Specification forming part of Letters Patent No. 215,006, dated May 6, 1879; application led January 17, 1879.

To all whom it ma/y concern.-

Be it known lthat we, WILLIAM LAMPERT and HENRY HUBER, of Grestline, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in Machines-for Making Bretzels; and we do hereby declare that the following is a full, clear, 'and exact description of the invention, which will enable others skilled in the artto whichit appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification, and in which- Figure 1 is a plan view of our improved bretzel-machine. Fig. 2'is a longitudinal section of the same,I and Figs. 3 and 4 are side views thereof. Fig. 5 is a section of thefrolls.

The same part in the several figures is denoted by the same letter.

This invention relates to certain improvements 'upon our machine' for making bretzels, patented November 28, 1876, and numbered 184,786, its object being to feed `and reduce the dough to the required thickness, dust or sprinkle the dough, stamp vit into shape, and expel it upon a delivering-apron or i'nto pans placed upon the latter, all in one continuous operation, and simultaneously therewith, to remove and discharge from the stamping-cylinder scraps, and scrape or clean the expellingcylinder.

To these ends our invention consists of the devices composing the same, as hereinafter 'described and claimed.

In the accompanying drawings, A A refer to two side supporting-frames connected together at their lower ends bycross-pieces a a andat their upper ends by the cross-pieces b b'. Bl is a table or board fastened upon the lcross-pieces a of .the frames A, andprovided at its ends with rollers or cylinders c o; whosecylinders hung preferably one above the oth/er, the shaft of one bearing iu movable blocks g, fitting iu slots in cross-pieces h, between the two uprights of each of the side supportingframes A, as clearly seen inthe two side views marked Figs. 3 and 4. Theishaft ofthe other or upper cylinder, O1, is hun g in similar blocks, i, bearing upon springs il, seated in sockets 1', formed in the upper ends of the upright frames A, at the bottoms of slots i3, holding the blocks t'. The blocks t are held in place by plates j, litted in the slots t3, with their ends let into recesses j', and set-screws k passing down through the plates j and bearing against or upon the blocks t'. This manner of adjusting the shaft of the cylinder C in position 'provides a yielding surface of contact between the two cylinders for the passage of the dough. The screws 7c enable the bringing of the cylinders closer together, or the increasing or diminishing of the pressure between them. The upper cylinder, C', is provided with a number of dies or cutters, D D, either in the shape of a bretzel or jumble, or they may be made to conform to any other shape desired. Each of these dies or cutters is removable for convenience in replacing the same by dies or cutters of any other conguration. To this end the ends or heads of the cylinders are constructed of spoked rings E, with annular grooves or chambers El to receive the ends of the dies or cutters D D', and tted upon the shafts of said cylinders by hollow sleeves or hubs E2. Only one of these heads -or ends of each cylinder is removable, however, that being su'iicient for the removal of any one or all of the dies, which removable ends or cured in position upon the cylin rshafts by nuts or burrs E3. Upon each side ofthe dies or cutters is placed athin ring, hich penetrates a greater or less extent a gr ove, F', in each side of the lower cylinder, C. The object of this is to prevent the dough projecting from the sides of the dies or cylinders. In between the heads or rings E and the rigs or'ilanges F are interposed packing-rings l.

G is a cone ortapering device arranged within the cylinder C', with its tapering or smaller end vterminating at the lopen sideof the said cylinder, from which side of said cylinder extends a discharging-spout, G. By

this arrangement it will be seen that the scraps, falling th rough the interstices between the dies or cutters of the cylinder C' as they cut the dough, will come into contact with the inclined surface of the cone, and thus be conducted to the open side of the said cylinder and allowed to fall upon and be carried on' by the spout G.

m m' are cog-wheels engaging with each other, and supplied to the opposite ends of the cylinders C C for causing their simultaneous operation or rotation, the lower one,vm, gearing with a similar wheel, n, on the shaft of the band or driving wheel f.

Arranged within the cylinder C is a number of studs, Il, say, about six, (though only four are shown,) supplied to each bretzel or jumble, they being tted to project through apertures in the cylinder when acted upon as presently described, and provided with heads upon their inner ends to prevent their falling out when projected.

I ,Il refer to two inner cylinders, one arranged within the other and both within the cylinder C. The cylinder I has a series of peripherical apertures, I2, through which the inner ends of the studs H are inserted, with their heads resting against the periphery cf the cylinder I, as clearly seen in Fig. 2. The cylinders I Il are free to revolve with the rotation of the cylinder C.

From this arrangement it will be seen that the studs H, at the bottom of the cylinder C, will be projected so as to expel the bretzel or bretzels by the cylinder l, and that, as the said projected studs are carried up or elevated with the revolving cylinder C, they will be retracted by the cylinder Il, and as the retracted studs again descend they will be again projected by the cylinder I. The expelled bretzel or bretzels will fall upon the delivering-apron, or rather into the pans placed thereon.

J is a scraper fastened in proximity to the cylinder C for cleaning the saine, and K is a plate arranged upon the opposite side of the said cylinder for preventing the bretzel or jumble from accidentally leaving or falling off the cylinder just prew'ous t-o delivery. L is the feeding-trough, secured upon the crosspiece b' of the supporting-frames A, about opposite the point of entrance between the cylinders C C. M M are two rollers arranged at the inner end of the trough L, and one above the other, the purpose of which is to reduce the dough as it leaves the trough to the requiredthickness. Thir shafts are hung one in the side supporting-frames A, and the other in blocks or bearings o o, seated upon springs o o let into sockets at the bottom of slots o2, within which said blocks are placed. Disposed in the same slots are plates o, with their ends let into recesses at the sides of said slots. o4 o are 'set-screws passing th rough the plates o3, and bearing upon the blocks or bearings o o. This mechanism permits of the varying of the space between the rollers M M to regulate the thickness of the sheet of dough. The shaft of one of the rollers M M' is provided with a cog-wheel, p, gearing with the driving cog-wheel n, through which luotion is imparted to the lower rolle, M, whose shaft is further provided with a pinion, q, meshing with asimilar pinion, q', on the shaft of the upper roller, M'. The pinions q q' transmit motion'to the upper roller, M. The teeth of these pinions are somewhat lengthened to permit of .their engagement as the rollers M Ml are adjusted a greater or less distance apart in regulating the thickness of the feeding of the dough.

N is the duster or sprinkler, or a receptacle, with a perforated bottom, hung from a bow or rod, N', fastened tothe frames A in any suitable way. It is hung or suspended directly above the feeding or reducing rollers M M' for the obvious purpose of dusting or sprinkling, either or both, the rollers and the passing dough with our. To impart the desired vibratory motion to the sprinkler it is provided with an arm, r, which is struck by the teeth or cogs of the gear-wheel m of the cylinder C.

A pawl, s, hung to one side of one of the frames A, and engaging with a ratchet, s', on one end of the shaft of the main driving-pulley f, prevents the reverse movement of the machine.

By means of this machine it will be observed that the feeding and reducing or regulating the thickness of the feeding of the dough, the dusting or sprinkling of the dough, the stamping of the same into shape, and expelling it upon either a delivering-apron or into pans placed thereon are all performedin one continuous operation, and the scraps removed and the expelling or lower cylinder cleaned simultaneously therewith.

Various other advantages are secured in the details of the adjustment of the parts.

We are aware that a roller for projecting plungers has been loosely arranged within a stamping-cylinder, and that a revolving disk having a groove and an eccentric for project ing and withdrawing plungers in a loaf or bread cutter is not new.

No claim is herein made, rst, for a jumble or bretzel machine having one of its cylinders or dies provided with a cone for discharging to one side scraps of dough resulting from the formation of the bretzel, nor, secondly, the combination, with the cylinder of a bretzel or jumble machine, of the internal cone with its smaller end disposed at the open side or end of said cylinder.

Having thus fully described our invention, we claim and desire to secure by Letters Patent- 1. In a bretzel or jumble machine, a cylinder having two inner cylinders, one arranged,

within the other, the inner one acting as a weight to expel the dough, and the other one to guide and withdraw the studs, substantially as shown and described.
