Patented July 19, 1910.

To all whom it may concern:

Be it known that I, \VILLIAM D. MOUNT, a citizen of the United States, residing at Saltville, in the county of Smyth and State of Virginia, have invented certain new and useful Improvements in Barrel-Heaters, of which the following is a full, clear, and exact description.

This invention relates to special heating appliances, and more particularly to a keg and barrel heater, and has for its object the provision of means for increasing the capacity of barrel making plants.

In the process of making barrels it is customary after the staves h ave been set up and while temporarily held by the assembling rings, to heat them while in position upon drum stoves and thereby give them their permanent set and my invention provides an apparatus by means of which this heating operation, as applied to successive barrels, can be a continuous one, the barrels being placed in position upon a traveling heater; and hence the different stages of heating and, if need be, of cooling can be conducted simultaneously.

In large factories, numbers of stoves are required necessitating considerable floor space or room, and the presence of a number of operatives to manipulate the assembled staves which have to be moved toward and from the stoves, which latter are frequently, especially if a large number be used, somewhat remote from the stave assembler.

My device is adapted for use in plants of any capacity and necessitates usually, in practice, but one or two operatives therefor; such operatives not being ordinarily obliged to move from their respective stations.

Various other novel features of my in vention will be hereinafter described, and particularly set forth in the annexed claims.

Referring to the drawings which form a part hereof, and in which like reference characters designate like parts throughout the several views: Figure 1 is an axial section through my barrel heater; Fig. 2 is a plan of the same, the chimney being shown in section, said section having been taken on the line II-II of Fig. 1. Fig. 3 is a section taken on the line IH TII of Fig. 1 in order to better illustrate the mechanism employed for rotating the carrier.

Upon a fixed base 1 is rotatably mounted a circular frame 2; ball bearings 3 being provided between the said frame and base in order to reduce friction and render the device readily manipulatable. The frame 2 carries a polygonal casing or box 1, the bottom of which is preferably grated as shown at 5. A cover 6 is provided, preferably having flanges 7 for engagement with the upper edge of the said box, said cover having therein a plurality of apertures 8 centrically disposed about the axis of the device.

In the embodiment of my invention herein set forth, the polygonal casing is hexagonal in form, and a plurality of flanged cylindrical shells or members 9 are disposed opposite the respective faces of the hexagonal casing; the flanges 10 of said shells contacting with said faces. In the interior of each of the shells is a partition 11 which I extends outwardly through the same from the face of the hexagonal structure through substantially three-quarters of the length of the cylindrical protuberances 9 each of these partitions being preferably in the hori zontal plane. Masses of fire clay or other refractory material are disposed in various portions of the structure above referred to; the closed end 12 of each of the shells containing a mass 13 of the said refractory material; partitions 11 not extending so far through the said shell as to contact with the said mass. In the bottom of the hexagonal casing is correspondingly disposed a mass of refractory material 14, such mass being centrally recessed as at 15 and provided with a plurality of semi circular channels or troughs 16 extending radially outward from recess 15. Channels 16 lead into and are substantially of the same cross sectional area as the channels 17 formed by the lower portion of the cylindrical casings aforesaid and their respective partitions. A further mass 18 of refractory material is positioned in the upper portion of the hexagonal casing, such mass being provided with a cylindrical recess 19 extending therethrough and leading into the recess 15 aforesaid. The said mass 18 serves to cover the respective channels 16; the line of joint-Lire between refractory masses 14 and 18 being substantially in the plane of partitions 11. Finally a plurality, in this instance six, of vents or flues 20 are provided in the mass 18 respectively opening into the upper passages 21 which are formed by the upper-portions of casings 9 and partitions 11 and connect passages 21 with apertures 8 in cover 6 aforesaid. It

will thus be seen that a plurality of tortuous fines are provided starting at the ports 8 and successively passing through the passages or conduits 20, 21, 17, 16, 15 and 19.

The cover 6 is centrally flanged as at 22, which flange is received into a recess in the bottom of a chimney 23. The upper surface of flange 22 is disposed almost in contact with the lower portion of a circularly formed angle-iron 24, which is secured in any proper manner to the interior of the metallic, cylindrical portion 25 of the said chimney. The interior of the chimney is coated with a layer 26 of refractory material providing an interior space 27 of substantially the same diameter as recess 19 aforesaid. The chimney may be provided with suitable stiffening and supporting means, such as a flanged ring 28; and is intended to be permanently and non-rotatably fixed in position. Surrounding the chimney in adjacency to the cover plate 6 is an annular air pipe 29, preferably several inches in diameter, the upward extension 30 from which is connected to a pressure producing device (not shown); valve 31 being provided in the said pipe to afford control of the blast. Above pipe 29 is a correspondingly disposed gasolene or other combustible supplying pipe 32, provided in this instance with six sets of downwardly directed pipe sections 33. A plurality of valves 34 are correspondingly disposed between said pipe sections, so that a proper amount of gasolene may be allowed to descend therethrough, and both the air and gasolene are respectively directed into a plurality of burners 35, in this instance six in number in correspondence with the number of apertures 8 provided therebelow. The mouth 36 of each of said burners is quite adjacent to the aperturecl plate or cover 6, so that the flame emitted by said burners may pass downwardly through the conduits 20 and laterally outward through conduits 21, around the ends of partitions 11, inwardly through conduits 17 and 16, and finally up the chimney, whenever the said burners come in alinement with any of the said ports or openings 8. It is obvious of course that any number of burners may be employed, or that the apertures 8 may be of any desired size or shape, so that if desired 'a substantially continuous flame may be played around through the interior of the carrying members 9. In practice, I find that the arrangement shown affords even more than sufficient heat for the purpose in question; and that a greater number of burners is unnecessary. When desired certainof the burners may be turned off, so that the barrels may be heated for a predetermined portion of their travel and then allowed to cool to any desired extent before being removed from the apparatus.

0001 air will obviously be drawn through the draft passages when the heated medium is not supplied, owing to the draft created by the chimney, due to the heat generated by the burners which are in use. Upon each of the shells 9, I provide suitable supports 37 which are adapted to engage the upper portion of the interior of a barrel or of the staves assembled in the manner aforesaid.

For convenience in removing the stave carriers or shells, in order to clean the same when necessary, or for other purposes, I provide means for permitting the ready removal of the same; and the means for attaching the carriers to the respective faces of the hexagonal box or body, is hence, preferably, simply a plurality of hooks 38 which extend up from the upper portions of said box and engage the correspondingly disposed apertures 39 in the upper portion of the respective flanges 10 of said carriers.

Upon the exterior of the frame 2 are provided a plurality of oppositely disposed lugs 41-42. Brackets 4343 are carried by the upper portion of the base 1, and have slidably mounted therein in suitable guide-ways, a bar 44, said bar being held in position upon the said brackets by bracket caps 45. Bar 44 carries a pivotally mounted pawl 46, the notched end 47 of which is adapted for engagement with lugs 41. Pawl 46 is spring pressed, the spring being shown at 48 suitably secured to an upwardly projecting lug 49 upon the bar 44.

Pivoted at 50 upon bracket 43 is a locking lever 51, said lever being provided with a somewhat irregularly shaped cam-slot as shown at 52, in which travels a downwardly projecting pin 53 carried by the bar 44. As shown in Fig. 3, bar 44 is substantially at one end of its stroke, pin 53 being at the left hand end of slot 52. If now the said bar be moved to the right, the pin will proceed through the short straight portion 54 of slot 52, and will thence proceed through the longer and angularly disposed portion of the slot, thereby causing the lever to rotate inwardly toward the frame 2. In the interim, the pawl 46, by rotating frame 2, has advanced the lug 42 which happens to be in adjacency to a corresponding lug' 55, carried by lever 51, so that the said lugs cannot engage; lug 42 having proceeded beyond lug 155 before the latter has gotten into engaging position. It is evident, however, that the succeeding lug 42 will ultimately be engaged by lug 55; which will therefore limit the rotary movement, which the carrying apparatus is capable of, for any given single actuation thereof. This prevents the apparatus from rotating around continuously or too freely, which is obviously otherwise apt to occur, as all of the rotary parts are mounted on ball bearings as above described. When the bar 44 returns to the position shown in Fig. 3, lug 55 will be disengaged with its corresponding lug42, and pawl end l7 will engage with the next succeeding lug 41. Bar 4L4 is reciprocated by means of a link 56 which is pivotally secured thereto at 57, and the other end of which is pivotally connected at 58 to the hand-lever 59. This lever is of any suitable description, being pivoted to a suitable support at 60 which may also carry the usual guard or guide 61.

My device is admirably adapted for the purpose in question, being capable of heat ing barrel parts or staves to any desired degree and being operable by hand by a single workman without undue effort. The assembled staves are advanced around upon the carrier step by step, so that for example the man whose duty is to remove the staves therefrom, may be positioned at a point 62 adjacent the lever 59, and thus not distant from the operator who is stationed at 63 for the purpose of placing the assembled staves upon the machine. As both of the operators are hence conveniently positioned with respect to lever 59, either one may actuate the device, as needed. It will thus be seen that the assembled staves may be dried through an interval of time which is substantially equal to that necessary to assemble the staves of six barrels; and this I find in practice fully suiiices to satisfactorily dry out the staves, giving them their proper set.

I may point out in conclusion, that the movement-limiting device serves also to aline the burners with apertures 8 when the carrier is not being rotated.
