ORNAMENTAL METAL PLATE.

Specification of Letters Patent.

Patented J an. 15, 1907.

' Application filed October 12, 1906. Serial No. 282,620-

a citizen of the United States of America, and a resident of Washington, in the District of Columbia, have invented certain new and useful Improvements in Ornamental Metal Plates, of which the following is a specification.

This invention relates to certain new and useful improvements in ornamental metal plates, such as tile used for wall-finish, and

more particularly to sheet-metal plates procolor desired and well adapted for use in bath-rooms, lavatories, Pullman dining-cars, for metal ceilings, and other like uses.

The present invention has for its objects, among others, to provide an improved ornamental plate or tile of this general type which can be either set in cement, either singly or in blocks composed of a plurality of the plates, or nailed to a joist or other sup ort, or held in place by both of these met ods, the construction being such that a slide lockjoint is provided together with a plurality of clings for the cement formed by the interlocking of the plates.

A further object of the invention is to provide a tile or plate with a plurality of tongues evenly distributed about the edges of the same with no two tongues adjoining each other and so disposed that the plates or tiles can be readily and quickly placed together so as to break joints.

A further object is to form th lates or tiles with undercut engaging edges, W 'ch not only tend to increase the bonding of the tiles or plates in the cement, but permit of the ready compression of the joints to compensate for unevenness in the Wall, so the tiles or plates can be set or laid so as to present a perfectly even and smooth surface.-

Other objects and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the appended claims.

The invention is capable of embodiment in a variety of forms, some of which are herein illustrated, being at the present considered the preferable ways of carrying out the inventlon.

The invention in its preferred embodiment is clearly illustrated in the accompanying Fig. 5.

drawings, which, with the numerals of reference marked thereon, formfa part of this specification, and in Which- Figure 1 is a face view showing a number of'tiles or plates as they appear when placed in position. ig'. 2 is a cross-section on theline 2 .2 of Fig. 1. Fig. 3 is a perspective view of one of the plates seen in Fig. 1. Fig.

4 is a sectional detail through two of the plates, showing the under-inclined joint at the edges. Fig. 5 is a view similar to Fig. 1, showing a plurality of plates of slightly-modified form iniited together. Fig. 6 is a crosssection on the line 6 6 of Fig. 5. Fig. 7 is a perspective view of one of the plates seen in Fig. 8 is an enlarged cross-section through the same, showing how the inclined edges may be compressed to compensate for inequalities or unevenness in the wall.

Like numerals of reference indicate like parts throughout the several views.

Referring first to Figs. 1 and 3, l designates a plate of requisite size and shape, being .formed about its two sides and two ends with theflanges 2, as seen best in Fig. 3. Each plate is formed at one end at the center with atongue 3 and at the opposite end with the tongues 4, while upon the sides are thetongues 5. It is to be noted that these tongues extend substantially horizontally in a plane below that of the face of the plate, and these va rious tongues are disposed at e ual distances about the edges of the plate, t ere being no two tongues adjacent each other-that is, there is a space between each two tongues entirely around the plate. lhis is essential for the reason that it permits of and insures the proper assemblage of the plates without care on the part of the workmen and allows of the lates being laid so as to break joints, as will be clearly understood upon reference to Fig. 1. When the plates are laid in osition upon the wall, the tongues interlock as will be clearly understood by the dotted lines in Fig. 1, and, as will be seen from Fig. 2, spaces are provided into which the cement is forced as the plates are pressed in place on the well,

'thus forming additional clings for firmly bonding the plates in place. By reason of this disposition of the tongues the plates are locked together both longitudinally and transversely, and in assembling or placing the plates in position they are sure to come IOC so as to break joints, and, furthermore, the

' plates can be laid very rapidly.

In order to insure a better joint between the adjacent edges of the plates, and, further, to provide an a ditional lock or better union of the plates and to avoid unsightlyjo1nts,I providethe edges as at theflanges 2, with under-inclined walls 6, as seen clearly in Fig. 4, so that when the plates are in position the under-inclined wall of the one plate receiving the inclined adjacent wall of the next lplate forms a lock-joint between the two p ates, and, further, by reason of this under-inclined wall forming the recess for the reception of the adjacent edge of the adjoining plate the same may be readily com ressed by the hand to compensate for inequa ities orunevenness in the wall upon which plates are to be laid.

In Fi s. 5 and 7 I have shown a slightlymodified form of plate, embodying, however, the feature ofthe under-inclined edge above described. In this form theplate 7 has theflange 2 as in the other form and also the under-inclined wall 8 upon the one side and the outwardly-inclined flange 9 upon the op o site side, as seen most clearly in Fig. 7. 's plate has thetongues 9 projecting from the outwardly-inclined flange 9 and thetongues 10 extending from and integral with the under-inclined wall 8. Theflanges 10 at their junction with the under-inclined Wall 8 are provided with the elongated openings orslots 11, which extend through the under-inclined wall 8 for the reception of thetongues 9 on the adjoining plate, the object being to pass thesaid tongues 9 through theopenings 11 and then bend them over, as indicated at 12 in Figs. 5 and 6, so as to draw the adjacent edges of the two plates closely together and form a tight undercut joint between them.

It is deemed important that the coacting inclined walls be straight in contradistinction 'to being rounded to form a spring or frictionheld joint, as by my construction the tiles are more firmly drawn together and rigidly locked by the action of the cement which engages both members of the joint. Besides my construction permits of more readily placing the tiles together in proper position on the wall and in the cement.

In Fig. 8 I have indicated by dotted lines the manner in which the edges of the plates thus formed may be compressed by a malle, or generally by mere pressure of the hand, so as to compensate for any ine ualities or unevenness in the wall against w 'ch the plates are to be laid.

cameo The plates may "be made as ornamental in appearance as may be desired, and for tilework the face thereof is to be glazed or covered with enamel similar to the so-called metile now in use for similar work.

What is claimed as new is- 1. A metallic plate for the purpose stated formed at its opposite edges with straight inclined walls, one ofwhich is inwardly inclined to extend under the plate and the other inclined downwardly and outwardly from the plate to form with. adjacent plates a concealed clamping lock and joint.

' 2. A metallic plate for the purpose stated, formed upon opposite edges with tongues and at its opposite edges with inclined flanges one of which has its incline straight and extended under the plate as and for the purpose set forth.

3. A metallic plate for the purpose stated,

formed with flanges about its different sides,

the flange upon one side having straight inclined wall extended under the plate, and

with tongues evenly spaced along said sides.

4. A metallic plate for the purposes stated,

formed with flanges one of which has an inwardly-inclined straight wall extended under the plate and the other flange inclined straight downwardly and outwardly from the plate and with tongues said flanges and evenly space about the four sides thereof, with no two tongues directly adjacent.

5. A metallic plate formed with flanges, one of which has an inwardly-inclined straight wall extended under the plate and the other flange inclined straight outwardly from the plate and with tongues projecting therefrom and evenly spaced with a space between each two tongues, the opposite edges of said plate being constructed to form with' adjacent plates under-inclined locking-joints.

6. As an improved article of manufacture, an enameled metallic plate formed at its opposite sides with flanges each having an inclined wall, one of which is under-inclined, and tongues projecting from the outer edges neath the a jacent ed e of an adjoining tile and to form therewit undercut engaging edges and a concealed clampin slide lockj-oint with oppositely-disposed c ings for the cement.

of said flanges to support and extend be- ALFRED DU MONTIER.
