HOWARD M. BARBER, OF STONINGTON, CONNECTICUT, ASSIGNOR TO C. B. COTTRELL da SONS COMPANY, OF NEW YORK, N.
Y., A CORPORATION OF NEW JERSEY To all whom ft may concern:
Be it known that I, HOWARD M. BARBER, a citizen of the United States, residing at Stonington, in thecounty of New London and State of Connecticut, have invented certain new and useful Improvements in Paste-Fountains for Printing-Presses; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to paste-fountains for printing presses.
The device comprises the usual paste-fountain closed at one end by a paste-roller revolving in the fountain and taking paste therefrom in a manner to supply the paste-sweep or blade at each revolution of the sweep, the edge of the sweep wiping or scraping upon the periphery of the roller and taking from the roller a sufficient portion of paste at each contact. The pastesweep then, as in the usual form, delivers the pastev thus obtained to the web, as, for example, to the transverse margin of every second sheet of the printed web when the sweep meetsthe paper as it is traveling over the top of an adjacent guide roller. Then, in the usual manner, upon every alternate sheet thus supplied with a line of paste there is superposed an unpasted sheet.
My invention comprises especially an arrangement of the parts and an application ofthe gears to insure the revolution of the fountain roller so that it will present a freshpaste covered surface to the paste-sweep every time the sweep contacts with thel roller, and so that the paste-sweep and the web may travel at the same speed and at any desired speed, while the foun-4 tain roller is driven slowly.
In the drawings :-Figure 1 is a side elevation showing part of the frame; Fig. 2 is a view mainly in section on line 2 2 of Fig.` 1. Fig. 3 is a sectional detail.
10 represents part of the frame of a printing press. 1l is the printed web of paper which passes between the guide roller l2 and the idler 13, thence over the idler 14 to the guide roller 15. The guide roller 15 bears a shaft 16 which is journaled in the frame l0. Keyed to the outer end of the shaft is a geanwheel 17 which may be driven inany manner by pulleys and intervening gears and similar familiar' devices.
18 is a gcar-wheel keyed to the shaft 16. The pitch line of the gear-wheel 18 coincides with the periphery of the guide roller 15.
19 is a paste-fountain secured as indicated at 20 to the `frame 10. Within the paste-fountain and closing one end of it, is a paste-roller 21, which is journaled on a shaft 22 to which is secured at one end a gear-wheel 23.
24 is a shaft journaled in the frame 10 and having positively and continuously, but

Patented Sept. 1'?, 1907.
secured to it a paste-sweep or blade 25. Keyed to one end of the shaft 24 is a gear-wheel 26. The shaft 24 is journaled at one end in a hub or boss 27. Upon the outer end of the hub or boss 27 is secured a gear-wheel 28.
29 is a gear-wheel which turns freely on the boss 27, and which carries on its hub a gear-wheel 30 meshing with the paste-roller gear-wheel 23.
The gear-wheel 26 near its periphery bears a stud 3l. Upon the stud 3l is mounted a gear-wheel 32 and upon the hub of the gear-wheel 32 is secured the gear-wheel 33. The gear-wheel 32 meshes with the gear-wheel 29, while the gear-wheel 33 meshes with the gear-wheel 28.
The gear- wheels 28, 29, 32 and 33 are arranged to form a differential gearing. That is to say, for example, the gear-wheel 28 has twenty-nineteeth and the gear-wheel 29 twenty-eight teeth, while the gear-wheel 32 has twenty teeth and the gear-wheel 33 twenty-one teeth. This arrangement of `differential gearing, or an equivalent one, will cause the gear-wheel 30 to rotate slowly in the direction indicated by the arrow in Fig. 1, and this will in turn drive the fountain-roller slowly but at sufficient speed to cause it to present a fresh paste-covered surface to the paste-sweep every time the paste-sweep 25 passes the fountain and comes in contact with the paste-roller 21. As it has been previously stated, the pitch line of the gear-wheel 18 coincides with the periphery of the guide-roller l5. It will also be observed that the circle described by the pastesweep 25 coincides with the pitch line of the gear-wheel 28. This relation of the gear-wheel 18 and the guideroller 15 and the gear-wheel 26 and the paste-sweep 25 will give the same speed to the web as it passes around the guide-roller 15 as the paste sweep will have in action.
At 19 l have indicated an adjustable knife or blade by which the thickness `of the film of paste carried by the fountain-roller may be regulated.
An ordinary paste-fountain in which the paste-roller operates at the same surface speed as the web and the paste-sweep may be practicable at medium speeds, but on high speed machines the fountain-roller rotates so rapidly that the paste soon loses its adhesive qualities and furthermore the paste-fountain, however carefully constructed, will leak when the paste-roller is driven at such high speeds. This difficulty cannot be effectively cured by intermittent rotation of the fountain-roller, because in such intermittent motions there will be occasional skips when the sweep will pass over the same surface of the roller from Vwhich it has already taken paste, or the fountain-roller will be made to rotate further than intended so that the pastesweep will take an excess of paste, which will be thrown from it by centrifugal force, to the injury of the publication, and frequently in these constructions it will be found that the paste-sweep with its wiping con- 1 10 tact will move the fountain-roller ahead so that the paste-sweep Will receive too much paste on its next revolution. In the device illustrated by this application these objectionable features are obviated by driving the fountain-roller continuously but very slowly and by driving the fountain-roller positively so that it never may remain inoperative during any revolution and so that it may not be driven ahead by Contact with the paste-sweep.
The fountain-roller driving gear is so proportioned that the surface oi the fountain-roller travels just the t required distance to supply suihcient but at no time an excess oi paste to the paste-sweep.
Having fully described my invention what I Claim is: l. n
l. In a paste-fountain for printing-presses, the combination of a paste-roller and paste-sweep, with means for operating the paste-sweep throughout its rotation at the same speed as the web, and means for driving the pasteroller at a lower speed.
2. In a paste-fountain for printing-presses, the combination of a paste-roller and paste-sweep, with means for operating the paste-sweep at the same speed as the web, and means for positively and continuously driving the paste-roller at a lower speed.
3. In a paste-fountain for printing presses, the combination of a paste-roller, paste-sweep and web guideroller, a set of gears driving the guide-roller and pastesweep synchronously and a differential gear for driving the pasteroller slowly whatever the speed of the web and paste-sweep.
'4. In a paste-fountain for printing-presses, the combination of a paste-roller and a paste sweep, means for operating the paste-sweep at a constant speed and means for operating the paste-roller at a constant but slower speed.
l In testimony whereof I affix my signature, in presence of two Witnesses.
