l .l|PR0VlMF.NTy IN MACHINS FOR ROLLlNG `DOUGH AND CUTTING CRACKERS AND` BISCUIT.

Slpecilicatiuu wrnnng part of Letters PatcntNo. lil, datedMnreh 2, 1836; Reissue No. l lll, dated t -1' .y f May9,1848.

To all whom it may concern:

.Be it known that I, WILLIAM R. Nnvms, of the city, county, and State of New York, have invented certain new and useful Improvements in the Machine for Rolling Dough and Gutting the saine into Crackers or Biscuits; and I do hereby declare that the following is a full, clear-,and exact description of the principle or character which distinguishes them from all other things before known, and of the manner of making, constructing, an'dnsing the cutters which have an up-and-down motion,

in combination with an endless apron which carriesfthe dough to the cutters on which the crackers or biscuits are cnt, and which removes them from under the cutters after being cut, when 'this' combination is produced and effected by conneetin the reciprocating motion of the cutterswith-t ,e said apron by mechanical means to give to it an intermittent motion that will keep the apron at rest while the cutters are cutting into and rising from the dough and then move it lforward the required dis-4 tance to present the sheet of dough for the cntting'of another set of crackers or biscuits.

A A is the frame of the.1nachine,wbieh may be made of either wood or iron.

B isl a. shaft to which'the driving-power may be applied. This is represented as having a winch, C, on one of its ends, which may be used when it is to be driven by hand; but it may be actuated by any other motivepower.'v

D is a fly-wheel onthe opposite end of said shaft.

The shaft B is represented as a crankshaft carrying the cutters and dockers to -be presently described.

On the shaft B there is a pinion, E, from which motion is communicated to the other partaof therapparatus. The pinion E gears into a spur-wheel, F, which revolves on an' 1independeut center or axis, 1.','said wheel 1f oeing intermediate between the' pinion Eand the spur-wheel'G, which is on the shaft of the lower roller, H, of the pair of rollersby which the dough is rolled ont, the roller I being the upper roller of this pair. These are geared toy get-her by pinionson one of their ends, (seen in part at a, and bI i g. l.)v These pinions mesh suiiciently deep into one another to allowpof the adjusting of the rollers to the varying thickness which itl'may be desired to give to the dough, which is done by means of the adjusting-screws l l.' They may be about ve or long, more or less.

is to be placed on' an inclined lfeeding-board, J ,'do'wn'whichv` it will tend todescend by its own gravity, andthe lower portion of it being attcned and passed by hand between the rollers H I, it willbe rolled out bythe revolving vof said rollers yto a `unform*thickness, and will passfrom .them onto an endless apron, K, that passes round the feeding-rollers LM, These feeding-rollers are to remain at rest during the operation of the cutters, and for this purpose have'an intermitting motion given 'to them by means of an apparatus shown on the side elevatioml'gFig. 1, where c is a ratchet' wheel and .d is a small pulley ordruni on the end of the feeding-roller L.

cisv a crank-pin on the ries a md, f, to which is attached a cord or band, i, that passes around the pulley d, and like the y'cord iis attachedthereto, the weight h being suspendedifrom its outereud. By means of thisl apparatnsand of the pawl j, jointed to the wheel d, which engages with the ratchetwheelc in one direction, but does not act up on it in the reverse direction (a device well understood by. machinists) an intermitting motion will be communicated to the feedingroller L and consequently to the endless apron The amount of the Amotion given to the feed- Y ing-apron is such yas to feed the rolled dough tosuch an extent equal to the width of the biscuits or crackersto be cut, and the rollers H I must be so geared as to supply this quantity. 'This may be regulated by changing the pinion E', the center or .axis k of the intermediate wheel, 1E, beiggfmade movablepin a. slot six inches in diameter and about sixteen inches The dough having been properly prepared,v

ny-,wheei D, than mi ed in such manner aste allow the'cuttms and low the upper section bf the endless` apron,

there is an iron plate, (shown at r r in' Fig. 3,)

i convenient mode of moving the cutters up and ion, in the manner of the well-known man-v to admit of such change.y As the dough passes from between the rollers HI it has to descend to the apron K, a distance equal to the diameter of the lowerI roller, as seen distinctly in Fig. 3, and this allows sulicient play to the endless apron for its intermitting motion.

The cutting of the douglll is effected in the followingmannem The sli ft B, I have said, operates as a crank sha Its wrists are shown at m m, Fig. 2. n n are the lifters that embrace the crank-shaft, and are attached to the cutting-slide N, that has grooves in its endsthat are adapted to the guide-tongues o o. The cutters 4and dockersare attached to the bottom of the slide N, as shown atp and in a face view in Fig. 4. The cutters are here represented as adapted ,to square crackers or biscuits; but they may he equally well adapted to the cutting of thbmroirhdf'or in any other form. The plate q is the clearer, and -is shown separately in I ig. 5. Itlis perforat- `dockers to pass4 through itand operate on the dough. Directly under theveutters,yand bewhich plate sustains the action of thel cutters. There should also be a supporting board or table, s, under the apron, to preyent'its swagging withthe weight of the dough. The distanc between the rollers Hf I and the cutters may e about ive feet, as this leaves sufficient room for the proper action, of` rthe respective parts. g 4

I have represented whatI `deem the. most down by using the shaft B as a crank-shaft; but this may beiieected byu rack'and pinle-wheel motion, vorcby a segment-wheel'mo-Lv ion, or by arms or Atappets, and I do not, therelfore, intend to limit myself totlieparticular device herein shown, but to adopt vany equivalent means of attainingthe same zIt will be obvious from ,thepforegoing that 4the,arrungexnex'it,of parts foreonimuniceting "Ph" moti Methos' :aniram-the i-Yrtb i? jiwtons to L ttain-the lia may be substituted.

I have found it advantageous te prepare the dough for being iinallyrolled out by theV rollers H I by passing it through preparing-rollers, which I have .used separate from my machine when the latter" is made to operate by hand.V When it is moved by other power such preparing-rollers may be attached to the machine and be adtuatedv by the same power, and I have soreprescnted it inthe accompaing drawings, but without intending to make any claim to the so attaching it.

O and P 'are vthe auxiliary or preparing rollers, which maybe driven. by an intermediate pinion, Q, gearing into a wheel, R, en the lowerinost of these rollers, S, being an'inclined board upon which to place'the dough.

` `What I'claim as my invention, and desire to ,secure by Letters Patent, is'- l i 1. Cutting bymeans of reciprocating cutters on .an apron uhaving an intermit'te t motion, substantially as described, by com iuing 'and connecting together, in the marjiierubstantially asheren described, tlemiprocatin g motion of the cutters with the intermitl ting progressive `niotion of the apron that carries thedough to and under the cutters, to be delivered, ytis-described, whereby the ,apron 'moves the dough forward the required dis-` tancewhile the'cutte'rs areup, and remains at rest whil dough. Y

2. The stationary plate or Iclearer withJper fox-ations through which the cuttcrsand dockers pass when this is combined with the' reciprocating cutters and dockers, ,A and the a ron that vpasses below it with an intermit t motion, as described. v y WlLLIAM It. NEYINSL Witnesses: I n
