DEVICE FOR FORMING ANNULAR SHEET lVlETAL RINGS.

SPECIFICATION forming part of Letters Patent N 0. 595,287, dated December 14, 1897.

Application filed April 27, 1897- Serial llo. 634,079. (No model.)

To aZZ whom it may concern.-

Be it known that 1, JOHN A. CARLSTEDT, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Attachments orDevices for Forming Annular Sheet-Metal Rings; and I do hereby declare the following to be a full,

clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates more particularly to a novel construction of apparatus or device for forming circular metal rings from a continuous piece of flat and straight sheet metal, said apparatus being intended for use in connection with that class of machines known as beading-machines.

The present invention has for its primary object to provide an apparatus or device of the nature hereinafter specified, working in conjunction with the beading-rolls of a head in g-inachine, wherebyastraight and flat piece of sheet metal which is fed between said rolls is suitably ornamented and beaded and at the same time is forced into the shape of a flat annular ring.

Heretofore flat rings of sheet metal were cut in short pieces by means of a hand-shears, being suitably curved, and such pieces, usually four, five, or six of them, were then placed end to end and soldered together to form the completed fiat annular ring, or such pieces had to be forced from the blank of sheet metal by means of suitable dies and then soldered end to end, as stated. This method of producing fiat rings of comparatively large diameter, was slow and tedious, as well as expensive.

A further object of this invention, therefore, is to obviate these objections and provide a band or ring having a better and more finished appearance.

With these several objects in view the invention consists in the novel construction of attachment or device for forming annular rings of sheet metal, as well as in the novel arrangement and combination of same with the rolls of a beading-machine.

The invention consists, furthermore, in the details of construction and the peculiar combinations of the parts of the apparatus or device forming my invention, all of which will be hereinafter fully described, and finally embodied in the clauses of the claim.

The invention is clearly illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of a heading machine, illustrating in connection with the same my novel form of ring-forming device or apparatus embodying the principles of my invention. Fig. 2 is a top or plan view of the apparatus or device. Fig. 3 is an end view of the same when looking in the direction of arrow at in Fig. 2; and Fig. at is a cross-section, taken on line y y in said Fig. 2, when looking in the direction of arrow 2 Fig. 5 is a bottom view of the ring-forming device or attachment, and Fig. 0 is a detail view illustrating a cross-section of the lower beadroll axle and that portion of the framework of the beading-n1achine and one means of securing the ring-forming device or attachment in its operative position on said portion of the framework of the beading-machine.

Similar letters of reference are employed in all of the above-dcscribed views to indicate corresponding parts.

In the accompanying'drawin gs, A indicates the general construction of a beading-machine comprising the usual frame portions a and a and operating mechanism a for operating the j o urnals b and I), which are respectively provided with the feed-rolls b and if, as clearly illustrated in Fig. 1. My novel construction of device or apparatus for forming a flat strip of sheet metal into a circular shape as it passes between said rolls 7/ and b consists, essentially, of a flat plate 0, forming a table, and has an opening 0 through which the contacting surfaces of the rolls and b project for properly forcing the sheet-metal band cl over the upper surface of the table 0 when the machine is in operation. lhe under side of said table 0 may be provided with suitablyarranged strengthening-ribs c and a pair of clamping-leaves 0 having the curved surfaces c", adapted to be fitted around and en1- brace the frame portion a of the beadingmachine A and clamped in its operative position by means of a bolt 6 and nut e passing through the perforated ears or lugs c on said clamping-leaves 0 all of which is clearly illustrated in Fig. 6 of the drawings.

Secured upon the upper face ofthe table 0, by means of screws f passing through aperforated flange f, or in any other well-known manner, is a guidef, having the u pwardly-extending guiding edgesf extending back contiguous to the edge a of the opening a in the plate or table 0 and terminating in a suitablyconstructed bearing portion f as clearly shown in Figs. 2, 3, and 6. Said guide is also provided with an extra guiding lip or flange f projecting at a right angle from said edges f said lip or flange being approximately parallel to the uppersurface of said table, whereby a strip of sheet metal can be laid on its flat side on said table and passed beneath said lip or flange f, as clearly illustrated in Fig. 1.

When a wide strip or band of sheet metal is to be formed into an annular flat ring, a second guide 7L may be employed, said guide having the 3 -shaped guiding portion h and being adj ust-ably secured by means of screws or bolts 7L2 and nuts 71/3 in a pair of slots 0 in the plate or table 0, as clearly represented in Figs. 1, 2, 4, and 5. Thus it will be evident that said guide h may be adjusted so that its guiding portion 71 will readily grip the edge of the sheet metal,and said metal thus passing between the two guidesfand h is prevented from buckling, as will be understood.

As will be more especially seen from an inspection of Figs. 2 and 3, the said table or plate 0 is provided with a suitable scale or index, as 0 and adjustably arranged above said plate 0, by means of screws or bolts g and g passing through suitable slots 0 and c in the table or plate 0, is a plate i, and secured in like manner to the under surface of said table or plate 0 is a second plate j. The plate i is slightly raised in the middle and has secured thereto in any well-known manner a pair of guide-plates t" and i connected means of a U shaped guiding-surface 2' against which the edge of the sheetmetal strip or band d is passed as it is fed from the rolls b and 11 between said guide-plates t" and 4?. At one end of said plate 1' is an upright or post arranged in a bearing portion f' of the guide f, whereby when the bolts or screws 9 and g are slightly loosened the plates 2' and j, as well as the guide-plates i and t connected with the plate 11, can be moved laterally by means of a suitable rod and handle i and a pointer t on a projection or other suitable part of the guide-plate 2' set at any desired point on the scale o As an extra precaution to prevent the metal from buckling a second plate 70, having a U-- sha ed guiding ortion k,ma be em 10 ed P P y P y 1 said plate having a perforated projection and a screw or bolt 70 and nut 70, passing through a slot 6 in the plate or table 0,

whereby said guide 70 can be adjusted and secured at the proper angle on the upper surface of the. table 0, as will be clearly understood.

To prevent the end of the strip or band of metal from passing down through the opening 0 in the table or plate 0, the guide-plate t" is provided with a lip or projection, as i which extends over said opening, as shown in Figs. 2 and 5, and to a position in close proximity to the contacting surfaces of the two rolls (2 and h The operation of thehereinabove-described device or apparatus is very simple and will be readily understood, being perfectly operative for the purposes set forth of making from a continuous flat strip or band of sheet metal flat annular rings of different sizes and widths.

It will be understood that changes may be made in the arrangements and combinations of the several parts, as well as in the details of construction thereof, without departing from the scope of my present invention. Hence I do not limit my invention to the exact arrangements and combinations of the parts herein described, and illustrated in the accompanying drawings.
