SPECIFICATION forming part of Letters Patent No. 497,756, dated May 16, 1893.
Application filed January 17, 1893. Serial No. 458,741. (No model.)
.To all whom it may concern: metal brush 7 is secured to the base of the Be it known that we, ERNST \VOLTMANN casing, its free extremity being continually and HARRY A. 'lRIG-GS, citizens of the United in contact with the face plate of the disk.
States of America, residing at Denver, in the Two other brushes 8,8 are also secured to the H 5 county of Arapahoe and State of Colorado, casing at one extremity, while their opposite have invented certain new and useful Imextremities engage the edge of the disk provements in Circuit-Switches; and we do whereby as the disk is rotated they alternatedeclare the following to be a full, clear, and ly engagethe exposed insulating parts and the exact description of the invention, such as metallic contact parts comprising the edge of [0 will enable others skilled in the art to which it the disk as explained above.

The dog 9 is held in 25 receptacle being removed. Fig. 2 is a side engagement with the edge of the disk by a View of the same, the casing being open to small leaf spring 13 having one extremity show the mechanism within. Fig. 3 is a diamade fast to the push bar. This bar 10 cargrammatic view illustrating the circuit necries a projection 1O" which engages a leaf 8o essary for controlling one or more lamps from spring 14 made fast to the casing at one ex- 30 two different points. In this case two switches tremity. The function of this spring is to reare required. Fig. 4 is a similar view showturn bar 10 to its normal position after it has ing a single switch in circuit. Figs. 5 and 6 been thrust forward to its limit of movement are perspective views showing the two parts or sufiiciently to turn the disk the length of of the rotating disk in detail. one tooth or notch on its edge.

In one side,5*, of this wire 16, binding post 17, brush 7 to the face 0 casing which we will term the base, is pivoted plate of the disk and thence through one of a two part toothed disk 6. This disk is comthe overlapping contacts of this plate to the posed of insulating material 6 and an outer brush 8, binding post 18, wire 19 to the lamp portion 6of metal or other suitable conductor 20, and thence through wire 21 to the other of the electric current. This outer metallic feed wire 22, the circuit being closed and the 45 portion is of such construction that the inner lamp lighted. To put out the lamp it is only insulating portion is partlyexposed and partly necessary to give the disk another partial rocovered on the edge of the disk. These eX- tation by actuating the push bar 10, when the posed parts of the disk alternate regularly brushSwill engage one of the exposed insulatwith the metallic covered parts. One face of ing parts of the disk, breaking the circuit.
50 the disk is also covered with the metallic part, When two switches are employed and the this face plate being formed integral with the light controlled from two points the path of contact parts overlapping the disks edge. A the current, assuming that the two brushes at the right in Fig. 3 are in engagement with the contact parts of the disks edges, will be as follows: from feed Wire through branch wire 16, binding post 17, brush 7, the face plate of the disk and brush 8, binding post 18 of one switch, then through Wire 24 to binding post 18 of the other switch, and thence through brush 8, the face plate of the disk, brush 7, post 17, wire 19, lamp 20 and wire 21 to the feed Wire 22. Now if either switch disk be given a partial rotation resulting from a single push of the bar 10 the circuit will be broken and the lamp extinguished, since in this case the corresponding brushes 8 of the two switches will engage opposite parts of the disks edges, that is, contact and insulating parts respectively. Now when these brushes are in these positions if either disk of either switch be given a partial rotation, the circuit will be again established, the current passing in one case through wire 24 and one pair of brushes 8, while in the other case through wire 23 and the other pair of brushes 8.
Having thus described our invention, What We claim is 1. In a circuit switch the combination of the make and break mechanism consisting of a two-part rotating disk composed of connecting and insulating material, and two contact brushes engaging the disks the parts of which are so arranged that one brush is continuously in contact with the conducting ma terial while the other brush is alternately in contact with the conducting and insulating parts, and a single push button orbar for operating the same, substantially as described.
2. In a circuit switch the combination of a rotating ratchet disk composed of insulating and conducting material, the latter consisting of a plate attached to the insulating material in such a manner that the conducting and insulating material are alternately exposed on that part of the disk engaged by one of the contact brushes, two brushes, one of which alternately engages the contact plate while the other is continuously in contact therewith, and a single push button carrying a dog for operating said disk, substantially as described.
3. In a circuit switch the combination of a two-part rotating contact" disk composed of conducting and insulating material, three contact brushes engaging said disk the construction of which is such that one of the brushes is continuously in contact with the conducting material while the other two are alternately in contact with the conducting and insulating parts, and a single push bu tton or bar for operating the disk, substantially as described.
In testimony whereof We affix our signatures in presence of two witnesses.
