VACUUM-PUMP CONNECTION.
SPECIFICATION forming part of Letters Patent N 0. 447,275, dated February 24, 1891. 7 Application filed June 2, 1890. Serial No. 354,046. (No model.)
To all whom it 11mg concern:
Be it known that I, ADOLPH BERRENBERG, of Somerville, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Vacuum-Pump Connections, of which the followng, taken in connection with the accompanying drawings, is a specification.
My invention relates to a method of connecting and jacketing pipes and cooks, and is particularly adapted to be used in connection with vacuum-pumps for making incandescent lamps, the object being to render said pipes and cooks air-tight and easily connected and disconnected. This object I atmm by the mechanism shown in theacconr panying drawings, in which- Figure 1 is a Vertical longitudinal section showing a method of forming joints to connect vacuum-pipes to a fork-socket, also showing the lower end of a fork. Fig. 2 is an elevation of the same. Fig. 3 is'a vertical longitudinal section showing my device as applied to a cock. Fig. 4 is an elevation of the same.
In the drawings, A and A represent the pipe that leads from a vacuum-pump to the lamps to be exhausted.
E and E are jacketing-pipes made so much larger than the vacuum-pipe as to leave a space S between the two, as shown. This space S may be filled with oil or some of the fluid adapted for the purpose of sealing oints, &c., or the space may be a vacuum in connection with an auxiliary pump.
C C C represent a jaoketing-case connected to the pipes E and E by the following described device:
E is a thimble having an external screwthread cut on each end, as shown. The ends of this thimble E are internally coned, so that the packing K and K may be forced partly into themthat is, between the ends of the thimble and the pipe E on the one side and the part C of the jacketing-case on the other.
F and F are screw-collars adapted to engage with the screw-thread on the ends of the thimble E and coned interiorly, so as to embrace the packings K and K.
As the several joints shown in the drawings are all like the one just described, they need not be explained.
The jacketing-case C has a bottom C screwed into it, as shown, and at the top has an annular member C projecting from its interior wall. This annular member serves as a buttress for supporting the socket-piece B, said socket-piece beingheld firmly in place by the screw-follower B. The upper open end of the jacketing-case is cupped for holding any suitable sealing-fluid.
In Figs. 1 and 2 I have shown in connection with my device the socket end P of a fork, such as are made by glass-blowers for connecting the bulbs of incandescent lamps to the vacuum-pump, and fits by a groundjoint E into the socket-piece B. A similar device may be used for connecting the vacuum-socket B to any article to be exhausted.
In case this device is to be used for a part of a stop-cock, then a key D, Figs. 3 and 4, is to be used. This key D has a handle H and a transverse opening D for the purpose of connecting the passage in the vacuumpipes A and A when desired. A small opening d is made in the key D, extending from the transverse opening D to the lower end of the key. This opening d allows the otherwise imprisoned air or liquid below the end of the key to escape, otherwise it is found.
difficult to make the key stay in place.
Having thus fully described my device, what Iconsider as new, and wish to secure by Letters Patent, is'
In connection with a system of vacu umpipes, the combination of a socket piece adapted to receive a key or the socket end of a fork, and having passage-connections with the vacuum system, with the jacketingpiece 0, having passage-connection with a jacket-ing system as described, substantially as and for the purpose set forth.
ADOLPH BERRENBERG.
