2 Claims. (Cl. 19-108) atent For cleaning top fillets, it has been a common practice to use cylindrical revolving brushes having swine bristles and stripping rollers having wire bristles. The stripping rollers are usually called stripping fillets and are used intermittently or periodically, because their continuous use is not necessary, but would result in undue and useless wear of sharp edges and disturbance of uniformity of top fillets.

The main object of the present invention is to provid a stripping roll or a combined rolling brush and stripping fillet in which the effectiveness of the stripping fillet may be readily and precisely adjusted at will.

Another object of the present invention is to provide means for conveniently adjusting the operative position of stripping fillet.

A further object of the invention is to provide a stripping roll of the kind specified which may be operated from either end in an identical manner.

Other objects and advantages of the present invention will be obvious from the rfollowing detailed descriptions with reference to the accompanying drawings showing a preferred embodiment of the invention, in which:

Fig. 1 shows a longitudinal sectional elevation of the stripping roll;

Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1, partly broken away;

Fig. 3 is a cross-sectional View taken `along line III-III `in Fig. 1; Fig. 4 is a cross-sectional View taking along line IV-IV in Fig. 1;

Fig. 5 is an enlarged sectional view of the left end portion of Fig. l; and

Fig. 6 is an end view of the locking cup.

Referring to the drawings, theA stripping roll according to the invention comprises a pair of tubular horizontal shafts 1 and 2 which are arranged in axial alignment and are respectively provided with end plates 3 and 4 ixedly mounted thereon near their outer ends. Within the tubular shafts 1 and 2 and extending longitudinally therethrough, a pair of bar shaft 5 and 6 are rotatably mounted by means of suitable bearings 7 provided at the opposite ends of the shafts 1 and 2, respectively. The bearings 7 are fixed to the corresponding ends of the shafts 1 and 2.

The shaft 5 is provided with screw threads 8 on a portion of its length, and-a nut member 9 is mounted thereon and engages the screw threads. A Iradially projecting pin l@ is fixed to the nut member 9 `and extends through an elongated slot 11 longitudinally formed in the Wall of shaft 1. A 'slide 12 is mounted on the tubular shaft 1 for slidably moving therealong, and the outer end of pin 10 engages the slide 12 in a hole or recess Patented Apr. 26, 1960 Y if? mechanical connection between the

members

8 and 12. Y

The slide 12 is provided with a spaced pair of oppositely disposed

lugs

13, 13, and a pivot pin 14 extends therebetween and is supported therein, with its opposite ends projecting outwards beyond the

lugs

13, 13. The pin 14 carries at its projecting ends an inverted U-shaped operating yoke member 15 for pivotal movement. The yoke member 15 straddles over the shaft 1 with its leg ends pivotally mounted on the pin 14, and is provided at its top or bite portion 16 with an outwardly projecting arm 17 which is pivotally connected to an adjustable stripping fillet consisting of outwardly directed wire bristles 18 planted on a base plate 19. The base plate 19 is formed with a suitable recess 20 into which the arm 17 extends, and the arm is pivotally connected to the plate 19 by pin 21.

The opposite ends of the base plate 19 are slidably fitted in radially extending slots 22 and 23 formed in end plates 3 and 4, respectively, and the stripping fillet 18-19 is radially movable or adjustable under control of the yoke member 15, as hereinafter to be described. 1n the drawings, the slots 22 and 23 are respectively formed in additional thick plates secured to respective end plates 3 and 4.

Additional slides 12a and 12b similar to slide 12 are slidably mounted on the tubular shafts 1 and 2, respectively. The additional slides 12a and 12b are provided with spaced pairs of oppositely disposed lugs 13a and 13b, respectively, in which pivot pins 14a and 1412 are journalled respectively for pivotally carrying inverted U- shaped yoke members 15a and 15b in a manner similar to the operating yoke member 15. Additional yoke members 15a and 15b are also pivotally connected to the base plate 19 of the stripping iillet, and are arranged in parallel with the yoke member 1S. All the

pins

14, 14a and Mb are pivotally connected with a link 24. Thus, the yoke members constitute a parallelogram with base plate 19 and link 24.

The bar shaft S is provided at its inner end with a gear wheel 25 fixed thereto, while the bar shaft. 6 carries at its inner end a gear wheel 26 fixed thereto. The gear wheel 2S meshes with a gear wheel 27 which is fixed to a co-axial gear wheel 2S. The

gears

27 and 28 are rotatably mounted on a pivot shaft 29 within a gear box 30. The gear 28meshes with a pinion 31 which in turn meshes with the gear 26. The pinion 31 is mounted on a pivot shaft 32 in the gear box 30.

The gear box 30 is secured to the adjacent inner ends of the tubular shafts 1 and 2 depending therefrom, and the link 24 is so shaped that it is cleared oi the gear box 30 at its corresponding portion as will readily be lseen from Fig. 2.

With the arrangement described above, when one of the bar shafts 5 and 6 is rotated in one direction, the other bar shaftl is rotated in the opposite direction as shown by the arrows in Fig. 1. Each of the bar shafts 5 and 6 are provided at their outer ends with

polygonal heads

33 and 34, respectively, through which the respective shafts 35 forming a generally cylindrical body, on which swinel bristles 36 are provided in spiral forms and constitute a rolling brush. The plates 35 are secured at their oppositev ends to the respective end plates 3 and 4. One

3 of the plates 35 is subdivided into two circumferentially spaced parts 35a and 35h, between which a radially open through channel 37 is formed. The stripping fillet 18-19 can pass through the channel 37 in its radial adjusting movement.

In normal operation of the stripping roll, the stripping llet 18-19 is to be held in its retracted position in which the wire bristles 18 are held inner' than the rolling brush 36. ln the drawings, the stripping fillet lS--19 is shown in one of radial positions in which the sharp points of wire bristles 1S are substantially in the same cylindrical plane as the outer ends of swine bristles 36.

When either of the

operating heads

33 and 34 is rotated in a proper direction, for example clockwise, the bar shafts and 6 are rotated in a same sense as hereinabove described, and the nut member 9, being held against rotation, is caused to travel longitudinally in the corresponding direction shown by the arrow. ri'he slide i2 moves along with the nut member 9, simultaneously driving all other slides 12a and 12b through the link 24 to slide along the tubular shafts 1 and 2, respectively. This causes simultaneous tilting movement of yoke members 15', 15a and 15b. inasmuch as the base plate i9 of stripping llet is prevented from moving in the longitudinal direction by abutment with end cover plates 3 and 4 of the roll, the base plate 19 is forced radially outwards through the channel 37, causing the wire bristles 18 to project beyond the swine bristles 36 into an operative position. When the

operating head

33 or 34 is rotated counterclockwise, nut member 9 and slide 12 are caused to move in the reverse direction, so that the stripping llet 18-19 is retracted radially inwards into its inoperative position. When in the operative position, the stripping llet 18-19 functions to rake out wastes from the deepest portions of the top iillet, not shown, while the swine bristles 36 remove the waste out of the top fillet. It will be obvious that the effectiveness of wire bristles 18 may readily and precisely be adjusted by appropriate operation of the shaft 5 or 6, and the stripping fillet is maintained in its adjusted position by virtue of the nut member 9 engaging the screw threads 8 of the bar shaft S which is held against rotation by frictional resistance. If necessary or desired, however, a suitable additional means may be provided for locking the shaft 5 or 6 against rotation.

In Figs. l, 5 and 6, a positive locking device is shown i' provided on the outer end of the shafts 1 and 5. Adjacent the outer end, the tubular shaft 1 and the bearing member 7 are formed with a radial recess 40, in which is retained a steel ball 41 under outward biasing force by a compression spring 42, with a portion of the ball 41 yieldably projecting beyond the peripheral surface.

A locking cup 43 is provided having a central opening 44 of polygonal contour in the bottom and a number of holes 45 circumferentially arranged around the peripheral wall 46. The polygonal opening 44 is adapted to snugly t on the correspondingy polygonal operating head 33, thereby holding the shaft 5 non-rotatable with respect to the locking cup 43, while the cup 43 is prevented from rotation with respect to the tubular shaft 1 by virtue of the engagement of one of the holes 45 on the ball 41. When the adjustment is to be effected, the locking cup 43 is removed. After the adjustment has been effected, the cup 43 is applied on to the shaft ends, and one of the holes 45 engages the ball 41 to lock the shaft 5.

In order to obtain complete stripping of top llets, yit is important to properly adjust the operating position of the wire bristles 18 relative to the top fillet, and according to the present invention, this can be accomplished in a convenient and positive manner.
