IIVIPROVEMl-NTv IN APPARATUSFOR PERFOR'ATlNG PAPER FOR TEL'EGRAPHING.l

Specification forming part of Leti ers Patent No. 6,33l dated November 2, 11569,v

To all whom it may concern:

Be it known that I, GEORGE LITTLE, of

RutherfordlPark, in the county of Bergen and State of New Jersey, have invented and made a new and useful Improvement in Telegraphic Apparatus; and I do hereby declare the fol-4 lowing to be a full, clear, and exact descrip- Y tion ot' the said invention, reference heilig had to the annexed drawing, making part of this specification, wherein- Figure l is a plan, showing the magnets and paper previous to and to be employed inv transmitting said communication. I make .use of an insulated circuitcloser, over which '-a spring is caused to move by the action of a key, that also turns the cylinder to give motion to the paper. The insulated circuit-closer is so formed, with metal bars and intervening non-conducting material, that the proper pnlsations of electricity are given.

The electricity acts on one magnet to give the power necessary for moving the perforating-punch by means of a lever, and at the saine time a second` magnet clamps the feed to hold. that still while the papelgis being perforated. The movement of the armature and lever for punching the paper simultaneously operates a circuit-changer, that throws the currents from the first and second magnets through a third magnet, that acts to raise the punch, so that it cannot remain through the paper, and this last action again changes the switch so that another pulsation cannot pass through the third magnet until the electricity again passes through the rst magnet. Thus, the rapidity of the perforating operation is only limited by the speed of the electrical current andthe inertia of the parts.

In the drawing, a is the frame ofthe machine carrying the shaft b, on the end of which are the feeding-disks c, that are turned with the said shaft b, by spring friction-plates d. The vertical rods e, passing throughthe frame a, calry the cross-piece el, that presses the paper tothe disks c by the action of the springs 2 2, the force being adjusted bythe nuts 3. `0peningsare formed through the side portions o't' the cross-piece el, and the paper passes through them and between the cross-piece e1 and the lower portion e2, that carries, in the middle, the die e3, for the punch. Above thev cross-piece el are the studs 5 and 6, oneof which recei'vejs the fulcrum-pin 4 of the lever f,fthe other guidesl said lever, and,

by a nut,.limits the movement vof said lever;

and at one end of this lever is thearmature g of the magnet h, and atthe other end the armature 7c of the magnet l",- v and this lever f' ac tuates the punch a, shown by dotted lines in-Fig.'2. The die e3 of the punch is supported by the portion e2. The magnet lt causes the punch a to perforate the paper, and it also moves the lever circuitchanger m, the endI thereof' moving from the non-conducting block 7 to the insulated conducting-block 8. This lmovement directs the electrical current from the frame of the machine through the magnet l, in order that the saidniagnet l may raise the punch instantly out of the paper. The pulsations of electricity are given through the key or mechanism hereafter described, and at the time the magnet h is'changed, and the paper is beingpunched, the feed o't' the paper is momentarily arrested by thepins m1 that are in the poles of the magnet m2, and, g

being magnetized atthe same time as the magnet h, attach themselves to the sides of the disk c, holding them, but the frictional connection d to the shaft b allows that shaft to continue to revolve. The means for giving the electrical pulsations consist of a range of keys, a3 a3, the vsame being extended to any desired length, and operating in connection with the shaft b. The arrangement of letters, figures, or signs, 0n the inger-keys, and the groups of conductors and non-conductors, tov

produce the proper pulsations and intervals vfor theyarious telegraphic characters, being of any-usual or desired character, do not require to be described. l will proceed to describe one ofthe 1in ger-keys, they being alike, except asto the arrangement of the alternate conducting and non-conducting surfaces and spaces. The cylinder o, on the shaft b, is

PATENT OFFICE.,

made of non-conducting material, having l grooves` 9 therein,between the ribs 10. The

circuitcloser p is in the form ot a segmental block occupying the groove 9, and vformed with non-conducting portions 11 between -the Vbars 12, that are united to the metal body of said circuit'closer, and, by the metal. arm 13, connected with the bar g, which forms part ot' the frame of the machine. In shallow grooves `in the cylinder o, at the sides ofthe groove 9,

is a clamping-band, s, that is open on the upper side so as to give access freely to the circuit-closer p. This band s has, near one end, ears, receiving the fulcrum14 ot' thc key a3. the end of which passes into the other end ot' t-he band s, so that the pressure on the finger-key n? first tig itens the band s, clampY ing the cylinder o, and causing it to be rotated bythe depression of the finger-key until arrested by a properly-placed stop, r, taking against the bart, that is insulated from the rest of the frame ofthe machinebut put into connection with the band s4 by .the tlexible metallic strap u. The band s carries a springI l finger, c, that runs over the circuit-closer as.

the key n3 and` band s are moved, and causes the circuit to be opened and closed.A And I remark that tlze shaft b, being turned with the cylinder 0, and feeding the paper between the respective pulsations the distance between the end of the finger 'u' and the tirst bar 12, determines the space that the paper is n10-ved before being perforated. When the fingerkey is released the contractile rubbcr-spring w draws the band s back to its normal position. The stop 18 arrests the further movement. The band s expands su'iciently to lift the end of the finger v clear `of the circuit-closer, upon the return movement. The wire 30 leads from onepole of the battery to the `binding-screw 31. -The other screw. 32, is

connect-ed with the opposite pole of the battery. From 32 is a Wire connecting with the magnet h, and a branch to the magnet l. From 3l a wire connects with the bar q and frame of the machine, so that pulsations ot' electricity can pass from any part of the frame a or q. When a finger-key is operated, such pulsations pass along the arm 13, circuitcloser p, and spring fu, to the band s1 (insulated by the cylinder 0,) by the stop 1", to the insulated bar gt, thence through the magnets m2; y and h to the binding-screw 32. C The pulsation` ot' electricity only passing when one ot' the bars, 12, isin contactwith the spring c, this" circuit is therefore instantly broken bythe movement; but the movement of the armature gand lever f has caused the punch to pertbrate' the paper, and alsol thrown the V leverm up, with its end in contactwith the insulated connection 8, to the magnet l, so that the electricity, passing from the frame a, through m, 8, and l, back to the screw 32,

causes the magnet l to draw down the armature 7c, lifting the punch andrestoring the parts to their normal positions, andy breaking the circuit through Z, by bringing the. lever m` into the position shown in Fig. 2. The direction of the current may be changed by reversi ing the battery-wires, the operation being the same. y The punch might be withdrawn by a spring or permanent magnet, but I prefer the electro-magnet shown.

.What I claim, and desire to secure by Letters Patent, is j 1. The circuit-closer p in the cylinder o, in combination with the band s,

key n3, and linger fv, substantially as and for` the purposes set forth.

2. The feeding-disks c on the shaft bof the cylinder o, in combination with the frictional `connection d and holding-magnet m2, for

moving the paper by the direct faction `of the cylinder o, and arresting the-'movement of the paper when the punch is acting, substair tially as and for the purposes set forth.`

3. The'magnet L, in combination withV the magnet h, lever f, punch n, and circuitchan ger m, for pertbrating the paper, and then drawing back the punch by magnetism, substantially as set forth. l f 4. The circuit-changer m, in combination with the magnets h and Z and lever f, to di- 'ecththe electric current, substantially `as set ort In witness whereof I have hereunto set my i signature this 7th day of April, 1869.

GEORGE LITTLE.
