JAMES B. REPLOGLE, 0F CHICAGO, ILLINOIS.
PRINTINGPRESS.
Application led J-,une 28, 1913.
T0 all whom it may concern:
Be it known that I, ,LAMES B. REPLoGLn, citizen of the United States, residing at Chr cago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Printing-Presses, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
My invention relates to printing presses and relates more particularly to the tympan cylinder portions thereof, the invention havingifor its object the provision of mecha-- nism which will tighten the tympan upon its cylinder without permitting material circumferential creepage of the tympan. l
I will explain my invention fully by reference to the accompanying drawing show ing two embodiments thereof and in Which-,-
Figure 1 is a sectional view on line 1 1 of Fig. 2; Fig. 2 is a sectional view on line 2 2 of Fig. l; Fig. 3 is a detail showing some of the parts of Fig. 1 in another adjustment; Fig. et is a detail view on line 4 4 of Fig. 5; and Fig. 5 is a view in elevation.
Like parts are indicated by similar characters of reference throughout the different figures.
p The cylindrical body portion a of the tympan cylinder is provided with the usual end plates l) having supporting shafts o, all 1n accordance with usual or desirable practice. The cylindrical portion a is provided with the usual or suitable longitudinal slot or gap d.
Referring rst to Figs. 1 to 5 inclusive, a reel rod e is located in gap d and extends longitudinally of the cylinder, this rod bev ing journaled in the cnd plates c. The reel rod is narrower than the gap and is mounted between and spaced apart from the longitudinal sides of the gap whereby access may readily be had thereto for the purpose of introducing the ends of the tympan to the slot in the reel rod. Said rod is preferably located nearly central within the gap d and well within the periphery of the cylinder. The tympan f, which serves as a basis for overlayin and cutting out to improve the quality of the press work, is of any usual or suitable formation, its ends` being passed Specification of Letters Patent.
Patented Feb. 9, 1915.
serial No. 776,216.
through a slot in rod e, a packing g intervening between the tympan and the cylindrical wall a. As viewed in Fig. 1, the rod e may be turned in a counter clock-wise direction by means of a pin when inserted within the radial holes lz in the rod e; Return movement of the rod e is prevented by means of a well known brake or clutch mechanism including balls t' pressed inwardly against the rod e by springs k held in place by abutment screws Z. A tapered pin inserted in holes fm, will lift and release the balls. When the reel rod is turned, it tightens the tympan upon the tympan cylinder, but in so doing it simultaneously pulls with equal force in opposing and approaching directions upon both ends of the tympan (rather than upon both ends in the same direction as hitherto) whereby the tympan is tightened upon its cylinder without causing material circumferential slippage of the tympan with respect to its supporting cylinder. The preparation of the tympan cylinder for the improvement of the press work is thus, by means of my invention, not marred by tightening the tympan, though the invention is not to be limited to this utility.
It will be observed that the ends of the tympan initially have engagement with diametrically opposite sides of the single reel rod, since the ends of the tympan are passed in opposing directions into the slot in the rod. By this arrangement the ends of the tympan are immediately drawn toward each other in opposing directions when winding movement 1s initially imparted to the reel rod, the end portions of the tympan being tangential with respect to the diametrically opposite portions of the reel rod.
While I have shown and particularly described the preferred construction embodying my invention, I do not wish to be limitedA gap and which is mounted between and tions upon Winding movement being impartspaced apart from the longitudinal sides of ed to the reel rod.
