The r wer re uir d to ef es t i vibratory movement of the support is, with this arrangement, little, if any, greater than that required to revolve the unbalanced weight, provided the support is positively connected with and is arranged to be moved in timed relation with the weight.

ins en ce has o t p l Object the proyision of a shaking or vibratory frame for the web formin se tio of a Fourdrinier paper making machine in combination with a rotating unbalanced weight, so that an efficient shaking movement is imparted to the frame.

It is a further object of the invention to provide a construction in which the vibratory movement imparted to the frame is in a horizontal direction, any vertical vibratory movement of the frame being substantially eliminated.

It is a further object of the invention to provide a simple construction by which the vibratory movement imparted by the weight may be va ried as desired within the limits of the mechaism- It is a further object of the invention to produce a simple and compact mechanism for effecting these desired results, the parts of which are readily accessible for adjustment and repair.

With these and other objects not specifically referred to in view, the invention consists in certain novel combinations, parts and arrangement which will be described in connection with the accompanying drawings and the novel features pointed out in the claims hereunto appended.

Figure 4 is a plan view, partly broken away, of the construction shown in Figure 1;

Figure 5 is a side elevation of the web forming part of aFourdrinier paper making machine, showing the table rolls, the framing for supporting these, and the making wire, and

Figures 6, 7 and 8 are diagrammatic views showing the means employed for preventing vertical movement of the shaking frame of the machine in several modifications. 4 Referring now to these drawings and first to Figure 5, there is shown the web forming section of a Fourdrinier paper making machine the parts of which are suitably supported in standards 1, 1' of suitable. configuration. This section in- 3 cludes a breast roll 2, a set of table rolls 3, and the making wire 4:, this latter being endless and passing over a couch roll not shown, and tension rollers,- one of which is shown marked 5.

These parts are supported in stationary sideframes (Figure 1) 6, 7, but the table rolls and certain associated parts are supported on these side frames so as to have a horizontal vibrating movement sidewise of the stationary supporting frames. As shown, the bearings 8 of the table rolls are supported on a pair of shaking or vibratory frame members 9, 10 which in turn are mounted on flat springs 11, 12.

The stationary side frames 6, '7, before referred to, are, as shown, hollow and the springs 11, 12

are secured in these side frames and to the shaker frames in any suitable manner. As shown, the lower ends of the springs are secured by bolts 13 -to the under side of the frames 5, 6, and the upper ends of the springs are secured to heads 14, havbe effected in various ways, in the particular construction illustrated these tie members are in the form of

hollow tubes

18, 19, the ends of which are provided with

extensions

20, 21 to which the shaker frames are bolted by bolts 22, these tubes partaking of the sidewise movement of the shaker frames 9, 10, before referred to.

In the best constructions, so as to permit an adjustment or control of the vibratory movement given the shaker frames, as more fully hereinafter referred to, resilient means are provided which control the vibratory movement of these frames. The particular construction of these resilient means may be somewhat varied, but they will preferably be provided at a plurality of points so as to provide an even vibratory movement for the shaker frame section. As illustrated, secured as by bolts 23 to the outer sides of the stationary frames 6, 7 are recessed members or

bonnets

24, 25, forming seats for one end of coiled springs 26, 27, these springs seating, at their other ends, in recesses 28 formed in the ends of the tie tubes l8, 19, before referred to. Passing through the bonnets, springs and tie tubes are adjusting rods 29, on the ends of which are hand adjusting wheels 30. These wheels operate left and right hand threaded members 31, 3 2, and through sliding collars 33 act to increase or decrease the tension on the springs 26, 27, two of the springs of each set being thus simultaneously adjusted.

In accordance with the invention, there is provided a construction including an unbalanced weighted rotating member for effecting the shaking or vibratory movement of the shaking frames. In the best constructions, a plurality of sets of such mechanisms will be provided, and in the best constructions, furthermore, each mechanism, for reasons hereinafter referred to, will include two such weighted members which are rotated in opposite directions. Two such mechanisms are shown, but as their construction is identical but one will be described indetail. These mechanisms, being marked generally 34 and 35 in Figure 4, and the mechanism 35 will be described in detail.

Referring to Figures 1, 2, 4 and 6, the mechanism includes a pair of

rotary members

36, 37, shown in the form of wheels or discs, which are mounted on

shafts

38, 39, hereinafter referred to. Each of these wheels supports a weight, marked 40, 41, this weight being located at a fixed predetermined distance from the axis of the wheel and being of a predetermined amount, depending on the extent of the vibratory movement desired. While an effective result can be obtained by the use of one unbalanced weighted wheel, two weighted wheels preferably are employed and where such construction is adopted the wheels will be driven so as to rotate in opposite directions, as by intermeshing

gears

42, 43.

Referring to the diagrammatic view of Figure 6, which is the preferred arrangement, assuming the lower wheel 37 is driven in the direction of arrow A, it will in turn, by means of the

intermeshing gears

42, 43, drive the upper wheel 36 in the opposite direction, as indicated by the arrow B. With this arrangement, the centrifugal action produced in the lower wheel by the unbalanced weight will be down, andthat of the upper wheel will be up, so that the two will balance each other and there is no tendency to produce a shaking action in a vertical direction. However, as the weighted parts of the wheels move toward the left, their centrifugal action will be combined on that side until they have passed their horizontal center position, when they both will be moving toward the right and will combine their centrifugal action on that side. Thus the full centrifugal action of the weights is obtained first to one side of the centers and then to the other in a horizontal direction, but with little or no tendency to have a vibratory action in a vertical direction. Thus a very even predetermined vibratory movement may be transmitted to the shaker frames 9, 10 through connections which will now be described.

The two weighted wheels, where two are employed, are carried in a two

part casing

44, 45, the parts of which are suitably secured together by bolts 46. This casing is supported on four

rocker arms

47, 48, 49, 50, which at their lower ends are pivotally mounted in blocks 51, bolted or otherwise fixed to

extension members

52, 53 secured to the stationary frame 7 before referred to, these extensions being strengthened by struts or braces 53'. At their upper ends, the rocker arms are pivotally secured to the casing sections on pivots 54, 55 mounted in extensions 56, 5'7 on the casing.

The

casing

44, 45 is rigidly connected with one of the shaker frames, as the frame 9, by a pair of rigid bars or

rods

58, 59 securely held in place to the frame by bolts 60, and to the frame 9 by bolts 60. It will be seen that with this construction the rocking action of the casing caused by the centrifugal motion of the unbalanced rotating wheels is transmitted to the shaker frames and the desired reciprocating movement of these frames is effected. The extent of this movement is readily and easily controlled by the springs 26, 27, and a very effective result is obtained. It will be observed that the flat springs 11, 12 supporting the shaking frames 9, 10 are substantially the same length as the

rocker arms

47, 48, 49, 50 so that the vibrating or shaking movement will be substantially parallel, thus resulting in the desired even operation of the parts.

The weights may be secured in the rotating members or wheels in any suitable manner. As shown, the wheels are recessed at 61 in Figure 2 to receive the weights.

The wheels may be driven in any suitable manner. In the particular construction shown, where a plurality of vibrating or shaking mechanisms are employed, each such mechanism is provided. with an independent driving means. As shown, the vibrating mechanism 34 is driven from a motor 62, and the vibratory mechanism 35 is driven from a motor 63. Referring to the mechanism 35, the shaft 39 of the wheel 37 is extended and has secured thereto a sheave or pulley 64 over which passes an endless cable 65, this'cable also passing over idler sheaves or pulleys 66, 67 supported on shafts 68, 69 supported in brackets '70, '71 depending from the

extensions

52, 53, before referred to, which support the casing. The

cable also passes over a driving sheave or pulley sired, however, the different units may be driven

plings

75, 76, in which arrangement the speed of both vibratory units will be the same.

In Figures 7 and 8, two modifications of an unbalanced wheel arrangement are shown which may be employed under some circumstances. As

shown in Figure '7, the wheels may be arranged side by side horizontally instead of vertically as in Figure 6, or they may be arranged as shown in Figure 8, with appropriate mechanism for driving them in different directions, as shown by the arrows. The particular mechanism selected to Fourdrinier paper making machine as described, but it will be understood that the invention is adapted for use and may be used in other types or characters of mechan'smhaving a shaking or vibratory part to which it is desired to impart a controlled shaking action.

The invention has been shown and described in its preferred form. It will be understood, however, that one vibratory unit, or as many as may be desired, can be employed and that while two unbalanced rotary members preferably are used for each unit, one such member is within the invention. It will be understood therefore that various changes in the arrangement and construction of the parts may be made without departing from the invention as defined in the appended claims.
