flpecillcation of Letters n at a 'ndmonm d aue 1:, 190a. Seria1 .Ifo. ;j;

., for conronarron or NEW Be it known that I, mo. Bucxmm a citizen of the, United States, residm at lBeverlyyin the county of Essex and o monwealth of Massachusetts, have invented certain Improvements in Presses, ofthe following descri tion, in connectionwith the accompanying awings, isa specificaures. v n

This invention relates, to presses in which the presser members are not only relatively movable in the pressing vdirect on, but-in .whichthey are also another direction or in other movable in tions, and especially to presses in which the presser re ivel members are relatively movable into difier-' ent pressing relations'to workpreferably 20 earned by one of said members;

" In particular the -1nvention relatesto a press in which a pressure-applying member is movable into different ressure-appl g relations to a bed upon w 'ch the wor or tool to which pressure is to be applied is su ported. v i

11 its illustrated preferred embodnnent the invention is shown as applied to a press in which a work-supportin presents a surface over which may be spread sheet material .from which. it is deslred'to die out blanks for"manufacturing uses, for ex amjple, blanks for boots or shoes 3 Letters Patent to Arthur Bates, 110,921,503,

machine of the oral of that just referred to is illu s t ratedin the U. S.

granted May 11, 1909, and a general object of the invention is'the improvement of the construction and 40 operation oi machines of this type. I b

An important object of the invention is the provision of mechanism for effecting automatically the relativemovement or movements which are necessary to'bring the parts of themachine into a desired relation to each other and which hitherto have usually provision in a machine of the type in which' been effected by hand, an important feature of the invention being the provision of such automatic mechanism in combination with means for checking the relative movement when the partshave .come into a desired relation to each other. 7

Another object of the invention is the a pressure applying. member is movable over t'ge' relations thereto, whether such moveme t be effected automatically or by hand,

fatented 5, 1911;

of means for checking this movement of 1 the presser member in advance of or before the end of its pressure applying movement. In its broade'st-aspec Patent, 968,117,;granted An '23, 1910, upon my-cos ndlng'application Serial No. "504,775, file June 28, 1909; Such claims as are made hereinwillbe directed, therets, this feature. of my a invention has been claimed in U. -S .Letters fore, to subject-matter which is'not common,

to-the construction herein shown and that shown in the said Letters Patent.

A further object'ofthe invention is the PI'OVlSlOIl of-means' controlled b the operator by which thedirections and 'ts of the lation are not necessarilyequal, that is the relative movement ofwsaid-members into in-.

em y

operative relation does not necessarily bring them into the relation to each other in which they were before their relativemovement into operative relation, and an important object of the invention is the provision of mechanism cooperating with the above-mentioned controlling means rqr efiecting auto matically a relative movement of the presser members into the relation to each other 'which has been selected by the operator and then eflecting a relative: movement of said members of uniform amount for successive,

operations into a difierentrelation to each other, said second movement preferablytaking'place in a direction difierent' from that of said first mentioned movement.

The relative movement of the presser members out of the selected operative relation, which movement in the preferred form of the invention is constituted by a movement of a pressure-applying member I out of operative position over a dial upon stock upon-a cooperating bed, is pre erably of an amount suflicient merely to move said member outof the. way of the operator while he is placing the die upon the stock for a success ve operation. It will be seen'therefore that an advantage of this 1 a Q I "a work supporting bed-mto difierent opera- 1 into difierent operative relations to its bad,

the operator and preferably without flilfther ing machines of this type is. that bothflthe construction in the usual method of operatsucoeeding -movement into operative position over the die in its new location and the succeeding movement out of operatlve position will be less than in a constructlon in which 'the member returns always to the same inoperative position, since the operator will usually place the die for a succeeding operation upon a portion of the stock not remote from that upon which the previous operation was performed. The strain and jar due to the momentum acquired by the ressu're-applying member in moving a long distance over the bed intoand out of operative position will thus be'avoided. Other objects of the invention are the provision of mechanism vwhereby upon a single movement of a single device'in a single direction the parts of the machine may be brought automatically into a predeg termined relation to each other, actuated to perform their functions, and then moved into a different relation to each other; the provision of means for initiating the move ments aforesaid which will itself be moved automatically out of theway. of the operator and of the work at'the'end offsaid movements, the provision of a construction in which the speed of the transmission of. the movement of a constantly moving part to the parts of the mechanism to be actuated will be uniform for successive operations,- 7 s but in which the amount of transmission may be varied in accordance with the'initial relative positions of the parts and the pro vision of means for preventing actuation of the mechanism except through the agency of the starting'means. Y 1

Withthe foregoing and other objects in view the invention is herein illustrated as embodied in a press of the '-known' to the trade as clicking press thatis, a'

ress intended especially for dieing out boot and shoe blanks, one-construction of this type of press being shown in the patent above referred to. In the press of the said patent a radial presser arm is rovided which is movable by the operator into dif-f ferent operative relations to-its bed. In theconstruction herein illustrated ;a radial presser arm is provided likewise movable but combined with mechanism: for moving it automatically over its bed', together pref- 1. erably with mechanism J for Lstopping' ji-tsg further movement when it has come; into,

the mechanism for moving said member; constructed to move said member j auto": matically into an operative relationzt gthe bed which has previously been selected attention on the part of the operator--eifec t f ing a pressure-applying operation fo f .means of a plurality of interrelated clutches.

These clutches are preferably so arranged that when one of them is operated by means under the control of the operator the others will be operated automatically in a succes-- sion which is dependent upon' the particular clutch first operated, the clutches being so connected to each other and to the parts which they clutch together that either the movement, usually of variable amount for successive operations, which serves to bring the "radial arm into the selected operative positionover .the bed, or the' movement,

preferably of unifornzt amount for successive operations, which serves to take it out of-suchposition,'may-becontrolled by either of two clutches and that when oneof said etwosclutches is-thro'wn by the operator to the movement of variable amount into operative positionthe other'clutch will be thrown automatically at the proper time to cause the movement of constant amount out oi -said operative position.

1 I the illustrated preferred construction f a-"third clutch is provided and is arranged operated between the operations of the other-two clutches without regard to the order in which said two clutches are oper- I ated, this third'clutchserving to clutch together parts whereby a movement of the radial presser arm toward and away flom its bed to perform a pressure-applying operation may be eiiected. 7

As herein shown the two clutches through which connections are made to 'efi'ect hor'i- -zonta'l1movement jjof the radial presser arm over its bed are arranged" clutch loose gears to their respective vertical intergeared constantly rotating shafts, both of the loose gears shown being in mesh with a large gear upon the column or shaft which carries the radial'presser arm. 1 'Ashereinbefore suggested, an important feature of the invention is the provision of means for preventing further movement of the pressurerapplyingmember when it has come", intoa-desired relation toits bed in a desired relation to said bed.=- ;Preferably.j-

combination with means .for moving said member over said bed, and .inthe construc structed and arranged that it serves not only toprevcnt further movement of the asfit comeslinto the selected operoperative position. The illustrated braking means is arranged to operate'upon one of the loose gears, this arrangement of the braking means serving in the construction shown to bring its braking action tobear upon the member in whatever direction the member may be moving since the loose gear is always in mesh with the large gear upon the column or shaft which carries saidmember.

Inasmuch as the operator may desire at times to move the 1 ressure-applying member, which in the il ustrated construction is 'the radial presser. arm, by hand into a different starting position from that in which it has been left by the automatic means, in the preferred embodiment the braking means is so constructed and arranged that the braking operation lasts only. long enough to insure bringing the parts braked to rest and then ceases.

Other features of novelty which contrib-v ute to the carrying out of objects of the invention hereinbefore enumerated or to other objects of the invention which will be apparent from a consideration of the disclo-' sure of the invention in the specification and drawings will either be pointed out in the 'following detailed descrlption or included in the claims, or attention will be-directed to them both in the specification and claims. In the accompanying drawings,-Figur e 1 shows in side elevation a press embodying.

the invention of this application; Fig. 2 is a view in rear elevation; Fig. 3is a plan view of the press shown in Fig. 1; Fig. 4 is a detail view drawn to a'larger scale of the four-armed lever and connected parts at the back of the machine; Fig. 5 is a horizontal section through the expanding ring clutch associated with the gears 32 and 38; Fig. 6 is a view, part1 in vertical section, of the clutch associate together with a view of the brake disk carried by the section of t e clutch associated with the gears 34 and 40 and also of the clutch which connects the brake eccentric to the gear 40. 4 Upon the base 2 of the frame of themachine is supported a head 4 having bearings for the vertical shaft or column 6 which carries the radial presser arm 8, said shaft or column 6 being mounted in said bearings in the head 4 both for oscillation about its.

axis and for reciprocation longitudinally of its axis. The resser arm 8 is'arranged to oscillate with the shaft or column 6 to bring it into different operative relations to the cooperating presser member which, in the illustrated construction, is' constituted by a stationary bed or block- 10. supported upon a bracket 12 attached to the head 4.

' gear.

with the gears 32 and 38,-

ar 32; and Fig. 7 is a detail The means for vertically reciprocating the shaft or column 6 may be and preferably is the same as that shown in the patent above referred to and comprises a s indle which is swiveled in the column 6 an is linked to an eccentric upon the main shaft 14 to which a normally loose belt pulley 16 may be clutched by an expanding ring or other suitable clutch. Carried'by the pulley 16 is a bevel gear 18 meshing with another bevel gear 20 on a cross shaft 22., A second bevel gear 24 on the cross shaft 22, or. formed on the gear-'20, meshes with a bevel ar 26 on a. vertical shaft 28, the shaft 28 ein thus kept constantly rotating while'the be t' pul ley 16 is connected to a source of power.

The vertical shaft or column 6 carries near itsupper end a large segment gear 30v by which it may be oscillated to bring the radial p'resser arm 8 into different pressing relations to the bed 10. Meshing segment gear 30 are ears 32 and 34, the gear 32 belng mounte pandin he car 34 is mounted on asecond on the shaft 28 and arranged to be clutched thereto by an exf ring clutch-associated with said 3:

vertical sha t 36in the ,upper partof the head 4 and is arrangedto be clutched thereto by an expanding ring clutch'associated with said gear, the shafts 28 and 36 being connected together by gears 38 and 40 of equal diameter and rigidly attached to the respective shafts. The clutches forthe gears 32 and 34 are 0 erated from the centers of.

the respective s afts 28 and 36, two operating l mechanisms being provided for each clutc i operating mechanisms of the two clutches are substantially thesame, so that a descri tion of the two operating mechanisms in t e clutch shown at the right in Fig. 2, at the left in Fig. 3 and in detail in Figs. 5 and 6 .will apply equally as well to'the operating mechanisms of the clutch associated with the gear 34, the reference characters applied The constructions of the corresponding l upon the drawings to parts of the latter clutch being the same as those applied to corresponding parts of the other clutch except that they are primed.

Attached to the hub of the gear 32 is a disk 42 having a de ending flange 44 concentric with the sha t 28, extending within the rim of the gear wheel 38 and surrounding an expanding ring 46 attached at one end to saidgear wheel .38 by screws, 48. A lever 50 pivoted atv52 upon the gear 38 has one arm extending into a recess in one side of.the shaft 28 and another arm in engagement with the other end of the ring 46. Movement away from the center of the shaft 28 of the end of the lever 50 which extends into the recess insaid shaft serves to expand the ring 4-6 and thereby'to clutch the gear 32' to the gear wheel 38. and shaft 28. Such movement of the le ver may be efiected through eitherfon'e' of two mech 28 will be effected-by the action orapi or plunger 54 slidablymounted in acentral, bore in the upper. endlof the shaft 28, and, having a tapered, lowerrend' arrangedtof engage a beveled side ofthe 'end of the lever 50 which projects into therecessin the side of said shaft and Jwhendepressed to force this end of the lever away from the.

The parts hereinbeforedescribed which control the movement ofthe arm 8 in one direction into operative position have 'upon the other-. side of the-Jnachine substantial duplicates: which control ='the movement of the arm in'the other direction into operative position and these duplicate parts are indi-: cated 'upon the drawings "where shown by corresponding reference characters primed.

The segment. plate 92 is'not divided into two parts after the manner of the p but is cont-inu ousthroughout its extent.- e

plate is, however, provided with two supporting stems 94, 94', which have pin and slot connections with the respective levers 95 and 95' The pins upon the ends of the levers 95, 95' rest normally in the bottoms ofthe slots in the stems 94, 94, so that when,

either lever is operated to depress the plate 92 against the actionof its supporting springs the slot in the stem connected to the other lever will pass freely over the 4 on said lever and thus not disturb the pos1- tion of said lever.

From the fo oing description will be 'seen that when t cam 84 is turned toward the left in Fig.3 it will cause the cam 72 to depress the rod'76- and the left-hand half of the split ring 82 and thereby operate the I jclutch which connects the gear 32 to the gear wheel 38 and shaft 28, so that the arm 8 will also be moved toward the left in this figure.

V The arm'of the lever 118 to which the Hill: is connected projects beyond the end'of the jaw 110 so-that when this arm of the lever moves toward the front of the machine, as shown in Fig. 3, it will serve to draw the jaws together and cause them to exert a braking action upon the disk 116 and when it ismoved toward the rear it cause the jaws to'open.

Means is provided for Cally, a closing mechanisnnthe closing of the aws to brakethe disk-11621.8 the arm 8 reachesits desired limit of movement in either. direction, and this means, in the illustrated construction, comprises an eccentric 122 sur-v YV 1 the hub'of the gear wheel 40 and p i to be-clutehed 'to this gear wheeL An eccentric collar 124 surroun the eccentric 122 is -yieldingly connecte at 126 Rotation of the eccentric 122 after 't has been clutched, to the ar wheel 40 operates first to up the bra e to-the disk 116 and then tore ease the brake just before the eccentric .is unclutched from the gear wheel 40. The means for efiecting the clutching of the eccentric 122 to the gear wheel 40 comprises a'pin 128 carried by the eccentric 122 and spring-pressed toward the gear wheel 40, thegear wheel 40. having I an opening adaptedpin has been released and the opening has come into proper relation to it. I

I The pin 128 is normally held out of clutching relation to the gear wheel 40 by the en-v gagement with a projection on said pin of efl'ecting automati through the. described opening and the wedge-shaped end of a lever 130 pivoted 4 upon the frame of the machine and con nected at its other end to a link- 132 con-' nected to an arm 134 attached to a rocksha'ft 136 mounted in bearings on the head 4. The wedge-shaped end of thelever 130 is arranged to enter between the under surface of the eccentric 122 and the saidprojection on the clutch pin 12.8 and thereby" thepin to he'pulled away from the I to cause the upper end of the rod 76 to ride trio 122 has rotated tobring into operative relation to, the wedg' shaped end 0 spring. A second arm 137 attached to the -rod 58. When the rod 58 is raised bythe "recess of the gear wheel 40 when the the pawl 138. As the eccentric 122 rotates gear wheel 40- against the tension of its rockshaft 136 carries a pawl 138, springpressed toward a collar140 clamped to the depression of the forward end of the lever 60 to effect a clutching of the gear 32 to the. shaft 28 and thereby rotationof the arm 8 toward the left in Fig. 3, the pawl w1ll spring under the collar 140.

After the arm 8 has rotated far enough up over the cam 72 the lowering of the rod 58 by the action of the spring 64 upon the forward end of the lever 60 will cause the collar 140 to depress the arm 137 to which the pawl 138 is attached, and through the arm .134 and link 132 "move the -wedge-. shaped end of the lever 130 out of operatlye relation to the clutch pin 128, thus permitting the pin to drop into the p1n'rece1v1ng ear wheel is turned .to bring'this recess Into proper relation to the pin, and-thereby effecting a. clutching of the eccenric122 to the gear wheel 40. 1

Turnin of the eccentric 122 with the gear whee.

40 servesdur' the first half of 1ts rotation to effect a b i 'firing of the gear 32 and through it of the segment gear by the closing of the jaws 110, 112 upon the disk 116, thereby serving to stop the arm 8 in the position to which ithas been moved by the gear 32. The eccentric 122 rema1ns clutched to the gear wheel 40 for onl one rotation of said gear wheel. The unc utching of the eccentric 122 from the ar wheel 40 at the end of this rotation is effected through the following mechamsm:

Connected by link 142 to the joint 126 between the eccentric collar 124 and the lever 118 is an arm 144 fast upon a rockshaft 146 which carries at its outer end a pawl-tripping arm 148 arranged to engage the tail of with the. gear 40 after it has been clutched to said gear by the release of the pm 128, the arm of the lever 118 to which the eccentric collar 124 is connected is moved first toward the rear, thereby tnrnin through the link 142 and arm 144 the roc haft146 in a direction to cause the pawl-tripping arm 148 to move the pawl 138 from beneath the collar 140. 1

7 As soon as the pawl has been moved from beneath the collar 140 a spring 150, attached to the arm 134, moves said arm in a direction to cause the wedge-shaped end of the lever 130 to come into unclutching relation to heclutch pin 128, so thatmhentheeccene; the pin' f-1281 .the lever 130 the with; drawn from its recess in the ar'wheeL and the eccentric be unc utchedifr'om} mechanism said gear wheel. i It will be noted from the foregoing description that this unclutching takes place atthe same point at which the vclutchmg took place, and that the eccentric is at this time in its brake releasing position.

The brake is therefore released from the disk 116 and the gear 32 is free to be rotated.

This is an important provision, especially when the brake has just operated to brake the end of the movement of the arm 8 out of the operative position in which it performed a pressure applying operation, inasmuch as it leaves the arm '8 free to be moved by the operator. It will be understood that the'foregoing description applies equally to the corresponding parts on the other side of themachine, and that the rockshaft 136 has pawls above refered to.

After the arm 8 has been brought into the desired operating position over the bed, it is actuated to perform a pressure-applying operation and such actuation preferablyfollows automatically its, location in the desired operative position.

In the illustrated embodiment, the automatic actuation of the arm 8 to perform a pressure applying operation is effected throughthe following mechanism: The vertical shaft or column 6 is connected to suitable reciprocating mechanism operated from the shaft 146, the said mechanism being preferably the same as that disclosed in the U. S. Letters Patent 921,503, above referred to. The belt pulley 16 is preferably arranged to be clutched to the shaft 14 to effect an actuation of the reciprocating for the shaft 6, and this clutch mechanism is preferably that disclosed in the coendingapplication of Arthus Bates,

Serial 1 0. 443,060. Included in this clutch mechanism is a member 152 which releases a pin of. a one rotation clutch at the end of one rotation of the shaft 14 by the pulley 16,-and this member is arranged to be lifted out of its pin releasing position to cause a clutching of the pulley 16 to the shaft 14 by a lever 154 having a catch plate 156 arranged .to engage under a catch plate 158 upon a lifting arm 160 pivoted upon the member 152 and yielding-1y pressed toward the end of the lever 154. ;In the illustrated construction, the machine is arranged to stop with the shaft 14 unclutched from the pulley 16 and with the lever 154 in such position that its catch plate 156 lies above the catch plate 158. Itwill befseen, therefore, that lifting of the lever 1; 154 when it is in this psitin will any efiect upon the member 152. In order of the lever 154 into that the f'inember 152 may be liftedout of itsclutchreleasin positiomthe-fllth plate 156 'inuatbebroug t-beneath the catch plate; 158.

Inflthe illustrated construction, movement position to bring its 1 catchplate 156 beneath the catch plate 158 is effected through the following mechanism Pivoted upon the back of the machlne is a lever 162. which is connected atone end byia link 164 to the lever.154 and at its. other end by a link 166 to the lever 60. As 16 the rear end of the lever 6O vis .raised when the rod 76 is depress'edto effect a clutchingof the gear 32 to 'theshaft 28, the end of the lever 162, to which the link 164 is attached, will :be lowered and thelever 154 will therefore be lowered to bring its catch plate 156 beneath the cat-ch plate-158. When the rod 76 has been carried 'bythe arm 8 into such positionthat its upper end rides up over the cam '72 thereby permittin the forwardend of the lever'60 to be -raise by-the spring 64 -and therear end to be again depressed to effect an unclutchin'g of the ar 32 from the shaft 28, the end of the lever 162 to which the link 164 is attached will be raised and the lever 154 will be raised, thereby lifting the member 152 out of clutch releasing position and effecting a clutching of the pulley '16 tot-he shaft 14. This. clutching of the pulley 16 to the shaft 14 .eflects-an actuation of the reciprocating mechanism for the shaft ,or column 6, and thereby a pressure-applying operation of the arm 8.

, operation startsat the same time that the braking of the movement of the arm into operative position is effected, so that no time is wasted between the movement of the arm into operative position and its actuation to perform a pressure-applying operation.

It will be understood that there are two levers 154 and 154 either of which may be moved into a position to cause its catch plate 156 or 156' to catch beneath the catch sired operative position.

plate 158 upon the lifting arm 160.

It. will be further understood that the lever 154' is connectedby a link 164' to one end of a lever 162 which is connected at its other end by a link 166' to the lever 60', the arm 154 effecting the clutching of the pulley 16 to the shaft 14 after the arm 8 a as been moved by the gear 34 into its de- After the arm8 has been actuated to perform a pressureapplying 0 eration it is preferably moved automatical y into an inoperative position s e rp y g or into-a not over the the work upon which the preesure zpplying operation has 'beenperfo m d, e P

.In the illustrated embodiment, the move-1 ment of the pressure-appl Fmember out operation-and thea'utomatic of the operative position in w 'ch the pressure-app ing operation has been rformed' is efiecte through that one ofthe'two' loose gears which has not been utilized to move the member lnto operative position; and mechanlsm -1s ;provi ed which is operated upon the return'of the pressure.'applying member to ts. uppermost position after effectlng the pressure-applyin operation to effect a clutching to its sha of the gear wh1ch 1s cause the-movement of the pressure-applylng member out of'the oerative pos1t1on 111 which it has effected t e pressure-applying operation.

The illustrated mechanism comprises a lever 168'forked at its forward end and havmg $1113 entering from opposite sides a circum erential groove in a collar 170 attached to the adjusting rod 172 carried by the shaft or column 6. The lever; 168 is pivoted at 174 upon the head of the machine and at its rear end is connected by arod 176 to one end of up and down with the slide plate 190 and to.

be tilted with. respect to said slide plate to bring it into different relations to the operating mechanisms for the clutches to be hereinafter described. The arm 194 of the fourarmedvlever is connected b a link 196 to the lever 60', the connection tween the arm 194 and link 196 being a in and slot connection and the length of 't e slot being substantially equal to the extent of the vertical movement of the slide 190. The arm 194 is connected by a link 196' to the lever 60', the connection between the arm 194' and the link 196 being similar. to that between the arm 194 and the link 196.

If the forward end of the lever 60 is depressed by the action of the cam 72 on the rod 76 to efiect a clutching ofthe gear 32 to the shaft 28, the link 196 will be raised and the four-armed lever will be turned about its fulcrum 192 into the position shown I r in Fig; 4, i In this position the end of the arm 198 of the four-armed lever will lie vertically'beneath a lifting plate 200 carried by the clutch-actuating rod 202' and the end of the arm 198 will be moved out'of its vertical position beneath the lifting plate 200 on the clutch actuating rod 202. The four-armed lever will rema n in this position until it is tipped in the other direction by movement of the lever 60. When the arm 8 has been actuated to perform the thus eifecting an actuation of the clutch controlled by it. The movement imparted to the lever 182 through its connections with the adjusting rod 172 is sufficient .so that when the slide 19.0 reaches the upper limit of its movement the lever 182 will continue to move until the pawl 186 is brought out of engagement with the tooth 188. The slide 190 is thus permitted to return to its lowermost position carrying with it the'fourarmed lever.

It will be seen fr'omthe foregoing description that if the rod 76" is depressed by the cam 72', thereby depressing the forward end of the lever 60', the link 196 will operate to tip the four-armed lever toward the right in Fig. 4, thereby bringing itsarm'198 beneath the lifting plate 200 upon the clutch operating rod 202 and causing the clutch controlled by it to be operated insteadpf the clutch controlled by the rod 202.

The clutch operating rod 202 is connected at its upper end to one arm of a lever 204 pivoted upon the machine head and forked at its other end to embrace a collar 206 formed upon or attached'to the upper end of a clutch actuating sleeve 208 which surrounds the clutch actuating pin 54: and is tapered at its lower end where it engages the beveled end of the lever 50. The collar 206 has upon its upper face at one side a depression 210 provided with inclined side walls, and a correspondingly shaped projection upon the frame adjacent to the collar fits normally into the depression in the collar.

The collar 206 with 'its sleeve 208'is held normally in its uppermost position by a spring 212' surrounding the sleeve 208 and extending between the lower-face of the collar. 206 and a flange 214 upon the upper end of the'shaft 28. When the collar 206 and its sleeve 208 are depressed by the action of the rod 202 on the lever 204, therebyv serving to move the-inner end of the lever 50- away fromthe center of the shaft 28 and to effect the clutching of the gear 32'to the gear wheel 38 and shaft 28, a pin 216 upon the under side of the collar 206-is engaged by a pin 218 upon the flange 214 of the shaft 28 and the collar 206an'd sleeve 208 are rotated with the shaft 28 thus preventing. the projection upon'the frame from again entering the depression 210 upon the upper face of the collar until the collar and its sleeve have made a complete rotation with the shaft 28. It will thus be seen that the' clutch which is operated by the u ward movement of the rod 202' under the influence of the arm 198 of the four-armed leveris a one rotation clutch.- The clutch operated by the rod 202' is similar in construction and operation to thatroperated by the rod 202 and the foregoing description with primed reference Y numerals, will apply equally as well to it.

"Since thegear which is clutched to its shaft to effect the movement of the arm 8 out of the operative position in which it has performed the pressure-applying operation is clutched to the shaft for one rotation only,

. tive position in which it has performed the pressure-applying operation is released,

mechanism is preferably provided for applying the hereinbefore described brake to the gear 32in the same manner that it is applied at the end of the movement of the arm 8 into itsoperative position. This mechanism' preferably comprises, for the most part, the same mechanism as that used to effect an application of the brake at the end of the said movement into operative position. Upofl the rod 202 is carried a collar .220 into engagement with the under side of which apawl 222 mounted upon the arm 137 attached to the rockshaft 136 .is adapted to be pressed by its spring when the rod 202 is raised to operate the clutch controlled bly it. As the rod 202 is again depressed by t e action of the spring 212 in returning the collar 206 and sleeve 208 to their uppermost position at the end of a complete rotation of the shaft 28, the rockshaft 136 is rocked in the direction to effect through its connections with the lever 130 an application of the braking jaws to the disk 116 in the manner hereinbefore described.

The description of the operation of the separate mechanisms has been included in the detailed description of these mecha nisms. The operation of the machine as a whole will now be briefly set forth. The

operator, having selected adie 11 of the;

shape of the desired blank to be diedrout from the stock, places itlupon the sto k upon .the bedfl10 over a portion of said stockwhich hagbeen selected by him as most suitablefor the said blank, the, radial pressureapplying arm 8 being at this time out of operative relation to the die. If the op. erator in layingthe die upon the stock finds that the arm 8 is over any part ofthe stock ,upon which he desires to lay the die, he can easily ushethe arm out of this position,

since t e arm, when the machine is not in 10 operation, is free to rotate with the vertical shaft' or column, 6. Having placed-the dle j 11 in the selected location upon the stock,

-the operator grasps the handle 98 and swings the arm-84 the direction tobring it-over the die :11. QJAs the operator starts to move the arm 84, the handle 198 turns about its pivot 108 in one direction or "the other according to thejdireotion ln-which the arm 84 is to be moved and through the as the'cam 72 or the-cam72'. engages theup-- per end of the rod76= or "the rod 76. to de press the'forward end of the lever 60 or the lever 60. When the arm- 84 has beenturned far enough to bring it into the desired posi 'tion over. the bed 10 and die 11 the operator releases the 'handle98 and" the spring 88 moves'the locking rod 86 again. toward the locking plate 92, thus bringing its end 'remote from the operator..into engagement withone of the teeth 90 of said plate, thereby. locking the arm 84ein the position to which it has beenmoved. Assuming that the arm 98 has been moved toward the left in Fig. 3, the forward end of thelever 60 will be depressed by the engagement ofcam 72 with the upper end ofrod 7.6, and the rear end of the lever60 will be raised, thus,

through the rod 58, lever 56 and pin 54 clutching the gear 32 to the. shaft 28. Raising of the rear. end of the lever 60 also. raises the'end of the lever 162 to which it is connected by the link 164 and depresses the other end of this lever, thus permitting. the catch plate upon the lever 154 to.come'beneath the catchplate upon the lifting arm 160. The gear 32 having been clutched to the shaft 28 will rotate the segment gear 30, thereby causing the arm 8 to turn toward the-left in Fig. 3 until it brings the rod 76 into such position that it rides up-over the cam 72 thereby efiecting an unclutching of the gear 32. Lifting of the rear end of the lever 60 serves also throughthe link 196 to tip the four-armed lever into the position shown in Figs. 2 and 4, whereby its arm 198' is brought beneath the lifting plate 200.

As'the rod 58 has been raised by .the upward movement of the rear end of the lever 60, the pawl .138 upon .the am 137 has caught beneath thecollar 140 on said rod;

As the arm 81 swingsinto the positiontocause thefuppe'r end of the rod 76 to ride up over the cam "72, the spring 64 lifts the forwardend of the lever 60 and the rod 76 e 140 upon the.pa-wl138,'elutchingof the brake eccentric 122 to the'gear4O and -the braking o'fthe movement of the arm 8 through the action of the brakejaws 110, 112 upon the 'br'ake disk 116 carried by the gear 32; De- ."pr

ion of the rear end of the lever 60 also depressesthe end of the lever 162 to which it is connected and raises the-other end, thereby raisin thelever' 154 which carries with it the li ing arm 160- and brings the s'haft-14'and pulley 16- is thus permitted to act and these parts are clutched together -for one rotationof. the pulley 16. The

clutch-releasingmember 152 out of operative; v relation to" the, clutch betweentheshaft 14 'and the pulley '16; The clutch between the movement ofthe pulley 16 being thus trans mittedto the shaft 14'efi'ects' through the shaft 14 a vertical reciprocation of the :ver-

tical' column or shaft 6, ;togetherwiththe radial pressureaptplying arm 8. The move ment of the sha to bring the ressure applying arm 8 into connections 168, 176, 178,180 to move the or column 6 downward.

9 contact with t e die 11 operates through the lever 182 downward about its pivot and thus bring its pawl 186 into engagement with the under side of the teeth 188 upon the slide plate 190. Return of the shaft 6 to its uppermost position effects through the same.

connections a movement of the lever 182 in the opposite .directionilthus raising, the slide plate 190 and throug the arm 198 ofthe 'four-armed'lever carried by said plate, the *lifting late-200', the clutch-actuatingrod 202' an connections2047, 206', 208, effecting aclutching of'th'e gear 34 to the shaft 36 for one rotation, of said'shaft. Inasmuch as the "shaft 36 rotates in a direction opposite to' that. of the shaft 28, the gear 34 will be rotated in the direction'opposite to that of the. gear 32 and the segment gear 30 will likewise be turned in a direction different from that in which it turnedin bringing'the arm 8 into operative position over the die 11. When the gear 34 is unclutched. from the shaft 36'at theend ofone complete rotation'of said shaft, the return of the rod 202' to its. lowermost position operates through the sleeve 220"and pawl 222' upon the arm-137 corresponding to arm 137 to effect a clutching of the. brake eccentric 122 to the gear 40 and an. application of the brake jawsllO, 112 to the disk 116 upon t-he'gear 132. I

-.As hereinbefore pointed out, the jaws 110 to the disk 116 before the eccentric 122 is unclutched from the gear 40 at the end of one complete rotation of said gear. This leaves the arm 8 free to be turned with the shaft 6 to any position with respect to the bed in which the operator may desire to have it, provided its automatic movement out of operative position over the die has left 1t in an undesirable relation to the bed. The movement into an inoperative position imparted by one complete rotation of the gear 32 or the gear 34 is usually sufiicient to take the arm entirely out of the way of the operator, so far as the succeeding die placing operation is concerned. It may happen, however, that the operator desires to lay the die upon a portion ofthe stock remote from that last died out and in such case he may desire to have a different movement of the,

arm from that automatically provided. For

this reason the arm is left free to be moved desires, swing said arm or member into the selected operative position by hand and thereafter actuate the mechanism through which the pressing operation and the movement out of operative position are automatically eifected. When it is desired to operate the machine in this manner the operator will grasp the handle 98, after the radial arm or presser member'S has been swung by hand into the selected operative position,

and swing the arm 84 slightly to one side or the other, the direction in which the operator swings the arm 84 depending upon the desired direction of the movement of the radial arm or presser member 8 into inoperative position. As above pointed out the movement of the arm 84 will cause the cam 72 or the cam 72' to depress the associated rod 76 or 76 and initiate the movement of the automatic mechanism hereinabove described, the .various operations performed by this mechanism thereafter taking place in automatic succession. The radial arm or presser member 8 being already-in operative position the arm 84 will be swung to one side only far enough to effect the actuation of the automatic mechanism and will thenbe returned to its position over the radial arm or presser member before the said mechanism has operated to effect a lateral movement of said arm or member, and thus the.

radial arm or presser member will be caused toperform the pressing operation in the po-v sition to which it has been moved by hand. 1

It will be noted that an important feature of the iIHBIIfiOIl which contributes to the compactness of the construction illustrated is the provision with a single clutch of two operating means for said clutch, one of which operates the, clutch in such manner that it clutches two parts/ together for a movement proportional to the movement of a part included in said operating means, and the other of which operated said clutch in such manner that it acts as a one rota t-ion clutch. After the clutch has been op erated which moves the arm 8into its operative position over the die, thus bringing the arm 8 beneath the arm 84, the release of the clutch permits 'the plate 92 to be moved back to its uppermost position by its springs 93, thus permitting the remote end of the locking rod 86 to be -moved back beneath said plate. When the remote end of the rod 86'is in position beneath .the' plate 92, neither the rod 76 nor the .rod 76 can be depressed by the cam 72 or the cam 72 and therefore when the arm 8 is moved out of its operative position over the die by the gear which has not been clutched to its shaft to move said arm into operat1ve position the arm 84 will be carried with the arm 8 and will come to rest in acentral position above the arm 8. -This movement of the arm 84 with the arm 8 serves to take it out of the way of the operator simultaneously with the movement of the arm 8 for this same purpose.

It will be noted further that this movement of the arm 84 with the arm 8, when the arm 8 moves out of its selected operative position, serves to leave the arm 84 in such position that when the handle 98 is grasped by the operator to move the arm 84 over the die. 11, it being immaterial into what new location with respect to the die the arm 8 has been moved, the said move-- ment of the arm 84 will serve to operate the proper clutch for effecting the movelations to each other, means for effecting a.

relative pressure applying movement of said members, starting means under the control of the operator, and means separately controlled from said starting means for pre venting a continuation of the first-mentioned relative movement of said members during the last-mentioned relative movement of said members.
