Specification of Letters Patent.

Patented March 26, 1907;

Application filed uly 19,1906. Serial No. 326.850.

To all whom it may concern.-

Be it known that I, JOHN NICHOLAS MICHEL, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Registering-Target, of which the following is a full, clear, and exact description.

This invention relates to targets.

The object of the invention is to provide means to be used in connection with a target which will indicate the point at which said target is struck by a projectile and which will also indicate the force of the blow delivered by the projectile.

The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of the objective target at which the projectile is thrown.

Fig. 1 is a front elevation of the registeringtarget. Fig. 2 is a vertical cross section through a portion of the objective target and illustrating the details of construction thereof. Fig. 3 is a cross-section through a portion of i a contact-closing device which is operated by '50 and mounted uponthe face of theboard 1 between transverse cleats or strips 4, as

a projectile when it strikes. This view is; a sectionon the line 3 3 of Fig. 2. Fig. 4 is a plan further illustrating diagrammatically the construction of the contact-closing device, and Fig. 5 is a diagrammatic view showing the manner of wiring the target.

Referring more articularly to the parts, 1 represents the b0 y of'the objective target, which consists, substantially, of aboard upon the forward faceof which are arranged aplurality of cushions 2, said cushions being p'referably arranged in rows and close together, as shown. The construction of one of these cushions and the manner of mounting the same upon the board 1 is very clearly shown in Fig. 2. Each cushioncomprises a collapsible body 3, of rubber or similar material. These are of substantiallyrectangular form shown. The bags or collapsible bodies 3 are inclosed in the space between these strips by means of a face-plate 5, which covers the entire faceof the board and is provided with j the target.

openings 6, which receive the necks 7 of buffer-plates 8. These buffer-plates are of substantially rectangular form, as shown in Fig. 1, and substantially cover the entire face of The inner portion of each of the necks 7 is expanded to form a plate or head 9, which rests against the outer wall of the pad or bag, as shown' Itshould be understood that these collapsible bags constitute pneumatic cushions, which are normally held in an inflated condition by means of a coiled spring 10, which seats against the forward wall of the bag and against the forward side of the board 1. Through the board 1- at each cushlon an opening 1s provided 111 which is mounted a thimble 11, and in this thim-- ble there is uided lon 'itudinall a movable plunger 12. The forward face of thls plunger rests agalnst an ad ustable stop 13, wh1ch 1S threaded and mounted in a cross-bar 14 rojectlng diametrically across the tlnmble, as

shown in Fig. 2. On its outer side the plunger 12 is provided with a projecting tip 15.

Against the outer face of the thimble 11 a ball 16 rests, the thimble constituting a seat ther'efor, asshown. The stop 13 is adjusted so that the tip 15 lies against the face of the ball when the cushion is in its inflated condition, such as that shown in Fig. 2.

Behind the board 1 a back board 17 is arranged, which supports a plurality of contact-channels 18, the forward extremities whereof are supported on the rear face of the board 1. These channels incline upwardly toward the rear. They are formed-of insulating material, and each channel isprovided on one side with a continuous contactstrip 19. ()n the opposite side each channel is provided with a plurality of separated contact-plates 20, which are insulated from each other, as indicated. It should be understood that the ball 16 is of metal or similar conducting material and that if it should roll along the channel 18 it will operate to close the circuit successively with the corrtact'plates 20.

At a convenient point to be observed by persons using the device I providea registering-target 2]. This target comprises a faceplate 22, having substantially the same form and dimensions as the objective target, and

it provided with a plurality of dials 23,-

whlch are arranged in rows so as tocorrespond with the cushions '2. Each of these dials is provided with a pointer 24, which constitutes an armature which may be attracted by a plurality of solenoid-cores 25. These cores are arranged circumferentially around each dial, as indicated in .Fig. 5, and are energized by coils 26. These coils are connected in parallel in a circuit 27, which leads from a battery 28, and are connected with return-wires 29, which lead back and attach in succession to the contact-plates 20, as shown. These solenoids are arranged directly beneath numbered points on the dial, which are of successively higher denomination, the return-wire 29 of the solenoid indicating the highest number, (5, which is disposed at the left, including a bell 30, which will ring when the pointer is at the highest possible number. In this way each of the dials is connected with the corresponding cushion 2 through suitable electric conductors or cables 31, as indicated in Figs. 1 and 1. In these views only two of the dials have been represented as connected with the cushions, this being sullicient for the purposes of illustration.

The mode of operation of the target will now be described: A projectile is hurled at the objective target. If it strikes one of the butters 8, it will violently force the same rearwardly, which will compress the air within the collapsible bag 3. In this way an impetus is given to the plunger 12, which imparts a movement to the ball'16. This ball 16 then rolls rearwardly in the channel 18. As it moves rearwardly it bridges the contacts 20 successively with the contact-strip 19. In

this way the solenoids of the corresponding dial on the registering-target are brought successively intoa closed electric circuit. v.As the circuit is closed through the first solenoid it attracts the pointer 24, which moves to a point above it. As it strikes the second contact-plate the pointer is attracted through its corresponding solenoid, and so on. In this way, with the ball moved to the last contact-plate the pointer will move to the lastnumbered point on the dial and the bell 30 will ring. 7 In this way the registering-target will register the point at which the objective target was struck and will also indicate the force ofv the blow delivered. Of course the action of gravity on the ball 16 tends to hold it in position against the plunger 12, and the ball rolls back to this position immediately after the target is struck. When the ball is in its normal position, as indicated in Fig. 5, it is disposed below the lowest contact, so that all the circuits are normally open.

Having thus described my invention, I claim as new and desire. to secure by Letters Patent 1.
