IMPROIEMENT IN ALARM FOR CARDING-MACHINE.

TO-ALL WHOM IT MAY CONCERN:

Be it known-that we, JOSEPH HAYruonN and CHARLES E. PRICE, both of '.lhompsonvlle, Hartford county, State of Connecticut, have invented anew and useful Improved Attachment for Cardi ngMachines; and we do hereby declare that the following is a full and clear description thereof, reference being had to the accompanying drawings, and to the letters lor" reference markedthercon.

' In the drawings- Figure 1 is an end view and partial sectional view of my device,

Figure 2 a side' view, partly in section, and A Figure 3 aplan view of the same, @i

yFigure 4 being a d etail view of one of the parts pertaining thereto.

This invention consists of a new and useful improvement in carding-machines, whereby the operator is warned of -the breaking of a strand before it is fed into the machine..

In construction, we form our device as follows A About a foot and a halfI back from the feed-rolls we placetwo pair of rolls, B and C, a few inches apart, each pair having the strands a a a, Svc., topass between them. Between these 4pairs of rolls, B and C, are .arranged vertical posts, 6 b, tc., one post for each strand.v The strand passes 'through a funnel-shaped opening in the top of thepost, holding the latter down, it being operated by a spring,-D, so Vthat 'it constantly presses up. The construction of this post may be varied; however,'without altering the principle involved.

- At the lower end of each of the posts, below the frame E, in which the springs are arranged, is a slot, c, through which a cord, F, extends across ,the bed of the machine,being xed at one end, and attached at` thc other to a bolt or .pin,.G, which it draws inwards when any unusual tension is put upon the cord.

Resting upon this pin G is one end of a lever, H, pivoted near the other end to the side of the machineframefI. At the shorter end is hung a bell, J, the weight of which docs'not overbalance or even equal the weight of the longer vend of the lever. i I

Upon the tumbler-shaft K, is a pulley, with-a pin, L, or a crank or equivalent device, for the purpose of agitating thev bell when the-shorter end of the lever is brought within-reach of-it.

The operation of this device is as follows:

`When'one of the strands breaks, it lets the post corresponding withV it ily up, andthe lower end of it pulls up the cord-.attached to the bolt, as shown in fig. 1A. The lever, having its rest removed, falls, the longer end downwards, bringing the shorter end, with thebell, within reach of the crank, which agitates it as the tumblershaft revolves, and rings the bell. y

The advantages of this device are, that. the operator is enabled to discover the' broken strand, and have plenty of time to mendit, before'it reaches the feed-rolls; and this applies to nearly all cases, for the strands rarely ever `break after the feed-rolls have been passed, and the spring on the post being made of just the proper strength to be held d'own by a sound strand, prevents imperfect ones from passing this point.

Having described our invention, what we claim as new,` and desire to secure hy Letters Patent, is?- The combination of the rolls B and C, spring-posts b b, cord F, with bolt G, and lever H, with its bell, all arranged substantially as described, and applied to a ending-machine, for the purpose set forth.
