TARGET APPARATUS FOR USE WITH KINEMA'IOGRAPHS.

' Barns, HENRY.WELDON KELLY, 'and Douc- LAs Haynes Coanm, subjects of the King of Great Britain, residing at 128 Great Col- "f more.street,,Birn1ingham, 36 St. Peters road,

Birmingham. and 80 Lionel Handsworm,Ir Jstreat,.BirrhimnLjiint-he county of War- -wick", England, have invented a netvand useful Target -Apparatus"for U se with Kinematographs; and we do hereby declare the following to be a full. clear. and

exact description of the same.

Our invention comprises improvements in target apparatus for use with kinematographs and the like and refers moreparticularly to that class in which a picture is' produced upon a perforatable screen, the screen having a light at the rear which is visible through the bullet hole when a shot U passes through the screen. the said hole thus indicating the position of the hit. though the invention may be employed in conjunction with any other suitable form of target. Such a""s'creen forms the subject of a prior Patent No.1,027,371 granted to Benjamin \Villiam Batesand A. T. C.Hale, the screen being so constructed that a puncture made by the shot may be readily obliterated.

0f the various embodiments of which the invention is capable we have selected for illustration a specific embodiment, the structure of which at the present time we con sider to exhibit the different features of the invention in the most convenient manner and effective form.

In the accompanying drawings :-Figure l is a diagrammatic View showing the various parts ofthe apparatus with their electrical connections. Fig. 2 is a side elevation of the breaking or motion arresting device carried by ihe kinematograph. Fig. 3 is a side elevation with beater shaft broken at A-B. on Fig. 4 thus showing spring controlled stop. Fig. 4 is a plan, while Fig. 5 is a plan showing the arrangement for operating the screen.

In carryin our invention into practice as shown upon t 1e accompanying drawings, on the beater shaft 1 of the kinematograph we provide a brake drum 2, which might be provided on another shaft; underneath said brake drum are arranged two electromagnets 3 having an armature 4 pivoted in a suitable Specification of Letters Patent.

bracket and normally held out of contact with the magnets 3 by a spring 4. Around the brake drum 2 is a band brake?) one end of same being attached to a suitable fixed point and the other end attached to the armature 4 so that when the uiagnetsare energized the band 5 is drawn ti ht around the brake drum 2. It is well moon that the lnovement of kiiieinatograph pictui esii'sihterinittent. and the objectiof th e following contact device is to make it impossible for the'stopping circuit to be completed. whiletlieifilms moving, and thus to prevent the possibil-' ity of a picture being half on the screenit being essential that the; kinematograph should only be stopped when a complete picture is exposed." To insure this we employ a wipe contact 6 on the brake drum 2 and contact 7 these contacts being inthe same circuit as the magnets 3. The circuit containing themagnets3 can only be completed when the wipe contact 3 is in contact with the spring contact 7 thereby energizing the magnets 3' and applying the handbrake 5 to the drum 2 and thus stopping the machine without shock. The wipe contact (3 being at a particular point on the drum and in a particular relation to the heaters it insures that the circuit can only be completed and the kinematograph stopped when a full picture is exposed.

To insure the kinematograph stopping at the correct place in the event of the wipe cont-act 6 over-running the spring contact 7 before the kinematograph is completely stopped, we provide a pillar contact 8which is in the same circuit as the magnets3 and 10. The pivoted armature 4 is preferably provided with a spring contact 9 which is so arranged that when the armature 4 is in its normal position the spring contact 9 is slightly out of contact with the pillar contact 8. Should the contacts 6 and 7 be broken before the kinematograph is properly stopped. the slight movement of the armature 4 which it would have in the event of the contacts 6 and 7 only momentarily engaging each other, would cause the spring contact 9 to engage the pillar contact 8 thereby completing the circuit and stopping the kinematograph in manner hereinafterexplained.

As a further safeguard for stopping the kinematograpb we preferably provide two magnets in the same circuit as the magnets 3 and provided with a pivoted armature 11, so arranged that at the same time as the magnets 3 are energized the magnets 10 are also energized thereby drawing down the armature 11, the end of same being so arranged that if the hand brake 5 is unable to take up the momentum of the machine in time, a sure stop is provided in the correct place by means of the end of the armafture 11 abutting against a spring controlled stop 13 on the drum thereby stopping the machine without shock. On the beater shaft 1 is also provided a' suitable friction or other clutch, the one shown being of the electromagnetic type. The part 12 is driven by an electric motor or any other suitable means employed for driving the machine. Theclutch is so'arranged that when the film is running the coil of said'cl'utch is in circuit thereby energizing the magnet and driving the part'13 which is keyed to the I the sound waves, said microphone being connected by the wires 15 to the primary of the transformer 16, a battery or other source of energy 17 supplying the current for this circuit. 'The microphone is preferably located in a conical sound receiver.

It will be obvious that the variations or vibrations of the current in the primary circuit are extremely feeble being the nature of those used in telephony and it is therefore essential that the relay shall be of an extremely sensitive construction in order to respond to thesefeeble currents. A suit able form of relay forms the subject of a prior application for a patent- Serial No. 690.194 of Hans Von Kramer and Doctor Gisbert Kapp. Such relays are of the pol-' arized type and employ a steel reed having its vibrating end located between the ex tremities of the polar extension around which'wire forming-part of the controlling circuit is wound. These windings may form part of thecirciiit which the microphone is located or as stated they may form part of the secondary circuit of an induction coil'or transformer or they maybe otherwise influenced by the circuit in which the microphone is located.

The mechanism may be so arranged as to respond only to the sound waves above a certain predetermined periodicity and in certain circumstances to respond to sound waves of a known periodicity which is effected by tuning the vibratoryi'red to correspond with the vibrations of the microphone diaphragm set up by the sound waves in question Connected to the secondary of the transformerlG is a relay 18 said relay being of the kind described in Kramer and Kapp specification Serial No. 690,194. On the vibration of the diaphragm of the microphone 14 a-vibrating current is set up in the primary of the transformer 16 thereby inducing a vibrating current in the relay 18. 18are provided with contact pieces 20 so arranged that when the armature 21 of the relay vibrates a circuit which will be hereinafter described is broken by the contacts v2O being separated.

Connected to the contact springs 1t) are wires 22 and battery 23 which is also connected to the relaymagnet 24. Normally gized thereb position an keeps the magnetic clutch energized in manner hereinafter described;

On an induced current being set u ni the transformer 16 the relay 18 is energized mentarily deenergi zing the 'relay 24, the

armature 25 then dropping under the im fluenceof the spring 26 and completing another two circuits through the contacts 27 and 28, thereby energizing the magnet 29 which holds the armature 25 on the contacts 27, 28, and also energizing the solenoid 49 as hereinafter explained.

The magnet 29 is energized in the followi manner :Current is taken from the b ttery 30 along wires 31, 32, frame 33 of the relay 24, armature 25, .contact 28,

through the coil of the magnet 29, wire 34' spring contacts 35, 36 Wires 37, 38, and back to battery 30.

When the armature 25 is in its normal or raised position it is in contact withstop 39 thereby completing a circuitand energizing the magnetic clutch. The circuit for normally holding the clutch in engagement is as follows :-battery 30, wires 31, 32, frame 33 of relay 24, armature 25, contact 39, wire 40, contact 41, movable contact 42, wire 43, wipe contact 44, annular ring 45 which is insulated from the part 12 by means of insulation 46. The one end of the coil in the clutch is connected to the 'ring 45, the o her The flanking springs 19 of the relay .the coils of the relay magnet 24 are enerthereby breaking thecontacts, 20 and motrue 25 disengaging the stop 39 the circuit is broken thereby d energizing the magnet of the clutch and allowing the part/12 to run free. At the same time as the armature 25 cpmes in contact with the stops 27, and

28 the magnets 3 and are energized through the wit-e47 thereby drawing the armatures 4 and 11 into their attractedition applying the hand brake 5 to the 2 and stopping the machine. The circuit for energizing the magnets 3 and 10 is as follows :When the contact 28 is engaged,

by the armature 25, the current passes from battery 30, wires 31, 32, frame 33, of relay 10 24, relay armature 25,-contact 28, wire 17,

and. wipe contact 6' then t 'chine which is earthed, wire 48-to batterythrough coils 3 and- -10 ;-spring coxliltact 7 rough t e ms 30. In the event of the contacts-6 and 7 being broken before thekinematograph is from the battery 30, along Wires 31', 32, frame 33 of" relay 34, relay armature 25,

7 wire 48 to battery stopped, the aforesaid circuit is momentarily completed thereby givingthe armature 4 apartialmovement and engaging the contacts 8 and 9 and completing the circuit for stopto ping the machine in the correct place in the ollowing manherf-(The current would pass the prior Patent 'No. 1,027,371 wherein two' sheets "of -perforated paper are employed,

1 relativejmovement between the ;two sheets serves to l close the '-'puncture" and obliterate the effect of the shot. This relative mmment=*'is automhtically efi'ected' simultane' ously with the restarting of thepicture proiecting devices-"3 Y On the'falling of the armature 25 a ther circuit through contact 27 is completed whereinthe solenoid 49 is energized thereby lifting up the movable core 50, said core being controlled in its movement by a dash pot 51 or any other suitable device. On the core 50 rising the circuit controlling the magnetic clutch is broken by the movable contact 42, disengaging from the contacts 41, and remainsbroken until the return of the core 50 .replaces contact 42, the member 12 beingt-hen allowed to continue running while the other part of the picture projecting device is stopped. The core 50 still continuing its upwardmovement completes a further circuitto actuate, the screen, the 'circuit for operatinr the screen being as follows :-The core 50 has risen' until the movable contact42'hascompleted the circuit by engaging-the contacts 53. The current 15 taken from the battery 30 along the wire 31, contacts 53 movable contact 42, wi're'52, to solenoid 54, thereb actuating-the armature 55. Theend of t e armature 55 is-1n the form of a free wheel clutch *5? mounted on the shaft .63 so arranged that on the solethe paper too freelyunwinding.

noids 54 being energized the armature 55 is drawn down thereby rotating the pinion wheel Gtwhich engages a further ear wheel 65 carried by the shaft 68, said 3 aft 68 is connected to the store roll 58, all being so arranged that when the solenoids 54 are energized the armature 55 is drawn downward and the shaft 63 rotated thereb driving the gear wheel 65 through the pimon 64 and 1 rotating the store rol 58-and thereby obliterating the shot holes. When the solenoids 54.- are denergized the armature 55 returns to its original position-under the action of the spring 69, the clutch 54 having a free movement on its return. The pawl 66 engages. the tooth wheel 67 and prevents backward rotation of the store roll 58. By this means the shot holes areobliterated in manner described in the prior patent of Benjamin William Bates and A. T. C. Hale No. 1,027,371. Around part of the su ply roll of the screen we arrange a. suitab e hand brake so as to On the core 50'reaching the top the solenoid 49, it engages a. plunger 60 there prevent by breaking the contacts 35, 36 deenergizing the magnet 29f-and allowing the armature 25 toreturn to its nonnal position thereby completing the circuit for energizing the magnetic clutch and restarting the picture projectingmppara-tus. ready for. 'a further shot. to be tired on the'return of the core 50 and contact 42. V in A The duratiton of the time for which the machine is stopped is controlled by a dash pot 51 only allowing the core to rise slowly andbreak contacts 35, 36, the return being practicallyinstantaneous, as the piston (31 1s prmided with a one way valve 62. A suitable time for stopping is about three seconds but this may obx'iously be varied as required.
