Application filed August 9, 1926. SerialNo. 128,062.

This invention relates to means for mounting and adjusting the worker and stripper rolls of a carding machine in proper relation to the card cylinder.

In this type of carding machine, well known and familiar to one skilled in this art, the card cylinder is partially surrounded by a plurality of units each comprising a worker roll and a stripper roll. The number of these units varies and it is frequently desirable to be able to-change the number of units employed on a given machine.

One object of the present invention is to provide a simple and efficient means whereby, either in'the assembling of themachine or as required inthe subsequent use of the machine, any required number of worker and stripper roll units may readily be mounted in the machine. l

A further object of theinvention-is to provide apair of bearing units for each worker and stripper roll unit together with means for securing each such bearing unit in circumferentially adjustable position on the corresponding side arch of the carding machine, thus enabling any required number of worker and stripper roll units to be employed. a

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed outin the claims. 7

The drawings illustrate so much of an ordinary type of carding machine as is necessary to a disclosure of the present invention together with a preferred form of construction embodying the said invention.

In the drawings V I Fig. 1 is a side elevation, chiefly diagrammatic, of the carding machine.

Fig. 2 is a view in side elevation of a section of one of the side arches illustrating one bearing unit for one unit of worker and stripper rolls embodying the invention.

Fig. 3 is a view-in cross section taken on the line 33 of Fig. 2. I

Fig. 4 is a view in cross section taken on the line 44: of Fig. 2. I

Fig. 5 is a view in cross section taken 'on theline 5-5 of-Fig. 2. a

An ordinary type of carding machine is shown diagrammatically in Fig. 1 having at.

each'side a side, frame 1 supporting a side arch 2. The main card cylinder 3 is journalled on an axis 4 in theside arches. This cylinder is partially. surrounded by a plurality of worker and stripper roll units, the worker rolls being indicated. at 5 and "the' stripper rolls at The outer peripheral face of each side arch 1s preferably ground or finished off to present a plurality of fiat faced concentric ribs'7. Between two of these ribs a. T shaped slot 8 is formed extending also concentrically of the side arch.

As the construction of the worker and stripper roll journals, the bearing units therefor and the means for adjustably mounting-the bearing units and foradjust ing the respective journal bearings is preferably the same on both sides of the machine and the same for each unit, it is only necessary toillustrate and describe the construction for one unit.

Each bearing unit is shown as comprising a somewhat trapezoidal shaped base I plate 9 adapted to'seat against the faces of the ribs 7, and preferably provided with a flange 10 overlying the periphery of the side arch. This base plate is provided with one or more bolts, herein shown as two by means of which it-is securedin circumferentially adjustable position to the side arch. In the construction illustrated these bolts 11 have their heads 12 seated in the T shaped slot 8 and their stems passing through the base plate an dtheir threadedends provided with the nuts 13. Thus it will be seen that each base plate is readily positioned and locked or securedinadjusted position of any desired point circumferentially of the side arch. While the T-shaped slot is disclosed as extending throughout the face of the arch,

the important feature is that it extends throughout the entire segment of the arch face where the worker and stripper rolls are positioned. Thus in assembling the machine any desired number of worker roll and stripper roll units may be provided and furthermore the number of such units may required by readily be changed whenever This standany given set of conditions.

ardizes the side arch construction and the.

construction of the units thus economizing in the manufacture of the machines. Thls also gives great flexibility tothe machine in the hands of the user enabling it to meet varying conditions of use.

In the preferred construction illustrated the base plate 9 at one side is provided with parallel ribs M-eXtending parallel to a radius of the side arch. These ribs constitute a guide way. A bearing block 15, recessed from its inner surface at 16 is mounted to slide, on the guide way formed by the ribs 14, radially of the arch. This bearing block at its upper end, carries the journal. bearing for a worker roll 5. As illustrated'the hearing block,- fo .,tl1is purpose, is formed. into a semi-circular seat 17 in which rests the journal sleeve 18 in which in turn is mounted the journal 19 of the workerroll. Beneath the bearing block a lug20 projects integrally from the base plate 9. A screw 21 passes through the aperture iuthis lug and is threaded into the bearing bloclrand is provided with nuts 22 above and below the lugs20. It will thus be seen that by turning the nuts 22 the bearing block may he slid radially on the guide wayl thus to adjust the journal bearing of the worker roll accurately toward and from the card cylinder but without changing its position cireunrl'erentially of the card cylinder and arch.

A bolt 23 isalso provided at the upper end of the: base plate passing through a radial slot 2a in the bearing block 15 and provided at its outer end with a washer 25,. and a nut 26. Thisbolt, as well as the two nuts 22 provide means for locking the bearing block firmly in its adjusted position.

A second bearing block 01' generally similar construction. to thatalready described is provided for the journal bearing 28 of the journal 29 of the stripper roll 6. This bearing-block is seated, upon flat ribs 30. on the base plate. Beneath this bearing block the base plate is provided with anotherintegrally projecting lug 31 and a screw 32. passes through an aperture in this lug, and is threaded into the lower end of the bearing block 27 and is provided with nuts 33above and below the lug. Thus it will be seen that the bearing block 27 is also adjustable, by a similar means to that already described in aradial directions.

Near its upper edge the base plate 9 is provided with a projecting lug 34 centrally of the ribs 30. Screws 35 are threaded through the side walls of the bearing block 27 and; abut thislug 34-. Consequently by adjusting these set. screws the upper end of the. bearing block .27 may be adjusted ,circumt'erentiallyot theareh. This adjustment is comparatively slight andmay readily be made by looseningithe nuts 33 slightly. This bearing block is also locked in adjusted position not only by theset screws 35 andthe nuts 33 but by a bolt 36 passing through the base plate and passing through an opening 3? inthe bearing block and having at the face 01"- the bearing block a washer 38 and nut 39.

It will be seen that the bearing block for the stripper roll journal is adjustedboth radially and circumi erentially on the base plate and is readily locked in any adjusted position.

When therefore, after the grinding of the worker and stripper rolls, it becomes necessary to readjust the positioiiot these rolls to correct for the grinding operation, it willbe seen then that the adjustment provided for the bearing block and theworker roll insures that the axis of the worker roll will alwaysremain in the plane: of theaxisof the card cylinder while the distance between the surfaces oi the worker roll and card cylinder-will be accurately .determinedby this adjustn'ient, while the adjustment provided tor the stripper roll enables each journal of the stripper roll to be adjustedtoward and from either orboth of the surfaces of the card cylinderand workerroll to piace the stripper roll in the required cooperative relation withboth.

Having thus described the invention, what by Letters Patent, is:

LA carding machine comprisinga frame having side arches, a card cylinder journalled in the frame between the arches, a plurality of roll units co-operating with the cylinder in the ca-rdingoperation and each is claimed as new, and desired to be secured loo comprising a worker roll and a stripperroll,

plate radially of the arch and; a journal bearing for the stripper-roll adjustable on the base plate radially and circumferentially of the arch. l

2. A carding machine comp-rising a frame having side arches a card cylinder .journalled in the frame; between the ,arches, a y

plurality of roll units cooperating with the cylinder in the carding operation and each comprising a worker roll and stripper-roll, a pair of bearing units toreach 'roll'unit, each bearing unit comprising a base plate seated against the corresponding sidearch face, each side arch having a circumferential way on its face in the formof a: T shaped groove extending continuously around the arch concentric With the axis of the card cylinder, and a bolt passing through each base plate With its head located in the corresponding T shaped groove for rigidly securing the base plate seated against the side arch at any desired circumferential position, each bearing unit comprising a journal hearing for the Worker roll adjustable on the base plate radially of the arch and a journal bearing for the stripper roll adjust- 10 able on the base plate radially and circumferentially of the arch.

In testimony whereof, I have signedmy name to this specification.
