UNITED STATES PATENT OFFICE.
RICHARD GRIFFIN, OF HOLYOKE, MASSACHUSETTS.
CARDING-ENGINE.
SPECIFICATION forming part of Letters Patent No. 587,813, dated August 10, 1897.
Application filed September 28, 1896. Serial No. 607,132. (No model.)
To aZZ whom it may concern.-
Be it known that I, RICHARD GRIFFIN, a citizen of the United States of America, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Oarding-Engines, of which the following is a specification.
This invention relates to carding-engines, and has for its object the prevention of the accumulation of waste fiber between the ends of the main cylinder and its lining and in the space between the under side of the tops and the periphery of said lining and between the ends of the licker-in roll and its guard or cap and between the said roll and its bonnet; and the invention consists of devices applied to the ends of the licker-in roll for the purpose above named, all as hereinafter described, and pointed out in the claims. 7 a
In the drawings forming part of this speci fication, Figure 1 is an elevation, partly in section, of one end of the main cylinder and licker-in roll of a carding-engine. Fig. 2 is a perspective View of a ring adapted to be fitted over each end of the licker-in roll. Fig.
3 is a plan view of one end of a licker-in roll having said ring applied thereto and showing also a portion of the main cylinder. Fig. 4 is a view similar to Fig. 3, showing the relation of the end of the licker-in roller to the main cylinder before the application of my improvement to said roll. Fig. 5 is a perspective view of the top of the main cylinder and showing the position of the tops relative to said cylinder-lining. Fig. 6 is a section through the licker-in roll and its bonnet.
Referring to the drawings, A represents the main cylinder of a carding-engine.
A represents a portion of the frame of the machine.
B represents the licker-in roll; 8, its bonnet.
0 represents a ring applied to each end of the licker-in roll.
D represents the wooden lining, so called, fitted in between the ends of the main cylin-' der and the frame A, and E represents the tops of the carding-engine.
The drawings represent portions of a cotton-carding engine, and in this specification the description of the invention will apply more particularly to this class of machines;
tance from each end thereofsay from line 2' to the end of the rollare free from fiber, and
by the much greater speed of rotation of the main cylinder as compared with the speed of the licker-in roll a draft of air is generated, which passes through the vacant spaces between the teeth on the ends of said roll and is directed against the ends of said main cylinder, which are approximately opposite or in the same plane with the ends of said lickerin roll. Said draft or current of air draws in with it into the space 4 between the ends of the main cylinder A and its lining D and into the space 6 under the'ends 5 of the tops E, which pass close to the periphery of said lining, the loose floating fibers always present near a carding-engine, and also draws loose fibers from the edges of the lap 3, near the ends of the licker-in roll, which fibers accumulate in said spaces above named in quantities sometimes sufficient to clog the main A cylinder. Such accumulations of waste are a serious source of annoyance and loss not only on account of the loss of material, but also because by the rotary motion of the cylinder in close proximity to the fixed parts said waste is rolled up into balls or tufts which frequently pass through the card and become part of the finished roving, thus making an,
imperfect yarn.
The device forming the subject of this invention obviates all of the above objections, and the application thereof to a card results in a very considerable saving of fiber and in the production of a roving free from the balls or tufts above mentioned and is constructed and applied as follows: In applying this device to a carding-machine the licker-in roll is removed and the teeth thereof cut off flush with the face of the roll from each end'thereof toward the center for a sufficient distancesay from the end of the roll to about the line ICO 2, Figs. 3 and 4to permit of the placing on each end of the said roll a ring 0, such as is illustrated in Fig.2 of the drawings and shown in its proper position on one end of said roll in Figs. 1 and 3. This ring may be made of any material of suitable hardness, but preferably of metal, and is turned to such internal diameter as to make it fit snugly on the ends of said licker-in roll, and the thickness of the walls of said ring is substantially equal to the height of the teeth of said roll from the face thereof to the points of the said teeth, whereby when the roll is placed in its position in the card the exterior surface of the ring 0 and the points of the teeth will be in the same plane and will lie inclose proximity to the points of the teeth of the card-clothing with which the main cylinder is covered.
In Figs. 3 and 4 thecotton lap3 (indicated by cross-hatching) is shown between: the teeth of the licker-in roll and the teeth of the main cylinder, and it is seen that said ring occupies the space on said roll formerly occupied by the teeth thereof which received necotton, owing to the impracticabiiity of applying said lap to. the fnl lwidth of said roll. It
is thus seen thatthe space through which the current of air-is drawn into the main cylinder is, entirely stopped ed by the application of the said ring G to the ends of the; roll B, and loose fiebers cannot be drawn into said card, and all: of the parts thereof a re-kept substantially free. from accumulati-ons. of waste, as described- A further-advantage-resulting from the. application of the said rings: 0 to it will not accumulate if the; rings 6 are not i applied on said roll, forifi the: said ringsfare i not therev the waste passesintothe main cylinder, as aboveset forth. To-stopthisaccui .The means preferably used in closing this space is one or more strips of leather 12, or some similar material, rivetedor otherwise secured to the inside surface of the said bonnet, so that said material will bear lightly on the rings 0 when the bonnet is setdown in %position. I-nFig. 1 said bonnet is shown in longitudinal section, and in- Fig. 6 in crossisection, through! one of said rings Said bonnetvrests on the caps H, Fig. 1*, as is cw .jtomary in cards of this class, and said strips 12 do not bear with any appreciable weight onsaid rings.
Having thus described my inventien what ;I claim, and desire to secu-reby Letters; Patent, is
gin-g rings: on each end thereof, as; described, gcom'bi-nedwith the bonnet for said roll hav- -,ing. strips, as 12, secured tortheinner swrfim i thereof, above and. in close proximity to grin-gs, substantially as set forth.
I 2. In a-= carding-engine, in combination, a licker-in roll havin-gfa ringgon each end there of between the. teeth: thereon and the'end of 1 theroll, said rings: having. a circa inferential Zsurface substantially in planewith. the exitremities of said teeth thereon, and the main 5 cylinder of saidenginehavi-ng cloth-ingthere? Eon whose borders, adjoining the ends: of the" isaid' cylinder, extend over the surfiaces of said li'cke-r-in-roll rings, substantially" as: set
;forth. I RICHARD GRIFFIN.
