United States Patent 3,249,974 ORNAMENTAL BUTTON Patrick J. Connolly, Medfield,- Mass., assignor to the United States of America as represented tary of the Army Filed Jan. 2, 1964, Ser. No. 335,444 8 Claims. (Cl. 24-113) by the Secreany royalty thereon. This invention relates to a button and more partlcularly to an ornamental button of the type frequently used with uniforms.

Traditionally military and military type uniforms, especially dress uniforms, have included ornamental buttons made of a base metal such as brass and usually In addition to the cost of the precious metal used in plating these buttons, the finish obtained is very diflicult to maintain in good appearance, especially where the unirosion-inducing atmospheres.

In recent years methods have been devised for treat-.

ing aluminum with an anodizing process which, with the assistance of special dyes, provides a finished article closely approximating. the appearance of a precious metalplated article. Such an anodizing process, when applied to omamenta-l buttons, results in aluminum buttons which a casual observer cannot distinguish from precious metal- However, in the process of anodizing aluminum buttons it is necessary to expose the buttons to acidic solutions which may cause non-uniform acceptance of dyes by the anodically oxidized surface on the aluminum if the acid is not thoroughly rinsed from all parts of the buttons. Thorough rinsing also prevents subsequent corrosion and formation of salts in the crevices and consequent dulling of the appearance of the buttons.

In the manufacture of -a currently preferred style of ornamental button cal-led a pierced button, problems have been encountered in attempts to take advantage of'the great economy and more lasting finish of anodized aluminum. The so-called pierced button is made of two pieces, a backplate which carries a shank used for attaching the button to the uniform and an embossed and pierced shell or front piece which bears the desired ornamental indicia and which is mounted on the backplate by rolling the peripheral portion thereof over the edge of the backplate. In the application of the anodized technique to buttons made in this manner it has been found that some of the acid required in the anodizing process becomes entrapped in the space formed between the rolled portion of the front piece and the edge of the backplate. This acid seeps out during the subsequent dyeing step and causes non-uniform dyeing of the button, which is thus unsuitable for use. Because of this problem buttons of this type are manufactured in aluminum by anodizing the two pieces prior to assembly and then, through the use of great care to preserve the finish, assembled as described above. ner have an acceptable initial appearance but the rolling of the front piece over the backplate causes numerous mlnute cracks in the anodized finish such that the button becomes very susceptible to deterioration of the finish through corrosion. In addition to this disadvantage, the separate anodizing of each of the pieces requires, in effect, twice the effort and twice the cost of the single anodizing step after assembly of the two pieces.

Buttons made in this man piece ornamental anodized aluminum button, such as It is, therefore, an object of' this invention to provide an ornamental button which can be anodized after assembly without danger of producing a non-uniform product due to acid seepage. Another object is to provide a simple means for effecting the drainage and removal of acid and rinse water during the anodizing of an assembled button of the type described without affecting the normal appearance of the button.

These and other objects are accomplished by providing means for the passage of fluids into, through and out of the space formed between the rolled portion of the front piece and the backplate such that this space may be rinsed free of acid or other material during the processing of the button.

The invention may be more clearly understood by reference to the drawings in which like numerals are used to designate like parts in all views and in which:

FIGURE 1 is a view showing the front face of a twothose applied to uniforms of US. Army personnel.

FIGURE 2 is a front view of the backplate of the button of FIGURE 1 prior'to its assembly with the front piece.

FIGURE 3 is a side elevation of the backplate of FIGURE 2.

FIGURE 4 is a sectional view of the button of FIG- URE 1 along the line 44, with a portion of thefront piece broken away.

FIGURE 5 is a sectional view of the front piece prior to assembly with the backplate.

In the illustrated embodiment of the invention, the

front piece 10 is stamped from a thin sheet of aluminum, for example, 0.02" thick. The front piece is formed, the desired indicia embossed thereon and then pierced to remove those portions of the face which do not form part of the indicia. As best seen in FIGURE 5, the front piece is formed to provide a rearwardly extending peripheral flange 11 for a purpose to be described.

A backplate 12 including a shank 13 is then stamped as a single piece from aluminum. Backplate 12 has a hole 14 in its shank which serves as a means of attaching the assembled button to a uniform. The front face 15 of the backplate is line-grooved and provided with support 1 all as best seen in FIGURE 2. These pads 16 also serve as a means of locating the front piece relative to the backplate prior to assembly. Additional locating means in the form of very small projections or pins (not shown) may be provided on the face of the backplate to register with corresponding depressions provided in the rear of the front piece.

The front edge 17 of the backplate is bevelled, while the rear surface thereof is provided with a groove or step 18, as best seen in FIGURES 3 and 4. Slots 19 passing completely through the backplate are cut in the periphery thereof and extend inwardly slightly beyond the step 18 in the rear surface thereof. The slots 19 are located in relation to the unpierced portions of the front piece so that they will be concealed from view from the front during normal use of the assembled button.

The assembly of the button is accomplished by placing thebackplate 12 into the front piece 10, aligning the two pieces by means of the support pads 16 and/or other alignment means, and then rolling the flange 11 of the front piece over the edge of the backplate in a suitable die so that the edge of the flange 11 fits into the step 18 in the rear surface of the backplate to producea substantially flat surface at the joint therebetween. The front surface of the rim 20 of the front piece may be further worked after assembly to give the desired appearance. It is important, however, both in the rolling of 3 the flange 11 over the edge of the backplate 12 during assembly and in any subsequent working of the rim 20 or edge of the assembled button to provide for and maintain a passage 21 (FIGURE 4) between the bevelled front edge 17 of the backplate and the inside surface of the rolled flange 11 of the front piece. This passage will be formed during the step of rolling the flange 11 over the edge of the backplate through the use of a suitable die. It provides a path for the free circulation of acid solution and rinse water in the space between flange 11 and rim 20 of front piece and the bevelled front edge 17 of backplate 12 during the anodizing process to follow.

Following assembly of the button, the outside surfaces of the flanged portion of the front piece are polished by means of a polishing wheel as needed to produce the desired finish. A group of the polished buttons is then placed on titanium metal racks and subjected to a degreasing and etching operation in 5% caustic soda solution at 150 F. for 5-l0 seconds. Following rinsing, the buttons are then electropolished for approximately 60 seconds, the time depending on the solution employed and the degree of electropolishing desired. The buttons are then subjected to an anodizing operation in a bath of aqueous sulfuric acid solution at 6875 F. for 30 minutes, applying a current density of about 0.1 ampere per square inch. The buttons are then thoroughly rinsed in clear water agitated by air. The thoroughly rinsed buttons are then dyed in an appropriate solution to attain the desired color. For example, the appearance of gold plating can be produced by using a mixture of Yellow G3 LW and Red B3 LW in aqueous solution, in proportions selected to match the shade desired, at pH 5-6, for approximately 30-45 seconds dyeing time. The excess dye bath is rinsed off and the dyed buttons .are then sealed by immersion in an appropriate solution such as a nickel cobalt acetate solution at 195-200 F. for 30-60 minutes, the time depending on the temperature employed. The sealed buttons are then rinsed and dried and are ready for use.

The bevelled front edge 17 of the backplate 12 insures enough clearance between the backplate and the rolled portion of the front piece to permit acid and rinse water to flow around the peripheral front edge of the backplate. The slots 19 in the periphery of the backplate permit the acid or rinse water to freely circulate into, through and out of the passage 21 so formed. The line-grooved surface 15 of the face of the backplate and the slight spacing of the embossed portions of the front piece from the face of the backplate afforded by the support pads 16 assure adequate flushing and drainage of the space between the embossed portions of the front piece and the backplate. In this manner, the acid used in anodizing the aluminum button is readily and completely removed during the rinsing step and the button is left in condition to accept the dye or dye mixture uniformly over all surfaces that will be seen when the button is applied to a garment.

The slots 19 may be varied as to both number and location on the periphery of the backplate, depending on the arrangement of the ornamental front piece. It will normally be preferable to provide at least two or three slots in order to provide good fluid circulation to assure rapid and complete flushing of the passage 21. It is desirable to have the slots located behind portions of the ornamental parts of the front piece which are physically joined to the flanged periphery thereof for purposes of concealment. It, therefore, will not always be possible, nor is it necessary, that the slots be spaced equidistantly on the periphery of the backplate or that three or any other particular number of slots be used.

While the invention has been described in terms of two-piece anodized aluminum pierced buttons, it is to be understood that it may be applied to other types of buttons. For example, where an unpierced or solid front piece is used, the slots 19 can provide for passage of fluid to and from the space between the rear face of the front piece and the front face of the backplate in addition to peripheral passage 21. The invention will be particularly advantageous in connection, with buttons which require thorough rinsing of a chemical agent from the spaces between surfaces which may be close-fitting and may become wetted by such a chemical agent at some stage in the manufacture of the buttons. It is also to be understood that the invention may be applicable to buttons made of metals other than aluminum. However, it will be especially advantageous in the manufacture of anodized aluminum buttons or in the manufacture of electroplated metallic buttons.

As a result of this invention, it is now possible to produce ornamental aluminum buttons of the type desired, anodized after assembly, which will be uniformly dyed and free of cracked edges or corroded spots or deposits of salts at the edges of crevices in said buttons. Ornamental buttons, particularly gold-simulating buttons for uniforms, will have a greatly improved appearance because of this invention. The cost of uniforms will also be reduced since the invention removes the remaining practical obstacle to the substitution of anodized aluminum buttons for gold-plated buttons in uniforms, namely the unevenness of the application of the dye or dye mixture due to bleeding of acid or other chemical agents from the close spaces between the parts of the anodized aluminumbut-tons which occurred prior to the present invention.
