COMBINED HANDSAW AND SCRIBER.

Specification of Letters Patent.

Patented Nov. 21, 1905.

To all whom, it may concern:

Be it known that I, HENRY O. MALIoK. a citizen of the United States, residing at Sunbury, in the county of N orthumberland and State of Pennsylvania, have invented new and useful Improvements in a Combined Handsaw and Scriber, of which the following is a specification.

My invention relates to an attachment for.

handsaws for marking and squaring lumber to be sawed, thus dispensing with a separate square and marker commonly used for that purpose and facilitating work by having the two combined attached to a saw.

The various features of the invention will be hereinafter more fully explained and described in connection with the accompanying drawings, in which Figure 1 is a side view of a saw with my improvement attached, having part of the handle and the shield broken away, showing the-parts. Fig. 2 is a top plan view. Fig. 3 is a section-on line 3 3 of Fig. 1. Fig. 4. is a side view of a modified form of operating mechanism, a part of the saw-handle being shown partly in section and partly in side view.

Referring to Figs. 1, 2, and 3 of the drawings, 1 indicates an ordinary handsaw with a handle 2. On the back edge 3 of the sawis placed a small square or round steel rod 4, running parallel with the back edge 3 and having small markers 5 projecting from either or both sides of the rod. This rod is held in.

position by the shield or guide 15, hereinafter described. The markers 5 may be made of steel or other suitable material, are'pointed at the ends, and. can be made in one piece passing through the rod 4 and projecting at one or both sides of the rod, or they may be made in two pieces and inserted in either or both sides of the rod.

, the center of the saw-handle 2 is a lever 7,

pivoted at 8, one end of which is attached to the rear end of the rod 4: by a pin 9, engaging a slot 9 in the lever, as shown. The other end of the lever is-attached to a rearwardly-extending push-rod 10, by means of a pivot-pin 11. The push-rod 10 has a fingerpiece 12 on its free end within the hand-opening 2 in the saw-handle. Arranged in the opening 6 of the saw-handle is a small spring 18, which is secured to the handle on the one side and to the lever 7 on the other. The ob- In an opening 6 in ject of the spring 13 is to hold the rod 4 normally pressed forward. The front edges 14: of the handle 2 are arranged at right angles to the back edge 3 of the saw and serve as guides to hold the marker at right angles to straight edges of the lumber. The guiding edges 14 are preferably of brass or other metal. A shield 15, made of metal and U shape in cross-section, is so constructed that it can be placed over the back edge of the saw 3 and the rod 1. The flanges 15 of this shield have transverse slots 16 extending upward from their lower edges, so that the shield may be placed in position or removed with out interference with the markers, and these transverse slots intersect longitudinal slots 17 in the flanges through which the markers project when the shield is in position. The longitudinal slots permit the markers to move freely lengthwise of the saw-blade when the rod 1 is reciprocated. The shield is secured to the saw by means of curved projections 18 at one end, which extend into openings 19 in guides 14, and by a pin '20, passing through the shield and saw at the other end. If it is desired to use the saw without the marker attachment and shield, these can readily be removed by withdrawing pins 9 and 20.

Instead of operating the marker by a re ciprocating push-rod pivoted to the lever 7, as above described, the marker may be operated, as shown in Fig. 4:, by a lever 21, mounted on a pivot-pin 22 within the handle. shorter arm 21 of the lever is adapted to bear against the rear side of the shorter arm 7 of the lever 7 when the finger-piece 12 is moved upward, thus drawing the marker backward and compressing the spring, as indicated in full lines. When the finger-piece is moved downward, the arm 21 of the lever 21 swings toward the pivotal point of the lever 7 and passes out of engagement with the latter lever, allowing the spring to move the lever 7 and marker forward, as indicated in dotted lines. By rocking the lever 21 back and forth a few times the points on the marker may be made to mark the lumber in straight lines.

The operation of the device is as follows:

The

The saw-blade 1 is placed on the piece of lumher to be cut with one of the edges or guides 14 resting against and parallel with one edge of the lumber. The saw is placed so that the cut, and by operating the finger-piece the marker will be reciprocated and its points will score the lumber in a straight line. The saw is then used to cut the lumber along this line.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination with a handsaw provided with a transverse straight-edge to serve asa gage, of a longitudinally-reciprocable rod mounted on the back of the saw for longitudinal movement parallel therewith and guides on the back of the saw to'limit and restrain the movement of the said rod.

2. The combination with a handsaw provided with a transverse straight-edge to serve as a gage, of a rod supported for longitudinal movement on the back of the saw and provided with laterally-projecting points adapted to mark the lumber.

3. The combination with a, handsaw. provided with a transverse straight-edge to serve as agage, of a rodsupported for longitudinal movement on the back of the saw and provided with laterally-projecting points adapted to mark the lumber, and means within the sawhandle to reciprocate said rod.

4. The combination with a handsaw provided with a straight-edge at right angles to the back of the saw to serve as a gage, of a scriber mounted on the back of the saw and means within the saw-handle to reciprocate said scriber at right angles to said straightedge.

5. The combination with a handsaw, of a marker, comprising a rod movable longitudinally of the saw-blade and having laterallyprojecting pins or points adapted to mark the lumber, a lever pivoted to the saw-handle and connected to said rod, a spring normally pressing the lever in one direction and means for moving the lever in the opposite direction against the action of the spring.

6. The combination with a handsaw, of a marker, comprising a rod movable longitudinally of the saw-blade and having laterallyprojecting pins or points adapted to mark the lumber, a lever pivoted to the saw-handle and connected to said rod, a spring normally pressing the lever in one direction, and a push-rod for moving the lever in the opposite direction against the action of the spring.

7. The combination with a handsaw, of a U-shaped shield arranged over the back of the saw and having longitudinal slots, a rod arranged within said shield and having pins projecting through said slots, and means for reciprocating said rod.

8. The combination with a handsaw, of a U-shaped shield arranged over the back of the saw-blade,said shield having longitudinal slots and transverse slots intersecting said longitudinal slots, a marker, comprising a rod arranged within the said shield and having pins or points extending through said longitudinal slots, and means for reciprocating said rod.

9. The combination with a handsaw, and a U-shaped shield arranged over the back of the saw, and having longitudinal and transverse slots, said shield also having tongues at its rear end engaging openings in the saw-handle and means for securing the forward end of said shield to the saw-blade, of a rod movable longitudinally between the shield and the back of the saw, said rod having pins or points projecting through said longitudinal slots, and means for reciprocating said rod.

10. The combination with a handsaw, having a transverse guide, of a rod movable longitudinally upon the back of the saw-blade and havinglaterally-projecting pins or points, a lever pivoted to the saw-handle and having one end connected to said rod, a push-rod connected to the opposite end of said lever, a spring interposed between said lever and the saw-handle and means for holding said rod in position upon the back of the saw-blade.

In testimony whereof have signed my name to this specification in the presence of two subscribing Witnesses.

HENRY G. MALIOK.
