APPARATUS FOR ORNAMENTING SOFT-METAL HOLLOW WARE.

SPECIFICATION forming part of Letters Patent No. 568,839, dated October 6, 1896. Application filed January 13,1896. Serial No. 575,374. (No model.)

low Ware Composed of Britannia and other- Soft Metals, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in which Figure 1 is a side elevation of a piece of hollow ware having ornamental fluting produced by my improved apparatus. Fig. 2 is a side elevation of my improved apparatus for flutin g hollow ware. Fig. 3 is an enlarged vertical section of the upper portion of the apparatus. Fig. 4 is a horizontal section on the line 4 4 of Fig. 2. Fig. 5 is an edge view of the fluting-die.

To produce the style of ornamentation known as fluting in hollow ware, such as pitchers, bowls, vases, &c., composed of britannia and other soft metals, it has usually been customary to fill the vessel with pitch to provide the desired yielding resistance and then indent or drive in the exterior surface 4 along the line of the design with a blunt and smooth edged tool held in the hand and struck with a mallet or hammer, the tool being moved after each blow to follow the design of the fluting. After the completion of the fluting by making the necessary indentations at suitable distances apart entirely around the vessel the pitch is melted out and the article is then plated and finished. This method of fluting is slow and expensive, and when the article is to be afterward burnished the operation must be performed by hand, as the indentations will not permit the use of a lathe for this purpose.

My invention has for its object to greatly facilitate the operation of fluting soft metal vessels and to enable the work to be done after the article has been plated and burnished and to this end my invention consists in a novel apparatus for producing flutin g on soft-metal hollow ware, as is hereinafter fully described, and specifically claimed.

In carrying my invention into effect I provide an apparatus consisting of a bed A, supported on legs a and provided with a vertically-adjustable table I) for supporting the article to be fluted. At one end of the bed A is an upright 0, against which is placed a removable concave rest or form B, preferably composed of Wood or other suitable material and shaped to nicely fit the pitcher, bowl, or other article of soft-metal hollow ware to be fluted, the said concave rest preferably extending half-way around the article, as shown in Figs. 2 and.4, forming, as it were, a counterpart half section of the same, whereby it is properly supported or backed when held against said rest. From the back of the rest B projects a screw 10, which passes through a hole in the upright c and is provided outside the same with a thumb-nut 12, whereby the rest can be clamped securely in place.

A closely-fitting plug C, of wood or other suitable material, which may be composed of a single piece or made in sections, as shown in Fig. 3, is preferably first placed within the neck or mouth of the article D of hollow ware to be fluted, whereby any change in the shape of the neck or upper portion of the article is prevented while being operated upon by the die to produce the fluting, as hereinafter described. The article so plugged is then placed against the concave rest B, as shown in Figs. 2, 3, and 4, ready to be acted upon by the fluting-die f. This die is composed of a piece of sheet-brass or other hard metal having a smooth rounded edge conforming to the line of the flute or indentation to be produced, said die being secured to a plate 15, which is provided with a flat foot-piece 20, fitted to slide horizontally, in a guideway 25 on the table I). The plate 15, carrying the foot-piece 20 and die f, is advanced or pushed forward toward the article to be fluted by a plunger or carrier H, connected with and operated by a screw I, turning within an upright g, rising from the bed A, and provided with a handwheel K, by means of which the die can be advanced as desired. After the article to be fluted is placed against the rest B the die f is brought into contact with its opposite side by means of the hand-wheel K, whereby an indentation of the desired length and depth is produced, the soft metal being depressed or driven in by the die along the line of its edge without distorting or otherwise changing the shape of the article, which is properly Lil supported and sustained during the opera tion of the die by the rest 13. The plunger or carrier II is now withdrawn by turning the hand-wheel K in the opposite direction to permit the die f and plate 15 to be slid back on the table I), after which the article being fluted is turned within the rest B about an axis at right angles to the direction of the movement of the die to bringa fresh portion of the surface of the article opposite to said die, which is again advanced to make another indentation similar to the first and at the desired distance therefrom, the operation being repeated at the desired intervals until the fluting has been produced around the entire circumference ofthe article, which is thus effected without the use of a die and force or any. resistance other than that afforded by the metal being impressed when firmly held in position against a concave rest, as described.

In the apparatus here shown the plunger or carrierII of the press is arranged to operate in a horizontal plane; but it is obvious that it may be arranged to operate vertically, in which case the part 0 would form thebed of the press on which the removable rest B would be placed.

By the employment of the above-described apparatus a great saving of. time and labor is effected, as the filling of the article with pitch is dispensed with and each indentation is made of full length at a single operation of an edge-die instead of by following out-the design of the flute with asmall hand-tool, as hitherto customary. tofore been burnished either by hand or by the use of. a lathe, but the latter method, which is the cheaper, can only be employed on smooth revolving bodies having no indentations or depressions on their surfaces. Hence as it was not possible to properly produce the tinting by hand after the article was plated, hand burnishing only could be employed; but when my improved apparatus is employed the article can be plated, finished, and burnished in a lathe and the flutes or indentations afterward produced,as above described, without injuring or marring the finish in the slightest degree.

It will also be noticed that the table b may be adjusted vertically for articles of different height without changing the relative position of the die, as the die is carried by the table and is not positively connected with the operating-plunger. By slightly retracting the plunger the hollow article resting on the table may be rotated by hand to bring a new surface opposite the die, the opposite side of the article being still supported in the concave rest B.
