Similar letters refer to similar parts where- D is the head or upper end of the sash- 10o weight, having a lateral perforation D going completely through the head from one side to the other and communicating with the conical or tapering end perforation D by which arrangement the sash weight is rendered equally useful for attaching to it a cord, chain, or tape, as may be desired.
D in Figs. 10 and 12 represents raised or recessed marks or figures on the head D for the purpose of indicating the weight, size, or number of the weights, as usual.
The head-molding device is fully shown in Figs. (3, 7, and 8, and it consists of a series of head-patternsG G, secured at distances apart equal to the distances between the respective patterns (1 (Z in the flask a. The said headpatterns G G are secured to a bottom board G, upon which is loosely placed and properly guided a hollow rectangular frame II, to the under side of which is secured a perforated sand -lifter plate h, having perforations h, through which the l1ead-patterns G may pass easily. \Vithin the said lifter-frame II is located the removable head-mold frame I, having lateral divisions it between the headpatterns G G, as shown. The said frame I is open from top to bottom and has its lower edge resting loosely on the upper side of the sand-lifter plate It, as shown.
The bottom plate G has a longitudinal groove, in which is. arranged the adjustable bar K, to the upper side of which are secured a series of mark-patterns 70, adapted to be moved out of the. way into recesses g g in the body of the head-patterns G G when the frame I and the sand within it is withdrawn from said head-patterns after the sand-molds have been made.
For the purpose of ramming the sand in the spaces inclosed between the. interior of the frame I and the head-patterns G G, I prefer to use a ramming-tool, as shown in Fig. 9, consisting of a plate I having attached to its under side a series of cylindrical tubes Z l, provided with cut-away portions Z Z at their lower ends to enable the sand to be rammed into the frame I around the head-patterns G G and their projecting core-prints G G. (Shown in Figs. 6 and 8.) After the sand has been properly rammed into, the spaces between the head-patterns G G and the interior of the frame I it is struck off even with the top edge of the latter. The bar K, with its mark-patterns 7; 7a, is then moved in the direction of the arrow shown in Fig. 7, causing said mark-patterns 7c to enter the recesses g g in the head-patterns G G, thus enabling the frame I and its sand-molds to be withdrawn from the head-patterns G G without disturbing the impression made in the sand by the mark-patterns 7t 7c.
The frame I is removed from the head-patterns by raising the frame II and its perforated bottom plate h, upon which the frame I and molded sand is supported, after which the frame I is detached from the frame H and ready for receiving the cores for the formation of the head cavities or recesses.
70 k are catches or buttons on the opposite ends of the sliding bar K for the purpose of holding it in proper position 011 the board G during the process of ramming the sand within the frame I.
By releasing the catch k the bar K may be moved in the direction of the arrow shown in Fig. 7 preparatory to the removal of the frame I and its molded sand.
In using the improved flask for molding and casting seamless sash-weights I proceed as follows: The flask a a is placed on the moldboard 19, the gate-pattern 6 passed through the perforations in the sides of the flask, and the sash-weight patterns d d laid in position, as usual, in parallel rows upon the recessed pattern-supports b b b 19 after which the recessed bars I) b are placed on top. of the pattern end supports 19 b and the location of such pattern end supports 19 I) adjusted by set-screws f f on the detachable bars ff, as fully shown in Figs. 1 and 2, the bottom board 0, however, being removed. The operator now rams the sand in the flask, as shown in Fig. 2, and strikes it off even with the upper edgeof the flask. The bottom board 0 is then placed on top of the flask and the whole clamped together by meansv of clamps q q or other suitable clamping devices, as shown in Fig. 3, after which the flask is reversed to the position shown in Fig. 4 and the moldboard I) removed. The sprite-pattern r isinserted and the sand rammed and tucked under the bars a a a a, as shown in Fig. 4. I then draw out the center gate e and fill up the openings in the side of the flask through which said gate was originally inserted. I then draw out the patterns. at 01 toward the opposite ends of the flask and remove the guide-boards ff and lift away the recessed pattern-supports b I). In place of the pattern-supports b b I place the frames I I, containing the sand-molds. and cores for the formation of the perforated headsv of the sashweights, and insert the back boards A A in the grooves a a back. of said frames I I and ram and tuck the sand on top and bottom of said frames I I, as fully shown in Fig. 5. After removing the s prue-pattern r the molten metal is poured in through the sprue-hole r, as is common in the art of casting. After being cooled the sash-weights are broken off from the metal connecting the inner tapering ends, leaving said weights in a finished seamless condition, as shown in Figs. 10, 11, 12, and 13.
\Vhat I wish to secure by Letters Patent and claim is- 1. In a device for molding sash-weights, the combination with a longitudinallygrooved bottom board. G", of a series of head-patterns G secured at equal distances apart to the bottom board and each having a laterally-extending recess formed in one side, a longitu- IIO dinally-movable bar K fitted to slide in the said groove in the bottom board, and a series of mark-patterns 70 secured to the movable bar K and fitted in the recesses in the headpatterns, whereby said mark-patterns may be simultaneously moved into said recesses when the patterns are withdrawn from the mold, substantially as and for the purpose set forth.
2. In a device for molding sash-weights, the combination with a 1ongitudinally-gro0ved bottom board G, of a series of head-patterns G secured at equal distances apart to the bottom board and provided upon their corresponding sides with laterally-extending recesses, a longitudinally-movable bar K fitted to slide in the groove in the bottom board, a
series of mark-patterns is secured to the bar K and fitted in the recesses in the head-patterns, a frame H surrounding the head-patterns, a perforated sand-lifter plate 72 fitted over the head-patterns, and a sand-receiving frame I seated 011 said sand-lifter plate, sub stantially as described and for the purpose specified.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 8th day of October, A. D. 1895.
