To all whom t may concern:

Be it known that I, EDWARD J. MORRIS, a citizen of the United States, anda `resident of Newark, in the county 4of Essex .and State of New Jersey, have invented certain new and useful Improvements in Knives, of which the following is a specification.

This invention relates to improvements in knives, and more particularly to the manufacture thereof, the object Aof the invention being to provide an improved knife which may be readily manufactured, and by Vmeans of which the manufactured article may be of approved and advantageous structure and design.

For this purpose my invention consists of the improvements set forth and finally pointed out in the claims.

In the accompanying drawing, Figure 1 is a side view of my improved knife, Fig. 2 is a vertical transverse section taken `on line 2 2 of Fig. 1, Fig. 3 is a similar section with the outer plates removed, Fig. 41 has the inner plates also removed, leaving only the knife body, and Fig. 5 shows a vvertical transverse section of the knife blank, from which the knife body is obtained.`

Similar reference numerals indicate corresponding parts throughout the various figures of the drawing.

Referring to the drawing, and more particularly to Fig. 1, a side -view of the knife is shown therein. The knife blades 10 and 11 are pivoted at 12 and 13 to the back-bone or spring 16 of the knife. rlhe knife blades 10 and 11, with the spring or back-bone 15 and with side plates 17 and 18 secured to the spring or back-bone 15 by upset portions 19, form a knife blank or knife body, which are imported in large quantities into the United States, but which require further working to be put into a marketable condition. Hitherto it has been customary to apply to the outside of these plates 17 and 18 exterior plates, and aflix the exterior plates to these interior plates 17 and 18 by means of solder or riveting or the like, but in these cases, the comparatively thin outer plates would not fit snugly into the inner plates 17 and 18, and therefore, on being struck, would be likely to be indented, and the knife thereby injured and made of comparatively less value. Y

` My invention consists in removing completely the side plates 17 and 18 of the knife blankor body shown inf Fig. 5, and securing to the knife 4back or spring 15, inner plates -of base metal, such as shown by 30 and 31 in Figs. 3 and 4. These plates 30 and 31 are secured to the spring or back-bone 15 by a suitable upset portion'19, which passes between the same.

'Vith the parts shown in the yposition shown in Fig. 3, the outer Vor exterior plates of precious metal-are thereupon applied, the con-tour of which precious metal exterior plates -is exactly the same as the contour of the inner plates 30 and 31, so that when said exterior plates are applied to the interior plates, a very snug fit of all `its portions is obtained. This is clearly shown in Fig. 2, and shows the exterior plates 32, which are made of rpreciousmetal, as gold, silver,plati num or the like, secured to the inner plates 30 and 31, and snugly fitting thereto. These exterior plates are :provided with ianges 37, so as to completely extend over the 'inner plates. rl`he exterior plates 32 and 33 are either cementedl or ysoldered to the exterior plates 30 and 31, so that a very smooth connectionlis obtained.

ln the event that it is desired to have the exterior plate ,provided with ornamentations in the form of embossments, then it is necessary to provide the same with configurations on the interior plates. This is shown clearly in Fig. .2, where the inner plates 30 and 31 are provided with depressions 39 to take yup the embossments 36 of the exterior plate. By this co-acting of parts, the exterior plate lits very snugly to the interior plate, and in the event that the exterior plate should be struck in any manner, it will not become indented or injured as was the case heretofore.

By the means proposed, a knife is obtained which has better mercantile qualities and advantages than the knives known hitherto in the art, and a very compact and eflicient knife is obtained. An economy in the saving of valuable metal is obtained, as the exterior plate can be made very much thinner and of better metal than the exterior plates heretofore, because the co-action of the inner plates fits so snugly to the exterior plates that it acts as a support for the recious metal outer shell, whereasin the ol knives such support was not had, and therefore the exterior plate or shell had to be consider ably thicker. Furthermore, an improved appearance is obtained, as a Hatter and thinner knife is enabled to be produced than was possible hitherto. Also a firmer and more compact knife is obtained, and in view of the fact that the precious metal shell is backed up by the inner plate or support, it is not likely to be indented.' Furthermore, by the improvements described a knife may be produced which will assay at a desired quality, ten, fourteen, or any karat, as the entire outer shell is of precious metal, and does not become decreased in its value soldering auxiliary plates, and the like. Also, by the improvements described the cost of manufacture is reduced, and at the same time a better article in every respect is obtained.

l have shown an embodiment of my invention, but changes may be made therein without departing from the spirit of the invention, as defined in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. An improved pocket knife, comprising inner' supporting plates of base metal, having a contour corresponding to the finished design of the knife, blades pivoted between said plates, a spring member supported between said plates and having its outer surface extending beyond the lower edge of the said plates and forming part of the finished surface of the knife, and controlling the action of the said blades, outer plates of rela-tively thin precious metal previously shaped to finished design secured to said inner plates, the outer surface of the said inner plates and the inner surface of the said outer plates being snugly contiguous to each other at all points, the said outer plates having their edges extending over the edges of the said inner plates to the inner sides of the said inner plates, thereby entirely covering the outer surface of the said inner plates of base metal, and abutting at the lower edge of the said knife the said extending l portion of the said spring member, and lying flush therewith to form a smooth outer surface.

2. An improved pocket knife, comprising inner supporting plates of base metal, having a contour corresponding to the finished design of the knife, and having an ornamental design incised thereon, blades pivoted between said plates, a spring member supported between said plates and having its outer surface extending beyond the lower edge of the said plates and forming part of the finished surface of the knife, and controlling the action of the said blades, outer plates of relatively thin precious metal previously shaped to finished design secured to said inner plates, and haring an ornamental design embossed therein registering with the ornamental design of the said inner plates, the outer surface of the said inner plates and the inner surface of the said outer plates being snugly contiguous to each other at all points, the said outer plates h a ving their edges extending over the edges of the said inner plates to the inner sides of the said inner' plates, thereby entirely covering the outer surface of the said inner plates of base metal, and abutting at the lower edge of the said knife the said extending portion of the said spring member, and Aying flush therewith to form a smooth outer surface.

in testimony that i claim the foregoing as my invention i have signed my name in presence of two subscribing witnesses.
