PETER FRED ALZMANN, OF BEOOKLYN, NEW YORK.
ELECTRIC BRAZING-SWITCH.
Specification of Letters Patent.
Patented May e, 1919.
Application filed September 24, 1917. Serial No. 193,014.
T 0 all 'whom z't may concern Be it known that I, PETER FRED ALZMANN,
a citizen of the United States of America,
and a resident of the borough of Brooklyn of the city of New York, county of Kings, and State of New York, have invented a certain new and useful Electric Brazing- Switch, of which the following is a specification, the same being a full, clear, and eX- act description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to neans for joining or binding together metal surfaces or jonts by the use of a metal alloy fused under a suitable degree of heat, whereby the metal alloy, partly by Chemical action and partly by cohesive force, joins or binds the said metal sui-faces or joints together.
The invention appertains particularly to devices by means of which metal articles may be quickly and Conveniently brazed together by the use of an electric current controlled by a switch such as a knife blade switch or other suitable switching mechanism, the term brazed being employed-to include soldering or analogous Operations.
In the-drawing which accompanies and forms a part of this specification Figure 1 represents a plan View of an instrument 'constructed according to my invention; Fig. 2 is a side elevation thereof; and F ig. 3 is a View in section taken on the line 3-3Fig. 1. i Iu the drawing the numerals 1 and 2 denote the terminals of the device. Upon a suitable base, which preferably consists of a suitable dielectric material, is mounted a circuit controller 3 which is indicated in the drawing and shown inthe conventional manner and which comprises a knife blade switch which may be located at any desired position in the Construction of the apparatus or at any desired point Where it may be conveniently reached'by the operator.
The switch 3 is mountedon the parts 3' and l" and the element comprising the arm 4 is connected with the part 3' in a movable relation at 4'. The said element 4: is also connected in a movable relation with the guides 8, 8" and the rod 7 respectively at 8', and the lever 6 is movably connected With the rod 7 at 6'. By the manipulation of the lever 6 the guides 8, S and rod 7 are moved horizontally either to the right or left, movement in a transverse direction being lim t d by the. inclosing strap 14,.
A clamping j aw 9 and relatively movable jaw 13 are carried by the stationary arm 5, the jaw 13 being caused to approach or recede from the j aw 9 by the manipulation of a screw 10 nounted at 12. A clamping jaw 9' is carried, andguided in its movement toward and away from the jaw 9, by the guide 8. A relatively movable jaw 13' is caused to approach or recede from the jaw 9' by a screw 10' which is mounted at 12' on the guide 8 which serves to guide and regulate the position of the same.
hen the lever 6 is in a median position the parts 12' and 12 will be the same distance apart as the parts 13', 13, as indicated in the drawings. If the lever 6 ismoved to the right hand the parts 12' and 12 will be farther apart than the parts 13', 13 owing to the movement of the arm 4 on its pivot 4:', while if the said lever G is pushed in the .opposite direction, the parts 12 and 12 will be nearer together than the parts l3',`13, the jaws 13', 9 being thus noved differentially toward and away from the jaws 9, 13, whereby a Variable pressure in the same horizontal plane may be applied to the pivotally nounted 'jaws and the work to be brazed may be held at diflerent angles if desired.
hen the lever G is in a median plane, however, as shown, the parts to be brazed, as metal pieces 11 and preferably interposed alloy 12", may be held in alinement so as to extend in one straight line.
hen the parts are positioned, and the conditions are such as above described, the,
electric current, which may be derived from any suitable source of supply, will be inoperative so long as the knife blade is open or elevated, the part 'of the circuit which extends from the terminal 2 to the blade of the switch (through arm 5, metal pieces 11, 11' alloy 12", jaws 9 and 9', guide 8, and arm 4) being insulated from the part of the circuit conprising the switch Contacts or conductors (adapted to become engaged with the knife blade upon the closing or lowering of the latter) which are electrically connected with the terminal 1.
Upon the closing of the switch 3, however, the electric current will be passed through the work at the point of clamping` by which operation the two pieces 11, 11' become brazed into au integral mass, the novable current supplying electrode having served to establish an electric circuit, under pressure, between the work to be brazed an the alloy to be melted.
It will be seen that my apparatus 'may be 'quickly and Conveniently controlled electrically under the various conditions of opera: tion, and that other forms "of electrodes and means'for actuating the same may be substituted for the ones described and shown,
I and also that the relatio n between the time &G
of the application of the pr'essure and the time of the application of the ,current may follow the common presentor 'any suitable practice.
I Wish itto be understood that I do not' desire to be limited to the particular use or ethe exact details of Construction shown and "described, for obvious modifications will v to b e applied to the work, the said clamping devce comprising relatively fixed and movable jaws and also a screw to force the movable jaw'toward and away from the fixed one, a stationary support .to hold a'similar relatively 'movable pair of'jaws and clamp-. 'ing means, and a manually actuated means to operate the' slidable bodies in order to move the first named pair of jaws differentially toward and away from the other pair horizontal plane to the work between the two sets of jaws in the line of the pressire applied to the work.
In testimony of the foregoing specifica tion I do hereby sign the same in the borough of Brooklyn of the city of New York in the county of Kings and State ofi New York this 7th`day of September, 1917.
