FILAMENT TUBE.
Application filed April 5, 1926. Serial No. 99,784.
This invention relates. to filament tubes employing a filament contained in a vacuum tube and used for heating, lighting or other purposesyand the object of the invention is to provide improved means for coupling such tubes or the circuit Wires leading to the filament thereof with a source of electric supply whereby the attachment and detachment of a tube may be accomplished in a quick and efiicient manner thus effecting a material saving in time and labor in the attachment and detachment of tubes of the class under consideration; a further object being to provide the socket end ortion of the tube with a socket composed o insulating material and containing one or more apertures in which one or more contacts are mounted whereby a plug inserted into the aperture or apertures in the socket of the tube, will engage one or both of said contacts; a still further object being to provide means for interlocking the tube with the fixture in connection with which the same is coupled to prevent accidental displacement thereof; and with these and other objects in view, the invention consists in a tube of the class and for the purpose'specified, which is simple in construction, efficient in use, and which is constructed as hereinafter described and claimed- The invention is fully disclosed in the following specification, of Which the accompanying drawin forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which: A
Fig. 1 is a side, and sectional view of a tube made according to my invention and illustrating a fixture socket or member in connection with which the same is mounted.
Fig. 2 is a section on the line 22 of Fig. 1.
F ig. 3 is a section on the line 3-3 of Fig. 1.
Fig. 4 is a view similar to Fig. 1 but showing only a part of the construction with parts detached and showing a modification; and,
Figs. 5 and 6 are sections on the lines 55 and 66 of Figure 4 of the drawing. I
In Fig. 1 of the drawin I have indicated at 10 a filament tube 0 the incandescent type, and at 111 have represented the filament within the tube and at 12 and 13, the circuit wires leading from the filament to the socket 14 at the end of the tube. The socket 14 is composed of-any suitable insu- -lating material, and in the construction sho'wn in Figsyl to 3 inclusive, the socket is provided with two apertures 15 in which are mounted terminals or contacts 16 and 17, the contact 16 being in circuit with the Wire 12, while the contact 17 is in circuit with the wire 13 as clearly seen in Fig. 1 of the drawing The filament tube and its several parts are fixedly retained to the socket 14 and the contacts 16 and 17 by any suitable means, such for example as a filler and'binder 18 indicated in Fig. 1 of the drawing.
It Will'be understood that the socket 14 is substituted for the usual screw or threaded end provided on tubes of the common form and construction, and the object of my invention is to provide a tube construction which will permit of the quick attachment and detachment of the tube with a fixture socket or member 19. The member shown is of special construction and ismade the subject matter of a companion application, but is shown and described herein to clearly illustrate the use of my improved tube.
The member 19 will take the place of the usual socket employed for the mounting of 30 tubes havin threaded ends and may constitute a soc et member or part of a fixture of any kind or class. In the construction shown, the member 19 comprises a body of insulating material having a small bore'20 at 5 one end through which the circuit wires 21 and 22 are passed into a large bore 23 at the other end of the member 19. The bore 23 is adapted to receive the socket 14 of the filament tube 10, said socket fitting snugly therein but free to move inwardly and outwardly therethrou h, as will be apparent. Supported Within the bore 23 or at the base of said bore are two terminals 24 and 25 with which the wires'21 and 22 are coupled re 1 spectively, the terminals being held in place by screws 26 or in any other desired manner. These terminals are adapted to engage the contacts 16 and 17 of the socket 14 as clearly seen in Fig. 1 of the drawing, any suitable p means being employed for frictionally or tensionally locking the contacts 1617 with.
. large bore 23 at one end of the member 19 be apparent.
forms a skirt portion 28 which protects the terminals 24: and 25 and prevents the closing of the circuit between said terminals by accidental engagement with any metallic body that may strike the member, 19.
In Figs. 4; to 6 inclusive, I have shown a modified form of construction wherein a filament tube 10 is provided with a socket end 14 provided with a single aperture'15 instead of two apertures 15 as seen in Figs 1 of the drawing, the aperture 15 being positioned centrally of the socket 14 and the circuit wires 12 and 13 with the filament of the tube 10 are coupled with contacts 16 and 17 positioned within the aperture 15 in spaced relation. Withthis form of construction a fixture socket or member 19 is employed, provided with a single terminal member having two terminals 24* and 25 insulated from each other as seen at 29,
the terminal 24 being adapted to engage the contact 16 while the contact l'i" engages a groove 30 in the terminal 25 Circuit wires from a source of electric supply 21 and 22 are coupled respectively with the terminals 2 1 and 25 The general form of the member 19 is the same as the member 19 shown in Fig. 1 of the drawing, except that the skirt portion 28 is provided with a bayonet slot 31 to receive a projecting pin 32 mounted in the socket 14 of the tube 1O whereby the tube 10 may lock in engagement with the member 19 to insure against accidental displacement of the tube, as will Of course, any suitable means may be employed for this purpose. It will also be understood that the tensional and frictional engagement of the contacts 1617 with the terminals 24J"25 will be sufficient to accomplish this result.
It will be understood that my invention is not necessarily limited to any form and construction of the socket 14t-1i nor to the manner of securing the socket in connection with the contact proper nor the form v and construction of the aperture or apertures formed in such socket, nor am I necessarily limited to the specific type of fixture socket or member 1919 and various other changes in and modifications of the construction herein shown and described may be made within the scope of the appended claim without departing from the spirit of my invention or sacrificing its advantages. v
Having fully described my invention, what I claim as new and desire to secure by Let ters Patent, is
A filament tube provided with a base having apertures, resilient terminals mounted entirely within said apertures and connected to the filament of the tube, and means for retaining said base in connection with a plug adapted to be coupled therewith.
In testimony that I claim the foregoing as my invention I have signed my name this f 26th day of March, 1926.
MARK HARRIS.
