LANAGAN, of Brooiiiyn, in the county-of Kings, and sta'to of New York, have-invented anew and usei'iil Automatic -T-ablo'-Punch'and'Shears, of which the following is a fn'll, cleapiancl exact description, reference being bad to the accompanying drawing, forming part of this specification, and'in orbich- 1 i g Figure 1 represents-,aplan'of an antomatic table-punch and shears, constructed in accordance with my improvement. a

My invention consists in a. novel combination of devices, for operation in the one machine, specially applicable to punching and shearing or trimming the edges of boiler-plates, and whereby the plate is automatically fediforward, in an intermittent, manner, onor along with a suitablc-bed,.to which it is clamped, and made to pass under an. ordinary or' other suitable punch, and. subsequently, and as the plate moves forward, its edge trimmed by the action of apa'ir of shears working in connection with the punch said combination of devices, including means for varying the-length of theinterniittent;feedof the work, causing, it to travel in opposite directions, as desired, or arresting itsti'avelwithont stopping thepunch'or shears, and for feeding it in either direction by a motion derived from thatiof the shears,'an'd irrespective of-the general feed of it, in connection with the punch.

Referring toj th'e accompanyingtdrawingpA is a-bed, to which the plate or work, represented by red lines. in fig. 1, is or niay be secured by clamps a a,- adjnstable along a grooved, made in the top of the bed near its inner et ge. This-bed is arranged to travel, by a series oi'interm'ittent feeds, lengthwise of itselfl in either direction, in oi ialong rails cc of a table, B, said bed, or work thereon, crossing or worlring'at right angles to a punch .or punching-apparatus, C, WlIlQiIZIlHty be of the ordinary description used for punching. boiler-plates, and which, where driven by power, may be worked-with a belt, by fast and loose pulleys, d d, on a shaft, e, and. pinion I) on said shaft, working into n spur-wheel, E, hung on the operating-shaft of the punch. F is atilywhech o nthe shaft e, connec ted with whiohlmay or may not be a handle for doing light work by hand. 7 G is a spur-wheel, on a secondary shuft,f,-for giving motion to the shears, as hereinafter described.

','lhe feed of the bed A, with the worlc on it, in an intermitteht manner, so as to bring the work under the punch, at regulator fixed dist-ances apart, is or may be effected automatically, ineither or opposite directions, by or;throngh.reversely-arranged pawls lq h, driven by, an oscillating-shaft ll, and biting (when in gear) into jteethz' iiri the bed A, only oneof such pawls being in gear at a time, according to-the direction in which it is rcq nircd to .rnove-the bed, or, when iii is required to arrest tl e'tra'vel of the bed, throwing bothpawls out of gear thcrewit'h, without stopping the motion or the punch or of the shaft v i The means for (loingthis'is or linaybeas follows The shaft H is oscillatod by or through a lever, 1, fast thereto, and rod J, connected byan eccentric 01' crank-pin, K, on the punch-operating shaft, which latter may be provided with a sliding clutch, L, for throwing the punch in or out of-working-action, asdesired.

To vary the length of feed, as established by the pawls g h, accordin'g 'to the distanceapart, it is r'eqnired to punch the holes, or other circumstances.

The red J is connected with th'elevcr I by or through either one of 'a series of link-pinholes, or otherwise, so as to'give more or less throw to the lever, and consequently increased or diminished'feed to the pawl under action. The pawls g h are connected to the shaft H'by' being pivoted to arms/g it, carried by the latteigand are thrown in or out of gear with their. respeetii'c teeth 2' and j by or through levers, g h, in slotted gear with the 'iaawlsby pins .9 & projecting fromthe latter. These levers- 9 h'f are or may be controlled by a cross rockingj beam, g operateilby a hand-lever, g, through pitman g, in such a manner as that, at a certain elevation of the bandi -lever g, the rocking-beam g, on which the free' endspf the levers g it rest, are made to adjust said leye'rs 9 k, sethat both pawls, j and h are out-of gear with their respective teeth, z'j; but on elevating to a given further distance the hand leversgf, the pawl it will be put in gear with its-rack or teeth j,' o r, on depress ing said hand-loser to agiven distance below its first-mentioned position, the pawl y will be thrown intogear' with iis'r-ackor-tceth z', th reversely-aeting pawl]: falling by the dropping of its lever la -out (If gear with the -In thiswoy; may the bed A'bestoppedorstarted,aud; run in either -direction bye simple-adjustment of the hnnd loyer 9 without ehaiigin-g or interfering with" the motion of: he shaft v To keep" the bed A steady in-its forward feed, .which'is when operated by ,theipawlig, a'eheck-muvl ordog',

These shears, of which M is the stationary eutte'r, and N the working one'or jaw, are 'carriedby a sliding block,-O,

adjusteble along a bed, 1?, by a scrcw, Q, operated by a hand-crank or handle, for the purpose ot' regulating the action of the shearsrelatively to the edge of the plate. The working-jaw N is driven by a crank, Z, and pitman I, from or by the shaft f.

In'gear with this double pawlm by a pin, sf, is a slotted lever, m, working on it fulcrum, as at u, and

connected at its-free end-with a' hand'lever, 911,, that, accordingly as it is raised or l'oweredand aiij-usteihlserves tot-brow either endof the double pawl mf' into or out of gear with the teeth o 'r rack j of the bed A, and'so, with-' out stopping or changing the motion of the shaft R, feeding the bed A. in an automatic andregularmannen forwards. or backwards, as desired,lby a motion derived 'directlyfrom the-shears, or arresting the movemento'f the bed without stopping the shears, as the case may be, or exigencies off the work requ ire.

QWhat is here claimed, and desired to be secured by Letters Patent, is-4 1. *In combination with the punch G, the plate-carrying bed A, arranged to slide crosswise of the punch, and 'pro videdsvith racks or teeth z j on opposite edges of it, reversc-pawls g Ii, connected by :irms g h with a.v vibrating-shnft I-I, slotted levers g 71 in connection with said pawls, and beam-lever g for throwing either pawl in gear with the bed, or disconnecting both therefrom, to reverse or stop tbo'motio'n of the bed without changing or arresting the mo,v,ement of the punch, essentially as specified.

2. The combination, with the-pun'eh Q, of-the intermittently-tedbed A end shears M N, nrranged as described, for operation together uutomatieally to puneh tho plate in aregular or uniform manner, and to,
