Application filed June 12, 1908. Serial No. 438,137.

To all whom it may concern:

Be it known that I, FRED AsHWoR'rH, a citizen of lthe United States, residin at Beverly, in the county of Essex and ommonvvealth of Massachusetts, have invented certain Improvements in Presses, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like 'parts in the several figures. v

This invention relates to presses in which the presser members are relatively movable direction to eiect a pressing in another direction, o r in other directions, and. especially to presses in lwhich the presser members are relatively movable into different pressing relations to lwgorlr preferably carried by one of said memers.` t

In particular the invention .relates to presses of that type in which a pressureapply'ng member is movable into various operative relations to its bed, and for the sake of illustration the invention is shown as embodied in' a press of the type vmentioned which is especially adaptedfor forc-4 ing a die through sheet material, such as leather, for the purpose of dying out from said material blanks for manufacturing uses, although it vvill be understood that the invention is bynol means limited to application to presses of this character.

In presses of the type above referred to, as heretofore constructed, the pressure-applying member has usually been arranged to be moved by the operator into and out of the desired relation to the pressure-receiving member or bed. This has been a simple way Aof effecting a movement of the pressureapplying member into and out of position over a die placed -by the operator-upon a portion of stock lyinggupon the bed which has been selected by him as most suitable for a "blank .for which the particular die is shaped.

To improve the operation of this machine,`

,- ing member out of the selected operative' position after it has been actuated to erform a pressure-applying operation, sai means being preferably so constructed and ared operative position follovvs automatically the actuation to perform the pressure-.applying operation.

In its preferred embodiment the invention includes also means whereby the pressureapplying `member is moved automatically linto such position that it will, when actuated to perform a pressure-applyin tion, operate upon a portion of the ed previously selected by the operator. Preferably the means last mentioned is connected with orA includesl mechanism which also causes the member to perform a pressing operation when it arrives at the proper point above the bed, and is preferably-also conopera- `nected with or includes the 'above-mentioned means for returning the member to an inoperative position, preferably its initial position, after the pressing operation has beenv performed. y

In its illustrated preferred embodiment the invention comprises controllin means which can be moved over the bed in much the same manner as the pressure-applying member of the earlier constructions has been moved, the controlling means bein mounted, however, to move independent y of the pressure-applying member into a position above the bed corresponding substantially to that which it is desired that the pressureapplying member shall. be moved, and an ob3ect of the invention is the provision of controlling or selecting means, comparatively easy to manipulate, by which the operator can determine in advance of an automatic movement of thepressure-applyin member the point or position above the be at which the automatic movement will stop.

Preferably the means for starting 'the mechanism which edects the automatic movement of the pressure-applying member is carried by, or connected with the controlling. or selecting means above referred to, whereby the determination of the extent of movement .pf theA pressure-applying member and the initiation of such movement may be eiected quickly and easily by a single hand of the o erator. l

As hereinbeibre suggested, the mechanism started by the starting means after the controlling or selecting means has been moved into 'position to determine the movement ranged that the movement out of the selecti pressure-applying .moving ofthe pressure-applying member preferably includes not `onlymeans` for effecting a movement of the pressure-applying member into the selected ressure-applying relation to its bed, but a so means for effecting a out of various operativev relations thereto movements of the out of a selected and the means for effecting a pressure-applying operation of said member when it has come into a selected operative relation operate through the same connection with said member, and inthe illustrated form of the invention it will be operating connection may conveniently be constituted bythe support for said member. It will `be understood, however, that the invention is not limited tothe particular construction .of means for determining the operative relation to bed into which the pressure-applyingmember shall be moved, nor to'means for efectin arelative movement'of the presser mem ers of a press of this type whlch involves an automatic movement ofthe pressure-applyingmember into a selected pressure-applying relation to its bed as distinguished froma movement of the bed relatively to the pressure-applying member or simultaneous movements of lpresser membersrelatively to' each other, and it .will be'further understood that i v the inven-I tion is not limited to the illustrated mechanism for effecting in automatic succession and for the purposes described the relative presser membersl into and operative relation-to each other,` and an intervening relative pressureapplying movement.

' With the foregoingand other` objects 1n view, the invention is herein shown as embodied in apress rof the t .pe' known to the i lates'NoL 921,503,7granted May 11, 1909, for

trade as".cl1ckin press; that is, a press intended especial y for dying' out boot or shoe blanks. A machine of the general type 'is disclosed 1n of that 'herein illustrated i United States" Letters `Patent to. Arthur i improvements machines for cutting out thin sheet material such asupper leather for boots and shoes to which reference may be had lfor specific description lofv parts herein illustrated but not fully described.

-In theembodiment ofthe invention herein shown a vbed is provided over which a radial presser arm` carried upon a vertical shaft or column is movable into variousoperative positions with respect thereto, the arm being preferably'rildly attached to its shaft or column, and t e column being preferably aroperation, and means for seen that this commonover the bed, the

position, and preferably to or includes means for rangedy to rotate with the arm in its movements parallel to the surface ofthe bedand to reclprocate verticall with the arm to effect its pressure-applying movement. The bed of thls machine, like the bed of the mavchine shown in the patent above referred to,

operative position over the die and has been per- actuatedby suitable actuating means to form its pressurepplying operation whereby the die is forced through the stock, means is preferably provided for automatically returning the pressure-applying arm or member to an inoperative position with respect-to the die. Preferably also means is provided for moving the pressure-applying member automatically intoy the selected operative position, and in the illustrated preferred l embodiment this means is controlled by a device movable by the operator connections between the means for moving the pressure-applying member and the device being such that when the device has been moved to a position vertically above a point upon the bed at which it is desired that pressure shall be applied actuation of lthe means for moving the pressure-applying member will serve to cause said member to operative position above the se1ectedpoint. Preferably the device before mentioned for selecting the position above the bed into which it is desired that the pressure-applying member shall be automatically moved is connected with, or includes, means for e'ecting an actuation of the means for producing the automatic movement of the pressureapplying member. -As hereinbefore suggested, the means for effecting the automatic movement of the pressure-appl ing member into the selected operative position above the bed is preferably connected to, or includes, means which actuates the member to perform the pressure-applying operation when it has come into the selected oper tive also is connected returning the member automatically to an4 inoperative position after the pressure-applying operatlon hasbeen performed, these means being so interrelated that the various movements take place in automatic succession.

herein shown the device under control of the operator by which he may readily determine one of the limits of the automatic movements of thel pressure-applying membe moved automatically into ber hereinbefore referred to is connected to or includes means which serves not only to effect an actuation of the means for moving the member into the selected pressure-applying position, but preferably through suitable connections and Without further attention on the part of the operator serves to effect an actuation of the means for causing the pressure-applying member to perform the pressure-applying operation and preferably, still without further attention on the part of the operator, serves to eifect an actuation of the means for returning the pressure-ap'- plying member to an inoperative position.

V It will be seen from the following description that the illustrated construction embodies means for effecting a movement of t-he pressure-applying member which is substantially proportional to the movement of a controlling device and that the provision of such means constitutes an important feature of the invention.v The illustrated means for efecting or causing to be effected a movement of the pressure-applying member proportional to a movement of its controlling device comprises a lever having a fulcrum adjusted by the movement of said controlling device. Adjustment of the fulcrum of the lever serves of the movementsl of the parts between which the lever constitutes an operative conncction. lt will be understood, however, that the invention is not limited to the particulalr construction of means for elfecting' a movement of the pressure-applying member substantially proportional to the movement of a controlling device, and lthat the invention comprehends the provision of any suitable controlling means by which anv operator may determine in advance of its automatic lmovement the point upon the bed at which pressure will be applied by a pressure-applying member movable thereover when the means matic movement has been actuated.

Other features of novelty which contribute 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 disl closure of the invention vin the specification and drawings will either be pointed out in the following detailed description or included in the claims, or attention will' be directed to them both in the specification and claims, and itl willbe understood that it is my intention to cover by claims in this application all that is herein disclosed of my invention.

On the accompanying drawings which represent this invention as embodied in a press that may be used in dying out sheet material such as leather, etc., Figure 1 shows such a press in side elevation, partly broken away to show a part of the mechanism;

to vary the ratiol for effecting such auto- Fig. 2 is a rear elevation also showing the press as partly broken away; Fig. 3 is ay perspective view of the actuatingl mechamsm, the frame work of the machine being removed, and Fig. 4 is a section on line 4--4 of Fig. 3. 4 v

, O n the drawings, 2 indicates the` frame of the-machine which is arranged to support a bed 4 in any approved manner. The frame 2 is preferably extended to form an arm 6 which forms bearings for a vertically and horizontally movable column 8 on which a pressureapplying member 9 may be secured ,1n any preferred manner. The column 8 may be vertically reciprocated to move the pressure-applying member 9 toward or away from the bed 4 by an eccentric 10 mounted on shaft 11 and connected .with said column by connections 12 which may be adjusted by a hand wheel 14.

Mounted to turn freely on shaft 11` :is a belt pulley 16 provided with a bevel gear 17 which co-acts with a second bevel gear 18 mounted rigidly on a shaft 19 which is journaled in bearings inthe frame of the machine and provided with a. worm 20. Mounted to turn in bearings formed on the frame of theJ machine is a shaft 22 on which there is mounted a worm wheel 24 which meshes with and is turned by the worm 20.

`The worm wheel 24 is mounted on'its shaft 22 so as to turn independently thereon but may be connected with said shaft to actuate it by any convenient clutch mechanism as hereinafter described. Rigidly secured to shaft 22 is a crank arm 26 connected by link 27 with one arm of a bell crank lever 28 .which is suitably pivoted ,in the frame 2 and has its other arm connected by a link 29 with a crank arm 30 rigidly secured to a rockshaftl. A seco-nd crank -arm 32 is also rigidly mounted onirockshaft 31 and' is connectedat its outer end by a sliding block and slot or similar connection with one end of a lever 34, the other end of which is pivotally connected with a crank arm 36 rigidly secured to a rockshaft 38.-y A. bevel gear 40 mounted on rockshaft 38 engages a bevel gear 41 mounted 0n a second rockshaft 43 which actuates the vertically movable rod or column 8 about its axis by means of the segmental gear 44 mounted on said rockshaft 43 and meshing with a gear 45 on said vertically movable column 8.

Slidably mounted on lever 34 is a block 46 having a stem 48 (Fig. 1) that is journaled in a slide 50 longitudinally movable in bearings on the frame of the machine, the block 46 with the stem 48 constituting an adjustable fulcrum for said lever 34 whereby the bevel gear 58 meshing with a correspondingI secured a link 68 which oted at 82 on the frame 40 pressed plunger 98 (Fig. 4)

bevel gear 59 on a vertical shaft 60 carry-' ing a rigidly connected crankarm 61V pivotally connected by a link 62 to a movable carriage 64. Carriage 64 is movably mounted on ways having the form of a rTshaped ridge 66 formed on the part of arm 6 that forms a bearing for the vertically movable column 8. To the carriage 64 is pivotally is preferably forked and pivotally secured to a block 70 slidably supported on 'actuating arm 72. Arm 72 is provided with a handle 74 for convenience 1n ad'ustment and also with an annular portion 6 taking in a circumferential groove formed in an annular portion 78 of a lever 79, said annular ortion 78 surrounding column 8 wi'thsui'libient clearance to permit of the operation of the lever. The lever 79 which is held normally with its annular portion in raised `posit-ion by a spring 80 is pivof the machine'and is connected by means of a universal ,joint84 with a clutch actuating link 86 which is pivot/ally connected to one arm' 87 of \a bell crank lever mounted on a pin 89 secured in the frame 2 of the machine. On pin 8 9 is also pivotally mounted a wedge member 90 connected by a spring-91 with the arm 87 of the bell 'crank lever vto which actuating link 86 Aisattached and carrying pivotally lattached thereto a trip lever 92. Corresponding ends of wedge member 90 and trip lever 92 are drawn together by a spring 93 and the outer end oft-rip .lever 92 is provided with a catch or plate 94 which'normally extends over the end of a` simila'rlplate mounted on the other end 88 of theb'e crank lever above referred to. Wedge member- 90 coacts with a pinv 96 mounted on a spring in a collar. 100

eyedl to shaft 22, said plunger 98 being pressed forward by a of a series of recesses sprlng to engage one formed -in vthe side of gear wheel 24. Mounted on collar 100 is a second pin 102 arranged.v to contact with .the end of trip lever 92 on the rotation of collar 100 and shaft 22. Arranged'with one arm t ,1n the'path ofpin 102 is a second lever 104 6 screw threads on a pivoted at105 and connected by a link 106 to a third lever 108 which operates a clutch mechanism shown -in Fig. 2 that is similar to that just described and serves for .connecting belt pulleyf 16 to shaft 11, for actuating the :eccentric 10 and vertically reciprocating the pressure-applying member 9.

A locking device for slide 50 consists of a splitsleeve 112 that 'may be a part lof the frame 2 surrounding said slide and having 'its two sides-engaged by Voppositely .directed a head 115 that isy provided with teeth that mesh with the teeth of segmentalf gear 116 mounted on a crank arm that is rigidly. mounted on a rocking shaft 117 suitably 35 supported and carrying at its other end a This screw 114 provided with' second crank arm 118 having a cam roll 120 that co-acts with a cam 122 mounted to turn `with shaft 22.

In the operation of the machine the operator iirst determines the place over the bed 4 at which it is desired to apply pressure and then grasping the handle 74 moves actuatlng arm 72 to a position that is substantially vertically over said place. In case the machine is to be used in dying out sheet material such as leather, etc., the actuating arm will be moved to a position over the die 5 after said die has been suitably positioned by the operator on the stock supported on the bed. Movement of arm 72 to the desired position is transmitted by link 68 to carriage 64 which ismovedvon T-shaped ways 66 toa position corresponding to that of arm 72. By means of links 62 and 61 mo'- tion is transmitted from the carriage 64 to the bevel gear 59 which in turn by means of bevel gear 58, links 54 and 52 move slide 50 in its bearings in the frame of the machine to an extent corresponding to the movement of arm 72. movement of slide 50 is permitted by its locking device when the machine is at rest, as seen in Fig...3, at which time the cam 122 holds the-rocking shaft 117 in such position that split clamping sleeve 112 is held spreadv by a screw 114. It will be seen that every position of arm 72 over bed 4 will correspondto a-deiinite -posit-ion of slide 50 in its bearings and consequently to a denite position of block 46 onV lever 34, the stem 48 of `said block being vjournaled in said slide -50 and serving as a fulcrum of said lever 34.

In other Words, every position of arm 72 over the bed 4 will correspond to a different position of the fulcrum of lever 34. y

To effect an actuation of the mechanism for moving the pressure-applying member 9 to theposition over the bed ai which it is desired to exert pressure, the voperator depresses handle 74 on the arm 7 2. This movement of the arm 72 is without eiiect upon the carriage 64 and connected partslas block 7 0 vis *so mounted on said arm as to be mov-- able only longitudinally thereof. The depression of the handle, however, serves to turn lever 79 on its pivot 82 and this mot-ion is transmitted by link 86 to bell crank lever 87, 88'which is rocked on its pin S9 aud'acts through plate 94 and trip lever 92, moving Wedge" member 90 out of engagement lwith pin 96-l' O n the release of pin 96, as just described, plunger 98 is moved forward by aspring to engage one ofthe recesses in gear wheel 24 which isconstantly driven by its connect-ions with belt pulley 16 ask above indicated. Shaft 22 is thus clutched to gear wheel 2 4 byv means of lcollar 100 keyed on said shaft. t Immediately on the actuation of shaft 2 2 rockshaft 117 is turned by its cam'118, turning screw 114 and locking the slide 50 in the position it may occupy at that time. `By reason of the shape of cam 122 'which is indicated in Fig. 3, slide 50 remains locked in this position during practically the entire period of rotation of shaft.- 22, or until just before said shaft comes to rest. Every rotation of shaft- 22 also serves by means of crank arms 26 and 30, links 27 and 29 and bell crank lever 38 to rock the shaft 31 through a definite angle, the magnitude of l'which is determined by said connections. 'Ihis rocking movement of shaft 31 is transmitted byA means of crank arm 32 to the adjacent end of lever 34 Iwhich is movedl a constant distance for every rotation of shaft 22. rilhe constant movement of one end of lever 34 imparts a variable throw to the other end oit said lever, the extent of lwhich is determined by the position of fulcrum block 46 on said lever. This variable throw of lever 34 is communicated to pressure-applying member 9 by means of gear 45 mounted on the actuating column 8 for this member, segmental gear 44, vertical shaft 43, bevel gears and 41, rockshaft 38 and crank arm 36 and serves to turn said pressure-applying member 9 to a position over the bed corresponding to that indicated by arm 72. After the pressure-applying member has been thus movedover the place on the bed at `which* it is desired to apply pressure, said member is moved toward said bed to apply pressure and is then returned to its original position. The pressure ap`- plying movement of the arm is obtained by connecting the shaft 11 on which the actuating eccentric 10 for said members is mounted `to the beltpulley 16 and this is accomplished at a suitable stage in the rotation of shaft 22 when pin 102 rocks lever 104 on its pivot, thus by means ot' link 106 and lever 108 tripping the one revolution clutch that connects said shaft 11 and belt pulleyl6. The

return of the member 9 to its original posii tion is accomplished after its actuation to apply pressure by the return stroke of lever 34. i

'To insure 'the stopping of shaft 22 for one revolution trip lever 92 extends into the path of `pin 102 and is engaged thereby shortly after the starting of the machine. The engagement of trip lever 92 by pins 102 rocks said lever on its pivot and raises catch plate 94 outv ot engagement with bell crank lever arm 88, thus allowing Wedge member to be moved by spring 91 into such position that it will engage pin 96 at the roper time in the revolution of shaft 22 an move said-pinto disconnect the clutch and stopthe machine.

It Will be noted that the. actuating handle 72 is quite separated from the pressureapplying member 9 and in the operation of the machine is moved to the'desired location over the bed independently of Said member.

cated toward the bed t0 apply Thereafter, on the depression of said handle '7 2 the pressure-applying member9 is moved 'from its original position, in which it is preferably clear of the bed 4, to the location over the bed indicated by said handle, is recipropressure at the desired location thereover and is then returned to its original position clear of said bed.
