TARRING ROPE-YARNS.
Specification of Letters Patent No. 6,445, dated May 8, 1849.
To all whom t may concern.'
Be it known that I, IVILLIAM MONTGOM- ERY, of Roxbury, in the county of Norfolk and State of h/Iassachusetts, have invented a new and useful Improvement in the Process of Tarring Rope-Yarns; and I do hereby declare that my said invention is fully described and the machinery used therein represented in the following specification and accompanying drawings, letters, figures, and references thereof.
The process of tarring rope yarns, as heretofore practised has been to immerse or pass the rope yarns into tar either in a boiling` state or one heated nearly up to such. IVhen common American tar, or that in general use is so heated, it loses more or less of its volatile properties, spirit or essential oil, and in consequence thereof becomes hard or Rope yarns saturated in such manner, are generally so stiff and unyielding, that ropes made of them cannot be used for bolt rope, or such as is applied to the edges of sails, as such rope requires to be very pliable.
In my improved process of tarring rope yarns, I do not heat the tar to such extent as to volatilize or evaporate any material portion of its essential oil. I only heat it to blood heat or thereabouts, and I heat the rope yarns just before they are immersed in the tar and while they are so heated I either plunge them into, or pass them through the tar so as to saturate them with it to the extent required. I do not consider it absolutely essential to my process that the tar be heated at all provided it be in a sufficiently fluid state to readily enter the yarns, but as this is not always Vthe case, a slight degree of heat may be employed to good advantage.
The mechanism I have adopted or devised for heating and tarring the yarns is shown in top view in Figure 1, and in longitudinal and central section in Fig. 2. I do not however limit my invention to the use of either of the precise elements constituting such machinery, as any well known substitute or equivalent may be employed in lieu of the same. For instance the mode of heating the yarns I have adopted and exhibited in the drawings is to make use of hot rollers or hollow cylinders heated by steam let into them. Instead of such a form of the heating element of the machine, some other well known mode of heating may be substituted. So with any of the other essential portions of the machine. I do not intend to confine my invention to the use of such element in the precise form I have represented and described, as the same element in a dierent form, or some other equivalent for it may be used. v
In the said drawings A, B, C, denote three hollow drums or cylinders, arranged with respect to each other as denoted in Fig. 2, and made steam tight. They are respectively mounted on or supported by shafts or axles D, E, F, which are made tubular 1n part, or so as to receive and suffer hot steam to pass into and through them, and
into their respective cylinders or rollers, in`
any manner well understoodand practised. The said cylinders are disposed over or near a vat or cistern G, which is for the purpose of holding the tar, and is provided with a depressing reel H, a pair of squeeze rollers I, K, and a guide plate for guiding and separating the yarns, the whole being'arranged as seen in the'drawings, and made like mechanism of the same character now existing in the tarring machines in common use. The yarn in its passage between the heating cylinders, through the tar cistern, and between the squeezing rollers is represented at L. By such a machine the yarns are heated by contact with the external surfaces of the hot rollers or steam cylinders, and while so heated or while in a heated state, are passed into and through the tar within the cistern and thence between the pressure or squeeze rollers, which remove the superfluous tar from them. Yarns so tarred become very soft and pliable, and can be made up or twisted into rope which may be used to great advantage as bolt rope.
I lay no claim to the process lof tarring yarns as it is ordinarily conducted, viz, that wherein the tar is first either heated or boiled, and while so heated or boiler the yarns are passed through it, they being at their entrance into the tar at the temperature of the surrounding atmosphere; but
IVhat I do claim as by invention is- My improvement on the said process, the said improvement consisting in heating the yarns, previous to their immersion in or passage through the tar, and using the tar either at the temperature of the atmosphere In testimony whereof I have hereto set my surrounding it, or at a temperature of blood signature, this twenty sixth day of Decemheat or thereabouts, and not one which shall ber A.
