LAP-FEEDING DEVICE FOR CARDING-MACHINES.

.JPECIPICATION forming part of Letters. Patent No. 348,421, dated August 31, 1886.

Application filed June 9, 1885. Serial No. 165 ,1321. (No model.)

To all whom it may concern.-

Be it known that 1 \VILLIAM SoHoFIELD, 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 Lap-Feeding Devices for Carding-Machines, of which the following is aspecilication, reference being had therein to the accompanying drawings, wherein Figure 1 is a side elevation the first breaker-card, its delivery-apron, part of the supporting-frame for the latter, the apron at right angles to the delivery-apron for transferring the stock or web of fibers to the camel-back of a carding-machine and my improvements applied thereto. Fig. 2 is a detail section, drawn to an enlarged scale, of d riving-wheel, spline, bearing, and shaft for the transferring-aln'on. Fig. 3 is a cross-section of said shaft and spline and wheel sleeve or hub; and Fig. 4 is a plan showing a part of breakercard, part of the condenser-card, the camel-back, and delivery-aprons of a cardingmachine with my improvements, showing modification in the connection of their actuating devices with shafts of the breaker-card.

My invention has relation to carding engines or machines of the form having a camelback feeding device for the feeding-in apron of the condenser-card and an apron arranged at right angles to the deliveryapron of the breaker-card, for transferring the stock or web of fibers to the camel-back; and it has for its object to adapt the carding-engine for working a lower or poorer grade of stock, and also to working to a better advantagea good grade of stock than has heretofore been possible. To accomplish this the stock'or web of fibers, as it passes off of end of the first breaker delivery-apron onto the apron at right angles thereto, is folded or overlapped upon the latter, and in such folded condition is transferred to the camel-back. This overlapping of the stock more uniformly and to a greater extent condenses it, and it is made much strongerthan heretofore, so that it maintains a continuous even width as it is transferred to and passed over the camel-back, and in passing over the latter is not liable to be parted or broken by the rising and falling or closing showing part of and opening movements of the camel-back.

In two applications for oardi rig-engines filed by me of an even date herewith, and serially numbered 168,130 and 168,131, respectively, I have in one of them shown a swinging frame attached to the end of the fixed supporting frame of the breaker delivery-apron frame for effecting the overlapping or folding of the stock upon the transterringapron at right angles to the delivery'apron, and in the other the transferringapron is reciprocated trans- Versel y to overlap the stock upon it. In practice it is found that the employment of both the swinging frame and the reciprocating transferririg-apron, moving in opposite directions, admits of reducing the throw or extent of their movement nearly onehalf to produce the required width of lap of the stock, whereby said parts and their operating devices may be made more compact.

My invention accordingly consists of a carding-maehine'having a swinging frame at the end of the supportingd'rame of the breaker delivery-apron a single longitudinally-traveling and transversely-reciprocating apron at right angles to the delivery-apron, and devices arranged to move said frame and apron in opposite directions.

It the drawings, A represents a part of the main cylinder of the breaker; B, the doffer of the same; 0, the delivery apron;'D, part of the frame supporting apron C; E, a part of the condenser-cylinder; F, a part of the licker-in; G, the feeding-apron therefor; H, the camel-back feeding device, and I the apron, arranged at right angles to apron 0, all of which, except frame D and apron I, may be constructed and arranged for operation in the well-known or other desired way, or as substantially shown in Fig. 4.

To the outer ends, (I, of frame D is pivoted a swinging frame, K, which depends near to and is in position over or above apron 1. Frame K is composed of end bars, k, pivoted at kto the ends d of frame D in any suitable manner, and'the ends it are connected at their lower extremities by parallel bars, rollers, or ties k rollers being preferred, and having secured to one end of their shafts k", outside of the adjacent end bar of frame 1i, grooved pulleys k, which are connected by means of a belt, k with alike pulley, c, secured to the end of shaft 0 of apron C, so that the rollers k will revolve in opposite directions or toward each other at the same rate of speed as that of apron-shaft c. The single endless apron I has its usual forward traveling movement for feeding or transferring the web of fibers to the camel-back; but in addition to said movement it has a simultaneous transverse reciprocating movement.

To admit of the reciprocation of the apron I, its driving-shaft i has a pinion, M, in gear with a rotating shaft, N, of one of the apronrollers of the camel-back H, in the usual manner. (See Fig. 4.) Shaft N is driven from shaft 02 0f the break er by interposition of gearwheels n and a", shaft of, and bevel-wheels n and n. The gear-wheel n on shaft N,meshing with wheel M,gives to the apron I its forward traveling movement; but wheel M is loose upon shaft 1', or is journaled in an adjacent bearing, i by a sleeve, m, through which the shafti passes. An end collar, m, holds the wheel in position, and a feather,m", in its bore entering aslot, i, in the shaft '5 (see more plainly Figs. 2 and 3) permits said shaft to slide as it is rotated by the driving-pinion M.

To relieve the shaft 13 of apron I of the weight of its frame L, it has lower cross-bars, Z, provided with vertically-adjustable brackets Z, having rollers Z, traveling upon floor tracks or Ways Z". The hearing or brackets i are firmly secured to the floor or a support, and are also made vertically adj nstable, to provide for adjusting the apron I at different heights. As the frame K and apron I are moved to and fro in opposite directions, the stock or web of fibers, leaving the apron O and passing down between the rollers is" k, is overlapped upon the apron I, as indicated at x, Fig.1, and this is effected by less movement of said frame and apron than if either were used separately.

Various devices and different modes of gearing them either directly or indirectly to different parts of the carding-engine may be used for operating the frame K andapron I.

In Fig. 1 is shown counter-shafting p and p, having pulleys or wheels 12 and p, rcspectively, driving-belt p connecting these pulleys, a belt-connection, p, from pulley p to doffen shaft 1), rod attachment p, connected at one end to frame L of apron I and at the other is eecentrically attached topulley p in a radial slot formed therein, and a link attachment, 9',

from rod tovone slotted arm r of a lever R, pivoted to frame D, the other slotted arm, 1, of lever B engaging with a stud on one end of frame K, the described connections of the link 10 with pulley p, and link 7' with lever B, and of the arm w of the latter with frame K, being all adjustable to vary the throw or travel of frame K and apron I to make different widths of lap on apron I.

In the above-described connections and arrangement of the actuating devices for apron I and frame K the devices are indirectly connected to-the doffer-shaft; but, if desired, the eccentric connection for rods p may be directly applied to one of the roller or other shafts, b. of the breaker, as shown in Fig. 4, and the like attachment for links or rods r for reciprocating frame K may be attached to another roller or other shaft, 1)", of the breaker, as indicated, and when so arranged the eccentric connection for rods 19 and r with their respective breaker-shafts should be oppositely placed or arranged to give the desired reverse movements to frame K and apron I.

What I claim is- 1. The combination, with the breaker-card delivery-apron O and its supporting-frame D, the swinging frame K, pivoted to the outer ends of said supporting-frame, transverselyreciprocating apron I, at right angles to apron C, and actuating devices for moving said frame and apron in opposite directions, substantially as shown and described.

2. The combination of breaker-card delivery-apron 0, its supporting-frame D, swing ing frame K, transverse reciprocating apron I, at right angles to apron O, camel-back feeding device H, a second breaker or condenser having feeding-apron G, and actuating de vices for swinging frame K and reciprocating apron I, substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

WVILLIAM SOHOFIELD.
