arson-marrow forming .part of Letters Patent No. 340,409; dated April 20,1886. Application filed January 25, 1886. Serial No. 189,863. (No modolJ To all whom it may concern.
Be it known that we, GEORGE W. ALBAUGH and WILLIAM H. GIBBS, both residents ofSout-h Bend, in the county of St. Joseph and State of Indiana, have, invented certain new and useful Improvementsin Milk and Cream Cans; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make. and use the same, reference being bad to the accompanying drawings, which form a part of this specification, and in which-- Figure 1 is a perspective viewof our im' proved milk-can. Fig.- 2 is a vertical sec-. t-ional view of the same. Fig. 3 is a similar .view taken at right angles to Fig. 2. Fig. '4 is a perspective view of the upper portion of the can, showing the cap removed. Fig. 5 is a horizontal sectional view on line as :0, Figs. 2 and 3; and Fig. 6 is a side view of a modification of the can,w-ith a portion of it broken away.
Similar letters of reference indicate corresponding parts in all thefigures.
Our invention has relation to that class of cans for transporting milk which areprovided with means for preventing the milk froin-chu rning within the can by the shaking of the same during transportation; and it consists in the improved construction and combination pf part? of the same, as hereinafter more fully desc ibed and claimed.
In the accompanying drawings, the letter A indicates the can, which is preferably cylin-' drical, although it may be of any other suitable shape, and which is' formed atits lower end with a downwardly-projecting flange, B,- which preferably contains a block, '0, of wood, 0 strengthening the bottom of the can-and preventing the metallic ring or flange at the bottom of the can from cutting or otherwise injuring the floor upon which the can maybe placed.
The can may be provided with flanges I) D at its upper and lower end, which retain the endsof fiat strips of wood E, which form a protecting-cover for the can, as shown in Fig.
6 of the drawings.
The lower end of the can is provided with a faucet, F, the cock G of which is provided with a flat handle, H, having a perforation, I,
.drawn off the caii.
may be securedby meansof a lock or other der side of the cover and of the bearing in near its upper edge, and a correspondinglyshaped cap, J, is securedto the end of a bracket, K, hinged to the body of the can, and fits over thehandle, having perforationsLLin its sides, which registerwith the perforation in the handle,,and-through which the bail of a padlock, M, may be inserted, securing the cock of the faucet, so that it cannot be turned until the padlock and the cap are removed.
A tube, N, extends from the upper end of the can down along the side of the same and opens into the lower end of the can, and this tube, which is provided at its upper end with a plug, 0, or other means for closing it, may be used for filling the can as well as for admitting air into the can when the contents are The stopper for this tube means, which can only be opened by a person hav-ingthe means for opening the same, so as to prevent any'addition to the contentsof the can, if desired.
The upper end of the can is provided with 75. two cars, P P, and the cover Q, which fits; tightly in the top of the can, is provided with a cross-strip, R, having slots S 'in its ends which may fit *upon the cars. A cross-strip, T, is secured upon the .top of the cover at right angles to theslotted strip, and has its ends U U curved upward to forui handles for ,the purpose of removing'and otherwise hand portion of a screw-threaded rod or shaft, Y,"
turns, and the upper end of this threaded shaft, is formed witha polygonal nut, Z, upon whicha handle, A, or crank fits, which is retained-by nut,]3 fitting uponthe upperinost screw-threaded end, 0, of the shaft. The smooth portion of the screw-threaded shaft is confined in its bearing by a collar, D', .upon the shaft, which collar bears against the unthe same, preventing theshaft from slipping up through the cover. v
A' follower or piston, E, has its central screw-threaded portion, F, fitted and turning upon the screw threaded shaft, so that by turning the shaft by means of its crank the fol! lower may be drawn up or down in the can. This follower consists, besides, of the central screw-threaded port-ion of two flaring rimmed disks, G G, secured to the screwthreaded portion, and having a ring, H, or annular packing clamped between their edges, nutted bolts passing through the disks and serving to adjust them uponthe ring or packing. By means of the bolts 1" the disks G 'Gf can be drawn toward each other, so as to force the ring H outward by reason of the flaring edges, and thus make a perfectly tight fit between the piston and the sides of the can. The friction of this ring against the sides of the can prevents the follower from turning with the shaft Y as it is being revolved to raise or lower the piston.
Abolt, J, passes through the perforated ears of the can above the slotted ends of the crossstrip and retains the cover upon the can, and one end of this bolt is formed with an eye, K, which may be brought to register with a perforationor notch, L in the slotted end of the strip, so that the bail of a padlock, M, may be inserted through the saideye and perforation, securing the cover upon the can.
A top, N, fits over the upper end of the can and over the cover with the crank, and the top of this top or lid is provided with an upwardly-projecting cylindrical flange, 0, upon which a cup, P, may fit, the said cup being of a known capacity,: and being, preferably graduated, so as to serve as a measure for the contents of the can when they are drawn off the can.
It will thus be seen that the can may be.
filled with milk, either through thetube or through the top, after having removed the cover and follower, whereupon the cover and theupper end of the filling-tube may belocked, so that it is impossible to add to. the contents of the can, whereupon the follower may be screwed down totbearagainst the surface of the contents, thus preventing them from moving and waving within the can, which in the case of milk or cream may cause it to churn and produce butter. The faucet may be locked also, and thus it is impossible to tamper with the contents of the can, either by drawing from the can or by fillingmore into the can.
When the can is used for delivery of smaller quantities than contained in the can, the faucet is unlocked, when any quantity may be drawn ofi from the can, and the follower may be screwed down after each time that any of the contents are drawn ofi, forcing it to bear against the surface of the contents.
.The packing-ring may be adjusted to bear more or less tightly against the sides of the can, bybeither tightening of loosening the nutted 'bolts of the disks clamping the ring, and the follower may thus be caused to slide with less or more case within the can, and to make the perfect. a a.
. Having thus described our invention, we
claim and desire to secure by Letters Patent.
of the United States- 1. The combination of acan having a perforated cover, a perforated cross-piece secured thereon having its ends curved upward and a rod passing through said perforations and having a follower at it's lower end, as shown and described.
2..In a milk-can, the combination of a can having ears at its sides and a cover, a crosspiece secured to said ears, and a top having a cut-away portion fitting the top of said can and said ears, as shown and described.
3. In a milk-can, the combination of a can having upwardly-projecting perforated cars, a cover having a cross-strip having slotted ends fitting over the said ears, a bolt passing through-the ears above the strip, a follower fitting within the can and having a central female threaded bearing, and a screw having the said bearing fitting upon it and having its upper end turning in the bearing of the cover, and having acollar below the bearing and a crank for turning it above the bearing, as and for the purpose shown and set forth.
4. In a milk-can, the combination of a can having a tube extending from its lower end to its top, a follower fitting in the can, and a screw fitting and turning in a threaded bearing in the follower and having means for revolving it, said tube opening into said can below said follower, as-and for the purpose shown and set forth.
5. In a milk-can, the combination of a can having perforated ears, a cover having slotted ears fitting'upon the ears of the can and having a notch in one of the slots, a boltpassing through the ears of the can above the cover and having an eye at one end registering with the notch in the slot, and a padlock having its bail inserted through the said eye and through the notch of the slot, as and. for the'purpose shown and set forth.
