ELECTRIC SWITCH AND CUT-=OUT.

SPECIFICATION forming part of Letters Patent No. 529,595, dated November 20, 1894.

Application filed September 24, 1894. Serial No. 523,869. (No model.)

To all whom it may concern.

Be it known that I, JOHN C. CASSIDY, of the town of East Orange, State of New Jersey, have invented a new and useful Improvement in Electric Switches and Out-Outs, of which the following is a specification and description. I The object of this invention is to show an improvement upon the switch and cut-out de scribed in my application for a patent for an electric switch and cutout, filed August 11, 1894:, Serial No. 520,007. In this specification, I desire to show a simpler device for securing the end attained in application, Serial No. 520,007. V

In the accompanying drawings, Figure 1 represents a front view of myim proved electric.switch and cut-out. Fig. 2 shows a section thereof on the line 2-2. Fig. 3 shows a section of Fig. 1, on the line 3-3 thereof. Fig.

4 shows a section on the line 2-2 of Fig. 1 with some modifications.

Similar letters and numerals refer to corresponding parts in the various figures.

A represents a frame made of any material, to hold the various parts making up my improved electric switch and cut-out. Said frame A carries at one end the screw F, by means of which the switch is attached to the chandelier or electrolier. At its other end is a collar D, threaded on the inside, so as to receive the rotary shaft 0; said frame A, screw F and collarD forming one piece. Attached to said rotary shaft 0 is a finger piece B, havmg a neck W, which is threaded so as to allow 1t to be screwed on to the rotary shaft 0, and which finger piece B is held in place and fastened to said rotary shaft 0, by means of the screw T, which is screwed through the opening V on to the shaft C.

X is ablock of insulating material, rigidly attached to the top bar A of the frame A by screws or other well known devices said block X carrying on one-half of its periphery, a contact piece X, of conducting material, which contact piece X is attached to the said block X, by means of the screws. 1, 2, 3 and 4. Through the center of said block X and penetrating through block X, is an openingF'. The rotary shaft 0 has a hearing by means of this opening F through the block X, its end bearing in the screw F. I is a collar placed between the block X and rotating block R.

R is a rotating block of insulating material, fastened to the rotary shaft 0 at Y, by means of the screw Y. Said wheel R hason its front, and covering one-half of the circumference of said wheel R, a contact piece S, of which of conducting material, and the upper S presents a corrugated surface of conducting material; it being understood that the said contact piece S presents the corrugated surface S immediately above the smooth surface R, both on the same side of the peripheryof the rotating blockR.

J is a block of insulating material, placed between the wheel R and the block E.

E isa block of insulating material, fastened to the arm A.of the frame A.

H, H, H, H ,'H and H are contact springs fixed rigid in any of the ways described in my former application, Serial No. 520,007, to the said insulated block E, by means of the screws G, G, G, G G and G said contact springs H, H, H, 11 ,11 and H being made of any well known conducting material.

5, 6, 7, 8, 9 and 10 are contact screws. The said block X carries on one side of it, a contact spring L, which said contact spring is made of any conducting material, and of such length that it will touch the corrugated surface S of the contact surface S of the wheel R. Said contact springL is held in position by means of the screws 1 and 2. Electrical connections are made through the screws 3 and 4, the contact piece X, the contact spring L, contact surfaces R S, springs H, H, H, H H and H and screws 5, 6, 7, 8, 9 and 10. The screws 5, 6, 7, 8, 9 and 10 may be dispensed with, and connections made by means of the screws G,.G, G", G G and G In this construction it will be observed that the circuit is completed, when the screws 5, 6, 7, 8, 9 and 10 or the screws G, G, G, G G and G springs H, H, H. H H and H are, or any one of them, is in engagement with the contact piece S, and said contact piece is engaged with the spring L, and through the surface X, with the screws 3 and 4:. The contact spring L acts not only as a connecting medium, but holds the wheel R in place when said contact spring L engages any of the corrugations S of the surface S. The contact pieces H, H, H, H

the lower part R presents a smooth surface H and H can be connected each with a single lamp or can be connected with a series of lamps.

The particular construction shown in Figs. 1, 2 and 3, shows the contact spring L resting on the corrugated part S of the surface S, and also shows the springs H, H, H, H H and H resting on and over the plain surface R of the surface S of the wheel R.

Another method of making the contact, is shown in Fig. 4, in which the spring L, instead of riding over and on the contact surface S, is bent so that it touches the top L of the contact surface S, and the contact spring H is bent so that it touches the bottom L of the contact surface S of the wheel It, and in that manner makes connection. Of course in this construction, in order to allow for the wear on the springs L and H, and what slight abrasion there may be in the material of the springs L and H, by the constant rubbing, I have deemed it necessary to insert compensating springs, in the form of the springs L and L, the spring L taking the place of the block Land spring L, the place of the block J; the said springs L and L" being wound around the rotary shaft 0, said spring L being fastened either to the wheel R or the block X, and the spring L being fastened either to the wheel R or the block E.

The operation of my improved electric switch and cut-out, is as follows: The rotary shaft O being firmly connected at its one end to the finger piece 13, and bearing through the neck D, bar A, blocks E, I, J and wheel R, block X, bar A and screw F, or when the springs L and L are used, through the springs L and L in place of the blocks I and J, will, when it is turned,cause the wheel R to revolve, while the other parts will remain rigid, so that if the rod G is moved in either direction by means of the finger piece I3 or other well known means, it will carry with it the wheel R. The result of this will be that when the red C is turned in any direction sufficiently either to the right or to the left, a circuit will be made or broken, according as the contact surface S or the remaining insulated portion R of the wheel R is brought in contact with the springs H, H, H, H H and H and the spring L; the said wheel R being covered for one-half of its periphery with the contact surface S. hen said wheel R is caused to revolve one-half of its periphery, it will make a complete con nection between all of the springs H, H, H", H 11* and H and the spring L, so that all the lamps of the chandelier or electrolier will be lighted. In order to turn out all of the lamps, it will simply be necessary to turn the finger piece 13 farther in the same direction, carrying the wheel R with it, so that theinsulated surface R of the wheel R will be between the springs H, H, H H", H and H and the spring L. This will break the circuit. Consequently the lamps will be extinguished.

As shown in my previous application, Serial No. 520,007, the springs H, l1,ll, H II and H and the spring L should be made of such width that when the contact suaface S of the wheel R is not turned so as to break contact with all of the springs H, H, H, H H and H arcing will be prevented. The manner in which one or a series of these lamps may be lighted, is simple and is as follows: Let us suppose that the wheel R has been so turned, that the full insulated surface R is above all of the springs H, H, H, H II and H con tact will then be broken. Inasmuch as the contact piece S covers onehalf of the periphcry of the wheel R, it will only be necessary to turn the finger piece B to the right, and it will readily be seen that by turning the finger piece B,so that a portion only of the surface S comes between one spring H and the contact spring L, a circuit will be made, and the lamp or series of lamps connected with the spring ll only, will be lighted. If it is desired to extinguish the lamp or series of lamps connected with the spring H, it will only be necessary to reverse the motion. \Vhen it is desired to light two lamps or two series of lamps, the finger piece B may be turned, so that the contact piece S of the wheel R will come above the springs H and H, and through L make a circuit, and the lamps or series of lamps connecting with the springs H and H will be illuminated, and in the manner heretofore described, can be extinguished; and this principle can be carried forward, until four, five or six lamps can be illuminated, and one or a smaller number, or all of them extinguished by reversing the motion; or if all the lamps be lighted, and it be desired to extinguish the lamps connected with H or with H and H only, it will but be necessary to further turn the finger piece B to the left, so that the contact piece S will be removed from above H" and H and thus contact broken, and the lamps extinguished. All these lamps may be again illuminated by simply reversing the direction. Of course, the collars I and J may be displaced by any other well known means, tending to keep apart the block X, wheel R and block E, and I do not intend to limit myself to the precise methods herein shown, but I desire to cover by my invention, the mechanical equivalents of any of the parts or methods herein described.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. An electric switch and cut-out, consisting of a frame A, having a bar A, to which is rigidly fixed an insulated block X, said block X carrying a contact surface X fastened thereto by means of screws 1, 2, 3 and 4-, said screws 1 and 2 also holding in place a connecting spring L, said connecting spring L being of conducting material, all in combination with an insulated collar I and wheel R, having an insulated surface It and a contact surface S, one-half of which contact surface is corrugated and the other half smooth;

said corrugated surface S and smooth surface R being of one piece, in combination with a collar J and an insulated block E, carrying contact pieces H, H, H", H H and H said contact pieces H, H, H", H H and H being fastened to said block E by means of the screws G, G, G, G G and G said block E being fastened to the arm A of the frame A, said arm A" carrying a neck D in combination with a rotary shaft 0, and a finger piece B, so arranged, that said rotary shaft 0 will cause the wheel R to revolve, so as.to present the insulated surface R of the wheel R, or the contact surface S of the wheel R to the connecting springs H H, H, H", H H and H substantially as hereinloefore described.

2. An electric switch and cut-out, consisting of a frame A, having a bar A to which is rigidly fixed, an insulated block X, said block X carrying a contact surface X fastened thereto, by means of the screws 1, 2, 3, and 4, said screws 1 and 2 also holding in place a connecting spring L, said connecting spring L being of conducting material, all in combination with a wheel R, having an insulated surface R, and a contact surface S, one-half of which contact surface is corrugated and the other half smooth, said corrugated surface S and smooth surface R being of one piece, said block X and wheel R having inserted between them, a spring L in combination with an insulated block E, said wheel R and block E having inserted between them, a spring L", and said block E carryingcontact pieces H, H, H", H H and H which contact pieces are fastened to said block E by means of the screws G, G, G", G G and G said block E being fastened to the arm A" of the frame A, said arm A carrying a neck D, in combination with a rotary shaft 0 and a finger piece B, so arranged that said rotary Shaft C will cause the wheel R to revolve, so as to present the insulated surface R" of the wheel R, or the contact surface S of the wheel R to the connecting springs L, H, H, H", H H and substantially as hereinbefore described.
