This invention relates to apparatus which are adapted for measuring the lengths of yarn or cordage while configured as a multi-looped or wound skein. More particularly, this invention relates to such apparatus which are further adapted for dispensing the yarn or cordage from the wound skein.
Rotatable yarn swifts are known to be capable of receiving and supporting a skein of yarn, string, cordage, or light rope. (References below to yarn should be considered as being broadly representative to all such materials.) In many circumstances, it is desirable to accurately estimate the length of yarn which has been wound into such skein. However, conventional yarn swifts typically are incapable of measuring the length of yarn within a skein which has been received upon the yarn swift.
The instant inventive skein measuring and dispensing tool solves or ameliorates such defects and deficiencies by providing a specialized base and spindles combination incorporating special adaptations which allow the tool to perform functions of measuring the length of a skein of yarn received upon the tool, and progressively dispensing the yarn from the skein.
A first structural component of the instant inventive skein measuring and dispensing tool comprises an oblongated base, preferably having a substantially flat bottom or lower surface. In a suitable embodiment, the oblongated base may comprise a length of wood, or may be suitably alternatively composed of other materials such as plastic or metal.
In a preferred embodiment of the instant inventive tool, the oblongated base component has left and right ends, and has a mid-line or midpoint between such ends at which an axle channel component is presented. Such axle channel component preferably passes completely through the base from its upper side to its lower side.
Further structural components of the instant inventive tool comprise left and right travel slots which extend into the oblongated base. In a preferred embodiment, the left and right travel slots respectively extend leftwardly and rightwardly from the central axle channel and respectively toward the base's left and right ends. Each of the left and right travel slots preferably opens both upwardly at the upper side of the oblongated base and downwardly at its lower side, such axle channel configurations advantageously allowing vertically extending spindle mounting bolts or screws to pass vertically therethrough and to travel leftwardly and rightwardly therealong. The left and right travel channel components may suitably alternatively extend into and open at side walls of the base, such alternative channels similarly extending leftwardly and rightwardly therealong from the base's centrally positioned axle channel.
Further structural components of the instant inventive skein measuring and dispensing tool comprise left and right spindles which extend upwardly from the base and are slidably mounted thereon for selective movements along and positioning upon the base. In a preferred embodiment, the spindles are conical to facilitate smooth dispensation of yarn. The spindles' sliding movements along the base are preferably guided by and are limited by the left and right travel slots.
Further structural components of the instant inventive tool comprise left and right series of graduations, each graduation among said series being fixedly attached to and displayed upon the oblongated base. The graduations in combination with numeric indicia placed in series adjacent to the graduations function as and constitute yarn length indicia. In the preferred embodiment, the left series graduations are arrayed upon a side wall of the oblongated base, such graduation array extending leftwardly from the axle channel. The tool's right series of graduations component is preferably oppositely arrayed rightwardly along said side wall. In the preferred embodiment of the instant invention, the left and right series of graduations components substantially identically mirror each other with respect to the central axle channel, such mirroring characteristic allowing both small and large skeins of yarn received by the tool to remain substantially centrally positioned upon the tool during measuring.
Further structural components of the instant inventive tool comprise left and right pointers which are respectively connected to or displayed upon the left and right spindles, such pointers constituting measurement indicia which necessarily move with the spindles in relation to the base and the graduation arrays. In a preferred embodiment, the left and right pointers are positioned for, upon the movements of the left and right spindles along the left and right travel slots, successively aligning with graduations among the left and right series of graduations. Centimeter or inches indicia are preferably adjacently arrayed along the graduation arrays so that, upon placement of a skein of yarn about the spindles, and upon sliding movements of the spindles away from each other within the skein of yarn, the pointers may point to inch or centimeter indicia and thereby signify the length of each loop of yarn within the skein.
In a preferred mode of operation of the instant inventive tool, that the spindles and their pointers are mirroringly moved away from each other within a skein to be measured, such motions being guided by the base's travel slots. Such mirroring movements of the spindles advantageously radially balances the positions of the spindles along the length of the oblongated base. Such radial balancing of the spindles advantageously allows the oblongated base and the spindles to rotate about the axle channel in a balanced fashion. The tool's facilitation of balanced rotation advantageously allows the tool to dispense the yarn from the skein in a balanced rotating fashion.
The sliding motions of the tool's spindles along the base's travel slots are preferably facilitated by provisions of left and right slide plates, each slide plate overlying the upper surface of the oblongated plate and respectively underlie base or lower ends of the left and right spindles. During the movements of the spindles along the travel slots, the slide plates preferably move with the spindles with lower surfaces of the plates slidably contacting the base. In a preferred embodiment, the left and right pointers are respectively formed integrally with and extend from side edges of the left and right slide plates.
Further structural components of the instant inventive skein measuring and dispensing tool comprise left and right screw and threaded socket combinations. In the preferred embodiment, said combinations' threaded sockets are internally helically threaded, and open downwardly from the lower ends of the spindles, such sockets being respectively embedded within base or lower ends of the left and right spindles. The screw components of such combinations preferably respectively extend upwardly through the left and right travel slots to threadedly engage the helically threaded sockets. Loosening or unscrewing of such screw and threaded socket combinations allow the spindles and their slide plates to freely slidably move along the length of the oblongated base. Opposite screw tightening of such combinations advantageously fixes the spindles at selected balanced and mirroring locations along the length of the oblongated base. Fixed and mirrored positioning of the spindles with respect to the central axle channel facilities performance of the tool's balanced rotating yarn dispensation function.
In a preferred embodiment, second left and second right series of graduation indicia are displayed upon the opposite side of the oblongated base, such additional indicia beneficially allowing, for example, one of set of graduated indicia to signify yarn lengths in inches, and allowing the second oppositely arrayed indicia to signify the yarn lengths in centimeters.
Accordingly, objects of the instant invention include the provision of a skein measuring and dispensing tool which incorporates structures as described above, and which arranges those structures in relation to each other in the manners described above, for the achievement and performance of beneficial functions, as described above.
Other and further objects, benefits, and advantages of the instant invention will become known to those skilled in the art upon review of the Detailed Description which follows, and upon review of the appended drawings.
Referring now to the drawings, and in particular to Drawing
Left and right travel slots 4 and 6 preferably extend vertically through the oblongated base 2, said slots respectively extending along the base 2 leftwardly and rightwardly from the axle channel 46. As can be best seen in
Left and right spindles 22 and 18 are preferably slidably mounted at the upper surface of the oblongated base 2. As indicated in
Left and right series of graduations 14 and 12 are preferably fixedly attached to or are displayed upon a side wall of the oblongated base 2, such graduations being mirroringly arrayed and with respect to each other so that each array radially extends along the oblongated base from the central axle channel 46. Mirroring inches indicia are suitably adjacently displayed in relation to the graduations 14 and 12, such indicia facilitating measurement of variously sized skeins of yarn received upon the tool 1. Left and right pointers 26 and 28 are preferably fixedly attached to or mechanically connected for motion with the spindles 22 and 18, such pointers progressively indicating inch indicia as the spindles 22 and 28 mirroringly move away from each other along the travel slots 4 and 6.
Referring simultaneously to
Similarly with the positioning of the right slide plate 20 beneath the right spindle 18, a left slide plate 24 is mirroringly positioned beneath the left spindle 22. The left slide plate is preferably configured substantially identically with the right slide plate 20, the left slide plate similarly having “C” channel forming flanges 23 and 25, and having oppositely positioned pointers 26 and 27. Such pointers 26 and 27 variably align with and point to mirroring first and second arrays of graduations or measurement indicia 14 and 11 scribed or printed upon the lateral and oppositely lateral sides of the left end of the base 2.
Referring to
To facilitate smooth rotating yarn dispensing motion of the tool 1, the central aperture within the base 2 is preferably enlarged to present a bearing mounting aperture 16 which nestingly receives a rotary bearing assembly. Such assembly suitably comprises a fixed radially outer sleeve 42 which rotatably receives and retains a radially inner rotating sleeve 44. Ball bearings (not depicted within views) captured within races between sleeves 42 and 44 facilitate smooth rotating movement. Where such rotary bearing assembly is provided, the central bore 46 of the assembly comprises the tool's central axle channel component.

Thereafter, as indicated by
Thereafter, the user may observe the positions of pointers 26 and 28 with respect to graduation arrays 14 and 12. In the depicted example, the user may observe that such pointers extend toward and substantially overlie the mirroring 36 inches indicia. Thereafter (or preliminarily), the user may count the looped turns of the yarn within the skein 50. For example, upon counting 40 looped turns of yarn within the skein 50, the operator may simply multiply 40 by the pointer designated 36 inches, the product indicating that the length of yarn within the skein 50 is 1,440 inches or 120 feet. Referring further simultaneously to
To allow the inventive tool to perform the above described yarn skein measuring function, the lateral and oppositely lateral graduations 12, 14 and 11, 15 and their respective adjacent inch and centimeter indicia are preferably arrayed along the base's side walls at increments which are directly proportional to actual measured distances between the spindles 18 and 22 and their outer circumferences. Such measured proportionality of the graduation arrays allows each of the pointers 26, 28, 27, 30 to designate the length of a single loop of yarn about the spindles.
Following such calculated measurement of the length of yarn within skein 50 in either inches or centimeters, the operator may add to or subtract from the yarn within the skein as needed. Thereafter, the operator may re-tighten, for example, screws 36 to fix the spindles 18 and 20 at their mirroring and centrally balanced positions upon the base 2. The centrally mirroring spindles 18 and 22, travel slots 6 and 4, and graduation arrays 12, 14 and 11, 15 advantageously assure that, upon completion of performance of the tool's skein measuring function, the skein 50 is substantially centrally positioned upon the tool's base 2. Such positioning facilitates balanced rotary dispensation of the yarn, as described below.
