MACHINE FOR MOLDING ARTIFICIAL STONE.
SPECIFICATION forming part of Letters Patent No. 703,452, dated July 1, 1902.
Application filed April 22, 1902. Serial No. 104,144. (No model.)
To all whom it may concern.-
Be it known thatI, NoYEs F; PALMER, a citizen of the United vStates, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Machines for Molding Artificial Stone, of which the following is a specification. r
This invention relates to an improved machine for molding artificial concrete building and paving blocks, and more particularly to. an improved construction ofadj ustable coresby means of which the machine may be readily set to turn out blocks of various sizes andconfigurations.
In the accompanying drawings, Figure l is a side elevation of myimproved machine for molding artificial stone; Fig. 2, a top view of the core-support; Fig. 3, a top view of the mold-box with the false bottom removed; Fig. 4., a longitudinal-section taken on line 4 4, Fig. 3; Fig. 5, a cross-section'on line 5 5 Fig. 3; and Figs. 6 and7are perspective views illustrating .two of the forms of blocks that may be molded by the machine.
The letter a represents theframe of-the' machine, and a is the base-plate that forms the bottom of the mold-box. The sides I) and ends 0 of the mold are adapted to slide upon the base-plate, soas to open or close the mold.
This movement is effected from shaft 61 bybevel-gear d and. racks b 0, such construc-' tion, however, not forming part of the present invention.
The base-plate a has a central opening adapted to accommodate a longitudinallyslotted plate e, that constitutes a support for the cores f used in making hollow blocks;
These cores are adapted to be removably and adjustably secured to thesupporte, so that end of each bolt carries a nut countersunlnwithin the top plate of the core. By
slacking the nut the core is unlocked from the base-plate and may be shifted along the same by sliding the bolt along the slot e until the core arrives at its new position, when it may be relocked by tightening up the nut.
Thus it will be seen that the cores may be readily, adjusted and that the locking and unlocking mechanism is readily accessible 'from the top of the machine.
Each core is preferably subdivided transversely into two sections for the introduction of transverse partitions h, used in molding blocks shorter than the mold. In order to permit the molding of .blocks narrower than the mold, I employ longitudinalpartitions h, which are inserted between adjoining cores. To this effect the cores are provided with grooves f, that face each other and into which the partitions may be slid. The ends 0 of the mold may alsobe grooved, as at 0 to engage the last partition, and they may likewise be provided with'curved projections or cores 0 if a block with a curved end is to be molded. Thus with thesetting of coresandpartitions indicated in Fig.4 3 two blocks A, Fig. 6, will be turned out by the left half of-the mold, while one block B, Fig. 7, will be turned out by the right half.
The support 6 may be made vertically movable, so that the cores may be Withdrawn downward fromout of the mold. This move ment is effected by a shaft 1', pinions i, and racks i Upon the mold-bottom a is placed a false bottom j,,which is perforated to accommodate the cores and cover the exposedsection of slot c This false bottom may be raised so as to discharge the finished block over the top of .the .mold, the vertical movement being imparted to itfrom shaft 2', through pinions j,
and racks 9' that of base-plate a. p a
It will be seen that by my invention the mold may be set to shape a large variety of blocks and that the adjustment of themold can be effected in a simple and convenient manner. 4
What I claim is- 1. In a machine for molding artificialstone, the combination of a mold with a slotted supporting-plate, an adjustable core, and a bolt pass throughopenings a ICO 4. In a machine for molding artificial stone, the combination of a mold with a slotted supporting-plate, an adjustable grooved core, a bolt extending through the core and engaging the slotted plate, and a partition engaging the core-groove, substantially as specified.
Signed by me at New York city, New York, 20 this 21st day of April, 1902.
