H. A. W. WOOD PERFECTING WEB PRESS Original Filed 1919 Patented June 1, i926.
nirs n stares PATENT HENRY A. WISE WOOD; OF NEW YORK, N, Y., ASSIGNOR. TO VTOOD NEWSPAPER MA CHINERY CORPORATION, OF NEW YORK, N. Y., A CORPORATION OF VIRGINIA.
Paarncrme was ranss.
A plication filed September 25, 1919, Serial No. 326,214. Renewed December 6, 1924.
This invention relates to a perfecting web press. The principal objects thereof are to provide a construction of rotary stereo typing newspaper printing press that will be so inexpensive to build and maintain and will occupy so little space that it can be adopted by small newspaper plants which are now prevented from using the machines now on the market on account of the expense entailed and the space taken up.
These objects are secured according to this invention by providing a compact arrangement of the two printingcouples and associating with them an inking mechanism taking its ink from a single fountain and adapted to ink the plates of both couples; and also providing a web turning mechanism located conveniently and substantially symmetrically with respect to the couples to turn the web. This permits of the location of these several elements on a machine frame not much longer than that ordinarily required for the printing and inking mechanism for operating on one side of the web only.
By the use of a single fountain for inking both sides of the web the cost of the mechanism is out down very materially and considerable space is saved as stated. Furthermore, only one half of the attention is required for the regulation of the fountain. The amount of gearing, number of inking rolls, journals ant adjustments is also inaterially reduced, and by the central location of the inking and turning mechanisms the frame can be constructed in a comparatively inexpensive mannierl The invention also involves other objects and advantages as will appear.
Reference is to be had to the accompanying drawing which is a sectional view of a printing machine frame constructed in accordance with this invention with the printing mechanism shown. largely in a diagrammatic form.
In the form in which the invention is illustrated herein the mechanisn'i is mounted on a frame 10 which provided with bearings for the mechanism described below, and these bearings are located in such a way that the frame itself is comparatively short and takes up very little space as will appear.
At the top of the frame proper it is provided with a turning bar frame 11 which is arranged horizontally in the form' shown and extends a considerable distance on both sides of the main frame. This, however. does not increase the space required for the machine for reasons which will appear.
The web roll 12 is mounted at one side of the frame 10 under one overhanging part or projection of the turning bar frame llso that as stated above the space occupied by the latter does not really increase the length of the press on this side, as'space has to be provided any wayfor the web roll. The web TV passes from the web roll over a bending roll 13 and into the bite of the first printing couple comprising the impression cylinder 1% and plate cylinder 15. The web, printed on one side as will be obvious, then passes up and back over a bending roll 16, to a long angle bar 17 over the well-known bay-window roll 18, back over the second angle bar 19. The web is thus turned over and it then passes over; bending roll 20 down to the otherprinting couple, going around the inipression cylinder 21 and being engaged by the plates on the second plate cylinder 22 and passes to slitting rolls 23. The perfec ted web is shown here being slit in two,- the front half going over the usual short angle bar and compensating rolls Therear half of the web goes over another short angle bar and compensating rolls 26 and both go to the drag roll 27 and thence over the former 28 into the folder in the usual way. 7 H
The angle bars 17 and 19 and roll 18 together with the bending rolls l6 and 20 are supported by the frame 11 over the press frame 1Q,and it will be seenthat the folding mechanism is located partly under the forward projection of this frame 11 so that as stated above the length of the press is not increased by the use of this frame.
It is to be understood of course that another web TV. can be led into the folder in the opposite side from a press like this one. but arranged left-handedly with respect thereto.
The inking mechanism and its relation to the printing couples constitutes an important element of this invention. A single ink fountain 30 is provided having fountain roll 31 which I have shown as contacting direct ly with a large ink drum 32. Ink is taken from this drumby four form rolls and applied to the plates on the two plate cylinlOO ders l5 and 22. Vibratory rollers 34 are provided, and another composition roll 35, which may be vibrated if desired, is placed between the two sets of form rollers. As the printing couples are arranged at or near the top of the inking mechanism, the latter is readily accessible all times.
It is to be understood that whether the ink is distributed directlv from the fountain roller 31 to the drum or through any of the usual mechanisms for this purpose, is not material. It is also possible within the scope of this invention to transfer the ink from the fountain roll to the two plate cylinders through two paths instead of one.
It will be obvious that the two plate cylin de s are located on opposite sides of the inking drum at a convenient distance apart, and that the placing of the two plate cylinders here adds but very slightly to the length of a machine that Would be required for one only.
The two impression cylinders are spaced a little closer together than the plate cylinders, so that they do not add anything to the length of the machine, and furthermore, permit of conveniently leading the web in and out at an inclination so that it passes directly to the slitter 23.
From What has been said it will be understood that the simplicity, reduction in eX- pense and space, and reduction in the cost of maintenance and repairs mentioned above are all obtained by means of this invention.
By having only one fountain the operator spends only half the time heretofore necessary for fountain regulation in running a perfecting press. The adjustments necessary on the rest of the mechanism are also materially decreased as well as the bearings and gearing to be kept in order and lubricated, and thus the cost of this type of press and its care and maintenance are so materially reduced that its use may be extended into small plants not heretofore able to use them.
Although I have illustrated and described only one form of the invention I am aware of the fact that modifications can be made therein without departing from the scope thereof as expressed in the claims. There fore I do not wish to be limited to all the details of construction shown or to the specilic arrangement and number of the various elements, but what I do claim is 1, In a perfecting web press, the combination with a pair of printing couples arranged to print on both sides of and perfect a web, of a single inking mechanism located and arranged to supply ink to both couples constantly and directly and without interruption.
2. In a perfecting web press, the combination with two printing couples, each consistingof a plate cylinder and an impression cylinder, the two impression cylinders being arranged above their respective plate cylinders and nearer together than the plate cy inders, of an inking drum arranged below said couples about half-way between them, and form rollers for inking them from said drum, whereby the inking mechanism is readily accessible.
In a perfecting web press, the combination with a pair of printing couples for perfecting a web and means for leading the web from the upper cylinder of one couple, of a web turning means engaging the web after it leaves the first couple and turning it. means for directing the turned web back against the upper cylinder of the other couple, and a unitary inking mechanism for dclivering ink to the plate cylinders of both of said couples.
In a perfecting web press, the combina tion with two printing couples, each consisting of a plate cylinder and an imprcs,- sion cylinder, the two impression cylinders being arranged above their respective plate cylinders and nearer togther than the plate cylinders, of an inking mechanism arranged below said couples and between them and comprising form rollers contacting with both of said plate cylinders for inking them, vibratory composition rolls on the delivery side of the inking mechanism, and a conr position roll between the two sets of form rolls.
5. In a perfecting web press, the combination with two printing couples, each consisting of a plate cylinder and an impression cylinder, the two impression cylinders being arranged above their respective plate cylinders and nearer together than the plate cylinders, means for guiding the web into the bite of one couple from one side, means over said couples for turning the web and guiding it around the other impress-- sion cylinder and out from the second cou ple at an upward inclination, an inking drum arranged below said couples about halfway between them, form rollers contacting with said drum and with both of said plate cylinders for inking them from said drum, two form rollers being arranged for engaging each plate cylinder, vibratory composi tion rolls engaging the drum on its delivery side, and a composition roll between the two sets of form rolls.
6. In a web press, the combination of a frame having means at the bottom for supporting an ink fountain, means above the same for supporting an ink drum in position to take ink from said fountain, means symmetrically located on the opposite sides of said drum but above it, for supporting two printing couples one on each side of the frame, projections on said frame at the top extending beyond the supports for the printing couples, and web turning mechanism carried by said projections for turning the web printed by one couple and delivering it to the. other.
T. In a web press, the combination of a frame having means symmetrically located on the opposite sides for supporting; two printing couples one on each side of the frame, projections on said frame extending beyond the supports for the printinp couples, and web turning mechanism carried by said projections for turning the web printed by one couple and delivering it to the other.
