To all whom it may concern: 7

Be it known that I, GEORGE M. VvHITIN,

United States citizen, residing in Whitinsville, Massachusetts, have invented th foli lowing described Machines.

In the operation of revolving-top -flat cards, the opposing card-clothed surfaces of cylinder andflats are desirably set as close as possible without contact, Thisisdone by appropriate adjustment of the'flexible bends on which the flats travel,.and thet closer the setting, the better and more eflective will be the carding and the less the waste of good flber. The closeness of setting is limited however by the tendency of the flats to sag or draw downwardly when in action, not withstanding their special stiffening elements, and with serious danger of contact and certain injury to the clothing which fact-commonly results in the use of settings, as a matter of safety, which are much coarser than necessary and productive" of needlesswaste. This invention seeks to permitcloser settings, by means of an intermediate flexible bend or supplemental track and special arrangements for supporting the Improvements in Carding- 3 mid-portions of the flats therefrom during their coaction with the cylinder, the said track being subject to adjustment by slight fleXure or otherwise to create a condition of absoluteparallelism between flat and cylinder. By this means, either the setting may be made closer than heretofore or thecard may be built wider to give a larger produc' tion with the settings commonly employed but resulting in improvements in either event. g

In the accompanying drawings:

Figure 1 is a side elevation of the upper portion of a card embodying the invention, familiar parts of the machine being shown only in partial detail;

Fig. 2 is a fragmentary section on the line II-II of Fig. 1; and

Fig. 3 is a fragmentary central plan view with portions broken away and in section, looking down upon the lower course of the chain of flats and the central track or guide.

In these figures, 2 designates the side frames, 3 the card arches, i the card cylinder, 5 the chain of flats, and 6 the flexible bends supported from the arches by brackets 7, which may be assumed to be equipped with the usual bend-adjusting devices, not

shown. The chain of flats may be guided on the flexible bends while running in proxim- 1ty to the cylinder and supported: and returned through the upper course all in the manner and by the means usual in carding machines. f

For the support of the intermediate guiding means of the invention, additional brackets 8 are mounted on the outside faces of'the card arches, between the brackets 7, which they may resemble as respects their manner of mounting and adjustment. They are represented as adjusted by the bolts 9, radlally of the arches,.and clamped in adjusted position by other bolts 10 and there may be as many of such brackets as the carding area requires to give adequate support. The brackets on opposite sides are cross co11- nected by relatively heavy transverse members 11, secured by screws 12 to the top flanges 13 of the brackets and of suitably stifl cross-section. These members extend between the upperand lower courses of the flats, in the intervals unoccupied by other mechanism, and constitute the immediate supports for a central flexible track or guide member 14, disposed immediately above the lower flats and having a radiusof curvature larger than that of the flexible bends, which thus appear withinit, in the side view of Fig. 1. Said guide member may be of various forms, but the double channel or I-beam shown in Fig. 2 is specially suitable, since'it provides, in the lower sides 15 of itslateral recesses, two track-ways for two sets of suspension lugs 16, projecting from the middle'portionsofthe backs of the flats. These surfaces of the channels 15 are accura'telymachined, as are also the under-cut bearing faces of the lugs 16 which ride upon them. The track 1 1- is firmly bolted to the transverse members 11 by the screws 18 which are threaded into the heavy web of the track, and its curvature as well as its radial position are subject to variation by the adjustment of the brackets 8 on which the trans verse members are carried.

The suspension lugs 16, it will be observed are disposed in alternate staggered relation upon the successive flats in the chain there being one lug to each flat, at one side of the track, as shown by Fig. 3, and in this way an adequate clearance is provided between the lugs as the flats round the rollers. at the ends of the courses. The lugs themselves are formed with plate-like bodies 19 riveted to thickened seats 20 on the webs of the flats, their heads, which engage the central track, being widened to afford a maximum bearing surface thereupon. It will be understood that the two sets of track members, that is to say the flexible bends and the intermediate bend or central track, are adjusted in relation to each other and to the card cylinder, so that all the opposing carding surfaces shall have the desired and equal clearance.

Claims:

1. In a revolving flat card, a curved suspension track, and means for suspending the flats from the track while passing beneath it through the portion of their travel in proximity to the cylinder.

2. In a revolving flat card, a. curved supporting track over the intermediate portions of the flats, where they travel in proximity to the cylinder, and suspension lugs on the flats engaging said track.

3. In a revolving flat card, the combination of brackets rising from the framework of the machine at opposite sides, transverse members carried by the brackets passing across the machine between the upper and lower courses of the flats, and supporting and guiding means for the lower flatscarried by said transverse members.

4. In a revolving flat card, the combina tion with the card arches, flexible bends supported by brackets thereon, and a chain of flats guided at their ends on the flexible bends, of other brackets on the arches, transverse members carried by these brackets between the courses of the flats, an intermedi ate suspension track carried by said members, and lugs on the backs of the flats to engage therewith.

5. In a revolving flat card, the combination with card arches, flexible bends adjustably supported therefrom, and a chain of flats guided at their ends upon said flexible bends, of transverse members passing between the courses of the flats likewise adjustably supported from the arches, an intermediate curved supporting track over the active course of the bends carried by said transverse members and adjustable through their connection therewith, and lugs on the backs of the flats adapted to travel on said intermediate track while the ends of the flats rest and move upon the flexible bends.

6. In a revolving flat card having flexible bends and a chain of flats traveling thereon at their ends, the combination of an inermediate curved flexible support over the flats and possessed of a lateral bearing ledge, and lugs on the backs of the flats having bearing faces to engage over and travel upon said ledge at the same time that the ends of the flats are guided upon the flexible bends.

7. In a revolving flat card, the combination with a chain of flats, of an intermediate flat-supporting track, having opposite lateral bearing ledges, and bearing faces on the backs of the flats disposed in alternation at opposite sides of the center of the track and engaged with the ledges thereof.

8. In a revolving flat card, the combination with a chain of flats, of an intermediate curved guide over the active course of the flats, and lugs on the backs of the flats disposed in alternate staggered relation and adapted to engage over opposite sides of the guide.

9. In a revolving flat card, the combination with a chain of flats, of intermediate curved guiding means over the active course of the flats, and lugs in staggered relation upon the backs of the flats for engagement with said guiding means.

10. In a revolving flat card, the combination of flexible guiding supports beneath the ends of the lower flats, and intermediate suspension guiding means for said flats.

In testimony whereof, I have signed this specification.
