FOLDING FRAME SWEDISH TYPE BUCK SAW Film; July 11. 1958 2 Sheets-Sheet 2 INVENTOR. VIRG|L4 DAVID CANFIELD United States FOLDING F SWEDISH TYPE BUCK SAW Virgil David Canfieid, Vashon, Wash. Application July 11, 1958, Serial No. 748,044
1 Claim. (Cl. 145-33 This invention relates to tools and more particularly to a hand saw.
It is an object of the present invention to provide a collapsible Swedish type buck saw which can be used for the same purposes of conventional Swedish type buck saws, but which is readily foldable into a compact transport carrying position for use by hunters, sportsmen and the like.
Another object of the present invention is to provide a foldable Swedish type buck saw having a full size blade that is extremely flexible and easily and safely packed for transport.
Still a further object of the present invention is to provide a buck saw of the above type which is rigid in the normal use position, but which is loosely jointed when in the folded position so as to readily conform to. other articles in a pack used by sportsmen.
Other objects of the invention are to provide a folding frame buck saw bearing the above objects in mind which is of simple construction, has a minimum number of parts, is inexpensive to manufacture and efiicient in operation.
For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in conjunction with the accompanying drawing, in which:
- Figure 1 is a front elevational View of a saw made in accordance with the present invention in an operative position;
Figure 2 is a fragmentary cross sectional view taken along line 22 of Figure 1;
Figure 3 is a transverse cross sectional view taken along line 3-4: of Figure 1;
Figure 4 is an enlarged fragmentary cross sectional view taken along line 4-4 of Figure 1;
Figure 5 is a perspective view of the saw shown in Figure l in a partly folded position;
Figure 6 is an enlarged fragmentary view of certain parts of the invention in operative use.
Referring now more in detail to the drawing, a folding saw 10 made in accordance with the present invention is shown to include a collapsible back her constructed from a pair of back bar sections 12, 13 having adjacent ends partially cut away anglewise to define a V -shape when brought together as shown in Figure 4, is pivotally hinged together at one end by means of a strong plastic strap 16, or the like, attached to mounting rivets 17 on bar sections 12, 13 so as to be readily movable between a normal axially aligned position, as shown in Figure 1, and a completely folded position for convenient portability and/or storage during periods of non-use. Figure 5 illustrates movement of the apparatus toward such a folded position. A sleeve 19 slidably supported upon the back bar sections 12, 13 for longitudinal reciprocating movement releasably locks these sections in the axially aligned position shown in Figure 1 when extended over the joint therebetween. A stop member 18 carried by one back section 12 limits the longitudinal movement of the sleeve 19 in one direction so as to properly'center it over the back sections 112, 13 in the manner illustrated in Figure 1. A pair of U-snaped hinge brackets 22 are pivotally apported upon the opposite ends of the back bar sections 12, 13 by means of transversely extending bolts 23. Each of the hinge plates 22 integrally supports a leg 29, 21 for selective rotation between the extended position shown in Figure l in which they define an included obtuse angle with the longitudinal axis of the back section, and a folded collapsed position as illustrated in Figure 5. The legs are slotted at 24, 25. v i
A lever 26 having a circular end 27 is provided with an upward slanted wing 28 which is slotted at 29 to receive a saw blade 30. Bolts 32 transversely secure the lever 26 to leg 26 and a keeper pin 33 secures the wing of the lever to the saw blade 3h. The opposite end of the saw blade 30 is supported upon a similar keeper pin 34 carried by the otherone of the legs 21. Thus, by placing the saw blade 39 through slots 29, 24, slot 25 and the keeper pins 33 and 34' applied thereto, the handle 26 is in a spaced position relative to the leg 20, rotation of the handle lever 26 to the closed and opened position illustrated in Figure 6 of the drawing is operative to tension the blade 30 because of the relationship of the keeper pins 33, 34 with the lever 25 This structure enables the blade 36 to be readily mounted and dismounted upon the frame as it is moved between the folded and the open position for use.
While various changes may be made in the detail construction, it shall be understood that such changes shall be within the spirit and scope of the present invention as defined by the appended claim.
What 1 claim as new and desire to protect by Letters Patent of the United States is:
A collapsible Swedish type buck saw comprising, in
combination, a foldable back assembly including a pair I of back sections having adjacent ends, a pair of legs,
to an opposite end of said back assembly and including hinge plates integral with one end of each of said legs,
and bolts p-ivotally securing each of said plates to one of said back sections, each plate having a stop portion limiting rotation thereof toward an open position to define an obtuse included angle with said back sections, hinged connection means connecting the adjacent ends of said back assembly and including a strap supported by rivets in said back sections, means selectively locking the adjacent ends of said back sections in rigid axially aligned relationship, a saw blade, positioning means on each one of said legs for supporting one end of said saw blade, and tightening means associated with one of said positioning means for tensioning said saw blade.
