BUTTER-PRINTING MACHINE.

Specification of Letters Patent.

Patented March 31, 1908.

Application filed Novemberl, 1907. Serial No. 402,673.

To all whom if may concern:

Be it known that I, JnREMIAi-I R. PROUTY, a citizen of the United States, residing at Reedsburg', in the county of Sauk and State of Visconsin, have invented new and useful Improvements in Butter-Printing Machines, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

This invention relates to improvements .in machines for printing butter, and particularly to a machine for this purpose in which the operation of printing or bricking is accomplished by forcingthe butter through a frame and thereby dividing it into bricks or prints of the required form.

The principal object of my invention is to provide a butter printing machine which is capable of operating upon Igreen butter, that is, freshly churned butter, not yet solidied by compressing and cooling. The practice heretofore has been to place the butter in a suitable cooler and permit it to remain there until partly hardened, after which it is compressed, then divided into prints, and then returned to the cooler for further hardening. By the use of my invention I am enabled to take the freshly churned butter, compress the same, and then form it into bricks, all prior to the cooling, the necessity for rehandling being thereby done away with.

Another object of my invention is the `provision, inl the same machine, of means for first compressing and afterward bricking the butter, without the necessity of accomplishing these two operations in separate machines.

A still further object of my invention is the provision of means whereby the contents of the individual bricks may be accurately gaged, and all the moisture and texture in the butter retained.

In carrying out my invention I provide a receptacle in which the butter is placed and in which the same is first compressed by suitable means provided for that purpose. This receptacle is provided with a bottom, preferably removable, consisting of a `cutter frame through which the butter is forced after being compressed,`by means of. which that part of the mass of butter which has passed therethrough is divided into portions having the required length and width of `to view some of the interior construction;

Fig. 2 is an elevational side view of the machine, Fig. 3 is an elevational front view of the same; Fig. 4 is a vertical sectional view of the machine, the section being taken on the line. lr-l of Figs. 3 and 5, looking in the direction indicated by the arrows; Fig. 5 is a top plan view of the machine Fig. 6 is a cross sectionalview on the line 6-6 of Figs. 2 and 4; Fig. 7 is an enlarged detail elevational view of a ortion of the device; Fi 8 is a side elevational view of the portion s iown in Fig. 7 and Figs. 9 and 10 are enlarged detail views of parts of the machine.

In the several gures of the drawings, like reference numerals indicate the same parts throughout.

The machine is supported by a frame comprising four upright legs 16; upper and lower side rails 17 and 18 on each side an upper and. alower rear rail 19 and 20, and a lower front rail 21. Supported by the upper side rails 17 is a cutting-frame 22, this cuttingframe being suspended fromthe rails 17 by a bar 23 at each corner, these bars having hooked lower ends in which the frame rests. The rods 23 have their upper ends threaded and are provided with suitable nuts, by the rotation of which these bars are raised and lowered to afford adjustment in leveling the frame., The cutting frame 22 is provided with a suitable number of bars 25, 25 extending thereacross land having their upper sides wedge-shaped for a purpose hereinafter set forthl Extending at right angles withthe bars are smaller bars 26, preferably formed of small round rods. By means of the bars 25 and 26 the area within the frame is divided into sections having the form which it is desired to give to the butter prints.

Resting upon the frame 22. is the receptacle consisting of a box 27 of which the cutting-.frame 22 forms the bottom, and-in this box fits a vertically movable plunger 28. This `plunger is designed to rest upon the mass of butter within the box, means beinO provided whereby the plunger may be force down to either compress the butter or force the same through the cutting frame as desired. In operating the machine with i vertically movable toward and away from said frame, is a bed member 29 upon which rests a withdrawable slide or tray consisting of a board 30 provided with suitable handles 31. This bed rests upon curved cam plates 32 and 33 pivoted at'theirends tothe lower side bars 18 of the frame, and connected with each other below the Abed of the machineby a link rod 34 to causethem to move in unison. An operatinghandle-lever 35 is pivoted to the frame at 36 and is secured at 37 to the forward cam 32,fwhereby when thislever is raised to an upright position, as shown in Fig. 1, the bed will be elevated into engagement with the underside of the cutting-frame. When this lever isdropped to the position shown in dotted lines in Fig. 4 the bed descends, carrying with it the draw tray 30. Means are provided wherebythis movement may,.when desired, be made to occur simultaneously with a downward movement of the plunger so that the butter will be forced through the cutting-frame and will be divided into blocks by the bars of the latter.

Resting u on the contents of the receptacle is the fol ow er or plunger 28 consisting of a board having suitable means, such as a screw-eye 38, for the attachment of a rope or the like. This rope may extend upward to and over a suitable pulley and carry upon its `opposite end a weight to counterbalance the plunger and thus facilitate handling of the same. This lunger has secured to its upper side a pairo structures, each of which consists of two U-shaped rods 39, 39 having legs of unequal length, the longer of vwhich is secured to the upper side of the plunger, a stiffening bar 4() connecting the highest parts of these rods, and a cross-piece 41 spanning the ends of the shorter legs of these U- shaped bars. Other stiifening bars 40ZL extend at right angles with the bars 40. Each of the cross pieces 41 is formed with an opening through which vertically extends a pullrod 42, these pull-rods being arranged to be simultaneously moved up or down in proper slide bearings provided in the upper and lower side rails 17 and 18. Means are provided whereby when these rods are moved downward in their bearings the plunger will be locked thereto and will be moved therewith, while upward movement of these rods is permitted to take place without corresponding movement of the plunger. This means consists of a suitable clutch mechan- `29 is elevated the ism, which may com rise a pair of cams 43 carried by bearing p ates 44 secured to the cross-piece Y41 and adapted to grip the pullrod 42 at opposite points when this pul -rod is moved downward. When the rod is moved upward the cams relax their hold and permit such movement to take place independently of the plun er. To assist 'the cams in gripping the rop a spring 45 is provided having its ends secured to the cams and tending to draw them toward each other and into contact with the pull-rod 42. i

The means for actuating the pullrods comprises a lever 46 upon each side of the frame, these levers being pivoted at their rearward ends to the rear legs. yThe lower end of each of the pull rods is pivoted to the corresponding lever 46 at 47. Extending across the machine below the bed, and supported in suitable bearings in the lower side rails 18, is a rock-shaft 48 having upon one of its ends a cam 49, secured to and turning with the shaft 48. The opposite end of this shaft is also provided with a cam 50 and with a handle 51, this last-named cam and the handle being conveniently made in one piece as shown in Figs. 1. and 2. Each of the cams 49 and 50 is connected, by means of a strap 52,' serving as a cam follower, with the free end of one 'of the side levers 46. When the handle 51 is raised the side levers are lraised to the position shown in Fig. 1, the pull-rods 42 ascend with these leversand the cams 43 release their grip upon the rods, permitting them to move upward without raisingl the plunger from the contents of the box. yWhen the handle is depressed the cams operate to grip the rods, therebyl lockingk the plunger thereto, the plunger being forced downward upon the contents ofthe box and thereby i either compressing the butter or forcing the same through the cutting-frame. By raising and lowering the handle 51 while the bed butter is compressed until the desired degree of solidity is acquired.

It will be observed that the manipulation of the handle 35 raises and lowers the bed of the machine independently of any other portion of the machine and that the manipulation of the handle A51 raises and lowers the pull-rods 42, the lowering of the pull-rods being accompanied by the lowering of the plunger. When the desired degree of solidity has been imparted to the butter by raising and lowering the handle 51, with the handle 35 and bed 29 in the raised position, as above described, the handle 51 will also be raised to the upright position. The plunger is now resting uponthe butter and the bed is in contactwith the under side of the cutting-frame, with the butter resting upon the draw board or tray carried by the i bed. lfV both handles be now depressed, the

plunger and bedlwill descend atthe same time and with the same rate of movement,

the butter being by this operation `forced through the frame and cutby the bars of the same into bricks of the required size.

Means are provided by the operation of which the butter below the frame may now be severed from the mass above the frame, such means conveniently consisting of a cutting-off slide comprising a U-shaped bar 53 extending around three sides of the machine and having its ends connected by a wire 54. This frame is supported in suitable slide bearings 55, and by means of slide rods 56 upon which the ends of the bar run. After the butter has been forced through the cutting-frame in the above described manner the cutting-off slide 53 will be withdrawn to carry the cutting wire across the machine from side to side. This operation severs the butter below the frame from the mass of butter abo ve the same, leaving the cut-off portions in the form of bricks or prints of the required size. l

A suitable stop is provided for limiting the downward movement of the handle 51, and thereby gaging the thickness of the print, this stop consisting of a vertically-adjustable bracket 57 secured to one of the front legs 16. When the handle 51 has been depressed into engagement with this stop and the cuttingolf slide 53 has been drawn to sever the bricks from the butter above the screen the handle 35 may be further depressed independently of the handle 51, whereby the bed, draw board or tray and prints carried thereby are lowered slightly to separate the prints from the mass of butter and permit the draw board and prints to be withdrawn from the machine. Suitable means are provided whereby the handles may be locked together when they are to be simultaneously depressed, such means comprising a stud 58, on the handle 51, which, when these handles are in alinement, occupies a hole or depressed portion in the handle 35, as indicated at 59. When the handle 51 has been depressed to the limit imposed by the gagestop 57, and it is desired to further depress the handle 35 to free the prints from the mass as explained above, the handle 35 will be sprung away from the handle 5l and thereby released therefrom.

A suitable stop 6() is provided upon the upper rail 17 with which the handle 51 engages when in its raised position. The method which l adopt for connecting the pivoted end `of the lever 46 to the frame is such as to permit this lever to have a sliding endwise movement, this being required because of the fact that the pull-rod 42 is forced to move in a right line in its slide bearings. This method of connecting these parts consists in enlarging the end of the ever, as shown at 61, slotting this enlarged portion, and disposing within the slot a roller 62 arranged to turn on a pivot 63.

with the prints, is drawn off the bed 29.

This shelf consists of a metallic frame 64 having side rods with bracket ends 65 ex-v tending at a right angle with the side rods and hooked into screw-eyes 66 or the like on the front of the frame of the machine. This construction provides a form of shelf which may be folded up against the machine when not in use so as to economize space.

The butter will usually, when put into the machine, be in a greenH condition, consequently lacking consistency. Such butter would not be properly supported by a frame consisting simply of wires or rods of small diameter when the bed and prints carried thereby are lowered to take them out of contact with the mass of butter in the machine. To overcome this difliculty the sides and ends of the frame 22 are made to extend inwardly from the inner surface of the box 27 to form a shoulder 67 extending therearound. To further assist in supporting the mass of butter while the prints are being taken from the machine I make the bars 25 of substantial Width. Giving to these bars 25 a considerable Width results also in the finished prints being spaced sufficiently apart on the draw board or tray to admit between them the lingers of a person and thus facilitates the removal of the prints from the board. The bars 25 have their upper sides beveled or made wedge-shaped to guide the butter into the spaces between the bars and prevent the lodgment of butter thereon which would result if the bars, were formed with flat upper surfaces.

The small rods may be made removable so that they may be spaced at desired dis tances apart whereby bricks containing any desired quantity of butter may be produced. Or, if preferred, frames variously divided may be kept on hand, a proper frame for making bricks o'f the required size being selected and placed in position in the machine.

By the use of the machine herein described, and shown in the drawings, the work of compressing and bricking butter may be carried out with facility and rapidity. When a draw board or tray with prints thereon has into the cooler and another board maybe inserted into the machine ready to receive the next succeeding layer of prints. These operations may be repeated until all of the butter in the receptacle has been passed through the cutting-frame, whereupon the plunger will be raised and the receptacle refilled.

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