7 Claims. The invention relates to jointers and more particularly to jointer fences;
An object of the invention is to provide an improved jointer fence which is mounted in such 5 manner that the lower edge of the fence will be close to the rear table of the jointer irrespective of the relative raising or lowering of the front table of the jointer, thereby insuring proper support for the work as it passes over the rear table. 10 Another object of the invention is to provide a jointer in which the fence is mountedon the rear jointer table and has controls which are accessible at the front or feeding end of the jointer. A further object of the invention is to provide 15 a jointer in which the fence can be adjusted from either end of the machine.
The invention further consists in the several features hereinafter described and claimed.
In the accompanying drawings, illustrating one 20 specific embodiment of the invention, Fig. 1 is a side elevation of a jointer constructed in accordance with the invention;
Fig. 2 is a top plan view of the jointer; Fig. 3 is a rear elevation of the jointer showing 5 the fence in one of its angular positions, two other angular positions being indicated in dotted lines, parts being broken away and parts being shown in section;
Fig. 4 is a detail elevation of the fence mount- 30 ing, parts being broken away and parts being shown in section, and
Fig. 5 is a detail sectional view taken on the line 5-5 of Fig. l.
In these drawings, l designates a jointer base 35 having hearings in which is journalled a cutterhead ll driven in any suitable manner. A front table l2 and a rear table l3 are slidably mounted on the usual inclined ways I4 formed on the base l0, so as to be capable of raising and lowering 40 with respect to the cutter-head. The tables are independently movable by means of any suitable adjusting means, here shown to include adjusting knobs IS. The front table I2 is formed at one side with a rabbeting arm or ledge l6, and the rear table I3 is formed at the same side with a grooved edge I! to provide clearance for rabbeted work.
The rear table I3 is formed with transversely extending ways l8 extending parallel to the axis 50 of the cutter-head. In the present instance, the
ways l8 are formed by an open-ended guide channel which extends along the under side of the table adjacent the rear end of the table.
A bracket I9 has a portion 20 fitting in the 6 ways l8 and a vertical plate portion 2| projecting to the rear of the rear table, the plane of the plate portion being parallel to the axis of the cutter-head and at right-angles to the table top. A crescent-shaped sector plate 22 slidably bears against the vertical rear face of the bracket 5 and is pivotally connected to the bracket in anysuitable manner. By way of illustration, the sector plate is provided with an arcuate segmentalgroove 23 within which slidably fits an arcuate segmental rib 24 formed on the bracket, to thereby define for the sector plate an axis of angular displacement lying substantially in the plane of the rear table top.
A fence 25 is rigidly secured at its rear end to the upper portion of the sector plate by means of screws 26, and presents a fiat face 21 against which the work is slidably pressed. The lower edge of the fence is beveled, as seen in Fig.- 4, A and is close to, or in contact with, the rear table top. Preferably, only a heel or lug 28 on the fence is in contact with the rear table top, the heel being adjacent the cutter-head. A recess 29 is preferably formed in the lower edge of the fence to provide clearance for the cuter-head. The fence is here shown to have longitudinallyextending reinforcing ribs 30. The fence extends over the front and rear tables and is here indicated to project forwardly of the front table.
If desired, the fence 25 may be formed integral with the sector plate 22. 30
The rear jointer table has a downwardly projecting part 3| provided with a horizontal bore 32 extending longitudinally of the table. A tubular shaft 33 is journalled in the bore 32 and projects through the base I0. A cam 34 is carried 35 on the rear end of the tubular shaft and is engageable with a horizontal track 35 formed on the bracket I9 for urging the bracket upwardly against its ways l8 and thereby locking the bracket against movement. At its front end the tubular shaft carries an operating handle 36 and at its rear end the shaft carries a. similar operating handle 36, the handle 36 being adjacent the front end of the jointer.
Within the tubular shaft is journalled a pinion shaft 31 which projects therefrom at each end. Adjacent its rear end, the shaft 31 carries a pinion 38 which meshes with a horizontal rack 39 formed on the bracket [9 to effect movement of the bracket along its ways. At its front end the shaft carries an operating knob 40 and at its rear end a similar knob 40.
The bracket l9 projects above the plane of the rear table top and carries a tubular portion 4t which extends over the rear table parallel to the fence. A tubular shaft 42 is-journalled in the bracket portion 4i and projects forwardly beyond the front table. A cam 43 is carried on the rear end of the tubular shaft 42 and is engageable with an arcuate track 44 presented at the outer side of an arcuate slot 45 which is formed in the sector plate 22, the slot being concentric with the axis of the fence. Rotation of the tubular shaft 42 urges the cam 43 against the track 44 and thus locks or clamps the sector plate and fence against tilting. At its front end the tubular shaft 42 carries an operating handle 46, and at its rear end a similar operating handle 46.
Within the tubular shaft 42 is journalled a pinion shaft 41 which projects therefrom at each end, the rear portion of the shaft 41 passing through the arcuate slot 45. The shaft 41 carries a pinion 48 which meshes with a segmental rack 49 formed at the outer side of the arcuate slot 45 to effect swinging of the fence to various angles with respect to the table. At its front end the shaft 41 carries an operating knob 50 and at its rear end a similar knob 50'.
Preferably, the fence is movable to a vertical position and to inwardly and outwardly tilted positions 45 wardly tilted position being determined by the engagement of the fence with a suitable stop abutment on the bracket I9. If desired, the adjustment of the fence to much-used angular positions may be facilitated by stop means such as those shown in my United States Letters Patent No. 1,967,791, issued July 24, 1934, and No. 1,975,562, issued October 2, 1934.
In operation, the fence is adjusted to a desired angular position by rotating the knob 50, and the fence is then looked insuch position by tuming the handle 46. The fence is adjusted laterally by rotating the knob 40, and the fence is locked in such adjustment by turning the handle 36. All the above adjustments are effected by an operator standing at the front or feeding end of the machine, although, if desired, the same adjustments can be made from the rear end of the machine by manipulating the rear controls. The front table I2 is adjusted to produce the desired depth of cut. The work is fed alongthe tables and in its travel is pressed against the fence. Since the lower edge of the fence remains close to the rear table top regardless of the depth of cut for which the front table is set, the work will be adequately supported by the fence when the work travels over the rear table.
from the vertical, the extreme out- By mounting the fence at the rear end of the rear table, it is possible to eliminate ways or grooves in the table top, so as to avoid obstruction to the smooth travel of the work.
What I claim as new and desire to secure by Letters Patent is:
1. The combination of a jointer having relatively raisable front and rear tables, there being transversely extending ways at the rear end of said rear table, a bracket movable on said ways, and a fence extending over said tables and having a pivotal mounting on said bracket, the lower edge of said fence being close to the rear table.
2. The combination of a Jointer having relatively raisable front and rear tables, and a fence extending over said tables and having a mounting at the rear end of said rear table, the lower edge of said fence being close to the rear table.
3. The combination of a jointer having relatively raisable front and rear tables, and a fence extending over said tables and having a mounting at the rear end of said rear table, said fence being swingable about an axis substantially coincident with the top surface of said rear table and having its lower edge close to said surface.
4. The combination of a Jointer having relatively raisable front and rear tables, a fence extending over said tables and having a mounting on said rear table, the lower edge of said fence being close to the rear table, and controlling means for said fence extending to the front of the jointer.
5. The combination of a Jointer having relatively raisable front and rear tables, a fence extending over said tables and having a mounting on said rear table, the lower edge of said fence being close to the rear table, and clamping means for said fence extending to the front of the jointer.
6. The combination of a jointer having relatively raisable front and rear tables, a fence extending over said tables and having a mounting on said rear table, the lower edge of said fence being close to the rear table, and controlling means for said fence extending to the front and rear portions of the jointer.
7. The combination of a jointer having relatively raisable front and rear tables, there being transversely extending ways at the rear end of said rear table, a bracket movable on said ways,
a fence extending over said tables and secured to said bracket, the lower edge of said fence being close to the rear table, and clamping means for said bracket extending to the front of the jointer.
