COOPER STOVE.

Application fi1ed March 2 To aZZ whom it may concern:

lbe it known that .lf, EDWARD J. LAMY, a citizen of the United States, residing in Elizabeth, in the county of Union and State of New J rsey, have invented certain new and useful Improvements in Cooper Stoves, of which the following is a specification.

This invention relates to'the stage in the maiuifacture of barrels in which, after steaming, shaping andassembling the stares to form a barrel body, it must be heated in order to dry out the staves, particularly where the barrel is to be made tight. This heating is effected usually by means of an oil burner within the barrel; and sometin'ies it is desired that the interior of the barrel be singed or even charred.

Usually the barrel body, whose staves are held together by top and bottom hoops, is placed upon a covered pit, the latter containing oil and air supplypipes, and also containing a burner'or cresset which extends up through the cover of the pit; the barrel standing upon said cover and surrounding the cresset. From the burner there usually rises a cylinder which forms the body of the cooper stove, to confine the flames rising from t e burner, said body usually extending up to a point a little above the middle of the bilge of the barrel; and the barrel is dried by heat radiating from the stove body, and by hot gases which rise from the stove to vent freely out ofthe top of the barrel.

It is an object of the invention to reduce the fuel consumed and the time required for the drying, singeing or charring operation, thus enabling an increase in the output without increased expense for labor or overhead, or to enable a larger number of heating outfits to be arrangerL within given limits, or to enable a given output to be reached with a lower initial cost for plant and room.

In many cases the finished barrels eventually develop defects in the nature of warping, splitting, leaking, unevenness or irregularity of form, local weaknesses, etc., and an object of the invention is to reduce or eliminate these difficulties, and insure a more perfect product,

Usually the bilge of the barrel is the slow- 7 est part to dry, as the ordinary stove or cresset does not force the heat out,;but dries first the barrel portions of small diameter, viz, the top and bottom portions, these portions, however, being least important, as it '7, 1923. Serial No. 628,011.

is the portions which have the greater curvature that need drying'the most, viz, the bilge portions. It is an object of the invention to overcome this difficulty.

To attain these and other objects, one of the features of the invention is'the securing of more direct and ample action of the heated gases upon the bilge portion of the barrel, as compared with previous methods, whereby the top portion of the barrel, which is of relatively small diameter, was exposed to more heat than the bilge portion, which is of relatively great diameter; whereby the heating of the end and bilge portions was rendered very unequal, thus developing in course of time defects in the finished barrel, besides requiring the drying-out operation to be prolonged, in the effort to dry out the bilge portion adequately, this of course necessarily heating the end portion ex cessively.

According to this invention, there is suspended or placed above the stove body a bilge-heater, which is in the form of a broad inverted cone, constiti'iting a heat-spreader or battle, which conducts the rising heated gases outwardly to the bilge portion of the barrel. It also serves to reflect heat radiated from the stove body outwardly to the bilge. The body of the stove may be cut down sufficiently sothat the upper edge of the gassprcading cone may stand within the bilge portion of the barrel, preferably a trifle above the middle of the barrel, to cause the hot gases to diffuse themselves throughout the bilge, that is, upwardly from a'point about level with the top of the truncated stove body.

The lower end of the barrel receives heat radiated directly from the stove, and the heat from the gases is absorbed largely by the bilge portion of the barrel, thereby insuring the prompt drying out thereof, whereas heretofore the gases have risen right to the top of the barrel while fully heated, thus tending to overheat the end of the barrel and underheat the bilge.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a sectional central elevation to illustrate the heating of a barrel body by means of the present improvements, which are shown in connection with the well known Parson type of cooper stove and quipment.

Figure 2 is a sectional perspective view of vheel 16 and an oil valve wheel 17; the

lmrner extending up through an opening- 18 in the cover 19 of the pit. In carrying out the present invention, the body 20, of the stove, which rises from the burner, may be considerably truncated or reduced in height from the usual practice, so that the top of it stands substantially below the middle of the el, or in the neighborhood of the point .3. the lower endsscction or thebarrel merges intothe bilgesection thereof. This stove is central with respect to the barrel, which consists oi? staves 21 held together by top and bottom hoops 22 and rests n 3011 the pit cover 19. V

Above the stove is a novel bilge-drier in the form of an inverted conical shield or spreader 23, the diameter of which may be considerably more than hall as great 'as'the greatest diameter of the barrel bilge, so as to conduct the hot gases outwardly from the stove to impinge upon the staves at the bilge, and also as to choke the passage for the rising'gas and hence check its speed of ascent, so that it lingers in the bilge and therefore surrenders more of its heat to the bilge sections of the staves. Thus the bilge is well heated, and although the rising to the upper end of the barrel is somewhat reduced in temperature, still it is suilicient for heating this end of the barrel, since said end is ot less diameter ascompared with the bilge portion and therefore requires less heat, and since the upilow of the heated gases is re stricted b the CliOlilIW action of the b1l6 .3 s e heater or gas-spreader 28, and hence the gases ascend slowly, as compared with the former custon'i to vent the unobstructed gases freely at the open top of the barrel.

The spreader or bilge-heater 23 may be separated from the stove as shown, to permit escape or gases from the latter; audit desired, in some cases, the stove 20 may also have a small individual cover or baille 24:

of the construction heretofore employed on cooper stoves; this stove-cover 24 being of about the same diameter asthe stove body 20, and resting upon the top thereof, but somewhat separated therefrom, the gases emerging from the stove body at its top side edges. This baiile 2 1, it used, may be of very small diameter as compared with the bilge-heater 23 above.

The bilge-heater23may be conveniently supported by means of a central pendent rod or support 25, fixed at itslower end in a cap 2-6, which is riveted at 2'? to the inner apex oi the spreader said rod having at its upper end an eye 28, into which is hooked a chain 29, the latter running over one or more pulleys 30, and carrying at its other end a weight 31, to counterbalance the heavy bilgeheater n3, so that the latter may be easily raised, and may also be retained in its elevated position.

, In some cases there may be provided the novel feature of an additional choke for the hot gases, in the form of a cover for the top of the barrel, this cover being undersized, however so asto leave a constricted vent 33 at the top oi the barrel for the spent gases, suiiicient to insure 'ood operation of the burner, while prolonging the confinement of the hot gases. The cover is also effective in minimizing radiation of heat out of the top of the barrel, thus still further reducing the time required and the fuel consumed in the operation. Both cover 32 and bilge-heater 23 may be made of iron, and the cover may have at intervals hooks 34; or the like to support it upon the top edge of the barrel; these hooks being bolted at 35 upon the cover. The spreader stem or rod 25 plays loosely in a hole 36 in the cover. The eyepiece 28, which is secured to the top of the rod 25, supports the bilgeheater 23 upon the cover 32 as'the latter rests upon the top edge oi' the barrel, as at Figures 1 and hen the weight 31 is pulled down, the bilge-heater is'carried up against the cover, and upon further ascent carries the cover up with it to the Figure 8 position, clear of the barrel, topermit its removal and replacement by a fresh barrel.

By this method the time required for dry ing out the barrel is substantially reduced, and the prod substantially in'iproved. In some casesfrom two to four minutes per barrel can be saved, with corresponding economy of fuel, as compared with from seven to ten minutes required in previous operations. It is also observed that no appreciable time is lost in withdrawing the disks 23 and 32 from the dried-out barrel and placing them in the succeeding barrel.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
