WILLIAM C. BRYANT, 0F COLUMBUS, OHIO.

Specification of Letters Iatent.

Application filed April 11, 1919. Serial No. 289,222.

To all whom it may concern:

Be it known that I, WILLIAM G. BRYANT, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Shears, of which This invention relates to shears, scissors and analogous severing instruments, and has particular reference to a simple and useful tool designed particularly for use by wall decorators in order that the latter may accurately and easily trim off and match the 'selvage or overlapping edges of wall canvas,

or other materials applied to a wall surface by means of an adhesive while the same are in position upon the wall.

In the art of wall decorating sheet canvas of certain widths and of a specially prepared nature is often placed over a plastered wall for the purpose of finishing the latter and so that cracks or crevices which invariably appear in plastered walls will be concealed from exterior view, this canvas surfacing also provides an excellent basis for the reception of the usual wall paper.

In hanging the canvas sheets the adjacent means of a rule or other straight edge. This tool, however, has been found to be defective in that considerable difliculty is encountered in accurately guiding the same during its cutting operations, its pointed extremity cutting into the plastered wall and thereby scarring the latter, its general awkwardness in use, and in the necessity of constantly resharpening the same.

Therefore, it is the object of the present invention to provide an instrument capable of being employed in the above capacity and which will be convenient to employ and manipulate, easy to guide and control during its cutting operations and having other features thereln particularly adapted to the class of work specified.

Another object of the invention resides in a pair of shears wherein is provided a stationary and a movable blade, which blades are pivotally united and are formed to terminate rearwardly in offset angularly disposed manipulating portions, and the forward end of the stationary blade being provided with an integral penetrating projection of peculiar configuration and utility, the same serving to facilitate the insertion of the shears into cutting relation with material to be severed and being also provided with an inserting point which is outside of the resting plane of the stationary blade, so that the point cannot catch into the plaster as the shears are advanced along a wall.

With these and other objects in view, as will appear as the description proceeds, the invention accordingly consists in the novel features of construction, combination of elements and arrangement of parts hereinafter fully described and having the scope thereof indicated in the appended claims.

In the accompanying drawing, forming a part of this specification, and in which similar characters of reference denote like and corresponding parts:

Figure 1 is a side elevation of a pair of shears constructed in accordance with the principles of the invention,

Fig. 2 is a top plan view thereof,

Fig. 3 is a fragmentary perspective view of the forward end of the stationary blade,

Fig. at is a transverse sectionalview taken along the line 4-4 of Fig. 1,

Fig. 5 is a fragmentary side elevation of "the meeting edges of canvas sheeting employed in finishing a plastered wall, and

Fig. 6 is a horizontal sectional view taken through the sheeting after theoverlapping edges thereof have been cutby the shears. Referring more particularly to the details of the invention, use is made of a pair of shears A which, in its preferred form, consists of a substantially stationary blade 1 and a movable blade 2, the latter being provided with a fixed head stud 3 which is dis posed to operate in the rounded end of a Patented Feb. 10, 1920. w

slot 45 formed in the blade 1. By virtue of this construction said blades may be moved relatively and, if necessary, the same may be disconnected to facilitate the sharpening of their edges. In this instance, said blades are formed with angularly ofi'set manipulating portions 5 and which include finger loops 6, by means of which the shears may be conveniently grasped and operated. Owing to the angular relation of the manipulating portions 5, the shears may be conveniently guided during their cutting movements, as the blade 1 may be maintained in close engagement with a wall or other plane surface while the blade 2 may be oscillated to effect cutting movements. Thus the oscillation of the blade 2 may be accomplished without raising the blade 1 from engagement with said wall owing to the fact that its finger loop 6 will be provided with ample room for oscillation between the finger loop of the stationary blade and the limitations imposed by said wall. This construction of the manipulating portions of the shears renders the latter adaptable for ceiling work as well as for the vertical side walls of a room.

The particular feature of the present invention resides in forming the stationary blade 1 with an integral penetrating pro ection 7, so as to facilitate the insertion of the shears into cutting cooperation with materials to be severed. To this end the projection 7 consists of a flat upper surface 8 which in plan is in the shape of an arrow head, being provided with a forward point 9 and a substantially widened rear portion 10, the portions of the projection below the surface 8 being curved and formed to con verge into the body of the blade 1, as indicated by the numeral 11. By thus curving the projection 7 along its under face, its point 9 is located outside of the resting or operating plane of the blade 1, so that the advancing of the latter across a plastered wall will not be attended by the digging in of the point 9 into said wall, but on the contrary said point will be maintained in spaced relation with respect to said wall. The curved art 11 also acts as a fulcrum when the pro ection 7 is being initially inserted into materials to be cut and serves to facilitate this operation. The widened rear portions10= of the projection 7 serves to enlar e the opening formed thereby so that t e blades 1 and 2 will encounter no difficulty in being brought into cutting relation with the material.

In use, the shears A are particularly adaptable for service in cutting the selvage edges of sheets of wall canvas 12, such as are shown in Figs. 5 and 6 of the drawings. These canvas sheets are preferably placed upon a wall in the manner illustrated in Fig. 5 so that the edges 13 thereof will over lap. Then in order to eliminate the over-- lapping edges and to perfectly match the remaining edges of the sheets, use is made of the shears A. The projection 7 of the latter is forced into the overlap 13 at any desired point throughout their length, and it will be seen that through the provision of the projection 7, the insertion of the shears may be readily accomplished. Then, by holding the blade 1 in engagement with the wall 14 the shears may be guided during their cutting operation and that owing to the angularity of their manipulating portions ample room will be provided to actuate the movable blade. In fact, if the blades 1 and 2 are well sharpened it Will not be necessary to lock the blades, as the latter may be held stationary by the operator and the material severed by simply forcing the blades therethrough. Thus owing to the overlap ping relation of the edges 13 when the cutting operation is performed neatness will be obtained in matching the adjacent edges of the sheeting after the overlapping portions have be em d, and the re ation es ablished wherein divisions or openings between i the sheetings elimin ated,thus permitting the materials to evenly mate together or to unite in a uniform and even manner. While a sp c f r he sh ars has been se forth, 1t is obvious that the same may be also applied to many other different uses such for example, as the trimming of oil cloth, enameled paper, for the separation of bandages in hospital work and many other different fields of utility,

What I claim is:

1. A pair ofshears comprising a substantially stationary and a movable blade, angularly offset finger loops formed with said blades and a substantially arrow head shaped pro ection formed upon the forward end of the stationary blade andserving to facilitate the insertion of the latter into material to be operated upon.
