PROVISIONAL SPECIFICATION.
Improvements in and connected with Linch-pins for Artillery and
other Purposes.
1, JAMES RHODES, of No. 1 Sandy Hill, Woolwich, in the County of Kent, en-
gineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to certain improvements in linch-pins for artillery and
other purposes, and has for its object the construction and arrangement of a piu
which is easily placed in position and removed when necessary, but cannot be
accidentally displaced by the vibration incidental to artillery movements.
In order that my said invention may be clearly understood, I have appended
the accompanying sheet of drawings in which Figure 1 is a front elevation of a
linch pin in situ and Figure 2 n side elevation thereof. Figure 3 is an elevation
of the pivotted catch or stop and Figure 4.is a transverse section thereof. Similar
letters of reference indicate corresponding parts throughout the several views.
In carrying my invention into effect I form at the bottom of a linch-pin of the
ordinary regulation pattern, a slot a, which is clear of the axletree when the pin
is in position. A catch or stop a is suspended within the slot b by a pivot c and is
preferably shaped as shown by the transverse section Figure 4, so that the centre
of gravity is below the point of suspension c, and the normal position is as shown
by Figure 1 tending to check or stop the withdrawal of tho linch pin A from the
axle tree B. When it is desired to insert the linch pin, the catch or stop b is
Pressed within the slot a and retained by the finger until the pin A is in position,
when the catch or stop 6 drops by the action of gravity into the position shown and
hereinbefore described. By a similar operation the pin A may be withdrawn.
When the linch pin A is in position there is sufficient play, or freedom to com-
pensate the vibration of traffic, but the arrangement and balancing of the catch b
is such that it cannot be accidentally displaced sufficiently to allow of the with-
drawal of the pin.
By the employment of liuch pins made according to my said invention, the
leather thong stops heretofore used for the purpose are dispensed with, and a per-
fectly secure stop provided which is always ready for use, cannot be deranged by
ordinary usage, nor choked by dirt, and is always attached to the pin.

page_text: same is to be performed, to be particularly described and ascertained in and by
the following statement:-
My invention relates to certain improvements in linch-pins for artillery and
other purposes, and has for its object the construction and arrangement of a pin
which is easily placed in position and removed when necessary but cannot be
accidentally displaced by the vibration, incidental to artillery movements, or in
heavy traction generally.
In order that my said invention may be clearly understood I refer in the follow-
ing description to the drawings apponded to my provisional specification in which
Figure 1 is a front elevation of a Linch pin in situ and Figure 2 a side elevation
thereof. Figure 3 is an elevation of the pivotted catch or stop, and Figure 4 is
a transverse section thereof. I also append to my complete specification a sheet of
drawings in which Figure 5 is an elevation of a regulation artillery linch pin
fitted according to my invention and Figure 6 is a side view thereof. Similar
letters of reference indicate corresponding parts throughout the several views.
In carrying my invention into effect I form at the bottom oftan ordinary linch
pin a sota which is clear of the axletree when the pin is in position. A catch or
stop bis suspended within the slot a by a pivot c and is preferably shaped as
shown by the transverse section, Figure 4, so that the centre of gravity is below
the point of suspension, and the normal position is shown by Figure 1, tending
to check or stop the withdrawal of the linch pin A from the axletree B. When
it is desired to insert the inch pin, the catch or stop b is pressed vortically within
the slot a, and retained by the finger until the pin A is inserted into its place in
the axletree B, and when it is "home" the catch or stop drops by the action of
gravity into the position shown by the drawings, and hereinbefore described. By
a similar operation the pin A may be withdrawn.
b
When the linch pin A is in position there is sufficient play or freedom to.com-
pensate the vibration of traffic, but the arrangement and balancing of the catch
or stop 6 is such that it cannot be accidentally displaced sufficiently to allow of the
withdrawal of the pin.
By the employment of linch pins made according to my said invention the
leather thong stops heretofore used for the purpose are dispensed with, and a per-
fectly secure stop provided which is always ready for use, cannot be deranged by
'ordinary usage nor choked by dirt, and is always attached to the pin.
Figures 5 and 6 simply show the adaptation of the device to an ordinary artillery 3
linch fin in common use.
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:-
First. In a linch pin the employment of a catch or stop pivotted within a slot 4
in said pin, substantially as and for the purposes herein described and shown by
the appended drawings.
Second. In a linch pin as referred to in the preceding claim, the method of, and
means for inserting into and withdrawing from the axletree substantially as herein
described, with reference to the drawings.
