CARDING-ENGINE.

SPECIFICATION forming part of Letters Patent No. 361,815, dated April 26, 1887.

Application filed August 19, 1886. Serial No. 31.245, (No model.)

To all whom, it may concern,.-

Be it known that we, BENJAMIN ALFRED DoBsoN and WILLIAM Isnnnwoon BROMI- LEY, of Bolton, in the county of Lancaster,

England, have invented new and useful Improvements in Oarding-Engines, of which the 'ollowing is a full, clear, and exact descrip- Our invention relates to improvements in 1o that class of carding-engines in which revolving dats travel upon flexible bends; and the object of our invention is, r'st, to provide improved means whereby the iiexible bends, one or both, may be adj usted separately or simulx5 taneously, so as to insure amore uniform and accurate adjustment of the dats relatively to the main cylinder of the machine, and, secondly, to provide an arrangement for automatically adjusting the front and rear carrier shafts or rollers, around which the flats pass when the flexible bends are adjusted', so that the dats may be accurately adjusted at all points with reference to the main cylinder.

The invention consists in the construction,

combination, and arrangement of parts and details, as hereinafter fully described, and pointed out particularly in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,

in which similar letters of reference indicate corresponding parts in all the iigures.

Figure lis aside elevation of a cardingen gine in part provided with my improved mechanism for adjusting the flexible bends.

Fig. 2 is a cross-section taken on the line A A, Fig. 1. Fig. 3 is a side elevation showing the mechanism for adj usting the exible bends and the dial for indicating the adjustment. Fig. 4 is a plan view of the same, the engine- 40 bends being in section and part of the main cylinder being broken out. Fig. 5 is a View similar to Fig. l, but illustrating the mechanism whereby the carriershafts are adjusted simultaneously with the flexible bends. Figs.

6, 7, and 8 are detail views showing the arrangement of the adjustable rear, center, or carrier shaft, and Figs. 9 and 10 serve to illustrate the arrangement of the adjustable front, center,or carrier shaft.

a designates the main cylinder of the card- 5o ing-engine, and I) b the engine-bends. Each flexible bend c is connected at one end to the engine-bend Z) by a pivoted link, d, and at its other end the flexible bend is provided with a pin, stud, 0r projection, c?, which runs on the ou rved or inclined cam edge g of a slot formed in a bracket, g, bolted or otherwise secured to the bend b. At several points on its length each flexible bend c is also provided with pins, studs, or projections c', which run onY the curved or inclined cam edges e of brackets e, secured to the engine-bend by bolts f,or formed integrally with the bend. The inner side of the rear end of each flexible bend c is formed or provided with rack-teeth 03 with which engages a pinion, h, fixed on a stud or short shaft, h. The shaft h is mounted to turn, as shown in detail in Figs. 6, 7, and 8, in a boss or bearing, t', formed on the inner side of. the end of a bracket, i, and also in said bracket, which carries at its upper end the worm mechanism for turning the shaft h', as hereinafter described. v Y

The boss or bearing t" is received in an aperture formed in a link or block, o, mounted to slide within the grooved and slotted bracketpiece p, secured to tlie-engine-bend b by bolts f, as best shown in Fig. 5, and to the sliding block o the end of the bracket t' is rigidly attached by bolts i2, as shown in Fig. 6.

The pin c2, fixed on the end of the flexible bend c, besides passing through the slot in the bracket g, also rides in a transverse slot, o', formed in the sliding block `o, as shown in Figs. 6 and 8, and clearly indicated in Fig. 5. Vith this construction,when the flexible bends o are to be set for adjusting the iats relatively to the main cylinder a, the short shafts 71, are rotated, as hereinafter described, causing the bends c to move lengthwise, owing to the engagement of the spur-wheels h with the rackteeth c3 on the bends c. Then, owing to the properly adjusting the flats traveling on the. rflexible bends c.

The pins c2 on the iiexible bends ride in the slots o of the sliding blocks o,which carry the shafts h', and thus cause thesaid blocks o to be moved outward or inward with the bends c, so that the spur-wheels h are held continually in engagement with the rack-teeth c3 on the liexible bends when the same are being adjusted.

For accurately adjusting the bends I provide the short shafts h with worm mechanism for turning them, as shown in Figs. 3 and 4.

As therein illustrated, a large worm-wheel, j, is fixed upon the outer end of each shaft h and is in gear with avworm, k, mounted on a shaft, 7c', which is journaled in a suitable bearing fixed or formed upon the movable bracket z'. The outer end of either worm-shaft k also carries a worm-wheel, k2, with which are in gear wormsZ on the ends of a transverse shaft, Z', extending across the engine and journaled near its ends in bearings fixed or formed upon the movable brackets z' on either engine-bend b. Thus by turning the shaft Z the flexible bends c on either side of the cylinder a can be adjusted simultaneously, or, if desired, by disconnecting said shafts Z the bends c may be adjusted independently of each other. For indicating the amount of such adjustment, I provide the outer face of the large wormwheels j-one or both, according as they are connected or not-with circular scales j', with which register pointers or indices jz, attached to the bearings of the worm-shafts k or other suitable supports.

The end of the shaft Z is squared toreceive a key for turning it; and for locking the shaft in position after adjustment I provide a slotted locking-piece,v m2, pivoted to a suitable support on the movable bracket z' and arranged to swing so that its slot will engage the squared stem of the shaft Z and prevent it from being turned. An ordinary padlock, m, can then be passed through eyes m', formed on the locking-piece m2 and in an adjacent fixed support, so that unauthorized persons are prevented from tampering with the adjustment of the flats.

In order that the front and rear rollers, carrying the Hats, may be adj usted simultaneously with the flexible bends c, I mount their respective shafts n3 and n', as shown in Figs. 5 to l0, in bearings formed on the outer ends of the sliding blocks o, before referred to, and similar sliding blocks, q, guided in the bracketpieces s, which are secured to the enginebends b by bolts f. Each sliding block g is operated from the liexible bend c, similarly to the block o, by a pin or stud, 0*, on that end of the bend c riding in a slot,.q, formed in the said block. The sliding blocks o and q on both engine-bends being moved outward simultaneously with the flexible bends c, the shafts n n3 of the carrying-rollers are adj usted coincidently therewith, so that the ats will be set at a proper distance from the main cylinder ct at all points on theirlength, the worm mechanism aiding in the accurate adjustment of the movable parts.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
