IMPROVEMENT IN PLANlNG-MACHINES.

Specification forming partof Letters Patent N 0. 120,448, dated October 31, 1871.

To all whom it may concern:

Be it known that we, CHARLES E. MoBETH, FREDERICK BENTEL, and WILLIAM G. MARGE- DANT, of Hamilton, in the county of Butler and State of Ohio, and HENRY CLIMER, of Muscatine, in the county of Muscatine and State of Iowa, have invented a new and Improved Universal VVood-Working Machine; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable oth ers skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification.

This invention relates to improvements in the universal wood-working machine for which Letters Patent of the United States, dated November 27, 1866, and numbered 59,966, were granted to Henry Climer and John D. Riley. The present invention "consists chiefly in a new arrangement of adjustable tables, whereby certain advantages are secured in Wood-working, as hereinafter described.

A in the drawing represents the supportingframe of the machine, made of cast-iron, wood, or other suitable material, of such proper size, form, and strength as to sustain the several appendages, shafts, &c., which constitute the working mechanism. B is the driving-shaft of the machine. It is horizontally hung in the frame A, and receives rotary motion by suitable means, transmitting it by gear-wheels a a I) b to the feedrollers on the molding attachment or sticker, and by belt or otherwise to the mandrel (J hung transversely in the upper part of the-machine. D is the verticallyadjustable back-table of the ma chine. It rests upon wedge-shaped projections d (I of a longitudinallyanovable carriage, E, that can be moved by means of a screw, 0. The table I) has no horizontal motion whatever, neither latterally nor lengthwise, but is only verticallyadj ustable in the manner stated. In front of the back table D are the adjustable front tables F and F. These consist of the table-topsfj" and tableframes 1 g. g g, and are connected with them by bolts and nuts h. A spring-pawl, 17, projects from each table-firame into a toothed portion, j, on the under side of each table-top, and arrests the latter in any position, preventing it from sliding toward the cutter, permitting, however, when drawn out of the rack, longitudinal adjustment of the top on the frame. Each table-frame g g rests upon wed gosh aped projections K K of a longitudinallyadjustable carriage, G, which can be set by means of a screw, 1. By moving the carriage lengthwise the tables with their frames are adjusted vertically. From. the inner end of each table-frame g g projects an inclined rod, 921, into and through a tube, a, pivoted to the frame A. lVhenever the screws I are turned to elevate the tables F F the angle-irons n2, sliding in the swinging tubes in, will cause an advancing movement of the ta bles toward the rotary on themandrel C. It will be seen that the mandrel, carrying a suitable cutter, H, is hung in the frame A so as to be about midway between the tables F F. These tables can be set at thesame height to serve as an ordinary planing-table, or at different heights for planing out of wind, pointing, or squaring. For planing out of wind the front table or bed behind the knives shonldbe adjusted to the height of the circle described by the knives when revolving. knives is then lowered according to the thickness of out desired. These adjustments can be made in a moment, while the machine is in motion. The stuff is passed over the knives, and after having reached the bed behind the knives has a solid bearing, an d will consequently be placed perfectly out of wind and smooth. A fence, I, is placed upon the back table I), and serves as a guide for the stuff to rest against at a suitable angle while passing over the knives. After the stuff has been placed out of wind on one side it can be jointed or squared by turning the planed side next to The tops ff rest upon the frames The other bed or front table in front of the shown in Figs. 6 and 7.

the fence and passing overthe knives as before. For tapering, the front table in front of the cutter should be lowered according to the taper required, the stuff resting on both front tables before commencing to plane. The fence I is, by pivoted arms 0 0, connected with slides J J fitted upon the back table D, said slides being slotted to be laterally adjustable on the back table. Slotted rods p p, projecting from the back of the fence and resting in horizontal grooves of the slides J, serve as braces for holding the fence in any suitable inclined position, and are locked by thumbnuts 7" to secure the fence vertically or inclined. The stuff is leaned against the inclined fence whenever beveling is to be done. In Figs. 8 and 9 is shown the adjustable gainer-frame L, and by dotted lines in Fig. 2 its application to the front tables. It consists of a sliding-board, s, placed in the recess of the front table-top, and has pivoted to it a guide-rest, t, that carries a sliding end-rest, u. The guide-rest has a slotted are, c, which is, by a screw,- w, clamped to the board 8 in any suitable position to set the guiderest obliquely, as required. In arranging for gaining, a proper gaining-head is placed on the mandrel, and the back table D lowered or raised to leave as much head above it as depth of gain required. The gaining-frame, which is quickly adjustable for any angle, is with the slide-board placed into the recesses of one front table, the guide-rest t lying level on front and back tables, as indicated in Fig. 2, the front tables having been adjusted as to height accordingly. The stuff is placed in front of the guide-rest and then moved along with the gaining-frame. Gains can be made straight at an angle part way through,

and of any desired shape and size. For plowing, the fence is used as a guide, and two or three heads can be used at the same time, which will work equally well for gaining or plowing. M is the adjustable saw-board. It is, when used, placed upon the ends of the front frames g g and under the noses of the front table-tops ff, as is clearly It requires no other fastening. A saw, N, mounted upon the mandrel 0, projects through a slot of the saw-board M,

two or more saws being used, if desired. The

board M, it will be seen, is flush with the front tables F F, so that thus a superior bed for sawing is obtained. The fence I may be used when ripping, and removed for cross-cuttin g, in which latter case the bed D is brought flush with the tables F F. 0 represents a sticker or additional table affixed to the back of the frame A to constitute a molding attachment. The mandrel 0 is elongated to extend partly over the table 0, as shown, and carries a head, P, above the same for planing, if desired, on two or more sides at once. It R are the feed-rollers for this molding attachment. They are hung in a removable cap, S, which is by a pin, X, fastened to the frame A, and carry pinions y y, gearing by the wheels I) a, into the driving-shaft B, as is clearly shown in Figs. 10 and 11. The bed 0 can be made vertically adjustable under the feed-rollers R for planing or molding thicker or thinner stuff. The molding-head T is mounted upon a shaft, U, which is hung to a downward extension of the sticker, and can be adjusted laterally and swung to a suitable angle. V'represents the rabbetingiron. It is provided with projecting pins 2 z, which enter apertures in the ends of the tabletops f f, and is also held in place by the noses of these tops, as shown in Figs. 1 and 2. It serves thus to bridge both front tables, and gives room for the rotary cutter. The rabbeting-cutter, shown also in Figs. 1 and 2, has spur-knives a a near its end, which pass close to the rabbetingiron, so as not to tear or splinter the material when tenonin g and rabbeting.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. The arrangement of the spring-pawls with racks 'ij, table-topsfj", and frames 9 g, as specified.

2. The front table-tops f f placed upon the front frames 1 g, and. locked thereto by the springpawls and racks z'j, as set forth.

3. The longitudinally-adjustable carriages G, carrying the inclines K K, and combined with the front tables F F, rods m and pivoted tubes n,-all arranged to operate substantially as herein shown and described.

4. The gainer-frame L, provided with the guiderest t and end-rest u, substantially as herein shown and described.

5. The adjustable saw-board M, slotted as described, and combined with the front frames g g and table-tops ff, in the manner specified.
