USPTO = U.S. Patent Office . Images of the actual patent can be viewed on the U.S. Patent Office web site but a special TIFF viewer must be installed with your browser in order properly work. More information on how to configure your computer to view these patents can be found at TIFF image Viewers for Patent Images.
DATAMP = Directory of American Tool And Machinery Patents . A sister site to VintageMachinery.org with information on patents related to machinery and tools. A much easier user interface than the USPTO's for finding information on machinery patents.

Patent Number Date Title Name City Description
5,339 Nov. 02, 1875 Improvements on rotary bed planing machines John Ballantine ON, Canada The invention is for a method of "coupling the bed slats together". This patent was extended as patent 11,493.
    Improvements on rotary bed planing machines Daniel Cameron ON, Canada  
174,944 Mar. 21, 1876 Improvement in planing-machines Adam Cant ON, Canada Equivalent to Canada patent 4,530. The patented machine is a rotary-bed planer. The patent covers the design of the bed-slats and the driving-wheels for the bed.
The 1897 Cowan & Co. catalog has a "12 in. patent revolving bed moulder" bearing this patent date. Although Cowan Co. was a rival to Cant, Gourlay & Co., this patent is the only remotely likely candidate matching the patent date (there were several Canadian patent issued on the same date but no other patent from that date is applicable to a moulder).
5,951 Apr. 10, 1876 Rotary bed moulding machine John Ballantine ON, Canada According to information in patent 11,493, this patent was assigned to Thomas Cowan on 1879-01-08, and then on 1880-03-29 he did "assign an interest..." and at that point the page ends and there is no next page. This patent date is seen in a ca. 1890 Cowan & Co. catalog on their "10 in. Patent Revolving Bed Moulder". This patent was extended as patent 11,494.

11,493 Jul. 15, 1880 Improvements in wood planing machines John Ballantine ON, Canada This is an extension of patent 5,339 for an additional five-year term.
    Improvements in wood planing machines Thomas Cowan ON, Canada  
    Improvements in wood planing machines Daniel Cameron ON, Canada  
11,494 Jul. 15, 1880 Improvements in rotary bed planers John Ballantine ON, Canada This is an extension of patent 5,957 for an additional five-year term.

12,420 Feb. 26, 1881 Spring guard adjusters for moulding machines John Ballantine ON, Canada Patent covers a mechanism that adjusts the two guards on a moulding machine either simultaneously or independently. This patent date is seen in a ca. 1890 Cowan & Co. catalog, e.g., on their 10-inch moulder.

47,257 Oct. 12, 1894 Feed-water purifier Henry Esson Moffat ON, Canada An undated (but circa 1895 to 1900) woodworking machinery catalog from Cowan & Co. mentions that they are "the sole manufacturers of the Moffat Patent Feed Water Heater and Purifier."
49,432 Jul. 09, 1895 Matching head for planing machines Isidore Emanual Eby ON, Canada The inventor was a machinist.
"...the object of the invention is, first, to provide a simple and rapid means whereby what is known as the 'Richardson' cutter may be attached to and readily detached from the matching heads and the ends of spindles, and, secondly, to provide an extremely simple means of fastening the cutters on the matching head..."
This cutter head is seen in a ca. 1900 catalog from Cowan & Co., where it is described as "The Cowan Patent Matching Heads, with the Richardson Patent Cutters". The Richardson cutter patent is 60,787.
59,691 Apr. 12, 1898 Saw-setting machine William Clark ON, Canada See also US patent 615,964. This saw set is featured in an addition to the 1897 catalog from Cowan & Co.
615,964 Dec. 13, 1898 Saw-setting machine William Clark ON, Canada See also Canada patent 59,691.
117,354 Mar. 23, 1909 Speed mechanism for planing and moulding machines James Baird ON, Canada The inventor is described as a draughtsman. This mechanism allows the planer feed rolls for momentary variations in relative speed in order to accommodate the rollers moving as lumber thickness varies, as when feeding different-thickness boards front-to-back through the planer. According to the 1909-07-15 issue of Canada Lumberman and Woodworker, "Mr. Baird has sold the Canadian rights in the invention to Messrs. Cowan & Company of Galt, who are now applying it to their line of moulders..."
