All Bartholf machines licensed under Howe's patent carry the Howe name and patent date. They are sometimes mistakenly referred to as Howe machines, but they are no more Howe machines than those manufactured by Wheeler & Wilson, Singer, or many others. On April 6, 1858, Bartholf was granted a patent for an improvement of the shuttle carrier. He continued to manufacture sewing machines under the name "Bartholf Sewing Machine Co." until about 1865. Using serial numbers, Bartholf machines can be dated approximately as follows: _Serial Number_ _Year_ 1-20 1850 21-50 1851 51-100 1852 101-235 1853 236-290 1854 291-321 1855 322-356 1856 357-387 1857 388-590 1858 591-1337 1859 No record of the number of machines produced by Bartholf after 1859 is available. The Bartholf machine illustrated bears the serial number 128 and the inscription "A. Bartholf Manfr., NY--Patented Sept. 1846 E. Howe, Jr." This machine is in the collection of the Baltimore County Historical Society. Note the close similarity between it and the 1850 Blodgett & Lerow machine manufactured by Bartholf.

The Bartlett machine was first manufactured in 1866 under the January 31, 1865, and October 10, 1865, patents of Joseph W. Bartlett. The machines were made by Goodspeed & Wyman for the Bartlett Co. and were so marked. The inventor received another patent on April 7, 1868, and later machines carry this third date also. Although the first few hundred machines did not bear the dates of patents held by the "Combination," before the end of the first year of production Bartlett was paying royalties. He continued to manufacture sewing machines until the early seventies when he converted to the manufacturing of street lamps. Using serial numbers, Bartlett's machines can be dated approximately as follows: 1-1000, 1866; 1001-3126, 1867; 3127-?, 1868. There is no record of serial numbers for the succeeding years.

Bartram, notably his patent of January 1, 1867. Three machines were exhibited at The Eleventh Exhibition of the Massachusetts Charitable Mechanics Association in 1869 where they were awarded a bronze medal. They were compared favorably to the Willcox & Gibbs machine (see fig. 39), which they resembled. Bartram received additional patents in the early seventies and also manufactured lockstitch machines. Using serial numbers, machines may be approximately dated as follows: 1-2958, 1867; 2959-3958, 1868; 3959-4958, 1869; 4959-5958, 1870; 5959-6962, 1871; 6963-7961, 1872; 7962-8961, 1873; and 8962-9211, 1874.
