\ SPINNING SPINDLE' Filed Au 22, 1934 INVENTOR W BY ATTORNEYS I is 2,024,584 srnwmc SPINDLE Gompei Kuwada, Maedani-m Kawabe-gum- Japan Application August 22, 1934, Serial No. 740,937 i In Japan December 7, 1933- i 5 Claims. (01. 2415-4611) My invention relates to a spinning spindle with the object ofholding the bobbln to. the spindle more tightly than by mere surface contact between them, of causing this grip to be tighter 5 at higher speeds and in construction such that each integralpart may be separately removable for facile replacement; 7 V The reference is to be had to the accompanying drawing in which, I

10 Fig.; I is an. elevation of the spindle,

.F'igQII is a front elevation of the spring, Fig. 111 is a side elevation of thesame, n Fig. IV is a horizontal section of the same, and Fig. V is a perspective view'of the top of the spindle wharve showing the circumferential and 7 vertical grooves into which the springs are positloned. r

In this drawing I is the spindle wharve, 2 is the spring, 3 is the saddle to the

spring

2, 4 is the cap to the wharve enclosing the springs, 2 in place, 5 is the opening to the cap through which saddles 3 may protrude. In above drawing the same notation indicates the same part.

' As shown by Fig. Ithe wharve of thespindle is madein two parts, the inner part being grooved circularly at the top and vertically alongits side in several places, and the outer part made to cap over the inner part. i i

Figs.II, III and'IV show the construction of the springs that are placed in the abovementioned grooves. These springs bear on their backs the saddles 3 which are metal pieces clasped over the said springs, the exterior of which is well rounded over. The caplis so constructed that it fits-tightly over the wharve and over the upper bar of the springs and moreover is provided with openings to admit the spring saddlesto protrude beyond the exterior surface oi the wharve cap.

As to the working of the spindle, when a bobbin 40 is placed over the spindle thelight' resilience of the springs 2 presses the saddles 3 against the inside ofthe bobbin to ensure bobbin at the start to revolve alongwiththe spindle, and as the speed increases the centrifugal force set up bythe weight of the saddle causes the saddle to press more tightly against the inside of the bobbin; thus further ensuring the grip between the bobbin and thespindle. r

In caseany integral part ofthe spring or of 60 the saddle becomes injured or worn by use, it may be easily-replaced on removalofth'e cap 4. I 1

Heretofore there have been spindleswith only springs to assist in gripping thebobbin to the spindle but in such the edges of the'springs rub- 66 p ns against inside of the. bobbin tends to'cause ing the action of the free pieces,

In myinvention the springs are to provide the 10 means of holding the bobbin lightly enough for its insertion and removal and for fixing the bobbin to its spindle so that the bobbin may revolve with the spindle from the very start when the latter is set revolving, a very essential 5 point to be assured in spinning of yarn.

Having thus described the principle of the invention what I claim is:-- a

1. In aspinning machine spindle, a wharve comprising an inner member grooved circumfergo entially at its top and vertically along its side and an outer cap member fitting overthe inner memher, at least one T-shaped spring having its horizontalbar and its vertical bar positioned in the circumferential and'vertical' grooves 'of the 25 .inner member by the'cap member, but having its vertical barfree to move within groove of the inner member. 2. In a spinning machine spindle, a wharve the vertical comprising an inner member grooved circumfer- 3o entially at its top and vertically along its side and an outer cap member fitting over the inner member, a plurality of T-shaped springs having upper horizontal bars and vertical curved bars, said horizontal bars and said verticalbars be- 35 ing positioned respectively in the circumferential and vertical groovesyof said inner. member, the horizontal bars of said springs being held against [the circumferential groove of the inner member Ventially andvertically along its side and an outer cap member fitting over the inner member, at least one T-shaped spring having its horizontal bar and its vertical bar positioned, respectively,

in the circumferential and vertical grooves of the inner member by the 'cap member, said spring 66 comprising vertical groove of the inner member, and metal saddle pieces secured to the vertical bar of said spring.

5. In a spinning mac e spindle, a wharve anmnerimem r grooved circumferentially and .v g and, an outer cap member fitting over the i'rir'ier member, a plurality of ,T-shaped springs having {their horizontal bars and their vertical bars positioned in the circumiere'ntiai and vertical grooves respectively oi 9,024,5s4 I a said inner member. said springs having their horizontal bars held against the circumferential groove of the inner member by the cap member but-having their vertical bars tree to move within the vertical groove of the inner member, metal saddle pieces clasped over the vertical bars of the springs andthe cap'member being provided with apertures into which the saddle pieces on the vertical bars may'protrude.
