materials, such for example as cheese, [butter and the like, although it is not limitedto slicing such materials but may be used for slicing various other materials such as bread, meat and the like.
It has for an object to provide an improved slicing device which will make clean slices in slicing such soft material as cheeses and the like and in such a way as to prevent the material clinging to the knife.
Another object is to provide a simple and effective arrangement whereby the cutter or knife is a thin, flexible blade mounted so that in the slicing operation it is drawn longitudinally through the material to be sliced and at the same time is moved laterally or at right angles to this movement through the material.
With the foregoing and. otherobjects in view I have devised the construction illustrated in the accompanying drawing forming a part of this specification, the showing being somewhat diagrammatical. It is, however, to be understood the invention is not limited to the specific construction and arrangement shown, but mayembody various changes and modifications 'within the scope of the invention.
In these drawings:
Fig. 1 is a vertical transverse section through the device;
Fig. 2 is a detailed section substantiall on the line 2--2 of Fig. 1, but on a larger scale;
Fig. 3 is a section substantially on the line 3-3 of Fig. 2;
Fig. 4 is a section substantially on the line 4--4 of Fig. 3; r
Fig. 5 is a detailed section substantially on the line 5-5 of Fig. 1,
Fig. 6 is a transverse section through one form of blade which may be used, the shape of the blade being, however, exaggerated,
Fig. 7 is a side view of the device looking from the right of Fig. 1, and
Fig. 8 is a plan view of the casing enclosing the blade wind-up means, the guide for the casing and the threaded rod being shown in section.
In slicing various articles, such for example as soft cheeses and the like, it is very diificult to make clean slices and to prevent the material clinging to the knife or cutter. Even the fine wire cutters now generally employed are not satisfactory. In the present device I have greatly reduoed these difficulties by using a thin, narrow, flexible blade or cutter and mounting it so that it will simultaneously have two different movements through the material, One being a. move-l ment, transversely of the material and longitudinally of the blade, and the other a movement laterally through the: material in the plane of the blade and at substantially right angles to the first movement. These combined simultaneous movements have been found to give a much cleaner out with less liability of the material clinging to the blade, and make it possible to secure clean, thin slices even of soft material such as cheese and the like.
It will be understood the device may comprise various constructions and arrangements, the showing in the drawing being somewhat diagrammatical, and the device is not limited to the 1.5 specific; construction and arrangement shown.
The, device illustrated comprises a frame or base Hi which is. a slidable support or platform II to carry a loaf or block [2 of cheese, butter, bread or any material which is tobe sliced, the platform It being guided for sliding feeding movements in suitable guides l3, and it preferably has an upstanding flange M at one. end to hold the unaterial [2 in place. Means is provided for giving a feeding movement between the material 12 and the cutting knife. In the device illustrated the platform H and the material I2 is fed forwardly in, a step-by-step movement to permit cutting of successive slices from the material I2 and at the proper thickness. Various feedin mechanism may be used. That shown comprises a rack 15 secured to the platform ll meshing with a small pinion 16- on a transverseshaft l1. Mounted on this shaft is a ratchet I8 which may be given partial successive rotation by means of a pawl 19 pivoted on a reciprocating rod 20 mounted in a suitable bracket 20a. It may be operated by a push button 2| with a spring 22 tending to return the push button and the pawl to their normal position. An adjustable stop 23 may be pro- 40 vided to determine the downward movement of the push rod and the pawl and thus adjust the feeding movement of the platform It and determine thethickness of the slices cut from the block or loaf I2.
Forcheese and similar materials, the cutter preferred comprises a flexible, thin, narrow blade 24. This may be flat, but for these soft materials it may be slightly curved transversely so as to be concavo-convex, as shown in Fig. 6. It is preferably similar to a steel hairspring, with a razor edge 25 on its lower or cutting edge, or if preferred, for certain materials it could be a toothed edge. It may be of different widths depending on the material to be cut, but for cheese and similar material it is preferablyof the order of. about T g inch wide and verythin. This thin flexible blade is connected at one end to a member 26 which is mounted so as to rotate to wind and unwind the flexible blade on and from it, and at the same time to move laterally, in the present case vertically up and down, so that the flexible blade has two simultaneous movements. In the present arrangement the member 26 is a sort of nut or drum on which the blade 24 may be wound, as shown, and it also has threaded engagement with an upright threaded rod or screw 21. This rod has threads of a relatively long pitch so that as the member 26 rotates it will move longitudinally up and down. The threads may be of thetype used in the well known Yankee drills in which a rod provided with a long pitch spiral groove and carrying the drill chuck is driven by reciprocating a nut threaded on the rod. This rod has a noncircular or squar lower end 28 mounted in a similarly shaped recess in the base Ill so that therod 21 is held against turning movement.
' The nut or member 26 is mounted in a casing 29 with a coil spring 35 connected at one end to the member 26, as shown at 3|, and at the other end 32 to the casing. The connection to the member 26 is preferably a detachable connection so that members 26 carrying difierent sizes or widths of cutters may be used, the connection shown being that of a stud or pin 3| seating in a recess in the member 26. The casing 29 is slidable along the rod 21 but isheld against turning movements on this rod by means of a lateral extension 33 embracing an upright guide 34 also mounted on the base l0. Mounted on the base if! at the opposite side of the platform l l'is a similar guide rod 35, andboth of these rods have one or more guide slots 36 and 31 extending transversely therethrough and throughout the lengths of the rod forming a guide for the blade or flexible cutter 24, as shown in Fig. 2. The slots may be of different widths to correspond with different thicknesses of cutters or blades 24, the blades being closely guided by these guide slots, although having free movement therein, so that the blade is held straight and is prevented from moving out of its proper plane during the slicing operation, and thus permitting the cutting of thin clean slices. The free end of the cutter or blade 24 is connected to a knob or handle 38 at t-he outer side of the guide 35 which constitutes the means for operating the cutter during the slicing operation. Preferably the upper ends of the rods 21, 34 and '35 are connected by a horizontal rod 39 to help maintain them in the proper relation.
The operation is as follows:
The spring 30 is always tensioned and tends to rotate the member 26 so asto wind the flexible blade or cutter 24 thereon, the winding movement,=
tudinally across the material [2 to be out. At the same time-it unwinds this flexible blade from the member or nut 26, thus rotating this member, and as it is threaded on the threaded rod 21 this rotation will cause the member 26 and the casing 29 to move downwardly, as also indicated'in dotted lines, to at the same time carry the cutter or blade 24 downwardly through the material l2 in a direction laterally or at substantially right angles to its longitudinal movement and. in the plane of the blade. Rotation of the member 26 at the same time winds up or still further tensions the spring 30 as it is connected at its inner end to the member 26 and at its outer end to the casing 29, which is held against turning by the guide lug 33. Therefore, as thepull is against the spring the flexible blade is always held straight and taut. Also when pull on the handle "in the opposite direction to again wind or coil connection with the rod 27 will shift it and the i bladetogether with the casing upwardly to its norrnalor full line position in Fig. 1, ready to take another cut.
theflexible blade on it, and as this rotates the member 26 in the opposite direction its threaded The operator then by depressing the push rod 2| and the pawl I9 will feed the table II and the material I 2 forwardly the proper distance for the next cut. During the cutting operation the flexible knife or blade 24 is guided and kept straight by the guides 34 and 35 and by the pull against the spring .30, so as to prevent its buckling and to keep it in the proper plane during the cutting operation.
-.It -will be seen from the above that the thin, narrow, flexible blade during the cutting operation has combined longitudinal and downward sliding movement, and this prevents material sticking to it'and gives a clean smooth cut, even with soft material. The slight lateral curvature indicated-in Fig. 6 also helps to prevent sticking of the material to the blade as it'reduces the amount of surface actually in contact with the material being cut. It is of course, however, to be' understood the device is not limited to use for cutting such materials, but it is also very successful for cutting other materials such as meat, bread and the like.
