To all whom, it may concern/.

Beit known that 1, WILLIAM J. GORDON, a

citizen of the United States, residing in the city and county of Philadelphia; State of Pennsylvania,'have invented a new and useful Improvement in Combination Triple-Die Presses, which improvement is fully set forth in the following specification and accompanying drawings. I

My invention relates to improvements in combination triple-die presses; and it consists in so locating the punches relatively to each other, and which inthe present instance are three in number, that if a line be drawn from the center of one of said punches and through the centers of the other two, and then back to the center of the original punch, said line will describe a triangle.

It also consists of means whereby the sleeves to which the punches are secured may be brought nearer to or farther from each other, according to requirements.

It also consists of novel means for adjusting the punches in order to compensate for the wear of the same, which mayoccur from long use, grinding, the. Y

It also consists of novel means for adjusting the rotation of the feed-rollers in order that the latter may cause the proper length of metal to be fed to the punches in a given time.

It also consists of novel means whereby sets v of dies of various sizes may be employed and the same placed in alinement with punches of a corresponding size.

It also consists of'means whereby one pair of feed-rollers may be moved nearer to or farther from the dies, accordingto requirements.

It also consists of novel means for retaining the dies and punches in position.

It also consists of novel means whereby a sheet of metal to be punched, after being placed in a guide which guides said sheet to the feed-rollers, is retained in said guide and prevented from reaching the feed-rollers untilthe proper time arrives, when the sheet is automatically released and is permitted to reach the feed-rollers.

It also consists of a novel construction of a cross-head and also of abed in which the same reciprocates.

It further consists of novel details of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Similar characters of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates the frame of the machine, in which is journaled the shaft 2, the latter having the cams 3, the crank 4, and clutch member formed therewith, it being evident that, if desired, said parts may be secured to the shaft 2 instead of being integral therewith, if so desired. (See more particularly Figs. 1 and 20.)

6 designates a driving-wheel loosely mounted on the shaft 2 and provided with a clutch member 7, which latter is adjacent to the member 5,-so that said members 5 and 7 may be caused to either interlock or else be separated, according to requirements. The driving-wheel 6 is driven by a belt in the usual manner. The clutch member 5 is provided with a bolt 8, against which bears a spring 9.

. (See Fig. 1.)

1O designates a rock-arm fulcrumed to the frame 1, as at 11, (see more particularly Fig. 3,) said arm serving as a deflector for the bolt 8, as will be hereinafter described.

12 designates a link, one end of which is secured to the arm 10, the other end of said link being secured to a lever 13, which latter is in the present instance operated by foot and for a purpose to be hereinafter described. The lever 13 has connected therewith one end of a spring 14, the other end of said spring being secured to the frame 1, so that said spring 14 normally retains the lever 13 and its adjuncts in the positions seen in Figs. 1 and 3.

The frame 1 is formed with grooves or Ways Fig. 35 represents a horizontal sec-.

15, (see Fig. 18,) said grooves 15 being adapted to receive the tongues 16, which project from the slide or cross-head 17, as best seen in Figs. 10, 11, 12, and 13, it being evident that said tongues and grooves will prevent even the slightest lateral displacement of said cross-head 17. The cross-head 17 is retained in position in the frame 1 by the gibs 18. The cross-head 17 is provided with rollers 19,which contact with the cams 3 for a purpose to be hereinafter described. The cross-head 17 has secured thereto the rods 20, (see Fig. 2,) which pass through lugs 21 on the frame 1 and are encircled by springs 22, the lower ends of which bear against said lugs, while their opposite ends bear against sleeves 23, which inclose said springs and are retained in position by nuts 24. The springs 22 return thecross-head 17 to its normal position, as seen in Fig. 1, after the same has been depressed by the cams 3. The slide or cross-head 17 is formed with recesses 25, (see Figs. 1, 10, and 12, said recesses being adapted to receive the sleeves 26, one of which is illustrated in detail in Figs. 34 and 35, it being noted that when said sleeves are placed within the re= cesses 25 they are retained therein by the

caps

28 and 29. The sleeves 26 are provided with screw-threaded studs 30, on which are fitted nuts 31, which assist in retaining said punches in position within the cross-head 17. The slide or cross-head 17 is provided with slots 32, (see Figs. 1, 2, 12, and 13,) it being noted that the studs 30 are passed through said slots 32 in order to permit the sleeves 26 to be either raised or lowered, according to requirements, it being understood that the cap 29 is provided with slots similar to the slots 32. (Seen in Figs. 1, 2, 12, and 13.)

33 designates an adjusting-plate which is interposed, when required, between'a sleeve 26 and the slide or cross-head 17, as best seen in Fig. 1 and for a purpose to be hereinafter described, it being noted that said plate is formed with recesses 34, through which the studs 30 are passed, it being apparent that said recesses permit a sleeve to be either raised or lowered while said plate may remain stationary.

35 designates a pitman, one end of which is fitted on the crank 4, its other end being pivoted to a triangular knuckle-yoke 36, in which are secured the plungers 37, which are preferably arranged in triangular order, whereby space is economized, waste of the material to be punched is reduced to a minimum, and the output of the machine is greatly increased, as best seen in Figs. 24, 25, and 26. (See also Figs. 1 and 2.) The triangular knuckle-yoke 36 is provided with slots 38, in which are placed the nuts 39, it being noted that the threaded portions of the plungers 37 are fitted into said nuts in order to firmly secure said plungers to said yoke 36, it being apparent that said slots 38 permit the plungers 37 to be located nearer to or fartherfrom each other, according to requirements and for a purpose to be hereinafter described. The plungers 37 are located within chamber 41 of the sleeves 26, which carry the punches 46, so as to be raised and lowered therein, for a purpose to be hereinafter described. (See more particularly Figs. 34 and 35.) The sleeves 26 are provided with adj Listing-nuts 42 and 43 and the

washers

44 and 44, said nuts serving to firmlysecure the sleeves 26 to the slide 17, so as to cause the sleeves to move in unison with said cross-head, said nuts permitting the adjustability of the punches 46. Each sleeve 26 is provided with a screwthreaded coupling-sleeve 45, in which is fitted the punch 46. The washers 44 are provided with slots 46, which latter receive the pins 47, which depend from the cap 28. (See Figs. 17, 32, 34, and The object of the slots 46 and pins 47 is to prevent the washers 44 from turning when the nuts 43 are either tightened against the same or else slackened therefrom and for a purpose to be hereinafter described. The cap 28 is provided with a projecting arm 48, in whose outer extremity is fitted an adjustable bolt 49, (see Figs. 1, 2, and 19,) said bolt being retained in adjusted position by one or more lock-nuts 50.

51 designates a guide adapted to be secured to the frame 1 of the press, as best seen in Fig. 2, (see also Figs. 7 and 8,) it being noted that the guide-rails 52 of said guide are provided with slots 55, through which the bolts which secure said guide to the frame 1 are passed, it being apparent that said slots 53 permit the rails 52 of said guide to be brought either closer together or else moved farther apart, according to requirements and for a purpose hereinafter referred to. The braces or cross-bars 54 of the guide 51 are provided with slots 55, through which are passed the bolts 56, the latter serving to retain the guide-rails 52 in adjusted position, it being noted that said bolts 56 are screwed into said rails 52, as best seen in Fig. 8. It will be apparent that the slots 55 permit the guide-rails 52 to be moved either nearer to or farther from each other, according to requirements and for a purpose to be hereinafter described. The guide-rails 52 are formed with depressed portions 56, which serve as ways for the sheet metal to be punched to rest upon, it being apparent that the walls 57 prevent a sheet 58 of metal from lateral displacement when placed in said ways. The guide 51 is provided with a rockshaft 59, which is journaled in posts 60, secured to the members 52 of the slide 51, it being noted that said rock-shaft has firmly secured thereto the

fingers

60 and 61, the object of which will be hereinafter described. The rock-shaft 59 and its adjuncts are retained in their normal positions, as seen in Fig. 2, by an arm 62 and spring 63. 1 (Best seen in Figs. 7 and 19.) The guide 51 has secured thereto a stripper-plate 64, which strips a sheet 58 from the punches 46 when thelatter are being withdrawn from said sheet after a set of blanks have been punched, it being noted that said stripper-plate is provided with openings 65, through which the punches 46 pass.

The shaft 2 has secured thereon a disk 66, (see Figs. 1, 4, and 5,) it being noted that said disk is provided with a graduated scale 67 and a slot 68, in which latter is fitted an adjustable wrist-pin 69, which may be moved nearer to or farther from the axis of the shaft 2 by means of the bolt 70, which is swiveled to said wrist-pin, it being noted that said wrist-pin 69 has connected therewith one extremity of'a link 71, the opposite extremity of which is connected to an arm 72, which latterprojects from a clutch member 7 3,whose inner portion is provided with eccentric working faces 74 (see more particularly Fig. 29) and an outer rim 75, which latter fits snugly against the rim 76 of the clutch member 77, secured to the gear-wheel 78, it being noted that rollers 79 are interposed between the working faces 74 of the clutch members 73 and the rim 76 of the clutch member 77 and that said rollers are retained in their normal positions, as seen in Fig. 29, by springs 80. The gear-wheel 78 is journaled in the frame 1 and meshes with a pinon 81, secured to the shaft portion 82 of a feed-roller 83, journaled in boxes 83 bolted in the frame 1. (See Figs. 1, 2, 4, and The shaft portion 82 has secured thereon a pinion 84 and gear-wheel 85, it being noted that the pinion 8t meshes with a pinion 86, secured to the shaft portion 87 of a feed-roller 88, journaled in the frame 1. The gear-wheel meshes with an idler 89, journaled in quadrant 90, fulcrumed on the shaft portion 82, as best seen in Figs. 4 and 5. The quadrant 90 may be turned on its fulcrum for a purpose to be hereinafter described, it being noted that said quadrant is provided with a slot 91, through which is passed a bolt 92 for securing said arm in its adjusted position. The idler 89,which meshes with the gear-wheel 85, meshes also with a gear-wheel 94, which latter is secured to the shaft portion 95 of the feed-roller96,it being noted that the extremities of said roller 96 are journaled in boxes 97 in the frame 1. The shaft portion of the roller 96 has secured thereto a pinion 98, which meshes with a pinion 99, secured to the shaft portion 100 of the feed-roller 101. The jourrial-boxes 97 are provided with slots 102, (see more particularly Fig. 6,) it being apparent that said slots permit the boxes 97 to be placed nearer to or farther from the boxes 83 for a purpose to be hereinafter described. The boxes 97 are secured in adjusted position by bolts 103.

104 designates a bracket secured to the frame 1 and provided with a bolt 105, which latter is retained in adjusted position by nuts 106 and 107, and the object of said boltwill be hereinafter described. In practice two brackets 104 are employed, although but one of these is illustrated in the drawings, the

one that is not shown being bolted to the portion 108 of the frame 1. (See Fig. 1.)

' byto the punches 46.

The wrist-pin 69 is provided with a pointer or index 109, employed in connection with the graduated scale 67. (See Fig. 4.)

' The operation is as follows: Motion is imparted to the pulley 6 in the presentinstance bya bolt 110, (seen in Fig. 1,) the clutch memher 7 rotating with said pulley 6. When it is desired to put the press in motion, the lever 13 is depressed, thereby causing a portion of the rock-arm 10 to rise in order to be moved out of the path of the bolt 8, which latter, no longer meeting with the resistance presented by said rock-arm, is moved forward by the spring 9 and caused to engage the clutch member 7, whereby motion from the pulley 6 is transmitted to the shaft 2, cams 3, and crank 4thereon. Asheet 58 of metal is then placed in the slide 51 and descends by gravity to the fingers 61, against which it abuts and is temporarily prevented from further descent. The cams'3 now cause the cross-head 17 to descend, as likewise the punches secured thereto. At the proper time the bolt 49 is broughtin contact with the finger and depresses the same, thereby turning the rock-shaft 59 and causing the fingers 61 to rise in order to release the sheet 58 of metal, which then continues to descend until it reaches the feedrollers 96 and 101, so as to be drawn between them in order to be fed thereby to the punches 46. The rotation of the shaft 2 transmit-s a similar motion to the disk 66, which in turn imparts motion to the link 71, thereby rocking the arm 72 and causing the same to impart a partial rotation to the clutch member 73 in the directionindicated by the arrow at in Fig. 29, thereby causing the Working faces 74 to jam the rollers 79 against the rim 76 and cause the latter to move in unison with said clutch member 73, and consequently impart motion to the gear-wheel 78, which latter will, as is evident, set the entire train of gearing seen in Fig. 4 in motion in order to rotate the feed-

rollers

83, 88, 96, and 101, so that the same will cause the sheet 58 of metal to be drawn between them in order to be fed there- The rotary motion imparted to the feed-rollers hereinbefore described is an intermittent one. When a sheet 58 has been brought in the proper position relatively to the punches 46 by said feed-rollers, said punches are moved downwardly by the action of the cams 3 on the cross-head 17 and are forced through the sheet 58, thereby cutting blanks therefrom and causing the same to rest on the rims 110 in the dies 111, as best seen in dotted lines, as at 112, in Fig. 22. The plungers 37 are now lowered by the crank 4 and pitman 35 and force the blanks through the openings 113 in the rims 110, thereby producing a flange or rim 114 in the blank, as seen in Fig. 23. After the blanks have been cut and the flanges or rims formed thereon, as hereinbefore described, the punches 46 and plungers 37 are raised, the former by the spring-actuated rods 20 and the latter by the crank 4.

The finished articles, similar to those seen in Fig. 23, drop through the openings 115 (seen in Fig. 1)'and may fall into a receptacle of any suitable description. It is to be noted that when the disk 66 is revolving in the direction indicated by the arrow 1) in Fig. 4 and the wrist-pin 69 is moving from c to (1 said disk will exert a pull upon the link 71 and cause the same to impart a partial rotation to gear-wheel 78 by the clutch mechanism hereinbefore described in connection with Fig. 29 and cause said gear-wheel 78 to revolve in the direction indicated by the arrow 6 in Fig. 4. When, however, the wrist-pin 69 is traveling from d to c, the disk 66 will exert a push upon the link 71 and cause the latter to depress the arm 72, thereby causing the clutch member 73 to move freely on the clutch member 76, and thus impart no motion to the latter until the link 71 is again raised by the rotation of the disk 66. The intermittent rotary motion imparted to the clutch member 76 will be transmitted to the gearwheel 78, which in turn will imparta simiiar motion to the train of gearing seen in Figs. 4 and 5 and cause the several gear-wheels and pinions to turn in the direction indicated bythe arrows in said figures, thereby causing the feed-rollers hereinbefore described to impart an intermittent feed to a sheet 58, so as to advance the same the proper distance after each punching and rim-forming operation. hen it is desired to stop the press, the operator removes his foot from the lever 13, whereupon the spring 14 restores said lever to its original or normal position, (seen in Figs. 1 and 2,) thus causingthe lever 10 to again occupy a position in the path of the bolt 8, whereupon the latter will be brought in contact with the flaring face 10 of the lever 10 and be caused to move in the present instance to the left, (see Fig. 1,) and thereby be removed from engagement with the clutch member 7, whereupon the shaft 2 and its adjuncts,as well as all other parts receiving motion therefrom, will come to a stop, it being understood that the operator keeps the lever 13 depressed as long as the press is to be kept in operation.

WVhen the smallest'size of punches and dies are employed, the punches are in the position indicated by dotted lines at e in Fig. 24, and the dies seen in Fig. 38 are in alinement with the same, it being understood that said dies are fitted into a plate 115 (seen in Figs. 22 and 38,) said plate being bolted or otherwise secured in the bed 116 of the press. (See Figs. 1 and 2.)

117 (see Fig. 22) designates a plate secured to the plate 115 in order that its upper face 118 may be flush with those portions of the dies 111 which project above the plate 115 so as to cause a sheet 58 to rest snugly upon said dies.

When it is desired to employ a larger size of punches and dies, the plate 33, (seen in Fig. 1,) similar in construction but of greater IIO thickness than the plate 33, (seen in Figs. 14 and 15,) is removed from the press after slackening the nuts 31 on the studs 30, and another plate, similar in construction to the plate 33, but of less thickness, is inserted in the space formerly occupied by the plate 33, whereupon the sleeves 26 may be moved farther apart, it being understood that said sleeves are three in number, and the remarks made relatively to one of these apply to all. hen the sleeves 26 are moved farther apart, it becomes necessary to remove the smaller cutting members or punches 46, one of which is seen in Fig. 37, from said sleeves, and other cutting members similar in construction to the one seen in said Fig. 37, but of larger diameter, are inserted in the sleeves 26.

When the cutting members or punches 46 are of a certain increased diameterfor in stance, as indicated by dotted lines atfin Fig. 24it is to be understood that the sleeves 26 are in their extreme outward position in the cross-head 17, in which case no plate such, for instance, as that seen in Fig. 1 and bearingthenumeral of reference 33' is employed, as the sleeves are drawn tightly against the outer walls of the recesses 25 by tightening the nuts 31.

It will be noted on referring to Figs. 1 and 10 that the recesses 25 are of greater length in a horizontal direction than the thickness of the sleeves 26, thus permitting the latter to be moved either toward or away from each other, according to the diameter of the cutting members or punches 46.

The slots 38 in the triangular knuckle-yoke 36 permit the plungers 37 to be moved either toward or away from each" other to correspond with the several adjustments of the sleeves 26, within which the same are placed and caused to reciprocate by the crank 4, as hereinbefore described, it being apparent that in order to shift the plungers 37 it will be necessary to first slacken the nuts 39, which is accomplished by rotating said plungers,which are provided with the angular portions 37, to which a wrench may be applied for the purpose. In Fig. 25 the plunger 37, to the right, is shown in the position it occupies when the sleeves 26 are in the positions indicated in dotted lines at e in Fig. 24, and when the sleeves 26 are in the positions seen atfin Fig. 24 the plungers 37 are in the positions seen to the left in Fig. 25.

The sleeves 26 may be either raised or lowered in the cross-head 17 for the purpose of adjustment by the manipulation of the nuts 42 and 43, which secure said punches to the cross-head 17.

The pins 47, (seen in Fig. 17,) which enter the slots 46 in the washers 44, (seen in Figs. 32, 34, and 35,) prevent said washers from turning when the nuts 43 are rotated, and, furthermore, permit said washers to be moved in unison with the punches 26 when these latter are moved either toward or away from each other for the purpose hereinbefore described.

When the dies 111 of the type illustrated in Fig. 38 are to be placed in the press, the plate 115 in which said dies are secured, is bolted to the bed 116 of the press, and when blanks ot'extralarge size are to be punched and flanged dies 117 of the type illustrated in Fig. 39 are employed, said dies being bolted directly to the bed 116 of the press, it. being understood that said dies 117 are three in number and are secured in position in the press independently of each other, and not three at one time, as in the case of the dies 111. (Seen in Fig. 38.) Assuming that when the several parts seen in Fig. 4 are in their adjusted positions relatively to dies 111 of the diameter seen in Fig. 38, it is to be understood that should dies of larger diameter be required it then becomes necessary to remove said dies from the press and replace them by ones of larger diameter. This will necessitate the wrist-pin 69 being'moved farther from the axis of the disk 66, which will, as is evident, impart a greater throw to the link 7]., and consequently impart a greater degree of revolution to the train of gearing seen in Fig. 4, thus causing the feed-rollers hereinbefore described to increase the amount of feed imparted by the same to a sheet 58.

As it is of the greatest importance that a sheet 58 should be presented to the punches at the proper time, it becomes necessary that the feed-

rollers

96 and 101 should be movedv farther from said punches, so as to compensate for the increase in the amount of feed imparted to a sheet 58. In order to accomplish this end, the nuts 92 and 103 are slackened, whereupon the journal-boxes 97 may be moved away from the punches 46, whereupon the gear-wheel 94 will leave the idler 89, and in order to cause said idler to again mesh with the gear-wheel 94 the quadrant 90 is turned upon its axis, so as to cause the gearwheel 89 to mesh with said gear-wheel 94, after which the nut 92 is tightened, so as to retain said quadrant in its adjusted position.

The bolt 105 may be employed as a gage against which the journal-boxes 97 abut when said bolt has been adjusted relatively to a punch and die of a predetermined size.

119 designates an arm loosely mounted on the axis 120 of the gear-wheel 78, (seen in Figs. 41, 43, and 44,) said arm 119 having journaled thereon a pinion 12l,which meshes with the gear-wheel 78, it being noted that the pinion 121 engages also with a check-pawl 122, pivoted to the arm 119, said check-pawl 122 being held against the teeth of the pinion 121 by a spring 123. when the rod 71 (seen in Figs. 41, 43, and 44) is moving in the direction indicated by the arrow 'm in Fig. 41 the arm 119 will be caused to move in the direction indicated by the arrow n, whereupon the pinion 121 will be rotated in the direction indicated by the arrow 19 by reason of its engagement with the gearwheel 7 8, which latter during the downward stroke of the rod 71 remains stationary.

It will be apparent that Ioo When the rod 71 is moving in the direction indicated by the arrow 0' in Fig. 43, the arm 119 will be caused to move in the direction indicated by the arrow 8, it being noted that the check-pawl122 is engaged with a toothin the pinion 121 in such a manner that said pinion cannot rotate when the rod 71 is moving in the direction indicated by the arrow 8, whereupon it will be apparent that said pinion 121 acts substantially as a dog relatively to the gear-wheel '78, and will consequently rotate the latter in the direction indicated by the arrow t in Fig. 43, and the gearwheel 78 will then impart motion to the train of gearing hereinbefore referred to, and thus transmit motion to the feed-

rollers

83, 88, 96, and 101 for the purpose hereinbefore described.

In Fig. 45 the arm 121, which corresponds to the arm 119, (seen in Figs. 41 to 44, inclusive,) is provided with a plurality of checkpawls 125, which corresponds to the pawl 122, (seen in Fig. B,) it being apparent that when Several pawls are employed an exceedinglyfine adjustment of feed may be imparted to the

rollers

83, 88, 96, and 101.

It will be apparent that changes may be made by those skilled in the art which may come within the scope of my invention, and I do not therefore desire to be limited in every instance to the exact construction Ihave here in shown and described.
