HOLDING-MACHINE PATTERN.
SPECIFICATION forming.;` part of Letters Patent No. 632,247, dated September 5, 1899.
Original application filed December 19. 1898, Serial No. 699,720. Divided and this application tiled May 3l, 1899. Serial No. 718,867. (No model.)
T0 a/ZZ whom, it 71u17/ cm1/06772,:
Be it known that I, HARRY C. COOPER, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Molding-Machine Patterns; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same,referencc bein ghad to the accompanying drawing,\vhicl1 forms a part of this specification.
My invention has for its object the production of a molders pattern for forming a sand mold for use more particularly in connection with the machine shown and described in my concurrently-pending application filed December 19, 1898, Serial No. 699,720, of' which this application is a division. In my said previous application I have shown and described a machine comprising stationary pressure mechanism located above the flask and mechanism for supporting the ilask and patterns adapted to move upward toward the stationary pressure mechanism, and thus compress the sand between the stationary pressure mechanism and the patterns. This patternmoving mechanism is so arranged that the u pward movement of the various sections may be made intermittent.
The obj ect of the present invention is to provide a pattern so arranged that the different sections of the pattern may be carried by any one or more of the pattern-supporting parts.
The invention will be hereinafter more fully described and claimed.
In the drawing the figure is a 'vertical section through the patterns and adjacent parts of the machine.
In carrying out the invention, A represents the cope portion of a flask, and B the part Which directly supports the flask. In the present case I have shown apparatus for forming a car-Wheel mold, and the flask-support B in this instance constitutes the chill for the mold, so that it is in reality a part ot' the flask.
C is a chill-support or flask-support proper carried by the ring D and the latter threaded to the ring E, which is carried from the standscribed thc mechanism for moving upward any of the parts, such as the flask or the dit'- ferent pattern-supporting parts. It will of course be understood that I do not limit myself to any particular mechanism, although that shown in my prior application will accomplish the purpose.
F F F2 F3 F4 F5 FSF7 FS F F10 Fl1 represent the different pattern-supporting parts, each provided with any suitable mechanism for moving` it upward either simultaneously with any other part or. at different intervals with respect to each other.
G G Gr2 represent the' different sections of the pattern. As mentioned above, I have for purposes of illustration shown and described a car-wheel pattern; but it is obvious that my invention is applicableto any form or shape of pattern and to a pattern divided into any desired number of sections.
At this pointl desire to call attention to the fact that in my present claims I have referred to the pattern as a unitary structure. By this term I mean that the pattern or pattern part is a unit and movable as such, or, in other words, While in order to form a completed mold several pattern-sections may be employed and the pattern as a whole thus be made up of more than one piece, yet the claims relate to a section which moves as a unit and is therefore a single piece or section Whether in its composition it is made of a single integral piece or several pieces united to form a unitary structure.
In the operation of the machine in which my patterns are used it frequently happens that a section of the pattern has to be carried upward for a distance on one of the pattern-supporting parts and then picked up by another of the pattern-supporting parts and carried on upward. It also frequently happens that for a portion ot' the upward movement one of the pattern-supporting parts will be carrying more than one section of' the pattern and that it is desired to have that particular pattern-supporting part remain stationary for a period in order to allow one of the pattern parts which it carries to remain stationary. In that event theother patternsection on that particular supporting part, which said pattern part it is desired to have IOO continue to advance, is provided with another bearing-surface in line With another patternsupporting part,whicli continues to move upward, While the first-named pattern-supporting part stands still, so that the pattern-section which it is desired to advance will be picked up by the continuously-moving supporting part and carried on upward. The various bearing-surfaces on the various sections of pattern may be arranged in innumerable Ways, and I have therefore illustrated only a few of them.
'Referring now to the section G, it will be observed that itis provided at G3 with abearing-surfacein vertical alinernent with the Section F of the pattern-supporting mechanism, while at G4 it is provided with a bearing-surface in line with the pattern-supporting section F. In this instance the tWo lugs orbearing-surfaces on the pattern-sections are shown integral therewith or Xed thereto. They might, however, be made adj ustable--as, for instance, by means of a set-screw G5, (shown in connection with the section G of the pattern and in vertical alinement with the pattern-supporting part F3.) The same section of pattern has a bearing-section GG in vertical alinement with the pattern-supporting part F4. At G7, I have shown a 'bearing portion in the shape of a screw-ring adjustable on the section Gr2 and in alinement with the patternsupporting parts F5 F7. This section is also provided at GS with another bearing-surface in line with the pattern-supporting part F6. Instead of making the bearing-surfaces on the pattern-sections adjustable the bearingsurfaces of the pattern-supporting parts might be made adjustableas, for instance, by means of the screws GrJ in the pattern-supporting part F.
All these various changes and combinations, as well as many others, might be made without departing from the spirit of the invention, which consists, essentially, in providing a pattern part with two or more bearingsu rfaces out of vertical alinexnent with each other and also out of horizontal alinement with each other, so that the pattern-section will be picked up by that supporting part which will give it the desired movement, and in providing between a pattern supporting part and a section of the pattern an adjustable surface or bearing portion, so that no matter whether the adjustable surface is on the pattern-supporting part or on the pattern the pattern Will be picked up at the desired time or carried at the desired height from the pattern-supporting part.
In addition to the above features of the invention it will be observed that I have provided guide-rods G10, engaged to the pattern part and extending through orifices in the pattern-supporting parts, so that the patternsection will be properly held in alinement during its movement.
What I claim isl. The combination with two or more movable pattern-supports ot' a molding-pattern f unitary structure provided with two or more supporting or bearing surfaces or members said members being out of vertical and out of horizontal alinemeut with each other, substantiall y as described.
2. In a molding-machine the combination with two or more pattern-supporting parts movable with respect to each other, ot a patternor pattern part of unitary structure provided witha bearing member foreach of said pattern-supporting parts, the bearing mem-- ber between at least one of the supporting parts and the pattern being adjustable, substantially as described.
In testimony whereof I sign this specification in the presence of tWo Witnesses.
