ALBERT BACHER, OF NEW YORK, N. Y.
YARN HEATER AND srnamnn.
Application filed February 5, 1924. Serial No. 690,793..
This invention relates to yarn heaters and steamers, and generally to apparatus for steaming and heating by steam any filamentous material served to knitting or weaving B machinery of whatsoever character.
The object of this invention is the production of a contrivance for guiding and heating the yarn led to knitting machines, and particularly spring needle knitting nachines, in such a manner as to prevent the yarn from becoming damp or wet. and to provide means whereby any water of condensation that may run down the casing or yarn will drain ofl' promptly at the low- .15 est point ofthe apparatus. The present invention is an improvement upon the like apparatus set out in my Letters Patent of the United States numbered 1,522,092, dated January 6, 1925, and it is intended for the same purpose, that is to say, to do away with the usual oiling or any other'treatment of the yarn toprevent breaking, such as blowing dry steam upon the yarn before it goes to the needles.
The present invention comprises partsof special construction and arrangement as illustrated in the accompanying drawings, of which Fig. 1 is a side View of one form and drain in vertical section. Fig. 2 is a side view of'a different form or modification, the body, guides, and internal steam tube being shown in vertical section with respect to the body or casing. Fig. 3 is a vertical section on the broken line 33 of Fig. 2. Fig. 4 is an end view of all parts assembled taken from the right side of the whole as shown in Fig. 2.
Throughout the drawings and description, the same letter is used to refer to the Same part. 1
Considering Fig. 1, A is a vertical heater tube, provided with end connections such as the connection a at the upper end. There is a steam inlet B controlled by the valve 6. At the lowest end of the tube A is the drain connection C, which has a drain pipe D and a trap (Z, for discharging the water of condensation. The yarn guides are marked E and e, and are placed in the end connections of the vertical tube A. It will be noted that the draining devices are connected at the lowest point of the tube A.
For many usersthe modified form illustrated in the remaining fi ures of the drawings is chosen as most esirable and ser= viceable. The body or casing F has a diamond-shaped cross-section, and. it will be noted that the interior walls incline vertically downward. so that any water condensed thereon will run down to the lowest point of the casing into the drain f and drain trap f.-
.he steam inlet G is connected with an internal steam tube g, lying within the casing. or body F, and the inner end of the tube 9 is usually positioned and supported upon an internal shoulder or socketg' of the casing end. It will be observed that the material which is found in practice to best answer the purpose in this invention, and
"it will be noted that throughout the draw- .of this invention showing the heater tube ings the yarn guides are ofthe same form and construction. Each has a body portion of relatively greater diameter, usually threaded to engage'corresponding threads in the openings of the casing, and a shout or nose K, of decreasing diameter. body and snout are provided with a passage in the customary manner for the guidance of the yarn is. 4
The operation of this invention may now be understood from the drawings and the foregoing explanation. As the yarn passes through the casing, it is subjected to the heat of the steam, and it can not accumulate an excess of moisture for the reason that the steam is dry, and any water of condensation on the interior of the casing descends rapidly to the drain. The snouts or smaller ends of the guides project inside the casing towards each other, and no water can collect upon them and thus reach the yarn. Furthermore, the internal steam tube 9 is provided with the drain perforations k, and only dry steam passes through the steam perforations H to the passing yarn.
Having. now described this invention, and explained the mode of its operation, what I claim is-:'
1. In a yarn heater and steamer, a casing having its vertical middle section constructed in diamond shape and its ends vertical, removable yarn guides engaging the said ends and projecting into the casing, a perforated steam pipe passing into the casing below the said yarn guides, and a drain pipe connected with the lower portion of the diamond shaped section of the casing, the lower walls of the said casing sloping downwardly towards the said drain pipe.
2. In a yarn heater and steamer, a yarn heating and steaming casing having a diamond-shaped cross-section the walls of which on the inside incline vertically downward, the said casing having openings arranged opposite each other on substantially a horizontal line and located-at the widest part of the said casing, yarn guides placed in the said openings and provided with body portions and snout portions, the said snout portions being projected within the casing and extending towards each other, the said guides having passages for yarn extending which on the inside extend vertically through the said body and snout portions, and draining devices connected with the lower portion of the said casing.
3. In a yarn heater and steamer, a yarn heating and steaming casing the Walls of downward, the said casing having openings arranged opposite each other on substantially a horizontal line, yarn guides occupying the said openings and provided with body 'portions and snout portions, the said snout portions projecting within the casing towards each other, the said guides having passages for yarn extending through the said body and snout portions, the said casing having a steam inlet tube therein provided with steam perforations along the top side of the tube and draining perforations arranged along the lower side of the said tube, and draining devices connected with the lower portion of the said casing.
In testimony whereof I afiix my signature.
