TO WHOM IT MAY CONCERN:

.Be it known that I, GEORGE S. HAWOOD, of Boston, in the county'of Sulolk, and-State of Massachusetts, have invented certain new andl useful Improvements in Card-Feeding Machines;v and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure 1 is a front elevation ot a card-feeder to which my improvements are applied.

Figure 2 is a plan view of the traversing guide and rolls, looking from beneath; and

Figure 3 is'a longitudinal vertical section ot' the same.v

My invention relates to a machine in general use for feeding cards, for which Letters Patent of the United States, No. 18,888, were issued to James Apperly and W. Clissold, and it has special reference to the traversingrollers, which carry thc sliver from one side to the other of the machine, depositing it with the lifting-catches on euch side. In the working of this machine considerable annoyance has been experienced from the small particles of waste working between .the rolls and the plate to which they are attached, and from which they depend, clicking' the rolls, and preventing their revolution. In some cases, also, (with a very small sliver, for instance,) it has been possible furthe sliver to slip between the ring or guide which admits it to the rolls and the rolls themselves, and then under the rolls, causing it to break down... To obviate these diiculties is theobject ot my invention, which consists essentially, rst, in the combination with the traversing-rolls of a countersunkplate, for carrying the rolls', under such an arrangement that the upper portion of the rolls is received into the plate, which forms a cap fitting closely over their tops; second, in forming the guide or ring attached to the traverse-plate with a lip or guard, extending partly around and between the rollers, seas to "support and prevent the slipping down of the sliver. l

To enable others skilled in the art to understand and use my invention, I will now proceed to describe the manner in which the saine'is or may be carried into effect, by reference to the drawings. i

In iig. lis represented such portion of a self-acting feeder as required to fully illustrate my invention.

The travelling guide a moves from one side to the other ofthe machine, being actuated4 for this purpose by suit'- able mechanism. The sliver passes to the traversing-rolls 6 through a ring, c, in the front part of tho traverse--A plato d, and is laid in continuous diagonal rows upon an endless apron, which carries it to the card. The traversing-rolls b are attached tol the under `side of'the plate d by means of pins f, upon which they revolve. In the machine, as ordinarily constructed, the under face of the plate is at and without indentation, so that there is nothing to prevent the waste working in between the top of the rolls and the plate, thus giving rise to' the annoyances above mentioned. In order to obviatethis diiliculty, I construct the plate so that, at the points where the rolls are attached, it shall be countersunk, or provided with circular recesses, z, thus forming caps, in

which the rolls 'are set, and which, while tting close enough to exclude all waste, allow the rolls to move easily and freely on their axes. A plate 'of this construction can be readily enst or otherwise formed, and can be made quite as cheaply 'as the ordinary plate.

The ring or guido c, through which the sliver passes to the traversing-rolls, is provided with a lip or guard,

c, which forms a continuation of the lower part of the ring, and extends partly around and between the rollers,

as shown in iig. 2. The sliver passing in through the ring, is thus kept from slipping down between the ring andthe rolls, or under the rolls themselves,- being supported and upheld'by' the lip, which passes far enough around andbetween the rolls to entirely prevent the happening of any such contingency. The lip or guide- Having described my invention, and the manner in which the same 1s or may be carried into effect, what I claim, and desire to secure vby Letters Patentfisl. In, a card-feeding machine, lsuch as described, the platefor carrying the'traversing-rolls, constructed as herein specified, that is to say, countersunk,I or provided with recesses, so as to form a cap or covering for the said rolls, substantially as and for the purposes set forth. v v l y '2. The guide or ring attached to the traverse-plate, provided with a lip or guard, extending between and partly around the rollers, asand for the purposes specified. A l

may, of course, be extended more or less around the rolls, as deemed desirable.
