SPECIFICATION formingpart of Letters Patent No. 523,832, dated July 31, 1894.

' Application fi August 19,1893; Serial No. 483,538; (No model.)

To aZZ whom it may concern.-

Be'it known that I, J OEtN- OROMIE, a citizen of the United States, residing at Camden, in the-county of Camden and State of New thereof and to means adapted to engage and disengage adoffer-roll to control the relative speed of thes'aid doffer roll with respect to the doffer-cylinder and independent movements of the rub-apron mechanism of the'machine.

Hitherto many objectionable features have been presented in the working of condenser or finisher carding machines and among them may be mentioned first, the difficulty in keeping the rub-mechanism in frictional contact and under proper tension and to insure a freedom of rotary as well as reciprocating motion to obtain at all times a good rubbing action upon the sliver or slubbing to be transformed into roving; and second, the difficulty of in-' creasing or decreasing at will the rate of speed of the doffer-roll with respect to the doffercylinder in order to insure efiective action on thesliver or slubbing preparatory to its treatment by the rub-mechanism to transform the same into roving, withoutdisorganizing the machine with its attended labor, time and expense.

The principal objects of my present invention are first, to overcome the above mentioned disadvantageous features and to provide a comparatively simple, durable and efficient condenser or finisher carding machine having adjustable rub-apron mechanism arranged so as to compensate for wear, Warping and stretching or slackening thereof and mechanism adapted to be connected with the doffer-roll and the doffer-cylinder of the machine so as to vary relatively the rate of speed of\ said roll with respect to said cylinder, whereby is permitted the treatment of either coarse or fine fibrous material; and second, to provide a condenser or finisher carding machine with a gear-mechanism interposed between the doffer-cylinder and the doffer-roll and adapted to be brought into engagement therewith to increase or decrease the speed of rotation of said roll with respect to said cylinder independently of the movements of the rub-apron mechanism of the machine.

My invention consists of the improvements ina condenser or finisher carding machine hereinafter described and claimed.

The nature and general features of my invention will be more fully understood from the following-description taken in connection with the accompanying drawings forming part hereof; and in Which- Figure 1, is aperspect-ive view of the rub apron mechanism of my invention, the said view being taken from the eccentric sidev of the machine and showing in detail the construction and arrangement of the mechanism of the rub-aprons; and Fig. 2, is a similar view of the rub-apron mechanism, the doffercylinder, doffer-roll, and also means adapted to engage and disengage said doffer roll to permit of the rotation of said roll from said cylinder and also to permit of the changing of the speed of said rollwith respect to said cylinder independently of said rub-apron mechanism embodying features of my invention, the said view being taken from the gearside of the machine.

Referring to the drawings A and A, are the end standards of the machine of any suitable construction provided with upper and lower cross-frames A and A suitably bolted thereto on the respective sides of the machine for supporting certain mechanisms of my invention to be hereinafter fully described.

B, is the dofier cylinder mounted on and keyed or otherwise secured to a shaft 1), which is provided with a gear-wheel B. It should be borne in mind that twoof such cylinders are'employed, as illustrated in Figs. 1 and 2.

B is a movable arm mounted on the shaft b, adjacent to the gear-wheel B, as illustrated in Fig. 2, and carrying at its free extremity a gear-wheel B which is suitably journaled c and 0 are hangers depending from the frames A and A on both sides of the machine and provided with oblong slots 0 and 0 for the reception of the ends of the shaft 0, of the doffer-roll O.

The dofiEer-roll C, may be removed from the slotted hangers depending from the frames A and A by the release of the movable arm 13 from its engagement with the slotted yokes a, formed integral with or secured to the standard A, as illustrated in Fig. 2, by loosening the tightening device 0 to cause said movable arm with its gear B to be disengaged from the gear 0', of the doffer roll 0, and without interfering with the dotfer cylinder 13,01- disorganizing the rub-motion mechanism of the machine. In a word, the gear-wheel B as arranged may be readily caused to engage or to be disengaged from the gear 0, of the doffer-roll C, in order that the relative rate of speed of the doffer-roll with respect to the doffer cylinder may be varied by removingthe doffer-roll and applyinga larger or smaller gear 0, to the shaft 0, as requirements may demand.

B are gear-wheels mounted on one end of each of the dofler cylinder shafts b, as shown in Fig. 2, and interposed between these wheels and meshing therewith is a gear B which is mounted on a shaft 13, carrying a pulley B, at the free extremity thereof and adapted to be engaged by a belt, not shown, for rotating said pulley, thereby imparting through the gear B rotary motion to the upper and lower gear-wheels B, for a purpose to be presently more fully explained.

I, represents a gear mechanism for controlling the rotation of the rub-apron mechanism from the positively actuated gears of the dotfer cylinder and comprises a train of gear wheels t', t, 11 i and t'flarrangedand adapted for operation in the manner indicated by the arrows in Figs. 2. The upper train of gears being the same as the lower train, both have been designated by the same reference letters. The gear-wheel 1 is mounted on a shaft 2', which is journaled to and supported from ahangert depending from the lower end frame A of the machine; and carries a pulley i for the reception of a belt adapted to impart motion to a winding frame mechanism, not shown, because forming no part of my present invention. Certain of the gears, namely i and 1' are applied to the end journals of the tightening rolls of the rub-apron mechanism of the machine, as clearly illustrated in Fig. 2. 1

It may be here remarked that the gear mechanism herein-above mentioned forms no part of my present invention, but has been shown simply as a well known means of imparting rotary motion to the dolfer-cylinders .and rub-apron mechanism. of the machine, which embody the characteristic features of my invention.

D and D, are top and bottom rub-aprons,

which are respectively held under proper ten sion lengthwise by means of end tightening rolls 6 and 6', provided with end journals 6 and 0 extending through bushings or boxes (L and a in loose engagement with hearing blocks 71 and h, connected with the top and bottom cross-frames A and A as clearly shown in the drawings. The bushings or boxes a and a extend along the journals 9 and 6 until they engage the said bearing yokes to permit of the reciprocation thereof.

The rub-aprons D and D, are held in frictional contact with one another by means of intermediate rolls provided with end journals e and 6 which are held in top and bottom bushings, boxes or bearings e and 6 The two series of bearing blocksh, on therespective sides of the machine are provided with hearing posts 72. for the reception of vertically and longitudinally disposed screwbolts 7L3 and h, With tightening nuts 7L5, working in ways 71 provided in the cross-frames A and A and engaging back-stops 72 and lugs h, cast preferably with the respective cross-frames. In the ways 72?, the screwbolts 7L are afforded a range of movement. The threaded screw-bolts 7L and 7L4 respectively engage the series of back stops it and lugs 71. in order to permit of the adj ustment of the respective rolls of the top and bottom aprons so as to maintain the latter un der proper tension lengthwise and in frictional contact with each other. The lower bearing blocks h, on the gear side of the machine as shown Fig. 2,are provided with complemental longitudinal arms h and h, with lugs 71 and It, one of which is provided with a threaded aperture h", for the reception of a screw-bolt h The arms 71 and h, engage the bottom of the frames A which form seats therefor. The lugs 72, and 7L engaged by the screwbolt h, are arranged so as to permit of the tightening or loosening of the lower bearing blocks h, suitably connected with the journals of the lower tightening rolls of the rubaprons for maintaining the respective aprons under the proper longitudinal tension.

On the eccentric side of the machine as clearly illustrated in Fig. 1, the respective journals e and a of the tightening rolls e and e, of the rub-aprons D and D, are extended beyond the bearing blocks 7t and 71., and engage with the end oblong slotted yokesf and f, of spanning frames F and F. 'These frames are provided with projecting studs or pins and f for engaging the straps g and g, of eccentrics G and G, which are suitably journaled to a vertical shaft G the shaft G being held in the bearings 01. and 0. of brackets or arms A and A, secured at the top and bottom of the end standard A.

nals of the intermediate rolls of the rubaprons on the eccentric side of the machine, as shown in Fig. l are mounted sleeves q and 9 provided with slotted lugs or projections g and g engaging by means of pins or bolts To the jour- 9 the Slotted lugs or projections g and 9 formed integral with the spanning frames F and F, these sleeves, projections, &c.,-being shown in Fig. 1, in connection with only a part of the intermediate rolls for the sake of greater clearness.

The ends of the respective journals e 6 e.

and 6 of the tightening rolls are provided with end Washers e and with nuts e, on the eccentric side of the machine for preventing end displacement of the same in connection going explanation, it will be observed that the end journals of the said tightening and intermediate rolls are attached to the said spanning frames F and F, in such manner as to prevent endwise movement independently of said frame, although permitted to rotate in their connection therewith and in the manner hereinbefore fully described.

It will be observed by reference to Fig. 1, that the end bearing yokes fand f, of the spanning frames F and F, are provided with oblong longitudinal slots, while the interme-.

diate bearing yokes f and f are provided with vertical oblong slots in order that the journals e e 6 and e, of the respective rollsmay be properly adjusted in the said yokes.

By the hereinbefore described arrangement of the respective aprons D and D, they are maintained firmly in contact with each other, so that the sliver or slubbing in passing be. tween them through the rotary and reciproeating motions given thereto is formed into roving and delivered therefrom.

The operation of the machine for the transforming of the sliver or slubbing into roving, is as followsz-The fibrous material is fed from the doffer-cylinders B, and passes to the dotfer 4 rolls 0, and then to the respective aprons D and D, rotating in the direction of the arrows, as indicated in Figs. 1 and'2, and

by the actuation of the eccentrics for imparting reciprocating motions to said aprons, the sliver or slubbing is formed into roving and discharged from the aprons for subsequent treatment or use.
