To all 'whom tt may concern Be 1t known that I, `W1LL1AM H. FAHR- Nnr, a citizen of the United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented a new and useful.
Improvement in Sheet-Metal-Bending Machines, of which the following 1s a specie cation.
y to
The object of my invention is to provider a novel and simple construction of machine which shall adapt it for bending sheet-metal into curved shape of any desired radius.
In the accompanying drawingaligure 1 shows my improved machine by a vien7 inA form.
A substantial standard 6, ladapted to be bolted to a suitable foundation, indicated by l the floor-line 7, carries all ofthe operating mechanism. A pair; of massive rectangular bars 8, 8, are rigidly bolted through corresponding end-portions to oppositel faces of the standard near its upper end to extend v horizontallyy vfrom the standard; and these bars are rigidly connected in their parallel spaced relation by a head `9 bolted between their outer ends, the headterminating at itsV upper end in a horizontal bearing 1() for one end of a rotary drive-shaft 11, which is journaled at its opposite end, carrying a crankhandle 12, in a suitable bearing 13 onthe top of the standard. Another bearing, 141, is
provided on the face of the standard below. and parallel With the bearing 13, for the shaft 15 of a roller`16 formingthe support for the Work. Between the bars 8 tit and extend vertically and parallelgwith each other legs 17 and 18 oit' rectangular crosssection containing longitudinal central bores, 111 which are confined, against longitudinal movement and to be rotatably supported, shafts 19 carrying, circular toothed crimping-Wheels 20 on their lower ends and beveled pinions 21 on their upper ends to mesh With beveled gears 22 carried by and adjustable lengthwise ofthe shaft v11. Between the inner legs 17 and 18, are confined jacent-leg-section 27 Y The operation of the machine isn as ol= lows: A channel-shaped strip yot sheet-metal, `"meaning a strip having corresponding pjar-4 l spacing-blocks 23, and these legs are `,clamped between outer legs 24 and 25, havinglovver pivotal sections or members 26 and 27 adapted to svving back and forth,| r
their adjustment, relative to thelegs 17, "18,
and carrying rotatably on their lower endsl otherspacing bloclris'shovvn.. at 29 between the standard G and adjacent legr24/ `The 'itoothedlcrimping-Wheels 28 `to coperatief` `With the wheels 20. In Figs. land f1 an-y legs and spacer-blocks contain correspond-k.
recess shown at 30 in Fig., 3, to embrace one xof the bars 8 and cause the latter to support them against vertical movement While per-v mitting to them movement :lengthwise of the Ving vrecesses in their forward sides, likethe -1 bars 8 for clampingy them together andV loosening them; anda similar but narrower.
recess, like that shotvn at 31, is'providedl in each spacer and leg below the recess '30 plained. For releasably clamping together i the spacers andlegs, a set-screw 32, carry.-
ing a, suitable hand-Wheel'33, is provided to Work in the head 9 against the adjacent leg of the legs and spacers below the bars 8.With one of its sides confined in the recessesl to support it against verticalf movement/While vpermitting i 1t to be Y moved lengthwise` n throughthe medium of a set-screw 'Working in one end of the yoke `against the adalllel edge-flanges, lilre that lshown at 36in Eig.V 5, vexcept that itis straight, and the tlanges are uncrimped, is fed endwise to the therein, 'for the purpose herein-after ex-y j 25; Ayoke 34 extends about the' portions y machine Withwits baseapplied, for support extended between l the opposite ,pairs of ,and guidance, tothe roller 16 and its flanges .j
toothed Wheels 20, 28. The. set-screw 35 is thereupon turned to draw the yoke' 34, in the direction to turn the leg-members 26 and 27 toward eachother and tighten the Wheels 28 against the inserted langesto Vbe crimped. Y
By then` turning the y.handle 12 Yto rotate-the shafts 19 the set of driven .Wheels 2Q advance the strip through the machine and the coprelative to the wheels 20, crimps the iianges and thus bends the strip into curved or, arcgeration of their perpendicular teeth with the teeth of the Wheels 28, which are inclined y j 11o-y .shaped form. Qbviously, iffthe Vteeth of the `cooperating Wheels 20 and 28 Were parallel,
no curvature of the strips would be produced. The extent, meaning shortness or length, or radius, of the curve maybe varied, to shorten it, by tightening the wheels 28 against the iianges thereby to bend the flange-sections more deeply, and thus more of the metal, between the intermeshing teeth, and to lengthen it by lessening such tightening, thereby to bend the 'Hange-sections lessdeeply and thus with less of the metal between those teeth. By thus varying the degree of tightness of the same wheels 28, of course the possible range of variation in curvature is comparatively small, However, the extent of curvature may be that of any desired radius by employing wheels 2S of greater or smaller diameter. The desired result may also be accomplished with the leg-sections 2G and 2T depending perpendicular-ly, or parallel with the legs 17 and 18, provided the peripheries of the wheels be beveled to render the teeth upon them slanting.
What l claim as new and desire to secure by Letters Patent is- 1.111 a metal-bending machine of the character described, the combination of a standard, bars extending in parallel spaced relation from the standard, vertical shafts rotatably supported between said bars, toothed wheels on said shafts, pivotal members supported on said bars to extend inclinedly relative to said shafts, toothed wheels journaled on said members to extend inclinedly relative to said first-named wheels and cooperate therewith to crimp the flanges of channel-form sheet-metal fed between the teeth of the opposing wheels and thereby curve the work, and means for rotating said shafts.
