To @ZZ whom it' may concern,.-

Be it known that l, FRANKBELAND, a citi-- zen of the United States, residing'atI Cairo, in the county of Alexander and State ef'lllinois, have invented a new and useful Electric Time Cut-Gut, oi which the following is a specification.

This invention relates to electric time cnt outs; and it has for its object to provide certain improvements in'automatic cut-outs ern- 'ployed 4for holding an electric circuit open or closed any length of time, and to be used in connection with electric lighting systems, motors, dac., so that the apparatus may be brought into use and cut-out of use automatically, at stated intervals, or periods of time. To this end themain and primary object of-this invention is to simplify the construe tion of time cut-outs, while at the same time providing'a cut-out having every adjustment necessary to provide-for the proper distribntion of the electric current,whether for lightingor otherjpurposes. i

With these and 'other objects in view which will readily appear as the nature of the in` vention is better understood, the same consists in the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawings: -Figure l is a front elevation of an electric time cutoutconstructed in accordance with this invention. Fig. 2 is an enlarged transverse sec- `tional View thereof, showing the clock mecharrisxn and more lclearly the method of connecting the contact segments with the cutout or short circuit ring and also with'the working'circuit rinv. Fig. 3 is a plan view of the cut-out dial showing the several rings thereof and the proper circuit connections. Fig. 4 is adetail in perspective of one of the shiftable contact segments and its attaching foot. Fig. 5 is a front elevation ofthe cutout modified-for multiple work.' Fig. 6 is a detail in perspective of the insulator cut-out ring employed for multiple work.

Referring to the accompanying drawings, A represents a' clock mechanism frame in which'is mounted the ordinary clock niecirn anism, which, in the present invention isnt that character adapted to run continuously for twenty-four hours at one winding theren ont the working circuit from. i cure the same resnit for ontw.`

`apparatus ont of use, l ernpoya cut-cut ot',y and so construcitedA that the main shatter arbor O,`therect, wilL make one revolution in twenty-four hours. This is effected without anychange Whatever the construction of the clock mechanism, out a twentyi'onr hour movement is preterahfle for use in conneo tion with apparatus et tors character.

Secured to one side of the trame A, is the cut-out dial D, formed et any suitable insulating material and 'provided W a central opening E, through which projects 'the 'outer endof/the main strait or arbor il, and said insulator dial D, is :further provided in its outer face with a concer 'c series of circular grooves F, the inner grooves which accommodate theJ continnons central charging ring G, which has a wire connection g, with one ofthe main circuit binding pests li, to which is adapted to'be connected one termin nal of the main supply circnit 1mi?, said binding post to which the Wire g', is connected may for the saire ci clearer understanding be called the positive or charging irepresent one hour on the dial plate, as Will be more fully understood. in connection with the other parts ot' the cut-ont to be pret-ientlyv described.

The inter i.ediate embout ring I, is electrically connected hy short circuit Wire ,-with the other binding; post H of the main supply circuit vluz?, so thatwlien said cnt-out ring and the central charging ring are in one circuit, a short circuit completed from. one post li, to the other, in order to cut e, and to sethe entire switch L, arranged in the short switch. circuit 1?-1, theternlinals ot which. are connected directiy to theadjacent posts ii. The other outer Working circnit rii Cl, if; connected. by the wire t7`,With one of the binding posts seance ing circuit is renderedactive.

Shiftable contact segments N, are adapted to be.I connected with either of the .rings .I and VJ, at any of their subdivided points, and said contact segments have beveled ends n adapted l to be slightly separated from the corresponding ends of the adjacent segment, and such contiguous segments provide when the entire series of segments are in position a circular contact ring or path for the brush devices to be presently referred to, and each of said contact segments is -pivoted at its center as at fn',

A'to the outer angled extremity of. an angled attaching foot O. The angled attaching feet O, are angled at both ends or extremities so that the inner ends can be readily shifted from one ring tothe other when changing or adjusting the intervals at which the working circuit is to be brought into play, and the ostanding feet O, are rembvably attached to either ot the rings I and J, by means of the attaching screws P, passing through the inner ends of the feet and engaging the threaded openings K, in such rings.

vSecured to and 'insulated from thel outer end of the main shaft or arborC, of the clock mechanism is -the traveling brush arm Q. The brush arm Q, has an inner inwardly disposed arm extension R, to which is attached one end of thespring collectingbrush S, which makes a constant and permanent contact with the central charging ring G, while to the outer extremity of the arm Q,is pivotally attached the circuit brush T, normally held in contact with the circuit or path of slightly separated contact segments by means of the vspring t, secured thereto and to the arm, and such circuit brush is curved gently, or of such a shape, so as to span the spaces between the segments when trailing thereover. a

Now from the foregoing it is thought that the construction and operation of the herein described time cut-out will be readily apparent to those skilled in the art.

Assuming the contact segments to be arranged a'sillustrated in Fig. 2, twelve of such seginents are attached directly to the o'uter working circuit ring J, while the other twelve are connected to the intermediate cut-ont or short circuitring I, so that there will be a period of twelve hours duration in which the working circuit is active, and twelve hours when it is cut out. 'Vith this arrangement of contact segments it will be apparent that when the circuit brush T, is traveling over the segments connected to the Aouter ring J, the circuit is completed from the central charging ring G, through the brush arm, the ring J, the connection j, and the working circuit 3 4, so that such circuit is active and in use during the interval while the circuit brush v is traveling over thesegments connected therewith.' n, When the circuit brush T, reaches the segments connected with the intermediate cut-out ring I, the electric current is short cir'cuited through said intermediate ring and over the connection/i, so that the workingcircuit is cut-out from use.

It will be apparent that any arrangement ofthe contact segments may be observed, so

that the workingcircnit can be rendered active, automatically, at any stated time or for any. duration of time according to the Acharacter of work required of the working circuit,

and by reason ofl the pivotal connection of the contact segments with their attaching feet, the .circular continuity of such segments` is never broken, because in shifting the con nection from one of the rings to the other, it

.is simply necessary to hold theisegments stationary and turn the angled attaching feet from one'ring to the other, it of course being understood that the openings K, of each ring are immediately adjacent to e'ach other.

Many dispositions and arrangements of the contact segments and various modifications of the cut-out may be observed, and I will have it understood that changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle o r sacrificing any of vthe advantages of this invention, particularly since the construction herein-described is employed especially for series work, and it is obvious that it is necessary to employ the cutout for incandescent and general multiple vided with a-single cut-out notch V, formed deeply therein in order to provide for the instantaneous opening of the circuit at the time desired, and is provided with an inclined side YV, .leading out to the outer edge of the said raised ring. scribed the construction is identical with that hereinbefore described, with the exception of the substitution of the ring U, and the non- In the modification just de-' IOO IIO

employment of a supplemental short circuit,

so that the circuit is always closed through the central ring G, and the outer working circuit ring J. The attaching feet O, which carry the shiftable contact segments at their outer extremities, are adapted to be removably attached at any ot' the regular intervals on the outer working circuit ring J,and wherever these attaching feet are attached, the segments carried thereby are disposed directly over and beyond the outer track edge thereof.

In the multiple construction just described, in order to have the lamps or motors cut in for any stated period it is simply necessary to attach the segments to the working circuit ring at the desired point, so that the circuit brush 'l`,will contact therewith when it reaches that point. Now it will be apparent that while the clock is runningproperly, andthe circuit brush contacts with the contact segments at the point where they are located, the circuit is closed directly through the central and outer rings over the working circuit. New the cutout notch V, in the cut-out ring, is adapted to be disposed immediately beyond the last segment with respect to the travel of the brush arm, so that as the brush T, leaves such last segment, it immediately drops into the cut-out notch V, whereby the circu it is opened instantaneously, so as to cut out the lights or motors which are included in the working circuit, without shifting the currentover a short circuit as is necessary or expedient for series work as hereinbefore described. The brush T, climbs out ot' the notch V, over the inclined side lV, of such notch, and then travels around on the outer edge of the raised contact ring until it again comes in contact with the segments.

Having thus described the invention, what is claimed, and desired to be secured by Letters Patent, is- A 1.
