MACHINE FORQMAKING PRETZELS.

SPECIFICATION forming part of Letters Patent No. 653,060, dated July 3, 1900.

Application filed December 26, 1899. Serial No. 741,524. (No model.)

To aZZ whom, it may concern:

Be itknown that I, QHARLES Bnrz, a citizen of the United States, residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Ma'- chines for Making Pretzels, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to a machine for cutting and rolling pretzels preparatory to their.

being twisted into the desired forms and baked.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

, Figure I is a top or plan View of the machine. Fig. II is a View in side elevation. Fig. III is an enlarged vertical sectional view taken on the line III III, Fig. IV. Fig. IV is an enlarged view, in front elevation, of the upper part of the machine. Fig. V is an enlarged sectional view of fragments of the dough-rolling drum and the lowermost part of the curved pressure-plate. Fig. V1 is a view in side elevation of the dough-carrieractuating device. 'Fig'VII isan enlarged cross-sectional view taken onthe line VII VII,

Fig. VI. FigJVIII is a detail sectional view taken on the line VIII VIII,Fig. IV. Figs. IX andX are cross-sectional views of modified forms of the rim of the dough-rolling drum.

1 designates the base of the machine, and 2 the journalboxes mounted thereon, in which the main driving-shaft 3 is journaled. The shaft 3 is equipped with a driving-pulley 4, that receives a belt 5 (see Fig. I) and carries a spur-wheel 6.

7 designates standards mounted on the the rim of the dough-rolling drum 10 and supported upon adjusting-

screws

13, 14, and 15, seated in different parts of the standards 7 The screws 13 are set in the base of the standards 7. The screws 1 f are set in a cross-bar 7 connecting the standardsnear the bottoms thereof, and the screws 15 are set in a crossbar 7 near the upper ends of the standards. (See Fig. II.) By adjusting the

screws

13, 14, and 15 the curved pressure-plate may be moved to or from the rim of the dough-rolling drum 10, as desired, in order to create greater or less space between the dough-rolling drum and curved pressure-plate and also that where desirable such space may be created of greater dimensions at either the upper orlower part of the curved pressure-plate. Mounted on the standards'Z are a pair of uprights 16, that occupy a position immediately above the dough-rolling drum 10. Se cured to the uprights 16 is a guard-box 17, that is open at top and bottom. 1

18 designates a roller, of pliable material, such as soft rubber, the roller beingcarried by a shaft 19, mounted in' the uprights 16.

20 designates an endless carrier that travels on the pliable roller 18 over a supportingplate 21, fixed to the uprights 16 and aiso arranged on a roller 22.

23 designates a pair of angle frame-bars mounted on the base 1 and attached to exten-. sions of the standards 7. (See Figs. I and II.) Mounted on the frame-bars are journal-box frames 24, containing movable boxes 25, that receive the shaft of the roller 22, the boxes being adjustable by means of adjusting-screws 26, by which they may be moved to move the roller 22 to tighten the'endless carrier 20.

In the use of the machine the dough, prepared in strips, is placed on the endless car- 'rier 20 and is conveyed thereon to the locat-ion of the roller 18, passing under a smooth-.

ing-plate 27. (See Fig. III.) The driving mechanism of the carrier will be hereinafter described. 7

28 designates a sprocket-wheelon the driveshaft 3, that receives a drive-chain 29, leading to a sprocket-wheel 30 on a shaft 31, mounted in arms 16 projecting'from the uprights 16.

Fixed to the shaft 31 at the opposite end from the sprocket-wheel 30 is a disk 32. (Shown in detail in Figs. VI and VII.) In the disk 2 csaoco.

32 is an undercut groove 33, that --receives a block 34. Seated in the block 34 is a jam screw or pin 35, adapted to bear against the disk within the groom 33 to hold the block in a fixed position.

36 is a pitman-rod through one end of which the shank of the jam-screw 35 passes loosely. The opposite end of the pitm an-rod is pivoted to a rocker 37, loosely hung on the shaft 22 of the roller 22'. The rocker 37 carries a pawl 38, backed by a spring 39.

40 is a ratchet-Wheel fixed to the shaft 22 and with the teeth of which the pawl 38 is adapted to engage. shaft 31, propelled by the drive-chain 29, the disk 32 is rotated and the pitman 36 is opereratedto rock the rocker 37. As the rocker is moved the pawl 38 engages the teeth of the ratchet-wheel 40 and moves said wheel to im' part rotation to the roller 22,and consequently to the endless carrier 20 thereon. By this arrangement and operation of parts the endless carrier is moved intermittently to carry the dough placed thereon forward to the cuttingknife, which will be presently described. By moving the block 34 in the grooved disk 32 away from or toward the axis of the disk the length of stroke of the pitman 36 may be altered at will to cause a greater'or less movement ofthe ratchet-wheel 40 oneach forward stroke of the pitman and a consequently inprovided with eccentrics 44, each of which is loosely surrounded by a sectional collar 46. 4

(See Figs; III, IV, and'VIII.)' One member of each sectional collar 46 carries a stem 47, and each of the stems receives the connection of a coupling 48. Connected to the couplings 48 are links 49, provided with loops 50, (see FigzVIIL) that receive the ends of a bar 51, that carries a knife 52. The ends of the bar 51 are held from turning in the loops 50 by set-screws 53, set in the loops and adapted to bear against the ends of the bar. The bar 51 worksin Vertical guide-slots16 contained by the uprights 16. In the turning of the shaft 31 the pinion 42 is rotated'and meshing with the teeth of the pinion 43 imparts rotation to theeccentric-carryingshaft 44. As the shaft 44 turns the eccentrics 44 are carried thereby, and through the connecting-links 49 the knife 52 is raised and lowered to and from the carrier 20 in a'position above the pliable roller 18, asclearly seen in Fig. III. The stems 47, carried by the sectional collars 46, are offset from each other with respect to the axes of theeccentrics, so that first one end and then the other of the knife 52 is raised and lowered" to the carrier 20 to cause the knife to operate in" a shearing manner in cutting the dough passed thereunder by the carrier on each of its intermittent movements, as explained. As

On the rotation of the ed in the uprights 16.

the knife descends each time it cuts off a piece of dough fed forward on the endless carrier, and the dough falls through the open guard 17 onto the rim of the dough-rolling drum 10 and is. conveyed by the dough-rolling drum in the direction indicated by the arrow in Fig. III into the space between the dough-rollingdrum rim and the curved pressure-plate 12, whereby the pieces of dough are rolled to the desired shape and emerge at the lower end of the curved pressure-plate, where they are discharged onto the table 54.

55 designates a pinion on a shaft 56, mount- The pinion 55 meshes with the teeth of the pinion 41, whereby the shaft 56 is rotated. Carried by the shaft 56 is a wiper-blade 57, said wiper-blade being adapted to contact with the knife 52 in the turning of its shaft 56 for the-purpose of clearin'g therefrom any dough that mayadhereto the knife, the dough being thrown from the wiper-blade and falling onto thedough-rolling drum 10.

In order to remove any dough that may'ad 59 arranged in position to be struck by the wiper-blade 57 in its rotation, the wiper-plate being movably held by a spring 60, secured to the supporting-shaft 61, on which the wiperplate is mounted.

In Figs. IX and X, I have shown two modi fications of the rim of the dough-rolling drum 10,- the

rims

10 and 10 therein being provided with

circumferential concavities

10 and 10 instead ofhaving a flat circumference, as seen in Figs. III and V.
