This injector is designed to start itself automatically when supplied with steam and connected to the water supply and to restart automatically if for any reason the jet should be temporarily interrupted. The peculiar feature of the injector is the forcing tube, which is provided with two successive overflows formed in it by a series of laterally opening holes which have a definite areal relation to the smallest cross-sectional area of the combining tube and which are in addition to the usual large overflow between the combining tube and the forcing tube.

On one side this brass rule has an unnumbered scale of chords and architect's scales for making drawings at proportions of 1/5", 1/4", 1/3", 1/2", and 1" to the foot. The other side has 8" plotting scales with diagonal scales at each end. One plotting scale is divided to 1" and numbered by ones from 1 to 8, and the other is divided to 1/2" and numbered by ones from 1 to 16. A badly worn leather sleeve may not be original to the instrument. Compare to 1980.0676.01.
The Smithsonian's Division of Ethnology received this rule in 1951 and believed it to be of American manufacture.
At the core of any fire company is the apparatus used to fight fires and protect lives. This was particularly true of for the volunteer fire fighters in 19th century America. Often purchased with their own funds, their fire engines were the focus of their pride and affection, as well as their identities as fire fighters. Engine plates, often made of brass, would be prominently affixed to engines and inscribed with the company name, number, and founding date. Engine plates could pass from old engine to new, or be kept in the firehouse as a memorial to a departed apparatus.
This number “6” is cut from a tin and has a brass wash. It has seven holes that allowed for attachment. This number plate is believed to be from the "Big Six" engine of the Americus Fire Company No. 6 of New York City.
The traditional American leather firefighter’s helmet with its distinctive long rear brim, frontpiece, and crest adornment was first developed around 1821-1836 in New York City. Henry T. Gratacap, a New York City luggage maker by trade, is often credited as the developer of this style of fire helmet. Gratacap created a specially treated leather helmet with a segmented “comb” design that led to unparalleled durability and strength. The elongated rear brim (also known as a duckbill or beavertail) and frontpiece were 19th century innovations that remain the most identifiable feature of firefighter’s helmets. The body of the helmet was primarily designed to deflect falling debris, the rear brim prevented water from running down firefighters’ backs, and their sturdy crowns could aid, if necessary, in breaking windows.
This leather fire helmet was dates to the early 20th century. The helmet was originally painted black, but paint has flaked off of the helmet. A scrolling pattern is stamped around the brim of the hat. A metal eagle’s head frontpiece holder is mounted on to the helmet’s crown, which holds a black stippled leather frontpiece. The frontpiece has a white “1” and hook and ladder in the center, with red banners above and below with white lettering that reads “ROBERT W CHANLER/RED HOOK”. The Robert W. Chanler Ladder Company was located in Red Hook, New York. The Chanler Family was very influential in the Red Hook area, owning the Rokeby estate in the hamlet of Barrytown. Robert Chanler served several years as a county sheriff and New York State Assemblyman in the early 20th century, while also making a name for himself as a painter.

This leather fire helmet was made by Henry T. Gratacap of New York, New York in the mid- 19th century. The helmet is painted black overall with the four combs painted gold, thin gold triangles in the crown’s sections, and a red painted underbrim. A rosette pattern is embossed around the helmet’s brim, with the date “1819” painted in gold on the rear brim. Gratacap’s maker’s mark is stamped between the 8 and 1 if the date. A leather eagle serves as a frontpiece holder emerging from the crown of the helmet. The black leather frontpiece reads “READING HOSE/1/INStd/JULY 4th/1819.” The Reading Hose Company No. 1 of Reading, Pennsylvania was founded on July 4th, 1819 for the purpose of purchasing hose since the town had only bucket companies at the time.
The frontpiece (also known as shield or badge) of firefighting helmets has been a distinctive part of the American firefighter’s helmet since it was developed by Henry Gratacap in the early 19th century. These frontpieces displayed a variety of information. The fire company's name and number appeared, often alongside the city or town where it was based. The frontpiece could also include the owner's initials and rank. Most fire helmets had leather frontpieces, but frontpieces could also be made of metal, especially on presentation helmets or those worn in parades.
This black leather frontpiece was made in the 19th century. The frontpiece has three red banners with raised white lettering that reads “LAFAYETTE/STEAMER/JTV” and a large white number “14” in the center of the frontpiece. The letters “JTV” likely referred to the owner’s initials.
