Application filed March 10, 1898. Serial No. 673,348. (No model.)

To all whom it may concern:

' Beit known that I,THOMAS ARMAT,a citizen of the United States, residing at Washington, District of Columbia, have invented certain newand useful Improvements in Picture-Exhibiting Apparatuses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This'invention relates to improvements in appliances or apparatus for exhibiting pictures in successive progression so as to give them the appearance of persons or objectsin motion.

The objects are to provide a compact, efficient, and certainly-acting mechanism for the purposes intended which may be actuated by electrical circuits made by an interposed object, as a piece of metallic money, and broken at determined intervals or may be adapted to be actuated by applied mechanical means; to provide an improved mechanism for intermittently moving the film or band on which the pictures are imprinted so that the pictures shall be accurately and fully presented for visual observation; to provide a casing or receptaclefor the used or discharged picture film or band, from which it is drawn and carried in subsequent operations of the apparatus, and to provide improved means for guiding, regulating, and supporting the picture film or band in the course of its progress behind the objective or projective lens; to so construct and arrange the mechanism and the picture film or band in the inclosure or casing that a screen for the pictures may be placed before the lens and entirely free and unobstructed by the sirous of viewing the pictures can do so by simply dropping the required piece of metal money in the coin-slot to close an electriccurved film guide and support.

motor circuit and then making visual observation through the observation-openings.

The invention is fully and clearly illustrated in the accompanying drawings, where- Figure l is an end view or front view showing the operative mechanism and train of gearing, the door or closure to the casing being swung open and the lens-carrier in position. Fig. 2 isaside View in elevation, partly in section, the side of the casing being removed, the electrical circuits being shown in preferred arrangement, the picture filmor band shown as in the looped or folded condition assumed in the film box or receptacle, and the loop-line of the film from and to the receptacle indicated. Fig. 3 is a detail plan view of the coin-controlled circuit closer and breaker. Fig. 4 is a detail side elevation of the coin-controlled circuit closer and breaker. Fig. 5 is a detail plan of the condensing objective-lenses and cross-section of the supporting, tensioning, and guiding devices for the picture-film. Fig. 6 is a vertical central section of Fig. 5 and end View of .the lower film-carrying drum and edge view of the Fig. 7 is a detail plan view of the lower film-carrying drum and cross-section of the curved film guide and support. Fig. 8 is a detail of the mechanism for imparting intermittent rotation to the lower film-drum. Fig. 9 is a detail fragmentary diagrammatic view illustrating the interposition of a mirror or reflector to reflect the pictures onto the screen. Fig. 10 is a perspective view of the film-feeding devices and their operating mechanism, certain parts shown in connection therewith in other figuresbeing omitted for the purpose of more clearly showing the construction and arrangement of said devices and mechanism.

A designates a suitable box or casing, rectangular, oblong, or square, as desired, and of such size and dimensions as may adapt it to the purposes intended of affording room for the mechanism to be mounted therein and for the proper disposition of the film-receptacle. The endor front of the casingis closed by a door 1, having a lamp-box 2 mounted on its outside, and in the door is a suitable opening 3, about which is a broad box-flange 4, extending inward and adapted to receive and surround the front end of the condens ingelens when the door is closed, so that the rays of the lamp are thrown directly on and through this lens to the objective-lens. The lamp L is suitably mounted and secured in the lamp-box and is so disposed therein that itsrays shall be mainly directed through the opening in the door and be projected through the projecting-lens.

In the casing A is mounted and arranged a picture-film receptacle B of such capacity as may be desired or required to take in and hold the supply portion of the picture-film, substantially as indicated in the drawings in Fig. 2. The upper plate or top 5 of this filmreceptacle is somewhat shorter than the length of the receptacle, and the front end piece 6 is lower than the height of the receptacle, as shown in the drawings, and the space or opening th us formed is closed by two guideplates 7 and 8, the lower guide-plate 7 being directed upward and curved inward and the upper guide-plate 8 being projected forward and downward at an incline slightly curved and overlying the guide-plate 7, with a sufficient spaceor opening between the two plates to admit unimpeded the progressive movement of the picture film or band F as the film is discharged or delivered from thelower film roller or drum into the film-receptacle, At the rear lower corner of the film-receptacle is journaled a roller 9, having-the lower point, of its perimeter closely adjacent to the floor of the receptacle. This roller 9 may be located in a recess 10, formed in the end of the receptacle, and a slot 11 is formed under the end of the receptacle, between the lower edge thereof and the face of the floor or bottom of the receptacle, through which the film or band is drawn. In the casing in vertical alinement with the roller 9 is journaled a roller 12, and at the forward end of the casing is journaled another roller 13, and adjacent thereto is journaled guide-roller 14, from which the film is directed to the upper film operating and carrying drum, as will be hereinafter fully specified. Underthe upper line of the film or hand between the rollers 12 and 13 is secured a shield 16 of any proper opaque material, extending over the superficial area of the film or band at this place in order that the film or band will be completely bid at this portion.

On the film-receptacle is mounted a screen S, (shown in Fig. 2 as in direct line with the rays emanating from the projectiug-lens,) on which screen the pictures on the film are projected and to which visual observation is bad through observation-openings r 1', located at a proper place in the wall of the casing, as indicated in Fig. l of the drawings.- The screen S is preferably made concave for the purpose of correcting the spherical aberra- LlOIJS which may otherwise be produced by the lens. In Fig. 9 of the drawings -is shown a mirror m, mounted in the path of the projected rays and so arranged as to reflect the rays and throw them on to the screen arranged in another part of the casing, or at any desired position outside thereof.

In the casing A is suitably secured a base v C,- on which aremounted and secured the upbelt 21, as indicated in Figs. 1 and 2 of the drawings. shaft 22, which carries a fly-wheel 23 to maintain and equalize the movements of the mechanism. On the shaft 22 is fixed a small pinion 24, meshing with a larger gear-wheel 25 on a shaft 26. On the shaft 26 is a small gear-wheel or pinion 27 in mesh with a larger gear-wheel 28 on a shaft 29, and on this shaft 29 is a worm 30, engaging with a pinion 31 on a shaft 32, which carries on its other end the circuit-disk 61, which makes and breaks the circuits operating the mechanism, as will be hereinafter more fully specified. In the frame which supports the film-feeding devices and operating mechanism at a proper location in its upper portion is a shaft 33, on which is mounted the upper feed roller or drum 34, which draws the picturefilm from the receptacle over the rollers inthe casing and delivers it subject to the action of the lower drum. The drum 34 is provided at each end with an annular series of pins 35, which are designed to engage in perforations36, made in the edges of the picture film or band, so that the film will be drawn regularly and kept in alinement with the required direction of movement. Motion is imparted to this upper'drum 34 by means of a pinion 37 on itsshaft, which pinion is in mesh with the gear-wheel 25. A guide and directing piece or plate 38, curved in contour and reaching under the drum 34 and arranged closely adjacent thereto, keeps the film engaged with the drum and directs it upward,

as at 39, the flexible character of the film permitting the movement, and then the film is carried down in a substantially vertical direction through the film guiding and tensioning mechanism. On a shaft 40, Figs. 1, 6, and 10, is mounted the lower film drnm or roller 41, identical in construction with the drum 34, and is so placed that the film discharged therefrom is naturally directed through the The pulley 20 is mounted on a opening between the guide-plates 7 and 8 at the entrance to the film-receptacle. The shaft 40 is journaled in bearings 42, having the shaft-bearing eccentric to their axis, so that by turning the hearings in their seats the shaft 40 may be adjusted to bring the interquired to effect the displacement of one pic-' the required interval exceeding the time reture and the substitution of another therefor, a wheel or disk 42 is secured to the shaft 40 at the desired point and formed with radial slots 8, opening at the periphery of the disk, as shown more clearly in Fig. 8, to intermittently engage with a pin or lug 43, projected laterally from a disk wheel 44 on the driving shaft 22, said disk wheel being provided with an open-face ring or flange 45, against which the coincident recesses in the edge face of the slotted disk 42 rest when that element is inactive.

g designates the projecting-lens, provided with an adjustable lens-section 46, wherein a lens or lenses (not shown) are mounted as usual, and which lens-section may be adjusted to the desired focus by moving it in a wellknown manner. To the shell or barrel of the projecting-lens is secured a laterally-extending piece 44 by which the barrel is support-. ed in position,- being so held by means of a clamping-screw .47 let through a standard or other suitable support, as 48, secured in the casing and projecting into and engaging in a threaded aperture in the piece 44, as shown in Fig. 5 of the drawings. To the front of that part of the frame through which the barrel of the projecting-lens extends is secured a metal plate 49, provided with a central opening 50, through which the rays of light find access to the instrument. The opening being fixed in position, it may occur that the pictures will not aline accurately for reproduction on the screen through the instrument in such fixed relation and fragments or parts of adjacent pictures in the series he thus observed. To remedy this, a slide 51 is provided having a central opening and held to this plate at one side by a keeperflange 52 and adjusted by an adjusting-screw 53, let through a lug 53 on the fixed plate 49 and taking in a' threaded lug or sleeve 54 on the slide 51, so that the slide 51 may be moved up or down, and thus brought so that the opening will accurately aline with the vertical dimensions of the pictures to be exhibited. At the sides of the plate 49 at the top are formed or secured guide-flanges 55 to direct the passage of the film into the guiding device and to prevent lateral'displacement. To the plate 49 is hinged a,presser or tension plate 56, adapted to lie over the fixed plate 49 and is held in closed position by means of a suitable latch 57. The position of this hinged guide-plate 56 in its relation to the moving picture-film is regulated by means of an adjusting-screw 58, let through it adjacent to its front free edge and bearing with its end against the face of the fixed plate 49, as shown in Fig. 5 of the drawings. Integral with the hinged guide-plate 56 is a lenscarrier 0, in which a lens 59 is detachably secured by means of a threaded ring 60 taking in interior threadsin the lens-carrier c. The picture-film F is carried between the fixed plate 49 and the hinged plate 56 and held at the desired position by the adjustment of the screw 58, and the space or opening between the plates thus regulated, so that the pictures pass through the opening or spacebetween the adjacent ends of the lens-carrier O and the barrel or shell of the projecting-lens g. It will be seen from the foregoing description that the projecting instrument is made in two parts or sections, one of which is stationary and the other carried by a hinged plate, and that the picture-film is moved through the space provided for it between the segregated adjacent ends of the projecting instrument.

On the shaft 32 of the pinion 31 is mounted a metal disk 61, in which is fitted a suitable piece of non-conducting material 62, upon which the arm. 67 normally rests and constituting the means for making and breaking the electric circuit, and in the disk 61 is a metal pin 63, against which the coin lodges .when deposited through the coin-slot in the casing leading thereto. The supporting post or standard 64, Figs. 1, 3, and 4, is of some suitable non-conducting material, as of seasoned and dry wood, and has secured to it a contact-piece 65, connected to the circuitwire, the free end of the contact-piece lying against the disk, as indicated, and about the disk is a coin-supporting frame 66, lying adjacent to the outer face thereof and provided with a tongue or arm 67, above mentioned, the free end of which bears on the perimeter of the disk 61 and at the other end having connection to the circuit-wire, as indicated in Figs. 3 and 4 of the drawings. It will be readily perceived that this arrangement of the parts provides a mechanism in which the circuit stands normally open or broken, but that when a metallic coin is deposited and reaches the coin-frame it lodges in contact with the lug on the disk 61 and the plate of the coin frame or receptacle 66 and bridges or closes the circuit, making the electrical energy active and starting the motor, which through its connection to the operating mechanism. imparts the requisite motion thereto. It will also be perceived that when the circuit is completed and the mechanism started up the disk will be rotated by connection of the pinion 31 on the shaft with the worm engaging it, which rotation will be continued until the non-conductor portion 62 is brought into contact with the end of the tongue 67, when 'the circuit will be broken and the mechanism cle.
