OFF] C E 5'Claims. 1. This. invention relates. to a, heated. cabinet adapted to be disposed adjacent the magazine of a boxtloom and into which a pin board. contain.-v
ing. bobbins of. left twist yarn are adapted tobe placed; said cabinet having a hinged. door. meme. her on top of which is. adaptedtobe supported a second pin board: filled, with bobbins of right twist yarn. The interior of, the housing is provided with heating means such as an electric bulb. or an electric heating coil for heating the interior of the box say from twentyto fifty degrees Fahrenheit higher than, the; room. temperature to thus set the twistin the left twist yarn disposed within the housing;
In the weaving of fabrics, itis customary to have pattern means controllingthe number of picks; in which a, right twist yarn is used and; for controlling. the, numberof picks in which a left twist yarn isused. The number of picks of each. of the yarns iscontrolled by the pattern control means and varies, in. different mills.
Howevenit has been foundthat the left twist tofore, been accomplished by subjecting both yarns to the humidified atmosphere of the mill.
Some, of the; objects, of the invention having been stated, other objects will appear as. the.
description proceeds, when taken in connection. with, the. accompanying drawings, in which Figure 1 is, an isometric view of the housing showing the door in opened position;
Figure12 is an elevation of the. housing; Figure, is a vertical sectional view taken along. the. line 3.3.i n Figure 2;
Figure 4 is av schematic plan, view showing the disposition of the. housing relative to the, 100th with which it is associated. 1
Referring, more specifically to the drawings,,.
the numeral It indicates; a suitable pedestal the. left twist yarn prior to its being; transferred into the magazine oi a loom, the left twist yarn is, set and acted-uponbythe heat and thus a very muchv better quality of cloth is produced with a great decrease in the amount ofdefects in the cloth, due to the heating of the left twist yarn prior to its being used in the loom.
Also, in! some instances it is preferable; where a-combination: yarn, such as a yarn twisted; from nylon and rayon, or a mixture of nylon, rayon and cotton, that the quality of the yarn is greatly improved if it is housed within a; heated housing immediately prior to being; fed into the magazine of the loom. By providingaheated; Cabinet dis-- posed adjacent'the magazine of; the loom, this, improves the quality of cloth which can be pros dnced by heating the yarn immediately prior to its being placed into the magazine of the loom.
By placing a left twist yarn or a yarn composed of strands, of cotton and nylon or cotton and rayon or nylon, rayon and cotton, and the like, in this heated cabinet, the set in the twist is accomplished by heating the same immediately prior to its being placed in the magazine of the loom and by providing a heated cabinet with easily accessible means for withdrawing the yarn from the cabinet and having this means adjacent the loom is very desirable in that much better cloth is produced with less defects than has hereadapted tobe'placed on the floor of a mill having looms therein and risingtherefrom is a hollow pipe I I which has welded to! its upper end a hori zontally disposed angle bar l2. Welded to this; angle bar member 12 are two short angle bars l3,
and I4, and also welded to and abutting against the angle bars [3 and I4 and to the anglev bar l2 are angle bars l5 and [6 which project upwardly and rearwardly.
Welded to the short angle, iron members. I 3 and M are upright angle bars 20 and 2|, and: welded between the ends of the angle bars [5 and I6, respectively, and the upper ends of angle bars I 20 and 2 I, respectively, are. angle bars 22 and 23.
A sheet metal bottom 24 is secured to the upper surfaces of the horizontal portions of angle bars l5 and Hi. The upper ends of the angle bars 21) and, 2| have adjacent thereto an angle bar 26. Hingedly secured to the rear end of the bottom member 24 as at 21 is a back cover member 28 having a handle 29. There is also welded. between the upper surfaces of, the angle bars 22 and 23 a plate 30, against the lowerv edge of which the hinged cover 28 is adapted to fit. A strap iron member 3| extends between the angle bars 22 and 23, being welded to the proximate" edges of the angle bars 22 and 23 and against the lower surface of plate 30 This hinged cover 28 has side angle bars 32 one of which is not shown,
joined together at their upper ends by a strap iron member 34, Secured to the rearmost upper surface of bottom member 24 are angle bars 36 ea P- a in a plur li of Pi s 3. adapted o v hold a plurality of bobbins or quills to be deposited into the magazine of the loom.
Disposed between the angle bars l5, 2!] and 22 is a side'member S-I and disposed between and secured to the ang e bars l6, 2| and 23 is a side member S2. Suitable brackets such as 42 are secured to the inner surfaces of the upright angle bars and 2| and to angle bars 22 and 23.
The side wallsS-J and S-12 have suitable openings 43 and 44, respectively, therein which are covered by suitable housings 45 and 56 each having a bulb socket 41 therein which has mounted therein a suitable heating element such as an incandescent bulb 50. Leading from these sockets 47 are wires 52 and 53 which pass down along the lower portion of the compartment and pass through an opening in the bottom thereof and down on the inside of the pipe l 2 where they are joined together as at :55 and pass outwardly through a suitable opening in the pedestal l G and have a pug-in socket 56 thereon adapted to be pl g ed into a suitable source of electrical energy.
Hingedly connected as at to the main housing is a cover member C comprising an upright angle bar 63 and angle bars 64 and are welded thereto which are welded together at their outer ends and a suitable sheet metal covering 5? is secured to these angle bars 63, 64 and 55 to form oneside of the cover C. This covering 61 has ,a suitable transparent window Wl therein so that the interior of the cabinet may be viewed without opening the door member. Secured to the upright angle bar 63 is an angle bar It, the other end of angle bar Ill having secured thereto an angle bar 12 and an ang e bar 73 is secured to the lower end of the angle bar 12. Secured to the angle bars 12 and I3 is a side member 14 of 1 sheet metal which has a latch l5 thereon adapted tohook over a pin 16 projecting from the side wall S-l to hold the cover member in closedposition. The angle bar 13 has secured thereto a suitable handle H, whereby the cover member canbe moved from open to closed position and sheet metal member 853 are angle bars and 81,
serving as a guide and support for a second pin board P--2. Secured near the point 8| on the sheet metal member 89 is an angle bar 9!! adapted to serve as a stop for the pin board P-2 to support the same and a Z angle cli 91 is dsposed near the top of the sheet metal member 80 and beneath which the upper end of the pin board P2 is ada ted to be secured.
"A suitable bracket, such as 93, is secured to the front ange bar 63 and to the horizontal upper angle bar 1!] for lending rigidity to the frame of the cover portion.
The cabinet together with its stand is adapted to be placed in a mill substantially in the posi tion shown in Figure 4 where there is schematically shown a loom 95 having magazines 9% and 9? into which the bobbins are adapted to be placed from the above described mechanism. In Figure 4 the cabinet as a whole is indicated in outline with only a few reference characters applied for identification purposes.
lt is. thus seenthat one of these cabinets-can be placed in association with each loom and" the 4 yarn having the left twist therein can be housed within the cabinet and heated to the required amount, depending upon the size and wattage of the light bulbs placed therein, to exclude the 5 humidified atmosphere, which is present in the tion being hingedly connected to the main porn mill, from yarn which is housed within the heated cabinet and thus the two yarns when used in the loom will have substantially the same characteristics and overcome the difliculties above enumerated.
In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are empfoyed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being defined in the claims. a
