Application iiled October 29, 1921;

To all whom t may concern Be it. known that We, JOHN lll. Vnnnnn and llnnnnnrcii lll. Lonnrne, residents of llforcester, Massachusetts, and citizens 0i have invented new and useful Improvements in Paper-Making Machines, which invention is fully set forth in the following speciiication.

This invention relates to the Fourdrinier or Wire part of paper machines. ln niany mills. in the Inalring of news print paper (which may be of low grade or quality because it is only ior temporary use) it is common practice to dispense entirely with shaking of the Wire. But lor higher grades olf' paper the usual lateral shaking ci the Wire is still resorted to by the use of structures in which the shaking or vibration is imparted to a, longl and heavy itraine, to the breast roll, numerous Wire supporting table rolls, guide rolls and other parts all mounted on said iranie, and to the Wire itself running; over said rolls, said shaken parte gregating great mass and Weight The repeated starting and stopping;` oif such inass and Weight of parts, ence for each vibration, involves great strain. requires additional Weight to attain requisite strength oi structure, occasions considerable Wear and deterioration o i" parts with resulting` increase in cost oi maintenance or upkeep. and also occasions complications @i parte and structure addingl to the time and ei'lort required in replacements oi? the vvire7 each Wire lasting only i'roi'n one to three Weeks in a machine running regularly at normal capacity. ln such structures the iull length oif the lateral 'l king' stroke imparted to the end oi' the rame at which the breast roll` carried, grraiflually diminishes in amplitude toward the other end or the traine which pr, turns about or pivots on a rertii i While the inl1 force and width oi' the shaltinf Stroke at and in the Vvicinity of the breast roll is desirable and necessary to thoroughly interweave the fibers ot the pulp mixture delivered on to the Wire, the attenuated diminution in amplitude of stroke until it becomes practically nil at the far end Serial No. 511,340.

of the long vibrating trame and long series of table rolls carried thereby, acts to a material extent to straighten out the libers of the sheet and to thus undo the previously attained intervveaving of said fibers. ln other Words, appr ximately as goed and possibly better paper formation may be attained by shortening the shaking length oi Wire.

rlhe primary object or' this invention is to provide a machine in Which a relatively short length of Jhe wire at the receiving end thereof Will be shaken or laterally vibrated to avoid attenuated gradual diminution op." shalt@ or vibration elitenoing far down the wire from the receiving` end thereoif, and to accomplish this in a manner dispensing with large and Weight oi shakparts and eliminating strain and rapid to thus simplify' the mechanism and e ct a material. saving; not only in the initial cost thereoiFl but in expense o'f main-- tenance or upkeep olf appar tus.

The aforesaid and other objects and arl-- vantages which will beconie apparent ircni the detailed descr 'ion are accomplished by the structnre ci' 'tl s inventiony a preferred embodiment oi' which is illustrated in the dcconipanying drawings wherein-- Figa l and l"L are together a side elevation of the Fourdrinier ps t ci the machine;

Fig. 9 is a fragment-ary plan view, similar to the lett hand end or" Fig. 8, but showing a modified structure in Which none of the table rolls are to be vibrated the shake of the Wire resulting from vibration of the breast roll only.

Referring first to Figs. 'l to 6 'inclusive-to provide for changing the elevation ot the Fourdrinier Wire at the receivingI end thereof and to tliereby Aattain the desired piteh or inclination oit' said wire 'from its` receiving toward its delivery end, We, employ a traine carrying most ot the rolls on which the Wire runs, said -Atrarne being;r vertically adjustable at its end toward the tloiv box and supported at its other end 'to turn on a horizontal axis or pivots. Said trame is made up of the folio-.ving partsat the end thereot next tothe ilovv boi; there is a 'transversely positioned beam il -o't elongated U-shape lhaving1 at its opposite ends respectively upstanding l2 and 13 of hollow construction. lil is a longitudinally extending -top rail at one side oit the frame secured at one end by bolts l5 to the top of arm 1 3 of beam ll and cured at its other end by a bolt 16 to a plate 17 which fits on a block 18. said block depending between tivo ears lil and l?) at the upper end of a supporting post or standard 20 and said ears and block heine; traversed by a horizontal pivot pin Q11., such structure being;` similar to that illustrated in Figs. 6 and 7 olf Patent No. 1,1 ,366, dated Nov. 24, i914, to Mellinger, et al.

At one end bar Qdi is connected 'to the upright arm 13 of beam 11.1 through the intermedia y ot' an angle bracket Q5. An upwardly cuwedv arm 26 is rigidly bolted to 'the other end of bar 24- said arm at its upper end heine traversed by and pivoted on the beto, e: mentioned pivot pin 21 as shown in Fig'. e.

The seri this. rolls 32 are similarly suppori bearings carried by an angle plate Si' supported :troni rail 14: by braelets F38 and and by a similar angle plate suppor ed by similar brackets from the rail 2Q at the other side oit the machine. rllhe series or `group ot tale rolls 3l are supported. in bearings carried by angle hars t0 and lfl r peetively at opposite sides 'oli the machine. see` Figi'. `Since the series of table rolls 3l is to he sl alien the :ingle bar fl() is iliivotally sirported at one end troni rail l/lf by a bn liet Ifi-)4 and angle bar el likewise pivotaly supported at one end troni rail 22 luy a ybracket The supporting ot the other ends of anole bars al() :sind #ll `will be described iiresen v. 41:5 the breast roll which is supported in `a `iozinner admi i oli the impart/in ot shale ing' movement to it and its supporting bearings Without vibration oit the frame liereinliierliore described yor other part ot the main framework ot the machine. At each end ot breast roll l5 the shaft thereof rests in an. open sided bearing member /l-G os shown in Figs. l, 3 and 7. The bearing` mi acel of said mei'nber is gijrooved to reenlargeinents or ribs el? extending! 1d the projeo ne sliait end. whereby one; movement iniparted to either ot j members Will be transmitted st roll and through it to the other bearing member 4G.

A. fiat steel spring har 48, the right hand side et the machine, Fig. 2. is securely bolted at its upper end in a slot `oit a link e9 the beivg; pivoted by a pin 50 in a slot be- -llll ien tween ears 5]. (F ig. 7 on the underside of the bearing member 46; but it preferred said upper end of the spring may be rigidly secured to bearing member 46, for example, in the manner the upper end of the corresponding spring of the aforesaid Mellinger et al. patent is secured. Said spring 4S at its lower end is seated in an upwardly opening notch or slot 52 of a stirrup or bracket 53, Figs. l, 2 and 5, depending from and preferably cast integral with the upright arm 13 of the beam 1l. By such arrangement said bearing 46 is movably supported by the spring 48 with the flat surface 54, Fig. 7 thereof in engagement with a bearing plate 55, preferably of brass, which as shown in Fig. 5 may be detachably secured to the arm l2 by screws. The other bearing member 46 at the other side of the machine, at the lett in Fig. 2, is supported by similar means including a fiat steel spring 56, link member 57, pivot pin 58, a notch or slot 59 engaged by the lower end or" spring 56, said notch being formed in a stirrup or bracket depending from arm l2 of the beam ll. In this instance also a iiat face 54 of the bearing member 46 engages a brass plate detachably secured to the arm l2 and similaito the plate 55 hereinbefore described. The projecting end ot the pivot pin 58 is engaged by the end of a pitman or connecting rod 6l, Fig. 2, driven from any suitable source of power (not shown) to impart vibrating or shaking movement to the bearing member 46 at the left of Fig. 2 and thence to the breast roll 45 and through it to bearing member 46 at the other side ot the machine. An arm 62, secured at one end to the bearing member 46 at the lett in Fig. 2 by bolts 63, bends rearward to a p ivotal bolt connection at G4 to the forward end of the hereinbeiiore described angle bar 4l, said arm thus serving both to support said end of bar 4l and to impart vibrating or shaking movement thereto around the pivotal support at the rear end of said bar. An arm at the right of Fig. 2, similar to 62, secured by bolts 66 to the bearing member 46, also bends rearward to a pivotal bolt connection at 67 to the 'Forward end of angle bar 40 hereinbe fore described, said arm 65 thus serving both to support said end oil.L bar 40 andto impart vibrating or shaking movement thereto around the pivotal supj'iorting connection at the rear end thereof. Such lateral vibration or shaking of the bars 4() and 4l, sinn'lltanc ously with the similar movement ot' the breast roll 45, also imparts endwise shaking movement to the series ot table rolls il een tending between and supported by said bars.

To prevent vibration of the hereinbeifore described :traine incident to the aforesaid. shaking of the breast roll and the series oit table rolls 3l. two 'vertically depending

plates

70, 70 are secured by bolts to the un' derside of the U-beam 1l, near opposite ends thereof respectively, each plate 70 fitting closely and slidable between the oppositely positioned vertical surfaces of a pair of brackets 7l bolted to a transverse base beam 72, Fig. 2. Thus while the plates 70 per mit vertical. movement or adjustment of the breast roll end of the 'frame in changing the pitch of said frame and of the Fourdrinier wire carried by the rolls thereof, said plates 70 rigidly secure said frame against lateral vibration incident to the shaking of the breast roll and other parts.

73, 74, Fig. l and Fig l;L are carrying rolls for the Fourdrinier wire suitably mounted through the intermediary of suitable bearings (not shown) at opposite ends of said rolls, on the bars 24 at opposite sides of the machine, or on the iframe ot which said bars constitute parts. 76, 77 and 78, Fig. lZL are other carrying rolls for the wire suitably supported and journaled in well known manner not illustrated. 79 is the lower couch roll also suitably supported and journaled in well known manner notillustrated and over which the wire runs at one end of its path of travel. 8O is the endless Fourdrinier or making wire running over the aforesaid rolls and passing at one end around the breast roll 45, the pull on said wire serving to hold the projecting ends ci the shaft or axle of the breast roll firmly seated in the open sided bearing recesses of the two bearing` members 46, 4G, respectively.

S1, Sl are two save-all receptacles each extending` across the machine beneath the table rolls and wire thereon and resting at opposite ends on rollers S2 journaled in supports S3 secured to bar 24 and to the corresponding bar at the other sideof the machine. Suitably supported roots 84, each resting at one edge on an edge ot one of the save-all receptacles 8l, serve the usual pun pose oil draining into said receptacles liquid falling thereon from the pulp mixture delivered on to the wire. These save-all receptacles and roots being thus mounted upon and carried by the frame participate in any vertical adjustment oi said frame in changing the pitch oi the wire The saveall receptacles and roots may however be supported independently ot the trame so as not to participate in adjust-ments thereof.

Vertical. adjustment of the breast roll end of the aforesaid frame is effected by the 'ich lowing means z--The ujiright arms l2 and i3 of the U-beain ll are each formed with downwardly opening socket 85 having a bearing block 86 of hardened metal secured in the upper end thereof and provided with a downward opening seinispherical bearing recess or socket. A tubular supporting member 87 extends upwardly into said. socket 85 and has secured to its upper closed vend a bearing block 88 ot hardened metal l tl having4 an upwardly projecting semispherical knob engaging the corresponding socket ol' block 80, as best shown in Figjl. Art its lower end the member 87 rests and is held by the weight ot parts ina seat 89, 4, or' a casing,` toi-ined in two parts 90 and 91 detachably held together by bolts 92 and serving to enclose antiiriction ball bearings and gears about to be described. An upright support, post, or bar 95 is horizontally pivoted at its lower end at 96 in a base block 97 rigidly secured to the floor or other foundation on which the machine mounted. The upper screw-threaded end of har 95 extends upward through the two part casing;` -91 and 'nto the tubular member 87, as best shown in Figs. 1 and 4. A worm gear 98, housed within the two part casing):- 90--91.y has an elongated interior screw-threaded hub through which the screw-threaded portion ol? bar engages. Three sets of antifriction or ball bearings, shown in 4, are interposed between the worm gear 98 and its two part enclosing casing,` to take the vertical and side stresses ot' the supported load and to provide ttor tree and easy rotation of said worm gear in raising or lowering` the trame and parts carried thereby to change the pitch of the wire. The balls 100 of the lowermost set oi: bearings work between a ring 101 surrounding the lower end ot the hub oit' the worm gear and a ring 102 secured within the casing member 91. An annular plate 103 is secured by screws to the underside o1 casing 91 and carries a packing` ring` 104 of leather or other suitable material closely itting around the peripheral surface o1 the lower extremity oit the hub on the worm wheel to prevent leakage of lubricant. The balls 105 oi the next set oit ball hearings work between a ringw 106 surroundingthe part of the hub projecting upward from the top side of the worm gear and a ring 107 secured in the upper casing member 90. The balls 108 of the uppermost set ot ball bear ings, which set takes the stress of the vertical load, work between a ring 109, located .at the top of casing` member 90 and surrounding the upper end of the hub of worin wheel 98, and a ring 110 also surrounding, said upper end or" the hub and separated from the before mentioned ring 106 by an interposed ring` 111. A worm 112, also housed within the-two part casing 90-91, engages the worm wheel 98 and is secured to a horizontal shaft 113 which has bearings in said two part casing;v vat opposite sides of said worin. Said shaft 113 extends all the way across the machine and kcarries at each end thereof a hand wheel 114 as best shown in Fig. 2.

It is to be understood that the tubular support member 87, the two part casingu .904491, the upright .piroted screw-threaded cated at the other side oit the machine in connection with Jhe upright arm 12 and its downwardly opening,- socket, the: shai't 1.13 being common to the two worms 112, 112 at opposite sides ot the machine. AS will thus be apparent, rotation of said shaft by gripping; and turning .either ot its hand wheels 114, acting through the two worms 112, 112, on said shalt will rotate the two worin wheels in engaementv with the twoscre-w-threaded support bars 951 at opposite sides ot the machine and thereby raise or lower the supporting traine iiinitornily at both sides oi? the machine according; to the direction in which the hand wheel 114 is turned.

Referring particularly to Figs. 1 and 1a, is a deckle strap running over a deckle wheel 121 at one end, Fig. 1, and deckle pulley 1.22 at its other end, Fig. 1, and passing through deckle wash trough 128 supported on a deckle trame 124 shown as supported from the side rail 14 by

brackets

125, 125, all these parts being or well known construction and duplicated at opposite sides of the machine.

Flow box 130, shown in Fig., 1, may be of any well known suitable construction, with a delivery opening` at its front side the lower edge ot which is indicated at 181 by dotted line, and provided with a suitable apron 182 adapted to be vertically adjusted to the desired position relative to the elevation of the wire and to the delivery opening` of the vHow box by means o a screw 133 adapted to be rotated by hand wheel 18s. through beveled `gears and 136, Fig. l. Fig. 8 illustrates a modilied structure in which the elevation of the apron 182 is auto` matic-ally adjusted to follow changes in the elevation of the receiving` end ot the wire, this being accomplished through the tollowingj connections which are preferably duplicated at opposite sides of the machine, to wit--140 is an arm secured to, or it may be cast integral with, the Stirrup member 53 and extending` therefrom. toward the llow box. A link 141 pir'otally connected at its lower end to said arm 140 and at its upper end to a lun; 142 secureifl to the apron 182. lt iollo ws that any up or dmvn niofvcment imparted to the traine carrying the wire and rolls over which it runs will be transmitted through said connections to the apron 132.

Fig. 9 illustrates a modified structure in which the series or table rolls 81, instead of being` shaken or vibrated along' with the breast roll 45 as in the structure illustrated in the other figur-es of the drawings, are not shaken, 'and are moved endwise, vit Aat all,

only in. so liar as the Yfreedom of their bearings permit and such movement is imparted thereto by the wire resting thereon. As shown in said Fig. 9, there is no shake transmitting arm such as G2 connecting one end or the angle bar to the bearing 46, but on the contrary said bar is rigidly secured to and supported at both ends from the rail 22 by the brackets 43, t3 shown in dotted lines. The angle bar at the other side of the machine correspending` to il is similarly arranged and rigidly connected at both ends to the rail at that side of the machine corresponding to 22.
