TINTTED STATES PATENT HENRY K. LPORTER, 015' BOSTON, MASSACHUSETTS.

CUTTING-TOOL.

Application filed March 27, 1915.

To all whom it may concern:

Be it known that I, HENRY K. PORTER, a citizen of the United States, residing at Boston, in the county of Sufl'olk and State of Massachusetts, have invented new and useful Improvements in Cutting-Tools, of which the following is a specification.

This invention relates to improvements in cutting tools and more particularly to tools constructed and arranged to cut wires, bolts and the like, and is designed as an improvement over the type of bolt clipper disclosed in my U. S. Patent No. 909,663.

The object of this invention is to provide a strong, durable cutting tool which is particularly adapted for use in warfare for severing and removing barbed wire entanglements, and to facilitate such use of the cutting tool, guide members have been provided which extend divergently outward from the sides of the cutting-members in order to assist in the guiding of the work to be out between the cutting edges of the cutting levers. Said guide members terminate at their outer extremities in hooks which enable the manipulator of the tool to pull tangled masses of wires from his path with out necessitating the handling of said wires.

A further object of the invention is to provide means whereby the device may be suspended from the belt.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims.

Referring to the drawings: Figure 1 is a plan view of a cutting tool embodying my invention, portions of the handles of said tool being broken away to save space in the drawings. Fig. 2 is a side elevation, partl v in section, of the cutting tool shown in Fig.

1. Fig. 3 is an underneath plan view of the guard, resilient abutment and ring, the cutting levers of said tool being illustrated in dotted lines. Fig. 1 is a section taken on the line 44 of Fig. 1. Fig. 5 is a view similar to Fig. 3 illustrating a modified form of guard and in which form the guard constitutes one of the straps of the cutting tool. Fig. 6 is a section taken on the line 6-6 of Fig. 5. I v

Like numerals refer to like parts throughout the several views of the drawings.

In the drawings, 8, 8 represent a pair of cutting levers which are pivotally connected together by suitable pivots 9, 9 extend- Specification of Letters Patent.

ing through said levers 8 and two straps 10 and 11 arranged upon opposite faces of the cutting levers. The butt ends of the levers 8 are pivotally connected at 12 to handles 13 which in turn are pivotally connected together at 14. The outer free ends of the cutting levers 8 are provided with cooperating edges 15. In cutting tools of this kind the jaws are not usually permitted to be opened very wide, in fact, only slightly wider than the work for which the tool is designed to cut, consequently in reaching for work it is sometimes diflicult to strike the same every time and especially would such be true when the user of the device is in. a hurry and the light is rather poor. To overcome such a difficulty a guard 16 has been provided, which guard is secured to one 4 face of the cutting tool against the sides of the cutting levers 8, 8. A recess 17 has been provided in the face of said guard adjacent said cutting levers to receive the strap 10, which is on that side of said levers. The guard 16 may be secured to the device in any suitable manner. The preferred method however is to secure the same by a screw 18 arranged substantially at the center of said guard and extending into the strap 10. l

The guard 16 embodies in its construction a pair of guide members 19 which extend divergently from adjacent the strap 10 along the sides of the cutting levers 8 to points at substantial distances beyond the free ends of said cutting levers. The inner edges 20 of said guide members are arranged to substantially aline with the cutting edges 15 of the levers 8, when said levers are open, see Fig. 3, thus providing a wide and smooth approach to the cutting edges for guiding the work therebetween. The outer extremities of theguide members 19 are turned outward relatively to each other and backward to form hooks 21, 21 which may be used to rip or pull wires from posts and to remove tangled masses of wire from the path. As has been previously stated, the guide members 19 extend substantially from the strap 10 or from points adjacent the axes of the cutting levers. The opening 22 therefor which is between said guide members and into which the wire is inserted extends beyond the inner ends 23, 23 of the cutting edges 15, especially when the jaws or levers 8 are open, as in Fig. 3. Should this be permitted to remain so any small wire which might be inserted between the cutting edges PatentedJuly 6, 1915.,

of said tool would be so far within the cutting edges that it would not be severed by the closing of said cutting levers. To limit the insertion of the work between said jaws and to permit the work to yield slightly during the cutting thereof an abutment 24 is arranged adjacent the inner end of the opening 22. Said abutment is preferably constructed of a resilient strip or strips of metal which are arranged transversely of the opening between the cutting edges 15 of said levers 8 and extend into recesses 25 formed upon the inner face of the guard 16, or in other words, the face of said guard which engages the faces of the levers 8. Abutments 26 are formed within said recesses and engage said resilient abutment at points a short distance from the ends thereof, thus providing a solid support for said resilient members and permitting straight and, if de sired, flat sections of spring steel to be used and permitting the number thereof'to be increased according to the resistance desired. Stops 27 are also formed within said recesses to engage the opposite face of the resilient abutment, said stops being at such distances from the abutments 26 that said resilient abutment 24; must be slightly deflected when inserted in order to securely hold the same in position.

For convenience in carrying the cutting tool from place to place a ring 28 has been pivotally mounted thereon, which ring may be attached to the belt of the person carrying the same, said ring being secured to the guard 16-, preferably by means of a hook 29 formed integral with said guard and having its open portion 30 adjacent the sides of the levers 8. Thus when said guard is secured in place over the strap 10 the opening in said hook will be substantially closed and the ring 28 locked therein.

In Figs. 5 and 6 modified form of guard is illustrated. In this form the base portion 31 of the guard 16 is adapted to ta-ke'the place of the strap 10 and is secured in place against the cutting lovers of the tool by the pivotal connecting means 9 shown in Fig. 4, which pass through holes 32 in the base 31. Otherwise the form illustrated in Fig. 5 is substantially as hereinbefore described.

Having thus described my invention what I claim and desire by Letters Patent to secure is:
