CYLINDRICAL NEO'S'TY'L'E.

SPECIFICATION forming part of Late. Patent No. 637,764, dated. I N'ovember as, 1899.

Application filed June 3,1898. Serial No. 682,422. (No model.)

T0 all whom it may concern:

Be it known that I, JOHN W. CAMPBELL, of New York, (Sea Oli ff,) in the county of Queens and State of New York, have invented an Improved Cylindrical Neostyle, of which the following is a specification.

Referring to the accompanying drawings, Figure 1 is a rear elevation of my improved neostyle. Fig. 2 is a side view of a form of severing mechanism contained in the machine, a portion of this figure being taken on line or x of Fig. 1. Fig. 3 is a front end view of the machine shown in Fig. 1. Fig. 4 is a top plan view of the machine. Fig. 5 isa front side elevation. Fig. 6 is a transverse sectional detail at line y y of Fig. 5 of the swinging frame which supports the platen-roll of the neostyle. Fig. '7 is a rear side elevation of a portion of the machine, the severing mechanism being removed for greater clearness. Fig. 8 is a lengthwise central section of the machine with the severing mechanism removed, on line 2 z of Fig. 4.

The cylindrical neostyle (and comparable machines) prints from a stencil-like impression-roll on tissue or other thin paper, and where large numbers of copies are wanted for immediate use much difficulty has been encountered in dryingthe copies rapidly enough for desirably-prompt distribution.

One object of my invention is to blot or otherwise get rid of the fresh ink on the copies as fast as they come from the printing-rolls, and a second object of my invention is to sever the copies from a continuous web as fast as the printed copies are made apparently dry in the machine.

My invention consists of the combinations hereinafter claimed.

In the drawings illustrating the principle of my invention and the best mode now known to me of applying that principle, 1 represents the usual stencil-sheet of the cylindrical neostyle, and 2 the gear at the end of its impression-cylinder, whereof the stencil 1 is a part. Theink-roll 3 is mounted as usual and in a manner and in connection with devices too construction of the neostyle proper, and 4, 5,

and 6, respectively, represent the driving-gear of the impression-cylinder,the pinion meshing therewith and rotated by the crank, and the crank. It will be convenient to refer to the handle side of the machine as its front side. The shaft7of the usual platen-cylinder is provided with the bevel-gear 9. Shaft 7, as usual, carries a gear 10, which meshes with an end gear2 of the impression-cylinder. The stencil 1 extends only part way around the impression-cylinder-from cross-bar 11 to cross-bar 12. Bed 13 extends, as usual, on both sides of the platen-roll on shaft 7 and in my improvement is extended between the blotting-roll 14 and its cooperating feedroll 15, which is mounted on transverse shaft 16 at a suitable distance from the shaft 7and carries a bevel-gear 18, which meshes with a bevel-gear 17 on shaft 19, which extends lengthwise of the machine and carries a bevelgear 20, with which the bevel-gear 9 (on shaft 7) meshes. As web 21 is printed and fed from between the impression-rolland platenroll its free end is led (by the operator) between the blotter-roll 14 and cooperating feed-roll 15, the two sets of rolls-the impression-roll and platen-roll and the blotter-roll 14 and feed-roll 15-being geared to rotate at the same speed. These two sets of rolls are driven by power applied to one of the printing-rolls, as by handle 6 on the impression-cylinder, and through the interworking gears 9 and 20, shaft 19, and interworking gears 17 and 18. Roll 14 is faced with blotting-paper or other absorbent material, and the printed portions of web 21 (of tissue or other suitable material) are blotted as fast as printed and so made ready for mailing or other use. When the blotting-paper does not serve to absorb the fresh ink rapidly enough,

I heat one or both rolls 1 4 and 15 by introducing any suitable heater, such as a gasfiame 22 within hollowshaft 22 of blotterroll 14 or within the shaft 16, which may be made hollow for this purpose. Ordinarily the blotter-cylinder will do the work of absorption without the heater, which may be of any suitable kind-gas, oil, or electric, as desired. It is customary to have the platenroll movable toward and away from the impression-roll, as is well known to all skilled 'in the art, and I consequently mount the journals 23 of shaft 19 011 one of the swinging side bars 24, through which the shaft 16 loosely passes. (See Fig. 6,) Shaft 16 isjournaled in the vertically-adjustable boxes 25, mounted in guideways 26 in the side frames- 27,'which are here shown as connected to the usual side frames 28 of the neostyle. These journal-boxes are supported on screws 29,

which serve to press the blotter feed-cylinder 15 toward its cooperating blotterroll 14. Shaft 7 is journaled inand near thefree ends of the swinging side bars 24 24, the free ends of these bars being pulled toward the impres I adjusted to be pushed away from the impression 7 roll (or stencil carrying cylinder) by means of the cams 31, which are mounted in side frames 28 and work on the ends 32 of the swinging side bars. platen-roll 7 and blotter feed-roll 15 is'desirable in cases of variation in thickness of stock and for obtaining desiredpressures between the platen-roll and stencil and between the blotter-roll and its cooperating feed-roll 15. The rolls 7 and 15 may be covered or faced with anysuitable material, and the absorbent sheet 14 is intended to be renewed as fast as blurred by the absorption of ink. I

I As the printed and blotted web issues from between the blotting mechanism, consisting, essentially, of two members preferably, but

not necessarily, in the form of rolls 14 and 15,-

. the web may be severed by shears in the hands of the operator; but, if desired and as I prefer, an automatic severing mechanism may be employed. In thedrawings I show one of many mechanically-possible formsof severing mechanism. (See Figs. 1, 2,

3, and 4.) On the shaft 33 of the blottercylinder (the shaft being jonrnaled in side frames 27) I mount a cam 34, the high point 35 of which engages rod 36 to actuate the mov-,

able member of the severing mechanism at the instant the printed and blotted section of the web issues from rolls 14 and 15. Rod '36 is mounted vertically in bearings 37 on side frame 27 and is held up. by a spring 38 between the lower bearing 37 and acollar 39 on the rod. The lower end of the rod is loosely connected with the lever 40, pivoted at 41 to the. frame of the neostyle; The forward end of the lever engages the movable severing member 42 and moves it toward and away from the stationary member 43, which extends transversely across the machine with its upper edge in theplane of the bed 13. As the high'point of the cam moves out of engage ment with the rod the spring 38 pushes the rod upwardly, so that the latter pulls up the 'rear end of the lever 40, throwing down the front end of the lever and moving cutting member 42 away from stationary cutting member 43. I 7

The adjustability of the The machine above described may be alteredin many of its mechanical features without departure from my invention.

My improved neostyle is especially useful in oflices from which it is desired to send, at certain business hours, large numbers of reports speedilyafter the information therein is obtained and with such celerity that there is not time for, the printed sheets to be dried in the ordinary way. r 7
