This invention relates to apparatus for and the process of casting metal articles, and is an improvement upon the invention disclosed in my patent, No. 1,701,559, issued February Like the invention disclosed in the application mentioned, the present invention has for an object the provision of means for casting unitary articles by means of a number of 30 stock patterns which consist of separate pattern units, so that a number of different articles may be cast without requiring the making of an individual pattern for each article.
One of the principal objects of the present invention is the provision of novel means for positioning certain of the pattern units so that they may be removed and replaced in carrying out the process.
lVith the above and other objects in view,
the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.
In the drawings Figure 1 is a plan view showing a portion of the bottom or mold board of a flask with a number of separate pattern units arranged in position.
Figure 2 is an edge view of the same, the mold board being shown in section and the guides partly covered with sand.
Figure 3 is a similar view With one of the pattern units removed and the sand in position preparatory to reversing or rolling over the drag,` part of the mold.
Figure 4 is a plan view of the bank of the mold after the under pattern units have been drawn from the bank and the other pattern unit repositioned.
Figure 5 is a section on the line 5-5 of Figure 4.
Figure 6 is a similar section after the superimposed pattern unit has been pressed into the bank.
Figure 7 is a plan view of the completed mold.
Figure 8 is a detail view of one of the pattern units.
Figure 9 is a detail'view of one .of 'the guides.
yindicates a portion of the mold board, which Vforms the bottom of the flask and in carrying Pout the invention, use is made of a number of separate pattern Vun'its'which are adapted to be positioned upon the mold board. These vpattern units may consist of letters of the alphabet to be-used in making monograms, as illustrated in the drawings, or they may consist of any ,other desired or suitable pat- Vtern units which a-re capable of being arranged to provide a. unitary article after the casing has been made.
Inexplaining the invention, use is made of pattern units 11 and 12, the former consisting of the letters T and F and the latter of the letter J, so as to provide a monogram consisting of the letters T J F. In making the monogram, the letters 11 Which consist of the letters T and F are placed upon the mold board side by side and the letter J is superimposed thereon. After the letters have been properly positioned, guides 18 are positioned upon the board. These guides are preferably formed of metal and comprise anchor blocks 14 from Which extend fins 15 and these fins are adapted to have their Outer eX- tremities engaged in notches 16 provided in the superimposed letter J. This letter J is then removed leaving the guides 1.3 in place and the flask is then filled with sand and tamped. The drag thus formed is reversed or rolled over and the mold board 10 is removed. The cope is then put on and ramm'ed up with sand in the usual manner, after which the cope is lifted ofi'. The letters T .90 and F which are embedded in the bank of sand are then drawn, after Which the letter J is again positioned so that the fins 15 engage within the notches 16 of the letter J, ais shown in Figure 4.
The letter J Will then occupy the position shown in Figure 5, after Which it is pressed into the bank as shown in Figure 6. This letter J and the guides 13 are then drawn from the bank and a gate 17 is formed in the .mn
V bank as Vshown in Figure 7 This fig'urel shows the finished'bank or mold havin 'the impression in thel sand'of the drag si ev of the mold and the latter is ready for the oope so thatfthe mold may be poured inl the usual manner. The'molded article ,Will form the mono vam TJ F whose configuration will be .su stanti'ally the', same as that shown in Figure 7 of the drawings; f
1 The inventlon 1s susceptible ofy various changes in its form', proportions and minor details of construction and the right is herein reserved to make'such changes xas properly fall within the scope of the appended claim..A Having described the invention what is claimed-isz--- I I Means for use in the proper positioning .of
` pattern units: for the casting ofV a composite of the units', embod'ying means for efiecting V the correct positioning'of one of the units with respect to another, the-said means compx'iising anchor blocks' for disposal in jfuxta- 'position tothefsaidother. unit,,and a finexg t'endinggfaromV one-'sideof each block toflbeenynotches in the unit to be positioned. n testimonyrwhereof I aflix my signature.
