To all whom it may concern:

Be it known that I, SYDNEY As'roN MER- SEY ROSE, a subject of the King of Great Britain, residing at WValdorf Chambers, Aldwych, in the city of Westminster, London, England, electrical engineer, have invented a new and useful Improvement in and Relating to Recording-Targets, of which the following is a specification.

This invention relates to recording targets, and more particularly to the recorders or indicators for use with targets of that type in which a flexible strip is passed over a series of contacts, one or more of which operates, as the perforation effected by a shot passes over same, to establish an electric circuit for actuating the recorder or indicator.

My present invention consists in certain improvements in the means for recording or indicating the position of the shots on, the

targets.

In the accompanylng drawlngs, Figure 1 illustrates diagrammatlcally an embodiment of my invention which corresponds to that.

shown in section; Fig. 3 is a plan of the indicator with the cover removed; Fig. 4:

is a side elevation to an enlarged scale of the mechanism for releasing the turn table of the indicator hereinafter described, and Fig. 5 is an elevation, with marginal section, of the structure shown in Fig. 4: and looking in the direction of the arrow shown in Fig. 4, parts of the structure being omitted on line mm. Figs. 6 and 7 are detail views of the indicator releasing mechanism.

In carrying out my present invention, electrical means are provided for automatically arresting the movement of the flexible strip, constituting the target, simultaneously with establishing a circuit for operating the recorder or indicator, and after the position of the. shot has been indicated or recorded the winding of the flexible strip is re-started' by electrical means from the firing point.

Referring to Fig. 1, which is a diagram of the apparatus and the electrical connections, the main target is similar to that described in the specification of United States Patent No. 966,361 granted to me,

and comprises a flexible strip 6 which is Specification of Letters Patent.

wound around a drum i, and a number of contacts 6 consisting of numerous fingers placed close together and connected to one The fingers b are arranged on one side of the flexible strip 2, and one of said fingers passes through a perforation i in the strip to make'contact with a conductor Z9 as described in my aforesaid specification. There is one of these perforations i on each side of the representation i of the object to be fired at, and these perforations serve as gage holes for the purpose hereinafter described. Upon the spindle of the drum 2' is mounted a toothed wheel 9 which'meshes with aworm 9 upon a a spindle 0 pertaining, to an instrument 0 (hereinafter described) for indicating upon the replica target a the position of the shot fired at the main target.

The main target and the instrument '0 of the replica target are electrically connected together in the following manner: In a parallel with an adjustable resistance a is a circuit which'commences at the terminal Z of the said resistance, thence passes to the instrument 0, thence to an electromagnet (Z, thence to the target contacts 2) through the hole i whence it returns by way of the conductor 7) and lead h" to the negative main a in which is the other terminal 2 of the adjustable resistance a The adjustable resistance a is energized from the positive main k of a source of electrical energy byway of a circuit a which flows through a lamp a thence to'the positive terminal Z of the adjustable resistance 0., through this instrument to the negative terminal and back to the negative main a Between the terminal Z the instrument a and the negative main a is a switch j which is normally open so that current is normally supplied to the adjustable resistance a and the circuit a. The main circuit flows from the main switch If by way of the lead h of a switch 6, which is controlled by the electro-magnet (Z, and from the other terminal of the switch to the clutch g whence the current is conducted by way of the spindle g and wire 6 to the lead it which is connected with the negative main.

In the working of the apparatus the main switch If is closed and current flows through the motor 71,, which is thereby con tinuously rotated. The adjustable resistance a is also adjusted to supply current to the circuit a. which embraces the electromagnet (Z and energizes the latter to hold the switch 0 open, thereby controlling the circuit which embraces the magnetic clutch. A shot having been fired it may be assumed as having hit the target at say i To ob-. tain a record of the shot the switch 7' is closed. The current now flows from it through a, and switch 3' to the main a deenergizing the electro-magnet (Z' and thus cutting out the circuit a. The electro-magnet being thus deenergized, owing to the circuit a being cutout, the switch 6 is released and closes the circuit f under the action of spring 8, with the result that the current flows from h through the motor 72,, switch 6, magnetic clutch g, and spindle g and thence by way of b and h to the main 64 the circuit f being thus in shunt with the resistance h The clutch 9 thus energized and being driven by the motor it rotates the spindle g which therefore drives the winding drum 2' to wind up the flexible strip 71 and at the same time drives the spindle 0 of the indicator 0. It will thus be seen that as the drum 2' is turned to move the strip 2" horizontally, the indicator 0 is turned simultaneously to move the pointer 0 horizontally and synchronously with the strip. Immediately the strip 2" has commenced to move, the switch j is opened, but the current cannot pass through the circuit a owing to the strip z" keeping the target contacts b separated from 6 since the hole 21 has moved away from the line or conductor Z). The flexible strip continues to be wound until the perforation 2' reaches the target contacts Z), whereupon one or more of these contacts pass through the perforation and immediately closes the circuit a. The circuit a being thus closed current flows therethrough and energizes the electro-magnet (Z, with the result that the switch 6 is attracted, the circuit f opened and the magnetic clutch g deenergized, thus stopping the rotation of the drums and the movement of the indicator 0 in a horizontal plane. The indicator 0 having moved synchronously with the flexible strip the pointer 0 will, when stopped, be at a point on the replica target a corresponding with the horizontal direction of the shot, and the currentfiowing through the circuit a will pass through the instrument 0 and cause the pointer 0 to move in a vertical plane and come to rest incloses the instrument.

at a point corresponding with the elevation of the shot, 0 being a moving coil instrument of well known type. The target contacts 6 are connected together by means of resistances and therefore according to the number of resistances cut in by the perforation 2' so the pointer c is moved to correspond with the elevation of the shot on the target, as will be fully understood from the detailed description of the mechanism hereinbelow. The position of the shot having been register-ed and a fresh target being desired, the key j is operated to cut out the circuit a and to close the circuit f, asabove described, the flexible strip 2" thereupon becoming wound on its roller '5 until the second perforation 2' comes opposite to one or more of the contacts 6 to close the circuit a and thus open the circuit f with the effect, as has been previously described, of arresting the movement of the flexible strip. lVhe'n lights are required for lighting up the replica targeta and the target proper, a lamp 0, may be arranged as shown for lighting the replica target a, and a lamp (4 may be arranged as shown for lighting the target proper. The object to be fired at, as for instance the representa tion of a soldier, as shown in Fig. 1, is printed upon the flexible strip, and the perforations 2' serve to arrest the movement of the flexible strip 2" when the object is in position to be fired at.

Referring now to Figs. 2 and 3, the indicating and registering device 0 consists of an instrument similar to a galvanometer and comprises a pointer 0 which is attached tothe well-known moving coil rotatable within the magnet 70. This magnet is fixed upon a table Z which in the construction illustrated is, by way of example, circular in form and is provided at its periphery with teeth Z which mesh with the worm 0 on the spindle c referred to with reference to Fig. 1. The table is pivotally mounted upon a stand Z and has attached to it one end of a spring Z the other end of which is fixed to the said stand. The spindle c is supported at its inner end in a bearing 0 carried by an arm 0" controlled by a spring a which normally causes the worm c to be in engagement with the table 7,. The outer end of the spindle 0 is furnished with the pulley 0 which is driven by belt 9 from the magnetic clutch g as described with reference to Fig. 1, and this end of the spindle 0 is carried in a bearing a which is pivoted in a support 0 mounted upon one wall of a casing m which Adjacent to the table Z and at right angles to the spindle 0' is a stand 0 furnished at its upper end with two spring arms 12, a each in the form of a flat spring and arranged at right angles to each other longitudinally. The spring arm n is provided at its outer end with a projection or catch 0 and the spring arm 91, is likewise furnished with a projection 01, adjacent to the projection 0 The arm n is provided with a second projection n which extends downwardly into the path of a lug or extention Z mounted upon the table Z. In addition to the extension Z the table is provided with a spring finger Z which extends some little distance beyond the table Z, and with an arm Z of such a length that when the table is in its normal position this armpresses'the spring arm n outwardly. The table Z and its accessories are mounted within a casing m furnished with a translucent disk m arranged opposite to the pointer c and marked to correspond with the representation to be fired at on the target at the butt. A shot having been fired at the target at the butt and the flexible strip having been set in motion as previously described, the magnetic clutch 9 will rotate the spindle 0 by means of the pulley 0, with the effect that the table Z will be caused to rotatein the direction of the arrow in Fig. 3. The rotation of the table is continued until the shot hole i reaches the contacts?) on thetarget and stops the movement of the flexible strip, whereupon the rotation of the table is also stopped. The pointer 0 will thus have traveled horizontally across the duplicate target m corresponding with thetravel of the main target at the butt. The table being now stopped the electric current flows through the instrument and causes the pointer 0 to move in a vertical plane as previously described.

Referring again to Fig. 1, it will be observed that in recording the position of the at and the shot hole '5 consequently the pointer c hasmoved from the position corresponding to the gage hole 6 tothe positi on corresponding to the shot hole 2' Now to set a fresh target at the butt to be firedat and to return the pointer to its normal position, the flexible strip is again set in motion, as has been described, with the effect that the rotation of the table Z is continued in the direction of the arrow in Fig. 3. This continued rotation of thetable brings the spring finger Z against the bearing a which it presses until the extension Z passes beneath the projection n and raises the spring arm a. When the spring arm n is thus raised the upper end of the arm carrying the bearing 0 is released from its catch 0 and the bearing pushed away by means of the spring finger Z so as to release the worm 0 on the spindle 0 from the table. While the table has been rotating in this direction the spring Z (Fig. 4) has been wound, and immediately the worm is released from the table the said spring rotates the table in the opposite direction, thus returning the pointer to its normal position. rapid return of the table Z a dash-pot p is provided During the return movement of To prevent the too the table the return of the bearing 0? is prevented by means of the projection n on'the arm if, as shown in Fig. 7, and when the table has nearly reached the end of its return movement the arm Z on the table enment with the teeth' Z" on the periphery of the latter. The return of the table Z is effected shortly before the gage hole i to the right of the shot hole 1' shown in Fig. 1 reaches the target contacts, so that when the said gage hole reaches the target contacts the pointer 0 is in its normal position. The main target at the butt will now be showing a fresh representation to be fired at and the gage hole 2' last referred to will be at the left hand side of the fresh target and the pointer 0 at the left hand side of the replica target. V f

From the above description it will be understood that the flexible strip is printed with a series of representations to be fired at, and that between each representation is a gage hole which arrests the movement of the flexible strip so as to present a fresh target to be fired at. It will also be seen that in recording the shot and resetting a fresh target the pointer moves horizontally first from the position corresponding to the gage hole on the left hand side of the representation to the position corresponding with the shot hole, and then from this position the 'movement of the pointer is continued-until it is nearly in the position corresponding with the gage hole onthe right hand side of the representatiom the table Zbeing then released and thepointer returned to its normal position. This gage hole now becomes the gage hole on the left hand side of the fresh target and the pointer c is therefore also on the left hand side of the replica target.

The representation to be fired at, instead of being printed upon the flexible strip, may

be printed upon a separate piece of material held stationary in front of a plain flexible strip which is not provided with gage holes. In such a case the shot hole alone is employed for arresting the movement of the flexible strip. To make this clear reference is he d to the diagram in Fig. 1, and let it be assumed thatthe hole 11 on the left is a shot hole from the previous'firing, that the representation of the soldier is on a stationary piece of material. in front of the strip (this piece of material being shown in dotted lines) and that the hole i is the result of a shot which has passed through both the sta tionary piece of material and the flexible strip.

To record the position of the shot hole 2' the apparatus is operated exactly in the manner already described, and When the hole i reaches the target contacts 5 the pointer 0 will be in the position on the replica target corresponding with the position of the shot in relation to the representation, but the representation fired at will remain in its fixed position. That is to say the pointer 0 will have moved horizontally a distance corresponding to the movement of the flexible strip from i to 2' The position of the shot having been recorded the shot hole is now treated as being on the left hand side of the stationary target or representation, and to return the pointer 0 into this position the following means are employed for releasing the table Z. This mechanism is illustrated in Figs. 4 and 5, and consists of a lever fixed to a shaft 9" which passes through the casing and is adapted to be rotated by a head 1*. The lever q is provided with two lateral projections Q2 of which the former engages with an inclined pin 9 upon the upper side of the spring arm n. Assuming the table Zto have rotated to indicate the position of a shot, the spring arm Z will be pressing against the bearing 0 of the shaft 0. To return the indicator to its normal position the shaft 1" is rotated in the direction of the arrow in Fig. 4, whereupon the projection g on the lever Q raises the arm n and releases the bearing 0 from its catch 0 with the result that the spring Z disengages the worm c from the table Z. The table now returns under the influence of the spring Z to its normal position; but the return of the bearing 0 of the shaft 0 is arrested by the other projection g on the lever g. The

table having returned, the shaft 1' is released and the lever Q returned under the influence of a spring Q4, thereby releasing the shaft bearing 0 and permitting the worm c to re engage the table Z.

Although I have described particular means for elfecting the to and fro movement of the table I Wish it to be understood that such means are susceptible of various modifications.

What I claim as my invention and desire to secure by Letters Patent, is

In a recording target the combination with a main target embracing a flexible strip, electrical contacts separated by said strip and means for winding said strip, of a source of electrical energy, an electric motor, a magnetic clutch, a switch in the clutch circuit, a replica target, an electrically operable pointeradjacent to said target and in circuit with said target contacts, a table on which said pointer is mounted, an electro-magnet in said indicator circuit and serving to operate said switch in the circuit of the magnetic clutch, means for driving said table and said winding means simultaneously, and a main switch for controlling the flow of current through said indicator and clutch circuits alternately; the flow of current through the indicator circuit serving to operate the said pointer in a vertical plane and to maintain the said clutch circuit open, while the flow of current through the clutch circuit serves to operate the winding means of said flexible strip and to actuate said pointer horizontallyand synchronously with the movement of said strip.

In witness whereof I have hereunto set my hand in the presence of two witnesses. SYDNEY ASTON MERSEY ROSE. Witnesses:
