Application filed October 5, 1893. Serial No. 487,214. (No model.)

cards and Similar Sheets, of which the following is a specification.

The object of my invention is to provide a new and improved machine for making tubu lar borders or frames from sheet-metal and at the same time, when desired, attaching said borders to display cards, sheets, &c.

In the accompanying drawings, illustrating my improved machine, Figure 1 is a vertical transverse sectional view of my improved machine for making and applying tubular sheet-metal borders on show cards and the like. Fig. 2 is a plan-view of the same, and Fig. 3 is a side view of the same. Figs. 4 to 7 .are detail views of the blades and other parts showing them in different detail and Fig. 8 is a view from below of frame 5 and hinged bar 12,

Similar figures of reference indicate corresponding part-s.

On the supporting-frame l of the machine the two bearings 2 for the driving-shaft 3 are fixed, from which driving-shaft the several parts of the machine are operated. Near the two ends of the. shaft 3 the two eccentrics 4 are mounted and operate the horizontally-reciprocating frame 5,,which is guided in suit-' able ways, 20 to the front edge ofwhich frame 5 the cutting and shaping blade 6 is fastened by means of screws, said blades serving for cutting and shaping the sheetmetal. Opposite the. blade 6 the counterblade 7 is arranged, under which the shaping-blade 8 is mounted, which blade 8 is shifted transversely to its length by means of connecting-rods 19 from cams 9 on the ends of the shaft 3.. Theedge of the shapingblade 8 is shaped convexly, whereas the blade 6 is shaped ooncavely, the adjacent edges of said blades Hand 8 being so shaped as to fit oneach other, so thatfipart of a sheet of metal placed between said blades 6, 7 and 8 is cutoff and at the same time bout the same as the configuration of the edge of said blades 6 and 8. Above the counter-blade 7 the guides 10 for the sheet-metal to be worked are arranged vertically, and said sheet of metal is weighted by a bar 11 resting on the top of the same and between the guides 10.

A flatbar 12 is hinged along one of its edges on the bed-plate 1 of the machine and can be actuated, that is swung into vertical or horizontal position andvlocked in place by means of a system of, levers 21, 21. 011 said flat bar the bottom edge of the metal sheet rests while a strip is being cut from the same by the blades. 6 and 7, the flat. bar being' in horizontal position. The strip cut off by the blade is thus always of uniform width. To prevent frame 5striking against the fiat bar 12 which lies in the same plane with the former, on its forward motion, both frame 5 and bar 12 are recessed so that the recesses of the one receive the lugs formed by the recesses of the other (Fig. 8). The cams 13 on the shaft 3 actuate by means of the lever 14, a presser-bar. 15 reciprocating in vertical guides 22 and placed below the shaping blade 8, which presser-b ar serves for holding the strip of metal that has been out OK against the under side of the blade 8, untiLthe concave surface of blade 6 has formed the same into a tubular rim or border. To prevent the metal stripsheld by the presser-bar 15 (Figs. 4 to 7) from slipping back on the backward movementof the blade8, said presser-bar is cut away to the front, the thickness of one strip, so that the rear edge of the strip comes to be against the projecting edge part 25 of presser-bar 15, and is thus prevented from bein g drawn backward by blade 8. Tothe back of I theframe 7 is pivoted the table 16 and between thejsame and, the blade 8, the show-card or other placard which is to be provided with a metal border can be inserted. After the border has been applied to the sheet, the table 16 is lowered by means of a treadle 24 and treadlebar 17 into the position shown in dotted lines, to permit of readily removing the show-card that has been provided with a rim or border. Immediately beneath, ,the table 16 and attached to a part 27 of the frame, is aspring 2,6 which acts on table 16 and tends to keep it in its normal or upper position when not depressed by treadle 24:. The plate 5 is also 24 and treadle-bar 17, and the bordered sheet provided with a perforating or embossingdie can :easily be removed, the table 16 returning 18 for the purpose of providing the necessary embossing and perforations on the border. The machine thus not only serves for producing tubular metal border strips but also for applying strips at the same time on the sheets or cards.

The drawings show the machine in a position of rest and its operation in detail is as follows: When the shaft 3 is turned in the direction from left to right, the eccentrics and. cams on the same are moved toward the it restsagainst the blade 8 and presses the said strip fir-mly against the molded edge of said blade 8, whereby a half-round shape is given to part of this strip, as shown in Fig. 4. Hereupon both blades 6 and counter-blade 8 slide slightly forward under the influence of cams 9 andconnecting-rods 19, until the front edge of blade 6 forms an almost straight line with the presser-bar15. At the same moment this presser-bar 15 rises under the'action of the levers 14:, actuated by'the cams 13, and the blade 8 under the influence of cam 9, rapidly moves backward a distance required. for properly shaping the tubular border. By the uniform forward movement of the frame 5 with its blade 6 the tube is completed, as the approximately half round bent. portion slides along the concave surfaceof the-blade 6 and-is rolled up into a tube (Fig. 7); At the same time the plate previously inserted in the guidesll is perforated or embossed. Then all the parts return into their original position. If tubular shaped borders only are made, the same when finished drop into a suitable receptacle by turning the flatbar 12 by means of the system of levers-21;

In providing show-cards with tubular bor- 16 is thereupon lowered by means of treadle automatically to its upper or normal position under the*infiuence of spring 26.
