ROTARY LAYOUT STAND This invention relates to pattern making, and more particularly to a rotary layout stand for use in the manufacture of patterns.
In the manufacture of patterns for use in the preparation of cast or machined elements, it has been the practice to just prepare a master pattern constructed of wood based upon drawings and specifications. Thereafter, a second pattern constructed of a metal, such as aluminum or steel corresponding to the wooden pattern is prepared.
' It is then necessary to carefully compare the metal pattern to the drawings to insure that the dimensions of the metal pattern are precisely the same as those of the drawings. For this purpose, the metal pattern is mounted on a match plate and the dimensions compared by means ofa height gage positioned on a surface table. The height gage is set to measure a vertical dimension on the adjacent metal pattern on the match plate to determine if the corresponding vertical dimension on the metal pattern is the same as the drawing. The process is then repeated to check and verify all of the vertical dimensions.
To check the non-vertical dimensions of the patterns, it is necessary to position the match plate such that, for example, the horizontal dimensions can be measured on a vertical axis. For this purpose, pattern makers have mounted the match plate on what is known to the art as a knee" in the form of a pair of metal plates welded together at right angles. Thus, the pattern maker must unclamp the match plate from the knee and turn it sideways for re-clamping to the knee for further measurements. The procedure of removing the match plate from the knee and re-attaching it to make all of the necessary measurements not only contributes to the possibility of error, but is also tedious, time consuming and frustrating.
It is accordingly an object of the present invention to provide a rotary layout stand for use in pattern making which overcomes the foregoing disadvantages, and it is a morespecific object of the invention to provide a layout stand for use in comparing match plates in which all measurements can be made without removal of the match plate from the stand.
It is a further object of the present invention to provide a layout stand for use in comparing match plates which enables measurements to be made in a more efficient manner which substantially minimizes the possibility of error.
These and other objects and advantages of the invention will appear more fully hereinafter, and, for purposes of illustration, but not of limitation, an embodiment of the invention is shown in the accompanying drawing in which:
FIG. 1 is an elevation view showing one face of the layout stand of the invention;
FIG. 2 is a side elevation view showing the side of the device of FIG. 1;
FIG. 3 is a bottom view taken along the line 3-3 in FIG. 1;
FIG. 4 is an elevation view of the layout stand of FIG. 1 showing the opposite face;
FIG. 5 is a sectional view taken along the line 5-5 in FIG. 4;
FIG. 6 is a sectional view taken along the line 6-6 in FIG. 1; and
FIG. 7 is a schematic illustration of the use of the layout stand of the invention in measuring a match plate.
The concepts of the present invention reside in a layout stand for use in pattern making which comprises a base and a circular panel having a central opening for mounting a match plate thereon. The circular panel is rotatably mounted on the base, and thus the match plate mounted on the circular panel can be rotated with the panel to enable measurements of all of the dimensions to be made without removing the match plate from the layout stand. Thus, the layout stand of the present invention completely obviates the need to continually remove the match plate from a knee or the like to make further measurements, and consequently assures greater accuracy in making such measurements.
Referring now to the drawings for a more detailed description of the layout stand of the invention, there is shown in FIG. 1 a layout stand embodying the features of the invention. The layout stand comprises a base 10 in the form of a base plate 12 having a substantially semi-circular cavity 14 formed therein which is maintained in a vertical position by means of legs 16. Mounted on one side of base plate 12 along the cavity 14 are at least a pair of roller means 18 which are positioned such that the peripheries of the roller means extend beyond the wall of cavity 14 on one face of the base plate 12.
A circular panel 20 having a central opening 22 extending therethrough is mounted in the semi-circular cavity 14 with the periphery of the panel 20 resting upon roller means 18. In this way, circular panel 20 is rotatable on bearing means 18.
One face of the circular panel 20 is provided with a slot 24 extending about the periphery of the face as shown in FIGS. 4 and 5. In the preferred embodiment .as shown in FIG. 5, the slot 24 is formed a continuous recess 28 defined by the plate 20 having a slightly smaller opening 24 on one face of the circular panel and thereby forms a T-slot. Thus, the recess 28 is adapted to receive nut means 30 dimensioned to fit therein, but dimensioned to be retained in recess 28 by the smaller opening 26.
Aligned with the slot 24 in the face of the circular panel 20 are one or more openings 32 extending through the base plate 12 which are adapted to receive screw means 34. As illustrated in FIG. 5, screw means 34 is preferably in the form of a plastic nob screw which is inserted through opening 32 in the base panel 12 and through opening 26 for threading engagement with nut means 30 positioned within recess 28. When screw 34 is tightened on nut 30, the nut 30 is tightened against the surfaces 36 of recess 28 to thereby lock the circular panel 20 and prevent rotation of same. It is generally desirable to employ two or more of the locking screw assemblies illustrated in FIGS. 4 and 5.
Similarly, when it is desired to rotate the circular panel 20, the screw means 34 is loosened to release the nut means 30 from locking engagement with surfaces 36. Thus, nuts 30 positioned within recess 28 are free to slide through recess 28 to permit circular panel 20 to be rotated.
The details of the roller means 18 are more clearly illustrated in FIG.-6 of the drawings. As can be seen from this figure, the roller means preferably includes a roller 38 mounted upon a sleeve 40. It is preferable that the roller 38 be carried by ball bearings or the like-to minimize friction as circular panel 20, with its periphery in contact with roller 38, is rotated on roller 38.
In use, as illustrated in FIG. 7 of the drawing, a match plate 42 containing patterns 48 and 50 is mounted on the circular panel by suitable mounting clamps 44. The match plate 42 is mounted over the central opening 22 of circular panel 20 to permit access to both sides of the match plate for making measurements. Such measurements can be made by a suitable measuring device 46 to determine that the vertical dimensions of the matchplate 42 precisely match, each with the other.
After all of the necessary vertical dimensions on the match plate have been verified, the screws 34 are loosened to permit the circular panel 20 with match plate 42 fixed thereto to be rotated to enable all dimensions to be measured and verified on a vertical axis by way of the measuring device 46.
For this purpose it is generally preferred that the circular panel 20 be calibrated in 360 about its peripheral surface 52. Such calibrations are shown in FIGS. 2 and 3 of the drawing and permit, with the aid of a Vernier scale 54 on base plate 12 as shown in FIG. 1, the degree of rotation of circular panel 20 to be determined.
It will be apparent that l have provided an improved layout stand for use in pattern making which significantly reduces the handling of match plates in the measuring and verification of the dimensions thereof. The layout stand of the invention not only reduces the tedium of such measurements, but also serves to significantly reduce the possibility of error.
It will be understood that various changes and modifications can be made in the details of construction and use without departing from the spirit of the invention, especially as defined in the following claims.
