Patented Mar. 3, 1942 'ROLL PAPER CUTTER Neil B. Currier, Los Angeles, (JaliL, assignor of I one-half to Lynn H. McClintock and one-half to Florence L. McClintock, both of Los Angeles,
Calif.
Original application AugustZ, 1940, Serial No. 349,913. Divided and this application February 26, 1941, Serial No. 380,638 1 5 Claims.
My invention relates to a roll paper cutter and the subject matter herein illustrated and described is a division of my copending application for U. S. Letters Patent on roll paper cutter filed August 2, 1940, Serial No. 349,913.
The principal objects of my invention are, to generally improve upon and simplify the construction of the existing forms of paper cutters. particularly those used for cutting wrapping paper, light weight cardboard,-corrugated wrapping paper, light weight leather, or the like, and further, to provide a simple, strong, durable and efficient cutter, that is mounted for sliding movement upon a cutter bar over which the web of paper passes and said cutter carrying a pair of oppositely arranged blades so as to enable the paper or other material to be severed as the cutter is moved in either direction upon the cutter bar or supporting rail.
A further object of my invention is, to mount the sliding cutter upon the cutterbar or rail so that it will travel thereon with minimum friction, and further, to construct the body of the cutter between the blades so that very little, if any, resistance will be offered to the cutter body by the edges of the severed material during the cutting function.
With the foregoing and other objects in view, my invention consists in certain novel features of construction and arrangement of parts that :34
will be hereinafter more fully described and claimed and illustrated in the accompanying drawing in which:
Fig. 1 is a front elevational View of a cutter of my improved construction and showing the same mounted for sliding movement upon a cutter bar.
Fig. 2 is a horizontal section taken in a plane just above the top of the cutter bar.
Fig. 3 is a vertical cross section taken on the line 3-3 of Fig. 1.
Fig. 4 is a vertical cross section taken on the line 44 of Fig. 1.
Referring by numerals to the accompanying drawing which illustrates a preferred embodiment of my invention, I0 designates a cutter bar L w of metal I2 which may be several inches in length and formed in the upper and lower portions of said block are longitudinally disposed slots I3 for the accommodation of those portions of the front Wall of the cutter bar II'I above and below the slot II.
Projecting into the tubular cutter bar from the intermediate portion of block I2 is a stud I4, on the rear portion of which is mounted for rotation a roller I5, the periphery of which bears against the under side of the top wall of the cutter bar, thus providing a rolling bearing that maintains the cutter in proper upright position while travelinglongitudinally of the cutter bar.
Formed integral with the top of block I2 in front of the upper one of the slots I3 therein is an upwardly projecting plate It considerably shorter than the block I2, and the upper end of this plate is increased in length so as to form extensions I1 that occupy positions above the end portions of block I2.
Formed integral with the upper edges of the plate It and its extensions I1 is a longitudinally disposed tubular member I8 that functions as a handle for manipulating the cutter. Formed in the lower portions of the extensions I! are oppositely inclined slots I9 for the reception of the reinforced upper portions of cutters C. These cutters may be a standard form of safety razor bladesand which are readily obtainable in the open market.
Formed integral with and extending downwardly and outwardly from the lower edges of the extensions H to the sides of the slots I9 therein are substantially triangular plates 25 that overlie and provide guards for the outer upper end portions of the cutting blades C.
Formed in the top of block I2 in front of the upper one of the slots I3 therein is a slot or recess 2I for the accommodation of the lower inner corners of the cutters C. When the cutting blades are properly positioned on the cutter, the lower inner corners of said cutters project downwardly past the plane occupied by the top of the cutter bar I0, and the lower corners of said cutters terminate within the slot 2|.
The lower portion of plate I6 or that portion just above the block I2 has its side portions made substantially wedge-shape in horizontal section, with the apices thereof outwardly presented in order that said plate will pass freely through the slits that are cut across the web of paper by the blades while the cutter is in use, thereby enabling the cutter to be moved lengthwise of the cutter bar with minimum resistance offered by the paper or material that is being cut.
In the use of my improved cutter, the same is positioned at one end of the cutter bar and the web of paper or other material to be cut is drawn forwardly from the supported roll of paper across the cutter bar until the desired amount of paper projects in front of said cutter bar. The handle I8 is now grasped by the operator and the: cutter is moved lengthwise upon the cutter bar and the forward one of the cutting blades will sever the Withdrawn portion of the paper along a line immediately in front of the cutter bar.
While not in use, the cutter occupies an outof-the-way position upon either end of the cutter bar.
As the cutter moves lengthwise upon the cutter bar, the roller IE will ride against the under surface of the top of the cutter bar, thus maintain-- ing the cutter in proper upright position and materially reducing any friction resulting from the movement of the cutter and immediately after the blade severs the paper, the edges along the line of cut will engage against the inclined faces of the wedge-shaped portions of plate [5, thus affording minimum resistance to the travel of the cutter while the same is in use.
It is to be understood that the cutters C are readily removable from the slots l9 in the end portions I! of plate l6 so that when the cutters become dull they may be quickly removed and replaced by sharp cutters.
Thus it will be seen that I have provided a roll paper cutter that is relatively simple in construction, inexpensive of manufacture and very effective in performing the functions for which it is intended.
,It will be understood that minor changes in the size, form and construction of the various parts of my improved roll paper cutter, may be made and substituted for those herein shown said block, a handle on the upper portion of said plate and those portions of said plate between the inner ends of said cutter being substantially wedge-shape in cross section.
2. In a roll paper cutter, the combination with a tubular cutter bar provided with a longitudinally disposed slot, a block mounted for sliding movement on said cutter bar and having a portion that projects through the slot therein, a plate projecting upwardly from the center of said block, inclined cutters carried by the ends of said plate and positioned above the end portions of said block, a handle on the upper portion of said plate and with oppositely arranged inclined faces formed on both sides of said plate above said block and between said cutters.
3. In a roll paper cutter, the combination with a tubular cutter bar provided with a longitudinally disposed slot, a block mounted for sliding movement on said cutter bar and having a portion that projects through the slot therein, a plate projecting upwardly from the center of said block, inclined cutters carried by the ends of said plate and positioned above the end portions of said block, a handle on the upper portion of said plate, those portions of said plate between the inner ends of said cutter being substantially wedge-shape in cross section and a roller journalled on that portion of the block that projects into said cutter bar for engaging the inner face of one of the walls of said cutter bar.
4. In a roll paper cutter, the combination with a tubular cutter bar provided with a longitudinally disposed slot, a block arranged for sliding movement on said cutter bar and having a portion projecting through the slot therein, antifriction means carried by that portion of the block that projects into the cutter bar, which anti-friction means is adapted to engage the inner face of one of the walls of said cutter bar, a plate projecting upwardly from the center of said block, the side portions of which plate immediately above the block are substantially wedgeshape in horizontal section, extensions on the upper portion of said plate and cutters removably mounted on said extensions.
5. In a roll paper cutter, the combination as set forth in claim 4 and with a handle carried by the upper portion of said plate and said extensions.
