Patented Sept. 24, 1 929 UNITED STATES PATENT OFFICE A HERMAN L. KUTTER, OF HAMILTON, OHIO, .A SSIGNOR TO THE BLACK-CLAWSON COM- PANY, F HAMILTON, OHIO, A CORPORATION OF OHIO PAPER-MAKING MACHINE Application filed August 2, 1926. Serial No. 126,544.
This invention relates to paper-making machinery of the type adapted for the formation of a web or continuous sheet of paper from paper stock, and more particularlyto that type of paper-making machinery in which an endless paper-making part, such for example as a Wire or a felt, is employed in carrying the paper or paper stock. I
One of the principal objects of the invention is to provide a construction of the machine, or an element thereof, which will permit the ready replacement of the endless paper-making part.
Another object is to provide, in a machine of the type referred to, a paper-making element which may be readily moved frontwise out of the path of the web of paper.
Still a further objectis the provision of a 20 machine so constructed that temporary parts and expedients maybe dispensed .with in moving-the paper-making element frontwise I rnents 24 and 23 to the breast roll. 21, the wire 1n lts return movement being'guided by suitout of the path of the web of paper.
Other and further objects of the invention will appear from the following description taken in connecton with the accompanying drawing, in which:
Fig. 1 is a front elevational view of a paper-making machine embodying the pres- 0 cut invention;
Fig. 2 is an enlarged front elevational view of one element of the machine illustrated in Fig. 1, said element being the suction box frame, part thereof being broken away to ill 5 lustrate a detail of construction;
Fig. 3 is a vertical sectional view line 3--3 of Fig. 2; and
Fig. 4 is a view corresponding to Fig. 3 showing another position of the parts. 0 The present invention is herein described on the and illustrated in connection with a papermaking machine of the Fourdrinier type, al-
though it will be understood that the invention is susceptible of application in connec- 5 tion with other paper-making machinery such as press machines, and that the e'rnbodi ment in connection with a machine of the Fourdrinier type is for the purpose of illustration only.
0 Referring to Figs. 1 and 2; 20 denotes an endless paper-making part or wire, common ly known as a Fourdrlnler, which passes over a breast roll 21 at the inlet end of the machine arrangement of the paper-makingelements 21, 22, 23 and 24, as well astheir functions, are well-understood in the art and these parts neednot therefore be described in detail. During normal operation the paper-makmg part or Wire 20 isadapted' to receive paper stock from the flow box 30, after which the wire passes over the table rolls of element 23, thence over the suction boxes of element 24 and finally around the couch roll 22, after which the wire returns underneath the eleable rolls 31 as'illustra-ted in Fig. 1. The
sheet or web of paper formed upon the papermaking part or wire 20 leaves the wire 20 as the latter passes around the couch roll and passes to a press or other paper-making ma chine, all vas well understood in the art.
' these shut-down periods are not o ly frequent-but are often of considerable uration, the loss of production or output resulting therefrom represents a substantial loss. 1
The present invention contemplates reducing such loss of production or output resulting from shut-down during replacement of the endless paper-making part or wire, by so constructing and arranging the paper-making elements cooperating with the endless paper-making part that such paper-making elements may be readily and quickly with- The endless paper-making part of the wire drawn out of the path of the endless wire whereby to permit quick replacement of the I element 23, this element is provided adjacent each end with carriage and supporting means by which the element is supported from the floor. Such carriage and supporting means 1 comprises front carriages 35 adjacent each end; of the paper-making element and corresponding rear carriages 36, which carriages may be connected respectively with the front and rear side rails 37 and 38 forming part of the framework of the paper-making element 23, and upon which side rails the table rolls .25 are mounted. i
The front carriage is of such height as to rest directly upon the ground or foundation, and to move or roll thereover in a forward direction. For the purpose of facilitating movement of the element over the ground or foundation, the latter may be provided with suitable grooved track means 40 and the carriage may be provided with front flanged rollers 41 and 42 and a; rear roller 43, the rear roller being mounted in an elongated rearwardly extending arm 44 of the front carriage. Preferably the track 40 and the flange of the flanged wheel 42 are provided with cooperating geared teeth 45 and 46 respectively,-whereby the carriage means may be positively moved over the track means. A common drive shaft, 50 is mounted longitudi- Jnally of thepaper-making element 23 and has a driving connection at each end through driving gears 51 and 52 with gear 42. Operation of the driving shaft 50 by any suitable means either manual or otherwise, serves to move the carriages upon the track means rapidly and with certainty and in such manner as to prevent binding or other inconveniences resulting from possible unequal movement of opposite ends of the paper-making element.
During normal operation of the papermaking machine the carriage and supporting means are in the position illustrated in Fig. 3, the front carriage 35 resting on the ground and the rear carriage 36 being supported through roller 55 upon rail 56 which rests at opposite ends upon front and rear pedestals 57 and 58 respectively. The front pedestal 57 is provided with an opening 59 adapted to receive the arm 44 of the front carriage while the parts are in normal operating position, and locking means is provided at 60 to lock the front carriage to the front pedestal thereby retaining the paper-making element 23 in operating position. The side frames of the respective paper making elements 23. and 24 are cut away as at 89 to permit the units to be moved frontwise without interfering with the front pedestals 57 The front/end of the elevated track 56 normally formed upon the front pedestal 57, and the rear end of rail 56 is supported upon and guided by lower rollers and 66, and upper. roller 67, the lower rollers 65 and 66 having a geared, or driving connection with crank means 68 whereby rotation of the crank 68' will move the track 56 forwardly or backwardly to either of the full line positions illustrated in Figs. 3 and 4. During normal operation the elevated track 56 is locked against removal from the position illustrated in Fig. 3 by means of a locking bar 70 which is carried by the rear pedestal 58 but which may be removed to permit the elevated track to be withdrawn to the position shown in Fig. 4. A standard 71 havinga roller hearing at its upper end may be provided to the rear of the machine for supporting the rear extended end of the elevated track 56 when withdrawn from its normal position. It will be observed that the front carriages 35 are provided with base or foot portions of substantial area and of a construction which will permit the front carriages to carry the major part of the weight of the movable ele' ments 23 and 24. The rear carriages 36 which support only the rear portion of the movable elements may thus be of lighter construction than the front carriages and, likewise, the elevated tracks 40 for the carriages 36-may also be of comparatively light construction.
While the present invention is herein illustrated as applied only to the paper-making elements 23and 24, it should be understood that it is not limited in its application to rests upon a shoulder or ledge 62.
these elements but may be applied to other 1 elements of the paper-making machine, and
that the number of carriage means employed in connection with any single paper-making element may be more or less than the number illustrated.
In the operation of the particular paper- 6 making machine illustrated the removal or replacement of the endless paper-making element or wire 20 may be accomplished as follows :The breast roll 21 is removed from its normal position and suspended from the table-roll frame or element 23 in the position indicated in dotted lines at 75, any suitable means (not shown) being employed for suspending the breast roll in the position 75 so that the breast roll is carried forwardly with the element 23. The guide roll 78 may also be suspended from the other end of the element 23 in the same manner as the breast roll,
dandy roll may be readily removed in the as is also the reardandy-roll bearing frame 80.
The old endless wire is now removed and the I table-roll element 23 as well as the suction-box element 24 are rolled forwardly upon their respective tracks to the position illustrated in Fig. 4, these elements being then out of the path of the wire and of the web of paper. The removal of the old wire is accomplished in any convenient manner either before or. after moving the elements 23 and 24. forwardly. After the elements 23 and 24 have been moved forwardly, the elevated tracks 56 are moved rearwardly to the full line posi-- tion shown in Fig. 4 so as to provide a clear path or opening for the stringing of the new wire. During the time that the tracks 56 are in removed rearward position, the elements 23 and 2 1 are supported mainly upon their front carriages 35, but the rear carriages 36 serve also as supports through the rollers resting upon brackets 90 of the front pedestals 57.
To mount or stringthe new wire it is first placed around the couch roll 22 in the usual manner and then extended lengthwise of the paper-making machine, suitable means being provided for temporarily suspending the upper part of the wire above the'level of top surface of'the elements 23 and 24 so that when these elements are-moved rearwardly to their normal positions they will pass under. the upper part of the wire without causing damage thereto. After the removal of such temporary supports and the wire being in proper position on the suction boxes and the table rolls, the breast roll 21, and guide roll 78 may be returned to their normal operating positions and the wire tensioned for operation. The dandy roll 76 is replaced by a process which is the reverse of that described for its removal. I
From the for going it will be apparent that the present in ention provides means for rapidly 'and easily removing a paper-making element out of the line of an endless paper-making part or wire and greatly facilitates the removal or replacement ofsuch endless part or wire. Another advantage of the present invention is the fact that it is free from temporary parts or traps. The ele- 1 vated tracks 56 and other parts of the machine which are employed in the removalof the movable elements 23 and 24, are regular parts of the paper-making machine and are, during normal operation of the machine, in the. positionashown in Fig. 3, in which position the elevated tracks support the rear carriage and are locked in position.
\Vhile the form of apparatus scribed constitutes a preferred embodiment of the invention, it is to be understood that the invention is not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope of the invention which'is defined in the appended claims.
