1 Claim.
The present invention relates to work guides for wood working machines, and is particularly concerned with an improved work guide to be used on shapers or similar tools.
The present application is a division of my prior, application Serial No. 19,335, filed May 2, 1935, for Wood working tools, which has resulted in the issuance of Patent No. 2,076,511 dated April 6, 1937.
One of the objects of the invention is the provision of an improved work guide for shapers which is adapted to serve also as a guard to protect the hands of the user from the cutter, and which is alsoadapted to provide for the discharge :-1. of the shavings or cuttings through the work guide,
Another object of the invention is the provision of an improved work guide for shapers having provisions for adjusting the depth of cut into 20 the work piece.
Another object of the invention is the provision of an improved work guide having a rear portion adapted to be adjusted and. secured and having a forward portion or section which is 5 adapted to be adjusted with respect to the rear portion after the former has been secured in place.
Another object of the invention is the provision of an improved shaper fence or work guide 30 which is capable of inexpensive manufacture and which is so constructed as to avoid clogging by chips.
Other objects and advantages of the invention will be apparent from the following description,
35 in which similar characters indicate similar parts throughout the several views.
Referring to the drawings, of which there are two sheets:
Fig. 1 is a top plan view of a shaper provided 40 with a work guide constructed in accordance with the present invention;
Fig. 2 is an elevational view taken from the top of Fig. 1;
Fig. 3 is a vertical sectional view taken on the 45 plane of the line 3-3 of Fig. 1 looking in the direction of the arrows showing the details of construction of the adjustable front section of the guide;
and
Fig. 4 is a vertical sectional view taken on the 50 plane of the line 4-4 of Fig. 1 looking in the direction of the arrows showing the chip discharge opening in the guide.
Referring to Fig. 1, I indicates in its entirety the shaper which is provided with a table II s5 supported upon a base l2. The base has a suitable arrangement for journaling the cutter shaft I2 and a suitable arrangement for raising and lowering the cutter shaft with respect to the top of table II. The shaft l2 and cutter I3 arearranged concentrically with respect to an aperture I4 in the table top II.
The shaper is preferably provided with a combined fence and. guard I5 which may consist of a cast metal member having a pair of attaching flanges I6, I! joined by an upwardly projecting guard portion I8. The guard portion I8 comprises a relatively short and wide oval conduit i9 leading from the vicinity of the cutter I3 to the leftedge of the table in Fig. 4. The conduit I9 is adapted to discharge the chips which are re-- moved from the work piece by the cutter I3.
In order to provide for the adjustment of the work guide I5 into close relation with the cutter I3, the guard portion I8 is provided with a semicircular groove 20 which is of sufficient size to receive the cutter I3 without contact when the cutter is elevated to the top of the guard portion I8 and the guide I5 is adjusted into close proximity with the cutter. The guard portion I8 may extend over at 2I behind the cutter while it is narrower at the point 22 to. permit room for adjustment of an adjustable guide shoe 23.
Both the attaching flanges I6 and I1 are provided with lower flat engaging surfaces 24, 25 located at the elongated slots 26, 21. The flange I6 extends over behind the cutter I3 that is at the left of the cutter in Fig. 1 and has an upwardly extending flange 28 which is at right angles to the plane of the table top II and to the plane of the surfaces 24, 25. Vertical flange 28 preferably supports a wooden shoe 29 comprising a strip of hard wood which is secured to the flange 28 by one or more screw bolts and nuts 30, all preferably having their heads countersunk in the shoe 29. The flange I1 is of lesser area than the flange I6 terminating at the line 22, previously mentioned, in order to permit room for adjustment of. the shoe 23.
The shoe 23 is similar in construction to shoe 29, but it is supported upon a vertical flange 3! by means of one or more screw bolts 32. Vertical flange 3| is a part of a cast metal fitting 33 which has a. diagonally extending socket 34. The socket 34 is adapted to receive the reduced cylindrical end 35 of an adjustment plunger 36. End 35 is secured in place by set screw 3'! and by the engagement of the annular shoulder 38 with the fitting 33. The larger cylindrical portion 39 of the plunger 36 is provided with an axially extending slot 40 on its upper side, and this larger threaded member 43 slidably engages in slot 4Q to prevent rotation of the plunger 36.
Plunger 36 is also provided with an axially extending threaded bore 45 receiving the threaded end 46 of a shaft 41 which is journaled in a counterbore 48 located in the right end of body Shaft 47 has an integral thrust flange 49 42. located in the bore 4|. The outer end of shaft 41 is received in a bore 50 of the crank where it is secured by a cross pin 52 that may be riveted in place. The crank 5| thus serves as a thrust bearing engaging the end of the body 42. When the crank 5| is rotated the threaded end 46 in the bore 45 causes the plunger 36 to progress forward or backward. This causes the shoe 23 to be adjusted downward or upward in Fig. 1.
The shoe 23 is adapted to engage the flat surface of the work piece 20 as the work piece approaches the cutter IS. The shoe 29 may be so adjusted that it provides engagement for that part of the work piece 20 which has been shaped.
The position of the combined guard and work fence I5 is determined by its adjustment on the table top H where it may be clamped by the threaded members 53, 54 which thread into the portion 55, 56 in the table II. Both guides may be simultaneously adjusted and clamped in position by means of the screw bolts 53, 54, thereby T making the adjustment of the device faster and saving time in the use of the machine It will thus be observed that I have invented an improved work guide and guard for wood working tools such as shapers, by means of which the depth of cut may be predetermined and the work may be satisfactorily guided during the shaping operation.
While I have illustrated and described a preferred embodiment of my invention, many modifications may be made without departing from the spirit of the invention, and I do not wish to be limited to the precise details set forth, but desire to avail myself of all changes within the scope of the appended claim.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
In a wood working machine, the combination of a supporting table with a combined cutter guard and fence, said fence having an attaching flange and a guide flange, and having a chip conduit formed adjacent a cutter carried by said table, said attaching flange having adjustable means for securing it to the table, and a plunger housing carried by said attaching flange, said plunger housing having a bore and a counterbore,
with an annular shoulder betweensaid bore and counterbore, a plunger slidably mounted in said bore, a screw shaft having thrust bearings on each end of said counterbore, and rotatably 'mounted in said counterbore, said screw shaft 'having threaded engagement with said plunger,
and an adjustable guide shoe carried by said plunger and extending in parallel relation with respect to said other guide flange.
