UNITED STATES PATENT OFFICE.
JOSEPH DAVIS, OF WIL'ION, NEW HAMPSHIRE.
IMPROVEMENT IN WOOL-CARDING-MACHINES.
To all whom it may concern:
Be it known that I, JOSEPH DAVIS, a resident of Wilton, in the county of Hillsborough, and State of New Hampshire, have made an invention of certain new and useful Improvements in Machinery for Oardin g Vool or other Fibrous Material; and I do hereby declare the same to be fully described in the follow ing specification, and represented in the accompanying drawings, of which- Figure l is a top view Fig. 2 a side elevavation, and Fig. 3 a longitudinal and vertical section, of a carding-engine provided or constructed with my invention, the nature of which is as followsthat is to say, it consists in a cardingengine so constructed that each ot' its waste-preventing rollers, which are arranged beneath the main card-cylinder, shall have while in operation a speed or velocity of revolution greater than that of the roller immediatelyin advance of it, the same being for the purpose of preventing the fibrous material or waste from gathering in a mass or roll between any two of such waste-preventing rollers, as it is likely to do when each of them has a like degree of speed. By causing each of such rollers to revolve a little faster than that next in advance of it the waste will be drawn by the former away from thelatter and will be prevented from accumulating in a mass or roll between such rollers; and my invention further consists in a carding-engine as not only constructed so as to have waste-preventing rollers arranged underneath and so as to operate with the main card cylinder, but as having one or more such rollers arranged so as to operate in a similar' manner with the tumbler or licher-in.
In the drawings, A is themain card-cylinder ofthe carding-engine, it having at its rear a card-cylinder, B, usually termed the tumbler77 or licher-in.7 It also has at its front a doft'ercylinder, C. A series ofworkers and strippers is disposed over the upper surface otl the main card-cylinder, the same being as shown at D D D D, Src. Extending underneath the lower lengthwise. Rollers so niade and arranged underneath and combined with a main cardcylinder of a carding-engine, in -manner as described, have constituted the subjects of certain patents heretofore granted to me, the object or purposes of these rollers being duly set forth in such patents. In other words, they serve not only to catch the waste fibers, which may be thrown oft' or fall from the main cardcylinder, but to return them thereto. It has been found, in practice, that when each of these waste-preventingrollers (as they may be termed) is revolved at the same velocity the waste is likely to accumulate between the rollers and there gather in a mass or roll so as to obstruct or impair the correct operation of the engine. In order to prevent this I gradually diminish the number of teeth in their gears.
In Fig. 2 the respective gears ofthe rollers a, b, c, d, @,f, g, and h are shown at t' 7c' Z m n o p q, each being connected with another by an intermediate pinion,r. Another such pinion also intervenes between the last gear, q, and the gear s of the shaft of the doft'er O. NVhen the doifer is inrevolution, its gear s will produce rotary motion ofthe whole series of gears t' kl m n o p q, and, as a matter ofcourse, their rollers a b c d cfg h will be similarly and simultaneously put in revolution. lf the first gear, i, has eighteen teeth, the next gear, 7c, in advance of it, should have a greater number of teeth, such as nineteen, for instance. Each ot' the succeeding gears, l, m, n, o, p, and q, should also also have a number of teeth greater than that of the gear which immediately precedes it-as, for instance, the gear Z should have twenty teeth, the gear m twenty-one teeth, the gear n twent-y-two teeth, the gear o twentythree teeth, the gear p should have twenty-four teeth, and the gear 1 should have twenty-tive teeth.
From the above it will be seen that the first roller, a, will revolve at a speed a little greater than that of the roller Z1 in advance of it. By the term advance,77 as used by me in connection with the word roller;7 I intend to be understood as applying it to that roller of the two which is nearer to the front end of the engine.
The directions of the motions of the main card-cylinder and its Waste-preventing rollers are indicated in Fig. 3 by arrows placed on them respectively.
Besides the series of rollers a, b, c, d, e, f, g, and h applied to the main card-cylinderA,the
engine is constructed with one or more othersviz., t u-ivhich should be arranged under or near the cardcylinder or tumbler B, and so as to operate therewith. They perform with respect to it functions similar to those ofthe said rollers t l) 0 d ef g 7L in their relation with the main card-cylinder.
In the drawings I have not shown the feedin grollers, as their arrangement and purpose are to be substantially the same as Jthose of other earding-englnes.
I claim as my invention- Y 1. Acarding-en gine so constructed that each of its Waste-preventing rollers, a b c, 85e., which are arranged beneath the main card-cylinder, shall have, While in operation, a speed or velocity vofrevoluton greater than that of that for the purpose above explained, but as having one or more other such rollers, t u, arranged so as to operate in a similar manner with the licker-in or tumbler B, the whole being substalr tially as specified.
JOSEPH DAVIS.
