IMPROVEMENT IN' FELTING-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom 'it lmay concern Be it known that I, ItUDoLiT1 EICKEMEYER, of Yonkers, in the county of Westchester, and State of New York, have invented certain new and useful Improvements in Machinery for Feltiug Felt Cloths; and Ido hereby declare that thelfollowing is a full and correct description thereof, reference being had to the accompanying drawings, forming apart of this speeitication, and to the letters ofuit erf-ence thereon.

This invention relates to jiggering-machines, in which the material is fed upon a,-car`rying-cloth between a fiat-surfaced jigger anda platen.

In some ofthe jiggering-machines of this class, the jigger'has a continuous action upon the abridand the carrying-cloth or conductor has a slow continuous motion, but such machines do not admit of applying the jiggering-surface to the fabric under heavy pressure,and consequently are only suitable for hardening the fabric, preparatory to the subsequent operation of the fulling-mill. In other machines of this class, the jiggering-apparatus is applied to the fabric, while the carrying-cloth is atrest, and the jiggerin-g proceeded with for a period of time regulatedlbythe machinery when it ceases, and the fabric is moved forward about the distance of thevwidth of the jiggering-apparatus,

and the jiggering again proceeded with, these ope'rations being repeated. to felt a continuons fabric; but such machines necessarily produce unevenly-elted fabrics, because the entire surface of `the fabric is not subjected to the action of all part fof `the jiggering surface, and because the speed of t e: jig-ger and the heat and moisture may. vary upon the successive squares of the fabric successivelyiapted ,upon by the i i v v ltolremedy the defeets last mentioned, .and to producel evenly-felted fabrics, progressively felted bythe operation of the machine. rllhis is accomplishedy bycombining with The object of this invention the mechanism that regulates the periodici time dur ing which the jigger acts upon the fabric to be felted, a mechanism which moves the fabric forward with the carrying-cloth a short distance compared with the width of the jiggering-surfaces, whenever the fabric .is released from the action of the ,jggering-surface,

has repeated its action upon the fa ric and retreated therefrom, these operations bein |repeated until the desired length of fabric is felted.

and then remains at rest until thegjiggering-smface By this mode of operation, all parts of the jiggen' ing-surface are applied to all parts of the fabric passing through the machine during regular and uniform peliods of time, and the fabric thereby becomes uuiforrnly felted. v ,u J

This invention further consists; in combining, with the fe1ting-platen, carrying-cloth,lland. liat-surfaced uiigger, a system of rotating camsanilweighted levers ,ftl l connected with the jigger, substantially as hereinafter described, whereby the jiggering-suriace is pressed upon the fabric with a determinate pressure during regular periods of time, and released from the fabric at regular intervals, in order to permit of the intermittent progressive movement of tl1e'carrying-eloth.

Figure 1 of the drawings represents a longitudinal section of the machine;

Figure 2, au end view; and

Figure 3,' a plan view of the same.

lhe side frames c. a ofthe machine are framed together by the cross-braces a2 a3 ai.

The platen b is secured to the side flames by the screws b* b2 Ifi bi The carrying-cloth c is an endless apron or conductor, of linen, canvas, or other suitable material for a hardening-cloth, extended over the drums l d d di,

and moved intermittently at regular intervals, a short distance, compared v-:itn the width of the platen, inthe direction indicated by the arrows, by a pawl, e, and ratchet e', the latter attached to the` shaft of the drum d.

The flat jigger-plate f forms the top plate of the steam-box f l, and isperforated with fine holes to permit steam to pass to the fabric to be felted.

The steam-box yI has suitable induction and eduction-pipes fzf, (shown broken olf,) which should he connected, by flexible conuectingepipes, with a source of supply of steam and a waste-water receptacle. This steam-box, with its tiatrubbing-surfaee, is placed beneath the platen, under that portion of the carrying-cloth in contact therewith, and receives a very short and exceedingly rapid reciprocating motion from the crank-shaft g, which may be driven as usual by a rapid belt from a separate counter-shaft overhead,

.running upon the driving-pulley gl, and is connectedv with the steam-box j, by two connecting-rods, g2 g3. At each side of the jiggering steam-box, are guides g g5, which do notvinterlere with its being moved to' ward and from the feltiug-eylinder.

rEhe steam-box and its jiggering-surface are moved up and down, and held against the hardening-cloth and felting-cylinder with a yielding pressure, by mechanism, as follows, viz:

The steam-box is supported by four rocking eolumns, two of which, 71. hl, are connected by joints to lugs or projections from the lower part of a sliding plate, t, which slides up and down Within the frame upon the side frame a, the upper part of the sliding plate c' having-a guide-bar, i?, projecting upward from it, which slides in a recess in the end of the cross-braee a, the lower part of the sliding plate being guided by the camshaft, which passes through a slot made in the middle of the lower part of the plate for that purpose; and the other two columns, one only, hshown in the drawings, are similarly connected to an oppo-
