O. HIDALGO DUPLICATOR Filed July 21. 1921 \xm iil f wuw imur;
Patented May it, 1924-.
OSCAR HIDA'LGO', OF NEW YORK, N. Y.
DUPLIGATOR.
Application filed July 21,
To all whom it may concern Be it known that I, OSCAR HIDALGO, a citizen of the Republic of Chile, and a resident of New York, county and State of New York, have invented certain new and useful Improvements in Duplicators, of which the following is a specification.
The present invention relates to duplicators of the class described and shown in the co-pending application filed May 28th, 1921, Serial No. 473,348, and more particularly to accessories thereof.
A duplicator of this class has a curved presser plate carryingon its outer face an ink pad and stencil sheet. The ink pad is attached in position by rigid members or rods of the inkpad engaging sockets provided at the ends of the presser plate. The
. In the accompanying drawing w of the operatingv base; Fig. 2
. will be hereinafter more fully described and printing operation is performed by swinging the curved duplicator from one end to the other over the face of the sheet like the well known press blotters, whereby the mat ter written or printed on the stencil sheet is impressed on the sheet.
The principal object of this invention is to provide an operating base with means to hold the sheets of a pile in alinement and equip the base with means whereby the duplicator may for each operation be quickly properly" positioned over the pile soas to produce uniform neat and clean copies.
\ Another object is to make said means adjustable to conform with various. sizes of sheets and various arrangements of the copied matter on the sheets. 9
With these and other objects in view my invention consists in the novel construction, arrangementv and combination of parts as defined inthe appendedclaims.
Fig. 1 a top planvie is an enlarged section on line22 of .Fig. 1; Fig. 3 is a topplan View of a modlfied v I construction ofthebase; F 1g. 4.91s an en- Iarged section online .4l-i of Fig. 3; Fig. 5 is an enlarged section online 5..5 of,F1g.'3
yand Fig. 6 is an enlargedsection on line 6 -6 of Fig. 3 Inpthe ,wood or: other suitable material substan I larger both .in
.tially. of rectangular shape designed to be completely I drawing. .10 denotes... a board of length. and ,Width than the duplicator and serving as an operatingon printing base- The board 10;.is equipped,
1921. Serial N0. 486,540.
with members 12, 12 projecting from its upper face and adapted to serve as marginal stops or guides for the sheets adapted to be arranged in a pile thereon, whereby the sheets will be held in proper alinenient with one another during the printing operation. The members 12, of which there may be one or more, are arranged near the end ofthe board, which relative to the direction of operation is the front end, and one or more of the members 12 are located near one side of the board. These members are arranged outside of the space adapted to be occupied by the stack of sheets and may be in form of bolts or the like. The printing being effected by rolling or swinging the duplicator from oneend to the other, it is necessary, in order to prevent the duplicator from striking the front member 12 when its front end islowered and overlaps the front ends of the sheets, to make said member 12 yielding in -vertical direction. To this end the bolt 12 is movably borne in a bore 10 extending throughout the thickness of the board and which is somewhat enlarged at its bottom to form a socket for a member 13 to which one end of a spring 14 is attached. The bolt 12 at its inner end may be formed with. a flange12eadapted to slidably bear on the walls of the enlarged portion of the bore flange 12 and that of'the member 13 is sufficiently large to permit the bolt 12 to be depressed so that its outer end will be flush wither belowthe upper face of the board. I
' In orderto facilitate the positioning of theduplicator prior to the printing operation sothat the matter. to be'copied on the .sheetswill .runvstraight and appear on the sheets at the desired place, I provide the following means The cylindrically curved presser plate of the, duplicator a which is indicated in dotted .lines in Fig. 2, is provided with lateral projections b which in thew-pending applicationrabove referred to are formed by the ends of "rigidmmembersuor, .rods of-the. ink
pad, but vwhich,ofcOurse, maybe independent, of the ink pad and fixedto any suitable place ofthe longitudinal walls of the presser plate. -1
l Extending longitudinally zfnearflthe side edges of the board andoutside of. the space to occupied by. the 'sheetsare grooves 10 v1n the sockets 17 which on top are covered by metal strips countersunk in the board as at 10 and fixed to the board by screws 16 or the like. These strips are formed with longitudinal slots 15 constituting guides for nlembers 17. These members are in form of elbow pieces, the horizontal parts of which slidably bear on the strips 15 and the vertical parts of which are. directed towards one another and are formed with vertical notches 17. The horizontal piece of each member is provided with a bore 17 through which extends a bolt 18 projecting through the slot 15' into the groove 10 and formed on its inner end with a head 18. On the outer screw threaded ends of the bolts works thumb nuts 19 serving for the tightening of the members 17 in adjusted position. The notches 17 of the elbow pieces 17 serve as sockets for the lateral projections b of the duplicator so that the latter upon its engagement with the said corner pieces may be properly positioned prior to the printing operation. According to the length of the sheets used or the arrangement of the printing matter on the sheets the two corner pieces can be adjusted longitudinally to be in juxtaposition and at the desired distance relative to the sheets. For facilitating cor rect adjustment of the two corner pieces, to prevent printing on a bias and permit the arrangement of the matter copied within the desired space, scales 20 may be provided alongside the strips 15 as shown in Fig. 1.
In the present example the projections 7) are assumed to be arranged at one end of the duplicator. In such case the projections will engage the notches 17 of the elbow pieces 17 only at the beginning of the printing operation, that is to say, at the moment the duplicator is placed with its rear end onto the sheet while its forward end is raised. When the duplicator is rolled over the face of the sheet the rear or lowered end thereof will rise and the projections I) will be lifted from the notches 17 When,
however, the projections are arranged cen-' trally of the duplicator the pieces 17 so adjusted that the may be projections will remain during each printing period.
By the provision of the guide members 17'for the duplicator the printing of numerous copies in the shortest possible time is rendered possible, and uniform clean and neat copies can be produced.
In order to enable the use of sheets of various sizes the guides 12and 12' may be made adjustable longitudinally and transversely respectively. Such construction is shown in the modifications of Figs. 3 and 5. Here the board 21 is provided at one end,preferably centrally, with a longitudinal groove 21, the bottom of which is formed by a removable" plate 22 on which is slidably mounted a disk or plate 23 having a projecting pin 2%. The guide bolt 25 that corresponds to bolt 12 of the constructlon shown in Fig. 1 is formed with a longitudinal central groove 25 whereby the bolt 25 is movably mounted on the pin 2 1. A spring 26 attached to the disk or plate with one end and hearing at its other end against the flange 25 of the bolt 25 tends to hold the latter projected outwardly from the groove 21. This bolt 25 is thus yielding vertically and also capable of adjustment longitudinally. The board 21 is also provided with transversely extending parallel grooves 27 preferably of dove-tailed cross section, as indicated by dotted lines in Fig. 3, to slidably bear correspondingly shaped strips 28 of metal or wood. Said strips are at their outer faces flush with the board and carry at opposite ends each a bolt 29 which projects upwardly and serves as stop or guide for the sheets. By moving said strips or bars in opposite directions, the bolts 29 may be brought closer or farther away relative to one another according to the size of sheets used.
The bolts 29 may also be made yielding vertically like the bolt 25 or 12, to prevent the duplicator from striking them when the sheets used are narrower than the duplicator. To this end the pins 29 are movably borne in bores 28 of the strip 28 and are supported on suitable springs 30 fined to the inner face of each strip.
The elbow pieces 31 for the engagement of the duplicator as shown in this modifica tion may be attached to blocks 32 of time tailed cross section slidably borne in longitudinal correspondingly shaped grooves 33 provided in the board 21. The tightening of the blocks 32 in adjusted position may be effected by set screws 34 (see Figs. 3 and 6).
What I claim is 1. An operating board for a duplicator having lateral projections. said board having longitudinal marginal guide grooves, members adjustably mounted in said guide grooves and constituting sockets for said lateral projections and means for tightening said members in adjusted position.
2. An operating board for a duplicator having lateral projections. said board having longitudinal marginal guide grooves and members adjustably borne in said grooves and formed with projecting notched portions serving as sockets to engage said projections of the duplicator and means for tightening, said members in adjusted position.
3. An operating board for a duplicator 1 i an jecting notched portions adapted to form sockets to engage said projections and means for tightening said members to said plates in adjusted position.
An operating board for duplioators, said board having a longitudinally adjust able resilient member and transversely ex tending slides having vertical projections at opposite ends of the slides, said member and projections forming marginal stops for the 10 sheets.
