TIME SWITCH.

applicati@ med :une 25, 1,921. seriai No. 480,412.

This invention relates to improvements in time switches, the general object oi" the invention being to provide clock means for moving the switch toy its open position and also to provide manually operatedfrneans `for actuatingthe switch.

Another object of the invention is to provide a dial and a cooperating inger which is Vconnected with the arbor of the clock mechanism with means for connecting said arbor with the switch and with a setting disc.

A further object of the invention is to provide ai shaft which passes through the l5 hollow arbor and carries the switch blade 'and a finger disc.

A still further object of the inventionis to provide a casingr i'or the clock mechanism with insulated blocks at the rear thereof' 2for containino the switch parts and into which the arbor and' switch shaft extend.

This invention alsofconsists in certain Vother' features of construction and in the combinationand arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing my inventionin detail` ret- 3. erence will be had tothe accompanying drawings wherein like characters denote like or correspondingparts throughout the several views, and in which Figure 1 is a front view of the invention. .'15 Figure 2 is a longitudinal sectional fview.

Figure?) is a View of the rear face of the inner block showing the parts of the snap switch. i

Figure 4` is a view ot the oppositev face le of this block showing the time switch.

Figure 5 is a view similar to Figure 3 with the switchl blade arranged in inoperative position.

Figure 6 illustrates perspective views of some of the parts of the switch.

In these views 1 indicates the casing for enclosing the clock m^chanism which is indicated generally at-2. The hollow shaft or arbor 3.'to which the spring 2 of the clock mechanism is connected, extends entirely through the casing with its ends projecting therefrom. The indicator finger 4 is suitably connected with the front projecting end of said arbor. This end of the a5 arbor is provided with the notches which are adapted to receive the projections 6 of the setting disc 7 so that the spring can be wound and the finger adjusted to its desired position on the dial 8 on the front face of the casing. The rear projecting end of the sha-tt or arbor has secured thereto the ring 9 which is provided with the projec tions 10 for engaging notches 11 in the switch member 12 so that said member will be caused to move with the arbor. This switch member is rotatably mounted on a hollow stub shaft 13 which is mounted in the insulation block 14 secured to the rear of the casing. This block is provided with recesses in its inner and outer faces to receive the switch parts. A split metal ring 15 forms the walls of the inner recess the split ends beingconsiderably separated, as sho-wn as 15 in Figure 6 and a projection 16 formed on the block projects into this space and acts as a stop for the switch member 12. This member 12 carries a spring plunger 17, the spring of which holds the outer end thereof `against the ,ring 15 to keep the same in electrical contact with said ring 15 but this electrical connection if: broken when the switch member reaches a position Awhere the plunger will. ride ol the metal ring into the space -15 between its ends. when this plunger strikes the stop 16 further movement of the switch member and its attached lparts will be prevented. This extends through the block into the recess `in its rear` face and engages the contact 19 which'is adapted to be connected with one terminal ot the electric circuit. A ratchet ring 2O is located `in the rear recess ot blo-ck 14 and is connected with the stub shaft 13 bvhavingv an inwardly extending` projection '.,i

21 engaging the shaft and held thereto bv the lnut 22. This ring 2() is connect-ed with the second contact 23 to which the second terminal of the electric circuit is adapted to be secured.

It will thus be seen that when the plunger 17 is in contact with ring15 the circuit will be completed between the two contacts 19 and 23 through ring 15 and its ear 18, the switch ring 15 is provided with an ear 18 which Thus by rotatv iii) longer the circuit will remain en. The extent of this movement of the parts is indcated by the finger moving over the dial so that a person can adjust the, arts t ,keep the current iowing for anum er of hours or fractions thereof, This settin ment will also wind the spring of t e clock mechanism and as soon as the seidmovement ceases the spring acts to return the parts to place the finger at zero and to move the plunger oif vthe ring.

I also provide means for manually making and breaking the circuit, such means consisting of a. solid shaft 24 which ,passes thlrouglfi the arbor and :the stub shaft 1-3 and disc 7 and vhas its front end screw threaded to engage the screw threaded fbore of the finger disc `25. The rear end of said .shaft carries a menrber Q6 which is provided with a square part which passes through a square opening 'for-med yin aY switch blade 27 which engages the ratchet teeth in ring and Iis also adapted `to engage the :projecting part of Contact 19. A spring -28 on the -member 26 permits the switch blade to slide over the ratchet teeth. As will 'be seen when rthe blade is in engagement with the contact 19-the circuit between `the contacts 19 an( 23 will be completed as ratchet ring 20 is electrically connected with eontact 23. Thus by manipulating disc 'the circuit can 'be closed Vwhilewthe time switch Vis in oilI position.

The switch parts `on the outer 'face' of block 14 are covered by a second insulation block 14 which is secured to the first b'lock and is provided with a central recess for lreceiving the member 26. The dise 2.5 acts to hold the disc 7 in position.

From the above it will` be apparent that the time switch can be set so that it will 'break the circuit at some future time and the snap switch can be used for making and breaking the circuit when the time switch is in inoperative position.

It is thought from the foregoing description that the advantagesand novel fedtures of m invention will be readily apparent.

I diesire it tov be understood thaft I may make changes in the construction and in the combination and arrangement of the several parts, provided that such chan es fall within the scope of the appended 'c aims.

What Icleim isz- `1. A switch comprising a casing, an insulating block secured to the rear of said casing and being formed with inner and outer: recesses, Va hollow shaft passing through said casing and having one end arranged in the inner recess, a stub shaft arranged in the ,black and extending into said recesses, means of hollowr'shaft land stub shaft respectively, a ratchet ring arranged in the outer recess, a projection vextending inwardly :from Vthe ratchet ring and securing the latter to 'the stub shaft, a solid shaft passingthrough the hollow shaft and stub shat, a `member having afsquare art secua'ed to the solid shaft, a switch 'b'la e secured to the square pa-rt and resiliently retained ened in the iteeth of the ratchet ring, and a contact member arranged in the Vpath of the switch blade which is movable upon rotation of the solid shaft.

2. A time switch comprising a casing, a dial on the front of said fcaaing, 'an insulating block secured to the rear .of smid casing and being formed with a reoess,'a yhollow shaft passing through said `casing and extend'img into fthe recess, 'means in the casing for rotating said hollow shaft, an indicating finger on said hollow shaft and cooperating with lsaid ldial, a stub shaft iin the insulatin block, a switch member secured to 'the st shaft and disposed in the recess, a ring secured to the hollow shaft and having pro-f jections received in notches formed 1n the switch member wherebyv rthe latter is rotated by the movement of the hollowsha'ft, a split ring engaged iin the recess vand Ahavconnection between the' ing its .ends s aced, 1a laterally disposed@ plunger secure 'to the switch member and heilig normmlly engaged with the split ring, a projection formed on .the block amd arvrangedin the space between the ends of the split ning and also in the path iof the switch member to limit the rotation of the plunger Vwhen it leaves the split ring, and a setting disk on the hollow shaft for arranging the indicating nger and switch member simultaneously aft predeterxrrined lpoints for the -purpose speci ed.

In testimony whereof i aix my signature.
