(01. 20-117) 1 2 This invention mates to food treating devices and more particularly to’ a vdevice for slicing and somewhat above the level of the correspond ing bar It. At the opposite side, a similar ‘rod 22 is provided, in a corresponding location with butter, cheese, or the like. > It is the principal object of the invention to provide a cutter for quickly and easily cutting or slicing butter,‘ cheese, or other material of similar characteristics into uniform and ‘neat slices or pats, the device being simple in con struction and such that it may be easily kept ‘in a clean and sanitary condition. - I It is a further object to provide such a butter slicer adapted for cutting 'a mass of butter simul taneously into a large number of slices or pats, and which may be readily adjusted to provide for ber cutting of slicesthe each mass of ainto desired a predetermined thickness and sub stantially uniform with all the other slices cut. Other objects and advantages will be apparent from the following description, the accompany ing drawing, and the appended claims. In the drawing- ‘ Fig. l is a plan view of a butter slicer con respect to the adjacent bar I5. Each end of the rod 22 however is supported in a block 23 which is laterally adjustable in a slideway 24 formed ‘in each ‘of the end flanges 12, its position being de termined by set screws 25 secured in lugs '26 formed on the ?anges 12. It will thus ‘be'clear 10 that upon tightening screws 25, the carrier block 23 moves laterally outwardly, and thus the rod ‘22 is moved in the direction vaway from rod'2 I. Means are provided to forma series of cutting knives, this means being in the form of a rela This wire is a single integral piece the opposite ends of which are suitably 15 tively thin wire 21. secured in place at opposite ends of the bars. ‘The wire is looped around the respective outside rods '2! and '22, and is then passeddownwardly and inwardly under the respective bars l6 and IS, in‘ a vseries ‘of passes, progressing in a regular manner from one end of the bars to the other. At each passage under the- bars l5 and It the structed in accordance with the presentinvention; wire 21’ is threaded through the coils of the Fig. '2 is a side elevational view of the same; and Fig. 3 is an end elevational view looking toward 25 springs l1 and 18 at regular intervals such for the righthand end of'Fi'g. 1. _ example as passing under every other cell of the springs. Thus in effect the cutting wire 21 is Referring to the drawing which discloses a pre threaded back and forth from one side of the ferred embodiment of the invention, the device frame to the other over the extent of the bars, comprises a frame member which is ‘preferably formed of two spaced side pieces H1, integrally 30 at each traverse being made to engage under the coil of the respective spring to thereby determine joined to end portions ‘l I, forming a continuous and fix its spacing at a regular and ‘predetermined closed frame member. ‘The end'portions 'l I over amount. Since the position of the Wire is fixed hang the remainder of the device and are con by its engagement at each traverse ‘with the lower veniently located for ‘grasping by the ‘operator. At the ends of the side'p'ieces l0 there are pro 35 side of bars 15 and Hi, it will be seen that-all the portions l9 which form the actual cutting knives vided downwardly extending flanges i2 ‘which may be integrally formed with the frame, and to the lower parts of which ‘there are secured respec are supported in a common horizontal plane. It will be clear that upon the tightening of screws 25, and the consequent lateral shifting of rod 22 A pair of bars l5, it of circular cross section 40 with respect to rod 3|, the wire will be tightened throughout its entire extent, and all the trans are supported in the end pieces is in suitably versely extending portions‘ is will assume a pre spaced relation inwardly of and ‘below the level determined tension suitable for the cutting op of side pieces Ill. The bars extend generally par eration and will thus constitute a set of approxi allel to each other and longitudinally of the frame, providing a ?rm and rugged construction 45 mately parallel, uniformly spaced, cutting wires or elements. , for the device. Spiral springs H and .18 are In order to provide for predetermining and received over the respective bars 15 and i6, each coil of the springs having a uniform spacing with varying the number and the ‘thickness of the slices which are cut, means are provided for con respect to the other coils, With such spacings‘re maini'n-g substantially uniform throughout the ex 50 trolling the expansion and contraction of- .the two springs, This means comprises one or a pair of tent of the expansion or contraction of the clamps 30, 3|, at one or both ends of the frame springs. ’ I asshown. These clamps are engageableover the At one side of each end flange 12, an open rods l5 and It at the ends thereof adjacent end notch 20' isformed within which there is received tively the two oppositely facing end pieces l3‘. the rod 21 which is thus located outwardly of 55 pieces 13‘ ‘and are slidable axially along the reds. 4 Their position may be ?xed by means of set’ parting from the scope of the invention which is screws 32 so that upon loosening the set screws, de?ned in the appended claims. _ the clamps may be brought closer toward or moved farther away from each other, to thereby effect a corresponding contraction or expansion of the two springs. This operation will result in a uniform deformation throughout the lengths of the springs, with the result that the individual What is claimed is: 1.
