SEIDEL, OF HALLE-ON-THE SAALE,

DOUGH-DIVID ING MACHINE.

SPECIFICATION forming part of Letters Patent N 0. 269,288, dated December 19, 1882.

Application filed October 1862. (X0 model.) Patented in Germany October 18, 1877, No. 640, and August 4. 1880, No. 15,145.

To all whom it may concern Be it known that we, FRIEDRICH HERBST and GUSTAV SEIDEL, both of Halle on-the baale, in the Kingdom of Prussia and Empire of Germany, have invented certain new and useful Improvements in Dough-Dividing Machines; and we do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention has for its object to produce a machine in which to divide a-lump of dough into multiple parts of equal weight for small bakings; and it consists of the novel devices and combinations of devices hereinafter described and specifically claimed.

In the accompanying drawings, Figure 1 represents a perspective view of the machine. Fig. 2 represents a vertical longitudinal seetion of the machine; Fig. 3, a vertical transverse section of the same; Fig. 4, a detached partial section and plan of the table and cutter-frame; Fig. 5, a plan view of the machine; Fig. 0, a side elevation,.and Fig. 7 an end elevation, of the machine; and Fig. 8, a plan of the cuttenfraine and follower-disk.

Corresponding letters in the several figures of the drawings designate like parts.

The frame consists of a cylindrical table, A, that has square flanges to its top and bottom edges, and is bolted upon two stands, B and B, each composed of two corner-posts that are connected by cross-braces, and both stands are connected again at their base by a tie-rod, a, and screw-nuts b. Under the middle portion of tableAis bolted a saddle-plate,0,having an eye in its center, which is bored out to form the guide for a vertical bar, (I, that, with its upper flanged head,is secured to the bottom of a disk, D.

A cutter-frame, E, is formed of a series of sheet-metal rings, 0 and c, that are concentrically connected byradial sheet-metalplatesc, in a manner to form a multitude of openings of equal area that have vertically-parallel sides. The external edges of the radial plates 6 are downwardly extended and fitted into grooves in the upper inner face of cylindrical table A in a manner that the cutter-frame E stands above table A and is rigidly supported thereon. The inner ring, 0, of the cutter-frame E is sustained besides by four rods,f, that are either slitted on top for inserting the cutterringedge, or have said cutter-ring edge secured through holes in disk D, and, with their lower screw-threaded ends, are inserted into holes in a ring, 9, that is fitted over the eye-hub of saddle-plate 0, and are adjustably supported thereon by double nuts It. The' disk D, that "ertically moves in the cylindrical opening of table A below cutter-frame E, has secured upon its top'face a series of followers. 43, the upper faces of which are titted snugly into the openings of the cutter-frame, so as to slide therein, and when raised to their uppermost position to form a perfectly level and smooth surface with the upper edges of the cutterplates. The lower end of bar (I is pivotally connected by linksj with the crank K of shaft F, that is mounted in journal-boxes of stands B and B, and upon the overhanging end of which shaft is secured a hand-lever, G, that has an arm, H, for a counter-weight, I. This arm H has secured a toe-plate, Z, which will strike upon a bracket, m, of stand 13' for 'preventingthet'ollowerstfromrisingabove thecutter-frame E, and a cushion may be attached will make the striking of these parts noiseless. The counter-weight I is to be heavy enough not only to raise and hold the followers 1' to their uppermost position, but such counterweight is to exert a suflicient overpressure to ers before yielding.

A ring, L, is bored out to tit snugly over the cutter-frame. This ring L, by two rods, M, that are guided in lugs or flanges n of stands B and B, is rigidly connected with yoke N, the center of which is bored out to slide upon rod d. Two bolts, 0, with slotted eye-heads, are passed through holes in yoke N, intermediate of rods d and M, and are secured by screw-nuts, and barsp are pivotally connected with one end to bolts 0, and with their opposite ends to crank thereto in any suitable manner, are passed either to such toe-plate l or to bracket m, that require a considerable force upon such followv q of shaft 0. This shaft 0 is mounted injournal'boxes of stands B and B, and has rigidly secured upon its overhanging end a long handlcver, T, which, being turned toward the left, will raise the yoke N and ring L.

Upon one/end of ring-L are cast two eyelugs, 'r, to which are pivotally connected by a fulcrum-bolt, s, the hinge extensions of the cover I. This cover I has a flat and smooth bottom face that will form a closejoint with the top of ring L, and has an arched top, and, for combining strength withlightness, itis cast hollow. To its front end the cover I has secured a latch, t, which will engage witlra hook, u, that forms part of a. short shaft, V, pivoted in eye-lugs that are rigid with ring L. A crankhandle, 2:, is mounted upon one end of shaft V, and a leaf-spring, w, is secured against the edge of ringL, that holds the hook it in engagement with latch t. For opening the cover the hook at is turned away from latch t by depressing the handle V.

A spring, Q, secured against the rear edge of ring L, is coiled around the fulcrum-bolt s, and is thence extended to reach over the front end of the cover, where a hook bent to its end is coupled by a short chain, 90, to a book, 3 that is secured to the cover P. This spring Q will raise the cover as soon as the latch is released, and will strike and hold it against cushioned standards It in a nearly vertical position. A knob, S, is secured upon the front end of cover P, by which to push the cover down upon the ring for closing it.

The disk D has a series of perforations for any particles of dough to drop through that might work past the followers i.

The operation of the machine is as follows, to wit: The machine being in position, as shown by Fig. 7, with the cover P thrown open andthe followers 2' in their uppermost position, so as to be flush with the upper edges of the cutter-frame, a lump of dough of the desired weightis placed centrally upon the cutter-frame E. Now, by grasping the lever T and by pushing it toward the left the ring L is raised until its upper surface reaches above such doughlump, when the cover is turned down upon its seat, where it will be automatically locked by the hook it and latch t. Next, by releasing the lever T and then by pullingit to the right the dough will be firstpressed out uniformly to fill the space inside of ringL between the cover P and followersi,to be formed intoacircular cake of equal thickness, and then by further pressure that will overcome the resistance of counterweight I the followers 5 will sink down between the cutters proportionally as the cover P approaches the cutter-frame, and the dough will be pressed into the several compartments between the cutters. As soon as the cover P is brought down to bear upon the cutter-frame the cover I? is to be released from latch-hook n and will fly open, when the counter-weight I will push the followers 27 upward to regain their original positions, and will raise the divided dough to the surface. After the dough-pieces have been removed another lump of dough is put into the machine to go through the same operation, and so on until all the dough is divided.

The hand-lever G is for lowering the followers when the cutters are to be cleaned, or for giving an additional counter-pressure to that brought about by counter-weight I when a very small lump of dough or very stiff dough is to be divided, to insure its uniform spreading over the entire surfaces of the cutter-frame before the followers are to yield.

By the above-described arrangement of compressing the dough between the cover and followers that are-both vertically movable, and ofdividing it by stationary cutters that are forced through the dough while thus compressed, a very accurate dividing is accomplished, and the dperation is accelerated to a great extent.

As will be noticed, the machine is very simple and compact in its construction and durable in all its parts.
