CONDENSING MECHANISM FOR CARDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 243,241, dated June 21, 1881.

Application filed March 31, 1881.

1" all whom it may concern Be it known that I, MERRILL A. FURBUSH, acitizen of the United States, residingin Philadelphia, Pennsylvania, have invented an Improvement in Oonden singMechanism for Carding-Machines, of which the following is a specification.

My invention consists of the combination, in

a carding-machine, of a series'of ordinary ro- IO tating and reciprocating rub-rolls with reciprocating andtraversing aprons, the object of my invention being to obtain the superior con- (lensing efl'ect of the aprons and the drawing and stretching effect of the rolls, which effect cannot be produced by the aprons alone.

In the accompanying drawings, Figure 1 is a plan view, showing the rub rolls of a cardingmachine combined with the aprons; and Fig. 2, a vertical section on the line 1 2.

A A, Fig. 1, represent portions of the fixed frame of a carding-machine; and B a reciprocating bar adapted to guides on or forming part of the frame, and carrying the bearings a tor the journals 1) of the series of rub-rolls D, 2 5 1), D E, and E, another reciprocating bar below the first carrying the bearin gs for the journals of another set ofrub-rolls, G, G, G F, and F, Fig. 2. The two bars are reciprocate'd in contrary directions by eccentrics H and I, as 0 described in the Letters Patent No. 166,601,

granted to me August 10, 1875.

The shafts b of the rub-rolls pass through and are arranged to slide in and turn with a series of cog-wheels, the hubs of which are 3 5 adapted to a series of bearings, d, on the fixed frame A, the upper and lower set of rolls being geared together by the said wheels, so as to revolve in the direction of the arrows, Fig. 2.

An endless apron, K, of leather or other 40 suitable material, passes round the rollers E (No model.)

E, and another endless apron, K, round the rollers F F.

The slivers stripped from the stripper-cylinder of the carding-machine pass, in the direction of the arrow, first between the upper and lower set of rub-rolls, and thence between the aprons which movein the direction of the arrows, while they are reciprocated in contrary directions simultaneously with the rub-rolls.

The rolling and condensing of the slivers can be more thoroughly accomplished by the combined effect of the two aprons than by the rub-rolls; butthe latter possess this advantage, that there can be a slight drawing or stretching of the slivers as they pass between the rolls, it being the practice in many carding-engines to adopt such gearing that there will be a slight progressive increase in the speed of the rollers from the first to the last, so as to produce the desired drawing effect.

By combining a series of revolving and reciprocating rolls with the reciprocating and traversing aprons, I gain the advantages of both systems, while the combination presents the opportunity of drawing or stretching the slivers as they leave the last rollers and before they are seized by the aprons.

I claim as my invention.

The combination, in a carding-machine, of rotating and reciprocating rub-rolls with traversin g and reciprocating aprons, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MERRILL A. FURBUSH.
