Description
A. B. NELSON ELECTRICAL soLDEHING IRON Filed Feb. 5, 1922 @Hou/ww ?atentecl Oct. 21, 1924.
ARTHUR BERNARD NELSON, OF ABERDEEN, SOUTH DAKOTA;
ELECTRICAL SOLDEBING IRON.
Application filed February 3, 1922. Serial No. 533,914.
To all whom imag/concern:
Be it lmown that I, ARTHUR BERNARD NELSON, a citizen ofthe United States, residin at Aberdeen, in the county of Brown l and tats of South Dakota, have invented new and useful Improvements in Electrical Soldering Irons, of which the following is a specification.
rIhis invention relates to an electric so-ll dering iron, and the object is to provide a quick heating device, with no exposed flame or arc, which maybe used where certain other type cannot be employed.
In the drawings, Figure 1 isa view of l5 the device in elevation, and Figure 2 is a view in longitudinal section.
A further object is to provide a device which may readily be kept clean, no carbon dust reaching the outer surface of the tip,
l0 and also to provide a convenient and durable tool which only requires the occasional renewal of the carbon electrode.
A still further object is to provide particular means for mounting the carbon elec- 55 trode and particular controlling means, es-
pecially adapted for the purpose intended.
With the foregoing and otherobjects in View, the invention consists in the novel construction and arran ement of elements de- D scribed and claime it being understood that modifications may be made within the scope of the claims, Without departing from the spirit of invention.
The handle may be of Wood, and is 5 provided with a central longitudinal bore, and with a longitudinal slot 11. Mounted alongside of this slot and on the outer surface of the handle is a slotted plate 12 secured by means of screws, 13 and 14.
l A brass tube 15 is mounted Within one end of the bore of the handle, and is secured by means of a set screw 16 engaging a nut'17 carried by tube 15.
An iron rod 18 has one end thereof eni closed by a, short section of bre tube 19 acting as a bearing. This 'tube or sleeve has connection with a lead Wire 20, and a conductor 21 has connection with a copper tube 22 slidably engaging rod 18' at the point l 23,' Where electrical contact is made.
A socket 24 of spring steel is rigidly carried by one end of rod 18, and receives the carbon electrode 25, the latter being readily renewable by releasing set .ff-crew 16 and 'withdrawing the elementI 18 from the end of handle 10.
The copper tip 27 includes a bore 28 and is provided with an outwardly extending flange 29, the latter being engaged by the flange 30 of bushing 31. This bushing has threaded engagement with bushing 33 rigid with reference to tube 15.
The porcelain sleeve 35 surrounds and insulates the carbon electrode, being mounted as shown. Between the tip 27 and the brass tube 15, an insulating washer 36 is located, and serves an obvious purpose.
In order to control the position of the carbon electrode with reference to the copper tip 27 I provide an operating device including an insulating member, or knob 39 mounted on a stem 40, the lower end of which is connected with rod 23 and therefore serves to shift the rod longitudinally and also the carbon electrode mounted in socket 24. When element 39 is moved forward by the pressure of the thumb or finger, this spring is compressed, and the, carbon electrode is brought into contact with tip 27. When pressure on arm' 39 is released, the spring expands and normally separates elements 25 and 27. v
It will be observed that the circuit is through bar 18, socket 24, carbon electrode 25, tip 27, the bushings connecting the tip with the lbrass tube 15, and then through contact 23 and conductors 22 and 21.
Having thus described the invention, I claim:
1. In an electric soldering iron, a soldering tip, a slidably mounted bar, a socket carried by the bar and electrode mounted in the. socket and projecting into the tip, insulating means interposed between the bar and tip, conductors connected with the bar and tip, and resilient means normally rertaining the bar and tip separated.
2. In an electric soldering iron, a soldering` tip, a tubular member, a slidably mounted bar within the tubular member, an
electrode carried by thebar and projecting into the tip, and means for effecting elec-w` trical and mechanical connection between the tip and the tubular member, said mechanical and electrical connecting ,'means 105 comprising a plurality of bushings adjustably connected with each other. 3. In an electric soldering iron, a handle,
CFI
the tip, resilient means normally holding the electrode and tip separated, and a. manually l0 operated device connected with the bar, for moving the bar, socket, lnd electrode toward thev tip.'
ln testimony whereof I ax my signature.
ARTHUR BERNARD NELSON.
