A, je] .form W. EvILsIzER, or` IANTHA; MI'SSO-RI' 'I To'ajZZ 'f'whol'lm may concern:
Beit knownthat I, JOHN- W. EvILsrznm.
a c'itizenofl the United States, residingat lantha, lin the' county of Barton, State of Missouri, have invented `a new and useful llVloi-tisiiigMachine; and I do lhereby .de-
clare the following to be a full, clear, and;
exact "description of the invention, such as ywill enable others skilled inthe art to which it l.app'e'rtains'to make and -use the same.
This invention relates to. theartlof 4wood working,
improved and practical mortising machine,
and an y,objectzof ythe invention is to provide an oscillatory mortisingtool uand support therefor, whereby apiece of timber may be mortised. f
Another :object of the invention is the pros vision of Amea-ns mounted inlguides to be rec1procated,rand provided with means for e holding a piece of timber, whereby the timber may be Ibrought into engagement with the mortising tool. A further object of the invention is to provide means for holdingthe reciprocating means vnormally in a raised position.
In practical fields the details of construction may necessitate alterations falling within the scope of what is claimed.
The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.
In the drawings:
Figure 1 is a view in side elevation of the improved machine constructed in accordance with the invention.`
Fig. 2 is a plan view of the machine.
- Fig. 3 is a vertical sectional View on line 3-3 of Fig. 1.
f Fig. 4 is a detail perspective View of the s oscillatory mortising tool.
Fig. 5 is a view invrear elevation of the mortising tool. I Referring more especially to the drawings, V1 designates a stand or pedestal having a base 2, which may be secured in any suitable manner to the floor or the like, and mounted upon the stand or pedestal is a bed plateh. lSecured by bolts 11 upon the bed plate is a supporting 'bracket -5 provided with a reduced upper end 6. An oscillatory tool holder 7 is provided, and which comprises a substantially circular head 8 and an elongatedggarm 9. The rear face of the head '8 is `provided.with a segmental recess 10 for the reception of the reduced end 6 of the e ASp eciv'licaton of Letters Patent.
and more especially to ta simple,
Patented June 3, 1919;
1 Application inea rebrurya, 1917.5' seril No. 146,139;
A supportingbracket,"therebeinga pin 11 extending through the reduced end 6 and the head 8, to pivotally mount the tool holder, whereby the samemay be oscillated. The peripheral edge of the head 8 is provided with a pluralityof angular. recesses 12,A in
which the cuttlng tools-13 are 'detachedly secured by the .screwsy '14.1' It is to be noted that the tools are so arrangedon the head vof the holder, as to gouge or cut a segmental mortise opening-in 'ai piece of timber, when the timber is brought in contact Iwith thetools, provided however, the holder penetrates thev timber a's far as the. pivot of the holder. However, should the timber be wide .enough to permit the holder to, enter the same beyond the pivot, the timber will .be
e providedwith a mortise edge walls, which are, connected by a segmental arch wall.l Should the piece v of timber be narrow* enough to -permit having parallel side* the tool holderto cut through, a rectangular mortise opening would be provided. ,The bed plate 1s providedwith an opening 16, and downwardly extendingl arms 17 vwhich .pro'ect downwardly from the bed plate adjacent the ends of the opening 16. v The inner faces of the arms 17 have guideqb's 18, whichare engaged [by the guide grooves I-19A of the longitudinal opposite edges of the vertically reciprocating: carriage 20. The upperend of the carriage 20 is provided with a timber holding member 21 provided withthe lugs 22 to penetrate. the piece of timber, as shown at 23, in order t0 hold the same in place. Projecting. laterallyA fromfone face' of the timber holding member 21 areJ the firms 24,
' which receive the timber clamfs orrods 25, Y there being hand nuts 26 threaded -upon the clamps or rods 25, for holdingthe right ane gle extending ends 27 tight against the under surface of the piece of timber, to se` curely hold the saine' in place while being mortised. A coil spring 28 is provided, and has one end connected lower end of the carriage, and its other end connected at 30 to the under .',face of the bed plate, thereby holding the carriage :normally in a raised position, there being 'a pin" 31 carried Iby the carriage to engage the' under face of the bed plate to limi-t the carriage to its uppermost position. 'Pivoted upon anv arm 32 as at -33 is a lever 34, one end of which is'provided with a roller 35 to engage under the bed plate. By grasping the handle -end of the lever 34 .and moving the same to a screw29 of the downwardly. the carriage may be moved downwardly, lo bring the piece ot timber in contact with the tools ot' the oscillating tool holder, and as pressure is maintained upon the lever 34.11 mortise opening will be out through the piece of timber. Mounted in suitable bearings 315 of the bed plate is a shaft 3l', having a disk wheel 38 on one end, and idle and fast pulleys 3 9 and 4Q upon the other end. Connected eccentrically at ell to the disk wheel is a pitman rod l2, the other end ot' which is pivotally mounted upon a reduced end i3 of the pin Il, the larger por tion l5 of which extends through the segmental slot I6, in order to guide the tool holder' and its arm in their oscillatory movements. The reduced portion 4:7 of the pin Je passes through the lower part of the arm S) of the tool holder, so that. the arm will pivot upon the pin. The pin 44 is provided l with nuts IS and i9 upon both ends, thereby holding the pin in engagement withthe slot lli' and the pitman in position. The usual form of `belt shifting device is mounted in bearings of the bed plate for shifting the belt 5l from the idle pulley to the fast pulley and vice versa, so as to impart movement to the shaft 37, which, owing to the disk wheeland pit-man, imparts an oscillatory movement to the tool holder. The belt 5l may receive power from any suitable source not shown.
The invention having been set forth, what is claimed as new and useful is:
l. In a mortising machine, a bed frame having a guide, a carriage reciprocating in said: guide and havin" a work holder at its upper end, said work holder comprising atimber holding member extending transversely of the upper end of the carriage andprovided with lugs to penetrate the piece of timber to be he1d, said timber holding member having upwardly extending arms, a pair of screws mounted in said arms and having at their forward 'portions downwardly right angle extending parts terminating in inwardly extending lugs, and means threaded on the screws to draw the right angle extending parts and lugs against the forward and underface portions respectively of the piece of timber, wherein' the Iii-st lugs are held in penetrating Contact with the timber.
2. In a mortising machine, a bed frame, an npstanding bracket thereon having on its upper-edge a projection, a mortisingtool having one face chambered out to receive said restricted projection, the opposing walls of the chambered out portion adapted to co'- operate with said projection to limit the tool in its oscillatory movement, means to pivot the tool'to the projection. said bracket having an arcuate slot concentric with the pivot of the tool, the lower end of the tool having nzeans engaging in said slot for guiding the tool, and a reciprocating member connected to said last named means to oscilla'te the tool.
In testimony whereof I have signed in v name to this` specification in the presence ot' two subscribing witnesses.
