To all whom it may concern:

Be it known that I, CARL H. CARLSON, a citizen of the United States, and a resident of Iron Mountain, in the county of Dickinson, State of Michigan, have invented certain new and useful Improvements in Butter and Lard Cutters, of which the tollowing is a specication.

My invention is an improvement in butter and lard cutters, and consists in certain novel constructions and combinations of parts hereinafter described and claimed.

The object of the invention is to provide a device of the characterspecitied, especially adapted to cut out and remove a shaped pat of butter or lard from a iirkin or other receptacle, and which is provided with means for ejecting the pat from the device without the necessity of touching it with the hands or with any other tool.

Referring to the drawings forming a part hereof: Figure 1 is a central longitudinal section of the improved cutter; Fig. 2 is a similar view of a portion of the handle at right angles to Fig. 1; Fig. 3 is a section on the line 3 3 of Fig. l looking in the direction of the arrow; Fig. 4 is a section on the line 4 4 of Fig. 2; Fig. 5 is a perspective view of a portion of the handle with .the parts separated; Fig. 6. is a side view of a portion of the handle; Fig. 7 is a diagrammatic side view showing the method of use; Fig. 8 is a similar View showing a portion of the material cut out and in the act of being removed; and Fig; 9 is a similar view with the portion ready to be removed.

The embodiment of the invention shown in the drawings consists of a frame comprising a yoke-shaped body 1 provided with oppositely arranged substantially parallel arms 2-3 and with a tubular extension projecting from the center of the body portion in the opposite direction from the arms. Near its upper end the extension 1s prot vided with oppositely arranged longitudinal slots 5, through which extend the ends of a linger piece 6, which is secured by its center to the stem 7 of a plunger 8, which is movable between the arms 3 of the yoke, the stem sliding in the tubular extension.

The end of the stem 7 is provided with an annular groove 9, which is engaged by inwardly extending lugs 10 on the arms 12 of a sleeve 11, and the finger piece 6 is arranged between t-he end of the stem and the body of the sleeve as showniin Figs. 1, 2 and 5;- A sleeve 13 encircles the extension at the slots 5, the sleeve being provided with slots 14 registering with the slots 5 and with lateral flanges 15 having registering openings 16 through which is passed a bolt 17 for clamping the sleeve on the extension.

The slots 14 are of lesser width than the slots 5, and each is provided at its lower end with a lateral extension 18 havingva 'lip 19 at the corner formed byv the junction oi the slot with the lateral. portion, and the said lateral extensions extend in opposite directions, so that by partially rotating the linger piece it may be locked in the lateral extension, the lips preventing its disengagement.

Above the slots 5 the extension is provided with a diaphragm 20 having a central opening which registers with openings through the sleeve 11 and the stem '7, and a rod 21 is slidable in the stem and through the openings. The rod is provided on its lower end with a cross plate 22 and on its upper end with a nut 23 threaded thereon, and between the nut and the diaphragm a spring 24 is arranged for normally retaining the plate against the plunger. K

The free end of the tubular extension 7 is provided with a handle 25, and the lower ends of the arms 3 are connected by a cross bar 26, upon each end of which is journaled a cutter. Each cutter consists of a substantially triangular plate 27 provided on one side edge with spaced bearings 28 in which the rod is loosely received.

In operation, the cutter is inserted in the rkin 29, containing the material 30 to be out, with the parts in the position shown in Figs. l and 7. As the arms enter the material the cutters take the osition shownvin Fig. 7, since in this position they offer the least resistance. When the cutter is inserted deep enough to remove a pat of the desired size, it is rotated by means of the handle 25.

lVhen the cutter is rotated, the cutters take' the position shown in Fig. 8, for the reason above stated, and in their movement revolving about an axis coinciding with the longitudinal center of the tubular extension, the pat is separated at its bottom by the cutters, and on its sides by the arms 8, which have sharp edges 31, as indicated in Fig. 3. The pat is now completely separated from the remaining material, as shown in Fig. 8, and

l portion is removed from the rkin, Vit being understood that during the above described opera-` tion the plunger 8V is locked in position by the engagement of the linger piece with the lateral extensions of the slots, while the s ring, beingunder compression, holds the p ate firmly, against the plunger. The cutter with `the pat in lace is held above the rece tacle in which 1t is to be placed, and the ger piece is disengaged from the lateral extensions of the slots, and moved upwardly into the position shown in Fig. 9. The plate as shown4 in Fig. 9 is curved and arranged with its convex face downward, and as soon as it is released from the pressure of the plate it resumes its curved condition, thus freeing the pat from the plunger and from itself, except at the central portion thereof.

As will be evident from an inspection of Figs. 1 and 7 to 9, inclusive, the arms 3 of the yoke l incline inwardly toward their free end, so that when the pat follows the plunger in its upward movement it enters the widest prart of the frame, and is easily disenggged om the arms, slipping out at either s1 e.

The diametrical division of the pat made by the rod 26 may be practically obliterated before removing the pat from the firkin by a downward pressure on the plunger, the arms 3 and cutters 27 also aiding, by compactil'ig the lpat, or the cut ma be disregarded, in w ich case the pat wi l be in two semicylindrical sections.

The improved cutters may be easily separated for cleaning or other purposes,by slipping out the linger pieceA through the slots and unscrewing the nut 23, the sleeve 13 being first loosened and removed. The plate and rod may now be withdrawn. This procedure is indicated in Fig. 5.

The depth of the insertion of the cutter may be regulated by means of the sleeve A13, which may be adjusted on the extension, and when secured in adjusted position by the set screw 17 the plunger, wil limit the downward movement of the cutter, and the plunger is locked in fixed position by the engagement of the linger piece with the sleeve.

The nut 23 is moved out of the end of the extension by the spring 24, and into such position that it may be gras ed to turn the rod and the cutter 22 a hal turn, thus entirely releasing the pat from the plunger.
