ZABINA ELLIS, OF PHILADELPHIA, PENNSYLVANIA.
I Letters Patent No. 98,676, dated January 11, 1870.
c,- mnovnmn nr 11v meson ron sncunme cones m MOULDS.
The achedule refened to in these Letters Patent and making part0! the same.
To all whom it may concern:
Be .it known that I, ZABINA ELLrs, of Philadelphia,
Pennsylvania, have invented a new and u seful Mode 'of Securing Cores in Mouldsifor pipe-castings; and
beingcored and rammed up in the usual manner, .the I core, however, being secured from the upperside, ace cording to my improved mode- Figure 3.is a longitudinal vertical sect-ion of a similar flask, similarly cored and. rammed up, the core being also shown as secured by myimproved mode.
In casting iron pipes, some plan of securing the core, to prevent its rising in the mould, wh'enthe molten metal is introduced, has to be employed.
The, core is supported from below by the sand in the flask, or by metallic sockets in the sides of the I flask, orby anchors, two or more, such as are shown at g, fig. 2, and to secure the 'core from above, an anchor, similar to the anchor g,has been, or several such anchors have been, hitherto employed.
V In such case the curved head of each anchor abuts against the loam of the core, and the leg of the anchor being projected through a hole in the cope or topah-alf of the flask, is held down-by a'clamp, one form of which is shown in fig. 2.
-Ihisrmode oi anchoring cores I have found "to, be
defective, in this, that the pipes so castare of uneven, and uncertain thickness, being thicker in those. parts formed in the'lower part of the mould, and thinner in opposite parts. This defect'is due to the imperfect mode of anchoring from the cope; The cop'eeanchor not being in contact with the solid spindle oi. the core,
permits the 0UI6'.I70 rise from the yielding of its .hay
rope and loam as the molten metal is poured into the mould. v
I obviate these defects, and secure the castingof pipes with even thickness, by employing an anchor, which can be inserted through a hole in the cope, and driven through the loam and hay rope of the core' directly against the metallic spindle oi the core, as represented in figs. 2 and 3.
Referring to-the drawings a represents the cope, and b, the drag, or upper and lower halves, respectively, ot'the flask. c, the metallic spindle ofthe core.
(I, the hay rope, wound about the spindle.
e, the loam, which coats the hay rope.
f, the'spaee 'forthe metal;
g, the anchor, havinga'curved head for supporting the core, from the drag, in its place in themould.
71;, an anchor, such as I employtor securing the core from the upper side.
i, a clamp, and j, a wedge, for holding the anchor 71- in place. ,The driving-end of'the a'nchoi lait will be seen, has increased thickness, forming a shoulder at. It, figfil. I prefer-to give it this form, with the. view of increasing its powerl of resistance against the action of the .hot
meta-1.: This form I employ in'castiug pipes of twelve inches diameter, and other heavy pipes but for light pipes, or pipes of less diameter,-the 'anchorh may-be of a continuous taper from the driving-end, or it may, in either case, be in the form of a barof small diameter, cylindrical froi'n'jend to end; butin thisform-it cannot-be so readily driven through the loam and hayrope; 1
Having thusdescribed my invention, I claim, and-desire to secure 'by Letters Patent-v .The anchor 71-, constructed in the" manner and 'for the purpose substantially as set forth.
' ZABINA ELLIS.
