METAL BENDING MACHINE. No. 313,969. Patented Mar. 17, 1885 z i. minim-m ughnw mm MM 7 time STATES PATENT i -Fries.
ALWILL URBAHN, or PATERSON, NEW JERSEY, ASSIGNOR TO JACOB MAY,
on BROOKLYN, NEW YORK.
METAL-SENDING MACHlNE.
SPECIFICATION forming 'part of Letters Patent No. 313,969, dated Marchl7, 1885.
Application filed May 31, 1884. (No model.)
To all whom, it vita/y concernr Be it known that I, ALwILL URBAHN, a resident of Paterson, in the county of Passaic, and State of New Jersey, have invented an Improved Metal-Bending Machine, of which the following is a full, clear, and exactdescription, reference being made to the accompanying drawings, in which Figure 1 is a plan or top view of my im- 1 proved metal-bending machine. ,Fig. 2 is a side elevation of the same. Fig. 3 is a partial top view of the bending parts thereof, showing the latter in a different position from that represented in, Fig. 1. Fig. 4 is a side 1 5 View, and Fig. 5 a face view, of a strip of metal bent into shape.
The object of this invention is to produce a machine in which iron or other strips-such as are used for making window-gratings or 2 grated doors, ornamental railings, &c.-may be conveniently bent without causing undue friction, and, if desired, after having been punched or perforated.
Heretofore, so far as I am aware, such bending has been performed in machines in which the metal was laid over a matrix and beneath a die, which, when brought down,would crowd the metal into the matrix and pull and strain it, even stretching it, the stretching being sufo ficient to make it' impracticable to punch the holes through the metal before the act of bending, as they would, after the metal was bent, not be in the proper positions. In my machine these difiiculties are avoided by the employment, principally, of a divided matrix, if it may be so termed, of which the parts move sidewise toward the die or patrix during the act of bending the metal, thereby avoiding all strain upon the metal, except that necessary 0 for bending and insuring'an exact result.-
In the drawing, the letter A represents the frame of the bending-machine, in which frame is hung a driving'shal't, B, to which rotary motion is imparted by suitable means. The
4 5 said driving-shaft, by gear-wheels a b, imparts rotary motion to a shaft, 0, which carries two equal cams, d d.
To the frame A are pivoted the lower ends of a vibratory frame, D, the uprights of which frame are, by springs e, held in contact with the cams d d. By revolving the shaft 0 the frame D will be oscillated on its pivots g by thejoiut action of the cams d and springs e,
or equivalent weights. The vibrating frame D connects by rods f with a transverse plate 5 5 or beam, E, which is slid back and forth by its connection with the frame D, and which is guided under slotted blocks 71, that are fasten ed to the frame A of the machine. Between these blocks h (see Fig. 1) there is fastened to 6) the beam E a U-shaped brace, i, which bears against the inner faces of the blocks h and steadies the beam E in its reciprocating movements laterally. To the beam E is likewise fastened, by suitable bolts, the patriX or shap- 6 5 ing-die F of the bending-machine. The oscillating frame D connects also by rods j j wit-h two levers, G G, which are pivoted by the single pivot to the frame of the machine, and
to which are secured the shapers or bending 70 parts H H, which together form the matrix of the bending-machine. The rods j may either extend from the beam E to the levers G G, as
is shown in Figs. 1 and 3, or these rods may extend from said levers G G directly to the frame D.
The machine operates as follows: WVhen the frame D is swung back-that is, as near to the shaft 0 as possible-the beam E will be moved as faraway from the pivot 76 as possible, which 80 will leave the parts F H H in the position shown in Fig. 3. The patrix F may have a small prong, Z, affixed to its central projecting portion. The bar of iron to be bent is placed transversely across the face of this patrix F, 8 as is indicated by dotted lines in'Fig. 3, and if this bar has first been perforated it is so lo cated against the patrix F that the prong Z will pass through one of said perforations. The shaft 0 being now revolved, the parts F co H H are made to approach each otherthat is to say, the part F or patrix moves longitudinally, while the sections H H of the matrix approach it from opposite sides in the arc of a circle, until finally the position shown in Fig. 1 is attained, in which the piece of metal held between the parts F H H is shown to be bent in correspondence with the outline of said pieces. Upon the cams d receding from the frame D, the bending parts are opened, and ICC the bar of iron or other metal to be bent may be further pushed along, so that the outline shown in Fig. 4 may be produced, or any other suitable form.
I deem it an important feature of my invention that in the bending-machine the parts H H approach the reciprocating part F from opposite sides, and constitute, after having approached it, a substantial equivalent for the usual matrix.
WVhat I claim is v 1. In a bending-machine for bending metal, the combination of the patrix F with the bend ing-levers G and single pivot is for said levers, and with the reciprocating beam E, rods j, and rods f, for simultaneously moving the patrix and the levers G, substantially as herein shown and described.
the rods 7', levers G G, and bending devices H H, all arranged for operation substantially as described.
ALWILL URBAHN.
