ca. PERRON SPOOL HOLDER FOR BRAIDING MACHINE SPINDLES Original Filed June 50, 1922 Patented Dec. 7, 1926.
UNETEE PAT GUSTAVE PEER/ON, OF PARIS, FRANCE.
SPOOL HOLDER FOR BRAIDING-MACHINE SPINDLES.
Original application filed June 30, 1922, Serial No. 571,922, and in France July 5, 1921. Divided and this application filed November 24, 1923.
The present invention relates to a spool holder for braiding machine spindle in which the spool is laid horizontally, this application being a division of my application Serial No. 571922, filed June 30, 1922.
Said spool holder is essentially characterized by the fact that the bracket acts as a support for two levers capable of oscillating in a vertical plane, one of said levers acting as tension lever for the thread and the other as looking pawl for the spool, said levers being such that, after the locking pawl of the spool has left a certain amount or length of thread to unwind, the tension lever, under the pull of the thread, swings and comes nearer the locking pawl and an arm of the bracket on which is formed the starting eyelet of the thread, so that the eyelets formed on the two levers above referred to and the eyelet on the bracket are substantially in straight line.
The tension lever is submitted to the action of an adjustable tension spring, but it is arranged in such a manner that the said spring acts on said lever through a lever arm which decreases as the tension of the spring increases.
The locking pawl of the spool is formed by a lever of the first kind always tending to be held in the locking position under the action of tension exerted on the thread by the tension lever; through its lower arm, it acts on lateral teeth of the spool flange; through its upper arm, it receives from the tension lever the necessary impulse for unlocking, at a point as far as possible from its pivot, so that the said impulse requires a strain as weak as possible.
On the annexed drawing given by way of example:
Figs. 1 and 2 show in face elevation the spool holder object of the present invention; 1
Fig. 3 is a side elevation;
Fig. 4 shows the locking pawl in perspective. v
The spool holder comprises a bracket 23 secured on the shuttle 12 of the spindle foot 11 by means of'two screws which eventually are also holding a guide plate 13 when the spindle comprises a part of this kind.
On the said bracket, is secured a'pin 24 on which is placed the spool 2.8. This spool Serial N0. 676,813.
is held in place by a spring blade 25 which can swing at 26 in a vertical plane at right angles to the spindle 24. The said spring rests on a shoulder 27 provided at the end of the pin 24 so that the spool 28 is held between the bracket 23 and the spring 25 with out however the latter being able to rub against the disc 29 of the spool.
To the bracket 23, is pivoted at 30 a stretching or tension lever 31 the shape of which can vary according to the-kind of raw material to be used, and which acts on the thread owing to the helical spring 32 secured at 33 to said lever and at 34 to the bracket.
The mounting of lever 31, spring 32 and pivot 33 is such that, when the spring is not stretched, the line 30, 33 is substantially at rightangles to the axis of spring 32 so that as the lever 31 swings and comes nearer the center of the spindle, the acting line of the spring 32 comes nearer the pivot 30 (Figs. 1 and 2).
The hooking to the bracket 23 of the end 34 of the said spring could be effected at one of the different orifices 34 provided on the projection 35 of the bracket 23. The lever 31 is guided in its movements by the walls of a groove 23 of the bracket 23.
A locking pawl 36 shown in perspective in Fig. 4 is also pivoted at 37 to the bracket 23.
This pawl is controlled by the action of a spring 38 secured, on the one hand, to the pawl at 39, and hooked, on the other hand, into one of the orifices 40 of the projection 41 of the bracket 23.
This locking pawl has an extension or tail 42 which engages in notches 43 provided in the flange 44 of the spool 28 which is a metal spool.
The locking pawl 36 forms a lever of the first kind the pivot of which is formed by the spindle 37. The amount of angular movement which is necessary for producing the unlocking of the spool being very reduced, owing to the fact that the notches 43 provided in the flange 44 of the spool are very shallow, it is possible to locate the im pulse of the tension lever 31 at a point very near to theupper end of the pawl .36. By
these means the necessary driving action happens to be very weak and does not: tend passing through their eyelets and through the --eyelet of said am into positions such that all of the eyelets are in substantial alignment, said tension lever being provided.
- near its upper end with a projection adapted the arms are in said positions, and spring means adapted to move said locking lever into locking engagement and the tension lever away from the locking lever when tension on the thread is relieved.
In testimony whereof I aflix my signature.
GUSTAVE PERRON.
