COMBING MACHINE Filed Jan. 26, 1942 In van/oz:-
a Patented Nov. 28, 1944 2,363,546 COMBING MACHINE John William Nasmith Heaton Mersey,
Manchester, England Application January 26, 1942, Serial No. InGreat Britain March 7, 1941 3 Claims. (Cl. 19-121) :1 The present inventiontrelates to combingmachines for textile fibres, of the Nasmithtype, and
in which machines the top comb moves to and from the detachingroller position, descending to. penetrate the fibretuft being dealt with and again lifting from such tuft, and disengaging there- I from.
I have found it in practice desirable to ensure that the top comb should not entirelydisengage from the fibre tuft until the separation of the latter is entirely made in the operation ofthe machine, and the object of this invention is to provide means for ensuring that the top comb shall remain engaged in the fibre tuft until theseparation of the latter is completely ended before such comb lifts. For this purpose the invention comprises in combination with an oscillated top combbearing arma member which permits the fall of such arm to penetrate the tuft and effects its lift on its retrogressive movement from the usual detaching rollers, with means for varying the point.
at which, on such retrogressive movement, the
4 having left the incline 9 continues its forward course along the face 5 of the lever 6, and-during this time this latter lever is slightly withdrawn by the operation of the shaft L,so that when the I bowl 4 in its return movement arrives at the point where it left the inclinefl thelatter is no longer otherwise do, this ensuring the complete separalift is effected. As in the second model of Nasmith combing machine one top comb operating shaft serves to oscillate the topcombs machine heads.
The invention, with suitable and practical details of these arrangements, will now be described with reference to the annexed drawing, which is a section through a machine head. 1
Referring to the drawing, W indicates the nipperj shaft; D, d the detaching rollers, T the top comb shaft oscillated in the manner known for f the operation of a top comb shaft independently of the machine nipper in the secondmodel'of Nasmith combing machine, and L a further shaft in a plurality of L in that original position. The bowl must therefore move a little further before coming into con tact with the incline-and lifting. Thus the top comb remains down a little longer than it would tion of the detached tuft before lifting of the comb. In this way the point of penetration is rendered quite independent of the point when the top comb lifts, and
I claim:
may be varied either way.

The top comb arm I is pivoted on a pin 2 oscillating along an arc If! and fixed in the lever 3 keyed on the shaft T. The arm carries a bowl 4 which rests on the upper surface Bof a second arm 6 pivoted at l in the lever 8 keyed on theshaft L. On the 3 arm 6 is an adjustable incline 9,1af1d it also car,-
ries a broad-headed set screw H .resting (ma bowl l2 running on a pin l3 fixed in the framing. a .The parts are so arranged {and designed that I when the top face 5 of the arm 6 is horizontal arm and a, co-acting partupon thelotherarm with. consequent fall at aconstant pointand lift -,\of the top comb'bearing arm in its oscillation, and
means for-altering the position at which the con-I trol arm lifts the top combibearing arm at each stroke of the machine in relation to the point of r previous fall of thetop cqmbbearing arm. I
the top comb is practically at the proper depth and in proper relation to the detaching roller D. The set screw ll serves to correctany slight inaccuracy. At that point in the stroke ofthe ma 1 chine when the combshould penetrate the nipper tuft, the arm 6 is stationary, and the inclines 9 in all the heads of the machine are adjusted just to touch the bowls 4. All havingbeen adjusted they may all bemoved simultaneously alittle one I and an oscillated shaft connected'to thecontrol w h arm, with consequent variation of position of the r inclined face borne by the control membertatieach complete stroke of the machine between the point way or the otherto vary the moment of penetration. This provides a convenient and; powerful means of altering thelamount of waste,quite independently of the nipper adjustment. The bowl 3.
