SPECIFICATION forming part of Letters Patent No. 387,249, dated August 7, 1888.

Application filed July 19, 1857. Serial No. 244,713. (No model.)

To all whom, ib may concern:

Be it known that I, ANDREW O. Nnsrr, a citizen of the United States, and a resident of Newark, in the State of New Jersey, have invented a new and useful Improvement in Cylinder Printing-iliachines, of which the following is a specification.

This invention relates to means for adapting cylinder machinestoprintenvelopes,ea1ds, labels, and the like.

The objects of the invention are to enable each operator to `feed the machine with both hands sinniltaneously, so as to introduce the envelopes, cards, or sheets of paper two ata time, and at the same time to insure neatlyregistered work, and to so deliver the same as to facilitate taking the printed work from the machine. With two operators one machine will thus printfonr envelopes, cards, or sheets at each operation and deliver one hundred or more per minute.

The invention consists in certain novel conibinat-ions of parts, and in special devices for forming the same by attachments to an ordinary cylinder printing-machine, as hereinafter set forth and claimed.

For clearness the following description will be Confined to an ordinary machine provided with attachments, as aforesaid, and the work will be mentioned as e-nvelopes.7

Three sheets of drawings accompany this specification as part thereof.

Figure l of the drawings represents a vertical longitudinal section of an ordinary cylinder printing-machine provided with my attachments. Fig. 2 represents a perspective view of a portion ol' the feed-table, showing the attachments thereto. Fig. 3 represents a vertical section on theline r r, Fig. 2. Fig. et represents a perspective view ot" the deliverytrough with a portion ofthe near side broken away to expose parts behind. Fig. 5 represents a vertical section on the line y y, Fig. 4., Fig. 6 represents the rear portion ot' the machine represented b y Fig. l, with certain preferred substitutes in place of some of the devices; and Figs. 7 and 8 are perspective views showing the respective delivery-trough bolsters and their appurtenances, as represented in Fig. 6.

Lilie letters of reference indicate corresponding parts in the several figures.

T represents the feed-table, C the cylinder, and B the bed, ofthe machine proper. F F2 F3 represent fixed portions of its frame; G, Fig. l, one of the grippers carried by the cylinder; G', the ordinary front gage, and S a shield employed on some machines. The ordinary delivery apparatus is detached.

The remainder ofthe ordinary parts of the machine are omitted in the drawings to avoid obscuring the attachments, which will now be described.

Upon the feed-table T, I mount a double feed-guide, F. (Shown in detail in Figs. 2 and 3.) The guide proper consists of a wide middle gage, c, and two side gages, c?, parallel with each other and with the line ot' feed, each side having a wide tiange and the middle gage a pair of such iianges, which together form in each half of the guide a bottom, b, which is adjustable in width. For adjusting the guide to fit envelopes of a given size a right-and-left screw, S, is combined therewith, its nuts c being attached to said side gages, a?, underneath the guide, and its swivel-bearing d to said middle gage, u., between a pair of flanges on the screw at mid-length. A square, c, at one end of the screw provides for turning it by means of alley. Both side gages are thus simultaneously and equally adjusted toward or away from the middle gage with the requisite nicety.

For giving the feed-guide F an inclination greater than that ofthe table, so that the envelopes shall slide freely therefrom, a bolster, B', is interposed between its rear end and the table T; and to provide for bodily adjusting the guide laterally said bolster is arranged transversely with reference to the guide, and is made in two parts dovetailed together, so that the upper part slides longitudinally ofthe lower, as clearly shown in Fig. 2. The lower part is affixed to the table by a pair of thumbserews, f, inserted from beneath the table.

The guide F is attached to the upper part of the bolster B by a screw, g, for example, passing downward through the middle gage, a, into and through said upper part of the bolster, so that its lower end acts on the lower part to lock the guide in its different positions. A groove7 lz., in the top of said lower part receives the end of the screw g, so as to keep it from roughening the frictional sur IOO faces of the dovetail. rlhe head of the screw g should be sunk to or below the surface of the gage a, and the ends of the gages should be rounded, as represented, so that there shall be no cutting-edges for the hands to come in contact with in their rapid movements.

To receive the printed envelopes as they are released in successive pairs by the gri ppers G at X, Fig. 1, I substitute for the ordinary delivery apparatus a double deliverytrough, D, (shown in detail by Figs. 4, 5, 7, and 8,) and accessories thereol` shown in these figures and in Figs. l and 6. The trough proper has a thin central partition, t', which in working position is in line with the center line of said middle gage, c, ofthe feed-guide F, and sides i2, which ilare somewhat beyond said side gages, a2, at the receiving end of the trough, so that the envelopes shall be sure to drop between them. The greater width of said middle gage as compared with said partition causes the envelopes to drop clear of the latter. Beyond a point indicated atj in Fig. 4- the sides i2 are parallel with the partition t'. The bottoms k of the respective compartments of the trough, like those ofsaid feed-guide, are formed by overlapping wide anges integral with said partitions and sides, so as to be adjustable in width, as clearly shown in Figs. 5 and 7.

For adjusting the delivery-trough and supporting it in ei'i'ective position, a pair of divided bolsters, B B3, are attached to the frame of the machine. As regards the adjustment of the trough as to width and lateral position, these bolsters are all substantially of the construction represented at B2 in Figs. 4 and 5. (See, also, Figs. 7 and 8.) They are divided horizontally, like said bolster B,with a longitudinal dovetail uniting their parts. The upper part of each of these bolsters B42 B3 is further subdivided, a section being attached to each part of the trough, as shown in Figs. 5 and 7, and the respective parts are independently clamped in position upon the lower part of the bolster by thumb-screws Z on, inserted in convenient positions. Grooves n, Fig. 4, may receive the ends of the screws, as in said bolster B. Said bolsters B2 B3 in the arrangement represented by Figs. l, 4, and 5, Sheets l and 2 of the drawings, are attached, respectively, to fixed parts F2 F" of the frame of the machine, within the same and at its back, as shown in Fig. l. The receiving end of the trough should be close to the cylinder C, as here represented-that is to say, within about one-quarter of an inch from the periphery ot' the make-ready. Slots o and ordinary tongueand-keeper connections, p, Fig. l, provide in this arrangement for adj usting the trough toward and away from the cylinder. Said slots o are formed in the upturned ends of said bolster B2 and serve to receive the bolts which attach this bolster to the frame of the machine. The respective parts of said connections p are attached to the upper sections of said bolster B3 and to the bottoms of the trough D, respectively, one set to each section, and each keeper is provided with a setscrew, p.

Preferred devices for adjusting the deliverytrough D toward and away from the cylinder C more readily and with greater nicety constitute the principal modiiications illustrated by Figs. 6 to 8, inclusive, Sheet 3.

, To coact with and supplement the rear bol ster, B3, Figs. 6 and 7, a horizontal bar, B, is attached to the back of the frame of the machine. A saddle, B5, is fitted to said bar, and an adjusting-screw, BG, connects the saddle and bolster, which are provided, respectively, with a swivel-connection, 85, and a screw-nut, as, to coact therewith. A suitable hand-wheel or head, h, provides for readily turning thescrew. The respective upper parts of the bolster are attached directly lo the corresponding trough parts, as aforesaid, while the trough is free to slide on said saddle B5, and is so moved back and forth by turning said screw B6.

To permit the inner bolster, BZ, Figs. 6 and 8, to move with the trough D when it is so adjusted longitudinally, and to provide by the same means for adjusting the receiving end of the trough vertically to a suiiicient extent to keep it correct as to height and angie, said bolster B2 is supported by a pair of link-rods, L2, from a horizontal rod or round bar, R2, at the back and near the top of the frame of the machine, and the lower ends of said link-rods are swiveled, screw-threaded, and provided with wrench-squares s2, as shown in Fig. 8, to coact with screw-nuts n2, which are swiveled to the respective ends ofthe lower part of said bolster B2. Said link-rods are also connected with said rod It by eyes e?, Fig. 8, so as to turn freely thereon. The lower ends of said link-rods Ll turn in their swivels s3, Fig. 8, when the wrench is applied to said squares s2 to adjust the receiving end of the trough vertically, as aforesaid, and the link-rods turn on said rod R2 and the nuts a turn or swivel when the relative angles of the trough and link-rods are changed by so adjusting the trough or otherwise.

To provide for readily supporting the delivery-trough Dv out of the way in converting the machine for wide work, or when the trough is not required, the upper sections of said linkrods L2 are made hollow above said swivel s3 and of sufficient length and diameter to permit the link-rods to telescopa and are pro vided with set-screws s4, Fig. 8, or equivalent devices, by which to fasten the linkrods in compacted shape when the trough is lifted out ofthe way, so as to retain or aid in retaining the latter in its elevated position.

For Aarranging the printed envelopes on edge within the delivery-trough, its bottom k, at its receiving end, is inclined at an angle of about thirty degrees, as indicated in Figs. l, 4, 6, and 8. Openings q (best seen in Fig. 4)' are formed in the respective compartments at this end, and oscillating turners T', pivoted at the angle of the bottom 7c, work through said openings to turn the successive IIO IZO

pairs of envelopes on edge. Detentsr, attached to the partition t', and sides i2 at said pointy', Fig. t, prevent the return of the envelopes with the turners, and with the aid of an opposing sliding support, as s, Fig. l,within each compartment, the envelopes are thus kept in compact ranks ready to be transferred directly to `boxes or bundles.

To keep the envelopes from getting beneath the turners T', should a pair drop before the return of the latter, the turners are made with segmental outer ends, t, which,when the turners are up, as shown in dotted lines in Fig. 1, form temporary envelope-supports within the trough. To provide for lifting each envelope from al' or near each edge as well as at an intermediate point or points, it is necessary to make the turners T adjustable with reference to the width of the respective compartments. Each compartment is consequently provided with three (or, it may be, two or more than three) turners having hubs Iitted to a horizontal shaft, S2, common to all, upon which they are independently adjustable by means of set-screws a. To insure their alignment and their simultaneous actuation, the turners are further connected with said shaft by a spline, o, Figs. l and 6. For actuating said tu rners,said shaft S2 is provided with a flanged pinion, P, which is engaged by a rack, R, Figs. l and 6, which is coupled to an upright lever, L, at the back of the machine. Said lever is pivoted at its lower end on a hingelrod, I-I, attached to the door. At its upper end it is connected to the frame of the machine by a retractingspring, S3, which tends to keep the turners T' in their lowered position. (Represented by full lines in Fig. 1.)- A second spring, S, is stretched between the lever L and rack R, so as to keep said rack in mesh with the pinion P between the ianges of the latter, and a keeper, K, Figs. 6 and 8, may preferably be attached to the adjacent side of the trough D, and connected by an eye, e,with

the shaft S2, the latter being` made to protrude sufficiently, so that said pinion P may also be attached by said spline c, and to preclude the escape of the rack from between the pinions flanges. Forautomatically working said lever Lto lift the turners T at the proper moments, the rear end of the bed B is provided with a tappct, `10,'Fig. l, and said lever L is provided with an elastic cushion, m, as ablock of rubber, in line with the tappet w, which cushion is held within a socket, i, carried by the lever, and is projected more or or less by a screw, z. The effective movement of thelever (illustrated by dotted lines in Fig. l) is varied by this adjustment, so that the motion transmitted therefrom through the rack R, pinion P, and shaft S2 shall swing the turners T to the proper extent to leave the edges of the envelopes behind the detents r without increasing the motion of the turners to an unnecessary cxtent. The return movement of the lever is limited by a suitable stop-the bolster B3, for eXample-so that the turners are supported with theirl upper edges at or immediately below the inclined bottoms of the receiving end of the trough, as indicated in full lines in Fig. 1, so as to support the next envelopes and to turn them without loss of time.

The operation as a whole is as follows: The form being in place on the bed B, the cylinder G made ready and revolving, as represented by the arrow a in Fig. l, and the attachments adjusted as described, each operator takes the blank envelopes from the table T, two at a time, and places them in the respective compartments of his feed-guide F with their lower edges against the front gage, G. Here they are simultaneously caught by the grippers G and carried into printing contact with the form and away therefrom to the point X, Fig. l, where they are dropped, as aforesaid, upon the inclined bottoms of thereceiving end of the delivery-trough ll), whence they slide upon the turners T. At the end of the next succeeding printing operation the effective motion of the lever L, derived from the bed B, as aforesaid, turns said envelopes on edge behind the detents r and against the sliding supports. Immediately thereafter another release of envelopes by the grippers G takes place; but before these can reach the turners T' the latter, at ordinary working speed,have been returned to theirlowered position by the return of the bed B and the instantaneous action of the retracting-spring S3, through the lever L, rack R, pinion P, and shaft S2. The envelopes last dropped are turned on edge at the end of the next printing operation, and thus the process goes on.

The bed B is shown in full lines in Fig. l as if moving outward, as indicated by the arrow b, preparatory to a succeeding effective movement in the reverse direction. (Indicated by the arrow c.) It is shown at the end of this effective movement in dotted lines.

I have described the respective parts as constructed and attached in thebest waysnow known to me; but I do not limit my claims, hereinafter stated, except as therein expressly provided, and necessary details which are not specified maybe of any approved description. The modifications illustrated by Figs. 6, 7, and S are selected as the basis of my specific claims as to the delivery-trough supporting and adjusting devices.

In some cases the side gages of the double feedguide F may be omitted altogether. The operator wouldthen press the envelopes edgewise against the respective sides of the middie gage, so as to adjust them by this alone in connection with the front gage, G.

Having thus described my said improve ment in cylinder printing-machines, l claim as my invention and desire to patent under this specificationl.
