APPARATUS FOR COATING IVIOLDS- SPECIFICATION forming part of Letters Patent No. 784,873, dated March 14, 1905.
Application filed September 20, 1904. Serial No. 225,215.
T 0 all whom it may concern.-
Be it known that we, CHARLES MERRITTS and HENRY L. BARTLEBAUGH, citizens of the United States, residing at J ohnstown, in the county of Cambria and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Coating Molds; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
Our invention relates to apparatus for coating the molds of metal-casting machines with suitable liquid and preferably viscous substances, whereby a free delivery of the casts is obtained and with the further object of eliminating the wear of and protecting the molds from contact with the hot metal.
Our apparatus is particularly adapted for use with pig-iron-castin'gmachines, the molds of which are supported and moved on an endless carrier, and our invention is herein described and illustrated in the annexed drawings in connection with such a casting-machine.
Heretofore it has been customary to coat the molds of pig-casting machines with carbonaceous material by subjecting the same to the sooty flame or smoke resulting from the imperfect combustion of coal or tar; but this method has been found in practice to be awkward and expensive, as it required a large amount of labor and materials.
Referring now to the annexed drawings, which form part of this specification and in which like figures refer to like parts, Figure 1 is a vertical longitudinal sectional elevation of our apparatus and of a portion of a pigcasting machine, the molds of which are arranged to travel in the direction of the arrow. Fig. 2 is a sectional view of our form of the paddle or swab on the line y y of Fig. 3, and Fig. 3 is a side view of said paddle or swab.
Referring to the characters of reference on the drawings, 1 represents a series of molds in their inverted position, said molds being connected by links 2 and supported on wheels 3, which travel on a track 4 in the direction of the arrow to the ladle or reservoir, (not shown,) from which the molten metal is delivered to said molds when in their upright position. The molds then travel forward on the track 10, through a cooling-tank 5, and thence to the end of the track, (not shown,) wherethe pigs 11 are ejected from the molds into cars in a manner well known to those familiar with the operation of these casting-machines.
Our apparatus for coating the molds is arranged beneath the molds and consists of a tank or box 6, partly filled with tar or other suitable liquid, which tank supportsa rimless wheel 7, having spokes or arms 8, each provided with a paddle or brush 9, preferably formed of a block of yielding material, such as wood, secured to each arm Sand shaped so that it will move smoothly along the inside surface of the mold and distribute the coating substance evenly over said surface. It will be readily understood, however, that the paddle or brush 9 may also be formed of material other than wood, or it may be varied in construction or arrangement, and we wish to reserve the right to all such modifications. \Ve have found that sheet-iron or a combination of sheet-iron with some flexible material, such as rubber or leather, can be used for the application of the coating substance, the only objection being the hardness in the case of sheetiron or the rapid wear of the brushes if made of some flexible material. On the other hand, the wood being comparatively soft does not injure the molds. At the same time it is hard enough to wear slowly, and its use has been found satisfactory in practice. The wheel 7 is supported on a shaft 12, which revolves in bearings 13, supported on the sides of the tank 6, as shown.
Referring to Fig. 1, it will be noted that the arms 8 are arranged so that while one brush or paddle is coating the bottom and rear side of the mold the next brush or paddle is already in contact with the front side of the next mold; Therefore each mold is coated uniformly on the sides and bottom, and this has been found sufiicient, as these are the first portions of the mold struck by the stream of hot metal. The metal itself then causes the coal tar or other coating substance to flow and protect the ends of the mold.
The tank 6 contains the coating liquid 18 and is mounted on two small wheels 14 and two wheels 1 1, the latter being of larger diameter in order to keep the tank horizontal. These wheels travel on the inclined track 15. The tank is held on the track 15 and balanccd by means of the coun'terwmght 16, which is suspended over a pulley 17 and connected to the tank 6, asshown in Fig. 1. This arrangement is made to allow the tank 6, carrying the wheel 7, to move along in the same direction as the molds travel, so that if there should be any obstruction in the molds said obstruction could not prevent the revolution of the wheel, as the tank 6 would then move along, thereby lowering said wheel until the arms of same would be released from the molds. The tank would then be drawn back by the counterweight 16 and held in its normal position by the contact of the paddles with the molds, as may be readily understood. This -movement would in no way interfere with the liquid or viscous substance in the tank, as the tank is so arranged as to always retain its horizontal position.
()ur apparatus is designed and arranged to :uitoi'natically coat the interior of the molds, as heretofore described, the movement of the paddle-wheel 7 and its attached parts being accomplished by the contact of the paddles or brushes with the interior surfaces of said molds, which latter are traversed in the directions indicated by the arrows by any wellknown means. As the paddle-wheel revolves the paddles are successively immersed in the coating liquid contained in the tank, portions of which liquid are thus carried by the paddles to the interior surfaces of the molds, thereby coating the same.
While we have shown our invention as applied to one particular form of casting-machine, it will be readily understood that its use is not limited to the exact construction shown, but it can be operated in connection with any machine having traveling molds for the purposes stated herein.
Although we prefer to use tar or similar material for coating the molds, we wish it understood that any suitable viscous or liquid substances other than tar may be used with our apparatus-such as clay-wash, lime-wash, slurry, or any other substance which would adhere to the surfaces of the molds for the purposes herein described. Furthermore, we
we claim, and desire to secure by Letters Patcnt, is
