COMBINATION HANDSAW Filed March 31, 1928 2 Sheets-Sheet 1 WITNESS' ATTORNEY April 8,' 1930. I w. J. MORREN 1 v 4,

COMBINATION HANDSAW Fiieduarcn a1, 1928 z sheets-sheet 2 INVENTOR ATTORNEY Patented Apr. 8, 1930 UNITED STATES PATENT OFFICE comma'rron rrmsaw Application filed March 31, 1928. Serial No. 266,372.

This invention relates'to hand-saws, the object being to provide a saw adapted for home use so that a handy man more or less familiar with tools will be enabled to operate i with a sawand hammer so as to perform most of the carpentering operations necessary at his home. A journeyman carpenter carries a tool box containing a great variety of tools including squares, protractor, gauges and a considerable variety of tools which each has its own particular use but makes a comparatively heavy outfit to carry.

It is the object of my invention to provide a single tool which will permit a handy man partly skillful with the use of tools to do a great variety of home work in a workmanlike manner which would ordinarily require the presence and expense of a journeyman carpenter. v

In carrying out my invention I provide a hand-saw in which the back of a blade is secured to the handle at a right angle in the usual way, but I provide the handle containing the saw-blade riveted within a slot with a forwardly projecting wooden or metallic angular projection on each side arranged in the formation of a set of terraces or steps each of which forms a salient projecting angle by which protractor lines may be effected by holding the saw angularly with relation to a piece of timber. This position adapts the saw to be used for a great variety of purposes as in cutting proper angles for forming steps, benches, chairs, various angles for rafters and necessary in carpentering work. I also provide a handle with a flush surface parallel to the saw-blade on which I mount a low circular spirit level which enables the operator to plumb a surface as to its level character.

The characteristic feature of my invention is a slitted handle carrying the saw-blade, the edges of the handle being provided with ledges forming various angles from a right angle 45, and 30, a half-pitch, quarterpitch, etc.

My invention therefore consists of a handsaw having a straight edge blade at the back riveted to a handle the edge of which consists of a plurality of terraces or steps having vaa' great variety of angular cuts which are rious angles on the several ledges for laying.

out carpentering work. It comprises also such a hand-saw provided with an enclosed spirit level mounted on a plane arallel to the saw-blade for lumbing a sur ace.

The several eatures will be more described in the specification accompanying the drawings, and'the novel features will be specifically indicated in the appended claim.

In the accompanying drawings Figure 1 represents a saw embodying my 1mprovements 1 Figure 2 is a top plan view thereof;

Figure 3 represents an application thereof; and

Figures 4, 5, 6 and 7 represent other applications.

Referring now particularly to the drawings, 1 represents a slotted handle of ordinary construction for a hand-saw provided with the usual inclined slot forming a hold for the fingers of the hand. The handle carries a blade 3 of steel one edge of which is provided with sharpened teeth and the other forms a straight edge as indicated by alignment with a vertical post in Fig. 1. The blade may be set in a slot in the usual way and secured by a plurality of rivets to firmly anchor it to the handle. The handle itself may be formed of wood or metal such as soft metal such as aluminum, but according to my invention the slotted part thereof is provided with a protruding angular section formed in step or terrace form as indicated'in Fig. 2. The edges of these steps are at right angles to the face ofthe blade at both sides, each step or terrace rising progressively toward the outer edge of the handle and forming various angles at less than a right-angle as half-pitch 4, thirdpitch 5 and quarter-pitch 6 to form different slopes on the edges of timbers.

I have shown a number of different applications of the invention by which various slopes may be effected by use of the tool and by which timbers may be properly leveled.

against the side of the timber and the line a ong the back of the blade forms a guide for makin the mark on the timber which would be at rlght angles to the longitudinal edge. 5 In Fig. 4 I have shown a mode of leveling: piece of joist or timber. The back of t e saw+blade is laid along the timber and the latter is-shifted until the bubble in the spirit level indicatesa horizontal position when the timber is fixed in place. In Fig. 5 is shown a method of employing the tool for producing a sloping cut suitable for roof rafters. As shown in the upper part of the diagram the saw is placed with the third step alignin 18 with the longitudinal edge of the timber an a line on the timber marked along the back edge of the saw-blade. At the lower edge of the timber the saw is applied reversely with the complementary edge of the ledge 20 bearing against the underside of the rafter and the timber marked as before along the back edge of the saw. thus giving a proper slope forthe setting of the bottom of the timber. A similar method as shown in Fig. 6

' is adapted to form the notched side beams of a pair of stairs producing right angular treads and risers for the steps. In Fig. 7 is shown a method of producing the cuts along mitered angles to form the component joints of back, seat, legs and braces of a chair the wood being marked by applying the several ledges to the same along the several angles indicated in Fig. 1 to eflect the desired slope of the adjoining mitred edges to produce a rigid structure.

It will be apparent from what has been hereinbefore stated, that the tool with terraced ledges on the handle in conjunction with the spirit levelmounted on' a parallel plane to the blade back adapts the saw to a great variety of uses and takes the place of a variety of tools'ordinarily required to accomplish the same result.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 2- A hand-saw having a slotted handle to secure a steel saw-blade the edge of the handle projecting forwardly of the blade upon the opposed faces thereof and shaped to provide a plurality of angular curved terraces rising vertically in staggered relation to form ridges with the blade, the several angles varying from a right angle to a range of a plurality of joiners pitches to adapt the tool to form a varied series of angular cuts. In testimony whereof I afiix my signature.
