SHARING MECHANISM.
Application filed September This invention relates to improvements in shakingw mechanisms and more particularly to the means for varying the amplitude of the vibrations. It is frequently desirable 1n shaking mechanisms to vary the amplitude of the vibrations, and in mechanlsms of this kind which are used in connection with, paper making machines it is desirable to vary the amount of the shake so asv to obtain the desired interweaving of the fibres for varying grades of paper and varying grades of 111 I t is therefore an object of this invention to provide a shaking mechanism in which the amplitude of the vibrations may be varled. while the machine is in operation.
It is also an object of this invention to provide a shaking mechanism of this class which is adapted to be used in connection with a paper making machine. I
' It is a further object of this lnvention to provide an adjustable shaking mechamsm for use with a Fourdrinier machine.
It is also an object of this invention to provide a device of this class in which a biased shaft slidably engages a movable block so as to vary the distance between the center of said block and the axis of rotatlon of the shaft.
Other and further important ob ects of this invention will be apparent fromthe disclosures in the specification and the acc0m-. panying drawings. a
This invention in a preferred form) is illustrated in the rawings and hereinafter more fully described.
On the drawings: Figure 1 is a plan view of the shaking mechanism.
block is shown in Figu Figure 2 is a cross section along line 22 I of Figure 1.
Figure 3 is a cross section along line 33 of Figure 1.
Figure 4 is a side view of the adjustable block removed looking towlard the left as the Figure 5 is a side view of the block bearing with the block removed looking toward the right of Figure 1.
Figure shows the shaking mechanism 6, 1924. Serial No. 738,271.
connected to a paper making machine of the 6 rigidly secured to the base structure (see also Fig. 6). A sleeve 7 is rotatably supported in the bearings 2 and 3. Keyed to the sleeve 7 is a large gear 8 which by means of a gear 9 is driven by a motor 10. Integral with the end of the sleeve 7 is a guide 11 a left side view of which is shown in Fig. 5. Upon either side of the guide 11' is a rear guide late 12 (Fig. 1) secured thereto by bolts tting into threaded apertures 13 (Fig. -5). I
By turning to Fig. 6 is seen slidably mounted on the guide 11 a block or crosshead 14 containing a non-central aperture 15. A connecting rod 16 is strapped to the block 14 which is suitably journalled therefor. Within the sleeve 7 is a shaft 17 one end of. which is deflected to slidably engage the aperture 15 of the block 14.- Near its other end the shaft 17 is reducedto form a journal: 18 and collar 19. The journal 18 is rotatably supported by a bushing 20 rigidly secured in a sleeve 21 by bolts 22as shown in detail inFig. 2. The sleeve 21 is longitudinally slidable in the bearing 4 and is apertured and threaded at one end to receive the screw end of an adjusting shaft 23. The
The operation is as follows:
The motor 10 transmits a rotary motion to the sleeve 7 by means of the, gears 9 and 8 (Fig. 1). Since the block 14 is secured against rotation relative to the sleeve 7 by means of the guide 11 (see Fig. 6), the two members 14 and 17 revolve together. As the block 14 revolves with the sleeve'7, the connecting rod 16 connected to the former is given a reciprocating movement. The amount of this reciprocating movement 1s dependent upon the amount that the block 14 is offset from the center line of the sleeve 7. By rotating the wheel 25 in a clockwise direction the sleeve 21 is drawn to the right in the bearing 4 carrying with it the shaft 17. The shaft 17, by means of its deflected end engaging the non-central aperture of the block 14 causes the latter to move from central position as the former moves to the right thus giving a variable degree of eccentricity to the mechanism which is controlled by the wheel 25.
In the preferred embodiment, the reciprocating motion of the connecting rod 16 is transmitted to the bell crank lever arm 28 (Fig. 7) which through the pivot shaft 28, shaking post 31 and connections therefrom to the table roll rails 35 transmits thereto a lateral vibratory movement the amplitude of which is adjustable by the wheel 25 of the shaking mechanism.
What I claim as new is:
1. A shaking mechanism in combination with a paper making machine and means comprising a sleeve, a deflected shaft, and a block engaged by said shaft slidable on said sleeve for adjusting the amplitude of the vibrations transmitted to said machine by said shaking mechanism.
2.

3. A shaking mechanism in combination with a paper making machine comprising a connecting rod on said shaking machine, a bellcrank lever connected to one end of said rod, a shaking post on said bell crank lever, a table roll rail connected to said shaking post, and springs supporting said rail and means for adjusting the amplitude of the vibrations transmitted to said machine by said shaking mechanism.
4. A shaking mechanism in combination with a paper making machine comprising a connecting rod on said shaking machine, a bell crank lever connected to one end of said rod, a shaking post on said bell crank lever, a table roll rail connected to said shaking post, and springs supporting said rail, and means comprising a sleeve, a deflected shaft, and a block engaged by said shaft slidable on. said sleeve for adjusting the amplitude of the vibrations transmitted to said machine by said shaking mechanism.
5. A shaking mechanism in combination with a paper making machine comprising a connecting rod on said shaking machine, a bell crank lever connected to one end of said rod, a shaking post on said bell crank lever, a table roll rail connected to said shaking post, and springs supporting said rail, and
means comprising a sleeve a deflected shaft,
a block engaged by said shaft and slidable on said sleeve, a second sleeve and a threaded shaft rotatably engaged in said second sleeve for adjusting the amplitude of the vibrations transmitted to said machine by said shaking mechanism.
