RICHARD A. BREUL, OF BRIDGEPORT, CONNECTICUT, ASSIGNOR TO THF BRIDGEPORT CHAIN COMPANY.

FEEDlNG MECHANISIVI FOR BLANKlNG-PRESSES.

PEGFICATION forming part of Letters Patent No. 395,211, dated December 25, 1888.

Application filed May 8, 1888. Serial No. 273,182. (No model.)

T0 all whom, it may concern:

Be it known that I, RICHARD A. l-REUL, a citizen ol' the United States, residing` at `Bridgnmort, in the county of Fairfield and State ot' Connecticut, have inventel'l certain new and useful Improvements in Feeding lllechanism Yfor fl'lanking-Presses; and I do hereby declare the lfollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertaiiis to make and use the same.

My invention has for its object to produce a device ot' this class that will cut blanks longitudinallyof a strip of metal which is passed from side to side under the plunger, then ted forward, and passed back aga-in, these movements being repeated continuously, the forward portion ot each alternate row ot' blanks being eut from portions ot' the strip of metal lett between the row of blanks last cut, thus reducing the amount ot scrap to the minimum and Yfurnishing blanks with the grain ruiming longitudinally thereof, which is an important advantage when they are to be used iu places where tf nsile strength is required-as, li'or example, in the manufacture ot" sheet-metal chain. It will oI' course be understood, however, that my improved machine is adapted to general blanking purposes without regard to the shape or size of the blanks or the use tor which they are intended, the especial objects gained being rapidity ot' operation,minimum waste ot' metal, and the securing ol' the maximum tensile strength in the blanks.

My invention furthermore ctmsists in combining with the tir-oding mechanism a cutter which chops the scrap up into small pieces, thereby increasing its value `for melting up without necessitating a special operation to cut it.

lVith these ends in viewI have devised the -rear elevation, the front feed-pawl bracket and tliiecutting mechanism being` omitted; Fig. Jr, a side elevation, the view being from the left in Fig. 2; Fig. 5, a section on the line which may be ot' the ordinary or any preferred construction, they having nothin what-ever Y to do with the principle ot" my invention.

The part-s ot' my novel feeding mechanism may be attached to an independc-mt plate or directly to the bed of the press. In the press ent instance I have shown certain. of the parts as carried by a plate, 4, secured to the bed of the press by screws 5.

t denotes a plaie having an opening, 7, through it, which is adapted to slide in ways 8 on plate Jr.

9 denotes dogs attached to plate G and extending forward toward the front, where they are connected by a cross-piece, 10, the purpose of which will presently be fully eX- plai ned.

11 and 1;? denote, respectively, the upper and lower feed-rollers, both ot' which are roughened at the center, as shown, andare journaled in blocks 13 between pairs of standards Il, the upper blocks resting on spring' 15, which act to lift the upper roller, separating them slightly, so that a strip of metal may be inserted or removed when pressure is removed from the block.

1G is a removable cross-pieee between the standards at the top.

17 an adjusting-lever having upon its upper side curved grooves 1S, the ends of said grooves forming inolines, as clearly shown in Fig. f). This lever is journaled on a pin, 19, projecting downward from the cross-piece, which also carries set-screws 20, adapted to engage the groove in the top of the lever.

21 is a spring cross-piece lyingbetween the standards, its opposite ends resting upon the blocks in which the upper feed-roller is journaled. It will be clearly seen that when adjusting-lever-l7 is turned so that the points of the set-screws engage grooves 18 springs IOO l5, upon which the upper blocks rest, will act to raise said blocks, lifting the upper roller away from the lower roller, as in Fig. 7, and that when the lever is turned so that the points of the set-screws ride up the inclines upon the full thickness of the lever the spring cross-piece and blocks in which the upper roller is journaled will be forced down, placing the upper roller in operative position, as shown in Figs. 4 and 5. The pressure of the upper roller upon the strip of metal may be adjusted by turning' the setscrews in o1' out. The spring of cross-piece 2l inv use is amply sut'tieient to comj'iensate for any irregularities in the thickness ot' the strip of metal that is being' fed to themachine, so that stoppage cannot occur from that cause. The standards are made integral with a plate, 22, which slides in ways in a plate, 23, secured to the bed ot the press, plate 22 being held in operative position by plates 24. (See Figs. l and 2.)

25 denotes notches in the dog fl at the right of the machine, (see Fig. 1,) which are engaged by standards i4, so that plate 22 an d the entire feeding' mechanism are caused to move with plate 6, the strips, and crosspiece l0.

26 is a block having a longitudinal groove, 27, to receive the female die 2S, said die being held at the desired adjustment by a key, 29.

30 is a stripper secured to the block, under which the strip of metal passes in the operation of blanking, there beingl just space between the die and stripper for the metal to pass freely.

It will of course be understood, although not shown in the drawings, that the block is open under the die in the usual manner, so that the blanks when cut drop out below. Stripper 30 is provided with an opening', 3], through which the male die passes as it descends, the stripper acting to prevent the strip from being lifted by engagement with the male die.

32 is a guide-roller on the left dog 9, and 33 guide-rollers carried by a slide, 34, which is secured to cross-piece l0 and slides in a crossgroove, 35, in block 2G as the parts move backward and forward in the operation of feeding, all of which will presently be more fully explained.

In order to provide for slight variation in the width of the strips of metal and to enable me to hold said strips Iirmly, l place one of the rollers 33 on a slide, 3G, dovetailed to cross-piece 34. I The slide is held in place by a screw, 37, passing through a slot, and is forced forward into operative position by a spring, 3S, bearing against the rear end of the slide. The shafts of the feed-rollers are provided with gear-wheels 39, meshing with each other, and the shaft of the lower feed-roller is provided at its opposite ends with ratchets 40, which are engaged by hooked pawls 4], pivoted to brackets42, depending from the plunger.v In the present instance the brackets are shown as connected to arms 43, said arms being rigidly secured to the plunger.

44 denotes springs secured to the brackets and bearing against the backs of the pawls to hold them in operative position, as clearly shown in Figs. 2, 3, and 4.

45 (see Figs. l and 2) is a spring-pawl secured to one of the standards and bearing against one of the ratchets to prevent its being moved by jarring ot' the machine, so that said ratchets will always be in position to be engaged by one of the hooked lpawls at the completion of either of the cross movements, as will presently be explained.

40 denotes a yoke secured to plate 4, and 47 an oscillating lever pivoted to said bracket. The upper end of this lever is provided with a roller, 4.8, engaging a cam-groove, 49, in a plate, 50, carried by t-he plunger. At the lower end of lever 47 is a spherical roller, 5l, engaging slot 52 in a plate, 523. This plate is journaled on a stud, 54, projecting' upward from plate 4. Below plate is a ratchet, 55, rigidly secured to a disk, 5G, having' ratchetteeth 5U at its edge and provided on its under side with a cam-groove, 57. Below the disk is the reciprocating plate (5, which carries a roller, 58, engaging the cam-groove in the disk.

59 is a boss on plate 4, projecting upward into opening 7, but not engagin said opening', said boss serving as a support for stud 54.

60 is a hooked pawl pivoted to the under side of plate 53, which is adapted to engage ratchet 55 to carry said ratchet and disk 50 forward at each oscillation of plate (i.

6l. is a spring engaging pawl 60 and acting' to hold the hook in engagement with a tooth of the ratchet.

(52 is a spring-actuated pawl which engages the teeth of ratchet 55, actin to hold it against backward movement.

(53 is a spring-aciuated pawl adapted to engage one of the ratchet-teeth in the edge of said disk at the proper instant to lock said disk against being' carried forward too far when actuated by the engagement of hooked pawl (i0 with ratchet 64 is an arm projecting forward from plate 53, which engages the inner side of pawl 63 and acts to lift said pawl. out of engagement with the disk when ratchet 55 is engaged by pawl UO. The function of this pawl. is to lock the disk against bein carried forward too far by the engagement of pawl GO with the ratchet.

lt will be noticed (see Fig. l) that as plate 53' and the arm swing toward the left the arm passes out of engagement with pawl 63, allowing said pawl to drop down and engage one of the teeth of the ratchet to lock it against further forward movement. The return movement of the plate and arm lifts the pawl again out of engagement with the disk, so that it may move forward again when the IOO IIO

plate and pawl move toward the left, all of these movements being' clearly illustrated in Fig. 1. (See, also, Figs. 3 and 5.)

The operation of this portion of the machine is as follows, all of the parts being actuated from the plunger: ln inserting a strip of. metal adjusting-'lever 17 is turned so as to allow springs l5 to lift the upper roller, and the strip of metal is passed forward under the male die. Lever 17 is then turned back again to clamp the upper feed-roller upon the strip. It will ot` course be apparent that the lower feed-roller may be made adjustable, if preferred. The machine is now ready to start. Itis of course preferable to insert the strip of metal when reciprocating plate o' is at one extreme or the other of its movement. This, however, is not essential. Let us suppose that the strip is inserted when reciprocating plate t) is at the extreme ot' its movement toward the back of the machine, as viewed in Fig. 2, this position of the parts being clearly illustrated in Fig. Li. The last downward movement of the plunger has, through the operation of oscillating' lever i7, plate 53, the pawl, ratchet, cam-disk, ttc., as shown in lfig. Il, moved plate and all of the parts carried thereby, including the feed-rollers and the strip of metal, toward the right of the machine, as seen in Fig. atwthat is, toward the front, as seen in Fig` 2-and the last portion of the upward movement has actuated the Afeed-rollers and carried the strip of' metal forward through the engagement of the left hooked pawl 4l, as seen in Fig. 4, with the left ratchet 40. 'lhe result of these lateral. and forward movements of the strip has been to place the strip in such position relatively to the dies that the next downward movement of the plunger will strike out a blank the forward end of which shall be cut 'from metal between the rear ends of the last two blanks struck out. lt will of coursebe apparent from Fig. .1L- that lhe downward movement of the plunger which cuts the first blank after the forward and lateral movements of the strip j ust described will, through the operation of oscillating lever -l7 and the parts operating in connection therewith, carry reciprocating plate t3, plate 22, the feeding mechanism, ttc., far enough toward the right, as seen in Fig. 4, to place the stripin the proper position to receive the next blow of the male die. lt should be noted that this lateral movement of plates and the feeding mechanism, &c., will carry the left ratchet 1t() far enough toward the right so that it will not be engaged by the left hooked pawl 4l when the upward movement of the plunger takes place. It will thus be seen that the feed-rollers, while holdingI the strip of metal firmly at all times, do not act to carry it forward, except when the last blank has been struck out from either edge of the strip, the metal being supplied to the dies by the lateral movement of the strip caused by the reeiprocation of plate o.'

Turning now to Fig. l, I will describe more clearly the operation of the mechanism which actuates plate 6 and carries the strip of metal from left to right, and vice versa. As already stated, the position of the parts in Figs. L and l, corresponds, the plunger being at the raised position. It maybe added, furthermore, that the parts are in same position in Figs. 2, S, and 5, the lower en d of lever 47 being swung toward the left, as viewed from the front. The downward movement of the plunger through the engagement of roller 4:8 with cam-groove -lfl swings the oscillating lever and plate 53 toward the right. Asthe plate swings around, hooked pawl (30, carried thereby, is moved around also, carrying ratchet 55 and disk 56 with it. This movement of the disk imparts a movement to plate (i through .the engagement of rollers 5S, carried thereby, with the cam-groove. These movements continue until the feed-rollers and the strip have been. carried to their extreme position toward the right, as seen in Fig. -lthat is, the reverse of the position shown in said ligure. This will place the Aright hooked pawl -Ll-l in engagement with the right ratchet 4D, so that after the last blank has been struck out from the strip on the right side the upward movement of the plunger will cause the forward movement of the feed-rollers, and at the same time oscillating lever 4:7 and the parts acting' in connection therewith will impart the usual lateral movement to the strip. This will place the strip in such position relatively to the dies that the next blow of the male die will strike out the iirst blank from the next series, the forward portion of which, as usual, vis cut from metal left between the rear ends of the last two blanks struck out. In order that this maybe clearly understood, attention is called to Fig. l0, which is a diagram illustrating the manner in which the blanks are cut from the strip of metal, and to Fig. U, which is an inverted plan view of disk 5G, showin the camgroove in the under side thereof. The strip shown in the present instance is of sufficient width to produce the wide ends of four blanks of the style shown and also the narrow ends of 'four other blanks which are cut fromA between the wide ends of the row last cut. It is ot' course understood that in this class of work the great desideratum is to produce as many blanks as possible from the strip of metal Vfed to thc machine, so that the quantity of scrap shall be' reduced to the minimum.` An independent opening is left in the strip of metal where each blank is cut out, as it is necessary that each blank be cut from solid metal.

For convenience. l have designated the first four blanks cut vfrom the strip of metal as it moves from left to right in Fig. -l--that is, 'from the extreme of its movement toward the back, as seen in Fig. l-tmvard the front as, respectively, n, l), c, and d. rlhe upward movement of the plunger after blank d has been cut out causes the lirst forward movement ot the strip referred to, and the next downward movement produces the firstof the, reverse lateral movements, the two move- IOO IIO

lZO

ments acting to place the strip in position for blank e to be cut out, which is the Iirst blank of the return series as the strip moves from the reverse of the position shown in Figs. 1 and 4 toward the position shown in said figures. rlhe next three blanks are denoted by j', g, and h, it being' understood that the forward portions of blanks e, j', g, and h are cut from solid metal left between the rear portions of 1o blanks c, b, c, and d. The next upward and downward movements of the plunger after the blank 71. has been cut produce the second forward movement of the strip referred to, accompanied by a lateral movement, which places the strip in position relati\'fely to the dies for another blank, a, to be cut, these movements being continuously repeated as long as the strip holds out. The scrap left after cutting out the blanks is ordinarily 2o melted over. lt is, however, quite bulky and requires to be cut up into small pieces before going to the melting-pot. In order to avoid the additional operation of cutting' up by the user, and also for the convenience of the 2 5 maker of the scrap in packing it, I provide a scrap-cutter which operates in connection with the plunger and feeding' mechanism to cut the scrap up into small pieces.

65 is a bracket depending from one of the 3o arms 43, to which the upper cutter, 6G, is attached.

67 denotes the lower cutter, which is secured to an angle-plate, (38, which in turn is rigidly secured to the bed of the press. Upon the top of the angle-plate is a block, (it), to which a holding-bar, 70, is secured. The scrap as it is fed forward by the feeding mechanism, having' passed the dies, acted upon by the cutters at each movement, the strip of scrap 4o passing' under the holding-bar, by which it is held against displacement. As the strip moves across the bed in the latei'al feeding' movements, the cutters of course do not act upon it; but after each forward movement the next downward movement of the upper cutter cuts a length from the end of the strip of scrap equal to the amount of metal that was fed forward.

The cutters are ordinarily so located rela- 5o tively to the dies as to cut the strip oi' scrap midway of the openings whcre the blanks are cut out-as, for inst-ance, at or about the line 'where the letters a, l), c, and d are placed at the right in Fig. 10-so that the scrap is re- 5 5 duced to small pieces.

It Will of course be understood that the details of construction may be varied within reasonable limits without departing from the spirit of my invention.
