JOHN GREENE AND WILLIAM Gr. SADLEIR, OF SALT LAKE CITY, UTAH.

TIME-CONTROLLED GANG-SWITCH.

Application tiled September 30, 1912.

To all whom 2'25 may concern.'

Be it known that we, JOHN GREENE and lViLLmM G. SADLEIR, citizens of the United States, residing at Salt Lake City, in the county of Salt Lake and State of Utah, have invented certain new and useful Improvements in Time-Controlled Gang-Switches, ot' which the following is a specication.

Our invention relates to time controlled electric switches, and has tor its object to provide a device operated by and in unison with a clock, whereby a switch, or any number ot switches, may be operated to make or break an electric circuit, at any hour of the day; and which is not a part of the time mechanism or so connected therewith as to injure the clock or impair its correct-ness. These objects we accomplish with the apparatus illustrated in the accompanying drawings in which similar letters of reference indicate like parts throughout the several iigures, and as described in the specification Jforming a part of this application and as pointed out in the appended claims.

Figure 1 is a front view in elevation, showing two switch units. Fig. 2 is an enlarged front elevation of the switch dial, parts cut away. Fig. 3 is a side view of the same. Fig. 1 is an enlarged side elevation of two spring' contact rods. F ig. 5 is a longitudinal section through one Fig. 6 is a side elevation of the lever controlling and moving mechanism, parts cut away. Fig. 7 is a .frontview of the contact lever with front plate removed. Fig. S is a plan view of the lever moving rock-shaft and spring. Fig. 9 is a plan view of the wrist plate and pin, and a portion of the contact lever. Fig. 10 is an end elevation of the same. Fig. 11 is an elevation oi' one of the contact posts, and a portion in section of the support therefor. Fig. 12 is a plan view of the same. Fig. 13 is an enlarged front elevation of the stop disk and crank disk.

lt is often desirable to turn on electric energy at night and at other times during the day to be used for a short time only; and in order to use said energy for a limited time and to turn it ott at the end of that time, personal attention is usually required to operate the switch to make and to break the circuit. 1n other places a number ot such circuits are needed and used, so much so that an attendants entire time is required to Operate the switches. Our invention is to Specification of Letters Patent.

Serial No. 723,228.

supply a switch or any number of switches to turn on or off electric currents at any predetermined time in the twenty-tour hours of the day, and in which the timing part of the apparatus may be placed at such distance trom the switch mechanism that any jar or movement thereof will not affect or injure the time mechanism, said mechanisms coacting to produce the desired result. Also in our apparatus one of our time mechanisms will regulate almost any number of individual switch units.

The preferred form of our apparatus is shown in the drawings and consists of an ordinary eight day clock A mounted in a case B. A gear wheel 2 is journaled in the frame of said clock and the teeth of said gear wheel mesh with a gear wheel, (not shown) that is secured on the hour hand shaft ot said clock, and with an idler gear 70, which is journaled in a switch dial C. Said dial C is mounted in said case B adj acent said clock and consists of a base plate 3, and standards 1. To the intermediate portion of said standards 4L is fastened an annular hour disk 5, having the numbers 1 to 12 placed clockwise thereon in a circle with 12 and 12 at the top and bottom, and with the numbers 1 to 11 consecutively placed in a circle therebetween. Over the top number 12 the word Noon is printed and below the bottom number 12 the word Midnight. Adjacent the number 6 to the right,v

the letters P, M. are placed and adjacent the number G to the left the letters A. M. are placed. Concentrically within said disk 5 is mounted the adjustable rotative disk (i. Said disk 6 has forty-eight radial lines 7 thereon equally spaced apart, and in said lines 7, holes 8 are provided in a circular row, concentric with the outer edge of said disk 6. Any number' ot rows of said holes may be provided, two being shown in the drawings, a row for each of the switch units which are described hereinafter. The outer row of holes are numbered 8 and the inner ones 9 and their use and purpose will be explained hereinafter. Within the circle formed by said holes 9 the numbers 1 to 12 are placed in a circle, reading trom 12 to 1 and fromY 12 to 1. Each of said numbers being in alinement with one of said lines 7 and also the word Noon is printed adjacent one oit the numbers 12 and the word Midnight adjacent the other number 12. The word Evening is printed adjacent the .figure 6to the right and the word Morning adjacent the figure 6 to the left. For convenience in setting the dial and the clock in time with each other a pointer 10 is fastened on said disk 6 in alinement with the word Midnight. On the top of said standards l are fastened the braces 11, radially disposed and forming a top bearing at their inner ends for a central shaft 40. On the lower portion of said shaft 40 is secured the dial gear 71 which meshes with said idler gear and by which motion is imparted to said disk G. On one of said braces 11 a block 12 made of insulating material is secured. In said block 12 are fastened the contact rods D each consisting of a severed and hingedly connected metal bar 13.

Secured to the two portions of the'bar 13 is a spring 14, by means of whicl said bar is normally held straight, but may be bent on its hinge as shown in dotted lines in Fig. l5. In said holes 8 and 9 detachable contact. plugs 16 are to be inserted. @n the lower portion of said metal bar 13 is fastened the insulating plate 15, provided 'thereon to prevent an electrical contact when said har 13 first strikes against said plugs 16. Hinged to the lower edge of each of said bars 13 is the spring held contact plate 17 which is provided thereon to complete the electrical circuit but only for such a short period of time as will enable a battery or other source of electrical power to energize a magnet or solenoid 18, which is in the electrical circuit embracing a source of electric energy, that shown being a battery 19. Said battery 19, magnets 18, contact post D 4and, the disk G are electrically connected by the wires 2O when the circuit is completed by the contact of the plate 17 with one of the plugs 16. Adjacent said magnets 1 8 is a lever controllingl and moving mechanism E consisting of a base plate 21 and top plate 22, rigidly spaced apart. and held in place by the standards 23. lvfounted between the said top plate 22 and the base late 21 are the gear wheels 24, the teeth of both of which mesh with the pinion 2V, which is mounted on the shaft 26. Said gear wheels are run by a spring 34 secured on the shaft of each. On said shaft 26 is mounted and rotated thereby the stop disk 27 and; the crank disk 28. In the peripheral edge of the said stop disk 27 are cut the slots 29 diametrically opposite and in which a bar 30 is made to engage when contiguous thereto. lithin each of said slots 29 is fastened a spring` 1, normally closing the disk 27 is free to rotate, with its axis, said g shaft also rotating. An arm 32 of said bar 30 engages the fan which is connected with a fly wheel 33 of said lever moving and controlling mechanism E. Int-ermeshing gears similar to a clock tain connect said fly wheel 33 and said shaft 26. Motion imparted to said shaft 2G by the spring 3-1@ will be controlled by said bar 30, and when said shaft 2G is rotated the disks 27 and 28 will be revolved. In the face of said crank disk 28 is fitted the crank pin 36 which is made to operate in a slotted opening 37 that is cut in a pitman 38. Said pitman is pivoted on a disk crank 58. Adjacent. said lever controlling and moving mechanism E is mounted the lever case F, consisting of a front plate 50 and a back plate 51, spaced apart and securely held in place by the standards 52 which are T-shaped and have depending lugs by which said lever case is secured in'place. Pivoted to the back plate 51 is the V-shaped lever 53, having a weight ball 5a fastened on the apex end thereof to equalize the weight of an extended arm 55. Another arm 56 of said lever is extended to engage one of said standards 52 to limit the upward throw of said lever 53. Journaled in said plates 50 and 51 is a rock-shaft 57, having one end extended outwardly through said plate 50 and on which a disk crank 58 is fastened. Said rock-shaft is placed between the arms of said lever and one end of a spring 59 is secured to said rock shaft 57 and the other end is fastened to the said lever 53 opposite the apex thereof. Gn the free end of said lever arm 55 is pivoted a wedge-shaped contact GO by means of a wrist-plate 59 and wrist pin G1. Said wedge-shaped contact is made of metal and when operated is to be brought in contact with V-shaped metal contact posts G2, each of which is formed to engage the full face in cross section of said wedge-shaped contact 60, thus enabling us to secure a wedge contact with the minimum of friction. The wires carrying the current to be controlled are secured to the binding posts G3.

In the operation of our apparatus the said switch dial C is set in time with the clock by turning` the said disk G until the said pointer 10 points to the same number on the hour disk 5 that the hour hand of the clock indicates is the time of the day, that shown being practically 12 oclock. Fractions of the hour may be shown by other radial lines 7, half hours being all that are shown in the drawings. This adjustment sets the clock and switch dial together and wishing` to turn on an electric current at four oclock p. m. one of the contact plugs 1G is inserted in one of the holes 8 in the radial lines 7 which is in alinement with the number 4 P. M. on said disk 6. lf the current is required for seven hours period of time another contact plug 1G is likewise inserted in the hole 8 opposite the number 11 P. M. on said disk 6. The ruiming of said clock A until 4 oclock will b v means of the gears and 71 turn said disk ti until the said first placed contact plug 1G will engage the insulating plate 15 on one of sai-d bars 13. A. continuation of the movement of said clock A will rotate said disk G, and said bar 13 will be bent on its hinge and assume somewhat the position shown in dotted lines in Fig. 5. 1n this position said bar 13 will slide across the top of said contact plug 1G, and the metal plate 17 will be in touch with said contact plug 1G for an instant. This will complete the electric circuit over the said wires 2O and the magnets 18 will be energized and the armature 31 will draw the bar 30 from the slot 29. The spring 1 will close the entrance to said slot 29 until the disk 27 is rotated. The arm 32 will be raised from it-s engagement with said fan 35 and the mechanism E will be set in motion. The disks 27 and 28 will be rotated and the upper end of said pitman 38 will be moved to the position shown in dotted lines in Fig. 1. lVhen the said crank pin 3G moving' as it does in the slotted opening 37 reaches the bottom of said slot the pitman 3S will move the rock-shaft 57 to the position shown in Fig. 7. and the said rockshaft 57 will by contacting with said arm 56 move the lever 53 on its fulcrum pivot 72, and the arm will be depressed to the position shown in Fig. 1. This will bring the wedge-shaped contact 60 within the walls of the V-shaped contact post 62 and complete the electrical circuit. rllhe lever controlling mechanism E will continue in motion until the other of said slots 29 is adjacent the lower end of said bar 30, which bar will strike the end of said spring 1, and move it. fi'om over said slot 29 and said bar which has been sliding on the peripheral edge of said disk 27, will drop into said slot and the arm 32 will engage the said fan and stop said mechanism E. hen said clock A has rotated said disk 5 until said contact posts D are in engagement with the other of said contact plugs 1G which will occur at 11 ocleck p. m. said mechanism E will be again set in motion and thereby7 the said lever arm 55 will be raised, the switch operated and the circuit broken. 1f said current has been used for lighting purposes the lights will have been turned on at i oclock and remained on until 11 oclock p. m. Another current may be controlled by similar contact plugs 1G being inserted in said holes 9 and another set of wires 20 connected with the other of said contact posts D, and in circuit with another similar lever controlling' mechanism E and lever case 1l" with the connected parts.
