CHARLES'E. LUCKE, NEW YORK, N. Y.
EXHIBITING DEVICE.
SPECIFICATION forming part of Letters Patent N o. 674,21 1, dated May 14, 1901.
Application led September 25, 1900. Serial No. 31.029. (No model.)
To all whom it may concern:
Bo it known that I, CHARLES E. LUcKE, a citizen of the United States, and a resident of the city of New York, Kingsbridge, borough of the Bronx, inthe county and State of New York, have invented certain new and useful Improvements in Exhibiting Devices,`
minating the sign or other article, and, sec;` yond, to construct a simple compensating de-` vice to bring each picture or advertisement into the proper position notwithstanding the variation in the diameter of the roll of band or ribbon.
To these ends my invention consists in certain features of Aconstruction and' combinations of parts, as will be fully described hereinafter, and particularly pointed out in the .appended claims.
Reference is to be had to the accompanying drawings, forming a part of this specification,
in which similar characters of reference indi-3 cate correspon-ding parts in all the figures.
Figure 1 is a side elevation of my improved exhibiting device with the casing in section. Figs. 2 and 3 are respectively a sectionalrear elevation and a horizontal cross-section on lines 2 2 and 3 3 of Fig. Vl; and Fig. 4 is a view, corresponding to Fig. l, of another form of my invention.
As illustrated by Figs. l, 2, and 3, the apparatus comprises a suitable stationary box or casing A, having a sight-opening A', which may contain a transparent pane A2. Within this casing is pivoted, as at B', to bracketsB the frame C of the exhibiting device. The pivot, as shown, is located at the rear bottom corner of the frame, and infront of the pivot springs D are interposed between the frame and the bottom of the casing A, so that'the frame has a tendency to swing upward at-its front end, the position of the frame being governed by a stop-wheel E, journaled at E on a bracket E2, fixed to the back Wall of the casing A. This stop-wheel E is engaged by a cam F3, mounted on a shaft F, journaled in the frame, and it will be understood that thel position of the frame will vary as the cam F2 turns. The mechanism controlling the cam F2 will be described hereinafter. It will be obvious that instead of interposing compression-springs between the frame C and the bottom of the casing A the same result may be secured by locating tension or suspension springs between tlie top of the casing and the frame.
Within the casing is located upon a support A3 an electric lamp-for instance, an incandescent lamp G-V-one terminal of which is connected, as by a wire G', witha source of electricity, While the other terminal of the lamp connects by a wire G2 with a contact'- plate H, secured to the frame C. This contact' plate is adapted for engagement with a switch-lever I, fulcru med at l and drawn by a spring K against a cam L on ashaft L, journaled in the frame C and driven from the main shaft F by gearing F2 L2. The` lever l is electrically connectedas by a wire I2, with the other pole of the source of electricity or with the ground, so that the circuit is completed and the lamp (SrV lighted when the switch-lever I engages the contact-plate H.
On the shaft L is fastened a mutilated gear Wheel L2, meshing with a pinion M on a shaft M, which is journaledin an arm N, fulcrumed on the shaft L-that is', loosely mounted 4on said shaft. wheel M2, movable between two wheels O P to engage one of them at a time. In the position shown in Fig. l the gear-wheel M2 engages the upper wheel O', and the shaft M is held in the proper position for this purpose` ,by the engagement of the arm N With a rib or cam F on the shaft F. When the arm N is released by the cam F', the weight of the arm, with the parts carried thereby," (wheels M M2, and shaft M,) assisted, if necessary, by a spring, (not shown,) will cause the Wheel The shaft M also carries a gear- M2 to dropinto engagementv with the lower wheel P. The wheels O' E' are mounted on shafts O P, respectively, journaled in the frame C. The upper shaft O carriesthe roo spool O2, on which is secured one end of thel l band or ribbon Q, having a series of pictures, advertisements, 6to. The lower shaft P has a bevel-wheel P2, meshing with a similar wheel R2 on a vertical shaft R, journaled in the frame C. At its lower end said shaft carries a bevel-wheel R', meshing with a bevel-pinion S on the shaft S of the lower spool S2, this shaft being journaled at the lower portion of the frame C. The spools O2 S2, or rather their shafts OS, are provided with tension devices which may consist of friction-disks O3 S3, engaged by springs T T', secured either to the casing A, as shown, or preferably to the frame C. The various parts are driven by power applied to the main shaft F in any suitable manner-for instance, by a spring-motor, the barrel of which is lettered U in the drawings.
The operation is as follows: In the position shown in Fig. l the wheel M2 is in mesh with the wheel O', so that the upper spool O2 is driven. The feed movement is almost completed as the toothed portion of the mutilated gear L3 is about to come out of contact with the pinion M'. Also the cam L is just beginning to act on the lever I to swing it into contact with the plate H. The parts are so arranged that at about the same time the contact is made the pinion M will stop, owing to the toothed portion of the gear L3 leaving said pinion, so that the lighting of the lamp Gand the stopping of the band Q will be simultaneous. Then for a while (a half-revolution of the shaft L) the picture exhibited will remain stationary, being illuminated during this time by the lamp G. Then the cam L will clear the lever I, so as to break the circuit at H, extinguishing the lamp G, and at the same time the toothed portion of the gear L3 will again come into mesh with the pinion M' to drive the spool O2, so that the paper or other baud Q will travel upward a distance corresponding to the length of the picture, advertisement, or other article. Thus there will be periods of darkness, with simultaneous motion of the band Q, alternating with periods of illumination which coincide with the stoppage of the band Q. This will continue until the band is fully Wound on the upper spool O2. At that moment the cam F releases the arm N and the driving-wheel M2 drops into engagement with the gear-wheel P. From now on the operation is the same as before described, except that the spool S2 is driven so that the band Q travels in the opposite direction-that is, downward.
It will be obvious that with lthe arrangement hereiubefore described the angular velocity or rotary speed of the spools O2 S2 is about constant. It follows that as the diameter of the band on the spool increases a greater length of the band will be fed than at the preceding operation and the picture to be exhibited would be raised too high or loweredtoo much, and therefore fail to `properly register with the opening A of the casing A. To compensate for this, I have provided the cam F3, which is of such a shape as to cause the frame C to belowered when the band Q winds on the upper roller and to be raised when the band winds on the lower roller. This is the operation approximately that is, the movement of the frame will be such as to counteract the above-mentioned effect arising from a variation of the amount of material on the rollersor spools and as to always bring each picture into perfect registry with the sight-opening A'. It will be understood that a purely vertical movement of the frame C would accomplish the result above set forth.
It will be understood that the Wheel E practically forms a part of the casingA. In fact, the cam F3 might engage the casing directly, (dispensing with the Wheel E,) the only objection to this being increased friction.
In Fig. 4 I have illustrated another apparatus for carrying out that part of myinvention which relates to lighting and extinguishing the electric light in accordance with the periods of stopping and moving the picturestrip. ct i`s the casing, having the sight a'. f is the drive-shaft, with a gear-wheel to drive the pinion Z2 on the shaft Z. The latter carries the mutilated gear Z3 and the switchoperating cam Z', which, asin the construction first described, is located correspondingly to the toothed portion of the gear Z3. The cam operates the switch-lever 1l, fulcrumed at z" and adapted to engage the contact-plate 7L. The electrical connections of the switch t', contact-plate h,and lamp gare the same as in Figui and are lettered g,g2,and 2,respectively. The mutilated gear Z3 drives intermittently1 a pinion m on a shaft m,wl1ich carries a feed-roller@ for actuating the band or strip q, which in this case is endless and passes over guide-rollers W. o is a tension-roller for holding the strip q against the feed-roller 'U. In this construction also the switch is so operated as to light the lamp g only when the strip q is statonary.
Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In an exhibiting device, the combination of a shaft adapted to rotate continuously, a mutilated gear on said shaft, a feedmechanism driven intermittently by said 'mutilated gear, an electric light, a switch for controlling the supply of current to said light, and a switch-operating cam mounted on saidshaft and arranged to open the circuit at the time the mutilated gear is in the driving position.
