IMPROVEMENT .IN CIARDINGMACHINES.

Specification forming part of Letters Patent No. 5,643, dated June 20, 1848; Reissue No. 532, dated February 23, 1858.

tween th em, con Formably to the description in a patent of the United States issued to me on the lst day of May, 1845, the specification of which bears date the 29th day ot' July, 1844, and to which Letters Patent reference is hereby made for a constructive description thereof. The speed of a point on the surface of the irst cylinder, B, being assumed as one foot, the speed of a point on the cylinders C and D is to be equal to two feet in the same time. The speed in like manner of a point on the large intermittently-iitted cylinder E is to be equal to at least one-third more than the speed of the cylinders C and D. The speed of a point on the hooked tooth-cylinder F is only to be equal to about onetwentieth ot the speed of the cylinder E, and the speed ofa point on the final eylinder,G,is also only to be equal to about one-twentieth of the speed of a point on the large cylinder E. These severally-proportioned speeds of a point on the face of each cylinder are to be given or determinethin the usual manner, by calculating' the relative sizes of the drums or pulleys of each eylinder in comparison with the size of the respective cylinders and the drum from which the motive power is derived. Each eylinder is to be driven in the direction of the curved arrow upon it. When thus'completed and the proportionate speeds ofthe several cylinders duly adjusted, as above set forth, the material to be operated on is to be entered by the apron b and rollers l 1,'thc material passing from the cylinders B and C is taken by the cylinder E onto the cylinder F, which, by its peculiar construction, is adapted t0 hold onto all the knobby, lumpy, or matted fibrous material until the cylinder E has opened it all out, and any portionthat holds onto and goes around with the cylinder F is taken ottl that by the eylinder D, and taken from that by the cylinder E to the cylinder F again. 111 this arrangement the cylinder B acts as a comber, and in this mode of using it the cylinder F becomes a worker in unison with common wire card-cylinders, and thus prasents a new mode of earding wool or other fibrous material that prevents the material coming out of the machine in the state that is technically termed knobbed,77 because the stability of the teeth in the eylinder F prevents any knobby portion of the material from depressing them as the mass rolls under them in To all whom it may concern Be it known that I, STEPHEN 1t. PARK- I-IURs'r, ofthe city of New York, late of West Bloomfield, Orange county, New Jersey, machinist, have invented, made, and applied to use certain new and useful Improvements in Machinery for Garding Cotton, Wool, Flax, or other fibrous materials preparatory to spinning the same into yyarn that such improveupon the particulars set forth in a caveat entered by me in the Patent Office on or about the 29th day of August, 1846, and for which improvements, as now completed by me, I seek Letters Patent of the United States; and I do hereby declare that the said improvements and the mode of applying, conjoining, and operating the same are fully and substantially set forth and shown in the following description and in the drawings annexed to and making part of this speciiication, wherein- Figure l isla plan, Fig. 2 is a sectional elevation, and Fig. 3 is a side elevation, of a earding-machine as made and used by me for these purposes.

The same letters and numbers as marks of reference apply to the same parts in each of the several figures.

A is the frame carrying the working parts of the machine, made of wood or metal or both. a a are two shafts and rollers that carry the feedingapron b, and l l are the feeding'- rollers, fitted in any usual manner. 2 is a shaft to receive a drum to drive and carry the first eylinder, B. 3 is a shaft to receive a drum to carry and drive the first small cylinder, c. 4 is' a shaft to receive a drum and carry and drive the second small cyiinder, D. These cylinders Gand D are fully covered with cardteeth, and the cylinder D is mounted on an auxiliary frame, that also carries the shaft 6 and cylinder F. Beneath these cylinders D and F a shaft, 5, on the main frame is to receive a drum and carry and drive the larger eylinder E, which is titted as an intermitted carding-cylinder with card-sheets e that have the cylinder Eis the eylinder G, mounted on a shaft, 7, which receives a drum to drive the cylinder.

The cylinders B, F, and G are made with flat rings of hooked teeth, with packing beihemanner in which such knobbyportions will and do depress the Wire teeth of the common Workers in carding-machines. Therefore, the application ofthe cylinderF as a Worker ei'ects the earding of brous material in abetter manner than can be attained with the common wire-tooth worker, and the hooked-tooth steelrin g cylinder G acts as a doffer with a like and proportionate effect on the material presented to it by the cylinder E, and any usual mechanical means Willv take the material from the cylt inder G in an equal and continuous sheet, bat,

lor sliver.

The cylinders B, F, and G are shown in the drawings as about one-third the proper diameter for full work, and if the proportions between these and the cylinders C, D, and E are maintained an effective carding-machine is placed Within a very small compass but if the proportionate speeds or nearly those as stated for the travel of a point on the several surfaces is maintained the cylinders C, D, and E may be made larger than shown in the drawin gs, if such enlargement is found useful; and

I do not herebyv confine myself to the number of steel-ring toothed cylinders, as more or less may be used Without any substantial departure from the general arrangement herein described and shown.

What I claim as new and of my own invention, and desire to secure'by Letters Patent of the United States, is

The application of the steel-ring hookedtooth cylinder or cylinders to act as combers, Workers, or doifers, in combination with common Wire-tooth carding, for the purpose of quicker and more effectively opening Wool and other fibrous material, substantially in the m( nner described and shown.

In Witness whereof I have hereunto set my signature this 29th day of September, 1857.
