DRAWING-FRAME ROLLER.

Application filed February 26, 1924. Serial No. 695,169.

To all whom it may concern:

Be it known that I, LUKE DUNKERLEY, a subject of the King of Great Britain, a resident of Oldham, in the county of Lancaster, England, have invented new and useful Improvements in Drawing-Frame Rollers, of which the following is a specification.

The invention relates to improvements in or relating to machines for treating'cotton and the like and has for its object to provide a light but strong wooden roller for use in such machines but the invention is more particularly applicable as a light stripping roller for the stripping of cylinders and dofi'ers of carding engines.

It is customary to build up such rollers of a number of pieces of wood which are suitable clamped together to form the roller, and this construction tends to make the roller heavy and not easily portable.

Now according to the present invent-ion the roller is constructed of a single solid piece of wood which is suitably hollowed out thus providing a roller of comparatively light weight and which can be conveniently removed or interchanged as desired.

The invention will now be more fully described with reference to the accompanying drawings in which Figure 1 is a longitudinal View in section of a roller constructed according to the present invention mounted upon its shaft and Figure 2 is an end View thereof.

Referring to said drawings-1 represents the roller which is formed out of a single solid piece of suitable wood which is hollowed out in any suitable manner from each end thereof, a short portion of its length at or near the centre being left solid in order to provide a strengthening disc or support 2 to prevent the roller 1 from collapsing or sagging when subjected to a heavy load and the ends of the roller 1 are filled in with end pieces or discs 3 which serve the same purpose as the disc or support 2 as ,bove explained.

The discs or supports 2 and 3 are provided' with holes or perforations 4 in the centre thereof through which is fitted the shaft 5 on to which the roller 1 is fixed by means of studs or pins 6 which are passed diametrically through the ends of the roller 1, the end pieces or discs 3 and the shaft 5 and if desired similarly through the centre disc 2.

In order to prevent the ends of the roller from becoming worn by contact with an ad jacent bearing bracket or the like I provide a metal disc 7 upon the shaft 5 fixed to the end of the roller 1. r

I may employ any number of strengthening discs upon the shaft 5 within the roller 1 and said strengthening discs may be inserted from'either'end and secured to the roller 1 and shaft 5 in a similar manner to that hereinbefore described.

It will be understood that the roller 1 and reinforcing discs 3 may be secured to the shaft 5 in any manner otherthan thatabove described and that the details of construc-' tion of the device may be further modified without departing from the principle of the invention.

What I claim as my invention and desire to secure by Letters Patent is A device of the character described, com

prising an integral wooden, roliler bored from opposite ends thereof to points at opposite sides of the center of its length there by to form a central disk integral with the roller, disks secured in the opposite ends of said roller, each of said disks being provided with a central axially extending opening, and a shaft extending through said openings and secured to each of said end disks, said shaft extending beyond the roller at both ends thereof thereby to provide bearing portions for the roller. 7

In testimony whereof I have signed my name to this specification.

' LUKE DUNKERLEY.
