Prior to Baldwin's departure from Simmons in 1913, there were many design and appearance changes made during the early years (1910-1913) of the Baldwin pinchwaist lamps. A major focus of Baldwin's design approach was to maintain a "steady even flame at all times whether the miner is standing still or swinging a pick." Included with this approach was the concern of the lamp's flame going out during times of increased pressure and air currents due to blasting and other sources. To address this problem, Baldwin filed a patent for a perforated reflector as an improvement to the cup-shaped reflector commonly found on pinchwaist lamps. The patent was granted to Baldwin on July 1, 1913 as patent #1,066,241. As claimed by Baldwin, the perforations in the base of the reflector would allow the escape of air collected by the reflector when the lamp was moving rapidly or was exposed to a strong wind so that the flame's luminosity was not diminished.

Shortly thereafter, lamps featuring the distinctive inverted conical hour-glass shape that distinguishes Baldwin cap lamps were produced by Simmons. These lamps feature patent dates of 1900 and 1906 stamped in raised letters on the top of many of these lamps but neither applies to the visual shape of the lamp. The Aug. 28, 1900 patent #656,874 by Baldwin applies to fourteen acetylene gas generation features while Baldwin's May 22, 1906 patent #821,580 applied to internal mechanical details. During the next few years the Baldwin/Simmons lamps would enjoy enormous popularity in both the metal mines and the coal mines. The company even boasted in 1913 that 80% of the carbide lamps in use are Baldwin lamps. Baldwin and Simmons continued to produce and market a growing number of cap and superintendent's-style lamp varieties for miners. For whatever reason, Baldwin and Simmons parted in 1913, Baldwin to pursue the Zar lamp development noted elsewhere in the cap lamp photos and Simmons to continue to market both Baldwin and Simmons-branded lamps. The Simmons Co. manufactured its own cap and superintendent lamps such as the classy-looking Simmons No. 38 hand lamp shown here and marked with the distinctive raised S in a diamond trade mark. Of note is the Pioneer lamp that was heavily advertised by Simmons around 1917. The patent dates marked on these lamps are for patent #688,926 awarded to A. L. Buffington on Dec. 17, 1901 for an acetylene bicycle lamp with burner and reflector on the same axis and design patent #13,542 awarded to Baldwin on Mar. 11, 1913 for an acetylene generating lamp. There is no evidence that any of these lamps were actually stamped with the Pioneer name. These lamps were among the last lamps marketed by Simmons as the company merged with the Dewar Co. in the 1919-20 timeframe.

The Universal Lamp Company was organized in 1913 by Jacob S. Sherman to produce his Auto-Lite carbide lamps. Sherman first lamp patent was filed in 1914 and awarded as #1,167,942 on Jan. 11, 1916 that would identify the pronounced crown top and concave, urn-shaped design of all Auto-Lite lamp tops for the length of manufacture. By 1918, Sherman had moved the company from Staunton, IL to Chicago. The company continued to expand its product line and in 1932, it purchased the Shanklin Manufacturing Co. and its Springfield, IL plant. An integration of the Auto-Lite and Guy's Dropper lamp design features soon followed. Universal continued to manufacture carbide lamps at the Springfield plant until 1960 when the carbide lamp products were discontinued. The company moved to Murfreesboro, TN and is now known as the Park-Sherman Co. During the 1913-1960 span of Auto-Lite's cap lamp life, the company produced at least six top design styles, four bottom styles, six cap mounting hooks, three water valve variations, three different water doors, two gas tube variations, at least nine top markings, and at least seven different bottom markings. That's a lot of combinations for a cap lamp that maintained its distinctive looks over those 47 years. Although they produced mainly cap lamps, Universal did manufacture an 8-hour hand lamp marked Big Boy as shown here in combinations of brass and steel and with two different bail designs. Originally manufactured in the early 1930s after Universal purchased the Shanklin Mfg. Co., these hand lamps were initially marked Guy's Dropper on top. Eventually the name was changed to Big Boy, but advertising as late as 1958 continued to refer to these lamps as Guy's Dropper Big Boy superintendents' lamps. The Springfield plant of Universal Lamp Co. has claimed that it produced over 9,000,000 carbide lamps during its operations!

(The Shanklin Manufacturing Co. of Springfield, IL was a prominent producer of miner's carbide lamps with its famous "Guy's Dropper" carbide cap lamp. Designed by Frank Guy, he obtained his first patent in 1910 (#974,054 of Oct. 25, 1910) and two additional patents (#1,097,716 of May 26, 1914 and #1,198,537 of Sept. 19, 1916) while developing a business arrangement with brothers George and Edgar Shanklin to manufacture the lamps. In 1913, the brothers formed the Shanklin Manufacturing Co. to mass produce the Guy's Dropper lamp. The war years of 1917-18 substantially increased the demand for carbide lamps as the need for coal and minerals peaked. The Guy's Dropper benefited with this demand with increased production of both the cap and hand lamps. In addition, Shanklin manufactured a Guy's Dropper cap and superintendent-style hand lamp variation known as the "Squarelite," distinguished by the square shape of the lamp top as shown elsewhere in my lamp pics. The Squarelite design was patented by George Shanklin on Oct. 17, 1916 as #49,782. These lamps are scarce and coveted by collectors. As with other carbide lamp manufacturers, the 1920s brought a decline in the demand for acetylene lamps and problems for the Shanklin company.

With Frederick J. Becker as president, Justrite would become the most prolific manufacturer of carbide lamps for underground use and a name synonymous with the carbide lamp. In 1911, Becker realized the potential market for carbide mining lamps and supplies and along with his chief designer August L. "Augie" Hansen, they created a product name with one of the top reputations in carbide lamps. The first lamps manufactured and advertised by Justrite in their first known advertisements of 1912 were the No. 99 horizontal, wire feed brass cap lamp priced at one dollar with nickel plating at a dollar and a quarter, the No. 100 superintendent's lamp priced at a dollar and a half with nickel plating extra, and the rare No. 77 stick lamp priced at two dollars and 50 cents. Justrite continued to expand the product line and their facilities and by 1919, they employed 350 employess and manufactured 42 distinct types of carbide lamps. Justrite's March 1919 Catalog introduced a cast aluminum 5-hour "Jumbo" hand lamp that used the Lever Feed and showed a swivel-hooked bail with a pointed mounting stick thrust through holes on each side of the bail yoke.

The production of Liberty Feed lamps was short lived and they were no longer being advertised by 1922 pretty much corresponding to the departure of noted Justrite designer Augie Hansen in 1920 and his replacement with William Frisbie. The model No. 100 superintendent-style lamp was first offered with a Liberty Feed valve in Justrite Catalogue No. 3 issued in May 1919. It was only offered in nickel plate. Justrite Catalogue No. 4 issued in December 1923 offers the No. 100 lamp with a wire feed and only in nickel plate. The brass version of this lamp is thought to be very rare. Justrite also introduced a new ribbed reinforced bottom in this same timeframe. This resulted in two rare base markings on these bottoms, one marked with a Justrite scroll banner and the other with a big J in Justrite stamping. The lamp shown here has the big J Justrite marking. The Justrite scroll banner marking is shown on the bottom of a rubber gasket water door cap lamp model No. 907 in my carbide cap lamp pics.
