A ril 28, 1931- E. w. ERICSSON KNIFE Filed Jan. 21, 1930 INVENTOR. 516 M [TltSSan A TTORNE Patented Apr. 28, 1931 Application filed January 21, 1930. ,serial No. 422,251.

This invention relates to knives, erasers and the llke; and the ob ect of the'lnvention 1s to-pro-vide a knife of the class specified comprising a handle member consisting of relatively movable 'parts'and a blade member adapted to be arranged between the separate parts of the handle member and retained in different positions with-respect thereto as well as being readily detachable therefrom 19 whereby new blade members may be substituted for old or worn out blades; a further object being to provide means for pivotally coupling the separate parts of the handle member at one end thereof to permit the separation of said parts with means adjacent the other end of said parts for clamping the.

same together and for retaining the blade in connection therewith; a further object being to so fashion the separate parts of the handle member at the blade end of the knife as to conform with the contour of the shank of the blade in the several positions thereof to key the same against movement independently of the first named securing means; and with these and other objects in view, the invention consists of the knife of the class and for the purpose specified which is simple in construction, eflicient in use, and which is constructed as hereinafter described and claimed.

The invention isfully disclosed in the fol lowing specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which:

Fig. 1 is a side view of a knife made according to my invention showing the blade in position for use.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is a section on the line 33 of Fig. 1. i p

Fig. 4 is a side view of the opposite side of the handle of the knife fromthat' shown in Fig. 1, and illustrating the blade in inoperative position; and, i

Fig. 5 is a section on the line 55 of Fig. 4. i v In the drawing, I have shown one construction of knife for carrying my invention into eflect, and inthe several figures, lOi-epresentsthe handle member and 11 the blade. The handle member 10 in the construction shown is fashioned from two sheet metal parts12 and 13, the handle end 14 of which is concave convex in cross sectional form so that the marginal edges will abut as indicated at 15, note'Fig.,2 of the drawing, and

the parts 12 and 13 are pivoted together as seen at 16'at the end portion 1 1 whereas the jaw ends 17of the parts 12and 13 are. relatively flatexcept that the part 12 has arec'ess on its inner surface formed by stamping the material'o'f said partoutwardly in' accord- 5 ance with'the contour see'nat 18 in Fig. .1 of the draw ng so as to provlde a recess 19 of an outline corresponding to that of the shank 'end'20 of the blade "11. In like manner, the

jaw end of the part 13 is pressed outwardly in the manner indicated at 21, note Fig. 4.

to form a recess to receive the shank of the blade 11 when saidblade is support-ed in the positionindicated in Fig. 4 of. the drawing with the cutting end 22 arranged within and between the-parts 12*and 13.

.The outwardlypressed portions 18 and 21 servers key. the blade 11 against movement relatively to thehandle'member "10orthe separate parts thereof "when the blade is in the position'sliown in Figs. land 4, andthe aw ends 17 of the parts 12and 13 are clamped together by 'ascr ew 23 in threaded engagement with the part 13, and the milled head 24. of which operates to .move the part 12 toward the part 13 to securely'clamp the blade 11 in position, it being understoodthat the blade 11 has'an aperture through which the screw 23 passes asiclearly seen in Fig. 20f the drawin I Y the use ofthe device, it will be 'understood that the blade 11 isplaced within; and between the jaw end 17 of'the parts 12 and 13 in the manner shown in Figs. 1 and 2 of the drawing andthe screwj23' moved into position to securely clamp thefblade'within and between the adjacent faces of said parts, and

the knife is nowin position for use. At this time, it will beunderstood that the blade end of the knife "may be of any desiredconftour or size, the handle member or the parts thereof beingv fashioned to correspond with that of the blade, and when it is desired to discontinue the use of the knife, the screw 23 is loosened sufliciently to allow the blade to be swung into the position shown in Fig. 4: with the blade end 22 within and between the parts 12 and 13 and the boundaries thereof, after which the screwis again tightened to retain said blade against displacement, and in this position the blade may be carried about.

Whenever desired, a new blade or a diff ferent type of blade may be coupled with the handle member by removing the screw and v by swinging the handle members on their pivot 16. The latter is not absolutely neces jsary as the openingin the blade may extend through one wall thereof to form a notch type aperture as iscustomary inv other types of tools of this class. o

It will also be understood that while I have described my invention as pertaining to knives, scrapers andthe like, it will be understood that any kind or class of blade may be mounted in connection with the handle member such for example as chisels, saws and ing in jaws in connection with which a blade is adapted to be movably supported, a screw passed through said jaws and blade for clamping the blade in different positions of] adjustment within and between said jaws, one jaw having an outwardly pressed portion of a contour corresponding to that of the shank of said blade to retain the blade against movement when in projected position, and the other jaw member having an outwardly pressed portion conforming with the contour of a part of the shank of the blade to retain the blade against movement with respect to the like, the distinctive feature of my invention being to providea cheap and yet strong and durable handle member so constructed as tolpermit the mounting of tools of various kinds'and classes in connection thereof, all having a shank of common contour facilitating the mounting of the tool in connection with the handle member. Various changes in and modifications of the construction herein shown and described may be made within the scope of the appended claims without de parting fromethe spirit of my invention or sacrificing its advantages.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is Q i I V 1. A knifeiof the class described comprising two. elongated,fsheetmetal handle mem bers pivotally coupled together at one end to permit separation of said handle members in the plane of the'abuttin'g faces thereof, the

other ends of the handle membersterminating in jaws in connection with which a blade is adapted to bemovably supported, a screw passed through 'said'jaws and blade for and one jaw havingxan outwardly pressed portion projecting beyond the outer face of the jaw and of a contour corresponding to that of the shank of said blade to retain the bladeagainstmovement when inprojected ther ends of th handle membersterminatclamping the blade in different-positions of o adjustment within and between saidjaws,
