Improved Machine for Disintegrating and Pulverizing Hay, Straw,
and the like.
We, CARL JULIUS OLSEN and HANS PETER KJÖLLER, both of Copenhagen in
the kingdom of Denmark, Gentlemen, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
Our invention relates to a machine for disintegrating straw, hay and the like in
such a manner, that the said material becomes a more valuable feeding article than
ordinary chaff. Ordinary chaff suffers from the defect that the nourishment which
it contains, never can be completely got advantage of, because the outer hardened,
thin silicious crust, which surrounds the straw, is not broken in the chaff machine
and interferes to a great extent, with digestion of the chaff.
By means of the machine according to our invention this defect has been remedied.
The straw, and the like is not simply cut, but is torn to shreds, whereby the said
outer crust is completely disintegrated so that solution and digestion of the nourish-
ment is greatly facilitated. The effect obtained by means of this machine is therefore
in reality that a like quantity of chaff yields a larger proportion of nourishment,
which means that it is more valuable.
The manner in which we prefer to carry our invention into effect is shewn in
the accompanying drawings in which Fig. 1 shews the machine seen from the end
with the working parts in vertical cross section and Fig. 2 shews the machine in right
angle to Fig. 1 with the working parts in vertical longitudinal section.
In the machine-stand A, beds are provided for two shafts B and C, of which the
former is the main driving shaft and the latter the shaft which works the mechanical
parts. The driving shaft carries the larger toothed driving wheel D, which is
geared in the tooth-wheel E on shaft C, which shaft therefore receives a large
speed. This shaft carries two discs F & G, to the circumference of which the disin-
tegrating knives a are fixed. These knives have a very peculiar shape and it is
mostly on this, that the disintegrating process depends. The knives edges are
toothed, shaped and fixed in such a way, that, when placed edge to edge, the teeth
fit into each other, being thereby capable of tearing any straw brought between
them. The opposite knives 6 are fixed on bars K which are screwed firmly between
two discs L & M which are firmly connected with the machines main stand, and
through which the shaft (passes loosely.
The described machine disintegrates the straw etcetera into various degrees of fine-
ness, which may be regulated by employing a sieve the mashes of which are of a
certain fineness. This sieve is shewn in Fig. 2 and indicated by letter N. It is
placed in the opening P. Q., made between the firm-fixed knives. When the machine
is at work the sufficiently disintegrated straw etcetera particles are thrown through
the sieve, outside which they are collected in a suitable manner. By employing sieves
with greater or smaller mashes the disintegrated straw etcetera may be obtained in
corresponding fineness.
