CARDIN G-MACHINE.

Specification of Letters Patent.

Patented Oct. 31, 1916.

Application filed July 2, 1914. Serial No. 848,617.

To all whom it 'mdy concern Be it known that I, ROBERT S. IVALLAGE, a citizen of the United, States, residing at F itchburg, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Carding-Maehines, of which the following is a specification.

My invention relates to an improvement in carding machines, and the object is to provide a fly or waste roll for receiving the waste that may be thrown out between the licker-in roll and the cylinder or swift.

The invention relates to still other novel features of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in top plan of a portion of a carding machine showing the manner of locating the invention; and Fig. 2 is a detail view in elevation showing the manner of mounting the improved fly or waste roll. Fig. 3 is a section through the licker-in, cylinder and fly rolls.

A represents the frame of the carding machine, upon which is mounted the lap roll 1. The feed roll 2 is mounted in advance of the lap roll. A licker-in roll 3 is mounted on the frame in advance of the feed roll. The pulley 4 is mounted on the licker-in roll whereby power may be transmitted thereto. The feed roll and lap roll are connected together by means of a belt 5 passing over pulleys 6 and 7 on the rolls 2 and 1 respectively. The feed roll is provided with a large bevel gear 8, which is driven by a shaft 9 which is provided with a beveled pinion 10, which meshes with the bevel gear 8. Located adjacent to the lickerin roll is the large cylinder or swift B. A cover or housing 11 is mounted over a portion of the licker-in roll 3, and mounted in brackets 12 connected to the housing is a fly or waste roll 13, which is provided with a large friction wheel 14, which meshes with the friction wheel 8, transmitting power thereto. As the cotton is drawn into the machine by the licker-in roll, it is taken upor seized by the large cylinder B, which revolves at a much higher speed.

The filaments which are seized and carried by the cylinder B are teased or drawn out of the teeth of the cylinder by the roller C, which moves more slowly than the lickerin roll 3, and picks the neps off the cylinder. These neps are carried around by the roller 0, and are caught by the lickcr-in roll, which presents them again to the cylinder B with fresh material from the lap.

The method of carding is the same as that pursued with carding machines in general.

use, as the filaments which are drawn from the end of the lap and conducted by the licker-in roll to the cylinder, there is a tendency for the filaments to fly or be thrown out, and by placing the fly roll 13 in a position between the cylinder and licker-in roll so that the filaments will be caught thereby, a great saving will be made by the roll catching the filaments which are not taken up by the cylinder. The roll 13 is different from the ordinary stripping roll, because it is not intended for such a purpose, but is merely located in such a position between the cylinder and licker-in roll that it may catch any of the filaments or material that may H or be thrown between said cylinder and lie er- 'that may issue therefrom without interfering with the operation of the cylinder.

3. In a carding machine, the combination with a cylinder and licker-in roll, of a housing over said licker-in roll, and a fly roll movably mounted upon said housing to receive the fly that may issue from between said licker-in roll and cylinder.

4. In a carding machine, the combination with linder and licker-in roll, and a re mov. t i roll located in a position between the h cr-in and cylinder rolls to receive the waste or fly that may issue from between said cylinder and licker-in rolls, said fly roll adapted to move away from said rolls as the circumference of the fly roll increases by the accumulation of the waste or fly thereon.

5. In a carding machine, the combination with a cylinder and licker-in roll, of housings over each roll, having an opening formed between their adjacent ends, and a Hy roll mounted on one of the housings and in engagement with each housing for collecting the waste or fly that issues through th opening between said housings.

(i. In a carding machine, the combination with a cylinder and a licker-in roll, of housings over each roll having an opening formed between their adjacent ends, a fly roll mounted on one of the housings and in engagcment with each'housing for collecting the :te o1- flv that issues through the opening; between the housings, power means, and means connected to the fly roll in engagement with the power means for transmitting mo tion to the fly roll, said roll adapted to move 1 utward as the circumference of the roll increases by the accumulation of the waste thereon, and means for governing said move ment of the roll and maintaining the traction means inengagement with the power means.

7. In a carding machine, the combination of a lieker-in roll and a cylinder, and rotatable removable means located in a position between the licker-in roll and cylinder to receive the fly that may issue from between said cylinder and licker-in roll.

8. In a carding machine, the combination of a licker-in roll and cylinder, and positively driven rotatable means located in a position between the licker-in roll and cylin- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents, Washington, D. C.
