BEAMER. i
Application filed May 11,
This invention relates to improvements in reamers and has for an object the provision of a tool of this character wherein the cutters may be adjusted to regulate the diameter of an opening, novel means being provided wherein this adjustment may be accurately and expeditiously effected.
With the aboveand other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully'described, illustrated in the accompanying drawings and pointed out in the appended claim.
In the drawings Figure 1 is an elevation of a roaming tool constructed in accordance with the invention.
Figure 2 is a central longitudinal sectional view of the same.
Figure 3 is a transverse section through the mandrel and the cutters.
Figure 4 is a similar view through the opposite end of the tool and showing the manner of holding the cutter retaining means in place.
Figure 5 is an enlarged longitudinal sectional view through the mandrel end of the tool and illustrating by dotted lines the manner of adjusting the cutters.
Referring in detail to the drawings, wherein like characters of reference denote corresponding parts, the form of the invention shown in Figures 1 to 5 inclusive includes a shank 15 and a mandrel 16 which may be detachably secured together and may have an interlocking connection which includes diametrically oppositek lugs 17 which extend from the shank and engage notches or recesses 18 provided in the adjacent end of the mandrel 16. The shank and mandrel are hollow and the outer end of the mandrel is provided with a head 19 having longitudinally disposed spaced grooves 29 therein. These grooves are adapted to removably receive cutters 21. These cutters as illustrated include beveled shoulders 22 and relatively narrow outer ends 23. The beveled shoulders 22 are adapted for engagement by a head 24 positioned within a relatively large bore provided in the outer extremity of the mandrel head 19.
The head 24 at one end of a rod 26 extends upward through the mandrel and shank. This head 24 may be rigid with the rod 26, or may consist of a disk 27 rigid with the rod and a ring 28 mounted upon the disk.
1923. Serial No. 638,359.
This ring is provided with an annular seat for the reception of the disk 27 and the opposite edge of the ring is beveled as at 30 for engagement with the beveled shoulders 22 of the cutters 21. f
The inner end of the rod 26 is provided with a transversely arranged elongated slot 31 which is adapted to be brought into register with a relatively long slot 32 provided in .the shank 15, the slots 31 and`32being adapted toy receive a flat pin 33 whose.
opposite ends extend beyond the periphery of the shank. The ends of the pin 33 are engaged by a flange 34 which is carried at one end of a sleeve 35, the latter having a threaded en agement as at 36 with the shank 15, so that y screwing the sleeve upon the shank, the rod 26 may be drawn inward so that the beveled edge of the ring 28 will engage the beveled shoulders 22 of the cutters 21 and draw the latter inward.
Threaded upon the inner end of the mandrel 16 is a sleeve 37 which is provided at one end with an inwardly extending beveled edge 38. The edge 38 is adapted to engage the beveled ends 39 of the cutters 21 so that the latter will be securely held in place. Also by adjusting the sleeve 35 and the sleeve 37, the outer ends lof the cutters 21 may be moved diametrically outwardso as to engage the diameter of the cut. To facilitate operation of the sleeves 35 and 37, the
latter are preferably ymilled or knurled upon the outer peripheries, while the last mentioned sleeve may have extending therefrom a milled pin 40. y
The sleeve 37 has its inner end beveled and graduated as at 41, these graduations being adjusted relatively to the point 0 upon the mandrel as indicated at 42 so as to regulate the diametricaladjustment of the cutters.
The cutters may thus be adjusted to a frac-y tion of an inch and the bore .of the opening nicely regulated.
The milled and graduated portion of the sleeve 37 is formed upon a separate section from the remainder of said sleeve and is relatively adjustable so that the graduations 41 may be adjusted by rotatably adjusting the milled and graduated section of the sleeve with respect to the remaining section. This permits of adjustment to overcome wear. The sections of the sleeve 37 are held against relative movement by means of a set screw Tf desired, the inner end of the shank 15 may be internally threaded for removable engagement with the threaded end oic an eX- tension 43 and this extension may be provided with a wrench engaging portion 44, whereby the tool may be hand operated.
Through the adjustment of the sleeves 35.
and 37, the cutters may be adjusted to gradually increase the diameter of the cut until the desired diameter' is obtained.
The invention is susceptible of various changes in its form, proportions and minor details oi construction and the right is herein reserved to make such changes as properly fall within the Scope of the appended claim.
Having described theinvention what is claimed is A reamer embodying a hollow shank having diametrically opposed lugs extendingfrom its outer end, a hollow mandrel havfJ ino notches provided at its inner end to receive the lugs of the shank, said mandrel also having spaced longitudinally disposed slots the slots having inclined bottoms and a socket in ils outer end, a ring` receivable within the socket and having an annular' transversely right angular seat in one face and a beveled annular seat within its opposite iace, cutter blades arranged within the slots, heveled shoulders upon the blades to engage the beveled seat, arod mounted within the mandrel and shank, a head Vupon the outer end of the rod for position within the right angular seat, a. sleeve threadedly adjustable upon the mandrel and having an inwardly beveled edge to provide beveled engagement between the sleeve and the adjacent ends of the blades, and means to rotate the shank and rod.
