PORTABLE HAND PLANER.

Specification of Letters Patent.

Patented Mar. 11, 1919.

Application filed July as, me. Serial no. ceases.

To all-whom it may concern."

Be it known that 1, JAMES H. BLOODGOOD,

. ,a citizen of the United States, and a resi dent of Jacksonville, in the county of Duval and State of Florida, have invented certain new and useful" Improvements in Portable Hand-Planers, of which the following is a full, clear, and exact description.

The present invention relates to a portable hand tool, more particularly portable hand planers, to be used in smoothing exposed surfaces of wooden and other structures and also adapted, dependent upon the character of cutter, to performing the operationof roughing timbers, or to form a -furrow or channel, or to prepare the seams tion by means of which, and by a simple form of adjusting mechanism, the depthof out may be quickly regulated and adjusted.

A further object of the invention is to provide such a tool which can 'be quickly arranged so that the efi'ective operation of the cutters may take place on surfaces closely adjacent to other parts of the structure operated on, as in the angles between the deck floor and the upstanding sides of the ship.

4; further object of the inventionis to provide for the eflective lubrication of the operative parts and to permit the power driving connections to be changed from one side of the tool to the other, all as will be hereinafter set forth.

i To the above ends, the present invention consists of a hand planer comprising a body The invention is shown in the accompanying drawing is which:

Figure 1 shows a perspective view of the device.

Fig. 2 shows a longitudinal sectional view taken on a vertical line cutting the longitudinal center of the device.

Fig. 3 shows a transverse vertical sectional view taken on the line 3-3 in Fig. 2 looking in the direction of the arrow on such line. i

Fig. 4 shows a transverse sectional view taken on the line 4-4 in Fig. 2 looking in the direction of the arrow on line 4-4:.

Fig. 5 shows a side elevation of the tool with the forepart of the body portion removed so as to permit working close in angular corners.

Fig. *6 shows! one of the bushings of the shaft bearings removed.

Similar referencecharacters will be employed throughout the specification and drawings to designate the corresponding parts;

As shown in the drawings, the tool is equipped with a saw 1 which is angularly disposed on its shaft as shown in Figs- 3 and i, commonly known as a waibble saw, arranged to cut a groove 2 in the surface being treated. It is to be understood however, that in place of the wa'bble saw 1, may be substituted a planing cutter, a roughing ofi cutter, or'a plowing cutter, or any other desired tool, the operating face of which is arrangedto perform its work by a rotary motion.

' The. main frame or body portion comprises two sections, 3 and 48?, each of which consists of a face plate 5 and 6, provided along their opposite longitudinal edges with the vertical upstanding

parallel sides

7 and 8 respectively; the sides 7 being carried by the section 3, and the sides 8 by the section 42. The sides 7 at their forward upper ends are united by a cross plate or brace 9. The section 3 also carries a suitable r-i or handle 10 and the section 4 a suita 1e grip or handle 11. These sections 3 and a as so far described, may each of them be formed of a single casting of any suitable light, but

hers in any suitable or convenient manner. The section 1 1s removably connected to .the section 3, and for'this purpose the curedby means of screws 13 arranged to producedby the to be received in threaded openings 14 in the side walls 7 of the section 3.

In ordinary use the tool --is employed as shown in Fig. 1, but when it is desired to work close upon a surface closely adjacent to a-vertical surface, the forward section. 4 is detached, thus. producing the effect as shown in Fig. 5, which brings the cutting tool close to the forward end of the section 3. The upstanding walls of the sections provide a bcx-like frame, which is open from end to end longitudinally, and in this opening is arranged the tool carrier 15, which consists of an. "open frame having parallel side members 16 and a top member'17, all formed preferably of an integral casting of some suitable, but light and strong metal, andnear the lower edges and near the forward end the tool carrier 15 is provided with a crossbar 18 to brace the side wallsthereof. The tool carrier 15 is pivotally supported at its rear end upon a shaft 19 whereby it may have an .up and down movement for purposes which will be hereinafterdescribed. The tool carrier 15 is provided with suitable bearings 20 I which. are threaded" into seats or sockets 21 in the walls thereof, and in which is supported for rotary movement the tool carrying shaft 22 ,upon which is mounted the cutter, or

other tool 1, held fixedly theretoby any suitable means, as by means of the threaded nut 23, engaging a threaded portion 24: of the shaft 22 and the cooperating bushings 25 and splines 26. Any suitable means may be adopted for. rigidly ailixing the tool to the shaft; The side walls 7 of section 3 of the body portion are cut out upon segmental lines as shown at 27,

to permit the hearings or bushings to have freedom of movement therein and also to assist in permittin he escape of the waste c%. For this purposealso, a large clearance space 28 is provided in the body. portion to prevent clogging of the tool. Thepivotal action of the tool carrier 15 is intended to provide for the vertical adjustment of the cutting edge of the tool with relation to the-bottom or face plate of the body portion, so as to provide for regulating the depth of the cut, and; in the apparatus as shown there is a considerable latitude of vertical adjustment controlled and operated by a single adjusting device.-

This adjusting mechanism consists of a threaded screw 29 engaging a threaded aperture in the crossbar 9. At its lower which is pivctally connected a link 31, which at its lower end is connected to the cross-brace or bar 18. The arrangement is such that by turning the screw 29 the pivotal tool carrier 15 may be raised or lowered, about the shaft 19 as a center, thus raising or lowering the tool, and at the same time rigidly holding the tool in its adjusted position. The shaft 22 is driven from any suitable source or power by means of a flexible shaft 32 which is arranged to have a detachable connection, as by means of a screw thread 33, with the shaft 22. Of, course, this connection may be at either side of the device. As shown in the drawing, it is on the left hand side, but by removing the shaft 22 and transposing the bearings 20, the connection may be placed at theright hand side,

For the purposes of lubrication the side walls 7 immediately over the bearings for the shaft 22,-are provided-with oil-ducts 34: leading into the bearings for the shaft,

and oil-cups 35 provided with caps. 36

are mounted on the tool carrier immediately over the oil-ducts 3d.

Within the bearings 2'0 it provide tubular bushings 3? vvhich are cutout as shown at 38 to receive a 'packing-39. These bushings are made of light ductile metal and provide ed'ective means for retaining lubrication at the shaft 22.

It is to be noted that the top 17 of the points of bearing the tool carrier-is cut out or provided with a right angles thereto, to permit the tool to work close to the angle, and for this purpose the forepart of the tool is made removable, as has been explained.

It is thought that the operation of the device has been sufiiciently set forth in connection with the foregoing description of its construction and that further description of the operation thereof is unnecessary.
