A. E. LAZELL AND D. LAZELL, OF CHICOPEE FALLS, MASSACHUSETTS.

i BREAD-CUTTER. c

Specification of Letters IPatent No. 8,193, dated July 1, 1851.

To all whom t may concern:

`Be it known that we, ALMoN E. LAZELL and DAvENPoRT LAZELL, both of 0hicopee Falls, in the county of Hampden and State of Massachusetts, have invented a new and useful Improvement in Machinery for 0utting Bread; and we do hereby declare that the following isa full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, which make a part of this specification, in which i Figure l, is a perspective view `of the machine, showing the knives in their position soon after they have commenced cutting; the fingers, or prongs, which hold the bread against the knives as serving for guides, and the bars or ribs which guide and support the knives at all times, and also support the bread before and after it is cut. Fig. 2 is a plan, or side view of one of the knives before itis attached `to the arbor, showing its form.

Our improvement consists in fitting a set of knives, each made in the form of` an ec centric circle, to an arbor and having them work in guides, and with holders, in such a manner that by causingt-hem to revolve, by means of a crank, (or otherwise,) a whole loaf may be cutinto suitable slices, at every revolution, wit-hout breaking or crushing the bread.

We make a suitable frame A, A, Fig. l. On this we place a suitable bed piece, B B The central part of this bed piece we construct of bars or ribs,.as seen at 0, t 0, Fig. l. These bars being of the thickness we design to cut the slices of bread, (say half an inch,) they serve to sustain the loaf while cut-ting, and also to guide the knives.

We make the knives of steel, in the form of eccentric circles, spiral lines, or scrolls,V asseen in Fig. 2, the cutting edge being on the periphery or spiral line. We fit these knives on a shaft, as seen in Fig. l, at the proper distance from 'each other to correspond with `the bars 0, 0, so that the knives may pass between them, and `be guided and steadied by them. We make a set, or-series, of fingers, or prongs, D, Fig. 1, which we attach to the bed piece in such a position that the spaces betweenthein will correspond with the spaces between the bars, C, 0, so that these fingers serve both to hold the loaf against the` cutters while cutting and as outside guides to that part of the knives which is most distant from the shaft and most liable to tremble.

A The number of bars, 0, 0, the ngers D, and the knives, E, should be equal to the numberv of slices into which a loaf is to be cut; and the thickness 1of the bars, and

fingers, and the spaces between the knives should be equal to the desired thickness of the slice.

When the machine is co-mplete, as represented in Fig. l, by means `of the crank, F, (or by any other convenient means we points, (at E,) pass down below thebars 0,0. We then placethe loaf on the bars,` 0, 0, between the knives, E, and the fingers, D, when, by continuing to turn the crank in the direction indicated bythe dart, the

whole loaf will be cut into slices of equal thicknesswithout crushing or breaking the y bread.

The advantages of our improvement over turn the knives forward until the eXtreme edges of the knives cutting so gradually that there will be no danger of breaking the bread, even `though it be stale, or of crush-` ing it, when quitenew. And the guides `being composedof the bars, or ribs, below, `and thengers above, the center, the slices `willbe cut with perfect accuracy,` and at right angles to the lengthof the loaf. And a whole loaf may be cut as quickly as'a single slice by any other contrivance now known.

`That-'we claim as our invention, and desire to secureby Letters Patent, is-

The use of ajseries of knives, or cutters (E) made in the form of eccentric circles,

or scrolls, with the cutting edge on the' periphery, so as to represent a spiral line, or curve, (as seen in the drawings), when combined with the bars, or ribs, (0, 0,) of the bed piece which serves to sustain the loaf, and also to guide the knives and with the fingers, or prongs, (D,) which hold the loaf against the knives while cutting, and also act as outside guides, when the whole is constructed, arranged, combined, and operating, substantially as herein described.
