Description
from the perpendicular with respect to the post means under ~he control of the guide means. It is preferred to resiliently hold the ~nife in the holde~ so that knife clatter is obviated. The movable ~nife is removably mounted to th~
holder so that a worn knife can be readily shaxpened or raplaced.
It is another feature of the invention to pro~ide a pinning machine of the type having an anvil and a cooperable plunger with an arrangement by which an operator can quickly o change over the machine to pin tags to various thicknesses of merchandise. This is accomplished by changing the length of the plunger so that whsn the plunger is actuated the amoun of clearance between th~ plunger and the anvil (when the plunger and the anvil are in comple,te cooperation) can be varied. In the preferred arrangement the operator simply rotates one part of the plunger through 360 degrees to either lengthen or shorten the plunger. If for example the length ~.
of the plunger is set to pin tags to thin merchandise such as delicate lingerie and it is now desirecl to pin tags to thick merchandise such as heavy denim jeans, then the plunger length should be ~hortened by rotating one of the parts of the plunger relative to another of the plunger parts, and vice versa. It is preferred that the plunger parts be threadably adjustably secured to each other so that rotation of the parts relative to each other results in lengthening or shortening of the plunger~
It is also a feature that the plunger be lengthened or shortened in stages. As an operator becomes familiar with the adjustment from the perpendicular with respect ~o the post mea~s under the control of the guide means7 It is preferr~d to resiliently hold the knife in the holde~ so that knife clatter is obviated. The movable knife is removably mounted to the holder 50 that a worn knife can b~ readily sharpened or replaced~
It is another feature of the invention to pro~ide a pinning machine of the type having an anvil and a cooperable plunger with an arrangement by which an operator can quic~ly lo change over the machine to pin tags ~o various thioknesses of mexchandise.

The bracket 69 also has an arm 70 with a pair of holes 71 which receive threaded fasteners 72 threadably received in ~ threaded holes 77 in hody 78 of the holder 54. The holes 67 ; are axially aligned with ~he posts 60. There i5 a relatively close fit between the posts 60 and the holes 67 SQ that when the bracket 69 is in place both end portions of the posts 60 are secured. The holes 61 are also axially aligned with the posts 60 but are suffi.ciently large in dimension to enable the knife 62 to skew relative to the posts 60 as shown exaggeratedly in FIGURE 4. The knife 62 is shown : to be received in a gap 79 betwe~n a spaced-apart pair of knives 80 and 81. The tang or extension 64 is in guided relationship with the end faces of the knife so that the knife 62 is always guidad by the tang 64 in alig~ment with the gap 79. ~he 0-ri~gs 66 resiliently yield to allow the guide 64 to control the position of the knife 62~ As also shown in FIGURE 4 the l~g portion 68 is parallel to wall ; ~2 of the holder 54, and the pcsts 60 axe shown to be perpen-dicular to the leg portion 68. The 0-xings 66 are shown to be under different states of compression in FIGURE 4~ It is readily apparent that the knife 62 can ca~t with respect ~o the perpendicular relative to the posts 60, in that the knife 62 is loosely or floatingly mounted on the posts 60., The holes 61 in the shank por~ion 65 of the knife 62 can be of any desired shape for example they can be elongated slots/ so long a~ the knife 62 is permitted to function in ~he manner in~ica~ed above. By an alternative construction : (not shown) the knife 62 can be provided wi~h integrally formed posts or studs which can be floatingly or loosely received in the holder to accomplish the same purpose or the knife 62 can be mounted in the holder in any suitable manner to accomplish the foregoing coaction. As is preferred the knife 62 is a blanking knife which means ~hat the knife ha~ opposed edges 62a and 62b which cooperate respectfully with edges 80a and 81a of the respective knivP~ 80 and 81, although the invention is not limited to the use of a blanking knife. The web W of tags T is provided with lands L disposed between the ends of laterally aligned 910ts S. The cooperating knives 62, 80 and 81 sever lands L between la~eral aligned slots S to provide recta~gularly-shaped blanks or chad so that the severed tag is rectangular and can be readily ~ed by the feed finger 46. In the event the knife 62 encounters undue resistance the spring 59 will yield as indicated in FIGURE 6 to prevent damage to the machine 20.

The part 122 also includes compression spring 134 which beaxs at one end of the plunger member 125 and at the other end against the connector 127. Th~ spring 134 is adapted to yield when khe plunger 36 encounters undue resistance at the pinning lo ~one Z. ~he tube 124, ~he plunger member 125, ~he pin 126, the connector 127, the pin 129 and the spring 134 can be considered to be one part or suhassembly in that the part 122 is rotatable as unit relative to the part 123. The paxt 123 is shown to include a connector 135 having a clevis or clevis portion 136, a threaded portion 137 threadably received in the threaded bore 128, and a detent 138 threadably received by the connector 135. The dPtent 138 is shown in detail in FIGURE 12. The detent 138 i!3 threadably recei~ed in a through hole 139 and is held in place by a plastic ~, 20 locking member 140. The detent 138 includes a cavity or recess 141 for receiving a compression spring 142, a dish-shaped washer 143 and a ball 14~. The ball 144 is shown tv cooperate with a longitudinally extending groove 145 in the connector 127. The detent 138 and the groove 145 are so positioned that guide groove 146 in the plunger member 125 is correctly ori~nted with respect to pin driver 50 when ball 144 cooperates with the groove 145. In the event the operator desir~s to change the ~ength of the plunger 36 for pinning a ta~ T to a different thickness of merchandise, the operator .
gxasps the portion of the plunger 36 which extends above th~ barrel portion 120 and rotates it ~hrough 360 degrees or through a multiple of 360 degrees in either one di~ection or in the opposite direc tion to either len~then or shorten the plunger 36. ~hen as for example a tag T i5 to be pinned to thick merchandise the plunger 36 is rotated in the direction which will shorten the pl~nger 36. In so doing the entire part 122 rotates relative to the part 123. The shortened plunger 36 :~
will ~ow rise to a final but lowex level relative to the lo anvil 37~
