SHEAR-MOTION CONFECTIONERS MOLDER O R PRINTER.

SPECIFICATION forming part of Letters Patent No. 699,687, dated May 13, 1902.

Application filed June 15,1901.

To all w7t01n it may concern.-

Be it known that I, HORACE O. KELLOGG, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Shear-Motion Confectioners" Molders or Printers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

Various kinds of confectionery are shaped and ornamented in molds formed in material like powdered starch. This material is held in a box, the molds impressed in its upper surface by dies, and the confectionery in a fluid state poured into the molds.

The purpose of this invention is to provide a simple operative device for forming these molds; and the invention consists in a frame having a support for the mold-box and an attached vertically-moving hand-operated lever, which carries the dies for forming the molds upon its under surface in inverted position, has a vibrator for vibrating the dies, is moved downward by hand to make the impressions, and is automatically returned to its highest position and held normallyin such position.

The invention further comprises means for the adjustment of the die-holder upon the lever and for securing the die-holder to the lever. r

In the drawings, Figure l is a View in plan of the machine. Fig. 2 is a View in plan of the mold-box in the machine with the die or former board and operating-lever removed. Fig. 3 is a view in vertical section upon the dotted line 3 3 of Fig. 1. Fig. 4 is a View in cross vertical section upon the dotted line 4. 4 of Fig. 3.

Referring to the drawings, A is a frame, preferably of wood. It has at its top the cross-supports a, upon which the mold-box B rests when in operative position, the box sliding from the front (2 of the frame horizontally into. and out of said position. Adjustable stops 7) limit the extent of its backward movement, and a side rail ct and a laterally-adjustable guided limit the crosswise movement of the box. The end stops and the side guides also permit the employment of mold-boxes varying in size.

' therein.

Serial No. 64,767. (No model.)

The mold-box is filled with powdered starch b or other formative material. Below the mold-box is a pan 0, slidable from the front of the frame upon the supports a into and out of position. Its office'is to receive any material which may drop from the mold-box.

D is the lever for holding the dies or formers d and for moving them vertically with respect to the mold-box B and the material This lever is pivoted at d at or near the rear upper corners of the frame and ex tends forward over the mold-box and has at its front end a handle d by means of which it is moved downward. Its normal inoperative position is represented by dotted lines in Fig. 3. The position represented by full lines in said figure is that which it and the dies or formers occupy at the end of their downward movement into the material in the mold-box. The lever is formed to permit the placing and removal of the die-board d the side bars 01 of the lever having grooves (1 which receive tongues (l on the side edges of the die-board, and the lever is further so shaped that the die-board may be placed and removed from the front of the machine without interference with the handle (V. The dieboard holder in the nature of bars (2 of the lever are adjustable with respect to the side arms 01' of the lever to permit of the vertical adjustment of the die-board. This is accomplished by mounting the bars 61 upon the lever-arms d and by connecting them with the arms by means of an adjustable connection which will permit the vertical movement of the bars with respect to the arms. I have represented for accomplishing this purpose bolts d carried by the bars d, which extend through vertical slots (1 in extensions of the arms 01 and which bolts are adapted to receive nuts which look them and the bars to the arms. By loosening the nuts the bars may be adjusted upon the arms of the levers to any required extent, thereby adjusting the position of the die-board. In making the adjustment the nuts are loosened, the die-board closes upon the mold-box, and the nuts then tightened to lock the bars to the lever. It will thus be seen that the lever has a'holder for the die-board which is adapted to removably hold the die-board and is also adapted to be adjusted vertically withoutinclining it unless desired.

The die-board is locked to the lever by means of locking pins @1 which extend through holes in the side arms into holes in the tongues of the die-board.

E represents strikers which are operated to jar the die-board and dies. They are mounted, as represented in Figs. 1 and 3, at the inner end of the spring-arms e, and these arms extend backward from a common shaft 6, mounted upon the lever-arms d. A spring c is secured to the shaft and one arm of the lever to impel the strikers against the die-board, and a handle 6 extends from the shaft to a position near the lever-handle 01*, whereby the hand which moves the said handle d may also move downward the handle 6 and thus lift the strikers. The release of the handle 6 permits the spring to move the strikers with any desired stress against the holder of the die-board, and this release generally takes place at the end of theimpressing movement of the dies or formers.

In operation moldboxes filled with the mold-forming material are fed in successive order by sliding from the front of the machine upon their support. As each one is placed in position the lever is moved downward by hand and the dies or.formers which it supports are forced into the material in the box and at the same time the dies or formers are jarred by a release of the strikers.

The hand is then removed and the lever and dies or formers are automatically moved upward by the spring D, which is expanded by the downward movement of the lever, and this spring also serves to hold the lever and dies or formers in their-highest position and removed from interference with the mold-box.

It will be seen that the shear movement of the dies or formers with respect to the moldbox embeds the dies or formers into the starch in a peculiar way, in that those which are at the rear of the board strike the starch slightly in advance of those which are in front of it and the release of the dies from the formed molds is the reverse of this action. This accomplishes two advantages, one of which is especially important. It enables a lighter pressure to be employed, because the compression action is in the nature of a gradual and an advancing one rather than an instantaneous one, and it also permits the dies to be removed from the molds without injuring them, because the movement of each die from its mold has something of a tipping motion, whereby one edge is freed slightlyin advance of the other, thereby allowing the air to enter the mold and doing away with the suction which is inherent upon a straight movement of the die from the mold.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States- I 1. In a machine of the character specified, the combination of a mold-box for holding formative material, a lever, a die-board carried by the lever having dies or formers, and means for vertically adjusting the die-board upon the lever without changing its inclination.

9. In a machine of the character specified, the combination of a frame, a mold-box for holding formative material mounted upon the frame, a lever attached to the frame and extending over the mold-box and having a shear motion relatively thereto, a die board carrying dies or formers mounted upon said le=- ver and movable thereby toward and from said box, and means for automatically moving said lever and said die-board upward automatically, and for holding them removed from the mold-box.
