MAGNETIC THREAD CLEANER Filed June 1, i957 ATTORNEYS Patented Dec. 21, 1937 UNITED STATES PATENT OFFICE 2,103,125 MAGNETIC THREAD CLEANER Nicholas Stoddard, Durham, N. 0. Application June 1, 1937, Serial No. 145,856
'1 Claim.
This invention relates to magnetic thread cleaners and has for an object to provide a device of this character having novel magnetically controlled means for severing the thread at the feeler blades when a knot, slub, nib, waste and the like is encountered.
A further object is to provide a device of this character which. will be formed of a few strong, simple and durable parts, which will be inexpensive to manufacture, and which will not easily get out of order.
With the above and other objects in view the invention consists of certain novel details of construction and combinations of parts hereinafter claimed, it being understood that various modifications may be resorted to within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.
In the accompanying drawing forming part of this specification,
Figure 1 is a front elevation of a magnetic thread cleaner constructed in accordance with the invention.
Figure 2 is a top plan view of the cleaner.
Figure 3 is an end elevation of the cleaner looking toward the permanent magnet.
Figure 4 is an end elevation of the thread cleaner looking toward the feeler blades.
Referring now to the drawing in which like characters of reference designate similar .parts in the various views, Ill designates a supporting plate having a pair of Porcelaln" guide eyes ll adjustably mounted thereon by screws H. The thread is drawn through these eyes as usual by the tractive effort of any suitable thread using or winding machine. 7
The lmot responsive means comprises a detector or feeler lever l3 which is pivoted intermediate its ends on a substantially rectangular frame Hi, the pivot pin I5 of the lever being disposed near one end of the frame, as best shown in Figure 2. The lever extends beyond the path of the thread through the porcelain eyes and is equipped with a pair of feeler blades 16 adapted to receive the moving thread loosely but adapted to be forced bodily from normal position by frictional contact with'an imperfection in the thread such as a knot, .slub, nib, or other enlargement and rock the lever on its pivot.
fully described and The feeler blades are attached to the lever by a 7 bolt I! having a shim thereon to space the blades at a predetermined distance apart, depending upon the size of the thread to be cleaned.
The opposite end of the lever is equipped with an armature l8 which overlies pole pieces IQ of a permanent horse shoe magnet 20 which is carried by the frame H. The pull of the magnet on the armature accelerates pivotal movement of the feeler lever l3 when an imperfection is encountered by the feeler blades to quickly actuate the thread severing mechanism which will now be described.
An angular dog 2| is pivotally mounted in the frame I4 underneath the feeler lever. The pivot pin'22 of the dog is passed through one leg of the dog that extends substantially parallel with the lever while the other leg of the dog extends perpendicular to the lever and is disposed substantially midway between the pivot of the lever and the armature as best shown in Figure 1. The dog normally hooks over a keeper plate 23 which extends across the rear end of a knife blade 24. The blade projects through a slot in one end of the frame l4 and is slidably supported inside of the frame by a pin 26. A rod 21 is secured to the plate 23 and to a downwardly bent end portion of the blade 24 and sleeved upon the rod is a helical spring 28 which is normally under compression when the dog 2| is engaged with the keeper plate 23. When the feeler blades l6 encounter an imperfection in the thread too large to pass between them, the blades willbe moved bodily and the movement of the lever will be accelerated by the attraction of the armature to the permanentmagnet.
Movement of the lever is transmitted to the dog to rock the dog from engagement with the keeper plate. Instantly the spring expands and forces the knife outwardly to sever the thread. The rod 21 projects outwardly through an end wall of the frame l4 and is equipped with a grip 29 by means of which the knife blade may be withdrawn sufficiently to permit the dog to hook over the keeper plate and maintain the knife in cocked position ready for the next operation.
From the above'description it is thought that the construction and operation of the invention will be fully understood without further explanation.
What is claimed is:
A thread cleaner comprising a support, thread guides on the support, a feeler lever pivoted on the support, feeler blades on the lever responsive to imperfections encountered in the thread to rock the lever, an armature on the opposite end of the lever, a magnet on the support adapted to attract the armature and accelerate rocking movement of the lever, a spring pressed knife slidably mounted on the support, and a dog pivoted on the support and normally holding said knife cocked, said dog being adapted to be struck and dislodged by rocking movement of the lever to free the knife for severing the thread contiguous to said imperfections.
NICHOLAS STODDARD.
