Serial No. 12,818, filed March 25, 1935 (now Letters Patent No. 2,160,999, dated June 6, 1939). For this purpose the shafts 52, 53, slidably fit into and are keyed to sleeves 66 (Fig. 9) to rotate the latter. Eacn sleeve is provided at its inner end with a collar 61 to which the adjacent trimming device 64 is removably secured by bolts 64a. Be-
tween the sleeve 66 and the adjacentbox 54 is provided suitable anti-friction bearing elements No claim is made herein to the mounting of pit C and having oppositely inclined walls forming waysfor, grooves 61 formed in the lower end of the standard 5|. The sills 86 are formed with longitudinal T slots for bolts 88 by means of which the standard may be adjustably secured to i the sills. 89 indicates a threaded opening formed the trimming devices, the assembly of such mounting with the journal boxes and adjustment of these. parts with the adjacent standard as that forms in part the subject matter of the aforesaidapplication.
The slitting devices 65 are mounted for adin the standard 5| and arranged to receive a feed screw 9ll,'which, when rotated and upon loosening of the bolts 88, serves to move or adjust the standard alongthe sills 86. The outer end of the screw is preferably power driven, such end being mounted in the side walls of a casing 91 and fixed to a worm gear, 92 disposed between said side walls, the gear in turn meshing with a worm fixed to a shaft 93, which is driven by a motor 94. V
I As the material A moves to and through the trimming and slittingmechanism 3, its marginal edges are trimmed off by the devices 64 and cut justment axially of the shafts and for movement or slit longitudinally by the devices 65. As only one set' of slitting devices are shown, the material A may be cut into two sections of equal or By positioning the devices 65 in an in-operative position, the slitting operation may be omitted one or more threaded openings for suitable screws 69' arranged to project into and engage the bottom wall of the keyway formed in the adjacent shaft to lock the member 69, in its adjusted-position. The outer wall of the member 69 is formed with annular grooves forming races for balls 10. 1| indicates an annulus formed on its inner wall with races concentric to the adjacent shaft and rotatable 'on the balls 10. The outer wall of the annulus 1| is formed with races 12 for balls 13, which races are eccentric to the shaft axis. 14 indicates a ring-forming a support for the adjacent slitting device 65, the inner wall of the ring 16 being formed with races to engage the balls 13 and permitting the ring and its slitting device to freely rotate around the annulus 1|. The annuli 1| 'are arranged, when in one position, to support the slitting devices in operative relation, as shown in Figs.
sembly. Each annulus 1Imay be locked in either I position. For this purpose each annulus is provided with an arm 15, notched at its outer end to removably receive a locking device 16 whenin .either position. Each locking device comprises a rod slidably supported at its opposite ends in horizontal guides11 provided on the inner walls of the standards 50, 51. Each rod 16 may be held certain of the gears serving to rotate the scrapas the material feeds forwardly.- As the trimming and slitting devices are mounted on the same shafts, these operations areeifected simultaneously but this arrangement is not an essential feature of my invention. The trimmed-off marginal edges are directed downwardly to the scrap cuttinglmechanism 6, which is shown diagrammatically and preferably is' similar to that .shown in my aforesaid co-pending application.
into a receiver D (see Fig. 1).
From the trimming devices 64 and slitting devices 65, the material A is guided by and between pairs of guide members 3a to a set of feed rolls 95, which are preferably driven in the following manner through a. gear train within a casing 34a,
- a gear 99 fixed to the shaft of the scrap cutter in the notch'of the adjacent arm 15 by a ,set
screw 18. A gear 36 is fixed to the shaft 53,
' and meshes with a gear 360. fixed to the shaft 52 to 'drive the latter. The shaft 53 is connected 96'. The gear 99 through idlers I00 and Ill! drives a gear I02 fixed to the shaft of the lower feed roll and the gear I62 meshes with a gear "12' fixed to the'shaft of the upper feed roll 95.
From the feed rolls 95 the sections a pass to the edge conditioning or finishing mechanism 4 I having a plurality of sets of devices, one set for each section a, two sets being herein shown and indicated at I03, l63a. As the sections a are in edge to edge relation when slit, the sets of devices I09, lllia, are so arranged that they may condition, finish or round the side. edges of both sections simultaneously, while providing for the conboth sections are guided to and fed in spaced planes above and below the plane in which the material moves through the leveling mechanism 2 and trimming and slitting mechanism 3, and the sets of edging devices are in these spaced planes, respectively. The sets of devices I03, I030, are positioned in different horizontal planes and spaced longitudinally of the material as shown in Figs. 2, 4 and 6 or in the same transverse plane as shown in Figs. 22, 23, 24 and 25.
. Referring to Figs. 2, 4, 6, 16 and 1'7, I indi-' cates standards suitably mounted on a base Ililla. I08 indicates a U-beam having end walls suitably secured to the standards I04. I01, I01, indicate a pair of supports provided on their opposite sides with lugs removably and adjustably secured to the sides of the beam I06, for supporting one set of finishing or edging devices (set I 03) Each support isformed with an opening I 08 and its plane. Each section a as it leaves the trimming .and slitting devices is rough and provided with burs, so that by passing the section to and between a pair of edging devices the metal of the edges is finished, smoothed, conditioned or rounded as may be desired, to eliminate the roughness and burs and condition them for welding or other purposes, As shown in Fig. 20, the edges of the section may be finished to be disposed at right angles to the surfaces thereof or, as shown in Fig. 21,. these edges may be rounded. By preference, I, associate with the edging devices a pair of holders I I0 which engage the upper and lower surfaces of the section to prevent distortion or buckling of the section while being engaged by the edging devices. In the form of construction shown in these views, the holders comprise a pair of freely rotatable rolls H0. The axes of the rolls III! are disposed in the plane cutting the axes of the edging devices I001). The rolls IIO are provided at their opposite, ends with stud shafts which loosely rotate in bearings provided in the upper and lower walls of the supports I01. III, H2, indicate pairs of driven feed rolls disposed forward and rearward of the set of edging devices I03 and serving to guide and feed the section in the plane of the grooves in the devices I03b'. From the feed rolls N2 the section a passes to and between a Y indicates a worm gear in mesh with a wornfixed -to the shaft 84. The worm gear- H4 is fixed to a shaft I I5 carrying a pinion 5a which is in mesh with a gear H6, the gear in turn being fixed to a shaft I IBa (see Fig. 4 The shaft litia is connected through a coupling III to one end of the shaft of a guide and feed roll IIB to which reference will later be made. The opposite end of the shaft for the roll H8 carries a gear HS (Fig. which meshes with a gear I22 fixed to the upper feed roll III. The gear I meshes assaesa with a gear I20a fixed to the shaft for the lower feed roll I i I and the latter gear, through an idler I2I drives a gear I22 fixed to the shaft for the lower feed roll 2. The gear I22 meshes with a gear I22a fixed to the shaft for the upper feed roll H2.
The other section a of the material is. guided and fed by the roll II8 (already referred to) and. a plate I23 to the set of edging devices I03a. The
plate I 23 is mounted on a cross bar I23a secured at its ends to the standards 04. The set of devices IBM is arranged in a plane above the set I03 and spaced longitudinally of the direction of feed of the material, but in alinement with the adjacent section a. The set of devices Ilila comprise opposite related edging devices constructed and mounted similarly to the set of devices I63 already referred to, to engage the opposite edges of the section and have associated with them holders III! which engage the adjacent section a in line with the edging devices, these rolls being constructed and mounted in the same manner as the rolls III). III, II2, indicate pairs of feed rolls disposed forward and rearward of the set of devices I03a. The feed rolls III', 2', are mounted similarly to the rolls III,.
H2, and are driven as follows (see Fig. 15): I20 indicates a, gear fixed to the shaft for the lower feed roll III and in mesh with and driven by v the gear I22a. The gear I24 also meshes with a gear I24a fixed to the shaft for the upper feed 'roll III and with an idler I25. The idler! meshes with a. gear I26 fixed to the shaft for the lower feed roll 2' and the gear I26 in turn meshes with a gear I260 fixed to the shaft for the upper feed roll 2'. The gears above referred to are enclosed in .a suitable casing I21 (see Fig. 4).
Figs.- 22 to 25, inclusive, show a modified form of construction in which the sets of edge finishing devices, the adjacent alined rolls and the front and rear feed rolls for each set are disposed in the same transverse plane but spaced in different horizontal planes in alinement with the sections a, respectively. In this form of construction the standards may be formed in sections 104:, lfllz' (see Figs-23 and 25). The upper set of edge finishing devices I03z and the alined rolls and the front and rear feed rolls are similar to like parts already described and the corresponding parts of the lower set I031." and the parts associated therewith are also similar to those already referred to, except that the upper feed rolls IIIr, Il2x,are not adjustably mounted, whereas the lower feed rolls iIIx, 2a: are adjustable vertically. The journal boxes for the upper-rolls II Ir, 2.1:, fit into openings I20 and rest on lugs I28 fixed to the outer walls of the standards and are held thereon by lugs I280 fixed to and depending from the flange IZBbof the upper standards I040? which is suitably bolted to the lower standards Iiitx. The journal boxes for the shafts of these lower feed rolls slidably fit the openings I28 in the standard sections I041; and engage wedges I28" which are operable in ways at the lower ends of the openings and when moved endwise raise or lower the adjacent journal boxes. Each wedge I28" is constructed to rotatably but non-slidably support a shaft I29, shaped at its outer end to take a suitable tool to effect a rotation of the shaft and provided at its inner end with threads and engaging a threaded opening formed in the adiacent standard section, whereby rotation of the shaft I29 will eflect movementlof the wedge is.
which co-operates with a roller 'walls of the bed I39.
either direction. In this form of construction, the shafts for each'pair of feed rolls are drivingly connected by "gears I33, I3I, respectively I (see Fig. 23). The gears I3I connected to the shafts for the lower feed rolls related to the upper edge up-setting devices are in mesh with and driven by an idler I32 which is driven by a gear I33. The gear I33 is in mesh with and drives the gears I33 connected to the shafts for the upper feed rolls related to the lower edge upsetting devices. The gear I33 is fixed to a drive shaft I34. The shaft I34 may be connected to the driven shaft 84 as ah'eady set forth in connection with the shaft IIIia or driven by a separate motor,
The re-coiling mechanism comprises the following: I35 indicates a pair of spaced standards mounted on a support or base I35a. I33, I31, I33, indicate a set of driven rolls between which the sections a, a, feed in side by side 'relation (see Fig. 5), these rolls being so arranged that they co-operate to bend or curve the sections as this feeding takes place. The shafts for these rolls are suitably mounted in journal boxes mounted in the standards, the boxes for the shafts of the.rolls I31; I33, respectively, being adjustable to insure the desired curvature, so that the sections, will readily wind into coils A, as shown. I 39 indicates a bed mounted on the base I35a forward of the standards I35. At
its opposite ends the bed is formed with upstanding lugs I40 having openings to receive and support a rod or shaft I4I, on which is pivoted a shelf I42. The shaft I4,I supports a roller I43 mounted on the outer end of the shelf I42, to support the coils A. As the rollers I43, I44, are free to rotate, they permit each coil to rotate about its axis due to the feed of the section a from the rolls I36, I31, I38. The shelf I42 is supported at its outer end by a pair of screws I45'threaded through openings formed in the The screws I45 are provided with hand wheels I46 for rotating them to swing the shelf upwardly to a desired position to accommodate the coil when the first convolution thereof is produced. As the coil A increases in diameter, due to the progressive coiling action,
the shelf I42 may be adjusted downwardly to able gearing in a casing I41 by ashaft I43, the
shaft being driven through reducing gears I48 by a shaft I50, which in turn'is driven through a worm and worm gear by the shaft I5I of a motor I52.
It will be understood that the driven elements of each mechanism have the same peripheral speed and that these elements of all the mechanisms are driven at speeds which insures a uniform feed of thematerialto prevent slack or buckling thereof while-passing from one mechanism to the other.
