The present invention permits of meeting these inherent difficulties so that multiple points of pressure connection may be secured whereby less massive operating parts may be used andalso long and satisfactory guides are attained Without the necessity for widening or deepening the press frame, thus avoiding the use of more oor space and also avoiding any objectionable increase in weight of the press. Thus a very effective and efficient construction is attained which gives inherent operating advantages land -with a comparatively large slide approaching lor approximating in size the press bed portion-which is especially advantageous for certain operations,

e. g., piercing, blanking and trimming.

These and other advantages are attained by the present invention ofwhich a preferred embodiment isshown infthe drawings. l

In such preferred embodimentthepress frame is designated generally by 'the reference character `2f). It is. shown` as'an` integral casting formed to provide a bed portion 22 and a portion `24 overhanging bed portion 22 and substantially narrower than said bed, said .portions being connected by side members 23...;.The slide member, for carrying .the movable die,.is designated generally by the reference character 25 and is mounted for reciprocal movement in the gap 26 between frame portions 22 and 24. A bolster plate 2l is bolted, or otherwise secured in usual manner, to bed 22 vanclprov'lded with suitable means, such as usual bolt receivers, forffastening a lower die thereto. Framel 20 ,is pivotally supported by means ofxpins 28, which pass through the side-frames 23V and into a base which cornl prises two upright members 3B secured to gether by means of aplurality of tierods 32, shown as held in place'by nuts, the base thus being made into a suitably strong and rigid structure. As shown forexample in Fig. 2, the .pins 28 are mounted in enlarged or reinforced `portions 33 [carried by base members 30 and held in, place by means vof locking bolts 34. Near the bottom and rear offramez eachside-irame has a plurality of holes, arrangedgenerally in an arc having itscenter in the. axiszof the pivot pins 28, these holesbelng formed in a reenforced r arcuate shaped boss portion .35. .Each of these -.holes 36 is adapted-to receive a bolt, 38, which may be mounted in oneoranother ofthe holes..

Each base member.30,-isalsoprovidedwith a hole or passage 3'! each located to be. registrable with one of the cooperatingsetof holes or passages 36. By positioning the pins ,or bolts 38 in alignedfpassages 36 and 3T the frame 25 may be locked in any selected oneof a plurality of positions about pivotK-pins 28.three such selective positions being illustrated and the holes 36 and 3l being sov positioned relatively that the frame 2|),may be positionedupright or in two different inclined positions.

Y Referring to Figs. 1, 3, 'l and 10, for example, means is illustrated for effecting rocking motion of frame 2G about pivot pins 28. Such means comprises a rod 40 which is pivotally secured at its upper end to a pvot pin 42 carried by boss 43 on frame 20. This rod is hollowv throughout its greater extent andatgthe opposite end the wall is thickened and threaded for engagement with the threaded rod 44one lend of which is,

screwed therethrough to extend intothe hollow passage within the rod 4U., A gear45 vis operas tively secured to the lower end of rod 44. As shown, this lower end has its extreme lower end portion 45 of somewhat larger diameter than the threaded part of the rod and the end por tion 46 which receives the gear 45 and thus provides a shoulder against Vwhich the gear 45 abuts when it is slipped over the inclined screw or ro.. 44 before assembly of this inclining or positioning mechanism. The hub of the gear 45 has an internal longitudinal keyway cut therein, and

the part 4B has a longitudinal key receiving pocket which receives the key 46, this arrangement permitting ready assembly of' the gear 45 on the part 4B so that it may seat against the shoulder yformed by part 48 and thus automatically move to properly adjusted position on the rod 44 as these parts are assembled. The enlarged portion 46' seats rotatably in a passage in the member 4l which is pivotally connected at one end to a receiving lug or enlargement 48, carried by one ofthe sideA members 3U, by pivot pin 48. Preferably a grease member or gasket is interposed between the rod portion 46 and the bottom of thefpassage in which itis rotatably mounted, to facilitate maintaining easy rotatable operation of the screw 44.

VThe other end of the member 41 is enlarged to form a part 4l' which is one part of a housing for the gear 45 and its operatingmechanisrn. Co-v operating with housing part 4l is another housing part 4l, the two parts being held in assembled position by bolts 49 to form a securely engaged and tight housing. Each of the parts 4l-4`l" is provided also with aligned passages 50 which together form receiving and bearing passages into which opposite ends of the shaft 5l are rotatably positioned., This shaft5i car rises a worm pinion 52 formed integrally with the shaft 5 I, or otherwise held in place thereon, which pinion meshes with the worm gear 45. As shown each of the parts 4l-4l, is formed with an enlarged space, the two spaces together forming an internal housing space 53 for thevpinion 52, when. these parts are in assembled relation. Spaced collars or flanges 53 are carried by the shaft` 5| and seat against suitable gaskets or washers 54, which in turnY rest'againstthe inside wall of the parts 4- 4l" to Vhold the worm in proper adjustment with respect to vthe gear 45, to permit ready turning o f the shaft 5I for the operation of the gears 45-52, to absorb the operating forces and to prevent ingress of dirt into and of grease out from the gear vhousing chambers. The inner face of the part 4l serves as a bearing face against which the gear 45 is ro,- tated,'the other partA 4l having an inturned flange 55 which forms a borereceiving the collar of the gear 45 and which rests against the opposite face of gear 45, when the parts ai'e assembled. With the parts 41-4l" tightly bolted together with the gears in position as described, the gear 45 is thus held rotatably between the cooperating face of the part 4l and the flange 55; and the gear 45 being keyed to the rod 44 to permit relative axial movement of the gear upon this rod or screw, whilethetwo vare constrained to rotate together, assembly of these parts andv pulling Ythe parts 41'-41 tightly together by the bolts will cause the gear 45 to seat against the abutment shoulder vformed by the enlarged portion 4-6 and to be held with proper rotating clearance between the flange 55 and the bearing face of the member 41. One end of theshaft 5l: extendsoutside the housing :and has provisions, such as a squared end 56, to receive a driving inem'ber;` or-crank, to rotate the worm 5'2fandiwith itffthegear K5. When' such rotation `is tofbeeffected, the pins or bolts-'tirareremoved, 4and such Irotation will cause the threaded portion of the bo1t1ltlltoA rotate i relative to the none-rotatablelportionvll thereby to causesaidfrodstomove telescopically with-respect toeac-h'other and ythus to l`increase or decreasethe distance-between'pivot Mandlpivotdt. llhustheframe ZLmay be readilly swungor' rocked vabout pins 28, and when Ait is in the desired upright or inclined position -it maybelo'cked in such position by inserting the bolts 381' in theholes 3l and the ones of? the -holes onix passages 36 which have 'been brought" into aiignment.- Preferably nuts are provided for the insidedends' of the vbolts -38 to fhold"` them* 4.against displacement during operation of-thef press;

Asstated, the press structureillustrated is of the open-back. type, and the open-back of the frame: 29;. above `the bed` portion-beingV indicated by: the numeral 59, the back 'part of: this frame Iikewisebeing open below the bedrv portion, as indicated byv-the numeral 5B". Thisv permits of gravity dischargelwhen the-frame is inclined, and offfreedischarge ofparts at the rear of the press,

in anytposition thereof. A

Frame portion' 2.4, which isI atf-r the upper end and'oyerhangs the bed portion 2.2, carries a pair ofialigned shaft membersv Si?, oneat'eachside;

`Eiach'ioil these members is shownwas having one end mounted in a passage in the. frame, which isfreenforced. by .enlarged portionr E2 'tojgive the necessary: strength. factor. Eachr shaft i member hasione end heldin its passage by locking member 3..and V.the othery end extending outwardly triomf the frame to support rotatably agear 65 andianeceentric 66. As shown, each-drivefgear GSi-.and its-eccentric are integral, each being aixed to a common hub 6l xwhereby one drive gear-eccentric. unitary member' is rotatably mounted; on theprojecting end of one shaft B0 and; the other` on the end of the other'of these shafts... The hub 61 ofthe unitary` drive geareeoentricrmember is provided with 1a suitable bearing:L or: bearingv surface indicated at 4B8; and. the outerfendof each .hub ..61 carriesacover plate `ESL-which is attached to the .hub/by means of stud-:bolts .or the like, Aand which serves to. retain grease and'to prevent the ingress oi' dirt.

:Each of the eccentrics carries aneoc'entric strap 10;'.which in turn carries a depending link member 1i, lthe lower end of whichextends between the bifurcatedupper end 12of a lower` link member 13A, the two'power transmitting link mem-- bersebeing'. pivotally connected by means of a pivot or wrist pin l5. `Each of the lower link members 'i3 vhasits lower portion it formed yas an:A adjusting. screw,` each* adjusting screw beingthreadedly mounted in an adjusting nut 80, which in turn is rotatably mounted in airecev-inghoiising Si, withinthe die slide 25, lthis adjusting. nut-.being held placeby-meansof an apertured. cover plate 83, which is bolted or otherwise `secured to the die .-slide..'y The innerfiaeeof. the-cover platef83 engages thexadjusting 'nut' 130 and the eover-frneniber '28% Ais i'rm'ly 'bolted orlotherwise secured to the die slide the slide "is thuscaused to `re'ciprooate,in workioperations, upon rotation Aof the drivegear '65, `the eccentric and` link arran'gement transforming rotary Arnotion into reciprocatory 'motion-of the slide. 'O'f course, thec'over members 83 must be bolted for yotherwise secured 'to the die slide 'member so as .to withstand `all of .thezforces incidentxto the4 upward movement of slide;

"shown, `thexpiaess isprovided to have. two pointsi'of. operating power yor. pressure 'application-to. the; movable die slide, the two links' 13 whicharefad'justablyv connected to the die `slide 'beinigconnected 4adjacent its .side edges and ap- -preximatelyi.midway from-the front to the rear. ltfrwill also'ibe noted thatfthe movable die slide f iras such widthlthat it. extendsv laterally on both 'sidesbeyond thefoutsidetof the yside frame members 23, and the. oVer-all-width of the die 'sl-ide., asshownifor. example in Fig. 2, closely approximates theiover-'all width of the bed 22 and the -bolster .plate 2l carriedthereby.

By means of such two point pressure connectionsthe operatingpressures are transmitted to the movable die slide adjacent the side edges, and.A as a resultthe normal operating pressures exerted. bythe press-mechanism and any unbalanced pressures due to unusually shaped dies or other factors known toI give substantial unbalanced `forces arey more readily ycompensated .for,.especially with the form of slide construction utilizedin this embodiment of `the invention. .A movable die slide and movable. die of a greater.' width may therefore be safely used for operating conditionswhich could not readily be met by a single pressure connection, arranged centrally :of the width ofthe ydie as well as centrally fore and aft, and operating conditions can be! readily met in anxentirely satisfactory manner. with effective and efficient operation with such twopoint pressure. connection which would prove insuperable diiculties for a single point pressure yof the samesi'ze and weight.

By the construction shown herein effective and efficient-operation under heavy pressuresis furthergreatly addedito `by the form of slide and the-guiding means which are effective as between thesslide. and the press frame. And thus eiective and efficient operations can be readily attained using parts which are of considerably lighter.` weight by comparison with the conventional. inclinable press; and likewise die slides which. are ofl widthV approximating the width 'of thebed, awidthconsiderably in excess of that normally usedon .conventional inclinable.' presses, can be used quite satisfactorily. The slide member. 25V includes an .elongated upper portion which is designated generally by thev numeral 84 anda laterallylextending die receiving portion which is designated by the numeral 35, this die receiving portion 85 being shown asprovided with a-slide capy 66, and a depending. flange toreceiveand assistin supporting the upper die member. As

shown, the upwardly extending portion. 84 is of gatedbearing'surfaces .adapted for sliding and guiding engagementwith guidemembers carricd.v by the: side walls 231er the frame 2li. As shown;y .for'example'inliig 4', .the guide members $951l eachxcomprises afgenerally L-shaped memberv .orgib which is bolted to an inward facey of its side frame membcr;23, the lparts being properly machinedto t accurately, andthe `back ofthe gib member being provided with a projecting rib which fits into a corresponding groove formed in the face of the framemernber 2?. This construction is suchvthat with .the;,members 95 tightly bolted in place and with their guiding faces vcooperating with theportions 92 and 94 of the slide, quite extended or elongated guides are provided against lateral or tilting movement ofthe slide and also against backward or tilting movement thereof. Each memberil of the slide also has a guide member gbolted to it which member projects to provide a guide face for contact with the face. of its cooperating guide element S5 opposite to the guiding contact of the member 95 with the lateral extension 92. For easier manufacture and assembly and disassembly these members 9S are made separate from and are bolted to the projections 9d, and when properly assembled to have guiding surface contact with the guides 95 the slide is guided against forward tilting of the slide member.

. The width of the portion 84 of the slide mem- L ber is such that this portion of the slidemeinber lies between the side trame members 7.3 throughout a considerable zone, and thus elongated guides are provided which are of very much greater extent than the short guides in conventional inclinable presses. Furthermore these elongated guide surfaces are in contact throughout substantially the entire working stroke of the slide since, as shown for example in Figs. 1 and 2, the top of the slide portion Bil extends substantially above the top of the frame when the slide is at the top of its stroke.

This construction and combination for the above describeddriving connection wherein the power is applied to the outer sides of the Adie slide through the two. sets of link members provides for a highly accurate alignment of the slide throughout its working stroke with consequent efficient operation to give high quality work. And likewise it strongly resists tendency to cooking of the slide and thus jamming of the parts, and cooking which might result from unusually heavy unbalanced pressures is thus prevented. Likewise the pressure exerted between the two dies is maintained within the desired fine tolerance of uniformity which in turn likewise makes 'for higher quality work. And this is true in connection with a wide die slide of a width considerably greater than that in previous presses of this type of comparablesize, a width approximating or closely approaching the width of the bed and bolster plate.

The slide 25 is counterbalanced by a pneumatic counterbalance cylinder It!) aiiixed, as by bolts as shown, to the supporting channel shaped cross member |0| which extends across from one side frame member 23 to the other. The cylinder |00 is connected through pipe |04 to a tank |5 which is supplied with compressed air, at substantially constant pressure, through pipe |56 connected to suitable source of pressure air, such as the factory air line which is usually maintained under substantially constant pressure, if desired a suitable pressure control valve li being inserted in the air supply line |06.

A piston |08 is reciprocable within cylinder IBG and its piston rod |99 is connected to an extension H0, carried at the top of the slide portion 84, so that the proper assistance to the up-travel of the slide mechanism. through the pressure air in the counterbalance mechanism, is provided. It should benotedthat because of thevconstruction of the slidemember which provides the elongated upper portion 34, located between the side frame members 23, the counterbalance cylinder may be readily aflixed to a bracing cross section located back ofthe slide and its operating mechanisrn, and withva simple and effective connection direct to the upper portion of the slide mechanism to give a very simple and compact and effective arrangement.v n j Theslide 25 is likewise provided with laterally extending arm portions l l2, each of which extends laterally a distance sufficient to overlie the general vertical zone, on each side, in which the slide operating link mechanism is located, as shown more particularly in Figs. 2, 5 and 6. The

v rear face of each of these lateral extensions ||2 is provided witha vertically arranged slot which receives a guiding member carried by the bifurcated upper end 72 of the lower link member 13. As shown the rear `ofthe bifurcated portion is provided with a T- shaped projection I4, and the cooperating portion of the lateral extension ||2 is provided with the correspondingly shaped slot ||5 (see particularly Figs. 4 and 6). These parts are properly formed to have guiding and sliding lit, and( by means of this arrangement the cooperating guiding members referred to above are supplemented to provide additional quite substantial guiding means effective against thrust at the pivotal connection between the links 1| and i3 caused by oscillation of the eccentric strap links 'll during operation of the press. It will be noted that by the arrangement and construction of parts herein set forth the slide member is greatly strengthened and reinforced by the enlargements in the body portion thereof, approximately midway between the upper and lower ends of theslide, and that these guide carrying extensions ||2 may` be formed integrally with this heavier portion of the slide and may themselves be formed of adequate size to give the desired strengthl and rigidity tok withstand all the operating forces to which the press parts may be subjected, and, also, this construction permits of the side extensions ||2 being extended laterally sufciently to give adequate guiding of the operating linkage Without the necessity of Wideningfthe press frame or bed or in any way increasing the overall dimensions of the press. Therefore by the use of such rugged guiding construction for the link mechanism the twopoint pressure support operating mechanism may be utilized without widening the press frame or increasing its overall dimensions in any way and yet a very strong rugged construction is secured which permits of using comparatively lightweight operating linkage While maintaining ample rigidity and accuracy in operation under comparatively high operating pressures and even under very substantial unbalanced pressures due to the character of the Work. Also, the rigidity of the slide mechanism, and the effectiveness of the guiding mechanisms referred to is so enhanced by providing two vertical reinforcing projections or ribs H6, which extend upwardly from the reinforcingportion carrying the lateral extensionsl l |2 to approximately the top of the slide member.

Mechanism .for changing the effective travel of the slide, and the die carried thereby, is mounted upon the slide. This adjustment of the operating linkage is ysecured by rotation of the nuts 80. As these nuts are mounted to rotate :gemeen jus'ting fs'crewsf 13.1"tcn'bezie1evated' or. lowered', so

By such gauge, accurate adjusting of the slide to accommodate dies of different depth mayv be readily accomplished.

The main driving means, for work operation rof the press, in the illustrated embodiment, comprises a motor 280 which is provided with a suitable control box indicated diagrammatically at 20| (see, e. g., Figs. l, 2 and 3). This motor carries a drive pulley 204 upon the motor shaft, which is shown as provided with grooves to receive V-belts 205 which are in driving connection with the flywheel 206 provided with corresponding V-shaped belt receiving grooves.y The ywheel 200 runs continuously durin-g operation of the press on the shaft 2|0, which shaft is journaled'at the top of the side frame members 23, and carries on each end, outside of said frame members 23, gears 2| 4, each of which meshes with one of the drive gears 65, whereby, upon rotation of the main shaft 2|0, the gears E5 are rotated to cause rotation of the eccentrics and the eccentric straps 'I0 to thus affect reciprocatory movement of the slide, and the upper die carried thereby` Suitable clutch mechanism is provided, which is indicated generally by the reference numeral 2|5, this clutch mechanism not being illustrated in detail but comprising a driving member which is connected to the flywheel and rotates therewith and a driven member which is. mounted upon the main shaft 2|0, whereby when the two portions of the clutch mechanism are clutched together the shaft 2| 0 will be caused to rotate and affect working operation of the press, but when they are unclutched the flywheel with its clutch portion will continue to rotate but a brake will be applied to stop rotation of the other portion of the clutch and the shaft 2|0 and thus bring the press operating mechanism to rest. This'brake mechanism is indicated generally at 2|6, and it is preferably of pneumatic type, operated from the pressure air in the tank |05. The pipe 2|8 transmits pressure air from the tank to a valve control box indicated generally at 220 for controlling the operation of the clutch and brake mechanisms, the shaft 2|0 as shown beingprovided with a pressure air passage for transmitting the necessary pressure air to affect operationI of the clutch and brake mechanism referred to. The construction, as shown,` is such that the` press is automatically connected and disconnected from the driving motor at predetermined sequential point in the cycle of operation of the press. As shown the hub 61 carries a member 22|, which in turn supports a sprocket wheel 222, arranged to rotate coaxially with the hub 61. A second sprocket wheel 225 is mounted` adjacent the control box, these two wheels being interconnected by means of a drive chain so that the sprocket 225 is caused to rotate in synchronism with 'the rotation of the driving gears E5 and eccentric 66. The gears and the interconnecting chain for safety are preferably enclosed in an enlargement 22T, formed in the housing which encloses one of the gears 65 and the eccentric and strap mechanism associated therewith, this being shown at the right of Fig. 2 and at the left of Fig. 3, and also being 12 shown in Fig. Also a guard` channel 230 is provided which encloses'the sprocket lchain and safeguards the operator. As the hub 61 rotates through the 360'travel" ofthe work cycle of the press the `gears 4and the sprocket chain 225 cause corresponding 'actuation of the control mechanism so thatas the slide approaches to within a predetermined angular distance ofv upper dead center the pneumatic valves are 'actuated to disengage the two parts of the clutch and apply'the brake 2|5 to thus bringthe press slide and its operating mechanismv to rest at substantially upper dead center. 'Likewise the control box and valvemechanism therein is connected to the press Control 20| so that when `the control mecha complete cyclel in work operation and again be brought to rest at'substantially upper dead center in the manner` described. Other controls with other sequential loperational steps may be provided for by utilizing the control mechanism adapted to give' such' desired sequentialv operatin'g controls. y v' l Asillustratedin Figsl andS'the motor 200`is mounted upon a platform 240`which is supported at one end on coil springs 242, which springs are adjustably carried upon bolts 243 'supported in depending' position yfrom the upper flange of the cross chanel memberl |v0|. springs to the tension desired may vreadily vbe accomplished by means of the adjusting nutsl 2444.2 The opposite end' olf-the motorl platform is supported upon an adjustable supporting rod 246, the upper end of which is lconnected to the end of the platform by means of a pair of adjustable nuts or collars 241, Yand the lower end of whichis connected 'to a lsupporting flange 248, shown as formed integral within frame 20. This supporting'flang'e 248 has an opening therein through which the lower end of the rod 246 passes, 'the-'lower end` of thisy rodbeing also threaded and having' nuts or collars 248 threadedly positioned "on the upper and lower sides respectively of the supporting ilange 248. As indicated inFigL lat least one of these nuts 249 has a conical shape to provide a readily tiltable contact with the upper face of the flange 248, and'by proper adjustment of the rod 246 the platform 240 may be readily adjusted to meet operating conditions in the several operating positionings of the inclinable framework. In addition the tension of the springs 242 may be readily adjusted so that in the various positionings the motor will'be supported in proper position and the tension'of the drive belts may be maintained.

While the form of apparatus herein described constitutes a preferred embodiment of the invention, it is to be understood that the invention is not limited to this precise form of apparatus, and that changes may be made therein without departing from the scope of the invention which vis defined in the appended claims.
