FEEDER FOR CARDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 437,304, dated September 30, 1890. Application led March 21, 1890. Serial No. 344,744. (No model.)

To all whom it may concern:

Be it known that I, ELI KEARsLEY, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Feeders for Oarding-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to feeders for cardingmachines; and it consists in certain improvements in the construction of the same, as hereinafter described and claimed. As commonly constructed, the feeder is provided with a carrier formed of an endless toothed apron, which is located in the feed-box and carries the wool or other stock upward therefrom to be fed to the carding-machine. When the box is full, the pressure of material against the carrier is the greatest, and the material in the box is taken up more rapidly than when the box is nearly empty. Sometimes the feed-box becomes exhausted of stock without it being known until the card shows light work. The consequence is that there is often trouble about uneven yarn, and to remedy this I provide a feed-board which is automatic in its operation and is adapted to keep the stock in the feed-box pressed to the carrier with a uniform pressure while any material remains in the box; and in order thatv operatives shall know when the contents of the feed-box are nearly exhausted certain devices are connected with the feeder by means of which an alarm is sounded when the box is nearly empty.

In the accompanying drawings, Figure l is a plan View of a feeder for carding-machines provided with my improvements. Fig. 2 is a central vertical section of the same. Fig. 3 is afront View, and Fig. 4 is a side view of the same.

A designates the feed-box, in which is placed the stock or material to be fed to the cardingmachine.

B indicates a carrier, formed of an endless toothed apron, which moves on rollers w a: for conveying the stock upward from the feedbox.

Within the feed-box is placed a feed-board C, the lower end of which is pivoted at a, so that the board may be swung toward or from the carrier B. To the upper end of the board C are fastened the bent arms b and b', to which are attached theweighted cords c, which extend along the sides of the feed-box over pulleys d. A bracket f is slotted and adjustably secured to the bent arm b by a clampscrew f2, and a spring-rod g, which carries a bell h, is xed in position for contact with the said bracket when the board C has been moved a certain distance towardthe carrier B. A catch e projects from the upper end of the feed-board and connects with a latch or pivoted lever 7c when said board is swung forward. The feed-box may then be filled with material to be fed to the card. The lever k is disconnected from the catch c by the action of a slowly-rotating cam fm, which impinges against an arm of a pivoted lever n, and the latter in turn raises one end of the lever k, i

and'thus releases the feed-board. The feedbox being iilled, the contents are pressed by the board C, the latter being steadily moved toward the carrier by the weights s of the cords c, as the material is taken from the box by the carrier B. When the contents of the box are nearly exhausted, the arm or bracket f, having been adjusted on the arm b, comes in contact with the spring-rod g, and the bell 7L is rung and continues ringing until the board O is moved back from the carrier, when the feed-box may be refilled. AThe bell is kept ringing by the action of a cam p on one end of the shaft r.

I claiml. The combination, with the feed-box of a feeder, of a pivoted feed-board C, provided with bent arms, weighted cords connected with said bent arms and adapted to move said feed-board, an arm or bracket carried by one of said bent arms, the cam p, and a spring- Vrod provided with a bell, said rod being fixed in position for contact with said bracket on the forward movement of the feed-board, substantially as set forth and described.

2. The combination, with the feed-box and pivoted feed-board C, provided with catch e, of pivoted levers lc and n and cam m, the latter being adapted to engage the lever n, which is adapted to move thc lever 7c from catch e, substantially as set forth and described.

In testimony whereof I have affixed my signature in presence of two Witnesses.

ELI KEARSLEY.
