GEORGE A. DICKIE, OF RAYMOND, WASHINGTON.

PLANER FOB. THE SURFACES 0F SHIPS.

To all whom t may concern:

Be it known that I, GEORGE A. DIGKIE, a citizen of the United States, and resident of Raymond7 Pacific county, Washington, have invented certain new and useful Improvements in Planers for the Surfaces of Ships, of which the following is a specification.

My invention relates to apparatus for use in smoothing and dubbing off the outer surfaces of wooden ships and other like surfaces of large area, and comprises a planer head and the means for mounting and operating it so as to cause it to progressively travel over the surface of the ship and dress it down to a smooth evenly rounded surface.

The object of my invention is to provide mechanical means for doing this work, of such a design that it will automatically accommodate itself to many variations of conditions which will be found in doing the work and which shall be capable of covering a large area in a small time.

The features of my invention which are new and upon which I desire to obtain patent will be described in the following specification and then specifically pointed out in the claims.

In the accompanying drawings I have shown my invention as embodied in an apparatus designed for doing a specific work and under specific conditions. It will, however, suiice to illustrate the principles of my invention and a preferred manner of carrying it out under these conditions.

- Figure l is a cross-sectional view of a side of a ship showing my device applied for the planing of its outer side surface.

Fig. 2 is a like gure showing its ap plication to planing the bottom of a ship.

Specification of Letters Patent. Patented Feb. 18, 1919. Application filed February 27, 1918. Serial No. 219,375. i

Fig. 7 is a cross section of the outer end of the cantaliver frame or carriage, showing the pivotal attachment of the guiding bar or post thereto.

Fig. 8 is a side view of the bearing or guide shoe and the relation of said shoe and the cutter head with the surface of the ship when in use.

Fig. 9 shows the manner of using a hatten secured to the ship when starting the work upon a ship.

Fig. 10 illustrates the manner of compensating for curvature of the surface of the ship by adjustment of one of the shoes.

In wood ship building, after the planking has been put in place, it is customary to plane over the outer surface so as to secure a smooth, true and regular surface. Without doing this the surface would be irregular because of imperfect matching as to thickness along the meeting edges of planks; also because of the outer surfaces of the planks being planes where, in many places, the outer surface of the ship should be true and regular curves. Y

By my invention I provide a cutter head, mounted in a frame and in conjunction with a pair of shoes, one of which is alongside the cutter head, and means for moving this over the surface of the ship to smooth down its inequalities. The cutter head is carried by a pivoted frame which is counter weighted to hold the cutter head up to its work and this frame is moved along a guide which extends along but a short distance from the surface to be planed.

The cutter head 1, may be of any type which proves suitable for the work. The type which I now use is essentially the same as is used upon a tenoning machine. vUsing such a head the shaft 10 would be parallel with the surface of the ship.

The shaft is journaled in one end of a frame 16 which is pivoted upon trunnions 17.

to form a horizontal axis. These trunnions are secured to a sleeve 18 which is mounted to slide and turn freely upona guide bar 2.

The frame 16 is supported and moved alongthe guide bar 2 in any suitable manner, as by a small wire cable 20.

The frame 16 is thus supported `as if float` ing, being free to swing about botlr a horizontal and a vertical axis. lts position is determined by engagement of shoes 3 can ried by the inner end of the frame and pivoted thereon concentric with the axis of the cutter head and its shaft.

The shoes 3 are of a compound construction, consisting of a base 30 and a. removable face bar 31. The shoe has a pivot eye 3l. The face bar 31 should be of a thickness corresponding with the thickness of the batten Which I use when starting the Work of planing a ships surface. At this time the bar 31 is removed.

This bar should preferably be secured so that the distance of its contact face from its pivot axis may be adjusted to conform to theradius of the cutter head. A convenientway todo this is to use securing bolts 32 and adjusting bolts 33.

The cutter head may be driven in any manner found suitable. l have shown it as driveny from an air motor 15 carried by the opposite end of the frame 16 through a belt 12 anda pinion 11 secured on shaft 10. I alsolsupply a fly Wheel 141 to assist in maintaining rotationy when the cutter strikes a. treenail or other spot which is hard to plane.

The cutter head 1 may be placed on either end of the' shaft 10, but I do not contemplate ordinarily using a cutter head on each end, although' this might be done if desired. 1 do, however, contemplate using tivo guide shoes 3, these being placed just inside the positions occupied by the cutter heads. As the' frame 16 isfree to move about a vertical pivot, thel post 2, and has two bearings against the surface of the ship, thus giving a three point support, it will adjust itself to conform to change in outline of the ship.

The post 2 is made of pipe sections joined together in such manner as to leave a smooth outer surface. lts length may thus be adjusted to suit diderent situations. At its lower end it should be provided with means for securing it in position. I have shown dogs 21 carried'by guides 22. These dogs maybe driven into scaffolding planks or the ground, as is necessary.

To support the* upper end of the post 2 and to provide means for adjusting the post and the frame 16valong the ship, T employ a mechanisml which isshovvn in side elevation in Fig. land in plan in Fig.' 4.

Supported in horizontal position above and extending lengthwiseV the rail 29 is a threaded bar 4s The ends of this are journaled in' strands or brackets -lO Which bear upon the railand are secured thereto, as by clamping boltsv L11. These, as illustrated, have' offset-0r yhooked ends e3 which engage with the underside of the rail.

A cantaliver or carriag'e'frame 5 has bearing'lfugs or bosses, 50, which are threaded to receive the bare and the bar et has a. hand Wheel 42, or other suitable means whereby it may be turned, to thereby cause a bodily movement lof the frame 5 along the rail` The bar 4 also forms a. pivot upon which the frame may rock.

The outer end of this frame has tivo side bars 51 adapted to act as guide rails for a carriage or sliding block 6. This block has standards 63 in which is ournaled the shaft of a sheave 62 over which passes the rope 2O which sustains the frame 16 and the planing mechanism. This rope passes to a drum 57 carried by the other endv of the frame 5. This drum has a brake 53 and preferably is driven through a vvorm gear 52 and Worm 59, the latter being on shaft 54; which is connected through bevel gears 55, 56, with the sli aft 57 of an air or electric motor 58.

The slide block or carriage 6, has ears 60 threaded to receive threaded shafts 61 which have beveled gears 65 meshing with like gears 66 carried by a transversely place-d shaft 67, which is turnable by a hand Wheel 68 to thereby cause the slide block 6 to move along the cantaliver frame 5 and thus adjust the position thereof relative to the side of the ship. The slide 6 has depending ears 69 in Which, by a horizontal pin 24, is pivoted the head 23 with which post 2 is secured.

At the inner end of the frame 5 I provide means for supporting it, the same consisting of tivo threaded rshafts 7 which engage threaded sockets 7 5 of' a yoke 73 which is secured by horizontal pivots 74 from the end of the frame 5.

The lower ends of shafts 7 are rotatively fixed in a frame 7 O which may be provided with supporting Wheels 76. Bevel gears 71 connect the shafts 7 with a transverse shaft 73 upon which is a hand Wheel 7 2. By these means the effective length of the posts formed by shafts 7 may be adjusted.

Tn using my machine, the cantaliver frame 5 is mounted on they rail of the ship and the guide bar 2 made of the right length by adding or removing sections. The support for the inner ends of the frame 5, namely the rods 7, arel adjusted so that the Wheels 7 6 Will bear upon the deck planks. This inner end of the frame is provided'vvith counteriveights 8 which may be used orv not as desired, and which support the outer end of the frame 5. i l

The carriage or block 6 may be moved outward or inward, as desired, to; adjust the positionof the guide lbar 2, relative tothe side of the ship. The lower end of bar V2 is secured by driving the` spikes 2O into the boards of a scaifolding of a dock or into the ground.

ln starting the `Wear plate 3l of the shoe is removed; To'thej surface of the ship is secured a batten or guidev strip, 9, see Figs. 3 and 9, extending vertically. This should be of a thickness corresponding with the thickness of the shoe 31. This batten is used as a guide for the shoe 3. Its outer surface is a smooth, regular curve and therefore, the surface cut by the cutter head will be a like curve. This dresses down the edges of the planks on the curves, more than their centers, and dresses down the thick planks more than the thin ones. After a smooth surface has thus been formed on the ship, the plate 3l is replaced and the guide strip or batten 9 is not used.

Vhen one vertical cut has been made, the device is moved along an amount equal to the width of the cut. This is done by turning the shaft 4. The dogs or spikes 21 are withdrawn so that the bar 2 may move. The weight 0f this bar is normally suspended from the cantaliver frame 5.

When it is desired to plane the bottom of the ship the apparatus will be set up as shown in Fig. 2, with the guide bar 2 extending to the bottom of the ship. In this case the standards which carry the bar 4L would be supported on a. scaffold or trestle.
