To aZZ whom t .may concern: l Be it known that I, ERNns'I"` tI. Brasseur, a citizen of the United States, residing 1n .the city of Chicago, county ofiCoolr, and

lin` a mannervthat does not permit excessive "1 feeding of the ink 'during the duplicating p operations of the machine.

. rated diaphragm to .assist in distributingthe'ink over the diaphragm inA an'entirely new mannergandto thereby obtain a more' A furtherpbjectjof. the invention is'to1 provide a simple form of 'constructional' means `to be quicklyeaiixed in position in close proximity or in contact withthe perfoleven intensityzof printing during the duplicating operations. Another objectl ofl this invention is to delsign the constructional` parts of theapparatus so they may be quickly manufactured at minimum costsandmay be readily as-"' semble in the machine.

Reference is hereby, made to a copending application by the same 'inventor executed at even date herewith and entitled Duplicat' ing machines. .The referred to application includes additional features relating to the novel inking means.

tion yis illustrated in ings wherein; f

in section vof portions of the diaphragm and the" grid" illustrating the joining edges f of two of the grid sections. *Referring now7 to these drawings a diaphragm 1 of the usual StenOil-Carrymgduplicating machine is shown in portion and is provided with the usual perfo-rations 2 which permit ink placed on said Idiaphragm to pass toa suitable ink pad and from there to astencil, all of which construction is Well known in the art. In this particular form of diaphragm it is desired to have the ends of the diaphragm upturned or bent inwardly to form abutments 8' and 4. These abutments are provided with suitable series of openings 5 and 6 which permit ink flowingl from the diaphragm to pass to another .portion of lthe 'duplicating apparatus more fully described infthe other application above referred to.

' In describing in .detail the means employed for assisting in distributing ink over the perforated diaphragm and for maintaining a small free supply "of ink in contact with said diaphragm, it has been found desirable to mount such a means in close association with said diaphragm .as will guide the inkphragm. tWhen'- desired a screen of large 'meshprope'rly positioned in relation to the diaphragm maybe employed in accomplish- 'ing thisfpurpo'se. It is to be understoodI that the frame or grid may be placed in contact withthe diaphragm or slightly above it. either case the grid is considered to be in close association with the diaphragm.

'In setting forth and describing the most simpleoo-nstruction to attain this proper distribution, it has been 'found advisable from the manufacture and assembly standpoints to form the grid in a series of sections here illustrated vas end sections and 8 and an intermediate section Y10.y It is to beA diaphragm for accomplishing v Such a framework or grid 1s loo understood thatthese sections form a complete grid and if desired may be, constructed inthe form of a single unit. This preiA l ferred form provides a series of partitions 110.'

small enclosures or. areas partitions thereby -maintaining a small supply of ink that is free on said diaphragm but yet not in such relation to the diaphragm as to force ink therethrough.

During the operation of the duplicating machine, the diaphragm 1 and the

grid sections

7, 8, and 10 will be rotated, but the grids will remain non-movable in respect to the diaphragm.' During this rotation of the drumit will'be readily perceived that a small proportion of ink will endeavor to flow out of the enclosures and the grid has been constructed to permit the ink to flow from one area or enclosure to another.. The preferred constructiongfor accomplishing and permitting the ink to flow out of one area to another and still retain some ink within each area is to provide suitable notches 14 in the longitudinal partitions and to preferably position the cross parti/- tions above the diaphragm as illustrated in Fig. 1. It is to be understood that notches may be provided in thebottom edges of the cross partition 12 if desired or other constructions may be employed.

Any suitable means may be used to maintain the grid in normal position in respect to the perforated diaphragm. The particular construction which is desired for this purpose includes the positioning of y suitable anges 15 near the edges of the perforated diaphragm as illustrated in the drawings. The grid sections are constructed so as to be positioned between these flanges, and in assembling the sections of the grids it will I be noted that grid 7 is placed in contact with abutment 3` and that section 8 is placed in contact with abutments 4. Each of these sections is provided with cross partitions 16 and 17v respectively which are positioned at angles to the perforated diaphragm. The intermediate or middle section 10 ofthe grid has its two

end partitions

18 and 20 also formed at angles to properly engage the partitions 16 and 17 of sections 7 and 8. With such construction a suitable fastening means engaging only the middle section 10 becomes necessary. This Vwill be readily appreciated where it is noted that as section 10 is assembled in position sections 7 and -8 are forced against abutments 3 and 4 respectively by reason of the angle positions of

partitions

16, 17, 18 and 20. The means for fastening the middle section inpositoy be quickly tion comprises a suitable screw stud 21 as noted in Fig. 2 and it cooperates with flange 15. It is to be understood that other simple and suitable fastening means nay be employed if desired.

It will be seen from the foregoing description that the ink ,distributing means mounted in 'close association with the perforated diaphragm is simple of construction and permits the manufacture to be completed at reduced costs, and it is arranged assembled in non-movable pos1t1on 1n desired relationy to thev diaphragm.- 'When the grid or frame is in normal position it will `be noted that the ink received by the diaphragm will be automatically distributed over the diaphragm in a substantially uniform manner and by reason of nthe grid construction a small free supply of ink will be maintained in contact with the diaphragm thereby obtaining \substantially uniform duplicating results from the operation of the machine.

It will be understood that while there is here described in detail a particular embodiment of the invention for purposes of full disclosures, which are specifically clainied for a special advantage,` many changes and modifications' may be made in the particular construction and arrangement of parts without departing from the broad scope of the invention which is outlined in the subjoined claims.
