T 0 all in item it on 07/ concern:

Be it known that An'rrrUR A. VAeonpL. deceased. late a citizen oi: the United States. and resident of Dallas, in the county of Dallas and State of Texas, did invent new and useful Improvements in Breast Mischa nism tor Fiber-Treating Machines, such as Gins, of which the following is a specification.

This invention relates to the breast-structure, or material -under -treatment supply holder means. of machines such as burring; machines. gins or delinters. I

A principal object of the invention is to provide a holder for the material under treatment by the pickers, disintegrators, gin-saws or like kinetic elements of? the machine which can be taken out of the way conveniently for access to the kinetic element without disturbing adjustments, inter- 'feringr with the op rative parts, or wasting the material; to provide for the adjustable limitation oi the normal operative position of the breast structure; and to provide in an improved way {or motion of the breaststructure to and locking it in inoperative position to cause stoppage of operation of the machine without cessation oimotion of its working parts.

Thev invention will be described with reference to one preferred form of the numerous ways in which. it may be realized as shown in the accompanying drawings, in which Figure 1 shows a vertical central section through a linter gin utilizing the present invention; and

iligure 2 is a similar view showing the parts in another position.

Referring: to Fig. 1, the machine shown comprises the usual saws 10 mounted in spaced series on shaft 2 to constitute a saw cylinder; adofier brush 5 and lint-flue 65, 70, and other parts also correspondingto the disclosure in the application Serial No. 319,105, filed August 22, 1919, of which this application is a division.

It is desirable as usual to provide for the adjustment of the gin-grate 9 in respect to the saws; to provide for temporarily lifting the breast as a whole to take the material in the roll-box out of range of the saws; and in addition it is desirable to provide means for taking; the breast structure 6', 8, 11. 16, out oi? the way in order to inspect or remove the cylinder.

in the usual. practice, the breast is pivoted at the top, for instance by hinging the upp l board 16 to the member 1 In the nesent structure, the breast is pivoted at on short studs sliding in sector slots 82 in brackets 81, which may be integral with or attached to the "front uprights 1. Slots 82 are central on the point of contact oh between board 16 and member 1 when tie breast is in normal position, Fin. 1. Fituds 80 take into bearings 84- attached to the seed-boa 11. the remainder ot the nratesiallor movable. breast being fast to the irOitTCClS 11 and 1-6.

The adjustment of .he operative position of the g ate and the material being operated upon to d and away from the saw shaft ti ected by positioning the pivots SO in th slots for instance by adjusting the l3 754 o in lugs 86 on the brackets 81. i the breast away from the saws, one the pivot studs 80 is provided -ndle and cam 87 rigid there- 2 ed to react with a roll 88 on to r to lift the pivot and the bottom or the breast by mowing pivot 80 outwardly in slot Cam 8? may be provided with a note: totalre over roll 88 at the maximum displacement oi the pivot and breast. Gravity holds the loaded breast when the handle 96 is operated a ainst the member 1 the breast turning about the point 88 as a pivot. 1 a

The whole breast structure is by these arrangements free to be turned about the pivots 80 into the position shown in Fig. 2, in order to remove, clean or sharpen the saws. l liereto'tore much good seed cotton has been wasted by having to dump the contents of the roll-box in the breast whenever the breast is taken of]? to get at the saws. To avoid this, the breast-hopper 17 is preferably provided with a front-board 18 hinged 180 and adapted to turn over and cover the opening into the roll-box. Board 18 may be held in place by any suitable catch. such the spring catches 19 entering holes in the ends of board 18.

In operation, it is often desirable quickly to stop the operative function of a gin, or

other machine of the kind referred to; for lnstance when one of the machines has been discovered to be out of adjustment, or producing a product not up to standard, in which case all the product of a battery of gins, for instance, may be damaged by mixture with the general output of lint from the improperly functioning machine. iVhen such a condition occurs, operation of the handle 96 enables the breast-structure to be withdrawn from operative relation to the saws without stoppage of the motion of a saw cylinder and brush, or of the pneumatic connections. These parts may then be stopped and adjusted; and operation re- .sumed without waste of material or time.

What I claim is:

1. A fiber-treating machine having therein. a breast pivoted at its lower portion, and having means forv shifting the pivotal axis in an arc whose center is adjacent to the upperedge of the breast.

2. A. fiber treating machine having therein a breast'pivoted adjacent to its-bottom edge, means for shifting the pivotal axis in a circular arc, and adjustable stop means engageable with the lower part of the breast for determining the operative position of such pivotal axis.

3. A fiber treating machine having a breast comprising a grate fall, pivot means for supporting the breast structure adjacent to its lower edge, means for permitting the adjustment of such pivot means along an arcuate path having its center substantially at the upper edge of the grate fall and adjustable stop means engageable with the lower part of the breast structure.

4-. A fiber treating machine having therein a breast, pivot studs projecting from opposite sides of the breast adjacent to its lower edge, fixed elements having guideways for the reception of the respective pivot studs, a rotary cam member mounted upon the lower portion of the breast and having,

an actuating handle, and a fixed member engageable with the cam whereby upon rotation of the cam said pivot studs are caused to move along their respective guideways. I

5. A fiber treating machine having a breast provided with bearings at either side thereof adjacent to its lower edge, pivot studs engaging the respective bearings, fixed brackets having arcuate slots into which the respective studs extend, a cam connected with one of said studs, said cam havin a notch in its peripheral edge, a handleror turning said cam, and a fixed stud for engagement with the edge of the cam, move ment of the handle serving first to move the pivot studs along the slots whereby to adjust the breast to inoperative position and thereafter by engagement of the notch with the pivot stud serving to retain the parts in such position. V

6. A fiber-treating machine having therein a breast pivoted at its lower portion and free to be swung forward at the top, incombination with means for stopping the opening at the top of the breast to prevent spilling its contents when swung forward.

7. A fiber treating machine having a breast structure and fiber manipulating devices, means for pivotally supporting the breast structure at a point adjacent to its lower edge whereby to permit it to be swung forwardly and-downwardly away from the fiber manipulating devices, a cover for the feed opening at the top of the breast and means for locking such cover in closed position.

8. A fiber treating machine having. a

breast structure, means for pivotally supporting such breast structure adjacent to its lower edge, a cover for the feed opening at the top of the breast structure hinged to the upper part of the latter, and a spring catch for retaining such cover in closed position.

Signed by me at Dallas, Texas, this 10th day of November, 1920.
