Claims.
This invention relates to improvements in paper making machinery and is directed more particularly to apparatus for rotatably support ing and manipulating the breast roll of a paper making machine.
The principal objects of the invention are directed to the provision of apparatus for rotatably supporting a breast roll and for moving the same from operating position.
In a Fourdrinier paper making machine it is necessary to frequently replace the Fourdrinier wire and to facilitate this, it is desirable to remove the breast roll over which the wire runs.
The apparatus of this invention is constructed and arranged to rotatably support the breast roll in operative position and to move the same away therefrom for removal of the Fourdrinier wire.
With the foregoing and various other novel features and advantages and other objects of my invention as will become more apparent as the description proceeds, the invention consists in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more particularly pointed out in the claims hereunto annexed and more fully described and referred to in connection with the accompanying drawings wherein:
Fig. l is a side elevational view of the apparatus embodying the novel features of the invention;
Fig. 2 is a transverse sectional elevational view through one of the breast roll stands of the ap-. paratus; v
Fig. 3 is a combined plan and sectional view at an end of the breast roll showing the constructionof the breast roll bearing;
Fig. 4 is a plan view of one of the bushings for the breast roll bearing;
Fig. 5 is a front elevational view of the appara tus shown in Fig. 1; a
Fig. 6 is an elevational view of the upper end of one of the lift levers; and
Fig. 7 is a plan view of the bolt for holding the bearing stand cap in operative position. Referring now to the drawings more indetail, the invention will be fully described. 1
A pair of support members 2 are provided which may be supported by the floor, structural work or the like at either side of a paper making machine and to which parts of a paper makingmachin maybe secured if desired. a Shafts 4 are journalled inlower portions of the support'members and have flanges 6 secured e eto, a shown g 'An int rmediate 2 shaft 8 between said shafts 4 has flanges III which are secured to flanges 6 by any suitable means such as bolts, not shown.
Lift levers l2 have lower ends fixed as by keys I4 to the shafts 4 and are movable between the upper operating position of the breast roll as shown and a lower position accordingly as the shafts 4 are oscillated in one direction or the other.
The shaft may be oscillated by any suitable means but'for purposes of disclosure a cylinder [6 is provided which is secured to a spacer l8 that is secured to one of the members 2. A piston 20 is reciprocable in the cylinder, see Fig. 1.
A piston rod 22 extends forwardly from the piston and it has a cable 24 connected by 26 to the forward end thereof. A forward end of said cable 24 is fixed to a segment 28 which is fixed to shaft 4.
Fluid may be supplied cylinder l6 by means of a pipe 30 andas fluid is delivered to said cylinder may be vibrated. v
the piston is moved to the right whereby through the piston rod and cable the members 12 are moved clockwise from a lower to operating position shown in Fig. 1. Pressure may be retained in the cylinder by means of a valve in line 30 and when pressure is released by said valve the piston may move forwardly and the members 12 may swing downwardly from the position of Fig. 1.
Locking members 32 rod-like in form are provided which are insertable through members [2 into suitable openings of hubs 34 of the supports, see Fig. 5. These hold the members l2 in the operative position shown.
The upper end of members l2 are provided with bores such as 36 having throat openings 38 leading thereinto transversely to the longitudinal axis, see Fig. 6. p
A bushing such as 40 is provided, one for each member 12 which has a central bore 42, see Fig. 4. These are insertable longitudinally in the bores 36 ofmembers l2 and fit therein as will appear. Manually engageable members 44 are provided on the'bushings 40 to facilitate insertion in and withdrawal from the bores 36. Plate members 46 have lower ends secured to opposite sides of. the support members 2 by means of plates 48 and screws or bolts 50.
Roll stands 52 are provided which have lower ends secured to upper ends of plates 46 by means of (plates 54 and bolts 56.
The members 46 are arranged and constructed to permit slight movements or vibrations of the stands back and forth whereby the breast roll The members 52 are provided with semi-circular seats 60 as shown in Fig. 2. Caps 62 are provided which are pivoted at 64 in the members 52 and have semi-circular seats 66.
V Bolts 68, see Fig. '7, are provided which have openings in inner ends thereof and extend through openings 10 in members 52, see Fig. 2. The caps 52 are provided with lugs 14 which are receivable in the openings 10 of the bolts 68. Washers l6 bear on members 52 and nuts 18 on the bolts may be manipulated to draw the caps 62 inwardly.
Bearing housings, such as 80, are provided on the opposite ends of a breast roll 82., see Fig. 3.
Each housing 80 is mounted for rotation on a reduced portion 84 of shaft 86 at the end of the breast roll by means of an anti-friction bearing 88. A cap 90 is secured by any suitable means to the housing 80 and a plate 92 is secured to the end of shaft portion 84 to prevent endwise movement of the housing on the shaft.
A hollow pilot portion 94 extends outwardly from the housing 80 and has a bore 95 for lubri eating the bearing 88 which said bore is closed by a plug 98.
The bearing housings on the breast roll shafts are disposed in the roll stands 52 by being clamped in the seats 60 thereof by the caps 62 which are swingable in the roll stands.
The breast roll is freely rotatable and the stands may be vibrated back and forth so that the breast roll moves axially back and forth.
When it is desired to lower the breast roll the bushings 40 are slipped over the pilot portions 94 of the breast roll shaft housings and into the bores 36 of members l2. 7
Normally the pilot portions 94 are free of the bores 36 so that the breast roll may be vibrated.
With the bushings inserted as described the breast roll may then be supported by members I 2 and the caps 62 of the roll stands may be swung downwardly to release the breast roll from the stands 52.
With the breast roll supported by members I2 and with locking members 32 withdrawn to release members I2, pressure in the cylinder I6 is released slowly so that the breast roll and member l2 may swing downwardly counterclockwise.
There may be a truck or other device to receive the breast roll and move it axially from the paper machine. The breast roll is released from the members I2 by withdrawing the bushing 40.
When the breast roll is to be lifted into place and the pilot portions 94 are in the bores 36 of the members l2, the bushings 40 are slipped into place on the pilot portions and said members I? are swung upwardly clockwise by movement of the piston 20. When the bearing housings 80 7 are in the roll stands the caps 62 are secured in place for holding the said housings in the stands 52. r
The invention may be embodied in other specific forms without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all modifications and variations as fall within the meaning and purview and range of equivalency of the appended claims are'therefore intended to b6 embraced therein.
