COMPLETE SPECIFICATION.
An Improved Lubricating Mechanism.
I, FLORA AUGUSTE SATTLER, of 35, Zwickaue rstrasse, Crimmitschau, in the
Kingdom of Saxony, and German Empire, 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:-
The subject of the present invention is a process and apparatus for the economical,
cleanly, and simultaneous lubrication of a number of bearings as for instance the
foot and neck bearings of the spindles in self-actors, spinning, doubling, or spooling
machines by means of consistent fat, by the use of which not only considerable
saving is effected in lubricant but also in time and cost of labour; moreover by
this means the troublesome scattering of fluid oil is altogether avoided so that
the material worked by the machine as well as the machine itself will be kept
cleaner and the spindle straps will no longer be kept moist which consequently
causes the same to last longer.
In the accompanying drawing the arrangements necessary for the carrying out
of the process are shown in three modifications and moreover,
Figure shows a front view,
Figure 2 a section, and
S
Figure 3 in plan and partial horizontal section one modification, in which at the
height of the neck and foot bearings of the spindles S square or rectangular hollow
bodies made for instance out of thin sheet zinc are made use of, which bodies are
provided at the side turned to the spindle bearings and exactly corresponding to
the division of the spindles with little conical tubes t, which tubes deliver into holes
bored in the spindle bearings. A metal strip u fitted into the hollow space in the
direction of its length serves as piston, which can be moved gradually from the
outer to the inner inside of the hollow space by means of a small screw » passing
obliquely through and threaded somewhat at its end. The said piston piece u lies
at first close to the outermost inner side in the direction of the screw head.
Through slots two in the upper wall of the hollow space s, which can be closed by
means of little slides x, the lubricating fat is conveyed by means of injectors or in
other suitable manner into the hollow space and the same filled therewith. If this
little screw be now turned along the whole front to a very small amount, say one
eighth revolution, the piston piece u will thereby be moved to the inside against the
lubricant and this latter pressed through the tubes t into the spindle bearings to the
spindle itself, which effects the division of the lubricant by its own revolution, or
in the case of neck bearings if necessary also with the assistance of a slot which is
cut in the bearing longitudinally or spirally. By the single one eighth turn of the
screws the whole of the spindles will be sufficiently lubricated for a whole working
day at least.
A further modification of the described lubricating apparatus is shown in the
accompanying drawing in
Figures 4 to 6 in which
Figure 4 shows the same in section
Figure 5 in front view, and
Figure 6 in plan and partial horizontal section. In this modification the prism
shaped hollow body consists of two troughs a b engaging one within the other
which serve to hold the fat; the pieces i secure the connection of the same.
The
trough a is screwed by means of hollow screws t to the spindle boxes corresponding
to the division of the spindles (Figures 4 and 6). By means of the hollow screws t
as many angles k as there are spindles are secured in the interior of the trough a

page_text: (Figure 6); in place of the piston piece u there is arranged in this case a piston
plate c which also (corresponding to the spindle division) is provided with angle
pieces h. This piston plate c lies on the inside of that wall of the trough closely
and can be adjusted sideways in the direction of the arrow. Hereby the lubricant
between every two angles hk is pressed together, and as it can find no other escape
is forced through the hollow screws t whereby the whole of the spindles S receive
at the same time the same amount of lubrication. In order to shut off the angle
pieces hk from the inner walls of the trough, strips of leather are secured to the
former, which press with their edges upon a. When the fat is consumed the
pieces are disengaged, the trough and piston plate c taken out, or off, the trough a
is again filled and the parts cb again put in place.
Figure 7 of the accompanying drawing shows in section
Figure 8 in front view and part longitudinal section, and
Figure 9 in plan, and part horizontal section a modification of the lubricating
device described in which the more strongly made trough a secured by means of
screws to the spindle support, serves at the same time as the common bearing for
all the spindles or spindle pivots. The special spindle box frames as well as the
hollow screws t and the angular pieces are not required in this case because,
firstly, the spindles themselves oppose sufficient resistance to the lubricant on the
sideways removal of the plate c, and secondly, because they revolve uninterruptedly
in the trough. By means of the two last described arrangements, the lubrication
of all the spindles can take place simultaneously and during the working which was
quite impossible in the method of lubrication hitherto employed with oil. Moreover
a machine provided with the arrangement described requires a much less amount
of motive power because spindles and spindle bearings are permanently enveloped
by a layer of lubricant whereby the friction is reduced to a very slight amount.
Moreover the material of which the spindles and the spindle bearings are made
suffers much less wear than hitherto.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The process for the economical lubrication of many bearings especially of
spinning and doubling spindles characterised by the simultaneous pressing in of
cousistent fat from a closed prism-shaped holder by means of the displacement of a
piston plate to the bearing of a number of pivots placed close together.
2. A mechanism for the carrying out of the process set forth in Claim 1 in which
the piston plate u is pressed by means of screws v in the direction perpendicular to
the spindle of the hinder wall of the prism-shaped container s, and thereby the
lubricant in the latter is pressed through hollow screws t in the spindle bearings.
3. A modification of the device set forth in Claims 1 and 2 in which the
prism-shaped lubricant container consists of two troughs ab engaging the one
within the other, of which the one is provided internally with angle pieces and
in which the fat between two angle pieces is pressed together by the sideways
displacement of a piston plate e provided with angle pieces and forced through
the hollow screws t into the spindle bearings.
4. The modification of the arrangement set forth in Claims 1, 2 and 3 in which
the trough a serves at the same time as a bearing for all the pivots whereby the
separate spindle bearings, the hollow screws t and one half of the number of the
number of angle pieces k are rendered unnecessary because the spindle itself supplies
the requisite resistance to the fat on the movement of the piston plate c.
