ROLL JACK.
Application and Jui'y 21,
My invention relates to roll jacks and has particular reference to a jack used in connection with rolling mills for handling rolls and also driving spindles for the rolls.
Another and further object of my invenytion is a provision o f a roll jack which takes the place of a crane in the handling of driving .spindles and in which a material amount of time and labor is saved in changing the A1o rolls, or in changing the driving spindles of the rolls.
In connection with the changing of rolls from one stand to another, heretofore it has been the practice to employ cranes which frequently are in use at some other point in the mill and which must be run to the point where the spindles are located and a y great deal of time is consumed in removing the spindles by the use of the crane.
In my improved device the jacks are. preferably permanently positioned adjacent to spindles, so that in ease it is desired to change the rolls, the spindles are lifted and disconnected from the rolls vand f allowed to remain in position on the jacks if desired when new rolls are put in the stands. The jacks are also capable of manual manipulation thus materially lessen'ing the length of time required for connecting the driving spindles to the rolls, and may be used for the handling of the rolls as well as the driving spindles.
These and other objects of my invention` will be more fully and better understood by yreference to the accompanying sheets and drawings, and in which:
Figure 1 is an end view of a roll housing, with the jacks in position adjacent the hous- Figure 2 is a side view partially in elevation and partially in section, showing the roll jacks in position alongside the roll stand;
Figure 3 is a side elevational View ofthe roll jacks inoperation.
Figure 4 is an end view of the jacks, as shown in Figure 3.
Referring now vspecifically to the drawings a roll'housing l0 is shown, which is mounted upon the usual concrete foundation 11, 'with a lower roll 12` and upper roll 13 mountedtherein in the yusual manner. lThe upper driving spindle 14is shownhavingI a couplingbox 15 on Aone end thereof whichv is adapted to fit over the squared end16 of a driving spindle 11 and also over the-squared jection 18 on the driving spindle 14.
1327. Serial No. 207,487. y
1t will be understood that in the construction justvdescribed, the driving spindles 14 and 19 lead to another roll stand, which is 70 positioned in alinement with the roll stand 10, the roll from the stand 10 being driven from the rolls in adjacent stands, which is coimnon practice in rolling mills at the present time-in fact it is common practice to place several'roll stands in alinement and then drive the one set of rolls from the com mondriving shaft leading to a source of power located in a power house adjacentto the mill, and. then connect the rolls in the alined rolling stand, so that the rolls of these stands are all driven thru a common power shaft. In this arrangement it is frequently necessary to `change the rolls and in changing the rolls it is of course necessary to disconnect the driving shaftsand my invention is designed particularly for this purpose.
Positioned upon the foundation 11 is a pair of roll jacks designated as a whole as 22 and 23. These jacks comprise a base composed of a pair of angles 24 and 25, which are connected at each of their ends by transverse angle members 26`and 27, adapted to extend into recesses 28 and 29 formed in foundation 11. These members have a pair of standards 30 and 31 secured thereto by means of rivets 32-32 with a reenforeement member 33. Positioned between members 30 and 31, at the lower ends thereof, which-acts as a spacing member for said members 30 and 31, and is riveted thereto by means of rivets 34-34 and is also secured the angles 24 and 25 by rivets 35 35.
At'the upper end of the said members 30 and 31 a spacer 36 'is provided with a rivet -105 v37 passing thru the members 30 and 31, so that the members 30 and 31 are built up into vertically extending standards adapted to support the pivotally mounted levers Y adapted to lift and support the couplin'g. 110 box, as hereinafter described.
Extending between the standards 30 andY 31 and pivotallyl mounted thereon, is a lower lever 38, having a curved forward end- 39 adapted to rest under the driving spindle 19, the said lever 38 being pivotally mounted to the members 30 and 31 by a loose pin 40 extending thru these members and thru the lever 38. Y
A elevis 41 is provided which is pivotally Vsecured tothe rear end of the lever 38 and by a pin 42, the said clevis extending downwardly thereof to the front side of the members 30 and 31, as adapted to engage in a lurality of notches 43, 43 formed by the orward sides of these members. A handle 44 is provided having a socket 45 in one end thereof and is tapered olf to a wedge shaped end 46 at the outer end thereof, the handle 44 being adapted to fit overl the outer end of the pivotally mounted lever 38.
A plurality of holes 47, 47 are provided in the members 30 and 31 near the lower ends thereof, adapted to receive the pin 40, so that the lever 38 may be changed to different positions to4 correspond to different heights of the coupling box leading to the roll mill.
In the upper ends of the members 30 and 31 is mounted a second lever 48 upon a pin 49 extending thru the members 30 and 31 the said lever 48 havingea curved forward end 50 adapted to be positioned under the upper drivlngspindle 14. A clevis' 51 is rovided which is connected to the lever 48 y a pin 52 and which extends across to the forward side of the members 30 and 31 and is adapted to en age notches 535-53 formed on the edges of t ese members. The handle 44 is adapted to apply over the end of the lever 48 for the purpose of lifting the driving s indle 14 in the same manner as heretofore eseribed with relation to the lower lever 38.
clevises in the meantime engaging in the' notches so that the weight ot' the coupling boxes is sustained by the levers. The handle 44 is removed from the jacks and the tapered end is used to pry the coupling boxes over onto the driving spindles in the position shown by dotted lilies in Figure 2. The spindles are allowed to remain in position upon the jacks so long as may be needed during the changing of the rolls.
Though certain preferred embodiments of the present invention have been described in detail, many modifications will occur to those skilled in the art, it is intended to cover all such modifications that fall within the scope of the appended claim.
I claim:
A roll jack comprising in combination, a base member, means on said base member for `interengagement with the roll stand base, a
pair of spaced vertical members secured to said base member having notches on one of their edges, a pair of pivotal mounted members positioned between the said vertical members in spaced vertical relation with each other, and retaining members secured to said pivotal members at one of the ends and adapted tov be' received in the notches on the sides of said vertical members.
