UNITED STATES PATENT OFFICE.
EDWIN JONES, OF GREENFIELD, MASSACHUSETTS.
BRAMAH PLANINGr-WI-IEEL.
Specification of Letters Patent No. 16,163, dated December 2, 1856.
To all 'whom 'it may concern:
Be it known that I, EDWIN JONES, of Greenfield, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in Planing-Machines Adapted More Especially to the Purpose of Planing and Edging Clapboards; and I do hereby decla-re that. the following is a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, Figure 1 being a top View of a planingmachine constructed in my improved manner; Fig. 2, a side elevation thereof; Fig. 3, a transverse section in the line x of Figs. l and 2; Figs. 4 and 5, bottom view and section of the Bramah cutter constructed as I employ it; Fig. 6, view of the connecting gearing by which the proper motion is communicated to the feed-rollers.
Like letters designate corresponding parts in all the figures.
I employ a Bramah wheel A, for planing the surfaces: of the clapboards, or other articles; but instead of making it of the form of a disk, I make it somewhat conical, or dishing, as represented in the drawings, and cause its knives to cut horizontally, or at any inclination, if desired, by inclining the spindle E of the wheel, from a vertical position. The wheel is adjusted up or down, in order to dress the articles to the desired thickness, by moving up or down the movable bearings a, a, upon which it runs. It is driven by a band d, passing from a pulley F, on the driving shaft G, to a pulley Z, on the spindle of the wheel. Into a portion of its hub projecting beneath the Bramah wheel, are secured knives M, M (Figs. 4, and 5,) arranged so as to joint or edge the clapboards, or other articles. Thus the articles have their surfaces dressed off, and their edges jointed by a single combined instrument, requiring scarcely more power and no more machinery to drive, than the simple Bramah wheel would alone.
The clapboards, or other articles, are fed along to the planing wheel, upon a platform or a guiding way, B, by means of two pairs of feeding rollers D, D. These rollers are all simultaneously and uniformly driven by gearing arranged in a peculiar manner. A band c, passes from the driving shaft G, to
and around a pulley II, from the shaft of which, by means of beveled pinions b, b, b, Z),
and an intermediate shaft L, the motion is communicated to beveled cog-wheels I, I, situated respectively upon the axes of the lower of each pair of feeding rollers D, D. From these lower rollers, equal motion is communicated to their respective fellows, by means of four pinions c, f, g, 7i., the rst and last of which are on the respective rollers of each pair; and the intermediate ones are mounted in linked or jointed bearings z', z', in the manner substantially as shown in Fig. 6. By this mode of communicating` an equal motion from one roller to its fellow, it is evident that said rollers may be separated to various distances apart, according to the thickness of material fed along, without disarranging the intermediate gearing. The arrangement is also cheap and simple, when the purposes which it accomplishes, are considered; and it is also compact, and consequently can be boxed in, to protect it from the dirt and dust.
rThe upper roller of each pair is mounted in yielding bearings, which are adjustable by means of screws y), p, or their equivalents.
In order to hold the articles to be plane'd, especially light clapboards, lirmly to the planing wheel, I employ pressure-bars C, C, which extend across the articles on both sides of the planing wheel and as near as possible thereto, the dishing shape and inclined position of which enable them to be brought even under the -edges of said wheel, as shown. And the bars are enabled to be brought still nearer to the cutters by chamferi'ng their inner, upper edges, in the manner represented in the drawings. They are provided with arms, an, m, which extend down through bearings, and are made elastic and adjustable, by spiral springs and screws n, a.
I'Vhat I claim as my invention and desire to secure by Letters Patent, is-
Providing the planing wheel with knives for edging, or jointing, the articles, when arranged as a sin'gle instrument and operating substantially in the manner and for the purpose specified.
The above specification of my improvement in planing machines, signed and witnessed this 7th day of July 1856.
EDWIN JONES.
