CABLE-CUTTING DEVICE.

H I Patented Get. 14, 1913.

. To all whom it may concern Be it known that 1, WILLIAM T. QUINLIN, a citizen of the United States, residing at Coalinga, in the county of Fresno and State of California, have invented certain new and useful Improvements in Cable-Cutting Devices; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

This invention relates to improvements in devices for cutting wire cables.

One object of the invention is to provide a device of this character which is particularly adapted for cutting wire cables containing a number of strands and which is designed to hold, the ends of the strandsor wires in close compact form when out and to prevent any pieces of the wire from flying out and injuring the operator.

Another object is to provide a cable cutting device which may be applied to a cable at any point between the ends thereof thus obviating the necessity of insert ng the end ofthe cable through the device and which will make a clean out through the cable at one place only.

Wlth these and other objects in view, the invention consists of certain novel features of construction; and the combination and arrangement of parts as will be more fully described and claimed...

In the accompanyingl'd'rawings; Figure l is a side view of my improved cable cutting device; Fig. 2 is an enlarged central vertical longitudinal section thereof; Fig. 3 is a top plan View of the lower section or member of the devicefFig. i is a vertical cross section thereof taken on the line H of Fig. 2; Fig. 5 is a similar view taken on the line 55 of Fig. 2; Fig. 6- is a similar view taken on the line 6- of Fig.2; Fig. 7' is a detail side view oft-he movable cutting bit of the device; Fig. 8 is a perspective view of the stationary cutting bit' ofthe device; Fig. 9 is a similar view" of the spring fior preventing the rebounding-of the movable cutting bit when operated to-cut the cable;

Fig. 10 is a similar view of oneoi the combined clamping devices and'h'an'dlesfof the device. I

My improved cable cutting device coniprises a body ortion consistin of upper and lower menu are 1 and 2 in the; fermof substantially oblong metal blocks. In the upper side of the lower member 2 of the block is formed a semi-circular groove 3 while in the lower side of the upper member is a similarly disposed semi-circular groove 4. ,When the upper andlower members-o1- blocks 1 and 2 of the device are brought to gether in operative position the grooves 3 and 4 therein register and form a central longitudinally disposed assage with which the cable is engaged at t e point where the latter is to be cut as clearly indicated in Fig. 2 of the drawings. By constructing the body of the device in separable sections as herein shown and described it will be seen that the same may be applied to a cable at any point in the length thereof thus ob-.

viating the necessity of inserting and drawing the cable throu h the device in order to reach the point .w ere the cable is to be severed.

When the members or blocks 1 and 2 of the device are'engaged with the cable in the manner described, said blocks are clamped together and securely fastened in operative engagement by combined clamping members' .an'd'handles 5 comprising rectangular framesjhavin'g therein suitably located cross bars 6 and having their lower sides formed I by the inwardly turned lower ends 7 of the vertical sides of the frame, said in-.

Wardly turned ends terminating-a short distance from the sides of the frames and forming gripping lugs as clearly shown in Figs. 6 and 10 of the drawings. In the lower side ofthe lower member or block 2 of the device at the point where the clamping members are engaged therewith are formed transverse grooves 8 with which the endsof the lugs 7' of the clamping members 5 are engaged and by which said lugs are held in position. a

The upper sides of the ends or the upper member 1 of the device are beveled or inclined outwardly and downwardly as shown at 9 to facilitate the engagement of the over the ends of the device. In swinging the clamping members inwardly over the beveled ends 9 of the device the forcible enagement of the cross bars with'said beve ed ends ofthe upper block 1 will draw and v clamp the upper and lower blocks into tight engagement as will be readily understood. By leaving the lower sides of the clamping members 5 open or constructing said lower sides in the form of the lugs 7 it will be seen that the open space left between the lugs will permit the clamps to be let down over the cable at the ends of the blocks 1 and 2 so that said members may be readily engaged with the ends of the device Wherever the same is placed on the cable.

In the upper side of the lower member or block 2 of the device is formed a centrally disposed recess 10 adapted to receive the lower stationary cuttingbit 11 of the device, said bit comprising a block of hardened steel the lower portion of which is adapted to closely fit the recess '10 and the upper portion of which projects above the upper side of the lower block 2 and engages a recess 12 formed in the lower side of the upper block 1 as clearly shown in Figs. 2 and 4 of the drawing. upper portion of the bit 11 is formed a V- shaped notch 13 the walls of which are beveled or inclined from the inner toward the outer side of the bit as shown at 14 thereby forming at the inner side of the block a sharp cuttin edge 15. Also'formed in the upper side of the lower block 2 adjacentto and communicating with the recess 10 is a passage 16 which is of less width than the recess 12 and is adapted to receive the lower end of the movable cutting bit hereinafter described. The passage 16 preferably extends entirely through the lower block, as shown.

In the upper block or member 1 adjacent to and communicating at its lower end with the recess 12 is a vertically disposed rectangular passage 17 which extends entirely through the upper block 1 as shown. Slida'bly engaged with the passage 17 is a movable cutting bit 18 comprising a hardened steel bar having a cross sectional shape corres ending to the shape of the passage 17 an having a length greaterthan the thickness of the upper member 1 of the device. The lower end of the bit 18 is curved and beveled as-at 19 to form a cutting edge 20 which is adapted to co-act with the cutting edges formed by the V-shaped notch in the lower stationary bit/11. v

In one side of the bit 18 are formed a; series of ratchet teeth 21 with which are engaged the downwardly turned outer end of a spring pawl 22 which is preferably in the form of a flat spring metal plate havingtherein near its outer end a rectangular slot 23 with. which is engaged a bolt 24 the inner.

end ofwhich is secured in theupper side of the upper member 1 of the device and with the upper end of which is engaged a clamp-v ingnut 25 which when screwed down on the bolt securely clamps the slotted end of the pawl to the upper member 1 in such posi- In the projecting tion that the free end of the pawl engages the ratchet teeth 21 on the bit 18 and prevents the' latter from rebounding after be ing operated to cut the cable as will be hereinafter more fully described. By roviding the slot 23 in the end of the paw the latter may he slipped back when the clamp ing nut is released thereby disengaging the outer end of the pawl from the ratchet teeth on the bit 18 to permit the latter to be retracted.

In the operation of my improved cutting device the upper and lower members thereof are engaged with the cables at the point where the same is to be cut and when so engagedthe cable will lie in the V-shaped notch of the lower or stationary bit 11 as clearly, shown in Figs. 2, 1 and 5 of the drawings. After the device has thus been applied to the cable and the clamping members 5 adjusted to fasten the blocks 1 and 2 together around the cable in the manner described, the movable cutting bit 18 is broughtdown into forcible engagement with the cable by a blow from a hammer or other instrument. When thus forced downwardly the co-action of the cutting edge on the lower end of the bit 18 with the cutting edges of the stationary bit 11 will sever and make a clean cut through the cable. The engagement of the spring pawl with the ratchet teeth 21 on the bit 18 will positively prevent the bit from rebounding after being struck and will thus cause the bits to cut the cable at one point only, or in other words will prevent the blades from gashing or making a ragged out, should it be necessary to impart a second blow to the bit. The ends of the cable or the strands thereof when out in the manner described will be confined and prevented from falling apart by the walls of the passage formed by the grooves in the engaging sides of the upper and lower members of the device and will thus obviate any danger of injury to the' operator by the flying strands or particles of metal which frequently occurs in cutting woven or twisted wire cable in the usual manner.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to withoutdeparting from the principle or sacrificing any of the advantages of the invention as shown.
