To alZ'whom it may concern: 7

Be it known that I, Gnonen S. KNar'r,

a citizen of the United States, residing at La Grange, in the county of Cookv and'State of Illinois, hav'einvented-certain. new and a useful Improvements in Metal Base-Boards, of which the following is a specification.

My invention relates to improvements in metal base boards and has especial reference to means and appliances for joining adjacent ends of sections of such boards.

The object of my invention is to generally improve devices of this character.

Other and further objects of my invention will become obvious, to persons skilled in the art, from a consideration of the following description when taken in conjunction with the drawings, wherein Figure 1 is an isometric perspective of a portion of one section of the board and a connecting fitting for adjoinin sections for continuing the face surface 0 the sections around an inside corner. Fig. 2 is a section of the finished wall after the plaster has been applied thereto. Fig. 3 is a section taken on line 3--3 of Fig. 5. Fig. 4 is a sec tion taken on line 44 of Fig. 5. Fig. 5 is a section taken on line 5--5 of Fig. 4.

In all the views the same reference characters are employed to indicate similar arts. P In my Patent No. 1,143,283 granted to me June 15th, 1915, I have shown, but not claimed, means for joining contiguous metal base board sections. In this, my present application, the claims are directed to the castmg, or fitting for connecting proximate ends of the sheet metal base board sections at corners of a room.

In the resent embodiment the adjacent sections oi the board are designed and intended to be secured to the angle plate or fitting before the assembled parts are fastened to the wall.

In the illustration 10 is a sheet metal base board, having a vertical plane face portion 11 and curved face portion 12. It is rovided with the mortar receiving per orations 13 and 14 for introduction of the mortar or plaster behind the face of the board as more clearly shown and claimed in my former patent.. L

The upper margin 15 is provlded wlth gerforatlons 16 and 17 for attaching the" card to the side, while the lower portion of mn'rar. Bass-scam).

Specification of Letters Patent. ,Patemted New. 21]., lijfilifi. Application filed September 7, 1915. Serial No. 49,310.

the board is provided with a margin 18 that is to be in contact with the wall, having perforations 19 and 20. The upper margin is inturned, as at 21, and the lower margin is downturned, as at 22. An angle or fitting 23, is provided with a vertical curved surface 24 which is practically a continuation of the surface 11 of the section 10, and an outwardly curved surface 25, which is ractically a continuation of the curved surace 12 of the section10. The surfaces 24 and 25 project forwardl of the surface 26, to an extent equal to tlie thickness of the material of which the section 10 is composed so that the part 26 serves as a backing for the part 11 of the strip. Projections 27 and 28 extend laterally of the part 26 and above through a similar perforation of the part 15' of the board, thereby holding the fitting in contact with adjacent edges of a board sec tion. Similar screws 33 pass through the lower portion of the board member and into perforations 34, contained in the lower edge of the parts 26, 27 and 28 of the fitting, thereby securely holding the fitting at top and bottom limits to the attached base board section. A curved perforation 35, within which to key the plaster, is made in the upper portion of the fitting, the edge 36 serving as a ground to which the plaster is finished.

The floor may be finished to the upper edge 37 of the part 22 or to the lower edge 38 as desired. If it is a composition floor, as shown in Fig. 2, it is preferably finished to the upper edge 37, so that the mortar, or other composition, may pass through the perforations 14 behind the lower portions of the board.

It will be observed that the upper edge of the board passes behind the fitting 23 while the lower edge is secured by the same means in front of the fitting. By this means the fitting is held in place against the wall by the fastenings 39 that pass through the body portion of the board and at the lower edge the fitting is supported by the shoulder 40 of the board section. Thus the shoulders provided at the upper and lower ends of the fittings prevent transverse shifting of the parts after they have been placed in position. 7

Having described my invention, what I claim is":

A fitting for joining sections of sheet metal base boards having upper andlower longitudinal marginal portions bent rearwardly and then outwardly into the same plane-for attachment to a wall, said fitting comprising a body part having a face surface shaped to form a continuation of the exposed surface of the base board, integral end numbers projecting from the body part to underlie the rear face of the base board intermediate its marginal portions, projections extending from the body part near its upper end and spaced vertically from the end numbers to form horizontally'extending openings therebetween to receive the upper rearwardl extending marginal portion of the base oard the upper outwardly bent edge portion of the base board-lying at the rear of the projections, and fastening means taken through the projections and outwardly bent edge portions of said base board.

In testimony whereof I hereunto set my hand in the presence of two subscribing witnesses.
