' 1 claim.4 (ci. 14a- 174) The invention relates to wood-working machines and more particularly to circular-saw machines. .in a home work-shop and elsewhere, the user of a circular-saw machine or other word-Working machine having a work-supporting vtable generally desires a table of large size to insure accurate work and to handle large pieces, and in some cases prefers a table of a predetermined size to suit special work or to t in available space. Large metal tables are somewhat expensive, but large wooden tables are found to be quite satisfactory and can be constructed at a relatively low cost by the user or by a local mill.
It is an object of the present invention to provide means whereby an inexpensive wood-working machine having a wooden table of any desired size can be easily and quickly assembled by a user, the construction being of such character as to permit accurate guiding of work on the table.
Another object Aof the invention is to provide metal fittings whereby a durable and accurate wood bar fence or work guide of any desired length can be inexpensively constructed by the user.
A further object is to provide a fence which can be clamped at both ends to prevent springing, the clamping means 4for both ends being operable from the frontend of the fence.
The invention further consists in the several features hereinafter described and claimed.
One specific embodiment of the invention is shown in the accompanying drawings, wherein Fig. 1 is a top plan view of a circular-saw ma- Y chine constructed in accordance with the invention;
Fig. 2 is a longitudinal sectional elevation of the 'machina taken generally onthe line 2-2 of Fig. l, two different positions of a swingable saw support being shown in full and dotted lines;
Fig. 3 is a transverse sectional elevation of the machine, taken generally on the line 3.-3 of Fig. 1, two different positions of a tiltable saw frame being shown in full and dotted lines; l
Fig. 4 is a sectional view taken on the line 4--4 of Fig. 1;
Fig. 5 is a side elevation of the table and ripping fence, parts` being broken away and parts being shown in section; and
Fig. 6 is a front view of the table and fence, parts being broken away and parts being shown in section.
In these drawings, I5 designates a-flat horlzontal mounting plate having parallel opposite sides and preferably having rounded opposite ends; The mounting plate is of metal and is intended to be secured to a-rectangular wooden saw table or bench I6 of any suitable size, the plate covering an opening`|1- in the table and being ush with the upper surface of the table to form a work-supporting surface. The end portions of the plate are set into rabbets I8 in the table and are fastened to the table by screws I9 passing through bores 20 in the plate.
The mounting plate I5 forms part of a power tool unit, here indicated to be a circular-saw unit. An elongated opening 2l is formed in the mounting plate and receives therein in flush relation I an insert plate or panel 22 having a slot 23 extending parallel to the side edges of the mounting plate to admit the upper portion of a circularsaw 24. The insert is preferably formed by a soft metal die-casting.
The saw 24 is carried on an arbor 25 rotatably mounted in a swlngable member 26 and having a drive pulley 21 at its outer end, the saw table being suitably recessed to clear the pulley, as indicated in Fig.,3. The swlngable member 26 has a hub portion 28 pivotally carried on a rod or shaft 29 extending parallel to the saw arbor and secured to a tiltable metal frame or housing 30 forming a sawdust chute, the bottom of the housing sloping to a discharge opening 48. A
collar 54 confines the swlngable memberv 26` on the rod 29.
The opposite end wallsof the housing 30 have respective arcuate ribs 33 formed thereon and movably tting in arcuate grooves 34 formed in' ports.for the insert panel 22, the panel being dey tachably secured to the plates 38 i'n any suitable manner. I
The tiltable frame or housing 30 has parallel side walls 46 and 41 between which the saw is located. At its upper portion the frame or housl ing 30 is cut away at one side, as seen in Fig. 3,`
to permit tilting of the frame. The upper portions of the end walls of the frame are extended yto form end anges which are connected at V-belt 59.
frame, thus insuring rigidity. The side wall 46 is suitably apertured to admit the sawarbor 25.
A ribbed plate 55 is adjustably carried by the lower end of the swingable member 26 and has secured thereto by screws 56 an electric motor 51. 'Ihe motor shaft has a pulley 58 which is drivingly connected to the saw arbor pulley by a The tension on the belt is adjusted by shifting the plate 55 which, in the present instance, is provided with parallel studs 60 slidably tting in apertured lugs 6| formed on the lower end of the frame 26, the studs being secured in adjusted position in the lugs by set screws 62.
A horizontal shaft 63 is journalled in lugs 64 formed on the side wall 46 of the ,tiltable frame 30 and projects beyond each end of the frame, the shaft being retained against axial movement by collars 65 engaging the lugs. One end of the shaft is provided with a hand` Wheel 66. The other end of the shaft, which is screw-threaded, carries a nut or traveller 61 which is connected by a link 68 with a lug 69 formed on the lower end of the swingable member 26. By turning the hand-wheel 66, the nut 61 is caused to move along the shaft, thereby shifting the swingable member 26 to adjust the projection of the circular saw above the table. The two extreme positions of the swingable assembly are shown by full and dotted lines, respectively, in Fig. 2.
Means are also provided for adjusting the angle of the saw with respect to the saw table. In the present instance, a forked bracket 12 is secured by screws 13 to the lower portion of the side wall 41 of the tiltable frame or housing 30. An internally screw-threaded sleeve.14 is transversely trunnioned in the bracket 12 by screws 15, and is engaged by a threaded shaft 16 lwhich is inclined and may extend toward either side of the table. Near its outer end, the shaft is journalled in a bearing 11 having a swingable mounting on a bracket 18 secured by screws 19 to any suitable part of the saw table or bench, such as the under side of the saw table. A hand- Wheel on the outer end of the shaft 16 serves to turn the shaft and thus adjust the angle of the saw, the bearing 11 being placed between the hand-wheel 80 and a collar 80' on the shaft. The shaft 16 is preferably provided with stop nuts 8| to engage the sleeve 14 and thereby predetermine angular positions lozl' the saw, such as the vertical position and a position 45 vfrom the vertical.
In order to provide durable and accurate guideways for a slidable gage, Va pair of parallel upwardly opening metal channel bars 82 are let into the wooden saw table |6 near and parallel Ato the opposite side edges of the mounting plate' I5 and are secured to the saw table by screws 83.
Metal guide bars 64 extend along the parallel front and rear edges of the table I6 and are secured thereto by screws 85 passing through spacing washers 86. The upper edges of the .guide bars 84 are spaced below the plane of the table top to avoid blocking the ends of the channel bars 82,'and each guide bar is here indicated to project beyond one of the side edges ot the table.
A rip gage or fence is mounted on vthe guide bars 84 and comprises a wooden fence bar 81 secured at its front end to a metal head or bracket 88 slidably embracing the front guide bar 84, the bracket having inturned lips 89 engaging the rear face of this guide bar and releasably clamped thereto' by a clampingscrew 80.
A metal insert bar 9| is mortised into the lower edge of the wooden fence bar 81 and is secured thereto by screws 92. The insert bar is secured to the bracket 88 by screws 93 and 94, the latter passing through a somewhat larger opening in the bracket so as to permit angulai` adjustment of the fence bar 81 to a position parallel to the plane of the saw.
A metal block 96 is secured by a screw 91 to the lower edge of the rear end portion of the fence bar to rest on the rear guide bar 84. A metal clamping member 98 is guided in a vertical slot 99 formed in the rear end of the fence bar and has a forwardly bent lower end |00 engageable with the lower edge of the rear guide bar. The upper portion of the clamping member is inclined and has a cam engagement with an inclined face |0| formed on the fence bar. A downturned end lug |02 is formed on the upper portion of the clamping member and is disposed in a notch |03 formed in the. fence bar. A rod |04 rests in a groove |05 formed along the upper edge of the fence bar and has a headed end passing through the lug |02. The front end portion of the rod is screw threaded and passes through.
a washer |06 secured by screws |01 to the front end of the fence bar. A thumb-nut |08 on the front end of the rod is engageable with the washer |06 for operating the clamping member 98.
When the fence is to be clamped in position, the user rst clamps the bracket 88 to the front guide bar 84 by means of the clamping screw 90, and then tightens the thumb-nut |08 to draw the rod |04 forwardly, causing the rear clamping member 98 to ride up on the inclinedface |0| of the fence bar and thereby clamp the rear guide bar between the block 96 and the lower end of the clamping member 98. With this construction it is not necessary for the user to reach over the table or pass around to the rear end of the table in order to clamp the rear end of the fence.
In assembling the machine it is only necessary for the user to obtain the power tool unit and the various metal fittings andA to provide a rectangular wooden saw table of any desired size having recesses to receive the mounting plate 5 and channel bars 82, the several parts being readily secured in place. The power tool unit and other metal parts are capable of accurate' and economical factory production, while the table is of such character that it can be inexpensively constructed by the user or by a local mill. The mounting plate is detachable from the housing 30 and may be used as a guide for cutting the opening |1 and rabbets |8 in the saw table. The mounting plate is then secured to the saw table and the housing-supporting brackets 35 are subsequently attached to the plate. The channel bars 82 are cut off, if necessary, to suit the length of the table. The shaft 16 may extend toward either side of the table to suit the convenience of the user. 'Ihe guide bars 84 are secured to the opposite end edges of the saw table, and the wooden fence bar 81 is secured to its metal fittings to fonn the complete fence.
Since the saw arbor and motor are both carried by the same shiftable member, the belt tension and relative position of the pulleys are not disturbed when the saw adjustments are eiected, and the user has unobstructed access to all sides of the table.
The rounded shape of the mounting plate ends and the table rabbets prevents catching of the 75 front edge of the work. as the work is fed to the saw.
'I'he rounded ends of the mounting plate are prefer lbly dened by arcs of a circle, the center of whi h is at the center of the plate, so as to permit a slight angular adjustment of the plate about this center without binding against the table or changing the fit of the plate ends with respect to the table rabbets.
