ARC-LAMP.
Specification of Letters Patent.
Patented Sept. 18, 1906.
Application filed January 12, 1906. Serial No. 295,757.
To all whom it may concern:
Be it known that I, ALVIN HAUsoLD, a resident of Allegheny, in the county of Allegheny and State of Pennsylvania, have in -vented a new and useful Improvement in Arc-Lamps; and'I do hereby declarev the following to be a full, clear, and exact description thereof.
This invention relates to arc-lamps, and its object is to improve the construction of such lamps in a manner hereinafter described in order that the carbon-clutch and armature can be readilyremoved and replaced and without the necessity of disconnecting or disturbing permanent electrical connections.
The invention consists in the combination, arrangement, and construction of parts hereinafter described and claimed.
In the accompanying drawings, Figure 1 is a vertical section showing a portion of an arclamp with my invention applied thereto.
' Fig. 2 is a side view, and Fig. 3 a perspective bone of the lamp-frame.
view, on an enlarged scale, showing the clips and conductor.
My invention is applicable especially to 'a form of arc-lamp such as shown in Patent No. 777,146, granted December 13, 1904, to Lafayette E. Safford. This lamp has a central frame-tube l, which constitutes the back- Surrounding this tube is the usual magnet-coil, (not shown,) connected in the circuit in the usual way. The lower end of the tube has secured. thereto a plate 2 for positioning the lower portion of the housing 3, and has also connected thereto the cylinder 4 of the dash-pot for preventing sudden or uneven movements of the armature. The armature 5 is located inside of the frame-tube 1 and is itself tubular in order to contain the upper carbon 6, which at its upper end fits in a carbon-holder, (not shown,) which is electrically connected to the armature-tube by means of a suitable conductor. The armature at its lower end carries a piston 7, working in the dash-pot cylinder 4 for the purpose of controlling the movement of the armature. It also carries the carbonclutch 8,the specific arrangement illustrated showing this clutch carried by a plate forming a part of the piston 7 but obviously this is not necessary.
All of the parts so far described are or may be the same as shown in Patent No. 777,146, above referred to. In this lamp the current coming into the lamp from the line first passes through the magnet-coil and then4 to the frame of the lamp, from which it passes to the upper carbon and thence to the lower carbon in the usual way.
My invention has special reference to securing a better connection between the frame and the upper carbon. To this end the clutch 8 is connected to the frame by means of a suitable conductor 9, which is shown'as a spiral ribbon surrounding the lower portion of the armature 5 and connected at its upper end to the frame-tube 1 and at its lower end to the clutch-carrier, which in the arrangement shown is a supporting-disk of the piston 7 of the dash-pot. By means of this conductor the current has a direct path from the frame-tube to the carbon-clutch. It is frequently necessary in these lamps to remove the armature for inspection, and this necessitates breaking the electrical connection of the conductor 9. In order to facilitate the removal of the armature, my invention includes frictional connections between the ends of the conductor 9 and the frame-tube and clutch-carrier, or at least one of them. Each of these frictional connections consists of a suitable clip 10, which may be stamped up from sheet metal and which is soldered or otherwise electrically connected to the conductor 9 and is provided with spring-arms 11 to slide over and frictionally engage the lower end of the frame-tube l and a neck 12 formed on the clutch-carrier. These clips are made of metal having sufficient resiliency to firmly grasp the tube 1 and neck 12, so that they cannot accidentally become disengaged, but form a good electrical connection. They can nevertheless be readily disconnected when the armature is to be removed and can be just as easily again connected.
By means of the arrangement shown the armature can be removed without the necessity of disturbing or disconnecting any per- Inanent connectionswsuch as soldered joints, riveted joints, or the like-or without the necessity of manipulating binding-screws or the like which frequently become rusted so as to be diflicult of removal.
