HENRY J. MARX, 0F I-IOLYOKE, MASSACHUSETTS, ASSIGNOR TO THE AMERICAN' THREAD COMPANY, OFJERSEY CITY, NEWJERSEY, A CORPORATION OF NEW JERSEY.
DRUM-WINDER.
Specification of Letters Patent. Patented Dec. 25, 191% Application filed April 4, 1917. Serial No. 159,600.
then release it so that it will turn easily and permit the thread to be pulled off as desired for the purpose of tying together the broken ends. It is an improvement on the device shown in application of H. J. Marx, Serial No. 72,003, filed January 14, 1916 (Patent No. 1,222,962), in which the brake when once applied stays in holding position so as to interfere with the unwinding of any thread.
The following is a description of my invention, reference being had to the accompanying drawings, in which 1.
Figure 1 is a front view of an embodiment of my invention.
Fig. 2 is a side elevation of the same;
Fig. 3 is a front view of a portion of the brake member and cooperating part at one stage in the operation, and
Fig. 4 is a similar view with the parts as in another stage of their operation.
In Figs. 1, 3 and 4 the face plate is omitted to show the interior mechanism.
Referring more particularly to the drawings, 1 is a drum of a drum winder, 2 is a yoke holding a bobbin 3. 4 is a frame pivoted to a support 5 at 6 and pivoted to the yoke 2 at 7 8 is a trip box movably mounted on the forward end of the frame 4 having trip-pins 9 which when released are engaged by the revolving striker 10 (Fig. 2) so as to throw the box with its projection 11 counterclockwise (Fig. 2) and release a lever 12 pivoted to the frame 5 at 13 and connected to the yoke 2 by a slot surrounding the end of the pivot 7. hen the lever 12 is released the yoke 2 falls down with the bobbin 3, which is then held away from the drum 1 by the separting shoe 14:, all as described in said application. In order to stop the rotation of the bobbin a braking member is provided consisting ofa body portion 15 and brake shoes 16. This member has holes fitting over guiding-pins 17 carried by the yoke 2. The holes in the brake member contain springs 18 to counterbalance its weight and hold it out of rigid engagement with the yoke 2. The frame member is provided with'a downivardly extending projection 19 which, as
the yoke 2 falls upon the release of the lever 12, engages a stationary anvil20 so as to prevent the brake member from moving downwardly with the yoke and make'it engage the'. descending bobbin. The construction and action thus far described, with the exception of the counterbalancing springs, is the old construction and operation of said application. I
In order to release the spool afterthe brake which stops it has been applied, I have in my present invention provided means for bringing about a disengagement of the braking member and bobbin after an interval of engagement. In the embodiment shown this consists in making the de pending projection 19 movable relatively to the body of the brake member, forming in said body guiding surfaces 21, 21, the latter being, atits upper part, shallower than the former so as to form a vertical slot for a pawl 22 about to be described, and of full width at its lower end 21 To the upper end of the movable member 19 I pivot a pawl 22, which normally tends to be moved by gravity to the position shown in Fig. 1.
In that position it lies beneath a spring-con trolled abutment 23 pivoted at 24: and held in depressed position by a spring 25 against a stop 26. Since the movement of the member 19 is blocked by the anvil 20 the pawl 22 is brought into engagement with the springcontrolled abutment 23, as shown in Fig. 3, so as to check its downward movement and consequently check the downward movement of the body portion of the brake member, bringing the bobbin into braking engagement with the brake shoes 16 so as to stop the bobbin. The bobbin and brake shoes continue to move down by gravity whereupon the pawl 22 moves the spring-controlled abutment 23, relatively to the body portion 15, as shown in dotted lines in Fig. 3, until the member 23 escapes by the pawl 22 whereupon the pawl 22 stays in the relative position shown in dots in Fig. 4:, while the spring controlled abutment 23 snaps back to its normal position. The brake shoes relations shown in Fig. 1, ready to act upon the breaking of another thread. Holes 28 :itI'8lfOI;SCI'IVS to-secure a face plate Which 1i1CtS;ilS:Zt cover.
As Will be evident to those skilled in the art, my invention permits of various modifioations Without departing from the .spirit wthereof orvthe scope of the appended claims.
What Iclaim is:
1. In a drum Winder a brake for a bobbin being Wound, means for Withdrawing said bobbin from the drum and applying said ,brake when .a thread becomes broken and means for subsequently releasing said brake automaticallyafter :the rotation of the bobbin has been checked.
2. In a drum Winder, the combination of a yoke for holding a spool, meansfor-withdrawing said spool from the drum when a therefrom and longitudinally movable relatively thereto, means for blocking the movement of said plunger as said-body portion and bobbin perfornnmovements inthe direc- :tlOIl in which @the projecting end of said plunger points, and means for temporarily supporting said plunger ,and body portion so I as to check the {movement of saidjbody:
portionduring the j first' part of its movement in said direction.
'5. In1a'brake-for a drum Winder theoombination of abo'dy portion having a; brakingsurfaoe adaptedto engage a bobbin,-a plunger -movable longitudinally relatively thereto, a spring restrained abutment carried by said body portion,and;a pawl-pivoted-to said plungerand adaptedto make emp y hol n gag en wit said spri gen ro l dabu m -.W;1 en1s Plunser is m ving-in. one direction r la ey thereto.
