ATTO EY United States Patent 3,230,620 BAND CUTTER Roy McKinley Embleton, RR. 1, Hannon, Ontario, Canada Filed June 17, 1963, Ser. No. 288,103 3 Claims. (Cl. 30-286) The present invention relates, to a tape cutter and it consists in the combinations, constructions and arrangements of parts hereinafter to be described and claimed.
Generally there is provided a hand tool for the cutting of tape as, for example, surgical tape, bandages, industrial tape and the like. The device consists of a body of metal having novel handle portions aflixed thereto which are formed of Bakelite or the like. A boot portion at the forward end of the body has pivoted thereto an inverted U-shaped guard member which encompasses a triangular blade mounted in the boot by means of adjustable screws. The device is such that the forward edge of the blade may be forced beneath a piece of tape to sever the same and the guard will automatically rise during the cutting process and thereafter again fall into normal position covering the blade. The interior surface of the apex portion of the guard member may be provided with a felt liner which may be oiled from time to time to lubricate and help clean the blade but may be eliminated for sterile purposes when the device is to be used in connection with surgical tape or bandages.
It is accordingly an object of the invention to provide a device of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and efficient in use.
Another object of the invention is to provide, in a tape cutter of the character set forth, a novel guard memher for a blade, said guard member and said blade forming parts of the invention.
A further object of the invention is to provide, in a device of the character set forth, novel means for mounting a blade therein.
A still further object of the invention is to provide, in a device of the character set forth, novel means for protecting and lubricating a blade forming a part of the invention.
Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawing, in which:
FIGURE 1 is a side elevational view, partly broken away, of an embodiment of the invention,
FIGURE 2 is a fragmentary side elevational View illustrating the device at the beginning of a cutting operation with respect to a portion of tape likewise shown in said figure,
FIGURE 3 is a view similar to FIGURE 2 but partly in section and illustrating the actual cutting process,
FIGURE 4 is a fragmentary plan View of FIGURE 1, and
FIGURE 5 is a somewhat enlarged end elevational view of the device illustrated in FIGURES 1 and 4.
Referring more particularly to the drawing, there is shown therein a device of the character set forth comprising an elongated body extending, as illustrated, in a horizontal direction and having aflixed to each side thereof by means of rivets 11 or the like a pair of handle "ice members 12 which may be of wood, Bakelite or like material.
Integrally formed with the forward end of the body 10 is a downwardly extending boot 13 having a forwardly extending centrally located slot 14 formed therein.
A triangular blade 15 is centrally mounted in the slot 14 by screws 16 extending into each side of the boot 13 and bearing upon either side of the blade 15 and a screw 17' extending through the rear of the boot 13 into the slot 14 and bearing against the rear side of the blade 15, as illustrated in FIGURE 3.
It will be seen that the sharpened edge 17 of the blade 15 extends angularly forwardly and downwardly and that the forward corner 18 of the blade 15 abuts against a shoulder 19 formed in the forward edge of the slot 14.
A guard member 20 of inverted U-shape is provided with a pair of upwardly and rearwardly extending ears 21 which are pivotally connected by means of a pin, rivet or the like 22, to the sides of the boot 13. The inner side of the bight portion of the guard 20 has aflixed thereto, if desired, a felt pad 23.
In operation, it will be seen that the device may be grasped by the handle 12 and the forward edge of the boot 13 extended beneath a piece of tape 24 to be severed, as indicated in FIGURE 2 and thereafter forced the remainder of the way across said tape to entirely sever the same, as is illustrated in FIGURE 3 and that when such action occurs, the guard 20 having an upwardly and forwardly extending forward edge 25, will be lifted upwardly as it passes over the tape 24 while the blade edge 17 performs its severing operation and that, when such operation is completed and the tool removed, the guard 20 will descend to its normal position whereupon the felt 23 will come to rest upon the sharpened edge 17 of the blade 15. Normally the felt pad 23 will be saturated with oil to protect and lubricate the blade and help keep the same clean. When, however, the device is to be used with surgical tape, bandages or the like, the felt pad 23 may be eliminated or kept in a dry state.
While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made without departing from the spirit of the invention or the scope of the appended claims.
What is claimed is:
1. A tape and bandage cutter for lifting and severing tape and like material on an article and comprising; an elongated handle body portion; a dependent generally L-shaped boot formed at the forward end of said body; blade supporting means forming the lower portion of said L-shaped boot and oriented along an axis generally parallel with the axis of said handle body portion and directed forwardly thereof and defining a generally flat bearing surface along the exterior lower edge thereof; a blade removably mounted in said boot and supported by said supporting means with the edge of said blade directed at an angle relative to the axis of said handle body portion and oriented with the said angled edge extending upwardly and rearwardly from said supporting means towards said handle body portion; an inverted U-shaped guard pivotally mounted on said boot and encompassing the full length of said blade, and said boot and blade supporting means and guard raising means on each side of said guard depending downwardly on each side of said boot, said blade supporting means and below the same and extending downwardly below said bearing surface for raising thereof upon contact of said bearing surface with said article and prior to cutting by said blade.
2. A device as defined in claim 1 wherein said guard has afiixed to the underside thereof a felt mat,
3. A device as defined in claim 1 wherein said boot is provided with a shoulder at the forward end of said slot, wherein screws extend inwardly from each side of said boot to bear against said blade, and wherein a screw extends through the rear of said boot to bear against the rear of said blade to force the forward end of said blade to abut against said shoulder.
