WOODWORKING MACHINE 3 Sheets-Sheet 3 Original Filed Nov. 26, `19550 III {Il} IllilllJll Patented May 15, 1934 UNITED STATES PATENT oFFlCE.
Application November 26, 1930, Serial No. 498,355 Renewed October 11, 1933 16 Claims.
My present invention relates to wood working or routing machines and is especially designed as an improvement on the wood working machine disclosed and broadly claimed in my pending United States application for patent for Wood working machine, Serial Number 414,154, filed December 14, 1929, now Patent No. 1,839,- 599, issued January 5, 1932.
This invention is intended for general use in forming in members to be connected a tongue and groove joint having longitudinal tapered engagement, whereby during assemblage said members have a free and easy movement, the one in respect to the other, except during the latter part of said movement when they engage each other with a wedge action.
The machine illustrated is designed for cutting a longitudinal tapered groove in a member to receive a longitudinally tapered tongue in a member to be connected thereto.
To the above end, generally stated, the invention consists of the novel devices and combination of devices hereinafter described and defined in the claims.
In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.
Referring to the drawings:
Fig. 1 is a fragmentary plan view of a wood working machine having the invention embodied therein;
Fig. 2 is a view principally in section taken on the line 2--2 of Fig. 1;
Fig. 3 is a fragmentary detail View with some parts sectioned on the line 3 3 of Fig. 1;
Fig. 4 is a View corresponding to Fig. 3, with the exception that the sections of the way are locked in neutral;
Fig. 5 is a face view of a piece of work having longitudinally tapered grooves'cut therein by the improved machine;
Fig. 6 is a fragmentary perspective view of one end of the piece of work at one of the grooves; and
Fig. 7 is a fragmentary face view of the piece of Work on which is indicated by broken lines the cut made by the tool and arrows indicating the direction of travel of the piece of work at the time the cuts are made.
The numeral 8 indicates the frame of a wood working machine on the ends of which is a pair of upright cast brackets 9 that carry therebetween a fixed horizontal cross-rail 10. On the top of the frame 8, under the cross-rail 10, is a pair of parallel track rails 11 which extend at right angles to the cross-rail 10.
A reciprocatory carriage 12 is mounted to travel under the cross-rail 10 and is provided with front and rear pairs of iiat faced wheels 13 arranged to run on the track rails 11 and support the carriage 12 therefrom. The heads of the track rails 11 are flat and relatively Wide in respect to the wheels 13 in order to permit said wheels to shift axially thereon during the longitudinal travel of the carriage 12, as will presently appear.
Positive guide means is provided for causing the carriage 12 to travel in a line that extends at right angles to the cross-bar 10, which direction will hereinafter be referred to as neutral, or to travel obliquely to neutral either to the left or the right thereof. This guide means also positively holds the carriage against angular movement in a horizontal plane when travelling either neutral or oblique to neutral. The oblique travel of the carriage 12 is accomplished by endwise shifting said carriage on the track rails 11 during its reciprocatory movement thereon.
Said guide means may take various different forms and, as shown, is a channeled way 14 comprising two longitudinally spaced sections and a pair of cooperating roller-equipped studs 15 arranged to run one in the channel in each of said sections. The way 14 extends midway between the track rails 11 from the front to the rear of the machine and the two sections thereof are pivoted at the same or their rear ends to a channeled bar 16, as indicated at 17. This bar 16 is rigidly secured to the frame 8 and supports the Way 14 with its sections resting thereon for horizontal swinging movement and the axes of the pivots 17 are at neutral or, in other Words, on a line that extends at right angles to the cross-bar 10.
Ihe sections of the way 14, at their front or free ends, are held against lifting movement from the bar 16 but with freedom for horizontal swinging movement by tongue and groove guides 18. The tongues of these guides 18 are formed by extending the bottom members of the sections of the way 14 and the groove for the tongue on the rear way section is formed by notching the rear end of the front way section and the groove for the tongue on the front way section is formed in a block 19 rigidly secured to the bar 16.
Swinging movement is imparted to the two sections of the way 14 by eccentric rollers 20 which work in slots 21 in the bottoms of'said riage 12 A bar. The pivots 23 for the eccentric rollers 20 and their arms 22 are anchored to the web of the bar 16. Simultaneous and like movements are imparted to the eccentric rollers 20 by a long link 24 which vconnects the arms 22 and is pivoted at its ends thereto equidistant from the centers of the pivots 23. The front arm 22 is extended to provide a handle 25 by which the two arms 22 may be manually oscillated.
An opposing pair of stops 26 is provided for limiting the swinging movement of the front section of the way 14, and hence', the rearsection of said way through the connections 20,y
22 and 24. These stops 26, as shown,`are'in the form of lock-nut-equipped screws which have threaded engagement with upstanding lugs 27 on the sides of the bar 16 and with their inner ends arranged to be engaged' by the side flanges of the front sectionofthe' way 14, see Figs. 3 and4.
yThe roller-equipped studs 15 are rigidly secured to and depend from theV under side of the carriage 12 and their rollerswhich turn about vertical axes are arranged to run Yon the inner faces of the side flanges of 'the' sections of the way 14 with a working Vfit and thereby prevent idewi'se or transverse'moveme'nt of Vthe carriage 12 in respect to the wa'y 14j It is important to] note that the distance between the axesof the two rollers of the studs 15 is exactly the same as'lthe distancebetween the axes of the two pivots17. VObviously, when the carriage 12 is positioned with the axes of the -two rollers of the studs iaiignd with' the' axes of th'epivots 17 rno sidewise movement is wimparted to the f carriage 12 when the sections of the'way 14 are oscillated by the eccentric rollers 20. On the other hand when the carriage 12 is'moved into aI position'in which the axes vof the studs 15 are out of alignment with the-axes or tnevpivots 17 anA the handle 25 operated to oscilla'te the sections of*` the way 14 slight sidew'ise'` movement will be impartedV to said'carriagel When thev two sections ofthe way 14 are in true longitudinal alignment or' neutral Vthe carwill'be guided thereby in a line that extends at a right angleto the'cross-.rail 10. On the other hand when the sections of the way 14 are positioned oblique toneutral the carriage 12 will 'be moved endwise either' tothe right or the'leftsof neutral, depending on which side thereof the sections of Vthev wayv 14 arepositioned', during reciprocatory movementof said carriage. By thus guiding the carriage I2 4the same' is` po'sitivelyheld against angular movements in a horizontal plane.
On the front end of the bar 16 is a fixed stop 28 in the form Vof a short post arranged tov be engaged 'by4 the front edge of the carriage 12 atmits transverse Vcenter Vto limit its forward movement .on the rails 1 1. An adjustable stop 29 on the rear end of the bar 16 is provided for limiting'th'e rearward movement of the carriage 1.2 on the rails lill The adjustable stop 29 is inthe form of a fixed post 30 and a horizontal locknut-equipped screwv 31, which has threaded engagfernenttherewith. Said screw 31 extends forward from the post 30 andpositioned to be engaged by the rearv edge of thecarriage 12 at the limit of'its rearward movement. The obj jectI offrnfaking the stop 29:,adjustable is to cause the carriage 12 to stop with the axes of the rollers of the studs 15 at neutral and in alignment with the pivots 17. As the Obliquity of the two sections of the way 1 4 are identical the carriage 12 when said sections are in an oblique position will be moved endwise during the reciprocatory movement thereof. Of course, this endwise movement of the carriage 12 is very slight,` as will hereinafter appear.
'On the front of the carriage 12 is a pair of handle bars 32 by means of which said carriage may be reciprocated. To hold the sections of the way 14 in neutral, there is provided a lockpin 33 arranged to be inserted through aligned holes in the front end portion of the front 'sectionof the way 14 and the bar 16, see Fig. 4.
For holdinga piece of work X on the carriage 12 in which grooves are to be cut, there is provided at the front of said carriage a pair of angleblocks 34 and at the back of said carriage a nut-acting block 35. The blocks 34 are mounted on a rail 36 attached to the front edge of the carriage 12 and held by set-screws for independent adjustments in respect to each other. The nutacting block is mounted on a long screw 37 turnably mounted in front and rear bearings 38 on the carriage 12 and held against endwise movement. On the rear end of the screw 37 is a hand-crank 39 by which the set-screw may be turned. The sliding contact of the nut-acting block 35 with the carriage 12 holds said block from turning withv the screw 37. The nut-acting block 35 is located midway between the blocks 34 land has rigidly secured thereto a spring-iingcr 40 which directly engages the piece of work X.
The machine is equipped with two cutters 41 for simultaneously cutting two grooves Y in the piece of work X. The cutters 41 are of conical formation for cutting a groove having screws 45 forfrigidly securing the samein dify ferent adjustments on the slidesl 44 and said slides are provided with hand-screws 46 for rigidly securing said slides in different adjustments on the cross-rail 10. By adjusting the cross-headsY 43 on the slides 44 the cutters 41 4 may be moved either forward or rearward and set either directly opposite each other to cut grooves of the same length or one in advance ofthe other so as to cut grooves of different lengths, as vshown` inv Fig'. 5. vBy moving the slides 44 on the cross-rail 10 the cutters 41 may be adjusted transversely of the machine in respect to each other and set different distances apart. The motor supports on the cross-heads 43 are mounted for vertical adjustments to vary the depth at which the cutters 41 will cut grooves but for the purpose of this case, it is not thought necessary to consider the same.
Operation It may be assumed that the cutters 41 are adjustable to cut two grooves at the desired places in the piece of work X mounted on the carriage 12 and that said work is forward of said cutters. rEhe operator first moves'the lever 25 into its full line position, see Fig. 1, to position the sections of the way 14 oblique to normal and at the right thereof and then moves the carriage 12, by means of its handle bar 32, rearward to feed the work to the cutters 41. The cutter 41, which is adjusted to cut a groove completely across the work is rst engaged by said work and thereafter the work engages the other cutter 41. This rearward movement of the carriage 12 continues until stopped by the engagement of said carriage with the stop 29 and which movement is suicient to cut one of the grooves completely across the piece of work while the other extends only part-way thereacross.
The obliquely positioned sections of the way 14 cause the carriage 12 to move transversely to the left during its movement from the front to the rear of the machine and thereby cause the cutters 41 to out dovetail grooves in the work of the same width that extend slightly oblique across said work. At the time the carriage 12 is stopped by the rear stop 29, it is positioned with the roller of the studs 15 in axial alignment with the pivots 17 and at neutral.
The operator next manipulates the handpiece 25 to move the sections of the way 14 to the left of normal and during this movement of said sections the sides thereof, with which the rollers of the studs 15 engage, simply turn about said rollers without imparting any transverse movement whatsoever to the carriage 12. With the sections of the way 14 thus adjusted, the operator draws the carriage 12 forward and said way imparts a transverse movement thereof to the left of neutral, which causes the cutters 41 to re-cut the left-hand sides of the grooves and taper the same in respect to neutral and thereby complete the grooves which are longitudinally tapered, as shown in Fig. 5.
During the lateral shifting movement of the carriage 12 iirst to one side of neutral and then to the other, said carriage is securely held against angular movements in a horizontal plane. This is due to the fact that the two sections of the way 14 are always at the same angle to neutral and that the rollers of the studs 15 are always equi-distant from the pivots 17.
From the foregoing it must be evident that the invention herein disclosed is capable of large range of modication within the spirit of the invention herein disclosed and claimed.
