TENSIQN DEVICE.
Specification of Letters Patent. o Patented Dec, 10, 1912..
Application filed Morph 23, 1911. Serial No. 616,473.
To all whom it may concern:
Be it known that l, HARRY l). MADDEN, a citizen of the United States, and a resident of Bloomfield, in the county of Essex and {5, State of New Jersey, have invented a new and. useful Improvement in Tension Devices,
of which the following is a specification.
My invention relates to devices for applying tension to filaments, threads, iibers and 353 similar structures as they are drawn from coils or reels and applied to mountings or are otherw se used, and it has for its ob ect to provide a device of this character which shall be particularly adapted for use in connection with extremely fragile materials,
2t? accuracy.
The filaments of electric incandescent lamps are sometimes applied to mountings therefor by a suitable back and forth manipulation of the mountings, during which operation it is highly desirable that the filament be maintained taut. ()wing to the fragile nature offthe filament material used in some lamps, it is necessary that the means :for exerting tension upon it in order 8% to maintain it taut shall be of an exceedingly delicate character,while being sufiiciently rigid and durable to be free from undue wear and attention. while in use.
The device of the present invention permite of applying anysuitable degree of tension to materials of extreme fineness and fragility without causing breakage thereof, and without being subject to wear or requiring increased attention with continued use. ln the single figure of the accompanying drawing, which is a view partially in section and partly in elevation of a device embodying my invention, a filament 1, which may be composed of tungsten, molybdenum or any hother ,desired material, is drawn downwardly from any suitable source of supply, such as a coil or reel (not shown) by a back-and-forth movement or other proper manipulation of a mounting 2 to which it is thereby applied. The mounting 2 is carried at the inner end of a manually adjustable'holder 3 that projects through one side of a bell-jar 4, within which the manipula tion ofth'e filament is efiected and to which 55 a suitable neutral gas is preferably admitted through a supply pipe or hose 5 when the filament is composed or tungsten or molybbe oxidized it highly heated in air. The holder 3 is surrounded, where it passes through the bell-jar 4, by a rubber or other suitable pliable bushing 6 that permits of movement of the holder in any direction for the purpose of effecting the proper movements andinanipulations of the mounting 2.
it is led through a tube 7, t-he upper end of which has an internal diameter somewhat larger than the filament, and the lower end of which is provided with .achamber or enand containing;- a tube 10 that is sealed to its lower end and extends nearly across the said inner tube being materially larger than the filament. The exit end of the tube 7 is for directing and limiting'the movements of the filament. The inlet stem 9 is connected to a hose or pipe 11 that leads from a suit-' able source (not shown) of supply of comconnection between the said parts for the purpose of regulating-the degree of force with which the compressed air enters the enlargement 8.
both upwardly and downwardly around the filament'and out of the chamber provided by the enlargement, and,- by reason of its friction upon the filament, subjects the latter to tension. By reason of the smaller-internal diameter and greater length of the tube 7 above the enlargement, the friction upon the filament in the said upper portion is greater than that upon it in the lower portion, the resultant effect being a force tending to draw the filament upwardly in opposition to the "tension mechanically applied to it as it is Wound upon the mounting 2.- The tube 10 within the enlargement 8 serves to prevent the drafts of air enteringthe enlargement through the inlet stem 9 from blowing directly against the filament and the enlargement 8 is of such size that the pressure therein may become distributed and equalized.
During the application of the filament to the mounting 2, it is preferably heated to a suificient degree to render it quite pliable denuni", or any other material which would As the filament l is drawn downwardly,
interior thereof, the internal diameter of- Air that enters the enlargement '8 passes largement 8 having. a lateral inlet stem 9 reduced to a proper diameter to ailord means pressed air, a valve 12 being included in theby the passage of an electric current through it, and, to this end, the holder 3 constitutes one terminal of n electrical circuit'including any suitable source, such as a battery 13. An apertured terminal device 14, having mercury extending across the aperture, is connected to ,the other terminal of the source and is mounted over'the opening in the upper end of the bell jar 4, the mercury serving to make electrical contact with the filament where it passes through the aperture. lVhen the mounting 2 is placed upon the holder 3, the leading-in wires make engagement therewith, and, when the filament is connected to either or bothof the' said wires, the circuit is completed. The electrical circuit also preferably includes a magnet "or other similar device 15 constituting a part of an electro-magnetically operated brake 16 that is released during continuity of the circuit, but is set so as to, prevent move- .ment of the filament when the circuit is interrupted. The brake is provided for the purpose of preventing the filament from being blown out of the upper end of the tube 7 when it is broken during its application to the mounting, or when it is desired to substitute a new mounting for one to which a filament has been applied. I
Other suitable means may be provided, if desired, for stopping'movement of the filament upon interruption of the electrical circuit, that shown being only indicative of suitable means for the purpose. It may be desirable, for instance, to. stop the flow of air into the enlargement 8 of the tension demeans for regulating the force of the dr ft recting a draft upon the filament in 'oppo-= vice upon interruption of ing the filament.
