(GRANTED UNDER THE PROVSIONS OF THE ACT 0F MARCH 3, 1921, 41 STAT. L., 1313.)

To ZZ cli/10m t'ymcty concern:

Be it known that I, ALFRED GAnRinL Quim', engineer, citizen of the French Republic, residing at Neuilly-sur-Seina Department of Seine, France, have invented certain new and useful Improvements in Soldering Irons, (for which I have led applications in lFrance, Jan. 21, 1914, Patent No. 475,124; Germany, July 10,1920; Great Britain, July 12, 1920, and Italy, .Tune 17, 1920,) of which the following isa specification.

The object of the present invention is a soldering iron provided with means for adjusting the same at various angles relatively vto a handle and supporting stern and represented by way of example in the accompanying drawings. y

Fig. 1 a vertical section of the soldering iron in its normal position.

Fig. 2 represents, in a section, one of the positions the bit ot the iron can occupy with respect to the handle.

Fig. 3 is a side view ot a second position of the bit of the iron.

Fig. 4 is a partial vertical section along P1-A in Fig. 1.

Fig. 5 is a horizontal section along B--B of Fig. 1.

The soldering iron forming the object of this invention consists essentially of a copper bit 1 the point 2 of which may be of any suitable form, whilst the rear part or heel has a blunted or cut side 3. and a mortise 4. This mortise can be lined on the inside with a sheet of nickel or other suitable material formed from a single piece so as to cover the walls ot the mortise and folded or bent down on the outer sides of the rear part or heel of the copper bit.

The bit of the iron is Xed to a handle consisting of a central stem 6 terminating at the top with an eye 7 engaging in the mortise 4 and united with the bit by aI pin 8 running through the two sides of the mortise 4 and the eye. This stem 6 is {itted inside a socket 9 the top part 10 of which is slightly enlarged or bulged formed with a fiat supporting surface. The socket 9 penetrates to a certain extent into the wooden handle 11 of the iron and is secured therein by a binding screw 12 running through the ferrule 13, the handle 11 and a metal tube 14 inside the wooden handle 11. There is a transversal pin 15 in a suitable part of the stem 6. This pin can work in elongated mortises 16 made in the extremity oi the socket 9 which is lodged inside the wooden handle. This stem runs through the wooden handle and terminates at the lower extremity of this handle in a threaded part 17, on which a winged nut 18 resting on a washer 19 can be screwed. There is a spiral spring 20 insidethe handle in the metal tube 14, the said spring bearing by one of its ends against the lower end of the socket 9 and by its other end against the washer 19.

It can easily be seen Fig. 1, that when the winged nut 18 is tightened, the iron is firmly maintained in the position represented in thisfigure owing to the tensile stress exerted by the nut on the stem 6, a stress which causes the bit of the iron to bear iirmly against the upper flat supporting surface of the top part 10 of the socket 9.

To bring the bit from the position given in Fig. 1 to the position given in Fig. 2, it suffices after having loosened the nut 18 by a few turns to push back the stem 6 pressing on the threaded end 17 so as to bring pressure to bear on spring 20 and raise pin 15 in mortises 16; the bit by this means being free to move relatively to the flat top of the sur- 'face or seat ot' the upper part 10 of the handle 9 and permit the pin 8 to freely oscillate or` pivot in the eye 7. 1t suffices to give the iron a certain incline downwards or rest the bit against some object to bring the said bit to the position represented in Fig. 2. lVhen the change is made by pressing the bit against some object there is no need to press on the stem 6 to compress the spring, it sufiices to loosen the nut 18. As soon as pressure is removed trom the end of the stem6, the spring 20 pulls the stem back and keeps the bit in the position to which it has been adjusted the nut 18 may then be readilyl tightened to iiX the bit in its new position. A similar operation brings the bit to the posi tion shown by Fig. 3.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is:

1. A soldering iron of the class specied, comprising a stem, a tubular socket in which the stem is reciprocatingly mounted, a handle attached to the socket, and a bit pivotally connected to the one end of the stem and having varying angular surfaces at the heel portion adjacent to the point of pivotal connection thereof to the stem to effect angular adjustment of the bit with rela-- tion to the end of the socket and means for sustaining the bit in its adjusted position.

2. A soldering iron of the class specified, comprising a supporting means with a flat end, a stem reciprocatingl'y mounted in the supportingmeans, a bithaving a heel pivoted to the one end of the stem and movable in close relation to and adapted to be held fixed against the fiat end of the supporting means, the heel of the bit being provided With bearing surfaces at angles toI each other to positively engage the flat end of the supporting means, and means for releasing the bit for adjustment and for fixing the bit inl its Yadjusted position.

3. A soldering iron of the class specified, comprising a supporting means consisting of a handle with a tubular socket projecting therefrom, a stem reciprocatingly mounted in the socket and provided with a screwthreaded extremity extending beyond the rear end of the handle, adjusting means engaging the screw-threaded end of the stem, a spring surrounding the stem in the handle and operating to retract the latter, the tubuifiieoe lar socket having va flat end, and a bit provided with a mortise into Which the stern projects for pivotal connection to the heel of the bit, the heel of the bit being formed with bea-ring surfaces at different angles to engage the flat end of the socket.

41. A soldering iron comprising a tubular handle, a tubular socket secured thereto and provided with a slot therein, a stem reciprocatingly mounted in the handle and socket and having a pin engaging the slot of the socket, means engaging the one end of the stem adjacent to the handle for fixing said stein against movement, the stem also projecting beyond the free end of the socket, and a soldering bit having a. slotted heel to receive the projecting end of the stem for pivotal connection to the latter, t-he'heel. of the bit having angular surfaces to positively engage and be held against the adjacent end of the socket to dispose the bit at varying angles relatively to the socket.

ln testimonj7 whereof l have hereunto set my hand in presence of tivo subscribing Witnesses.
