Improvements in Saddles for Supporting Fallers in Preparing
Boxes and like Machines for Operating upon Wool and similar
Fibres.
We, TOM CHAPMAN, of 31 School Hill, Windhill, Shipley, in the County of York,
Mechanic, and JAMES MASKER, of West Brook Works, Thornton Road, Bradford,
in the said County, Machine Broker, do hereby declare the nature of this invention to
be as follows:-
This invention has for its object the construction of the upper saddles upon which
fallers travel in preparing boxes and other faller machines in such a manner that, the
saddles can be adjusted so that the cams on the top and bottom screws operate the
fallers that they enter the spaces of the screw threads with greater certainty, and with
less liability of the pins of a faller being damaged by striking the underside of the
preceding faller, as the former is being raised by the cams of the bottom screws.
We accomplish the above object in the following manner-Each top saddle we
make in two parts, with a feather key on each, which enters and fits a recess formed
in the supporting bracket. The bottom saddles are of the ordinary construction, as
are also the conductors, screws and cams thereon; but by making the upper saddles
in two parts, the space between the ends of same and conductors can be adjusted so
that, on the cams operating the fallers in a downward or upward direction, there is
only sufficient working space or clearance for the fallers to pass from one screw to
another, that they enter direct into the respective screw spaces without the liability
of being twisted, or the rising fallers damaging the pins as is often the case when
the ends of the saddles are worn shorter or the faller ends thinner than when new.
The plates forming the two saddles are jointed in the centre, one portion overlapping
the other, so that there is no open space between the two to interrupt the smooth
traverse of the fallers; and in addition to the saddle bars being secured to the
supporting brackets in the manner described, we attach them together by a screwed
rod which passes through projections, the same being secured to the saddle plates and
the bar held by nuts, by the regulation of which, either end of a top saddle may be
adjusted to lead the fallers direct into the spaces of the threads.

page_text: We, TOM CHAPMAN, of 31 School Hill, Windhill, Shipley, in the County of York,
Mechanic, and JAMES MASKER, of West Brook Works, Thornton Road, Bradford, in
the said County, Machine Broker, 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 :-
This invention has for its object, the construction of the saddles upon which fallers
travel in preparing boxes and other faller nachines, in such a manner that, the surface
plates of the top saddles can be adjusted so that the cams on the top and bottom
screws operate the fallers in such a manner, that they enter the spaces of the screw
threads with greater certainty, and with less liability of the pins of a faller being
damaged, by striking the underside of the preceding faller on being raised by the
cams of the bottom screws; and consists in forming each top saddle surface in two
parts securing them to suitable brackets, and connecting them together by a screwed
rod, by which they may be accurately adjusted, so that there is only sufficient working
space or clearance for the fallers to pass from screw to screw.
In the accompanying drawings, Fig. 1 represents the front view of a faller saddle
with our invention added thereto; Fig. 2 a plan of the same; Fig. 3 an end view ;
and Figs. 4, 5 & 6 detached details drawn to a larger scale.
The different classes of machines to which this improvement may be applied are all
in which fallers are used and operated by screws shown at S, S, in Fig. 3, which are
mounted and rotated in the usual manner.
At each side of the machine, secured to the framework in the ordinary manner,
and in the usual position, is a saddle bracket A, the bottom surface B of which, and
the conductors C and C with spindle and spiral spring P thereon are ordinary, and
to which we make no claim as forming part of this invention.
The upper surface of each saddle upon which the top series of fallers traverse, we
form with two plates D and D', reducing the same in the centre for some distance to one
half the thickness, and making slot holes through which are passed screws for securing
them to the projecting flange A¹ of saddle bracket A; and for further security, and
keeping the top surface of the two plates straight in the same relation to each other,
we form on the back of each, feather keys E, E, which fit and rest in a groove F cut
in the said projecting flange.
To each portion D and D₁ of the top saddle surface, we secure a projecting stud G,
through both of which we pass a screwed bar H, having a nut J, on each side of the
said studs, by which it will be readily seen, that on the plates D and D¹ being set

page_text: the necessary distance from the respective conductors C and C₁ for the fallers to pass
from screw to screw without liability of derangement, the said plates can be rigidly
secured by the before named set screws, and by the screwed bar H and nuts J.
On either end of the plates D or D¹ becoming worn, that there is more than the
necessary clearance or working space between the plate and conductor, the former
can be adjusted so as to give the necessary space in the manner as before described,
and thus keep the requisite working clearance, that the fallers pass direct into the
thread spaces of the top and bottom screws, and thus prevent the liability of the fallers
twisting, or the rising fallers damaging the pins as is often the case when the saddle
plate ends are worn shorter, or the faller ends thinner than the normal length or
thickness of the same.
Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination with a saddle bracket of two or more plates D and D' secured
thereto and braced together by a screwed rod H substantially in the manner and for
the purpose set forth.
2. The combination with a saddle bracket of two or more adjustable surface
plates D and D for the purpose described.
