SAW-TABLE GAG E.

SPECIFICATION forming part of Letters Patent No. 586,695, dated July 20, 1897.

Application filed March 30, 1897. Serial No. 629,896. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANK H. SAXTON, a citizen of the United States, residing at Bristol, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Saw-Table Gages, of which the following is a specification.

Myinvention relates to an improvement in saw-table gages; and the chief object of my improvement is simplicity of construction and convenience and efficiency in operation, especiallyin conveniently and accurately performing various work which has not heretofore been performed with saw-table gages.

In the accompanying drawings, Figure l is a perspective View of a saw-table with my improvement applied thereto. Fig. 2 is a plan view of the middle portion of my attachment on a somewhat larger scale than Fig. 1. Fig. 3 is a transverse section thereof on the line :0 a: on a still larger scale, and Figs. 4, 5, and 6 are reduced plan views with diiferent examples of work that may be done with my attachment.

In Fig. 1 A designates any ordinary sawtable having a saw 7 and an adjustable gage S of any ordinary construction. The table may also be provided with a supplementary bed 9, having dowel-pins 10, so that it may be readily detached from the table or attached thereto by the side of the saw 7, as shown.

My attachment or improved gage consists of a holdingboard 11 and a clamp or clamps 12, the same being portable and having no permanent connection with the table. This holding-board is provided with straight and parallel edges, and has secured to it one or more bracket-arms 12, which form the main portion of the clamp. These bracket-arms may be provided with any suitable form of shank, preferably of a branched form, as indicated by broken lines of Figs. 2 and 3, the

shank being designated as 13 in said Fig. 0.

The shank 13 is let into recesses in the bottom of the holding-board 11, so as to be flush with or a little inside of the surface of said board While its upright portion 14, Fig. 3, must not project beyond the back edge of the board. The front endof the bracket-arm is provided with some suitable or ordinary clam pin g device--for example, a clamp-screw 15, as shown. If desired, severalsmall points (not shown) may be arranged in the face of the board 11 for penetrating the work that is placed thereon, but said points are not essential. In some cases it is desirable to have a holding-point of considerable size, and, if desired, a plate 16 may be let into the face of the holding-board 11, immediately in front of the end of the clamp-screw 15 and provided with a pointed screw 17, which can be adjusted from the under side of the holdingboard to project to a greater or less extent. The clamp-screw acting on the top of the work will force this point into the under side of the work held on the board 11.

In the use of my improved attachment for saw-frames the work to be sawed is clamped upon the holding-board with the designed line for the saw to follow located immediately in front of the front edge 18 of said holdingboard. The holding-board may be of any desired length and provided with two or more of the clamps, as shown in Fig. 1, or with only one clamp, as shown in Figs. .4, 5, and (3.

In case it is desired to straighten one edge of a board the work is placed upon the holding-board 11 with a portion of its edge for the whole length projecting a little beyond the front edge 18 of the holding-board, as indicated by the board 19 in Fig. 4. It is securely fastened to the holding-board 11 in this position, when the holding-board, together with the work upon it, is placed with its back edge against the gage 8 of the saw-table and that portion of the board which projects beyond the face 18 is sawed oif parallel thereto.

This attachment may be used either with or without the supplementary bed 9, as it will ordinarily do no harm if the projecting edge to be sawed off does not rest upon the saw-table but said supplementary bed 9 may be used whenever it is desirable to have the portion of the board thus sawed off rest upon a table of the same height as the holding-board 11. After one edge of the board has been straightened by sawing off, as indicated by Fig. 4, the edge thus straightened may be used for the working edge against the ordinary gage in the ordinary manner.

In Fig. 5 I have represented the work 20 as held upon the holding-board for cutting the work obliquely, forming a triangular piece, as

ICO

will be readily observed by an inspection of said View. In Fig. 6 I have represented the work 21 as having previously been sawed or beveled off along the edge 22 and then set upon the holding-board for cutting off alongside of the face 18 at front edge of the holding-board, whereby the work is tapered at one edge from its middle in each direction. From these examples the adaptability of the attachment for doing various other work Will be readily suggested. If the gage 8 of the sawtable is of such a thickness that the board or Work placed on the holding-board mayproject over the rear edge thereof, the board maybe cut off at any desired angle.

I claim as my invention- 1. A portable holding-board 11 for a sawtable, said board having a free and unobstructed Work-holding face for Work of indefinite length, straight and parallel edges and clamping devices for holding the Work, said clamping devices being arranged to bear upon that side of the work which is opposite the Work-holding face of said board substantially as described and for the purpose specified.

2. A saw-tab1e gage which consists of a portable holding-board 11, having a free and unobstructed Work-holding face, straight and parallel edges, and the bracket or clamp arm 12 extending up from its longitudinal back edge inside of the gaging-face of said edge, and provided with a clamp-screw at its front end for holding the Work against the holding face on said board, substantially as described and for the purpose specified.
