Specification of Letters Patent.
Patented June 27, 1916.
Application filed March 2, 1914. Serial No. 821,879.
To all whom it may concern Be it known that I, GEORGE Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented cera moving picture is projected upon a perforable screen, in the rear of. which is a source of illumination, so that that portion ofthe screen pierced by a projectile will be indicated by the light shining through.
.It is desirable that the moment the projectile pierces .the target the machine for projecting the picture be stopped so that the proper relative positions of the object at which the marksman aims and the pierced part of the screen be truly disclosed. T
have provided'means in connection with a ,fire-arm whereby thestopping of the projecting machine will be accomplished by means controlled by the movement of the hammer, and I have further provided means whereby the hammer can be cocked or drawn back ready for firing without in any way affecting the controlling apparatus, the controlling being accomplished by the cartridge exploding movement of the hammer.
In the drawings: Figure 1 is a diagrammatic view of a picture projecting apparatus, a target with its screens and light source, the circuits for controlling thetarget screens and the picture projecting appa'ratus; Fig. 2 is a view partly in section and partly in elevation of a clutch mech anism useful in connection with the projecting apparatus, the specific form of clutch forming part of an application previously filed by me; Fig. 3 is a longitudinal sectional view througha gun stock to which the circuit breaker included in my invention is applied; Fig. 4 is an enlarged ele- Q vational view of the circuit breaker in the position the parts will assume when the hammer isdown on the firing pm; Fig. 5
is a similar view showing the moving contact of the circuit breaker moving into operating position; Fig. 6 is a similar view showing the movable contact ready to operate, and the position .which it will assume A. KEREsTEs, a' citizen of the United States, residing at of the conductors 34 and 35 receiving elec when the hammer is drawn back ready to breaker; Fig. 8 is a sectional view on the fire; Fig. 7 is a top view of the circuit line 8-8 of Fig. 4; Fig. 9 is a sectional view on the line 99 of Fig. 6; and Fig.
10 is an end View of the gun stock with the guard plate removed.
The driven shaft 1 of the moving picture machine 2 carries a clutch member 3 fast to the shaft, and it isprovided with a toothed face 4: adapted to engage a similar face 5 on the complementary clutch mem her 6 loose on the shaft 1', and which may or may not be a part of the drive pulley 7 to which it is secured.
interposed between an abutment or shoulder 8 on the shaft 1 and the pulleyv 7 is a spring 9 coiled around the shaft 1, the tendency of which is to maintain the members 3 and '6 in clutched engagement. The clutch .member 3 is provided with a plurality of radial recesses 10 corresponding in number with the number of vibrations of the shutter per second (in the present instance there are sixteen).
One face of the clutch member 6 is pro vided with a spiral groove 11. The clutchactuator is shown as consisting of the levers12 and 13 pivoted at their lower ends to'suitable supports 14 and 15 and at their upper ends to the levers 16 and 17 which are secured to a "pivot pin 18, the part-s being suitably supported, Fig. 1 indicating one' form in which this support may be provided. On the lever 13 is a recess engaging finger 19 to engage in the recesses 10 in member 3. Anti-friction devices 20 are carried by the levers to engagethe spiral groove '11 on the clutch member 6. The clutch actuator is provided with a link 21 connected to an operating lever 22, pivoted at 23, and connected to the core 21 of the solenoid 25. The solenoid 25 is connected to the mainline wires 26 and 27 of a suitable source of supply through the medium of the wires 28 and 29, said circuits being adapted to be broken, however, by the bridge contact 30 moving out of engagement with the spring contacts 31 and 32.
of which is connected. to said bridge contact 30 and the circuit for which consists 25 I the inner screen 54 being driven from the The circuit for the solenoid 33 may be controlled by suitable mechanism within or on the fire-arm, and which will be morev specifically described hereinafter. The circuit consisting of the wires 28 and 29 may be broken by the solenoid 37 connected to the bridge contact 30 by a flexible connection 38, the circuit for the solenoid 37 being here shown as consisting of the conductors 39 and 40 supplied with energy by a battery 41. On the core 24 of the solenoid'25 is a member 42 adapted to close the circuit between contacts 43 and 43 while the solenoid is energized.
44 is a contact onthe operating lever 22 which, when the core 24 is being moved inward by the energizing of solenoid 25, will move past the insulation 45, but which on the return movement will contact with a contact 46 so as to close the circuit consisting of the wires 47 and 48 one of which is connected to the mainline and which operates a solenoid 49 connected to a pawl 50 engaging ratchet 51 on the rotating shaft 52 around which the outer screen 53 passes,
shaft 52 at a different speed from the outer screen. It will be apparent that when motion is imparted to the shaft 52 any holes in the twoscreens which are in register will be staggered so that the light from the box 55 of the target will be excluded.
56 is a spring connected toi 'the. pawl and opposed to the solenoid 49.
\ It will be apparent that if the circuit consisting of the wires 34 and isclosed that the solenoid 33 will be energized. That the energization of the circuit consisting of the P wires 34 and 35 will be efiective in causing the bridge contact 30 to close the circuit consisting of the- wires 28 and 29, so as to cause the operating lever 22 to force the lever 13 with its finger between the two clutch devices and throw the clutch finger 19 into the recess 10 so as to prevent the. shaft 1 of the machine from rotating.
- The movement of the anti-frictionmembers across the face of the member 6 will-force the clutch teeth members 4 and 5 out of engagement, whereby themember -3 will be held rigid by finger 19, but member 6' will continue to rotate, however, inasmuch as it is loose on the shaft. Its continued rotation broken, because the flexible connection 38 attached to the contact 30 will cause the contact 30 to move away from the contacts cient to impart a rotary movement to the roller 52 so as to move the outer screen 53 and thereby stagger the perforations in the screens53 and 54 as previously described.
As will be readily understood, this general ar-' rangement provides a timing element in the operation. While solenoid 33 is momentarily energized when the hammer drops on to the cartridge, solenoid 37 breaking the circuit of solenoid 25 as soon as core 24 reaches its inward position, and thus retaining the various circuits active momentarily, the period of time (hiring which the screens remain stationary and the effect of a shot ascertained is controlled by the mechanical means shown in Fig. 2, the latter controlling the length of time during which the cine-' matograph remains stationary, and the screens held from their relative movements. Consequently, the timing element is mechanical in operation, being brought into activity through electrical means and in turn acting to shift the screens as presently described. The initial circuit, of course, is
that consistingof the wires 34 and 35 with its battery 36. The closing of this circuit 'sets all theother circuits in operation in their proper order, so" I have provided means controllable by a fire a'rm which will momentarily close the primary circuit so .that the mechanisms controlled by the remaining circuits will be set in operation and so that the act of stopping the picture machine will be coincident with the discharge of the fire-arm. The mechanism for effect ing the closing of the circuit is illustrated in detail in Figs. 4 to 10 both inclusive. I
Referring now more particularly'to Figs. 3 and 10, 56 designates the stock of the firearm, in the present instance arifle, between the heel and toe of which is a recess 57 covered by the guard plate 58. In the recess 57 is a plate 59 receiving the wire 35 which enters through the channel 60 in the gun stock, and the plate 61 receives the wire 34 through the same channel-60. From the plates 59 and 61, the wires 34 and 35 continue to the lock case through the longitudinal channel 62. The lock case 63 contains the usual operating mechanism for the hammer 64, its trigger 65 and the operating spring 66, these all being of any approved construction. Within the lock case, I provide a mechanism supporting block 67 which may consist of pressed fiber or other suitable insulating material. The block 67 is substantially rectangular except that one corner is cut away to provide for the movement of the hammer operating spring 66, and the block is provided with a cut out portion or recess 68 in which the fixed contacts and movable contact are located. Pivoted to one side of the block 67 is a substantially rectangular plate 69 of good electrical con: ductivity, said plate being pivoted to the block 67 at 70, and provided with an elongated recess 7l.through which a pin 72 from the block 67 projects. The plate 69 carries a segmental'contact block 73 having a contact face 74 of conducting material which is connected to the plate 69, the block 73 being of suitable insulating material. The contact face 74 is inclined but substantially parallel'with the spring contact 75 which is say, the members 74 and 75 constitute what cent to the block 67 and one branch 34 is connected to the pin so that current can be conducted through it to the plate 69, and the other split portion 34 is connected to the binding post 76 of the contact 75. The wire 35 is connected to a binding post 77 carrying a swinging link 78 provided with an elongated slot 79 in which is slidably secured the movable contact pin 80 connected to a movable part of the firearm, in the present instance the hammer 64, by the actuating link 81. 83is a flat spring connected to the block 67 by the fastening device 83, said spring being positioned adjacent to the end of the block 73 so that the return move ment of the movable contact 80 willbe retarded as will be explained hereinafter.
Assuming all the parts to be properly assembled, and the hammer down on the firing .pin, the parts will be in the position shown in Fig. 4. When the operator cocks the hammer, that is, pulls it back toward the butt of the gun,,the link 81 will move the movable contact 80 in the slot 84, as
shown in Fig. 5, until the hammer is drawn .might properly be termed a split contact because the conductor wire 34 is split adjaplate 69 which carries it, the circuit consist' ing of the wires 34 and 35 will notbe closed because the sides ofthe block 67 are of insulating material as well as the block73, and the pin 80 is of less length than the thickness of the block 67,'so the pin 8 0'will not come in contact with the plate 59 or any other conducting element. When the contact pin 81 is in the recess 85 of the slot, the fire-arm is ready to be fired, and as the plate 69 is a gravitated plate, the pin 80 will have moved under the block 73 raising it, as shown in Fig. 5, the plate droppingback when the pin has passed block 73 and rests in the recess 85, the position shownin Fig.- 6 or in its original position as shown in Fig. 4. When the hammer moves forward, it carries the pin 80 withit, and inasmuch as the plate 67 and'the block 73 have as- 7 sumed the position shown in Figs. 4 and 6, it is obvious that the pin must be guided between the contacts 74 and assuming, as it passes between the contacts 74 and 75, the position shown in dotted lines in Fig. 6. 75' There will be a momentary contact between pin and'contacts 74- and 75 because the spring 66 will be strong enough to drive the hammer down on the firing pin instantane-v ously. The momentary contact, however, 80 will enable the current to How from the battery 36 through conductor 34, solenoid 33, branch 34, pin 70, plate 69, to contact 74, and through branch 34" to-contact 75, re-. turning to battery 36 through contact 80 and lead 35. The movement of the contact 80 from the contacts 74 and 75 will cause the contact 80 to strike the spring 83. which will cause it to rebound and be guided into the slOt 84 so that it assumes the position shown in Fig. 4 ready to be moved down through the slot 84 into the recess 85 and in position to again close the circuit as has been previously explained. The instantaneous closing of the circuit coincident with the movement of the be energized to break the primary circuit.
As the picture machine is stopped, the operation of the solenoids 33, 25 and 37 follow in such rapid sequence as to be almost instantaneous, indeed the operation of the solenoids 33 and 25 and the retarding mechanism for the moving picture machine being to all intents and purposes so absolutely instantaneous that the picture projected on the screen at the time the projectile passes therethrough will remain during such time that the machine is stopped, so that the actual position of the picture at the time the projectile pierced the screen can be observed by the marksman.
.From the foregoing description, it will be seenrthat the projecting machine is under the control of the marksman, and that the hammer on :the fire-arm and that the movement of the hammer toward the firing pin Will be effective in actuating mechanism which will cause the projecting machine to cease operating. In its broad aspect, the circuit closer may be used, in other connections than herein shown.
