2 Claims. (Cl. 145-33) This invention pertains to collapsible saws, and relates particularly to a novel saw construction by which the saw is rendered collapsible to minimum size for convenient carriage.

It is generally recognized among hunters of large game food, such as 'deer and elk, that the flavor and texture of meat is best preserved by quartering the animal as soon as possible after the kill. This requires the use of a meat saw, and since such implements provided heretofore have not been capable of being collapsed to convenient size for carriage upon the person, the quartering operation most often is delayed detrimentally until the animal has been removed from the hunting grounds to a location where conventional meat-cutting implements are available.

It is a principal object of the present invention to provide a meat-cutting saw which may be collapsed to sufficiently small compass as to be carried conveniently within the pocket.

Another important object of this invention is the provision of a collapsible meat saw which is capable of com plete disassembly for rapid and thorough cleansing.

A further important object of the present invention is the provision of a collapsible saw which is capable of assembly and disassembly with speed and facility, and which is of simplified construction for economical manufacture.

The foregoing and other objects and advantages of this invention will appear from the following detailed description, taken in connection with the accompanying drawing, in which:

Figure l is a view in side elevation of a collapsible saw embodying the features of the present invention;

Figure 2 is a sectional view taken along the line 2-2 in Figure 1;

Figure 3 is a sectional view taken along the line 33 in Figure 1; and

Figure 4 is an exploded view in side elevation showing the several parts of the saw in disassembled condition.

Referring to the drawing, the collapsible saw of the present invention is constructed to accommodate commercially available standard types of saw blades, such as the meat saw blade 10, which is provided at its opposite ends with pins 12, 14 which project laterally from the opposite sides of the blade.

The saw blade is supported releasably in a collapsible saw frame which comprises the pair of brace sections 16 and 18 adapted to be connected together in longitudinal extension by means of sleeve 20. The frame also includes a handle section 22 and a blade tightening element 24.

The brace section 16 is provided at its forward end with a transverse notch 26 adapted to receive therein the transverse pin 12 and with a longitudinal groove 28 proportioned to receive therein the forward end of blade 10.

The sleeve 20 is provided with a longitudinal opening 30 having the same contour as the cross section of the 'Z 2,781,806 Ice Patented Feb. 19, 1957 braces 16 and 18, whereby to receive said brace sections therein.

The handle 22 is provided at one end with a longitudinal groove 32 proportioned toreceivetherein the rearward end of brace section 18. A connecting pin 34 projects laterally from the opposite sides of the brace section 1-8 adjacent the rearward end of the latter for engagernent in the offset slot 36 which extends transversely through the section of the handle carrying the groove 32. The groove 36 is offset rearwardly to provide the locking section 38 which functions to secure the rearward end of brace section 18 to the handle 22.

The opposite end of the handle is also provided with a longitudinal groove 40 proportioned to receive slidably therein the blade-tightening element 24. This element includes a flat section which is provided at its forward end with a longitudinal groove 42 proportioned to receive therein the rearward end of blade 10, and a transverse slot 44 adapted to receive the pin 14. Extending rearwardly from the flat section of the tightening element 24 is a threaded projection 46 adapted to receive the wing nut 48. As best illustrated in Figure l, the rearward edge of handle 22 adjacent the longitudinal groove 40 is contoured to provide a flat surface for abutment by the wing-nut 48, the surface being substantially perpendicular to the longitudinal axis of the blade 10.

In assembling the elements of the saw, the brace sections 16, 18 are fitted together within the sleeve 20, and the section 18 is connected to the handle by engaging the transverse pin 34 within the offset locking slot 36, 38.

The tightening element 24 is then inserted in the longitudinal groove 4% at the opposite end of the handle and the opposite ends of the blade 10 are secured to the saw I frame by engaging pin 12 in notch 26 and pin 14 in slot 44. The wing nut is then tightened to tension the blade. This tightening action tends to buckle the brace sections 16, 18 outwardly, whereby they are caused to bind within the sleeve 26. in this manner the sleeve is secured against longitudinal displacement.

The reverse procedure is employed for disassembling the elements of the saw, as will be apparent. The elements of the saw frame may then be collected together in a package of minimum size and the blade may be doubled upon itself to accommodate its inclusion in the package. Although various types of packages may be employed, it is preferred that the elements of the saw be contained within a pounch or wrapper made of cloth or other suitable flexible material. The package is of such minimum size as to be carried conveniently in the 50 pocket.

s It will be apparent to those skilled in the art that various changes in the structural details described hereinbefore may be made without departing from the scope and spirit of the present invention. For example, al-

though the construction has been illustrated in connection with a meat saw blade, it will be apparent that blades designed for other cutting operations may be used with the saw frame, if desired. The number of brace sections may be increased from the two illustrated, if

it is desired to reduce the length of each section. The brace sections may be connected together pivotally rather than detachably, as illustrated, it being required only that the brace sections be capable of being reduced from their extended length to accommodate packaging.

The detachable connection between the handle and brace may be made in various ways, well-known to those skilled in the art.

Since the foregoing and other modifications may be made, it is to be understood that the foregoing descrip- 7 tion is primarily illustrative of the invention and is not to be considered as limiting the scope thereof.

Having now described my invention and the manner in which the same may be used, what I claim as new and desire to secure by Letters Patent is:

1. A collapsible saw, comprising a saw blade member, a handle member having a longitudinal groove and a transverse locking slot in one of its ends, a brace member including at least a pair of elongated sections, securing means to selectively secure said sections together in longitudinal extension or render said brace member collapsible to reduced length, one end of the brace member being receivable within the longitudinal groove in the 10 leasable engagement, respectively, in the transverse notch and the transverse slot in the tensioning member.

2. The collapsible saw of claim 1 wherein said securing means comprises a sleeve member and the latter is retained in position by the outward buckling of the brace sections as the tensioning member is tightened.
