DIE FOR SHEET-METAL PLATE S.
SPECIFICATION forming part of Letters Patent No. 616,976, dated January 3, 1899.
Application filed January 21, 1898. $erial No. 667,437. (No model.)
To otZZ whom it may concern.-
Be it known that I, LONGLEY LEWIS SA- GENDORPH, a citizen of the United States, residing at Philadelphia, in the county of Phila delphia and State of Pennsylvania, have invented certain new and useful Improvements in Dies for Sheet-Metal Plates; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention has relation to dies for pressing into shape metal plates for ceilings,walls, roofs, panels, 850., and has for its object the provision of means for facing and protecting the upper male or female die when made of soft metal, so that the durability of the latter may be greatly increased, its sharpness preserved, and a very great saving in the cost of die metal and its renewals and the labor incident thereto effected.
According to the present methods of constructing dies for pressing sheet metal, such as iron and steel for building and decorating purposes, a solid-steel female or male member is first cast with the upper-face bearing the configuration to be impressed in intaglio. male or female member is then produced by casting into the face of the steel member a molten composition or alloy of Babbitt metal with other metals, such as copper, tin, or antimony. The two dies or members are then arranged in a press, the upper die raised a sufficient distance to admit between the dies a sheet to be pressed or stamped,and the upper die then forced down, so as to produce the desired configuration in the sheet of metal in the usual manner. Dies so made and used have many disadvantages. Thus the soft metal for the upper die costs from ten to twenty dollars to ten dollars to the first cost of the die. Again, the soft metal of the upper die is so much softer than the steel of the lower die that the former in use rides the latter and,
invention.
by being displaced and distorted,becomes useless after pressing one hundred or two hundred' sheets. Re'casting in such instances is necessary, and even where this riding does not take place early in the use of the die the sharpness of the configuration is greatly impaired by the pressing of a limited number of sheets, so that the run is uneven,the last sheets failing to perfectly match the first or present a perfect pattern. My present invention is designed and adapted to overcome these and other defects, and to that end consists in adding to the soft-metal die a hard or comparatively hard and durable facing, which will last as long as the life of the lower die and entirely obviate the necessity of frequent, if any, renewals of the metal of the soft die.
In the accompanying drawings,Figure 1 is a sectional View of a pair of dies embodying my Fig. 2 is aplan view of the lower die. Fig. 3 is a plan view of the upper die, and Fig. 4. is a plan view of the facing-plate.
In carrying my invention into efiect I first produce the steel female die A in the usual Way, as by casting in a configured mold or by cutting the intaglio pattern in a block of steel, casting, however, being preferred as cheaper and equally suitable except for products of great firmness. I then cast into the steel die a male die B, formed of an alloy of any suitable character, adopting for such purpose the cheapest material obtainable and suitable, as there will be no wear or abrasion to be provided against and the high-priced alloys heretofore in use will be unnecessary. After finishing and fitting the dies to the press I proceed to form a facing for the upper die, and for this purpose take a sheet of some metal harder than the upper die, such as steel or brass, and hammer it closely into the depressions of the steel die until a perfect fit is produced, or I may press this sheet of hard metal into the steel die by the action of the upper die, preference, however, being given to the hammering operation, since it prevents injury to the soft metal of the upper die, which might ensue in using it to force a fiat hard-metal sheet into the depressions of the lower die. When this facing-sheet is perfected as far as can be by hammering, I force down the upper die until the facing-sheet fully conforms to the face of the upper die,
and then raising the upper die fasten the facing-plate to it, A being said facing-plate. The preliminary hammering of the sheet into the lower die may be dispensed with and the facing-sheet A produced by the first action of the two dies upon a commercial sheet of steel, which, being afterward fastened to the upper die, forms a face, held between which and the lower die the other sheets are pressed. I have carried this process and the use of these dies into practical and extensive Work and estimate that the Wear on the faced upper die is too small to be computed in any question of economy. I have been able with dies embodying my invention to press as many as forty thousand plates of steelwithont material depreciation in thequality or sharpness of the dies, so that the hard metal facing renders the life of the dies practically indefinite.
Should it happen that the hard-metal facing becomes imperfect from any cause, all
that is required is to replace it, but Without recasting the soft-metal body.
Having described my invention, What I claim as new, and desire to secure by Letters Patent, is-
1. A die for pressing metal plates consisting of a female member of hard metal, a male member of soft metal, and a facing-plate attached to the male member, and made of harder metal than said male member, substantially as described.
2. A die for pressing metal plates consisting of male and female members, one of hard and the other of soft metal, the soft-metal member being faced with a plate of harder metal, substantially as described.
In testimony whereof I affix my signature in presence of two witnesses.
