Definitions

  • An object of the invention is to provide a hand tool having an improved inter-changeable head feature.
  • a further object is to provide a hand tool having a head which can be removed and replaced in a minimum of time and without the necessity for removing or changing fasteners such as screws.
  • a further object is to provide a hand tool having an interchangeable head including a reciprocable ram and in which the ram is precisely guided along its path of reci rocation.
  • a hand tool comprising a body portion and a head.
  • the body portion comprises a pair of spaced-apart plates and the head portion comprises a frame which extends between these plates.
  • the actuator comprises a pin disposed bet-ween the plates of the body portion which is reciprocable along a rectilinear path and which may include any suitable power means such as a motor or a piston cylinder.
  • the head portion includes a ram having a hook on its end which is adapted to engage the pin.
  • the head is contained between the plates by two interengaging means, one of these interengaging means comprises a pin and notch on one side of the head and the other interengaging means comprising a latch on the other side. The arrangement is such that the head can be removed by disengaging the latch and moving the head laterally from between the plates.
  • FIGURE 1 is a side view of one form of hand tool in accordance with the invention having parts broken away to show the manner in which the head is mounted in the body portion of the tool;
  • FIGURE 2 is a fragmentary view similar to FIGURE 1 but showing the manner in which the head can be removed from the body portion;
  • FIGURE 3 is a view taken along the lines 3-3 of FIGURE 1.
  • Tools of this type comprise a pistol-grip type handle 4 on which there is mounted an electrical motor 6.
  • This motor drives a motion translation mechanism which includes a toggle means having an arm 12 on the end of which there is provided a reciprocable pin 14.
  • a toggle means having an arm 12 on the end of which there is provided a reciprocable pin 14.
  • the present invention is generally directed to a replaceable tool head 18 having a ram which is connected to the pin 14.
  • the head 18 comprises a C-shaped frame member 20, the right-hand end portion 22 which extends between the plates 8, 10 of the tool body.
  • a ram 24 is slidably mounted in this portion 22 of the frame and has, in the disclosed embodiment, the crimping die 26 on its end which is cooperable with a fixed crimping die 28 mounted on the arm 30 of the frame.
  • any alternative type of tooling can be provided on the ram. It should be mentioned, for reasons which will be explained below, that tools of the type shown are nonreversible. Thus, if the motor is energized and the ram 24 starts to move towards the arm 30, the ram must travel to the limit of its leftward movement before it will return to its starting position.
  • the head 20 is secured to the body portion of the tool by means of a pair of notches 32, 36 on opposite sides of the frame and facing in opposite directions.
  • the notch 32 which faces downwardly in the disclosed embodiment is adapted to receive a pin 34 that extends between, and is secured to, side plates 8, 10.
  • the notch 36 which faces upwardly is adapted to receive a tooth 38 on the end of a latch arm 411.
  • This latch arm has bearing boss portions 44 on its underside through which extends a pin 50'. This pin extends between, and has its ends mounted in, the side plates 8, 10.
  • the ram 24 has a notch 51 at its inner end which faces downwardly as viewed in the drawing, as does the notch 32, and which extends partially around the pin .14- on the end of the lever 12. It will be apparent that reciprocatory motion of the pin 14 will be transmitted to the ram 24 when the parts are engaged as in FIGURE 1.
  • the head 18 can thus be removed from the tool by a series of very simple manipulative operations and a different head can be placed in the tool by an equally simple series of operations.
  • the head itself, nonetheless, can be precise and exact so that the dies 26, 28 or their equivalents will be precisely mounted towards and away from each other.
  • the tool shown is non-reversible which means that if a jam should occur, it would ordinarily be impossible to clear the tool without disassembling it.
  • a jam might occur, for example, if a solid piece of metal (rather than a crimpable connector) were to be placed between the dies 26, 28 and the motor were to be energized to move the -die tightly against the solid bar. The ram would then be prevented from traveling to the leftward limit of its stroke and could not be returned to its starting position.
  • a set screw 41 is provided in the latch arm 40. The lower end of this set screw is normally substantially flush with the lower surface of the tooth 38.
  • a tool comprising a body portion and a replaceable head, said body portion comprising a pair of spaced-apart plates, reciprocable actuator means contained between said plates, said head comprising a frame and ram means slidably mounted in said frame, said frame extending between said plates, said ram means and said actuator means being reciprocable along a predetermined path, a first interengaging means on said ram means and said actuator means, a second interengaging means on said frame and said body portion, said first and second interengaging means each comprising a notch and a pin, said notches facing in a common lateral direction with respect to said path, said interengaging means being disengageable upon relative movement of said head away from said body portion in a lateral direction which is opposite to said common lateral direction whereby said head can be removed from said body portion upon movement of said head in said opposite lateral direction.
  • said first interengaging means is on one side of said body portion and including latch means on the other side of said body portion, said latch means comprising a latch notch in said head having its open side facing in said opposite lateral direction and said latch means further comprising a pivoted latch arm on said body portion, said latch arm being adapted to enter said latch notch.
  • a hand tool comprising, a body portion and a replaceable head, said body portion comprising a pair of spaced-apart plates, a reciprocable actuator contained between said plates, said head comprising a frame and a ram slidably mounted in said frame, said frame having end portions extending between said plates, said ram and said actuator being reciprocable along a predetermined path, a first interengaging means on said ram and said actuator, a second interengaging means on said frame and said body portion, said first and second interengaging means comprising open-sided notches on said ram and frame and pins on said actuator and said tool body portion, said pins extending between said plates and the open sides of said notches facing in a common lateral direction relative to said path, said second interengaging means being located on one side of said body portion and frame, and a latch means on the other side of said body portion and frame, said latch means comprising a latch notch on said frame and a latch arm on said body portion, said notch facing laterally in the direction opposite to said common common
  • a device as set forth in claim 3 including a jack screw in said latch arm located to bear against said latch notch whereby, said latch arm can be disengaged from said latch notch when said tool is jammed.
