SPECIFICATION forming part of Letters Patent No. 294,471, dated March 4, 1884.

Application filed July 12, 1883. (ModeL) To aid whom it may concern Be it known that I, ORIsON HUFF, of Lyman, in the county of York and State of Maine, have invented a new and Improved Pocket-Knife,

of which the following is a full, clear,- and'exin which similar letters of reference indicate corresponding parts in all the figures- Figure 1 is a side elevation of my new and improved pocket-knife as it appears when closed. Fig. 2 is a sectional plan view of the same, taken on the line so xof Fig. 1. Fig. 3.

is a broken perspective view of the blade and lower section of the handle and the operative parts connected thereto removed from the upper sectionof the handle, and Fig. 4 is a side elevation of the knife as it appears when open.

The upper section, a, of the handle of the knife is formed or provided with the collar 12 at its forward end. This collar is suitably recessed at one side, as shown at g, to receive the cap 0, which is pivoted in the recess, and formed with the stud d for entering the socket 6, made in the shank of the blade f, for locking the blade in position for use, and the cap is acted upon by the spring g, placed in the said recess,-for pressing itforwardto cause the stud d to enter the Socket 6, and also to cause the cap toclose the end of the section a when the knife is closed. The bladef is of ordinary construction, except that it is formed with thesaid formed in it, adapting the blade to be held by and to slide upon the bevel-edged bar or plate i, that is pivoted in the lower section, j, of the handle, for preventing the sharp edge of the blade from running in contact with the said section while the blade is being opened and closed. The lower section, j, of the handle is made to fit within the upper section, a, and is provided with the pin is at its rear end, on which the coiled springl is placed for forcing the sections of the handle apart at their rear ends; and this section j is also provided with the pivoted and notched locking-plate m, that is pressed rearward at its notched end by the action of the springo upon its opposite end, for causing it to engage (when the sectionsare pressed together by the hand of the user against the pressure of the spring Z) with the projection 10, formed in the section a, for holding the sections of the handle together-the position they will occupy both when the blade is in position for use, and also-when it is closed'within the handle.

Attached to the inner end of the lockingplate m is the rod g, which reaches forward near to theforward end of the section j, and passes through the section to the outside, where it is enlarged to form a thumb-piece, by which it may be easily moved longitudinally backward for operating the plate m, for unlocking the sections of the handle for opening and closing the knife. The forward end of the section j, where it passes within the collar 1), is formed with the projection T, which is perforated to engage with the pin 8, fixed in and projecting from collar 12 of section a, for pivoting the sec tions a j together, and for constituting a fulcrum, so that when the sections of the handle are squeezed together when the knife is open they will grasp the shank of the blade and hold it firm.

To open the knife, hold it loosely in the right hand and with thethumb press backward upon the projecting end of the rod g. This will detach the notched plate m from the projection 19 and permit the spring Z to throw the two parts of the handle open a short distance. thumb will now-be pressed upon the rear edge of the cap 0, which will turn the cap on its be pressed together by a slight squeeze of .the

hand, which will cause the sections to grasp the shank of the blade and cause the plate m to engage with projections 1), and thus lock the sections in closed position, thus holding the blade with suffieient firmness for use. To close the knife, the sections aj of the handle will first be unlocked by pressing backward upon the rod q. The cap 0 will then be operated by the thumb to lift the stud (I out of socket c, and then by turning the point of the blade upward it will drop of its own accord back into the handle. The sections of the handle will then be squeezed together and locked, when the knife is ready for the pocket. The sliding outward and inward movement of the blade f, it will be seen, is upon the rod or plate i, which holds the sharp edge of the blade, so that it will not be dulled by moving against any part of the handle.

I do not confine myself to the use of the l1an-.

dle with a knife-blade, as other tools-such as a screw-driver, flat file, fine saw, chisel, gage, or similar tool-might be used with it, and, instead of using the pin (1 forholding the blade from back ward movement when in position for use, a'ratchet device might be used for that purpose, either alone or in connection with the stud (7.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A knife-handle formed of two hollow sections, aj, the upper one having collar I), with pin 8 and projections 19, and the lower one having rear. pin, 7:, surrounded by a spiral spring, a pivoted spring-pressed and notched locking-plate, m, an operating-rod, q, and a perforated projection, r, as shown and described.

2. In a hollow knifehandle, the front collar, 1), carrying a pivoted spring-pressed cap, 0, in its recess g, and a stud, d, on the cap 0, in combination with a loose blade, f, having a socket, c, in its shank, whereby the blade may be securely held inside or outside the handle, as described.

3. A hollow handle having the bevel-edged plate 1, pivoted at its front end, in combination with a loose blade, f, having the dovetailed groove h, whereby the blade may slide in or out of the handle without striking its edge, as described.
