MATRIX MOLDING DEVICE.

hold the printing rules in place. Another object is to provide such molding devices with capacity for strengthening the projections by molding metal braces for the projections integral therewith. Other objects I are to provide molding devices which will exclude the composition metal from the working parts of the molding devices.
Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.
Reference is had to the accompanying drawings which form a part of this application. Figure 1 is a side elevation of a matrix which is equipped with the operating improvements. Fig. 2 is plan view of the same. Fig. 3 is aside elevation of the same, partly broken away to expose the operating improvements. Fig. l is a vertical section, taken substantially on the line 03-00 of Fig. 3. Fig. 5 is a perspective view lof the former. Fig. 6 is a broken side elevation of a slug, showing the projections or ruleholding members on the slug. Fig. 7 is a broken plan view of the same, showing the bracing for the rule-holding members.
Similar characters of reference are used to indicate the same parts throughout the several views.
The drawings show a matrix of ordinary type to which the improvements are applied. A former 2 is countersunk in the upper edge of the matrix 1. The former 2 is pivotally mounted in the matrix 1 by means of depending integral bearing member 3 which projects down into a cavity 4 formed in the Specification of Letters Patent.

show the former 2 in the normal operating M position. The spring 5 is provided for holding the former in the working position, but
permitting a yielding motion of the former so that it can be removed from the formed slug. As soon as the slug is removed, the spring 5 will restore the former 2 to working position. The particular part of the former that aids in making the overhanging projection 7 on the slug is the tip 8 with the beveled under cut edges thereof which together with the portions of the matrix adjacent thereto provide the angular spaces 9 to receive the molten metal. Portions of the top of the matrix are cut away at 10 to receive molten metal which will form braces 11 on the slug which braces will be integral with the overhanging projections or rule-holding members 7. At other points than the position of the projections 7 the former 2 is made wide enough,co-extensive with the top of the matrix, and long enough to prevent metal from entering the cavity 4 which would interfere with the operations of the spring 5 and the bearing member 3. Various changes in the sizes, proportions, and construction of the various parts may be made without departing from my invention.
Each device will form a pair of projections 7 and a series of the devices may be used to form a series of projections. When one of the devices is placed in the mold holding devices, it will form a pair of projections 7 with the adjacent sides of the proj ections overhanging, as shown, but the outer sides of the projections would be determined by the forms of the holding devices.
What I claim is,
1. In a matrix provided with a cut-out and a cavity in said cut-out, a former mounted in said cut-out and having a pivotal connection projecting down in said cavity and having its upper surface flush with the upper surface of said matrix and co-extensive in width therewith, means for holding said former yieldingly in place, and a former tip on said former having under-cut beveled edges forming angular spaces to receive material for forming projections.
2. The combination with a matrix having a portion of the upper surface cut away and having a cavity formed therein, of a former mounted in the cut-out in said matrix and having its upper surface flush with the upper surface of said matrix, a bearing member integral with said. former and projecting down into said cavity, a pivot bolt connecting said bearing member to said matrix, a former tip on said former having under cut edges forming angular spaces with said matrix to receive material for forming projections on slugs, and a spring for holding said former yieldingly in place and for restoring the former to working position.
3. The combination with a matrix having a portion of upper surface cut away for a former and having a cavity formed therein, of a former mounted in said matrix and having its upper surface flush With the upper surface of said matrix andco-extensive in width therewith, a bearing member in-' tegral with said former and projecting down into'said cavity, a pivot bolt connecting said former'to said matrix, a spring in said cavity for holding said former yieldingly in position and for restoring said former to Working position, and a former tip on said former having under-cut beveled edges forming angular spaces with said matrix to receive material to form projections, said matrix having portions thereof cut away to form recesses for receiving material to form braces integral with the projections.
In testimony whereof, I set my hand, this 18th day of November, 1916.
