. OF CHICAGO, ILLINOIS.
ELECTRIC-ARC LAMP.
SPECIFICATION forming part of Letters Patent No. 280,709, dated July 3, 1883,
Application tiled November 11, 1882.
To all whom, t may concern,.- -I
Be it known that I, FOREE' BAIN, a citizen of the United States, residing rat Minneapolis, Hennepin county, Minnesota, have invented new and useful Improvements in Electric-Arc Lamps, of which the following isa specification.
My invention relates to certain new and useful improvements in electric-arc lamps.
1o It has for its objects to produce a regular feed of the carbons; also to provide a clutch mechanism which shall be protected from dirt and'abrasion, and thus rendered more durable and perfect in its operation; and with these ends in view my invention consists of the peculiar construction and arrangement hereinafter more fully described and specifically claimed.
In order that those skilled may fully understand my invention, I will proceed to describe the constructionl and operation of the same,
referring by letters to the accompanying drawings, in which- Figure 1 is a central vertical section of so much of an electric-arc lamp as is. necessary to illustrate the features of my invention.
Fig. 2 is a cross-section of the carbon-carrier and clutch; and Fig. 3, a similar view, showing a modified form of the same.
Similar letters indicate like parts in the several figures.
AA is the frame of an ordinary lamp, provided with the usual binding-posts and side rods, BB. The upper tube, C, is secured to the top of the frame A, as usual, and within this tube moves vertically the carbon-carrier tube D, all of which is common to lamps of this class. Vithin the frame are connected the prime coils E by means of a screw, a, working through a vertical slot, b, in the side of the frame, thus providing for the vertical adjustment of the prime coils. Within the frame, and adjacent to the prime coils, are sus- (No model.)
' adjusted vertically. These springs F, being insulated, may be utilized to conduct the current to the coils G G.
Within the tube C, suspended centrally from its cap-piece by a screw-nut, c, depends a straight wire, d, within the carbon-carrier tube D, the bottom end of this rod being provided with a disk-platform, e, which is regulated by the nut c to trip the clutch f' at the proper time.
While Ihave shown the clutchf as adapted to be tripped by an interior platform, e, suspended by an. adjustable rod, d, I do not wish to confine myself to this particular way of supporting said platform, as it may be secured in position in any othersuitable manner.
The clutch f consists of a ilat block of suitable material, having vertical sides, and of a shape in cross-section to correspond with the shape of the carrier-tube D, which tube is formed with a longitudinal slot, g, at one side, to permit the passage of an arm, h., extending from the clutch f. This arm h is lifted by means of a lever, i, Fig. 4, attached at one end to the movable coils G`, and having its op- 75 posite end resting upon the floor or base of the frame. The clutch f, as will be seen, is provided with a central orifice to pass over the rod d, and said orifice is tapering, as clearly seen at Fig. l, to permit of the necessary movement of the clutch without biting said rod. To'provide against any possible sticking of the clutch, and to render it more positive, a short spiral spring, j, is employed between collars l 2, as clearly shown. It will be ob served that the clutch f is larranged within the tube, and consequently it and the surface of the tube upon which it acts are thoroughly protected from external abrasion and accu-mulation of dirt. 9o
Instead of the circular clutch shown at Fig. i 2, it may be made square, as shown at Fig. 3, or of any other form to conform to the tube D. The operation of the device is as follows: When the magnets G risc, the lever i', attached thereto, lifts the arm 7L of the clutch f, causing theedges thereof to impinge or bite against the walls of the tube D, and thereby lift the same, and when the magnets G descend the clutch f is free to also descend until its lowest Ioo lthen unlike, and in this manner the regulating movement is obtained.
Itis apparent that my improved clutch may be operated in various other ways than that shown, and Without the intervention 'of the additional lever v; but I prefer the arrangement shown.
Vhat I claim as new, and desire to secure by Letters Patent, is-
l. A clutch for electric lamps, arranged within the slotted carbon-carrier tube, in combination with a tripping-platform, also arranged WithinA said tube, substantially as described. f.
2. In an electric lamp, the electromagnets E, connected to the frame A, in the manner described,l to provide for vertical movement bodily ofthe said magnets, in combination with the armature G, mounted upon springsupports and adapted to corresponding bodily vertical adjustment, and having the shunt or differential coils Wound upon the same, substantially as and for the purpose set forth.
3. The clutch f, arranged Within the slotted tube D, and adapted to impinge against the interior of the same, in combination with an interiorlyarranged platform, e, and suitable clutclroperating mechanism, substantially as set forth.
In testimony whereof Ihave hereunto set my hand in the prescncevof two subscribing witnesses.
