The object of the invention is to provide improvements in drafting devices broadly, but more especially in a type which has been designed and is particularly adapted for use in making layouts 5 of floor and wall plans for the arrangement of furniture, furnishings, machine and general equipment units, and in fact for all purposes to which the device is adaptable.

In the following specification, it is to be understood that while the description relates more or less specically to kitchen layouts, involving the many possible arrangements of units designed for kitchen use, such description and the figures in the accompanying drawings are intended only to illustrate one of the many uses to which the improved drafting devices may be put.

More specically, another` object is to provide in such a device a compact carrying case in which the improved drafting board or base, the

series of novel stamps, the highly eiicient supporting and positioning mechanism for said stamps, the ink pad, etc., can be transported from piace to place, but which is at all times ready for immediate use.

A further object is to provide an improved design and construction of the individual stamps by which various units are indicated or represented, together with interchangeable means for readily adapting the device to unit stamps of diiferent sizes or widths, as well as means for accurately positioning the rubber or similar portions of such stamps upon their respective supporting elements.

With these and other objects in view, the invention comprises further details of construction and operation, which are hereinafter fully brought out in the following description, when read in conjunction with the accompanying drawings, in which Fig. 1 is a top plan view of a drafting board or base, together with parts and accessories which combine to form one embodiment of the invention; Fig. 2 is a bottom plan View of the stamp-holding element; Fig. 3 is a side elevation of the same; Fig. 4 is a fragmentary side elevation of one of the replaceable stamp-positioning bars, together with the supporting means for its opposite ends; Fig. 5 is a section of the same on the line 5-5 of Fig. 4; Fig. 5a is an end elevation of the parts shown in Figs. 2 and 3; Fig. 6 is a top plan View of one of the stamp supporting plates; Fig. 7 is a bottom plan view of the same with a stamp member amxed thereto; Fig. 8 is a top plan view of the jig for properly positioning a stamp with respect to its supporting plate whenV being secured thereto; Fig. 9 is a side elevation of the same with a fragmentary portion of a stamp and plate operatively positioned thereupon; Fig. 10 is an end elevation of the same; Fig. 11 is a section on the line II--II of Fig. 9; Fig. 12 represents an 5 impression of one of the stamp members, as for instance, upon a sheet of layout paper; Fig. 13 represents a series of such impressions to jointly represent a side of a kitchen or similar room; Fig. 14 represents the consecutive impressions of 10 a series of stamp members, to indicate a plan of the available working surface provided by the first six units of the layout shown in Fig. 12; Fig. 15 is a plan View of a modification, compris-V ing a combination of the functions of the guide 15 rod and the gauge o-r space bar shown in Figs. 1 to 5; Fig. 1G is an enlarged fragmentary sectional view on the line IB-IB of Fig. 15; Fig. 17 is a similar section but showing the relatively movable guide rod and radial arm in an inter- 20 mediate position between two operating positions; Fig. 18 is a side elevation of the radial arm and a modied form of stamp supporting plate partly in section; and Fig. 19 is a bottom plan View of the modified form of plate and 25 attached stamp.

Referring to the drawings, the drafting board or base I may be surrounded by a shallow ledge 2 and, if desired, may also be provided with a cover (not shown), adapted to span, enclose and 30 thereby protect both the surface of said board and the instruments and accessories mounted thereon.

Considering the board when positioned, as shown in Fig. 1 and as in normal use, the rear of 35 the same is provided with a pair of posts 3 between which extends a preferably round rod t. Also secured to said board, adjacent to but spaced Well from the right hand side of the same is an upstanding guide bar 5, which is perpendicular 40 to the axis and the rod 4, and against which a sheet of any suitable paper 6 is normally positioned, such sheet being either partly or entirely blank, graduated, or otherwise printed, or ruled, if desired, and being normally held in this posi- 45 tion by means of resilient fingers 'I and 8 which are pivotally mounted at 9 and I0, respectively, to the guide bar 5 and .directly upon said board I.

Said guide bar is provided with an upward extension II, which is provided in turn upon one 50 side-with a vertically extending slot I2, which slot, at its lower end enters a deeper recess I3. Into this recess normally extends the end portion I4 of a tubular gauge I5, carrying upwardly extending lugs I6 which are spaced apart at regu- 55 ydesired indicia whatsoever.

' lar intervals I'I, and preferably beveled at their upward corners I8 for a purpose hereinafter described. These lugs are for convenience secured within an elongated slot I9 in the top of the gauge l5 when in operative horizontal position, the end lug IBa. extending into the slot I2 .of the bar extension l I to prevent the gauge bar I5 and the lugs carried thereby from rotating angularly.

The opposite lug IBD for a similar purpose extends into a similar slot 20J in a post 2B carried by the board YI in widely spaced relation with respect to the guide bar 5 and its extension II. The vertical surface of the second post 20, facing the extension II, is also provided with a shallow recess ZI, normally extending into which is a ball 22, positioned in the adjacent end of the tubular gauge I5, and thrust yieldingly outward by means of a spring 23 within said member. With this construction said gauge I5 and the lugs carried thereby are normally positioned as shown in Figs. l, 3, 4 and 5, but may be -readily -withdrawn in order to replace Ythem with other similar substitute members characterized, however, by lugs of different widths and/or :spacing than those herein represented.

The board I is, furthermore, provided with va recess in which is'secured any Awell-known form of ink pad 24, vnormally spanned and protected by a removable cover 25, While there may be also secured to said vboard a suitable Yholder 26 for ink, such as is used to re-ink the pad 24.

Among the accessories of such a drafting device is a series of stamp elements, which are preferably composed 'of rubber, molded in any wellknown manner and -so molded as to represent any In the drawings forming a part `of this application, the :printing surface of the member shown in Fig. 7, aswell as `those represented by the consecutive impres- `sions shown -in Figs. 12, 13 and 14 are formed `to represent units of kitchen equipment, though yrepresent `or illustrate the great number of units which are designed to be assembled selectively, to form an-extensive up-to-date modern fpowerhouse switch board installation.

Each of the stamp members .comprises a `yielding body of Yextremely .live rubber or equivalent 21, a form of which has been designed `for use in the rpresent fdevice, such asis capable of ylong life and use Vwithout becoming distorted, wdue to shrinkage, warping, or other form vof aging or deterioration. The -outer active or impression face of this rubber body carried t.-e molded exA tensions 28 in relief, as in the case of an ordinary rubber stamp, while said body is directly cemented'to a plate `29, provided with a notch 3i) at one end and with a recess 3l at its opposite end adjacent to and extending into a normally upstanding angular portion 32. As `before indicated, there is provided a rather extensive series of these stamp members or units and the same, if desired, maybe carried in any suitable manner by the cover hereinbefore referred to, which in turn may be hingedly connected to the board I, but the `exact -construction of which is not considered an essential detail of the present invention.

For accurately positioning one of the rubber stamp bodies 2l with respect to its particular plate 29, there .is provided a jig, such as is shown in Figs. 8, 9, 10 and ll, comprising a body portion 33 surrounded on three sides by a slightly elevated ridge 34, between and against which a stamp body is positioned, and upon which latter a base plate 29 is then cemented, with the sides of the notch 3! of such plate straddling an upwardly extending guide post 35, forming an integral projection upon one end portion of the jig body 3. The opposite end of said jig body is provided with a recess 36, in which is yieldingly positioned an upwardly extending guide finger 3l, operatively positioned by means of a coil spring 38, surrounding an adjustable screw 3Q by means of which the tension of said spring upon said yfinger' is varied, as desired. When one of said plates has been thus operatively positioned and xedly secured to a rubber stamp member in predetermined standardized relation, invordel to produce at all times parallel impressions of the respective stamp members, as indicated in Figs. l2 and 13, the composite stamp unit may be removed irom ,the jig and is ready for use in such manner that the impressions made by consecutive stamps overlap only to the extent of the width of their laterally opposite marginal lines, which, therefore, in the final layout accurately coincide, as shown.

A stamp unit holder is shown in Figs. `1, 2, 3L

and 5a, and comprises an arm 40 carrying at its rear end a relatively heavy head 4 I provided with a transversely extending groove 42 upon its under side, and through which groove normally extends the rod 4, about the axis of which the arm40 is adapted to be manually oscillated by means of a handle 43, attached .to an extension 44 of said arm, which is preferably depressed or 4oilset in a plane beneath and spacedv from that of `the arm 4B, and .normally accurately parallel with the plane 45 of the board I and consequently that of the sheet of paper or the like .5. The under surface of the arm extension 44 -is provided rearwardly with an undercut lug 45, for receiving may be released by means of a lever 48 in any The under side of the forwell-known manner. ward portion of the arm 4Q, rearwardly of the extension 44, is also provided with a guide post 48 `from which extends forwardly a lug 49, which in turn normally enters one of the spaces I1 betweeen adjacent spacing lugs I6 upon the bar I5.

In the operation of this device with a sheet of paper 6, or the like, operatively vpositioned against the guide bar 5 by means of the resilient ngers l and '8, the arm 4S is raised and, if desired, entirely removed from engagement with the rod 4, whereupon any one of a series of stamp units is secured to the arm extension 44, as above described, and the arm replaced upon the rod 4, however, with the face of said stamp unit lin contact with the inking pad 24, against which said member is pressed in order to deposit ink upon the Araised surfaces 28 of the stamp. Having inked the stamp, the arm 40 is shifted longitudinallyupon the arm 4, and thereupon lowsheet, but ifY only vone of the units represented 'by such stamp is desired at this point in the particular layout, the arm 40 is raised from the frod 4 andthe stamp detached therefrom, being replaced by a stamp-representing another type of unit, after which the arm is replaced upon the guide rod, the second stamp is inked and thereupon impressed upon the sheet 6 adjacent to ori-'spaced from the impression 5U, after the notch 49 has been made to enter the proper space I1, either adjacent to the space previously entered, or, in fact, into any other of the several spaces provided for this purpose. After a series of such impressions have been made upon the sheet, such for instance, as the composite elevational layout shown in Fig. 12, the plan of the working surfaces of the units represented by some or all of the units sho-wn in Fig. 12 may be arranged in a separate row, as indicated by Fig. 14, spaced from the above-mentioned plan simply by shifting the sheet E forwardly or rearwardly in a direction parallel with that of the guide bar 5.

As hereinbefore mentioned, the stamp units represented are merely illustrative of an infinite variety which may be employed, but which in order to carry out the illustration will be identiiied insofar as they relate to kitchen equipment. Therefore, the impression l comprising Fig. 12 is that of an upwardly positioned closet space having a pair of doors 52, beneath which is represented a working surface of table 53, upon the top of a compartment normally closed by means of a door 54. In Fig. 13, the first two impressions 55 are similar and represent upper closets 52 beneath which is provided a continuous working surface 53 above pairs of vertically arranged drawers 56.

a vertically elongated compartment 64, which provides space adapted for cleaning and similar devices. Since the units represented in Fig. 14 correspond with the first six units of Fig. 13, they show the same working surfaces 53, the sink 59, drain board 62, a third working surface 53 and finally that of the range B3, the last unit of Fig. 13 not being shown in plan View as no working surface is provided by it.

Referring to Figs. l5 to 19, We nd that between and trunnioned in the supporting posts 3 is a bar 55 of polygonal and preferably rectangular cross section, said bar being provided with spacedrecesses 66, the spaces between their centers being equal to the width of the several rubber stamps or dies 21, representing the respective kitchen or other units in elevation, and also the width of the corresponding plan views 21a of such units. Slidable upon said bar is a block 61v having a channell 58 of thesame'width and general shape as that of the bar which extends thru it. One wallv of said block is pierced by an aperture 69 in which ispositioned a ball or the like 1U, which under the influence of a rsuitable spring 1l is normally forced yieldingly into any one of said recesses 66 selectively, it being understood that instead of the ball and spring shown any other desired means may be employed, for normally maintaining'said block in a given laterally adjusted position.

Secured to and `extending forwardly from said block; andi finnormalparallelism with the sur'- vits freee'nd with a `latch 14, equivalent tolthe latch mechanism 1 hereinbefore described, while the rear end of said arm is provided with an aperture 15, or equivalent means for attachment thereto of the reduced end 16 of a plate 11, which in turn carries the rubber stamps or dies 21 and 21a, and at its opposite end is normally secured to said arm by means of the latch mechanism 15. In this form of stamp or die supporting plate, it will be noted that said plate is provided with positioning means such as the recesses 2111 and 21e, for the reception of the respective stamp units 21 and 21a, respectively. Such a construction eliminates the need of providing a jig, such as that hereinbefor-e described, and insures the proper spacing apart of the elevation and plan View stamp units, their simultaneous use and equal impression upon a given sheet of paper or the like, thereby always insuring their proper association in related pairs, and also the proper alignment with each other and their registry and alignment with the impressions of adjacent units.

In reading and considering the above description and the appended claims, it is to be understood that various additional modifications may be made in the details of construction and operation of the device, without departing from the scope of the broad idea of the invention as conceived.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is:

1'. The method of making a drafting layout, which consists in using a series of stamps representing a given set of assemblable units, impressing one such stamp upon a receiving surface, then impressing the same or other stamps of the series upon such surfaces in sequence and juxtaposition, so that a portion of the second stamp registers with the impression made by the first stamp to represent the cumulative result ofthe elements which the respective stamps represent.

2. The combination of a base, a guide carried by said base, an arm having a groove adapted to receive said guide, a stamp, means to detachably secure said stamp to said arm, and a gauge fixed with respect to said base and operative to position said stamp in any one of a plurality of predetermined positions for impression upon a sheet positioned upon said base, While said arm is in longitudinal and angularly oscillatable Contact with said guide, and said arm, after oscillation out of engagement with said guide, then longitudinal displacement upon said guide, and reverse oscillation upon said guide into re-engagement with said gauge, being operative to so position said stamp as to make a second impression upon the sheet, having a definite relation with respect to said first impression.

3. :In a drafting device, :the Vcombination of a holder., with a gauge having spaced irregularities, means to normally support the opposite ends of said gauge, and means to yieldingly secure one ,end of saidvgauge with respect to said rst means.

adapted 4to oscillate angularly with respect to said base, a block slidable upon said rod, means to yieldingly maintain said block .in any one of a plurality of predetermined positions upon said rod, an arm extending laterally from said block, a plate, provided With a plurality of definitely spaced recesses, a plurality of related stamps carried by said plate and permanently associated in predetermined relationship by said recesses, and means to detachably secure said plate to said arm, the relation of the size of said stamps to the spaces between said recesses being such that a portion of one stamp registers with the impressionmade by another stamp.
