BUTTER WORK SPECIFICATION forming part of Letters Patent No. 502,428, dated August 1, 1893.

Application filed .T une 9, 1892.

To au whom t may concern:

Be it known that I, EDWARD S. BoYNToN, of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Machines for Forming Butter Cakes, of which the following is a specifi- This invention relates to machines for shaping and cutting from a mass of butter the small cakes or pats usually served at table, and it consists in the construction and novel arrangement of parts as hereinafter set forth.

In the accompanying drawings Figure 1 is a side elevation of amachine embodying my invention. Fig. 2 is a top or plan view thereof with certain parts in section and certain parts broken away to clearly show other parts. Fig. 3 is a longitudinal vertical section on an enlarged scale, of a portion of the apparatus. Fig. 4 is a transverse section through theline of Fig. 2, showing the cutter employed. Fig. 5 is an enlarged side view of a die or mold employed. Fig. 6 is an enlarged view of a die showing lateral air escapes.

Referring by letter to the drawings, in which similar letters indicate similar parts, A, designates the frame of the machine, comprising side and end rails provided with suitable legs; and A', designates a horizontally arranged butter receptacle here shown as cylindrical and removably supported on the frame A. This receptacle A', may consist of any suitable material, such as sheet metal, but I prefer it to have an interior coating or lining of tin, so that the butter contained therein will not be injured by metallic salts, or the like.

The receptacle A is open at its rear end, and at its rear end is provided with a band ct of heavy or strong metal. At its forward end the receptacle is provided with a reduced outlet a. The outlet spout a is here shown as attached to a metal ring or band u2, removably engaging the receptacle A. This outlet c. and its end wall a3 are lined with tin n.4.

As a means for removably supporting the receptacle A on the frame A, I have shown the ring ct as provided with lugs a5, which Serial No. 436,071. (No model.)

upper sides of the side rails of the frame, and the ring or band a2 is provided with lugs a7 which engage in notches 0,8 formed on the said side rails. s

The receptacle A is made removable from the parts ct, a because it is designed that a number of receptacles may be furnished suitably packed with butter, so that when the butter is removed, and formed in pats, from one receptacle, a full one can be substituted for the empty` one, which can be immediately cleaned. I will now describe the means for forcing the butter out of the end of the outlet and cutting the cakes or pats.

B designates a plunger movable Within the receptacle A', and having a plunger rod B provided with rack teeth b, With which engages a pinion b mounted on a vertical shaft h2 having a bearing at its lower end on a transverse bar on the frame A, and at its upper end having a bearing in a block bs erected on a plate b4 supported by posts extending upward from the frame A. A Worm wheel B2 on the shaft b2 engages normally with a worm b5 on a Worm shaft B3, having bearings bs on the frame A, and which is movable longitudinally for a purpose as hereinafter set forth.

C, designates a reciprocating bar, supported by means of a bracket c secured to oneof the side bars of the frame A and a stud c extending outward from said side bar through a slot c2 arranged longitudinally in the bar C. A bell-crank C is pivoted at its angle to the stud c. One arm of this bell-crank is provided with a handle c3 and the other arm thereof is pivotally connected to a block C2 adapted to slide in Ways c3* on the bar C, arranged at right angles to the slot c2 and intermediate of its ends. Obviously by turning the bell-crank C the block C2 will slide up and down in the Way csi and reciprocate the bar C. A link bar C3 is pivotally connected to one end of the bar C and at its other end is pivoted to a piece c4 adjustably connected to a dog carrying lever C4. The piece c4 surrounds the dog lever C4 and is adjustable up and down thereon. It can be held in its adj usted place by means of a set engage under hook-shaped keepers d5 on the screw as shown. This adjustment is provid- IOO ed to regulate the throw of the dog and therefore regulate vthe plunger stroke and the thickness of the butter cakes or pats. The dog carrying lever C"r near its upper end is provided with a hole through which the worm shaft B3 passes and a dog C5 pivoted to the upper end of this lever engages with a ratchet wheel C( affixed to the shaft B3.VV By this construction it will be seen that when the bar C is reciprocated its backward movement will cause the dog C5 to ride over the teeth of the wheel C6 in the usual manner and that during its forward movement the dog will engage with a tooth, rotate the Worm and the worm wheel and cause the plunger to move forwardY sufficiently to force a small section of butter out the forwardend of the receptaf cle ready to becut off.

1: As to return the plunger out of the receptacle when all the butter is forced out would be too slow bya reverse rotation of the worm4 y wheel, I provide other means therefor, as folbutter.

lows: The shaft B3 is movable longitudinally in its bearings. It is provided at its Iouter end with a hand wheel D, by the turning of which the worm b5 turning against the teethf of the worm Wheel, which is now stationary, will move the shaft until the worm is out of engagement Awith the worm wheel; then by rotating the shaft b2, by means of a vcrank handle D', on its upper end, the plunger will be quickly retracted.

I `will now describe the means for orna-v menting the top of the butter cake or pat `and severing it yfrom. the` main portion of the through and movable vertically in a slot in thev arm e. e madein it and it is also provided with a v:transverse opening into which a metal nut e2 may be placed so that its threaded opening Vmay register with the hole e in orderthat the screw bolt Emay engage therewith. I

"have foundthat if the ornamental end of the die be made Vconcave or has its periphery at allparts extended beyond its centraltportion, i it is dilhcult to make a good `impression in the butter because of the air cushion formed,

4. as shown in Fig. 6.

unless the die is constructed with air escapes,

In making the ornamenv ytal die, I prefer to so form it that depressed portions will gradually incline rearward and outward from the center as at e3. the air to escape from between the die and.

butter.

. I may provide means for ornament-ing the edge of the butter cake or pat; ashere shown, f 'thismeans consists of what I terml a;periph. eral.die,-made in-.the form of a ring orlloush-r ing E3, secured by means of a set screw inthe end of the outlet. Of course a peripheral die Y receptacle. Y the bar C an upwardlyextending arm or pinV f on the frame Fwill'engage-with-.a keeper The die has a longitudinal hole Thisiallows of any desired configuration may be employed, or one having-a plain `interior surface maybe used.

In Fig. 3 the die will be seen as extended slightly within the outlet a. This occurs at the end of the backward stroke ofthe bar C and imprints the'end of the butter before it Vis pushed forward to be cut olf.

F, designates a cutter movable across the mouth of the outlet a to sever a pat of butter, which may fall into a receptacle placed to receive it. This cutter is in the form of a wire and is connectedl at its ends to a frame F pivotally connected to the forward extension of theloar C. `The operation ofthe cutterris Y as follows: After a section of butter shall have been ornamented by the die and pushed forward bythe plunger, the bar C will begin its backward movement. This will bring the cutter: against the face f, of the-outlet and the con tinuedbackward movement of thebar will 'cause the frame F toi turn on its pivot and move the cutter across the outlet andvsever the butter, which will fall into a'pan or other Upon the reverse movement of f2, secured to the front'f, and cause the frame F and cutter F to return to a normal position as shown in Fig. 2.

When a receptacle A is filledwith vbutter and placed in the machine I place against the rear end of the butter a tin-ned metal disk d ,against.whichthe plunger will strike when forcing the butter forward. To prevent the plunger, in its outward movement, from drawing they disk d, or butter, with it-by air suction, I provide thefpluger with a hole CL through which air mayenter.

Having. described my invention,l what I claim is 1. The combination with the'V receptacle of the plunger, having the air hole, the disk forward of the plungercthecuttenthedie a re,

ciprocating bar having an arm on-which-the die. is adjustably mounted and -mechanism substantially suchl as described comprising a crank for .operating said movable-parts, in
