Reeling, Spinning, and Twisting Silk Machine Patent Model
Patent No. 1,367, issued October 12, 1839
Jacob Pratt of Sherborn, Massachusetts
Pratt is an example of an inventor who thought he had a more complicated original invention than he actually had. In his patent application file, his specification makes four claims. Out of those four, only one was approved by Charles M. Keller, the patent examiner, and that claim was for using a trough of zinc. The trough held spools of silk fibers prior to spinning and was filled with warm water, which kept the fibers from sticking together.
The Journal of the Franklin Institute, 1840, commented: “Its construction is, in general, similar to such as is well known, and is not claimed as new . . . No particular reason is given for making the troughs of zinc, and we suppose that copper would do equally well; but from the special mention of this metal we were led to look for some ground of preference to it.”
Howarth’s and Jones’s patent covered certain improvements on flyers and spindles attached to machinery (such as throstles or spinning frames) where a twisting apparatus was needed. The improvements were useful for roving and spinning cotton or other fibers.
They experienced some delay in obtaining a patent and hired R. H. Eddy of Boston, a patent attorney, to represent them. Their original claims were abridged and condensed. In the last letter (December 1, 1836) from Eddy to Commissioner of Patents Henry Ellsworth, Eddy returned the amended specification without any other essential changes in it and said “. . . leaving it to your discretion to reject or admit the claim. . . . But I supposed that the arrangement and combination of these different parts with each other might show sufficient novelty to constitute and claim to a patent.” Presumably with Eddy’s help, Howarth and Jones were able to receive their patent.
Humphries’s innovation was the addition of a supplementary layer to the bottom of a carpet to provide an extra cushion and to strengthen the overall structure. The added stuffer weft is a stout, loosely twisted cord, woven into the underside of the carpet and interlaced with the ground warp. These samples of carpeting are important because they are the earliest known examples of patented carpeting in the United States.
Whether this patent was utilized is unknown but there is evidence of Humphries being involved in the manufacture of carpeting. The Journal of the Franklin Institute lists premiums awarded at their eighth exhibition in 1833. John Humphries was presented a premium for four pieces of Brussels carpeting. The judges noted that “these goods are of excellent quality and style, and satisfactory assurances have been received that they are exclusively of American workmanship throughout all the processes from the raw material to the finished product of the loom.”
According to his patent specification, Yerkes patented “the revolving arrangement and combination of the sliding shaft, with the broach, or with the spool, for the purpose of removing and renewing the latter . . . .” The action of the sliding shaft enabled the operator to remove and change the spool when the spring was pressed down. In addition, he patented the ring in combination with the flyers that distributed the yarn on the spool. Yerkes intended his improvements to be used on machines for spinning cotton and other fibers.
This is one of a pair of pieced work pillowcases. The top has a fiber filling and is quilted, the lining is linen. Embroidered on front is "H.S. 1836".
According to information given with the donation in 1945, this quilt originally belonged to Abbie Corey Brackett. Abbie Corey [Corah] married Ichabod Brackett, a hired man on the Corey family farm in Plainfield, Conn., in 1816. “All her father, Squire Joshiah Corey would allow her to take from home, were the two quilts, which she made. He allowed her nothing more. The Coreys were Scotch.” While this may have explained the other “quilt,” a woven coverlet, this particular quilt dates from about 1825-1835.
The quilt top consists of lengths of a single glazed, roller-printed cotton. The “Pillar Print” design is in red and brown, with an olive drab color added by surface roller. The combination of architectural and floral elements was particularly popular from 1825 to 1835 in American household furnishing fabrics. The quilt has a plain-weave white cotton lining and cotton fiber filling. Concentric diamonds and a quilting pattern variously known as “Rob Peter and Pay Paul,” or “Lafayette Orange Peel” or “Dolly Madison’s Workbox,” quilted at six stitches per inch, complete the quilt.
Records indicate that Abigail Corey was born about 1789. She married Ichabod Brackett (about 1790-1862) 3 February 1816. Sadly, after his death, Abigail is listed on the 1870 census as “Nabby Brackett” born about 1787 and living in Dudley, Worcester, Mass., as a pauper. On the 1880 census she is listed as Abigail Brackett and an “inmate” in Dudley. The donor received this quilt and a woven coverlet from a friend of her mother’s, Mrs. Hattie Vinton Wright, who was the great-granddaughter of Abbie Corey Brackett. When the items arrived at the Museum in 1945, they were deemed “excellent examples representing types not duplicated in the collections.”
This experimental telegraph register was made by James Green and was reportedly used by Rev. Henry Sheib of Baltimore and Samuel Morse on private line demonstrations in the late 1830s. After talking with Joseph Henry, Morse adopted u-shaped electromagnets like the one used on this object. The large wooden pulley supported a hanging weight that pulled the paper tape under the stylus.
Telegraph registers are electrically-activated printers that receive Morse code messages. The message travels as a series of electrical pulses through a wire. The pulses energize the register’s electromagnets which move a lever-arm holding a pen or stylus. A clockwork mechanism pulls a strip of paper across the pen or stylus, recording the message. Short pulses draw or emboss a dot, slightly longer pulses a dash. The sequence of dots and dashes represent letters and numbers.
