To LZ/f whom it may carl/cern:

Be it known that I, JULIUs C. LIEBHARDT, a citizen oi' the United States, residing at Belleville, in the county oi' Essex and State of New Jersey, have invented new and usoful Improvements in Clutch Mechanism for Exhibiting-Machines, oi which the following is a specification.

This invention relates to a clutch mechan-A ism which has been applied to practical use in connection with a motor for an exhibitingmachine, but which is not restricted to said use.

This invention is set forth in the following specification and claims, and illustrated in the annexed drawings, in which- Figure 1 shows a iront elevation of mechanism embodying this invention. Fig. 2 is a sectional view of parts of Fig. 1, the section being taken along :t 9c, Fig. 4. Fig. 3 is a section along y y, Fig. 2, showing coupling or uniting means between the crank and a clutch member. Fig. 4 is a side elevation oi Fig. 1. Fig. 5 shows an incline or cam for the picturelifting lever. Fig. 6 shows means for preventing accidental shift of lever. Fig. 7 shows the machine in its case or inclosure, the latter broken to allow certain exposure. Fig. 8 is a side elevation of Fig. 7. Fig. 9 shows returning means for a phonograph-reproducer. Fig. 10 is a plan view of Fig. 9, the pictures being omitted to expose underlying parts.

In the drawings is shown a coin slot or entrance 1, Fig. 7. A coin passed thereinto and forced by plunger or pushers 2, Fig. 8, along way 8, passing under lever 4, will tilt or move the latter. From the way 3 the coin can be led along a chute 18 to a receptacle or holder 19.

The lever 4 is shown iulcrumed at 5, and when actuated this lever will tilt a second lever 7, Fig. 1, about its pivot 8. This tilting lever is weighted or has a disk, as seen, and remains in the position to which it is tilted to one side or another of its pivot until returned by suitable means. A friction. or retaining spring 96, Fig. 6, sitting against a shoulder or ridge on the lever or its weight, prevents accidental shift. This lever 7 has a shoulder-and-tooth connection with a lever 9, Fig. 2, having pivot 8 in common with lever 7. This lever 9 moves a clutch member 1-1 back and forth to couple or uncouple the same with clutch member 15. Said two members have suitable toothed or engaging lfaces or portions.

When the clutch is in engaging position, the crank 23 is coupled with slia'lt 17, connected or coupled at 2() with the springmotor 21 of the phonograph 22. The .clutch member has gear connection 16 with gear 24 of the picture and light operating mechanism. This gear, as presently seen, serves several purposes. Connected to gear 24 are cams 25 26, Fig. 1. The cam 25 engages an arm 29, Fig. 4, extended from fulcrum-rod or rockshaft 81, from which extend arms 80. The pictures or sets of pictures when in their lowermost position rest on a rod or crossbrace 48. When the lever-arms are actuated, they raise the pictures to elevated or exposing position, so that they can be viewed or from which they drop as they are viewed. As the pictures are lifted they are hold raised by arms 28 until the time for drop ping has arrived. This dropping is effected by cam 26, also connected to gear 24. Cam 26 engages an end or portion of a lever-arm 36, extended from shaft or ilulcruin-rod 35, carrying the levers or arms 28 28a. Two arms 28 28d are shown, Fig. 1, one each for the respective sets or series of pictures. From the levers 28 and 28ab or rock-shaft 35 extend elongationsy or arms carrying contacts 37, which in connection with switches or terminals 41 control the lighting of the two compartments by making or breaking circuits.

Gear 24 has a projection 43, Fig. 4, which serves to disengage the winding mechanism or crank after the proper numb er of turns has been given by .handle 23. As this projection is carried about in winding and strikes onto lever 44 the latter presses on the tilting or weighted lever 7. This lever 7 thus actuated swings to disengaging position or moves lever 9 so that the latter frees the clutch member 11 or slides the same to uncoupling position. Said gear 24 also carries a stud 42, adapted to engage a nose or laterally-projecting part 47 oi lever or arm 44. When the stud 43 moves the leverarm 44 one way, it uncouples the clutch, as noted, and said lever 44 also, by link 45 and lever 46, releases the brake or stop disk 47 of the spring-motor to leave the device free to operate. As the IOO gear 24 returns or moves back the stud 42 engages the projection 47 to move the lever the other way and put on the brake or stop the mechanism by the arm or lever' 46 engaging the brake or stop.

The base 51, with support or frame pieces 49, carries the mechanism, and the connection or cross-bar 48, already mentioned, braces or stiffens the structure, in addition to acting as a support or stop for dropping pictures.

To operate the device, a coin is introduced and forced by plunger 2 past -under lever 4, which latter being thereby tilted and acting on lever 7 throws the latter over to vcause lever 9 to move clutch member 11 to engaging position with member 15. This sliding or feathering clutch member 11 is connected with the crank-lever 23 by means of aratchetpawl 60, Fig. 3. The hub part of the cranklever 23 has a feather connection with the clutch member 11, so that these parts turn together; but the clutch member 11 can' slide to and from the member 15 to couple and uncouple. The excentric slots are so arranged that they will always be engaged by pawl 60 when crank 23 is turned to the right and that the pawl will slip past the same on turning in the opposite direction. The clutch member 11 being thrown into coupling position and the crank turned to the right, the clutch member 11 being rotated will turn member 15, connected by pin 61, Fig. 2, with shaft 17. Said member 15, as noted, also turns gear 24 or meshes into the same. The shaft 17 by coupling 20, Fig. 1, winds the spring-drum 21. The gear 24 being rotated carries its stud or projection 43, Fig. 4, to lever 44 to move the latter and return or throw lever 7 back to its startingpoint or into position to move lever 9 with clutch member 11 to disengaging position or away from member 15. The crank-lever is now again idle or disconnected from the machine and can be turned either way without affecting any part of the mechanism. The rotation of gear 24, with the cam or incline 25 secured thereto, actuates leverarm 29 and rock-shaft 31, so that the free ends of its arms 30 swing up and raise the cards or pictures 27. Such free ends of arms 30 are bent laterally a sufficient distance to engage the cards or pictures to raise the same. The lever 28EL has connected thereto a shoe D2, having a rim D. The other lever 28, as shown in Fig. 9, can be left plain or without such shoe attachment. As the arms 30 rise one of them engages shoe D2 or the rim D thereof and raises the lever-arm 28a and rocks the shaft 35 so as to swing the upper or free ends of these lever-arms out of the way of the lugs C C2 C3 C* on the cards orleaves 27, so that these cards can be swung up to the required extent. /Vhen the pictures have been raised and the lever-arm 30, engaging shoe D', has passed said shoe, the lever 28a drops against the lug C of the first picture, and the pictures are held up for the commencement of the operation or Working of the machine. As the spring-motor operates the gear 24 is rotated by clutch member 15 and teeth 16 at the same time that the phonograph performs its function. The cam 26, rotating with gear 24, actuates the arm 36 with shaft 35 and levers 28 and 28a, so that the latter'oscillate to and from the non-alined lugs C to C4 and allow a picture section to drop while the others are held up. The contacts 37 being also actuated with rock shaft 35, the lights are started or extinguished, as required.

The lugs C at opposite sides, as also levers 28 and 28, could be placed in alinement, in which case the respective picture-sections drop simultaneously. if either of these lugs is placed out of alinement or the lever-arms 28 and 28a lare out of alinement with one another, the drop of one picture-section will not be simultaneouswith that of the other. /Vhat has been said with respect to placing the lugs C out of alinement with one another of course applies likewise to all succeeding lugs or picture-sections. It is also to be noted that if the arms or contacts 37 and terminals 41 at opposite sides of the machine are placed in alinement with one another the lights will be simultaneously lighted and extinguished. If, however, contacts 37 or terminals 41 are not in alinement with one another, the lights at the opposite sides are not lighted or extinguished simultaneously. The contacts 37 can be in the form of flexible blades to spring or yield as required.

The phonograph reproducer is shown at 62, Fig. 9, pivoted at 63 to the carriage 64, driven by a screw 65. At the end of a performance or exhibition the reproducer is cleared or lifted off the record and returned to the starting-point. A lifter or automatic arrangement for taking the reproducer out of contact can be provided and is constructed as follows: From the stopping device or brake 47 or its link 45 can extend a connection or wire 68 to an arm or lever 66 on the lifter or bent wire 67. As the link 47 moves its brake to stopping position the connection 68 moves lever 66 to bring the high part of the wire or lifter under the reproducer. The latter is then raised or swung about its pivot away from the record. As the motor is wound up the carriage-propelling screw is rotated in backward or return direction and draws back the reproducer, the latter sliding along the high part of the lifter. When the device is started, or, in other words, when the brake is freed, the connection 68 is released or moved to allow the high part of the lifter to drop or swing from under the reproducer. As the reproducer drops to contact with the record and the motor starts and carries the screw to move the reproducer forward the phonograph operates.
