Leners Patent No. 100,247, dated M01/rch 1, 1870.

IMPROVEMENT IN STOP-MECHANISM FOR GARIDING'-MIAGHINE.v

The Schedule .referred to in thesev Letters Patent and making partf the same.

To all whom it may con-cern Be'it known that I, C. W. ANDERSON, of Grosvenor Dale, in the county of Windham, and State of Connecticut, have invented a new and improved Stop- Motion for Carding-Machines; and I do hereby cleclare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the' same, reference being had to the accompanying drawings forming' part of this specification.

This invention relates to devices employed to throw out of gear the driving mechanism of the cal-dingengine when the fibre breaks or doubles, and consists in the combination and arrangement of certain instrumentalities whereby this object may be more conveniently eii'ected, and which will be more particularly specified hereinafter.

' In the accompanying drawing- Figure 1 represents a vertical transrelse section of my invention, the planeof section being indicated by the line :c x, fig. 2. Y

Figure 2 is a front view,.partly in section, of the same.

Figure 3 is a horizontal section of the same, taken on the plane of the line y y,lfig. 1. v

Similar let-ters of reference indicate corresponding parts. y

A, in the drawing, represents the frame of the railway bead.

,B is the shipper-bar.

This bar, when it holds the belt on the tight pulley, is inthe position shown in figs. 2 and 3, and is retained in such position by a lock-lever, C.

y vA spring, D, or itsequivalent, has the tendency, by turning the shaft 1, around which it is coiled, to draw the bar B out by means of the belt J, connect-ed at one end to the bar, and at the other to the shaft I, so as to throw the driving-belt upon the loose pulley.

On the bar B is a spring-catch, a., which serves to engage the lever C.

'lhe lever C is a bell-crank, with a long horizontal and short vertical arm.

The horizontal arm is caught under one arm, b, of an elbow-lever, E, which is pivoted by a vert-ical pin, c, to the frame.

A spring, d, has the tendency to draw the arm b off thelever C.

Through the top plate of the frame A passes a bar, F, which is pivoted to projecting ears, e, as shown, so that it can swing forward and backward on the same.

The lower end of the bar F passesA through the arm f of the elbow-lever E.

Its upper end carries a trumpet or funnel, G, through which the leece is passed.

The cotton, as it is passed through the funnel, swings the same forward, throwing thereby the lower end of the barF inward. This will cause the arm b of the lever E to be held over the long a'rm of thel lever C, whereby the short arm of the latter will beheld against the spring-catch a.

The shipper-bar will thus be locked so as to retain the belt ou the tight pulley.' t

As soon, however, as the. fleece is separated, the strain on the funnel G and bar F will cease, and the spring d will be at liberty to draw the arm b of ther lever E on" the long arm of the lever C. v

The power ofthe spring D willthen be exerted to throw the shipper-bar outward, and shift the belt upon the loose pulley, the lever C being swung out of the way by the power of the spring D.

Thus, as soon as the bers shall be separated, and the eece that vleaves the carding-machine be torn, will the shipper-bar be 'moved tothrow the belt upon the loose pulley, and to thereby arrest the motion of the machine.

H isa lever pivoted to the frame A in front of the lever F. Its front or outer end is designed to rest upon the upper vertically-movable roller h', while its rear end, which has a cam formation, ts against a pin, i, `that projects from the lever F.

When the roller h. is raised by crowding or doubling -of' material between it and the roller h, the lever H 1. The combination of the'mechanism'for operat- Y ing the belt-shipper from the funnel when the sliver breaks, consisting of the vert-ical swinging-bar F, levers C E and springs D d, when constructed and ar-. ranged with respect to each other,v in the manner described. v

2. The combination with the pivoted lever F and the rollers h h' of the loosely-pivoted roller H, constructed and arranged as described, with one end resting over the journal of the movable roller h, and the other provided with a graduated cam bearing against a pin projecting from the lever F, by which the beltshipping mechanism is operated when the sliver vdou-y bles or crowds between the rollers, all as set forth.

3. The combination with a pivoted bar, E, for operating belt-shipping mechanism, of a funnel G affixed to the -top thereof, and a vibrating-lever H, resting with its cam end against the pin t', and operated by the elevation of the looselyjournaled roll h', all arranged as speciied, and for the double purpose of throwing the driving-belt from thefast pulley whenever the sliver breaks or doublesbetween the rolls.
