Leftovers / At Death's Doorknob
“Leftovers” is a column that investigates the cultural significance of detritus.
Disposing of very large quantities of blood is an onerous chore. You can't give the stuff away—well, perhaps you can, but few are willing to endure the stares that proving this point entails.
Sawdust back then had already found use in papermaking and as a filling for dolls, and desperate Swedes had also figured out how to distill brandy from it. But these base ingredients of blood and sawdust remained plentiful, and were wonderfully effective when combined together as an animal polymer, the blood's albumen binding with the wood particulate. "Hemacite," noted the magazine, "is susceptible of a high polish, is impervious to heat, moisture, atmospherical changes, and, in fact, is practically indestructible." Starting out as brownish powder resembling snuff, hemacite could be molded into any shape and dyed to any color, and it became a popular and reasonably priced substitute for both wood and metal among architect and decorators.
In fact, by the time of the Manufacturer and Builder article, the Trenton headquarters of the Dibble Manufacturing Company had been for some years producing hemacite house trimmings and drawer pulls, and it now had a catalogue of hundreds of designs of their most popular product, hemacite doorknobs. The doorknobs carried a guarantee for the lifetime of the door, because rather than having a separate knob and shaft to wear out, they were molded as one unbreakable piece. It was a successful enough product that Dibble eliminated his own name from the enterprise entirely: Trenton became the proud home of the Hemacite Manufacturing Company.
Dibble branched out into products like hemacite cash register buttons and, quick to pick up on the latest fads, roller skates.3 "To skate manufacturers and dealers," boasted an ad in the 11 October 1885 issue of the New York Times, "the superiority of our Hemacite Roller over boxwood is now well known." The campaign seems to have worked: the 21 February 1903 Times carries an ad by the Siegel Cooper department store, hawking athletic supplies, and nestled among promotions for medicine balls and $12 Swedish Dogskin Coats ("For sporting use or driving") is an entry for 75-cent roller skates with hemacite wheels, a more expensive option than skates with plain "black wheels." Curiously, Siegel Cooper's ad appears over a plug for Plasmon Cocoa mix—"A blood-invigorating and muscle-making beverage of the highest order." Plasmon's active invigorating ingredient? Albumen, which was also the organic binding agent behind hemacite roller skate wheels.
W.H. Dibble was certainly an inventive fellow, having previously patented a dentist's contraption to simultaneously pry patients' mouths open while draining away their saliva, but his hemacite products were not quite the amazing innovation that he led others to believe.4 Like a true American, what he had really done was nick a foreign idea and improve upon it. Long before Dibble's 1877 application, the Parisian writer Francois Lepage secured an 1855 patent for what he called bois durci: a pressurized mixture of sawdust and cattle blood or, less economically, egg whites. Lepage founded the Bois Durci Company and exhibited its wares at the Great International Exhibition of 1862, back when Dibble was still tinkering with ways to suck the spit out of dental patients. Bois durci went on to turn up in a variety of 19th century inkstands, plaques, picture frames, and furniture; Edison even used it for the housing on early telephones.5 Even bois durci was not the first use of blood in buildings. Cattle blood had long been used in "blood cements," as, for that matter, had albumen from eggs, milk, and cheese. One Chinese recipe called for 100 parts slaked lime, 75 parts bullocks' blood, and 2 parts alum. Floors in South Africa gained a black marble-like polish with the use of blood, and an early London tennis court acquired its hard and glossy surface in the same way; it has even been used as an additive in roofing material.6 It seems there is no part of a house that cannot be manufactured, in part, from blood. Hemacite certainly captured the attention of Victorian architects. By the turn of the century, though, Dibble's firm had already suffered a factory fire, moved shop to a new building, and changed its name to Trenton Brass and Machine Company. The old Hemacite Company was as much a victim of changing times as fire: new plastics like Bakelite were in the offing, pushing aside the quaint notion of sawdust mixed with blood. The rechristened company soldiered on for many more decades, surviving the Depression and a postwar strike, and until recently still supplied fittings to plumbing contractors. But even Trenton Brass is gone now, and with it the last faint trace of Dr. W.H. Dibble and his Hemacite Company.7 But old hemacite house fixtures, strong and durable as they are, live on. So the next time you find yourself running short on bouillon, you may take this token of advice: consider boiling your doorknobs.
