APPARATUS FOR SIGHTING cuss.

SJPEGIFIOATION forming part of Letters Patent N6. '2 16,114, dated December 16, 1902. Application filed August a, 1901. SerilNo. tints. (to model.)

To and whom it may concern:

Be it known that we, CHARLES PROSPER EUGENE SCHNEIDER, ironmaster, and J EAN BArTIsTE. GUSTAVE ADoLrHE CANET, engineer, residing at Le Oreusot, Saone-et-Loire, in the Republic of France, have invented certain new and useful Improvements Relating to Apparatus for Sighting Guns, of which the following is a full, clear, and exact specification.

This invention relates to apparatus for sighting guns.

Hitherto sighting apparatus,properly speak ing, has comprised a foresight and a rear sight. The fore sight requires to be placed at a somewhat great distance from the rear sight to allow of a sufficient length of sightline,'and in order to render the sight-line independent of the movements of the gun as independent support of considerable length is required for carrying the sighting apparatus. On the other hand, if the rear sight is carried by a short support it provides a limited field within which corrections for drift and the laying of the gun can be eifected.

The improved sighting apparatus constructed according to this invention obviates these objections. It enables the fore sight to be dispensed with and yet retains the advan tages of a line of sight of convenient length. Furthermore, while forming a small compact apparatus mounted in a socket on a support permanently connected with the pointing mechanism of the gun it permits of both the laying of the gun and the making of correetions for drift in a plane of movement of three hundred and sixty degrees. It also has other advantages which will be hereinafter explained. a

In order that our invention may be clearly understood and readily carried into efiect, we will describe the same fully with reference to the accompanying drawings, in which Figure l is a side elevation of the complete apparatus as seen from the left. Fig. 2 is a plan of the same. Fig. 3 is a side elevation of a portion of the apparatus as seen from the right. Fig. 4 is a rear elevation. Fig. 5 is a vertical longitudinal section taken on the line C D of Fig. 2. Fig. 6 is-e vertical transverse section taken on the line AB of Fig. 5. Fig.

7 is a horizontal section taken on the line E F of Fig. 5. Fig. Sis a horizontal section taken on the-line G H I J of Fig. 5. Figs. 9and 10 are elevations showing another embodiment of the invention.

The sighting apparatus comprises three main partsviz., a goniometer, an eyepiece or telescope, and a level-which parts areconnected together in and upon a socket c, serving as a support for the entire apparatus and having at its upper edge a graduated scale (1. For preparing the gun ready for action the apparatus is secured by means of its socket to asolid support integral with the pointing 'mechanism, from which it may be removed when desired. In the interior of the fixedsocket c-is a hollow rod or movable socket a, which is adapted to turn about its axis and forms a sleeve supporting the eyepiece-carrier e. v

j in is a ring supporting the level 70 and capable of being turned around the said socket c by reason of its being loosely connected therewith by an annular rib engaging with a corresponding annular recess, Fig. 5.

' The goniometer comprises the fixed graduated socket c and the movable socket a. The latter is furnished with asign orindex 1, Fig. 1, which is capable of being adjusted and fixed adjacent to any of the larger divisions of the graduated scale (I.

3 is a toothed crown formed integral with the socket c and with a passage for the movable socket a. It is provided with teeth equal in number to-the larger divisions of the graduated scale d. (See Figs. 5 and 8. These teeth are kept normally in engagement with the teeth of a similar toothed crown 4: on the movable socket a, Fig. 8, by a spring 1', provided in the interior of the socket c and surrounding the movable socket a. By depress ing the socket a so as to compress this spring the movable toothed crown 4 is separated rienie geous to divide the scale dinto four parts of a circle, each part or quarter being divided into ten large divisions, making forty large divisions all the way around scale (1, each of said divisions corresponding to one of the teeth of crownB, asalready stated.

The eyepiece-carrier e is formed integral with a stem 19, that fits loosely and concentrically in the movable socket a, so as to be capable of rotating around the same axis as the latter. Angular displacement of the car- -rier e relatively to the socket a can be effected as follows: A box q, forming part of the socket a andprojecting laterally therefrom, supports aspindle s, on which is mount-- ed a worm t and a graduated milled head f. With the worm t engages a toothed helicoidal segment v, projecting from the lower end of the eyepiece-carrier a. (See Figs. 5 and 7.) Upon the support q and integral with the socket a, is formed an index 2 adjacent to the -graduated milled head f.

The graduated scale, in connection with the milled head f, is formed on a drum g and has a hundred equal divisions. The segment '1) is so adju'sted that the line ct sight is exactly parallel to the axis of the gun. when the milled head is set at zero. The hundred divisions of the graduated scale of the milled head f correspond to one division of the scale (1. The total amplitude of the movement of the milled head f therefore. corresponds to one-fortieth of the circle of movement on the scale d.

a It will thus be'understood that by turning the milled head f a distance of one division of its graduations the eyepiece is displaced a distance of one four-thousandths of the said I circle of movement.

The carrier 6 comprises a carriage forming a guide for the eyepiece proper or collimator which protects V g The guide and the correspondingsurface of the casing form an arc of a circle, the said casing being provided on one of its sides with divisions in hundredths of the circumference and the carrier e with an index 5. The divisions of the ct ing tare marked from a zero-point in two di -;etions for measuring angles in positive and negativedirections. The angular movementof easing t',withits collimator hin the vertical a passing through the longitudinal axis e carrier e, is obtained by means of a rant: 6, Figs. 3, 4, and 6, connected with the i, and a spiral-toothed wheel 7, fast on the spindleSof the carrier e. On the same spindle is a milled head j, which is provided with a drum graduated into fifty divisions and with the numbers running'in two opposite directions.

axis of the socket c. Acomplete'turn oi the milled head 3' corresponds to a half-division of a graduation .on the casing 2', so that by means of the said milled head j it is possible to estimate elevations or depressions of the eyepiece in one ten-thousandthsof the circumference. Astud 11, provided on the carrier 6, serves as a stop for limiting the movement of the casing 'i.

The level is pivotallymounted on a pin Z, disposed in a plane at right angles to the axis of the goniometer and carried by the ring m, which latter, as already explained, embraces the socket c and is capable of turns ing' around the latter. The said ring m carries a sector n, which serves as a guide for the level in its movement around the pivotal axis Z. The said sector is graduated in hundredths of the circumference ofthe circle of which it forms part, and the level which moves over and in front of the said graduated sector is fiirnished withanindex 14.

When the zero of the graduations of the sector lies opposite the index l-l, the axis of the level is in a plane at right angles to the axis of the socket c. The sector is fitted with a toothed rack 12', gearing with a spiral pinion that is fast on the spindle 13, carried by the level, and such spindle is fitted with a milled head 0. This head is provided with a drum circumferentially divided into one hundred equal parts marked with two sets of numbers running in opposite directions. It is thus possible to estimate or adjust the angular disten-thousandths of the cirplacement in one cumference of the circle the level describes around its pivot Z. This particular arrangement of the level on the support of the goniometer permits of the rapid adjustment of the angle of sight with great precision, of laying the gun of imparting or measuring the angle of drirt, and of ascertaining and correcting the inclination of the trunnions.

As shown in Figs. 9 and 10, the sighting instrumentalities may comprise a telescope 15, provided with a collimator h, pivoted thereto on an axis cc, so as to be capable of adjustment parallel to the axis of the telescope. In this arrangement the outer sleeve of the telescope forms the carrier for the collimator, taking the place of carrier 8 of- Figs. 1 to 8, the construction shown in Figs. 9 and 10 being the same as that of the other figures, except as to the differences just explained.

The telescope furnished with a cross-wire and a micrometer enables indistinct objects to be sighted with great precision, distances and heights to be measured, and lateral angles to be ascertained.

What we claim, and desire to secure by Let'- ters Patent of the United States, is-

support mounted on and rotatable about the socket, a level pivoted to the support, a second support rotatable within the socket, and a sighting instrument having connection with said second support.
