SUMNER M. BUMP. F SUTSANVILLE, CALIFORNIA.
INDICATOR "mt "EDGING saws;
Application filed February 20, 1922. Serial No. 537,788.
To all whom it may concern:
'Be it known that I, SUMNER M. BUMP, a citizen of the United States, residing at Susanville, in the county of Lassen and State of California, have invented new and useful Improvements in Indicators for Edging Saws, of which the following is a specification.
This invention relates to saw mills and particularly to edgers employing either hand or circular saws.
In the squaring of the edges of lumber it is of the greatest importance that the largest ossible widths be obtained from the log.
eretofore the sawyer hashad to depend. upon his unaided eye to determine the proper line of cut. requently errors oc' cur, resulting either in the waste or spoilage of the lumber through the production of lumber containing knots, which otherwise could have been avoided, or the cutting of narrower widths than was actually necessary. g
The object of my invention is to plainly indicate throughout the length of the log the line of cut of each edging saw regardless of the adjustment of the saws. This I accomplish by the provision of lights so arranged as to cast a line throughout the length of the log, the lights being so arranged that lines cast will correctly indicate theline of cut of each saw, no matter what position of adjustment the saws may occupy.-
One form which my invention may assume is exemplified in the following description and. illustrated in the accompanying drawin s, in whichig. 1 shows a side elevation, partly in section, of a device embodying my invention.
Fig. 2 shows a plan view of the same.
Fig.3 shows a vertical cross sectional view taken on the line 3-3 of Fig. 2.
' Fig. 4 shows a detail sectional view illus trating the connection between the saw-shifting means andthe actuating means for the guide lights.
Fig. 5 shows a detail view in plan of one of the connections between the cables and saw shifting means.
Fig. 6 shows a shiftable lights.
Fig. ,7 shows a side elevation of the same, partly in section. 1
In the form of the invention herein shown,
cable front elevation of one of the 7 indicates a frame for the saws, 8 the carriage frame and 9 an overhead structure. There is a plurality of edging saws 10 slidablymounted upon a shaft 11 carried by the frame 7. These saws are shifted by means of shifting forks 12 which are controlled by levers 13. Connected to each shifting fork is a rigid arm 14 extending to an endless 15 and clamped thereto. These "cables, one for each saw, operate over sheaves 16, four for each cable, so arranged that the cables describe a rectangular figure. The bottom run of the cables extends trans-,- versely beneath the carriage and the upper run extends transversely of the overhead structure. The sheaves at the upper run are double grooved and also carry endless bands 17 corresponding in number to the cables 15. Each band is connected to a frame 18 slidably mounted on a track 19 extending transversely'of the overhead structure. F astened to each frame is an electric lamp 20 extending into a housing 21. The
housing has a narrow, vertical aperture 21 in its front portion. Lying in the same plane as this aperture and some distance therefrom is an arcuate shield plate 22 supported by rods 22*" fixed 'to the lamp housing. This plate has a central vertical slot 23 and extending longitudinally and centrally of the slot is a thin blade 24. The blade and shield plate being positioned some .distance from the aperture 21? and in line therewith will be acted upon by rays of light which are substantially. parallel, and therefore the shadow cast by the blade .24 will be clearly defined. This shadow will fall uponthe log and extend throughout the length thereof. I 7
These lamps are so set with relation to properly indicate the path of cut of the connected saw. Shifting a saw will, through the described connections, cause the lamp tobe moved a corresponding distance in the. same directon. Thus the operator. can al-. ways, determine from the position of the the saws that the shadows cast thereby will related shadow just where a saw will out in any of its positions of adjustment. This enables him to see at a glance whether or not he has chosen the greatest available width of cut and also enable him to avoid knots and other defects in the lumber.
Various changes in the construction and arrangement of the various parts herein shown and described may be made without departing from the spirit of the inventon as disclosed in the appended claims.
Having thus described my invention, what I claim and desire to secure by Letters Patent is:
1. In a saw mill, a plurality of adjustably mounted edging saws, means for feeding a log thereto, means for shifting the saws relatively, a lamp positioned in linewith each saw and connected with the shifting means for conjoint movement with the related saw, and means in association with each lampfor casting a line throughout the length of ithe log whereby to indicate the line of cut of the. saw.
2. In a saw mill, a plurality of adjustably mounted edging saws, means for feeding a log thereto, means for shifting the saws relatively, a shiftable lamp operatively connected with each shifting means for conjoint movement With the saws, ahousing for each lamp, and means on the housing for casting a shadow throughout the length of the log to indicate the line of cut of the related saw.
3. In a saw mill, a plurality of adjustably mounted edging saws, a carriage for feeding a log thereto, means for shifting the saws relatively, a plurality of endless belts extending transversely beneath and above the carriage in front of the saws, each belt being operatively connected with a saw-shifting means for conjoint movement with the saws, a shiftable lamp above the carriage operatively connected to each belt, and means in association with each lamp and casting a shadow line upon the log coincident with the line of cut of the related saw.
4. In av saw mill, a plurality of adjustably mounted edging saws, meansfor feeding a log thereto, means for shifting the saws relatively and a guide lightfor each saw including a housing formed with a narrow, vertical, light-emitting aperture, a slotted plate positioned some distance in front of the aperture and in line therewith and a thin blade extending centrally of the slot in the plate to cast a shadow upon a'log carried by the carriage.
