Application filed February6,1905. Serial No. 244,372.
To all whom it may concern:
Be it known that I, GEORGE M. TILDEN, a citizen of the United States, residing at Detroit, county of Wayne, State of Michi an, have invented a certain new and useful%mprovement in Knives and Analogous Articles, of which the following is a specification, reference being had to the accompanyin drawings, which form a part of this speci cation.
My invention has for its object certain new and useful improvements in knives and analogous articles of manufacture; and it consists 0 the construction, combination, and arrangement .of devices hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a view in side elevation, illustrating features of my invention. Fig. 2 is a view in plan looking at the top of the knife shown in Fig. 1. Fig. 3 is a View in crosssection on the line 3 3, Fig. 1. Fig. 4 is a view in side elevation, showing one of the shields removed and parts insection. Fig. 5 is a view in side elevation, showing a modification of the invention. Fig. 6 is'a view in cross-section on the line 6 6, Fig. 5. Fig. 7 is a view in cross section, illustrating another modification of the invention. Fig.8 is adetail view of the locking-cam. Fig. 9 illustrates the locking-cam in'position' to disengage the blade,-a nd Fig. 10'shows the locking-cam in position to lock the blade in position. 11 is a fragmentary view showing the shield in section.
My invention is more particularly designed to provide an improved slicing-knife, although I do not limit myself solely there to, inasmuch as features of the invention are adapted also for other kinds of knives, cleavers, and analogous articles of manufacture.
As pertaining to a slicing-knife my invention has for its chief feature to construct the blade from thin rolled steel and to give to the blade proper rigidity and firmness by means of one or more independent shields secured thereto at ,the upper edge of the blade, the shields being extended to form a portion of the rigid handle projecting longitudinally of the blade, the blade also being preferably extended to form a part of the handle, although the blade might be terminated at the point of the attachmentof the handle to the extended ends of the shields without departing from my invention.
Another feature of my invention, although I do not limit myself solely thereto,
' from the shields and handle.
. per portion of the blade and may be is to provide a knife having a detachable blade and means to secure the blade in osition, and whereby the blade may be readi disengaged lVfy invention, however, in certain of its features is adapted also to blades having a rigid attachment to the shields.
In the drawings, a represents a knife-blade as above described. .As applied to a knife it is preferably formed of thin rolled steel. It wi l readily be seen that the blades so formed may be readily struck out by a suitable die from a sheet of thin rolled steel-as, for example, from a sheet twentyfive one-thousandths of an inch in thickness. The sheet of rolled steel may be made of any desired percentage ofcarbon wanted, and the sheet of rolled steel may be thus readily suitably tempered before the blades are struck out therefrom, so that the blades will not require to be tempered, althou h I do not limit myself solely to the avoi ance of retem ering the blades. It will, however, be readily seen that blades so struck out from sheets ofrolled steel and suitably tempered Will have a uni form temper and being made thin may be readily sharpened'as ma be required, one feature of my invention eing to make the blades so thin that they may be very readily sharpened and much more readilykept sharpened than blades as ordinarily formed. s blades have heretofore beenconstructed they have been found to be of different tempers, and it has been a hard matter to get the blade of even temper throughout, which difficulty, however, may be entirel overcome by constructin the blades as a ove described.
A shie d is indicated at b. The shields are located, preferably, on both sides of the upformed of separate and independent strips of suitable metal. Instead, however, of the shields b I) being formed of two independent strips of metal they might be forms of oneintegral piece bent or grooved, as indicated more particularly in Fig.7, to extend over the u edge of the blade and downward towar edge a desired distance. The shield maybe made of any suitable metal and mi ht have a different temper from that of the b ade, if de sired. The shield may be made in various ways within the scope of my invention and may be secured to the blade in various ways, as by rivets, brazing, or otherwise. The rear ends of the shields are shown extended to per the IIO form a part of the handle 0, other parts of the handle being made of any desired material. As shown, the rear extremities of the shields and blade are embraced between side portions land 2 of the handle. In Figs. 4 and 5 portions of the handle are omitted. The rear extremities of the blades and shields extend longitudinally of the blade and are readily secured with other features of the handle, as by means of rivets or screws (1. When the shields are made in the form shown in Fi 7, I prefer to recess the upper portion of the lade. as indicated at c, Fig. 1 1, to receive the upper portion of the shields, so that the upper surface of the shield and the forward end of the blade will be flush.
In Figs. 1, 2, 3, and 4 I have shown a back strip (indicated at f) located above a portion of the upper edge of, the blade and between the two shields, the shields being riveted. to-
gether through said back piece or strip, as indicated at g. I This back strip f, if employed,
may have a spring temper and is (preferably employed where the blade is ma detachable. Where the back strip is employed, the forward end thereof has a tenon indicated at h) to enter a corresponding sock t 'i in the upper edge of the blade to hold the forward end of the blade in en agement therewith.
The blade and shields, toward the rear end thereof, when the blade is made detachable are provided with a suitable locking device to hold" the knife in engagement with the shields. I do not limit myself solely to any particular locking device. That shown consists of a cam, (shownin detail in Fig. 8 at y',) said cam being shown provided with a roove k and with an operating knob or han e Z to rotate the dam. The blade in this instance together, as indicate is provided adjacent to the cam with a shoulder, (indicated at m,) under which the bod of the cam adjacent to the groove is move as shown in Fig. 10, to hold the blade in locked enga ement with the shields, only one of the shiel s-being shown in Figs. 9 and 10. By rotating the cam into position shown in Fig. 9 it is evident that the body of the cam ad acent to the groove kis moved out from in under the shoulder m, permitting the disengagement of the blade from the shields, the blade being formed with an opening n to permit the blade being moved past the cam.
In Fi 6 the back strip f is omitted, and the shie ds have; their upper edges flush with the upper ed e of the knife-blade, the blade and the shie ds being permanently riveted at p. I prefer also where the blade is made detachable to construct its rear end with a recess (indicated at vg) to receive one of the rivets or screws d.
This will prevent a forward movement of the blade liable to cause its disengagement with the tenon h of the back strip.
The shields might have a spring tension, if desired, upon the surface of the blade and might be soldered in place also, if desired, when the blade is to be permanently engaged therewith. By making the shields to have a spring tensionupon the blade a tight fit w1ll be secured. What I claim as my invention is a 1. A slicing-knife or analogous article of manufacture comprising a thin blade, a shield to stiffen the blade located on the surface of the blade at the upper edge thereof, .and a handle extending longitudinally of the blade, the pointof the. blade extending forward of the shield and the cutting edge of the blade projectingbelow the shield sufficient to give clearance to the blade in slicing.
2. A slicing-knife or analogous article of manufacture comprisin a blade formed of thin steel, a shield to stien the blade located on the surface of the blade at the u per edge thereof, and a handle extending ongitudinally of the blade, said shield formed with an integral extension at the rear end thereof forming a part of the handle, the point of the blade extending forward of the shield and the cutting edge of the blade projecting below the shield sufficient to give clearance to the blade in slicing.
