Journal of the Franklin Institute of the State of Pennsylvania, Vol. 6 (Classic Reprint)

Excerpt from Journal of the Franklin Institute of the State of Pennsylvania, Vol. 6: Devoted to the Mechanic Arts, Manufactures, General Science and the Recording of American and Other Patented InventionsThe question of who was the first inventor is one which we are not prepared to discuss, as it belongs to another tribunal.2. For a mode of making Woollen Roping, or Slubbing, by the "Spiral Slabbing Machine;" Austin Steele, Waterbury, New Haven county, Connecticut, April 1.The main cylinder, doffers, combs, and small rollers, in this machine, are represented exactly like those in the drawing accompanying Mr. Charles Atwood's specification, page 378; but instead of the tubes between the doffers and small rollers, the wool, as it is separated by the combs, is received upon a short revolving apron; it passes along this apron, across which "is another apron, or belt, which presses upon and revolves on the said web, and rolls, or twists it; or a roller, working obliquely, may be used for the same purpose. The effect produced by the motion of the upper apron or roller, is to twist or roll up the roping or slubbing spirally." The claim is to "the mode of making woollen roping, or slubbing, by rolling it up spirally, as above described." Mr. Atwood refers to this mode of rubbing, and objects to it, as producing a degree of felting injurious in the subsequent operations upon the slubbing, and upon the fabric manufactured from it; so far as we may be allowed to judge without experience, we are inclined to prefer Mr. Atwood's plan.3. For a machine for Thrashing all kind of Grain, called the "Paragon Thrashing Machine;" William C. Ross, Penfield, Monroe county, New York, April 1.The novelty and merit of this machine depend upon the "placing the apron on an inclination, and reducing the motion of the main, or thrashing cylinder, and consequently reducing friction, &c."The main cylinder is of wood, covered with iron, or furnished with six beaters, also covered with iron, to protect them against wearing."The improvements relied on in this machine, are, in adding to the diameter of the main cylinder, consequently producing the same effect with half the revolutions, thereby reducing the friction, which the inventor considers the most discriminating feature of its utility; in the inclination of the apron; and in the conciseness of the machine and its appendages. I therefore claim all the above improvements, together with the privilege of varying the dimensions and proportions of the improved thrashing machine, as my fancy may from time to time hereafter dictate, so that all the while I adhere strictly to my principle, and depart not from it." Which principle is the making the cylinder twice as large as one of half the diameter, and inclining the apron by which the machinery is fed.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
