IMPROVEMENT lN POCKET-CUTLERV.
Specification forming part of Letters Patent No. 185,062, dated December 5,1876; application filed May 13, 1876.
lowing is a full, clear, and exact description of the saine, reference beinghadto the accompanying drawing, which forms part of this specification.
This invention consists in a novel construction of pocket-cutlery, whereby the inner scale, whichis cast in one piece with the bolster and `the tip, has also cast on its outer sides or surfaces ribs, which not merelyl serve to hold the covering-scale in position on the inner scale, but also materially contribute to stiffen the latter. The invention also consists in a cast inner scale, with the spring-s pivot cast in one' piece with it, and having the blade-pivot embeddedin said casting.
A pocket-knife constructed in accordance with this invention has its blade or blades and spring secured in their respective positions, and the covering-scale secured in its position during and by the operation of cast ing the inner scale with its attached bolster and tip.
Said invention essentially differs from that described in Letters Patent issued to me March l2, 1873, in which the inner scale was of perforated sheet metal, and a filling of inolten metal was used to unite the covering-scale with the inner scale, also to form and unite the bolster with the latter, and in which the blade and spring pivots were separately and subsequently inserted through the scale or scales.
Figure l represents a back view. of a singleblade pocket-knife constructed in accordance with myinvention, showing the blade extended or open; Fig. 2, a transverse section of the same on the line w and Fig. 3a further transverse section on the line y y. Fig. 4 is a longitudinal section ofthe knife in a plane at right angles to Fig. 1, showing a modilied construction for uniting the covering-scale with the inner one; and Fig. 5, a transverse section of the same on the line z z.
The inner scale a is cast in a mold, and may be of White or other suitable metal, and has stiftening-ribs b b cast at the same time along its outer sides or surfaces, also the-bolster o and tip d. The stiffening-ribs b b have two functions or uses-that is to say, they not only serve to strengthen the cast inner scale a, but also hold the covering-scale sections f f in 'position by entering longitudinal grooves e e in the inner faces thereof. These grooves may either be of a dovetailed construction, as in my former patent hereinbefore referred to, and as shown in Figs. l and 2, whereby the ribs b b, of corresponding configuration, serve to lock as well as to hold the covering-scale or scale-sections in position, or the grooves e e may be constructed of a form which simplyv Y serves to hold the covering-scale in position transversely of its width, (the ribs b b being of corresponding configuration,) and riveting projections g g be cast on the ribs, and, by entering correspondingly-shaped holes in the covering-scale, serving, in conjunction with the ribs, to lock or secure the coveringscale sections in all directions, as clearly shown in Figs. '4 and 5 of the drawing. grooves ee may either extend throughout the length of the scales, or only partially throughout their length, or be of a broken or interrupted construction throughout their length. Furthermore, the cast inner scale a. has formed at the same time with it, in the process of casting, the pivot n of the spring k, which acts on the back ofthe blade h, likewise the back support for the spring at the tip d, said springk being suitably inserted in the Inold in which the inner scale a is cast. Said inner scale has also the blade-pivot Z loosely embedded in and projecting through it and into the bolster c, with rivet-heads or swelled ends, as shown in Figs. l, 3, and 4, by running the metal in the mold in the formation of the inner scale a and bolster c round said pivot l, which, to-
gether with the blade h, is suitably inserted in the mold for the purpose.
In this Way the entire knife may be made or finished in the mold with the exception of exvternally dressing the covering-scaleff-that is to say, its inner scale, covering-scale or scale-sections, bolster, tip, blade, and spring all be secured in their respective relative' or working positions by a single casting, with or without the rivet or pivot heads visible on the The ribs b b and I exterior of the covering-scale. By such improvement. I am enabled to produce pocketontlery atJ a much reduced cost and of a superior description.
I claiml. The inner scale a, cast in one piece with the bolster c and tip d, and with ribs b b along its outer sides or surfaces, for the purpose of stiiningthe cast inner scale, and of uniting the latter with the covering-scale sections f f, substantiallyas specified. u
2. The inner scale a, with the knife-bolster and tip, cast not only in one piece with each other, but also with the pivot n of the assembled blade-spring, essentially as described.
3. The inner scale a, with the bolster and tip,oast in 011e piece with each other7 and with the pivot: 'n of the blade-spring, in combination with the independently-embed(led blade-pivot; l, and theassembled blade h and spring k, substautially as specified.
