Description
Febn 9 P. J. THOMAS THREAD SPREADER FOR DOUBLING MACHINES Filed Jan.
lllll @mamada ers` for Doubling y of easy repairin ?atented Feb., 5, i924,
intatto Para nr cranica 'To all whom t may concern.'
Be it known that l, PACIFIC J. THOMAS, a citizen of the United States, residin at Pittston, in the county of Luzerne and Sgtate of Pennsylvania, have invented certa-in new and useful improvements in rllhread S read- Machines, of which t e tollowing is a specification.
My invention relates particularly to thread-spreading mechanisms employed in lconnection with doubling and twistin machines, and my object is to provide simple and improved means adapted to positively maintain delinite spreading of the thread convolutions upon a driven roll and permit of any break in .the threads passing t erefrom to the twisting spindle.
connection with the accompanying drawing and is clearly claims.
Fig. 1 is an elevation of my improved device, showing a portion of the spreader roll in section; Vsuch known cooperating mecha nism as will enable a clear explanation of defined in the subjoined the invention being indicated.
Fig. 2 is an end view. Fi 3 illustrates the use ofthe threadguar arm.
lin the roll-carryingl frame 5 is mounted a horizontal shaft 6 upon which is fixed asmooth-surfaced cylindrical take-up I and, on its oppositely extending portion, a bevel gear 8. This gear is normally in mesh with a bevel gear 9 on a xedly mounted vertical drive shaft l0, but is automatically thrown out of mesh in known manner by any breakage of thread. f This is accomplished, as 1ndicated, by pivotally mounting the trame post 12 in the boss 13 of a suitably fixed supporting arm 14, so that it Imay be turned upon the latter against the action of a spring 15, to disengage the roll gear 8 from the drivin shaft gear 9; the disengaging movement ein effected by Contact of a cam 16 on stop shat 17 with an arm 18 of the frame post 12, whenever-there is abreak in one of the threads 20 running through the common guide eye 21 to take-up roll 7. A stop mechanism such as is thus briefly referredto has been commonly employed, and the arrangement of known cooperating machine parts need not be further set forthas my invention relaties entirely to the speclal The invention is fully described in b the reduced roller portions 29 without ll SPRER FOR-JDOUJBLJING MACHENES.
Application led January' 31, 1922. Serial No. 532,970.
thread-spreading means provided in connection with the described construction.
llnterposed between the common guide eye 2l and the roll 7, is a spreader roller 25 loosely mounted upon a horizontal axle'or stud 26 fixed to the frame '5. This roller, which is parallel with the roll 7 and of approximately the same length, is formed'with a series of separate circular grooves 28, 28, 28, each V-shaped, and of a depth greater than the diameter of the reduced central portions 29 of the roller as shown, and the successive convolutions of thread bear upon these reduced portions 29 in passin over the roll 7 and roller 25' as indicated. lie walls of each of these deep grooves diverge outwardly so that the thread convolutions may e rea ily entered and made to bear u on s ack and in positively spaced and safely retained relation.
Y pon the projecting outer end of the fixed roller axle or stud 26 is iixedly secured a thread-guard arm 30, seated against a shoulder 31 on the aXle by a nut 32, and extending radially beyond the outer diameter of the roller so that its end portion 33 will be adapted to retain in they grooves of the roller a thread that is passed outwardly under it, as indicated bythe dotted line 20a in Fig. 3; the purpose and e'ect of this device being tol enable the operator to quickly and satisfactorily repair a broken thread while safely retaining the convolutions of thread in tautly spaced relation upon the roll `7 and grooved spreader roller 25.
What l claim is:
1. ln a thread-spreading mechanism, the combination with a fixed thread-guide, a smooth-surfaced cylindrical roll, and driving means for said roll arranged to be automatically thrown out of operation by the breakage of a thread; of an interposed roller cooperatively mounted parallel with said smooth' surfaced roll to positively spread successive convolutions of thread upon the latter, said interposed roller being provided with grooves whereby the diameter at the base of said grooves is greatly reduced relative to the diameter of said smooth-surfaced roll.
2. ln a thread-spreadin mechanism, the combination with a fixe thread-guide, a
smooth-surfaced cylindrical roll, and driv- 6 shaped which said roller lis loosely mounted parallel y ing means for said roll arrangedjzo be automatically throw out of operation by the breakage of a thread; of an interposed spreadm roller having a, series of deep V- circular grooves, a fixed axle upon Vwith said driven roll to positively spread guard arm fixed -to the projecto axle be- 10 yond the roller substantially as set forth.
In testimony whereof I allix my signature.
r PACIFIC J. THOMAS.
