Specification of Letters Patent.
Patented Nov. '20, 1906'.
A li ti fil d November 24,1905. Serial No. 288,830.
To all whom it may concern:
Be it known that I, OSCAR F. GI-FFIN, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented ce r tain new and useful Improvements in Handsaw-Guides, of which the following is a specification.
This invention relates to improvements in handsawguides, the object. of the invention being to provide an instrument by means of which a handsaw may be guided over a piece of wood to saw the same at any angle to its general direction or many desired plane or inclination to the vertical.
In the accompanying drawings, Figure 1 is a plan view of the instrument. Fig. 2 is a side view thereof. Fig. 3 is a front view. Fig. 4 is a view of the side opposite to that shown in Fig. 2. Fig. 5 is an enlarged detail vertical section through the main pivot of the instrument.' Fig. 6 is a horizontal sec tion on the line 6 6 of Fig. 5.
Referring to the drawings, 1 represents an angular base having a vertical member 2, adapted to rest against the vertical edge of the board, beam, or other piece of wood to be sawed, and a horizontal member 3, adapted to rest upon the top thereof. Pivoted upon a bolt 4, extending upward from the end of said angular base 1, is a horizontal guidesupporting plate 5, onto which is secured a semicircular rack 6. This rack is graduated in angles, each tooth of the rack preferably corresponding with a small number of degrees of arc, as five degrees. Upon the horizontal member of the angular piece 1 is slidably mounted a locking-bar 7, normally pressed toward said rack by a spring 8, and
aving at its end near the rack teeth 9, which are adapted to engage the teeth of the rack.
Hinged to said guide-supporting plate 5, as shown at 10, is an upwardly-extending guide-plate 1 1, on which, in line with the bolt 4 of the plate 5, is a pivot 12'of a semicircular graduated brace 13, which passes through a slot 14 in the angular base and is clamped at any desired point by a set-screw 15. This brace is graduated, as shown at 16, to indi cate the angle of inclination of said guideplate 11 to the vertical. Upon the back of said guide-plate 11 is secured a guide-strip 17, which extends first upwardly and then downwardly over the upper edge of the guideplate 11. The saw is reoiprocated between the guide-strip 17 and the guide-plate 11, the instrument having been set at the desired angle of inclination either across the piece of wood by means of the rack and sliding locking-bar or to the vertical by means of the graduated limb and set-screw.
A cheaper instrument, which suffices for many purposes of carpentry, may be made by omitting the angular adjustment to the vertical of the upwardly-extending guideplate and using only the semicircular rack and locking-bar to vary the inclination of the out across the piece of wood which is to be sawed.
I claim- 1. In combination, a suitable supportingplate adapted to rest upon the piece of wood to be sawed, a guide-supporting plate, one of said plates having immovably secured thereto a bar pivoted to the other plate, said plates and bar all extending from a common center, and said plates tapering toward said center, and having their under surfaces in substantially the same plane, and a guideplate hinged to said guide-supporting plate, and provided with means for guiding a saw in its movement in contact with said plate, substantially as described. 7
2. In combination, a guide supporting plate, a suitable supporting-plate adapted to rest upon the piece of wood to be sawed, having inimovably secured thereto a bar pivoted to the other plate, said plates and bars all extending from a common center, and said plates tapering toward said center, and having their under surfaces in substantially the same plane, and a guide-plate hinged to said guide-supporting plate, and provided with means for guiding a saw in its movement in contact with said plate, substantially as described.
3. Inv combination, a suitable supportingplate adapted to rest upon the piece of wood to be sawed, a guide-supporting plate, one of said plates having immovably secured thereto a bar pivoted to the other plate, said plates and bar all extending from a common center, and said plates tapering toward said center, and having their under surfaces in substantially the same plane, and a guide-plate hinged to said guide-supporting plate, and
provided with means for guiding a saw in its movement in contact with said plate, said means comprising a double U-shaped bar the ends of which are secured upon the side of the guide-plate opposite to the Saw, While the cenctlral portion extenlds lovfir the face of thg gui elatea ainstw ie t esaW moves an in clos proxiinity thereto, the front member GIFFIN' of said piece being shorter than the rear Witnesses: member, substantially as described.

In Witness whereof I have hereunto set my ANNIE PETERSON.
