AUTOMATIG 'DBYING DEVICE EOR INKE SHEETS Application filed June 5, 1930. Serial No. 459,316.

which will permit the sheets to descend by ygravity in the form of a plurality of superposed and spaced sheets until one by one they all to a, delivery point ,which may be a tray. rlhe characteristic of the device is that the sheets have a gravitational movement from an upper point to a lower point and in such movement are given sucient time for the ink to set, so thatwhen the sheets are finally de sited one in contact with the other the in will not blur or o'set on the reverse side of the succeeding sheet. A further object of the invention is to provide a device of this character which shall he simply constructed, and capable of operation for long periods without derangement.

The invention will be described with reference tothe drawings in which Fig. l is a view in side elevation of an embodiment, with a side plate brolren away, the device being ep lied to e type of stencil machine so as to e driven' from thev driving means of the latter.

Fig. 2 is a plen view of the device. Fig. 3 is e. horizontal section on the line 3--3, Fig. i. llig. d is an enlarged view in elevation of the spiral plates and bladeshafts.

Fig. is a "fragmentary elevation of the blade-shaft.

Fig. 8 is a diagrammatic view showing a method oi3 assembling the blades by overlapping their edges. i

Referring to the drawings, l have therein shown a rectangular frame comprising lower horizontal frame members l, of* tubing, connected at their ends by elbow joints 2, each joint having an upwardly extending sleeve-like member 2m, to receive a vertical frame member 3. Vertical frame members 3 at the top of the frame are received within depending sleeves of four elbow connecting members d which members 4 receive the four tube-like upper horizontal frame members 5. Held by opposed sets of sleeves 6 on lower frame members l are cross iframe members 7. Each iframe member 7 has keyed thereon spaced sleeves 8, (Fig. 1) each sleeve having a vertical, recessed extension 8m, a'ording a bearing seat for a blade-shaft 9. Keyed to each bladeshaft at the top of the vertical extension 8m of sleeve member 8, is a pinion 10. rlhe pinions are connected for simultaneous rot-ation by means of two inter-meshed idler pinions l1. rlhese pinions are supported from cross frame members l2, each frame member l2 receiving a sleeve 18 (Fig. l), the sleeve having a vertical, recessed extension adapted to receive a screw-stud 14C (Fig. 3), threaded into said vertical extension, such construction being well known in the mechanical arts, and not requiring detailed illustration or description.

The upper ends of three of the blade-shafts `9 are received within the lateral apertured extensions 15m of sleeves l5 (Fig. 2) mounted upon cross frame members 17, which latr are at one end secured to one of the upper frame members 5 and which at the opposite end are bent upwardly and attened at 17m. These iiattened ends are apertured so that they may be bolted to a bar 18, carried by the stencil machine A, when the device is particularly designed for such application.

rl`he fourth of the shafts 9 is mounted in the manner shown in detail in' Figs. 2 and 6.

Carried by one .of the upper frame members 5 is a bracket 19. Bracket 19 is also su ported by shaft 17, a sleeve 19m on the brach` et receiving the letter shaft. I Bracket 19 is formed with a vertical bearingsleeve 20 which receives said fourth shaft 9 and the shaft. carries a horizontal bevelled gear 2l. in mesh with a bevelled gear 22 on e. stub shaft 23. Stub shaft 23 is supported in spaced bearing bosses 24,- and the shet is provided with a sprocket wheel 25 which receives a chain 26, leading to a driven gulley 27 (Fig. l) of the stencil machine In the present embodiment each of the blade-shafts 9 is cut with e spiral 'groove 28 to receive a plurality of blades 29, the blades being shown in plan view Fig. 2. Each blade is made as a disk cut -trom axis to eriphery, and at one side oi the cut gradua y deflected, axially, until that portion ont the blade at the opposite side of the cut lies, when the blade is horizontal, at a lower level, and exactly in register with the uppermost section oi a lower blade to iorm a unit cfa spiral. lf the blades are made suciently stid, and the edges are truly formed so that the upper edge ot a blade will come into exact 'register with the lower edge of an upper blade, and the lower edge into register with the upper edge ot" a lower blade, the meeting` edges of a plurality of blades may be held in abutment without brasing, welding, or other means o uniting them.

Fig. 2, the blades are shown with arrows thereon indicating the direction o" movement, and it will be seen that the blades have such direction that the paper ted thereon has a tendenc to move to the rear oli the device, or in ot er words in ythe direction o' feed ci the stencil machine, printing press, or other ink applying device.

At the top 'of the machine and suitably mounted, as for exam le, to the sleeve entensions l, may be isposed opposed bars 30 'which may support a rectangular trame, of which a fragment is shown at 3l (Figs. 2, 5 and 6), the frame carrying a lass panel 32, throu h which the action oi t e machine may be o served from above;

n Fig. l, l have indicated three successive positions oi a sheet fed into the device by the stencil machine, the sheet being indicated at b. The sheet is thrown forwardly by the feeding mechanism of the stencil machine A, the said movement of the sheet carrying it into the drying device, the forward and.

downward movement of the sheet carrying it into contact with the topmost blades. The

rotation of the blades will be in synchro-l nism with the feed of the stencil machine, as will be understood trom the fact that driving pulley 27 of the stencil machineis directl-y connected b chain 26, with the driving mechanism of t e dryin device and the blade shafts are intergeare The s nchronism may be such that each sheet wil fall upon the topmost blades when the upper edge of the spnal or first blade is in a position onehalf revolution from that shown in Fig. 2 of the drawings. As the blades rotate in the direction of the arrows, the sheet will be caused to pass by gravity downward until it is finally ropped into the tray B.

I have discovered that it is unnecessary that the edges of one blade abut the lower edge of a top blade, and the upper edge of a bottom blade, inasmuch as the lower edge of one blade may slightly overlap the upper edge'of an underl mg lade throughout the assembl on a bla e shaft, particularly when the bla es are stamped out of relatively thin theatres sheet metal.- In fact, this overlapping arrangement may serve of itself, as a method of separatin the blades the required distance apart, alt ough such means ma be supplemented by washer-like spaces -hot shown) inter osed between the blades, and surrounding t e blade shaft.
