The guide A for the wire-bender or staple-forming plunger is of rectangular cross-section and has its bottom wall and side walls formed by providing a comparatively large groove in the forwardly and downwardly inclined top portion of the casting A as will be clearly understood from Figs. 1 and 13. The portion of the casting A in which the groove is thus formed is provided with lateral flanges 22. The upper wall of the guide is afforded by a detachable inclined top-plate 23 which is secured to the flanges 22 by cap-screws 24. The plate 23 comprises a small casting whose lower front portion is provided with a central longitudinal embossment 25, which affords a chutesection having an inclined top-wall 25 which is provided with alongitudinal groove 52 in which the shank of the button can slide as the button, after passing the escapement A, gravitates to a socket in the upper end of the staple-former D, which normall occupies an elevated position which enables the wire to be fed through the eye of the button. The chute-section 25 thus provided tapers to substantially a knife edge at the lower front end, as clearly shown in Fig. 17. The slot 25", at its lower end, intercepts a slot 25 formed in the front edge of a thin steel insert-strip 25, which forms the final support and guide for the button as it. passes to the former D. The bore or guide for the former D is perpendicular to the inclined guide A and disposed below the lower end of the guide A5. The member 25 is thus perpendicular to the former D and lies just above the inclined plane of the upper end of the former D. The chute-section 25, as will be understood from Fig. 9, virtually forms a downward extension of the detachable button-chute E. The top-plate casting 23 has provided integrally with its rear portion a bracket 26 (Fig. 7 which carries a yoke 27 serving as a sup port for the chute E and which is equipped also with a spring-pressed pawl 28 which serves in securing the interchangeable button-chute E in place,,as shown in Fig. 2.
. The button escapement A (Figs. 3, 5, 12 and 13) comprises a housing 29 formed in tegrally with the plate 23; a pair of spring depressed, cam-actuated plunger- s 30 and 31 contained in bores with which the housing 29 is provided, said bores intercepting the guide in which the staple forming plunger B works; laterally-extending escapement fingers 30 and 31 carried respectively by the plungers 30 and 31 and extending over the The form shown is admirably slot 25 as shown in Fig. 13; and a small lever or manual trip 32, by means of which the upper plunger 30 may be lifted, if desired, to permit a button to pass the upper escapement-fingcr and descend to engagement with the lower escapement-finger. The housing 29 is provided with slots 33 through which the escapement-fingers work. The lower ends of the plungers 30 and 31 are provided, respectively, with bevel surfaces 30 and 31 adapted to ride upon the cam surfaces with which the staple-forming plunger B is provided. The lever 32 is confined in a vertical slot with which the housing A is provided; and said lever provided with a slot 32* which loosely receives an extension 30 of the escapement-fingcr 30. The front end of the lever is equipped with a knob or handle. and the rear end is provided with an inturned fulcrum-arm 32 which is adapted to engage a horizontal shoulder or fulcrum bearing 3-} with which the housing 29 is equipped at one side of its rear portion. V hen it is desired to manually elevate the upper feed-finger 30, this may be accomplished by lifting the lever 32 through the medium of the knob at its front end, in which operation the fulcrum-niember 32 will bear upon the shoulder 3t and the lower end of the slot 32 will, engage the pin-extension 30 and lift the plunger 30. The slot 32 permits the automatic actuation of the plunger 30 in the normal operation of the machine.
The plunger 13 which operates as a wirecutter and bend-er is of rectangular crosssection to work freely in the guide A, as will be understood from Figs. 13 to .16, inclusive. It has its lower front end longitudinally slotted, thus affording furcations 35, one of which is provided with a wire shear-edge 35*, as shown in Fig. 16. The inner faces of the furcations are provided with small grooves 35, which accommodate the legs of the staple when the wire is bent about the former D during the descent of the plunger B. The grooves 35 are continued. as shown in Fig. 13, to accommodate the guidefianges of the staple-driving plunger C.
The plunger B, as will be understood from Fig. 12, is provided with a longitudinal groove 36, at the upper and lower ends. of which are beveled surfaces 36 and 36" which serve to actuate the pawls 30 and 31.
To accommodate the staple-driving plunger the upper surface of the plunger ll is provided with a longitudinal guide-slot in which the plunger (l works. The plate 2-3 serves as a top-wall for the plunger C, as well as for the plunger B. The top surfaces of the furcations of the plunger B are recessed or counter link to receive a thin steel disk 37 which is secured in place by screws 37 and which is provided with a longitudidie nal slot 237 (Figs. 11. and 15) adapted to receive the shank of the button, so that the button will be carried thereby to the anvil after the staple-forming operation. The upper surface of the lower front end of the plunger C is suitably recessed or cut away to work beneath the disk 37. The lower front end of the plunger C is provided with a vertical slot 38 to accommodate the shank of the button, and with shallow horizontal recesses 39 adapted to acconnnodate the crown of the staple, the recess 39 registering with the grooves 35)" of the plunger B.
As has been stated, the staple-forming plunger B is actuated by the arm 16 of the rock-lever I, through the medium of the link 17. After the wire-cutting and bending operation has been performed, the plunger G actuated by the am-roller ll carried by the arm 18 in performing the staple-driving and clenching operation. During this operation, yielding pressure is communicated to the plunger B through the medium of a follower it) working against a substantial coil-spring 41 confined in a bore with which the plunger B is provided, as shown in Fig. 11. The follower 4-0 is attached to the staple-driving plunger G by a stud or pin 4-2 adapted to work through a slot 43 i n. the
upper wallof the bore which contains the spring l1. By this expedient, the stapleforming plunger which carries the button to the anvil A is yieldmgly held against the leather or fabric'to which the button is applied.
The plunger-form staple-former D is reciprocable in a forwardly and upwardly inclined guide 4:4 disposed parallel with the face of the anvil A the bore of said guide intercepting the front end of the guide A" which is separated, by a space 46, from the anvil. The staple-former D comprises a depressible post 47 having at its upper end a reduced extension L7. about which the staple is formed; and a substantial coiled spring l8 confined in a bore which extends upwardly from the lower end of the post and is supported by a spring follower or plug l9 carried by a screw or stud 50 which extends transversely across and is supported by the lower end of the guide ll. The tubular lower end of the mcmbergl'l' is provided with a transverse slot 5]. which accommodates the stud 50. The lower end of the member l7 equipped with an external flange T7" which abuts against the lower end of the guide n, which thus serves as a stop limiting the upward movement of the member 47. The arm i of the bell-crank lever G is adapted to bear against the lower end of the member d7 when said, member is in the Wire-feeding and staple-forming position shown in Fig. 9. The upward extension 47 of the staple-former is formed by cutting away the rear upper portion of the post 47 and the side-portions, thus producing the contour shown in Figs. 1a and 15, which correspond to the formof the staple which is formed from the wire 52. The reduced rear surface of the extension 47 is provided with a vertical slot or socket d7, which receives the front leg of the button-eye and whose front wall affords a stop limiting the downward gravitation of the button 53, as indicated in Fig. 17. In
the position shown in Fig. 17, the button is supported partially by the member 25 of the feed-chute 25 and partially by the upper end of the staple-former 4L7. In this position, the wire 52 is fed through the eye 53 of the button, this action occurring at the beginning of the cycle of operations of the machine. The rear upper portion of the post 47 is beveled, as indicated at 54:, the bevel-surface being in position to be en gz'iged by bevel-surfaces 55 with which the fureations 35 of the plunger B are provided at their lower front portions. Flanking the base of the extension in are surfaces 56, over which the lower surfaces of the furcations of the plunger B ride, and thus hold the post at? depressed during the tapledriving operation.
The wire 52 is fed into the machine through a guide 57 which extends through one lateral wall of the plunger-guide A. The length of the staple is regulated by an adjustable stop 58 (Fig. 14) which extends through the opposite wall of the guide A The detachable button-chute E which in a broad sense constitutes a part of the button-feeding means, comprises (Fig. 8) a chute-section 59 adapted to be interposed between the chute-section 25 and the delivery-point of the hopper J, said chute-section being provided with a longitudinal slot 59 adapted to register with the slot 25"; an overhanging guard-bar 60 carried by arms 61, the lower longitudinal edge of said bar being disposed over the slot 59; and a gravityarm carried by the front end of the bar 60, with which it is connected by a pivot 63. The member 62 may be formed by slotting a piece of sheet metal longitudinally at both ends and bending the member to afford a web 62 adapted to rest on the front end of the bar 60 in front of the pivot 63. A stud 64: connects the lower front furcations of the member 62 and has one end provided with a knob 6 f, by means of which the member 62 may be lifted, if de sired. The front ends of the fur-cations of the member 62 are cut away or beveled, as indicated at 62*. The lower extremity of the bar (30 is cut away at its lower edge to permit movement of the eseapementfingers 30 and 31, as indicated in Fig. 11.
The chute-section 59 is equipped with a spring-held pivoted pawl 65 which has an upturned finger 6 adapted to afford a butlOQ ton-stop at the lower end of the slot 59, a shown in Fig. 8. The front end of the pawl is adapted to enter a central recess 67 with which the chute-section 25 is provided, thus centering the button-chute E when it is applied to the machine. When so applied, a projection 68 at the rear end of the pawl engages a bearing 69 on the arm 26, thus depressing the front end of the pawl and removing the stop 66 from the channel through which the buttons gravitate. The lower end of the member 59 is provided with a half circular bearing 69 adapted to engage a laterally-extending stud 7 0 carried by the chute-section 25. The upper end of the member 59 is provided with a half circular bearing 71 which is slotted and adapted to interlockingly engage a central disk 72 and lateral studs 72 carried thereby, with which the hopper J is equipped immediately below the front end of its discharge-slot. In applying the but ton-chute E, the lower end is first brought into proper engagement with its bearings, and the rear end of the button-chute is then swung back until the member 59 rests in the yoke 27, after which the hopper is swung forward about the pivot I-I until the disk 72 and studs 72 engage the slotted bearing 71.
The substitute feed-chute E is constructed essentially like the button-chute E, but is adapted for use when the hopper J is in disuse. The button-chute E is shown as of greater length than the button-chute E. The mode of attachment at the lower end is the same as has been described. No means of attachment to the hopper is provided at the rear upper end. The member 59*, which corresponds with the member 59, is provided at its lower side with a notch or bearing 59 adapted to be engaged by the pawl 28. It will be noted that the pawl or detent 28 has a' double bevel at its lower end, which enables the button-chute E to be snapped into place or removed, when desired.
The lower end .of the main actuating plunger or connecting-rod F is pivotally joined to the foot-leverF, as shown in F ig 6. The foot-lever is held normally elevated by a heavy coil-spring 73. As has been stated, the upper end of the connecting-rod F has stud-and-slot connections 3 with the arm 2 of the rock-lever G which the connecting-rod F actuates. The connections 3 comprise a laterally-projecting stud on the front end of the arm 9 and a vertical slot in the inner side of the upper portion of the connectingrod F, as will be understood clearly from Figs. 7 and 10.
The rock-lever G, as has been stated, is carried by an arm or bearing 1, with which the frame-member A is equipped at its rear P i-be t it is moun d to turn 9 a b l or shaft 74.- (Fig. 10) and is confined between a tension-spring 75 on one end of said bolt and the bearing 1. The pivot and slot connection between the arm or elbow 6 of the member G and the link 8 comprises a stud or screw carried by the slotted elbow 6 and a slot extending longitudinally of the link 8, as will be understood from Figs. 5 and 7.
In the normal position of the parts, the
roller of the cam-arm 5 is substantially in engagement with the cam-arm 15 of the rock-lever I. As has been stated, the first action in the cycle of operations of the machine is that of feeding the wire through the medium of the mechanism L, this action being caused by the first movement of the connecting-rod F in a manner to be presently described. During the wire-feeding action, the rock-lever Gr remains idle, owing to the stud-and-slot connection 3. Then the member G is rotated, bringing the cam-arm 5 into action and turning the rock-lever I through the medium of the cam-arm 15, the rock-shaft H in the meantime remaining idle, owing to the pin-and-slot connection 7. Subsequently, the rock-shaft H is rotated, and through the medium of the rock-lever H, which is rigid with the shaft H, the staple-driving plunger C is caused to perform its working stroke. The rock-shaft H is returned to its normal position by the spring 7 3 connected with the foot-lever F; and the rock-lever I is returned to its normal position by a laterally-extending stop 76 (Fig. 7) which engages a shoulder 77 with which the cam-arm 15 is equipped, it being noted that when the staple-driving plunger C is forced downwardly to the limit of its stroke, the stop or projection 76 of the rocklever H moves away from the shoulder 77 of the rock-lever I.
I11 the preferred construction, the hopper J comprises a side-member 78 (Fig. 8) carried by the pivot-arm 18: an intermediate vertical plate 79 carried by the pivot-arn'i 19; a detachable hopper-section 80 connected with the intermediate plate by screws 81; and a top 82 joined by pivots 83 to the sidemember 78. The members 78 and 79 afford a housing 84 for an endless conveyer-chain. The members 78 and 79 are secured together by screws 85 (Fig. 9).
The buttonfeeding mechanism J comprises a shaft 86 which is actuated by ratchet-devices through the medium of the links H and H; a conveyer-chain 87 confined in the housing 84 and supported by wheels mounted on shafts 88 and 89; a but ton-elevating wheel 90 fixedly secured to the inner end of the shaft 86; a pair of ratchetdisks 91 and 92 mounted on the projecting end of the shaft 86 so as to communicate motion to said shaft; rings or sleeves 91 and embracing said disks; clutch rollers 91 and 92 confined between the inner surfaces of the rings and said disks; and bevel surfaces 91 and 92 afiiorded by recesses with which the disks 91 and 92 are provided, respectively, the rings 91 and 92 being equipped, respectively, with arms 91 and 92 connected with the links H and H. The arrangement is such the when the arm H swings upwardly during the depression of the foot-lever, thus lifting the links H and H the ring 92 will turn the shaft 80, while the ring 91 moves idly; and in the return stroke, the ring 91 will continue the turning movement of the shaft 86, while the ring 92 works idly.
The stop mechanism K comprises (Figs. 2, 1S and 21) a gear 93 (which forms also a part of the button-feeding mechanism J) mounted on the shaft 86 to turn with the disks 91 and 92; a sleeve or tubular rockshaft 91: journaled on the shaft 86 and adapted to be rotated through the medium of the link K when the hopper is swung to the intermediate position shown in full lines in Fig. 2; a cam 95 carried by the sleeve 941:; and a springheld detent or pawl 96 carried by a pivot 97 mounted on the hopper and having formed integrally therewith a cam arm 98 which engages the cam 95. then the hopper is turned to the intermediate position shown in Fig. 2, the sleeve 94 is rotated to move the cam 95 from engagement with the cam-arm 98, thereby permitting the detent 96 to engage the teeth of the gearwheel 93, so that the mechanism J will not be turned when the machine is operated, assuming the hopper to be in the intermediate position.
The gear 93, as shown in Fig. 21, is provided with a sleeve 93, upon which the disks 91 and 92 are mounted. Intel-posed between the disks which are provided with suitable sockets are coil-springs 99 which tend to force the disks apart. The disks are confined between the gear 93 and a disk or knob 100 which have threaded connection with the shaft 86. Fiber disks 101 are interposed between the disk 91 and the member 100 and between the disk 92 and the gear 93, and the construction is such that the desired amount of friction can be created to communicate ample power to turn the shaft 86 in the normal working of the machine; but should the machine become clogged in the feeding of the buttons, a slippage will occur, thereby obviating danger of breakage.
The members 78 and 79 which form the housing for the conveyer-chain are provided, as will be understood from Figs. 18 and .19, with ledges which afford a slotted horizontal button run-way 102 through the slot 103 of which work the button-convey ing arms 101 with which alternate links of the chain 87 are provided. The walls of the slot 103 are beveled, as indicated at 105, to facilitate the lodgment of the buttons therein as they are elevated and dumped by the teeth 90 of the wheel 90. The wheel 90 works within a circumferential wall 100 with which the member 79 of the hopper is provided; and the bottom of the hoppermember is inclined so that the buttons will gravitate between the teeth at the lower portion of the wheel. The teeth have their front surfaces beveled or undercut toward the plate 7 9; and the bottoms of the slots between the teeth also slope toward the plate 79, so that buttons will be carried upwardly, as indicated in Fig. 5, and discharged into the slot 103. At the front end of the slot, the slot is contracted, as indicated at 108, and formed with vertical walls adapted to accommodate only the shanks of the buttons. As shown in Figs. 5 and 19, the hoppermember 78 is equipped with a wiper-s ning 103 which is adapted to dislodge improperly positioned buttons, or any surplus of buttons, and cause them to slide back through a passage 103, having an inclined wall, into the interior of the hopper. The passage 103 is formed in front of the circumferential wall 106 within which the button-elevating wheel rotates. This fetture of in'i irovement is adapted to facilitate the return of improperly lodged buttons or any surplus of buttons to the bottom of the hopper, without interfering with the operation of the wheel 90. The chute or run-way 102 terminates slightly in front of the front end of the hopper and is curved to join the upper end of the detachable button-chute. so that a continuous run-way for the butions will be afforded. As will. be understood from Figs. 1, 9 and 19, motion is communicated from the gear-wheel 93 through an idler 10'? mounted on a stub-shaft 107 to the pinion 68 mounted on the shaft 89 which actuates the c-onveyer-chain.
As has been stated, the piVOt-arm 18 of the hopper is equipped with an extension 18, which co-acts with a spring-held plunger or detent 18 The spring-pressed plunger 18 is mounted in a guide 108 projecting later ally from the frame-member A the tension of the spring of said plunger being adjustable by means of a screw 109 which extends through a boss 110. The rear upper end of the plunger or detent 1S is equipped with a cam-roller 111 which is adapted to engage either one of two curved recesses 112, 11.3 with which the arm or segment 18 -is provided at its lower edge. The segment-1S also affords a curved surface 114 upon which the roller 111 may ride when the hopper is swung to the position indicated by dotted lines in Fig. 2. The recess 112 corresponds with the upright position of the hopper; and the recess 113 corresponds with the intermediate position of the hopper.
The wire-feeding mechanism L, as has been stated, is mounted on the bracket 21,
a similar pinion formed integrally with a feed-roll 118 journaledon the front end of a bar or shaft 119 whose rear end is connected with the bracket 21 by a pivot 120. The upper feed-roll is yieldingly held in a depressed position by a spring 121, but may be lifted bya rock-shaft or eccentric 122 equipped with a handle 123. A pawlcarry ing yoke 124 is journaled on the shaft 115. this yoke being equipped With a pawl 125 adapted to actuate the pinion 117, in the direction indicated by the arrow in Fig. 10 when the yoke 124 is swung outwardly a way from the connecting-rod F. In the return movement, the pawl works idly over the pinion. The yoke 124 is equipped with a short arm in which is journaled a camroller 126 adapted to engage a semi circular cam-recess 127 formed in the outer side of the connecting-rod F. The rear end of the shaft 115 is equipped with a coil-spring 12%, one end of which is secured to the shaft and the other end of which is connected, by a screw 124. to the yoke 12%. The shaft 115 has a threaded portion equipped with a locknut 128 between which and the shoulder on the shaft 115 isconfined alug of the bracket 121 through which the shaft 115 extends. The shaft 115 may be turned to adjust the tension of the spring 124% and then secured in adjusted position by the lock-nut 128. The spring 124: tends to return the feedroll actuating-yoke 124: to the position shown in Fig 10, in which the cam-roll 126 engages the cam-recess127. When the plunger F startson the down st'roke,, the cam recess 127 causes the member 124: to swing out wardly, thereby actuating the feed-rolls through the medium of the pawl 125. After the wire is fed. the cam-roll 127 works on the outer vertical surface of the connectingrod F above the recess 127. Thus, the member 1241 is held in the outwardly-swung position until the connecting-rod F rises, when the spring 12 1 forces the cam-roller into engagement with the cam-recess 127. This operation. is effected notwithstanding the fact that the upper end of the connectingrod F is swung forwardly and rearwardli somewhat, owing to its connection with the rock-lever G whichturns about the pivot 7%. In the wire-feeding operation, the movement of the rock-member, or yoke, 124i, is sutlicient to feed the wire somewhat more than the required distance,it being understood that the feed-rolls will slip on the wire after the end of the wire encounters the stop 58 shown in Fig. '14-.
The operation is as follows:
The operator places the leather or fabric 129 (Fig. 16) back of the anvil A, and depresses the treadle F, thereby lowering the connecting-rod F. During the initial movement of the connecting-rod, the wire-feeding mechanism L is actuated through the medium of the cam-roller 126. which is normally in engagement with. the recess 127, as shown in Fig. Atthe beginning of the cycle of operations, a button is in the wirefeeding position shown in Figs. 11 and 17, having been allowed to descend to that position, owing to the lifting of the lower escapement-finger 81 during the return stroke of the staple-forn'iing plunger B. After the wire-feeding operation, the upper end of the slot in the connecting-rod F (pinand-slot connection 3) engages the pin carried by the extremity of the arm 2, thereby actuating the rock-lever G, which, through the medium of the cam-arm 5, actuat-es the rock-lever I by engagement with the camarm 15, thereby actuating the wire-severing and staple-bending plunger B. After the wire is severed, the link 8 is actuated through the medium of the arm 6 of the rock-lever G, thereby turning the rock-lever, composed of the rock-shaft H and the arms which are fixedly mounted, thereon, thus carrying the cam-roller 1% against the rear end of the staple-driving plunger 0 and actuating the plunger C, as will be understood from a comparison of Figs. 7 and 9. As the plunger C descends. the tension on the spring 41 (Fig. 11) increases, and the plunger 13 is thus picked up and actuated by the plunger C during the remainder of the working stroke, the rock-lever I being carried along by the link 17 it being noted that the camarm 5 ceases to engage the cam-arm 15. As the plunger B descends, it bends the wire about the extension 17 of the staple-former, the crowno-f the staple remaining in engagement with the eye of the button, while the legs of the staple are held in the grooves ofthe furcations 35. The slotted front portion of the disk 37 carried by the furcations of the plunger B passes beneath the button. as the plunger B descends, and the beveled surfaces of the plunger engage the be eled surface 54; of the former 47, thus depressing the former. The plunger C gains upon the-plunger B during the descent of the plungers and drives and clenches the staple in the manner shown in Fig. 16.
hen the pressure upon the foot-lever is relievedfthe foot-lever is returned by the spring 7 3, and the parts are returned to their normal position. During both the working stroke and the return stroke of the plunger-s B and C, the shaft 86 of the button-feeding mechanism J is rotated in the direction indicated by the arrow in Fig. 1, the link H and clutch-ring 92" serving in the actuation of the shaft during the working stroke of the pl u-ngers B and C, and the link H and the clutch-ring 91 serving in such actuation during the return stroke. of the pluugers. The buttons are lifted to the button-runway of the hopper by the wheel 90, and such buttons as are properly lodged in the runway are carried forward by the endless button-couveyer 87, being discharged from the front end 102 of the run-way of the hopper into the upper end of the inclined buttonchute E, which, it will be understood, is kept filled, or partially filled, with buttons by the operation of the button-feeding mechanism J. During the working stroke of escapemcu t-finger 30 thus permitting a but ton to descend into engagement with the lower escapement-finger 81. In the return stroke of the plunger B, the finger 31 is lifted through the medium of said plunger, thereby permitting the lowermost button to descend. to the wire-feeding position shown in Fig. 17.
It will be noted that the escapelnent-finare associated with the permanentlyattached, though removable, button-chute section 25 so that the button-chute E can be removed without disturbing the escapement; also, that the buttons 5 escend by gravity directly to the wire-feeding position, the
passage vot' the buttons being controlled by the escapeinent; also that the stapletormer 47 is i'iormally in the elevated position which corresponds with the wire-feeding position, so that the button is held by the staple- :t'ormer during the wire-feeding operation, the button beingalso steadied or prevented from toppling over by the gravity pawl, or buttoinpresser 62, from beneath which the button will slide freely, nevertheless, when the button starts to move to the anvil.
When desired, the hopper J may be swung to the intermediate position shown in full lines in Fig. 2, and the button-chute and magazine E may be substituted for the button-chute and magazine F. In such position of the hopper, the button-feeding mechanism will be locked against operation by the pawl 96, which is thrown into engagement with the gear 93 through the medium of the link K when the hopper is swung to the intermediate position. In such position of the hopper, the machine may be operated in th manner already described, except that the buttonfeeding mechanism of the hopper remains in disuse. hen desired, the hopper J may be thrown to the position inclicated by the dotted lines in Fig. 2 to enable the contents to be discharged.
The machine described is simple and may be cheaply manufactured, notwithstanding it is somewhat difficult of illustration. It possesses great certainty of operation, due largely to the improved manner in which the staple-bending plunger, the staple- .t'ormer. and the sta nle-drivin plun 'er co t) to been given for clearness of understanding only, and no unnecessary limitation should be understood therefrom, but the appended claims should be construed as broadly as permissible in view of the prior art.
