JA'ME'S A. 0414615 ATTORNEY PEGBOARD TYPEWRITER This invention relates to typewriters capable of typing on a flat surface, and more particularly to a typewriter for typing entries onto pegboard business and accounting forms.

Pegboard accounting systems have gained wide usage by doctors, dentists, attorneys and other professional offices as a means for maintaining a record of services performed, accounting for services and charges to individual patients and clients, and for recording payments received. These systems generally employ a number of interrelated accounting forms that are held in alignment on a pegboard so that a single entry is recorded on one or more of the several forms. The pegboards are typically comprised of a flat metal plate of a size sufficient to accommodate the largest of the forms, which serves as a writing base, and one or more lines of pegs protruding from the face of the plate. The accounting forms are provided with a plurality of holes which rather precisely correspond in size, shape and spacing with the pegs, so that when placed on the pegboard the forms are held in secure alignment, yet are readily removable from the pegboard. The pegs are often conveniently arranged in a line along the left hand edge of the pegboard. However, pegboards are available which employ multiple lines of pegs, such as lines of pegs along both the left hand and right hand edges of the board, or along a line intermediate the edges of the pegboard. Also, pegboards are available which have one line of pegs mounted on a rail that is slidably movable with respect to the pegboard base, so that the forms held on this rail can be moved with respect to the forms held on the stationary pegs.

While these pegboard business and accounting systems offer many advantages, heretofore it was required that entries on the pegboard forms be handwritten. Handwritten entries in business and accounting records are no longer acceptable in many circumstances, and particularly in bills and statements sent outside the office. Thus, there is need for a device for making typewritten entries onto pegboard business and accounting forms.

Accordingly, a principal object of this invention is to provide a typewriter for typing entries onto pegboard business and accounting forms.

Another object of the invention is to provide apparatus for supporting a pegboard adapted to hold pegboard business and accounting forms in a typing position adjacent a typewriter capable of typing directly onto the pegboard forms, including means for providing horizontal letter spacing and vertical line spacing.

Still another object-of this invention is to provide a typewriter for typing entries onto pegboard business and accounting forms including means for providing horizontal letter spacing and vertical line and half line spacing.

A further object of this invention is to provide a typewriter for typing entries onto pegboard business and accounting forms including means for providing predetermined horizontal spacing corresponding to standard columns on the pegboard forms.

The manner in which these and other objects and advantages of the invention are realized will be apparent from the specification and claims considered together with the accompanying drawing wherein like numerals refer to like parts throughout, and in which:

FIG. 1 is a front elevation view-of the pegboard typewriter of this invention;

FIG. 2 is a side elevation view of the apparatus;

FIG. 3 is an enlarged sectional view taken along the line 3-3 of FIG. 1;

FIG. 4 is a partial sectional view taken along the line 4-4 of FIG. 3;

FIG. 5 is an enlarged sectional view taken along the line 5-5 of FIG. 1;

FIG. 6 is a partial sectional view taken along the line 6-6 of FIG. 1;

FIG. 7 is a perspective view of the escapement and tabulator mechanisms; and

FIG. 8 is a partially cut away side elevation view of the typewriter showing the escapement and tabulator mechanisms.

Referring more specifically to FIGS. 1, 2 and 3 of the drawing, numeral 10 designates generally a frame which can comprise a substantially rectangular box formed by left side member 12 (relative to a position facing the front of the apparatus), right side member 14, top member 16 and back cover panel 18. Interior partition 22 extends substantially the length of frame 10 parallel to side members 12 and l4'and in a conveniently spaced relationship at the right side of frame 10. Members 14 and 22 are provided with slots 190 and 192, respectively (slot 192 being illustrated in FIG. 5), to accommodate line spacing lever 70 as will be hereinafter more fully described. The right hand section of frame 10 between side member 14 and interior partition 22 is covered by front cover panel 26. Thus, frame 10 defines a shallow box-like structure having a closed section along the right side and a larger, central open section. Frame 10 can be fabricated of metal, wood, or plastic, or combinations of these materials, and can be constructed by assembling the individual members, or by forming an integral structure by molding, pressing, or other convenient technique. However, whatever means of construction is employed, frame 10 must be of sufficient strength and rigidity to support the various operative components of the apparatus.

Frame 10 is supported at an angle inclined to the rear of the device by means of a suitable supporting structure, which can take the form of a pair of legs 30 pivotly attached to frame 10 by meansof a pair of hinges '32. The angle through whichlegs 30 can be pivoted is limited by chain 34 attached to each of legs 30 and to frame 10. In this manner, frame 10 is supported at a convenient fixed inclined angle so that the writing material being inscribed upon can be conveniently viewed by an operator positioned in front of the apparatus, yet legs 30 can be readily folded for transport and storage. However, it is to be recognized that any convenient means fur supporting frame 10 at a suitably inclined angle can be employed.

Pegboard 40 is slidably mounted in the central open section of frame 10 by means of a pair of parallel rails 42 located at each side thereof, and a mating pair of rails 44 attached to pegboard 40. Pegboard 40 is slidably supported between the rails 42 by bearing as.- semblies 46 that travel in raceways formed by the mating rails 42 and 44. Pegboard 40 is a conventional pegboard assembly comprised of a flat, generally rectangular plate having a plurality of pegs 48 arranged in a line along its left edge. Pegs 48 can be formed integrally with the plate, or can be individually attached to the plate, or can be attached to a separate rail, such as the rail 50. Alternatively, various other embodiments of peg assemblies can be employed, exemplary of which are pegboards having a line of pegs along the right edge of the pegboard, or at an intermediate position in the central portion of the pegboard, or wherein at least one line of pegs is mounted on a rail that is slidably movable with respect to the pegboard, such as pegs 52 attached to rail 54 that is slidably mounted at the right side of pegboard 40. The weight of pegboard 40 is counterbalanced by spring loaded automatic tape reel 56 which is mounted on the interior of back cover panel 18, or alternatively on the interior of top member 16, the spring loaded tape 58 being attached to pegboard 40.

Typewriter 60 is supported in a substantially horizontal position at the front of frame by means of typewriter support base 62 which is secured to frame 10 by a pair of brackets 64 and threaded braces 66. Typewriter 60 is adapted for transverse movement on support member 62 to provide letter spacing, as will be hereinafter more fully described, and is positioned with respect to pegboard 40 so that the type face strikes the writing material held on pegboard 40 so as to render an impression thereon. Thus, typewriter 60 and pegboard 40 are mounted so that pegboard 40 is adjacent to and immediately rearward of typewriter 60, and pegboard 40 is inclined away from typewriter 60. A translucent plastic shield 180 is attached to the rear of typewriter 60 to assist in maintaining the writing materials in a writing position on pegboard 40.

Pegboard 40 is moved upwardly and downwardly along the angle of inclination of frame 10 to any one of a plurality of positions by means of line spacing lever 70. As particularly illustrated in FIGS. 3 and 4, lever 70 is pivotly attached to pegboard 40 by means of bracket 72, mounted on the rear surface of pegboard 40, and by -pin 74. The pin and bracket assembly is constructed so that line spacing lever 70 has substantially, no lateral movement, and can move only about the axis of pin 74. Line indicator 76 is attached to line spacing lever 70 andprotrudes outwardly in front of front cover plate 26 through the elongated slot 78 therein. Scale 80 is inscribed adjacent to slot 78 to indicate the line that is then aligned with typewriter 60 for typing. It is apparent that if the lines of pegboard 40 are numbered downwardly, scale 80 must be inscribed in reverse order since the top line-will be inscribed upon when pegboard 40 is inits lowest position, and the bottom line when pegboard 40 is in its highest position.

Pegboard 40 is maintained in any one of a plurality of positions corresponding to a particular line of typing by latching line spacing lever 70 into line spacing rack 82.

As particularly illustrated in FIGS. 3 and 5, line spacing rack 82 is a flat, elongate member having a serrated edge, and is fixedly attached on the inside of interior member 22, i.e., on the side adjacent the central section of frame 10, so that the serrations or teeth 84 project outwardly into slotted opening 192 in the member 22. Line spacing rack 82 is positioned with respect to the location of pegs 48 on pegboard 40 so that the spaces between serrations 84 each correspond to a line of typing. Line spacing lever 70 is biased forwardly by spring 86 so that lever 70 is firmly held in engagement in the space between two adjacent serrations 84, thus maintaining pegboard 40 in a fixed position so that typing can be accomplished along a single line. Pegboard 40 is raised or lowered to shift to another selected line of typing by applying sufficient force against line spacing lever to overcome the spring bias and pivot lever 70 rearwardly about the axis of pin 74; Line spacing lever 70 need move only sufficiently toclear teeth 84 on line spacing rack 82. With line spacing lever 70 moved to an unlocked positiompegboard 40 can be moved upwardly or downwardly to any selected line space position by moving lever 70 in an upward or a downward direction. Pegboard 40 is locked in position by releasing the force exerted on line spacing lever 70 and lever 70 is biased forwardly into locking position by spring 86.

Corrections on pegboard accounting and business forms are conventionally made by striking out the er roneous matter and inserting the correction between the line containing the entry and the line next above it. The pegboard typewriter 60 of this invention allows corrections to be made by this technique. To make a correction, the erroneous matter is struck out and correction key 90 depressed which permits shifting of pegboard 40 downwardly one-half line so that the corrected matter can be inserted one-half line above the line previously being typed upon. As particularly illustrated in FIGS. 3 and 5, correction key 90 is pivotally attached to correction rack 92 by pin 94. Correction rack 92 is a flat, elongated member having a serrated edge and is mounted on the outside of interior partition 22, i.e., on the side opposite that to which line spacing rack 82 is fixedly attached, by means of a pair of pins 96 projecting through slots 98 in rack 92. Correction rack 92 is biased in a forward position by means of a pair of springs 100 attached to rack 92 and to interior partition 22. In its forward position the serrations or teeth 102 along the edge of rack 92 do not project into the slot area, and positioning of line space lever 70 is accomplished by fixed rack 82. However, when correction key 90 is depressed, the biasing force is overcome and correction rack 92 is moved rearwardly a sufficient distance that serrations 102 project outwardly past the serrations 84 in fixed line spacing rack 82, and rack 92 is locked in this position. With correction rack 92 in this operative position, line spacing lever 70 can be moved to any selected position between any two adjacent serrations 102 to provide half-line spacing of pegboard 40. Correction key 90 is biased upwardly by spring 104, and as correction key 90 is depressed a notched section 194 thereof engages latch 106 to lock correction rack 92 in its operative position. A downward force applied to correction key 90 overcomes the bias of spring 104 and disengages key 90 from latch 106, permitting the bias of springs 100 to return correction rack 92 to its inoperative position.

Typewriter. 60 is slidably mounted on typewriter support base 62 so that typewriter 60 can be moved transversely to the left and right of frame 10 to provide letter spacing. FIGS. 1, 2, 6 and 8 illustrate the mounting of typewriter 60 on typewriter support base 62 to provide transverse movement of typewriter 60 and to permit adjustment of typewriter 60 with respect to pegboard 40. Base plate 110 and carriage rail 112 are elongated members adjustably mounted on the upper surface of typewriter support base 62. Carriage rail 112 is grooved along each edge to receive carriage rail assembly 114 which is fixedly attached to the underside of typewriter 60. Thus, carriage rail 112 is fixedly attached to typewriter support base 162 and carriage rail assembly 114 is fixedly attached to the typewriter 'frame, lateral movement of typewriter 60 being provided by bearings 116 operating in the grooves along the edges of carriage rail 112. In this manner, typewriter 60 is firmly attached to support base 62, yet is freely movable in a transverse direction. Additional support can be optionally provided by wheel 170 supported from the typewriter frame by bracket 172.

Base plate 110 and carriage rail 112 are adjustably attached to typewriter support base 62 by bolts 120 that pass through relatively large diameter apertures 122 in typewriter support base 62, and through smaller aligned apertures 196 and 198, respectively in base plate 110 and carriage rail 112. With bolts 120 tightened, carriage rail 112 and base plate 110 are held in fixed position with respect to typewriter support base 62. The proximity of typewriter 60 to pegboard 40 is al-' tered by adjustment screws 124 which threadably engage block 126, which in turn is fixedly attached tothe underside of support base 62. The typewriter position is adjusted by loosening bolts 120 and turning adjustment screws 124 in the proper direction to move adjustment block 128, bolts 120, base plate 110 and carriage rail 112 either closer to, or further' from pegboard 40. In this manner typewriter 60 is positioned so that the letters strike the surface of pegboard 40. Also, the angle between typewriter support base 62 and frame is adjusted by threaded braces 66 to provide on feet adjustment, i.e., adjustment of the angle at which the type face strikes the typing surface. Thus, by proper adjustment of the distance of typewriter 60 from pegboard 40 and its angle with respect thereto, the type face is made to strike squarely on the typing surface.

The lateral movement of typewriter 60 with respect to pegboard 40 is controlled by the escapement and tabulator mechanisms. During normal typing, the

escapement mechanism is in an operative position and typewriter 60 is movedone space to the right by striking a selected letter or spacing key, is moved one space to the left by depressing the back space key, or can be shifted to the'left or right freelyby depressing the carriage release key. Depressing the tab key moves the escapement mechanism to an inoperative position and the tabulation mechanism to an operative position, thereby allowing typewriter 60:to shift to the right to the next tab stop. The tab stops in the illustrated embodiment are permanently set to coincide with columns on the accounting and business forms placed on pegboard 40, however, adjustable tab stops can be employed. Thus, depression of the tab key allows typewriter 60 to shift to the right to the next column for typing thereon.

As illustrated in FIGS. 7 and 8, the escapement and tabulator mechanisms are comprised of escapement rack 130 and tabulator rack 132 mounted on either side of and parallel to carriage rail 112. Escapement rack 130 is provided with a plurality of closely spaced serrations 134 along its inner edge to provide letter spacing, and tabulator rack 132 is provided with more widely spaced serrations 136 to provide tabular spacing correspond to columns on the pegboard forms. Escapement rack is pivotally attached to carriage end plates 138 by pins 140, and carriage end plates 138 are mounted at each end of base plate 110. Slots 174 are provided in typewriter support base 62 at either end of carriage rail 112 to accommodate the escapement and tabulator control mechanisms, which project downwardly below the surface of typewriter support base 62. Tabulator rack 132 is pivotally attached to carriage end plates 138 by pins 144, and is connected at both ends with escapement rack 130 by connecting links 146. Tabulator rack 132 is in turn connected to tabulator channel bail by connecting links 152.

The shift key 154 of typewriter 60 is converted to a tab key by connecting shift key arm 156 to tabulator channel bail 150 through linkage 158 terminating in roller 160 which movably operates in the channel of tabulator channel bail 150. Thispermits movement of typewriter 60 independently of the escapement and tabulator mechanism yet maintains tab key 154 in operative connection to these mechanisms. Channel bail 150 extends the length of carriage rail 112 so that roller 160 is in operative contact with channel bail 150 throughout the travel of typewriter 60. Also, the escapement and tabulator mechanisms are moved with carriage rail 112 when adjusting the proximity of typewriter 60 to pegboard 40, as hereinabove described. When tab key 154 is depressed, arm 156 is caused to pivot about pin 164 overcoming the bias of spring 162 which maintains tab key 154 in a normally non-depressed position. As arm 156 pivots about pin 164, tabulator channel bail 150 is lifted by means of linkage 158 causing tabulator rack 132 to pivot about pins 144, thereby moving serrated edge 136 of rack 132 forward into operative position. Simultaneously therewith, escapement rack 130, by its connection tabulator rack 132 through connecting links 146, is caused to pivot about pins 140 moving escapement rack 130 forward out of engagement with the typewriter spacing mechanism. Accordingly, typewriter 60 moves to the rightto the next tabulator stop 136. I

The overall size of frame 10 required to house the assembly can be reduced if pegboard 40 is permitted to extend beyond the top and the bottom of frame 10 in its most extreme positions. Accordingly, it is preferred that a slot, not shown, be provided in top member 16 to permit pegboard 40 to extend above frame 10in its most extreme upward position. Similarly, it is preferred that the bottom be left open to permit pegboard 4,0 to extend downwardly below frame 10in its most extreme downward position. Alternatively, the bottom can be covered with a suitable cover plate having a slot to accommodate the downward travel of pegboard 40.

A typical application of the pegboard typewriter of this invention is illustrated by its use in the pegboard accounting system employed by many doctors. First a large day sheet or journal is placed on pegboard 40. Next, a number of transaction receipts are placed on pegboard 40 so that they overly the day sheet, each transaction receipt corresponding with a different line on the day sheet. The transaction receipts are commonly supplied in shingled sets of about five receipts and are typically wax spotted on the reverse side along a top line so that entries made on this line are reproduced on the form next below the transaction receipt. When a patient is received, their name and other pertinent information is typed on the top line of one of the transaction receipts, and is thus also reproduced on the day sheet. The transaction receipts commonly have a perforated stub portion that can be torn off and attached to the medical file that accompanies the patient into the treatment room. At the conclusion of the treatment, this stub portion can then be returned to the receptionist. The patients individual ledger card is then inserted beneath the transaction receipt and positioned so that the entry will be made in the proper place on the ledger cards. These ledger cards are usually NCR treated on their reverse side so that entries are reproduced on the sheet next below the ledger card. With the ledger card properly positioned,

- the treatment and the amount of the fee and charges are typed onto the transaction receipt and simultaneously entered on the patients individual ledger card and on the day sheet. Similarly, payments are recorded on a transaction receipt, on the ledger card, and on the day sheet. Also, a bank deposit receipt can be incorporated into the pegboard accounting system so that the bank deposit receipt is prepared simultaneously with the entry concerning each patient. The description of the foregoing accounting system is exemplary of the forms and procedures that can be utilized, and while the particular forms and business system employed does not form a part of this invention, the system is flexible and many changes and modifications can be made.

A conventional typewriter can be converted for use with the pegboard apparatus of this invention by removing the carriage and the rear portion of the frame and cover panels. The carriage can be attached to the bottom of the typewriter to serve as carriage rail assembly 114. Sinceno carriage shift is provided, only single case type can be employed. Single case gothic type is preferred because of the similarity of type style. Also, where a conventional typewriter is adapted to this service, it is usually necessary to resolder the type faces so that the type face strikes the typing surface at the proper angle.

While various embodiments of the invention have been described, it will be obvious to those skilled in the art that it is not so limited, but is susceptible of various changes and modifications, which are considered ,within the spirit and scope of the invention as defined by the attached claims.
