JOHN GELL, OF LONDON, ENGLAND.
PERFORATOR FOR USE WITH AUTOMATIC TELEGRAPH-TRANSMITTERS.
SPECIFICATION forming part of Letters Patent No. 751,161, dated February 2, 1904. Application filed November 3, 1902. Serial No. 129,879. (No model.)
To all whom it may concern:
Be it known that 1, JOHN GELL, electrical engineer, residing at No. 48 Highbury Hill, London, N. in the county of Middlesex, England, have invented certain Improvements in Perforators More Particularly for Use with Automatic Telegraph-Transmitters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention consists in apparatus whereby symbols or the like are perforated in a length of paper or other tape upon the depression of a key. It is, however, more particularly applicable for the purpose of perforating the paper or like tape used for VVheatstone or other automatic telegraph-transmitters. I attain this end by means of the mechanism illustrated in the accompanying drawings, in which 7 Figure 1 is a plan. Fig. 2 is a part sectional side elevation of Fig. 1. Fig. 2 is a checking device for limiting upward travel of 2 5 parallel bars. Fig. 3 shows detail of wormdrive. Fig. 4 shows detail of epicyclic box. Fig. 5 is a sectional side elevation of Fig. 4:. Fig. 6 shows detail of parallel bar. Fig. 7 shows numerically the whole of the integers from which the telegraphic symbols are selected. Fig. 8 shows detail of primary and secondary counter-shafts and attendant gear, the platform removed. Fig. 9 gives detail of roller and cam. Fig. 10 gives detail of punch. 3 5 Fig. 11 is a section of punch above the punches or perforating needles. Fig. 12 is a plan looking up of Fig. 10. Fig. 13 is across-section Fig. 1, giving detail of differential feed. Fig. 14 shows detail of lcver-escapement. Fig. 15 shows detail of adjustable bush and holding-screw. Fig. 16shows detail of transverse levers for feeding mechanism.
In the following specification 1 have described my invention as perforating the paper strip usually employed in transmitters for submarine telegraphy. A slight modification adapts the same apparatus for use with land-1 line transmitters. v.
In the drawings, 80 represents the keys, pref 5 erably similar in pattern to those employed in standard type-writers. Each of these consists of a shank b, covered by an indexed button on head 0, said shank taking a guide through a brass plate (Z, screwed to the base-board d of the machine at its lower part and through the 5 5 cover-plate e at its upper end. At the point shown in Fig. 2 the shank Z) has a slot f cut in it, and into this slot is placed the front steel tail of the key-lever g. A compressible spring 71. surrounds the key-shank 1) between the baseplate (Z and the steel tail of key-lever g. 1 The key-levers are pivoted at a given point in their length by resting upon fulcrum-bars 3', (see Fig. 2,) each row of keys being so pivoted that the terminal lift is the same on each keylever. The key-levers are, preferably made of wood, having steel tails riveted at their front and back ends, the back tails of said key-levers being passed into a slot k, formed in the length of the vertical rods Z, which also are guided by passing through base-plate d and upper guide-plate m and have riveted and soldered at their upper extremity plates 72, these plates having small rollers 0 or projections arranged and spaced along their 7 5 length according to the numberof elements composing the telegraphic symbol and the character of the key to Which-each is respectively connected. The roller-plates. a are formed by bending a thin piece of metal over a former, a piece of wire 9 being inserted at the bend. This is subsequently withdrawn and notches cut out according to the rollers same is intended to carry. The rollers 0 are then inserted and the pin replaced. (See Fig. 6.) 5 The upper guide-plate m is secured to side bearers 7, having a notched extension 8, which carry a plurality of pivoted links t, to the other end of which are pivoted the endsof the parallel bars a, normally resting upon the 9 rollers 0. These parallel bars a are so mounted that any vertical movement of the roller-plate 12 gives a vertical motion to the parallel bars. Said parallel bars 14, although grouped together, may be divided into two classes, each 915 class having its particular function, the one translating the characters on the keys into code, the other determining the amount of feed required by the tape for its correspond- ;ing telegraphic symbol and for spacing. For I fashion of metal plates 20', the ends of the responding necessary spacing or feed holes. (See Figs. 7 and 10.) The punches or perforating-needles 21 are formed with a bottom shank 22, the end of which, 22, is cut obliquely chisel fashion for more easily penetrating the 7 paper, and a top shank 22. The markingpunches have an intermediate swell 23, in which is pierced an eye 24, so arranged that same shall come when the punch is'at rest opposite the corresponding slot in the U-slider l6. 7 The upper shanks 22 pass through a top guideplate of steel 25, screwed into punch-shell 14, a compression-spring 26 being placed between the top guide-plate 25 and swell 23, surrounding the shanks 22*. At the base they pass 80 the guide-plate 30, attached to the shell 14. he spacing or feed hole punches 21 are also formed with a lower and upper shank 22 22, respectively, but have shoulders 27 so placed in their length that same come beneath the 5 swells 23 of the marking-hole punches. Hence the marking-hole punches from either side on depression will carry down their respective feed-hole punches. The leading spacing-hole punch 28 is either fixed in the slider by screw- 9 ing or brazing orplaced beneath a cross-bar 29, as shown in igs. and 11. All these punches are guided near the point of penetration by passing through the shell 14. Underneath the bottom guide-plate 30 and sepa- 95 rated from the same by distancing-pieces 31 is the cutting-die plate 32, the holes of which are in register with the guide-plate 30, immediately above and slightly chamfered out- Wardly for clearance of chips. I 0
I have now described the key-actiontrans lating bars and punch and will pass on to the driving, perforating, and feeding mechanism. Dm'm'ng.The epicyclic combination shown in Figs. 3, 4, and 5 is driven by means of a 1 5 worm 35, gearing with a worm-wheel 36, formed or mounted on the periphery of the circular box 3 The worm may be coupled to any convenient source of power, preferably to an electromotor. Attached to the inside 11 of the circular box 37 is the mainspring 38, the other end of which is attached by a screw 39 to a peripheral flange 40 of a disk 41. The disk is pierced at 42 in three equidistant places, bevel-pinions 43 being placed therein I running on shafts 44, cross-pinned, as at 45. The disk has a central boss 46, into which are journaled on either side the respective ends of two different shafts 47 a 47 carrying bevelwheels 48, meshing with bevel-pinions 43, the I bosses 48 of bevel-wheels 48 hearing against the sides 49, which form the sides of the circular box 37, the whole forming an epicyclic combination, enabling the power of the spring to be divided according to the amount required I 5 to the independent shafts 47 a 47. These shafts 47 47 are supported in bearings 50, (see Fig. 1,) secured by screws to the under side of the platform 11. The shaft 47 carries a spurwheel 51, (see Fig. 3,) gearing 3 submarine-cable code these bars are thirteen in numbereight being employed for perforating, one for the escapement release of the punching and feeding mechanism, and four 5 for the differential feed. The parallel bars a are guided by means of a comb o, bridged across them and attached to the plates w w of the punch-link-pivot cradle. Contiguous to this comb a; and hung from a plate so, sup- Io ported in the same manner, is the check-piece 3/ for limiting the excessive upward travel of the parallel bars a. Through the plate w are screwed adj usting-bushes 2, through which are passed screws 1, threaded into the check- 15 piece 3 the advantage of this being that while the check-piece is rigidly held by the screws 1 its relative height with regard to the parallel bars a can be set to a nicety by means of the adjustable bushes 2. (See Figs. 2
20 and 15.
In a line with the punch 2 and bridging the parallel bars is the cradle containing the pivots for the punch-levers. It is built up box 2 5 pivots passing through plates 20 at either side and kept in their place by a cover-plate w. The cradle is secured to a stiff plate 20 in front, which is fastened to a metallic U-piece 3, attached to the upper guide-plate m, said U- 3 piece being slotted for the purpose of forming a comb for the roller-plates a. (See Fig. 2.) Hinged to parallel bars a a a a a "a a u are links 4, to which are loosely pivoted the one limb of bell-cranks 5, tilting on pins or pivots 6, (see Fig. 2,) the other limbs of bell-cranks 5, in connection with parallel bars a a a a", being linked to interlocking pins 7. Bell-cranks in connection with parallel bars u a a a are hinged to bent connecting- 4 rods 8, passing over the top of the punch through pin-comb 8 and attached by pins at their other extremities to upright levers 9, pivoted at their base to cook 10 on punch 2, screwed to platform 11. These upright levers have pivoted intermediate of their length at the point shown interlocking pins 7, entering the punch on the opposite side to the pins first mentioned, but at the same level. Light springs 12 are placed over the crank-levers to 5 overcome any friction and to assist in the dis:
engagement of the interlocking pins when the finger is removed from the key. The punch 2 (see Figs. 10, 11, 12) consists of a shell 14, screwed at 15 to the metallic platform 11'.
55 WVithin this shell 14 is a U-shaped slider 16, guide-plates 17, attached to the side of the shell. keeping same in position. This slider has projecting pins 18, to which are attached the reciprocating pitmen 19. In the upper part of the slider are four slots 20, cut on either side, and into which the interlocking pins 7 at normal position just pass. Through the base of the U-piece pass the punches or perforatingneedles 21. These consist of two kinds, those 5 for the marking-holes and those for the corinto spur-pinion 52 on a small counter-shaft 54, which in turn drives spur-wheel 53 on the same shaft, which latter is mounted in cocks placed at either end screwed to the under side of platform 11. The spur-wheel 53 engages with a spur-pinion 56, fast on the primary counter-shaft 57, said primary counter-shaft being mounted in bearings 58, also bolted (see Fig. 8) to the under side of platform 11, and carrying on its length an eccentric 59, stagger pin escapement barrel 60, having stagger- pins 60 and 60", and at its extremity the cam 61. The shaft 47 carries a large spur-wheel 62, (see Fig. 1,) engaging with spur-pinion 63, mounted on secondary counter-shaft 64, supported in bearings 65. (See Fig. 2.) This shaft carries the sprocketed star feed-wheel 66, mounted in a center line with and a little in advance of the punch-die plate 32, and a ratchet spacingwheel 67. Over said star feed-wheel 66 is a top roller 66, (see Fig. 1,) grooved centrally, as at 66", to accommodate the star-pins and mounted in a hinged flap 66 pinned to punch-frame 1a, a spring 66 being provided to keep roller down and also to aid in raising same when lifted beyond a certain distance.
lmfm-atng.Attached to the underneath of platform 11, (see Fig. 8, the platform in this view is removed by means of supportingscrews 1,) passing through adjustable bushes z, is a block 68, and into this block is pivoted the rocking frame 69. Rigidly attached to the opposite extremity of this rocking frame is a fork 70, engaging with the eccentric 59. The rocking frame is composed of two members conveniently spaced to receive the reciprocating pitmen 19, attached to the slider 16 of punch 2. When the eccentric rotates on the release of the escapement, the rocking frame is first depressed and then carried up to its normal position, thus actuating the slider 16 through the pitmen 19, and thereby perforating the paper. The height of the punches is determined by the adjustable bushes 2 and supporting-screw 1, which also permits of compensation for wear and tear. (See Fig. 15.)
Feacl.Over the parallel bars a are placed five transverse levers 71, (see Figs. 1 and 16,) four of which by means of aforked tooth 71 rest on the feed parallel bars u 10 10 respectively. The fifth representing the fifthhole feed, the limit in this particular code rests upon parallel bars a and a. The five transverse levers 71 are hinged at the back to a cock 72, screwed to the platform 11. Each of these transverse bars engages with a separate tilting bar 73. This engages with the under side of the lip 7 of a hinged tilting hook 7 1, (see Fig. 13,) the series of hooks 7 4 having light expanding springs 7 5, pressing upon the tops of the lips 7 4t, the other end of the spring being secured to a distancepiece 76 between the two cheeks 77, carrying stagger-pins the spacing mechanism. The hooks 7 4 support toothed spacing or feed bars 78. These feed-bars are pivoted at their rear extremity to swing-links 79, hinged on a pin 80,mounted in the side cheeks 77 screwed to the platform 11. The other ends are formed with teeth 7 8, which normally rest in echelon over successive teeth on the feed-ratchet spacingwheel 67 immediately beneath. The rear ends of the feed-bars are retained against a check-plate 81 in one piece with the side cheeks 7 7 in which the swing-links are pivoted by means of contractile springs 7 8 On depressing any key the lever representing the amount of feed required for that special letter raises its respective tilting bar 73, which withdraws the tilting hook 7 4 from its tooth engagement with the feed-bar and thus allows it to fall, the terminal tooth of the feed-bar engaging with the tooth of the ratchet spacingwheel 67, over which it hung suspended. The ratchet spacing-wheel 67, on the secondary counter-shaft 64., is prevented from revolving by means of a pivoted pawl 82, hung on a pin 83, mounted in cocks 84:, screwed to platform 11 and having right-angled extensions or limbs 85 on either side of the ratchet spacing-wheel 67. A bar 86 is fixed between the two ends of these limbs immediately beneath the feedlevers, (see Fig. 8 and Fig. 13,) which are notched to prevent same touching the bar when they are at rest upon their respective hooks. From the ends of thebar 86 depend pitmen or connecting rods 86, pivoted 'to. the feed rocking frame 88, which is hinged to a block 89, secured to platform 11, by screw 1, passing through adjustable bush 2, and two steady pins 90, (see Fig. 1,) said frame being provided with a distance-piece 91, upon which is mounted with an adjustable screw 92 a threaded spring-hook 93, carrying one end of a contractile spring 94. The otherend of this spring is attached to the base of the platform 11. Secured with screws between the members of the rocking frame 88 is acock 95, carrying upon a pin 96 a roller 97, which travels in the roller-path 98 of the cam 61. One of the parallel bars a is lifted upon the depression of every key and the space-bar. V This parallel bar has an additional guide-comb 99, screwed to the platform 11, (see Figs. 1 and 13,) and close to this comb over the parallel bar 14 is the adjustable set-screw 100 of the escapement release-crank 101. This is hinged V to a cock 102, screwed to the platform 11. Pivoted at the end remote, from the primary counter-shaft to the under side of the platform 11 is the escapementlever 103. (See Fig. 14.)
The other end normally rests upon one of the The second stagger-pin 60 1s placed a certain d1stance in advance and at one side, as shown in Fig. 1a. Owing to the tail of release-crank 101 engaging with the hole 103 of extension 103", the escapementlever on depression of the key is removed from stagger-pin 60, and the toothed end passes behind 60 This permits the shaft to revolve until stagger pin 60 strikes the toohed end of lever and is there momentarily arrested. On releasing the key the escapement-lever returns to its normal position, owing to effort of contractile spring 104 permitting the shaft to further revolve until arrested by the stagger-pin 60 coming in contact with the escapement-lever 103. Excessive movement is prevented by the employment of limiting-pins 103.
The primary counter-shaft 57 in revolving carries around with it the eccentric 59 and the feed-cam 61. In revolving this cam 61 clepresses the rocking frame 88, lifting the pawl 82 out of engagement with ratchet-wheel 67. This permits the ratchet-wheel 67 to revolve and advance the tape by means of the sprocket star-wheel 66 on the same shaft therewith. The fallen feed-bar is carried forward with ratchettoothed wheel 67 until it comes in contact with the steel-faced check-plate 104, mounted on end cheeks 105 and thus arrests the motion of the ratchet-wheel. On the further revolution of the cam the pawl 82 rengages with the ratchet-wheel 67 and the feed-bar lifted clear by means of the transverse bar 86 between the limbs of the pawl coming in contact with the heel of the feed-bar 7 8. Said bar is pulled back to its normal position on the tilting hook 74 by the contraction of the spring 78 The check-plate 104: is normally kept hard against screw-shanks 10 1*, which pass through elongated slots 105 (see Fig. 1) at either end, due to the upward pressure of spring h under limiting-key 106, Fig. 1. Beneath this check-plate and pivoted against the end cheek 104 is the thrust-rod 106, toggle-jointed to a vertical rod 1 and to a rod 107, pinned in lugs on the check-plate, rod 1 being hinged to limiting-key lever 109, pivoted to a cock 108, mounted on the base-plate d. On depressing the limiting-key the vertical rod is raised, and by means of the toggle-joint the check-plate is advanced, traveling forward the distance equal to one space, and by so doing the spacing-bars are arrested one tooth earlier than otherwise would be the case. This eliminates the feed-spacing hole between twoletters on the tape, enabling the operator to punch two or more signs in undivided sequence, thereby providing for figures, punctuation-marks, or arbitrary signs.
The operation of my invention is as follows: On depressing a character-key a the end of the key-lever g is lifted, raising the vertical rods Z, carrying the roller-plates 72, thereby raising its respective parallel bars a, inserting, by means of bell-cranks and connecting-rods, the corresponding interlocking pins 7 into the eyes 2 1 of the punches or perforating-needles 21. Parallel bar 26' is also raised, lifting escapement release-crank 101,
drawing escapement-lever 103 off No. 1 stagger-pin This permits the primary counter-shaft 57 to rotate, carrying round the eccentric 59 and cam 61. The eccentric 59 moving in the fork actuates the rockingframe 69, thereby pulling down by means of the pitmen 19 the punch-slider 16, the punches selected by the interlocking pins being drawn down as Well, perforating the paper tape. One of the feed parallel bars is also raised, lifting the transverse lever 71, thereby upsetting tilting bar 73, causing the tilting hook 74 to drop its spacing-bar 78 onto the feed ratchet-wheel 67 below. The cam 61 now comes into action, releasing the secondary counter-shaft, as before described, giving the tape its required feed. Withdrawing the finger from the key causes the escapement-lever 103 to return to stagger-pin 60, completely lifting the punch-slider and withdrawing the interlocking pins from the punch-eyes, also again locking the pawl on the feed ratchetwheel and leaving the machine ready for the next key to be struck. To provide a space, the spacing-bar key is depressed. This in same manner raises the parallel bars a and a by means of lever 111, pivoted to cook 112, said lever lifting vertical rod and platecarrying rollers 0, spaced under parallel bars a and a. As a modification I may provide separate springs for each counter-shaft coiled by means of the epicyclic driving-gear, but prevented from backward rotation by means of a suitable pivoted pawl.
It will be understood that while I have shown the interlocking pins as normally out of connection with the punches and arranged to be thrust into connection therewith to select the same I do not wish to limit myself to this arrangement, though I prefer it, it being possible to reverse the arrangement by having the interlocking pins normally engage the punches'and withdraw those not needed in selecting the punches.
