mom-nu non imi'mmme THE UNIFORMITY'OF YARN.
' Application filed September 15, 1922. I Serial No. 588,509.
' To all whom it may concern Be it known that we, ERNEST D. Wanamof Watertown, in the county of Middlesex i and State of Massachusettsg and ARTHUR H.'P ARsoNs, of Gloucester, in the county of Essex and said State, both citizens of the United States, have invented a new and.
useful Improvement in Machines for Determining the Uniformity of Yarn, of which the following is aspcification. I The purpose of our invention is to indicate variatlons in the uniformity of yarn, andjit comprises means whereby variations in the yarn will be. indicated or recorded in 15. such a manner as to be very much magnified.
Our invention will be understood by referonce-to the drawings in which it is shown in its preferred form.
I Figure 1 is a side elevation of a machine embodying our invention; I
4 Fig.2 being a plan view thereof.
. 1 is. a table having mounted thereon two uprights 2 between which is carried a bobbin 3 Wound with yarn 4. .5 is a guide eye mounted on'a bracket on the table 1. 6 is a stationary-foot mounted on a. micrometer- 61 supported from an upright by means of a strap 8. By means of the micrometer the height of the foot can be adjusted positively so and the adjustment measured. The top of this foot is 'a flat surface or table 10. Its
' support carries two eyes 9 which are in line with the guide e e 5, one on each side of the table 10 over which the yarn is drawn, so at that the yarn pl ssing from the bobbin to the ide eye 5 W1 thence-proceed in a straight Erie throu h one of the eyes 9 across the table 10, thence through the othereye 9 to a second guide eye 11 supported on thetable I 4.0 1. From the guide eye 11 the yarnpasses between a pair of feed rollers 12- and 13. By means of these rollers the yarn is drawn by the path above described from the bobbin 3. Power is applied to :the roller 12 by means of a shaft 14 on which the roller 12 is mounted, the shaft 14 being connected with a'suitable source of power.
Ontop of'the stationary foot or support- 6 rests a" movable foot 15 which is hung 5Q from a roller 16-011 theupright 7 and carrying a weighted arm '17, the sliding weight on which is usually adjusted to counterbalance the weight of the movable foot 15, or it may be adjusted to vary the ressure M of the foot on the yarn as desire This Opposite the mirror 18 is a drum 19 which I is closed light-tight except for a small opening 20. Within the drum is located a light, preferably an electric bulb 21, On a stand 22 on the table 1 is adjustably mounted a lens'23.
.It will be noted from Fig.2 that these parts are so adjusted that a beam of light from the bulb 21 will pass through the lens 23 and strike the mirror 18. From the mirror 18 it will be reflected as a point of light to a strip of paper 24 which is caused to pass around two spools 25 and 26 to present a flat surface. This paper is a sensltized paper such that the beam of light reflected upon. it by the mirror will act photographically thereon, and the result will be such an indication as is shown in Fig. 1. at 27 this wavy line indicating variations inthe thickness of the am.
' To cause the feeding of the photographic I strip I continue the shaft 14 along the table 1 providing it with bearings as at 28 and 29. At its end isa bevel gear 30 which is in mesh with a bevel ear 31 "mounted on a vertical. shaft 32 whic carries a spool 26. By this means the shaft 32 and spool 26 are turned. .34 is a presser roll which engages and directs the passage of the photographic'strip ing for the presser roll 34, the other end being attached by a spring 40 to the top of the casing 36. A similar constructienprovides a presser roll 341 for the spool 25. The spool 26 is thus a feed or. draft roll for the photo aphicstrip which is thus caused to travel cm a magazine roll (not shown) i in front of the mirror 18- and at a proper speed with relation to the speed of the yarn, it being held under tension by the presser rolls 34, 341. Any irre rising and falling of t e movable foot will be magnified very much and properly recorded on the photographic strip.
We pre er to mount the table on the stationary foot on a micrometer secured so that the level of the table may be adjusted according to the diameter of the yarns.
Our invention may be otherwise embodied, but the above is a simple and, as it has been proved, an eflicient and accurate way of determining the irregularitiesin a yarn,ir-
, regularlties which because they are minute cannot be determined except by enlargement. 7
What we claim as our invention is 1. In a machine of the kind described, a fixed member to support the moving yarn, a movable member, means for su porting said movable member above said' ed member for movement perpendicularly to the yarn supported by t e xed member, means for drawing the yarn between said members, and means operable by said movable member whereby the movements of said movable member may be indicated...
fixed member to support the moving yarn, a
' movable member, means for supporting said larities causing the 2. In a machine of the kind described, a
andmeans operable by said movable member whereby the movementsv of said movable member may be recorded.
3. In a machine of the kind described, a
fixed member to support the yarn, a movable member mounted to move with each variation in the thickness of said yarn, means for supportin said movable member above said fixed mem r for movement perpendicularly to the yarn supported by the fixed member means for drawing the yarn between sai members, and means operableby said movable member whereby the movement of said movable member may be indicated, said means comprising a mirror to be moved by said movable member to make an indication by reflection.
v 4. In a machine of the kind described, an adjustable fixed member to support the yarn,
a movable member,'means for supporting memsaid reflected beam of light whereby movements of said movable member will be in dicated.
