APPARATUS FOR REMOVING PAINT FROM CYLINDERS AND CONTAINERS.
Original application filed November 17, 1924, Serial No. 750,359. Divided and this application filed August 21, 1925.
This invention relates to an apparatus for cleaning substantially cylindrical articles, and more particularly for removin paint or the like from such articles as cylin rical con- 6 tainers for compressed gases, although, of course, it is not confined to use for this specific purpose but may be used for cleaning other articles of similar type or shape. This application is a division of our ap- 10 p licaglran Serial No. 750,359, filed November It is an object of the invention to provide a device which will clean these articles, especially to remove paint from their outer l5 surfaces, which will clean them much more rapidly and thoroughl than the methods now generally used an will, therefore, perform this operation at a much less cost.
It is also an object of the invention to so arrange the mechanism that the articles will pass through the cleaning solution under the action of gravity, which movement will also cause the surfaces of the adjacent cylinders to rub to ether to assist in the cleani operation so t at no mechanical feeding, ru hing or scraping device will be necessary, and therefore, the cost of operation will be reduced to a minimum.
With the fore oing and otherobjects in view, we have d evised the construction illustrated in the accompanying drawing forming a part of this specification, simliar 'eference characters being employed throughout the various figures to indicate corresponding elements. In this drawing,
Fig. 1 is a longitudinal section through one form of device for carrying out our improved process.
Fig.2 is a top plan view thereof with the 40 cover, however, removed, and
Fig. 3 is a transverse section substantially on line 3-3 of Fig. 1.
Heretofore it has been a very diflicult and expensive operation to remove paint from the outer surface of cylinders, such as the cylindrical metal containers used for transporting and storing compressed gases. Various methods were used, such as scraping off the paint with special knives, burning it off with torches, and in some moreelaborate mechanical methods attempts have been made to simplify the process by inverting the cylinders one or more at a time in baths Serial No. 51,588.
of heated alkali, but all of these methods were very slow and expensive, especially where a large number of cylinders were to be cleaned. With our improved apparatus the surfaces of the cylinders may be more thoroughly cleaned at a much less cost.
In carrylng out our process we provide a tank 10 of an suitable size depending upon the sizes of t e cylinders to be cleaned and the operation required which is adapted to hold a suitable solution 11, such as an alkali when the material to be removed from the cylinders is a coating of paint, and the cylinders indicated at 12 are passed through this solution at the proper speed to give into one end of the tank, preferably leadingv from a suitable platform 14 of the desired height. At the lower end of this runway is a longitudinally extending runway 15 below the surface of the solution, and an upwardly inclined runway 16 leads from the opposite end of this latter runway and out the opposite endof the tank. These various runways may be formed of any suitable construction, such as T-rails as shown, and the runway 13 is higher than the runway 16 so that as the cylinders 12 are rolled from the platform 14 onto the runway 13 the greater weight of the cylinders on this runway will cause them to roll down this runway into the solution, along the intermediate runway 15 in this solution and outwardly from the tank by rolling up the runway 16. It will be apparent that by continuously feeding cylinders to the top of the runway 13 there will be a continuous movement of the cylinders through the solution in the tank and out over the top of the runway 16. It will also be apparent-that the weight of the cylinders on the two inprojecting through t e solution regulated accordingly.
clined runways will maintain the adjacent c linders in contact and will cause a considerable pressure between them, so that the relative turning of the cylinders as they roll along the runways will cause their surfaces to rub together while under pressure, and will scrape off the paint or other coating which is softened by the alkaline solution. Furthermore, this coating will be more thoroughly and quickly removed because it is scraped off by this rubbing action as soon as it becomes suflicientlysoftened by the solution, allowing the solution to gain access to the harder coating underneath. In other words, the coating is removed as it is softened and the softening solution is not reuired to penetrate through a thick coating; %urthermore this movement of the cylinders causes a continuous agitation of the solution so that fresh solution is constantly brought into contact with the coatin to be softened and removed, which still urther facilitates the cleaning operation.
Means is provided whereby the speed at which the cylinders move throu h the solution may be controlled and varied at will. A convenient means of doing this is to hinge the opposite ends of the intermediate runway 15 to the lower ends of the inclined runways 13 and 16 as shown at 17 and 18 respectively, and to provide means whereby this intermediate runwa may be raised or lowered to vary the inc inations of the in-.
clined runways. For this purpose upright struts 19 may be provided on opfposite sides of the tank and the rails 20 o the intermediate runway mounted on rods 21 extending between uprights 22. These uprights may be secured to the struts 19 by suitable pins 23 passing through the uprights and into openings in the struts, of which there are a plurality at different heights. Thus by removing the pins either end of the runway may be raised or lowered and secured in the proper position by rein sertin the pins. In this manner the inclination 0 the runways 13 and 16 may be varied and the s eed at which the cylinders move Guide means is provi ed above the cy 1nders on the intermediate runwa to prevent their moving upwardly under t e action of the pressure on opposite sides thereof and also the buoyant effect of the solution. This may be similar T-rails 24 extending horizontally above the cylinders and mounted on transverse bars 25 carried by upright members 26 which are adjustable u and down on the uprights 22 and held in adjusted positions by suitable pins 27. By this arrangement these upper guides may be moved to the proper distance above the lower rails 20 to accommodate any given size of cylinder, and when adjlusted to any particular size of cylinder wil move with the lower rails when they are adjusted to vary the inclinations of the inclined runways. A cover 28 may also be provided above the upper guides to more thoroughly enclose the solution and the mechanism.
Means is also provided for heating the alkali or other solution provided, such as a steam coil 29, supplied from an suitable source of supply by a pipe 30, an this coil is provided with any suitable form of trap 31 for condensation. A tank 32 is provided at the outlet end of the runway 16 and contains water or other suitable solution to remove the alkali from the cylinders as they pass out of the tank 10 over the top of the runway 16. The water from this tank may be kept fresh from a suitable source of supply through a pipe 33 and the level maintained by the ,drain 34;.
It will be apparent from the foregoing description that the device is extremely simple in construction and requires no mechanically moving parts, so that the cost of operation is reduced to a minimum. Furthermore, that the weight of the cylinders maintains them in close contact while in the solution so that the rubbing effect caused by the rotation of the cylinders as they pass along the runways thoroughly removes the coating softened by the solution. Furthermore, the operation is continuous. The action is substantially automatic as-all that isnecessary is to roll the cylinders to the upper end of the inclined runway 13 from the platform, and the head or additional weight is suflicient to cause the movement of the cylinders into and through the tank and out the lower inclined runwa 16. It has been found in practice that t e scraping and rubbing of the cylinders together during this movement and the agitation of the solution also caused by this movement promotes in a most remarkable fashion the speed with which the cleanin may be effected. Whereas in the most e cient prior apparatus known to us the maximum capacity was sixty cylinders in ten hours in actual practice we can with our apparatus remove paint from eighty cylinders in four hours, but this capacity may be increased by increasing the size of the apparatus.
Having thus set forth the nature of our invention, what we claim is:
1. In a cleaning device for cylindrical articles, a tank for a cleaning solution, a downwardly inclined runway for the articles leading into said tank, an upwardly inclined runway for the articles leading out of the tank and of less height than the first runway so that the articles will run down the first runway under the action of gravity and force similar articles up the other runway, and means for varying the inclination of one of said runways to regulate the speed at which the articles pass through the tank.
2. In a cleaning device for cylindrical articles, a tank for a cleaning solution, a
downwardly inclined runway for the arti-' cles leading into said tank, an upwardly inclined runway leading from the tank and of less height than the first runway, an intermediate runway in the tank between the first runways and hinged thereto, and means for raising-and lowering the intermediate runway to vary the inclination of the first runways.
3. In a cleaning device forcylindrical articles will pass through the tank on said runways under the action of gravity, an intermediate runway between said inclined above the intermediate runway.
4. In a cleaning device for cylindrical articles, a tank for a cleaning solution, a downwardly inclined runway for the articles leading into the tank, an upwardly inclined runway leading out of the tank and of less height than the first runway, an intermediate runway between said inclined runways and connected thereto, a top guide for the articles above the intermediate runway, means for raising and lowering the intermediate runway to vary the inclination of the inclined runways, and means for raising and lowering the guide to vary its "distancefrom the intermediate runway.
In testimony whereof we aflix our signatures.
