Metal Feeders

For Linecasting, Typecasting, and Stripcasting Machines

image link-topic-sf0.jpg

The earliest reference I've been able to find for a metal feeder is US patent No. 636,622, issued 1899-11-07 to Delbert Zell Borne and James Frey. It fed solid pigs sequentially through a slide. The origins of the very popular Margach feeder go back at least to 1914, with US patent 1,175,466 (1914-03-14), issued to Andrew L. Margach for an "Automatic Feeding Device for Line-Casting Machines." However, the earliest advertisement I've yet found dates only to 1918 (for the Fort-Ified Electric Metalfeed), and the earliest catalog example is from 1936 (Linotype Catalog No. 27). As I would think that the need for a metal feeder would date back to the Bruce pivotal typecaster of the early/mid 19th century, this is most curious.

Note: The form of the ingot used (for ingot feeders) is of course important. Sometimes the ingot form is very closely related to the feeder (look at the "Linotype Metal Feeder," below, for example, which used a special notched ingot). In those cases it makes sense to include the ingot and its molds here with the associated feeder. In other cases, though, the ingot/mold may be used by a variety of feeders, and is really more closely related to the remelting equipment used. The "drop off" style of ingot developed by United American Metals in the 1930s for use with "Margach-style" feeders, for example, would work just as well with any other suspended-long-ingot feeder (Intertype, Star, etc.) In those cases, the ingot and its molds are covered in the Remelting Equipment Notebooks.

1. Systems Commercially Attested

These are feeders which were at least offered for sale (as attested by at least an advertisement, product announcement, or catalog listing).

Beard-Shot System

[TO DO: scan this] [ The Inland Printer Vol. 87, No. 5 (August, 1931): 96. has a brief note, illustrated. Typemetal was melted in an external unit (I think) and converted by it into shot. This was fed into the pot through a hopper.

Fort-Ified Electric Metalfeed

[TO DO: transcribe] [See Inland Printer, v 60 n 6 (March 1918).] [US patent 1,226,651 1917-05-22, George L. Fort.] (Fort also designed a sort of an electric Linotype pot throat heater which could be applied to electric or gas pots (US patent 1,127,682, 1918-09-24))

Intertype (UK) Metal Feeder

Ashworth, J. Operation and Mechanism of the Linotype and Intertype p. 205 shows a feeder made by Intertype in the UK (Slough, Buckinghamshire) which differs from the US Intertype feeders.

Streamline Automatic Metal Feeder

A reference in the 1953 Western Newspaper Union catalog. Also a handy Ingot Hanger for hanging five spare pigs on the side of the machine.

Note: The 1927 Miller Saw-Trimmer book bears a Miller Saw-Trimmer Company logo which claims that they build both "saw-trimmers" (printer's saws) and "automatic feeders." This is not, however, a metal feeder. It is a paper feeder for platen presses. See Hackleman, Charles W. Commercial Engraving and Printing 2 ed. (1924): 462. for illustration.

2. Other Systems

These are feeders for which I've discovered some documentation (usually a patent), but not yet any indication that they were produced. Of course, this doesn't mean that they weren't produced - just that I haven't found the reference yet.

Curle Pot Puddler

US patent 1,669,456, "Puddling Device for Type-Casting Machines," issued 1928-05-15 to George L. Curle. Filed 1925-05-01 as application serial number 27,224. This is a pot agitator. I've classified it here, with metal feeders, because it looks as if it would work well with the relatively open pot of a Monomelt. It would be much more difficult to fit directly into the crowded pots and crucibles of Linotypes, Ludlows, Thompsons and the like.

George Curle was most closely associated with the Monomelt. See that Notebook for an index of Curle's inventions covered in CircuitousRoot.
