Substitute for application Serial No. 295,009, July 24, 1928. This application April 30, 1934, Serial 7 Claims,

My invention relates to the method and apparatus for cutting and wrapping butter and the like, and particularly relates to cutting and wrapping butter in pieces suitable for serving in in- 6 dividual portions.

The object of my invention is to provide a method of cutting the butter into small portions and separating the portions by inserting folds of paper between the same; a further object is to provide a wrapper for the block of butter, which latter is out into individual portions and the wrapper is so formed that folds of the wrapper will separate the portions while the shape of the block of butter is retained by the wrapper; a still further object is to provide a wrapper for Yseparating the portions of butter by a continuous strip of paper havngfolds positioned between the portions whereby the strip of paper may be extended by pulling upon the 26 ends thereof when it is desired to separate the portions of butter; and a still further object is to provide a suitable apparatus for carrying out my novel method of cutting and wrapping butter, which will be more fully hereinafter described and claimed. y

Referring to the accompanying drawings Fig. 1 is a plan view of one form of apparatus adapted for carrying out my invention; Fig. 2 is a vertical section on line 2-2 Fig. 1;v Fig. 3 is an end elevation of Fig. 2; Fig. 4 is an enlarged plan view of oneV portion of the apparatus, shown in Fig. 1, illustrating another step in my novel method of wrapping butter; Fig. 5 is a perspective view of a block of butter cut into individual portions and encased in. my novel form of wrapper; Fig. 6 is a plan View of a wrapper formed of two strips of paper for encasing the individual portions of butter; and Fig. 7 is a still further modiication of my invention in which the folds of the strips of paper extend to the center line of block of butter instead of entirely through the block.

In the drawings in which like reference characters refer to like parts 1 represents an apparatus for carrying out my invention and comprises a bed plate 3 on which is secured a guide 2 formed by plates 4 and 4' between which a block of butter 6 is adapted to be advanced by a movable tray 8, having a handle 9 for moving the tray. A push plate 10 is secured to the tray and is adapted for moving the block of butter between the

guides

4 and 4. Said guides 4 and 4' are in alignir^nt with

guides

12 and 13 and have transverse vertical spaces or openings formed between the sections of the guides for the passage of the

knives

18 and 20 located upon opposite sides of the guides and slidably mounted in

bearings

21 and 22 secured upon the bed plate 3.

Blades

23 and 24 for folding the paper 25 are 00 mounted in

vertical bearings

26 and 27, extending parallel with the

guides

4 and 4 and at right angles to the

cutting knives

18 and 20. The

bearings

26 and 27 Yfor the

folding blades

23 and 24 are provided with adjustable stop-screws 30, @5 against which the stop-plates 31 on the blades strike for limiting the movement of the latter. The

bearings

21 and 22 for the

cutting knives

18 and 20 are also provided with stop-screws 32 which engage stop-plates 33 mounted upon the 70 knives and are adapted for limiting the distance the knives may enter the block of butter 6.

Springs

35 and 36 having one end secured to the

bearings

26 and 27 and the opposite end secured to the

blades

23 and 24 respectively, are pro- 75 vided for withdrawing the blades into a normal position, in which the blade 24 is shown in Fig.

1.

Similar springs

37 and 38 are provided for withdrawing the

cutting knives

18 and 20 to the normal position, shown in Fig. 1. Upon the 30

guides

12 and 13 are provided

pockets

40 and 41 to receive the ends of the

folding blades

23 and 24 when they are advanced, to the position which the blade 23 occupies in Fig. 1.

The tray 8 is provided with aseries of holes 45 S5 extending lengthwise thereof, and the guide 2, formed by the

plate

4 and 4 is provided with a pin 46, shown in Figs. l and 2, which pin is adapted to enter the holes 45 in the tray and hold the tray from moving when the cutting knives are being inserted in the butter. The tray 8 may be lifted by means of the handle 9 sufficiently to Withdraw the pin 46. from the holes 45 and allow the tray to be advanced step by step according to the distance between said holes, thus ensuring a uniform size of all the individual portions 7 when cut.

The apparatus shown in Fig. 1 is a double machine adapted for using two strips of paper 5, or it may be operated by using only one strip of paper, as shown in Fig. 1 of the drawings.

For the purpose of illustrating one form of wrapping butter, only the lower portion of the machine shown in Fig. l will be included in the following description of the method for forming the wrapper shown in Fig. 5. A strip of paper 5 is inserted into the verticalV opening, or slot 15, formed between the two

sections

4 and 12 of the guides. A block of butter 6 is placed in the guide 2 in front of the plate 10 and the tray advanced 110 I to a point where it is desired to have the knife 1'8 enter the butter and cut the block transversely to form an individual portion '7. 'I'he folding blade 23 is now advanced into the position shown in Fig. l, so that the blade 23 will force the paper into the pocketO, thus providing sufficient slack in the strip of paper to allow the cutting knife 18 to be advanced into the butter carrying the strip of paper simultaneously with the knife. The cutting knife 18 is advanced the full width of the block of butter, then the knife is withdrawn leaving the folded paper positioned between the block 6 and the portion '7.

The tray 8 is again advanced to a position for the cutting knife to make the second insertion into the block of butter. These operations are repeated until the entire block of butter is cut into individual portions, thus forming the wrapped package, illustrated in Fig. 5.

The wrapper, as illustrated in Fig. 5, consists of the strip of paper 5 which is formed with the sections 5a and 5b folded upon themselves and positioned between the portions '7 of the butter, thus separating the latter by two thicknesses of paper. The strip 5 is about the width of one side of the block of butter and thus covers one side of the block of butter after it is cut into the portions 'l. A single thickness 5c of the strip 5 extends over the extreme end portions of the block and projects beyond the same a sucient distance to permit the ends of the strip to be readily grasped between the fingers and pulled lengthwise to straighten out the strip, so that all the separate portions rI of butter will be distributed and lie fiat upon the strip of paper throughout the length of the latter, from which the portions may be readily removed for serving.

Fig. 6 illustrates a wrapper in which two sheets of paper and 56 are used. Said strips are nserted or applied to the block of butter by the entire apparatus shown in Fig. 1. One strip of paper being located on one side of the block of .butter and the other strip located upon the opposite side thereof. By operating the

cutting knives

18 and 20 alternately, as the tray 8 is advanced, and also operating the

folding blades

23 and 24 to provide said strips with sulcient slack to form the folds 55a and 56h, the block of butter will be cut into individual portions with the folded portions 55a and 56h, of the two strips of paper, inserted between alternah portions of the butter.

Fig. 'l 'illustrates a form of wrapper in which two strips of

paper

60 and 61 are used and the folds 60a and 61h are extended only to the center line of the block of butter. The wrapper shown in Fig. I may be readily formed upon the apparatus by adjusting the stop screws 30 to suitable positions which limit the movement of the

folding blades

23 and 24 so that when said blades are operated the stripsof paper will be folded into the pockets only ya sumcient distance to form enough slack in the paper to provide for the insertion of the

cutting knives

18 and 20 as far as the center line of the block of butter. Incarrying out this form of my invention the

knives

18 and 20 are operated simultaneously until their forward edges meet the center of the block of butter. When the knives are withdrawn the tray is advanced to the next adjacent holes in the tray when both cutting blades are again inserted into the butter carrying the folds of paper into the butter. These operations Aare repeated throughout the length of the block of butter.

In al1 the forms of my invention illustrated in Figs. 5 to I the strip of paper forming. the wrapper is of the width equal to the width of a block of butter and is intended only to cover one edge and the sides of the individual portions. When two strips of paper are used as shown in Figs. 6 and 7 the opposite edges of the butter are covered by the paper. To' remove the cut portions of butter from the paper it is merely necessary to pull the ends of the paper to straighten out the folds and the pieces of butter will arrange themselves in spaced relation to each other throughout the length of the strip, from which they may be rapidly removed when it is desired to serve said portion of butter.

Various changes may be made in the Wrapper and in the apparatus for applying the wrapper, other than those shown in the drawings without departing from my invention.

This is a reled application, and is substituted for my abandoned application No. 295,009 which was filed July 24, 1928.
