This invention relates to an apparatus for 1 pressing out quantities of bakers material of the consistency of icing, dough or pasty material through a nozzle. The invention 5 includes smooth rollers which convey the Inaterial from a hop er into a small discharge chamber, and a p ate slidable in a rotatable spindle .for controlling communication between the hopper and the chamber. The material is then forced through outlet openings of a peculiar shape and structure onto a conveyor, the forcing being acomplished in such a way as to affect the delicate materials as little as possible.

This ap lication is a division of my aplication N. 357,301, filed April 22, 1929. This application relates more particularly to that form of the invention in which the nozzles do not move, but are themselves shaped to give shape to the articles manufactured. The primary purpose of the invention is to rovide nozzles through which material may pressed out, the nozzles being so arranged that the shape is well preserved and that the thickness is uniform. More specifically, a

. template is provided crossed by a number of fine wires or supporting and division plates which act to preserve the shape of a large iece.

Another object of the invention is to provide a plate slidably mounted in a rotatable spindle, the spindle being located wholly out of vertical alignment with the nozzle, so that the bakers material is pressed out of the By this method the material, especially if light and flufiy, retains its nature much more consistently than if it is forced through a curved or tortuous path.

Other objects and advantages will appear in conjunction with the accompanying drawings which form a part thereof.

In Figs. 1 to 4, the hopper into which the material is fed is indicated at 2. In the lower portion ofthe hopper are feed rolls 3, 4, which rotate inwardly to feed the material into the lower or expression chamber 92. In one wall of the chamber is a rotatable spindle 106 in which is slidably mounted a blade 107.- This blade is operated by any suitable mechanism, for example that shown in the patent to Copland, No. 1,657,457, through the various positions shown in Figs. 1 to 4, to express material through opening 78 in which the nozzle is arranged.

In Fig. 1, the blade is shown at the beginning of the operation. The blade moves outward into the chamber (Fig. 2) to cut off the desired amount of material from that in the hopper.. The spindle then rotates (Fig. 3) to push the material out of the chamber 92. The blade is then withdrawn into the spindle (Fig. 4) and the spindle is restored to its original position. B repetition of these steps successive equal amounts of material are expressed.

An edge disk 108 is provided at each end of one of the feed rolls. This closes the ends of the space between the feed rolls. opening 78, is directlyv below the space between the ro'lls, and the spindle is set in one side of the chamber and is wholly out of vertical alignment with the opening. In this way the material is expressed from the cham- The her in the same direction as that in which it enters the chamber, thus damaging the sensitive material as little as possible.

Figs. 5 to 7 show the novel form of nozzles. Fig. 5 shows a nozzle plate having two outlets made according to the present invenfrom the following description when taken; tion. The left hand opening, or template, 96

is intended for the manufacture of a paste sion opening 98 of the template 96 is subdivided, and the inner solid portions are supported, by narrow supporting and division plates 99 into com artments 100. This construction is also adopted in the right hand opening, except that there are no solid portions and the compartments 100 fill the whole space 101. The dough introduced into the template is thus divided during expression into small pieces which, after passin the plates, will recombine on account of the swelling of the dough and the pressure of the cutting wire.

A cutting wire 60 or blade is passed beneath the nozzles when the proper amount has been extruded so as to cut off a piece of uniform thickness. The bridges 99 divide the dough into a number of closely adjacent portions as it passes through the die. The knife or wire cuts these portions at a point slightly below, but spaced from, the lower edges of the plates. The plates act to support the divided portions of dough individually against the pressure of the cutting wire, so that the usual distortion of the whole piece is reduced to a considerable extent and the thickness and shape of the piece is thus kept almost uniform throughout the whole piece. The edges of the bridges are set back from the bottom of the. die, and therefore from the plane of action of the cutting wire, so that the pieces will not be cut off individual 1y. This may be accomplished either by setting back the whole edge or by making the bridges with teeth or serrate as shown in Fig. 7. The slight space between the bridges and the cutting wire permits the individual pieces to reunite to some extent because of the natural swelling of the dough, and the cut ting wire also presses together the pieces so that they will be set down on the receiving tray in a coherent state, as a single unitary article. In this way, large pieces expressed from a die may be cut off without variations in shape or thickness.

- Preferably, an edge or flange 102 is pro vided aroundthe openings projecting as far as possible toward the inner walls 103. The

result of this is that the dough is subjected to substantially the same friction at all points of the opening. This causes less sticking,

- and there is less internal friction which would destroy the pores and make the dough unfit for baking.

The thickness of the core pieces 104 and of the flanges 102 is made as small as possible to reduce friction and to ensure a uniform expression of all the small sections of dough. Vertical or oblique walls extending the whole height of the mold and directly upward from the edges of the openings would produce considerable friction which would damage the dough and prevent uniform thickness The core pieces may, however, be arched as at 105, Fig. 7. In this case, a flange 106 is left around the arched portion.
