GOMBING MACHINE.

Applicationfiled September 26, 1922.

To all whom it may concern:

Be 1t known that I, JAMEs J oLLr, a British sub ect, resldlng at Deane. Bolton, county of Lancaster, England, have invented certain new and useful Improvements in Cornbing Machines, of which the following is a specification.

This invention relates to combing machines of the Heilmann=llasmith type in which an oscillating movement is imparted to the nippers and top combsto cause them to approach to and recedefrom the detaching rollers.

In the Nasmith coniber, the nip-per, the feed roller and the top comb are all mounted in a single oscillating frame. about which it o'scillatesis below the cylinder, the movements of the several parts being obtained by connections to fixed parts. In this construction the nipper oscillates in a path eccentric to the cylinder and is further away from the needles of the cylinder at the commencement of the oscillation than at the finish and consequently the cotton held by the nipper is not equally combed by all the rows of needles of the cylinder.

The object of this invention is to maintain the nippers when closed as they move or rock to and fro, a constant distance from the needles of the cylinder and to get the cotton held by the nipper s down to the path of the needles of the cylinder in advance of each revolution.

According to the invention the nipper frame is carried on a bearing frame oscillating about the axis of the cylinder and in a path concentric with the cylinder.

The invention will be fully described with reference to the accompanying drawings in which a oomber head embodying the invention is illustrated.

Fig. 1' is an end elevation showing; the

nipper in: its advancedposition towards the detaching roller's,'the nipper jaw raised and Fig. 2 is a transverse section showing the parts in the same position as Fig. 1.

Fig. 3 is a transverse sectionshowing the parts in position. during combing operation furthest from the detaching rollers.

Fig. 4 is a detail of the feed roller ratchet.

Fig. 5 is an elevation looking from back in direction. of arrow Fig. 1..

Fig. 6 is a perspective view of the hearing The centre i feria1 No. 590,719.

Fig. 7 is a perspective View of one end of the nipper frame C.

The detaching rollers A are -1nounted to operate in the ordinary way and the cylinder A" is of ordinary or known construc tion mounted on a haft; c carriedin been lngs a on the standard or frame of the machine. v

An oscillating bearing frame Bis mounted on the bearings a, concentriewi-th the cylinder shaft aandisfree to oscillate around the cylinder shaft a.- The bearing frame B is provided with bearings 12 at both ends to support and carry the nipper frame G.

The nipper frame 0 is constructed with a longitudinal plate 0 with short upstanding portions formed with a pivot- 0' at each end bywhich it is mounted in the bearings b of the bearing frame in which it is capable of rocking for alimited distance to allow the nipper when closed to oscillate at a con stant distance from the needles. For the purpose of adjusting the position of the nipper frame C in relation to the bearing framein either direction set screws 6 are screwed into lugs orprojections thereomthe back screw to adjust the height of the cushion plate D relative to the steel detaching roller A and the front screw to adjust the descent ofthe nipper knife and plate D to the desired distance from the cylinder needles. It is provided at both ends with upwardly projecting lugs or cheeks c to carry the top nipper jaw E, the top comb F and the feed roller Gr, all of the members being thus carried on the nipper frame C which is itself pivotally carried 'on bearing frame B.

The cushion plate D forming the bottom jaw of the nipper maybe formed by the I arms or levers 71. on the roc-kingsh-a'ft K. The

studs 6 are substantially the same distance from the plane of plate 0' as the pivots- 0..

The arms 6 of the nipper jaw or knife extend rearwards beyond the nipper frame and are attached to springs e which are anchored to a fixed part of the frame.

The arms f carrying the top comb F are pivoted to the upper end of the lugs or cheeks c of the nipple frame C and the feed roller arms 9 are also pivoted on adjustable studs carried by the lugs or cheeks 0 the feed roller being rotated intermittently by a ratchet and pawl as the nipper frame C and nipper is moved forward. The rearward enlarged ends of the feed roll arms are connected by adjustable springs to the upper parts of the checks a so that the feed roll is thereby spring-pressed against the cushion plate D.

R A stationary cam or inclined surface M is adjustably secured to the machine frame adjacent each top comb arm 7 to support the bowls m on said arms and thereby control and operate the top comb, giving the desired lift and fall in the familiar manner. Similarly a stationary cam N, adjustably supported on a fixed cross-bar of the machine at about the center of the combing head, is engaged by the bowl n centrally journaled on the cross-rod which connects the two nipper arms 6. This cam causes the nipper knife E to open at the desired time as will be understood.

The whole mechanism receives its oscillating or rocking movement from a rocking shaft K (operated by cams not shown) through the arms or levers 71. and connecting rods H pivoted to the nipper frame C on the studs (2'.

In operation as the bearing frame B oscillates and moves forward towards the detaching rollers A it carries with it the nippers D, E, the top comb F and the feed roller G. Towards the end of the forward movement the runner a contacts with the fixed cam plate N and causes the top nipper aw to move away from the cushion plate allowing the cushion plate to rise oscillating on the bearing 0 to the extent permitted by the rear set screw and at the same time opening the nippers and releasing the fibre therefrom. The runners 771. of the top comb F traverse along the incline or cam plate M and allow the top comb to fall into position and the ratchet of the feed roller G is advanced as the g is held by the pin 9 As the hearing frame B oscillates and moves away from the detaching rollers A, the nipper E and top comb move back with it, the runner a 011 the nipper arm leaves the cam plate N and the spring causes the top nipper jaw to close on the cushion plate and hold the cotton and at the same time forces the nipper downwards closer to the needles of the cylinder to the position determined by the front set screw 0 and the runners on of the top comb F traverse the incline cam plate M and lift the top comb F.

What I claim as my invention and desire to protect by Letters Patent is 1. In a comber an oscillating frame or bracket carrying the nipper, top comb and feed roller, pivoted concentrically with the cylinder shaft and oscillating around the axis of the cylinder at a constant distance from the cylinder.

2.
