FENCE FOR JOINTEIRS Filed April 18. 1930 2 Sheets-Sheet 2 WI TWESSES Patented Jan. 27, 1931 UNITED STATES PATENT orrlcs HERBERT E. TAUTZ, OF MILWAUKEE, WISCONSIN, ASSIGNOR '10 DELTA MANUFAC- TUBING COMPANY, OF MILWAUKEE, WISCONSIN, CORPORATION 01" WISCONSIN FENCE FOR Application filed April 18,

The invention relates to fences for jointers and other wood-working machines.

An object of the invention is to provide a work-guiding fence which is adjustably mounted at the front end of the work-receiving table of a jointer, or other woodworking machine, and below the top surface of the table to thereby leave the table surface free from grooves or ways in which chips or sawdust may collect, or in which the work may accidentally engage to interfere with proper operation.

Another object of the invention is to provide fence-adjusting means which are located at the front end of the table where they are easily accessible to the operator and do not interfere with the work.

A further object of the invention is to provide a fence which has a pivotal axis extending substantially in the plane of the table, and which includes a depending portion at one end pivotally mounted on a bracket ad'ustably secured to the front end portion 0 the table, such pivotal mounting comprising a segmental ri on one member fitting in a segmental groove in the other co-operating member, and the fence havin a heel or lug which pivotally bears on the ta le surface adjacent the cutter-head of the machine.

A further object is to provide a fence mounting includlng a die-cast bracket having a stop for quickly determining the position of the fence at right-angles to the table, and also having an angular scale for facilitating the angular adjustment of the fence.

A further object is to provide a fence which, with its supporting bracket, can be quickl and easily removed from the table, and whic can be readily replaced on the table and be rapidly and accurately adjusted both with respect to the cutter-head and with respect to the surface of the table.

A further object is to provide a rigid lightweight fence having an integral longitudinally-extending tubular portion of substantially triangular cross-section;

A further object is to perfect details of construction of the fence mounting and to reduce the cost of manufacture in order to render the device suitable for small size ma- JOINTERS 1880. Serial No. 445,888.

chines in the so-called home work shops. The invention further consists in the several features hereinafter set forth and more particularly defined by the annexed claims.

This application constitutes a continuation in part of my co-pending application for Planer attachment for jointers, Serial No. 355,231, filed April 15, 1929.

Fig. 8 is a fragmentary detail View showing a modified form of fencemounting.

In these drawings, the numeral 10 designates a jointer base frame having a cutterhead 11 mounted in suitable bearings therein and driven in any suitable manner. A front table 12 and a. rear table 13 are slidably mounted on inclined ways 14 formed on the base frame 10, so as to be independently raised or lowered with res eat to the knives of the cutter-head, as usua The adjusting means for the table includes a pair of adj usting nuts 15, each of which is threaded on a respective screw 16 secured to the base frame.

The front table 12 is provided at its front end with a guide channel 17 which extends transversely along the under side of the table in parallel relation to the axis of the cutterhead. The opposite side portions of the channel 17 are formed with rooves 17 of rectan lar cross-section whic slidably receive t erein the opposite flanges 18 of a diecast metal bracket 19, portions of which depend from the channel 17 and extend forwardly of the front end of the table 12. A clamping screw 20, having a slidably mounted handle 21 in its head portion, is threaded angularly into the bracket 19 to engage an abutment 22 formed along the upper wall of V the channel 17, to thereby urge the bracket downwardly and forwardly into firm engagement with the grooves 1 By this adjustment the forward flange 18 of the die-cast bracket is brou ht to bear against the lower and side face 0? the forward roove 17, and the vertical forward face 23 o the bracket 19 is brou ht into a plane at right-angles to the upper ace of the jointer table 12.

An arcuate segmental rib 24 projects integrally from the forward face of the die-cast bracket 19, and is concentric with a horizontal axis which is normal to the forward face of the bracket 19 and which lies substantially in the plane of the upper surface of the jointer table, or in some instances slightly above the table surface. A plate 25 bears against the vertical surface 23 of the bracket 19 and is provided with an arcuate segmental groove 26 within which slidably fits the segmental rib 24 on the bracket, to thereby define for the plate an axis of rotation lying substantially in the plane of the upper surface of the jointer table.

A shouldered clamping screw 27 having'a slidably mounted handle 28 in its head portion, is threaded into the bracket 19 and extends through an arcuate slot 29 formed in the plate 25. The shouldered head portion of the screw 27 engages a washer 29 which receives the screw therethrough and which bears against the plate 25 to clam the plate in angularly adjusted position. X lug 30 is formed integrally on the die-cast bracket 19 and has a stop-screw 31 threaded therein for engagement with a lug 32 formed on the plate 25, to thereby limit the angular displacement of the plate in one direction. A look not 31' holds the screw 31 in ad'usted position. An angular scale 33 is molded on the die-cast bracket 19 and co-operates with an index pointer 34 secured to the plate 25, to thereby facil tate the angular adjustment of the plate. The index pointer 34 is of angular shape and has one end portion rotatably fitting within a l bore formed in the edge portion of the plate 25. The pointer can thereby be swung into pro or registration with the scale 33, and is hel in position b a set screw 34.

A fence 35 is xedly secured to the upper portions of the plate 25 by means of screws 36, and presents a flat work-enga ing face 37 whlch is disposed at right-ang es to the uppersurface of the table 12 when the lug 32 on the fence plate engages the stop-screw 31. The fence 35 is provided with integral re-enforcin walls 38 which form therewith a rigid tu ular structure ta ring toward the ree end of the fence an presenting a substantially triangular crossesection. At t point adjacent the cutter-head 11, a rounded heel or lug 39 is formed on the lower edge of the fence to pivotally engage the upper surface of the jointer table 12 and thereby prevent springing of the fence by a downward pressure, especially in the inclined positions of the fence. A recess 40is formed in the lower edge of the fence to provide clearance for the cutter-head.

In the modified form of fence mounting shown in Fig. 8, the jointer table 112 is provided in its front end portion with a transversely-extending channel 117 opening laterally to receive a flanged die-cast bracket 119 which is urged forwardly and downwardly against the recessed walls of the channel by means of a clamping screw 120. The plate 25 carrying the fence 35 is fitted on the bracket 119 in a manner heretofore described, and is clamped thereto by a screw 27. This form of fence mounting is generally similar to that first described except for the disposition of the channel 117 which opens laterally instead of downwardly.

The assembl comprising the fence 35, fence plate 25, and liracket 19, is of 'unitary charactor, and is capable of being shifted transversely of the table, or removed from the table, after loosening the clampin screw 20. During such shift or removal, t e flanged portions 18 of the bracket 19 slide along the grooves or ways 17 of the channel 17, which is open at its opposite ends. When the fence assembly is to be replaced on the table, the bracket 19 is slid into the open-ended channel 17 a selected distance and the screw 20 is then tightened to clamp the assembly firmly in place. When the screw 27 is tightened, the fence plate 25 is clamped firmly against the forward vertical face of the bracket 19, whereupon the fence 35 extends longitudinally of the table 12 and at right-angles to the axis of the cutter-head. The abutment of the lug 32 with the sto screw 31 serves to place the plane of the ence at right-angles to the upper surface of the table 12. In this manner, the more commonly used 90 adjustment can be readily obtained. When the angular position of the fence is to be ad- 'usted, the screw 27 is loosened and the fence plate 25 rotated to a selected position as indicated by the position of the pointer 34 with respect to the scale 33, whereupon the tightenin of the clamping screw 27 will secure the once firmly in its adjusted position.

The clamping screw 27 not only clamps the fence assembly a ainst movement, but also insures a disposition of the fence at rightangles to the axis of the cutter-head, so that rabbeting, tenoning, and molding operations can be accurately performed.
