  • FIGS. 1-10 therein illustrated is a hacksaw utilizing the concepts of the present invention and generally comprised of an integrally formed frame generally designated by the numeral 10, a handle generally designated by the numeral 12, a draw bolt assembly generally designated by the numeral 14 and the hacksaw blade generally designated by the numeral 16.
  • this is integrally formed from metal stock with an elongated bridge section 18, a depending outer end section and a depending inner end section 22 whichis best seen in FIG. 8. Adjacent the free end of the outer end section 20, the metal of the frame 10 is deformed so as to extrude or punch-out a transversely extending pin 24 from one side surface thereof.
  • An elongated slot 26 extends inwardly from the free end of the outer end section 20 at a point spaced towards the inner end section 22 from the pin 24 to provide a depending leg 28. In turn this leg 28 is bent to provide an axial offset which defines a channel between its inner surface and the opposing surface of the outer end section 20 about the pin 24.
  • the hacksaw blade 16 may be secured upon the outer end section 20 by seating the pin 24 in an aperture formed at the one end thereof and then pivoting the blade 16 into this channel so that the leg portion 28 will bear against the surface of the hacksaw blade 16 opposite that surface which is bearing upon the surface of the outer end section 20 about the pin 24. This minimizes any tendency for the hacksaw blade 16 to lift-off the pin 24 when the blade 16 is in the operative position.
  • first portion 30 of generally C- shaped configuration which is connected at its upper end to the bridge section 18, and a base portion 32 which is connected to the bottom end of the first portion 30.
  • the base portion 32 in turn includes a reversely bent mounting portion 34 extending laterally from the plane defined by the longitudinal axes of the bridge section 18 and outer and inner end sections 20, 22, respectively.
  • the mounting portion includes a transversely extending mounting arm 36 at the free end of the base portion, an
  • a slot 42 of generally T-shaped configuration extends inwardly from the free end of the mounting arm 36.

At its opposite end the draw bolt 44 is provided with threads 48 on a shank portion of reduced width relative to the head or end from which the pin 46 is formed, and it can be seen that the head is of greater width than the width of the vertically extending portion of the T-slot 42 so as to prevent its being drawn therethrough.
  • the draw bolt 44 also includes a portion of reduced width 50 intermediate the head portion bearing the pin 46 and the shank portion beaing the threads 48 so as to permit its rotation within the slot 42.
  • a washer 52 Seated upon the draw'bolt 44 is a washer 52 which bears against the surface of the mounting arm 36 and a wing nut 54 which is threadably engaged upon the threads 48.
  • the hacksaw blade 16 may be seated upon the draw bearing assembly 14 by extending the pin 46 through the aperture formed adjacent the end thereof and it may then be tensioned by threading the wing nut 54 upon the draw bolt 44 to pull the inner end of the hacksaw blade 16 tightly towards the mounting arm 36.
  • the bridge section 18 of the frame 10 is provided with an aperture 56 adjacent its juncture junctre with the inner end section 22.
  • the handle 12 in turn is fabricated in two halves 58, 60 which have interfitting lips 62, 64 along their mating edges and which are joined together about the bridge section 18 and inner end section 22.
  • the security of the assembly is enhanced by the lug 66 on the handle half 58 which seats in the aperture 56 formed in the bridge section 18.
  • the handle halves 58, 60 have internal ribs and bosses to snugly fit about the bridge section 18 and inner end section 22 to provide a firm assembly, while at the same time minimize the amount of material required for the handle 12.
  • the handle halves 58, 60 are provided with aligned elongated apertures therein which slope upwardly and forwardly to provide the finger receiving aperture 68 with the handle portion 70 forwardly thereof serving as a guard for the users hand.
  • the hacksaw blade 16 may be mounted only in a vertical position with its teeth 72 extending either downwardly or upwardly as desired by the user.
  • the user first mounts the forward end of the blade 16 on the pin 24 with the blade extending generally downwardly from the outer end section 20.
  • the hacksaw blade 16 is then pivoted upwardly into the recess defined by the depending leg portion 28 and the opposite end is snapped over the pin 46 upon the draw bolt assembly 14. Turning the wing nut 54 upon the draw bolt 44 will then tension the hacksaw blade 16 and secure it firmly in position.
  • FIGS. 11-14 this is designed to accommodate the hacksaw blade 16 in either a vertical or a horizontal disposition relative to theplane defined by the principal axes of the bridge section 18 and end sections 20, 22 of the frame 10.
  • the same numerals are employed to designate the equivalent parts as had been employed with respect to the embodiment of FIGS. 1-10 and new numerals will be employed to designate additional or modified elements and features.
  • the outer end section 20 has a depending pin 74 extending from the free end thereof below the transversely extending pin 24 and it is dimensioned and configured to seat in the aperture of the hacksaw blade 16 when it is mounted in the horizontal position shown in FIG. 12.
  • the mounting arm 36 of this embodiment is provided with a complexly configured slot generally designated by the numeral 76 and having a channel portion 78 extending inwardly from the free end thereof into an L-shaped portion provided by a leg portion 80 extending parallel to the free end and a leg portion 82 extending perpendicularly thereto. With the blade 16 in the horizontal disposition shown in FIG. 12, the draw bolt 44 is disposed in the leg portion 82 of the slot 76.
  • the draw bolt 44 When vertical disposition is desired, the draw bolt 44 may be loosened by rotating the wing nut 54 to bring the reduced width portion of the draw bolt 44 into the slot 76 to permit its rotation. The draw bolt 44 may then be rotated so as to dispose it in the leg portion 80. To effect the change in disposition of the hacksaw blade 16, it is necessary initially to disengage the blade 16 from the pin 46 upon the draw bolt 44 and remove it from the pin 74 on the outer end section 20. The hacksaw blade 16 is then mounted upon the pin 24 and pivoted upwardly into the guide channel provided by the leg portion 28 and then snapped over the pin 46 on the draw bolt 44, following which the wing nut 54 is tightened to secure and tension the hacksaw blade 16.
  • the frame is blanked from sheet metal stock and the bends therein are formed after staking of the pin and cutting and stamping of the slots necessary to form the offset leg and the mounting portion.
  • the handle halves are desirably fabricated from synthetic plastic material and may be readily secured about the frame by ultrasonic welding, adhesives or other suitable techniques. Although other materials may be employed, it has been found preferable to utilize hardened steel for the draw bolt and nut so as to insure a rugged structure. It will be appreciated that variations in the illustrated configurations for the several components may be employed without deviating from the basic concepts of the present invention as may be other materials of construction.
  • the hacksaw of the present invention utilizes a relatively simple, economical and rugged frame assembly formed from a minimum of parts and permitting the use of highly durable materials.
