Application filed September 12, 1905- Rerial No. 278,156.

To all whom it may concer t:

Be it known that I, ERED WArrn, a subject ofthe King of Great Britain, residing at Otl'cy, in the county of York, England, have invented certain new and useful Improvements in Platen Printing-Machines, and of which the following is a specification.

This invention relates to platen-machines for printing envelops; and my object is to provide such machines with an adjustable envelop-container box applicable for the reception of envelo'ps of various sizes, means for automatically feeding the envelo s singly from the said container-box onto t to feedplate, and means for automatically iofl'lthe impression should the feed mechanism he arrangement and combination of devices constituting my invention will be understood by describing the same with referonce to the accompanying sheets of draw- .i'ngs, forming. which similar corresponding where1n 4 Figure Lisa part-sectional side elevation of such parts of a laten printing-machine as are necessary to i lustrate the application of a part of this specification, in numbers of reference indicate parts in each of the figures,

- my improvements, and Fig 2 is a plan of the same. Fig. 3is a sectionahsidc elevation illustrating the fced'mechamsm taking an envelo from the CODt&1I10IbUX,.&T1(l Fig. 4 is 1 a simi ar view illustratingthc feed mechan- 4,) and into i this box the enve Figs. 5 and 6 placed side by side with the flap si e of each ism in the delivery position. are respectively a sectional side elevation and front end elevation of the envelop-com taincr box .detached from the Fig. 7 is a detail view drawn to an enlarged scale.

machine, and

pivoted on I -sists\oi' a main cross-rail,14, fixed on the side eabh end thereof,

; frames '1 of the machine at the front end thereof, which cross-rail 14 carries on its under side abridge-piece 15,ai1ljustable through thumb-screws 15,, while depending pillars 16 16 are fixed to the said cross-rail 14, one at which pillars have their lower ends connected by a cross-stay 17, to l which latter is fixed a-stop or rest 18, which passes upwardly in front of theforemost envelop, and on the pillars 1G 16 a verticallyadjustable base-rail 19 is provided carrying two outwardly-projccting L-shapcd brackcts 20 '20, which latter are adjustable horizontally to and away from each other on the said base-rail 19, while to the foiemost ed es of the L-shaped bracltcts 2H 20 vertical adjustable plates 21 21 are attached. employing this construction of container box the L-shaped brackets 20 20 may be ad justed toor away from each other to suit the width of the envclops to be received, and by adjusting the base-rail 19 on the pillars 16 16 to or away flpm the bridge-piece 15 the depth of the box may also be ad 'usted to suit the depth of the envelo s to he container: therein, while the verticall -ad j ustable plate... 21 21 may be set at the most suitableheight to support the foremost envelo The envelop-container box ust described is inclined or set at an angle to the side frames 1 of the machine, (see F envelop toward the address side.'of the envelop in front of it. The envclo s 22 in the box fall b avity against the xed stop or rest 18, waigi flap of the foremost envelop, while the upper edges of the envelops are located beneath the bridge-piece 15.

The automatic envelop-feed mechanism consists of a'pair; of sprin y fingers 23 23, carried on an arm 24, attac ed to the vibrating or swinging platenfi; which platen moves the said fingers 23 23 in an arc of a circle, so that the said fi ers 23 23 are made to slide up against the ap side of the foremost e1 1-' velop 22, situated in the container-box, and pass beneath-the flap on each side of the stop or rest 18. The springy fingcrs 23 23 are as the said fingers 23 23 move in an arc of a circle they draw the to edge of the envelop engaged clear of the bridge-piece 15 and then pass the said envelop forward. Above the gs. 1,3, and

s 22 are bears against the center of theeach provided with a stiffening-piece 25, and

platen 5 and located on the feed-plate a prcsser-lingers 26 26 are employed to bear upon the fed envelop and retain it in pos1 tion on the feed-plate 2 until laid hold of by the gripper 6, which carries it away to be printed.

\Vhen the platen 5 is in the up position, the lingers 23 23 are in the down position up against the lie p side of the foremost envelop, with their upf er ends innnediately below the edges of the ap of the envelop, (see Fig. 3,) and on the platen 5 swinging into the down position the lingers .23 23 are moved upward in an arc of a circle, which action has the ell'ect of causing the lingers 23 23 to pass beneath the llap of the foremost envelop, draw the top edge of the said. envelop clear of the bridge-piece 15, and carry such envelop forward onto the feed-plate 2, up against the stops 3 3, and beneath the presser-lingers 26 26, (see Figs. 2 and 4,) which lingers 26 26 bear upon and retain the fed envelop until i is laid hold of by the gripper 6 of the platen 5 on the latter again swinging into the up position to carry the envelop away to be printed. (See Fig. 3.) The rising of the platen 5 simultaneously lowers the fingers '23 23 ready to remove the next envelop, so that the envelops in the containenbox are fed singly and automatically onto the feed-plate '2 with precision.

The construction of the springy fingers is clearly shown in the enlarged side elevation at Fig. 7,;in which each linger 23 is provided with a stiliening-piece 25, as hereinbefore describel. By constructing the springy lingers in this manner the fingers ZB 23 them selves are rendered exceedingly flexible, so that during their downward movement against the foremost envelop they yield, as shown in broken lines at Fig. 7, w 1le on the said fingers 23 23 engaging the foremost cn velop to carry it forward the said fingers 23 close against=their stiffening-pieces 2.5, as shown in"l"ull lines at Fig. 7, whereby the said fingers 23 23 are rendered perfectly rigid during their upward movement.

The automatic im )rcssion throwing ofi mechanism consists oi an upstanding bracket 27, fixed on the stud 11, on which bracket at 28 is pivoted a trigger 29, which latter is normally held in the up position (see Fig. l) by means of a spring-pin 30, carried in the bracket 27 between a dependingarm of the trig or 29 and the weighted detent lever 10, whi e a projecting arm of the said trigger 2Q asses between the forked end of a lever 31, provided on a rock-shaft 32, situated across the machine in bearings 33, which rock-shalt 32 also carries a feeler-arm 34, extending centrally over the feed-plate 2, having its free end depending, so as to be capable of passing through an opening 35, provided in the said plate 2. The shaft 32, carrying the forked lever 31 and the feclcr-arin 34 just described, is rovided with a pending arm 36, through t 1e medium of which the said shaft 32 is rocked by a pivoted bell-crank lever-37, operated by a cam 38, situated on a driven shaft 39 of the machine The fecler-arm 341 and forked lever 31 are simultaneously lowered by reason of their own weight and simultaneously raised through the medium of the cam 38 once for each revolution of the cam-shaft 39 to suit the intermittent feed of the envelops, so that as each envelop is fed from the containerboX onto the feed plate 2 by the sprin y lingers .23 23 of the swinging platen 5 t 1e feeier-arm 34 and forked lever 31 are simultaneously lowered, so that the former comes down upon and is supported by the fed onvelop, while the latter comes down into engagement with the trigger 29, but not sulliciently far to operate the latter, when the feeler-arm 34 and taneously raised through the medium of the operating cam mechanism, whereby the said fcelcr-arm 3% is lifted clear of the envelop, so as to allow the latter to be carried away by the gripper 6 on the swinging platen 5. Should the springy lingers 23 "23 fail to feed an envelop onto the feed-plate 2, the feelerarm 34 on being lowered passrs through the opening 35 in the said plate 2, when the forked lever 3i, which is simultaneously lowered, engages with and rocks the pivoted trigger 29, which in turn through the mel (hum of the spring-pin 3U,

weighted detent-lever 10 into engagement with the shoulder 9 of the reciprocating bar 8,and so throws off the impression. After the platen 5 has passed the point at which the type-bed has actually commenced to "shorten its stroke the pivoted trigger 12S) is rocked back into its normal position, through themedium of the spring-pin 30, by the engaging forkcd lever 31 during its next upward movement, when the said weighted detent-lever 10 again assumes its disengaged position, and in this way the detcnt-levcr ll) is operated so as to throw oll' the impression automatically each time an envelop fails to 1 be fed onto the feed-plate 2.

What I claim as .my invention, and desire to secure by Letters Patent, is-

l. The combination with a feed-plate of a feeding device for printing-presses comprising a container-box, a curved delivery-finger to en age the envelops between their llaps and t eir bodies arranged to lift them from the container-box, and a bridge above the container-box to prevent more than one enl velop being deli ered at a time, the curved l linger operating to draw the cnvelops one at i a time from underneath the bridge as it lifts L them from their container-box.
