ERICH F. W. RICHTER, OF. GERMANY, .ASSIGNOR TO.THE TABULATING MA- CHINE COMPANY, OF ENDICOTT, NEW YORK, A CORPORATION F NEW JERSEY AU'roMA'rrc CARD EJEcToR Application led February 8, 1927, Serial No. 166,626, and in Germany October 16, 1926. l

This invention relates to record handling machines and more particularly to a device for automatically ejecting records from the machine after they have been operated upon by it. The invention is particularly adapted to card punching machines from which the cards are ordinarily manually removed from for removing cards from a card handling machine.

A more specic object is to provide for. automatically ejecting cards from the ma! chine.

A further object [of the-invention is to provide an automatic card ejector for a card handling machine Awhich is operated by the machine immediately upon completion of an operation upon a card.

A Jfurther object of the invention is to provide an automatic card ejector for a card handling machine in which cards are carried on a card carriage and in which the card carriage trips the ejector at the completion of its card carrying movement.

A further object of the invention is to provide an automatic card ejector for a card handling machine which will be automatically set for an ejecting operation when a card is inserted into the operating portion of the machine.

A further object of the invention is to proi vide an automatic card ejector for a card handling machinein which cards are carried by a card carriage and in which the yejector will be automatically set for an ejecting operation When the carriage is moved into po' s sitlon t-o receive a card.

Other objects and advantages of my` invention Will be obvious from the following particular description embodying the invention and of the accompanying-drawings in which:

Fig. 6 is a side partly sectional vie-W of the punching section o the machine; f gig. 7 is a detail of the escapement means, an

Fig. 8 is a plan'view ofI a part of the punchj ing section. For the purpose of clearly disclosing my invention it has been shown as applied to a duplicating punch of the type shown in the copending application of F. Lee and B. Phillips, Serial No. 34,516, led June 3, 192,5. The operation of the punch is fully ex, plained in that application and will be eX- plained in the present case only in suicient detail to define its relation to the ejector mechanism.' Referring to Fig. 1 it will be understood that the cards may be fed one at a time into the punching section 33 by moving the handle 2 to the left. This opera-f' tion moves the card carriage 16 (Fig. 2) to the rightand picks the bottom card from the stack and deposits it on the carriage in posi-4 tion to have its first column punched. If the control ofthe punches is manual, the operator depreesV the desired key which through a bell lever 41 (Fig. 6) advances an interposer 42 against a spring 43 over the 4h ead of a punch 44 normally held by a spring 45 in its uppermost position. Through means not `essential to an understanding of the present invention and fullydescribed in the copending application hereinbefore mentioned, the interposer 42 upon advancing closes a circuit through punch magnet 46 which attracts armature 47 to rock lever 48- and moves link 49 downwardly. The upper end of the latter is pivoted to a bail or ham- .mer 50 and rocks the latter counterclockwise (as viewed in Fig. 6) about its pivot 51.

ever be engaged on the upper edge by the bail 55 and rocks it counterclockwise.

nose 53 and will be depressed. thereby thus depressing the punch 44 and causing punching. During downward movement of the interposer the bottom edge thereof engages a The bail 55 is fixed toa`shaft 56 (see Figs. 6 and 8) which carries at one end an arm 57 and an oppositely extending arm 58 (see Figs. 7 and 8)'. Arm 57 has av pin 59 fixed thereto which is loosely positioned in a hole 60 in a feed pawl 61. Arm 58 has a pin 62 seated in a -notch at the forward end of a holding pawl 63 (see Fig. 7). Normally the pawl 61 is in engagement with a tooth on the escapement rack 64 which is provided at the bottom with teeth 65 meshing with gear 66 carried by the usual spring drum initially tensioned when the carriage was moved to the right to receive a. new card. lVhen the `interposer rocks bail 55 and shaft 56during a punching operation, the pin 60 moves upwardly and the pin 62 downwardly. The pawl 61 is thereby lifted from the escapement rack and moved by a spring 67 to the left (as viewed in Fig. 7 )until the nose of the pawl rests on and slightly past the top of the next tooth. l-Vhile this occurs, the pawl 63 has been moved down by pin 62 until it engages the escapement rack. The rack is thereby held from moving during punching. After the hammer 50 has been rocked to effect the downward Inovement of the interposer and associated punch, the circuit through magnet 46 is broken and armature 47 is released thereby returning the parts to initial position. The interposer rises and permits bail 55 and shaft 56 to return to initial position. Pin 60 thereupon moves downwardly and pin 62 upwardly. The pawl 63 thereupon rises and pawl 6l is allowed to move down, the escapement rack being moved by pinion 66iuntil the trough of the next tooth is engaged by the nose of pawl 61. Thus, each time a punching operation is effected, the rack is permitted to escape one tooth. The rack is rigid with and part of the card carriage 16. Thus, after the first eolumnis punched the carriage automatically moves one 4step tothe left lto bring the card into position to have its second column punched. As each column is punched the step by step feeding movement of the carriage is repeated until finally all the card columns are properly punched and the carriage stands in its extreme position to the left where the punched card may be removed and the handle 2 againnoperated to feed the next card from the bottom of the stack and move the card-carriage to the right into position to receive it.

It has hitherto been necessary to manually remove the card from the card carriage after ,and deposit it in a suitable lreceptacle when the carriage advances the card from the last punching position. The ejector will now be described.

The reverse movement of the carriage 16 is effected by a rod 32 (see Fig. 5). The feed mechanism through which the reverse movement of the carriage is effected does not enter particularly into the present invention and will not be described as its operation is clearly explained in the cepending application above referred to. AIt will be understood, however, that whenever the handle 2 is moved to the left to feed a card and incidentally restore the carriage 16 to its starting position the rod 32 will be likewise moved `to the left. Rod 32 is enclosed in a slotted tube 3 (see Figs; 1 and 5) and when handle 2 is moved to the left rod 32 is pushed against another rod 4 to which is atiixed at its left end a rack 5 coacting with gears 6. Abutting the free end of rack 5 is a spring 7 to which is fixed at its other end a slug 8 slidably mounted in the tube 3. A set screw 6a coacting with slug 8 enables the proper adjustment of the tension on the spring 7. When spring 7 is compressed rack 5 cooperating with gears Grevolves a shaft 9 upon which is mounted the ejector unit 10 (see Fig. 3). This clockwise movement ofthe shaft 9 rocks the ejector unit 10 to the position indicated in Fig. 3. A latch 12 pivoted at 13 and biased by a lOt spring 14 tends to hold the ejector unit in y 'of sufficient length to come into contact with the upper jaw 20 thereby holding the jawsl 18 and 20 apart sufliciently for a card to easily slip between them as long as the ejector unit is latched by the latch 12 as shown in Fig. 3. An arm 23 fixed to the latch member 1'2 carries an adjustable set screw 24 which lies in the path of a discj25 mounted on the card carriage 16 (see Fig. 2). When the last card column is punched the card carriage 16 moves one step further to the left causing the disc 25 to strike agalnst the set screw 24 causing the arm 23 and the attached latch 12 to move against the action of spring 14 whereupon the ejector unit is released and the shaft 9 carrying the ejector unit is rotated through the agency of spring 7 and gears 6 to the cjecting posia hole in the jaw encounters a member 27 and pries the jaws apart against the tension of spring 21 thereby releasing the card llowiig it to fall into the receptacle 28 (see tig. 1
