MILL NUT.
Application fifed November 26, 1926. Serial No. 150,940.
My invention relates to mill nuts associ* ated with the spools of spinning or twisting frames for silk, cotton, etc. In this type 01? spinning machine there are usually a great Intunber of spindles employed; each spindle requires a mill nut, and, due to the irequency with which the spools are placed upon and removed :t'rom the spindles, the mill nuts, being "formed from a relatively soft wood, are quickly Worn out and must be replaced with new ones.
in the course of operation, mill nuts are very frequently, due to their worn out condition, accidentally displaced or removed -i'rom their spindles While in operation,
thereby necessitating a great loss in time and expense.
The object of my invention therefore resides in the production of a mill nut that is formed of aluminum or any other material having a relatively hard Wearing surface. The scope of my invention extends to whatever constructions or compositions may be defined by or included within the terms or language of the appended claim.
In the drawings:
Figure 1 is aside elevation of a mill nut illustrating it in its assembled position with the spindle, bobbin and drop arm ilyel';
Figure 2 is a view in perspective ot' the mill nut, and
Figure 3 is a longitudinal sectional View thereof. 1
i is well known to those familiar with the art, the mill nut, generally designated at 1.0, has a bore 11 adapted to fit over the upper end of a Spindle 12 for the purpose of retaining the drop arm flyer 13 in position immediately above the bobbin 14. The spindles 12 are of steel and have a slightly tapered upper end for extension into the mill nut bore 11 and these mill nuts are trio 't-ionally engaged with the stem. Through rotation of the spindle, oil is caused to travel upwardly onthe stem and comesin contact the with the mill nut, with the result that the nut has a tendency to swell and burst where formed of wood. Furthermore, asthese mill nuts, unless iirmlyrengaged with the spin dle, are likely to fly off during operation,
causing disarrangeinent and a loss of time, they are generally very forcibly applied, with the result that they are very often split without this split becoming noticeable.
in accordance with my invention, I provide a mill nut formed of mo-ldable mate.- rial which, while readily soitso that" it Will not mar or damage the upper end of the spindle, is capable of taking a high polish, so that no damage will result to a worker applying or removing the same during operation of the machine. The material em ploycd must, to be eli'ective, be sufficiently dense to be non-absorbent, as otherwise it will collect the oil arising upon the spindle and become extremely diilicult to handle. lit must also be light, as otherwise the additional weight at the upper end of the spindle Would, unless the spindle Was absolutely truly centered, have a tendency to cause Whipping of the same and rapidly destroy spindle. l urthermore, during this whipping, the nut might fly from the spindle and strike and damage eitheran attendant or some of thedelicate portions of the machine; Materials having the qualh tications above noted are aluminum and the composition commonly known in the trades as bakelite and analogous substances.
l/Vhat I claim as new, and desire to secure by Letters Patent is As an articleoI" manufacture, a mill nut for use upon bobbin spindles consisting oi a moldable material relatively soft as re gards the bobbin spindle while capable'of taking a smooth tinish and suiliciently dense to be substantially non-absorbent to 011, said material having a specific gravity not materially exceeding; that oi aluminum.
