THOMAS HENRY SMITH, or JAMES'I'OWN, NEW YORK.
SPINDLE FOR BOBBINS.
Specification of Letters Patent.
Patented Aug. 28, 1917.
Application filed July 22, 1916. Serial No. 110,769.
T 0 all whom it may concern:
Be it known that I, THOMAS HENRY SMITH, a citizen of the United States, residing at the city of Jamestown, in the county of Chautauqua and State of-New York, have invented certain new and useful Improvements in Spindles for Bobbins, of which the following, taken in connection with the accompanying drawings, is a specification.
The invention relates to spindles for bobbins which have means for holding the bobbin on the spindle, and the improvement consists in providing a simple and easily constructed positive means for holding the bobbin on the spindle by means of which the rotation of the spindle causes the bobbin to turn into more firm attachment on said spindle rather than loosen therefrom, yet which permits the quick and easy placing and removal of the bobbin on and off the spindle without loss of time to the operator and the equally easy removal therefrom and which is not liable to get out of order or break and which does not wear or impair the interior surface of the bobbin; and the invention consists in the novel features and combinations hereinafter set forth and claimed.
In the drawings, Figure 1 is an elevation of the bare bobbin; and Fig. 2 is an endwise elevation of the lower end of the bobbin and showing the smooth interior surfaces of the same. Fig. 3 is an elevation of the improved spindle with a lengthwise sectional view of the bobbin showing the shape of the interior opening in the bobbin and the manner in which it fits upon the spindle. Fig. 4 is an elevation of the improved spindle.
Like characters of reference refer to cor responding parts in the several views.
The numeral 10 designates the spindle which has the usual whirl or pulley 11 attached thereon.
The spindle 10 has a solid metallic conical-shaped enlargement 12 above the pulley 11 which fits the conical-shaped interior opening 15 in the lower end of the bobbin 13. The interior walls are contracted at 14 near the upper end to fit the spindle 10 to guide and steady the upper end of the bobbin as it whirls at a speed of ten thousand revolutions per minute. The conical-shaped interior wall of the bobbin 13 at the point 15 is smooth so as to easily slip on and off the conical-shaped enlargement 12 'in the Irorecessarily rapid process of changing bob- It is found, however, that this conicalshaped enlargement l2 wears smooth from constant rubbing with the wooden bobbin and the bobbin 13 is apt to work loose and jump up and wabble because of an imperfect fit and the high speed, thereby impairing the winding of the bobbin and making waste. Accordingly, in order to hold the bobbin firmly upon the solid enlargement 12 a spiral groove 16 is cut in the periphery of the conical portion 12, which groove 16 has preferably clean edges which while they impinge on the inner wall 15 of the bobbin 13 are not sufliciently sharp to wear or impair the wall 15. The groove 16 is cut in a direction which is the opposite of the direction in which the spindle 10 is rotated, thereby causing the bobbin 13 to turn more tightly onto the spindle rather than to be loosenedtherefrom by high speed or imperfect fit and as the wall 15 wears smooth the spiral groove in the solid metal cone 12 has just sufficient hold on said wall 15 to prevent the bobbin jumping up or even loosening, yet the smooth solid cone 12 and smooth wall 15 permit the easy and rapid change of bobbins.
It is apparent that the bobbin can be manually raised directly from the grooved enlargement 12 without turning said bobbin. It should be fully borne in mind, however, that the interior wall of the bobbin is smooth and does not have any spiral thread or cut therein thereby permitting the use of the old the common form of bobbins. The spiral groove 16 in the conical enlargement 12 is simply to insure the firm placing and holding of the bobbin upon the spindle. This improvement is easily made at low cost and is positive and durable in its action. The spiral groove 16 should be cut a number of times around the cone and at a low angle very much as shown in Figs. 3 and 4 so that while the solid cone 12 wears smooth the inner wall 15 of the bobbin 13 still has the succession of grooves formed by the spiral to draw over in order to remove the same and the spiral groove 16 being at such a low angle as shown tends to turn the bobbin onto the solid cone 12 into tighter contact therewith no matter how smooth the inner wall 15, or outer surface of the cone 12 may become.
I claim as new:
In combination with a spindle, an acornlike part on said spindle having a spiral groove of low pitch formed in and extending entirely around its periphery, the convolutionsof said groove'being relatively widely separated to provide relatively wide smooth spiral faces between the convolutions of the groove, said faces being configured similar to that of the bobbin bore,
and a wood bobbin having a smooth bore which is maintained smooth by the wide 1:
In testimony whereof I have affixed my 2 signature in the presence of two witnesses.
