llclaims.

This invention relates to a cutting deviceand a method of assembling the same and has special reference to a device for cutting cheese, butter,

and the like, into slices of predetermined thicknesses. y Y

More particularly, this inventionhas reference to a cutting device and a method of assembling the same, the cutting devicecomprising a frame having a cutting member disposedr thereacioss and a guide roller mounted to rotate therein. 'I'he frame is preferably stamped or otherwise formed from a single sheet -of metal.

The present invention contemplates. lthe provision of a cutting member in the'form of a wire held under tension between ears formed preferably integrally with a 'frame member and a guide roller mounted to rotate on bearing members likewise formed preferably integrally with thev frame member. The frame member is formed of a single sheet of material having a handle portion and a U-shaped extending portion between the .arms of which latter the guide roller and cutting member are disposed, the frame being suitably strengthened and given an attractive finished appearance in the provision of a marginal beading therearound. The guide roller and cut- 'ting member are disposed between the arms of the frame while the positioning members therefor are in an initial position, whereafter the posi- 30 tioning members are moved to a changed position to secure the roller and cutting member in place.

Y A device of the above character built in accordance with the teachings of this invention may be manufactured at an extremely low cost and the resultant construction is very simple and durable. I'he operation of the-device is conducted with a'maximum of eiiiciency, the roller being guided readily along the surface of the material to be cut and the cuttingmember being held in a fixed relation therewith to sever a piece of a predetermined thickness.

One of the objects of this inventionisjto provide a device of ythe 'character noted above which is extremely inexpensive to manufacture, is sim- 45 ple in design and operation, is eiilcient in operation and is durable. f v

Another object of this invention isto provide a device of the type indicated above in which the frame is formed of a single piece of reenforced sheet metal. s s j A further object of thijs invention is to provide a device as recited hereinbefore in which the securing members for the guide roller and cutting member are formed integrally with the frame member.

Other objects andy advantages will hereinafter be more fully pointed out and Vfor amorefcomplete understanding of the characteristic features of this invention `reference may now be had to'` the following description when taken together 5 with the accompanying drawing, in Whichlatter:

Referring now more particularly'to the drawing,

Vthe device of this invention comprises a frame I0 having a cutting member I I and 'a guide roller I2 supported thereby. The frame I0 is preferably stamped or otherwise formed from a single sheet of metal and comprises a handle portion I 3 and a U -shaped portion extending therefrom and preferably integrally formed therewith, the U-shaped member having a' body' portion I 4 withl arms 'Il and I6 extended therefrom.

yThe arms I 5 and I6 are spaced tofreceive therebetween the cutting member II and thev guide 40 roller i2. Theframe,- including the U-shaped portion and the handle portion, is rigid and in orderto give a suitablestrength to the comparatively light weight sheetY metal employed and also in order to furnish an attractive finished appearance, a marginal beading I1 is provided on the outside of the frame.y Of course it is to beunderstood that this reenforcing portion may be disposed lintermediate the edges ofY the .frame memberor on the inside of the frame member asdesired, it being shown in the drawing merely for purposes of illustration that a desirable construction may be had by providing the bead around the outside marginal portion of the frame. n

In order to secure the cutting member II in a spectively.

fixed position relatively to the frame, the ends of the cutting member preferably in the form of a wire are tied over or otherwise secured to ears I8 and I8 preferably serrated and deformed from an intermediate portion of the materials of the respective arms I5 and Il. The ears I8 and I8 extend in the instance shown in the drawing substantially at right angles t the surfaces of the arms in an initial condition. However, this initial degree of angularity is not important in that the ears-may be set at various degrees with respect to the surfaces of the arms or with respect to a plane vertical to the surfaces thereof, whereafter the angularity is changed by moving the ears in a direction away from each other to increase the tension on the cutting member to any desired degree.

In the assembly of the cutting member Il to the device, loops may nrst be formed at the ends of the wire or apertures, and such loops, hooks, or apertures may then be engaged with the ears when the latter are in an initial position. A suitable die may be employed to move the ears in a direction away from each other until a desired de gree of tension is had on the cutting member. Of course,it is to be understood that it is not necessary to have the ears at the same relative angles with respect to the arms since one may be fixed initially at the position to which it will ultimately be in use andthe tension be brought upon the cutting element in' the change of degree of angularity of but one of the ears. Thus, for example, the ear I8 may be bent initially into its dotted line position in Fig. 2 and the ear I8 be given its position as shown in full line in Fig. 2, whereafter merely the movement of the ear I8 to its dottedline position will provide a sufficient tension on' the cutting member. Should the cutting element become loosened to any degree after use in cutting, the user, in order to give the cutting member a desired tension, would merely have to strike` either or both of the ears a blow to provide a sufficient amount of tension thereon.

In order to definitely locate the cutting element, if a wire be used as such, portions 20 and 2I may be formed preferably integrally with the arms I5 and I8, respectively, the projecting portions extending upwardly out of the planes of the surfaces of the arms and being provided with notches with which the wire engages. The loops of the wires extend over the ears I8 and I8 and contact with shoulder portions which are preferably formed on the ears tolocate the loops, the wire passing from the ears over the projecting portions 28 and 2I in the notches thereof.

In order to secure the guide roller I2 in position with respect to the frame, bearing

portions

22 and 23 are provided on These

members

22 and 28 are preferably formed integrally with the arms I5 and I8, respectively, andV project downwardly and inwardly therefrom.

portions

24 and 25 are preferably of substantial width at the juncture thereof with their respective arm portions and converge to the inwardly extending portion of the bearings, thev inwardly extending

portions

26 and 21 being formed of annular lateral cross-section. The

portions

28 and 21 are preferably formed into their annular shape from a strip formed integrally with the downwardly extending

portions

24 and 25 and the arms I5 and I6, the strips being rounded into such annular form with a central opening for receiving studs 2l and 28, respectively.

'The downwardly projecting extending from the ends of the guide roller I2 axially thereof.

Referring now to Fig. 6 of the drawing. it will be noted that in place of the annular bearings receiving the

studs

28 and 29, respectively, extending from the ends of the guide roller, the latter may be provided with an aperture for re ceiving the bearing

portions

26 and 21.

The bearing

portions

26 and 21, as hereinabove stated, extend inwardly from depending portions of the arms I5 and I8, respectively, or, it may be said they extend in a direction toward each other. However, in order to permit the guide roller I2 to be assembled therein, since the frame member is of rigid construction, the bearing

portions

26 and 21 extend at an angle to the horizontal or at least one of the bearings may be yso disposed whereafter the bearing or bearings may be moved into a single plane coaxial with the

studs

28 and 28. In changing the angularity of the bearing

members

26 and 21, the distance therebetween is considerably shortened and, of course, such distance is predetermined in order to permit of a desired fit.

In the instance shown in Fig. 3 of the drawing, both bearing `

members

26 and 21 are disposed angularly relatively to the horizontal and the guide roller I2 together with its extending stud portions are just permitted to engage the apertures in the bearing portions and come to a stop against the upper ends thereof. The bearing portions are then forced upwardly into axial 'alignment with each other and with the axis of the guide roller preferably by the same die members and in the same operation as that of changing the angularity of the ears I8 and Il, the movement shortening the distance, of course, between the bearing portions and coming to rest with just sufficient play between the ends thereof and the ends of the guide roller to permit of a desired rotation of the latter. It is, of course, to be understood that it is only necessary to change the angularity of one of these bearing portions, although, it has been found to be desirable in order to conveniently employ one form of4 die member to have the angularities in both of the bearing portions. The bearing portions are suitably reenforced in the provision of beaded portions extending intermediate of the downwardly extending

portions

24 and 25 and continuing into the supporting arms as shown at 30 and 3|.

With reference to the embodiment shown in Fig. 6, the bearing members 26 are disposed angularly relatively to the horizontal and the guide roller I2 is moved into position such that the bearings are permitted to engage the apertures in the guide roller and come to a stop against the upper surfaces bounding the aperture. The bearing portions are then forced upwardly into axial alignment with each.l other in the same manner as aforesaid, the movement shortening the distance, of course, between the bearing portions and coming to rest Within the apertures with just sumcient play to permit of a desired rotation of the roller.

I have above described that the bearing members themselves may be angularly disposed relatively to the horizontal, although it may be desirable to angularly dispose the man body portion of the arm angularly relatively to the hori zontal, as shown more particularly in Fig. 'Z in full lines. The body portion of the arm or arms, depending upon whether both arms or just one thereof is disposed angularly, is then forced upwardly in the same manner as the bearings previously described to obtain an axial alignment of the bearings with each other and the axis of the guide roller. l

As a. result offthis invention, a construction is provided whichmayvbe manufactured at an ex-- tremely low cost, the construction being very simple and durable. The operation of the device is conducted with a maximum of eillciency and the method `of assembly permits of a relatively low cost. l

While but a single embodiment of this invention fis herein shown and described, it is to be understood 4that various modifications thereof may be apparent to those skilled in the art without' departing from the spirit and scope of this invention and, therefore, the same is only to be limited by the scope of the prior art and the appended claims.
