MARKING 0R CUTTING TIP FOR FLEXIBLE RULE WITH COMBINATION RULE GUIDE AND TIP GUARD Filed May 15, 1965 [IV VEN TOE 20 15. .DINE ON BY WMWW' ATTORN Y United States Patent 3,192,630 MARKING 0R CUTTING TIP FOR FLEXIBLE RULE WITH COMBINATIGN RULE GUIDE AND TIP GUARD Leo H. Dineson, 1770 Conrad Ave, San Jose 24, Calif. Filed May 13, 1963, Ser. No. 279,819 6 Claims. (Cl. 33-42) The present invention relates to a marking or cutting tip for a flexible rule and it includes a guide for the rule that also acts as a guard for the tip when the rule is in retracted position. The invention consists in the construction, combination and arrangement of parts hereinafter described and claimed.
The invention relates generally to the marking and/ or cutting of wallboard, plywood and sheet metal. The marking and/or cutting tip can be attached to any commercial roll tape measure. The marking tip is preferably permanently attached to the end of a flexible rule that is adapted to be wound up within a housing when the rule is not in use. The cutting tip is preferably permanently attached to the end of another flexible rule which is similar to the first one. It is possible to use only one flexible rule and have the marking tip and the cutting tip removably secured to the end of the rule so that either one may be used. When once the marking tip is attached to the end of the rule, it takes the place of a pencil and when the cutting tip is attached to the end of the rule, it takes the place of a knife.
A further object of my invention is to provide a combined guide for the marking or cutting tip, this guide also actingas a guard for protecting either the marking or cutting tip when the rule is retracted into the casing or housing and only the marking or cutting tip is exposed. The combined guide/ guard can be attached to the housing ofa commercial flexible ruler or roll tape and one of the screws in the housing is used for pivotally securing the guide/ guard in place. The guide/guard can be rotated from operative into inoperative position and when it is in the latter position, the bottom wall of the tape casing is free of obstruction and the flexible ruler can be used in the conventional manner.
When the combined guide/ guard is used as a guide, it has a portion that will ride on the edge of the material that is to be marked or cut. The tape housing can be moved back and forth and the guide will bear against the material edge and cause the mark or cut that is made, to parallel the edge of the material. The combined guide/ guard functions as a guard for the marking or cutting tip when in inoperative position and will protect the tip and also protect the operators hands from being marked or cut by the tip.
A further object of my invention is to provide a device of the type described which is extremely simple in construction and can be readily attached to the housing and flexible tape of a commercial tape ruler. The marking and cutting tips will give more accurate workmanship in the marking or cutting of material. It is not necessary to score the measured material. The workman can speed up his operations with the device while still doing accurate work.
Other objects and advantages will appear as the specification continues. The novel features of the invention will be set forth in the appended claims.
Drawing For a better understanding of my invention, reference should be made to the accompanying drawing, forming part of this specification, in which:
FIGURE 1 is an isometric view of a commercial flexible tape rule and housing in .whiclLa spring mechanism, not shown, is used for retracting and rolling the tape within the housing. My marking or cutting tip is shown applied to the free end of the tape and my guide/ guard is pivotally secured to the housing and is shown in operative and inoperative position.
FIGURE 2 is a front elevation of the marking tip shown on a greatly enlarged scale.
FIGURE 3 is a top plan view of the marking tip.
FIGURE 4 is an end view of the marking tip.
FIGURE 5 is a front elevation of the cutting tip shown on the same scale as FIGURE 2.
FIGURE 6 is an isometric view of the guide/ guard.
While I have shown only the preferred form of my invention, it should be understood that various changes, or modifications, may be made within the scope of the annexed claims without departing from the spirit thereof.
Detailed description In carrying out my invention I make use of a roll tape housing for a flexible ruler, the housing being indicated generally at A in FIGURE 1. This roll tape housing may be of any commercial standard type and it receives a flexible ruler indicated generally at B that can be rolled up inside the housing A when not in use. The ruler B is usually provided with a tip C that is secured to the end of the flexible tape by a rivet 1 or other suitable fastening means. The usual ruler tip C is angular in shape and it has a downwardly depending portion 2. My marking tip or cutting tip can be secured to the downwardly depending portion 2 of the tip C. In FIGURE 1, I
show my marking tip D secured to the downwardly dethat opens out onto the flat top 3. The recess or pocket 4 has a width equal to thethickness of the downwardly depending portion 2 of the tip C. The inner edge of the recess or pocket 4 is curved as at 4a and this curvature corresponds with the curvature of the end of the downwardly depending portion 2.
The outer end of the marking tip D is rounded cated at 5 and this rounded end is made pointed as at 5a so that the pointed portion forms an arcuate edge that will constitute a marking edge for the marking tip D. The composition of material forming the marking tip D of equal amounts of lead and tin causes the marking tip to act like a pencil. The sides of .the marking tip that extend to the arcuate edge 5a are inclined and the edge 5a is centered with respect to the width of the recess 4 in the marking tip D so'that the edge 5a will lie in a plane that extends through the zero marking disposed at the outer end of the flexible ruler B.
The composition of the'marking tip D is such that it can be compressed after it is applied to'the standard tip C and this will cause the marking tip to be rigidly and permanently secured to the standard tip. If desired, the marking tip can be welded to the standard tip C.
I will now describe the cutting tip E. The cutting tip is similar in size and shape to the marking tip D and corresponding portions will be given the'same reference numerals except that they will be primed. The recess o'r pocket 4' in the cutting tip receives the depending portion 2 of the standard ruler tip C, after the marking tip D is removed. In actual practice, however, the workman would preferably 'have two rules housed in two separate roll tape housings A. One tape rule would have the marking tip D permanently attached to its flexible tip E permanently attached to its flexible rule B.
Before describing the operation of the cutting tip B,
it is best to describe the combined guide and guard memas indi-.
er F, shown in FIGURES l and 6 in isometric views. This member includes an arm 10 that has an opening 11, see FIGURE 6, for receiving the same screw 12 that is provided for holding the parts of the casing or housing A, together. The arm 1% can pivot about the screw 12 as a center when the guide and guard member F is swung from the full line or operative position in FIGURE 1, into the dot-dash line or inoperative position.
The member F has a spring clip or saddle portion 13 that is integral with and'extends at right angles to the arm 10. The spring clip 13 has a base portion 13a that is designed to be brought into contact with the underside of the housing A when the guide and guard F is swung into operative position about the screw 12 as a pivot. The end of the base portion 13a that is disposed opposite to the arm 10 is provided with an integralclip portion 13b that will yieldingly contact with the housing Wall disposed opposite to the wall that carries the arm. The spring clip 13b yieldingly holds the guide and guard member F in operative position on the housing A.
Both FIGURES '1 and 6 illustrate the member F as having an extension 14 that is integral with the base or saddle 13 and the plane of the extension lies flush with the plane of the base portion 13 of the member F. At the outer end of the extension 14, I provide a flat portion 15 that extends at right angles to the base 13 and acts both as a guide and as a guard. The flat portion 15 is integral with the extension 14 and depends therefrom. When the member 'F is in operative position, the
outer face of the flat portion. 15 lies in the same plane as the outer face of the wall 16 of the ruler housing A, see FIGURE 1. The flat portion 15 has a curved lip 17 at the left hand end of the portion when looking at FIGURE 1. The right hand end could have a curved lip if so desired. The purpose of the curved lip is to prevent the side edge from digging into the edge of the material being marked or cut when the housing A is moved along the edge of the material in a manner hereinafter described. The guide face 15 will therefore move smoothly along the edge of the material as the housing A is moved.
Operation From the foregoing description of the various parts of the device, the operation thereof may be readily understood. When either the marking tip D or the cutting tip E is used, the guide guard member F is swung into the full line position as shown in FIGURE 1. The spring clip 13b will yieldingly contact with the wall 18 of the casing A for holding the member F from swinging about the screw 12 as a pivot. When the member F is in the full line position of FIGURE 1, the outer face 151: of the flat portion 15 will lie in the same plane as the outer face of the casing wall 16. Therefore the operator can use the outer face of the casing wall 16 as an indicating means on the portion of the flexible scale B that projects beyond the casing A.
For example, if the flexible tape B has been extended in FIGURE 1 so that a length of 1 /2 inches projects beyond the casing wall 16, then the outer face of the casing wall 16 will be in line with the 1 /2 inch graduation mark on the flexible ruler. If now the workman desires to draw a line on the material to be cut which is 1 /2 inches from an edge of the material, he will hol the casing A in one hand and bring the face 15a of the flat portion 15-into contact with the edge of the material. The workman will then move the casing so that the face 15:: will ride along the edge of the material and keep in contact therewith. During this movement the operator presses on the tip C to bring the arcuate marking edge 5a of the marking tip D into contact with the surface of the material. As the housing A and the marking tip D are moved, a line will be drawn by the curved edge 5a which will parallel the edge of the material. The operator does not need a pencil to accomplish the marking of the material.
The operator will usually have a second casing A with its flexible tape B and the tip C of the other ruler will have the cutting tip E secured thereto. wishes to make a out along the marked line on the material, he will move the scale B until the 1 /2 inch marking thereon will register with the outer surface of the Wall 16. A cutting line can be made on the surface of the material by moving the housing A so that the outer face 15a of the fiat portion 15 will ride along the edge of the material. A standard piece of sheet rock has its opposite faces covered with paper. a When one of the sheets is severed along a cutting line by the cutting edge 5a of the cutting tip E, then the material can be broken alongthis out line. In this Way no special cutting knife need be used with the flexible tape.
After either the marking tip D or the cutting tip E is used, it can be moved into a position adjacent to the fiat portion 15 of the member F when the flexible tape B is Wound up within the casing. The flat portion 15 y will therefore act as a guard for the marking or cutting tip when it is in inoperative position. prevent thev sharp cutting edge 5a from cutting the operators hand.
It is possible to use the ruler B and housing A in the ordinary manner and the guide guard member F can be swung into an out of the way position as indicated by the dot-dash lines in FIGURE 1 where it will be held from interfering with the normal use of the tape.
The invention is extremely simple in construction and it is durable and efiicient for the purpose intended. The standard casing or housing A and the flexible ruler B I neednot be altered in any respect in order to have my invention operatively connected thereto.-
to the standard ruler tip C. Furthermore the screw 12 in the casing A is used for securing the member F to. the casing. This screw can be removed and then inserted through the opening 11 at the end of the arm. 10, i and then the screw can be reinserted into the casing A for securing the member F to the casing.
The spring clip 131: will hold the member F in operative position for use with either the marking tip or the cutting tip. Also the flat portion 15 will protect the marking or cutting tip when they are not being used. It is also a simple matter to swing the member F into the inopera-.
tive dot-dash line position of FIGURE 1 when the operator wishes to use the casing A and ruler B in the usual manner.
The invention can be used for measuring andmarking or cutting gypsum wall board, plaster lath and Gyplap. If the device were manufactured from suitable materials, it.
It can be used by carpenters for numerous jobs.
could beused by plumbers.
