lGOMBINATIGN TOOL.
APPLICATION FILED APB. 21; 1909.
WILLIAM DUCI-IARME, OF JOHNSTOWN, PENNSYLVANIA.
COMBINATION-TOOL.
To all whom it may concern:
Be it known that I, IVILLIAM Door-mmm, a citizen of the United States, residing at Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and useful Combination-Tool, of which the following is a speciication.
The objects of the invention are, generally, the provision in a merchantable form of a device of the class above mentioned which shall be inexpensive to manufacture, facile in operation, and devoid of complicated parts; specifically, the provision of a device of the class above mentioned in which the handle whereby the lower jaw is operated, may be moved into parallelism with the shank of the upper jaw without altering or disturbing the position of the lower jaw; the provision of a wire cutter, pincers, and a pipe cutter arranged to be used in connection with the handle and the jaws specified; other and further objects being made manifest hereinafter as the description of the invention progresses.
The invention consists in the novel con` struction and arrangement of parts hereinafter described, delineated in the accompanying drawings, and particularly pointed out in that portion of this instrument wherein patentable novelty is claimed for certain distinctive and peculiar features of the device, it being understood that within the scope of what hereinafter thus is claimed, divers changes in the form, proportions, size, and minor details of the structure may be made, without departing from the spirit or sacrificing any of the advantages of the invention.
Similar numerals of reference are employed to denote corresponding parts throughout the several figures of the drawings.
In the accompanying dra-wings Figure 1 shows my invention in side elevation; Fig. 2 shows my invention in side elevation, the jaws being disposed in di'erent positions from those shown in Fig. 1; Fig. 3 is a longitudinal section through a portion of the handle and the lower jaw; and Fig. 4 is a longitudinal section through the shank, designed to show the action of the wire cutting means.
In carrying out my invention, I provide an upper jaw 1, having a shank 2 projecting from its lower face intermediate its ends. :it this point it may be stated that in the following description the wrench is sup- Specication of Letters Patent.
Application filed April 21, 1909.
Patented Mar. 8, 1910. Serial No. 491,304.
posed to be in the position shown in the drawings, the terms upper and lower being selected accordingly. I further provide'a handle 3 which at its upper end is slotted to form arms t. These arms 1 adjacent one edge of the handle are provided with longitudinally disposed slots 5, each of said slots terminating at one end in a lower seat 6 and at its other end in an upper seat 7, the said seats being formed by enlarging and rendering approximately circular in outline, the extremities of the slots 5. Slidably mounted in the slots 5 is a pivot member S which is passed transversely through the lower extremity of the shank 2 of the upper jaw. This pivot member S is approximately semi-circular in cross section, and is so disposed in the shank of the upper jaw, that, when the said upper j aw is thrown backward into a position slightly lower than the one shown in dotted line in Fig. 1, the shorter dimension of the pivot member 8 will be disposed transversely of the slots 5, so that the upper jaw may be moved in the slots from the position shown approximately in dotted lines in Fig. 1 to the position shown in solid line in Fig. 2, the said pivot member 8 traveling in the slots 5, from the lower seats 6 in the first instance, to the upper seat 7 in the second instance. supposing, that the upper jaw 1 stands in a position slightly lower than the dotted position of Fig. 1, it will be seen, that, as soon,
as the upper jaw 1 is raised to a slight degree, that is, into the position shown in dotted line in Fig. 1, the pivot member S will be rotated in the lower seats 6 to bring the longer dimension of said pivot member into transverse relation with the slots 5 so that the pivot member 8 cannot move upward in the slots 5 from the lower seats 6 into the upper seats 7.
Slidably mounted upon the shank 2 of the upper jaw is a lower jaw 9 having an aperture to receive the shank 2. The lower portion of the lower jaw 9 is narrowed as denoted by the numeral 10, and this narrowed portion results in the formation of a shoulder 11 arranged to engage the upper edges 12 of the arms 4. The curved portion 12 of the handle acts as a cam, which, engaging the shoulder 11 of the lower jaw 9, will advance the said lower jaw 9` as the handle moves pivotally upon the member 8. In order to retract the lower jaw 9 from the upper jaw 1, one of the arms 4 is provided with CTC a curvilinear groove 14 in its inner tace, the portion 10 oit the lower jaw 9 being provided with a laterally extending stud 15 arranged to register in the groove 1st and to move therein.
The adjacent faces of the jaws 1 and 9 are longitudinally slotted and the said jaws are provided with transversely alined apertures 1G which communicate with the slots. '.lhese apertures 1G are arranged to receive piutles 17 upon which are jouriialed for rotation in the slots in the t'aces ot the jaws, cutting disks, 18, and 26. Gt' these disks, which are adapted to serve as pipe cutting elements, two are located in the upper jaw 1 and one in the lower jaw 9, the several disks being disposed in a common plane. T he adjacent faces of the jaws are transversely serrated as denoted by the numeral Q0 and these serrations adapt the jaws to grasp and to hold tirmly any object which may be introduced between them.
The jaws 1 and 9 are extended beyond the shank 2 and iii their extended portions are diminished and inbent toward each other as denoted by the numeral 19 to form a pair of shearing edges adapted to serve as a pair of pincers, nail extractors or the like. These elements 19 serve not only the purposes last above pointed out, but at the same time perform the otlice of cooperating lugs adapted to prevent the pipe cutting elements which are assembled with the jaws from moving into contact with each other to their mutual damage. In the drawings, the elements 19 are shown in side elevation only, but it is to be understood that they extend transversely across the entire width of the jaws 1 and 9,y the speciiic illustration of the point last above described being considered unneces sary.
The device is adapted to be used as a wrench, or, when the cutting disks 18, and 2G are mounted in their places in the respective jaws, as a pipe cutter, it being understood that the piiitles upon which the disks are ournaled for rotation, are removably assembled with the jaws oit the device.
As shown to best advantage in Figs. l and 2, the shank 2 is provided intermediate its ends with a transversely disposed tapering aperture 2T. rlhe jaw 9, directly below the aperture 27 in the shank is cut away as denoted by the numeral 2S. A wire may be inserted through the aperture 27, and, upon the operation of the handle the jaw 9 will move upward, engaging the protruding wire and shearing the saine ott neatly. ',lhe a1 erture 2S in the jaw 9 spaces one edge of said jaw away 'from the wire, so that the said wire will be cut oilA by the jaw 9, at one point only. The tapering torni given to the aperture 27 makes the insertion of a wire into the device relatively easy, the small extremity ot the tapered aperture posisaine is in the position shown in Fig. 1, the
cutting disks being removed, however, and the device being adapted to be used as a wrench, it being evident that the description et.' the operation ot the tool will apply with equal propriety when the cutting disks are mounted in place, as shown in Fig. 2.
When the device is iii the position shown in Fig. 1, in solid lines, the jaws 1 and 9 are at their points of nearest apjgiroacli. liVhen the handle 3 is moved pivotally upon the shank 2 of the upper aw, the stud 15 moving in the groove 14 in the arm et will retract the lower jaw 9 into the position shown in broken lines in Fig. 1. i-i nut or bolt-head being introduced between the jaws 1 and 9 and the handle 3 being moved pivotally in a direction opposite to that in which it was moved to open the jaws, the curved portion 12 of the handle engaging the shoulder 11 of the lower jaw 9, will cause the said jaw 9 to move upward, tirmly embracing the nut or bolt head which is included between the jaw 9 and the jaw 1. Supposing, however, that the handle 3 has been moved pivotally to throw the jaw 1 into a position slightly lower than that shown in Fig. 1, that is, to an extent suiiicient to bring the shorter dimension of the pivot member 8 transversely ot the slot 5, it will be seenr` that without disturbing the position of the lower jaw 9, the pivot member 8 will traverse the slot permitting the handle to be brought, as shown in Fig. :2 into substantial parallelisin with the shank Q of the upper jaw. Thus the handle of the wrench may be so shifted, relative to the other parts ot the device, as to exerta longer leverage upon the nut or bolt-head which is to be rotated, lt is obvious, that it the dimensions of the nut which is being rotated are sufi'- cieiit to lill exactly the space between the jaws 1 and 9 when the pivot member S is in a position to traverse the slot the hair dle 3 may be shifted into exact parallelism with the shank Qi. 1n other cases, the relation between the handle B and the shank Q will be determined by the dimensions of the nut which is being rotated, but in any iiistance, the pivot member 8 may be made to traverse the slot 5 tro-in the seat 6 to the seat 'T to bringl the handle 3 more iieai'ly into parallelism with the shank 2 than would otherwise be possible.
The device presents a' tool which possesses at once the advantages incident to disposing the axis of the handle normal to the cooperating faces ot the jaws and to disposing the said axis at an angle to the cooperating taces of said jaws.l
titi
When the pivot member 8 is in the seat 7 as shown in Fig. 2, the jaw l may be tilted forward until the shank 2 of the upper jaw l contacts with that portion of the handle which is disposed between the arms 4., the jaws in such instance being in the position shown in broken line in Fig. 2.
It is obvious that the device may be 0perated in a variety of positions to accommodate the limited space conditions which are incident to the construction of machinery.
