Application filed October 4, 1922.
ments in Molding Machines, of which the following is a specification.
The object of this invention is to allow workman greater freedom of movement and, therefore, enable them to work more rapidly in the occupation of making sandmolds with patterns.
In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur,
Figure 1 is a top plan view;
Figure 2 is a front elevation; and
Figure 3 is a side elevation.
For the kind of work mentioned above it is customary to spread a long pile of sand 1 lengthwise of a shop or similar lace and to straddle the same with the our wheels of av cart or wagon, and as th workman shovels the sand from the end of the pile l to move the wagon along the pile 1, always leaving the end of the pile protruding in about the relative position shown in Figure 3, which is forward of the rear wheels 2.
In this construction there is but one front wheel 3, but in the carts or wagons now in common use there are four large wheels like wagon wheels, and the workman is obliged to stand in the midst of them when doing his work, including shoveling the sand from pile 1. This greatly restricts and circumscribes his work, for one reason on account of the height of the wheels and for another reason on account of his being inclosed on two sides as well as in front of him. The present construction, having only one front roller 3, leaves two sides of the parallelogram open. This doubles the workmans efiiciency.
In this device the wheels or rollers 2 are unlike the wagon wheels of existing com mon usage, but are relatively low. Roller 8 is attached by trunnion 4 to frame -5 projecting forward from frame 6. Trunnions 7 connect the rear rollers 2 to brackets 8, depending from frame 6 and stiffened with relation thereto by braces 9.
The workman places his pattern box on Serial No. 592,302.
table 10 and beds it with sand. He places i the pattern therein, and shovels more sand. He then places the box upon platform 11 and admits air through air-pipe 12 from any suitable source of supply by means of levers 13. This causes platform 11 to rise and to press the pattern boX with its inclosedcontents of pattern and sand to rise until forced against the platen 1-1, the re sulting pressure thus compressing the sand for forming a sand-mold for casting.
The head 15 to which platen 14 is attached by screw 16 is rotatable, and, by means of screw 16, is adjustable.
Having thus described this invention, I hereby reserve the benefit of all changes in form, arrangement, order, or use of parts, as it is evident that many minor changes may be made therein without departing from the spirit of this invention or the scope of the following claims.
I claim:
1. A molding, machine, comprising a transverse bar having depending end portions, a traction wheel mounted on each de' pending portion, a longitudinal bar extending from one end of the transverse bar and forming with the latter a right angle frame, the forward free end of the longitudinal bar having a depending portion, a traction wheelsupported on the last mentioned depending portion, a table supported on the frameat the juncture of the transverse and longitudinal bars, a second table adjacent the transverse bar, means supported on the transverse bar to elevate the second mentioned table, a rotatable stand ard extending up from the transverse bar and provided with an arm, a platen mounted at the end of the arm. and means for raising and lowering the platen toward and from the second mentioned table.
2. A molding machine, comprising a transverse bar having depending end portions. a traction wheel mounted on each depending portion, a longitudinal bar extending from one end of the transverse bar.
and forming with the latter a right angle frame, the forward free end of the longitudinal bar having a depending portion, a traction wheel supported on the last mentioned depending portion, a table supported on the frame at the juncture of the transverse and longitudinal bars, a bracket extending from the transverse bar, a cylinder supported on the bracket, a piston in the cylinder, a second table supported on the piston, means for supplying the cylinder with fluid pressure to elevate the sec-. a 0nd mentioned table, a rotatable standard extending up from the transverse bar and provided with an arm, a platen mounted atthe second table.
the end of the arm and means for raising and lowerlng the platen toward and from -10 In testimony whereof-I hereunto affix my slgnature.
