AUTQMA'EEG CLEANING AND APPLICATION OF LAMPBLACK TO METAL HOLDS.
Application filed June 15, 1922. Serial No. 56%,605.
To all whom it may concern.
Be it known that I, JOSEPH LoUIs DOSTAL, a citizen of the United States, residing at 8530 Dexter Boulevard, Detroit, in the 6 county of Wayne and State of Michigan,
have invented certain new and useful Improvements in the Automatic Cleaning and Application of Lampblack to Metal Molds,
of which the following is a specification.
(0 The object of this invention is to provide means for first automatically cleaning and cooling the outer surface of permanent metal molds when used for the continuous production of iron castings and then applying a coating of lamp black so that the surface of the metal molds is cleaned and the coating of lamp black renewed between each casting.
The novel feature is the means provided whereby the cleaning and cooling blast of air is automatically controlled and the smoky flame which provides the coating of lamp black is likewise automatically controlled. The noveltyalso resides in the application of this automatic cleaning and coating device to a series of molds rotating in a horizontal plane so that a stationary air cleaning and coating device successively cleans and coats a number of molds.
Figures I and 11 show a pair of molds in position for cleaning.
Figure HI hows the general arrangement of the molding machine to which the cleaning and coating device is applied.
Figure TV shows the cleaning and the smokin tubes in detail.
In Figures I and H the pipe conveying the cleaning and cooling air is shown at A and the pipe conveying the combustible gas which supports the smoky flame is shown at M. These two pipes are supported by bars E and Q, which in their turn are supported from the center of the rotating molding machine, it being understood that the pipes A and M remain stationary and the molds rotating past them.
B is the valve controllin the supply of cooling air and this valve is controlled by means of a bell crank lever C, see Figure I. This bell crank lever C contacts with the cam D which is carried on the mold J. The bell crank lever C is supported by a bracket projecting from the bar E. This bar E is supported from the stationary center portion of the rotating molding machine,
' M and is controlled by the valve N through a bell crank lever O which is similar to the es bell crank lever 0 shown in Figure I. This similar to the cam D which is carried on the mold L. The bell crank lever O is supported from the bar Q from the center of the molding machine, see Figure HI, and is therefore stationary. After the combustible gas passes the valve M the passage forks at R and is delivered through two slotted pi es S and T against the surface of the mo ds L and K, see Figure IV.
. A pilot jet not shown is kept burning so that the combustible gases are ignited the moment they escape from the slot in S and T. The reason for slotting the pipe and not perforatin it isto avoid trouble with dirt clogging tie perforations and also to provide a very liberal quantity of gas so that every portion of the mold is positively covered with lamp black during the short period the molds are passing the slotted pipes S and T. This slotted orifice gives a paint brush efiect, duplicating exactly the result obtained by a manual application of lamp black with a brush.
The pipes U and V indicate the air cooling device conveying air from the hollow guides W and X supporting the hollow molds I and K. The outer molds I and K are operated by a cam Y, this mechanism being the subject of a co-pending application by D. W. Candler, Ser. No. 504,988.
An advantage of the above described cooling and coating dcviceis that any loose partic es of dirt adhering to the surface of the mold are first of all removed and then a thick coating of lamp black is applied. The continuous movement of the molds past the stationary slotted pipes S and T assures a uniform distribution of the lamp black over the entire working surface of the molds.
What I claim is:
1. In a molding machine having a plurality of permanent metal molds arranged to be automatically opened and closed and a to be translate-din a closed circuit;a stationary perforated pipe delivering a coolin and cleaning fluid against the surface 0% the mold; a stationary pipe conveying combustible gas against the surface of the mold; valves controlling the supply of said cooling fluid and said combustible gas, said pipes being arranged to pass between said molds; a cam carried by each pairof molds operating the two valves in sequence whereby the surface of each mold is first cleaned and then covered With lamp black.
2. In a molding machine having a plurality of permanent metal molds arranged to be automatically opened and closed and to be translated in a closed circuit; a stationary perforated pipe delivering a cooling and cleaning fluid against the surface of the molds; a valve controlling the supply of said cooling fluid, said pipe being arranged to pass between said molds; a cam carried by each pair of molds operating the valve whereby the surface of each mold is cleaned and cooled.
3. In a molding machine having a plurality of permanent metal molds arranged to be automatically opened and closed and to be translated in a closed circuit, a perforated pipe delivering a cooling and cleaning fluid against the surface of. the mold, a perforated pipe dischargin a combustible gas against the surface of the mold and arranged so as to deposit lamp black upon said molds after the surface of the molds has been cooled and cleaned by the said cleaning fluid.
d. In a molding machine having a plurality of permanent metal molds arranged to be automatically opened and closed and to be translated in a closed circuit, a member containing a passage adapted to conduct a cleaning and coolin fluid, a plurality of nozzles located on said member and adapted to act as discharge outlets for said cooling and cleaning fluid from said passage against the surfaces of the metal molds, a second member containing a passage adapted to convey a carbon supplying fluid, a plurality of outlets from said passage adapted to discharge said carbon supplying fiuid against the surfaces of the metal molds so as to de posit carbon upon said molds after the surfaces of the molds have been cleaned and cooled by the said cleaning fluid.
