BARREL HEATING, DRYING, AND CHARRING APPARATUS.

Application filed December 27, 1924. Serial No. 758,481.

This invention relates to new and useful improvements in heating, drying and char ring apparatus, and it is to be understood that this invention is notlimited to any particular art; but for the purpose of illustration, and by way of example only, is disclosed herein for heating, drying or charring barrels.

An important object of my invention is to provide a device of the class described embodying means for burning a flame within a sealed barrel in which the presence of air is negligible. For this purpose, what is known as a self sustaining fuel is used and which contains a sufficient quantity of oxygen to be burned within a vacuum.

Another important object of the invention resides in the provision of a heater which will cause heat to flow in a continuousor circuitous path within a closed receptacle.

A further essential feature of the invenl tion is to provide a device of the character specified includinga' heater which is automatically rendered operative upon proper positioning of an article in relation thereto, and which is rendered inoperative upon re moval of the object from proximity to the heater. i

Vith these and other objects notspecifi ically mentioned in view, the invention consists in certain constructions, combinations and parts which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying drawings forming a a part of the application, and wherein like numerals are employed to designate like parts throughout the several views:

. Figure 1 is avcrtical longitudinal section of one form of my heating apparatus."

Figure 2 is a transverse section of the same taken on line 2-2 of Figure 1.

Figure 3 is an enlarged fragmentary section of the upper right hand corner of the chamber illustrated in Figure 1.

Referring now more particularly to the drawings, it will be observed that I have disclosed an apparatus especially designed for the treatment of barrels. However, wherever the word barrel appears, it is to 'be understood that I do not restrict the invention to such class of articles; and that my invention comprehends the treatment of any article in the manner claimed.

hereinafter Referring more particularly to Figures 1 and 2, the numeral 7 designates a cylindrical oven having a closed top 8, which, as will hereinafter appear, serves as a closure for a barrel when the latter is properly positioned for treatment. The bottom 9 of the oven is open, as illustrated,for the passage into the oven of barrels to be treated.

A treating device or heater 10 of any desired type extends into the oven through the closed top or closure 8, and in the present instance consists of a pipe depending into the oven and terminating in a burner tip 10' of any suitable construction.

This heater includes an open ended cylindrical shield 6 suspended in spaced relation to the top or closure 8 by means of a pair of brackets 5 as illustrated, it being observed that the burner tip is disposed centrally within the upper end of the shield and spaced from the side walls thereof. When the burner is in operation, the flame therefrom is projected axially through the shield and creates a continuous or circuitous flow of heat within the oven.

The burner is provided with an elbow 11, from which extends ahorizontal pipe or conduit 12, which is arranged in proximity to the top of the oven as illustrated, and terminates in a valve casing 13, in which is disposed a normally closed valve, not shown,of any suitable type. Extending vertically from the valve casing 13 is a supply pipe 14, which furnishes self sustaining fuel to the burner, and tapped into this supply pipe is a pilot pipe 15 having a regulating valvelG for controlling the amount of fuel passing therefrom. The pilot pipe projects through the top of the oven whereby its dis charge end is arranged in proximity to the heater 10 to provide a pilot light. A fire check 17 is interposed in conduit 12 to pre vent combustion of the fuel within the supply pipe.

- The oven 7 is supported a substantial distance above the floor by means of legs 18 having their upper ends offset as illustrated, to be secured to the oven at spaced points circumferentially thereof.

Projecting from the top of the oven and from the lower end thereof, at diametrically opposite points, are pairs of vertical guides 19. It will be observed that the upper pair of guides are arranged in vertical alignment to those extending from the lower end of the support 22 upon elevation of the same.

oven whereby a pair of vertical rods 20 may posed upwardly offset extensions 21 of a vertically movable barrel support or closure 22 for the oven.g As shown in Figure 1, this support is equipped with a boss or raised portion 23 which is adapted to enter and close the open bottom of the barrel as well as'to center thebarrel upon the support. The upper ends of the rods 20 are connected by a bridging bar 24 disposed above the top of the-oven; Any suitable means may be provided for raising or lowering the barrel supp0rt 22, but in the present instance T haveillus-trated such means as consisting of a cable 2 5 connected by one end to the bar 2 1 and trained over a pair of pulleys 26 snitably mounted withits other end attached to a weight 27.

The means I provide for rendering the heater operative upon positioning of the barrel within the oven by means of the vertically movable support 22, consists of avertically movablepush" rod 28 slidably mounted in the armssupporting the guides 19' at one side of the oven. The upper end of this push rod 28 is equipped with an enlarged head 29 which normally rests upon the upper guide 19 and"'supports the rod,

so that the lower end of the push rod 28 is normally disposed slightly below the bottom of the oven for engagement with the barrel The valve within the Valve casing 18 is equipped wit-ha stem which depends from the casing'and is'disposed int hepath of movement of the push rod head 29 so thatwhen the barrel support 22 engages the lower end of thepush rod and movesit vertically, the head 29 will-raise the valvestem and valve to open the same and permit the fuel to How through "the pipe 12-into the burner or water 10.

' In operation, it will be understood that the heater is inoperative, and the pilot light adjacent the heater is continuously burning. The barrel support 22, being disposed below the oven and in the position illustrated in Figure 1, is in position to receive the barrel to be treated within the oven.

A headless barrel 31 is shown in the drawings, but it is to be understood that the apparatus described herein'is not limited to the treatment of headless barrels alone, since obviously the barrels to be treated may be equipped with bottonrheads; but it'isnecessary that the top heads be removed. When a headless barrelis to be subjected to treatment by the apparatus, it is placed upon the boss 23 of the barrel support 22 so that the boss enters and forms a closure for the bottom of the barrel which is retained in an upright position as illustrated. By pulling downwardly upon the weight 27 or cable lo which it is attached, the rods 20 are moved vertically togetl1er with the barrel support and barrel, until the latter is disposed wholly within the oven 7. As the barrel support approaches the lower open end of the oven, it engages the push rod 28, thereby clcvatin the same and opening the valve within casing 18 to permit fuel to flow to the burner or heater 10 where it becomes ignited by the pilot to create a flame or hot blast. The push rod 28 and valve have sullicient movement upwardly to permit the barrel support 22 to close tightly against the open bottom of the oven while the open top of the barrel engages the top or closure 8.

lVhen the parts assume this position, the oven and interior of the barrel arc substantially air-tight, and consequently, hcat from the burner will be confined and conserved. The flame from the burner 10, as stated previously, is projected longitudinally of the shield 6 and creates a circuitous flow of heat moving through the shield, out of the lower end of the same and thence upwardly thereofto again enter the open top of the shield. This flow constantly travels around and around in the same path, while the burner is in operation. This heat may be employed for cleaning barrels, i. e., removing rosin from the interior walls thereof, or for shrinking the stavcs, or for charring the interior walls of barrels for purposes well understood by those conversant with the art.

After the barrel has been subjected to the desiredtreatment the weight 27 is lifted, thereby permitting the barrel support 22 to descend by its own weight, and upon its initial downward movement, causes the head 29 of the push rod 28 to move downwardly and permit the valve within the casing 13 to close in order to cut off the supply of fuel to the burner. The barrel support will find rest upon the floor, at which time the treated barrel may be replaced by one lo undergo treatment in the oven.

It is to beunderstood that I do not restrict the invention to the use of the particular type of heater 1O disclosed herein, since obviously this heater may be an electric type or in fact any suitable type, although in the present illustration I have preferred to show a type of burner which is capable of burning self-sustaining fuel, as I have found this type to be advantageous, in view of the fact that with self-sustaining fuel I am able to cause a flame to burn within the oven wherein there is a lack of presence of oxygen, :1 fl'cr the burner has been in operation for a short interval of time. The invention also comprchends the support of a heater within the oven in any suitable manner, although it is Fill lllf) llll to be particularly understood that it is preferable to make provision in such a burner, whereby heat therefrom will be caused to travel in a circular path by means of a shield 6 such as disclosed, or any other arrangen'ient which will perform this function.

The self-sustaining gas which I have referred to throughout the application is a gas which contains in itself, only a sutlicient amount of oxygen to cause combustion of the gas Without the aid of oxygen from any other source.

Although I have described this invention for heating, drying or charring barrels, it is to be understood that I have called the heater 10 a treating device, since it will be obvious that instead of employing a heater 10, any other form of treating device may be substituted therefor, for subjecting the articles or barrels to treatments other than the heat treatment and accordingly it is to be understood that the appended claims are to be construed with such scope.

It is to be understood that various changes in the arrangement of the elements constituting the invention may be varied without departing from the scope of the appended claims.
