Abstract: 1875. Brookes, A. G., [Library Bureau]. Jan. 28. Ruling-machines.-Relates to machinery for perforating, ruling, cutting, and delivering in counted batches cards, paper, &c. for indexes, book-keeping, records, &c. A feed-hopper, shown in Figs. 4 and 7, is formed of slats b on cross-plates b<1>, side guides b<2> on cross-bars b<3>, and sleeves b<4>, b<5> mounted on tubes or bars b<6>, the rear guides b<2> and sleevee b<5> being adjustable on the bars b<6> by racks and pinions b<8>, and end guides b<10> on rods b<12> adjustable on sleeves b<13>. The sheets or cards are drawn one by one from the hopper by a suction device c<24> or feeding- mechanism, a ram or reciprocating part of which is located below the hopper and consists of a frame of rods c, c', to which is secured a plate c' provided with a nose or separator c<5> forming the upper part of a mouth into which the card is drawn from the hopper. The lower part of this mouth is formed by a plate c<6> pivoted below the plate c<5> and operated by a crank c' connected by a link c<8> to a lever c<9>, which is pivoted on a bell crank c<12> connected to the ram, and linked to a bell crank mounted on the lever c<12> and operated by a cam. The suction device c<24> is carried by a tube c<22>, which is connected by a tube c<23> and union c<21> to a cylinder c<18> carried by the ram and reciprocated relatively to a fixed piston and rod c<19>. The part c<24> is linked to the ram frame, and provided with lugs c<26> adapted to be engaged by a jaw c<27> of a lever, which is mounted on a shaft c<29> and provided with a lug c<30> for engagement with a lug c<31>on a lever c<32> operated by a cam. The card passes between the parts c', c<6>, and the part c<6> is turned on its pivot to form with the part c<4> a nipping-device. The card then enters between feed-rolls c<35>, c<36> operated by any suitable mechanism, the roll c<35> being here operated by rods pivoted on cranks on a rock shaft c<39>. To ensure the feeding of only one card at a time, a stripper or flexor is provided, and consists of two pivoted retarding-fingers c<52> provided with a shoulder c<55> and a plunger c<56> engaged by a hub c<57> on an arm c<58>, which is mounted loosely on the shaft c<29> and limited by a set-screw c<59>, and held up at times by a pivoted finger c<62> adjusted by a set-screw c<64>. A projection c<66> on the lever c<58> is adapted to strike the upper end of the finger c<62>. A bevelled end c<67> of the lever c<58> is adapted to slide beneath a ledge c<68> on a stem c<69>, which is normally held down by a spring c'‹, and passes through a gland c<71> of the the vacuum eylinder and carries a valve for opening and closing a port c<73> of the suction apparatus. The hub c<57> is mounted eccentrically and retained. by a set-screw for the adjustment required for various kinds of paper. The cards fed as above are received by flared open ends of guides d<1>, and pass between tension rolls or friction feeds d', d<3> shown in detail in Fig. 10, two pairs being placed both in the front and rear of punching-mechanism E, Fig. 4. The card &c. is momentarily stopped for the punching operation by a gate e, which is provided with an adjustable rib e' and pivoted on cranks e<3> of a shaft e<4>, and raised and lowered by a rod e<5> pivoted to a lever e<7> actuated by a cam e<9>. To keep the gate level, it is secured to a bar e<10> pivoted to a link e<12> in turn pivoted to the lever e<7>. The punching-mechanism is mounted in a frame e<15> having slideways for a punch-carrier e<16> with gangs of punches e<17>. Each punch can be withdrawn from operation, being normally held down by a pin against which bears a set-screw e<19>, the parts being preferably carried in a removable holder e<20> retained by a set-screw e<21>. The punch is surrounded by a stripper e<22> . A die or cavity in a box e<25> is placed below the punch, and the chips fall through a hole e<26>. The punch-carrier and punches are operated by rods e<27> operated by cranks e<28> fast on a shaft e<29> and actuated by a cam e<30> and lever e<31>. From the punching-mechanism the cards &c. are fed to ruling-mechanism with a principal ruling-spindle f and a co-operating lower spindle f <1>, each provided with rings f<2>, f<3>, and held towards each other by a spring, and an inking-roller f<5> and pan f From the ruling-mechanism the cards &c. are caught by a combined feeding and cutting mechanism comprising upper and lower rolls g, g', with middle cutting-rings g<2>, g<3>, and feed-rings or tension collars, preferably of rubber, the rings g<2> being fast on the roll g, and the rings g<3> loose on the roll g<1> and held against rotation by a spline g<5> and pushed against the cutter g<2> by a pressure block, which is carried by an arm g' and is preferably made of fibre. The cut cards &c. are received by feed-rolls h, h<1>, the latter of which is preferably covered with rubber. Deflectors h<2>, h', Figs. 4, 21, and 22, and guides h<9>, h<10> are arranged to direct alternate streams of cards downwards and upwards respectively to feed-rolls h<5>, h<6> and h<7>, h<8> delivering to magazines k, k<1>. The deflectors are slid into position on a fixed rod provided with a spline h<13> embraced by arms h<14> of the deflectors, which are retained by spring friction devices h<16>. Automatic counting. mechanism is operated by a trip c<45>, Fig. 7, an arm c<46> of which is normally raised by a card fed between the parts c<4>, c<6>, so that its free end strikes an arm c<48> of a rock-shaft c<49>. The shatt c<49> carries a crank provided with a pawl l<1>, Fig. 15, engaging a ratchet-wheel l<2>, which is formed with teeth corresponding in number to the cards &c. required in a package, and provided with a retarding device or spring l<3>, and a finger l<4> provided with a wedge-shaped portion l<5> engaging once in every cycle with a roll l<6> projecting from a stirrup l<7> on a rod l<8> pivoted loosely on the ratchet shaft and held upwards by a spring l<10>. A latch l<12> is pivoted at the lower end of the rod l<8>, and rests on the end l<14> of a bell-crank lever l<15> linked to the adjacent crank on the rock shaft c<39>, Fig. 4. In the outer position of the rod l<8> the latch is out of engagement with a lever l<18> on a shaft l<19>, which carries a dog l<21> normally held against a stop l<22> by a spring and engaging a trip l<24> pivoted on one member l<26> of a clutch, the two members of which are normally disconnected. The clutch is connected by the engagement of a pawl l<28> operated by a trip l<24>. A cam l<31> on the part t<26> bears on a roll of a pivoted lever l<33>, Fig. 4, connected by a rod l<34> to a bell-crank lever linked to a crank of the magazine, these cranks operating shafts l<38>, l<39> with depending gates l<40>, l<41>. The cards &c. rest against the gates, and, when these are opened, are delivered into chambers l<42>, l<43>. The chamber l<42> is mounted on a pivot l<44>, and normally locked by a latch which engages the upper portion of the chamber l<43> and is lifted, when desired, by a cord l<46>. Automatic stopmotions are provided at various parts of the machinery. A battery &c. m is fitted with connections m<1>, m<2> to make and break contacts m<3>, m<4>, Fig. 21, preferably brought into contact by the rocking of the bar m<5> provided with a finger m which is depressed by the contact m<3> and operated by a detector m<7> hanging over the path of the cards passing to the upper magazine. Contacts m<8>, m<9>, Fig, 25, are fitted against the guide d', Fig. 4. The contact m<9> is operated by an insulated member m<10> projecting from a detector m<12>, the feet m<13> of which depend on the opposite sides of the guide a<1>. Other detectors may be provided where desired. The driving-mechanism is provided with a controlling set of contacts, shown in Fig. 4 with one contact m<17> on a finger m<18> projecting from the shaft c<39>, and the other contact m<19> stationary. Any tripping clutch mechanism is used for stopping the feed when the electric circuit is closed, that shown in Fig. 19 comprising a solenoid m<20> operating a tripping- mechanism for a weighted lever m<21>, engaging a shipper block connected to a friction &c. clutch. The tripping-mechanism comprises an armature. pivoted to slide on a post m<27>, normally retained by a spring, and when attracted brought opposite the end of a swinging lever m<30> engaged by an oval cam m<33>. The lever m<30> releases a latch m<34> from a lug on the lever m<21>, which drops and disconnects the cam shaft a, Fig. 4, and driving-gear.
