ENDLESS CHAIN BED FOR WOOD WORKING MACHINES. I
No. 275,213. Patented Apr. 3, 1883.-
[Ni/EMMY -/W WITNEEEEE UNITED STATES P TENT OFFICE.
LUOIUS P. HOYT, OF AURORA, ILLINOIS.
ENDLESS-CHAIN BED FOR WOOD-WORKING MACHINES.
SPECIFICATION forming part of Letters Patent No. 275,213, dated April 3, 1883.
Application filed January 24, 1883. (No model.)
To all whom it may concern:
Be it known that I, L. P. HOY'I, of Aurora, Illinois, have invented certain Improvements in Snrfacer Chain-Beds, which invention relates more especially to the construction of the lags or slats which, jointed by the links, form the traveling bed of a wood-workin g machine.
It further relates to the surface construction of the stationary bed which forms the support for said lags.
In the drawings forming part of this specification,Figure l shows't'hechain-bed and stationary bed arranged under the surfacing-cylinder of a wood-planer. Fig. 2 is a plan view of the under side of one of the slats or lags. Fig. 3 is across-section to line as x of Fig. 2, somewhat enlarged. Fig. 4 shows a plan or face view of the stationary bed.
Like letters of reference indicate like parts.
The object of my invention is to provide a good bearing-surface of the lags A upon the stationary bed B to reduce friction and to'prevent uneven wearof the lags A and stationary bed. For this purpose I provide the cast-iron or cast-steel lag A, at its bearing-surfaces, a a, with one or more slightly-tapering notches or recesses, d d,which may be formed in the ca ting, or may be otherwise inserted, if so pre ferred. These recesses are then filled with antifriction metal 0 0, preferably an alloy of not too brittle a nature. After pounding this antifriction metal tightly into the cast-iron recusses the surfaces are planned as usual to secure even thickness of the lags.
The stationary bed Bis provided with a steel rail or plate, b, to prevent uneven wear, and to provide more particularly againstwearing hollow under the cutting-cylinder. The face of this stationary bed, Fig. 4, may also be provided with a number of recesses, d, similar to thosein the bearing-surfaces of thelags. Holes may be drilled into the steel rail b, and all of these holes and recesses are filled with antifriction metal 0, as shown above.
The cast-iron lag is greatly injured by particles of sand or dirt carried along by the stand to be planed while traveling along the stationary bed. It will soon become rough. attrite,uueveu,inaccurate. Allof these-qualities will exaggerate by longer use untilthe lag is entirely unfit for further use, worthless.
The anti-friction metal fillings 0 con my'improved lag, while procuring a better frictionsurface by themselves without affecting the strength of the lag,will embed such particles of dirt and prcventtheir harming the cast-iron surface portion of the lag. After a short time the anti-friction metal will fill up the pores of the respective surfaces, and together with the lubricating material will form an unctuous film, covering the bearing-surfaces of the traveling lags, as also the stationary bed B.
I (lo not deem it necessary that both the travelinglagAand the stationary bed B should be provided with anti-friction metal fillings 0, though this might be done,if so preferred.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
1. The lag A of a traveling bed, provided at its bearing-surfaces a a. with one or more recesses, d d, which are filled with anti-friction metal a c, for the purpose as described and set forth in the specification.
2. The stationary bed B, provided at its upper bearing-surface with holes or recesses filled with anti-friction metal, for the purpose as specified.
