' useful Improvements in Moving-Picture Indicators, of which the'following is a specification.

This invention has relation to time controlled programs for moving picture theators and has for an object to provide a device having a clock face and a hand movable the i eacross to indicate the title of the picture being projected at any time, the length'o'f the picture and the rate at which the picture is being shown. a

Another-object-of the invention is to provide a time controlled program for moving picture theaters including a dial adapted to support signed inserts to indicate the title of the picture shown in each show, and figures denoting the passage of time, with a movable hand and clockwork mechanism therefor to .move the hand across the dial whereby to indicate the title of the picture shown at any instant, the length of the particular picture being shown, and the rate at which the show is progressing.

A still further object of the invention is to provide a timecontrolled program for 1noving picture theaters Having the characteristics above described with electrically operable means for permitting the program to be started or stopped and to begin an actuation of the indicating program with each show. a

A still further object of the invention is to provide a time controlled programfor moving picture theaters of the natureeabove described, including a dial adapted to support a series of inserts each insert indicating the title of the picture whereby the insert of one member of the series may be spaced difierently from the inserts of the next series, with a time controlled movable hand to sweep across the face of the dial whereby the rate" at which the pictures are being shown at any time during the day and night may be observed.

In addition to the foregoing my nvention comprehends improvements in the details of construction and arrangement of the parts to be hereinafter more. fully described and particularly set forth in the appended claims.

1; In the accompanyingdrawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they' appear:

Figure 1, is a view in front elevation of a time controlled program for moving picture machines constructed in accordance with my invention.

Fig. 2, is a view thereof in side elevation with the casing broken away to illustrate the mechanism interiorly thereof.

Fig. 3, is a detail section taken through the center of an actuating solenoid.

Fig. 4, is a detail view of the governor regulating means and brake, and

Fig. 5, is a view in front elevation of a modified form of my invention.

NVith reference to the drawings, 10 indicates a casing having a dial 11 mounted at the front 'end thereof, said dial having a. pair of concentric circles 12'and 13 inscribed thereon, the space between the periphery of the dial and the circle 12 being divided bygraduations designated by numerals 14 to indicate hours and minutes of time, the space between the lines 12 and 13, being adapted to receive inserts 15 in the nature of small signs having printed thereon the title of each picture or the nature of the picture to be exhibited in each show. An insert 16 is also provided having the word End printed thereon located at a distance from the starting point of the graduations 14 to a point on the graduations corresponding to the durationof the show as for instance Two hours and one-half.

An opening is formed centrally of the dial to receive an arbocllwhichsis formed with a section 18 and a section 19in alinement, the section '18 extending at one end through the dial and having a recess 20 at.

is mounted upon said section 18 Within the casing. A flexible element 25 is pased around the drum with its inner end Secured thereto, the opposite end of the element supporting a weight 26. A lug 27 is secured to the section 18 and is designed to engage a lug 28 mounted on the frame whereby to limit movement of the section 18 when the flexible element unwiuds under the influence of the weight :26 to return the said section 18 of the shaft to original or starting position. The section 1!) is journaled for rotative and sliding movement in a bearing 25.) uounted on the side wall of the casing. anu supports a circular or disklike armature 30 of soft iron which is to be attracted by an electromagiu-t 31 which encircles the arbor 17. A shrouded pinion 32 is mounted on the section 19 of the arbor for engagement with a pinion 33 mounted upon an arbor 34 which is supported at opposite ends upon a bifurcated bracket- The arbor 3+ is designed for rotative and longitudinal sliding movement in the bracket, and carries at one end a penetrat-ive member 36 of a cone clutch. the

respective member thereof being indicated at 37 and mounted upon an arbor 38 in alinement with the arbor 34 mounted in a bracket 39. v

A relatively large gear 40 is mounted upon the arbor 38 for driving a relatively small pinion 41 on an arbor 42, which also carries a relatively large gear 43 for meshing with a relatively small pinion Hmounted upon an arbor 45.. Said arbor 45 carries a relatively large pinion to for meshing engagement with a relatively small pinion 47 mounted upon an arbor 48 which also carries a bevel gear 49. A relatively.small bevel gear 50 mounted upon an arbor 51 is in meshing engagement with the bevel gear 49, said arbor 51 carrying a relatively large pinion 52 for meshing engagement with a relatively small pinion 53 upon a vertical arbor 54. A worm wheel 55 is mounted upon said arbor 54 for engagement with a worm 56 mounted on a governor shaft 57' which carries a governor which comprising weighted spring members secured to one end of the shaft and adapted to slide a disk 58 whentbe springs are separated or moved together during rotation of the shaft. A lever the disk. said lever being fulcrumed at 60 and having anadjusting screw 61 to bear against the opposite-end of the lever whereby the speed of the governor shaft may be regulated. A shaft 62'is journaled near the terminal of said lever 59 with one end bent at right angles as at 68 to form a handle,

and a cam 64 provided upon its upper end to engage the'le'ver 59 whereby when the shaft 62 is rotated the lever 59 may be moved to jam the tabsaga-instthe disk 58 and thereby form a brake to arrest motion of the mechanism.

The arbor 54 carries a bevel gear G5 whieh is in meshing engagement with a bevel gear ".66. mounted upon a horizontal shaft 67. The

59 carries tabs to engage the face of line 80,

shaft 7 is then connected by means of a train of gearing indicated generally at 68 to the gear (39 ot' a spring drum 70 mounted upon a bracket 71. A ratchet wheel 72 is mounted to rotate with the arbor of the. spring drum and a spring held pawl 72 engages the ratchet to retain the spring under tension. 'A winding arbor i3 is journaled in the bracket 71 which carries a pinion H fol engagement with the gear 69. a handle 7 being provided to rotate the windi..g arbor whereby to place the spring within the spring drum under tension.

'hen the brake of the governor is releasedthe rotation of the spring drum is transmitted through the gear 69 thereof and a train of gears 68 to the arbor (i7, and thence through the gears (36. 65. 53, 52. 50. 45), 47, -16, 44, 43, 41. and 40 to the arbor 38. the rota tion thereof-being transmitted through the clutch members so and 37 to the arbor 2-H and thence through the gears I33 aml 32 to the arbor 17 thereby moving the pointer 23 across the face of the dial at a speed which is controlled by the governor. The moving 0 picture projecting machine is operated at the same time the governor being adjusted to correspond to the speed of the projecting machine so thatthe pointer will imlicate the amount of the reel still to be shown before. the terminal is reached. ()ne reel after another is shown. allowing a few minutes for the exchange. of reels until the pointer reaches the insert 16 indicating the end of the show. whereupon the elect-ni-magnet 31 is energized by depressing a button To which is in a circuit 77 including the electromagnet and a source of current 78 whereupon the armature 30 is attracted and the section 19 of the shaft 17 thus 'moved longi- 5 tudinallv. Owing to the provision of the shrouded pinion 312 its connection with the pinion 33 is such as to shift the arbor 2H and thereby disengage the clutch members so and 37. The connection between the shaft 17 and the spring operated mechanism is thus broken and theweight 26 is freed to rotate the shaft 17 and thereby return the pointer 23 to initial position, its movenumt'being limited by the stops 27 and 28. When the. electro-magnet is deelnelgized the spring 22 within the shaft 17 acts to return the clutch members 36 and 37 to engagement and the foregoing operation is; repeated.

I have illustrated in Fig. 5'of the drawings a modified form of my invention which includes a dial 79 having circles 80. 81 and 82 inscribed thereon in concentric relation. the lines defining therebetween circular areas in which inserts 83 are placed, the areas being also divided up by graduations to disappear at times. A pointer 84 is provided to sweep across the face of the dial. The areas between the periphery of the dial and the between the lines 80 and 81 and be- 1 0 1 lamp within the casing 87 for instance, ac-

V tween the lines 81 and 82 are indicated respectively by the characters A, B and C. A

plurality of casings 85, 86 and 87 are mount ed'adjacent the dial, each casing having a transparent cover with one of the characters A, B, and Ginscribed thereon, and incandescent globes 88 disposed therein. One terminal 0 each globe is connected to a common return wire 89 having a source of cur- ;rent 90 interposed therein, the other terminal of the those in the area B, and those in the area CL may be spaced variously relative to the spacing of theother two sets of the series.

' n the use of this form of my invention, the inserts of one member of the series are utilized at a time. In the conduct of moving picture shows it is customary to exhibit the pictures at difierent rates of speed according to the time of the day. For instance, in the early hours of the day the pictures are shown at a lower rate of speed than thosev shown in the afternoon when the attendance is larger than in the earlier hours. In the evening the. speed of production is still further increased. Therefore, when the rate of projection of the picture is to be slow the cording to the arrangement disclosed. in

Fig. 5 is illuminated and the patron by 6b: serving this will read the .position of the' pointer 84 relative to the insert or gradu-a- 1 tion within the area C on the dial 79. Conversely, during the evening when the pictures are projected at a greater rate of speed, the lamp within the casing 86 is illuminated thereby indicatingthat the hand of the dial is to be read in connection with the inserts within the annular space of the dial. Thus it will be seen that I have provided a device of a new and novel character which may be located in front'of a moving picture theater and thus inform prospective patrons the exact condition, the rate at which the show is progressing, and exactly which picture is being shown at that time, as well as the extent to which the picture has been shown. and the period of time to elapse before the end thereof. The machine is furthermore simple in its nature comprising few parts, thereby insuring positive action and permitting the manufacture of the machine at a low cost. Y

While I have illustrated and described my invention'with some degree of particularity,

. V I realize that in practice various alterations thereover maybe made, and I therefore desire to reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the correlative parts without departing from the spirit of the invention or the scope of the appended claims.
