Application filed June 8,
My improvement relates more particularly .to the class of detaching' 'rolls described in Letters Patent of the United States, No. 1,546,763, granted to HQTunstall July '21, 1925. V v I Heretofore top detaching-rolls such as are described in saidipatent have rotated at each end within a bushing or sleeve the *fixing of the machine, the bearings are caused torest on the shoulder or periphery of the larger part of the bushing instead of on the smaller diameter thereof, so'that the shoulder does not bear against the bearing and so that the bearing does not-rest firmly on the bushing thereby permitting the roll to move endwise out of its proper place or the bushing to escape from the insecure grip of the hearing or the roll or bushing or both to drop down into the machine and hence prevent its proper working. 7
As shown in said patent, the bearings are mounted on springs 94: or, as is quite usual on a weighted lever which is given a proper detaching movement, preferably about the axis of roll 87 as in that patent. 7 My improvement is intended to overcome these troubles, and it consists, generally speaking, in eliminating the shoulders and in providing means other than the shoulders for holding the top roll from moving endwise. Thus instead of reducing the diameter of a portion of the bushing to form a shoulder, I provide a bushing or sleeve of proper uniform outside diameter and of suitable length and properly shaped on its interior to fit on each end of the roll, within which'the roll may rotate and upon which the hearing will rest. Thus, it"is more or less immaterial exactly where the bearing strikes the bushing. The shoulder having been eliminated by this construction, I have provided a stop wall at each end of each roll so that the roll may butt against it and the roll will have no possibility of any sub- V BEARING non ror-nE'raeH ne-noms.

stantial endwise play, andT also close the space at'the side "of the lower roll so that the top roll may not fall through into the machine, all asdescribed below:
My invention will beiunder'stoodby reference'tothe'drawings where it is shown'in' its preferred form.
- "Figure 1 is a plan of a top roll mounting,
showing only the-"forks' 14,'while attached 'I to the lever l l0 as shown in Fig. 2'."
Fig; 2 is a crossfsectionitaken through.
the rolls of Fig. 1, showing means for "sup- V and bottom rolls and omitting any detail of thebottom rolls.
1 1s a portion of the frame of the ma 'chine whi'ch supports a casting 2 within which the bottom' rolls 4 are supported.
The casting 2 has mounted upon it'a plate 15, which is bolted thereto by bolts and nuts" '6,--and is not ,further described as it forms" 'no part of my; invention; It'is also. provided with recesses 7 between the portions 11; in
which lie the front top rolls 8 which rest on :the bottom rolls 4: (see Fig. 2). It is provided also with arms 9 which have lateral extensions 10 running parallel with the axis of the'top roll, the side wall 120 of which comes close enough to the corresponding bottom roll to prevent the top roll from falling down into the mechanism below it, if in setting, it should not be held by the bearing.
See Fig. 2 where it will be noted that the space between the loweredge of the part 120 and the lower roll 4 is not suflicient to allow the-roll 8 to fall down'into the machine. It will be understood that there are aseries of these detaching rolls extending the length of the machine and located in usual relation to the several nipper frames. Sleeves or bushings 12 fit onto the ends of each topdetachingroll so'that the rolls may turn therein, these sleeves being of somewhat large peripheral diam-. eter, approximately that of the diam-- eter ofthe body of the detaching roll, and it will be noted from Fig. 1 that these sleeves are engaged by the forks 14 on the end of .the levers 140 which corresponds with the spring v in, said patent. The ends of the detaching rolls themselves abut against the surface 13 of the casting 2 so that they can have no endwise motion. They are,- however, preferably given an oscillating motion as described in the said patent, about the lower roll, because they lie in the bearing forks 14 of the arms 140 (see Fig. '2), these arms 140 being given a swing like the arm 97 of the said patent in any desired way. This bearing 14, however, 7
"beoause'of the construction of the sleeve 12 which is of uniform diameter throughout,
may bear upon any portion of the sleeve" Without in any way disarranging the operation of the machine, and as the ends of the top roll abut the side Wall 13 of the casting,
"the top roll will be held in 'place without any shoulder, as above described.
' 'Thefront' top roll-although shown in the bearings is not particularlydescribed as it vmay be of any usual construction and mounted inany usual way. As shown, it
has. bushings 12 corresponding with the bushin s on the top rolls.
'It will be seen that the top detaching roll in each case turns freely in its sleeve or bushing and is held against its bottom roll by its bearing, the bottom rolls being mounted to turn in thecasting 2 as usual. The interior of the bushings 0r sleeves *12 is suitably shaped tofit approximately the ends of the rolls so that the ends of .the rolls may turn freely in them and the spaces between the opposing surfaces of two adjacent castings is such as to alloy the rolls no substantially end play without preventing their free rotation in their bushing.
2. In a machine of the kind described,
having top rolls and bottom rolls, and'castings spaced apart to formanopening to receive said rolls, a top roll having bushings freely supported thereonat each end, the opposing surfaces forming the ends of said opening being adapted to engage the ends of said bushings and prevent the endwise motion of said top roll.
3. Ina machine of the kind described comprising a frame and top rolls and bottom rolls, said top rolls having bushings freely supported on their ends, said frame comprising means to support said bottom 'rolls and Walls opposite to eachv other and having extensions at right angles to said walls, the Whole forming recesses to receive the bushings of said top rolls, said extensionsbeing spaced from the adjacent bottom roll a distance less than the diameterof said top roll, whereby said top roll it loose cannot pass by said bottom roll. a p
