WOODWORKlNG-IVIACHINE.

Speccaton of Letters Patent.

Patented June 25, 1907;

Application filed April 9,1906. Serial No. 310,704.

vVfashington, have invented certain new and useful Improvements in Voodworking-Machines, of which the 'following is a speciiication, reference being had therein to the accompanying drawing.

This invention relates to woodworking Inachines and especially to planers, and consists of novel devices and arrangements whereby I am able to plane by Inachinery long timbers of varying bevel, of varying thickness, and with a straight edge or a concave edge or a convex edge.

Another object of my invention is to produce a machine table which will adjust itself to any vertical angle at which the timber may be placed thus greatly facilitating the Working of the machine as the rollers supporting the timber at the feeding and receiving ends do not need to be adjusted accurately in order to bring the timber into en gagement with the cutter, as is the case Where a fixed table is used.

A further object of my invention is to enable a long timber to be fed on the machine from either direction so that if both edges are to be worked the timber may first be fed through in one direction and then its other edge placed down on the machine and fed in the opposite direction.

My invention is of general applicability though specially adapted for shaping the timbers used in ship building for which purpose it is specially designed and in which it is in constant use.

I attain these objects by the devices and mechanism illustrated in the accompanying drawing, in which Figure l is a plan of my machine. Fig. 2 is a plan showing the roller adjustment. Fig. 3 is a side view of my machine. Fig. 4 is an enlarged side view of the lever for adjusting the angle of one section of the table. Fig. 5 is a front view of mymachine. Fig. 6 is an end view of the swinging cradle showing the Inechanism for adjusting the angle of 'one section of the table. Fig. 7 is a cross-section of my machine on the line 7-7 in Eig. 3. Fig. S is an enlarged longitudinal section of the cradle showing the mechanism for controlling and adjusting the sections of the table secured thereto. Figs. 9 and 10 are views showing the cradle tipped in opposite directions and the table sections arranged for planing a straight side of timber, said timber being fed into the machine in opposite directions therein. Fig.`11 is a similar View showing one table section adjusted so that a con-` cave edge can be planed on the timber, and, Fig. 12 is a similar view showing the adjustment for planing a convex edge on the timbers.

Similar numerals of reference refer to similar parts throughout the several views.

In general my machine consists of a frame having one standard at the front end and two opposite standards at the centers of its two sides. To the front standard is pivoted an auxiliary frame carrying a pair of parallel rollers which may be adjusted in their frame. This auxiliary frame is held in any desired angle to the perpendicular by the adjusting screw joining it to the posts of the main frame. The two side standards support a cradle which is lfree to swing thereon on its horizontal transverse axis and this cradle supports in said axis the rotating horizontal cutter, as well as the upper table. This upper table is made in two similar sections one on each side of the transverse cen ter of the cradle. Each section of the table is supported from the cradle at three points, two near the cutter and one at the center of the ends. These supporting points are all joined together by suitable mechanism pivoted to the cradle and which can be moved as a whole so as to lower one section of the table and raise the other section to compensate for a certain definite depth of cut when the timber is fed in either direction, and also the end supporting point of one section may be separately adjusted on said joining mechanism so that said section can be tipped relatively to the other section Without interfering with or altering the action last above described.

Referring to the drawings the base l of the machine is provided with a pair of tall posts 2 at one end and with shorter posts 3 at its other end, all said posts being properly connected and braced so as to make a strong and substantial main frame. The postsnZ are joined at their upper end by a IOO plate "4 on which degrees are marked on each side of the central point, as indicated in Fig. 5. The end standard 5 extends upward from the base 1 to a point a little lower than the upper table as hereinafter described, and supports the auxiliary frame 7 on apivot 6. The upper end of the frame 7 is provided with a central pointer or indicator 8 which comes into close proximity with the gradations or degrees marked on the plate 4 above mentioned. The frame 7 is controlled on its pivot 6 by means of the screw 9 which engages the swivel nut 10 secured to the frame 7, said screw 9 being held longitudinally in the swivel 11 secured to the post 2 of the main frame. A turning handle 12 is attached to the end of the screw 9. Thus by working the handle 12 the screw 9 will push or pull the frame about its pivot and will alter correspondingly the vertical angle of said frame 7. The guide rollers 13 are mounted in the frame on lines parallel with the central axis thereof being mounted in small angle pieces 14 which are secured to the frame 7 by bolts passing through said angle pieces and slots in said frame so that said pieces 14 are adjustable in said frame. The rollers 13 are allowed a slight movement in the pieces 14 away from the central axis of the frame 7 so as to compensate for any slight irregularity in the thickness of the timber beingI guided by the rollers 13 without pinching the timber between the rollers. A spring 15'keeps the rollers 13 pressed toward the center (Fig. 2). LIt is evident then that a timber fed between the rollers 13 will make any desired angle with the horizontal and that this angle may be kept constant or may be changed intermittently or continuously and that since the cutter is mounted horizontally (as hereinafter described) the bevel cut thereby on the timber will correspond with the angle indicated on the gage and that this bevel may be made in either direction.

The swinging cradle consists of a frame having two side members 16 and two transverse members 17 all securely braced and fastened together to form a strong body. This frame is hung on its central transverse axis from the two side standards 18 which are securedto the base 1 and are braced to the posts 2 and 3. The standards 18 are provided with concave depressions on their upper ends into which fit the semicylindrical brackets 19 of the hanger plates 20 which are letl into and firmly secured to the centers of the side pieces 16 of the cradle. This arrangement allows the cradle to swing on an axis concentric with the centers of the brackets 19. The bearings 21 are secured to the tops of the pieces 16 in such a manner that their centers will coincide with the axis above mentioned. The cutter 22 is mounted on the shaft 23 which is supported in the bearings 21, and is provided 'with a suitable driving pulley 24 or by any other suitable device whereby said shaft and cutter may be rotated. The cutter 22 extends along` the shaft 23 and cuts with its upper horizonvtal edges and fits between the two side members 16 of the cradle. Thus t-he cutter is rotated on a fixed axis and is entirely independent of any swinging of the cradle which supports it.

Referring now particularly to Figs. 7 and S it will be seen that the table on which the work is supported consists of two sections 25" and 26 which are supported from and above the cradle. mally in one plane parallel 'with the cradle and divide on the central transverse axis thereof, being however cut out to allow the cutter 22 to pass through them. They are supported on levers which are connected together in such a manner that if one section 25 is raised a certain distance (parallel to the cradle) the other section 26 will be lowered an equal distance (parallel with its former position) and vice versa. As shown in the drawings the section 25 always remains parallel with the cradle but the section 26 may be tipped in either longitudinal direction and then when it is raised or lowered it moves to a plane parallel -with said tipped position. This is accomplished in the following manner. The section 25 is supported from three pins, two of which 27 are close to the cutter 22, -while the third 28 is located at the center of the outer end of the section. The pins 27 and 28 couple the castings 29, secured to the lower Iside of the table sections, to the arms of the supporting levers. The two levers 30 are fork-shaped in such a 'way that the tines pass to each side of the cutter, one tine supporting the inner end of the section 25 while the other tine supports the inner end of the section 26. The levers 30 are exactly similar to each other and are both mounted on the same rod or pivot 31, and have similar downward extensions 32 joined by the rod' 33. The lever 34 which is coupled by the pin28 to the casting 29, at the end of the section 25, is exactly similar to the lever 30 except that the tine corresponding to the one supporting the inner end of the section 26 is omitted. The lever 34 is supported by the pin 35 in a position corresponding with the rod 31. The lower end 36 is joined to the center of the rod 33 by the bar 37 which extends in both directions beyond the parts 33 and 36 respectively. The levers above described are similar in form and are mounted so that any movement of the bar 37 will make them move together and The sections lie nor-,

will either raise or lower the section 25 parallel with the cradle according to whichever direction said bar "37 may be moved.

The section 26 of the table is supported at its inner end exactly similar to the section "25 by the pins 27 engaging the tines of the levers 30, and since they are on opposite sides of the center rod 31 they will have an equal but opposite movement so that if the section 25 is raised a certain distance the inner end of the section 26 will be lowered a corresponding distance. The outer end of the section 26 is however supported in a slightly different manner as follows: The lever 38 is similar to the lever 34 in its general form and is pivoted from a similar pin 35 but it is forked at its lower end and isvprovided with a pair of inside trunnions 39 (Fig.- 6) which engage between the flanges 40 of the nut 41 which is screwed on the rod42 which is a pivotal extension of the bar 37, the said nut 41 being provided with a handle 43 or other suitable means whereby it is turned so that the distance between the extension 32 and the nut 41 is adjustable by screwing said nut in one direction or the other. The upper end of the lever 3S is similar to the lever 34 but the pin 44 which corresponds to the pin 28 of the section 25 is mounted in the slot 45 in the casting 46 so that any movement of the nut on the screw threaded rod 42 will cause the pin 44 to slide in the slot 45 and will cause the end of the section to rise or lower without altering the position of the pins 27 or affecting in any manner the section 25, and any motion of the bar 37 and its extension 42 will cause the section 26 to rise or fall as a whole parallel to its previous position.`

The motion of the bar 37 is attained by screw-threading its end and mounting thereon the nut 47 having flanges which engage in a slot in the hanger 48 which is securely fastened to the cradle. The nut 47 is also provided with a handle 49 or other suitable means whereby it is turned, and as before indicated any turning of the nut 47 will move the bar 37 and will raise and lower the sections 25 and 26with respect to each other and to the cradle and thecutter. The amount of difference between the levels of the two sections 25 and 26 can thus be regulated by turning the nut 47 and this will be determined by the depth of cut or amount of wood it is desired that the cutter should remove. The higher section of the table will always be the one beyond the cutter in the direction in which the timber is being fed into the machine so that if a timber has been fed from left to right (Fig. 9) it will not be necessary to carry it back again to the end of the machine from which it has'come in order to work on its other face but it is only necessary to turn that face down screw the nut 47 so as to lower the right section and raise the left section 5 and feed the timber back over the cutter in the opposite direction (Fig. 10) 5 thus saving much time and labor in handling the heavy timbers used in shipbuilding. If a concave timber is to be planed then the screw nut 41 is turned so as to shorten the distance between the lower ends of the levers and thus draw down the outer end of the section 26 so that said timber can be supported on both the sections and yet be reached by the cutter 32 (Fig. 11) while if a convex surface is to be planed the nut 41 is turned in the opposite direction and the end of the section "26 raised the desired amount to support the timber (Fig. 12). Thus it will be seen that all the various parts of my machine unite to produce a planer which will plane any bevel to any straight or curved surface, in either direction, and that the supporting table and cradle automatically adjusts itself to the angle at which the timber is fed on the machine, and that the bevel maybe changed as the timber passes through the machine.
