Beit known that I, GEORGE H. PETERSON,

a citizen of the United States, residing in thel county of Nemaha, in the State of Nebraska,

have invented certain new and useful lm-V provelnents in Cutting Apparatus; and I dov hereby declare the following to be a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and use the same.

The present invention relatesto improvements in cutting apparatus, and more particularly to that class of cutters adapted for cutting circular cakes or blocks of cheese, butter, or thelike, regardless of size or weight, whereby the article operated upon may be divided into pounds or fractions thereof.

The object in view is the production of a cutting apparatus which shall be capable of cutting a predetermined quantity of the article operated uponand at the Sametime be capable of penetrating the wrapper inclosing the article, as the cloth at the base of a cake,

of cheese.

With this and other objects in view it consists of certain novel constructions, combinations, and arrangementsof parts, as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a perspective view of acutting apparatus embodying the features of my in vention. Fig. 2 represents an enlarged fragmentary view of the knife, in side elevation, and the surroundingparts in section. Fig. 3 represents an enlarged detail perspective view of the scale-bar and holder. Fig. 4 represents an enlarged detail view of the bearing formed in the supporting-arch for the rock-shaft; and Fig. 5 represents a similar view of the lower end of the central guidepost, illustrating the outward flare p of the lower end of its guiding-groove.

In carrying out my invention, as illustrated in the drawings, IY provide asuitable box or casing,as 1,within which is pivotally or otherwise suitably secured a preferably circular table, as 2, which is mounted upon any suitable casters or antifriction-be'arings, as 3, whereby said table is free to be rotated when desired.l The upper face of the table 2 is preferably provided with circular graduated plates, as 4 4, in any preferred number, corresponding in size to the usual sizes of the cheese or other articles to be cut. i

Arranged centrally of and secured to the top of casing 1 is preferably provided a vertical post, as 5, extending a suitable distance intothe said box or casing 1. A vertical groove, as 7, is formed longitudinally of pbst 5 and is provided with an outwardly-dared portion at its lower end, as at 8. Vertical posts, as 9 9, are arranged at or near one corner of casing 1, between which posts a knife 11 operates. The knife 11 is arranged so as to be capable of both a vertical and a horizontal reciprocation, and the inner edge of the knife is guided by slot 7 during the vertical reciprocation of the same,whi1e the outer edge is guided in both the vertical and horizontal movements by lneans of posts 9 9. To

more effectually guide said knife 11y in its vertical movement and to prevent any possibility of longitudinal action during such vertical movement,I provide antifriction-rollers, as 6 6, on opposite sides of one of the posts 9, one near the upper and one near the lower edge of the knife. A bend, as 6', is preferably formed in one of the posts 9, near its lower end, for permitting the lower roller 6 Vto pass said post at such point when the knife 11 is at the lowest point of its vertical movement and is moved longitudinally.

Centrally of the upper edge of knife 11 is provided an upwardly-extending arm, as 12, which arm may be secured at its lower end to said knife by any suitable means, as rivets or bolts, and at its upper end is pivotallyse cured between the two parallel members of a link, as 13. The two members of link 13-are pivoted at their opposite ends to a lever, las 14, which lever is composed of two parallel members, each member being pivoted to one of the members of link 13, and the opposite ends of the members comprising lever 14 eX- tend on either side of post 5 and are provided with registering polygonal apertures for receiving the polygonal portionof the inner end 16 of rock-shaft 16, as best seen in Fig. 4. The rock-shaft 16 finds bearings for its inner end in the bifurcated portion, as 17', of armv 17, the upper end of said arm` being secured in any desired or preferred mannerto the top of casing 1 and the arms of bifurcation 17 surroundin post 5. By this arran gem cnt tho ICO end 1G' of shaft 1G will be supported on the opgosiie side of post 5 to that of the knife 11, and the said shaft will extend at a right angle io the parallel members comprisinglever Ll. tends through the walls of casing 1 at a snitable point, provided with a bearing-plate 18, and said shaft 1G is provided with a right-angled lever, as 15), having a handle 2O at its outer end,whereby said shaft maybe rotated.

To raise knife 11, handle 2O is grasped and pulled upwardly, thereby rotating shaft 1G, raising the lower end of lever 14, and with it link 13 and knife 1l, the said knife passing between the two members comprising link 3, as well as between the two members comprising lever 1.1:. To lower the knife, the operation is reversed, the knife having its inner edge guided by slot 7 and its outer edge guided by posts 9 9 by means of rollers G, as hereinbefore mentioned. lVhen knife 11 is in its lowermost position, the upper inner corner, or, rather, the upper portion ofthe inneredge, is adapted to extend slightly above the lower end of post 5 and in engagement with the flared portion S of slot 7.

A suitable handle, as 21, is secured to the outer end of an arm 10, carried by the knife 11. Said knife, being pivoted to link 12S, is free to be reciprocated horizontally by means of said arm 10 and handle 2l, the lower roller (.3 passing the loop 6' of post il. Vhen it is desired to make a horizontal or draw cut, it is only necessary to grasp the handle 21 and move the knife back and forth. This horizontal reciproeation of knife 1l. will be advantageous for many purposes, but principally for cutting the cheese-cloth on the base of the cake of cheese operated upon. It will be obvious that the flared portion S of groove 7 is adapted to receive the inner edge of knife vl l at each horizontal stroke, whereby all danger of missing groove 7 in vertically oscillating the knife after the same has been moved horizontally is obviated.

A scale-bar, as provided with suitable graduations, is arranged outside the periphery of the cheese or the article to be cut and on the same horizontal plane as the upper face of the said article. This scale-bar is hinged, as at 213, to a bar, as 2i, which extends approximately at a right angle thereto and has its Vfree end extending through an aperture in a lug, as 25, carried by one of the posts il. A set-screw 2U is preferably thread ed into lug 25 at an angle to and having its inner end in contact with har 24, whereby the bar may be adjusted longitudinally for adjusting scale-bar to aeconunodatc the various sizes of articles to be operated upon. ln operation the table 2, with its cake of cheese, is swung about until the cut edge of the cheese registers with the end of said scalebar or with an)7 desired mark of graduation thereupon, and the knife may then he operated as described. vWhen not in use, the

scalemhar .C22 is Vfolded b f means of hinge 23 'lhe outer end of rock-shaft 1G ex-` to a vertical position, and bar 24: is moved longitudinally through lug 25 until the scalehar rests against post G, when said bar is locked by set-screw 2G. The parts heilig in this position and the knife 11 raised toits highest vertical position, a cake of cheese may be readily placed within casing 1. upon table 2 or removed therefrom.

The arrangement of knife 11 is particularly advantageous, as it provides means whereby a downward stroke of lever-handle 20 will produce a downward cutting stroke of the knife, whereby greater power may the more readily be applied to the said knife, andthe pivotal connections ot' said knife permit of horizontal reci procation of the same, which is considered an important advantage.

Although I have particularly described one specific embodiment of the present invention, yet I do not wish to be understood as limiting myself to the exact structure specified, but shall feel at liberty to deviate from the precise shape, size, and minor details of the parts within the spirit and scope of my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
