TAR GET AND AUTOMATIC INDICATING APPARATUS.

SPECIFICATION forming part of Letters Patent N 0. 643,173, dated February 13, 1900. Application filed January 20, 1899. Serial No. 702,843. (No model.)

'VIERSEN, mechanician, MATHIEU PIERRE THEODORE DAMALVY MOLIERE, merchant, and CAREL ELIZA TER MEULEN, merchant,

subjects of the Queen of the Netherlands, re-

siding at Amsterdam, in the Kingdom of the Netherlands, have invented certain .new and useful Improvements in 'largets and Automatic Indicating Apparatus Connected Therewith, of which the following is a specificalion, reference being had to the accompanying drawings, in which- Figure 1 is a front elevation of the target with the front plate or wall of the lateral box removed; Fig. 2, aplan with the cover-plate of this box likewise removed. Fig. 3 is a plan; Fig. 4, a transverse section of the indicating apparatus. Fig. 45' is a plan of a branch-pipe connection on a shooting-place, Fig. 4: a transverse section of this connection, and Fig. 4 an elevation of the indicating apparatus, said Figs. 4, 4 and 4 being drawn on a larger scale.

This invention relates to an arrangement for automatically indicating the hits on targets.

The said invention is designed not only to make any attendance unnecessary at the tar: get, but also to obviate the risk of damage by the shots incident to the known targets provided with arrangements for automatically indicating and generally made of metal.

A further advantage consists in the extremely accurate never-failing marking of the shots, which can be read off exactly on an indicating apparatus at the firing-place itself. Moreover, by simplifying the apparatus at the target more rapid firing can take place, and so on.

The said invention comprises an arrangement at the target and an indicating apparatus at the firing-point which are electrically connected. It is characterized, essentially, by the arrangement of a moving continuous band or strip of paper or other soft easilyperforated material behind the target-disk, which is-made of pasteboard, the said band or strip being perforated by the shot at the same time as the target. After each shot the band or strip is drawn along from behind the target by means of a rotary sector and then clamped fast, after which the sector moves back alone to its original position and by so doing comes behind the part of the strip which was previously behind the target. On the surface of the sector are arranged metal rings which correspond exactly to the target-rings or to the various sections thereof and are in connection by wires with an elec tric battery. These wires are led to the indicatin g apparatus at the firing-place. Th us after having been drawn along each part of the paper band or strip occupies exactly the same position relatively to the ring-pieces of the sector as it occupied relatively to those of the target when behind the latter. As soon as the sector is returned to its original position a metal brush, which is connected with the other Wire of the electric battery, is moved along the surface of the sector. The paper band or strip is non-conducting. As soon as the brush touches the ring or a part thereof through the hole in the band contact is made, and it is shown exactly at the indicating apparatus at the firing-point which ring-section of the target has been hit. The operation of the apparatus then begins afresh,

since the rotation of the sector is effected from thefiring-point.

The paper band is wound upon a roller at one side of the target to the same extent that it unrolls on the other side. The holes can be afterward pasted over and the roll of pa per thus used again.

The indicating apparatus can be introduced into the circuit at various distances from the the shots. They are arranged obliquely to the plane of the target. In the box B, at the left-hand side, a paper-roller P is rotatably mounted on a vertical shaft, and in the box a roller P in a similar manner, so that a band or strip p of paper, which unrolls from the roller P to the same extent, is rewound onto the roller P, and the roller P can be forcibly set in rotation in any suitable manner. By these means the band or strip is kept continually stretched. A sliding brake deviceb b is provided on the shaft of the roller P. Guiderollers L L serve for guiding the paper band correctly. In the box O the sector S is pivotally mounted on a vertical shaft 5. The breadth of the said sector measured on its so rface is exactly that of the target. A number of metallic electrically-conducting ring-sections I, II, III, IV, and VI of exactly the size of the rings of the target are mounted on the surface of the sector, Fig. 1. The rings are cut through along the horizontal and vertical center lines, so that each ring, as well as the central circular surface, is divided into four parts corresponding to those of the target according to which the marking of the shots generally takes place. Each of the twenty ring sections or pieces thus formed is electrically insulated from the adjacent ones as well as from the sector itself. A Wire a, which is located in the circuit of an electric battery B, Fig. 2, leads from each ring-section to a bar 0, secured at the side of the sector close to the shaft 5, which bar is provided with twenty angle irons or pieces 0, bearing cont-actsprings 0 A second bard is secured to the side wall of the box and likewise receives twenty angle irons or pieces (1, which again are connected to the conducting-Wires from the firing-point, and when the sector is in the position shown in Fig. 2 these angle-pieces make contact through the springs c with the ring-sections on the surface of the sector. On the shafts a frame R is mounted so as to turn loosely thereon, which frame can move around the sector. On the vertical rod thereof is secured a metallic brush D over the entire height of the sector. The brush or the frame is connected with the other wire of the battery.

The paper bandp from the roller P is first led over the guide-roller L and then along close behind the target over the sector S, being also guided in the slots in the side walls of the boxes B and C. After this it is conducted between two clamping-bars E E, then over the guide-roller L, and, finally, it is wound upon the paper-roller P. After each shot the sector S moves inward from the position shown in Fig. 2 into the position shown in dotted lines further into the box O and takes the band p with it, since the said band is held At the in the side wall to the corner of the drawn-in sector. The distance between the points at the ends of this straight line is made equal to the breadth of the sector measured on the surface or equal to the travel of the sector, so that should the sector be moved back into the original position, Fig. 2, the band being meanwhile held between the clamping-bars E E and the clamping device F released, the rings I V on its surface will come to lie exactly in the same position behind the paper band as the identical rings on the target which were previously in front of the particular part of the paper band. If the frame R, with the metallic brush D, is then moved along the sector, as soon as the .brush passes the perforated hole contact is made with the particular ring-section on which the hole lies, and the result of the shot is thus transmitted by means of the wire a and contact-pieces c c d', and soon, to the indicating apparatus at thelfiringpoint and is read off thereon.

We will now more fully explain the motion mechanism and other parts in the box O and then describe the arrangement of the indicating apparatus at the firing-point.

The motion of the sector is preferably effected by means of clockwork, which is actuated by a weight orspring on the shaft w, Fig.

1. It comprises bevel-wheels 7c 70 and spurwheels r r, of which 0" sets a vertical shaft 2; in rotation. On this shaft are mounted a cam 75, a circular disk 25, and a crank K, Figs. 1 and 2. The crank connected to the sector by means of the connecting-rod Z. On the periphery of the disk is a projection 92. This projection strikes in the position of rest against a detent or armature m of an electromagnet M, which then arrests the rotation of the clockwork. The electromagnet M is located in the circuit of an electric battery G Fig. 2, the conducting-wires leading to the firing-points. If now the armature m be attracted by completing a circuit at the firingpoint, the projection 01 will be released and the clockwork will set the sector in motion. The cam '6 serves for clamping together the clamping-bars E E for holding fast the paper band from the moment that the sector moves back again, and consequently at the moment that the crank K moves past the other deadpoint. For this purpose the connecting-rod Z is connected to the one-armed lever H, the free end of which acts by means of a roller on the periphery of the cam t. This connectingrod, by means of a double lever h on the vertical shaft h, presses the bar E at the top and bottom firmly against the fixed bar E over the whole height of the paper band. The bar E is again released as soon as (after a fresh shot) the sector moves inward from its original position, Fig. 2, and allows the paper band, which is then wound up to the same extent by the roller P, to pass through. The paperroller P is alsomoved by clockwork actuated by a spring or weight on the shaft 10 through bevel-wheels e e and spur-wheels f f. The armature m only releases the fly of this clockwork during the inward mot-ion of the sector, during which time the paper band is consequently carried along by the sector and must be wound up by the roller P. This fly and the other parts belonging thereto may be assumed to be known, and are therefore not shown in the drawings. The clamping device F is arranged in the right-hand upper and lower corner of the sectors. It is to hold the paper band fast duriu g the inward motion of the sector and be otherwise out of action. To the lower and upper clamping-jaws F are attached the connecting-rods Z the other ends of which are each secured to a twoarmed lever 11, turning on the sector. The lever H is pressed toward the right by means of a spring f and the clamping-jawsF thus held in their released position. If, however, the free arm of the lever H strikes at the end of the return motion of the sector against the stop a, the lever H swings about its fulcrum or pivot and closes the clamping-jaws F. The lever is then held in this position by the detent r and it is not released, and the jaws consequently are not released until the detent r in the other extreme position of the sector strikes against the stop a so that during this time-that is, during the inward motion of the sector-the said sector takes the paper band with it. The frame R for the metallic brush D is held at the top and bottom by the detent r on the common shaft 1' in the position shown in Fig. 2, and this detent is released by arms a on the sector as soonas the latter is returned to its original position. Operated by a spring, the frame then moves along the sector and contact is made through the hole in the paper, by means of the brush, with the ring-section on the surfaceof the sector, which section is identical with the annular section of the target which has been hit. At the end of its travel the frame strikes against the arm a on the sector and is returned during the inward motion of the sector, by means of this arm, into its original position, wherein it is again engaged by the detent T The indicating apparatus at the firing-point consists of a flat cylindrical box N, which can be secured on a flange F at the end of the pipe P in which the twenty electric conductors are arranged, Figs. 3, 4, and 4c. In the cover of this box are arranged twenty holes Z in the form of a cross, these holes corresponding to the ring-sections on the target. Round plates a, bearing the numbers of the rings, are arranged within the box N in rows soon as one of the ring-sections is hit. This is effected in the following manner, viz: The plates z are capable of turning about a vertical axis and are held by means of the armature i of an electromagnet g, of which one is provided for each plate in the box N. Each of these electromagnet-s g is connected with one of the twenty conductors corresponding to its position in the box or to that of the plate 2 belonging thereto. If contact be made by the motion of the brush on any one of the ring-sections of the sector, the electromagnet g of the corresponding plate 2' attracts the armature i and the plate springs forward and leaves its number visible through the aperture Z. An extension 2 of the plate a lies against a stop .2 on a rod .9, of which there are four arranged crosswise in the box N. These rods .9 are pivotally connected at the center of the box to a rotary plate 19, and one of them extends at its other end outside the box and is there provided with a knob K. It will be seen that by pressing in the knob K all four rods 8 will be simultaneouslypushed in, and therefore the forwardly-moved plate in any row will be returned to its normal position. After each shot-that is to say, as soon as the brush passes a hole in the paper band and makes contacta number will become visible in one of the four rows, and by pressing back the knob K" the apparatus is set afresh for indicating the result of the next shot.

As already mentioned above, the indicating apparatus can be inserted into the circuit at any usual shooting distance. At each of these points branch wires extend from the conductors in a cylindrical box V on the flange F of the pipe P These branch wires are fastened all around to the inner periphery of the cylindrical box V, the one Wire end being duly insulated from the next, Figs. 4 and 4t".

Beneath the box N is arranged a block or piece W, which fits exactly in the cylindrical box V and has a four-cornered hole Z in the center. The hole Z fits, in one definite position only, onto a suitable projection n in the cylindrical box V. Around the block or piece .W are arranged twenty contact-springs o, to

which are connected the wires of the box N. The twenty springs make contact only with the ends of the twenty wires arranged at the inner periphery of the cylindrical box V. In this manner the electromagnet of one ringplate Z is at each firing-point always connected with the same wire only of the con ductors. A single indicating apparatus is thus suificient for several firing-points of one shooting-place.
