" GEORGE J. HULBERT, OF SEATTLE, WASHINGTON.
'massa To allwhomtmay concern:
Be it known that I, GEORGE J. HULBERT, a citizen of the United States, and residing at Seattle, in the county of King and State of Washington,` have invented certain new and useful Improvements in Adjustable Saws, "of Whichthe following is a specilication. v
This invention relates to improvements in devices for adjusting saws and particularly for adjusting a plurality of circular saws as are used on edging machines.
An Object of the invention is to provide a device for adjusting the position of saws while rotating, the adjusting means being carried by the machine structure.
Another object of the device is to mount the adjusting means in such a way that it will not come in contact with the work on the machine.
With these ob'ects in view, the invention also comprehen s other objects which are articularly pointed out in the following escri tion and claims.
Figure 1 is a plan view of an edging machine with the improved adjusting means attached thereto.
Fig. 2 is a front elevation of the machine.
Fig. 3 is a sectional view on line 33 of Fig. 1. i
Fig. 4 is a sectional view on line 4 4 of Fig. 3.
ig. 5 is a detail section showing the adjusting handle.
1 indicates the table of an ordinary type of edging machine, which is provided with bearings 2 for a slotted arbor 3, and a longitudinal groove 4 in the front edge thereof ada ted to receive o erating handles.
5 in icates the slot 1n the arbor 3, and said arbor has a plurality of saws 6 slidably mounted thereon, and provided with lugs 8 extending into the Openings 7 in the saws, and engaging in the slot 5 in the arbor to reventrotation of the saw On the arbor.
he arboris also provided with a central bore 9, in which is mounted annularly slotted rings l0 provided with lugs 11 extending into slotl 5 and having a bifurcated end portion to engage with the lugs 8 on the saws. Disks 12 are mounted in the slotted portion of the ring and are provided with a series of holes 13, spaced from the center thereof, and eyes 14 on either side of the disks in the center portion. The
rings and saws are both adapted to `rotate tion with the rings. Cables 15 are secured to the eyes of each disk and extend through 4the holes. in theother disks beyond the end end of the arbor where they are passed over `"aseries' ofpulleys 16, and then are passed over pulleys 17 secured to the table of the machlne. As shown, the cables extend in opposite directions from each side of the disks, passing over the pulleys 16 at Opposite ends of the arbor and then extending parallel to each other to the pulleys 17, after which they are brought toward each other and secured to eyes 19 on adjusting handles 18, which are slidably mounted in the groove 4 in the table of the machine.
Along the upper edge of the table is formed a series of indentations 2() to provide a scale, so that the distance between the saws may be indicated thereon by the rela tive positions of the handles.
A pulley 21 is mounted near one end of the arbor, and adapted to receive a belt 22 through which the'power for driving the saws is transmitted.
In the operation of an edgin machine with the above described saw adjusting devices, it will be obvious that the saws may be adjusted during the rotation thereof, simply by moving the handles in the slot 4 of the table, so that the handles indicate on the scale, the desired distance between saws. InV the movement of the handles, the cables' 15 are moved therewith, and transmit the motion of the handles to the disks, which will be moved longitudinally in the arbor, and through the rings will move the saws to the desired position.
What I claim is 1. In an edging machine, the combination of a table, a slotted arbor rotatably mounted "thereon, having a longitudinal bore formed therein, a plurality of saws slidably mounted on the arbor, and having lu s formed thereon, and extending into the s Ot in the arbor, a series of rings in the arbor having an annular groove therein, and a projecting lug adapted to lit in the slot in the arbor and engage the lug on said saw, disks mounted in the rings, and means for moving the disks to space the saws a predetermined distance apart.
2. An edging machine, comprising l. table,
Specification of `Letters Patent. Patented Sept. 13, 1921. i Application inea septemter 24, 1920. serial No. 412,435. i'
a slotted arbor rotatably mounted thereon, and formed with a-'ilongitudinal bore, a-plu# rality of saws slidably mounted on the arbor,
' 1 rings mounted in the bore, formed with lugs through the liolesin lthe other disks vbeyond the end of 'said arbor, pulleys mounted on the tablethe edge of the ltable being formed :with a groove and handles mounted in said grooye' the ends of said cables Vextending 'aou-njd and passing over the cured to the handles. e
* edging machine -eomprisinga table,
pulleys and sea slotted arbor rotatably mounted thereon and formed with a longitudinal bore, a pluralityof saws slidably mounted on the arbor, elements mounted in the bore, and connected with the saws, and means for moving the elements.
4. An edging machine comprising a table, a Vslotted arbor rotatably mounted thereon formed with a longitudinal bore, a plurality of saws slidably mounted 4on said arbor, and means mounted within the bore and conneoted with the saws, and controlled from a remote point for moving the saws on the arbor.
'In testimony whereof I atlix my signature.
