COMBING MACHINE.

Application filed March 21, 1923. Serial No. 626,661.

To all whom it may concern:

Be it known that I, JOHN IVILLIAM NA- SMITH, of I-Ieaton-Mersey, Manchester England, have invented certain new and useful Improvements in Combing Machines, of which the following is a specification.

In my United States Patent No. 1,369,532 there is described and shown a combing machine with a top comb that can be removed bodily from the machine for cleaning and repairs and it is so arranged that it can not be drawn away until the needles of the comb have been raised up quite clear of the leather covered detaching rollers. But ithas been found that, although in removing the comb the needles could not easily touch the roller yet an inattentive operative in re placing the comb could, if careless, let the needles touch the roller to the detriment of both,and one object of the present invention is to provide means to prevent this. It has been further found to be unnecessary to remove the comb entirely from the machine merely to clean it and a further object is therefore to provide a convenient rest for the comb to support it whilst the operative removes any fibres or seed which may get fixed in the comb. This rest and the above mentioned preventive means are conveniently combined but might if desired be separate. Reference to the appended drawing along with the description will make the invention clear.

In the said drawings, Figure 1 shows the mechanism in vertical longitudinal section; Figure 2 is a similar view of the mechanism at one point during the removal of the comb; and Figure 3 shows part of the cradle which rocks the top comb.

The cradle T which rocks the top comb is pivoted freely on the shaft T and rocked to and fro by the oscillating shaft W through the connecting rod T and the swivel T hinging on the stud T fixed in the lower end of the cradle. The lower end of T is formed with a slot T and the forward member of the slot is prolonged as an arm T terminating in anotch T. The upper face of the arm is conveniently made as an arc of a circle with center at T. Fig. 3 shows the lower end of the cradle. The arm T forming the forward side of the slot T is united to the leg of the cradle T by the bridge I) Fig. 3 cast together with them. The top comb arm T also swings on the center T when in working position and is adjustable in the vertical direction by the set screw In the lower end it carries a pin T which engages in the slot T and when the comb is in working position with the screw T resting on the shaft T the stud T is in the lower end of the slot T as shown in Fig. 1. It is therefore obvious that, before the comb can be drawn forward the pin T must be lifted clear of the top of the slot T, when the needles of the comb T are quite clear of the roller (Z. But the tail T is not yet quite clear of the shaft T (Fig. 2) but rests against it whilst the pin T is drawn forward along the arm and into the notch T where it rests suspended in a convenient position for clearing the needles, the needles travelling along the dotted path 2) to the dotted position shown in Fig. 1. On pushing the comb back out of the notch its own weight suiiices to cause it to slide back and drop automatically into its working position, the needles again following the path 39 until they are clear of the back of the roller (Z before it can drop to its place.

Obviously other means of guidance and support might be devised without departing from the spirit of the invention.

Claims:

1. In a combing machine a top comb rocking on an independent center, means for rocking the said comb and means whereby the comb is guided well clear of the detaching rollers both when it is lifted and when it is drawn forward, the said latter means being such as to prevent replacement of the comb in working position unless it be held well clear of the detaching rollers.

2. In a combing machine, a top comb resting on an independent centre, means for rocking the said comb, means for lifting and drawing the comb forward clear of the detaching rollers, and a support on which the comb may rest when so drawn forward.

3. In a combing machine a top comb rocking on an independent centre. means for rocking the said comb and means formed on the said rocking means to guide the comb well clear of the detaching rollers during removal and replacement.

4. In a combing machine a top comb rocking on an independent center, means for rocking the said comb, means formed on the rocking means to guide the comb well clear of the detaching rollers during removal and replacement and means formed on the said guiding means to support the comb in a conmeans being such that when the comb is'released from the supporting means it falls automatically into Working position. 10

In testimony whereof I have affixed my signature.

venientip osition for cleaning and-clear of the detaching rollers.

5. In a combing machine a top comb rocking on an independent center, means for rocking the said comb, means for guiding and supporting the comb in position vfor cleaning, the said guiding and supporting J. WV. NASMITH.
