3 claims. (01; 14s-roti This invention relates to saws, Iand more particularly has reference to an improved handle therefor.

As is well-known, saws are made and sold by a 54 number.' of manufacturers and it is customary to sell the blade 'with a handle attached. The blade invariably wears out before the handle, so that thereis a needless waste when the saw is discarded inasmuch as the handle is usually in good condition and capable of continued use.

Furthermore, the selling of the saw with a handle permanently affixed thereto is a needless expense, for a single handle that could be readily secured and removed from the blade would sufce fora large number of difiere-nt blades, such as cross cuts, rip saws, back saws, etc. n

This extravagance is particularly noticeable when a valuable handle is desirable-that is, a handle that is other than the conventional wooden handle. Therefore, my invention finds particular application in the case of saw handles such as set forth in my copending applications Serial Nos. 681,633'and '740;517, filed July 21, 1933 and August 18, 1934, respectively; although, of course, it will be'readilyvapparent that itfmay be used with a number of different types of handles.

To overcome the objections inhering in the prior art is one of ythe objects of my invention.

Another object of my invention is to provide 30 a saw handle that may be quickly and easily secured to and removed fro-m a saw blade.

Yet a further object of my invention is to provide a saw handle that may be readily attached to saw blades of various kinds and produced by dif- 35 ferent manufacturers.

With these and other objects in View, which may be incident to my improvements, the invention consists in the parts and combinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements comprising my invention may be varied in construction, proportions and arrangements, without departing from the spirit and scope of the appended 45 claims.

In the accompany drawing I have shown one specific embodiment of my invention, but it will of 'course be distinctly understood that various modifications may be made therein without ex- 50 ceeding the scope of the appended claims by which alone I am to be bound.

In the drawing, in which corresponding numerals indicate the same part;

Figure 1 is an elevational view of the handle un- 55 attached to a blade;

Figure 2 is an elevational view of the handle at tach'edto a cross cut blade;

Figure 3 isa sectional view'along" line 3-"-3 of Figure 2;

While I have showii'in the drawing ahandle "of more or less conventional construction except for the means for attaching the'ls'ame to al blade,V it will be apparent that Variousl types of handles may be employedand as a matter of fact, the iny u ventionl findsV particular application, as above l0 pointed out, to handles morek eip'ensiv tha-nth usual wooden handles:

The handle shown in Figure 1, designated generally by the numeral l, is made up' of a grip enf gaging portion 2 and a blade receiving prtion. 15 The blade-receiving portion 3 is slotted as at 4 in Figure 3.

Within this sloty 4 the blade 5 is inserted. While theblade 5 is shown as being of thecro's's cut type,r it will of course be appreciated that a rip saw, a back saw blade, and various other types of blades may be inserted.

The exposedY side ofthe blade'receivingportion 3fis recessed as at as best shown in FigureY 3; y, A coping 'l may surround the recessed-portion for 25' the purpose of reinforcing it.

Drilled through both of the recessed portions 6 are a plurality of apertures 8 which are preferably aligned as sho-wn in Figure 1, but which may be otherwise disposed. For a purpose which will now be described, there should be a relatively large number of such apertures which may be spaced in accordance with apertures in the various types of saw blades with which the handle may be used.

As is well known, saws of the prio-r art have blades which are drilled with holes registering with holes in the saw handle, and through these holes rivets, bolts, or other means are inserted for the purpose of securing the blade and handle together. For purposes of illustration, I have shown the blade 5 depicted in the drawing as being provided with two such apertures, although the number of apertures may Vary. The blade 5 represents. a standard blade made by some typical manufacturer.

Another manufacturer may produce a blade which has a different number of apertures, or apertures which are otherwise disposed. In any event, all saw blades are provided with some forms of apertures, such as aperture 9 shown in 50 Figure 3.

After the blade is arranged in the slot 4 of the handle so that its apertures register with some of lthe apertures 8 of the handle, I preferably use a 'i handle together. It Vwill be appreciated that the bolt Il may be readily inserted through the registering apertures and the wing nut I2 enthreaded thereon. Y Y

For the purpose of illustration, the letters in the apertures of Figures l and 2 areV merely to designate the apertures of blades of di'iferent man-f ufacturers and to show how they will register. Y

For instance, the apertures in'which the letter A A manufacturer.

. I2 screwed thereon.

appear are those apertures WhichY will register with the apertures inblades manufactured by The letter D represents the aperturesfor the blades manufactured .by D manufacturergand so on.

It will also be appreciated that diierent types j of blades, such as rip, cross out, back, etc.-even though produced by the same manufacturer, may have a diierent dispositionl of the apertures in the blade. This, of course, will also be takencare When it is desired to use a different blade for any purpose whatsoever-that is, because the present blade is dulled, worn out,V or because it is Vdesired to use a different type of Ablade-it is merely necessary to remove the Wing nut I2Y and the bolt IVI and replace the blade then in the handle with the desired blade.

It will be appreciated that my invention has decided advantages over the prior art. In the first place,'the handle may be economically manufactured, and an appreciable Vsaving may be eil'ected by usinga single handle for'amultiplicity of saws. The joining of the blades and handle may be readily effected, and, when done, the blade is securely held in the handle. The removal of theV blade from the handle, when desired, is also readily accomplished.

While I have shown and described the preferred embodiment of my invention, I Wish it to be of uncise details of construction herein set forth by Way of illustration, as it is apparent that many changes and variations may be made therein, by
