GEORGE Jl HILL, OF BUFFALO, NEW YORK, ASSIGNOR TO HIMSELF AND WALTER S. OVENS, OF SAME PLAGE.

CRAGKER-M'ACHINECUTTER.

SPECIFICATION forming part of Letters Patent No. 230,480, dated July 27, 1880. Application filed March 8, 1880. (No model.)

To all whom it may concern Be it known that I, GEORGE J. HILL, a citizen of the United States, residing in the city of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Cracker-Machine Cutters, of which the following is a specification.

One of the objections to machine-made crackers cut in the ordinary way is that the edge on the side or periphery of the cracker is left rough by the cutters.

The object of my invention is to overcome this objection, and also to form the top of the cracker; and it consists, first, in the` arrangement of a cracker-machine cutter so as to be capable of turning back and forth at right angles to the line of its cutting movement, in combination with suitable mechanism for producin g such movement, as will be more clearly hereinafter shown; second, in a novel mechanism for giving an impression or form to the top of the cracker 5 third, my invention further consists of a cracker-machine cutter having its bore slightly enlarged above its cuttingedge, in combination with a follower for giving it sufficient pressure to enlarge its diameter a little after it has passed into the cutter above the cutting-edge, and then forcing it back and out through the opening forming the cutting-edge, whereby its diameter is reduced and its edge thereby made smoother, reference being had to the accompanying drawings, in whichy Figure l is a side elevation, showing the cutter at the limit of its upward movement. Fig. 2 represents a vertical central section through the cutter (theA cutter being shown near the limit of its downward movement) and a longitudinal section through the cross-head in line X X, Fig. 4. Fig. 3 is a top view, showing a horizontal section through the cutter and a portion of the device for turning it on its vertical axis; and Fig. 4 represents an end view of the cross-head' and a -portion of the cutter. v i

A represents a suitable cross-head, to which my improved cutter may be attached. A' A2 are the front and back of the same 5 B, the bottom. It is supported upon 'springs A3, and

kept in the line of its movement by guide-rods B, and is composed of metal or other suitable material.

O is the cutter; D, a tubular piece, upon which it is tted so as to turn easily, which latter is fastened to the lower part of the crosshead B by screws C'. The cutter is prevented from dropping down off from this piece by means of a slot on the inside of it, and a pin,

c', on the cutter, which projects through said slot, as shown in Fig. 2.

It will be noticed that the cutter is of slightly larger diameter on the inside above the cutting-edge. This allows the diameter of the cracker G to expand a little after it has passed above the cutting-edge, as shown.

O2 represents a small bar or arm rigidly fastcned to and projecting out from the cutter C, the outer end of which passes through the bar I', which is secured to the cross-head by holding-pieces l, through the lower ends of which it passes, so as to have a free horizontal movement backward and forward.

l2 is a swinging arm jointed to the crosshead, as shown in Fig. l, to which the bar l is jointed at 13. The lower end of the swinging arm I2 is provided with a pin or roller, J2, which passes into the slot in the inclined bar J.

`It will be seen that amovement of thecrosshead downward will cause the bar I2 to swing in the direction of the arm K, Fig. 1, and thereby move the bar I in the same direction and impart a partial rotary movement to cutter C, which movement is reversed whenthe cross-head rises again.

f represents a follower having a sharp knifeedge, F', projecting outward around the bot-` tom, as shown. (See Fig. 2.) It is held rigidly to the bar E2 by rods or bolts G', and is held downward to the bottom of the cutter, when not cutting through the dough, by means ofthe springs F* on the bolts F,which bolts pass through holes in the bar E2, and are rigidly fastened to B, so that said barE2 can move easily up or down, the springs F4 holding it down to give the pressure to the cracker and cause it to expand slightly in diameter, so that when the cross-head rises and the follower forces the cracker out through the lower end of the cutter its rough edges will be made smooth by being pushed back through the opening forming the cutting-edge. or by the turning of tl1e same(the cutter) while bein g forced out.

A portion ot' the follower f is represented as broken away so as to show the inside clearer, f', the office of which is to force the cracker, by a sudden quick movement, from the followerf after the follower has forced it out of the cutter, which operation is performed during the upward movement of the crosshead. It is connected by a rod, E', to a bar, E, which has a free vertical movement up and down on the bolts L, and is kept up by springs L. The bolts L are rigidly fastened to the bar E2, so as to move with it. M is an angular bar fastened to E.

H represents a vibrating arm arranged to turn on a standard, H', permanently fastened to the base of the machine, so as to be independent of the cross-head. The arm H is provided with a pin or roller, N, which projects into the opening under the angular piece M, so that H is made to vibrate by the movement of the cross-head.

O represents a small vibrating arm jointed to a bar, 0', on the cross-head. This bar O is arranged so that when its outward end is moved up it takes the course taken by the dotted lines P. It is prevented from moving downward too far by af projection on the opposite side, (shown by dotted lines,) which strikes against the bar O or standard when the limit ofits downward movementisreached, and is kept down in position by the spring P.

1t is obvious that a downward movement of the cross-head will cause the end h ofthe arm H to move upward in the line of the dotted lines R, and that the end h2 of the arm O will be raised up thereby and allow it to pass, after which the arm O is brought back to its normal position by the spring P, and that as the cross-head rises the movement of the arm H is reversed, and as the end h moves down it comes in contact with the top of the end h2 of arm O, which in that position is unyielding, so that the end h of arm H is lifted up and the opposite end correspondingly depressed, which operation presses the bar E and the clearer f' downward, so that the clearer projects below the bottom of the cutter, as shown at S in dotted lines, Fig. l, and is then released by the end h moving` far enough in the direction of the dotted lines R to allow it to pass by the end 7b2 of the arm O, when it is quickly brought back to its normal position by the springs L.

The impression is given to the cracker during the downward movement of the crosshead by the swinging bars T, jointed to a bracket on each end of the cross-head, as shown in Fig. 2, so that their outer ends will be lifted up by a projection, T', (shown in Fig.

2,) arranged at some convenient point on the machine and cause their inner ends to press the bar E2 and follower j' downward suiciently to give the required impression, which impression is given when the cross-head has nearly reached the limit of its downward movement.

In operation the action of the machine is as follows: When the cross-head is forced downward the cutter C, which moves with it, is made to rotate slightly, as above described. During this part of the operation the cutter passes through the usual thin sheetof dough, and the cutting-edge, when at the limit of its downward movement, rests against the surface upon which the dough is placed, so that the cracker or disk of dough, which is now within the cutter, has forced the follower f upward, as shown in Fig. 2, and the pressure of said follower, which receives a slight reverse or downward movement near the limit of the downstroke of the cutter, for giving an impression to the cracker by means of the swinging bars T, as specified, causes it (the cracker) to expand a little in diameter, so as to ll the larger bore of the cutter above its cuttingedge. (See Fig. 2.)

During the return -or upward movement of the cross-head and cutter the cutter receives a slight rotary movement the other way, and as it rises allows the follower j'to be moved downward by the force of the springs F4 and thereby push the disk of dough out through the cutting-edge, whereby its diameter is reduced, and the friction or adhesion of the dough to the cutter causes the lower sharp edge of the cracker to be slightly drawn up and rounded. After the cracker is forced below the cuttingedge of the cutter by the follower f the inside clearer, f', while the cutter is moving upward, forces it by a quick sudden movement therefrom, as hereinbefore mentioned.

The lower face ofthe follower f, when at the limit of its downward movement, is down to or below the lower edge of the cutter, and in its upward movement rises high enough to allow the cracker to be forced up within it and its circumference enlarged, as hereinbefore mentioned, so that it is contracted while being forced out, and the usual lower sharp edge of the cracker is consequently rounded up and made smoother, thereby producing a cracker having both the upper and lower edges rounded and greatly improved in appearance.

I claim as my inventionj 1. The cutter G, in combination with the tubular piece D, upon which it turns, and a suitable device, substantially as specified, for operating it, as and for the purposes set forth.

2. A cracker-machine cutter or cup, C, having the inside diameter enlarged above the cutting-edge, in combination with a follower, j', and mechanism, substantially as described, whereby the follower enlarges the diameter of the cut cracker and forces the cracker, after its IDO IZO
