Specification of Letters Patent. Patented Jan. 17, 1922.
Application led January 21, 1918, Serial No. 213,038. Renewed .Tune 15, 1921., Serial No. 477,862.
To 1.71 whom it may concern Y Be it known that I, Harrison H. EATON, a citizen of the United States, residing at Beverly, in the county of Essexand Uommouwealth of Massachusetts, have invented certain Improvements in Presses, of which the following description, in connection with the accompanying drawings, is a speciiication, like reference characters on the drawings imlicating like parts in the several iigures.
This invention relates to presses in which the presser membersare relatively movable in a direction to effect a pressing operation and also in other directions so as to bring the members into different pressing relations to work preferably carriedby one of said members.
In particular the inventionrelates to presses of the type in which a pressure-ap plying memberv is movable into various operative relations to its bed. For the sake of illustrationthe invention is shown embodied in a press of vthe Vtype mentioned which is especially adapted for forcing a die through sheet material, such as leather, for the pur-A pose of Vdiv/sing out from the material blanks -for manufacturing uses, although it will be understood that the invention is not 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 tofbe moved by the operator into and out of the desired relation to the pressure-receiving member or bed. It is an-object'of the present invention to provide improved power means for moving` the pressure-applying member, the said means being characterized -by simplicitiY in construction and operation and economy in manufacture. This arrangement of power means for moving the presser members will prove less fatiguing to the operator and will withal enable him to locate the pressure-applying member over the selected portion of the bed with the same accuracy and with 'greater ease than that which accom panied the positioning of the pressure member by hand. In the preferred form of the invention the power means for shifting the presser members to bring them into different relations to each other is so constructed and arranged as to be under the control of the cperator at all times.
Conveniently, the power meansfor causing relative-movements of the 'pressermem4 bers into and out of operative relations with each other is controlled by manually operable means. Preferably theV means last' mentioned is connected with vmechanism which may be operated at the will of the operator to determine the time at which relative pressure-applying movement of the lpresser members shall take place in carrying out those operations upon the work for which the machine is designed. y
In the particular construction herein disclosed, means are'provided for causingdis` connection of the power means, which moves the presser members laterally relatively to each other, from said presser members, said disconnection taking place as the machine is thrown into operation to cause Ithe applicationA of pressure. This arrangement adds to the ease and rapidity with whiehthe ma-Y chine may be operated. Tere it not for this construction, the operator would have to disconnect Vsaid power Vmeans.l byl a conscious effort properly timed with respect to the other operationsin order to secure'vthe best results. In a practicalfformof the invention, the means for causing disconnection of the power means so that the lateral Vrelative movement of the presser members is discontinued, is so constructed and arranged as to be operable by the manually operable means for controlling vsaid power means.
Other features of novelty which contribute to the carrying out of objects ofthe invention hereinbefore enumerated or to other objects of the invention which' will be apparent from a consideration of the disclosure of the invention in the speciiication and drawings will either be pointed out in the following detailed description or in-y cluded in the claims, or` attention will be directed to them both in the specification and claims, and it will be understood lthat itis my intention to cover by claims in this application all that is herein disclosed of my invention.
On the accompanying drawings which represent one embodiment of the invention,
Fig. 1 is a view in side elevation of a clicking machine disclosing one embodiment of my invention;
Fig. 2 is a plan view from above with parts broken away to show more clearly the connection between the operating means and the pressure member; and
Fig. 3 is a detail view on an enlarged scale taken along the line 3 3 in Fig. 1 lookin in the direction of the arrows.
As ilustrated the invention'is shown e1n- `bodied in a machine of the type disclosed in the patent to Arthur' Bates, No. 921,503, granted May 11, 1909. This machine comprises an approximately C-shaped frame member 4 having bearings 6 for a vertical post 8 carrying a resser member 10 fxedly secured thereto. he other presser member 12 is ordinarily termed a cutting bed for the reason that the stock is supported upon this member which receives the thrust of the die 13 used in cutting out blanks from the stock. Inasmuch as the pressure surface of the upper presser member is very much less than that of the lower presser member or cutting bed it is necessary to mount the pres ser members for relative movement laterally of eachother, in order that the die may be operated upon when located at widely separated points on the bed. In this case the upper 'presser member is movably mounted, as the post 8 is rotatably carried 1n the bearings 6. In order to reciprocate the upper` presser member toward and from the cutting bed, connections 14 are provided between the post and the main shaft 16 mounted in the base of the machine frame, said connections comprising a pivoted and swiveled link, all as disclosed in the patent referred to above. y
It has been the practice heretofore for the operator to swing the upper pressure member into selected position manually, a handle having been provided on the presser member for this purpose. According to my invention, power'means are provided for carrying out this operation, thus rendering the operation of the machine less fatiguing to the operator, the construction being such, moreover, that the presser member may be brought into its selected position with the same accuracy as when it was positioned by hand. This mechanism for moving the presser member laterally with respect to the cutting bed comprises a shaft 18 which is mounted in bearings 19 and `20 for rotary movement therein and also for endwisel movement. Connected to the end of the shaft 18 is a gear wheel 22 in constant mesh with a second gear 24 mounted on a stub shaft in the same bracket 26 which carries the shaft 18. The gear 24 has a much wider face than that of gear 22 so that the two gears, 22 and 24, remain in mesh in whatever position the shaft may be adjusted. Gear 24 is driven from a pulley 28 fixed to the stub shaft, said pulley being driven in turn by a belt 30 whose other end engages around a pulley 32 fixed to the loose power pulley 34 on the main shaft 16. It will thus be seen that the shaft 18 is driven continuously from the power pulley 34 by the connections above. described. Surrounding the shaft 18 inside of the bearing 19 is a sleeve which carries rotatably thereon two bevel gears 36 and 38. These gears are held constantly in mesh with a bevel gear 40 horizontally positioned between them, said gear 40`being fixedly attached to the upper end of a shaft 42 shown in dotted lines in Fig. 1 as mounted iny an extension of the bracket 26. Mounted uponthe lower end of shaft 42 is a gear wheel 44 which is con stantly in mesh with a large gear 46 secured to the post 8. y Because of the fact that the post is mounted adj ustably infits bearings in order to position the upper presser member adjustably with respect to the cutting bed, and is mounted moreover for vertical reciprocation in the said bearings 6, it follows that one of the gear wheels 44 and 46 must have a much wider face than the other in order thatthe gear wheels may remain in mesh in all positions of adjustment of the post.
In order to drive the gears 36 and 38 selectively there are provided friction clutches 48 and 50 ixedly secured to the shaft 18, the arrangement being such that when the shaft '18 is in a certain position, hereinafter designated as its neutral position, neither of the friction clutches is engaged with its corresponding bevel gear. When neither clutch is engaged with its respective gear, the presser member is stationary. If, however, the shaft 18 be moved to the right in Fig. 2, the friction clutch 50 will engage the bevel gear 36 `thus causing` the horizontal gear 40 to be revolved in one direction to turn the post and the presser member 10 laterally with respect to the cutting bed whereas with the shaft 18 shifted to the left in Fig. 2 the other friction clutch 48 will be engaged with its bevel gear 38 to cause turning of the presser member v10 in the opposite direction. Shifting of the shaft 18 axially is provided for bv means of a `member 52 having a bifurcated arm 54 carrying rollers 56 which engage in a circular groove in a collar 60 fixed to the shaft 18. As shown in Fig. 1, the bracket 26 has an extension toward the front of the` machine which carries a vertical shaft 62 at the upper end of which member 52 is fixedly secured. On the lower end of this same shaft there is fixedly attached a member 64-l1av ing connected therewith a bell-crank 66 provided with a handle 68. It is obvious that movement of the handle 68 to the right or left in Fig. 2 will result in a shifting of the shaft 18 in a direction axially thereofV so as to cause the engagement of one of the friction clutches with its corresponding gear wheel to cause the swinging of the presser member in the desired direction. The member 52 has a second arm 70 extending forf wardly into a space in an upward extension of the forward end of the bracket 26. Bearing upon each side of the forward end of the arm are two vsprings' 72 which can be adjustably tensioned by screw threaded members 74:, the said springs exerting just suflicient pressure on the arm -TO-to maintain the shaft 18 in neutral position. With the shaft 18 in neutral position, the presser member l0 may be moved by hand without the intervention of the power means described above. An yadvantage of the friction type of clutch in the operating mechanism just' described resides in the fact that it maybe used as a brake. Thus .the presser memberfunder motion in a direction toward or from operative position may not only be instantaneously disconnected from the power means which is giving it motion but may be promptly checked by shifting-'to the other clutch which, as stated, will act as a brake. l# oreover, the. cone type of .friction clutch permits of a gradual lor rapid application of the brake and hence the operator'may feel safe in causing the presser member to move as rapidly as he desires since it vmay be stopped in the desired .location by the application of the brake, which may be either of the friction clutches 48 and 50.
The handle 68 hasY another function than that described above, namely, that ofthrowing the machine into Operation in order to cause a reciprocation of the pressure member to apply pressure to the diein cutting out blanks. 'from the stock. The structure provided for the purpose of carrying out this operation comprises'thebell-crank 66, which is pivoted to member Gtfor movement in a vertical pla-ne 'and is provided with an upright arm connected by a rod T6 with an arm 78 fixedly secured to a horizontally extending rod 8O having at its other end a second arm 82 extending from the rod practically 'at a right angle to the arm T8. The handle 68 is maintained in its raised or normal position bya light spring 8l surrounding rod 8O and bearing` against arm 78. Connected to the arm 82 is a. rod-84s the lower end of which operates the clutch control mechanism on `he main shaft of the machine, said clutch mechanism comprising a clutch of the onerevolution vnon-repeating typ Hence, when the handlek 68 is depressed the clutch mechanism will be operatedeto connect the power pulley 8i to the shaft 16 to cause a single reciprocation of Vthe upper presser member lO. v
forwardly extending arm 86`of the bracket 26 carries a plate 88 which is slotted. the edges of the slot being beveled to prelent inwardly slanting surfafeey 96. Carried by the arm 66 lof the'hell-crank there is a member 92 having a wedge shaped end,
the obliquely directed 'surfacesf94 of which are designed to engage selectively with one or the other ofthe slanting surfaces on the slotted plate, the arrangement being ysuch that on depression 0f the handle 68 the samel will be caused to move to such a position by the engagement of the surfaces aforesaid that the'shaft 18 will be shifted to neutral position. Vere' it not for this construction, the operator would have t0 make a conscious effort to move the shaft to neutral position when he had brought the presser member directly over the selected position for the die on the cutting bedso that the lateral movement of the' said presser member might be terminated, and'then by a distinct movement of the handle 68 depress the same to cause the pressure-applying operation of the presser member. By the construction shown the operator moves the handle 68 laterally to cause'the power means to move the pressure member over the selected position on the cutting bed and when the member has arrived at this position he immediately depresses the handle, whereupon the presser member is caused to de scend in its pressure-applying operation, a brake member 96 being depended upon to terminate the Vlateral movement of the presser member so that the die is forced by a direct -blowf through the work. For a complete disclosure of the brake mechanism indicated at 96 referenceshould be had t0 the patent to Harrison H. Eaton, No. 1,064,757,
granted October 3, 1911, it being understood that the springs, shown in connection with the brake mechanism,whirh operate to return the presser member to one Yside of the bed, are operative in the present construction.
The manner 0f using this machine will be Y upon material to be Icut intoV blanks. lVhen Y a die has been placed, the operator grasp@A the handle 68 and moves 1t to the left in Fig. 2 to cause the power means to move thel presser member lOover the die in its selected position. lV hen the pressure member arrives over the die, the operator immediately depresses the handle thereby causing the pressure-applying,movement of the presser member. Obviously'the handle 68 constitutes a single means for Vcontrolling` the lateral and the pressure-applying movementsof the presser member. It will be observed, moreover. that the presser member is at all times underthe control of the operator. After the pressure member rises from its operative stroke, the operator moves handle 68 to the right to cause the power means means may start the presser member from` rest and cause it to be moved only a portion of the Way to operative position and then be disconnected, thus permitting the presser member to continue in motion under its acquired momentum and under the manual control of the operator. From this viewpoint an important feature ot the invention comprises the provision of means for overcoming the inertia `of the movable presser' member in starting it from a position ofrest to move ittoward or :from operative position.

a work supporting bed, a presser member movable toward and from the bed in pressure applying operations and also laterally over the bed into and out of selected operative position, power means for causing lateral movement of the presser member, a manually operable member for controlling said power means, and means for causing disconnection of the power means from the presser member upon movement of the manually operable member in a given direction.
73. In a machine of the class described, a work supporting bed, a presser member movable laterally into and out of various operative positions determinable by the operator and also reciprocable toward and from the bed to effect a pressing operation, and mechanism operative to apply suicient force to the movable presser member to overcome its inertia when it is at rest and move it in the desired direction over the bed, the const ruction and arrangement being such that the presser member is continuously under the control of the operator so that the movement of the member to selected operative position may be completed under direct manual control if so desired.
74. In a machine of the class described, a work supporting bed, a presser member movable laterally or" the bed and also toward and from the bed in pressure applying operations, and mechanism, comprising a manually operable member, operatively connected with the presser member for moving it laterally of the bed, said manually operable member having a position of rest in which it is yieldingly maintained.
75. In a machine of the class described, a work support-ing bed, a presser member movable laterally of the bed and also toward and from the bed `in pressure applying operations, mechanism, comprising a manually operable member, operatively connected with the presser member i'or moving it laterally of the bed, and spring means for yieldingly retaining the manually operable member in its normal position of rest.
76. In a machine of the class described, a work supporting bed, a presser member movable laterally over the bed and also to-V ward and from the bed in pressure applying operations, mechanism operatively connectl ed to the presser member for moving the same laterally of the bed, and a manually operable member movable in a given direction for controlling said mechanism and so arranged as to be operatively disconnectable from said mechanism upon limited movement in the reverse direction.
77. A machine of the class described comprising presser members arranged for relative swinging movements in amounts decomprising a manually operable member,
constructed and arranged t0 be operative to overcome the inertia of the movable presser member in starting it from rest and to impart movement to it in the desired direction and to permit the presser member to complete its movement to operative position under its acquired momentum and the direct manual control of the operator.
79. In a machine of the class described, presser members relatively movable toward and from each other in pressure applying operations and also relatively movable laterally of each other into and out of operative relation,'power means for causing relative lateral movements of the presser members, and means for checking relative lateral movement of the presser members. i
In testimony whereof I have signed my name to this specification.
