Patented Apr. 7, 1942 PRINTING CYLINDER Joh-n P. E. Neilson, Quincy, Mass., assgnor to Meisel Press Manufacturing Company, Boston, Mass., a corporation of Massachusetts Application December 13, 1940, Serial No. 369,969
9 Claims.
This invention relates to cylinders and the ob'- ject is to provide an improved construction facilitating the tight application of a flexible member tothe surface of the cylinder and ensuring its secure retention thereon.
My invention will be well understood by reference to the following description taken in connection With the accompanying drawings, where- Figs. 1, 2 and 3 are partial transverse sections through the cylinder illustrating successive steps in securing ends of flexible members thereto; and
Fig. 4 is a broken section on the line 4-4 of Fig. 1, the flexible member being omitted.
Referring to the drawings, I there show a printing cylinder 6 organized between the usual terminal bearers 8 (Fig. 4). The body of the cylinder between the bearers is provided with a gap opening to the surface of the cylinder through a narrow longitudinal slot I and within which, inwardly of said slot, lies a reel rod I2 more fully hereinafter described. About the surface of the cylinder is wrapped a exible member I6, such, for example, as a rubber blanket or a rubber printing plate and eitherA the two ends of a single encircling member or the opposed ends of separate members, the opposite ends of which are secured to the cylinder in the same or some other manner elsewhere in the circumference, are adapted to enter the slot I0 and be secured by the reel rod I2 within the gap. For convenience I will refer in the following description to the exible member as a blanket and in the claims to avoid awkwardness of expression will refer to the ends which are engaged as the ends of a flexible member.
The preferred mechanical construction herein illustrated as forming the slot IIJ and providing for the mounting of the reel rod I2 comprises a generally rectangular recess I8 formed in the body 6 of the cylinder, the bottom of the recess being provided with a groove 20 semi-circular in cross-section and tangent to the right-hand side of the recess viewing Figs. 1, 2 and 3. A filler block 22 is secured in the recess at the lefthand side thereof, this block having an outer surface continuing the contour of the cylinder and an overhanging portion provided with a segmental groove 24 which, when the parts are assembled, matches the groove 20. The member terminates a short distance from the right-hand wall of the recess, thus defining the narrow slot Ill which opens tangentially to a cylindrical seat formed by the cooperation of the two grooves and adapted to receive the reel rod I2 which is genlill-415.1)
erally of the form of a cylinder corresponding in diameter to the seat referred to.
The single reel rod I2 herein is adapted to engage successively the ends of the blanket I6 to draw these ends down into the gap to secure the blanket in tight encircling relation to the cylinder and to clamp these ends against the wall of the gap in direct engagement one with the other. Referring to Fig. 1, the rod I2 may be cut away to provide a seat 26 for the right-hand end of the blanket I6. This seat preferably takes the form shown of a half a circular segment defining an abrupt shoulder 28 and an unobstructed portion above the same so that, with the rod in the position .of rotative adjustment shown in Fig. 1, the right-hand end of the blanket 26 may be thrust in through the slot III by a mere movement of approach substantially radial to the cylinder as a whole until the edge of the end engages the shoulder 28. To the rear of the seat 26, considering the forward rotation of the reel rod to clamping position, or counterclockwise viewing the figures, there is provided a clamping shoulder 30 which as a matter of mechanical construction is formed by a slight reduction or cutting away of the cylindrical rod at this point in an amount somewhat smaller than the normal thickness of the blanket I6. To permit this portion 3U not only to press against the end of the blanket but to grip the same to effect downward traction thereon, it is preferably toothed, herein with long rib-like teeth extending along the length of the cylinder.
One end of the blanket being engaged in the seat 26, as shown in Fig. l, the reel rod I2 is rotated clockwise and the toothed portion 30 engages the end of the blanket and, the teeth gripping the same, the end is carried down to the position shown in Fig. 2, tensioning the blanket over the right-hand margin of the slot I0 at the cylinder surface and pressing the end against the opposed wall of the gap as dened by the groove 20. To the rear of the vportion 30 there is provided a seat 32 similar to the seat 26 whichA is then brought into position beneath the slot I6, as illustrated in Fig. 2. To the rear ofthe seat 32 the rod is again cut away to provide a toothed clamping portion 34 similar to the portion 3D but preferably of somewhat lesser radial depth measured from the center of the rod and of substantially greater circumferential extent for reasons'which will appear. The right-hand end of the blanket is inserted through the slotv I0 and placed in the seat 32, as shown in Fig. v2,. `Continued clockwise motion of the reelrod will,l
then bring the parts to substantially the position of Fig. 3 in which it will be seen that the movement of the left-hand end of the blanket under the gripping action of the portion 30 has continued while the portion 34 grips the right-hand end of the blanket, draws it down through slot I 0, presses it directly against the right-hand end and clamps both of them rrnly against the wall of groove 20. The relatively reduced height of shoulder 34 accommodates the double thickness and its circumferential length provides for a wide range of rotative adjustment. Thus a further movement beyond the position of Fig. 3 and continued take-up of the blanket is clearly possible. Reverse rotation of the reel rod, that is, in a counterclockwise direction, viewing Fig. 3, will free the ends of the blanket, and it is to be noted that, since the ends of the blanket engage the abrupt shoulder 28 of seat 26 and the corresponding shoulder of seat 32, these shoulders will feed backwardly the end portions of the blanket and positively eject them free of the reel rod.
In the mechanical construction shown in the drawing the reel rod has a considerable cylindrical surface which finds a bearing throughout its length on the seat provided by the grooves and 24. In Fig. 4 I have shown the left-hand end of the rod extending through the left-hand bearer 8 and as provided with an integral flange 36 to overlie the face of that bearer and a squared portion 38 by which it maybe turned. The flange 36 is herein shown as a ratchet wheel to engage a retaining pawl, not shown, for holding the rod in position after theblanke; has been tightened up. 'I'he Aother end ofthe rod may be provided with a reduced end 40 on which Arits a sleeve 42 providing a bearing in the right-hand bearer 8 and having the flange 44 overlying the outer face of the same, this sleeve being secured in position by the key screw 46. Obviously the reel rod may be assembled in its seat by being introduced thereinto from the left-hand side, viewing Fig. 4, and secured by the applicationof the sleeve 42, either before or after the block'22 is secured in place.
I am aware that the invention may be embodied in other specific forms Without departing from the spirit or essential attributes thereof, and I therefore desire the present embodimentl to be considered in all respects as illustrativetand not restrictive; referencev being had to the appended claims rather than to the foregoing description to indicate the scope of the invention.
