JOHN D. JOHNSON, OF HAINESPORT, NEW JERSEY.
VIMPROVEMENT VIN MOLDING PIPES.
Specification forming part of Letters Patent No. 133,584, dated December 3, 1872.
To all whom'it may concern.'
Be it known that I, JOHN D. JOHNSON, of Hainesport, in the county of Burlington and State of New Jersey, have invented certain Improvements in Molding Pipe-Fittings, Ste., of which the following is a specification:
My invention relates to the combination of half patterns of branch pipes, elbows, Or other card which is beneath the 4follow-board being connected by hinges E E. Fig. 2, Sheet No. 2, is a longitudinal section at the broken line w w of Fig. l.
Like letters in both gures indicate the same parts.
A is the card. B B are half patterns of a branch pipe, conned on pedestals G, that are permanently connected with the card equidistant from the middle of the same. D is the follow-board. It has openings, et, which tit over the pedestals @and when in position on the card, as represented in Fig. 2, its upper surface coincides with the upper sides of the pedestals and the at or middle surface of the patterns connected with the same. The followboard D is connected with the card A at one end by means of the hinges E E, to provide for conveniently raising it to relieve the mold from the patterns, and afterward returning it to its former connection with the card and patterns, which it assumes in Fig. 2.
The operation is as follows: The followboard D being in its lowest position, as represented in Fig. 2, and lying flat upon the card A, and the openings a fitting closely around the patterns B B, the drag part of the flask is laid thereon,loeing held accurately in place by means of dowels, or otherwise. Then the sand is rammed around the patterns in the usual manner, and the follow-board turned ou its hin ges until the mold is raised freefrom the patterns. Then the free end of the follow-board is propped up in any convenient manner, and the drag removed therefrom and turned over, ready for the reception of the cope. The follow-board is then brought down to its former position and the cope connected therewith, and, after the molding has been completed, removed in like manner as the drag from the patterns, and connected with the drag.
I make the card and follown board long enough to place the hinges at such a distance from the front edges Of the patterns as may be necessary to prevent the breaking ofthe sand as the mold is swung o the patterns.
I have represented but a single pair of patterns, but it will readily appear that any convenient number may be used.
I have represented in the drawing branchpipe patterns, yet it will be seen that the invention will equallyapply to other tttin gs and to other descriptions of castings.
I claim as my invention- The hinged connection of the followboard D with the card A, the card being provided with patterns mounted on stationary pedestals C and the follow-board with openings a, substantially in the manner and for the purpose above described.
