BUTTER-CUTTER.

Specification of Letters Patent.

Patented Nov. 17, 1908.

Application filed. April 13, 1908. Serial No. 426,706.

To all whom it may concern:

Be it known that I, JENS N. JACOBSEN, a citizen of Germany, residing at Eureka, in the county of Humboldt and State of California, have invented new and useful Improvements in Butter-Cutters, of which the following is a specification.

This invention relates to an improved ma chine for cutting butter, or other material of similar consistency, the object of the invention being to provide a machine of this character by means of which the entire operation can be performed in a single continuous movement of the cutting mechanism, in which the force applied to said mechanism is employed in the most advantageous manner possible, and in which all the parts are readily accessible so that the machine can easily be maintained perfectly clean.

In the accompanying drawing, Figurel is a side View of the butter cutter in its initial position; Fig. 2 is a similar view showing the parts in the position when the horizontal cut has just been completed; Fig. 3 is a per spective view of the follower; Fig. 4: is a side view of the machine showing the parts when the vertical cut has just been completed; Fig. 5 is a broken end view of the machine showing the parts in the position corresponding to Fig. 1; Fig. 6 is an enlarged detail broken longitudinal vertical section of the machine; Fig. 7 is a perspective View of the block of butter divided into sections.

Referring to the drawing, 1 indicates a metal plate supported upon legs 2. Said plate has a transverse upwardly directed rib 3 which has formed on one side thereof semi-circular lugs 4t, around which extend the vertical courses 5 of a zig-zag cutting wire 6, which also extends around circular lugs 7 formed on the side of a transverse bar 8, said wire 6 being secured at its ends to screws 9 on said bar 8. Said bar 8 forms the top side of a rectangular frame comprising also posts 10 formed integral with said plate 1. The several courses 5 of wire operate as individual wires, and their function is to divide longitudinally and vertically the block of butter into slabs. Secured to screws 11 on the posts 10 is a horizontal'wire 12, which horizontally and longitudinally divides said slabs in the middle.

Supported upon the plate 1, on opposite sides of the rib 3, are table sections 13, upon which can slide a block of butter, shown in dotted lines at 14;. To begin the cut, said block is placed upon the rear table section in abutment with a follower 15, the latter being secured to a follower plate 16, having sleeves 17 in which are secured guide rods 18, which rod can slide in bearings 19 formed in the plate 1. l

Secured upon the back of the follower plate is a transverse bar 21, the end of which enter cam slots 22 of arms 23 of levers 27 secured upon the ends of a shaft 24 extending transversely beneath the plate 1 and having bearing 26 formed on said plate. Said shaft 24 and both of the levers 27 can be moved in unison by means of either or both of two handles 25 secured at the ends of the arms 23. The cam slots 22 are eccentric to the shaft 24 so that by moving said levers 27 forwards, in the direction from the position shown in F ig. 1 to that shown in Fig. 2, the bar 21 forces the follower 15 to advance the butter over the table sections 13, and thus presses it between the courses 5 of wire, and above and below the wire 12, so that, by this horizontal movement, the butter is cut vertically and horizontally into slabs. When said levers arrive at the position shown in Fig. 2, said wires have passed longitudinally entirely through the butter, and are then received in slits or grooves 28 formed in the face of the follower. It is now necessary to divide the slabs thus formed each into two, by a vertical cut through the center. This is effected by means of a trans verse wire 29 secured at its ends in vertical slide rods 30 connected at top and bottom by transverse bars 31, and guided vertically in guides 32 also formed integral with the plate. The ends of the lowest transverse bar 31 are extended, as shown at 33, to enter cam slots 34 formed in arms 35 of the cam levers 27. lVhile the horizontal cut was taking place these ends 33 were contained in parts 36 of said slots 34: concentric with the shaft 2-1, so that the frame, consisting of the slide bars 30 and transverse bars 31, was maintained in its raised position, the cutting wire 29 being then above the level of the top of the butter. But, when the ends of the bar 21 arrive at the ends of the eccentric or working portions 22 of their slots, then the ends 33 of the lowest bar 31 also arrive at the ends of the idle portions 36 of the corresponding slots 34 and enter the eccentric working portions thereof. The continued movement of the levers 27,.from the position shown in Fig. 2 to that shown in Fig. 4, now, by the pressure of the upper sides of the slots 34 against, the ends of the lower bar 31, depresses said 31, so that the cutting wire 29 passes vertically through the mass of butter, dividing the slabs into halves. During this movement the follower is maintained stationary by reason of the ends ofthe bar 21 being now contained in parts 37 of the slots 22 which are concentric with the shaft 24.

The advantages of the invention are the simplicity and cheapness of the construction; the convenience of operation, since the entire operation can be performed in a single continuous movement; the efficiency of the machine, since the force applied to the machine is utilized in the most advantageous manner possible; and the fact that all of the parts are so placed that they can readily be maintained perfectly clean.

I claim 1. A butter cutter comprising a table for I the butter, a lever pivotally connected with said table, a wire for cutting the butter, a follower for pressing the butter against the wire, and a device carried by said follower and movably engaged by said lever, to move the follower and press the butter against the wire, substantially as described.

2.
