ROLLER MILL ADJUSTING DEvIcE Filed July 14, 1932 INVENTOR dmm/ug NEY Patented Jan. 9, 1934 UNITED STATES 1,943,142 Y ROLLER 1mm. ADJUs'rnvG DEVICE Elmer P. Peters, Richmond Hill, N. Y., assignor to Kent Machine Works, Inc., a corporation of New York Application July 14, .1932.` Serial No. 622,384
3 Claimn. (Cl. 308-69) This invention relates to improvements in adjusting mechanisms to be used especially on roller paint mills and like machinery for acusting the several rolls in proper cooperative relationship.
5 The object of the invention is to provide. novel adjusting means whereby the adjustment of the rolls may be done quickly, accurately and with a minimum-of change and manipulation of machinery and operating parts and whereby two 19 adjacent adjusted rolls may in turn be adjusted as a single unit.
The invention will be more fully understood from the following speciflcation read together with theaccompanying ,drawing in which Figure 1 is an outline end view of a five roller paint mill equipped with adjusting devices embodying the invention, parts being in section and parts broken away.
Figure 2 is a partial side view of the mill looking in direction of arrow 2 in Figure 1.
Figure 3 is a detail sectional view of parts of the adjusting devices.
As will be understood from the drawing the roller mill comprises a main hollow housing within which is mounted a plurality of grinding rolls over which the material flows downward over the rollers and through the machine. In the passage through the machine the material-such as paint for instance is ground to the desired degree of iineness. Hence it is necessary that suitable adjusting means be provided for adjusting the rolls. It will further be understood that it is desirable to be able to adjust two adjacent rolls as a unit with relation to a third roll so as to maintain a prior adjustment between the two rst rolls.
The general construction and operation of this type of machines being well known in the art, only so much of the machine is illustrated as is necessary to understand the invention. v
One end of the framework or housing is shown in Figure 1 and is designated 5. In the housing there is mounted a ilxed roll 6 and two pairs of movable rolls 7 and 8, and 9 and 10. The four last named rolls are provided with shafts 11, 11
mounted in suitable bearing boxes 12, 13, 14 and 15. Cushion adjusting springs such as 16. 16
and 17, 17 are interposed between adjacent rolls and between the rolls and the housing as shown.
Novel adjusting means are provided for adjusting the rolls 8 and 9 with relation to the xed roll 6, and for adjusting the rolls 7 and 10` with reference to the rolls 8 and 9. The adjusting means include as a novel feature the movement or adjustment of the pair of rolls 7-8 and 9-10 respectively with reference to the fixed roll 6. The
adjusting means for the rolls 7-8 is identical with the adjusting means for the rolls 9-10 so the description of one will suice for the other.
The novel adjusting means are as follows. The frame or housing 5 is provided with a relatively long or deep cut out or bearing box slideway 18 in which the bearing boxes 12 and 13 are adapted' to slide vertically. The slideway 18 is closed by an end piece or head 19 but before being closed there is inserted in the slideway an adjusting U- piece formed with a transverse bridge 20 which extends through the slideway 18 at the open end thereof, and from the bridge 20 extends four legs.
'Two legs 21, 21 lie on the outside of the frame 5 and the two other legs 22, 22 lie on the inside of the frame 5 as best seen in Figures 2 and 3. The four legs are bolted to the innermost bearing box 13 by bolts 23.
The head 19 which closes the slideway 18 has an aperture 24. through which extends a shaft 25 which is in threaded engagement with the bridge 20 of the U-piece. The lower end of the shaft abuts the bearing box 12 and the upper end of the shaft carries a gear 26. Through the head 19 extends another shaft 27 in threaded engagement with said head. The end of the shaft 27 abuts\the bridge 2o. The shaft 27 has an operating handwheel 28 and it also supports another handwheel 29 to which is secured a gear v30 in mesh with the gear 26. The spaces 31 and 32 between the legs of the U-piece provides necessary freedom for the, up and down movement of the shaft 11.
From the foregoing it will be clearv that the rolls 7 and 10 may be adjusted with reference to the rolls 8 and 9 by moving their ybearing boxes 12 and 15 inwardly through operation of the handwheels 29, gears 30 and 26 and the shafts 25 abutting said bearing boxes 12 and 15, and moving them against the tension of the'springs 16.
Secondly, the rolls 8 and 9 may be adjusted with reference to the roll 6 by operation of the handwheels 28 and shafts 27 whereby the U- frames are moved inwardly sliding in the slideways 18 and against the tension of the springs 17. It will be noted as one of the features of the invention that when the rolls 8 and 9 are thus being adjusted towards the roll 6, the adjustments between the respective pairs of rolls 7-8 and 9-10 is not disturbed. It being also noted that when the U-frames are moved the gears 26 on the shafts 25 slide with reference to the gears 30.
It also follows thatA the U-frames may be backed away from the rolls 6 if desired, also without disturbing the relation between rolls 7 8 and 8-10. The construction herein disclosed therefore 'eliminates the necessity of re-adjusting the outermost rolls such as the rolls 'l and 10, when the adjustments of the inner rolls 8 and 9 is being regulated.
I claim:
1. In a roller mill, a main frame, a fixed grinding roll mounted therein, an auxiliary frame movably mounted with respect to the main frame, bearing boxes. supported in said auxiliary frame, movable grinding rolls journaled in said bearing boxes, a shaft for adjusting one of said bearing boxes within the auxiliary frame, a second shaft for adjusting the auxiliary frame with relation to the main frame whereby to adjust the said' movable grinding rolls with respect to the said fixed grinding roll.
2. In a roller mill, a main frame, a xed grinding roll mounted therein, an auxiliary frame movably mounted with respect to the main frame, bearing boxes supported in said auxiliary frame, movable grinding rolls journaled in said bearing boxes, a shaft in operative engagemeni with said auxiliary frame for adjusting one of said bearing boxes within the same, a second shaft in operative engagement with the main frame and abutting the auxiliary frame for adjusting the latter with respect to the main frame whereby to adjust the said movable grinding rolls with respect to the said fixed grinding roll.
3. In a roller mill, a main frame, a fixed grinding roll mounted therein, an auxiliary frame movably mountedwith respect to the main frame, bearing boxes supported in said auxiliary frame, movable grinding rolls journaled in said bearing boxes, a shaft in threaded engagement with the auxiliary frame and adapted to adjust one of the bearing boxes with respect thereto, a gear on said shaft, a handwheel and second gear for operating said shaft gear, a second shaft extending through said handwheel and iii-st gear and in threaded engagement Y with the main frame for adjusting the auxiliary frame with respect thereto whereby to adjust the said movable* grinding rolls with respect to thesaid fixed grind- *ng roll.
