SIGHTING APPARATUS FOR GUNS.

' Specification of Letters Patent.

Patented Jan. 11, 1910.

To all whom it may concern:

Be it known that we, GHARLEs PROSPER EUGENE SCHNEIDER and EMILE RIMAILHO, residing, respectively, at Le Creuzot, Saoneet-Loire, France, and at 54 Boulevard Maillot, Neuilly-sur-Seine, Seine, France, have in vented a new and useful Improvement in or Relating to Sighting Apparatus for Guns, which is fully set forth in the following specification.

This invention relates to sighting apparatus for guns, and has for its object to correct errors due to the inclination of the axle.

Heretofore, sighting devices have been placed either upon the gun, the trunnion for example, or upon the cradle, or upon the gun carriage, and when the apparatus is carried by the trunnion of the gun, articulated supports have been employed to permit of correcting the influence of the inclination of the axle.

According to the present invention the device is constructed in such a manner that the necessary correction is obtained in a more eliicient manner than has heretofore been practicable, in the case in which the sighting deviceis carried by the cradle or the carriage.

In order that the novel device may be readily understood it is desirable to indicate briefly the means employed for obtaining the correction when the supports of the sighting device are fixed to the trunnion of the gun.

Figures 1 and 2 of the accompanying drawing are diagrams relating to these known means. Figs. 3-6 illustrate the improved device, Fig. 3 being a view in side elevation, showing the connection between the gun mount and the gun and the sighting devices carried thereby; Fig. 4 is a section on line A-A, Fig. 3; Fig. 5 is a sectional view on line 13-13 of Fig. 3; and Fig. 6 illustrates diagrammatically a connection when the sighting devices are suspended from the aiming sector.

In Fig. 1, t is the trunnion of a gun the axis of which is projected at 0. Ordinarily the support a of the sighting device is suspended from the trunnion t by a lnnge 6 parallel with the longitudinal axis 0-0 of the gun. This support may be displaced around its hinge by means of a screw 'v,' it carries a level n and a slghting device 0 situated upon a rod 05 forming part of a shaft e capable of rotating with slight friction in the support at around the geometrical axis 2-2 (Fig. 1). In the position represented in firm lines in Fig. 1, the plane of sight is the plane parallel with the axis of the gun, passing through the line 11. When the screw 'v is rotated this plane remains parallel with the hinge b which is parallel with the axis of the gun and this plane is vertical when the bubble of the level nis between its marks. If the axle, and consequently the axis of the trunnions t are inclined by an angle or along 3-3, the plane of fire of the gun is still the vertical plane 00 passing through the axis of the gun; in order that the plane of sight may be parallel with the plane of fire, it is necessaryto act upon the screw 11, in order to bring the bubble back between its marks, and, as stated above, in this manner the plane of sight is rendered vertical and parallel with the axis of the gun, and therefore parallel with the plane of fire, by bringing the parts into the position indicated in broken lines in Fig. 1. hen however the angle of elevation ,8 is given, as indicated in firm lines in the diagram Fig. 2, the line of sight is inclined and directed skyward. In order to bring it back on to the target which is on the ground it is necessary to turn by hand the rod cle around the geometrical axis 22 (Fig. l), in such manner as to bring the line of sight downward, the parts c-cl then assuming the position 0 (l indicated in broken lines in Fig. 2. The novel device permits, in short, of obtainin the following results :1. The plane of sight is kept parallel with the plane of fire, assuming the gun trunnions are horizontal, and is kept approximately horizontal when they are inclined, although the support a of the sighting device is not carried by the gun itself. 2. The connection of the support a with the part from which this support issuspended, and the gun, is such that the line of sight remains stationary when the elevation of the gun alters; this dispenses with the maneuver for returning the whole crle to c (Z -e, (Fig. 2).

In Fig. 6 the sighting device is shown suspended from the aiming sector 71. which is provided with a hollow trunnion y having a bearing in the gun carriage f and which receives the trunnion t of the gun. The sector it engages on the gun a pinion p and on the gun carriage a similar pinion 1) whereby the sector may be caused to rotate with respect to the gun carriage, or the gun may rotate with respect to the sector. In either case the hinge 1) remains parallel with the axis of the gun.

Referring to Figs. 3-6, the device comprises a trunnion g, parallel with the trunnions of the gun, and rocking in the carriage f', or in a bracket /L forming part of the carriage, or in a similar bracket forming part of the sector It (Fig. 6). This trunnion y carries .a hinge 7) parallel with the axis of the gun, and maintained parallel with this axis owing to a connection between 9 and one of the trunnions t of the gun, causing 1 to follow all the movements of L. In the constructional form represented, the two trunnions g and t carry two pa "allel projecting arms of the same length Z and m to the extremities of which there are jointed the two heads of a connecting rod 2, in such a manner that t and g are the apexes of an articulated parallelogram. A part p, which in its turn serves as pivot for the support a of the sighting devices cn, is capable of turning around the hinge b. It is obvious that the whole g-Z)p is able to rotate without necessarily entailing the rotation of the support a. An adjusting screw 1; supported upon the bracket it permits of rocking the whole (1/ 1) around the hinge b in order to return the support a to the vertical position. The nut of this screw instead of being formed, as in the known devices, in the support a itself, is constituted by an independent part '1", a kind of carriage guided normally to the median plane of the gun upon an arm 8 forming part of the carriage or of the cradle, or fixed upon the bracket 71. The head to of the screw is prevented from longitudinal displacement in such manner that the rotation of the screw causes the longitudinal displacement of the nut upon the arm 8. Now, the nut carries a spherical stud u engaged in a cylindrical socket 9, formed in the support a, or in an appendix projecting from this latter. The diameters of the socket and of the spherical stud are such that the sphere always has a great circle in contact with the inner surface of the socket. hen, by maneuvering the screw 11 longitudinal displacement of the nut 1' is produced, a rotation of the whole )-a around the hinge b is produced, the socket q inclining upon the spherical nut it according to requirements; and if by means of the level, the support a has been made vertical, it is maintained in that position whatever may be the vertical inclination given to the gun, because the whole gbp rotates in the said support. The plane of sight may accordingly be rendered parallel with the plane of tire by manipulating the screw 0 whatever the inclination of the trunnions t of the gun may be, and may be maintained so whatever inclination may be given to the longitudinal axis of the gun.

\Vhat we claim and desire to secure by letters Patent ot the Iinited States is 1. In a device for automatically correcting for the inclination of the gun trunnions, the combination of a revoluble shaft parallel to the gun trunnions, means connecting said shaft with one of said trunnions to cause the shaft to follow the rotation of the trunnion. a sighting device support, a member having one end in revoluble cngagement with said support and having the other end hinged to said shaft, a displacing screw having a traveling nut provided with a ball bearing, a socket in said support for receiving said ball bearing and adapted to maintain the plane of sight ertical while permitting said plane to remain parallel to the axis of the gun.
