GUSTAF Y. ANDERSON, OF DYEA, ALASKA TERRITORY.

COMBINED SAW JOINTER AND GAGR.

SPECIFICATION forming part of Letters Patent No. 663,322, dated. December 4:, 1900.

Application filed July 20,1899- Serial No. 724,519. (No model.)

To all whom it may concern.-

Beitknown that LGUsTAF Y. ANDERSON, a citizen of the United States, residing at Dyea, in the Territory of Alaska, have invented a certain new and useful Combined Saw Jointer and Gage, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to combined saw jointers and gages by which crosscut-saws can be more easily and properly filed.

One object of the invention is to provide a device of this character that will permit of the gage-plate being independently, quickly, accurately, and reliably adjusted and firmly held, whereby the former adjustment will serve as a valuable guide in readj usting the gage-plate.

A further object of the invention is to provide the overhanging parts which rest on the saw-teeth points with a smooth and hardened surface to avoid the injurious effects caused by these heretofore rough parts and the friction generally produced while gaging the ra'kers.

A still further. object of the invention is to have the overhanging parts dressed and made smooth throughout their entire inner sides and connected with the frame or body at their extreme outer and inner ends to form a clear, distinct, unbroken longitudinal surface and open spaces opposite the cuttingteeth, through which the points of the teeth can be clearly viewed on a level with the inner side of said overhanging parts, thus providing a straight-edge by which the uniform height of the saw-teeth can be easily ascertained and determined.

A still further object of the invention is to provide a saw-jointer of such construction as to enable the file-clamp to be centrally held in close contact with the frame for preventing wabbling and to hold the file in true position when in use.

The invention consists in certain novel features and details of construction and arrangement of parts, as hereinafter fully set forth, illustrated in the drawings, and pointed out in the claims.

In the drawings forminga part of this specification, Figure 1 is a perspective view of an implement for fitting up crosscut-saws constructed in accordance with my invention. Fig. 2 is an elevation looking at the other side of the implement. Fig. 3 is a sectional view on the line m azof Fig. 2. Fig. 4 isasect-ional view on the line y y of Fig. 2. Fig. 5 is an edge view. Fig.6 is a sectional view showing a modification of the invention. Fig. 7 is a side elevation of the central portion of the implement. Fig. 8 is a central cross-section on the line 2 a of Fig. '7.

Similar characters designate corresponding parts in the different figures of the drawings.

In carrying out my invention I cast or otherwise form the frame of the body 1 of openwork to reduce the Weight of the implement, and at opposite sides of this body are formed projecting

flanges

2 and 3, the lower flanges 3 being partly cut away, so as to still further reduce the weight of the implement. The central portion of the frame is enlarged to form a gage-post 4, which extends a short dist-ance above the top flange 2 and in which is a round, preferably drilled, opening 5, that extends to within a short distance of the lower end of sa d post.

Upon the flange 2 are formed

posts

6 and 7, the latter being at the ends of the frame,while posts 6 are at intermediate points. The tops of said posts are all in exact longitudinal alinement and form seats for the straight-edge sections. Extending from each of the outer posts 7 to the adjoining post 6 is a straightedge section 8, said sections being secured to the posts by machine-screws, which are let into the same through the straight-edge sections, said sections being of hardened steel, smooth and polished throughout on their entire inner surface, so as to leave clear unobstructed spaces under the plates or sections by which the teeth can be clearly viewed on a level with the inner sides of the overhanging plates or sections for ascertaining and determining the uniform height of the teeth.

It may be here stated that While the plates or straight-edge sections might be made integral with the frame and dressed off to suit requirements separate plates are preferable to more easily obtain the several objects in view, and by placing a thin piece of metal between the plates and each of the inner posts of exactly the same thickness and by the further use ofpaper said plates can be adjusted to fit the curve of the saw, so as to rest evenly on the saw-teeth points, and when this is not done a small space should occur between the outer teeth and the straight-edge when the teeth are properlyjointed, as shown in Fig. 2, owing to the curve in the saw, as will be readily understood.

In connection withthe sectional straightedge hereinbefore described between the intermediate posts 6 is located a gage-plate 10, having the usual slot 11 therein, said gageplate being provided with a shank 12, which passes partly through the opening 5 in the gage-post. The shank being of considerable length will permit the lower end to be engaged by an adjusting-screw 13, having a head 14:

and adjoining collar 15, said adjusting-screw brace guide-flanges 18, formed on the posts 6.

The adjustment of the slotted gage-plate is held by means of a set-screw 19 passing through a screw-threaded perforation in lug 20 and engaging the shank in the gage-post.

On the side of the implement shown in Fig. 1 is located the jointer and side file. The dotted line a shows the position of the file as held for jointing the points of the saw-teeth, and the dotted line b shows the position of the side file as held for dressing the sides of the saw-teeth points. On one side of the posts 7 are formed projections 21, on which a part of the seats for the plates 8 extend, and said projections are provided with true bearings at right angles with the outer edges of

flanges

2 and 3. A cylindrical and centrallylocated lug 20 projects laterally from the frame and has a horizontal threaded opening therein, and beneath said lug in one form of the device is another lug 33, having a vertical screw-threaded opening for a screw 32, adapted to operate a file-clamp 22. Said clamp has a longitudinal slot divided by a cross bar or brace 24, and the lower end of the clamp has a notch on the inner side to perwit it to rest closely against the frame when placed over the lugs and screw andis also provided with rightangular projections at each end and a bearing-face 23 at the top, and another bearing against which a cam 25, revolving on the cylindrical lug 20, will contact for operating said clamp. Thus it will be seen that the file-clamp may be operated either with a cam or a screw and that either 3 end of said screw might be made to operate against the clamp, as shown in Fig. 1. It will, however, be understood that both modes of operation are not required in the same tool or combination of tools. The height of the lug 20 should correspond with the thickness of the file-clamp, as shown in Fig. 8, or with the combined thickness of the clamp and the cam, as shown in Figs. 4 and 6, which depends on the mode adopted. A washer 26is preferably used between the lug and the head of the binding-screw 19, which washer has a larger circumference than the lug, the hinding-screw being of the right length to permitthis. The clamp and the cam are placed between the frame and the Washer, the lug passing through the same, and the clamp is held as close against the frame as its sliding movement for securing and releasing the file will permit by the thickness of the washer employed, and thus prevents wabbling of the clamp. Two small guide-flanges 27 have also been provided to further hold the clamp in place, as shown in Fig. 1. By placing the file between the hearings on projections 21 and bearing-face 23 on the top of the clamp, as shown in Fig. 1, and pressing on the lower end of said clamp and turning the cam,which has an oflfset on which to place the finger, a long and even curve in the file can be obtained, the resiliency of the file holding the adjustment. The file will not come in 'contact with the cam, and thereby injure it, and is held true right angularly with the outer edges of

flanges

2 and 3, which will bear against the saw-blade while manipulating the device. This mode of operation is very convenient, and the cam revolving on a laterallyprojecting lug on the frame will not loosen the screw by which it and the adjustment of the gage-plate is held.

By having the usual vertical flanges 28 near the ends of the frame partly cut away, so as to form a recess for the file and a rightangular projection on the lower end of the clamp, the side file for removing the featheredge or burs from the side of the saw-teeth points can be fastened in the same manne as that hereinbefore described.

The form illustrated in Fig. 6 is substantially the same as that hereinbefore described, except that instead of the groove or recess 16 it has a screw-threaded perforation 30in the lower end of the gage-post connecting with the opening 5, the plain adjusting-screw 31 being placed in the screw-threaded perforation and turned until it abuts squarelyup against the end of the shank. By pressing with the finger on the gage-plate while adjusting the same the gage-plate can be quickly and fully as accurately adjusted as in the construction of the implement whereby the screw having the collar is used.

By reference to Figs. 7 and 8, it will be seen that in this form the cam 25 is omitted and the screw 32 and lug 33 adopted. The file-clamp 22 is of the same form and holds the file in both positions and is itself held against the frame in the same manner as has been hereinbefore described.

From the foregoing description it will be ITO noted that I provide a tool adapted to a variety of purposes il'idepex'ident of each other which is simple, cheap, and effective, particularly in the raker-gage, owing to the mannerin which its gage-plate is adjusted and held, and also in the removal of all such parts as have heretofore prevented the saw-teeth points from being clearly viewed on a level with the overhanging parts which rest thereon, whereby a sectional straight-edge isformed with which to quickly locate such saw-teeth as might be too long or too short. The long teeth can be touched with the file until they are of the right length and the short teeth marked on their bevel by a stroke of the file and a coarser point filed thereon. In this way less filing is required, thereby saving time, files, and needless wear upon the saw and enabling the user thereof to always keep the saw-teethin proper shape.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a saw-gage, in combination, a frame having a series of posts presenting a horizontal line of bearings with spaces between the outer posts, a gage-plate embracing flanges on the inner posts and having its top face dressed in a true line with said bearings and provided with a long, round shaft extending through a drilled opening in the enlarged portion of the frame in which it fits snugly so as to produce a true up-and-down movement, an adjusting-screw inserted through a threaded opening in the lower part of the frame, and bearing against the end of the shank and capable of adjustment independently of any other part of the device, and a binding-screw extending through the frame at a right angle to the shank for holding the latter fast, substantially as described.

2. In a saw-gage, in combination, a frame,

a series of posts forming a horizontal line of bearings, a gage-plate and means for adjusting the same, and independent sets of plates presenting a hard and smooth surface throughout their entire length and forming a sectional straight-edge beneath which are left spaces through which the points of the cutting-teeth can be simultaneously viewed, substantially as described.

3. In a combined gage, straight-edge and jointer, in combination, a frame, a series of posts presenting a true line of bearings for the plates secured thereon, and forming a straight-edge in which spaces are left through which the cutting-teeth may be simultaneously viewed, a gage-plate'having a round shank extending through a correspondinglyshaped opening in the frame, an adjustingscrew having a collar working in a groove near the lower edge of the frame, a laterallyprojecting lug on the frame above the plane of said groove, a clamp or slide embracing said lug and having file rests or projections extending at right angles thereto at its upper and lower ends, and a cam for operating and holding said clamp or slide, substantially as described.

4:. In a saw-jointer, in combination, a frame provided with laterally-projecting

lugs

20 and 33, a file-clamp having two slots divided by a cross-bar, a set-screw 19 passing through one of the slots of the file-clamp into the lug 20 for holding the file-clamp in its place, and means for operating the file-clamp up and down, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
