` 130mm. (on assenti 1 i This invention relates generally to templates and gauges and more particularly it relatesto templates andv gauges wirrich mair be adjusted to reproduce the profile or measuementsy ofr an irregular surface.

Inthe crafts of-4 carpentry, carpet laying, iloor tiling, ship carpentryL and may othersthere is the frequent problem of transferring the outline on profile of a fixed,v relativelyv immovable object suoli as a doorffra-me to a floor1 covering such as tile orlinoleum floor coveringv so that; the tile or: linoleum may; be ttedaccurately to the contou-rof#` the door frame; It is conventional praeticeon. the part ofr craftsmen to take measurements for' cutting the I i'oor covering which requiresthe expenditure of; appreciable periods of time. InA fact, atime study`v wouldf show that the time expended in iitting; floor covering to a single doorframe equalsthe time eiipenclml.V in laying the fioor covering around the,v entire circumference-ofa room.

The prior art includes certain forms of gauges or templates which may be adjustedk'to. conform with the profile of an irregularly shaped object, but-these prior artdevices d Ilotpresent a cf; n .y tinuoussurface adapted toy guide'the continui,- ous motion. ot aY pencil or other marking device, priordevices` usually comprise a plurality o# on pointers which mag be adjusted or manipulated toa-but a plurality of pointsenly on an irregulary surface. Thus, only these points may be. transferred: to another surface for purposes of reproduction. Such devices cannot reproduce accurately the position of substantially euery-:point on an irregular surface.

Accordingy-155'I it i-sthey principal object of' this invention to provide a composite template or gaugewhich maybe adjustedto haveI a plurality ofdifrerent profilesandwhich forms acontinuous.v surface ion guiding a marking' device.

Anothen object ofl this invention is togprovide a composite template or gauge having a plurality of individual,l plane, pifoletemplates off vari'` ous shapesA and; a clamping devicer for clamping .thetemplatea adjacent to one another-or in ever'- lappingA relation toY one another' to'form a con;- .tinuous surfacevfor gfuiding-a mark-ing device.

The press or clamp I- includes a casingJ having a base member or fixedr jaw il, end blocks: i12 and |"3-, and bridge t5. The bridge: isv slotted at- HI to accommodate a leverA td, the purposevof which wi-llbe described. subsequently. Lever-I3 may be pivoted to bridge t5; by means: of,l for example, ampi-1nV 9- extendingrr into on through the downwardly' extending:Y ears 2 lf formed integrally with bridge t5. Lever i8- extends beyond its pivot to fhorrna cam sur-face- '2-3l which isy c entriowith respect to theA pivot as illustrated the drawing. Y

For clamping the individualJ proiiile. templates in anyA desired position there. is providedan elongated channel on movable jaw 2f5 #Qwhoh isattached a similarly -elongatedfresilientcushion 26. Cushion 26- shouldbe sumei'entlyJ resilient to accommodate the profile plates inoverlapplng relation* andfits surface should have` sufficient friction toprevent.- movement ci" the prolef templates atten they are clampedy ina desi-red posi;-

tion. Rubber, cork or similar materials have the desired characteristics. For applying pressure from lever I8 to the channel 25 there is provided a clamping block 21 having an upwardly extending column 28 (Figure 4) which is adapted to abut the cam surface 23 of lever I6. Block 21 is provided with a pin 29 which is adapted to rest in any one of the slots 3l, 32 or 33. The upper surface of block 21 is dividedY into three portionsj35, 36 and 31, portion 36 being higher than portion 35 and portion 31 being higher than portion 36. Thus, block 21 may be shifted longitudinally to place pin 29 in slot 3I, 32 or 33 and align portionv35, 36 or 31 with cam surface 23, thereby to insure pressure contact between surface 23 and one of the surfaces 35, 36 or 31, regardless of the spacing between cushion 26 and base II.

The profile plates 2, 3, 4, 5, 6, 1, 8 and 9 are provided for insertion between base II and 'cushion 26 so that they may be adjusted as shown in `Figure lV in abutment with the door frame-46 with each of the prole plates aligned with each of the surfaces ofthe door frame. The plates preferably are of assorted lengths and widths and also' of assorted shapes. For example, there may be rectangular, triangular and curved shapes. Also, there may be plates of irregular linear form such, for example, as plate 9 which has they advantage that surfaces of greater length than the length of base I I may be reproduced. In general, itmay be stated that the shapes of the profile plates are dependent on the nature of the job on which the template is being used.

T he utility of this device may be further increased by providing ruled graduations on the base tIIas illustrated at 4I and also on one or several 'of the plates 2, 3, 4, 5, 6, 1, 8 and 9 as hillustrated at 42, 43 and 44. Thus, depths, lengths and angles on the door frame may be measured.

L ',To utilize this invention, lever I 8 may be placed inl approximately the position shown in Figure 3 and any or all of the desired profile templates 2, 3, ,4,"','6, 1, 8 and 9 may be'inserted between ,base lI'I and cushion 26, either side by side, or in overlapping relation, as shown in Figures 1 and 2`. Then the press or clamp I may be placed ad- .jacent't-he door frame and the prole plates may Ibe .manipulated-by the fingers of the user until .each plateisfin -such a position that its end or side, as the case Vmay be, is flush with the opposing'surface of the door frame. Then lever I8 4may, be moved tol itsclamping position where cam surface-23 `exerts full pressure on one of the surfaces 35, 36er 31 of block 21, as illustrated 'in -Figures l andA 2. This moves jaw 25 down- `Wardly and forces cushion 26 into frictional contact with each of the profile plates whereby they :are held firmly in final position. Thisis insured by the vprovision of the surfaces 35, 36 and 31 of vvarying heights. For example, if only two prole plates are used there is minimum spacing be- .tween cushion 26 and base I I, particularly if the plates do not overlap. In this case, block 21 is moved to place pin 23 in slot 3| thereby to align .surface 31 with cam surface 23. If, on the other hand, eight or ten prole plates are to be used in .overlapping relation, as illustrated in Figures 1 and 2,-itmay be necessary to move block 21 to such a position that pin 29 may rest in slot 32 or :3:3.to align surface 35 or 36 with cam surface 23. `Thus; there is provided sufficient spacing between cushion 2lif and base II to accommodate ka comparatively large number of prole plates in any desired Vrelative positions.

Having clamped the profile plates in the proper position, the user of this device is provided with a complete profile of the outline of the door frame. By laying the clamped profile plates on a piece of floor tile or other floor covering, the profile may be traced on the tile so that the tile may be cut accurately to fit the surfaces of the door frame. `It is to be noted'that this invention provides an adjustable template'which forms a continuous guide for tracing purposes whereas prior art devices of this type establish only spaced points of the surface to be reproduced.

When it is desired to utilize this invention as a gauge for taking measurements of an irregular surface, therulededges such as 4I, 42 and 43 may be read and the readings may be added or subtracted to compute the dimensions which are desired.

For the purpose of illustrating the use o1' this invention, the description refers to a door frame and the laying of tilecr other floorcovering. It should be understood however that, there are many other uses for this invention in otherelds such, for example, as in the crafts of shipbuilding, aircraft building, plumbing, electrical Work and: machine work. v

In connection with the profile plates, it is to be noted that they may be prefabricated to provide a set of standard plates, and the workman on a particular job may fabricate for himself special plates of sheet metal or other suitable material especially adapted for his immediate problem.

While there has been described what is at present considered the preferred embodiment of this invention, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of this invention, and it is, therefore, aimed in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of the invention.
