UNITED STATES PATENT OFFICE.
H. C. INGRAHAM, OF GUILFORD, AND H. S. INGRAHAM, OF GRANGER, OHIO.
ROTARY PLANING-MACHINE.
Specification of Letters Patent No. 23,250, dated March 15, 1859.
To all whom it may concern:
Be it known that we, H. O. INGRAr-IAM, of Guilford, in the county of Medina and State of Ohio, and H. S. INGRAHAM, of Granger, in the county of Medina, Ohio, have invented new and useful Improvements in Planing-Machines; and we do hereby declare that the following is a full and complete description of the construction and operation of the same, reference being had to the accompanying drawings, making part of this specification.
The nature of our invention consists in such an arrangement of devices that by turning a single screw, the upper feed rollers, the knife cylinder and the match burs, can all be elevated at once, the feed gears being so arranged as to adjust themselves to this change of position, in relation to the driving wheel, the match burs being elevated at the same time and to the same extent, a uniform thickness of timber is secured between the face of the board and the groove and tongue, in all cases where matched lumber is wrought, independent of any variation in the thickness of the board itself; also, in the construction and arrangement of devices by means of which the edges of the boards are matched straight and parallel with each other.
Figure l, in the accompanying drawings, represents a side elevation of the machine, as viewed upon the right side, loo-king forward. Fig. 2, is a top view. Fig. 3, is an end view, looking forward. Fig. 4, is an end view looking backward. Fig. 5, is a section.
Like letters refer to like parts.
A, inthe several figures, represents the frame of the machine. This may be made of iron. Wood may be used, but we much prefer iron.
B, in Figs. 2, 3 and 4, represents the bed vplate upon which the boa-rds to be planed,
are placed.
C, represents the main pulley of the driving wheel, which receives the belt D, from the engine, or motive power.
E, represents a pulley placed upon the opposite end of the shaft, that carries the pulley O, and E', the belt that carries the cutting cylinder F, Figs. 2, 3 and 4.-, the pulley of which is seen at F' Figs. 3 and 4, its position being also indicated at F', in Fig. 2. The cutting blades which act upon the face of the board` are secured to the cylinder F, by screw bolts in the usual manner.v
G, in Figs. 2 and 3, represents the upper roller in the first pair of feed rollers, and G', in Figs. l and 3, represents the journal of the lower feed roller, first pair. The upper surface of the feed roller G', is just on a level with the upper surface of the bed B, and the boxes for its journals being attached to the main frame A. This roller remains stationary at this point.
H, represents the upper feed roller of the second series. This and its fellow, H', which lies directly below it, receives the board after it has been planed and matched, and delivers it from the machine. The roller H', like the roller G', is attached in a stationary manner, to the frame A, by means of journal boxes. Both the upper feed rollers G and H are secured to the vertical sliding frame I, by means of journal boxes, having an elastic packing above them as Seen at J, for the purpose of accommodating different thicknesses and inequalities in the boards.
The feed rollers are put in motion by means of the cog wheels K and L, the pinion upon the end of the roller H forming the connection between the cog wheels K and L The cog wheel K, receives its motion from the pinion M, upon the end of the conical drum shaft N, which is driven by a belt from the drum O, which in turn is driven by the belt O from a small pulley upon the main shaft, upon which is placed the pulleys C and E. The belt which passes over and around this pulley is seen at O Figs. 1 and 3.
The pinion wheels of the rollers G and H, are moved by intermediate pinions I), Q, which have their bearings respectively in the arms P', Q', seen in section Fig. A5. These arms extend obliquely upward, from the center of motion `of the cog wheel L; to the respective ends of which are attached by journals, the pinions I), Q. Now, in raising and lowering the frame I, which carries with it the rollers G, H, and their pinions, the intermediate pinions P, Q, are kept sin gear with the cog wheel L, by the arms P', Q', and also in gear with the pinions upon the ends of the rollers G, H, by the curved slots R, R', Fig. 5, which are concentric with the pinions upon the shafts G, H. In this manner, the frame I, with its dependent parts, can be raised and lowered at pleasure without at all interfering with the action of the gears.
The sliding frame I, carries in addition to the cylinder F and rollers G, H, the
matching burs S, S. These are caused to revolve in the direction of the arrows, by means of the belts from a horizontal drum upon the driving shaft, to pulleys upon the vertical shafts that carry the burs S, S. The steps and boxes which support the bur shafts, are attached to the sliding frame I, and rise and fall with it, consequently, the matching burs S, S, cutting cylinder F, and upper feed rollers G, H, always occupy the same relative position. The shaft of the bur S is adjustable laterally, by means of the screw T, to which the boxes of the shaft are attached. In this manner we can accommodate it to any width of board.
The frame I, is raised by means of four inclined planes, two of which are seen at U U, Figs. l and 5, the other two being upon the opposite side of the machine, are not seen in the figures. The inclined planes are moved by a screw, the head of which is seen at U Fig. 4. By turning this screw to the right, or forward, the frame I is raised, and by turning it backwardv the frame I is lowered, and with it all 'its dependent attachments, consisting of both the upper feed rollers, the cutting cylinder and the matching burs.
For the purpose of keeping the board firm and steady, while passing under the first feed roller, and onward till it reaches the second pair of feed rollers, and also for causing the board to be cut straight and parallel upon its edges, while passing between the matching burs, we provide a sliding grip V, Figs. l and 2. This grip consists of a crosshead, which runs upon ways W, W, seen in Fig. 2, and a cam lever X, which is held in place by the ratchet X, when brought down in contact with the board and secured in one of the notches in the ratchet or catch X. The lever X has a spring beneath it, which throws it back as soon as it is released, and this is accomplished by means of a guard Y, which releases the vlever from the catch by coming in contact therewith, as the board moves forward.
The grip V, is drawn back as soon as released from the board, by a weight Z. An adjustable guide a is placed upon the frame of the machine as seen in Figs. 1 and 2. This consists of a long arm which articulates upon thejpin Z) Fig. 2. The forward end of this arm is bent at right angles as seen at c, Figs. 1 and 2, against the end of which the edge of the forward end of the board is brought in contact, when it is placed in the machine. The other end is adjusted to a shoulder in the grip V and secured by the lever X.
An adjustable stop d, Figs. 1, and 2, is placed upon the back end of the adjustable guide, which stops the grip in its backward movement, and is set to accommodate any length of board. The forward end of this adjustable stop, is wedge shaped upon vthe inner surface, so that the grip in its backward movement carries the back end of the arm outward. This brings the inner end of the angle c, upon a line parallel with the shoulder in the grip V. The object of this arrangement is to give the angle c, a movement outward as the board is carried through the machine.
What we claim as our invention, and desire to secure by Letters Patent, is-
1. The arrangement of the cylinder F, with the two upper feed rollers and the matching burs, in combination with the vertical sliding frame I, for the purpose of preserving the same thickness of timber between the face of the board, and the tongue and groove, as set forth.
2. IVe further claim the sliding grip V, in combination with the ways IV V, lever X, and ratchet X, all arranged and operating in the manner and for the purpose set forth.
