CARDlNG-MACHINE.-

SPECIFICATION forming part of Letters Patent No. 443,415, dated December 23, 1890. Application filed November 8, 1881. Serial No. 254,619. (No model.)

To all whom it may concern:

Be it known that 1, JOHN P. THOMPSON, of Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Carding-Machines, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of this specification.

This invention relates to acarding machine or engine for opening and straightening out cotton, wool, or other fiber.

The object of my invention is to provide what may be termed a double card, which w1ll prove an efficient and economical machine. To the aforesaid purposes my invention, brlefly stated, consists, essentially, in having the licker-in, the carrier-cylinder, and doiferroll arranged in the stated order intermediate the lap-roll and the main cylinder, in having a set of feed-rolls posterior to the lap-supply roll and a set of feed-rolls anterior to the main cylinder, in having the vibrating packer co-operating with the doffer-roll and the doffer and the feed-rolls posterior thereto, in having the traveling conveying-apron for conveying the lap partly through the machine, and in the construction of the vibrating packer and the vibrating doffer.

In order that my invention may be fully understood, I have illustrated in the accompanying drawings and will proceed to describe the best forms thereof so far devisedby me, with the knowledge, however, that such forms admit of modifications.

In the accompanying drawings, Figure 1 is a side view of my improved carding-machine, shown with part of the main cylinder and framing omitted. Fig. 2 is an enlarged side view of a portion of the machine shown in Fig. 1, and shows the drive-shaft and the rockshaft with the doffer and the packer and the intermediateconnections. Fig. 3 is a front view of the part shown in Fig. 2. Fig. 4 is a horizontal sectional view of the parts shown in Fig. 2, the section being taken on line 4 4 of Fig. 2. Fig. 5 is an enlarged side view of a part of the machine shown in Fig. 1, with some of the side framing removed and showin g more clearly the endless conveying-apron under the packer. Fig. 6 is an enlarged detached view of the packer, with the rock-shaft and the loose sleeve of the packer shown in cross-section. Fig. 7 is a sectional view of the packer, taken on line 7 7 in Fig. 6, viewed in the direction of the arrow therein shown, and shows the toothed packer-blades in advance of the toothless blade. The blades in this viewhave central sections shown as broken away. Fig. 8 is a sectional view of the packer, taken on line 8 8 in. Fig. 6, and shows the toothless packer-blade broken away at the center. Fig. 9 is a view of another form of packer, the view being similar to that shown in Fig. 6. Fig. 10 is a sectional view of the packer, taken on line 10 10 in Fig. 9. Fig. 11 is a side view of still another form of packer. Fig. 12 is an enlarged view in detail of a portion of the packer plate or blade shown in Figs. 9 and lO, with a packer finger or tooth mounted therein.

In the said drawings like numbers of reference design ate corresponding parts thro u ghout.

Referring to the drawings, the number 3 designates the ordinary machine-framing, at the right-hand end of which is mounted the lap-supply roll 30, which supplies the fiber to the feed-rolls 31, and 32 is the licker-in, ithe carrier-cylinder, and 5 is the doffer-roll, from whence the lap passes through the feed-rolls 16 to the main cylinder The aforesaid card-cylinders are provided with the usual card-clothing and are mounted to turn in their hearings in a manner well known. Likewise the feed-rolls 31 and 16 are rotary rolls of the ordinary construct-ion, which may have one of each set given a positive motion in the usual manner.

My invention consists in part in the disposition or relativearrangement of these several old devices, together with the novel features,

which I will now proceed to describe.

Near the doiter-roll 5, to the left thereof in the view shown in Fig. 1, the drive-shaft 11 is mounted in the bracket 35, formed with the recess 37, and the shaft is provided with the end of which has a bearing (not shown) on the other side of the machine, and this shaftis provided with the fixed rocker-arm .l, by means of which the shaft may be rocked in its bearings indirectly by the drive shaft 11 through means of the eccentric 30, formed on the drive-shaft and the eccentric-rod 10,0011- necting the eccentric with the rocker-arm 9 by the pivot 38. l'pon the rock-shaft '7 is rigidly secured a pair of arms 39, only one of which is shown, the omitted one being located upon the opposite side of the machine from the one shown, and these arms carry the ordinary dofter-comb ti, which is given a vib 'atory motion by means of the rock-shaft and acts to strip the fieece from the dol'ten roll 5 in the ordinary manner.

My novel packer 1T strikes upon and packs and presses the fleece into a sheet after the same is stripped from the doFter-roll by the dofter-comb, and is given a vibratory motion by the shaft 11 similar to the motion which is given to the dofter-comb by means of the rock-shaft 7. The packer consists in a sleeve 18, mounted loosely 011 the rock-shaft 7 and provided with the internal bearing-ridges 19, and having the packer-arms 20 cast thereon and each formed at the end with the eye 4:0 to receive thebolt ll for attaching to the arms the packer blades or plates 21, which are provided with the packer teeth or fingers 22. The sleeve 18 has a rocking motion imparted to it by the drive-shaft 11, so as to vibrate the packer through the following means: To the sleeve is rigidly secured by the screw t3 the bent rock-arm l2, which projects ovcrinto the recess 37 of bracket 35, and to the end of which is pivoted by means of the pin it the eccentric-bar to, which is connected by its other end to the eccentric 36.

The packer teeth orfingersfli? maybe formed integral with the blades, or they may be separate pieces inserted in the blades, as shown in Figs. 9, 10, and 1:3, wherein the tooth 22 is a cylindrical plug having a forked or notched lower end it i In the construction of the packer shown in Figs. 0, 7, and and the preceding figures there are used a set of toothed blades, together with one toothless blade, and these blades are formed with perforations to receive the bolts and are arranged apart and parallel with the spacing-pieces t7 thcrebetween. In

the forms shown in Fi s. 9 and 11 there is i C) only one blade 21 used, which in the former instance is provided with teeth 22, latter construction is a toothless fiat blade L-shaped in transverse section,

Beneath the packer and doffcr is disposed my improved conveying-apron t8, disposed between the (letter-roll 5 and the feed-rolls 16. This apron is endless and is mounted on the rolls 49, any one of which may be given a positive rotary motion in a suitable way, so asto keep the apron in constant motion in the direction from the dolfenroll toward the teed-rolls 16.

and in the In Fig. 5 a lanai-pulley is shown in broken lines secured to one end of the lower feed-roll 10, and a similar band-pulley is shown secured to the end of the shaft of the roll 4ft immediately under the packer. These two band-pulleys are shown connected with a driving-bant'l, thus imparting motion to the belt t8, delivering the packed fiber to the iced-rolls it at the same speed at which the feedrolls deliver the fiber to the carding-cyliuder.

In the operation of the card the cotton-bat passes from the lap-roll 30 through the feedrolls 3i, whence it is taken by the licker-in 32 and the earrier-cylimler i to the doft'er-roll 5 to open the lap and partially clean and straighten the fibcr, which is stripped from roll 5 by the (letter-comb G, and, coming under the blows of the packer 17, is packed and thence carried by the apron is to the feedrolls 1G, whence it passes to the main cylinder 233.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a cardingenginc, the combination, with the main carding-cylinder,of the following sncccssivcly-operatin g instrnmentalities: a lap-supporting roll, a pair of feed-rolls, a licker-in, a carrylug-cylinder, a doffer-roll and dofiTer-comb, a carrying-apron, a fiber-packing device, and a pair of Eecd-rolls, all constructed to feed the lap to the licker-in, carry the fiber from the licker-in to the (letter-roll, doff the fiber, pack the dotted fiber, and feed the packed fiber to the main carding-cylinder, as described.

2. The combination, in a carding-engine, with the feed-rolls and the licker-in, of a carryingcy1inder, a dotting-cylinder and doll.- ing-coinb, a packing mechanism, an endless apron for conveying the packed fiber, and a pair of feed-rolls constructed to feed the opened, doffed, and packed fiber to the main ardingcylinder, as described.

3. The combination, in a carding-engine with the main cylinder and a pair of feedrolls adapted to feed the fiber directly to the main cylinder, of mechanism for preparing the fiber, consisting of a pair of feed-rolls for feeding the lap to the licker-in, alieker-in for opening the lap, a carrying-cylinder, and a dottcr-roll for carrying and condensing the fiber, provided with a dotfer-comb, a reciprocating packer mechanism, and acarryingapron, all constructed to open the lap, partially straighten and clean the fiber, collect, condense, and pack the fiber, and deliver the packed fiber to the feed-rolls adjacent the main cylinder, as described.
