This invention relates to time actuated electrical control devices adapted to start and stop the current supplied to electrical accessories such as stoves, toasters, electrically controlled furnaces and electric heaters as well as fans and other motor operated apparatus, radios and alarms, etc., as well as large electrically controlled equipment.
It is so constructed as to enable the housewife to easily set the mechanism to any predetermined time for supplying the current for any period of time by plugging in the particular device to be-controlled and the clock to the ordinary house current. a
The objects of my device are: To start and stop automatically any electrically actuated equipment at the time of setting or at a future time: To accomplish this resultwith a single circuit from the source to the device being operated: To provide a controlling device that is easily set: To proa0 vide a portable compact controlling device that uses direct or alternating ordinary current at the voltage and amperage commonly used in household circuits.
The time mechanism may be of the spring wound eight (8) day or one day construction or electrically operated clock movement as it is obvious that as the contacts that make and break the circuit are actuated by the hour or minute spindles or sleeves of the clock works that any type of clock movement may be used. The movable spring contacts or brushes move in the exact relation to the hands of the clock as they are secured to the same parts that the hands are secured to.
I do not wish to be limited to the exact construction of the several parts as the size and type of contacts used and the manner of assembling them may be accomplished in numerous ways depending on the amperage and load as well as the type and size of clock used.
I have shown and hereinafter set forth the several parts of my invention which by referring to the accompanying drawings may be followed as similar reference numerals refer to similar parts throughout the several views in which:
Figure 1 is a side elevation of my device in which the housing is broken away to show the wiring and contacts as well as the parts of the clock coacting with the electric circuits.
Figure 2 is an elevation of the face of one of the contact discs showing the relation to the revolving brush.
Figure 3 is a fragmentary view of the rear of my device showing a portion of the housing broken away to reveal the five minute contacts and wiring to the switches as well as the arrangement of the switches on the rear of the clock.
Figure 4 is a front elevation of my device showing portions of the face and parts broken away and the relation between the hands of the clock and the contacts.
Figure 5 is a wiring diagram of my device in which the pairs of discs are shown as opened up, or arranged in the manner of opening the pages of a book, so that their faces and the contact segments thereon are presented to view.
Figure 6 is a rear view of one of the switches of my device.
Similar reference characters refer to similar parts throughout the several views of the accompanying drawings.
The housing 1 of the clock is modified at the base to provide the switch board 2, on which are mounted the hour switches 3 and five minute switches 4. The number of switches and also the type used are subject to modification to suit the conditions of operation, the amperage carried in the circuits and the purpose to which my device is applied. It may be desirable for some uses to increase the number of switches and the contacts to decrease the time of contact to one minute instead of the minimum of five minutes as shown in the accompanying drawings or to decrease the number of switches and contacts so that several hours would be the minimum time of contact.
It is also obvious that if a greater amperage than the parts are suitable for, is desired that a motor or electrically operated switch may be controlled by my device.
The framework 5, of the time movement supports the discs 6, 7, 8 and 9, which are held in fixed relation thereto by the stanchions 10.
The time movement may be electrically or spring operated and the minute spindle 11, and hour sleeve 12, which move the minute hand 13, and hour hand 14, are provided with brush arms 15 and 16, carrying the resilient brushes 1'7, 18, 19 and 20.
The discs 6, '7, 8 and 9 are provided with contact segments 21, each being slightly less in segmental length at the radius travelled by the brushes than the distance travelled at the same radius by the hour hand between each hour. Thus the width of the brush is compensated for by the segmental contact being less than the 30 or one-twelfth of i the circle traversed by the hands and brushes. As the discs and their contacts are arranged face to face, at fixed relation with the brush contacting with them, the point opposite the contact segment 21, of one disc is insulated thus each 'cclock and be shut off at 4:10 oclock.
brush in its travel makes alternate contacts in relation to each of the two discs separately and continuous contacts with the segments of the pair of discs combined.
The discs 6 and '7 form one pair, the discs 8 and 9 the opposite pair.
Following the circuit it will be seen each of the contact segments 21, is connected to one of the poles of the switches 3 and 4 by wires 22 and the wire 23 connects the opposite poles. The brushes 1'7, 18, 19 and 20, the brush arms 15 and 16, the spindle 11 and sleeve 12, as well as the works and framework are connected by the wire 24, to the source of current supply or electric generator 25.
The lamp circuit, heater, motor or other appliance 26, is connected to my device by the plug 27, preferably connected to the wire 23, which is connected to the switches 3 or 4, that may be closing the circuit as will be seen by the following description of the operation of my time control.
.The light 26, or other electrical accessory is plugged in as may be seen by referring to Figure 1 of the drawings and the clock connected to the source of current.
The switch designated 3 to 4, as well as the switches designated 0 to 5 and 5 to 10 are contacted thus the light will be turned on at 3 There being a continuous circuit during this period as the hour brushes as well as the minute brushes have made continuous contacts with the segments to which said switches are connected. It may be desirous to operate the device being controlled for several hours in sequence thus the switches designating the hours are turned on. In like manner the control may be used only for five minutes by setting the switch for any five minute period most convenient. Likewise a group of switches in sequence may be set on the lower row of switches to control operations for any number of five minute periods up to one hour and by turning on groups of switches in the upper bank of switches opera- .tions may continue for any length of time in hours including continuous operation.
I do not wish to be limited to exact divisionsof time shown as it is apparent that by employing a similar arrangement to be operated'by a clock having large second hands that discs and contacts as well as the control switches similar to those shown may be made to control electrical accessories for fractions of a minute up to one minute as .well a the five minute and hour periods shown by the drawings.
Segments may also be shortened breaking the circuit for special uses not requiring varied continuous periods of operation.
I have shown the switches 3 and l of a type requiring one-quarter turn to complete the circuit and each switch is provided with a pointer except the hour switch 3, the fourth switch from i the left designated 3 to 4 and the first two five minute switches 4, in the lower row at the left designated 0 to 5 and 5 to 10. It may be seen that numerous types of switches may be employed and the designations may vary in relation to the switches and also their arrangement on the switchboard 3.
The operation of the switches 3 or 4 may be seen by referring to Figure 6 of the drawings in which I have shown the contacts 28 and 29, which are connected to the wires 22 and 23 in their open position. By a movement of the cam 30, the contact 29 is forced upwardly, completing the circuit, said cam, 30, is preferably secured to and rotated by the shaft 31 upon which is also secured the pointer (a) showing the position of the cam and the closing of the circuit, as above described.
I claim:
1. In a clock movement, an hour hand sleeve having a brush armand a pair of brushes connected thereto, a pair of insulated discs secured to said clock movement having contact segments mounted thereon in alternate relation whereby said brushes moved by said clock movement make contact with a segment on one of said discs, and before leaving said segment in their path of travel make contact with a segment on the opposite disc to provide a continuous circuit of such segments as may be connected, separate switches connected to each of the segments, hour designations adjacent each of said switches, and connections forming a control circuit including said brushes, segments and switches whereby thehour at which said circuit is to be closedcan be selected by said switches.
2. In a clock movement, an hour hand sleeve having a brush arm and apair of brushes connected thereto, a pair of insulated discs secured to said clock movement having contact segments mounted thereon in alternate relation whereby said brushes moved by said clock movement make contact with a segment on one of said discs and before leaving said segment in their path of travel make contact with a segment on the opposite disc to provide a continuous circuit "of such segments as may be connected, separate switches connected to each of the segments,'hour designations adjacent each of said switches, and connections forming a control circuit including said brushes, segments and switches whereby the hour at which said circuit is to be closed can be selected bysaid switches, a minute hand spindle having a brush arm and brushes mounted thereon, a second pair of. insulated. discs having alternate segments contacting said last named brushes, other switches connected to each of said last named segments and included with said last named brushes in said control circuit whereby said control circuit can be closed for a predetermined number of hours and/or minutes.
