The neighboring towns of Hubbard and Warren in Ohio were home to two related evaporator companies in the late 19th and early 20th century, Henry Hescock’s Eureka Evaporator and Milton Mathews’ I.X.L. Evaporator.
Eureka Evaporator
The Eureka Evaporator, the earlier of the two, was invented and manufactured by Henry W. Hescock, out of Hubbard, Ohio. Following service in the Civil War at the age of sixteen, Hescock entered the dry goods business with his father-in-law, Edward Moore, in Hubbard, Ohio from 1866 to the late 1870s. Following the dry goods business, he started an evaporator manufacturing business, although it is not clear exactly when Hescock began to design and manufacture evaporators. One source says he opened his evaporator shop “shortly after the war” and another mentions upon his death in 1896 that he had been making evaporators for over twenty years. The earliest reference to him patenting one of his evaporator designs dates to 1877.
References describing the actual use of this evaporator as well as advertisements for the sale of the Eureka Evaporator appear as early as 1883. It is important to note that the Hescock Evaporator should not be confused with an entirely different fruit evaporator, also called the Eureka, that was manufactured in the late 1870s and early 1880s by Mr. D.R. Byrum and the Grand Isle Evaporator Company, out of Grand Isle, Vermont.
The first Hescock evaporator patent from 1877 (patent no. US195366) featured a series of individual flat pans joined by connecting siphons. Hescock’s second patented design, awarded in 1886 (patent no. US335583), featured the same siphons with the addition of corrugations to the bottom of the pans to increase the surface area exposed to the heat of the firebox. In 1893 he patented a third evaporator design (patent no. US50233) which featured a unique set of horizontal tubular flues through which the hot gases would flow as they exited the fire box and out through the stack or chimney. Hescock obtained this patent in 1893 but there is no indication that he put this design into production.
In addition to manufacturing evaporators, Hescock sold sheet metal sap pails, a barrel style sap tank, and a sap level regulator. Besides manufacturing maple sugaring equipment, Hescock co-owned the Loveless & Hescock foundry with his brother-in-law Warren Loveless. Hescock and his wife also owned numerous parcels of land in Hubbard with Hescock listed as the builder for at least fourteen houses in the town of Hubbard.
Based on a number of advertisements, envelopes and letterhead, and other references from that era, the Eureka Evaporator was actually fabricated at Milton Mathews’ Warren Evaporator Works in nearby Warren, Ohio as early as 1884.
It is possible that the Warren Evaporator Works simply had a license to manufacture and sell the Eureka Evaporator alongside their I.X.L. Evaporator and Hescock himself was simultaneously engaged in fabricating his Eureka Evaporator in Hubbard. However, because Hubbard, Ohio and Warren, Ohio are only fifteen miles apart, it seems unlikely that both Hescock and Mathews were both building the Eureka Evaporator and more probably that Hescock was simply handling sales and marketing of his invention.
Seemingly at the height of his company, Hescock died November 10, 1896, at the age of 52.
I.X.L. Evaporator
Milton Mathews was the owner and operator of the Warren Evaporator Works, Warren Ohio, which, as noted above, was in operation as early 1884 where it was manufacturing the Eureka Evaporator. It is notable that letterhead from that time only includes text for “Warren Evaporator Works, Manufacturers of Hescock’s Eureka Evaporator and Sugar Camp Fixtures” and does not mention the I.X.L. Evaporator.
In December 1887 Milton Mathews, along with Henry Hill of Chester Crossroads, Ohio (later from Chardon, Ohio) applied for a patent for their design of an evaporator with a unique hinge or pivot along one side of the boiling pans. The patent was awarded in 1888 (patent no US382314) and was marketed as the I.X.L. Evaporator. It featured flat pans that hinged on a piece of pipe or tubing that served as an external connector between each pair of pans, like the u-shaped siphons used to connect other evaporator designs. The hinge was built on either the left or the right side of the pans and appeared like a bulge to the wall of the pans. Each pan also featured a drain hole on the high side that was plugged with a metal stopper with a long metal handle.
Milton Mathews was born in 1842 in Trumbull Co. Ohio and like Hescock, served in the Civil War in Ohio’s 19th Infantry from September 1861 to October 1862, before being discharged with a disability. Mathews’ partner on the patent, Henry Ezra Hill, is someone we know much less about. Born in 1849 in Geauga County, Ohio, Hill was said to have invented an evaporator in the Chardon area in the mid-1880s, but it is unclear if this was with Mathews or independently. Census data tells us Hill was a merchant and salesman in the 1890s and early 1900s, but it is not clear who he worked for or with, perhaps the Warren Evaporator Works. Hill appears to have retired by 1919 before passing away in Warren, Ohio in 1925.
I.X.L. was a fairly common product name at the time, sort of like Acme and was not a specific acronym for anything. Rather it was a play on the words “I Excel” proclaiming the high quality and performance capabilities of the product. Early drawings and advertisements emphasized the ease with which the pans could be raised on their hinged connections and that it did not require an engineer to operate.
Interestingly, before 1897 the advertising images of the evaporators show a flat bottom to the back pan. Images after that date all show the vertical tubular flues on the raised back pan. I.X.L. Evaporator sales literature gave buyers a choice between a flat back pan or their unique “preheater” which featured an array of round tubular flues on the back pan that extended vertically into the arch.
Considering Hescock died in 1896 and it was at about that time that the I.X.L. Evaporator began to be made with the tubular vertical flues, it is very possible that Milton Mathews’ idea for the vertical tubular flues was sparked by seeing the horizontal tubular flues on the 1893 Hescock patent, a design of which he was most certainly aware.
Although it never appeared in the images of the I.X.L. advertisements and sales brochures, all the known examples and photographs of I.X.L. Evaporators show a round, sunburst pattern vent on each of the cast iron doors. I.X.L. Evaporators are also notable for the one-piece casting of the iron door frames on their arch front and their very squared, vertical wall design on their arches.
Mathews’ Warren Evaporator Works was located on the east side of Warren, Ohio on Woodland Avenue between a branch of the Mahoning River and the Ashtabula, Youngstown, and Pittsburgh Railroad. The Warren Evaporator Works continued to manufacture and sell I.X.L. Evaporators into the 19-teens. Around 1918 it appears that the plant was closed, and Milton Mathews retired from evaporator fabrication. Mathews died in Trumbull County a few years later in 1925.
