Specification forming part of Letters Iaient No 47, |90, dated April 1l, 1865.

To a/ZZ whom it may concern:

Beit known thatl, OALEB S. DAVIS, of' Lancaster, in the county oi' Lancaster and State of Pennsylvania, have invented a new and useful Improvement on Flax-Spinning Machines 5 and I do hereby declare that the following is a full, clear, and exact description of the construction and operation ofthe same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l is a perspective view in part ot' a spinning-frame, showing the several positions ot' the steam or hot-water chambers I I (with their steam-pipe M) with respect to the carrying and retaining rollers. A B are the stands erected on the table c for the roving-bobbins. D is the l roller-beam beneath the carryingrollers E E, behind which are the back or holding rollers, G H, and behind both pair of rollers is the cylinder or chamber I. 0n the other side said cylinder or chamber, marked I', is placed between said two pairs of rollers. In either case there is a steam-pipe connected with said chamber, which pipe M may be extended the entire length of the chamber with perforations directly beneath the slots Y on the cylinder or chamber I; or made without such perforations when water is to be heated by said steam-pipe M. K represents the head for connecting the pipe M with a pipe, m, from the boilers; L, a valve for regulating the admission of steam or shutting it oh, N, the driving-pulleys fixed upon the axle of a cylinder, N', from which pass endless cords around the pulleys P, xed on the spindles O to drive the same; S, collar-rail for spindles; T, step for the same; It, the bobbin; Q, the iiier usually employed. f

Fig. 2 is a vertical cross-section of the same. Fig. 3 exhibits a modification of the chainber or cylinder I when hot water is used, heated by the non-perforated steam-pipe M. Fig. 4 shows another modification oi' a chamber, Lf, which may be employed when it is desirable to submit the roving to a longer ac'- tion within the steam or hot-water chamber.

The nature of my invention consists in the introduction of a cylinder or chamber, I, in close proximity to the carrying and retaining rollers Gr H and .E F. This' chamber or cylinder is traversed at its base by a steam-pif e, M. (The steam may also be admitted directly into the chamber through the head k and con I n ccting-pipe nr.) But it isprelera-ble to continue the steam-pipe M the entire length of the chamber or cylinder I for the purpose of imparting heat and-moisture tothe rovings in spinning tlax. By this means the heat and moisture so essential, if, indeed, not indispensable i'or line dax-spinning, is applied to the rovings in such a manner as to obviate the Waste or slopping of water caused by the use of open troughs, in which also the degree of heat is limitedto the power of endurance ot the hands of the operator when uniting a broken ro vin g, whereas by my means the water the direct action of steam in their passage through the cylinder or chamber I in their respective slots Y, which are directly over a perforation or perforations,z, in the steam-pipe M, from which the steam issues, a sufficient degrec of heat and moisture is imparted for flaxspinning. These slots Y in the cylinder or chamber I have a sliding cap, U, covering the top and sides, so as to leave an opening sufficient for the roving to pass smoothly through on each side at the lower edge of the cap. While this cap prevents the escape of steam above, it is readily slid aside so as to a1- low the united roving to enter by simply bringing it down into the slot and sliding the cap in place to cover the same. This cap may be made steam-tight by means of gum cloth or its equivalent.

,I also contemplate to modify my cylinder or chamber I in such a manner as to ada-pt it-for water heated by a non-perforated steam-pipe, M. Fig. 3 and the supplement to Fig.3 illustrate this modication. The slots Y are slightly enlarged, and are closed by a cylindrical pulley or disk, X, with a groove on its edge,

in which the roving lodges, and which acts both as a sinker and friction-pulley, and it should be galvanized. This disk or pulley X has its pivot on the lever W. The lever itself moves up and down on a pivot in the upright x Thus a broken roving may be united by the operator and so placed that the grooved pu` ley immerses it on closin g the slot and keeps it lunder the heated Waterin its passage through the chamber, obviatin g the use of rollers, under which the rovings are made to pass by the hands oi' the operator necessarily thrust into the water to accomplish it, besides greatly facilitating the operation. T he location of this modied chamber and steam-pipe connection is the same on the frame `as when steam alone is used tor heating and moistening the tiax rovings.

I am aware that brass and guttapercha roll-v ers have been used in connection with waterspinning vi here an open trough is used heated by means of a steam-pipe.

The great advantage ot' my invention is, rst, the application of steam in the manner specitied and the construction of the chamber used in water-spinning, so that by a slight modification heated water can be used instead of steam.

I do not broadly claim heating the water tions z opposite the slots Y Within said chamv ber, together with valve L, in combination with the connecting-pipe m, arranged and operat- VYing in the manner specified. Y Y

2. A modified chamber, I with its slots Y enlarged, in combination with the disk or pulley X, lever W, and steam-pipe M, without perforatious, constructed and operatingin the manner and for the purpose specified.

C. S. DAVIS.
