ROLL-SUPPORT.

Specification of Letters Eatent. Pafigmt'ggd MI 24 1921] Application filed October 27, 1919. Serial No. 333,818.

To all whom it may concern:

Be it known that I, LORENZ FLIoK, a citizen of the United States, residing at Saylesville, in the county of Providence, State of Rhode Island, have invented a certain new and useful Improvement in'Roll-Supports, of which the following is a specification, reference being had therein to the accompanying drawings.

The features of the invention are applicable in a variety of connections in which rolls require to be mounted removably in working position. An important line of employment of the said features is in connection with rolls and the like on which a continuous web of sheet material is wound. l/Vhen employed in such connection they facilitate the mounting of an emptyroll or the like in position to be driven and to re ceive a load of the continuous sheet material, and they provide for ready and convenient removal of the wound roll. They are especially applicable in connection with the receiving rolls of textile machinery, but are not confined to use in this connection, since they may be used for supporting and facilitating the removal of the rolls of paper-making machines, printing presses, etc.

Some of the features of the invention are generically new, so far as I am aware, and the principles thereof admit of being embodied in various specific types of construction, with more or less variation in the form, etc., of the mechanism. A. more specific phase of the invention provides a special organization of novel and improved cha acter. The drawings show the said organization with the various features of the invention embodied therein.

In the drawings, Figure 1 is a view partly in side elevation and partly diagrammatic 'showingthe said organization in conjunction' with certain of the elements of a mangle 0r cloth-oalendering machine, the roll-support being in its closed or roll-supporting position.

Fig. 2 is a similar view showing the parts in the positions assumed by them upon the discharge ofa roll.

Fig. 3 is a side elevation, Fig. 4: a back elevation, and Fig. 5 an end view, of the end portion or bracket of a carrier arm.

Fig. 6 is a side elevation, and Fig. 7 is a plan of the bearing-member which is moun ed upon the said end-portion or bracket.

Fig. 8 is a side elevation, and Fig. 9 a plan, of the operating lever which is combined with the said bearing-member.

Fig. 10 is a side elevation, and Fig. 11 an edge view, of one of the links connecting the said lever with the said bearingmember.

The drawings show the features of the invention embodied in an organized rollsupport which is employed in connection with the roll, 1, on which a web of cloth, 2, is wound as the said web leaves the top roll, 3, of the stack of rolls, 3, a, 5, of a mangle or cloth-calendering machine. The said roll-support is movable toward and from the roll 3, and the receiving and winding roll 1 applied to the roll-support is driven through frictional engagement between the periphery of the roll 3 and the exterior of the cloth alreadyupon the roll 1. The said engagement is provided for by arranging the roll-support so that the driven roll gravitates toward the driving roll 3, thereby insuring peripheral contact between the two rolls. The movability of the roll-support enables it to recede from roll 3 as the diameter of the cloth wound thereon increases.

As the roll which is to be supported requires to be sustained at both ends thereof, and as the supports for both ends are essentially similar, it will be understood that the following description'of the organization at one end of the said roll applies equally in the case of both ends.

The illustrated roll-support comprises, essentially, a carrier 6 which gravitates toward roll 3, a bearing-member 1O movably connected with said carrier and adapted to receive a journal of roll 1, or of the spit or arbor which is employed in connection with said roll, and means for controlling the said bearing-member whereby it may be operated to dispose it conveniently for the application of the said journal in mounting the roll in connection with the roll-support, and then dispose it in proper relation to retain the journal during the performance of the operation or process in which the roll participates (herein the winding of the cloth upon the roll 1), and later on dispose it so as to provide for the release of the roll.

given its roll-supporting position.

The gravitating carrier is in this instance an arm 6, arranged to swing around an overhead pivotal axis toward and from the periphery of the driving-roll 3, the two arms at the: opposite ends of the roll 3 being pendent from a rockshaft 7 mounted in elevated bearings (not shown). The tendency of the roll-support and the roll 1 to gravitate toward the driving-roll 3 is increased by means of a pressure-weight 8, mounted upon an outstanding branch 6 of the arm 6, and adjustable upon the said branch to vary its effect in holding the roll 1, or the exterior of the cloth which has already been wound thereon, against the periphery of the roll 3. At 9 is a clamping screw, by means of which the weight 8 is held in adjusted position upon the branch 6"-.

The bearing member 10 is in this instance movably combined and connected with the carrier for the purposes of the inventionby being hung pivotally at 10 (Figs. 2, 3, 4 and 6) to the bracket 6*, shown separately in Figs. 3, 4 and 5, constituting the lower end of the arm 6. The said bearing-member 10 is formed with an open bearing 10*, said open bearing being shown as occupied by a half-box or bushing 10 to receive the journal 1 of the roll 1. The pivotal hanging of the bearing-member 10 upon the carrier permits it to assume either a depressed and rearwardly retracted receiving and discharging position like that shown in Fig. 2, which releases a journal occupying the bearing and permits transverse discharge thercof or the introduction of a roll-journal, or the forwardly-advanced and upturned rctaining position shown in Fig. 1, in which the said open bearing faces upwardly and is adapted to hold the roll-journal, and so that the latter may revolve therein.

The means for controlling the said bearing-member 10 comprises in this instance an operating lever 11, pivoted to bracket 6 at 11 and having link-connection with the bearing-member. The operating lever 11 is shown separately in Figs. 8 and 9.

The two side-portions of the lever-hub are separated sutficiently to receive the bracket-portion of the carrier-arm 6 be tween them, the lever being pivoted to the said bracket by means of the pivot-pin 11 occupying a transverse hole 6 in the bracket, the ends of said pin fitting holes 11*, 11*, in the side-portions of the lever-hub. The cross-bar 11 connects together the two sideportions. In one position of the operating lever the said cross-bar makes contact with the back of the bracket 6 and thereby limits the play of the lever in the direction of movement by which the bearing-member is The links 12 (one thereof being shown separately in Figs. 10 and 11) are employed between the lever and bearing-member, one at each sideof the latter two, the upper ends of the said links being engaged with opposite crank- pins 13, 13, Figs. 8 and, 9, projecting transversely from the sides of the lever-hub, and their lower endsbeing" engaged with crank-pins 14:, 14:, constituted by the opposite ends of a pin extending through a transverse hole 15, Fig. 6, in the bearing-member, located eccentrically with relation to the pivot 10 of the said bearingmember. Y

When the operating lever 11 is swung about the axis of its pivotal'connection with the carrier arm, forward and downward from the position occupied by the lever in Fig. 2, the crank and link connection be tween-the said lever and the bearing-member causes the bearing-member to be swung forward and upward about. the axis of its pivotal connection with said carrier arm, from the retracted open position shown in Fig. 2 to the upturned position occupied'in Fig. 1. The construction is such that in the extreme position of the lever which is shown in-Fig. 1, namely with the crossbar 11 resting against the back of the bracket per-- tion of the carrier-arm, and with the bearing-member in its closed or roll-supporting position, the crank- pins 13, 13, are located slightly beyond centers; that is to say, are located slightly beyond a straight line intersecting the axis of the lever-pivot 11 and that of the crank-pins 14:, 14:. Consequently, the links and the cranks of the lever form a toggle-lock which locks the bearing-member against movement due to the load supported bythe bearing-member and, tending to cause it to swing around its pivot. The lever 11 retains this positionthrough the action of gravity upon its main outwardly extending arm, to which a small weight 11 is shown applied to increase the effect. When the operating lever is swung reversely, it acts through its connections with the bearing- -member to swing the latter toward its releasing position shown in Fig. 2. The

weight of a roll supported by the bearing member will assistin this action.

At 16 is shown a table which is placed below the roll 1 in position to receive the latter as its journal discharges or is removed from the bearing-member.

The release of the roll-journal from the roll-support frees the latter which there? upon gravitates rearward from the journal toward the roll 3,'as in Fig. 2. .As the'rollsupport assumes the position shown in Fig. 2, in which the pivot of lever llis carried forward relative to the weighted arm of such-lever, the latter gravitates downward toward and into its position occupied in Fig. 1, thereby automatically turning the bear ing-member into position to support a rollournal. V

The extent of the opening movement of the bearing-member may be limited, if desired, by constructing the parts so that in the said opening movement the back of the cross-bar 11 of the operating lever shall make contact with the back of the bracket 6", as in Fig. 2.

For the convenience of the operator in moving the operating lever 11 to give the bearing-member its open or discharging position, a cord or chain, 17, is shown, connected at one end with the said lever, and extending therefrom around guide sheaves, 17 17 with its opposite end hanging down at the front of the receiving roll, and furnished with a handle, 17 to be grasped by the operator.

For the purpose of locking the roll-journal in the bearing of the bearing-member so as to prevent the roll-journal from jumping out of the said bearing, I provide one or each of the links 12 with a spur 12 which projects forwardly there- 'from. In the closed position of the bear ing-member that is illustrated in Fig. 1, this spur extends over the open bearing, above the roll-journal, so as to prevent the latter from jumping. When the bearingmember is moved into its open or discharging position, the open top of the bearing is moved downward away from this spur, and thereby the bearing is uncovered so as to re lease the journal of the roll.

While I have illustrated and described one form in which the invention may be embodied, I am aware that many modifications may be made therein by any person skilled in the art, without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited to the particular form shown, or to the details or" construction thereof, except in the case of the more specific claims below, but

What I do claim is 1. The combination, in a roll-support, with a gravitating" swinging arm, of a j ournal-engaging member connected movably with said arm, a gravitating operating lever, a link-connection between said lever and the said journal-engaging member and through which said lever moves said member into working position for engagement with a roll-journal and withdraws such member to free the rolljournal, and stops defining a position of said operating lever and link-connection in which they form a toggle-lock for the journal-engaging member.

2. The combination, in a roll-support, with a gravitating swinging arm, of a j ourlnal-engaging member connected movably with said arm, a gravitating operating lever pivoted to said arm, a link-connection between said lever and the said journal-engaging member and through whichsaid lever moves said member into working position for engagement with a roll-journal and withdraws such member to tree the rolljournal, and stops defining a position of ,said operating lever andg link-connection in which they form a toggle-lock for the j ournal-engaging member.
