(Cl. 164-112) The invention relates to tape punching devices longer slot is shown at I2, this being the length and more particularly to mechanism for punch- ordinarily used for providing a punched “dash”. ing or perforating a tape of the type used with automatic telegraphic transmitting systems. 5 It is an object of the invention to provide a tape punching or perforating device which will be simple in construction but reliable in operation. It is a further object of the invention to prol0 vide improved mechanism for accurately advancing a message tape so that the same may be perforated, It is a further object of the invention to proVide a tape punching machine in which sucoesl5 sive unit perforations in a tape may be combined in such a manner as to provide an improved multiple unit perforation, 30 to operate and which will produce a properly n "o „5 'l' 40 45 tíOn and fOr punching the tape lll, aS referred to above, includes a frame or base portion 20 prefer ably 0f Cast metal» ~ perforated tape, Other objects of the invention will appear from The frame 2!! has centrally disposed at the fear JGllel'eOf an upwardly eXtendlng Standard 2l the speciñcation and claims. Which is cast or otherwise secured to the hori . Tne nature and characteristic features of th invention will be more reacniy understood from vthe following description, taken in connection with the accompanying drawing forming part hereof, in which Fig. l is a plan view illustrating a preferred embodiment of the present invention; Fig. 2 is a vertical sectional view taken longitudinally, and approximately on the line 2_2 of Fig. l; Fig. 3 is a vertical sectional view taken laterally, and approximately on the line 3-3 of Fig. 2; Fig. 4 is a vertical sectional view taken iateraily, and approximately on the line 4_4 of Fig. 2; Fig. 5 is a vertical sectional view taken longitudinally, and approximately on the line 5-5 of Fig, 1; Fig. 6 is a plan view on a somewhat enlarged scale of the tape, it will, of course, be understood that the aesoription and drawing herein contained are iiiustrative merely, and that various modifications and changes may be made in the structure disclosed without departing from the spirit of the invention. 50 Spaces will be uniform. The apparatus comprising the present inven It is also an object of the invention to provide a machine for punching tape which will be easy '3D The length of the slot I2 is slightly less than three times the length of the unit slot I I. A still longer slot is shown at I3, the length thereof being slightly less than five times the length of the unit slot I I. Spaces between the slots are also provided, a Space of unit length being shown at I4, and a lODger Space 0f a plurality Of Spaee units 0f l0 length at I5. The length of the slots and the intervening spaces may be varied in substantially unit lengths with the device of the present invention but the lengths selected by the operator for the slots and l5 Referring more particularly to the drawing, the tape, designated as lil, has slots or perforations of diiîerent predetermined lengths punched therein as hereinafter pointed out. A slot of unit length is shown at II, this being the unit ordi55 narily used for providing a punched “dot”, A Zontal portion of the frame 20` A tape' drum or spool 22 is removably mounted on the upper end of the standard 2I, preferably being J'Ournaled en a bearing pin 23 secured to the standard 2l. A nut or other removable holding device 24 is pro vided on the outer end of the bearing Din 23 fer holding the tape drum 22 in position on the bearing Din 23 The frame 20 also has Centrally disDOSe‘d near the front thereof an upwardly extending guide Standard 25- The guide Standard 25 is provided With slotted portions 26 and 21, with stop pins 28 and 29 at the upper ends respectively of the slots 25 and 2lThe 10Wer end Of the Standard 2l l’laS a tane guide Din 30 InOunted lìî'leYeOn fOr guiding and directing the tape I0 as it comes from the tape Speel 22, and at the ODPOSíl'Ie end 0f the tape course, at the front of the frame 2li, a tape bear ins strip 3i is mounted. kThe tape bearing strip 3l is held on the frame 20 by e Supporting pin 32. MeChanlSIn iS DYOVlded fOr advancing the tape a predetermined dÍStanCe A Space key member 35 is provided and includes a space key lever 36, 20 25 30 5 40 45 with a ringer portion 3l mounted at one end thereof, This end portion of the lever is recipro- 50 cable _in the guide slot 2l', upward movement of this portion of the lever 3S being limited by the pin 29 and downward movement being limited by vthe' lower end of the guide slot 2l. The other endof the space key lever 36 is pivotally mounted 55 2 2,110,447 the tape ||J forces the tape l0 toward the front on a bolt 38, which extends through the standard 2|. A‘ spring 39 coiled around the bolt 38 with one end bearing on the frame 2D and the other end hooked under the space key lever 36 nor mally urges the spacing lever 36 to its upper posi~ Upon completion of this advance of the tape Ill, tion, in contact with the stop pin 29. A tape actuator shaft 40 is mounted in upward ly extending portions 4| and 42 of the frame 20. the` spring 39 returns the spacing lever 36 to its initial position in contact with the stop member 29. Each repetition of this operation advances A tape driving roll 43, having a covering of suit the tape I0 through one space unit. When it is desired to punch a slot of unit 10 10 able material such as soft rubber is mounted on ofthe device. In this manner, upon a single downward movement of the finger member 31, the tapeY I0 is advanced through one space unit. ’the actuator _shaft 40 directly above >the tape length, the finger member 52 of the punch lever bearing strip 3| in such a manner that the driv ing roll 43 will draw the tape l0 along the bear 5| is pressed'downwardly and the pressure ex-`_ » bolt 51 on the frame 2|) and beneath the spring of advance. 53.

A machine for perforating tape including a 40 tape supply device, means for advancing the tape spring 53 and has a slot 58 formed therein. A die member 60` in the form of a iiat plate of spring steel metal is mounted on the frame2ll thereof, means _for punching in the tape a per erted on the lever 5| is transmitted through the ing strip 3| by frictional engagement of the roll _ end portion of the punch member 63 against the force of the spring 53 and the punch member 63 43 with the tape |0. _ A toothed wheel 44 is also secured to the shaft is forced downwardly through the aperture 62 of v4|) for engagement by a pawl 45. The pawl 45§is the die 60. This removes a portion of the tape I0 in accordance with the form and shape of the pivotally mounted on the spacing lever 36 by a rivet 46, and is held in engagement with the punch and die members'63 and 60. The space toothed periphery of the wheel 44 by a spring 41. key >lever 36 is again operated and advances the tape I0 a single space unit‘for each actuation A punch key member 50 is provided and in cludes a punch key lever 5|, with a finger portion thereof. The tape is thus brought to a position 52 mounted at one end thereof. This' end por-1 for further punching or for the provision of a >tion of the punch key lever 5| is reciprocable in suitable number of spacing units. The operation of the space key lever 36 advances the tape I0 a 25 the guide slot 26, upward movement of this por tion of the lever being limited by the pin 28 and distance which is slightly less than the dimen downward movement being limited by the lower sion from the front to the back of the portion 64 end of the guide-slot 26. The other end of the of the punch member 63 so that upon successive punch key` lever 5| is pivotally mounted on the punchings a slight overlap of the punchings is effected. _This insures a` complete removal of 30 bolt 38 in the standard 2|. A punch spring 53 is provided and is mounted material from the tape in accordance with the at one end upon a lug 54 formed on the frame 20, length of slot desired.
