PHILIP T. CHAMPLIN AND FRANCIS J. B. CHAMPLIN, 01 LITTLE VALLEY, NEW" YORK KNIFE Application filed June 30,

This invention relates to cutlery and more particularly to a knife and one object of the invention is to provide a knife having a handle of an improved construction which is '5 very attractive in appearance and very strongly made.

Another object of the invention is LO so form the handle that when the knife is in use it may be very easily held in a persons hand as it will be free from sharp corners and to also so form the handle that a clip may be applied to it and thereby permit the knife to be easily carried in a coat pocket.

Another object of the invention is to pro vide a knife having its handle so formed that it will closely resemble pens and pencils which are sold as a set thereby permitting a knife of the improved construction to be sold as a third article in the set.

Another object of the invention is to so form the handle that when manufacturing, the body portion of the handle and the tiller or blade carrying frame may be very easily assembled and the blade carrying frame very firmly held in a pocket formed in the body portion.

The inventlon. is illustrated in the accompanying drawings wherein:

Figure 1 is a side elevation of the im- 30 proved knife,

Figure 2 is a view of the knife looking at the upper portion of Figure 1,

Figure 3 is a longitudinal sectional view through the knife taken along the line 33 of Figure 2,

Figure 4 is an enlarged transverse sectional view through the knife taken along the line of Figure 3, and

Figure 5 is a perspective view of the blade carrying frame.

The handle of the knife has a pre-formed body 1 preferably of a composition resembling mother of pearl although any other suitable material may be employed if desired. This body is preferably circular in cross section as shown in Figure l and at one end tapers to a point in order to add to the attractive appearance of the knife and also to pro- Vlllt! a conical rubbing surface which may be til) 1931.

used to advantage when making erasures with the knife.

A pocket 2 is formed longitudinally in the knife and by referring to Figures 2 and?) it will be seen that this pocket is open along one side and at one end terminates in spaced re lation to the tapering end of the body. It should also be noted that at the open end of the pocket the body is cut away externally thereby forming a rcducetbend portion 3 0 having a circimiferential shoulder a at its inner end.

A. clip 5 of the type used upon fountain pens extends longitudinally of the handle and has its outer end portion firmly secured by pins or rivets 6 which extend transverse ly through the body. Therefore the knife maybe placed in an upright position in a coat pocket and secured in the same manner in which fountain pens and fancy pencils are held when placed. in a pocket. l

The filler or blade carrying frame which is shown'in Figure 5 has side plates 7 which are preferably formed of stiff metal and at one end are joined by a band or ferrule 8 which fits over the reduced portion 3 of the knife handle. The springs 9 for the blades 10 extend longitudinally of the frame between the side plates 7 thereof and between 0 the sprin is located a partition 11. formed of sheet metal which is preferably thinner than the metal from which the side plates are formed. A pivot pin 12 for the blades extends through the heels of theblades in the usual manner as shown in Figure 3 and has its ends firmly engaged in openings 13 formed in the side plates 7 within the band 8. The usual pin 14 for the springs is provided intermediate their ends and has its ends firmly secured in openings 15 formed in the side plates. The pin 16 which passes through the springs and through the openings 17 formed near the inner ends of the side plates is of greater length than the pins 12 and 14 as this pin is to extend transversely through the body and serve as securing means to pre vent the filler or blade carrying frame from moving out of its proper relation to the body portion of the handle. This pin 16 is not inserted until the blade carrying frame has been fitted into the pocket 2.

\Vhen manufacturing the improved knife, the body portion 1 of the handle is formed of mother of pearl, celluloid or any other suitable material which will be attractive in appearanceand will blend with pens and pencils now manufactured and sold-as a set. The blades and springs together with the partition 11 are set in place between the side plates 7 where they are secured by-the pins 12 and 14 and the filler or blade carrying frame is then fitted into the pocket 2 and the filler and body portion of the handle moved longitudinally of each other until the reduced end portion 3 of the body enters the band or bolster 8. The reduced end of the body projects slightly from the outer end of the band as shown in Figures 1 and 2 and is beveled in order to provide a good finish for this end of the knife. After the filler or blade carrying frame is in place, the pin or rivet 16 is inserted and its ends upset in order to retain it in place. Since this pin extends transversely through the body of the handle, the filler will be very firmly secured and prevented from moving longitudinally of the handle, Therefore it cannot move out of its proper position relative to the body portion of the handle and the knife will have a very firm construction.

What is claimed: 7

1. A knife comprising a pre-formed integral handle having one end thereof-tapered and one side solid and formed with a longitudinally extending pocket open alongthe other side and at one end of said body, a frame in said pocket, a blade in said frame movable from a closed position outwardly through the open sideof the pocket to an opened position in which it extends longitudinally of the handle from the open end of the pocket, and means to retain the frame in place within the pocket.

2. A knife comprising a pre-formed integral handle having one side thereof solid and one end reduced, said handle being formed with a longitudinally extending pocket open along the other side of the handle and at the reduced end thereof, a frame in said pocket, a blade in said frame movable from a closed position outwardly through the open side of the pocket to an opened position, and a band 7 carried by the, outer end of said frame and fitting snugly about the reduced end of the handle. 7

3. A knife comprising a pre-formed integral handle having one end solid and formed with a longitudinally extending pocket open along the other'side and at one end of said handle, a, frame in said pocket, a blade in said frame movable from a closed position outwardly through the open side of the pocket toan opened position, the end porbody formed with a longitudinally-extending pocket open along one side and at one end, a frame in said pocket having side plates fitting against side walls of the pocket, a spring between the plates, a blade between the plates having its heel engaged by said spring, pins extending through the frame to retain the spring in ,place and pivotally mount the blade, and a band carried by the outer end portions of the side plates of the frame and fitting snugly about the body to reinforce the body and prevent the frame from moving transversely of the body through the open side of the pocket. i

5. A knife comprising a handle having a body formed with a longitudinally extending pocket open along one side and at one end, a frame in said pocket having side plates fitting against side walls of the pocket, a spring between the plates, a blade between the plates having its heel engaged by said spring,pins extending through the frame to retain the spring in place and pivotally mount the blade, one pin having its end portions extending through the body to prevent longitudinal movement of the frame in the pocket, the end portion of the body aboutthe open end of the pocket being reduced externally to form a reduced portion having a circum ferentially extending shoulder at its inner end, and a band carried by the outer end portions of the side plates of the frame and fitting snugly about the reduced end portion of the'body against said shoulder and serving to reinforce the body and prevent the frame from moving transversely of the body through the open side of the pocket.

In testimony whereof we affix our signatures.
