HANS J. MULLER, OF NEW YORK, N. Y., ASSIGNOR TO HIMSELF AND ALEXANDER LEVETT, OF SAME PLACE.
APPARATUS FOR CREATING VACUUMS IN INCANDESCENT-ELECTRlC-LAMP GLOBES.
SPECIFICATIONforming part of Letters Patent No. 266,303, dated October 24, 1882.
Application filed April 11, 1882.
To all whom it may concern:
Be it known that I, HANS J. MULLER, of the city, county, and State of New York, have invented a new and improved Apparatus for Creating Vacuums in the Globes ot' Incandescent Electric Lamps, of which the following is a full, clear, and exact description.
The object of my invention is to facilitate creating vacuumsin the globes of incandescent electric lamps, and to facilitate sealing these lamps after the vacuum has been produced.
The invention consists in the combination, with an air-pump, of a tube containing a piston and adapted to receive a quantity of mercury, and plugs at the top and bottom of the mercury, which plugs and mercury can be forced into the seal-tube of the lamp after the air has been exhausted, the lower end of this seal-tube being held air-tight on the upper end of the tube containing the plugs and the mercury. The apparatus is provided with a mercury-filling tube combined with a sliding piston for opening and closing it, and with a branch tube containing a piston for opening and closing the end of the tube leading to the air-pump. This tube is provided with a receptacle for collecting the mercury which accidentally passes into the air-tube.
The invention also consists in the arrangement and combination of parts, as will be fully set forth hereinafter.
Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.
Figure l is a longitudinal sectional elevation of my apparatus for creating vacuums in incandescent electric lamps. Fig. 2 is a plan view of the clamp for holding the seal-tube of the lamp in the apparatus.
The plug B fits into the neck A of a bulb or globe, A, and is attached to a base, D. A sealtube, J J, which is contracted at theupper end, projects from the bottom of the plug B through the base D, all as has been fully de scribed in the specification of this lamp in another application. A bent arm, I), having its upper end scrcwthreaded, is attached to a table or frame, 0, and on this arm I) the base (No model.)
D of the lamp is screwed, as shown. A vertical glass tube, d, of precisely the same inner diameter as the tube J of the lamp, contains a piston, 0, attached to the piston-rod], passing through a stuffing-box, g, screwed on the lower end of the tube d. A horizontal tube, h, branches ofi' from the tube (1, near its upper end, and from this tube h a tube, 7', provided with a cock, j, branches off and leads to an airpump, it, of some suitable construction, which pump is provided with a gz'ige, Al The tube It contains a piston, l, slightly longer than the distance in the tube h from the tube i to the tube (1, which piston is attached to a pistonrod, m, passing through a stuffing-box, n, on the outer end of the tube It. A mercury-receptacle,0, in communication with the tube h, is secured on the top of the same. A horizontal tube, 11, branches off from the tube (7, near the lower end of the same, and from this tube 19 a tube, q. open at the upper end,cxtends upward. The tube contains a piston, r, slightly longer than the distance from the tube 61 to the tube g, which piston r is attached to a piston-rod, s, passing through a stufting-box, t, on the end of the tube 19.
A receptacle, u, provided at the bottom with a cock, '0, is suspended from the lowest part of the tube "6. A clamp, 10, having the ends of thejaws curved, and provided with rubber packing 0c, is provided with a clamping-screw, y. The ends of the jaws of this clamp are curvedin such a manner as to fitclosely against.- the tubes d and J. The length of the tube (1 fromits inner bottom surface to the inner bottom surface of the tube h must be exactly equal to the length of the aperture J in the tube J.
and plug 13.
The tubes (1 and q are provided with zeromarks on the same level, thedistance from this zero-mark to the lower edge of the plug K being exactly equal to thedistance from the righthand edge of the opening of the tube (1 to the left-hand edge of the opening'of the tube q.
The operation is as follows: The lamp is screwed on the arm I), and thelower end of the tube J is placed on the upper end of the tube (1 anti packing material zis placed between the meeting ends of the tubes, which are held together by the clamp was shown. Before uniting the tubes a plug, L, of gutta-percha or rubber, is pushed to the bottom of the tube (1, and a like plug, K, is pressed into the tube (1 until its upper edge is flush with the lower edge of the aperture of the tube It, as shown. The pis ton 0' is drawn outward until the lower end of the tube q is open, and mercuryis poured into the tube (1 until it is on the level of the zeromarks. The piston risthen pushed back aml forces the mercury in'the tube 9 into the tube (7, causing the mercury in the tube (1 to rise up to the bottom of the plug K. The piston l in the tube It is then withdrawn until the upper end of the tube '2 is open. Then the pump 7; is operated to exhaust the air from the globe A until the gage in the pump It: shows zero. Then the piston 1 is pushed forward until its end is tlush with the side of the aperture of the tube (7, to prevent the escape of mercury into the tube it. The pistoirrod f is then pushed upward, whereby the plugs K and L and the mercury M in the tube til will he torced into the tube J, the plug K being pressed into the up per contracted end of the aperture J. These plugs K and Land the mercury ett'ectuallyseal the lamp and prevent the access of air. The lamp isthen unscrewed from the bracket-arm I), and another-lamp, which is to be exhausted, is screwed on this arm. The mercury which aecidentally passes into the tubes hand i is collected in the receptacle a, and can be drawn off at proper intervals by opening the cock 1*. The mercury in the receptacle 0 forms a close joint for the piston and rod in the tube It. Any number of the above-described apparatus can be combined with one air-pump.
It is obvious the invention may beused with equal facility for exhaustingother vessels than lz'tmpglobes-as, for instance, jars t'or containing fruit or other edible substances.
.llaving thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. An apparatus for creating a vacuum,
'made substantially as herein shown and de scribed, with a tube for containing mercury,
and plugs below and above the mercury, aml with devices for forcing the plugs and the mercury into the seal-tube of a lamp, which sealtube is to be held on the end of a tube containing the plugs and the mercury, as set forth.
2. In an apparatus for creating a vacuum, the continuation, with an air-pump, and a tube which communicates with the lamp-bulb, and a suitable device for cutting oil" coniununication with the pump after the air has been exhausted, of a pistomc, having rod f, for use in forcing a suitable seal into the said lamp-tube, substantially as shown and described.
3. In an apparatus for creating avacuum, the COll'lblllZlblOll, with an air-pumpand a tube communicating with the lamp-tube, of the branch tube It, the piston l therein, the piston 0, having rod f, and the seal consisting of mercury-column M and plugs K L, as shown and described.
4-. In an apparatus for creating a vacuum, the combination, with the airpump and the tube J, which communicates with the lampchaznber, the tube It, and piston 1, working in the latter, of the mercury receptacle or bulb 0, connected with tube It in rear of said piston, to operate as specified.
5. In an apparatus for creating a vacuum, the combination, with the tube (7, the piston c, the piston-rod f, and the branch tube 1), of the mercury-t'eetling vertical tube (1, the piston r, and the piston-rod s, substantially as herein shown and described, and for the purpose set forth.
(3. In an apparatus for creating a vacuum, the con'ibination of an air pump, the tube (l, containing a column ot mercury, the piston c, the piston-rod], the tube It, containing mercury, and the piston I, with rod in, the tube 1', leading to the air-pump, and the mercury-collecting receptacle a, suspended front the pipe 1 substantially as herein shown and described, and lor the purpose set forth.
