LAP-FEEDING DEVICE FOR CARDING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 290,378, dated December 18, 1883.

Application filed November 17, 1882. (No model.)

To all whom, it may concern:

Be it known that 1, ROBERT NVILDE, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Lap-Feeding Devices for Garding-Machines, of which the following is a specification.

My invention consists of certain improvements in mechanism for receiving the web of fibers from the doffer of a breaker cardingmachine, and conveying said web to the lickerin of the second breaker or condenser, my improvements relating especially to the mechanism employed for condensing the web of fibers and changing the direction of movement of the same, and to the construction of the camelback feeder forming part of the device.

In the accompanying drawings, Figure 1 is a perspective view,*partly in section, showing part of a breaker and part of a finisher or condenser carding-machine with my improved conveyer applied thereto; and Fig. 2, Sheet 2, a plan View of the same.

A is part of the main cylinder of the breaker; B, the doffer of the same, D, part of the main cylinder of the condenser, and E part of the licker-in.

Extending transversely across the ends of the carding-machines are frames F F, which support the lap-conveying mechanism. The latter comprises an endless apron, G, and a device known as a camel-back feeder, consisting of an endless apron, H, rollers a, b, d, and f, carrying said apron, two pairs of jointed arms, g, and two frames, h h, carrying rollers 'i i, and having wheels k, adapted to run on rails formed by the tops of the frames F, the frames h being reciprocated, as usual, by means of an endless belt, m, running along the inside of one of the frames F, and having a pin adapted to a slot in one of the frames h, as shown in Fig. 1. The web from the breaker-card is removed from the doffer by the roller n, and passes onto an endless apron, J, andbeneath rollers 2, adapted to bearings in extensions of the main frame of the carding-machine. Instead of this arrangement, however, the'web may be removed from the doffer by means of a vibrating comb, and delivered by the latter directly onto the endless apron J. At the end of the apron J is a roller, s, which serves, as described hereinafter, to aid in the delivery of the web onto the apron G, which traverses in a direction at right angles to that of the apron J. The effect of this is to change the direction of the fibers and condense the thin fleecy web into a comparatively thick and narrow strip, which passes under a roller, 25, and thence onto the endless belt H of the camel-back feeder, from between the rollers 41 i of which it is delivered onto the feedingapron K of the condenser-card. Owing to the reciprocation of the frames carrying the rollers i t, the fibrous strip is carried to and fro transversely across the apron K, the speed of the latter bearing such relation to the speed of the feeder that the folds are laid closely together or slightly overlapping one another.

In a former patent granted to myself and T. B. WVilde on the 6th day of April, 1880, I described the use of a camel-back feeder in connection with three conveying-apronsnamely, the apron J, an apron at right angles there to, and an intervening apron at an angle of forty-five degrees. The present arrangement is more compact, and provides for the more effective condensation of the web of fiber than that shown in the said patent. The roller 8 at the end of the apron J serves to compress and condense the web of fibers, so as to prevent the same from being carried around with the apron and insure their delivery onto the apron G, and the roller 15 has a similar effect upon the thickened web presented to it by said apron G, the pressure of the roller upon this web, moreover, serving to prevent the camel-back apron from lifting the web from the surface of the apron G before it reaches the end of the same, thus lessening the risk of breaking the web. I also render the camel back feeder more compact than usual by dispensing with the ordinary counterbalancing devices used in connection therewith, and substituting therefor a single shaft, 10, having two scroll-pulleys, w 00, and a pulley, 3 To the pulleys x are adapted cords connected to the frames h h, and round the pulley yis wound, in the opposite direction, a cord, y, carrying a weight. Owing to the use of the scroll -pulleys, a constantly-varying leverage is exerted, and this is as it should be, for as the lower ends of the jointed arms 9 are moved from and toward each other the weight or strain to be counterbalanced varies in the same ratio. In the present instance the drum 3/ is conical, in order to assist the scroll-wheels x in their action, the cord 3 unwinding from the large to the small end of the drum as the cords x are wound from the small to the large ends of the scro1l-pulleys. This, however, is not essential, nor is it necessary to use two scroll-pulleys, as one may be found to be sufficient in some cases.

Various devices may be adopted for driving the different parts of the apparatus. In the present instance the shaft of the roller a is driven by means of spur-wheels l 2, shaft 3, and bevel-wheels 4 5 from the shaft 6 of the carding-machine, the apron G is driven by a chain belt, 7, from the shaft of the roller a, and the endless belt m, which operates the camel-back, is also driven from the said shaft through the medium of a chain belt, 8, and pulleys 9 and 10.

I claim as my invention 1. The combination of the breaker-card and its apron J, the roller 8 at the end of the latter, the endless apron G,at right angles to the apron J, a camel-back feeder, and an apron, K, serving as a feeder to a second breaker or condenser card, as set forth.

2. The combination of the breaker-card and its apron J, the endless apron G, at right angles to the apron J, the camel-back feeder, the roller 1, bearing upon the apron G at that end adjacent to said camel-back feeder, and the apron K, serving as a feeder to a second breaker or condenser card, as set forth.

3. The combination of the pivoted arms 9, apron H, and carriage h of a camel -back feeder, with mechanism for traversing the carriage, and with a shaft, 10, having a scrolldrum, x, and drum '1, a cord, as, connected to the drum x and carriage h, and a weighted cord, 3/, connected to the drum 1, as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ROBERT WILDE.
