In the accompanying drawing, forming a part of this present specification I have provided a diagrammatic showing of my invention, together with sectional showing of the mechanism to actuate he e ec r cal ci cu t Referring to the drawings, the preferred embodiment of my doorbell ligh't comprises an .opt side push button H), a "bell, l2 and a porch light 14 with the connecting mechanism described below.

The outside push button H1 is adjustably connected to a plunger [6 which is arranged to act against the force of a spring l8 mounted in a suitable housing 20. The outer end of the housing is closed by a plug 22 which is mounted flush with the outer end of the housing 29.

Thus the distance between the outer face of plug 22 and the under surface of push button :0 may be varied by the distance push button it is screwed into plunger iii to fit the varying thickness of house walls or plaster coatings.

The other end of plunger I6 is attached to a striker 24. When the outside push button H3 is depressed against the force of spring Is, it causes striker 24 to contact a movable contact member 26 and force it into contact with a stationary contact member 28. Contact of these

members

26 and 28 with each other closes the electrical. circuit which causes the bell l2 to operate. When the operator withdraws his pressure from the outside push button I0, the spring I8 pulls back the plunger l6 and with it the striker 2 thus permitting the movable contact member 28 to 2 sp i ook ou o .eoh ao ith the stat nary ntact m mbe 8 Th s stop th bel from ringing.

When the t de p sh att n and its ato ed pl n 1 an strike 2. a e depre sed it also causes striker 24 to strike control lever 30 which s a ached to rotata e sha t Spring means 4 s ure t at, wh n t ike v2. strikes control lever 30 and moves it a slight distance rota a le sha t .32 is rotated umoi th' o us m nua swi ch ooo oo 3 hich is integrally t ched to rotatab sh t 32 t mo out of contact with manual switch 3'! and to cause automatic switch contact 38 to move into contact with automatic switch 39.

In the position shown in the drawings, manual switch contact 36 is in contact with manual switch 31 thereby osin the o o i be ween w r and 42. In this Position it is possible to actuate switches 44 and 45 from the open position shown to a position where they establish a contact between wires Y 0 and Y42 hereby turn n on l h b the nua operati n .of' w t he 44 a d .45 wh c ere y es a is es co a be w en

wire

48 and 50 through light L4.

n t e othe hand re .5? an m be connected by the closing of switch contact 33 again t au oma ic s i c 39 when o tsid push button n s r s e as poin ed o t herei above.

Mon el s i h 44 a d ma e rota ed so that they contact

points

56 and 58 to establish contact and circuit connection between wires 40 and 42 when manual switch contact 36 is in can tact with manual switch 31. Also

manual switches

44 and 46 may be rotated out of contact with

points

56 and 58 and into contact with points 5!! and 62 to establish a circuit between

wires

52 and 54 when automatic switch contact 38 is closed against automatic switch 39. In performing these movements

manual switches

44 and 46 rotate on their pivots B4 and 66.

After light M has been turned on by depressing outside push button [0 in the manner described hereinabove, if it is desired to return the mecha nism to the condition in which it was before outside push button It! was depressed, the occupant of the house can depress inside push button 68 which is connected to plunger 10 that is mounted against the action of spring 12 in housing 14. A suitable plug 18 closes the opening of housing 14 and fits flush against the inner wall of the house. A striker 18 is integrally mounted at the other end of plunger 10.

Thus when inside push button 68 is depressed against the action of spring 12, it causes striker 18 to strike control lever 30 and rotate it and rotatable shaft 32 to its former position. This will cause automatic switch contact 38 to move out of contact with automatic switch 39 and will cause manual switch 36 to move into contact with manual switch 31 in the position shown in the drawings accompanying this application.

Thus it will be seen that depressing outside push button will cause bell I2 to ring and light l4 to be lit when

manual switches

44 and 46 are closed into contact with points 60 and 62. When this is done light [4 will remain on until the automatic mechanism is reset by depressing inside push button 68, or the system is changed from automatic to manual by moving

manual switches

44 and 46 out of contact with points 60 and 62 and into contact with

points

56 and 58. In the latter case of course, push button 68 must be depressed to cause manual switch contact 35 to come into contact with manual switch 31 and place the system on a manual operation basis.

or course, other uses for my mechanism will be apparent and my invention is not limited to the particular use shown and described in this application.

It is to be understood that the form of my invention herein shown and described is my preferred embodiment and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention, or from the scope of the appended claims.

I claim: 7

1. An electric light and bell system comprising a shaft rotatable from a first position to a second position, an arm secured 'to said shaft, a first push button and a first striker positioned to engage said arm and rotate said shaft from said first position to said second position when said first push button is pressed, a second push button and a second striker positioned to engage said arm and rotatesaid shaft from said second position to said first position when said second push button is pressed, a bell, a bell circuit, a normally open switch insaid bell circuit positioned to be actuated by said first striker to close said bell circuit while said first push button is depressed, a lamp, a lamp circuit and a switch contact secured to said shaft and positioned to close said lamp circuit when said shaft is in said second position.

2. A system as described in claim 1 in which is included means for independently closing said lamp circuit while said shaft is in first position.

3. An electric switch system comprising a shaft rotatable from a first position to a second position, an arm secured to said shaft, a first push button and a first striker positioned to engage said arm and rotate said shaft from said first position to said second position when said first push button is pressed, a second push button and a second striker positioned to engage said arm and rotate said shaft from said second position to said first position when said second push button is pressed, a normally open switch positioned to be actuated by said first striker to close said switch while said first push button is depressed, a switch contact secured to said shaft, and a pair of contacts positioned to be bridged by said switch contact when said shaft is in said second position.
