STATES PATENT UlFl l-i BYRON ll: WELLER, OF FRANKLIN, PENNSYLVANIA.
COMBINED FACING TOOL AND CGUNTEREORE.
Application filed February 23, 1907. Serial No.
I '0 all whom it may; concern:
Be it known that l, Brno: M. WELLER,
citizen of the United States, residing at reference being had to the accompanying drawings which form a part hereof, and in which v Figure 1 is an elevation of the usual form of my device. Fig. 2 is an elevation of the same Without the reinforcing collar. Fig. 3 is an elevation of same with a long cutter and an enlarged reinforcing collar or sleeve. Figs. 4, 5 and 6 are end views. Fig. Tie a vertical section of the lower portion of the arbor and the pilot-bushing, showing the Fi 8 is a perspective view of the lower end oi the arbor.
The construction of my improved counterbore and facing tool is substantially as follows:
1 construct an arbor 1,, which is provided upon its upper end with asuitable shank 2, adapted to the Jul-pose of holding and driving the tool z T he lower end is preferably reduced in diameter at R,.foi the purpose of enabling the tool to operate upon areas smaller than the area of the arbor 1, through said reduccd portion R, is formed a slot 3,for the reception of cutters 4, 4" and 4"; said slot 3 extends upward a short distance beyond the shoulder R for the purpose of forming a more extended bearing upon the upper edge of the cutter.
Below reduction R, is formed a pilotpoint or hearing B, for the reception of the pilot bushing 5, which is revolubly mounted upon said poin t: Extending longitudinally through point B, and'in'to the cutter-slot 3 is a tapped hole 6, for'the reception of a set-screw 7, the
upper point of which bears against the lower.
edge of the cutter and secures the same in i'iSlElOIl.
Thepilot bushing 5of which there may be various sizes of, 5 is retained upon the point B by the washer 8 and nut 9, which nut screws upon the set-screw 7 and serves as a lock nut thereto; the diameter of bushing 5 Specification of Letters Patent.
l' atented. Aug. 25, 3.90%.
may vary, as aforesaid, to suit the size of the hole H, .(Fig. 1) which-the pilot is required to enter to fill.
Upon the arbor 1v is mounted a reinforcing sleeve 10 or 1'0, the lower edge of which is formed into s iral lips L, L, the long vertical faces of whicii bear respectively against the back side of each end oi the cutter to back it up or strengthen it against the cutting or working strain.
In this construction, by usinga pro erly proportioned sleeve, it becomes possibie to use long cutters in a comparatively snnillarbor, as shown in Fig. 3. Said sleeves are made non-revoluble upon arbor 1-, by seen? ing a feather 11 in the interior wall oi tl'ie sleeve, adapted to occupy the seat 12. The sleeves are adapted to have a certain amount of ldngitudinal adjustment upon'the arbor, and to secure said sleeve at the proper position of said longitudinal adjustun-nt, a set screw 13 passes through said sleeve, at the side opposite to feather 11, and bears against the arbor. When the cutter becomes narrow, from rinding, it becomes necessary to raise thes' e'eve, so that the lips L will not project below the cutting edge of the cutter; the object of the longitudinal adjustment of said sleeve 10 is thus obvious.
In order to efi'ectually prevent a chattering or vibration of the tool 4, it is necessary that that portion of the reinforcing sleeve 10 which bears against the back side of said tool, should extend down into close pros.
imity to the cutting edge of the tool: if, how i ever, said sleeve were made straight across the lower face, the accumulation of chips or borings beneath the same, especially in the form shown in Fig. 3, would materially interfore with the work of the tool, and it is for the urpose of overcoming this difficulty that the ower face of sleeve- 10 is made spiral, and
which constitutes an essential feature of my invention.
In tools of this type, the work to be done,
is of the character shown in Fig. 1, that is, the
material surrounding holes of a compare tively small diameter, is to counterbored or spot-faced at one or both endsof thollole,
and in order to have the counterborcor spotfacing concentric with said hole; there must be a pilot u on the end of the tool-to enter and fit said ole (Hlcloaely.
Intools, as at "esent constructed, the pilot is integral wit the arbor and revolves in the hole, and it is a common occurrence times breaks the pilot; this also interferes with the proper Working of the putters. With my construction, the dot-bushing does not revolve in the hole, snc therefore, is not subject to the conditions and objections above stated, hence, it is much essier'to o'perste, and all torsion, incident to driving the usual form of pilot, is eliminated, which is especially advantageous, when it is considered thatflsrieh torsion Inustlergely be sustained. by the reduces portion R of the arbor. ltis also obviousethet the reinforcing sleeve it) will relieve said reduced portion R'of all strain i'ncident to driving the cutter, hence will be readily understood that the reinforcing sleeve and the revoluble pilot -bushing cooperate toeliminete the torsion upon said reduction R, hence said reduction may be smaller than in the usual form of tool, and
the limit of working area of my tool becomes.
\ much greater, than in the usual 'form ofsenses? counterboi ee is a valuable "festiire of my invention,- for thereason that one arbor of my construction, will cover a range (if Work thet'it has heretofore required several erbors to accomplish.
Having thus described in l claim and desire to secure i;
invention, what y Letters Patent in s,- combin'ed counter-bore and facin tool, on arbor having a shank at one e115 thereof there being a. cutter-slot through said arbor approximate to the other end, a nutter in said slot, a reinforcing sleeve nonrevolubly mounted upon said arbor, there "beii'ig spirel lips upon said sleeve, each lip having. a vertical face adapted to bear swsinst the back sideof the respective ends 0i said cutter for the pu ose specified.
