SAWING-MACHINE.

To all whom it may con/cern.-

vBeit known that I, GEORGE MoRRIs, a citizen of the United States, residing atFruithurst, in the county of Cleburne, State of Alabama, have invented certain new and useful Improvements in Sawing-Machines; and I do hereby declare the following to be a full,

which is being cut afterit is released by the person feeding the machine.

f Other objects and advantages will `be ap parenti-rom the following description, and it will be understood that modificationsof the specific construction shown may be made and any suitable materials may be used without departing from the spirit of the'invention. .Y

In the drawings forming a portion of this specification, and in which like characters of reference indicate similar parts of the several` views,.Figure 1 is a side elevation ofthe present invention. Y Fig. 2 is a transverse section takenjust forwardly of the saws on line 2 2 .of Fig.- 1. Fig. B'is a top plan view. Fig. 4 is a section taken on line 4 4 of Fig. 2. Fig. 5 is a detail section throughone of the sawheads, taken on line 5 5 of Figs. 2 and 4. Fig. 6 is a transverse section'of one of the bearings, taken on line 6 6 of Fig. 2.

Referring now to the drawings, the pretsent invention comprises a supporting-frame 6, upon which there is mounted a bed-plate 9.v The plate 9 is provided witha plurality of longitudinally-extending slots 10,1Which open through the upper and lower faces of the plate and which extend parallel to each other and at an angle of approximately forty-ve degrees to the horizontal faces of the plate. A second series of slots 1 1 are formed through the plate forwardly of the slots 10 these slots f 11 being similar to the slots 10, but extend ing at an angle opposite to that of theslots' Specification of Letters Patent.

Application ned. March 8,1905. serial No. 248,976..

Patented March v1e, 1906.

' 1 0, and the slots 11 are so disposed that the openings of the slots through the faces of the bed-plate 9 aline in pairs longitudinally ofv the plate.

Disposed in the frame beneath the plate 9 thereis a bearing 12, which extends at anangle to the plate,and j ournaled in this bearing there is a'shaft 1 3, which is also j ournaled in a similar bearing 14, disposed at one side of the frame, the shaftextending outwardlyl of the frame and being arranged at its outer end for connectionwith a source of power to be revolved thereby. The shaft 13 slants downwardly toward its outer end, as shown, and extends at right angles to the slots 10, its upper end intersecting the planes of these'slots, and formed adjacent to the upper end of the shaft thereis a laterally-extending flange- 15. A circular saw 16 is provided and has'a central passage in which the shaft is engaged, said saw resting against the flange 15. En-

.gaged with the shaft beyond the saw 1 6 thereV is a collar 18, and resting against this collar there is a second saw 19, which is also engaged with the shaft. A third saw 20 is also engaged with the shaft and is held in spaced relation to the saw 19 by a collar 21, which is similar to the collar 18 and which is engaged with the shaft between the saws. The vshaft projects beyond the saw 20 and hasl engaged therewith a cap 22 to prevent disengagement of the saws and collars from the shaft. j

lThe saws 16, 19, and 20 are so spaced andso disposed that they lie in the slots 10 and extend beyond the upper face of the bed-plate 9, the'slots'l() being equal in number to the saws, as shown. The three saws are' of different sizes, the saw 16 being the largest, while the saw 20 is the smallest, and the proportion is such that the edges of the saws which project through the slots lie in a common horizontal plane.

A second shaft 23 is journaled in bearings 24 and 25, which are similar to the bearings 12 and 14, the shaft 23 being disposed for- 4wa'rdly of the shaft 13 and being -disposed the planes of the saws 16 and 20, 19 and 19 and 16. and 20 intersecting at the upper surface of the plate-9, and the saws project a suflicient distance above the plate 9 to cause the planes of the saws 19 and 20 and those of the saws 19 and 2O to intersect above the plate.

It will thus be apparent that a board brought into engagement with the saws will be cut diagonally in One direction by the saws Of the shaft 13 into a plurality of strips which will have the form Of a rhomboid in cross-sections and that these strips will then be cut by the saws of the shaft 23, the result being a plurality Of cross-sectionally triangular strips. An edge-guide 24 is adjustably mounted upon the bed-plate 9, and mounted rearwardly of the saws there are a pair of vertically-spaced guide- rollers 26 and 27, the latter being disposed with its upper portion in a slot 28, formed transversely through the bed-plate 9 and projecting above the upper face of the latter, and these rollers receive therebetween the board tO be cut. The roller 26 is journaled at its ends in brackets 29, disposed one at each side of the bed-plate 9, and journaled transversely between these brackets rearwardly of the rollers there is a stop 30, which consists of two arms 3l and 32, extending at an angle to each other, and this stop is pivoted at the meeting-point Of its arms and is movable upon its pivot tO bring the free end Of its arm 32 into and out Of engagement with the bed-plate, in engagement with which it is held normally by gravity. It will thus be seen that when a board is being sawed the free end of the arm 32 will rest thereupon and that when it passes the stop the arm 32 will come into engagement with the bed-plate and Iwill lie rearwardly of the board to prevent its being forced back by the action of the saws.

The bed-plate 9 is removable, and the bearings 12, 14, 24, and 25 are so arranged that the shafts may be easily disengaged therefrom fOr-the attachment of different-sized saws thereto for sawing strips of different sizes, and it will be understood that correspondingly-slotted bed-plates will be used in connection with the different-sized saws.

The bearings each consist Of two hinged sections 33 and 34, provided with channels 35, which are semicircular in cross-section and which coperate tO form the shaft-receiving passages. The sections 34 are provided with laterally-extending attaching-plates 36, secured to legs Z, which form a portion of the frame 6, while the sections 33 are provided with laterally-extending plates 37, which lie upon the plates 36 when the bearings are in position tO hold the shafts therewithin, the plates 36 and 37 being held in engagement with each other by a thumb-bolt 38, engaged therein.

The feeding-roller is run by friction, thereby making it adjustable without having tO stop the mechanism. The shafts of the saws are adjustable, so that strips of any size and angle can be cut.

That is claimed is- A machine Of the class described comprising a frame including legs, a slotted bedplate removably disposed upon the frajnlc, bearings secured to the legs, each Of said bearings including a section having a laterally-extending attaching-plate, and a section hinged to the first-named section for movement into and out of position for coperation therewith tO receive a shaft, the second section having the plate thereof arranged to rest against the attaching-plate when said section is in operative position, means engaged in the two plates for holding the sections in operative position, shafts removably ljournaled in the bearings and intersecting the planes Of each other at one end, said shafts having flanges thereon adjacent tO said ends, saws engaged with the shafts, spacing-collars engaged with the shafts between the saws Of each shaft, one

saw Of each shaft resting against the flange thereof, and caps removably engaged with the shafts and arranged tO hold the saws thereupon, said saws projecting through the slots of the bed-plate.

In testimony whereof I affix my signature in presence Of two witnesses.
