COWBOY #7972 Patcher Sewing Machine

Patcher style leather sewing machines are found in every shoe repair shop in countries around the World. They are used to repair stitching and tears in shoe and boot uppers. These machines are unique in that they are fed entirely by the presser foot, which revolves in a full 360º circle. The COWBOY #7972 leather patcher(www.cowboysew.com/product1.htm) is capable of sewing up to 5/16" of light to medium temper leather, with up to #138 bonded nylon or polyester thread. It has a narrow cylinder arm of either 12 or 18 inches in length; making it ideal for sewing boots, round cases, bags, purses and hats. Patchers are extremely useful for sewing decorative patches onto garments, like leather vests. The bobbins and bobbin cases are very small, compared to a standard industrial sewing machine. They hold a lot less thread and are best suited to thinner grades of bonded nylon, such as #46, #69, or #92. This machine features a lube pot on top, and a Barney knob on the hand wheel. The hand wheel and bobbin winder can be moved from the back to the front of the machine.
Every new #7972 purchase comes complete with a gear reduction servo motor, mounted on an adjustable height pedestal work stand, with locking ball bearing castors. And belt safety cover is standard supplied as per CE regulation. Also included are four bobbins and one pack of 10 needles (to match your preferred thread size). The COWBOY #7972 has single, top feed, with teeth on the bottom of the foot. There is no feed dog on the bottom; just a smooth, double-ended plate with a small needle hole at one end and a larger needle hole at the other end. It is best suited for sewing non-markable chrome tanned/garment leather projects, or those where the tooth marks are not objectionable. The maximum clearance under the lifting presser foot is 3/8 inch, which allows you to actually sew about between 1/4" to 5/16" maximum. Also, the stitch length varies a bit with the thickness being sewn. Shoe patchers, like the COWBOY #7972 series, although typically used with #69 thread or smaller, can sew with up to #138 bonded nylon, or 3 cord cotton/linen thread. If you plan on using this size thread, we advise you to purchase the "large" bobbin (option "B") machine, in the arm length you prefer. Above shoe patching machine can replace Singer 29K class and Adler 30. If you needle a little extra room when sewing, you can consider COWBOY #7973 long arm shoe repairing machine. If you need to sew material that is considerably thicker than 5/16 inch, and/or with thread heavier than #138, you may want to consider buying our bottom feed, heavy duty COWBOY #7105 capable of sewing almost 1/2" with #346 thread. Or, consider one of our super heavy duty triple feed machines, with a smooth feed dog and high lift walking feet. These "harness stitcher" - heavy leather sewing machines are available in 3 arm lengths: the12.5" arm COWBOY #7205 or the 16.5" COWBOY #7441, or the 25" arm COWBOY #7441-25. All three of these large stitchers are capable of sewing up to 7/8 inches of leather, with a size 415 thread handling capacity.
