Serial No. 539,169.

This invention relates to pie making machines and a matrix therefor, also to a new process for lining multi-unit pie molds. The machine and matrix are particularly adapted for use in the process of making die stamped or molded sector shaped individual sealed ies. p One object of this invention is the quick lining of a pie mold.

Another 'object is to reduce the cost of manufacturing stamped or molded sector shaped individual sealed pies.

Another object is the production of a better sector shaped individual sealed pie.

Other obj ects will appear from the detailed description which follows.

In the drawings comprising two sheets of 10 figures numbered Figures 1 to 10 inclusive, one embodiment of the apparatus is set forth.

Figure 10 is a horizontal cross section of the matrix stem and certain associated parts in plan taken along the line 10-10 of Figure 8 looking in the direction of the arrows.

Like reference characters designate corresponding parts throughout the several figures of the drawings.

The apparatus consists essentially of a matrix for pressing the lower layer of dough into the sector shaped receptacles of a multi unit mold to line the same; and a work bench or table for supporting the mold, having mechanism for bringing the matrix and mold into correct registry to eifect said dough lining operation.

The table may consist of a plurality of supports 20-21 strengthened by means of a suitable cross piece 22 and carrying a table or bench top 23. A suitable bracket 24 is secured to said table top by suitable screws -or rivets 25-25. Arm 30 of the bracket 24 may be further re-enforced by suitable re-enforcing members 26-28 whichk are secured to the table by suitable screws or rivets 27-29. An extension arm 31 is secured to bracket 24 in spaced parallel relationwitli respect to the arm 30, and the

arms

30 and 31 are further braced by means of the cross piece 32. The bracket 24 is extended by means of the extension arm 33 which pivotally supports the lever arm 34 at 35. A lever 40 having a foot rest 41 is pivotally supported by the table as at 39 and levers 34 and 40 are pivotally interconnected at'36 and 38 by means of a connecting rod 37 so that whenever lever 40 is depressed by the application of foot pressure to foot rest 41 that arm of lever 34 which is pivotally secured to connecting rod 37 moves upwards and the other arm of lever 34 moves downwards.

The matrix stem 46 is slidably mounted in arms 30 and 3l and is provided with an eye 43 at its upper end to permit the insertion of lever arm 34 therein to translate the swinging movement of the lever into the downward thrust of matrix stern 46. A roller mounted on a spindle 54 supports lever arm 34 within the eye 43. A collar 56 is secured to the matrix stem 46 by means of pin 63. Mounted upon the matrix stem 46 between arm 30 and collar 56 is a coiled spring 45 tending to retain the matrix stem in its upper (normal) position.

The matrix stem 46 is partially flattened at 57 throughout a portion of its length (compare Figures 8 and 10) thereby forming centering means which co-acts with the plate 58 to prevent improper adjustment of the matrix stem. Plate 58 is adjustably secured to arm 31 by means of set screw 59.

The matrix 47 is secured to the collar 60 of matrix stem 46 by means of suitable screws 61. This matrix is shaped to conform to the shape and internal configuration of the lower mold or pie pan 49 which may be of any preferred form or size but which is preferablydcircular in shape to conform to the conventional pie pan. Mold 49 is subdivided into a plurality of sector shaped' recesses 5252 as indicated in Figures 5 and 6 and matrix 47 is provided with a plurality of elements 48-48 conforming in shape and substantially conforming in size to the recesses 52 in the mold 49, the elements 48 being slightly smaller in size than the recess 52. the ditl'erence in size being substantially equal to the ultimate thickness of the layer ot dough 53 (Figure 6), so that whenever the elements 48 of matrix 47 are brought into correct registry with the recesses 52 of the mold 49 the lower layer of dough 53 will be snugly pressed against the walls of the recesses 52 to form a lining for, and faithfully conforming to the shape of, the recessed mold.

To facilitate the correct positioning of the interchangeable mold 49 with respect to the matrix 47 'so as to permit the elements 48 of the matrix 47 to correctly register with the receptacles 52 of the mold 49 centering means is provided which may consists of a plurality of projecting ribs 50-51 disposed at a suitable angle (for example, right angles) to each other. These ribs are secured to the surface of the table top 23 and are arran ed to intersect at a point perpendicularly eneath the central point of the matrix 47. The

ribs

50 and 51 are shaped to snugly fill the channels 62 formed between the undersides of the radial walls of the sector shaped receptacles 52 of the interchangeable mold 49 so that when said mold is placed upon the table in such a position that its intersecting channels 62 register with the intersecting

ribs

50 and 51 it will be in a correct position to register with the elements 48 of the matrix 47 when the latter descends under control of the matrix stem 46.

The method of operation is as follows:

After the operator has covered one of the interchangeable molds 49 with a sheet of dough the mold is quickly placed upon the table in position to permit the intersecting

ribs

50 and 51 to register with the intersecting channels 62 upon the underside of the mold. The operator now applies foot pressure to the foot pedal 41 causing lever 40 to swing about its pivot 39 thereupon causing connecting rod 37 to move in an upward direction and swing lever 34 about its pivot End 44 of lever 34 swings in a downward di rection forcing the matrix stem 46 downwards against the ever increasing tension of the coiled spring 45. Matrix 47 carried by stem 46 likewise moves downwards until the several elements 48 register within the several recesses 52 of mold 49 pressing the dough 53 against the 4walls of the mold until the dough assumes the configuration of the mold and lines the walls thereof to constitute in effect the foundation or lower layer of dough of thc partially formed pie. Upon removing pressure from foot pedal 41, coiled spring 45 forces the matrix stem 46 upwards until the shoulder of collar 60 abuts against the underside of arm 31 preventing further upward movement of stem 46 and restoring the machine to normal.

The dough 53 may thus be very quickly and accurately positioned in the mold and as the entire operation is completed instantaneously much time and labor is saved so that the operator is able to make pies much more rapidly than would be the case if it was necessary for him to perform the operation manually, whereby the production cost of die stamped or molded sector shaped individual sealed pies is very materially reduced, and this saving can in turn be passed onto the customer.

By the use of a matrix in this manner the pies when formed will be uniform in appearance and attractive to the buyer.

Obviously the form of the lever mechanism employed to operate the matrix can be modified in many ways without departing from the spirit of the invention.
