all whom it may concern:
Be it known that I, CHARLES MILLS, a citin of the United States, residing at Newton 'pper Falls, in the county of Middlesex and tate of Massachusetts, have invented a cerin new and useful Improvement in Moldg-Machines, of which the following is a ecification. My invention relates to molding machines id has for its object to provide a new and nproved machine of this description.
My invention is illustrated in the accomanying drawings, wherein,
Figure l is a side elevation of a machine nbodying my invention. Fig. 2 is an end evation of Fig. l.
Like letters refer to like parts throughout yveral figures.
In the drawings I have illustrated a simle construction embodying my invention. 1 this construction the stripping plate A, attern plate B and stool plate C are armged so that they may be all moved toether and the pattern plate is also arranged i that it may be moved relatively to the ripping and stool plates. As shown in the rawings, the stripping plate A and the stool late C are connected to the end plates, or ieces, D, in any convenient manner, as by eing bolted thereto and said end pieces are rranged to move up and down in suitable aide-ways in the frame D1 of the machine. he pattern plate B is supported upon the lcentric shaft B1 by means of the connectg pieces B2 which are provided at one end Tith eccentric straps B51, surrounding eccenic shaft B1; said connecting pieces aie conected at the other end to the pattern plate any desired manner, as, for example, pins 1. The shaft B1 is mounted in the end ieces D and is provided with an operating ver B5 so that it may be rotated to raise nd lower the pattern plate. 'Ihe shaft B1 asses through a slot or opening B1 in the rame D1 of the machine so that it is free to iove up and down when the end pieces D re moved; said end pieces are connected by he connecting rods D2 with the eccentric haft D3 mounted upon the frame D1, said onnecting rods being provided with the ecentric straps D* which surround said eccenric shaft D3. These connecting rods are eferably provided with turn buckles so hat their length may be adjusted. The haft D3 is provided with the operating le- Speeicaton of Letters Patent.

ver D5 so that it may be rotated in order to move the several plates back and forth. It is, of course, evident that other means than the eccentric shafts and associated parts may be used to secure the desired movement. The patterns BG of any desired form are connected to the pat-tern plate and passed through suitable openings in the stripping plate A. If, for example, the patterns are of such a form as to require small sand cores such, for example, as are required in the molding of nuts, or similar devices, there will be associated with each pattern a stool C1 which also projects through the pattern BG and pattern and stripping plates as illustrated. The machine may be mounted in any desired manner, depending of course upon the use to which it is put. If, for example, it is used for molding nuts, the machine may be mounted upon a bench, or the like.
The flask E is preferably provided with beveled sides, as shown, and can be laid or rested upon a movable device such as carriage E1, which runs on rails E2, passing beneath the patterns and stripping plate, or upon a flat smooth plate. This flask opens upwardly and the sand is loosely filled therein, being heaped up above the edges. The flask is then passed under the vertically adjustable scraper F which determines the depth or amount of sand required for mold of proper density, and then on to the proper position under the machine. The patterns are then forced down into the sand to the proper depth and the sand in t-he flask rammed or compressed to the proper density by the patterns, stripping plate and stools, the patterns during this movement projecting through the stripping plate. The combined plates with patterns and stools and scraper F may be adjusted to secure the desired density of the sand. This movement of the stool plate, pattern plate and stripping plate is brought about by rotating the eccentric shaft D3. The rotation of this shaft by means of the eccentric straps and connecting rods moves the end plates, or supporting pieces, D, downwardly and said end plates carry with them the stool plate, pattern plate and stripping plate, and stools and patterns mounted thereon. Then these plates have been moved downwardly the proper amount, toform the desired impression and compression, the patterns are drawn upwardly out of the sand through the stripping plate by rotating the eccentric shaft B1. The combined plates are then raised by means of the eccentric shaft D3 and the nished part of the mold is then moved from under the machine. Y Y
The stools C1 project downwardly through the pattern and stripping plates and the patterns, forming guides :tor the pattern plate during its vertical movement produced by rotating the eccentric shaft B1. The combined plates must always be given such a movement that at the extreme of the downward movement the under surface of the stripping plate has compressed the sand to the level of the upper edges of the flask. The sand is given the desired density by providing a sulicient throw for the plates and by properly adjusting the scraper F.
'This may be accomplished in any desired manner, as by using eccentrics of dierent eccentricity or throw, or by adjusting the turnbuckles associated with the connecting rods D2.
A cope may be formed in a manner similar to that f the nowel as heretofore described and by placing the cope and nowel together, the complete mold is formed. This construction does away with the necessity of turning the mold over which is a great advantage in cases where there are small green sand cores liable to break and fall oft' in the turning as, for example, in the molding of nuts and the like.
In the forming of sand molds the sand in the liask should be compressed to a certain density to secure the best results and when this density is ascertained or determined all of the molds should be formed with the same density. By means of my present device, the proper density of the sand may be easily ascertained and when once ascertained all of the molds may be made of this uniform density. In order to secure the proper densit it is necessary, as it were, to have two adjustable factors: First, the depth or amount of the sand in the iask must be made adjustable, and second, the throw of the stripping plate, or, perhaps more properly stated, the compression plate, for the stripping plate is a compression plate and is used for this purpose. The depth or the amountof the sand may be adjusted by adjusting the adj ustable scraper F and the throw ofthe compression plate may be adjusted in any desired manner as, for example, by the turn-buckles associated with the connecting rods of the eccentrics. It will be seen that, when once these parts are properly adjusted to secure the proper density of the sand, the tlasks may then be rapidly run through the machine and the sand in each iask will then have a uniform density and the best results may thus be secured without any attention whatever on the part of the operator. The compression plate must have such a throw that when in its loose position its lower face is substantially on a level with the upper edge of the flask and hence the sand in the flask will thus be compressed so that it will be level with the upper edge of the flask. For any given liask therefore after the stripping plate is properly adjusted it is only necessary to adjust the scraper to secure the desired density but the compression plate must be made adjustable so as to permit the use of flasks of various sizes.
I have described in detail a particular construction embodying my invention but it is of course evident that the parts may be varied in many particulars and the construction and arrangement altered to correspond with conditions presented and that some of the parts may be omitted and others used with parts herein shown, without departing from the spirit of my invention.
