WILLIAM CRAINE, OF BRQOKFIELD, NEW YORK WOODWORKING-MACHINE.

To all 'whom t may concern.' i Be it known that I, WILLIAM CHAINE, a

`citizen of the United States, residing at .Brooklielih in the county of Madison and State of New York, have invented a new and useful WoodworkingMachine, of which f the following is a specification. ,j

This invention relates to wood working machines and more particularly to machines for shaping the ends of boards, scantling, j

poles and other timbers, for use in making splice or scarf joints. j

Another object is to provide a machine of this character utilizing a novel arrangement of saws and burs for producin shoulders or abutinents and tongues at t e ends `of the timbers whereby the said timbers when brought together, `will conceal the interfittingtongiies, thus rendering the joint particularly useful in connection with Afurther object'is `to provide gangs of burs so mounted as to be readily moved into and out of active positions by the operator.

A `further Objectis to provide means fol" limiting (the movement of the stock relative to the burs so that successive pieces of stock will be of the same shape and proportions at their ends.

Vith the foregoing and other objects in proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafterl described and claimed, it being understood that changes in the precise embodiment of `the invention herein disclosed,can be made within the scope of whatis claimed, without de parting from the spirit of the invention.

In the accompanying drawings the j preferred form of the invention has been shown.

one end portion of the feed table or slide which coperates with the stopp Fig. 14 is a perspective view of` a portion of the strue-` ture and showing the guide arm depending` from one of the hinged frames.

`Referring to the figures by characters of reference Ldesignates a supporting structure on whichis arranged a table Q `projecting forwardly beyond the supporting structure and` having a downwardly turned flange 3 along its front edge. Formed in this table near one side of` the `machine is a transf versely extendingslot 4l while located in the table"near the opposite side thereof is a group of f parallel` longitudinal slots 5. Mounted on the table between the slots 5 and the adjacent side of thetable is a gage including a base plate 6 having aniupstanding y flange 7, this flange extending longitudinally of the table and parallel with the slots 5. j The base plate G has a depending flange 8 at its 10, 11 andlQ are detail views ofthe parts of `the stopf Fig. 13 is a perspective view of 60 front end engaging the front edge of the table 2 while a transverse slot 9 isfformed in the base plate and receives a clamping bolt 10 upstanding from the table. Thus it will be seen that the gage can be adjusted transversely of the table.

` A feed table orslide l1 is mounted on the table 2 and is provided, along one side, with an iipstanding flange 12 which is bent downwardly so as to straddle the flange 7, as shown in Fig. 9. Thus the slide or feed table 11 is properly guided duringits movei ment longitudinally of the machine. That end of the feed table 11 nearest the slots 5 is provided with parallel fingers 13 designed to project between the slots Mounted on the table 2 and back of the slots 5 is an angular bracket ll-tl having a slot 15 in its base adapted to receive a clamping bolt 1G whereby the bracket can be held y against movement relative to the table 2. By providingthe slot 15, however,the said bracket can be adjusted longitudinally of j The upstanding portion of bracket ll` is formed` with a longitudinal slot 17 for the reception of a clamping bolt 18 which extends into a slot 19 formed longitudinally within the upstanding ond 20 of the bottom plate 21 of a stop. This 'bottom plate has fingers 22 at :its `free end adapted to extend betwcenthe slots 5 andinto the path of the fingers 13. A longitudinal slot 23 is formed in the bottoni plate 21 and is designed to receive a clamping bolt 24 which extends through a slot 25 in the base 26 of a stop 27. r)This stop extends transversely of the plate lt will be apparent that by mounting the stop in the manner set forth, the bottom plate 21 can be adjustedV upwardly and downwardly by loosening the bolt 18, the stop 27 can be adjusted toward or from the lingers 22 by loosening the bolt 24, and theentire structure can be shifted bodily toward or from the slots 5 by loosening the bolt 16. As shown in Fig. 2, the free ends of the fingers 13 on `the slide or feed table 18 are upturned so as to ride onto the lingers 22 and come against the stop 27. llurthermore these fingers have their free ends folded and provided with upwardly extending ears 28 constituting abutments for stoclr as hereinafter set'forth.

Extending ytransversely within the rear end portion of the supporting structure 1 at the back end thereof is a' shaft 29 on which a frame 30 is mounted to swing. rlhe free end portion of this frame carries a transverse shaft 31 to which is secured a series of burs or cutters 32 designed to move upwardly .into the lrespective slots 5. A pulley 33`is secured tothe sha t 31 and receives motion, through an` endless belt 34, from a pulley secured to the shaft 29. An arched adjustingrod 36 'extends under the frame 30 and is journaled within the supporting structure 1 and this rod is provided with an arm 37 whereby it can be actuated readily for the purpose of swinging the frame 30 upwardly or downwardly. When the frame is swung upwardly, the cutting `disks or burs 32 willmove into and through the slots 5 and against the stoclr which may be supported thereabove whereas, when the frame 30 is moved downwardly, the cutting elements 32 will be withdrawn from the slots 5.

A transverse shaft 38 is ournaled within the upper portion of the supporting structure and above the rear end of the table 2 and this shaftv supports a swinging frame 39 the front or free end of which carries a transverse shaft 40 on which is arranged a series of cutting disks or burs 41. r1hese cutting dislrs or burs are located directly above the lingers 13 or, in other words, are staggered relative to the cutting elements 32. A pulley 42 rotates with the cutting elements 41 and receives motion, through an endless belt or the like, from the pulley 35 hereinbefore referred to, there being suitably arranged guide pulleys within the rear portion of the frame 39 as shown in Fig.2.` This upper `frame has an arcuate guide rod 45 depending loosely therefrom and engaged by an eye bolt 46 which, when tightened, as by means of a nut 47, will be caused to bind upon the rod and thus lock the frame 39 at any angle to which it may be adjusted. As shown particularly in Fig. 2, a hood 48 may be hingedly connected to the frame 39, this hood being provided with angular side wings 49 for supporting the hood in position over the cutting elements 41.

lVhen the hood is not to be used it can be swungbaclr as shown by dotted lines in said Fig. 2. n

lv/When it is desired to form one'end of .a timberwith oppositely pitched tongues disposed in staggered 'relation as shown, for example, in Fig. 7, the burs 32 and 41 are. adjusted toward each other and the timber to be cut is placed on the slide or feed table :11 so that it will abut 'against the upstanding ears 28. r1`he said timber is then yfed forward until the fingers 13 come against' the stop 27. During this forward movement of the timber, it is brought between and against the rapidly rotating cutting elements and 41 and consequently, a

product such as shown in Fig. 7 will thus be produced. Obviously the same form of scarf or splice joint can be produced in other forms of lumber. In the form shown in Fig. 7, two pole sections have been shown with ends shaped in the manner hereinbefore described. lt will be understood'that as soon as the end of the timber has been slotted or tongued in the manner set forth,

the cutting elements 32 can be lowered by rotating the arched rod or bar 36 and, by loosening the nut 47, the guide rods 45 will be loosened and the frame 39 can then be swung upwardly. Thus the cutting elements 41 will be lifted out of engagement with the stock. i

Slidably mounted on the table 2 at one side of the machine is a feed table or slide 50 having an upstanding longitudinal flange 51 along one side thereof while depending from the front end of this feed table o11` slide is a downwardly and upwardly curved flange adapted to engage the flange 3,

thus to hold the table or slide 51 against longitudinal. displacement while permitting said slide or table 50 to be shifted transverselyof the table 2.

A bracket 53 is arranged within the lower vportion of the supporting structure 1 and 5C, is connected to the upperend of the shaft and a pulley 57 is carried by the shaft and is adapted to receive motion through a belt 53 from a pulley 59 secured to the shaft 29U hereinbefore referred to. Saw 56 is adapt'- ed to project upwardly through the slot 4 hereinbefore referred to and back of the slide or table 50.

The frame 55 has an arcuate arm 60 eX.- tending upwardly and `forwardly therefrom and adapted to be engaged by an eye bolt 6l similar to the bolt 46 hereinbefore referred to, a nut 62 being provided for tightening saidbolt upon the `arm `6(),\thus to hold the frame 55 atany angle to which it may be adjusted. Any suitable tightener 63 may be employed for holding the belt 58 taut 'after the frame 55 has beenadjusted angularly. j

The shaft 38 constitutes the fulerum for a frame 611 which overhangs the rear portion of the table 2 and carries a shaft 65 having a saw 66 at its front end and movable to position above the slot if This shaft `65 has a pulley 67 designed to receive motion, through a belt 68, from the pulley 59.

An arcuate rod 69 extends downwardly and rearwardly from the frame 64 and is adapted to be engaged by an eye bolt 70 similar to the bolts 46 `and 61 hereinbefore referred to, this bolt 70 being engaged by a nut 7l whereby the bolt 70 can be tightened on the rod 69 and the frame 64 thus held in any position to which it may be adjusted closed will be the meeting shoulders 72. The

machine which has been described is particularly designed for producing an article such as shown in Fig. 5. In the manufacture of such an article, the timber is placed on the table or slide 50 and with one end projecting past the saws 56 and 66. After the saws have been adjusted toward each other as shown in Fig. 3, the table or slide 50 is shifted transversely of the table 2, thus bringing the end portion of the timber against the saws. produce the shoulder 72 while the` lower saw 5G will cut the bevel at the end of the timber and which forms the free ends of the tongues 73. After the end of the timber has thus been shaped, it is lifted from the slide or table 50 and placed on the slide 18. The cutting elements ll are lifted out of active position while the cutting elements 2:32 are projected upwardly through the slots 5. The slide 18 is then advanced toward the cutting elements, thus bringing the lower portion of the timber into engagement with said cutting elements so that the tongues 73 will thus be produced. The cuttingelements 4,1 are only employed where a double lap such as shown for example in Fig. 7, is to be produced.
