SPECIFICATION forming part of LettersPatent No. 504,968, dated September 12, 1893.

Application filed March 13, 1893. Serial No. 465,743. (No model.)

To all whom it may concern.-

Be it known that we, ERNEST CROWTHER and WILLIAM HENRY CROWTHER, both subjects of Her Majesty the Queen of Great Britain, residing at Pudsey, in the county of York, England, have invented a certain new and useful Improvement in Oarding-Engines, of which the following isa specification.

This invention relates to improvements in scribblers or carding engines or machines for carding wool, cotton and other fibers, the object being to card the fiber under operation thoroughly, and with a saving of time and labor and also to allow the fancy rollers to work with more effect, so as to maintain the swifts or cylinders in better condition which will result in efiecting a great saving in the fibrous material under operation.

According to our invention the scribbler or carding engine is made as is customary, but above the fancy roller on each of the swifts or cylinders we employ an endless apron or lattice, said apron or lattice, being preferably covered with card clothing or teeth, their operation being to draw the fiber 0d the last worker or stripper of the swift or cylinder according as the apron or lattice is arranged. The fiber is carried by the apron or lattice from the last worker or stripper of the first swift or cylinder, and delivered to the first worker or stripper of the next or second swift or cylinder, and so on through the machine, there being the arrangement of apron or lattice between each cylinder or swift and the next succeeding cylinder or swift.

To clearly explain our invention reference is had to the accompanying drawings, in which- Figure 1 is an elevation of a part of a scribbler or carding engine having the endless apron provided with card teeth applied thereto, and Fig. 2 is an elevation showing the arrangement when the apron is not provided with card teeth.

As shown in Fig. 1 the endless apron 1 is provided with card clothing or teeth and is suitably supported, such apron acting to remove the fiber from the last worker 2 of the first swift or cylinder 3 and to convey it to the first worker 4; of the second swift or cylinder 5.

In Fig. 2 the apron 1 is not covered with card clothing, the fiber being removed from the last worker 2 by a stripper 6 which delivers the fiber onto the lattice or apron 1 which in turn delivers it to the first worker 40f the next swift or cylinder 5. We prefer in all cases that the fancy roller 7 should be provided with straight teeth that is teeth Without a heel or bend as is customary.

By the use of our improvements the greater portion of the fiber passes from one swift or cylinder to the next without coming in contact with the fancy roller or dofier. Thus the fancy rollers have little work to do except to keep the swifts or cylinders in working order and less cleaning is necessary. The dofiers remove the shorter fibers and that left by the stripper apron or rollers and all dirt and waste fall to the ground between the doifer and swift.

What we claim is- In a scribbler or carding engine, the combination with a plurality of swifts or cylinders, of workers and fancy rollers adjacentto each swift or cylinder, 3. stripping roller adjacent to the last worker of each swift, and an endless belt removing the fiber from each stripping roller and delivering it over the fancy rollers to the first worker of the succeeding cylinder, substantially as described.

In testimony whereof we have hereunto set our hands in the presence of two subscribing witnesses.

ERNEST OROWTHER. WILLIAM HENRY CROWTHER.
