Application filed August 29, 1910. Serial No. 579,380.

To all whom it may concern: j

Be it known that I, HERMAN L. Kn'r'rnn, a citizen of the United States, residing at Hamilton, Butler county, Ohio, have invented certain new and useful Improvements in Paper-Making Machines, of which the following is a specification.

This invention pertains to Fourdrinier paper-making machines and relates to improvements upon the construction of the Fourdrinier franie set forth in my United States Patent No. 654,651, of July 31st, 1900.

v The present improvements relate to the construction of the shake-rail trusses, to the construction of the shake-legs, to the mounting of the breast-yell, and to the construction of the breast-roll}truck-mechanism.

The invention will be readily understood from the following description taken in connection with the accompanying drawings in which Figure 1, is a front elevation of one of the shake-rail trusses: Fig. 2, a side elevation of the head portion of the same in conjunction with the shalte legand the breast-roll truck: Fig. 3, a vertical section of one of the shakelegs, in the plane of lines a of Figs. 4 and 5: Fig. 4, an elevation of one of the shake-legs as viewed from the right in Fig. 2: Fig. 5, .a side elevation of the breast-roll truckmechanism as viewed from the right in Fig. 2: Fig. ,6, a side view of the guide-pipe of the truck-mechanism. The various figures of the drawings involve a diversity of scales. As both sides of the machine are to be alike the showing and description will be general structure, under the free end of the' shake-rail: 4, the vertical pivot uniting the free end of the shake-rail to the shake-leg: 5, a strong bracket rigidly secured to the lower surface of the shake-rail at its free end, this bracket presenting a vertical surbracket: 7, a truss-bar disposed below the shake-rail and having its two ends rigidly,

secured to the vertical faces of the brackets 8, struts firmly connected with the shake-rail vibrating independently of each other.

The brackets at the ends of the shake-rail of-themselves endow the ends of the shakerail with very reat vertical stiffness and the truss-bar completes the trussing of the shakerail, the inner vertical members of the brackets forming vertical strut-members at the ends of the truss-bar. The struts 8, further stiffen the structure but are not needed on very short machines. The two brackets being locatcd'at the ends of the shake-bar close to the two supports of the bar, at pivots 2 and 4, effectually guard against deflection ofthc bar at points near its end. Inpractice I construct the bracket of steel castings, and I construct the truss bar'of cast iron of inverted channel section. The ends of the t-russ-' bar abut against the inwardly presenting faces of the brackets and are there solidly bolted, the ends of the truss-bar resting on hooks projecting inwardly from the flat inner faces of the brackets.

Proceeding with the drawings :11, indicates a pair of hearings in a common line length-wise of the machine, these bearings being secured to the mill floor below the free end of the shake-rail, the two bearings being, preferably, cast in one piece: 12, a vertical tube disposed between the two bearings and forming the lower member of the shakeleg: 13, bushings in the upper and lower ends of the tube: 1.4, trunnions projecting from the tube and journaled in the bearings, the tube projecting some distance below the bearings, and freely through suitable fioor-openings prouicled for them: 15, a screw mounted for vertical sliding motion in the tube, the periphery of the screw nicely fitting the bushings of the tube: 16, a nut threaded upon the screw and resting upon the upper end of the tube: 17, a worm-gear carried by the nut:

18, a worm-shaft journaled in suitable bearings projecting from the tube: 19, a worm carried by the worm-shaft and engaging the wormsgear: 20, a hand-wheel on'the wormshaft, by means of which the nut can be turned and the screw raised and lowered in the tube: 21, a 'spmcket-wheel'on the shaft to provide for .a chain transmitting the worm motion to the worm at the opposite shake-leg, as in my earlier patent: 22, a shake-leg head-casting having a large gap open, preferably, toward the tail end of-the shake-rail, this casting being bifurcated at its upper end to receive the pivot-bearing 9 of the shake-rail, the casting 22 forming the end. of the rigid breast roll frame extending across the machine: 23, a pair of separated fore and aft'downwardly open bearings in the base of the head-castingz-2a, trunnions projecting fore and aft from the head ,of the less than the distance between the two trunnion bearings a pivot engaging the pivot bearing 9 of the shake-rail and passing through the two side members of the'bi- ZO-furcated upper end of the head castingz 2ti,

a breast-rollbearing disposed in the gap of thehead-casting, this bearing comprising about half of the circleof the bearing'so as 5 breast-roll bearing: and 29, the general level of the mill floor.

Y The vibrating motion of the shake-rail is; I provided for by the oscillation of the tube and screw on tru-nnions 14 and by the rocking of the screw-head trunnions in the head casting, the head-casting being quite disconnected from the tube except through the medium of the-screw and its trunnions. The head ofthe screw, being less in width than the distance between trunnion bearings 23 permits of a trifle of endwise shifting of the head-casting on the screw trunnions as inciden't to the vibrating motion of the shakerail, pivots 4. and 25 connecting the shakemil with the head casting also providing for theslight changes in angular relationship between the shake-rail and head-casting.

The breast-roll journal ,has. its bearing forwardly and downwardly inbearing 26 so as to properly take the strain of the making wire, the bearing being held in this normal Working position by bolt 28. 1 When the breast roll is' to be removed, bolt 28 is first displaced, thus permitting the bearing to swing downwardly and forwardly on its pivot 27. But the relationship of pivot 27 to thesegmental bearing is such that when the bearing thus swings downwardly, sofas to brin the center of gravity of the breastroll un er the pivots 27, the hearings will screw and engaging the bearings 23, the 15 head of the screw being of a' width a trifle "no'attention need be given to still have such complete hooking engagement with the breast-roll journals as to hold the breast-roll suspended. Then, by lifting the roll and swinging the bearing forwardly and upwardly, the roll may be removed forwardly and downwardly so as to be withdrawn endwise from .the' machine. And, similarly, when the roll is to be placed in the machine, its journals are passed into the gaps in the head-castings and then the'bea r ingsare swung into hooking engagement below the journals, after which the bearings are pushed rearwardly and the bolts 28 applied. This system of temporarily supporting the breast-roll by bearings under free suspension is manifestly available in 1na-; chines gapped to the rear as well as to machines having the breast-roll frame-gapped forwardly as in the illustration."

It is to be particularly observed that the mounting of the breast-roll is such that all of the strains and strengths are in a single vertical line, that is to say, the axes of the axes of the breastroll journal and screw 15 and pivot 4 coincide and intersect I

trunnions

24 and 14,- A substantial adherv the breast-roll in the plane'of the general vertical axis of the shake-legsis found in practice to. give a very much better balance ence to the plan of disposing the axis of. I

and easy working of parts than when the 1 roll is some distance to the front or rear of the axis of the shake-legs.

If the breast-roll, instead-of being disposed substantially below pivot 25, be any material distance to the rear or to the front of the vertical plane of that pivot the effect, as the shake-rails are'raised and lowered, would be to slightly alter the relationship between the making-wire and the slices and thus disturb the delicate slice adjustment. In the present construction not only may the wire be raised and lowered while the machine is in'operation, but the slices by reason of such adjustment.

Proceeding with the drawings, and giving particular attention to Figs. 5 and 6r-- :30, indicates a'l'ow floor stand disposed below the rear one of thetwo shake-rails 1, this floor stand presenting upwardly a. pair of angular projections, the pair being arranged fore and aft of the machine: 31, a

rails and carry the breast-roll when being placed and removed: 34;, wooden bearing blocks in the trucks to receive the breastroll journals: 35, a third floor-stand temporarily placed at some distance from the front of the'machine and in line with the other floor stands: 36, a pair of track-rails similar to the other rails, supported by floor stands 31 and 37, a light pipe having a length somewhat greater than from the outside of floor-stands 30 to the outside of floor-stand 31: 38, notches cut in this pipe to freely engage over the intermediate portions of floor-stands 30 and 31: 39, an elbow projecting rigidly inward and, preferably, from the rear of the shake-leg head-casting 22: 40, a frame-bar to-be rigidly connected with the two elbows, this frame-bar and the two head-castings forming the breast-roll frame which is articulated to the shake-rails and to the leg screws as has'been described: 41, a' feather dis posed in the groove in tube 12 and bearing against a flattened side of screw 15, this feather being pressed to the screw by means of side-screws: 42, the bridge-piece connecting the two floor-bearings 11: and

43, a lug projecting from the inner side of 'tube 12 and adapted to engage the bridgepiece and liinit the inward rocking of the tube upon its trunnions.

The vibrating motion is to begotten to i the general structure by any suitable means, but my preference is to employ a lever projecting outwardly from the base of the rear shake-legs, as in my earlier patent. The length of the shake-legs, and the consequentv inclination or declination of the making-wire may be adjusted at both sides of the machine simultaneously by manipulating the mechanism giving rotation to the nuts 16, and without interrupting the ru'nning of the machine. This vertical adjustment of the shake-legs requires that the screw shall slide in its'tube, and the character of the shaking motion is such as to tend to beget looseness at this fit and to be itself more or less seriously effected by the looseness. Renewable bushings 13 provide for keeping this fit in pretty good conditiombut perfect rigidity of the fit is secured by means of the feather and set-screws, the latter being loosened up a when the adjustment is to be made.

The height of the floor-stands of the truck-mechanism i .t Q, be such as to support the track-rails 32in position over the lower portion of the making-wire when the wire is down. Under normal conditions nothing of .the truck-mechanism will be present except floor-stands 30 and 31.

lVhen-putting the breast-roll .in place, pipe 3'7 is to be placed on floor-stands 30 and 31, and this pipe being a light afi'air can be easily handled without danger of injury to the costly wire. The pipe, when in position on the floor-stand, is to be over the lower member of the making-wire. One of the rails'32 is now to be slid in on this pipe as a safe supporting guide, the angular form of the track well lending itself to 005perative engagement with the guide-pipe, and 'a man at the rear of the machine may then help the front man to place the trackrail on projections of the floor-stands, and the same with the other track-rail 32. Temporary floor-stand 35 and front track-rails as are now to be placed in position and the trucks placed. on the front rails, and the breast-roll placed on the trucks. The trucks with the breast-roll are now to be run in under the machine-frame, in position between the upper and lower members of the making- 7 wire. The breast-roll bearings, hanging 1n free vsuspension, are to be raised andthe breast-roll is to be raised and moved rearwardly so that the bearings may be swung under the breast-roll journals, thus supporting the breast-roll by suspension. The bolt 28 is now to be applied, clamping the breast-roll bearing firmly to the breastroll frame and drawing the breast-roll to its farthest I'GEIIWflIClPOSltiOD. It is to be observed that by this system the makingwire does not, in the operation of getting the 95 breast-roll to place, require to ,be stretched rearwardly beyond its working point. When the breast-roll is lifted'free of the trucks they may be run out to the front of the machine and all of the truck-mechanism re- 100 moved except the permanent floor-stands 30 and 31, and in this operation of removal the guide-pipe 37 again serves in protecting the wire while the comparatively heavy tlllCk-I'flllS are being removed.

In erecting the Fourdrinier frame, or at any time when it is seriously dismantled and disconnected from the shake-im arting mechanism, there is a tendency or the shake-leg system to topple on the floor-trun- 110 nions. In the present case the lugs 43 engag- 'ing the bridges of the floor-bearings limit this toppling motion, thereby preventing damaging twisting strains of the shake-rails and guarding a ainst other damage likely to result from t5: unrestrained side swinging of the structure.
