(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L, 1313.)

To all whom it may concern:

Be it known that 1, JOHN WVILLIAM NASMITH, of Stockport, England, have invented certain new and useful Improvements in Combing Machines, of which the following is a specification.

This invention relates to combing machines for textile fibres and one object is to provide combing machines by which a considerable saving in floor space can be effected. To this and other ends I so construct a combing machine that the working parts are all accessible from the top or front of the machine or from the top and front. By this construction two separate machines may be, placed back to back or one machine may be placed against a wall, no back passage being required in either case. When a double comber is formed by placing two of the improved single combing machines with their backs close, together the double comber will occupy about the same floor space as the present single machine with its back passage: This result is due. partly to the abolition. of the back passages and partly to the fact that each machine may be slightly narrower than the single machine as at present constructed. In the double combers according to this invention preferably only the heads constituting each machine are driven from one belt or strap so that if one head is defective and requires repairs or adjustment only the machine to which it pertains need be stopped until the required repairs or adjustments have been made, the other machine of the double comber continuing to work, thus only half of the lapsbeing worked by the double comber are brought to a standstill.

In a preferred construction according to this invention the nipper shaft and other mechanism for impartingthe to and fro motion to the nipper are mounted in front of the cylinder, but it may conveniently be mounted above the cylinder; the nippcr frame and the top comb, or the top comb only, are hinged in front of the combing cylinder; and the top comb may be arranged to travel with the nipper, but a shorter distance. The nipper may be adapted to be lifted or turned over to expose the needlesegments as described in the specification of my Patent No. 1,239,122; and the point of the nipper may be guided in a definite path as described in the specification of my Patent No. 1,239,123.

The accompanying drawings illustrate, by way of example, several kinds of combing machines with my improvements applied thereto.

In the said drawings Figure 1 is a sectional side elevation of two single machines according to this invention arranged back to back and thereby constituting a double combcr;

Figure 2 is a plan of one of the combing heads shown in Figure l; V

Figure 3 is a sectional view showing the nlpper open, and representing in dottcdlnms the entire nipper thrown back.

First, referring more particularly to one of the two single machines shown in Figure 1,B D are the brush and do'hfer respectively, C is the combing cylinder, and N N are respectively the upper and lower jaws of the nipper. N is a nipper shaft upon which is keyed a lever 3 carrying a fixed stud 2 upon which the nipper frame 1 is hinged; this frame 1 carries the lower jaw N and a stud 5 carrying a bowl 6 which runs upon a shaped or formed guide 8 which may be adjustably mounted on the frame of the machine all as described in the specification of my Patent 1,239,123. 7 is the arm carrying the upper jaw of the nipper; it is, in the example shown, pivotally mounted upon a stud 11 fixed in the frame 1, but it may, for example, be hinged on the stud 5 and controlled as described with reference to the construction shown in Figure 3 of the specification of my said Patent 1,239,123. Upon the stud 11 there is also provided a lever 12 which is adapted to be locked to the arm 7 by a latch 13 so that the lever 12 participates in the movement of the frame 1 operated by the oscillatin lever 8. The lever 12 carries a bowl 14: at its lower extremity and this bowl bears against an adjustable block 15 to open the nipper. Loosely mounted upon the shaft N is a pendent lever 16 that is pulled constantly toward the block 15 by a spring 16 attached to its lower extremity. The lever 16 is provided with a projection that comes in contact with the bowl 1 1, and with a set screw 17 that fixes its position relatively to the bloc: 15.

After the nipper has been closed the bowl 14; will leave the block 15 as the nipper continues its movement and will press against the lever 16 forcing the screw 17 from its support so that the force of the spring is transferred to the lever 12 and presses the nipper tightly shut to grip the material during combing. The top comb arm 155 is hinged upon a stud 4- upon the arm 3 and nearer the centre of the shaft N than the stud 2, so that the top comb moves exactly in time with the nipper but with a shorter amplitude of motion. By this means the top comb may be made to enter the nipper beard well in advance of the nipping point and still permit the nipper to approach close to the top comb when both are at the eX- tremity of their forward path and close to the detaching rollers at the end of the detaching period. In this way cleaner work is obtained without greater amount of waste and the top comb keeps cleaner.

28 is a bowl carried by the arm 7 and having its stud extending through a slotted bracket rising from the top comb arm 18. Said bowl normally rests upon the upper surface of the nipper frame 1 and enables the height of the top comb to be adjusted. If the arm 18 were pivoted upon the stud 2 a set screw only could be employed since the top comb arm 18 and the nipper frame 1 would be moving together.

19 is a stud fixedinthe arm 3andhaving a rod 20 pivoted thereon; this rod 20 carries a weight hook 21, which is adjustable horizontally upon the said rod. The hooked end of the member 21 engages with the pivot of the rollers 10, which, as the lever oscillates, rolls round the roller 9 for the purpose described in the specification of my British Letters Patent No. 16001 of the year 1901. To the lower end of the hook 521 is attached a weight 21 that acts to continually draw the roller 10 against the roller 9. j

The path of the lap to the feed rollers and that of the combed fleece from the detaching rollers and between the arms 18 of the top comb are indicated by the heavy broken lines.

From the description given above it will be seen that there are no operative parts hehind the machine so that access thereto is quite unnecessary thus enabling two machines to be placed back to back on a main frame A, as shown in Figure 1. By raising the latch 13 the top nipper jaw may be lifted, and by slipping the lever 12 off its pin 11a simple operation that disturbs no adjustmentsthe'whole nipper hinging upon the stud 2 may be lifted quite away from the cylinder, exposing the comb segment for dressing and cleaning or allowing the segment to be easily removed when replacement by a new one is necessary.

It will be understood that there can be modification of some of the details of the mechanism illustrated without departing from the scope of the invention, and the following claims are only intended to be limited to such of said details as are specifically recited therein.

I claim- 1. In a combing machine, the combination of a combing cylinder, a nipper for holding the material during the combing operation, means for combing the material including a top comb having arms pivoted in front of the combing cylinder, means for feeding the material to the combing means, and means for detaching and piecing the combed material.

In a combing machine, the combination of a nipper for holding the material during the combing operation, a frame pivoted in front of the combing cylinder and upon which. the nipper is mounted, means for combing the material including a top comb having arms pivoted in front of the combing cylinder, means for feeding the material to the combing means, and means for detaching and piecing the combed material.

3. The combination of a supporting frame, a pair of independently driven combing machines arranged back to back on said frame, and each comprising a cylinder and co-operating means for combing the material, means for feeding the material to the combing means, mea-nsrfor detaching and piecing the combed material and a nipper for holding the material during the combing having its frame pivoted in front of the combing cylinder.

l. The combination of a supporting frame, a pair of independently driven combing machines arranged back to back on said frame, and each comprising means for combing the material, including a cylinder and a top comb having arms pivoted in front of the cylinder, means for feeding material to the combing means, means for detaching and piecing the combed material, and a nipper for holding the material during the combing having its frame pivoted in front of the combing cylinder. 7

5. In a combing machine, the combination of means for combing the material including a top comb provided with needles, means for feeding material to the combing means, a nipper for holding the material during the combing operation, means for detaching and piecing the combed material, and means for actuating the top comb and nipper to cause the points of the needles of said comb to travel with but a shorter distance than the nipper. V

6. In a combing machine, the combination of a combing cylinder, a pivotally mounted nipper for holding the material during the combing operation, a pivotally mounted top comb, and a pivotally mounted common support for both the nipper and top comb, the connection of said support and nipper frame ing its frame pivotally connected to said arm, and a top comb pivotally connected to the same arm at a point between the connection of the nipper thereto and the shaft on Which said arm is mounted, substantially as and for the purposes described.
