UNITED STATES "SOLOMON A. VVOQDS, OF BOSTON, MASSACHUSETTS.
IMPROVEMENT IN PLANxNG-MAcHlm-:s-
Specification forming part of Letters Patent No. 146,500, dated January 13, 1874; application filed Oatober 30, 1873.
To all whom it may concern:
Be it known that I, SOLOMON A. Woons, of Boston, in the county of Suffolk and State ot' Massachusetts, have invented certain Improvements in Planing-Machines; and I do hereby declare that the following, taken in connection with. the drawings which accompany and form part of this specification, is a description of my invention sufficient to enable those skilled in the art to practice it.
The invention relates to the disposition of a presser-roll and chip-breaker spring, with refforce them against the lumber upon which the cutter-cylinder is to operate.
In my invention the presser-roll is jonroted to the main frame, and to a cross-bar of the presser-roll frame I fasten plate-springs, to the opposite ends of which is fixed thechipbreaker spring or iexible bar, which acts against theboard between the roll and cutter- Pressing upon each head of this bed` and take out the warp, while the spring bin ation, with the cutter-cylinder, of a presserroll and a spring chip-breaker, located andarsuch presser-roll and chip-breaker.
The drawing represents an organization em- Figure l shows the mechanism in plan. Fig.
c denotes the main frame; b, the cuttcr-cyl bearings` c Yon the main frame a. In rear of The heads e of this frame are pivoted, as seen are pivoted, as seen at h, to the ina-in frame a.
journaled in the heads e.
toward the cutter-cylinder, bear at their ends a metal or chip-breaker spring, w. Between this spring x and the bar i is located the presser-roll Z, the gudgeons of which roll are u u denotethe wei ght-ed levers. These levers are pivoted at h, and, extendingover the cutter-cylinder journals, and, over the hea-ds ofthe presser-roll frame, have upon their outer ends adjustable or sliding weights o, and from each lever, between the weight and the pivot, extends a short arm, p, that rests and bears down upon the head e beneath it, The pressure of the weighted levers is preferably exerted between the presser-roll and the chip-breaker spring, and insures the holding ofthe board to the bed by the pressure of the roll, while the proweighted levers upon the frame bears down the presser-roll, and insures the holding of lthe board to the bed, and the `removal of its warp, and the spring has no agency in this pressure, but simply acts as a yielding resistance to the lifting action of the cutter-cylinder, while by its spring it thus acts at any part of its length, and without necessarily raising thewhole spring. The spring as may beformed by the edge of one long plate-spring, or may, be fixed to the edge of one long spring, instead of to the en ds of the several springs k; and to prevent its being undulyraised in the frame,
or with relation to the presser-roll, a protector or gage-bar, q, is placed over it, which bar is rigid in the frame, and acts as a stop tothe spring, if the spring at any part rises too high,
in which rise it lnight otherwise extend into ATENT QFFIon slown in my application for a United States Patent, led June 19, 1873, and recently allowed'.
I claiml. In combination with the cutter-cylinder, the presser-roll l and spring chip-breaker relatively arranged in the same pivoted frame, and operating substantially as shown and described. c
2. The pivoted frame d, carrying the presserroll and the spring chip-breaker, combined with a pressure device to press the roll against the board, substantially as described.
3. In combination With the pivoted frame roll l, and chip-breaker spring the stop-bar q, arranged substantially a-s shown and described.
