NITgE STATES MACHINE. FOR MAKING MOLDS FOR CASTINGS.
SPECIFICATION forming part of Letters Patent No. 282,588, dated August 'i', 1883,
Application filed December 13, 1882. (No model.)
T 0 all whom it may concern Be it known that I, ELEAZER THOMAS, of Pawtucket, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Machines for Making Molds for Castings, of which the following is a specification, reference being had to the accompanying drawings, making a part thereof.
The object of this invention is to furnish a power-machinethat is, one adapted to be 0perated by power supplied from the drivingshaft in a foundry-by which to effect the 001m pacting of the sand around the pattern in a founders flask, as a substitute for the manual labor of rannning, the work of said machine greatly facilitating the molders labor and improving the character of the castings.
The special work which my machine is designed to accomplish is the slow, uniform, and powerful pressure ofthe sand from opposite directions toward the pattern in the center of the flask without tasking the workman s strength. The machine furnishes, in addition, a springsupported platform mounted on trucks, serving as'the molder s bench, and as a carriage to easily move the filled flask beneath the press ing-machine.
I11 the drawings, Figure l is a perspective view of the machine complete, ready for use, and showing the platform in position beneath Fig. 2 is a transverse section of the flask, showing the positions of the followboards in full and dotted lines; and Fig. 3 is a detail illustration of the slot-and-pin connection, which permits a vertical movement to the sprite-cutting tube.
A A represent the frame of the machine, strongly made of wood or iron uprights and cross-pieces, and solidly supported to resist the strains of use.
13 is a platform, arranged to be drawn forward on its truck-wheels G and track D to the position indicated by dotted lines in Fig. 1, to support the flask F while the molder is at ,work, and to be rolled backward with the filled flask upon it to its place beneath the plunger G, so that the follow-boards E of the flask, Fig. 2, may be pressed toward each other, as denoted by dotted lines, to compact the sand.
The tracks D D are supported on springs H, powerful enough to bear the weight of the forward and backward movement said platform may not drag upon the horizontal bars A beneath its ends, but may run freely over and slightly above them, thus greatly lessening the labor of handling the flasks.
Pressure upon the flask to pack the sand therein brings the ends of the platform down 011 the rails A, compressing the springs H and depressing the rails D temporarily. Catches I, engaging with pins J, hold the platform at the front of the frame until the flask is ready for pressure.
Vhen the flask containing the pattern has been filled with sand, instead of compacting it by ramming in the usual way, or by any leverpressure requiring manual labor, the necessary pressure is exerted by mechanical means, as shown in the drawings. A plunger, G, having two pistoirrods, K, works vertically through bearings L, fixed to the frame, and a very slow reciprocating movement is given to said rods and plunger by a pitman, M, extending from each rod to a crank or crank-wheel, N, 011 'a rotary or semi-rotary counter-shaft, O. A
train of gearing or of belts and pulleysserves to reduce the speed and enables the workman to observe the extent of compression exerted, and to suspend or relieve the same at the proper time in a manner well known without interruptingthe rotation of the main shaft. The counter-shaft 0 may, however, make a complete revolution, and the pitmen' M M a continuous and uninterrupted reciprocation by so adjusting the length of the pitmen as to give only the requisite pressure at the extremity of the stroke. Such adjustment maybe effected by means of a sleeve-nut serving to shorten or lengthen the pitman, or, as illustrated in the platform B and the loaded flask, so that in its drawings, clamps or collars I, adjustable by means of set-screws, may secure the ends of the pitmen to the piston-rods K at the proper points.
In Fig. 2 I have illustrated a sprue-cutting tube, S, which has a vertical movement through the upper follow-board, E, and through a teat, T, secured to the under side of said board. The stroke of the plunger carries the tube down, as indicated by dotted lines, but does not detach it from the follow-board and teat, to which it is connected by a slot, a, and pin. b. This movement cuts out of the mold as much sand as lies within the tube when it has been so carried downward and compacts such portion of the sand, so that it is removed with the tube inclosing' it when the follow-board is taken off, thus forming with the teat a complete sprue with reservoir.
Having thus described my improvements, I claim 1. I11 a power molding-machine, the frame A A and movable platform B, in combination with the follower G, having duplicate piston-rods K K, each provided with double bearings in the frame and with a pitman, substantially as and for the purposes herein set forth.
2. In a molding-machine, the frame A A and spring-supported track D D, in combination with the wheels and platform B, mounted. thereon, for the purposes set forth.
3. In a molding-machine, the spring-supported track, the rolling platform mounted 2o thereon, and suitable catches, I J, substantially as and for the purposes herein set forth.
4. A molders flask provided with a movable follow-board having a teat secured thereon, in combination with a spruecutting tube 25 adapted to work vertically through said board and teat, and united to them for such movement by a slot-and-pin connection, substantially as and for thepurpose herein set forth.
ELEAZER THOMAS.
