Laim Patent No. 84,637, dma December 1, 186s.
IMPROVEMENT IN RIE:VOII'a'V'IIl'Gv STAY-LOG- FOR CUTTING VENEERS.
The Schedule referred to in these Letters Patent and making part of' the same.
To all whom 'it 'may concern:
Be' it known that I, JOHN N. LYMAN, of the city, county, and State of New York, have invented a new and improved Revolving Stay-Log for Cutting Veneers; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying dlawings, forming a palt of this specification, in which- Figures 1 and 2 are vertical sectional Views of a revolving stay-log, constructed according to my invention, represented at right anglesto each other. Y
Similar letters of reference indicate corresponding parts in both figures. w
This invention consists in the construction of a revolving stay-log, whereby it is rendered in such manner adjustable, relatively toits journals, that an eccentric adjustment to suit logs of different peripherical or perimetrical curvatures may be effected, and whereby a complete revolution is given to the log, thereby giving more time and opportunityto set the knife or out# ting-edge without stopping or checking the motion of the machinery.
The stay-log represented is of the ordinary fonn and construction, except that the holding-bar A is provided at its extremities with cross-pieces a` a, extending transversely across its ends, and which are Jfitted to slide within grooves gg, provided in the faces of anges b b, on the shoulders of journals AB B. 'I
Said cross-pieces a, are secured at any desirable ad-` justment within the grooves g by means of set-screws c, or by any other suitable means,
O is a shaft, passing lengthwise ofthe machine, and
to which the power is applied, and by which the same.
is imparted to the holding-bar A, by means of pinions D D, secured upon the ends of said shaft, and gearing with cog-wheels E Eupen the journals B B of said holding-ban By this application of power to both ends of the holding-bar A, a better result is obtained, by the prevention of torsion, or any tendency thereto, of the said holding-bar.
In the operation of this invention,- the timber or log is first divided longitudinally in two equal parts, as
nearly asis practicable, and the iiat surface of a section, thus' divided, is screwed or otherwise secured to the dat surface of the holding-bar A, substantially as in stay-logs'of the ordinary construction.
The said holding-bar A is then adj usted relative to its journals B B, by the sliding of the cross-pieces a a inward or outward within the groove'g g, to' or.from the axial centre of said journals, so that -the uter or couvexed surface of the log or section'of timber, may revolve with its pen'phery at a more uniform distance from the knife or cutting-edge.
By this improvement much timber is saved which is Aotherwise lost by the employment of the ordinary staylog in cutting veneers from logs whose entire circumferential surfaces are not equidistant from the axial centre of the holding-bar. l u When the section of timber has been turned towards the knife to a degree suiiicient to take off a veneer from its peripherical surface, the motion of the machine need not be reversed, as in the operation of theordinary stay,- log, but its forward motion continued, and the necessary adjustment or set given to the knife, While'the rear or opposite side of the holding-bar A is being revolved upon that side.
By this improvement a better opportunity is afforded for the satisfactory set or adjustment of the knife, and with less consumption of time.
What I claimas my invention, and desire to have secured by Letters Batent, is-
A revolvingstay-log, constructed as described, and
.for the purpose herein set forth.
JOHN N LYMAN..
