To d/Zwhom zt 11mg concern.-

Be it known thatI, ERNEST K. MoCoY, a citizen of the United States, residing at Portsmouth,in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Sanding-Tools g and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in rasplng and sanding tools, and more particularly to a device of this character which may l portable power-drill or similar too The object of the invention is to provide a device or attachment of this character which will be simple in construction, durable and efficient in operation, and comparatively inex ensive to manufacture.

. ith the above and other objects in view the invention consists of certain novel fea-' tures of construction, combination, and arrangement of arts, as 'will be hereinafter more fully described, and particularlypointed out in the appendedclaims.

In the accompanym drawings, Figure 1 is I a longitudinal sectiona view through my improved sanding-tool, showing the same a plied toa portable pneumatic or` power dri l. ig. 2 is an end elevation of the same. Fig. 3 is a vertical transverse sectional view taken on the plane indicated by the line a a of Fig. 1.- Fig. 4 is a detail view showing the manner in which the cylindrical body of the at- 'tachmentlmay be adjusted to clamp the sanding or rasping face thereon. Fig. 5 is a erspectiveyiew'of the rasping-cylinder W 'ch may be substituted for the sanding-cylinder shown in Figs. 1, 2, and 3, ard Fig. 6 is a longitudinal sectional view through aslightlymodified form of the invention.

My improved rasping and sandin tool 1 is in the form of an attachment whic may be secured upon a power-drill D of the usual form and construction or upon any other suitable portable tool having a rotatable spindle F. As shown in the drawin s, the tool D is'in the form of a neumatic dril of usual con-` struction, the bo y portion of which is cylindrical, as at C, and formed at one end with the usual removable cap and a handle H, the rotary spindle F being at its opposite end and having a socketf to receive a drill or the hke.

The device or attachment 1 comprises a substantially cylindrical body portion 2, which is formed, preferably, of sheet metal and is divided longitudinally, as at 4, to Y erniit its edges to be adjusted toward and from each other to vary the diameter of the body. This adjustment is preferably eected, as shown in Fig. 4, by providing projecting lugs 5 adj acent to the edges 4 of the body 2 and by providing a set-screw 6,which extends through a threaded opening in one of said lugs and has its inner end enga ed with the other. lugs 5.are removab mounted in brackets 7, which are secured adj acent to the edges ofthe body 2, so that-when the screw 6 is turned in the roper direction the body 2 will be eX- pan ed to clamp a sandin or ras ing surface upon its outer face. T e sensing-face is clearly shown in the first two figures of the drawings and consists of a'cylinder 8 of felt or other suitable cushioning material, which is covered with sand cloth, pa er, or the like 9. When lthe attachment is to e used for rasping urposes, a cylinder 1() (shown infFig. 5 j is su stltuted for the sanding-cylinder. The cylinder 10 is of metal and has its outer face roughened, as shown at' 11, or in any other suitable manner, so that it may be used as a rasp. It will be understood that the adjustment of the edges 4 of the body2 is very slight, so that the working face of the tool 1s at all times cylindrical. The body2 is secured at suitable points by means of screws or the like 12 two removable heads 13 14. The latter are open or in the form of spiders, each The a stub-shaft 18, which has mounted upon it a handle 20, and on the inner face of said hub is an inwardl -pro'ecting shank 21, adapted to be secure v1n t e socket f of the rotary drill-spindle F.

In Fig. 6 I show a modified construction in. which heads are' formed integrally with the c linder. When this is done, the shank 21 is the only point of connection of the attachment to the drill, the inner end ofthe attachment being o en to ermit of ready access to an part of t e dril D, as will be seen.

he construction, use, and, advantages of IOO the invention will be readily understood from the foregoing description, taken in connection with the accompanying drawings. It will be seen that the device or attachment may bereadily applied to any styleof portable power-drill and that it may be used in various ways. By grasping the handles and H the rotating body portion of the attachment with its sanding or rasping face may be readily moved over the surface to be operated upon.

Various changes in the form, proportion, and the minor details of construction may be resorted to without 'departing from the principle or sacrificing any of the advantages of the invention.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-d 1. A rasping and sanding tool comprising a longitudinally-slit cylinder, an abrasive cylinder on the slit cylinder, brackets 7 on the inner side of the slit cylinder, at the ends thereof and on opposite sides ofthe slit therein, lugs 5 in the said brackets. and projecting beyond the ends of the slit cylinder, and setscrews connecting the Vsaid lugs, substantially as described.

2. A rasping and sanding tool for use in connection with a rotary power hand-drill, and comprising a cylinder having a longitudinal split on one side7 an abrasive cylinder on the split cylinder, means to diametrically expand and contract the split cylinder, and removable heads in said split cylinder, one of said heads having a central opening to form the bearing for the cylindrical portion of the power-drill and the other having a bearing for the shank of a handle for attachment to the drill-spindle.

In testimony whereof 1 have hereunto set my hand in presence of two subscribing witnesses.

ERNEST K. McCOY.
