TELEGRAPHIC-TAPE PERFORATOR.

Specification of Letters Patent.

Patented Dec.3 ,1912.

Application filed July 30, 1910. Serial No. 574,596.

To all whom it may concern:

Be it known that I, EDWARD E. KLEIN- a citizen of the United States of America, residing in the borough of Brooklyn, county of Kings, and State of New York, have invented a certain new and useful Improved Telegraphic-Tape Perforator, of which the following is a specification.

Thisinvention relates to a machine for perforating tapes to be used in the Delany system operated by the Telepost Company. The representation of a dot on such a tape consists of two perforations in a line perpendicular to the tape; and a dash is re resented by two perforations in a line oblique to the tape. There are two punches arranged in a line perpendicular to the traverse of the tape and when the depressed, two punch-actuating magnets are energized as is also the tape feed magnet, the tape being fed when the feed magnet is deenergized. There are two keys to form a dlash. When the first one is operated, one of t e feed magnet are energized and when the second key is operated the other punch-actuating magnet and the 7 energized. When the space key is operated, the feed magnet only is energized. The two punches, simultaneously operated when a dot key'is depressed, will produce two perforations in a line perpendicular to the tape after which the tape is fed forward. When the first dash key is operated, one peroration is made and then the tape feeds; and when the second dash key is operated, the final perforation constituting the dash is made and the two dash perforations are therefore in a line oblique to the tape. hen a space, as between words greater than the normal feed of the tape is required, the space key may be more than once depressed.

The foregoing is a general description of the machine and its behavior and the invention comprises also certain details of arrangement hereinafter set forth.

In the accompanying drawings: Figure 1 is a plan view: Fig. 2, a section on the line 2, 2, of Fig. 1: Fig. 3, a section on l3l16\l1118 3, 3, of Fig. 1: Fig. 4, a horizontal section: Fig. 5, a detail view partly in section and partly in elevation on an enlarged scale showing the head in mounted and in brackets upon which the armature levers of the punch magnets have dot key is punch-actuating magnets and the tape tape feed magnet arewhich the punches aretheir bearings: Fig. 6, a detail view of the tape feed ratchet wheel: Fig. 7, a detail view of a pulley moving with the ratchet of the tape feed and adapted by means of a belt to actuate the paper drawing reel: Fig. 8, a detail plan view, with the finger piece removed, of the dot key: Fig. 9, a front elevation thereof with the finger piece in position: Fig. 10, a diagrammatic view showing the two punch-actuating magnets, the paper feed magnet and the circuit connections of the keys: and Fig. 11, a detail view showing a section of the perforated tape.

The main frame 1 of the instrument may be composed of a single casting. In a bracket thereon at one side is the tape supply reel 2 and on an adjustable bracket 3 on the opposite side of the frame is the tape drawing or take-up reel 4;. The shaft of the paper drawing reel carries a grooved pulley 5 driven by a belt 6 operated from a pulley hereinafter referred to that moves with the ratchet wheel of the tape feed. Bracket 3 is made adjustable by means of a slot and set screws 7, 7, to adjust the tension of the belt 6. The paper tape 8 to be perforated passes across the frame 1 under punches 9, 10; thence over a friction paper feed reel 11 moving with the paper feed ratchet hereinafter described and having its surface covered with some suitable friction material, such as leather, that will grip upon the tape. Above this wheel 11, and acting to press the tape against it, is a spring-pressed idler wheel 12 whose surface is roughened by engraving, cross hatching, or otherwise. After passing between these two wheels, 11, 12, the tape passes to'the winding up or draw reel 4. The punch head is best seen in Figs. 2 and 5.' A block 13 supported upon the upper face of the frame 1 above an opening therein within which and secured to the block is the die plate 14 having in it the female members 15, 16, of the punches 9, 10. These punches are guided in apertures in the lower part of the block at the bottom of a well or cavity therein and also at the top in apertures in a plate 17 screwed to. the top of the block. Coiled springs are applied around the punches between the bottom of the cavity and collars on the stems of the punches. In the opposite sides of the block are screw adjustable back stops 19, 20 for the respective armature levers 21, 22, of the punch magnets 23, 24, and in the top of the block are screw adjustafi'ord a proper able front stops that limit the punch-actuating movement of the levers. These armature levers are of right angular contour. Their downwardly extending arms carry armature pieces that cooperate with the electromagnets and their horizontal parts project toward each other and over the punches and are each provided with screw ad ustable heads 25, 25, that act upon the punches. The punch operating magnets 23, 24, are secured to brackets on the under face of the frame 1 as is also the tape feed magnet 26 which has an armature lever 27 pivoted in.- termediate its end on a hanger on the under face of the frame.

29 is an adjustable stop for this armature lever applied to its outer end and 30 is its reaction spring which tends to carry into engagement with the ratchet wheel 31 the rocking driving escapement pallet 32 pivoted in the inner end of this armature lever. The ratchet wheel is provided as usual with a spring pressed dog 33 and the operation of the driving pawl is,'of course, well understood. On the shaft 35 of the ratchet wheel, which has its bearings in hangers carried by the frame, is a grooved driving pulley 34 that receives the belt 6 that drives the tape drawing reel 4, and fast on the shaft 35 is the friction drive roller 11. It is preferred that the pulley 34 be loosely mounted on the shaft 35 and connected as indicated more particularly in Figs. 6 and 7 with the ratchet wheel 33 by a spring 36 having a turn or two around the shaft and then having one end secured to the pulley and the other to. the ratchet wheel. The spring is so disposed that it is placed under tension each time the ratchet wheel is advanced one tooth by the ratchet driving lever 27 There is thus provided an' elastic connection that guards against injury to the tape because of sudden draft thereon if the belt 6 be unduly tight. Referring now to the diagram (Fig. 10)

it will be seen that when the key marked dot is depressed a circuit that includes the source of energy 37 will be closed at one of the two lower contacts of the key through punch actuating magnet 23 and tape feed magnet 26; and also a circuit from the front lower contact of the key through the punch actuating magnet 24, tape feed magnet 26 and source of energy 37. Both punches 9, 10, will therefore be simultaneously actuated to produce two perforations in a line perpendicular to the tape, When the key rises, the tape is fed by reaction of the armature leverof feed magnet 26. When dash key 1 is depressed, a circuit is completed through punch magnet 24, magnet 26 and source of energy 37 and one only of the punches is then actuated to produce the initial perforation b (Fig. 11)

of the pair forming a dash, and when key dash 2 is depressed, the other punch mag- .and front elevation in as at a in Fig. 1.1.

net 23 is energized as well as the paper feed magnet 26 and the corresponding punch actuated to produce the final perforation 0 constitutingthe ending of the dash reprsented by the two perforations b, 0. When the space bar or key is depressed, a circuit that includes the magnet 26 and source .of energy is completed and on the opening of the key, the paper tape is fed, the punches during this operation being inoperative. The contact plates for the bottom key contacts, as well as the key levers and their top stops, are indicated in the drawings and the wiring is, of course, properly made. It seems unnecessary to describe these well known or obvious things as the diagram view 10) is entirely suflioient.

The dot key is shown in detail in plan Figs. 8 and 9. The details are unessential and the construction and behavior of the'parts obvious and special description appears unnecessary.

I claim:
