Class 42.
MACHINE No. 42-1
FOR LEATHER.
Outside Measurement of Bed, 19 x 8 1/2 inches; 10 1/2 Inches from Needle to Base of Arm.
THE machines of Class 42 are specially adapted for strong lock-stitching of heavy material by foot-power, but are equally suitable for operation by steam, electricity or other power.
The Main Driving-Shaft is provided with three bearings avoiding vibration; the shape and size of arm are such as to secure the utmost strength and stability.
The Balance Wheel is 8 1/2 inches in diameter and arranged for two rates of speed; its increased weight and momentum greatly promote ease of operation and steadiness of motion.
The Needle-Bar of machine No. 42-1 is provided with a cam, especially adapting the machine for HRAVy LEATHER StiTcHING, it is used in the manufacture of Harness, Carriage Tops, Trunks, Traveling Bags, Dog Collars, Sword and other waist Belts, and all leather work of a similar nature. It is provided with a roller-presser that holds the material constantly and firmly to the action of the drop-feed located at the left of the needle; the presser can be thrown up and away from the needle and does not mar the most highly finished surface, thus enabling the stitching of Patent Leather, etc.
The Shuttle is unusually large; it oscillates about a Central Bobbin of correspondingly increased size, having great thread capacity. This form of shuttle and its motion secure the highest efficiency in this part of the stitching process; it is unequaled for ease and speed of operation, convenience and durability. The range of stitch is up to one-half inch in length, the motion of Thread Take-up is so regulated as to uniformly obtain a perfect stitch; a larger size of thread may be used to a given size of needle than in other machines and the thread entirely fills the needle- hole. The machine uses a short needle which has a lift of one-half inch above the bed. The powerful drop-feed carries the material with a direct, positive and exact movement.

The machine has a link connection from needle bar to the cam on the main driving-shaft; the dropfeed is on both sides the needle, it works in conjunction with a yielding presser and is arranged to carry the heaviest material uniformly and steadily. This. machine is especially adapted to the stitching of Matting, Rugs, Awnings and Sails, Tarpaulins, Trunk Covers, Tents, Wagon Covers and similar work heavy textiles.
Machine No. 42-3 is provided with the Vibrating Presser which secures a uniform feed of two or more thicknesses or plies of fabric, it is also of great usefulness in sewing soft goods liable to pucker and in stitching around curved edges.
This machine is especially adapted for stitching Carpet Mitres, Coal and Ballast Bags, Feed and Flour Bags, for binding heavy textiles, etc.
The excellence of workmanship and accurate adjustment of the various. parts in each of the machines in Class 42 secure easiest operation, longest wear and least expense of repairs, while their capacity enables the stitching of either thin or thick material with the greatest facility.
Machine No. 42-4 corresponds to the preceding description, excepting that it has link needle-bar connection and is provided with long-beak cylinder shuttle, specially adapting it for Boot and Shoe manufacture.
