thatmachine which will automatically remove chips'severed from the tags during the cutting operation `from the vicinity ofthe cutter and the operating parts thereof whichis simple in construction yet positive in operation and which mayeasily be adapted to other: than tag notch-r ing machines wherein .chips are cut fromthe edge yof material and must be moved from the vicinity ofthe cutter to maintain proper operatonoff the machine. v v

Asillustrated herein fthe machine with which the', chip remover isA combined has a cutter, andA l lmeans for effectingmovement of the cutter 'into and out olf-cutting. engagement with-a tag to cut a notch in an edge of the tag by severinga small chip therefrom. In accordance wi-th the foregoing objects of this invention a chip yremoveris associated with-thecutter in a manner to extract eachfchip from its notch as the cutter severs it'from the tag., 'As illustrated the,

Divided and this application March 8, 1950, Serial No. 148,397 i claims. (ci. isi-5o) and. inventories.

chip remover is in the form of a linger carried y by the cutterA` and movable therewith to 'enter1 theltag prior to the cutting operation and thereaftermovable" to a lateral position remote from the: cutter. Lateral movementv of the nger is lrestrained during the approach of thenger and entrance thereof into the tag by a latch, the latch being released to eifect the aforesaid lateral movement to eXtra-ct the severed chip following severance by cutting movement of the cutter. `A manually operated lever serves to effect movement of the cutter for the cutting,A operation and spring means returns the cutter yieldable member is associated with thecutter to engage the tag as the cutter moves into cut-V ting contact therewith and to remain in4 engagement with the tag 'until the cutter has retracted sumciently to clear it. A tag carriageupo'n whichl the tag is placed for movement relativeftogthe cutter is arranged tdreceive the tag"reversed, end for end, so that either 0r both edgesgmay be placed between thek cutter and cutter block.'Av

The, first group on the top marging'as;seen-jin-A Fig.2,` Arepresemas hundred-thousandths, the second group yte'n-thousandth's, and-.the third group thousandths.,. The groups in the vlower margin'v A are marked f respectively hundredths, tens f and number Vis punched in an edge oredges'fof the? tag by cutting through the tag to remove chips' r pods C, (Fig. 5) which are substantially triangular in shape. To illustrate, suppose the number to be recorded is 121-643 (Fig. 3). The first -three numbers 1-2-'7 represent 127 thousand and would be recorded by cutting a notch opposite 1 in the first group (designated 26C), a notch opposite the number 2 in the second group (designated 28C) and a notch opposite the number 7 in the third group '-(designated 30C). The tag would then be reversed, that is, turned end for end and notches corresponding to the numbers 6, 4 and 3' cutinftheopposite Since there is no key having a digitvalue.

edge. of 6 on the machine, this number would be made up by cutting notches opposite theA gures .Ll-and 2. In the same way the number 3 would loeY made up by cutting notches opposite 2 and 1;

The machine 32 for cutting notches in tags' of the type described above is shown in Fig; 1 as comprised essentially of aA cutter head 34, a tag carriage 36 arranged to present an edge of the tagv to the cutter, anda keyboard 3.8Y for selec.- tively positioning the tag-carryingcarriage with respect tothe, cuttergthese being assembledv in operating'v relation to each other, as willappear hereinafter, ona base 40.

When `the lower extremity of the finger. 9.8v comes!l into contact with theu surface of.'thecutterrblockv it will-stop and further.V movement of theheadwill-lift the shoulder I|4v over the :edge .1I I6withv thefresult that the springI I8V tends -to urge the; nger rearwardly with considerable yforce. Rearv ward-movement of the nger. willbe resisted until the cutter penetrates the, tag. orl tags whereupon it snaps rearwardly andv thus extractsthe chip or-chipsfrom their notches.. Toresist thev lateral force of the chip remover and hence displacement of thetags on the cutter block, guides |26 are placed at opposite sides of the cutter in a position to be engaged by the edgesv of the tags which are being notched and to hold them in proper relation to thecutter. While as illustrated the end of the finger enters-one. of the holes 22 vin the edge of thetag, it is apparentl that chips might be extracted from van imperforate tag by surface engagement ofthe nger with the piece to be removed or partial penetration thereof, for example, by sharpening the end of the finger.

To reset the chip remover, the.v link iiwhas sion of the springs 12, the gear will, of course:y

be rotated in a clockwise directionand as the cam surface |24 comes intocontact with the limb |22r it forces the link |52 upwardly and forwardly against the opposition of the spring ||8 until the shoulder ||4 isv reengaged with the stop HB. f n

To prevent the chips C from sticking to the chip remover and returning with it as it is" returned to a relatchedposition, there is provided a stripper which is in the form of a plate |28 fastened to the frame at the base of the turret and which has at its forward edge an upwardly inclined wall |3 in which there is a slot |32 through which the finger 98 passes as it is snapped rearwardly by the spring B. The downwardly inclined surface of the portion |30 strips the chips from the end of the finger 93 and deflects them downwardly into a removable drawer |34 situated in the base of the machine within a housing |36, the top of which is open at |38 to permit the chips to fall into the top of the drawer. A knob (not shown) on one end of the drawer affords means for withdrawing I claim: `l. In a machine for notching an edge of a rtag by cutting a chip therefrom including a cutter block upon which may be placed a tag to be notched, a cutter movable to and from the cutter block to cut through a tag placed on the block, and means for effecting cutting lmovement of the cutter, a` slender finger t mounted. adjacentA to the cutter with anV end thereof close to and slightly in'advance of the cutting edge thereof, said finger being movable with the cutter toward the cutter block for entrance into 'a tag resting on'the block prior to severance of the chip from the tag and thereafter being movable to a position remote from the cutter to extract a chip from its notch and discard it, means for effecting said lateral movement ofthe finger upon termination of the and cutter fast thereto said cutter head being it from the base of the machine to empty it when necessary. A guard |4| is placed above the opening in the housing |36 and extends therefrom upwardly substantially to the under side of the stripper |28 so as to prevent the chips from accidentally being thrown behind the drawer.

The tag-carrying carriage 36 is in the form of a iiat plate |42 arranged to move transversely of the machine relative to the cutter 52 and is moved in one direction by a hand lever |48 fastened to the left end thereof and in the opposite direction by a motor |62 in the form of a clock spring. The operation of the carriage, escapement mechanism for interrupting movement of the carriage to receive cuts in its edges and the key-operated means for controlling the escapement mechanism so that a predetermined composition may be made is ldescribed in detail in my aforesaid pending application. VIt is suiiicient to say thatthe keys are arranged to set up stop elements in the path of escapement mechanism carried'bythe carriage and that upon each operation of the cutter the escapement mechanism is released from engagement with a given stop long enough to permit the carriage to travel to the next stop.

It should be understood that the present disclosure is for the purpose of illustration only and that this invention includes all modifications and equivalents which fall within the scope of the appended claims.

ksituated close cutting movement of the cutter, and a stripper to the path of the finger at opposite sides thereof for intercepting and stripping chips from the finger during its lateral movement.
