10 Claims. (Cl. 74-40) Figure '9 is a sectional view taken along line 3-'9' 'ofFigure B'showing the-stop 'pin" for the tongue and lever with thetongue not quite resting on'the-pin.

Figurelo is'a view s'imilar'to Figure 9 showing' a modified adaption of .the unique-mechanism'toan electrical circuit. Referring to Figure 1, wherein is shown the design of a binnacle for use as a cigarette, match or tooth pick holder. This figure represents one of many forms the housing, encompassing the mechanism of this invention, mayassume. Referring to Figures2,'3,' 6,- '7and'8 the mechanism consists of a-U-shaped frame provided witha base I2, ashort arm I3 and'a long arm I4. Pivotallvmountedupon :a shaft '16 housed in'arms I 3 and'I4 of .frameIl is 'a bail "provided with a tongue I8 midway-of its end pieces and a pin I9 fixed in thearm of the bail I1- nearest the long arm- [4 ofthe -U-shaped1 frame II 'andextending through is. slot 2| in said arm I4.

-A U-shaped-bracket 22 having'a base=23zand side arms '24 and 25 is fixed to base I2 of U-shaped frame II by means of a pin-26 (see Figure 9) whichrivets U-shapedbracket 22 and U-shaped frame II together. -Alever-'2'I'is pivotally mounted in arms 24 'and 25 of U-shaped bracket 22 bynieans-of ears 28 and 29-which form an integral part of :said lever-21.

-A shaft 30 is secured to base I2 by means of a threaded endtl on said shaft 3fl and a nut- 32.

' A slidable disk '.33 provided with :a sleeve -34 is freely mounted on shaft 30. The combined weight of disk 33 and sleeve -34-cause the undersideof the disk-33 to rest on lever 21. Shaft 30 is provided with a threaded portion 36 on its upper end. A bushing V3'! is threaded to portion 36. The upper surface of a bushing .38,- which .holds disk 33 and sleeve 34 together cooperates with the underside of bushing 3! to preventdisk 33 and sleeve 34'from being drawn off shaft 30 after nut 32 is screwed in position.

Long arm I 4 of U-shaped frame II has a stud 40 riveted to its upper end (see Figure 4). A pin -4I used as an anchoring means for -a spring 42 is riveted to long arm M at about-midway of I its length. Shaft I6 extends beyondth'e' outside surface "of long arm I4 as shown'in Figures z and 6 for a reason presently described.

Rotatably mounted :on-stud 40 (see Figures 14 and 5) is a disk 45 provided with aneccentric surface 46 on oneface and a split hub =41. onits opposite face (Figures 2 and 3). -A wheel '50, which may take any fanciful shapeand which is shown as a ships steering wheel in Figure l and a plain disk in Figures 2, 3 and 4, is provided with a split hub area 52 on its opposite face. Said split hub 52 co-acting with split hub 41 forms a clutch 48 when spring 53 is held in recess hub area 5| by means of a nut 54 threaded to the end of stud 40.

A dog leg shaped lever 55 is provided with a concentric cam following area 55 (Figure 5) which co-operates with eccentric surface 45 to form a reciprocating link. The lower end of lever 55 is provided with a cam following surface 51, a pin carrying area 58 and an auxiliary cam area 59. Spring 42 is secured to lever 55 by means of a rivet 6!.

Referring to Figure 6, a container 80 is secured to U-shaped bracket base 12 by means of spot Welding. The conventional shaft 35 is done away with in this figure. Disk 33 is free to be raised by lever 21. As not stay in a horizontal plane. However, when two or more disks or guide means are provided in container 80, the disk 33 will remain substantially horizontal in its up and down movement.

Referring to Figure 8, a container 80 is secured to U-shaped bracket base l2 in any conventional way as by spot welding. The relief aperture 8| in container base 80 allows for access to screw 32 fastened to shaft 30 at 3|. The mechanism and container as shown in this figure may be placed in another container having a fanciful outward design, such as shown in Figure 1.

. .Figure 10 illustrates a microswitch secured to post by means of a conventional bracket 16. An electric light bulb 11 set in a conventional socket vl8 is mounted on top of post 30. Current is supplied from any convenient source to terminals A and B. Tongue l8 functioning as before strikes microswitch button 19. Button 19 closes the electrical circuit when pressed alternately with opening the electrical circuit on the action of tongue I8.

The mechanism operates as follows: When wheel is revolved in either direction (left or right facing front of wheel) clutch 48 causes eccentric 46 to lift dog leg shaped lever (when the mechanism is in position shown in Figure 3) pin I9 resting in pin carrying area 58 is lifted; hence ball I! is actuated or caused to pivot around shaft l6. Tongue l8 raises lever 21 which in turn lifts disk 33. Spring 42 resiliently holds pin carrying area 58 against pin 19. The surface of pin l6 extending beyond leg l4 acts as a guide against cam surface 51 pushing lever 55 outwardly againstthe tension of spring 42. After wheel 50 makes one complete cycle, tongue I8 comes to rest on pin 26. Should eccentric 46 be positioned as to allow lever 55 to move down a distance beyond that at which tongue l8 comes to rest on pin 25, no damage is done because pin IE! will force leg 55 outwardly against the tension of spring 42 by means of auxiliary cam area 59.

Referring particularly to Figure 8, it will be seen that no object can be crushed by this mechanism-because anything caught between the movable cover 10 and the fixed sides H, such as a cigarette 12 here illustrated, has to merely with stand the weight of disk 33, sleeve 34 and cover Ill.

One of the outstanding results of the design of this unique mechanism is illustrated in Figure 7. Should cover Ill, hence sleeve 34 be forced downwardly when the mechanism is in its upper operating position, pin l9 will merely ride over cam following surface 51 forcing dog leg shaped illustrated, disk 33 will 4 lever 55 outwardly against the tension of spring 42. The turning of wheel 50 will cause the high point of eccentric 46 to force cam surface 51 hence leg 55 downwardly. Cam following surface 51 will ride under pin (9 until said pin falls into pin carrying area 58. Spring 42 supplies the pressure for this result to take place.

Pressure applied to cover 10 is transmitted through sleeve 34 and disk 33 to -lever 21 which forces tongue I8 downwardly and through bail H, pin l9. Cover I0 is secured to sleeve 34 by any convenient means; as by a screw 69 shown in Figure 8.

It'will thus be seen that a simple inexpensive mechanism is foolproof to turning the main control wheel 50 in either direction; to prevent crushing articles or fingers between movingparts and to forcing the mechanism against itself.
