JOHN D. SHARPLES AND THOMAS CROWE, OF TAFTVILLE, CONNECTICUT, ASSIGNORS TO OLD COLONY MACHINE COMPANY, OF NEW BEDFORD, MASSACHUSETTS, A CORPORA- TION 0F 'MASSACHUSETTS BoBBIN-s'mrrrriv'e MACHINE.
Application filed February 18, 1918.
To all whom it may concern:
Be it known that we, JOHN D. SHRrLEs and THOMAS CRown, both citizens of the United States, and residents of 'Taftville, county of New London, and State of Connecticut, have invented an Improved Bobbin-Stripping Machine, of which "the following is a specification, reference being had to the accompanying drawings, forming part thereof.
The present invention relates to an improved machine in which spent bobbins having on their shafts tail ends of roving or yarn can be mechanically fed forward to a device effective to sever the coils of said tail ends of roving or yarn without injury to the heads or shafts of the bobbins.
One of the objects of this invention is to provide a machine having a roving or yarn severing implement from which the bobbin? in its feeding movement, is always positively spaced, provision being made to bring the coils of roving or yarn to position to be severed.
Another object of the invention is to provide a novel means to guard the severing implement in order to avoid injury to the operative.
Another object of the invention is t0 provide a novel guide or guard for determining the approach of the bobbin head or shaft to the roving or yarn severing implement.
Other objects of the invention will appear fromI the following description.
The invention consists in the construction of the yarn severing implement and its guard.
The invention also consists in the fixed means for engagin the coils of roving or yarn and so separating them from the shaft of the bobbin that said coils may be subjected to the shearing cut of a suitable severing implement without possibility of injury to said bobbin. Y
The invention also consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described and pointed out in the claims.

Similar characters of reference designate corresponding parts throughout.
In carrying this invention into practice weV construct -a machine having a runway constituted bythe parallel side members 11, 11 spaced apart and suitably braced and supported at a convenient height. The bobbin carrying belt 12 extends through said runway and is mounted on the pulleys 13 and 14 of which pulley 14 is mounted on ashaft which has the belt pulley 15 driven by belt'l from thepulley 17. The bobbin carrying or feeding belt 12 has the outstanding members 18, 18 which engage and move forward bobbins placed on said belt 12 in a suitable position. Provision is made to yieldingly support a portion of the belt 12 at or about the point at which the yarn severing operation occurs by means ofthe roller 19 j ournaled on a shaft of the counterweighted arm 20 which latter is pivotally sustained between brackets 21, 21 depending from the side members 11, 1l. At la suitable point in the length of said runway is located the downwardly inclined dropper plate 22 which has members secured to said side members 11, 11. The office of this dropper plate 22 is to guide downward the bobbins passing therebeneath on said belt 12 to overcome the lifting action of roll 19 on belt 12.
Mounted on or inthe side frame members poin-t at which belt 12 is yieldingly sustained by roller 19 are the bearings 23 and 24 in which respectively the quills orsleeves 25 and 26 are secured. Quill 25 has at its inner end the disk 27 havingat its periphery the clearance 28 the lower portion of which has the inclined yarn lifting edge 29 terminating in the yarn engaging point 30 which meets the peripheral curve or guard edge 31 of said disk 27. Quill or sleeve 26 has at its inner end the bearing 32 having the stop pin 33. On this bearing 32 is rotatably received the collar 34 of the guard shell or casing36 having' the opening 37 in its peripheral wall and the counterweighted arm 38. Collar 34 has the slot 35 through which stop pin 33 extends whereby the swinging of the guard casing 36 on said bearing 3-2 is limited by the length ofsaid slot 35. Disk 27 of quill 25 may fit slightly within the peripheral wall of the guard shell or casing 36 and constitute a closure therefor.
Journaled in the bores of the quills or lsleeves25 and 26 is the cutter shaft 39 having the ,belt pulley 40 and the cutter disk or element 41 which latter is contained within the guard shell 36 and rotates approximately in contact with the disk 27. This cutter element 41 has a diameter somewhat less than the disk 27 or, at least, the curve 31 ofpoint 30 extends beyond the radius of the cutter element 41 and guards the approach to the edge of said cutter element.
On the quills or sleeves 25 and 26 are adjusted and secured the conical guard members 42, 42 which, preferably, are spaced apart a distance which will permit the passage therebetween of the head h of a bobbin shaft s without permitting said bobbin head to be'raised 'by the counterweighted roll 19 into an injurious contact with the mechanismk located between said guards 42, 42. At the same time the conical shape of these guards 42, 42 will not unduly resist the passage of the head 7L of a bobbin and, after the passage of said head 7L, will permit the bobbin shaft s, because of its small diameter, to be raised by roll 19 into contact with the curved edge 31 of the yarn engaging point 30 of member 27.
Pulley 17 is on the shaft 43 which has also the pulley 44 driven by belt 45 from the pulley 46 of the main shaft 47. This latter shaft is operated in any usual manner and has the pulley 48 which operates the belt 49 whereby the pulley 40 of cutter shaft 39 is driven. Any other suitable driving mechanism may however be substituted for that v disk 41 will be guarded somewhat thereby to prevent injury to an loperatives hand...v
When a bobbin advances y,with the belt 12 its head 7L will pass beneath the dropper plate or guide 22 and will be guided thereby downward against the resistance of `roll 19. After passing beyond the lower end 'of said dropper plate 22 the bobbin head k will be raised by roll 19 and will be received between the conical guards 42, 42 which, as stated above, will limit the upward movement of said bobbin head, such upward movement of the bobbin head will however be sufficient to enable it, in its further advancing movement, to engage weight 38 of the guard casing or shell 36 and thereby effect the swinging of said shell 36 approximately as shown in Fig. 9, and this shell 36 will be maintained substantially in such p0- sition by the shafts of the bobbin passing beneath said weight arm 38. As'the bobbin shaft rises between the conical guards 42, 42,
said shaft will contact with the curved edge 31 of member 27 adjacent the point 30 and will ride against said edge without injury to said bobbin; the point 30r will engage between the coils c, c of roving or yarn on the `bobbin and will act as a wedge to stretch or lift said coils away from the bobbin shaft whereby said coils will ride up the inclined edge 29 of said member 27 sufficiently to bring saidcoils against the severing edge of the rotary cutter disk 41 which owing to its shearing cutting action eifectually severs said coils c, c which will then drop from the shaft of the bobbin without leaving any material amount of lint or fluff.
