FRANK B. PHILBRICK, OF WATERVILLE, MAINE, ASSIGNOR OF ONE-HALF TO 4 FRANK B. XVEBBER, OF SAME PLACE.

CYLINDER PLANER.

SPECIFICATION forming part of Letters Patent No. 397,246, dated February 5, 1889. Application filed August 1 l 1888. Serial No. 281,699. (No model-) To all whom it may concern:

Be it known that I, FRANK B. PHILBRICK, a citizen of the United States, residing at Yaterville, in the county of Kennebec and State of Maine, have invented certain new. and use ful Improvements in Cylinder Planers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to cylinder planersof that class commonly called buzz planers, which consist of a cyliiiider-head having a table on each side whose upper surfaces are approximately on a level with the upper surface of the cylinder-head, one or both being adjustable vertically. They are used for planing the surfaces of short pieces of lumber, rabbeting door-frames, and for other like work.

My invention is directed to the production of a planer which shall combine cheapness, simplicity, and strength, and particularly to an improved construction of the bearings by which the cams which raise and lower the tables are connected with the standard and the brackets on which the table rests. Hitherto these hearings or parts of them have been detachable and separate parts of the machine, and, being constructed in the ordinary form, they were necessarily attached to the standard by bolts or otherwise. By the use of my improvement I am enabled to cast the standard and its bearings all in one piece, and in like manner the bed and its brackets and bearings are also cast in one piece, thus saving much expense in finishing many parts and making my machine very solid and durable.

My invention consists, essentially, in forming the standard and the bearings integral. The latter, instead of having a circular opening, as usually made, are open at the top for a space of less than the sen1i-circu1nference of the hearing. The brackets and their bearings are also integral and have a similar constrnction, except that the opening is downward, the cams being sufficiently eccentric so that they can be slipped laterally into place, and when turned slightly will be locked in all directions.

The invention also consists of the various combinations of parts, as hereinafter set forth in the claims.

In the accompanying drawings I illustrate a machine which embodies my invention, although I do not wish to limit myself to the exact features here shown.

In the drawings, Figure 1 is a perspective view. Fig. 2 is a side elevation. Fig. 3 is an end elevation. Fig. 4E is an enlarged section on the line a: a: of Fig. 5. Fig. 5 is a section on the line so a: of Fig. 4.

The standard or support A is provided with the usual base. The lower portion has its four sides continuous. Near its upper end the sides diverge to a considerably greater width than at the lower part, and they also extend outlengthwise of the machine to form the upper bearings, B 13.

All the bearingsten in numberare cast in one piece with the standard. These consist of the bearings C for the cylinder-head at the extreme upper and central part, four bearings, 13 B, two on each side and near the top, and the four bearings B B near the bottom. The upper bearings B do not form complete circles, but they are open at the top for a space of less than a semicircle. They present in section the figure of a circular segment greater in area than half a circle, with the top portion cut away; The lower bearings have a similar opening at the top, except that they are made, preferably, as half-bearings, or nearly so.

The two tables 0 O and their supportingbrackets F F are cast all in one piece, including the four bearings in each bracket. These brackets have a general triangular shape and are placed one under each side of its table, and the lower ends draw together or approach each other to adapt themselves to the width of the standard. The upper bearings f f on the brackets are similar in construction to the bearings B B, except that the segmental opening is downward instead of 5 upward, and the two lower bearings are in the form of a half-circle, or they may be made less than a half-circle.

The upper bearings, B and f, are adapted to fit the cams D and D, which are identical 10o in form. Each of these cams is formed of: a cylindrical bearing, d? and (7 (see Figs. 4 and 5,) the outer bearing, fitting the bearing B in the standard and the inner bearing, (1, fitting the hearingf in the bracket. These two cylindrical portions of the cam are formed integral and are eccentric as to each other, lapping, as here shown, smnething less than one-half of a circle. Theamountwhich these circular sections overlap each other or the solid portion which joins them, is about equal in extent, as here shown,t:o the open spaeelc't't in the bearings, that when the centers of the cam are in a vertical position relative to each other, and the hearings are in a like position, the former can he slipped endwise \Yhen,how-

through the latterintoposition. ever, the cam is turnedv slightly in either direction, the lateral outer surface of the inner section or hearing'eomes against the inner edge of the hearing ll of the stamlard and the inner lateral surface of the outer section, (I comes against the bracket. It. will thus be seen that when the cams are slipped in in a 'vert ical position and then slightly turned they are locked against any lateral pressure in both directions, as well as any horizontal or vertical pressure.

The lower cams are similar in form to the upper ones and are titted to the half-bearings .3 and f. Each pair of cams on opposite sides is united by a shaft or arbor, L, (see I? g '11,) the shaft which unites the lower cams being much shorter than those which join the upper ones. Each shaft has formed integral with it, as here shown, a short arm or lever, (1 which pro j ects horizontally outward when the tables are raised, and the ends of the arms, which are vertically over each other, are connected by a link, E.

To the lower can], D at one side of the m aehine, is attached the hand-lever G. The lever is secured by passing through a slot in the face of the cam to which it is bolted. The lower end of the lever G, which is bent to occupy a suhstantially-horizontal position, .is provided with a counter-weight, G. On the upper end of the lever G is a fixed handlc, g, and a pivoted handle, g,arrangcd side by side, in the usual manner. A spring, g is inserted between them at their upper ends and acts to force them apart. A segment, ll, is pivcted, as here shown, to the outer section of the cam I) and passes through openings in the handles g and g.

The opening in the pivoted handle 9' cut away to form two pinching edges or surfaces, one, above the segment and on the outside of the handle or the side farthest from the spring, and one, g", on the under side of the segment on the inside of the handle. At the end oi the segmenttherc is a hook or stop to limit the motion of the lever.

To the cam l), which supports the back table, there attached a short arm, I, to the end of which is pivoted a nut, i. A screw,.J,

passes through the nut i, the end of the screw brackets.

being secured to a stud, J in such a manner that it is eapableot being rotated. The stud J is pivoted. to the side of the machine and the screw .l provided with a hand-wheel, .l.

The machine is made up and may he put ttj gether in the following manner, namely: The hearings havingbemi properly faced and turned, the upper hearings in each bracket are placed in position in a vertical plane above the bearings in the standard. The upper cams are then slipped in endwise, as he tore described, and the lower cams are simply dropped into place. in. their hearings, which is readily done, since the latter are in form semicireular. The lower hearings of each bracket are now brought to rest on the lower cams, and, finally, the link E is insertetl, \v'liich locks all parts in position, so that they cannot he displaced. Segnuimtal shoulders 11" and (1 are formed lwtween the twocam-hear ings (Z and d", Fig. 5, to take the hearing against'the table and the standard and to save finishing the entire face of the earns. 'lhe lever (1 and the arm I are attached to the cams in any suitable manner.

It will he seen that l anreiuthledby theuse of my improved structure to make the main part of my machine practically in three piecesnainely, the two tables and the standard dispensing entirely with all detachable bearings both on the standard and on the This adds great strength and rigidity to the machine, among other things enablin g me to plane off the tables or beds after the machine is set up, thus securing the most exact alignment. The use of the lever G gives me quick control over the table, and

d the clamp and segment render the nicest adj ustment possible.

It is evident that many changes and modifieations may be made in my machine, as here illustrated. and exactly described, without dc parting from the spirit of my invention as expressed in the claims.

The device here shown and described for raising and lowering the rear table, F, and that for raising and lowering the front table, F, are designed to he used in one machine, they being especially adapted to the requirements of each case.
