Complete Specification Left, 10th Aug.. 1888
Complete Specification Accepted, 14th Sept., 1888
I, HUGH ROBERT STEWART of 21 Great George Street in the City of Westminster
late Captain in the Royal Navy do hereby declare the nature of this invention to be as
follows:-
My Invention relates to pack saddles such as are described in the Specification of
my application for Letters Patent No. 8081 dated 4th June 1887 and more especially
the form shewn at Figs. 3 and 4 of the drawings accompanying that Specification
and my present Invention has for its object to provide a device whereby any
tendency there may be to slackening of the fastening devices of the adjusting arms is
prevented.
According to my Invention I form or fix on one of each of the pairs of arms a
screw nut through which I pass a screw and on the other of each pair of the said arms
I fix or form a bearing piece so that when the saddle is adjusted to the required extent
on the said screws being brought to bear on the said bearing pieces thrust due to
outward pressure on the parts of the saddle is taken by the said screws and bearing
pieces. There are preferably such screws and bearing pieces on each pair of arms at
reverse sides of the centres although I may use the device on only one pair of such
arms if desired.

Improvements in Pack Saddles.
I, HUGH ROBERT STEWART of 21 Great George Street in the City of Westminster
Captain in the Royal Navy do hereby declare the nature of my Invention and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
My Invention relates to pack saddles such as are described in the Specification of
Letters Patent No. 8081 granted to me as of the 4th day of June 1887 and more
especially to that form which is shewn at Figures 3 and 4 of the Drawings accom-
panying that Specification and my present Invention has for its object to provide an
improved arrangement whereby any tendency there may be to slackening of the
fastening devices of the adjustable arms is prevented.
I have illustrated in the accompanying Drawing my present invention. Figure 1
being a perspective view of a pack saddle with my improvement applied and Figure 2
an enlarged detail in side elevation of my improved device. I form or fix on one of
the pairs of arms B a screw nut or projection with a female screw in it (marked b¹)
and through this I pass a screw d³ and on the other of each pair of the said arms I fix
or form a bearing piece 62 so that when the saddle is adjusted to the required extent on
the screws d³ being brought to bear on the hearing pieces 2 thrust due to outward
pressure on the parts of the saddle is taken by the said screws and bearing pieces and
the arms B are effectually prevented from altering their relative position after adjust-
ment. There are preferably such screws and bearing pieces on each pair of arms at
reverse sides of the centres although I may use the device on only one pair of such
arms if desired. I have shewn in the Drawing only the central screw b of the
arrangement Figures 3 and 4 of my aforesaid Specification but I may use also
the screws d if so desired or any other convenient device for securing the arms B
together.
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
In pack saddles of the kind described the combination of a bearing piece on
one of the arms of the pair at one or at both ends of the saddle tree and an adjustable
counter bearing piece or screw on the other of the pair of arms substantially as
hereinbefore described.
