Fig. 14'is a view similar to Fig; 11, but showing a modification in the structure of the formving blade; and

the base of the devicefor cooperation with the swinging, cutting blade thereof.

As shownin Figs. 1-6, the base or frame of the device which is preferably formed of cast aluminum or othersuitable material, is generally desig; nated 2B. This base is provided with a pair of longitudinal; sidezflansessll and. fl iwhichz articularly adapt the device for support on the knee, for instance, of an operator or for support on any flat surface. The central portion of the base is provided with a plurality of longitudinal recesses 23, 24, and 25 which are adapted detachably to receive and house extra forming blades, when not in use. Secured to the upper fiat surface of the base 20 by means of screws 21 is the top plate 26 provided with a scale 28 for convenience of locating the tile to be re-sized, re-formed and/or re-shaped. The scale 28, may, for instance, be etched in the top plate 26.

As shown particularly in Figs. 1, 2, and 6, the top plate 26 does not extend entirely to the righthand edge of the base but terminates a predetermined distance therefrom in order to provide accommodation for the forming blade generally designated 30 in Figs. 1, 2, 5, and 6. This forming blade is adapted to accommodate tile of extreme width or dimensions as, for instance, a tile 6" x 6".

Pivotally secured to the base 20 by means of screw 48, nut 4| and friction washer is the cutting blade 42 which is swingable about the screw 40 as an axis for cooperating with the forming blade 30 to cut a formed tile and simultaneously re-form the edge thereof with a chamfer, bevel, or flange corresponding with the chamfers, bevels or flanges on the other edges which were formed when the tile was manufactured.

The cutting blade 42, especially as shown in Fig. 3, is provided with an arcuate cutting edge 43 so located and of such extent that the cutting edge presented to the tile throughout the cutting operation is of appropriate angularity to secure the ultimate cutting efiiciency. The blade 42 is operated by the handle 44 which is pivoted about the screw 45 extending through an aperture in the free end portion of the blade 42. Wing screw 46, passing through suitably located apertures 4! or 48 of the handle, makes it possible to secure the handle 44 to the blade 42 in two positions, a third position being obtainable by passing screw 45 through aperture 48, as shown in Fig. 3, in order to facilitate operation of the blade 42 by an operator irrespective of the support or position of the base 20 of the device.

As shown in Fig. 2, the base 20 is provided also at its upper end with recesses similar to recesses 23, 24 and 25 adapted detachably to support the forming blade 38 and a wrench 49 for adjusting screw 56.

The elongated recesses adapted to support the forming blades shown in Figs. 2, 7, 8 and 9 and wrench 49 all comprise elongated slots under which are similar narrower slots 5| each housing a friction spring 52 which is secured by means of a screw 53 to the base 26 as shown in detail in- Fig.4.

As shown in Figs. 2 and 5, a groove 55 is provided adjacent the righthand edge of the base 28 which groove 55 facilitates the removal of the forming blades 3|l---3|l (Figs. 1-9) from the base 20 after the lock screw 56 is released to make possible the changing of the forming blades as desired.

The forming blade 30, as shown in Fig. 2, comprises an elongated plate member provided with an aperture 39 receiving the lock screw 56 by means of which the blades are detachably secured to the base 20. Threaded apertures provided at suitable locations in the base 20 receive the lock screw 56 in its various positions for securing the forming blades SO-40 to the base. The forming blade 30 (Fig. 2), for instance, may be adapted 4 to handle a tile of 6" x 6". This forming blade 30 is provided at its outer or righthand edge with a step 3| of width approximating very closely the thickness of the metal from which the tile is formed. Adjacent and inwardly of the step 3|, is a chamfer or bevel 31 which is complementary with the edge chamfers, flanges or bevels formed in the tile when originally manufactured in the factory. Extending from the ends of the chamfer or bevel 31 are the end bevel or chamfers 38 which are disposed at acute angles to the bevel or chamfer 31 as shown in Fig. 2. The cut away or swept back relationship provided by this acute angular relationship between the end chamfers and bevels 38 and the bevel or chamfer 31 permits angular cuts to be made with the forming blades 30, 3|] and 3|] as illustrated in Figs. 12, 13 and 14.

The forming blade 30, as shown in Fig. 2, is also provided with a pair of circular apertures 33 which are adapted to receive the triangular upper sections of the locating studs 28 The longest forming blade 30, as shown in Fig. 2, is also provided with three circular locating apertures 34, 35 and 36, which cooperate with similar triangular upper sections of lock screws or studs 2|) accurately to align the forming blade 30 with respect, to the base 28 and cutting blade or knife 42.

The afore-described lock screw 56, with its 00- operating screw threaded aperture or socket in the base 20, prevents endwise movement of the forming blade 30 with respect to the base 28 and its top plate 26.

The forming blades 30 and 30 of Figs. 7 and 8 are similar to the above described forming blade 30 of Figs. 1-3 except of lesser length, corresponding parts being numbered accordingly.

The forming blade 30 however, in addition to having the apertures 34, 35 and 36 omitted because of its reduced length, has the end bevels or chamfers 38 disposed at right angles to the front bevel or chamfer 31, adjacent the step 3|. This arrangement is made because the trim tile to be cut and re-formed by the use of this blade 30 is relatively narrow and hence is cut on-thesquare.

The trim tile, of which a fragment is shown and designated 60 in Figs. 10 and 11, is stamped or press formed from metal sheeting of thickness corresponding with the width of the step 3|. As manufactured, the trim tiles are rectangular and of desired length, being provided with marginal flanges 6| forming chamfered or bevelled edges. With the tile 66 in the position of Fig. 10, actuation of the knife or cutting blade 42 will sever the tile as shown in Fig. 11 while simultaneously forming a new flange or bevel 6N corresponding with the original flange or bevel 6|. The bevels or flanges 6| and 6 l are complementary with the bevel or chamfer 31 of the forming blade 38.

As shown in Figs. 12 and 13, when either forming blade 30* or 30 (or 36) are used, the swept back end bevels or chamfers 38 permit the tile to be cut at desired acute angles up to 45 degrees.

The tile being cut in Fig. 12 is designated 62 and is of substantially greater width than the trim tile 66 described above. It is shown in dash lines in position for a square cut, and in full lines in position for an angular out. As will be understood from Figs. 10 and 11, regardless of the angle at which the cut is made, the flange or bevelled edge 63 will be reproduced (as 63 on the cut or severed edge simultaneously with the'cutting or severance (Figs. 14 and 15).

The rectangular tile shown in Fig. 13 is designated 64 and its flanges or bevelled edges are designated 65. This figure, when taken with Fig. 12 illustrates that the tile can be cut at acute angles up to 45 degrees in either direction because of the provision of the swept back bevels or chamfers at both ends of the forming blades 30, 30 and 30'.

Fig. 14 illustrates a variation of the structure of Fig. 12 wherein the forming blade 10, substituted for the forming blade 36*, is thinner than the blade 30 and its top surface lies flush with the top plate 26 of the base or frame 20. The

forming blade 70 terminates inwardly of the righthand edge of the base whereby a step is formed between the righthand edges of the blade 10 and the base 20, outwardly of the bevel or chamfer 31 of the blade 10. This step corresponds, functionally, with the step 3| of the forming blades 30, 30 30 and 30.

In the embodiment shown in Fig. 15, the step 3| is omitted from the forming blade [0 which is of the same thickness as the forming blade 30 (Fig. 12). However, a step 12 is provided at the under side of the righthand edge thereof, which step rests upon the upper edge surface of the facing plate 13 which is secured to'the righthand edge of the base by means of screws 14.

From the above description it will clearly appear that we have provided new and improved devices which re-form and/or re-shape metallic tiles having flanged, bevelled or chamfered edge portions by a single operation wherein edge flanges, chamfers or bevels are formed at or adjacent the new cut edge simultaneously with the cutting of the edge and whereby each edge of the re-shaped, re-sized or re-formed tile is similar.

It will further appear that these devices are readily portable, of simple and fool-proof construction, compact and extremely efficient in operation fulfilling a long existing need for means effecting the re-sizing, re-forming and/0r reshaping of marginally bevelled metallic tiles at the location of their application to buildings and other structures, with ease and convenience and with such efficiency and neatness that the reformed and/or re-shaped tiles can be distinguished from the fully factory formed tiles only with great difliculty and only by their shape or size.

It is, of course, to be understood that the above description is merely descriptive and nowise limiting, and that we desire to comprehend within our invention such modifications as are included Within the scope of the appended claims.

Having thus fully described our invention what we claim as new and desire to secure by Letters Patent is:

1. In a device for re-shaping sheet metal tiles having flanged edges, a base having an elongated straight edge, a cutting blade pivoted to said base and having a cutting edge swingable in a substantially planar path past said straight edge of said base, and a forming blade detachably mounted on said base for cooperation with said cutting blade, comprising an elongated plate member with a bevel spaced from one lateral edge a dis tance approximating the thickness of the tile forming sheet metal by a step of appropriate depth, said bevel being complementary with the original edge flanges of said tiles and parallel with the straight edge of said base, and a pair of end bevels similar to the aforesaid bevel leading from the ends of said first named bevel, said cutting blade when cutting a new edge simultaneously forming adjacent edge portions over said bevels to form edge flanges while progressively severing the sheet material forming said tiles.
