Specification forming part of Letters Patent No. 119,666, dated October 3, 1871; reissue No. 4,865, dated April El,
My invention consists of certain improve- I ments in preserving and other kettles, too
fully explained hereafter to need preliminary description, the said improvements having been 'designed with the view of facilitating the handling of the vessel While pouring out the contents of the same, of preventing the heating of the bail 'or handle, and, of insuring va circulation of air beneath the kettle, under the circumstances described hereafter, so as to prevent the undue heating ofthe bottonrof if stops being somewhat inclined, so that, when be retained in a position slightly beyond the perpendicular, as
In 'the accompanying drawing, Figure 1 is a sectional view of a preserving-kettle with my improvements; Fig. 2, a side view, partly in section, showing the kettle as it appears when being handled in pouring out the contents;
Fig. 3,-a' plan view'of part of the top of theI kettle; and Figs. 4, 5, and 6, views representing rnodilications of my invention.
A represents apreserving-kettle of the same general form as those in common use, and havin g at its upper edge, at opposite points, lugs a a, to which is attached a bail, B. Aflip, b,
serves as a handle by which the operator can tilt the vessel in the; manner shown in Fig. 2,
this lip being situated at or very near the upper edge of the vessel, for three reasons: first, it is there more free from the'eiiects of the heat, and can, consequently, be manipulated Without danger of vburning the fingers; second, the lip, when situated at thejupper edge of the vessel, does not interfere with the ready mold.
ing ofthe same, as will be readily understood by those familiar with the manufacture of vessels of this class; third, the vessels, when arranged` in quantities for transportation, have to be placed one within the other, so as to be packed in as small a compass as possible. It
is important, therefore,vthat the sides of the vessel should be free from projections which would intert'erewith this plan of packing, and it will be evident that the lip b, situated at the upper edge-of the vessel, presents no impediment to the adjustment of one vessel within lthe same purpose.
I nary bail connected to the vessel inthe usual manner, alfords facilities for tilting the vessel; but I prefer to restrict the movement of the bail in a manner and for a purpose vwhich I vvill now proceed to explain.
The ordinary bail of a preserving-vessel can be turned freely on the lugs from one side to the other, and is permitted to rest on the upper edge of the vessel, the consequence of which is that the bail becomes too hot to be manipulated Without the intervention oi' a cloth or other protection for the hand. This objection Iove'rcome by forming stops or shoulders we upon the lugs a for limiting the movement ethe'bail. 'The stops :t prevent the bail from being turned over onto the vessel in the direction oi' the lip b, the
the bail is elevated, it will shown bygdotted lines in Fig. 1, the excessive heating of the bail being thus prevented when the vessel is placed on the lire. The stops w prevent the bail, when depressed, from being brought into actual contact with the edge of the vessel, but retain it in a position slightly above the said edge, so that it can be readily seized b'y the hand and elevated..` The stops rc, independently of the utility in retaining the bail in an elevated position, in which it is mantained in a comparatively cool condition, perform the important duty of restricting the bail when' the vessel isA` being tilted, as shown in Fig. 2, during which operation the bail is main tainedat right angles, or thereabont, to the vessel, the best position for insuring the e'ectual tilting of the same when its contents have to be poured out.
It is not essential in carryin gout my invention that stops mac should be employed for retaining and limiting the movement of the bail, as various equivalent devices may be used for In Figs. l and 5, for instance, the bail passes through an elongated vertical slot, d, in each lug a, and is retained in a vertical, or nearly vertical, position by projections or stops e e at either side of the direction, as shown in e' i 4,865 p one of the projections may be elongated, as the vessel which is apt to take place when the shown by dotted lines in the latter ligure, so usualcontinuous rib is employed; the rib, more as to perform the same duty as the stop a: in over, being nearly continuous, is not so liable restricting the movement 4of the' bail in one dito be broken as are the usual isolated legs. reetion., l I claim as my invention- AnothermodicationisshowninFig.6,where 1.
