14 Claims, 14 Drawing Figures PATENFEDJUL 2 I974 382L974 saw 2 or 3 28 FIG.4' I2 HACKSAW WITH NOVEL BLADE MOUNTING MEANS BACKGROUND OF THE INVENTION Various structures have been proposed and marketed for use as hacksaws, most of which permit mounting of the blade in a vertical position relative to the hacksaw frame and some of which permit mounting of the blade in a horizontal position relative to the frame. In addition, devices have been proposed in which the hacksaw blade is not secured adjacent its outer end but is supported only inwardly from the outer end to provide an unobstructed end portion for operation in areas where there is little clearance.

Various structures have been proposed for providing a frame handle and blade tensioning means. Generally, such structures require a multiplicity of parts and consequent extensive assembly operations. As a result, hacksaw frame assemblies tend to be of relatively high cost if the materials of construction and the quality of fabrication are of first order. There has remained. a need for durable, good quality but economical hacksaw frame assemblies and there has also remained a need to insure both safety and versatility in relatively inexpensive hacksaw frame assemblies.

Accordingly, it is an object of the present invention to provide a novel hacksaw employing a frame assembly with relatively few parts so as to permit economy of construction and facility of assembly.

It is also an object to provide such a hacksaw in which the blade may be pivoted upon the frame for use in either a vertical or a horizontal orientation.

Another object is to provide such a hacksaw in which the guard for the users hand is integrally formed with the handle.

SUMMARY OF THE INVENTION It has now been found that the foregoing and related objects can be readily attained in a hacksaw comprising a frame member integrally formed with an elongated bridge section, an outer end section depending from one end of the bridge section, and an inner end section depending from the other end of the bridge section. The inner end section has a first portion which is connected at one end to the bridge section and depends therefrom and it also has a base portion extending from the other end of the first portion in the direction of the outer end section in spaced relationship to the bridge section. The base portion includes a reversely bent mounting portion which extends laterally from the plane defined by the longitudinal axes of the bridge and end sections to provide a transversely extending mounting arm at its free end and a spacing between the transversely extending mounting arm and the other arm of the reversely bent mounting portion.

Handle means is provided on the inner end section for gripping of the hacksaw, and blade engaging means is provided on the outer end section adjacent the free end thereof for engaging one end of the hacksaw blade. Mounting means is provided on the mounting arm in substantial alignment with the blade engaging means of the outer end section for engaging the other end of the associated hacksaw blade in cooperation with the blade engaging means so as to engage firmly the hacksaw blade therebetween.

In the preferred embodiment, the blade engaging means on the outer end section includes a transversely extending pin projecting from one side surface thereof and adapted to seat in an aperture formed in the associated hacksaw blade. A depending leg. portion is formed at the free end of the outer end section and is laterally offset in the direction of the pin and spaced from the pin towards the inner end section. As a result, this leg portion is adapted to bear upon the side surface of the associated hacksaw blade which is opposite that surface disposed against the surface of the outer end section about the pin so as to retain the end of the hacksaw blade upon the pin. The pin and leg portion are desirably integrally formed in the frame member with the pin being extruded from the material thereof and the leg portion being bent outwardly from the material thereof adjacent the free end of the outer end section.

The mounting means on the mounting arm includes a slot in the mounting arm and a draw bolt assembly seated in the slot, and the draw bolt assembly includes a draw bolt having a pin adapted to seat in an aperture formed adjacent the end of the associated hacksaw blade. In the preferred embodiment the draw bolt is of plate-like cross section with the pin formed adjacent one end thereof and with threads formed adjacent the other end thereof and a portion of reduced cross section intermediate the pin and the threads which may rotate in the slot of the mounting arm. Nut means is threadably engaged on the threads of the draw bolt to effect tensioning'of the associated saw blade.

To permit mounting of the hacksaw blade in horizontal position, the blade engaging means on the outer end section includes a pin projecting from the free end thereof and adapted to seat in the aperture of the associated hacksaw blade, and the mounting means on the mounting arm includes draw bolt means which is pivotally mounted on the mounting arm to permit pivoting thereof. In its preferred aspect, the mounting arm has a slot which extends inwardly from the free end thereof with an L-shaped portion spaced inwardly from the free end, and the draw bolt means includes a draw bolt of plate-like cross section with a portion of reduced cross section intermediate its ends, which is adapted to seat in either one of the legs of the L-shaped portion of the slot.

In its preferred aspect, the handle means is formed with a generally vertically extending aperture therein to receive the fingers of the user and to provide a guard disposed towards the outer end section.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS Turning first to the embodiment of 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.

Turning first in detail to the structure of the hacksaw frame 10, 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. As a result, 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.

Turning now to the inner end section 22 of the frame 10, this includes a 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. As a result of this configuration, the mounting portion includes a transversely extending mounting arm 36 at the free end of the base portion, an

intermediate web portion 38 .and an inner arm 40 spaced from the mounting arm 36 so as to provide a channel therebetween. In this embodiment a slot 42 of generally T-shaped configuration extends inwardly from the free end of the mounting arm 36.

Seated in the slot 42 of the mounting arm 36 is the draw bolt or tensioning bolt assembly 14 which is generally comprised of the plate-like draw bolt 44 which has a pin 46 projecting from one side surface thereof and formed by staking from the metal of the draw bolt. 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. 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. As a result, 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.

As best seen in FIGS. 8 and 9, 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. As seen, 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.

In the utilization of this embodiment, 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. To assemble or change blades, 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.

Turning now to the embodiment of 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. In these figures, 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.

As best seen in FIG. 13, 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.

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.

It will be appreciated that various materials can be utilized for the fabrication of several components. Conveniently, 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.

Thus, it can be seen that 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. The hacksaw blade may be located in position and tensioned fully by a simple but durable assembly. In the one embodiment, the hacksaw blade can be oriented in either vertical or horizontal positions with relative facility and again utilizing a minimum number of parts.
