each coil of the belt C to do its share of the work of compressing the pulp around the moving screens 20 and while we have shown a space between. the uppermost coil of the primary tension belt C and the lowermost coil of the secondary or upper tension belt D, these belts may be brought closer together, if desired. y

As we have placed arrows ony Figs. 3 and flof the drawings to indicate the directie#L in which the tension belts C and D trav-'1-` during operation ci the device and hace carefully and thoroughly described the ccnstruction and operation of the complete vice, it is believed .that this description i: gether with the drawings will serve to Alee the invention clear and a further descripv` tion or' the device is unnecessary.

While the preferred embodimentl of the invention has been shown and illustrated, it will be understood that minor changes in the details of construction and arrangemr of parte may be made within the scope the appended claims without departing from the spirit of the invention or sacritisiing any o the advantages of the same.
