(Clam-436').

This; invention. relates. to. what: is; knowm im the: ant. to: which it: applies as a: plastenens. angle plane, and has: reference. more particularly to. a. tool whereby the angles. or corners; of? walls: plastered. with: the first: or: brown coat: may; be planed. down for; the punpose' of. trueing; up. the angles and; for removing from. the. surfaces: pienem of; sand; plaster. or-trowelmarksandz. ridges. that would. interfere with. the. application and: smoething. up: of; aefinish. coat of plaster.

It is the principal object of my: invention-- to; Provide an angle planes of: an improved form, comprising a. main: frame. member to. which a; handle is. attached and which a; plurality of: wall planing blades: are: mounted; in. an. angular" relationship. bothi with; respect to. theuhandle andi tn. each other and; which; in. a. planing: action; wlih simultaneously scrape or act on the plastered: surfaces. Eurthermore',.it1isian object of the invention to provide an angle plane equipped with a plurality of blades so that thework of planing down. or trueing up an. angle. or surface. man be greatly speeded up and moreeifectivelyraccoms plished.

Still another object-of myinvention is to provide an. angle plane wherein the blades are-self aligning. which will wear evenly. and willuzetain their sharpjoorners. Furthermore, bladesz that are mounted-in a frame in suchsmanner thatbthey may.' be readily removed for. replacement; when such is desired.

Still further objects of my invention reside in the details of construction of the various parts, in their combination and in the mode of use of the tool, as will hereinafter be fully described.

In accomplishing the above mentioned and other objects of the invention, I have provided the improved details of construction, the preferred forms of which are illustrated in the accompanying drawings, wherein- Fig. 1 is a perspective view of a plastere'rs angle plane embodied by the present invention.

Fig. 2 is a perspective view of the same, as shown in an inverted position.

Fig. 3 is a top or plan view of the plane.

Fig. 4 is a side view of the same.

Fig. 5 is a plan view of an end portion of the plane as seen from the under side, showing the angular direction of the blades as applied to the main frame and showing a slot as formed in the frame member for mounting one of the blades.

Fig. 6 is a cross section, taken on the line 6-6 in Fig. 4.

Fig. '7 is a face view of a planing blade designed for planing a cove surface.

As observed in Fig. 4, the handle. isvof substantial) lengtlband i's symmetrically-locatedorrthe frame.

Formed through the lower portionzof the frame.

bycutt'lngftlirougit its opposite sidewall portions:

are; anguiarly: d'irected slots 21),. one of which. is well? showm in Fig: fiiatr-thedeft hand' endi or the: view. The slbts: are evenly. spaced apart" along: the-frame member; andialtemate slots are inclihed im opposite-' dlreotions; each" at. an angle ofiabout thi'nt y degrees'with respect tothe longi tudinal edge of the frame. Set within each of the slots is a planing or scraping blade 22, all blades being of the same size and shape and of rectangular form and formed from metal of a kind suitable for the intended use. In the present instance, I prefer to use sheet steel of about twenty-two gauge. All blades have their end and longitudinal edges cut straight and square, and the blades are of such length that their end edges will terminate close together and substantially in alignment, as will be understood by reference to Fig. 3. When seated in the slots 22 of the frame member, all blades will be supported with their scraping edges in the same planes.

It is to be pointed out that, as an additional advantage in the use of the present device, the end edges of the blades lie beyond the end and side limits of the frame member ID. This will be understood best by reference to Fig. 3, wherein it is noted that the ends of the blades extend substantially beyond the side edges of the frame member Ill. Also, the ends of the blades that are mounted at the ends of the frame member extend beyond the planes of the end surfaces of the 3 frame. This insures that the frame will at no time interfere with a'planing action. Furthermore, the blades extend sufficiently to the sides of the frame and handle that there is no danger of the user rubbing the wall with his hand when grasping the handle member.

In order that the blades may be held securely in place, each is provided'centrally with a hole or opening 25, and when the blades are seated in proper position in the frame slots, these holes will be in alignment and in position to receive a'lock ing rod 28. The arrangement is such that the locking rod will be seated within the lower angle of the tubular frame member, as well shown in Fig. 6 and will hold all blades firmly seated in their mounting slots. 4

It is to be explained further that the arrangement of parts is such that the blades 22 may be inverted or reversed in position and secured by the rod 28 applied through the same holes in either position of use. Should it be desired to change the blades, it is required only that the rod be withdrawn. This releases all of the blades, and they may be readily lifted out of their retain? ing slots.

It is also anticipated that blades of different shape than those shown in Fig. 6 might be employed, for example, a blade as at 30 in Fig. 7 formed with a curved scraping edge 3| adapted to fit within the curvature of a cove molding-or ceiling. Blades of other shapes also might be employed to meet special conditions.

Angle planes so made are long wearing, easy to handle, light in weight and especially effective in use. The angles of the blades will wear sharp and square regardless of the extent of use and will be self-aligning in that should one extend slightly beyond another at the beginning of use, it will readily wear or adjust itself so that its edges will be perfectly aligned with the edges of others of the plane.

Devices of this character may be madev in different sizes and in different proportions than herein illustrated, and also may be equipped with varying numbers ,of blades. Furthermore, the frame member H) might be made of wood, plastic, or of cast metal, such as for example, aluminum. Therefore, it is not desired that the following claims shall be restricted to the details of construction herein shown but that they shall be given an interpretation that is commensurate with the scope of the invention which has been square or of other appropriate shape, and furthermore, it might be made of wood or plastic.

Having thus described my invention, what I .claim as new therein, and desire to secure by Letters Patent, is:

1. An angle plane of the character described comprising a rigid, centrally located longitudinal frame member of tubular form, a handle fixed thereto at its outside of the top wall, and there being slots cut through the frame member across its inside, alternately inclined in opposite directions, scraping blades disposed edgewise in said slots,.and extending substantially to opposite sides of the frame member, each being made of resilient metal and havinga longitudinal scraping edge and scraping edges at opposite ends, said longitudinal edges all being in the same plane, and scraping edges at opposite ends being in the same planes; each of said blades having a hole therethrough, and a blade locking rod seated in said tube against the bottom wall and extended through said holes of the blades to secure them seated in their mounting slots.

2. A device as in claim 1 wherein the tube is of triangular form in cross section, and said slots are cut through converging walls thereof, and said blades engage at their top edges against the base edges of the slots and said locking rod is seated in the angle formed by the converging walls.
