ÄN IMPROVED MACHINE REST FOR SMALL ARMS
Year: 1886

page_text: I, JOSEF LIVTSCHAK of Wilua in the Russian Empire, School Teacher,, do hereby
declare the nature of my invention for "ÄN IMPROVED MACHINE REST FOR SMALL
ARMS" 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 reference to improvements in the Machine Rest for Small
Arins described in my Patent Specification of the 24th December 1884 and
numbered 16896.
Referring to the accompanying drawings:-
Figs. 1 to 6 inclusive relate to a form of the machine rest of this invention such
as is suitable for use in the field and may be readily moved from place to place,
Figs. 1, 2 and 3 being respectively a side elevation, a back end elevation and a
plan of the same, and Figs. 4, 5 and 6 representing, details on an enlarged scale.
A is a triangular wood frame to the bottom of which are fixed metal plates a
projecting downwards. N is a slideway having a curved slot x formed therein.
T is an adjusting screw which passes through the curved slot x and is fixed by
means of two wing nuts; by it the fire arm carrier is supported at the back end
and vertically and horizontally adjusted: The elevation of the fire arm may be
adjusted micrometrically by means of an eccentric mechanism similar to that
described in my aforesaid former specification, the object being to provide against
deviation of the projectile by reason of the wind and other action. The fire arm
carrier consists of a longitudinal rail F and two frames V and W fixed thereto and
in which the fire arm is placed as shewn in dotted lines in Fig. 1. The fire arm
carrier is supported in front by a pivotting rod L to which it is jointed at E. The
frame V has a simple prismatic rail m¹ and the frame W an inclined double rail m
on the right hand side of which is a distance scale m'. Previous to placing the
fire arm on these two frames V and W, two clamps or holders v, w shown in
detail in Figs. 4 and 5 are screwed on to the body of the fire arm at a determined
distance from each other. In the bowl is screwed to the arm the recessed
part taking on to the prismatic rail m¹. In the clamp or holder w are two
pivots p, bow w¹ screwed on to the fire arm near the trigger, and hole w³ through
which the belt of the arm may be passed. The fire arm with the clamps or
holders attached thereto is laid on the two frames V and W and its elevation
adjusted by moving it forwards or backwards, a determined position of the fire
arm corresponding to a determined range of fire, to facilitate which adjustment
the distance scale before referred to is provided; it is shewn in Fig. 6; it consists
of a plate in which are a series of holes set out with figures opposite to them to
indicate certain distances of range say from 300 to 1800 metres. Further, on the
fire arm carrier is provided an adjustable water gauge the object of which is
hereinafter described.
Figs. 7 to 12 inclusive relate to a form of the machine rest of this invention
designed for use in fortresses and fixed-positions, Figs. 7, 8, 9 and 10 being

page_text: respectively a side elevation, a back end elevation, a plan, and a part sectional
elevation of the same and Figs. 11 and 12 representing details on an enlarged scale.
This form of machine rest differs from the one already described chiefly in being
of a heavier construction.
A is a T shaped platform, Y an iron frame which serves as a guide for the fire
arm carrier. This frame is carried on pivots y in supports a¹ which are fixed in
the platform A, the frame being capable of turning on said pivots. The other
end of the frame is supported pin jointed, by the adjusting screw T. fixed by
two wing nuts. Thus the frame may be raised or lowered on the pivote y in
which movement it is accompanied by the fire arm carrier F, this latter turning
horizontally on the prolongation of the adjusting screw T and capable of being
fixed in any determined position by the screw i to the curved part y¹ of the
frame Y
The method of operation is as follows:-
In the case of even ground the machine rest is given the desired direction and
pressed into the ground by the plates.a and thus fixed in position. The fire arm
carrier F is given the desired inclination by directing the fire arm to a certain
point and then fixing the same by the pin m³ in the corresponding hole of the
distance scale m*.
The fire arm after attachment thereto of the clamps or holders v, w shewn in
detail in Figs. 11 and 12 and somewhat similar to those previously described, is
placed on the two frames V and W and the pivot p of the clamp or holder w slid
forward until it comes against the pin m³. The chosen distance is marked off
the arm sighted thereto and then the fire arm carrier raised or lowered until the
sight line meets the distance point or point aimed at. The aforesaid, water, gauge
serves for the continuous control of the position of the fire arm carrier so fixed.
It is adjusted horizontally by the set screw z and any deviation of the fire
arm carrier may be at once observed and remedied by operating the adjusting
screw T. It is obvious that the inclination of the fire arm may be adjusted for
any desired range by moving it to correspond with the corresponding .liole in the
distance scale.
In the case of irregular ground the inclination due to the varying altitudes are
ascertained by the sight or range finder, when a sight or range finder is used for
aiming, or by other means, In such cases the machine rest of this invention
affords a sure position and dispenses with the necessity of a fresh aim after
each shot.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim, is:
1. In a machine rest for small arms of the kind described in the patent
specification N° 16896 dated December 24th 1884; The frame V with prismatic
guide rail m¹, and double rail frame W provided with a distance scale or range
scale substantially as described and illustrated. :
2. The clamps or holders v and w substantially as described and illustrated and
for the purpose specified.
3. An adjustable water or other gauge for the purpose of regulating the position
of the fire arm carrier substantially as described and illustrated.
Dated this 21st day of April 1880.
