RANGE TIMER POSITION INDICATING DEVICE Filed May 25, 1960 5 Sheets-Sheet 3 u na-Ii #9 Attorney.

United States Patent RANGE THVIER This invention relates to position indicating devices for time switches of the electric range timer type and is particularly applicable to the type of range timer having a means for automatically controlling the oven of an electric range.

Modern electric range timers often include means for setting the start time, i.e., the time at which the oven is to be turned on, and means for setting the stop time, i.e., the time at which the oven is to be turned off. In using such a timer, the housewife may set her oven for automatic operation by adjusting' her range timer to the desired settings. The timing mechanism then energizes the oven when the start time is reached, and deenergizes the oven when the stop time is reached. To provide a simplified means for setting such range timers for automatic, or time controlled operation, in certain types of widely used range timers, reciprocating and rotatable control members have been used to actuate a time controlled switch through an operating mechanism. These members, which may be referred to as starting and to their operating positions, and rotatable in their depressed positions to set the time at which the switch will be closed and opened. After the control members have been set to one of their operating positions, they then slide axially outward in response to a motor driven means to perform their actuating functions.

On occasion, the housewife may desire to manually control the operation of her oven rather than controlling it automatically. For manual operation, it is necessary that the timer controlled switch be in a closed position. With the switch set for manual, the housewife may then control the oven by means of the oven thermostat. In the aforementioned widely used range timers, the timer controlled switch may be set to its manual position by the depression of the stop control member when the start member is in its normal or unset position. The contacts of the timer controlled switch are then maintained in a closed position by latching the stop control member in its depressed position. This allows the housewife to control the oven by the oven thermostat.

In such range timers, where the timer controlled switch is selectively setfrom an off position to a timeicontrolled operation, or to a manual closed position, it has been found desirable to provide an emcient and inexpensive means for indicating the positions to which the switch J has been set by the control members.

Accordingly, it is the primary object of this invention to provide an improved range timer which has a means for selectively indicating the condition to which the switch has been set.

Another object of my invention is to provide an im-' proved range timer having an efiicient and inexpensive means for selectively indicating the positions of axially movable control members.

'A further object of my invention is to provide an improved range timer having a simplified, reliable, and durable means for selectively indicating the condition to which the switch has been set by axially movable and rotatable control members.

In carrying out my invention, in one form thereof, I have provided a range timer with an oven controlling switch which may be selectively set for timed controlled operation or to a manna closed position. Starting and ice stopping control members each have a set and a normal position and are axially slidable between these positions to actuate the switch through an operating mechanism, These members are rotatable in their depressed positions to set the start and stop times for the switch. Motor driven gears are provided for releasing the control members from their set positions to provide timed controlled operation of the switch. The stop member may be depressed when the start member is in its outer position to set theswitch to a manual or contacts closed condition where it is unaffected by the motor driven gears. In this range timer, to efliciently indicate the condition which has been set by the control members, I have provided a pivoted lever having three indicating positions. This pivoted lever is efficiently operated by the axial movement of the start and stop control members to selectively indicate any one of three conditions to which the switch has been set by the control members.

Further aspects of my invention will become apparent hereinafter, and the specification concludes with claims particularly pointing out and distinctly claiming the subject matter which I regard as my invention. The invention, however, as to organization and method of operation, together with further objects and advantages thereof, may best be understood by reference to the following description when taken in conjunction with the accompanying drawings, in which:

' Referring to FIGS. 1 and 2, my invention is shown in one form embodied in a range timer 1. The range timer 1 includes a face plate 3, clock mechanism 5, electric motor 7 for driving the clock mechanism, and oven controlling switch 9. For setting and. controlling switch 9, starting and stopping control members 11 and 13, respectively, have been provided. These members function as switch actuating and setting members for controlling the response of the switch to the clock mechanism. Members 11 and 13 each include shafts 15 and 17, respectively, which extend outwardly through face plate 3 and may be manuallyadjusted to affect the desired'timed response upon switch 9. To furnish an interval timing'signal for the operator, interval timer 19 is also provided. The mechanism of timer 19 actuates a buzzer sound at the end of a time interval which is preset by the adjustment of shaft 21.

Clock time indication for the observer is obtained from clock mechanism 5 by means of central setting shaft 23 with hour and minute hands 25 and 27 mounted thereto. The hour and minute hands rotate about time indicating embossment 29 which is formed on the face plate 3 and is appropriately divided into twelve hourly designations. Start time indicating embossment 31 and stop time indicating embossment 33 are each also formed in face plate 3 (on the left side thereof as viewed in FIG. 1). The embossments 31 and 33 are each divided into twelve hourly designations, with fifteen minute intervals indicated therebetween. Starting and stopping shafts and 17 each have an indicating hand 35 attached thereto to indicate the times at which the oven is to be turned on and off, respectively, by switch 9. Time indication for the minute timer is provided by a hand 37 which is affixed to setting shaft 21. -Embossment 39 underlies hand 37 and contains appropriate indicia for referencing thereof and setting the minute timer by the rotation of shaft 21. Knobs 41 cooperate with the slotted outer ends of each of the setting shafts to facilitate the manual adjustment thereof.

For supporting all of the various mechanisms of the range timer, front and rear plates 4-3 and 45, respectively, are provided. (See FIG. 2.) Face plate 3 is attached to the outer side of front plate 43. Threaded spacers 47 are staked to front plate 43 so that rear plate 45 may be firmly secured thereto by means of screws 49. To support setting shafts 15, 17, 21, and 23 within the timer, all of these shafts are rotatably journalled in front plate 43, with their outer end portions terminating in manually operable setting knobs 4 1. The inner end portions of shafts- 15, 17, 21, and 23 all extend through apertures in rear plate 45 to provide additional bearing support.

It will be noted that clock mechanism 5 is centrally located in the range timer, with interval timing mechanism 19 on the right side, as seen in FIG. 2. Switch 9 is disposed on the left side or" the timer (as viewed in FIG. 2), along with the starting and stopping members 11 and 13. To provide snap action for switch 9 in response to timed axial movement of members 11 and 13, a suitable switch cocking or operating mechanism (not shown) has been utilized. This cocking mechanism is mounted on the outer side of rear plate 45, and is covered and protected by switch insulating base 53. One suitable switch cocking mechanism which may be used in range timer 1 is described in detail and claimed in my copending application Serial Number 828,483 filed on July 21, 1959, and assigned to the same assignee as the present invention.

To set the starting and stopping times for the oven, as previously mentioned, start and stop shafts 15 and 17, respectively, have been provided. Starting and stopping shafts 15 and 17 are rotatably journalled for axial movement within bushings 55 and 57 (as shown in FIG. 5), and the inner ends (not shown) of these shafts extend outwardly from rear plate 45 to actuate the switch cocking mechanism and thereby close or open the switch 9. (See also FIG. 3.) The shafts 15 and 17 have gear shaped discs 59 and 61, respectively, secured mounted on a portion of each shaft between front plate and rear plate 45. Gear shaped discs 59 and 61 have apertures 63 and 65 formed on the surface thereof. (See FIG. 5.) These apertures serve to provide the preset timed axial movement of starting and stopping members 11 and 13, by engagement with mating projecting noses 67 and 69 of driven gears 71 and 73. More particularly, gears 71 and 73 are journalled for coaxial rotative movement around shafts 15 and 17, by annular bushings 55 and 57. To continuously drive gears 71 and 73, gear 74 is driven by the clock mechanism and continuously meshes with gears 71 and 73 (See FIG. 2.)

Discs 59 and 61 thus are securely mounted to their respective starting and stopping shafts 15 and 17 to form the starting and stopping control members 11 and 13. When shafts 15 and 17 are axially depressed, they are biased outwardly by suitable resilient means. In the range timer illustrated, start shaft 15 is biased outwardly to its normal position by spring 15a and stop shaft 17 is biased to its normal position by the switch cocking mechanism (not shown). Since discs 59 and 61 are at tached to their respective shafts 15 and 17, when these shafts are in their depressed or set positions, the discs are axially biased toward their coaxially arranged driven gears 71 and 73, and noses 67 and 69 of the driven gears 71 and 73 thereupon ride on the adjacent surfaces of the discs 59 and 61 (as shown in FIG. 10) to restrain outward axial movement of members 11 and 13 until the preset switch actuating times have been reached. When the preset actuating time is reached, aperture 63 or 65 is in alignment with mating nose 67 or 69 of the particular driven gear, and starting member 11 or stopping member 13 then moves outwardly due to its resilient biasing means to actuate the switching cocking mechanism and thereby operate the switch contacts.

Starting and stopping members 11 and 13 are thus axially slidable between outer or normal and inner or set positions, to set and to actuate switch 9. Upon depression of either member to its set position, manual rotation thereof sets the desired time response of the switch in accordance with the angular position of the disc aperture in relation to the mating nose of its associated driven gear. When the preset time has been reached and starting or stopping member 11 or 13 moves outwardly to perform its particular switch actuating function, the cooperation between the disc aperture and the mating nose of its associated driven gear (now also a driving gear) thereafter causes the unset start or stop member to rotate with the clock mechanism. While rotating with the clock mechanism in their normal positions, members 11 and 13 are not manually rotatable because of the large amount of gear train torque restraining the manual rotation thereof. When either one or the other or both of starting and stopping members 11 and 13 are in their depressed positions, the gear teeth of discs 59 and 61 are engaged by detent spring 75. This spring, as best seen in FIG. 5, includes a pair of V-shaped projections which are spring biased to engage adjacent teeth or rotating discs 59 and 61 when these discs are in their de pressed positions. Use of the spring 75 provides control for rotation of the start and stop members in setting the starting and stopping times for automatic operation, by serving as a detent for the rotary movement of the discs.

In some instances, the operator of the range timer may decide that instead of using the timer to automatically control the switch for oven operation, it is desirable to set the timer switch 9 to a manual or closed position. This setting allows the operator to control the oven by the oven thermostat. The manual setting may be established in my timer 1 by simply depressing stop control member 13, while start control member 11 is in its normal position. (See FIG. 7.) When this condition occurs,

i.e., stop member 13 is depressed with the start member 11 in its normal position, a latching mechanism (not shown) is provided to lock member 13 in its innermost position. One suitable latching mechanism which may be used in range timer 1 is described in detail and claimed in my aforesaid copending application Serial Number 828,483. With stop member 13 in its innermost position, as shown in FIG. 7, contact pairs 76 and 78 are maintained in a closed condition by the switch cocking mechanism where they are unaffected by the timer motor 7. Upon the subsequent depression of start member 11, the aforementioned latching mechanism is acted upon by the switch cocking mechanism and releases stop member 13 to return the switch contacts to their open position. (See FIG. 3.)

It will thus be seen that, in my improved range timer 1, the oven controlling switch 9 may be set for automatic or time controlled operation by depressing startand stop shafts 15 and 17 and then rotatingtheir, respective hands 35 to the desired start and stop times for the cooking operation. If the operator decides to set the switch 9 for manual control, to control the oven by means of the oven thermostat, all he or she needs to do isto depress stop shaft 17, while starting shaft 15 is in its normal Portion.

Turning now to an important aspect of my invention, in my improved range timer 1, I have provided a simple and eflicient means for indicating the condition to which switch'9 has been set by the control members 11 and 13. This indicating means may best be seen in FIGS. 4 and 5, and it has three indicating positions which are selectively responsive to the axial positioning of control members 11 and 13. More particularly, to provide the desired indications, lever 77 is pivotally mounted on the outer surface 79 of front plate 43. Supporting section 81 of lever 77 has an aperture formed therethrough. Shoulder rivet 83 is extended through this aperture and suitably fastened on the reverse side of plate 43 to pivotally support lever 77. Lever 77 also includes depending actuating tab 85, raised indicating section 587, and outer section 89. For biasing lever 77 in a counterclockwise direction about rivet 83 (as viewed in FIG. 5), I have provided wire spring 82. Loop 84 of spring 82 is hooked around an annular surface of rivet 83 that underlies the rivet head. Spring 82 also includes biasing arm 86 which extends underneath the right side of raised indicating section 87 (as viewed in PEG. 4) and engages angular edge 88 to exert a spring biasing force upon lever 77. To support spring 82, supporting arm 90 thereof is extended underneath lanced boss 92 of front plate 43. Spring 82 thus provides a continuous biasing force upon lever 77 to urge it in a counterclockwise direction about rivet 83 (as seen in FIG. 5).

Tab 85 of lever 77 is bent over from the main surface area of the supporting section 81 so that it extends downwardly through slot 91 of front plate 43. The slot 91 is just to the right of bushing 57 of the stop shaft 17, as seen in FIG. 5, and the left or outer edge 91a of the slot 91 is near the outer periphery of driven gear 73. The purpose of lever tab 85 shall be described in detail hereinafter.

To transmit the axial position of stop member 13 to lever 77 and thus indicate the appropriate setting of member 13, I have provided the pivoted actuator 93. Actuator 93 is extended between the front plate 43 and the rear plate 45, and as shown in FIG. 5, it includes operating extension 95 and pivot extension 97 which are formed at its respective ends 96 and 98. Extension 97 is received by pivot slot 99 of rear plate 45 and serves as a pivoting support for the actuator. Extension 95 is disposed through slot 91 of front plate 43 to engage tab 85 of lever 77 as the actuator 93 pivots within slot 99. (See FIGS. 4 and 5.) For receiving the reciprocal motion of stop member 13, between the tab extensions 95 and 97 of actua tor 93, an elongated follower or tongue section 101 is lanced. Follower 101 is struck from the main surface of actuator 93, being angled outwardly therefrom toward the supporting or pivoted end 98. i

As shown in FIG. 2, follower 101 is angularly positioned underneath an overlying segment of disc 61 of stop member 13 when the stop member is in its normal or outer position. Operating extension 95 of actuator 93 then loosely engages tab 85 of lever 77 and has no effect upon the lever. As stop member 13 is depressed, disc 61 then moves inwardly and serves to cam the follower 101. This causes actuator 93 to pivot in a clockwise direction (as seen in FIG. 8). When actuator 93 pivots in response to thedepression of stop member 13, operating extension 95 of the actuator engages tab 85 of the lever and forces the lever to rotate in a clockwise direction (as viewed in FIG. 5) against the biasing force of its spring 82. Lever 77 then assumes either its set position (FIG; 9) or manual position (FIG. 6). Whether the lever 77 indicates the set or manual positions is of course also dependent upon the axial positioning of start member 11, as shall be described in detail hereinafter.

To transmit the axial positioning of start member 11 to indicating lever 77 where necessary, and thus enable my position indicating device to selectively respond to the operative positions established by axial movement of both the start member 11 and the stop member 13, I have provided spring biased reciprocating stop 103. (See FIG. 5.) Stop 103 includes a supporting shank 109 and a pair of projecting fingers 105 and 107 which are spaced apart by about The outer end of shank 109 is extended through slot 111 of rear plate 45 and a portion of, the shank extending inwardly from plate 45 (i.e., toward plate 43 has a coiled compression spring 113 surrounding it.

Spring 113 runs in compression between plate 45 and shoulders 117 of stop 103 to normally bias outer tip a of finger 105 outwardly through slot of the front plate 43. (See FIG. 4.) Shoulder 105k of stop 103 limits the outward movement of tip 105a by engagement with front plate 43. Finger 107 is thumb-like in appearance, as shown in FIG. 5, and it includes a raised edge 119 which underlies and faces the side of start disc 59 toward switch 9. When start member 11 is in its normal position, edge 119 of stop 103 is spaced apart from disc 59. Stop 103 then stretches between plates 43 and 45 and is spring biased so that the outer tip 105a of finger 105 extends through slot 115 to project outwardly, as shown in FIG.

4. When the start member 11 is depressed, start disc 59 moves to its position as shown in FIG. 10, and engages finger edge 119. This forces stop 103 to move further through slot 111 of plate 45, against the biasing force of spring 113. Outer tip 105a is thus partially withdrawn from its slot 115 (as shown in FIG. 10) and it no longer protrudes from the outer surface of front plate 43. The purpose and effect of the coaction between start member 11 and stop 103 shall become apparent hereniafter.

For cooperating with outer tip a of stop 103 in response to the positioning thereof, my indicating lever 77 has a convergent indentation 121 formed upon it. More particularly, raised edge portion 89a is formed on one shown in FIG. 6, to restrain the lever from counterclockwise movement.

Turning now to a detailed explanation of the operation of my range timer indicating device, when the timer is not being used, the start and stop shafts 15 and 17 are in their normal positions, as shown in FIGS. 2 and 3. Indicating lever 77 is then biased by spring 82 to its extreme counterclockwise position (viewing the timer from the frontthereof). The OFF indicium then underlies slot 123 of face plate 3 (as shown in FIG. 1) to indicate that the range timer has not been set.

When the operator decides to set the timer 1 for manual operation (where the switch 9 is in closed position unaffected by the timer motor), as previously described,

he or she depresses stop shaft 17. When shaft 17 is depressed, stop disc 61 which is attached to it moves to the position shown in FIG. 8, and nose 69 is spaced slightly from disc 61 by engagement of the latching member (not shown) with stop member 13. During this downward movement of stop shaft 17, disc 61 cams follower 101 of actuator 93 to pivot it clockwise from the position where it is shown in FIG. 2 to the position in which it is shown in FIG. 8. This pivotal movement of actuator 93 causes operating extension 95 to engage tab 85 of the lever, and moves lever 77 in a clockwise direction to the position shown in FIG. 6, against the counterclockwise biasing force of spring 82 (viewing the timer from the front thereof). When outer section 89 of lever 77 moves in a clockwise direction, the convergent indentation 121 permits it to ride over the outer tip 105a of stop I03. After fiat edge 89b of the lever has passed outer tip 105a, it is engaged by tip 105a to maintain lever 77 in the indicating position shown in FIG. 6. The MAN (manual condition) indicium then underlies slot 123 of face plate 3 to indicate that the contact pairs 76 and 78 of switch 9 have been set to a closed position, where they are unaffected by the timer motor.

When the operator decides to set range timer 1 for automatic or time controlled operation of the oven controlling switch 9, he or she depresses both the start and stop members 11 and 113, and then rotates them so that the indicating hands 35 point to the desired start and stop times for the oven cooking operation. When the start and stop members 11 and 13 are both depressed, they are in the position shown in FIGS. 10 and 11. Driven gear 71 of start member 11 is then separated from start disc by nose 67 of gear 71, and driven gear 73 of stop member 13 is separated from stop disc 61 by nose 69 of gear 73. Stop gear 61 is thus slightly closer to gear 73 than when the stop member 11 is set for the manual condition (as will be understood by a comparison between the positions in FIG. 11 of disc 61 in full and disc 61a in dotted representation). Gear 61 engages follower 101 to urge actuator 93 to the position shown in'FIGS. 9 and 11. Operating extension 95 of actuator 93 thus engages tab 85 of lever 77 to urge the lever into the position shown in FIG. 9, against the biasing force of spring 82. Lever 77 is then disposed in its intermediate indicating position, where the SET time controlled) indicium underlies slot 123 of iace plate 3 to indicate that oven controlling switch 9 is to start and stop at the particular times established by the setting of start and stop members 11 and 13.

When range timer 1 has been previously set to its manual condition and the operator sets the times for automatic or time controlled operation, the downward movement of start member 11 oausm start disc 59 to engage edge 119 of stop 103. This forces finger tip 135a inwardly to the position where it is shown in FIG. 10. Finger tip 105a thus no longer protrudes outwardly from the face of a front plate 43 and lever 77 is free to pivot past it in either a clockwise or a counterclockwise direction.

It will now therefore be seen that my new and improved range timer provides a very simplified and efiicient means for indicating the condition to which the switch has been set in response to the axial movement of starting and stopping control members. This indicating means is also reliable and inexpensive and lends itself advantageously to many range timer applications. It should be realized that certain aspects of my invention may be incorporated efiiciently and beneficially in other various types of range timers.

While in accordance with the patent statutes, I have described what at present is considered to be the preferred embodiment of my invention, it wil be obvious to those skilled in the art that various changes and modifications may be made therein without departing from my invention, and I therefore aim in the following claims to cover all such equivalent variations as fall within the true spirit and scope of this invention.
