April 27, 1954 SCHIERGHOFER 2,676,405 CUTTER, PARTICULARLY ADAPTED FOR THE USE IN CUTTING WALL COVERINGS Filed July 3, 1951 INVENTOR. FRED SCH/EEGHUFBE ATTORNEY Patented Apr. 27, 1954 CUTTER, PARTICULARLY ADAPTED FOR THE USE IN CUTTING WALL COVERIN GS Fred Schierghofer, Tuckahoe, N. Y. Application July 3, 1951, Serial No. 235,049
3 Claims. (01. 30%293) Th present invention relates generally to cutting devices, and is particularly directed to wallpaper cutters or trimmers of the kind employin a razor blade or other similar cutting element;
When wall-paper or other sheet covering is aflixedzto a wall it is necessary to trim the paper or sheet covering along the edges adjacent to the wood work, such as, door frames, window frames, base boards and ceiling mouldings, as well as in corners where Walls are joined. In trimming wall-paper as above, .it is desirable that the cutt ng blade be prevented from cutting into the underlying wall to thereby protect the wall from damage, and also to increase the period during which the cuttin blade retains its sharpness. If penetration of the wall by the cutting blade is to be avoided, the paper, in the immediate area being cut, must be spaced from the wall so that the blade may cut through the paper alone. In trimming the edges of wall paper adjacent to wood-work of various kinds or along the corners where other walls meet the wall to which the paper is being applied, it is desirable that the adjacent wood-work or meeting wall be used as a guide for the cutting blade without contacting the'latter, which contact would dull the cutting edge. Finally, it is desirable that provision be made for adjusting the position of the cutting blade relative to the guide member so that the latter may be engaged with th adjacent woodwork or meeting wall at either side, above or below the cutting blade.
It is therefore an object of the present inven-: tion to provide a wall-paper cutting or trimming device for holding a cutting blade in a manner to trim the'edges of wall-paper or the like without penetrating or damaging the underlying wall surface, and which is guided by contact of the device with the adjacent wood-work or meeting wall, with the blade itself being protected against dulling contact with the guiding wood-work or meeting wall.
Another object is to provide a wall-paper cut ting or trimming device in whichthe cutting blade is supported relative to the wall by a laterally rounded guide member so that the paper may stand away from the'underlying wall in the immediate area being cut, and in whichthe guide member is adjustable relative to the cutting blade so that the latter may be arranged, close to the wood-work or meeting wall engaged by either side of therounded guide member.
fFinally, an object of this invention is to providea wall-paper cutting or trimming device of the character described above which is simple and sturdyinconstructio iii) With these and other objects, features and ad-' vantages which will appear as the description proceeds in view, the present invention consists in the combination, arrangement and details of construction of the several parts of the device hereinafter described and illustrated in the accomp'anying drawing, and then more particular- 1y defined in the appended claims.

Fig. '7 is a front elevational view, similar to Fig. 6,; but showing the guide member in the adjustediposition of Fig. 5 for cutting wall-paper alongja length of wood-work or a meeting wall, shown'in section, at the side of the device opposit to'the location of the wood-work or meeting wall in Fig. 6; and
Fig. 8 is a side elevational view, looking in the direction of the arrows 8-8 of Fig. 6, and showing the cutting device in cutting position.
Referring to the drawing in detail, and initially to Figs. 1 to 4 thereof, a cutting device, embodying the present invention, is there shown and generally indicated by th reference numeral 0 The cutting device I 0 includes a suitably shaped handle H having a cutting-blade holder 12 formed to removably hold a cutting-blade l3 which is preferably in the form of a single-edged razor blade. The holder 12 forms a channel opening along the bottom edge l4 and at the end adjacent the handle II to slidably receive the spine or head of the razor blade I3 with the cutting edge portion of the latter extending through the bottom edge I 4, The holder I 2 is formed so that the edge I 4 thereof is ansularly related to -be swung as in Figs.
the longitudinal axis of the handle II to thereby permit insertion and removal of the cutting blade through the end of the holder [2 adjacent the handle without interference from the latter. The angular relationship of the holder and handle further permits cutting engagement of the blade is with wall-paper while positioning the handle remote from the wall to which the paper is applied (Fig. 8) so that the handle may be conveniently grasped.
The cutting device iii according to this invention further includes an assembly for supporting the device relative to the wall so that the latter is not penetrated during the cutting or trimming of the wall-paper, and for guiding the cutting device along an adjacent length of woodwork or a meeting wall disposed at either side of the cutting blade. This assembly comprises a circular bushing l i i from which the blade holder i2 extends. The bushing is is formed with a pair of axially spaced apart, radial flanges is and ll defining an outwardly opening, annular channel therebetween. A support and guide member It is swingably mounted in the channel defined between the flanges it and i'l, and includes a split ring-like part is having legs 28 and 2| extending from the ends thereof and engaging slidably between the flanges it and il The legs 2i! and 24 are bowed outwardly intermediate their lengths (Fig. 2) to conform to the circumferential configuration of the annular channel between thefianges 2E and ll so that the support and guide member 58 may 5, 6 and 7 relative to the handie 9 i and blade holder l2 but is restrained from radial displacement relative to the latter by the engagement of the bowed parts of the legs 28 and. M in the annular channel of the bushing 15. A locking link 22 is formed with loops on its opposite ends which extend around the iree'end portions of the legs ill and El to prevent spreading apart of the latter and disengagement of the member is from the bushing P5.
In order to limit the swinging movement of the support and guide member i8 relative to the blade holder 82, the flanges it and I1 are pinched together at diametrically opposed locations, as at 23 and 2d (Figs. 3 and 4), to restrict the channel formed between the flanges. Thus, when themember i8 is swung in one direction, as in Figs. 5 and '7, the leg 2% will be stopped by the restriction 2t and the leg it will be stopped by the restriction 2-2. Conversely, when the member [8 is swung in the opposite direction, as in Fig. 6, leg 2! is stopped by the restriction 23 and leg 26 is stopped by the restriction 2A.
As is apparent from Figs. 1 and 8, the ringlike part 19 of the member it lies in a plane which is angularly disposed relative to the legs 20 and 2% and the part is is dimensioned so that it engages the wall-paper being cut, and is normal thereto, when the forward end of the cutting blade lt engages'the paper (Fig. 8).
Referring to Figs. 6, '2 and 8, an appreciation of the manner of using the above described device, and its advantages, may be obtained. In Fig. 6, the wall-paper has been applied to a wall 26, and it is desired to trim the paper along a length of wood-work or a meeting wall 21 which is to the right of the edge being trimmed as shown. The support and guide member I8 is positioned for cutting in that situation by swinging relative to the blade holder l2 in the direction awayirom the guiding wood-work or meeting wall 2'! "so that, with the ring-like part I9 engaging both 5 on the end of the handle 1 'tudinal axis of the latter, a cutting blade 4 the wall 26 and the wood-work or meeting wall 21, the cutting blade I3 is disposed close to the latter for trimming the paper 25 substantially in the corner.
The engagement of the ring-like part 19 with the paper on the wall 26 supports the cutting blade relative to the latter so that the wall will not be penetrated or damagedduring the trimming' of the paper, whilethe simultaneous engagement of the ring-like part I9 with the woodwork or meeting wall 2? causes the latter to guide the blade during the cutting stroke. The ringlike configuration of part 19 permits engagement thereof with the wall 26 and the meeting wall 21 without forcing the paper in the immediate area being out against the wall. Thus, the cutting blade may cut through the paper without dulling contact with the underlying wall or the guiding wood-work or meeting wall (Fig. 8).
When the guiding wood-work or meeting wall is disposed at the other side of the cutting device, as in Fig. 7, the support and guide member is again rocked relative to the blade holder, this time toward the right as viewed in Fig. 7, so that the cutting blade is once again positioned to trim the edge of the wall paper 25' along a line in the corner formed by the'wall 26 and the guiding wood-work or meeting wall 21'.
From the above description it can be seen that the present invention provides a cutting device which may be used in trimming the edges of wallpaper and the like along the top, bottom or either side thereof.
While I have illustrated and described in detail a preferred embodiment of my invention, it
is to be understood that I do not desire to be limited to the precise embodiment and that many changes and modifications, obvious to one skilled in the art, .may be made therein without departingfrom the spirit and scope of the invention as defined in the appended claims.
