To alt whom, t may concern.'
Be it known that I, JOHN T. WILD, a citizen of the United States, residing at lNhitinsville, `Worcester county, Massachusetts, have invented the new and useful Improvements in Apparatus for Grinding Top-Flats hereinafter fully described and set forth.
The invention is an improved apparatus for grinding the clothing of the top-flats of carding machines, and consists in the provision, in such apparatus, of a sliding or movable carrier-guide and suitable means for imparting slight movement-s of adjustments thereto, whereby the two carrier-clips which slide upon the carrier-guide, to conduct the top-flats across the face of the grinding cylinder, may be quickly and accurately brought into true alinement with each other, and with the successive top-flats so that the ends of the latter will be thereby caused to seat simultaneously and equally upon the clips, and at the desired angle, and otherwise to occupy positions wherein they will be properly ground. A full engagement is essential to be obtained on each clip and the clips at both ends must for this purpose be truly alined with each other, as otherwise the flat will be out of parallelism with the grinding cylinder as it moves beneath it and will be therefore ground unevenly or more at one end than at the other. As the setting of card flats is varied by thousandths of an inch, the necessity for eX- tremely accurate grinding is obvious.
The invention herein described eliminates the diiiiculties above mentioned by the addition of a simple form of adjust-ment means applied to the carrier-guide itself in a manner which can be adapted to existing grinder apparatus and which is described below in conjunction with the accompanying drawings forming part hereof.
Referring to the latter, Figure l is a front elevation of a top-flat grinding motion as applied to a carding machine, with the central portion of the latter broken away to save space; Fig. 2 is an end elevation of the grinding motion on larger scale; Fig. 3 a front elevation of one end of the grinding motion on the same scale showing certain parts of the carding machine in section; Fig. 4 is a sectional detail on line IV-IV of Fig. 2; Fig, 5 is a detail section on line V-V of Fig. 3; and Fig. 6 is a bottom plan of the sliding clip guide.
In the foregoing figures, l represents the arch plates of an ordinary top-flat carding machine, of which the cylinder is marked 2, the flexible bend 3 and the top-Hats 4, the latter being connected by the usual chain links 5. The construction and functions of these parts will be recognized by those skill-ed in this art without description. The grinding apparatus comprises two grinder stands 6 bolted to the card arches l on opposite sides of the machine and in substantial alinement with each other. Each grinder stand 6 comprises a bracket plate 7 projecting inwardly toward the chain of top-flats and forming a curved runway or track, shown more plainly in Fig. 2, which is arranged to be encountered by the upper stretch of the chain to guide it upwardly toward the clips and the end of the presser lever. |The upper central portion of each grinder stand is cut away to accommodate the grinder cylinder pedestals 12 and upon the two remaining arms or branches 6a of the grinder stands, the carrier-guides 8 of this invention are mounted. For this purpose each of the arms 6at is provided with a milled inner face, indicated at 6b, and suitable lugs 6C (Fig. 6) inwardly projecting therefrom to form a slideway upon or within which the carrier-guide may be moved in the direction of its own length and in the direction of movement of the top-flats. Such movement of the carrier guide is produced by means of a screw 9 which is threaded and locked in a tapped-hole 10 in the edge of one of the arms 6a of the grinder stand so as to be held as a rigid part thereof. The projecting part of the screw is provided with nuts 9a engaged to a part of the carrier-guide, as for instance to the laterally vprojecting lug 8b thereof through which the screw 9 passes. There is preferably one such nut on each side of the lug whereby the operation of one will move the carrierguide on its slideway 6b in one direction and the other in the other. A pair of set screws 8EL threaded in the carrier-guide and passed through oblong slots in the arms 6a, provides for the permanent setting of the carrier guide in its adjusted position.
the pedestal 12, above referred to, of the grinding cylinder 11, which is securely bolted thereto in the space between the arms 6a so as to be adjustable therewith. The bolts for this purpose are marked 12L and appear only in F ig. 2. 'Ihe pedestal comprises' the base block 12 or pedestal proper and a journal-block 13 which is adjustable on the base block in a direction at right angles to the travel of the top-flats. Such adjustment is eifected by an adjusting screw 14 and set by a set screw 15 in the manner shown in the drawing.' Referring to Figs. 4 and 5, the carrier-guide S is grooved on its underside to receive and form a track or slideway for its carrierclip 16 which is formed as a part of a rack bar 16, which latter slides in the groove, being normally urged in a direction contrary to the travel of the flats by means of a weighted segment 17 engaging the rack. The rack is confined to the slideway in the carrier-guide by means of the bottom plates 18 which appear in Figs'. 5 and 6. A throwoff cam 19 is fixed to the carrier-guide on the inner side of the track or slideway in a position to be engaged by the top-flats, in the usual way for disengaging them from the clips, when they have passed the face of the grinding roll. rIhe weighted presser levers 20 are ournaled in the grinder stands and each has one arm 20il extended inwardly under the end portions of the top-flats to raise or press them into engagement with the carrier-clips, and another arm 20, provided with an adjustable stop-screw 21, for limiting the upward movement of the presser arm when not engaged by the flats.
In installing and adjusting the -grinder apparatus above described, the grinder stands having been irst secured to the card arches at exactly the same radial distance from the axis of the card cylinder, and the carrier-guides 8 having also been secured thereto by the set screws 8a a scratch line is then drawn across the face of the card the scratch line andi therefore occupy a plane which is exactly parallel with the axis of the card cylinder and of the top flats. When such adjustment has been accomplished, the screws 8f* are firmly tightened and the journal blocks 13 of the grinding roll are adjusted until the grinding face thereof is parallel with the planes of the carrier-clips.
Claims:
1. Apparatus for grinding the top-flats of carding machines comprising a clip-carrier guide mounted for adjustment in the direction of the movement of the top-flats and carrying a grinding cylinder journal block adjustable thereon transversely to the said movement, in combination with a carrier-clip sliding on the guide and means for pressing successive top-{iats against the same. f
2. Apparatus for grinding the top-flats of carding machines comprising grinder stands fixed to the machine, carrier-guides mounted in slideways in the said stands to move therein parallel with the travel of the toptlats vand means for adjusting the guides in said slideways in combination with carrierclips moving on the carrier-guides and a grinder cylinder and journal blocks therefor adjustable in a direction transverse to the travel of the top-flats.
In testimony whereof, I have signed this specification in the presence of two witnesses.
