D. W. BRYANT. POCKET KNIFE. APILIUATION FILED MAY 14, 1910.

DALTON W. BRYANT, 0F CAR-BONDAIE, PENNSYLVANIA.

POCKET-KNIFE.

Specicaton of Letters Patent.

Patented Nov. S, 1910.

Application filed May 14, 1910. Serial No. 561,358.

To all whom it may concern.'

Be it known that I, DALTON W. BRYANT, a citizen of the United States, residing at Carbondale, in the county of Lackawanna and State of Pennsylvania, have invented new and useful Improvement-s in Pocket- Knives, of which the following is a specification.

This invention relates to pocket knives and more particularly to the construction of the handle into which the blade or blades close.

The invention has for one of its objects to provide an improved handle of that type in which the parts are detachably connected together so that the blades can be readily taken out and new ones substituted when desired.

Another object of the invention is to improve and simplify the construction of knife handles so as to be comparatively easy and inexpensive to manufacture, of durable and substantial design, and composed of comparatively few parts.

With these objects in view and others as will appear as the description proceeds, the invention comprises the various novel features of construction and arrangement of parts which'will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention :-Figure 1 is aside view of the knife. Fig. 2 is a plan view thereof. Fig. 3 is a detail sectional view of one end of the handle with the blades removed. Fig. t-is a detail perspective view of the parts at one end .of the handle with the exception of the blades and their springs, the said parts being separated in their proper relative positions.

Similar reference characters ar-e employed to designate corresponding parts throughout the several views.

In the present instance, I have selected to illustrate the invention as applied to a four blade knife, but it is to be understood that the number of blades can be varied as desired without affecting the principle of the invention.

Referring to the drawing, 1 designates the side members of the handle, which are fasn tened together by a rivet 2, which passes through the said members and the intervening part-s, These intervening parts consist of lining plates 3, a separating plate 4, and blade springs 5, the said plate extending the full length of the handle. At the ends of the side members l are cap pieces 6, which bear against the portions of the lining plates that project beyond the side members of the handle. These cap pieces are connected together in such a manner that they can be readily taken apart and put together. One piece is provided with a stud 7 that is round in cross-section and of such length as to extend to the opposite cap piece so that the stud forms a pivot for the blades 8. The said stud passing through openings 9 in the plates 3 and 4f. The stud is bored out longitudinally and is provided with screw threads 10 with which engages ascrew 11 that passes through an opening 12 in the opposite cap piece opposite from that on which the stud 7 is formed, and the head 13 of the screw is countersunk or set into a recess 14 in the cap piece. The inner edges of the cap pieces meet the end edges of the side members of the handle so that the cap pieces cannot turn, but to provide additional means for preventing turning, each cap piece has an inwardly extending projection 15 on its inner face that engages in an opening 16 in the adjacent lining plate 3, but this projection does not extend so far inwardly as to interfere with the knife blades.

With a construction of this character, it is a simple matter to take off a blade, as the cap pieces that carry the blade pivots can be detached simply by removing the screws 11, and the assembling of the parts is correspondingly easy.

From the foregoing description taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention relates, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes maybe made when desired as are within the scope of the claims.

What I claim as new and desire to secure by Letters Patent is 1. In a knife, the combination of handle members, lining plates having their ends eX- tending beyond the handle members and the projecting portions of the lining plates having separate openings', cap pieces at each end of the plates bearing against the projecting portions of the plates and each having projections engaging in one of the openings, one cap piece at each end having a screw receiving opening and the other cap piece at each end having a stud passing through the other openings of the lining plates, said studs being bored and tapped, screws passing through the screw receiving openings of the said cap pieces and engaging in the studs, and blades mounted pivotally on the studs.

2. In a knife, the combination of handle members, lining plates secured thereto and projecting beyond the ends of the members, a blade separating plate, said lining plates having alining openings, a cap piece bearing against one of t-he lining plates and having a stud extending through the openings of all the plates, a cap piece bearing against the other lining plate and having an opening, a screw passing through the opening and engaging in the stud,` projections on the inner faces of the cap pieces, said lining plates having apertures into which the said projections engage for preventing turning of the cap pieces, and blades disposed between the lining and separating plates, said blades having openings through which the stud projects to Jform a pivot for the blades.

In testimony whereof I atliX my signature in presence of two witnesses.

DALTON W. BRYANT.
