4 Claims.

This invention relates to removable brush covers for cotton linters.

One object of the invention is to provide, in a cotton linter or machine of similar character for the treatment or processing of cotton, a conveniently located and quickly and easily removable and replaceable cover for the rotary brush element thereof, whereby access to the brush element is readily gained when occasion requires, for adjustments, repairs, etc.

Another object of the invention is to provide a simple yet practical and efficient hood-like cover which permits the lowering of the supporting frame and housing portion of the machine in the region of the brush element to a plane below the upper working portion of the brush element, whereby, upon removal of the cover, not only said element itself is exposed and conveniently accessible for adjusting and repairing it, if nec- 0 essary, without necessitating its removal from its normal mounting in the machine, but access is also readily gained to every part of the working chamber in which the brush element is located.

A further object is to simplify the releasable fastening means for the removable cover without taking from the requisite stability of the structure.

A construction designed to carry out the invention will be hereinafter described, together with other features of the invention.

The invention will be more readily understood from a reading of the following specification and by reference to the accompanying drawing, in which an example of the invention is shown, and 5 wherein:

Figure 1 is a fragmentary side elevational View of a cotton linter in the region of the brush element, showing a cover applied in accordance with the invention;

Figure 2 is a transverse, vertical section showing the working relation between the brush element and cover when the latter is placed on the machine;

Figure 3 is a fragmentary perspective view of 45 one end portion of the cover detached; and

Figure 4 is a fragmentary section, on a somewhat enlarged scale, taken on or about the line 4-5 of Figure 1, to show details of the cover and more particularly the fastening means therefor.

Refering now to the drawing, the numeral l designates the rear portion of a cotton linter machine in the region of the brush element 2, which latter is located in the working chamber 3 of the machine. The brush element 2 is con- 55 ventionally shown as mounted on the usual shaft 4 which is journaled in bearings 5 provided therefor on the side frame members or housing walls of the machine. For the purposes of the present invention, the side frame members or housing walls of the machine are lowered, as at 6, to a horizontal plane preferably just above the axis of the shaft 4, as shown, or substantially even with the upper side of the shaft; and, to permit of readily placing and removing the brush element 2, the side frame or wall members are cut away or notched, as at l, in order to provide working clearance as well as for the ready replacement and removal of the shaft 4.

At the rear side of the machine frame or housing is a horizontal cross frame member 8, which, as shown, may be of angle iron cross section or substantially inverted L-shape. As shown more clearly in Figure l, the end portions of said frame member 8 are supported on counterpart seat portions 9 of the side frame or housing members of the machine and, obviously, there secured by welding or other approved or desirable means of fastening, for example, screws, bolts or rivets. The means of fastening of these, and other structural parts, however, does not enter per se into the present invention. Hence, the same is not shown in detail in the accompanying illustrative drawing.

Extending up from the cross frame member 8 are bracket frame members In having foot portions ll of angular form corresponding to said frame member 8 on which they are securely fastened by any approved means, said bracket frame members extending, as shown at l2 in Figure 1, horizontally with their upper portions projected towards the upper frame or housing portion I3 of the machine, to which they are joined, as at It. The bracket frame members l0 brace the upper rear portion of the machine body frame or housing, and at the same time ample space is afforded between said members l0 themselves and between them and the adjacent body frame and housing side wall members for readily placing and removing the brush cover l5, now to be described, and facilitating accessibility to the brush element when uncovered and also to the interior of the working chamber in which the brush element is located.

The cover 15, which, obviously, may be conveniently made of sheet metal, comprises the end walls It, said end walls, as shown, consisting of body plates reinforced at their marginal portions by angle members l'l, affording stiffening flanges thereabout.

Preferably, the rear upper portions of the end walls P3 are rounded, as at l8, and a top plate I9 is secured marginally, as at 29, to the reinforced flat upper and rounded rear marginal portions of said end walls It, thereby producing a relatively light-weight yet rigid and stable hood-like structure to cover, when applied, the portion of the brush element that protrudes above the lowered body frame or housing side wall portion 6 of the machine.

The cover l5, when applied, as shown, rests at each end on said horizontal machine frame or body portions 6 with the inner vertical edge portions of the end walls i6 abutting the adjacent portions 2'2 of the machine frame or housing exending vertically upward from said horizontal portions 6, and to afford clearance for the brush shaft bearing 5 the horizontal flange portions of the cover end walls are cut away, as at 23 (see Figures 1 and 3).

The lower outer end portion of the cover i5 is placed between the foot portions l l of the bracket frame members til, so that the cover is held against shifting movement transversely of the machine body frame or longitudinally with respect the axis of the brush element. To further prevent shifting of the cover 15, more particularly in a transverse direction, or, in other words, in a direction outwardly from its normal abutting relation to the vertical portions 23 of the body frame or housing of the machine, and also to prevent accidental or unintentional lifting the cover, releasable fastening means is provided at each end of the cover. As shown, this fastening means comprises an ear or lug 2.5, rivetwelded or otherwise secured or provided on the end wall bottom reinforcing member I! near the outer side of the cover (see Figures 1, 3, and i), said ear or lug 24 having a transverse openended slot 25 to releasably engage a securing bolt that is applied therethrough and through an aperture obviously provided therefor in a horizontal flanged inward extension or shelf-like ledge El of the seat portion 9 of the body frame or housing side wall of the machine where the foot portion i i of the br cket frame member It rests. By this provision the cover is obviously fastened in place by tightening the bolt 26 to clamp the ear or lug 26 upon said flanged extension or ledge 21, yet the cover is readily removable by merely loosening the bolt 26 and moving the cover outwardly and thereby withdrawing the slotted ear or lug member 24 from ongagement with the bolt, it being, of course, understood that a similar fastening means is provided at opposite ends of the cover.

In order to further reinforce the cover l5 which, of course, to accommodate the brush element, is open at its bottom and inner side, and particularly to strengthen and make more rigid the outer lower marginal portion thereof, an angle bar or flange element 28 is preferably secured thereto on the outside, as shown.

Cbviously, the structure and particular arrangements of the parts of the device relative to each other and in each particular adaptation of the invention in practice may be modified in many respects within the scope of the appended chums. The invention as defined, therefore, is

not limited to the specific construction and arrangement of the accompanying illustrative drawing.

What I claim and desire to secure by Letters Patent, is:

1. In a cotton linter or the like, in combination with the body frame and housing parts of the machine assembly, a portion of which constitutes an open-topped brush chamber proper, the opposite end walls and the outer transverse wall of the chamber being lowered relatively to the general casing of the machine, a brush element located and operating in the chamber, the upper portion of the brush being above the open top of the chamber proper, and a hood-like cover entirely detachable and removably mountable to close the open top of the chamber proper and complete the continuity of the chamber above the brush element.

2. In a cotton linter or the like, in combination with the body frame and housing parts of the machine assembly, a portion of which is of relatively lowered elevation with respect to other correiated portions thereof, said lowered portion containing and defining the brush chamber proper, said chamber proper being open-topped, a brush element located and operating in said chamber proper, and an entirely detachable and removable cover closing the open top of said brush chamber proper and completing the continuity of the chamber to an elevation above the open top thereof.
