makeshift construction; that is, they are individually made by the plasterers on the job for performing the task at hand. Unless the plasterer is a fairly skilled mechanic, these types of molds are ordinarily of a mediocre type, and consume much time and skill in the making thereof only to be discarded later. The purpose of the present invention is to provide a permanent type of tool of a diversified form, characterized by a multiplicity of details mechanically allied into a new organization such as will fulfill the requirements of a tool of this kind in a highly satisfactory and economical manner:

The various elements embodied in'this new composite tool will become more readily apparent from the following description and drawings. In the drawings:

called to the numeral 11 whichdesignates the plate which 'may be structurally distinguished as a right angled form. A principle feature of this plate is the longitudinally extendingshaping edge12.. As shown in Figure 5,thisis provided with a plurality of distinguishable bolt holes .13,"14= 15 and 16. This form is used when twoflat walls meet at an angle greater than a right angle where it is desired to produce .a rounded effect and the form may be used by itself.

'It will be observed that along one edge is a laterally directed runner flange 17 designed to be placed on a-rail or thejlike (not shown) to permit convenient operation in a conventional way. Secured bya pivot and retain: ing bolt 18 in'the hole 15 is a blade or angle adjusting le 19 which may be swung to the 1 dotted out-o -the-way positionshown in Figure 1 or which may be adjusted 1130 various angles with respect to the shaping edge 12 to eflect different angular shaping.

, The part llin'addition to serving as a form or tool in itself hasfthe additional function of providing a mounting for a detail which is hereinafter designatedas a template and indicated by the numeral 20. This template asshown in Figures 6 and 7 comprises a substantially plane plate having an, approximately V-shaped notch 21 formed in-one edge thereof. 7 j- At the apex or crotch portion of the notch is a bolt hole, 22 to accommodate the; matrix 23. The matrix issomewhat in the natureof a star wheel and is 'adjustably fastened inplace by ascrew, bolt, or the like 24 as shown in Figure 1. Inthis'connection it will be observed that the matrix embodies a straight edge 25 and a series ofdistinguishable curvate edges 26, 27 and 28 respectively whichmay be adjusted to co-operate with the front por tion of the notch 21 :in a'selective manner, ac

cording to the shape of the crownportion of the molding desired. 1 I The oppositeedge of the template is fashioned as at 29lto form what may be designated as an ornamental pattern which is useful when r in, the position; represented -in- Figure '6. Adjacent this pattern are bolt holes 30. which match the aforesaidlholes 13 and '14 t0a -U' commodate fasteners 31 when in the position shown in Figure 1. Incidently the configura tion of the pattern 29.1nay be of variegated construction for different classes of work. In fact, any number of diiferent types of templates maybe supplied with the tool 'I now call attention to the numerals 32 which designate attaching brackets these having an attaching flange 33 secured to the form plate 11 and having spaced parallel wings34= apertured to permit the template to be se-" cured therebetween in the relationship shown in Figure 6. Thespecial template 20 is useful with or without the runner form .11, and it may be attached'thereto in the position shown inFigure 1 or in the right angular position shown in'Figure 6. As a matter of fact, it is susceptible of use by itself.

Particularly do I wish to emphasize the presence therein of the ornamental pattern 29 aswell'as the .V-shaped notch 21 and the associated adjustable matrix 23 co-operating snection with the drawings.

with the V-shaped notch.

Isalsowish to emphasize the individuality. of use ofthe form 11 as well as its use in combination with the template. Then too, I call attention to the presence therein of the attaching bracket 32 to permitthe positioning of the template thereon. Moreover, I expressly note the somewhat curvate shaping edge'12 and the co-operative 'an'gleadjustinglegs 19 associated therewith. These details co-operate in such a manner as to render the structure usable in a wide range'ofplastic formation.

It is thought that persons skilled in the art to which the invention'relates will be able to obtain a clear understanding of the invention after considering the descrpition in con-' Therefore, a more-lengthy descriptionis regarded as un necessary, I

Minor changes in "shape, size, and a rearrangement; of details coming within the field of invention claimed may be resorted to in actual practice if desired.
