Specification of Letters Patent. I
' Patented Mar. 5, 1912.
Application filed September 22, 1909. Serial No. 518,989.
To all whom it may concern:
Be it known that I, JOHN J. FLANIGAN, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Copying-Machines, of which the following is a specification.
This invention relates to the art of multiple copying machines, or hectographs, as they are sometimes called, and has reference more particularly to a new and improved device including a roller platen forsimpressing the original and copy sheets upon the gelatinized duplicating band orother surface which receives the imprint of the record from the original sheet and transfers it to the copy sheets.
My invention has beendesigned primarily as a simplified improvement upon the roller platen disclosed in Letters Patent Number 965,887, granted to me on the 2nd day of August, 1910, on av multiple copyingv machine; but it will-be readily understood'that it is capable of'application to and use in .ZEwonnect-ion with any copying machine em- 'ploying a duplicating surface suitably sup.- ported to permit of. the passage of azplaten roller thereover.
' In the machine of my patent, above referred to, .the .roller platen is of such. a .nature that the impressed; portionHofnthe-paper sheet is rolled up thereon as .the platen advances over the band; whereas,..in my present device, .the impressed portion -of the paper sheet remains in flat contact with the band until the platen rollenmakes its return movement.
The device of my present invention com" prisesas to its chief structural features. a
4'3 suitable'frame mounted to move bodily on a slidewayof the duplicating machineand equipped with a pair of parallel rollsor their equivalents normally lying-in surface v contact with each other, between which the paper sheet containing the matter to be transferred to the duplicating band is passed, oneof said rolls beingfixedly journaled in the frame, and the other (which. is preferabl a rubber or rubber'surfaced roll) being ournaled in angularly movable arms whereby, through suitable connection to an operating handle, said last named roll may be retracted from the fixed roll toadmit the edge of the sheet between said rolls v and may then, in surface contact with said platen. frame and. releases said roll at the 1whereby to insuredhe introduction of the z iforward. edgeof. the sheet. to' the proper .amountor extent.
.athinjfiat stri .plicatingiban and formsa-rest or support for the upper blank edge of the sheet when fiXed roll, bemoved bodily toward and from return travel of the platen frame.
In connection with the rolls aforesaid, the device also includes an automatically acting lock which maintains the impression 0r platen roll in working position during both the forward and return travelof the completion of the return travel so as to permit-it: to be withdrawn from contact with the fixed roll for the subsequent insertion of a fresh sheet.
Stillanother feature. resides in the pro- .vision of. a,.pivoted, gage-barwhich coopcrates with theforwardfor advance edge of .the sheet to square the latter relatively to thevduplicating band, and also forms a stop Still anotherikfeature which-I, preferably employtoprevent sticking of the upper blank edgeof. the sheet to the duplicating band, consists of a shield; in the nature of or bar that overlies the dulthelatter is impressed upon the duplicating hand by-the. platen roll.
' Othenm-inor agents and accessories con tributingte the 'etficiency and .utility of the device. will be pointed out and explained .in
.the'following-.detail description of :its several parts and its manner of operation.
Inflthe accompanying drawings -I have illustrated one practical form in which the invention may be embodied, and referring .thereto,-
Figure 1 is a top plan view of the frame and duplicating'band of a copying machine, showing my improved roller platen mounted and. operating thereover, the platen frame being shown in working posit-ion. 110
Fig. 2 is asimilar view on an enlarged scale, showing only a portion of the machine frame and duplicating band, and showing the movable'parts of the device in the relative positions assumed when the impression roll has been raised out of contact with the duplicating band but not separated from the fixed roll. Fig. 3 is a bottom plan view of the platen with the parts in the positions assumed when the impression roll is in its lowermost or working position. Figs. 4 and 5 are cross-sectional views on the line 4-5 of Fig.- 2, looking in opposite directions, as' indicated by the arrows. Figs. 6 and 7 are cross-sectional views on the lines 66 and 7-7, respectively, of Fig. 1. Fig.
8 is a cross-sectional detail similar to Figs,
4 and 6, but showing the relative positions of the parts when the rolls are separated and with a sheet of paper introduced between them.
Referring to the drawings, 10 and 11 designate the opposite side-frame members of the copying machine, and '12 a horizontal 1 platform or table supported by and between said side-frame members and itself constituting a rest or support for the usual gelatin duplicating band. I have herein shown the machine as equipped with a pair of such duplicating bands 13 and 14, similar to theindependently operable duplicating bands disclosed inmy aforesaid patent. However, these parts of the apparatus are not material to the present invention, but are illustrated merely for the sake of making clearer the purpose and mode of operation of the latter.
Supported in brackets 15 secured to sideframe 11 is a rod 16 that constitutes a support and 'slideway for a carriage 17 secured to or integral with which is a substantially rectangular frame. member formed with parallel side walls 18 and 19 and parallel 7 end walls 20 and 21. Pivotally mounted within and between the end walls 20 and 21 of this rectangular frame are a pair of substantially'bail-shaped yokes or frames comprising parallel bars 22 and 23 which extend lengthwlse' of the containing frames and are formed at their ends with arms 24 and 25, respectively, extending at right angles thereto. The arms 24, carrying the bar 22,
are pivoted near their inner ends at 26 to the end walls 20 and 21, just inwardly of the frame wall 19, and the arms 25, carrying the bar 23, are pivoted near their outer ends at 27 just'inwardly of the frame wall 18 (-Fig.
I spectively, best shown in Fig. 7, which notches-constitute movable bearings for the reduced ends or'spindles 31 of the impression or platen roll 32, said spindles 31 in turn, constituting in effect a hinged connection between the arms 24 and 25, whereby when either pair of arms is rocked, the other is simultaneously rocked. The impression roll'32 is normally urged into surface contact with the fixed roll by torsion springs 33,- as best shown in Figs. 3 and 6, said springs bearing upon the reduced end por- 'tions of the roll.
Pivoted at 34 to the upper ends of the end walls 20 and 21 are a pair of arms 35. which support between them an angle-bar 36 that constitutes a gage-bar and stop to determine and limit the insertion of the sheet between the rolls 32 and 28, as well as to square the end of the sheet when so inserted. One of the arms 35 is connected at itsupper end above its pivot 34 by a tension spring 37 to 7 an arm 38 rigid with one of the roll-carrying arms 24 so that, when these latter are elevated, as shownin Fig. 8, to separate the rolls 28 and 32 for the insertion of the sheet, thegage-bar 36 is thereby swung into operative position opposite the space between said rolls to receive and square the forward edge of the paper sheet, in the manner clearly indicated in Fig. 8.
The upper portion of the side wall 18 of the frame is outwardly flared or inclined, as shown at 18*, thereby forming a suitable support for a. guide-chute 39 which directs the entrance and discharge of the paper sheet. This guide-chute has a fixed wall 39* on one side, and on the opposite side a movable wall 39 carried by a bent supporting clip 40 which embraces the adjacent end of the base-plate of the chute, being slidably supported and guided in keepers 41 on the under side of the latter, as plainly shown in the bottom plan view, Fig. 3.
As above stated, the roller platen of my inventionis designed to impress the paper sheet uponthe gelatin sheet during both its forward and return travel. To insure such action of the impression roller, I'provid a device in the nature of a'lock which, when the impression roller is lowered to working position, automatically. locks the same in said working position and maintains it of the frame, its lower end normally overlying the upper edge of one of the roll-carrying arms 24; whereby, when said arm is in lowered position, as shown in Figs. 6 and 7,
the lower end of the latch automatically swings over the upper edge of the arm 24, thus locking the impression roll 32in working position, as shown in Fig. 6. The latch 42 has a depending extension on its upper extension, coming in contact with a fixed stop 44 attached to the side-frame of the-machine, swings the latch out of locking engagement with the roller-supporting frame, and thus permits the latter to be. rocked so asto raise the impression roll to the intermediate or fully elevated positions for the discharge of the'used sheet and the introduction of a fresh sheet.-
The spindle 31 of the impression roll is, as best shown in the bottom plan view, Fig. 3, extended beyond the end wall. of the frame and terminates in a spirally grooved spool45 that engages a cord 46 (Fig. 1) se.
cured and extending between the brackets l5and having interposed therein a tension spring 47. The engagement of the spool with this cord, on the to and fro bodily travel of the platen, rotates the impression roll in an obvious manner, thus feeding the sheet between the rolls 28 and 32, as Well as pressing said sheet by a rolling. contact upon the gelatin sheet of thecopying machine.
Rigidly secured to and rising centrally from the bar 22 is an operating handle 48 equipped with'a' shield-49, by which handle the impression roll is manipulated, and the entire platen frame itself is actuated'to and fro above the gelatin-sheet.
I preferably employ in connection with the mechanism thus far described, a shield or guard-strip overlying the copying apron of the machine andadapted to support and shield the upper marginal portion of the.
sheet from contact with the sticky gelatinous copying band. This guard-strip, designated by 50,- is hinged at 51 to a bracket 52 that is clamped to the sides-frame member 10 in any suitable manner, as by a clamp-' screw Thebracket 52 has formed inter gral therewith a stop 44 hereinbeforereferred to .as cooperating with the downwardly turned extension 42 of" the latch 42; and, in order to gage the starting point of the roller platen at a uniform position relatively to the copying apron, I preferably provide a projecting lug 54 on the end wall 4 20 of the platen frame, which lug is adapted to register with and pass through a correspondingly shaped notch 55 in the stopmember 44 as the platen frame is swung downwardly into operative position above the shield 50. 4
In the operation of the device, the platen frame having been placed at its initial or starting position, as represented in Fig. 2, the handle 48 is swung back tothe limit of its movement, thus separating the rolls 28 and 32, in which movement the wall 19 of the frame is struck by the arm 38, thus constituting a stop for limiting the extent of cated in Fig. 8, being supported on the guide-chute 39 and squared by contact of its advance edge with the gage-bar 36. Upon releasing the backward pressure upon the handle, the springs 33 and 37 at once act to return the parts to the relative positions shown in Figs. 4 and 5, in which the rolls 28' and 32 grip the paper sheet between them. The platen frame is then lowered by the handle 48- to full working position by dropping the lug 54 through the notch 55, and the handle is then pressed forwardly to the position indicated in Fig. 1, which lowers the impression roll 32 to the working position indicated in Fig. 6, wherein it presses the paper sheet upon the surface of the duplicating band. The entire platen frame isthen pushed forwardly, the cord 46 and spool 45 imparting a rotary movement to the impression roll at just such a speed asis-necessary to cause it to roll without slipping overthe surface of the paper as the latter is thus fed down between the rolls 32 and 28. As the handle is swung forwardly, carrying the im ression roll down into working posi-tion, the latch 42 automatically drops into locking position over the upper edge of one of the arms 24, so that the parts are. thereby locked in the relative positions indicated in Fig. 6. The advance movement is continued until the space occupied by the printed matter on either the sheet orthe duplicating band has been passed over, and then the platen frame is returned, the impression roll being still held locked in lowered or working position. The platenframe is then returned, the impression roll, during the return travel, rotating, of course, in the opposite direction, so as to feed the sheet upwardly, butv at the same time'repeating the pressure upon the sheet and thereby the better insuring the transfer of-the record from the sheet to the apron or from the apron to the sheet, as the case may be, than where but a single impression is made. As the platen frame reaches approximately its initial or starting position, the depending. extension 42 of the latch 42 strikes the bracket 44, thereby releasing-the locking effect of the latch 42 upon the rower-carrying devices and permitting the handle 48 to be swung backwardly for the removal of the sheet and the introduction of a fresh sheet.
\ The shield 50 is not indispensable, but where employed prevents the upper edge of the sheet from sticking to the'apron, so that thelatter is readily withdrawn after the impression roll has been raised.
