CUTTING GAUGE Filed March 5, 1929 Patented Nov. 12V, 1929 j UNITED STATESl SAMUEL W. SIMS, OF PORTLAND, OREGON CUTTING GAUGE Application 'filed Maren 5,

- This invention relates to improvements in wood-working apparatus, and particularly to improvements in adjustable gauges for dadosawing machines and analogous apparatus.

The obj ect of my invention is the provision of a gauge of simple construction that may be readily applied in rconnection with a dado-L saw or the like and which is especially adapted for use in the grooving of dadoes in the head and sill members of window frames or for other similar purposes where a plurality of pieces are to be grooved with similar spacings therebetween. y

A further object of the invention is to pro-y vide apparatus of the above described type including a plurality of flexible gauge-strips mounted upon slidable blocks within a holding-frame and wherein the strips are indi vidually adjustable to vary the relative distances apart of the cuts to be made with littlev trouble or delay enabling the utilizationof a gauge where but a comparatively small number of operations are to be performed. j

Other objects and advantages of the invention and objects relatingr to details of the invent-ion will be readily apparent in the course of the detailed description to follow.

The accompanying drawings illustrate by way of example one orm of the invention, in

which:

Figure 1 is a perspective view of an embodiment of my invention mounted in operative condition upon a grooving machine.

Fig. 2 is a partial plan view of the inven tion, detache Fig. 3 is a view in side elevation of the same. y

Fig. 4 is a view in longitudinal section upon line 1r-4 of Fig. 2, upon an enlarged scale.

Fig. 5 is a view in cross section on line 5-5 of Fig. 2 upon an enlarged scale.

Fig. 6 is a view in end elevation of the in-k vention mounted in operative position as in Fig. 1. j

Referring to said views, the reference numeral 1 indicates generall a gauge-device of myy invention and 2 the ody of a machine upon which the same is adapted for use.` 3 indicates a fixed table upon said machine and 5 a table horizontally movable on said ma- 1929. Serial No. 344,525.

chine in thel same plane as the table 3 and operable in a well-known manner. Adadosaw 6 is` mounted on said machine and is adjustable therein to make various depths of cuts. A board 7'is shown upon said tables and is movable with the table 5 to and from said saw. n f

Numerial 8 designates the frame of my improved gauge device and is detachably secured upon the sliding table 5 abutting upon the ledge 9. Saidframe is formed with a recess 10 extending from one end 11 which may overhang the table 5 to the proximity of the saw. Said recess may be formed with rectangular walls and of the same dimensions throughout. i

Adjustably mounted in the recess of said frame is a slidemember 12 of approximately the length of the recess and arranged to be secured therein inset position by means of set-bolts 13. A recess 15 is formed longitudinally of said slide having undercut or dovetailed side edges 16 in which gauge-'blocks 17 18 and 19 are adjustably mounted. Said ygauge-blocks are provided with inclined side walls corresponding to the side edges 16 of the recess 15 and may be secured in set posif tions by means of set-screws 20 bearing upon the bottom of the recess. v

Upon each of said blocks ay gaugestrip 21 is secured of relatively thin spring steel or other suitable material. Said strips are fastened to the respective blocks adjacent one end by means of `screws 22 and have'their opposite ends 23 resiliently deflected outwardly to protrude beyondthe face of the frame 8. One or more of said blocks may be provided with an additional gauge-strip, as 25, which is adjustably secured thereto by set-screws 26 received in slots 27 of the strip. y

- Brackets 28 are secured upon the face of said frame having sloping ledges 29 thereon upon which the board 7 is rested at an angle to the table 5 when cuts inclined to the planes of theilat sides of the boards arey vto be made, as seen in Figs. l and 6. Said' brackets are adjustable to various heights to vary the angle of the board, as indicated. The parts and devices of theslide and asr blocks are all disposed within the recess and below the level of the frame face except the ends 23 or" the strips 21 and 25 and these are deflected inwardly thereof when a board is laid against their outer sides and against the end of the one being utilized as a gauge-stop.

The mode of operation of the device is readily understood. The ends 23 of the gauge- strips 21 and 25, serve as stops for the boards in determining the location of the dado-grooves to be made therein, the end of the board engaging thereagainst and so held by the operator while a saw-out is being made. The blocks 17, 1 8 and 19 are disposed 'and secured in the slide-recess 15 in positions so that suchende of the respective strips will each locate precisely a groove to be made. This is done readily accordingly to the dimensions oi' the window-frame and the required location or" the grooves for setting in the vertical frame members of the window-traine. rlhe board 7 illustrated represents a sill-member oi a window-traine and the blocks will be so set and secured in the slide that the strip-ends 23 will correctly position the cuts to be made when the end 30 is held thereagainst.

With the device mounted as described uponv the machine and as seen in Fig. 1, the end of the board is first placed against the strip 21 of the block 19 and the 0roove 81 is formed by sliding the table 5, trame and board upon the saw. The board-end is then engaged with thestrip 21 oi the bloclr 18 and the groove 32 is made in a similar inanner while the board overlies the strip of the block lland depresses it within the frame recess 10. The board is then moved to engage the neXt strip, 25,7o the blocl; 18 to malre the cut 33, and sov on.

1 The provision oi' theV two strips 2l and 25 upon'the same bloelr is intended to maire convenient the location of the two grooves inV relatively close order or in making a wider cut than that to be made at one stroke of the saw. y

The provision oiQ the slidingrineniber 12 within the traine to car 1y the blocks upon which the strips are car ied is designed to accommodate boards or" diiierentlengths hut having the grooves cut therein with thesanie spacings therebetween. Ordinarily headmembers and sill-members of windowtrames'are of diderent lengths' Vbut have their grooves for the acconnnodation of the vertical members with similar spacings. Thus the; slide may be adjusted lengthwise ot the frame and secured to compensate for the entra length of the sill-member and then moved back to take the end of the headmember without disturbing the relative spacing of thestrips.

It will be understood that theV device may be'employedI in awide variety or uses other than that to which'it has been applied in the present illustrated example, such as in cut-oli saws in cutting stock` to various lengths and that with the foregoing description talzen in connection with the accompanying drawings the advantages of the construction and operation Aof my improved gauge-device will be readily apparent. It will be understood that the structure shown is merely illustrative and that such changes may be made therein in adapting it to its various uses as are within the scope of the following claims.

Having described my invention, what I claim, is

1. A. gauge-device of the class described, a frame having a longitudinal recess therein, a member slidable in said recess, and iged kto be adfjustably secured therein, slit e-niember having an undercut recess its length, a plurality of blocks sec-ur- .s and' a resiliently flexible gaugeat one end to each said block -"e-c.cvice of the class described,
