The present invention relates to a device for mixin'g fibrous materials such as for example woodwool, coco fibre and asbestos with binding media such as plaster, cement, magnesite and the I like in dry, fibrous or pasty'form. Such mix-- tures are used, for example, in the manufacture of sheets for light building construction. It is known to mix moistened, long-fibred material with cement in amachine, in'which the.
' fraction of a turn of the driving shaft, the forks eflecting their oscillatory movement around a moving turning point.
Now, it was found, that in such devices the fibrous material could be substantiallyfed forward only by pushing further fibrous material so through the machine, inasmuch as the stirring forks did not impart to the fibrous material any forward movement at-right angles to their own planes of motion. This resulted in the material accumulating in the machine, thus causing imzg perfect mixing, a circumstance which, especially 1 in the case of glutinous binding media such as,
plaster led to much inconvenience, in addition to deterioration in the quality of the product produced.
so Further, in the known device fibrous material became stuck in the bottom part of the housing between adjacent forks since this material'was not moved back into the plane of motion of the forks.
as The main object of the present invention is to provide an improved construction of mixing device from which these drawbacks are eliminated.
This object is achieved by causing the forks of the mixer to oscillate'in a plane which is inclined in relation to the vertical. The simplest way'of doing this is for example to locate themlet end of the device and consequently also the corresponding end of the crankshaft which moves the stirring forks, at a higher level than the delo livery end.
.In addition to obtaining a suitable staggering .of the stirring forks the high speed of the crankshaft ens'ures' that the mixture moves forward across the forks, thus ensuring perfect mixing so and at the same time a large output without-overfilling the machine.
i, The device according to the invention is able to deal with binding media in liquid or pasty form,
' and it' is particularly suitable for mixing fibrous 5 material with such binders as plaster, which set Germany 1, 1937, Serial No. 11am 7 Germany November 1'1, 1936 very quicklyand are in the form of a heavy and glutinous paste, as the thorough mixing of the materials is effected exceedingly uickly.
A further object of the invention is to provide means for causing the material which slips down between the forks to be immediately gathered up and fed back into the plane of motion of the succeeding fork which throws it upward, thus preventing binding media from adhering to the walls of" the housing, or sitting there and then being detached later and spoiling the mixture. For this purpose according to the invention a reciprocat ing motion is imparted to the housing relatively to the forks. Y
The .manner in which'the above mentioned and further objects of the invention are attained will become clear from the following description of the embodiment of the invention illustrated inthe accompanying drawing, in which: 7
Figure 1 shows a transverse section of a device constructed according to the invention, the section being taken on the line l-l of Figure 2. namely in the plane of motion forks; and i r Figure 2 illustrates a longitudinal section.
The crankshaft c, which is driven in any suitable manner via the flywheel a, is mounted in an inclined position in the bearings r, 1' which .are attached to a suitable framework 10. The crankshaft c carries a number of forks d arranged in staggered formation. Each fork d is also controlled by a lever l, which is articulated at the point -.u on the fork and at the point 't on the frame 10, in such a way that the tips of the forks describe an ellipse-shaped curve It.
The housing g is shaped to correspond to the upward movement of the tips of the forks d and has on its underside the wheels e which run on the rails n of a frame m which forms aninclined plane.
By means of the driven crank it journalled at 11 between the rails n and by a connecting rod 1 which is articulated to the housing 9 at the point 3 a to-and-fro motion is imparted to the house fibrous material is fed into the machine in the" manner indicated in Figure 2, and the bind ing medium, whichis preferably in. liquid or paste form is added to the fibrous material at the point indicated'bythe arrow p. e If liquid or pasty binders are mixed into the fibrous material it is no longernecessary to extract excess moisture by means of hydroex- 1 tractors as is often the usual practice after mixing in the known machines.
of one of, the
When using glutinous mixing materials, such as plaster, one or two-pronged forks have been found to be particularly advantageous, as they are easy to draw out of the mixture and do not impede the passage of the mixing material from one fork to another.
What I claim and desire to secure by Letters Patent of the United States is:
1. Apparatus for continuously mixing and transporting fibrous materials and binders comprising a mixing trough, a frame extending adjacent to and longitudinally of said trough, a shaft supported in said frame, said shaft being offset to form crank sections, stirrers actuated by said crank sections, said trough and said shaft being inclined.
2. Apparatus for continuously mixing and transporting fibrous materials and binders comprising a mixing trough, a frame extending adjacent to and longitudinally of said trough, a shaft supported in said frame, said shaft being offset to form crank sections, stirrers actuated by said crank sections, said trough being inclined, being open at the top and on the three sides, and being shaped in correspondence with the path followed up by the stirrer tips and means to impart to said trough a reciprocative movement.
