(o1. Isl-106) This invention relates to wool carding machines. Carding machines being well known in the art the invention relates specifically to improvements in dofiers and the sliver mechanism of carding machines.

Carding machines are generally employed for mass manufacturing purposes, nevertheless, many people spin their own wool and it has been found that the long slivers of wool produced from carding machines are unsuitablefor home use, it is therefore the primary object of this invention to .provide means adaptable to carding machines whereby slivers of wool may be produced of a predetermined and desiredlength and thickness.

The length of the sliver will depend on the type ,of roller used which may vary according .to the dictates .of my invention; and the width of the sliver will depend on the number of sections of carding points on the dofiersof my invention.

\ Another objectof my invention is the provision of a simple, inexpensive and improved mechanism which produces slivers of wool'from the filmy sheets of wool fibres off the doffers.

Theinvention further comprises the adaptability of my improvements to existing carding machines with only minor structural modifications.

The invention further comprises the provision of an improved device for carding machines which increases production, decreases production and. maintenance costs and is simple, durable and efficient in operation.

A further feature of this invention is the fact that it is adapted to use wool fibers'from discard-- ed wool garments and discarded materials for the purpose of providing wool to be spun on a domestic spinning wheel.

With the above objects and others which may appear as the description proceeds we refer to the drawings in which:

Figure 1 is a diagrammatic machine.

Figure 2 is a fragmentary top plan view of a view of a carding carding machine illustrating one embodiment of my invention, one bin only is shown.

Figure 3 is a fragmentary perspective view thereof.

Figure 4 is a fragmentary diagrammatic view of one dofler, velour roller, sliver tray and bin.

Figure 5 illustrates one embodiment of my improved doffer and velour roll-er.

Figure 6 illustrates another embodiment of the rollers of Figure 5, and

Figure 7 is a still further embodiment of the rollers.

Referring now to the drawings in which similar reference characters designate similar parts throughout the several views, the invention resides inimprovements in thedoffers, velour rollers and sliver trays of a carding machine and reference is had to Figures 1 to. 3 which illustrate bydiagram and fragmentary views a carding machine for the purpose of opening up, separating and forming'a sliver of limited length from short length wool fibres. I

Carding machines are well known in the art and a cursory reference is sufiicient for the purpose of this application.

The wool is fed from the hopper feeder H] to the feed rollers H and ultimately over the swift [2 where it is subjected to violent carding between the swift and the workers I3. Finally the fancy l4 lifts the carded wool ofi the swift where it rests on thesurface of the wire points. With the wool in this position the swift meets the doifers l5 which lifts the wool off the points of the swift in a filmy sh eet of fibres. whereupon it is picked up .by thevelour rollers B and converted into a thick untwisted rope between the velour rollers l6 and the velour covered sliver trays I1. The rope sliver is finally deposited in suitable bins; such as shown and designated as l 8 in the drawings.

Because the present carding machines produce a sliver of a size unsuitable for domestic weaving such as is practised in many countries my invention comprises the provision of suitable rollers adapted to be attached to any type of carding machine whereby wool slivers in rope form may be produced of any desired length within the width of the machine.

Other features of the invention will be explained as the specification proceeds. Reference to the drawings will disclose the fact that my doifers l5 direct the Wool onto velour rollers l6 disposed adjacent thereto. Referring first to the dofiers l5 it will be seen that they extend half way across the swift I2 in Figures 2 and 3; for example if a 48" carding machine is used the effective length of each doffer is 24". The doffers are located on each side of the machine and one below the other for the most eflicient operation.

Each doffer directs the filmy sheet of wool which it has picked off the swift onto velour rollers "5 which are situated slightly below and in complementary arrangement with their respective doifer i. e. of the same length and position (see Figure 7). The doffers are provided with circumferentially spaced apart lengthwise extending carding strips or ribs l9 for the purpose of directing a predetermined width of wool onto narrow strip having a length about equal to the width of the original web. The velour rollers I6 not only remove the narrow, silver strips from the carding" strips or ribs l9, but'also r011 these strips into a loosely held together untwisted rope which has a length about equal to the width of the original web. These ropes are to be used by the purchaser in forming the desired twisted yarn or thread.

The inherent embodiment of ure 6 I have shown an arrangement whereby three 24 sheets of wool may be taken on a 72'" swift or carding machine. It follows that four or more doffers and velour rollers may be adapted to larger carding machines. Also I may vary the length of the doffers i. e. a 60" carding machine may dispense two 30f slivers, etcetera.

The rollers of Figures 6 and 7 are shown with a reduced portion 20 fixed to the shaft 2|, however I may dispense with the reduced portion vas shown in Figure 5 and if the structure of'the carding machine permits the shaft 2| may be reduced to approximately one-half the length of the carding machine if a suitable bearing seating is provided.

Another feature of my invention is the provision of sliver trays I! in combination with the velour rollers. The said trays are velour covered the invention may be carried out still further, for example in Figand are adjustable relative to the velour rollers.

For maximum efliciency the trays I! should be spaced from the respective velour rollers a distance of about at the side where the wool is received between the roller and the tray and should be spaced about /2" at the side where the wool is dischargedfrom between the roller and the tray. However, this spacing may be varied It is believed that the foregoing has adequately described the purpose, function and construction 7 of my invention and reference is had to the claims it being understood that the invention is subjected to the scope and limit of the claims and that the descriptionand drawings served only for purpose of clarity.

I claim:

1. In a wool carding machine including a swift, a doifer cooperating with said swift and formed with a plurality of circumferentially spaced apart lengthwise extending ribs, theribs of said dofier effecting a withdrawalof strips transversely from the ,web engaged with said swift, a velour roller in complementary arrangement with said dofier and adapted to remove said strips from said doffer, and means co-operating with said velour roller for rolling said strips into untwisted rolls.

2. In a wool carding machine including ,a swift, a doffer cooperating with said swift and formed with a plurality of circumierentially spaced apart lengthwise extending ribs, the ribs of said doffer V effecting a withdrawal of strips transversely from the web engaged with said swift, avelour roller incomplementary arrangement with said dofier and adapted to remove said strips from said dofier, and an arcuate tray co-operating' with said velour roller in transforming said narrow strips into untwisted rolls. I

3;In a wool carding machine as set forth in claim 2 wherein the concave side of saidtray is velour covered. 1
