l COMBINED DADOING AND RELISHING- MACHINE.

f Application filed. May 7,

My invention relates to wood-working machines and its principal object is to provide a machine for simultaneously cla-doing and relishing both ends ofsash rails or other pieces of wood.

A further object of the invention is to provide a machine of this character which is automatic in operation and will do the work automatically and accurately. y

It is also an object of the present invention to provide a machine of this type which will operate on both ends of the length of wood at the same time and which is capable of being adjusted to lengths of wood of various dimensions.

`With the preceding and other objects and advantages in mind, the invention consists of the novel combination of elements, constructions and arrangement of parts and operations to be hereinafter specifically referred to, explicitly claimed and illustrated in the accompanying drawing wherein:

Figure 1 is a top plan view of a da-doing and relishing machine constructed in accordance with my invention,v l f Figure 2 is a side elevation of the same,

Figure 3 is a perspective of one of the door or window stiles-A after being operated on by the machine,

Figure 4 is an end elevation of the machine, and

Figure 5` is a vertical sectional view taken on line 5-5 of Fig. 2.

ReferringV to the drawings in detail, wherein corresponding characters of reference denote. like parts throughout the sever al views, the numeral 5 denotes a supporting table including longitudinally horizontal sills 6 and pairs of supporting legs 7. EX- tending transversely of the beam 6 at the ends thereof are plates-8 and 9, the plate 9 being rigidly attached to these sills 6 while the top rails of the frame are tubes 10 which are perforated on their top side to receive around toothed sprocket thereby permitting the plate 8 to be adjusted toward and away from the plate 9. Pairs of bearings 11 are mounted on the

plates

8 and 9 in longitudinal alinement and in which a main drive shaft 12 is journaled, the latter carrying drive pulleys 13 adapted to be driven by a belt from any desirable source or power, not shown. Journaled in the bearings 11 on the plate 8 and through which the 'shaft 12 passes is a relatively short tubular shaft 13a 1924. Serial N0. 711,728.

having driving connection with the shaft 12 by means ofr a spline 14. Journaled on the

plates

8 and 9 are horizontally disposed shafts or stocks 15 carrying rotary bits or relishing tools 16 at their inner ends. The opposite ends of these shafts or stocks 15 are provided with pinions 17 which are driven by drive pinions 18 fixed to the shaft 12. Also journaled on the

plates

8 and 9 and disposed horizontally at the forward ends thereof are shafts 19 carrying cutter or dadoing heads 20, these shafts 19 being disposed at right angles to the shafts 15. In order to drive the da-doing heads 20, drive belts 21 are engaged with the shafts 19and drive pulleys 22 fixed to the main drive shaft 12.

In order to shift the plate 8 toward and away lfrom the plate 9 the following mechanism is provided: Depending from the plate 8 are bearings 23 in which a shaft 24 is journaled, the latter carrying at its endsV sprocket or round toothed gears 25 which engage holes drilled in the upper face of the tubes that also act as ways or supports or sills. It follows that upon rotation of the hand wheel 28 the shaft 24 will be rotated, thereby causing the sprockets 25 to'traverse the tubular ways 10 to shift the plate 8 laterally on the tubular sills.

Journaled in the table 5 and below the sills 6 is a longitudinally extending shaft 31 carrying disks 32 at the ends thereof and a relatively large pinion 33 adjacent one end thereof. A small shaft 34 is journaled in the table 5 below the shaft 31 which carries a drive pulley 34 driven by the drive belt 35 from the shaft 12. A small drive pinion 87 is also fixed tothis shaft 34. Jou'rnaled in the frame 5 and in horizontal alinement with the shaft 34 is a shaft-38 having

pinions

39 and 40 fixed thereto; the pinion 40 meshes with the pinion 37 while the pinion 39 'meshes with the pinion S3 lto drive the shaft 31.

Extending transversely of the sills 6 at the ends thereof and projecting outwardly from the forward side of the table 5 is a pair of guide rails 41 upon which channel-shaped slides 42 are mounted for reciprocatory movement. Fixed to the upper faces of the carriages 42 and extending longitudinally across the top of the table 5 is a work carriage 43. The upper face of the slides-42 are formed with longitudinal grooves which Cil gun

are enlarged at their bases and receive the heads or bolts 45 carried by the'ends of the work carriage or carrier 43. Nuts 45 are threaded on the upper ends of these bolts which are adapted to be loosenedto permit the bolts to be shifted to any position in the slots to adjust the carriagev or work carrier' 43 relative to the slides 42 to accommodate door or window stiles or other' wooden'members of various widths. Eccentrically conne'cted with the disks are pitinen 46 having operative connection with the slides as indicated at 47.

Fixed to the opposite' faces ofthe

plates

8 and 9 and disposed between the carriage or work carrier=43 and adapted to support theends of the stiles or other work indicated at' W are angle irons 4S, the latter being secured to the

plates

8 and 9 by means of slot 4or bolt connections 50 to permit these plates tombe adjusted vertically to accommodate wood of various thiol-messes.

Fixed to the carriage or worl; carrier 43 at its longitudinalY center and extending at right angles thereto is an arm 5l which underlies the work and terminates in an upstanding abutment 52 at its inner end adapted to engage the worl to pull the same way from the relishing tools and cla-doing headsv as the work holder or carriage moves away from the latter.

The operation of the machine is as follows: The'drive shaft l2 being driven from any suitable source rotates the relishing bits and da-doing heads and through the medium of thev gea-ring above mentioned reciprocates the carriage or carrier 43 toward and away from the relishing bits and cla-doing heads. As the' carriage moves toward the relishing bits and da-doing` heads the work resting on the angle' irons 48 is moved into engagement with these tools and remains in such position long enough for the ends of the wood to be chippedolf or da-doed and at the same time the relishing bits perform the relishing or grooving of the work. As the carriage or work carrier 43 movesaway fromthc tools thework is engaged by the abutment 52 and moved outwardly away from the tools to kpermit the operator to remove the same from the machine and place a new piece of work in position for operation.

It is understood that the form of' my inventionV herein shownand'described is to be taken as a. preferred example of tlie same, and that variouschanges inshape, size and arrangement ofpa'rts in ay be resorted to without departing from the spiritv of the inventionA or the scope of the subjoined claims.
