INVENTOR JOHN A. MATTERA EE/"m, @Za/M M ATTORNEYS United States 3,008,234 HYDRAULICALLY ACTUATED TOOL John A. Mattera, Jackson Heights, N.Y., assignor to The Welsbach Corporation, Philadelphia, Pa. Filed July 27, 1959, Ser. No. 829,874 4 Claims. (Ci. 30-223) This invention relates to cutting, punching and crimping tools and more particularly to such tools which are hydraulically actuated.
Heretofore various hydraulically actuatedtools have been proposed and some particularly adapted for cutting of wire and multi-wire conduits or cables. One such hydraulically actuated cutting tool is shown in the patent to Northcutt No. 2,578,582 of December 11, 1951.
Certain of these known hydraulically actuated tools have disadvantages in excessive weight, cumbersomeness, excessive bulk prohibiting use in restricted spaces, and difliculty in conversion of the tool for multiple purposes to perform various operations.
The present invention, for the first time, provides a hydraulically actuated tool which is light in weight, compact, readily usable in restricted space and easily and conveniently employed for various purposes including cutting, punching, and crimping, particularly for multistrand cable and wire.
It is accordingly an object of the present invention to provide a novel light weight, compact, rugged and powerful hydraulically actuated tool which can be used in restricted space.
Another object is to provide such a tool which is easily converted to perform various tasks such as cutting, punching, and crimping.
Another object is to provide such a tool having novel components readily associated therewith for cutting, punching, or crimping.
Other and further objects of the present invention will appear from the following description of an illustrative embodiment thereof.
This invention is capable of various mechanical forms and the following illustrative embodiment thereof should in no way be construed as defining or limiting the present invention.
In the accompanying drawings, in which like reference characters indicate like parts, an embodiment of the present invention is shown in cross sectional elevation in FIG. 1 to illustrate the arrangement of elements of the basic tool;

FIG. 12 is an enlarged detail of the knife holder seen in FIG. 11;
FIG. 13 is a side view of the knife seen in FIG. 11, and
FIG. 14 is a view from above of the knife of FIG. 13.
A swam Patented Nov. 14, I961 Referring now more particularly to FIG. 1, the illustrative embodiment of the tool of the present invention there shown is seen tocomprise a cylindrical base axially bored at 21 and internally threaded at 23 to receive hollow fitting 24 to connect bore 21 to a suitable source of hydraulic fluid under pressure, not shown. Sleeve 25 surrounds base 20 and is suitably secured thereto as by welding or by shrinking thereon. Base 20 is reduced in diameter at 26 to form shoulder 27 and the axial bore through extension 26 is reduced at 28 to form shoulder 29. Rod 30 is mounted for axial movement in bores 21 and 28 and is provided with head 31 to receive spring 32 which surrounds and extends along rod 30 and engages shoulder 29. Rod 30 is threaded at 33.
Piston 40 is mounted for reciprocating movement in bore 36 and is provided with head portion 41 which is internally threaded at 42 to receive threads 33 of rod 30. A suitable sealing ring 43 is mounted on head 41 to prevent leakage of hydraulic fluid past piston 40. Piston 4i) is provided with cylindrical stud 44 which is bored at 45 to receive set screw of the tool components as will appear more. fully hereinafter.
Referring now to FIGS. 37, a head 34 is there shown with cylinder 40* extending into opening 49 to perform a punching operation. A punch base 54 is mounted on head 44 and secured thereto by set screw 55 entering bore 45. Punch 56 extends axially from base 54 and passes through punch face plate 57 which is resiliently mounted with respect to base 54 by springs 58. Punch base 54 is provided with axiallyextending flanges 59 and 60 received in slot 53 to guide base 54 during its axial movement in opening 49.
As seen in more detail in FIGS. 57, punch base 54 is axially bored at 68 to receive stud 44 and has a reduced bore at 69 to receive punch 56. Base 54 is additionally bored at 70, 71, 72 and 73 to receive springs 58 and each of springs 58 may be provided with spring rods 74 which are threaded at 75 for mounting in face plate 57. Rods 74 are provided with heads 76 which are mounted in apertures 77 formed in base 54 to permit movement of plate 57 until springs 58 compact, as in FIG. 2.
From the above it will be readily apparent that base 54 is easily and readily mounted in slot 53 and secured on stud 45 while anvil 61 is easily and readily mounted in slot 53 and seated in hook 47.
The punching operation of the tool of the present invention is readily understood from the description above of FIGS. 2-7. With punch base 54 and anvil 61 mounted as above described, the application of hydraulic pressure through fitting 24 on piston 40 moves piston 40 to the left compressing spring 32. Work piece 67, which is positioned adjacent anvil 61, is first engaged by plate 57 to hold work piece 67 in position and continued movement of piston 40 to the left compresses springs 58 allowing punch 56 to pass through plate 57 and into engagement with work piece 67 to punch out slug 66 which is received in bore 65 of anvil 61.. When the punching operation is completed, release of hydraulic pressure on piston 41 will permit spring 32 to return piston 48 to its initial position as seen in FIG. 1 preparatory for the next work stroke. 7
FIGS. 8-10 illustrate the tool of the present invention employed for crimping. Crimper head 78 is mounted on stud 44 and is secured in place by set screw 79 and is provided with opposed flanges 80 and '81 seated in slot 53 to guide head ,78 during movement thereof in opening 49. Head 78 may extend laterally on each side of tool head 44 and is provided with spacer crimper points 82 and 83. Stud 44 is received in bore 84 in crimper head 78. Crimper anvil 85 is provided with fin 86 whichis received in slot 53 of hook 47 and anvil 85 is rounded at 87 for snug fit in rounded surface 63 of hook 47. Anvil 85 is provided with groove 88 to receive the work piece 89, which is illustrated as .a multi-filament wire or cable on which sleeve 90 is tobe crimped.
The crimping operation of the tool of the present invention should be apparent from the description above of FIGS. 8-10. When sleeve 90 is to be crimped upon the wire or cable 89 the sleeve is placed over the wire; anvil 85 is mounted in hook 47 and crimper head 78 is mounted on stud 44. The cable and sleeve are then placed in groove 88 of anvil 35 and hydraulic pressure is applied to cylinder 40 moving the same to the left in FIG. 8 to bring crimper head 78 and crimper points 82 and 83 into engagement with sleeve 90. Crimper points 82 and 83 then act to crimp sleeve 90 on cable 89. Release of hydraulic pressure allows piston 40 to be moved to the right in FIG. 8 under the action of spring 32 to initial or starting position to permit cable 89 and crimped sleeve 90 to be removed from groove 88 of anvil 85.
FIGS. 11-13 show the tool of the present invention employed as a cutter. Base 91 is mounted on stud 44 by set screw 92 and is provided with an axial slot 93 to receive knife blade 94. Set screws 96 are suitably mounted in base 91 and pass'through suitable holes 97 in blade 94 to secure blade 94 in slot 93. Blade 94 is preferably provided with an angularly disposed cutting edge 98 to provide a shearing action and edge 98 is preferably ground to the angles shown in FIG. 14. With blade 94 mounted in base 91 and with base 91 mounted on stud 44, as above described, the work to be cut is caught in the curved surface 63 of hook 47, as shown in FIG. 11 Where a multistrand wire 99 is to be severed. Hydraulic fluid under pressure is then applied to piston 40 moving piston 40 and knife blade 94 to the left as seen in FIG. 11. Knife blade 94 engages work piece 99 and forces the same into hook 47 and continued movement to the left of knife blade 94 then shears and cuts work piece 99, blade 94 moving into and through slot 53 in hook 47. Release of'hydraulic pressure on piston 40, as before, allows piston 40 to move to the right under the action of spring 32 and moves knife 94 to the right to its initial position for the beginning of a new cutting cycle.
It should now be apparent to those skilled in the art that the hydraulically actuated tool of the present invention in every way satisfies the several objectives described above.
Changes in or modifications to the above described illustrative embodiment of the present invention may now be suggested without departing from the present inventive concept. Reference should therefore be had to the appended claims to determine the scope of this invention.
