` 15 Claims.
"This invention pertains to a proof-reading .de-
vice for comparing typewritten matter but particularly to means for permitting the typed or otherwise inscribed matter to b'e matched.
Heretofore, in order to check the accuracy of typewritten or any kind of line for linel worky it has been necessary for one person to read back `from the original to a second person. Experience has proven, that after a comparatively short pee grod of time, the tendency is lfor one or both to' become drowsy and careless, thereby increasing the margin of error.
This invention contemplatcsnot only the elimination of the second 'persox'i` but reduces the num= ber of mistakes caused by earlier methods and in addition, permits the work to be completed in less time consumed by two people, and as a result puts the responsibility for accuracy upon the single individu-al performing the work.
While the present invention is primarily directed to comparison or matching of typewritten matter, it is obvious that many kinds of Stat-is tical data such as monthly insurance ledgers and payroll sheets of varying sizes may be expeditiously checlnedvand compared by the present apV paratus.
It is ari olojec'tofA my invention to enable type written matter to be matched or compared bya single operator.
Another object is to provide means for progressively disposing' one sheet of typed matter, line for line, in close proximity `with a second sheet of similar typed matter'. n
A further object is' to provideV means -for ad, justment for purposes of alignment ci one sheet with another.
A still further objectis to provide al receptacle for a pIural-ityof sheets of paper to be compared so that the top sheet will always be in the desired plane'.
Still another object is to provide" means for isolating the lines on the two sheets of Printed matter that are being immediately matched.
An addition-al object is to provide means for illuminating the desired lines ofthe' two sheets that are being matched.
Another and still fur-'ther object is to provide means for easy attachment and removal ofv the sheets' of printedlmatter.
Ar further additional object is to provide mea-ns for mechanically advancing a sheet of'type'd Inatter, line for line", in close proximity withY another sheet of typed matter fortl'ie purpose of match-- ing or comparison. f
Still another additional object is' to provide 2 means for selectively advancing asheet of typed matter one or more spaces for purpose of matchingr or comparison with a second sheet of typed matter.
Various other objectsl and advantages will be apparent from the following description of the accompanying drawings, which form a part of this disclosure and which illustrates a preferred forni of embodiment of the invention.
They manner ofaccomplishing the foregoing objects?, as well as further objects and advantages,- will be made manifest in the following description, together with the accompanying drawings, in which Fig. I is a plan view ofthe manually operated device comprisin-ga preferred embodiment of my invention.
Fig. 2 is a sectional vView taken on the line 2-2 of Fig. 1.

Fig; 1311s a diagrammatic view of the electrical circuit used in Figs. 11 and v12eP Fig. 1,4V is a' reduced plan View similar to Fig. l of another modification of the invention showing a construction designed to facilitate the comparison of larger sheets oi Statistical matter of vary-ing Widths.
Fig. 15 is an end View similar to Fig. 5 of the modification shown in Figure 14.
In the drawings, wherein like reference characters denotev like parts, the main support is indi# cated by the reference numeral l0. 4The central portion .i2isi cut out to accommodate a paper receptacle i4'. This receptacle is provided with side 'aiges to maintain a plurality of sheets of paper in stacked relation'. Interpc'sed between these 'sheets of paper I8 and the bottom of the receptacle is a plate 20. Springs 22 are secured to the plate 2% and the bottom of the receptacle I4 to urge the top sheet of paper in the desired plane. A hinged flap 24 at the bottom of the receptacle can be utilized to enable easy insertion and removal of the papers from the receptacle. It is to be noticed that the height of the opening I2 is greater than the length of the receptacle there: :by providing a space vI3 at the top and/ or Vbottom so as to permit vertical movement of the receptacle within said opening. A lever or handle 26 is shown to enable the receptacle to be moved `vertically in the opening I2 for purpose of alignment which will be morefully explained later.
v portance. Any conventional means, as indicated Y Secured at the top of the device is a support clamping construction is shown, although it is apparent that any type of paper holding means may be employed. This securing means 36 Yis designed to engage the top edge 320i the sheet of paper 3121 and has a length at least thatrof the width of the paper. Y
In Figs. 4, 5 and 6, I have indicated mechanical means for'the operation of the device. YGrooves 5G and 52 are provided to receive the supports 54 and 5b, allowing of vertical movement along the I ering or black-out substance ||9 to enclose this sides of the device. A tape, band orxany other in any well known manner as at 69. This memflexible member 58 is secured to the support 5S ber 53 isY also secured tothe rotary member '62 located in an opening 63 at thev bottom of the device and to a similarly rotatable device 64 con-.-
trolled by a spring 65. `The rotarymember- E2 Iis l' mounted on a shaftSS Which'has a bearing v68 mounted on the opposite side. The rotary meinber ed is similarly mounted on a shaft 'Ill positioned in an'opening 61,' having a bearing 'I2 mounted on the opposite side of the device.
Y Keyed at 69 to the shaft 66 on one side of the main support IU is a ratchet Wheel 14. Pivotally I mounted on a shaft I6 is an operating member 'I8 having a lever 8E?. A pawl 82, having a'cam stop B3 is secured to shaft 16, but lying inthe same plane as the ratchet wheel 14 and 'adapted to have r cooperative engagement therewith and held in engagement bythe Vspring 84. movement Vofthe. opposed arm 86 of the pawl 82 i-s had by `means of a stop 8,8 positioned in its path. Adjustment 'oi'.this limitation is accomplished by the positioningof the stop plug 88 in any one of the openings 99, 92 or 94. YAnother pawl-QG is mounted at-98 on lthe operating mem- Limitd Y ber 'I8 and is continually urged into eng'agementjy by a spring |09. This pawl is prevented from dropping out ofposition by the stop IBI when the operating member I8 is lifted out 0f engagementv to returnthe member 40 to initial position. Ex-` cessive vertical movement ofthe member 'I8 is prevented by spring |32 secured toiiange |04 on amaa I' 7 i l member I8 and to a support |06 mounted on the side of the device. Operation of the above construction will be explained later, the associated structure otherwise being the same as described in Figs. 1, 2 and 3.
In Figs. '7 and 8, a modification shows means for accentuating the two lines that are to be immediately compared. A plate |08 is hinged at Il!) tothe member 4i] although 'it is conceivable that it could be attachedlto the support 38. An opening I 2 is provided so that, in effect, the other lines of type or'indicia are diminished in imat IIA may be used to enlarge the opening ||2 to permit more than one line of type to be viewed.
, Fig. 8 is an enlarged sectional View ofthe top I of the device to/more clearly indicate the relationship of the two sheets of paper. The top of the second sheet 34 is attached to the securing member 3u and then folded under the member ilbutabove the'rst sheet. TheY bottom of the second sheet then extends outwardlyfrom the top of the device made easy by the reduced portion 48.
.progressively come into view adjacent the desired lines of the rst sheet. For purpose of matching or comparison, it is an objective to have the desired lines of each sheet to lie as nearly as possible inthe same plane. Y
Figs. 11, l2 and 13 show a modification which per-mits of illumination of the lines to be viewed. The well known properties of YI Iucite readily lendY themselvesl to applicationdn the present invention. In the enlarged sectional view of Fig." 11, I have shown the paper engaging and advancing member 40".' madeofLucite and having a covmember with therexception ofthe opening ||2'.V It is apparent, when illuminating means, such as the incandescent lamp IIB is positioned within the longitudinal openinggll,Y only the ,desired lines of both sheets |8 and 34 will'be accentuated.
Diagrammatic views of the illuminating meansv I6 and Sliding contacts are shown in Figs. 12 and 13.' Y The sliding member 38gis-shown positionedV in the groove 36 and is provided with contact plates |28 while the groove '435' is provided with correspondence sizedlpaper. In order to accom- Y' modate the larger width paper, the length of the advancing member 40 has' also,l been increased,
although'the supports l38 andthe groove construction remain the same. i Y
The securing means 30 for papersis slida'blyA mounted V(in-shaft 33,' secured to supports 35' at the outer edges'atithe top surface ofthe machine. The paper'securing meansVV 30 may be rpositioned and'held'` in placebyrja f 1 thftop edge of the winged nut'l orJ other securing means 3|, which construction per-mits` of slidabl'e' longitudinal movement" along"A shaft 33to`a1ig'n thev inscribed matter orA indicia d on the-paper 3|| he1d in position" by member' 3l wit-hthe selected column of inscribed m'atte'r or indicia af, 5; orc, on-tliemas ter sheet lii'n receptacle |14. y
