manna.
Application filed September 4, 1920. Serial No. 408,300.
the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to reamers shown in the accompanying drawings and more particularly described in the following specification and claims.
One of the objects of my invention is-to construct a reaming tool having radial blades, of relatively few parts, adapted for a minute longitudinal and radial adjustment, whereby they may be expanded to adapt the tool for the work and to compensate for wear, and the grinding of the blades when sharpened.
A further object of the invention consists in the means for quickly and rigidly securing the blades when adjusted, so that no looseness of action or chattering of the blades will occur while at work.
With the foregoing and other objects in view which will appear as the description proceeds the invention further resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes may be made in the precise embodiment of the invention herein disclosed without departing from the spirit of the same.
In the accompanying drawings Figural is a longitudinal sectional view of the reaming tool.
Figure 2 is an elevation with parts in section.
Figure 3 is an elevation showing a modification in which the blades are disposed in inclined longitudinally arranged grooves.
Figure 4 is a fragmentary cross sectional view showing the manner in which the inclined or cutter blades shown in Figure 3 are held in position by the set screws.
Figure 5, is an elevation of one of the cutter blades.
Referring now to the letters of reference placed upon the drawings A, denotes the body ot the tool. B, 1nd cates a plurality of peripheral grooves in the body of the tool, which may be disposed parallel with its longitudinal axis, or may be inclined at an angle thereto, as indicated in Figure 3;the bottom of the grooves being inclined outwardly toward the front or forward end of the body portion.
C, indicates a series of removable blades respectively lodged in the grooves B, of the body portion.
E, are set screws, screwed into the body portion A of the tool, having projecting heads E lodged in the longitudinal grooves D, formed in the sides of the cutter blades the head of the set screws being chamfered as indicated at e, on their underside to bear agalnst the bevelled edge (1, of the longitudinal grooves D, of the cutter blades, in order that upon the adjustment of the screws the blades may be .forced snugly agai the side and bottom walls of the groove in which they are lodged.
When the cutter blades E are arranged parallel with the longitudinal axis of the tool,(as shown in Figures 1 and 2) the set screws E are lod ed in holes tapped in the body of the tool in a line tangent to anarc concentric with its central bore, as shown in the latter view.
When the cutter blades are lodged in grooves formed at an angle to its lon 'tudinal axis, (as shown in Figure 3), t e'set screws enter holes tapped at an angle or radially into the body of the tool in order to provide full body stock surrounding-the head of the set screw, as shown in Fi are 4.
To overcome the stress caused by t e lateral thrust of the cutter blades against the heads of the set screws E, the tapped holes in the body are counterbored to receive the heads of the screw, the surrounding wall of the body portion thus serving to support the head of the set screws against the lateral thrust of the cutter blades.
F, indicates an adjustable collar screwed upon the body portion A having an inclined end wall adapted to overlap the inclined ends C of the several cutter blades.
G, denotes a set screw carried by the adjustable collar=having a projecting end G adapted to enter the longitudinal grooves D in the body portion, to secure the collar when adjusted.
Having now indicated the several parts by reference letters the construction and operation of the device will be readily nnder stood.

lit)
When it is desired to take up wear or to again turned to secure the collar against accidental release, which together with the several set screws E, serves to. secure the blades in their respective slots.
Having thus described my invention what I claim is 1. In a reamer, a body portion having a plurality of grooves to receive a series of cutter blades, a plurality of removable cutter blades fitted to said grooves each having an inner slanting end, a thrust collar screwed upon the body portion and having an inclined face adapted to impinge upon the slanting ends of the said cutter blades, and
a set screw carried by the collar and having memes ter blade, at set screw having a smooth re-' duccd portion carried by the said collar and projecting into the extended portion of the groove, the said reduced portion having a flat lower face contacting with the inclined base of the groove at its edge and adapted to bite intothe said inclined face whereby chattering is eliminated.
In testimony whereof, I sign this specification in the presence of two witnesses.
JAMES J. CONNELL.
