SPECIFICATION forming part of Letters Patent No. 623,165, dated April 18, 1899.

Application filed January 27, 1898. Serial No. 668,213. (No model.)

To (all whom, itmay concern:

Be it known that I, JOHN CHARLES LAWSON, engineer, a subject of Her Majesty the Queen of Great Britain, residing at No. 34 Norton Folgate, London, England, have invented an Improved and Useful Machine for Forming, Stamping, Cutting, and Delivering Pats or Blocks of Butter or Oleaginous Matter, of which the following is a specification.

My invention relates to improvements in machines for cutting, forming, and delivering blocks or pats of butter or like oleaginous matter as a continuous process, and has for its object the stamping, equalizing, cutting, and delivery of several such pats or blocks with one double movement. I attain these objects by the mechanism illustrated by the accompanying twosheets of drawings, in

which- Figure l is a front sectional elevation of the machine, showing the stamps in pressing position. Fig. 2 is an end sectional elevation showing the relative positions of the parts when the aforesaid stamps are in pressing position; and Fig. 3 is a perspective view of one side of the lever-gear, locking, cutting, and delivery mechanism not drawn to scale.

Similar letters refer to like parts throughout the several views.

A containing vessel A is mounted within a frame 13 and is arranged to hold the butter or oleaginous material. A plunger 0 fits it accurately and is caused to press upon the mass therein contained by means of a screw D, nut E, and guide-rods a a. When the oleaginous material is placed in A in a loose or broken state, a certain degree of homogeneity is required, and to that end I providea closing-plate F, Fig. 2, working in slides c, and this may be pushed inward to cover the two, three, or more holes I) b b" in the containerA. A certain amount of pressure may then be applied to the plunger 0 by the screw D without any of the contained matter exuding from the holes b. When the pressure has produced the required homogeneity, the scale (Z may be moved so that one of its marks coincides with the index f on the nut E. Then each descending mark will indicate an exact amount of oleaginous material exuded with each rotation of the screw D. The closing-plate F is then withdrawn and held back in the position shown by Fig. 2 until the container A requires to be filled again. A stamp G, with recesses corresponding to the orifices b b b" in the containerA,is carried byslides H H, working in guides g g, so that it may be alternately pressed against the orifices b b b or lowered into a water-tank I. A slot hit in each of the slides H H admits the curved end of a cranked lever J, which is connected by a common axis to a second lever K. Fig. 3, Sheet 2-, best explains the movement of these levers and the details of their arrangement. A cross handle-bar L, attached to two sliding rods M M, carries upon each rod a bracket O, having two stops jj, which engage with the top of the lever K, and thus as Lis pressed inward or pulled outward the slides H H are lowered or raised, respectively, by the action of the lever J. Projecting arms P P operate slides Q Q, carrying bolts m m, which are shot into the slides H H when they are raised, and the stamp G is thus held tightly against the orifices b b b' while the oleaginous matter is being pressed into its recesses by the depression of the plunger 0. The distance of the stop j, Fig. 3, from the lever K upon the full Withdrawal of L allows of the bolt-m being unlocked from the slide H before it is caused to descend by the combined action of levers J and K. A cutting-wire R tightly stretched is attached to each of the brackets O and adjusted to pass closely under the orifices Z) Z) Z) in A, and in its extreme inward stroke tipping the inclined edge'of the closing-plate F, which is always damp from its proximity to the stamp G, which rises from the water- 'trough I each time that the handle-bar L is pulled out, and thus cleans said wire R. A beveled tipping plate S is pivoted to the bracket 0 and is unequally balanced, so as to fall over Too ' withdraw the bolts on m.

bytipping them upon a traveling sheet of paper or into receptacles of card or metal placed ready to receive them.

The method of operation is as follows: In the position of the various parts shown by the drawingsadepression of the plunger 0 by r0- tation of the screw D, indicated by the index f and scale (Z, causes a certain predetermined amountof oleaginous matter to be pressed into the mold or stamp G through the orifices b I) Z)", said stamp being then locked by the bolts m m. Then the handle-bar L is moved inward and the mold or stamp G, carried by the slides H H, descends into the water-tank I, the first part of said movement being to The tipping plate S is now horizontal, and is so held by the horn T and advances under the protruding blocks or pats which fall upon it when out off by the stretched wire R. The return or outward movement of L withdraws the tipping plate S, carrying the separated blocks or pats, which are discharged upon its tilting at the end of the stroke into or upon a suitable receptacle. The stamp or mold G is then again locked in position ready for a repetition of the foregoing action. The closing-plate F is only used when the container A is first filled.

\Vhen unstamped blocks are required, the stamp G may be dispensed with, and the tipping plate may carry paper or metal boxes or cases to receive them and deliver them as the handle-bar L is moved.

I am aware that prior to my invention machines have been made in which cutting-wires have been used to separate blocks or pats of oleaginous material when the latter has been forced out in a continuous mass from a container, and therefore I do not broadly claim such a device; but

That I do claim, and desire to secure by Letters Patent of the United States, is

1. The combination in a machine for forming, stamping, cutting and delivering pats of oleagiuous material of a container A with two or more orifices in its base, a plunger 0 operating in said container, a nut E having an index and scale, vertical guide-rods a, a connecting said plunger and nut, a screw D passing through said nut and adaptedon rotatlon to move the nut vertically, a stamp or mold box G carried by said slides, a plunger (3 adapted to force the material to be acted on against said mold-box and a container A, in which said plunger operates substantially as set forth.

3. The combination in a machine for forming, stamping, cutting and delivering pats of oleaginous material,- of a plunger C, mold-box G adapted to receive the material acted on by said plunger, brackets O, a handle-bar conmeeting said brackets, a system of levers and slides connecting said brackets to said mold-' box and adapted to operate the latter, tipping plates S carried by said brackets, and a cutting-Wire R, carried and operated by said brackets substantially as set forth.

et. The combination in a machine for forming, stamping, cutting and delivering pats of oleaginous material, of a cross handle-bar L, brackets 0, connected by said handle-bar, slides H, H, levers connecting said slides and brackets, a plunger 0, mold-box G adapted to receive the material acted on by said plunger, and operated by said slides, and lockingbolts on m connected to said handle-bar and adapted to lock said mold-box in position su bstantially as set forth.
