WILLIE W. FARNSWORTH, OF BRUSI-ITON, NEW YORK.
To all whom 'it may concern:
Be it known that I, VILLIE WV. FARNs- WORTH, a citizen of the United States, and a resident of Brushton, in the county of Franklin and State of New York, have made certain new and useful Improvements in Soldering Apparatus, of which the following is a specification.
My invention relates to improvements in devices for soldering parts, especially parts of jewelry, optical goods, etc., and it consists in the combinations, constructions and arrangements herein described and claimed.
An object of my invention is to provide a device by means of which two small `parts.
may be held rigidly, while the soldering operation is conducted.
A further `object of my invention is to provide a small pad of heat insulating material, which may be held in the hand while the parts to be soldered may be securely held upon the pad by devices which may be easily manipulated to release or retain the parts to be mended.
A further object of my invention is to provide a pad having supporting devices capable of holding` the interchangeable tools, such as tweezers or clamps, the supporting devices being` of such a nature thatI the tools may be held in various positions.
Other objects and advantages will appear in the following specification and the novel features of the device will be particularly pointed out in the appended claims.
MyV invention is illustrated in the accompanying drawings forming part of this application in which- Figure 1 is a plan view of the device showing the parts in their operative position, Fig. 2 is a section along the line 2 2 of Fig. 1, Fig. 3 is a perspective view of a pair of tweezers for use with the pad, and` Fig. 4 is a perspective view of another form of holding tool, which may be advanta geously employed.
In carrying out my invention I provide a base 1 preferably of wood or other heat insulating material, upon which I ino-unt a pad 2 of non-combustible material, such as asbestos. In order to retain the pad upon the base 1, I provide a metal band or rim 3, which extends around the base, and is secured to it by means of brads 4. The pad 2 is cut to t just inside of this rim 3, and both the pad and the base are provided with Specification of Letters Patent.

registering openings through which pass copper rods, such as those shown at 5, 6, 7 and 8. The bottoms of these rods are threaded, as shown at 5a, 6a, TfL and 8a to receive thumb nuts 5", 6b, 7b and S". The rods 5 and 8 are longer than the rods 6 and 7 and are designed to receive adjustable heads 9 and 10, respectively. In the present instance, I have shown these heads as brass cylinders provided with openings to permit the passage of the rods 5 and 8 and having set screws 9? and 10a, respectively, to clamp theheads vin position. The heads 9 and 10 are also provided with openings 11 and 12 respectively. A set screw 11a is arranged to'pass into the opening 11 and a set screw 12a is arranged to pass into the opening 12. A brass spring 13 is disposed between the head 9 and the pad 2 so as to press the head 9 and rod 5 upwardly. A similar spring 14 keeps the head 10 and rod 8 in an upper position.
Secured to the upper ends of the rods 6 and 7 are the retaining devices 15 and 16 respectively. Obviously they may he of other shapes than that shown in the drawing. The heads 9 and 10 and the retaining devices 15 and 16 are preferably made of brass.
In Figs. 3 and 4, I have shown the tools which are designed to cooperate with the heads 9 and 10 in holding the work firmly upon the pad. Thus in Fig. 3 a copper rod 17 is shown. This rod is designed to pass through either of the openings 11 or l2 and to be retained therein in adjustable posit-ions by means of the set screws 11a and 12a. The outer end of the rod 17 is provided with a loop 17a, which is designed to receive a pair of tweezers 18. These tweezers consist merely of a pair of arms joined together by an integral loop. Since the arms are thicker at their ends than at the point where they are united to the loop, it will be apparent that the nearer the ends of the arms are to the loop 17a, the closer together the arms will be forced so that when the arms are placed over the part to be mended and the ends of the arms are pushed toward the loop 17a, they will firmly clamp the' article. In Fig. 4 I have shown a similar rod 17h which is provided with a downwardly curved portion 17 c having serrations at its end to prevent the slipping of a part which it is designed to retain.
From the foregoing description of the various parts of the device, the operation thereof may be readily understood.
Let us suppose it is desired to solder together a frame of a pair of nose glasses which have been broken. In Fig. 1, I have shown the nose glasses in position to be soldered. In order to hold the parts t0- 'gether, I have used two sets of tools, such as shown in Fig. 3. One of these parts X is first inserted in the tweezers 18, which are adjusted to clamp it securely, as already explained, and the rod 17 is then placed in the head 9 which is then rotated on the rod 5, the rod being pushed through the opening 11 until the piece to be held is' in the proper position upon the pad. The set screws 9a and 11a are then tightened, and the thumb nut 5b is then screwed up, so as to hold the piece securely upon the pad. A similar tool is then placed in the head 10 and adjusted to hold the other part Y of the article to be mended. The retaining devices 16 and 17 are then swung over those portions of the article which rest upon the pad and the thumb nuts 6b and 7b are tightened to provide additional holding members. It will be of course understood that the joint between the parts is first arranged in the position in which it is to be soldered.
The soldering operat-ion may then be proceeded with while the pad is held in the hand and the pad may be turned without any danger of the parts becoming loosened or moving from their relative positions. When the operat-ion is over, it is only necessary to unloosen the thumb nuts 5b, 6", 7b and 8b and tweezers 18 when the article can be immediately removed.
' It will be seen that I have provided a pad, which is extremely light, but which will firmly retain the parts in position during the soldering operation. The rods 5, 6, 7
other reason it is desired to change the pad, all that it is necessary to do is to remove the thumb nuts, pull out the rods, bore holes in another' pad and place the new pad in position. Obviously other tools of other shapes than those shown might be used with the rotatable heads 9 and 10, without departing in the least from the spirit and the scope of the invention.
I claim 1. A soldering apparatus comprising a noneonducting ba se of light material having perforations, a metallic rim secured to the edges of said base and arranged to project upwardly therefrom, a pad of heat-insulating material disposed within the rim upon said base and being provided with openings arranged to register with those in the base, a series of rods arranged to extend through said openings, said rods being threaded at one end, a series of thumb nuts for said rods, heads provided with openings disposed on certain of said rods, each head being rotatably and longitudinally adjustable with respect to its rod, springs for normally holding said heads in position, and interchangeable clamping tools having portions arranged to enter openings in said heads and to be adjustably retained therein.
2. In a soldering apparatus, a nonconducting base, a rim therefor, an insulating pad disposed upon said base within said rim,
said base and said pad being provided with registering openings, a series of rods disposed in said openings, the lower ends of said rods being threaded to receive thumb nuts, and clamping devices carried by the upper ends of said rods, said rods being arranged to be moved longitudinally by means of the thumb nuts and said clamping devices being arranged to rotate with said rods to permit their adjustment into various po- :sitions with respect to the pad.
and 8 are made of copper, as are also the tools 17 and 18. Acids may be used with these tools which would corrode iron, but which will not corrode the copper parts. l When the pad 2 becomes Worn, or if for any WILLIE w. FARNswoRTH.
