Falkenberg, Chicago, lil., assigner to Rayolite Rifle Range Company, Chicago, Ill., a corporation of Oklahoma Application January 11, 1937, Serial No. 120,046 1 Claim. (o1. 27s-101.1) My invention relates to an improvement in electric target rifle ranges of the type in which an aimable member ñres a flash o_f light at a target which may include a photoelectric or light sen r, sitive element. One purpose is the provision of an improved target riñe range of the type described in which the target includes a movable base target portion and an apertured target drop portion. xo Another purpose is the provision of an im proved target drop and an improved means for maintaining it normally upright, and for releas ing or moving it to depressed position in re sponse to -a hit. lo Another purpose. is the provision of improved ing sleeves l5. Mounted in said bearing sleeves |5 are any suitable shafts IG which receive pulleys |'| about 15 wiring means and control means for such a de which passes the belt I8 which may be of the V belt type. I9 is a drive pulley on one of the said shafts which may be driven by means of a belt 20 Another purpose is the provision of an im in the course of the specification and claim. I illustrate my invention more or less dia grammatically in the accompanying drawings wherein: Figure 1 is a front elevation; Figure 2 is a -section on an enlarged scale along the line 2_2 of Figure 1; Figure 3 is a front elevation of the target struc ture proper; Figure 5- is a- section on the line 5_5 of Fig ure 4; Figure 6 is a section on the line 6--6 of Fig 35 ure 4; from the motor drive pulley 2| associated with the motor 22 herein shown as positioned in the aperture I3. Any suitable gear reduction struc ture may be interposed between the pulley 2| and the motor. vIt will be understood that when the motor 22 »is energized the pulleys Il rotate and cause the belt I8 to move in the direction indi cated by the arrow in Figure 3. 23, 24 indicate tracks which include horizontal parallel portions 25 and end portions 26 generally 25 concentric with the axes of rotation of the pulleys Figure 4 is' a top plan view of the structure shown in Figure 3; ' Figure 7 is a section on the line '|-'l of Fig ure 4; i Figure 8 is a section on the line 8--8 of Fig ure 3; 40 panel whereby the panel is normally in upright position. The panel is provided with an aper ture |3, the purpose of which will later appear. The panel II may be of metal and is herein shown as provided With forwardly projecting bosses I4 to which the later described structure is mounted, and also forwardly projecting bear vice. proved score indicating means for such a device. 20 Other purposes will appear from time to time 3() I illustrate any suitable cross pieces or sup ports 8 Within the cabinet I which may be pro vided with bearing sleeves 9 which in turn receive bearing pins II) mounted on any suitable panel 1|. I2 beingl means for holding the upper end of said Figure 9 is a section on the line‘S-B of Fig ure 3; and Figures 10 and ll, taken together, constitute a wiring diagram. Like parts are indicated by like symbols 4:, throughout the specification and drawings. Referring to the drawings, I indicates any suit able cabinet having downwardly extending sup ports 2 and a removable front panel 3. The said front panel has‘an upper aperture 4 which may 50 be closed by a pane of glass or equivalent mem ber 5. A lower aperture 6 is closed by a pane of glass 'I which is herein shown as having indi cating numbers or signals thereon from zero to ten, as shown in Figure 1, the purpose of which 55 will later appear. Il. These tracks'may be mounted in any suit able fashion as by plates 2l which may be con 30 nected together by the cross pieces 28, the inner plates being secured to the bosses |4 as by any suitable screws 29. Mounted for movement along the said tracks are carriages generally indicated 85 as 30, each such carriage having pairs of wheels or rollers 3| engaging the outer track surfaces and pairs of wheels or rollers 32 engaging the inner track surfaces, the distance -separating the axes of the outer rollers being slightly greater than that separating the inner, to permit the car riage to move readily around the arcuate portions of the track. ’I'he carriages 30 may include an upper platform 33, upon which is mounted a photo'electric cell 34 herein shown as provided 45 with a forward chamber 35 which may be clo‘sed by the lens 36 the purpose of which is to con centrate light upon the cell 34. The rest of the cell 34 may be painted black or otherwise ob scured or, if desired, may be surrounded by a 50 housing, in order that the cell may be protected from any light except that which passes through the lens 36. Pivoted to the carriage 30 is any suitable target drop member 3l herein indicated as in the form 55 2,15e,141 y 2 and may remain illuminated to indicate the score of a duck and provided with an aperture 38 which, until the device is prepared for an ensuing user when the target drop portion is in upright posi by the insertiony of a coin and the closure ofthe tion, is positioned forwardly of and alined with the lens 36. >The target drop portion 31 may be coin switch 56. .

Referring to Figure 11, I illus trate the gun generally indicated as 5i which is provided with a lamp bulb or light source 52, the circuitl forwhich will later be-de'scribed. It is wheel 60 -one'step. The spring‘liß` returns the armature 66 to the full line position’as soon as the energization of the magnet 65 terminates.

This causes the arma ture `16 to »move to the right, referring to the e position of the parts in which they are shown in 60 Figure 6.v This in turn rotates the trigger mem -ber generally indicated as 11. The upper member or» bar 18.then strikes thegdownward extensions 40 of the target drop, frees the target drop from the Asprings 4i „and causes it .tofall forward into the dotted line position in which itis `shown in 'Figure 6.

' x u „ , ,. A hit, in addition to causingthe duck to fall , 2,159,141 3 and the chime to sound, operates the scoring with the cross pieces 28. Opposed to the tracks device. I illustrate, for example, on any suitable base 85 a series of individual iixed contacts 86, 86a, etc., which are insulated from each other. Opposed to them is a moving switch arm 61 piv oted as at 88 and operated by the ratchet wheel 91l are contact rollers 99 which may be mounted on springs |00 associated with the carriages or bases 30. They may be mounted on insulating blocks or members |02. The track 91 provides one connection for the cell and the other connec l 89 which is normally urged in counterclockwise tion may be obtained as by grounding on the car rotation by the spring 90, the structure being riage structure. The indicating lamps |0|, |0|a, etc., may be generally similar to the limit switch structure 1.0 above described. 9| indicates an electromagnet which is energized at each hit. When energized, it moves the armature 92 in such fashion as to cause the dog 93 to move the ratchet wheel 69 mounted on a frame |03 which is divided into l0 one step. Retrograde movement of the ratchet' compartments by walls |04. The frame |03 may be mounted upon the panel, for example, by arms |05. Referring to the wiring diagram of Figures 10 15 wheel is prevented by the detent 94 which is held and 11, a source of outside 110 volt current is in in operative position by the spring Q5 unless and until it is withdrawn by the energization of the reset magnet 96. Both the shot limit mechanism and scoring device above referred to may be20 enclosed in housings 51a and 65a, respectively, and may be mounted upon the panel ||. The operation of the device may be summarized as follows. When the operator inserts a coin and closes the switch 56, the reset magnets 64 and ' 96 are energized and both the shot limit switch and the scoring switch are returned to the initial o1' dotted line positions in which they are shown dicated at ||5, ||6, although it will be understood is illustrated in Figure 1, as mounted at the bot tom of the cabinet I, and is visible through a lens |06. The lamp H8 is preferably mounted above the target structure to illuminate the scenery in Figure 11. At the same time, the motor 22 is energized and the targets begin to move. When the operator aims and pulls the trigger, 30 >and closes the switch 54, the result is an energi zation of the light 52 and the projection of` a brieiiy timed flash of light from the gun 5|.v 'I'he thud sounder 1| also sounds, simulating a shot or when energized, that the device- is in operation. _ , Electrically connected with the main power 35 the impact of a' bullet against the target. lines H5, I|6 is the primary winding |2| oi a The operator tries to hit the photo cell by hold ing his aim on the lens 36 which he sees through the aperture 38 of the target drop. If he is suc cessiul in hitting the photo cell, he energizes both 40 of the electromagnets 65 and 9|. The energiza tion of 65, which results each time thev trigger switch 54 is closed, merely uses up one shot by moving the arm 59 one step. The energization of the electromagnet 8| extingulshes the light 45 zero and illuminates the light I to the rear of the window aperture 6. In this connection, and associated with each of the contacts V|36, 66a, I may employ an incandescent lamp |0|, lllla, etc. -A' further result of a hit is the forward-fall of the 50 target drop member 3'! which indicates that the bird has been struck and the sounding of the chime 8|. After the operator has taken ten shots, the arm 59 breaks its contact with the contact 56> and 55 breaks the circuit for the motor 22, thus causing the targets to cease their motion. By a limit switch structure which will later be described, the targets continue to move until the upper target drop is centered midway between the ends of the 60 track, and all further movement then ceases. The scoring light remains illuminated to indicate «the total number of hits and the device is out of operation until the next ensuing operator in serts a coin and closes the switch 56. 65 It will be understood that I may employ a considerable variety of circuits in obtaining the above result and I do not wish to be limited to any speciñc circuit. I illustrate,- however, a prac tical and operative circuit which has actually been employed. In order to provide 'a connection between the cell 34 which is on a moving structure and the necessary ampliñer and fixed parts, I illustrate a Contact track member 91 which may be mount 75 ed on any suitable insulating blocks 96 associated 15S that any suitable voltage may be employed and the device may be operated on direct current. However, for convenience, I illustrate it in con nection with 110 volt alternating current. A manually controlled switch ||1 may be inter posed in one of the power lines whereby the en tire circuitl may be broken. Shunted across the main power lines' are the lamps l I6, ||9, which are controlled by the switch ||1. The lamp ||9 panels 49, 50 and the target drops 31. A pair of 80 colored lamps |20, |20 may be mounted at either side of the lamp l I6; its purpose being to indicate, power transformer T. A second transformer T' has one side of its primary winding |22 connected to the main power line ||5. The primary wind ing of the transformer T serves to energize the secondary windings |23, |24, |25 and |26. The 40 transformer T’ is provided with secondary wind ings |21, |28 and |29 of which the windings |26 and |29 are electrically connected with the recti fying units |30, |3| which in turn are connected in series by a line |32. The. secondary coil |21 45 is connected by lines |33, |34 to the plates of a rectifying tube |35 associated with any suitable photoelectric amplifier, indicated by A. The electrical circuit of the amplifier A is merely illus trated as an example, since several well known photoelectric circuits are suitable for the opera tion of my invention. For exempliiication, I have illustrated an am plifying tube |36, the grid element of which is connected by a line |31 to the rail 91 which in turn is engaged by the rollers 99 on the spring |00 associated with the target carriage 30. The spring is electrically connected to the anode of the photoelectric cell 34. In the drawings I have illustrated two target carriages 30, each of which carries a photoelec tric cell 34. Since only one target drop is visible at a time, an electrical rail 91 extending parallel with the upper edge of the rails 23, 24 may be employed as illustrated in Figure 5 or, if desired, it may be a continuous rail conforming to the contour of the rails. Referring back to the diagrams of Figures l0 and 11, the cathode of the photoelectric cell 34 is diagrammatically connected by a line with a ground connection |36. Likewise, the center tap of the secondary winding |21 of the transformer T’ is grounded as at |39. 'I'he secondary coil |23 of the transformer T supplies current to the filament of the amplify 4 2,159,141 . 'ing tube |36 through thelines |40,V |4|. 'I'he ’ indicating device 85, respectively, may now be secondary coil |24 is connected by the lines |42, .traced from the positive terminal of the rectifier |43 to the filament of the rectifyin‘gtube |35. |30, which is connected'in series with the rectifier The Vsecondary winding |25 of the transformer T |30, along the lines |84, |85, >|86 to the closed ' connects to a rectiñer"|44, the purpose 'offwhich - switch |13, thence >along the ~line |81, line |88r will later appear. »The end taps'of- secondary and shunt line |89 leadingvto the reset magnets 64' and 96 respectively, thence continues through the lines~ |90 land shunt line |9|, the common lines |10, |63, and lines |92, |93 tothe negative 1 winding |26 are provided with lines |45; |46 ot" which the line |45 extends to the switch arm 81 of the score indicator.
