page_text: I, AUGUSTO STIGLER, Engineer of 10, Via Castelfidardo of Milano in the
Kingdom of Italy, do hereby declare the nature of this invention to be as
follows:-
Various kinds of bearings for shafting have been designed for the purpose of
affording a suitable support which shall be capable of adjustment both horizontally
and vertically, and be also capable of rotating both horizontally and vertically.
All the constructions however which have been hitherto proposed, possess various
drawbacks. In one pattern for instance disproportionately long loose pivots are
required for the bearing proper, and this last has to be attached to the pivots by
clamp screws, an arrangement which is unserviceable for use with tight driving
belts; moreover the parts of the bearing are held fast by. the clamp screws in such
a manner that the same loses its mobility so that such a bearing is in reality only
movable while it is being fit up; another proposed device possesses similar draw-
backs: in consequence of the parts of the bearing having to sustain great strain
owing to the design of the mechanism they have to be made disproportionately
heavy, moreover the bearings being constructed of a number of pieces, some of
which are difficult to make, the use of such bearings has hitherto been restricted by
reason of their high first cost.
In order therefore to obviate these drawbacks and especially to arrange the
bearing proper close to the main support and to maintain the same movable even
after it has been mounted, the inventor has designed the arrangement which forms
the object of the present application for Letters Patent.
By means of a special adjusting piece which is so shaped that the portion of the
bearing which supports the driving shaft lies in the plane of the horizontal pivot
of the adjusting piece, hereby it becomes possible to employ the same adjusting
piece as well for hanging bearings as also for cornice bearings and the like, and
notwithstanding this to keep the mechanism so simple that the construction is
easy and the material is employed to the best advantage, the bearing being in
consequence cheap to make.
The vertical pivot of the bearing proper is upheld by an exterior adjustable piece
from whose upper end a horizontal pivot proceeds. This second pivot fits in a
horizontal sheath in one piece with the main frame of the bearing. Both pivots
can revolve in their sheaths and can be adjusted axially being each provided with

page_text: a screw by means of which the horizontal and vertical adjustment of the bearing
is effected. For this purpose the sheaths are provided with prolongations, each
bored out to admit of the corresponding screw passing through and being clamped
to it by nuts screwed on the said screw, The special design of the adjustable piece
renders it possible that the bearing of the supporting mechanism of the horizontal
pivot can be most effectively arranged. The pivot can also be prolonged to a
considerably length and therefore adequately supported so that the yielding of the
piece is minimised. A bearing constructed in the above described manner is both
firmer and at the same time simpler and lighter than any contrivance yet brought
forward for the same purpose, notwithstanding which, the bearing when mounted
retains its mobility, because the nuts even when tightly screwed up, permit the
pivot to revolve which is not the case with lock-nuts." The adjusting piece of the
hanging bearing is identical with that of the cornice bearing, and if desired
the pivot of the same adjustable piece may be located in a main bearing of
different shape. The construction of the mechanism is perfectly simple and conse-
quently easily manufactured on a large scale.

I, AUGUSTO STIGLER Engineer of 10 Via Castelfidardo, of Milano, in the
Kingdom of Italy, 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:—
Various kinds of bearings for shafting have been designed for the purpose of
affording a suitable support, which shall be capable of adjustment both horizontally
and vertically, and be also capable of rotation both horizontally and vertically.
All the constructions however which have been hitherto proposed possess various
drawbacks. In one pattern for instance, disproportionately long loose pivots are
required for the bearing proper, and this last has to be attached to the pivots by
clamp screws, an arrangement which is unserviceable for use with tight driving
belts moreover the parts of the bearing are held fast by the clamp screws in such
a manner that the same loses its mobility, so that such a bearing is in reality only
moveable while it is being fit up. Another proposed device possesses similar
drawbacks: in consequence of the parts of the bearing having to sustain great
strain owing to the design of the mechanism, they have to be made dispropor-
tionately heavy; moreover the bearings being constructed of a number of pieces
some of which are difficult to make, the use of such bearings has hitherto been
restricted, by reason of their high first cost. In order therefore to obviate these
drawbacks and especially to arrange the bearing proper close to the main support
and to maintain the same movable even after it has been mounted, the inventor
has designed the arrangement which forms the object of the present application for
Letters Patent.
By means of a special adjusting piece which is so shaped that the portion of the
bearing which supports the driving shaft lies in the plane of the horizontal pivot of
the adjusting piece, hereby it becomes possible to employ the same adjusting piece,
as well for hanging bearings as also for cornice bearings and the like, and notwith-
standing this to keep the mechanism so simple that the construction is easy and
the material is employed to the best advantage, the bearing being in consequence
cheap to make.
In the accompanying drawing, the mechanism is displayed both as a hanging
bearing Figures 1 and 2, and as a cornice bearing Figures 3 and 4, each in two
views, and partially in section. As is obvious from the Figures, the vertical
pivot C of the bearing proper, C with top brass B is upheld by the exterior
adjustable piece D' from whose upper end a horizontal pivot D projects. This
pivot D fits in a horizontal sheath a in one piece with the main frame of the
bearing A. The pivot C and D can revolve in their sheaths D¹ and a, and can
be adjusted axially, being each provided with a screw d' and d by means of which
the horizontal and vertical adjustment of the bearing is effected. For this purpose
the sheaths D¹ and a are provided with prolongations ƒ and g each bored out to
admit of the corresponding screw passing through and being clamped to it by
nuts i screwed on the said screw,

page_text: As shewn in detail in Figure 1, the special design of the adjustable piece D D¹
renders it possible that the bearing B C can be arranged quite near to the sup-
porting mechanism of the horizontal pivot D. The pivot D can also receive a
bearing for a considerable length, and therefore be adequately supported so that
the yielding of the piece D D¹ is minimised.
A bearing constructed in the above described manner is both stronger and at the
same time simpler and tighter than any contrivance yet brought forward for the
same purpose, notwithstanding which, the bearing where mounted retains its
mobility, because the nuts i even when tightly screwed up, permit the pivot to
revolve which is not the case with lock nuts. The adjustable piece D D₁ of the
hanging bearing is identical with that of the cornice bearing, and if desired the
pivot D of the same adjustable piece D D may be located in a main bearing of
different shape.
The construction of the mechanism is perfectly simple and consequently easily
manufactured on a large scale.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to
me by my foreign correspondent, I declare that what I claim is:
In universal joint bearings for shafting the combination of parts consisting
essentially of vertical sheath D' supporting the cylindrical pivot O¹ of the bearing
proper, together with a horizontal cylindrical pivot D projecting from the upper
end of the sheath D, which pivot D is carried by a sheath forming part of the
main frame of the bearing in such a manner that the adjustment of the pivots C¹
and D can be effected by screws d and d passing through the corresponding
projections and g of the sheaths the said pivots being secured to the sheaths by
nuts substantially as described. .
