Definitions

  • This invention relates to portable impact tools and particularly concerns hammers and similar tools having handles forged of solid steel.
  • a primary object of the invention is to provide an improved impact tool such as a hammer of the type having a handle forged of solid steel and which is capable of withstanding the roughest usage and yet maintaining a tight connection between its handle and the hammer head.
  • Another object of the invention is to provide an improved impact tool of the type described having a steel head forged separately of its solid steel handle and which is adapted to be assembled to provide a durable nonfused connection having good shock absorbing characteristics. Included in this object is the aim of reducing the operational steps and the manufacturing cost required to produce a finished hammer of the type having a solid steel handle.
  • FIG. 1 is a side view, partly broken away, of a hammer incorporating the invention
  • FIG. 2 is a longitudinal view of a handle constructed in accordance with the invention.
  • FIG. 3 is an enlarged fragmentary section view of the hammer taken along line 3-3 of FIG. 1;
  • FIG. 4 is an enlarged transverse section view of the handle taken along line 44 of FIG. 1;
  • FIG. 5 is an enlarged transverse section view of the handle taken along line 5-5 of FIG. 1 with its sheath omitted for clarity of illustration.
  • FIGS. 15 illustrate a preferred embodiment of the invention as applied to a claw hammer generally comprising a metallic head and an elongated handle 12.
  • the head 10 is of conventional construction having an impact end 16 and a claw end 18. Between the impact and claw ends 16 and 16 is an elongated eye 20 which extends into the head 10 from an entrance end 21 of the eye, generally perpendicular to the longitudinal axis of the head 10. As shown, the eye 26 is relatively deep and terminates somewhat short of extending completely through the head 10 to provide a closed inner end 22 for the eye 20.
  • the eye 20 is of uniform circular cross section from end-to-end forming a substantially smooth inner wall surface 24.
  • the head 10 is forged and then machined to provide the above described structure.
  • the handle 12 is solid steel. To minimize the number of manufacturing operations and the cost required to produce a finished assembly, the entire handle 12 is forged separately from the head and then conjoined to the head as described more specifically below.
  • the elongated handle 12 is generally rectangular with a relatively long grip portion 26 forming one of its ends.
  • the grip portion 26 includes a thin flat web section 28 having marginal ribs 30 on its lower end and sides de fining enlarged edges such that a transverse section of the grip portion is generally in the form of an I beam as seen in FIG. 5.
  • a plurality of'aligned apertures 3.2 are formed in longitudinally spaced relation in the web section 28 of the grip portion 26.
  • a longitudinal rib 36 is formed on each face of the web section 28 with the individual ribs 36 respectively extending alongside opposite side edges of the grip portion 26.
  • a sheath 38 preferably formed of rubber, is permanently bonded by a suitable adhesive to the grip portion 26.
  • the outer surface of the sheath 38 tapers inward as indicated at 39 to merge into the contourof an enlargement 40 formed between opposite ends of the handle 12.
  • the enlargement 4t defines the upper end of the grip portion 26 and the lower end of an adjacent intermediate portion 42 of the handle 12, portions 26 and 42 having side edges in continuation with one another.
  • the intermediate portion 42 includes a pair of opposed faces 44 and 46 which smoothly curve inward toward one another from the enlargement 40 and then gradually diverge at the upper end of the intermediate portion 42.
  • the faces 44, 46 respectively merge into an enlarged flange 48 adjacent the end of the handle 12.
  • raised surfaces 49 may be provided on the faces 44, 46 to receive impressions of suitable indicia.
  • the flange 48 defines a relatively short end portion 50 at the top of the handle 12 which is designed to be fitted into the eye 20 of the head 10.
  • the flange 48 and the end portion 50 preferably are both of circular cross section.
  • the end portion 50 is of smaller diameter than the flange 48 which is formed with an annular shoulder 52 extending around the lower end of portion 50.
  • end portion 50 is provided with a wall 54 formed by an elongated hole 56 axially extending into the end portion 50 of the handle 12.
  • the hole 56 is preferably of circular transverse section and the wall 54 is in concentric rela tion to the longitudinal axis of the handle 12 to form a uniform wall thickness.
  • the hole 56 has a reduced inner portion 60 forming a conically shaped surface which is illustrated as being inclined inwardly to terminate in the plane of the annular shoulder 52 of the flange 48 which defines the lower end of portion 50.
  • the end portion 50 of the handle 12 is forced with a press fit into the eye 20 of the head to bottom the annular shoulder 52 of the handle against the head 10 with a slight clearance being provided between the closed end 22 of the eye 20 and the top of the handle end portion 50. Interference resulting from a diiference in the order of 4 to 10 mils in the diameters between the handle end portion 50 and the eye 20 of the head has been found to work satisfactorily.
  • the exterior surface 62 of the wall 54 therefore directly engages the inner wall surface 24 of the eye 20 throughout the extent of their opposed surfaces, and the top outer edge of the end portion 50 is chamfered as shown at 64 to facilitate the assembly of the hammer whereby the head and handle are firmly secured with the end portion 50 under a compressive force.
  • wall 54 is sufficiently resilient to assure that neither the end por tion 50 of the handle 12 nor the portion of the head surrounding its eye will be stressed beyond their elastic limits.
  • an end portion 50 having a wall 54 with a uniform thickness in the order of 0.095 inch produces goOd results.
  • the resiliency of the wall 54 virtually eliminates any tendency of the eye 20 to gradually become enlarged or permanently deformed upon repeated impact and thereby result in the handle separating from the head as would occur, e.g., if the handle were to be formed with a solid end portion connected to the hammer head.
  • the hammer construction of this invention is particularly suited for economical manufacture and assembly in addition to providing a properly balanced hammer giving a natural feeling to the hands of a user. Moreover, a tight head-to-handle connection is featured which assures dimensional stability of the assembled parts despite repeated rough usage.
  • a hammer and the like comprising an impact head having an eye extending into the head, the eye having an entrance intermediate the ends of the head, and an elongated solid steel handle having a hole extending axially into one end thereof and forming a resilient inwardly compressible end portion of the handle fitted into the eye of the head with an interference fit.
  • a claw hammer comprising a metallic head having an impact end and an opposite claw end, the head having intermediate its ends an eye of circular cross section extending from an entrance of the eye into the head in generally perpendicular relation to its longitudinal axis, and an elongated solid steel handle having one end portion inserted with a press fit into the eye of the head, the handle having a hole extending axially into its one end portion and forming a resilient inwardly compressible wall, the wall directly engaging the head in surface-tosurface contact from the entrance of the eye substantially throughout the depth thereof, and the hole extending into the one end portion of the handle having a terminal portion of reduced size in the region of the entrance of the eye providing a relatively incompressible base of increased wall thickness for the one end portion of the handle.
  • a hammer and the like including a work engaging head having an eye extending into the head from an entrance of the eye intermediate the ends of the head, and an elongated solid steel handle having one end portion fitted into the eye, the improvement which comprises the handle having a hole extending axially into its one end portion and terminating in the region of the entrance of the eye to form a resilient wall within the eye of the head, the wall of the one end portion of the handle being under compression and inwardly deflectable to prevent the eye of the work engaging head from becoming enlarged and to firmly maintain the head and the handle in secured relation.
  • the solid steel handle includes intermediate its ends a flange of enlarged cross section bottomed in direct engagement against a portion of the head surrounding the entrance of the eye, and the flange having a shoulder portion rounded inward and merging with the wall of the one end portion of the handle.
  • the solid steel handle includes a grip portion at its end opposite the one end portion of the handle, the grip portion having transverse apertures formed therein thereby to dampen vibrational stresses transmitted through the handle and to balance the same.
  • the one end portion of the solid steel handle includes a concave interior wall surface in the region of the entrance of the eye providing an arcuate juncture between the wall and its base inside the one end portion of the handle.
