BUTTER-PAGKERL to automatically pack'the butter firmlyin the tub or otherreceptacle in which it is placed.

My invention consists in the construction, arrangement and combination of the various parts of the device whereby the objects contemplated are attained,--as hereinafter more illustrated in t in -which 1 Figure 1 shows aside-elevation of the complete device embodying my invention with a tub or receptacle inposition thereon. The dotted lines in said figure show the position of the arts when the packingweights are elevate Fig. 2 shows an enlarged, detail,

e accompanying drawings,

sectional view of the bars thatsupport-the packing weights andthe guidedevices for them, said view being taken on the line 2"-2 of Fig. 1, and-Fig. 3 shows afront eleva tion of the complete device embodyingmy invention.

Referring to the accompanying drawings, I have used the reference numeral 10 to indicate the frame of the device. Nearthe upper end of the frame is a rotatable shaft 11 aving a pulley 12 fixed thereto and anidler 13 adjacent to the pulley, said pulley being may be driven by applied power.- At the central portion of the shaft is a sprocket wheel 14.

There is a separate guide frame'foreach of the reciprocating weights.

Each of said frames comprises three parallel bars 15, 16 and 17, the bars 15 and 16 being pivoted totheframe 10and the bar 17 beingpivoted to the shaft 11. These bars areall-connected with each other by means of the frame member 18 which is ar ranged vertically. By this arran ement t is obvious that the free ends of the ars 15, 16

and 17 maybe moved up and down and will always stand in parallel positions. Rotatably mounted in'the outer ends of the bars 17 Specification of Letters Patent. Application filed October 21,1908

is ash'aft 19 having a sprocket wheel 20 fixed to its centralportionandconnected by the chain 21 with-a sprocket wheel 14. On the ends of the shaft 19 are the cranks 22, which cranks'are connectedby means of thclinks 23 with the bars 2 1 that su port the packing weights. These bars are s lidingly mounted in the freeends of the bars 15 and 16 as folows:

In Fig. 2 of the drawings, the reference nu-' meral25 is used to indicate the forked end of one of the bars15', and pivotally mounted therein is a-block26 having a central opening inwhiohthebar 24is slidingly mounted. By this arrangement it is obvious that when the bars 15 and 16' are raisedor lowered at their free ends, theirpivots and thus maintain the bars 241 in vertical positions. At the lower end of each of the bars 24 is a packerweight 27. From'the foregoing description it is obvi ous thatwhen'the shaft 11 is rotated, the packing weights will be reciprocated vertically.

the packing weights is at its lower limit of movement at a time, hence the packing weightsthemselves resting upon the butter in a tub will support the weight of all of the bars andthe' mechanism connected with the free ends thereof. Hence, the said packing weights will be automatically lowered as the butterinthe tub becomes packed down and thereby lowered, that'is to say, when a tub full of butter in loose condition is placed under the packing weights and the packing weights are alternately reciprocated, then as the butter becomes packed and the level lowered, the packing weights will follow the level of the butter within the tub without any attention whatever on the part of the operator.

In order that the tub full of butter may be turned around so that the packing weights do not strike at thesame places successively on thebutter in the tub,l have provided the following mechanism: Fixed to the shaft 11 isa pulley 28 and mounted in the lower portion of the frame 10 is 'a rotatable shaft 29 having a pulley- 30 thereon connected with thepulley 28 by the belt 31. Rotatably mounted in the frame 10 is a vertical shaft 32; This'verti'cal shaft is operatively connected with the shaft 29 beveled gear wheels 33 and" 34 fiXed'to said shafts and in mesh with each other; Fixed the blocks 26 will-move on The cranks 22- are 'fiXedon the shaft 1 19 in opposite directions, so that only one of by means of the to the upper end of the shaft 32 is a rotatable platform 35 designed to receive and support a tub or other receptacle filled with butter or the like. By this arrangement it is obvious that the same power that operates to strike the packing weights also causes the tub full of butter to be rotated so that the weights strike upon the surface of the butter at different places. 7 In order to remove a tub of butter already packed and replace it with another containing butter unpacked, it is necessary to elevate the packing weights. In order to accomplish this, I have provided the following 5 device: Pivoted to the frame is a bell crank lever 36 having its lower end provided with a treadle 37. Supported above the top I of the frame 10 is a pulley 38 and supported at the rear of the frame is a pulley 39. A rope or cable 40 is fixed at one end to the u per portion of the lever 36 and is then passed under the pulley 39, then over the elevated pulley 38 and then its other end portion is attached to the bars 17. By this arrangement it is obvious that when the treadle 37 is moved downwardly the packing weights will be elevated to-the position shown by dotted lines in Fig. 1. V In practical use, theoperator first laces a foot u on the treadle 37 and there y elevates t e packing Weights. He then places a tub full of butter on the platform whereupon the packing weights may be mounted in the frame, a bar pivoted at one end concentric to the shaft, a second shaft rotatablymounted in the other end of said bar, means for rotating them in unison, another bar pivoted to the frame below the 1 12 first and parallei with it, an upright member pivotally connected with the said bars and arranged vertically, a crank arm on the end of the second shaft, a link connected with it,

a bar connected with the link and slidingly '3 mounted in the lower one of the said bars, and a packing weightat the lower end of the latter bar, a lever, a rope connected therewith and also with the upper one of said bars, and pulleys for said rope, for the pur- 13 poses stated.

3. In a device of the class described, the combination of a supporting frame, a shaft rotatably mounted therein, two frames each comprising three parallel bars, the two lower 85 ones being pivoted to the supporting frame, and the upper one to the said shaft, an d an upright bar pivotally connected with all three of said bars, a shaft rotatably mounted in the free ends of the upper bars of said frames, a 90 crank arm in each end of the latter shaft, said arms being extended in opposite directions, a sprocket gearing device connecting said shafts, a link pivoted to each crank arm,

a sliding bar pivoted to each link, means for J slidingly supporting said bars in the outer ends of the lower two bars of said frames, and a packing weight 011 the lower end of each of said sliding bars.

Then the shaft 11 is rotated by power applied to the pulley and when this is done the Weights 27 are alternately reci rocated in a vertical plane. They descen as the butter becomes packed into the tub and 40 hence the device needs no attention whatthroughout the tub because the tub itse 1s continuously rotated during the I c aim as my invention:
