2 Claims.

This invention relates to wood working machines, and particularly to machines known as sanding machines wherein a sanding wheel is supported on a rotating shaft, and against which the work is held during the sanding operation.

The primary object of the invention is to provide a machine .of this character including a motor operated shaft on which the sanding wheel is mounted, means being provided for adjusting Q 20 invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein described, may 25 be made within the scope of what is claimed,

without departing from the spirit of the in-' vention. Y Referring to the drawings:.

Figure l is a side elevational view of a sanding machine constructed in accordance with the invention.

Figure 2 is a front elevational view thereof.

Figure 3 is a view in elevation of the motor support.

Figure 4 is a-sectional view taken on line 4-4 of Figure 1.

, Figure 5 is a sectional view taken on line 5--5 of Figure 2.

Figure 6 is a fragmentalplan view of the machine, illustrating the stationary table'top.

Referring to the drawings in detail, the machine embodies a frame indicated generally by the reference character 5, the frame having a stationary table or top 5, which is formed with 45 a circular opening I that is of a diameter slightly greater than the diameter of the sanding wheel 8.

. This sanding wheel is mounted on the free end of the motor shaft indicated at 9, which shaft 1 extends from the motor ill, in the usual and well 50 known manner. An opening indicated by the erence character H extends from one edge of theitabie a, and terminates at the opening 1, so

thatIthe motor shaft 8 may swing therethrough,

when: the motor is from a vertical positioiafto a horizontal position.

The reference character I2 designates a. supporting shaft which is mounted on the frame of the machine 5, the shaft l2 being mounted in suitable bearings of the leg members of the frame. Mounted on one end of the shaft I2 is a pinion 5 [3 that meshes with the worm l4, mounted on one end of the shaft l5, there being provided a crank handle IE, on one'end of the shaft l5, whereby the shaft l5 may be rotated to rotate the shaft l2, for purposes to be hereinafter more fully dem scribed.

The motor support, includes a base plate I! that is formed with ribs l8 disposed along its longitudinal side edges. This base plate i1 is mounted on the shaft 12, through the medium of the bracket l9 that is bolted to the base plate ll, by means of the bolts 20. This bracket I8 is secured to the shaft l2, by means of the set screw 2|, with the result that the motor may be accurately positioned with respect to the shaft i2.

Plate 22 also forms a part of the motor support, and is provided with beveled side edges, fitted under the ribs i8.

One end. of the base plate I! extends at right angles, "where it is provided with an opening through which the threaded shaft 23 extends,

, 't'he shaft 23 also extending through a threaded opening in the plate 22, as clearly shown by'Figure 5 of the drawings. On one end of the shaft 23 is a crank handle 24 whereby the shaft 23 may be readily rotated to move the plate 22 of the motor support, longitudinally of the base plate H, to adjust the motor with respect to its support.

The reference character 25 designates the bench or work rest forming apart of the machine, and as shown,this bench or work rest 25 includes a bracket 26 that extends downwardly and is provided with an extensionfl formed with a threaded opening, through which the threaded o shaft 28 extends. This shaft 28 is supported in the lug 29 extending from the frame of the machine, the shaft 28 being provided with a handwheel 30, whereby the shaft 28 may be rotated.

It is obvious that when the shaft 28 is rotated, the bench or work support 25 will be moved vertically,= so-*that the work may be supported on the bench 25 in an adjusted position,.with respect to the sand wheel.

A set screw indicated by the reference char- 5o acter 31 extends through the extension 21, and is adapted to engage the shaft 28, securing the' bench or work support 25, in its adjusted positions.

As clearly shown by Figure 2 of the drawings,

the bracket 26 of the bench or work support 25, moves under the flange plates 32 that are secured to the frame of the machine, the plates 32 acting as guides for the bracket 26 of the bench or work support 25.

From the foregoing it will be understood that due to the construction shown and described, the sanding wheel may be readily and easily moved from a vertical position as shown by Figure 1 of the drawings, to a horizontal position, wherein the shaft 9 operates in parallel relation with the bench or work support 25, adapting the device for use in sanding articles wherein it is necessary to support the articles at various angles with respect to the sanding wheel.

I claim:

*1. In a sanding machine, a frame, including a table having an opening extending inwardly from one edge thereof, a motor support including a base plate having flanges formed along the edges thereof, said flanges forming guides, a slide slidably mounted on the base plate, the side edges of the slide moving under the flanges, said slide having a threaded bore, athreadedshaft supported on the base plate and movable in the threaded bore, a motor mounted on the slide, a shaft driven by the motor and adapted toswlng through the opening, a grinding wheel on the shaft, said threaded shaft adapted to be rotated for adjusting the motor and shaft with respect to the table, and means for swinging the motor and motor shaft from a vertical position to a horizontal position.

2. In a sanding machine, a frame, a table forming a part of the frame and having an elongated opening extending to one edge thereof, a vertically adjustable pivoted support'mounted on the frame, a motor mounted on the support and adapted to swing laterally with respect to the table, a shaft extending through the table and adapted to move laterally through the elongated opening to assume a horizontal position, a sand-' ing wheel on thefree end of the shaft, and means for swinging the motor laterally whereby the sanding wheel may be operated in various positions from a vertical to a horizontal plane.
