MEANS FOR ORNAMENTING SHEET-METAL ARTICLES.

SPECIFICATION forming part of Letters Patent No. 482,837, dated September 20, 1892.

' Application filed April 30, 1892.

To all whom it may concern:

Be it known that we, BERNARD M. ABELL and WILLIE OSTRANDER, citizensof theUnited States, and residents of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Means for Ornam enting Sheet- 7 Metal Articles, of which the following is; a

specification.

The invention relates to improvements in means for ornamenting sheet-metal articles, such as bowls, pitchers, cane-handles, and the like, which articles in the larger silverware factories are usually ornamented by snarling and other slow and tedious forms of labor.

The invention consists in the devices and.

combinations of parts hereinafter described and claimed; and its object is to produce suitable apparatus whereby under the action of hydraulic pressure the plain walls of a bowl or other article may have imparted or.

and a novel press for maintaining the sections of the .die under the great pressure necessary to properly effect the transfer of the design from the walls of the matrix to those of the bowl or other article therein.

Our invention pertains particularly to the vertically-reciprocating cylinder above referred to, with its attendant devices, and to the press sustaining the sectional die.

Referring to the accompanying drawings, forming part of this application, Figure l is a central vertical section through an apparatus constructed in accordance with and embodying the invention. Fig. *2 is a transverse section of same on the dotted line 2 2 of Fig. 1, looking downward. Fig. 3 is a detached perspective view of one of the followers and platens, constituting a portion of the press for maintaining the'die. Fig. 4 is a detached transverse section on the dotted line 4 4 of Fig. 1. Fig. 5 is an enlarged central vertical Serial No. 431,324. (No model.)

section of the lower end of the vertically-reciprocating cylinder which enters the die. Fig. 6 is an enlarged detached central vertical section through a portion of one of the followers and the means whereby it is secured to its 0 crating-screw, and Fig. 7 is a central vertica section of a bowl in the nature of a blank adapted for treatment in the die.

In the drawings, A designates the bed-plate, of the apparatus, B the top frame thereof, and O O the vertical rods or standards connecting said bed-plate Aand top frame B and having between their upper portions the transverse frame D, which supports the hydraulic jack E, of usual construction. Upon opposite sides of the lower end of the ram F of the hydraulic jack E are provided the lugs G, from which is suspended by means of the links H the plunger I, having upon its lower end the customary cup-shaped packing J. The upperend of the plunger I at opposite sides is provided with the lugs K, which correspond with the lugs G and receive the ldwer'ends of the links H, and said upper end of the plunger I is broadened to olfer an edective bearingsurface for the lower end of the ram F when the latter is depressed thereon.

It will be observed upon reference to'Fig. 1 that the length of the links II is such that the plunger I is dropped a short distance below the lower end of the ram F, and hence upon the descent of the ram and plunger the latter will be lowered upon the liquid and the former will thereafter travel downward a short'dist-ance before the full pressure of the ram is transmitted to the plunger.

The bed-plate A will be properly supported upon a base L and is provided at its center with the aperture M to receive the pin N, extending centrally downward from the baseplate 0 of the sectional die I. The bed-plate A is also provided at its corners with the internally-threaded bearings Q for the'screws R, which are horizontally arranged and provided at their outerends with suitable handles S, by which they may be operated. The screws R extend inward on direct lines toward the opposite sides of the sectional die P and carry upon their inner ends the followers T and plates or platens V, the former being provided with the dovetailed grooves V to receive the morrespondingly-formed ribs X I), screwed to said followers.

upon the outer face of the platens V. The

inner extremities of'the screws Rare threaded to receive the collars Y, which are adapted to enter the cavities a, formed in the outer face of the followers T and to be held there in by means of the internally-threaded nuts In the arrangement of the screws R, followers T, and nuts I) we first pass the inner extremity of the screw R through the nut 12, then apply the collar Y to the end of said screw, and thereafter insert the said collar Y into the cavity a and screw up the nut 12, thereby securely retaining the whole in place. The arrangement of the screw R with the follower T is such that the parts may be separated, when desired, for repairs or for other purposes. The lower surfaces of the followers T are provided with the ribs (1 and rollers e, the former extending downward and being adapted to travel in the grooves f, formed in the bed-plate A, while the rollers 6 move upon the surface of said bed-plate and facilitate the rollers g to aid in their adjustment toward adapting them to the size of the dies.

adjustment of the screws R and followers T toward and from the sectional die P. The bedplate a is provided with four of the screws R, and each carries the follower T and platen V. The platens V are also provided with and from the sectional die P, and said platens Y are adjustable laterally by means of the ribs X and grooves W for the purpose of ing. them together, and within 'the die P,, whether composed of the specific sections hor'of sections otherwise formed, is provided the matrix n, whose surfaceswill be engraved p with the design it is intended the finished article shall bear. Above the matrixn there is provided in the die the central opening if, having vertical walls and a base. it, which inclines inward toward the center of the matrix at, thereby forming the inclined surfaces terminating at the edges of the opening to. The sheet-metal article to be treated in the die will conveniently fit the matrix 12 and have upon its upper end the flange ac, which will rest upon the inclined surfaces of thebase u of the central opening t. I

At a suitable elevation above the sectional die P there is secured tothe standards C the transverse frame A, having the central vertical opening B and held in place by means of the brackets O" and screws D, the latter being adapted to enter any of the series of apertures F pr vided in the inner faces of the standards 0. The purpose of providing a series of the aperturesF is to permit theadjustment of the frame A upwardor downward, in accordance with the height of thesectional die and other circumstances. Within The the opening B in the center of the frame A and the vertical exterior grooves L, receiving the inner ends of the arms M, which arms, in connection with said grooves, insure a direct vertical movement in the cylinderJ and prevent any revolving motion thereof. The arms M are bolted to the lower surface of the frame A and will be of convenient form and size to pass below the internally-threaded sleeve G and properly engage the said grooves L, formed in the opposite sides of the cylinder J. The lower end of the cylinder J is reduced to form a threaded stem N and has the annular recess 0, which receives the angular packing P, and the upper portion of the nut Q, screwed home upon the said stem N. The formation of the packing I and nut Q is of importance, since it is essential that the liquid within the bowl inclosed in the die P be most securely held; otherwise it will escape under the actionpf the hydraulic pressure.

It will be observed upon referenccdo Figs. 1 and 5 that the lower surfaces of the nut Q taper downward and inward and that above said tapered surfaces thecnut is provided with the annular recess S to receivethe inwardly-tapering lip T of the packing P.

'VVhen the cylinder K is lowered into the die 7 P, the lower extremity thereof will enter the opening w and the nut Q and packing P will engage the flange a: of the bowl, and

when the parts are inthis position the annular lip T of the packing I will'bear against theflange w of the bowl and form a liquidtight joint. Any water risingvaround the lower end of the cylinder J and nut Q will pass beneath the annular lip T and more firmly press the same against the flange 0:, thus effectually sealing the joint and preventing all leakage. The packing P is of angular form in vertical section, as shown,

and is securely held inplace by the not Q, which is adapted to be removed and leave the packing in condition to be withdrawn when desired. I i

In the operation of the apparatus the bowl or other article it is desired to shape or ornament will be placed in the previously-prepared die and'the latter then seated upon the bed A and there securely held by the platens V, which will befirmly backed by the screws R. The bowl and die being in position, the

cylinder J willbe lowered by the rotation of and the ram of the hydraulic jack lowered, causing the descent of the plunger I through the cylinder J and upon the liquid in the bowl. .The pressure of the hydraulic jack being continued, its force, acting through the plunger I upon the liquid, will swell the walls of the bowl into the interstices of the die, and thus the bowl at a single operation will have imparted to it the form of the matrix and whatever design, whetherin intaglio or relief, the walls thereof may bear. After the bowl has thus been shaped and ornamented, the ram F and'plunger I will be elevated and the cylinder J raised by the reverse rotation of the sleeve G. Thereafter the platens V, by the reverse rotation of the screws R, will be drawn outward, and the die thus left free will be removed, its sections separated, and the bowl withdrawn. Another bowl with plain surfaces may then be placed in the die and the latter sustained by the platens V,,while the above-described opera tion of lowering the cylinder J and plunger I is repeated. The dies as to form, size, and design will varywith the conditions it is desired to produce in and the nature of the article under treatment, and hence it will be understood that the platens V should be adj usted on the followers T in accordance with the size of the die. It will be observed that the platens V are equal in length and that they overlap each other at one end, thus permitting their adjustment to inclose'a very small die centered on the bed-plate A.

WVhether the platens V are adjusted to close about either a large or a small die, the screws R will exert their pressure on direct lines centrally against the opposite sides of the die and firmly bind the same. The platens V and screws R constitute a press for holding the sections of the die with the requisite firmness for resisting the great force of the hydraulic jack and form an important feature of the invention. It will not be necessaryin every instance to employ four screws R and four platens V,and hence the invention is not confined to any special number of the screws and platens; but that number thereof will be used which may be required by the varying forms of the die-sections.
