SPECIFICATION forming part of Letters Patent No. 783,819, dated February 28, 1905.

Application filed November 28, 1904. Serial No. 234,671.

To (all II/7111771, if 'n'z/rt l cone/27w].-

Be it known that 1, James M. CuAMnnns, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Barrel-Heaters, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a vertical longitudinal sectional View through a barrel-heater constructed in accordance with my invention. Fig. 2 is a cross-sectional view on the line 2 2 of Fig. 1, and Fig. 3 is a cross-sectional view on the line 3 3 of Fig. l.

This invention relates to barrel-heaters, and is 1 )articularly designed for heating and drying cashs or barrels preparatory to hoopii'ig and finishing the same.

One of the objects of the invention is to heat the barrel or cask externally and internally, so as to obviate the necessity and inconvenience of lifting the barrel by hand for placing it around the heater.

Another object of the invention is to pro vide means whereby a maximum heat cliiciency will be generated by a given amount of fuel, so that the products of combustion will have an opportunity to generate considerable heat before passing off through the chimney or into the outside atmosphere when it leaves the heater.

Another object of the invention is to pro vide means whereby a hanging fire-pot or grate may be suspended within the heater in such a manner that the draft will pass through the grate from the top and then be deflected upwardly byasuitable bai'lle, so that the products of combustion may act upon the surrounding casing which is to be heated.

Other objects and advantages, as well as the noveldetails of construction of this invention, will be specifically described hereinafter, it being understood that changes in form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages thereof.

.ln the preferred form of my invention as illustrated in the accompai'iyingdrawings I utilize a plurality of stamlards 1, which may consist of castings, channel-irons, or any other suitable construction and which support a drum or sheetiron casing 2. This casing rests on top of a ring 2) on the standards, and upon the upper edge of the drum is a cover t, secured to the ring 3 by the tie-rods 5. The cover 4: is provided with a central opening siu'rounded by a depemling circular flange 6, extending within the casing .2 and having an inwardly-projecting lug '7 at its lower edge, which is in a lower but a parallel plane to the plane of the cover i. it will be seen that the lug 7 projects inwardly at a right angle to the llange 6 and constitutes a rest to support the hanging li re-pot 8, which is liared dmvnwaudly from its upper end to a point at its opposite end 9, said lire-pot having a dependingcircular baffle 10 integral therewith, the purpose of which will be apparent as the construction of the ii'ivention is better lll'ldOlStOOtl. The lire-pot 8 constitutes a receiver for the fuel, and at its lower end 2) are inwardly-projecting lugs 1.1., divided by spaces 12, whereby the outwardly-projecting lugs 13 of the grate 1.4; may be caused to alternate with the lugs 11, and by slightly ro'tatingthe grate 14 the lugs 13 will be caused to register with those designated by the numeral ll, whereby the grate 14 will be hungor suspended from the lire-pot 8. The grate 14L is open at its top and is provided with a plurality of vertical, bars l5 and transverse bottom bars 16, so that the draft through the fuel will in no wise be retarded.

Suspended from the flange (3 is a sheet-iron inner casing 1'7, which entirelysurroimds the lire-pot, grate, and battle and projects below the lower edge of said baitl'le 10. This sheetiron inner casing 17 is provided at its lower edge with an inwardly1 )rojecting llange 18, the inner edge of which surrounds an opening normally closed by a cover 19, having a lug 20 at one edge thereof and a swn'igmg locking device 21 at the opposite edge, so that the lug 20 and the locking device 21 may be caused to engage the flange 1.8, so as to support the cover ii) on said flange.

The top 22 of the heater is bolted or otherwise secured to the cover i, and it is provided with a dependingflange 23, extending within the opening surrounded by the flange 6, the flange 23 being substantially parallel with the flange 6 and having outwardly projecting flange 24 resting on the upper lug 25 of the lire-pot 8, to which said flange 24c is bolted. It will be observed that the flange 23 is substantially the same diameter as the entranceopening of the fire-pot 8, so that the fuel will be conveniently guided into the fire-pot 8, constituting the fuel-receiver, and into the grate.

A swinging cover 26 is pivoted to the top 22 of the heater, whereby the opening 27 may be uncovered for the introduction of fuel or to regulate the drafts.

In the top 22 and surrounded by the flange 28 is a smoke-opening 29, which communicates with a space 30, formed by the outer walls of the fire-pot 8 and the wall of the casing 17 Between the outer casing 2 and the inner casing 17 are the vertical rods 31 of the elevating device, including the base or platform 32, supported by said rod, and on which the barrel or cask is placed. These rods are connected at their tops by the cross-bar 33, and

intermediate the ends of the cross-bar is a pulley 34.

From a suitable support 35 is a cord or cable 36, passing around the pulley 34, thence over a pulley 37, and on the end of this cord or cable 36 is a counterbalance-weight 38 of about the same weight as the cash or barrel to be heated.

In operation it is to be assumed that lire is in the grate 1 k and that the barrel has been placed upon the platform 32. l he draft will enter through the top of the lire-pot, as indicated by the arrows, and pass down through the grate 14 to the bottom of the inner casing 17, where it will be deflected by the cover 19 and the baffle 10 in an upward direction through the space 30 and between the baflie 10 and the inner casing 17 until it passes through the smoke-opening 29. Thus the entire inner casing 1'7 will be heated and will radiate heat into the space 39 formed between the inner and outer casings and in which the barrel will rest. The operator may cause the counterbalance-weight 38 to descend and in an obvious manner raise the barrel 40 until it surrounds the inner casing and is in turn surrounded by the outer casing. Thus it will be apparent that the outer and inner walls of the barrel will be efficiently heated preparatory to hooping and finishing.

One of the particular advantages resulting from the construction hereinabove described is that the downdraft will permit an even heat to radiate from the inner casing of the heater, so that a uniform drying out will take place from one end of the barrel to the other. Another advantage is that the exterior of the barrel will also be thoroughly dried. When it is desired to rake the grate, this can be readily accomplished by removing the cover 19, so that access to the grate 14 may be easily had. By suspending the grate as indicated in the drawings the grate may be easily removed, as well as the entire fire-pot may be taken out or assembled. The arrangement and construction of the grate is such that an easy combustion of the fuel is insured and the draft Will be in no wise retarded. Therefore the maximum efficiency for the device will be provided.

Having thus described my invention, What Iclaim, and desire to secure by Letters Patent, is

1. A barrel-heater comprising an inner and outer casing, a hanging grate in the inner casing, and a battle surrounding the grate and extending nearly to the bottom of the inner casing; substantially as described. I

4. A barrel-heater comprising a casing, a cover for the casing having a depending flange, a fire-pot suspended from said flange, a grate hanging in said fire-pot, a cylindrical baflle depending from the lire-pot and surrounding the grate, said balile terminating at a point above the bottom of said casing, and a removable cover for closing an opening in the bottom of said casing; substantially as described.
