ROTARY GRID-HOLDING MACHINE.'
Application ined July 1,
To all 'whom t may concer/n:
Be it known that I, JOHN M. AHLGREN, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana,`have invented certain new and useful Improvements in Rotary Grid- Molding Machines, of which the following is a specification. f
This invention relates to rotary grid molding machines and the prime feature of the invention is the provision of a pair of drums having co-operating molding dies formed in the peripheral faces thereof into which is poured molten metal for molding grids.
A further feature of the invention is the provision of means in connection with the drums for melting and introducing the metal into the molds while in a molten state.
A further feature of the invention is the provision of means for controlling the flow of the molten metal on its passage from the melting pot to the molds. y
A further feature of the invention is the provision Oimeans for driving said drums in unison,
And a further feature of the invention is the provision of means for introducing a .cooling mediuniinto the drums.
Other objects and advantages will be hereinafter more fully set forth and pointed out ing device and in the accompanying specification.
In the accompanying drawings.
Figure 2 is an edge elevation of the moldparts for operating the same, and
Figure 3 is a top plan view of the, device with parts broken away.
Referring to the drawings in vwhich similar reference numerals designate corresponding parts throughout the several views, 1 indicates frame members which may be constructed in any suitable manner and having bearings 2 and 3 into which enter the hubs 4: and 5 of hollow drums 6 and 7, the drum 7 being mounted in a plane above the drum 6, and having its periph-` c eral face in contact with the peripheral face of the drum 6.
Formed in the peripheral faces of the i drums 6 and 7 are seriesof companion grid 1922. Serial No. 572,195.
when the drums are rotated and molten` metal is introduced into the molds at one side of the drums, successive grids being formed so long as the drums are rotated and molten metal introduced into the molds.
The drums 6 and 7 are driven in unison through the medium ofgears 10 and 11 which intermesh with each other and which are secured to the hubs of the drums and at one end thereof, power being applied to the gears through the medium of a pinion 12, whichis mounted upon a shaft 13 and intermeshes with the gear 11, the shaft- 13 having a worm gea-r '14 attached thereto, which is driven from any suitable source of power through the medium of a worm 15. By providing a worm and gear drive for the drums, said drums will be givena constant steady drive, and consequently' the comp'anion molds' will always register with cachl other so as to form a perfect grid.
In order to convey molten metal to the molds and feed the same thereto in a con`r stant stream and without undue wastage of the metal, a melting pot 16 is positioned at one side of the drums 6 and 7 into which the metal to be melted is placed and below the melting pot is positioned a burner 17 ,f
for heating the metal and reducing the same to a molten state. Communicating with the lower portion ofthe melting pot 16 is a discharge spout 18 4through which thei molten metal is conveyed from the interior tom ofthe reservoir so that the metal discharging from the spout,v 18 will enter the reservoir between the baffle plate and the wall of the reservoir nea-rest the discharge spout.
On the opposite side of the baiiie plate 21 E is a vertically extending discharge port 22, the flange 23 forming the walls of port 22 extending a distance above the floor of the normal How, co-incident to the speed of ro y tation of thedrums. l
Communicating with the lower end of the port 22 is a nozzle 24, the opening through which is of a Width equal to the-Width of the grid molds 8 and 9, and the free end of the nozzle is so constructed and positioned that the metal flowing therefrom will be discharged directly into the molds at their point of registration with each other, consequently no appreciable quantity of the metal can escape from the molds. A burner 25 is also positioned below the reservoir 20 so as to maintain the metal at proper ten'iperature while flowing from the melting pot to the molds. l
In order to maintain the temperature of the drums at a substantiallyv normalfdegre, the hubs 4: and 5 are formed hollow 'and streams of water are conveyed int-o the drums 6 and 7 through pipes 26 and 27 respectively, while the hubs at the opposite ends of the drums are likewise connected with pipes 28 and 29 through which the water escapes from the interior of the drums thereby maintaining a const'ant flow of water through the.
drums which will thoroughly cool the same and maintain an even temperature. The water flowing through the drums also tends togcliill the-metal as it strikes the molds thereby causing it to quickly harden and rendering the grids in condition to Ybe handled 'as soon as they pass lfrom between the rolls.
Asthe grids leave the molds they are integral with each other and form a continnous strip, consequently it is necessary to sever the'grids, one from the other, which may be done in any suitable manner.
Having thus full described my said infvention, what I claim 'as n eW and desire to secure by Letters Patent, is:
1. A molding machine comprising companion rotating molds, and means for dis- ;kliargin'g molten metal horizontally into said fmolds substantially as set forth.
y 2. In 'a rotary molding machine, the com- ;'bination with a pair of 'drums having companion molds in the peripheral faces thereof, and means for .rotating'said drums in unison, of means for discharging a vconstant; 'flow of molten ymetal horizontally into said molds, substantially as set forth.
3. In a rotary grid molding machine, the Y combination with a pair -of drums having .co-operating moldsin the peripheries therematiere of, and'v means for rotating said drums in unison, of me'ans for reducing metal to a molten state, means for conveying the molten metal to said molds, and means for causing the metal to flow horizontally to the molds at a speed in unison with the rotation of said drums, substantially 'as set forth.
4. In a rotary grid molding machine, a pair of drums, one above the other and contacting therewith, continuous mold sections in the peripheries of said drums and arranged for co-operation with each other, means for rotating said drums, and means for maintaining the drums in cooled condition', substantially as set forth.
5. In a rotary grid molding machine, the combination with a pair of rotating companion grid molds, of means for discharging a constant flow of molten metal horizontally linto said molds, means for regulating the flow of the metal, and means for maintaining the met'al at a uniform temperature, substantially as set forth.
6. In a molding machine, the combination with a pair of drumsl having co-operating molds in the peripheries thereof, means for rotating said drums in unison, a melting pot for reducing metal to a molten state, a reservoir intermediate the melting pot and the point of discharge of the Vmetal into the in the reservoir, substantially as set forth.'
8. In a molding machine, a source of molten metal, 'a plurality of molds, a supply' 'line for continuously supplying'metal from the said source to the molds successively including a reservoir, an outlet leading from the reservoir to the molds, a nozzle discharging in the reservoir, 'a baffle in the reservoir between said nozzle and said outlet said baffle having its ends spaced from the sides of the reservoir, and means for heating the metal in the reservoir, substantially as set forth.
y In witness whereof, I have hereunto set my hand and seal at Indianapolis, Indiana,
' this 8rd day of February, A. D., nineteen 'hundred and twenty-two. Y,
