Abstract
Abstract A multipurpose metalizing machine is disclosed, which is provided with a plurality of pressurized fluid injection ports. The machine comprises a spraying cylinder replaceably inserted into a dished holding member and adapted to be operable according to various forms of use, using ac or dc power source. Pressurized fluid injected through the plurality of injection ports allows the spraying wires to be melted by a low voltage, low current electric arc and the melted metal sprayed onto a substrate by low pressure air at relatively low velocity.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
275 words
In an apparatus for spraying molten metal onto a substrate of the type wherein two or more metallic wires are conveyed through a casing in contact with electrical conductors, said wires being brought into close proximity after passing through said casing so as to cause an electric arc therebetween to melt the metal wires, said melted metal is conveyed to the substrate by a stream of high pressure fluid, the improvements comprising: a. a spraying cylinder (1) removably affixed to the end of said casing such that said wires are brought into proximity along the approximate axis of said spraying cylinder, said spraying cylinder having a plurality of radial aperatures therethrough adjacent the end affixed to said casing, b. a hollow, generally conical wall body (2) attached to the inner surface of said spraying cylinder (1) at one end thereof, said conical wall body (2) having a plurality of aperatures (40) therethrough, the axes of said aperatures forming an acute angle with the central axis of said conical wall body (2), c. an annular injection port body (5) attached to the interior of the distal end of said spraying cylinder (1), the inner diameter of said injection port body and the outer diameter of said conical wall body defining a first injection port (18) therebetween, d. first injection means to inject a pressurized fluid through a wall of said spraying cylinder (1) into a high pressure chamber (31) defined by the inner surface of said spraying cylinder (1), said conical wall body and said annular injection port body, and e. second injection means (24) to inject a pressurized fluid interiorly of said conical wall body.

Claim 3
Dependent Claim
68 words
The metal spraying apparatus of claim 1 further comprising: an injection port tube (51) extending through said annular injection port body (5) and communicating with the high pressure chamber (31), the distal end (50) of said port tube being curved so as to direct the flow of pressurized fluid from the pressurized chamber (31) at an approximate right angle to the central axis of said spraying cylinder (1).
Claim 4
Dependent Claim
64 words
The metal spraying apparatus of claim 1 further comprising: a plurality of injection port tubes (61) extending through said annular injection port body (5) and communicating with high pressure chamber (31), the distal ends of each of said port tubes (61) being bent toward the central axis of said spraying cylinder (1), to direct pressurized fluid at an acute angle to saiD central axis.
Claim 5
Dependent Claim
47 words
The metal spraying apparatus of claim 1 wherein a plurality of spraying cylinders are coaxially mounted on said casing, said conical wall body (2), said annular injection port body (5), and said first and second injection means being located in said spraying cylinder furtherest from said casing.
