Abstract
Abstract An improved soldering device has a magazine to hold preformed solder shapes for dispensing them through a tubular duct onto a channel formed in a soldering bit. The channel leads to an opening formed in the bit to permit passage therethrough of the preformed solder shapes. An actuator is affixed to the magazine to dispense the preformed solder shapes one at a time. The preformed solder shapes do not become molten until passing through the opening in the bit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
227 words
An improved soldering device of the type for soldering by means of preformed solder shapes such as beads, the improvement comprising; a solder bit: an elongated dispenser including a magazine for said preformed solder shapes, an extractor for said preformed solder shapes arranged at the bottom of said magazine, means for actuating the extractor, and a conveying duct which opens at one end beneath said extractor and at the other end proximate the free end of said solder bit, wherein said solder bit is formed with a passageway extending entirely through said solder bit and extending transverse to the longitudinal axis of the solder bit and located proximate said free end and dimensioned to permit through passage of the preformed solder shapes and having formed therein a longitudinal groove which opens into said passageway and being of a width equal to the greatest dimension of said preformed solder shapes, wherein said conveying duct is formed in the shape of a tube with the end located proximate the passageway in said soldering bit being entirely plugged and said duct having an orifice for discharging said preformed solder shapes located proximate said plugged end and arranged above said longitudinal channel whereby upon release of a solder bead into the conveying duct the bead travels by gravity within the duct and impinges against the plug and rebounds into the orifice.
Claim 2
Dependent Claim
227 words

Claim 3
Dependent Claim
72 words
A soldering device according to claim 1, in which said extractor comprises a cylinder which is at the base of said magazine and which comprises a seat arranged to receive a predetermined quantity of preformed solder shapes and movable on its axis between an extraction position in which a predetermined quantity of preformed solder shapes occupies said seat, and a distribution position in which said quantity is delivered into said conveying duct.
Claim 4
Dependent Claim
19 words
A soldering device according to claim 2, in which said cylinder is formed with fins projecting into said magazine.
Claim 5
Dependent Claim
24 words
A soldering device according to claim 2, in which the axis of said cylinder is at right angles to that of said conveying duct.
Claim 6
Dependent Claim
68 words
A soldering device according to claim 1, in which said means for actuating said extractor comprise an angled trigger comprising a long limb and a short limb which between them have a bend hinged around a spindle mounted on the dispenser mounting, and a spiral spring coupled to said cylinder around which it is coiled and connected to the free extremity of the long limb of said trigger.
Claim 7
Dependent Claim
44 words
A soldering device according to claim 5, in which said spiral spring has one end engaged in a slot within a groove in the outer portion of said cylinder and is hooked at its other extremity on the free end of said long limb.
Claim 8
Dependent Claim
51 words
A soldering device according to claim 1, in which the end of said conveying duct situated close to the passageway in said soldering bit is plugged and said duct has a discharge orifice for preformed solder shapes situated a little before said plugged end and in alignment with the soldering bit.
Claim 9
Dependent Claim
40 words
A soldering device according to claim 1, in which said conveying duct is provided with a vent which is diametrically opposed to the said discharge orifice and which is smaller in size than that of the preformed solder shapes used.
