ROTARY TOOL.

Specification of Letters Patent.

Patented June 26, 1906.

Application filed October 22, 190A. Serial No. 229,543-

To all whom it may concern:

Be it known that we, ELIAS R. WILNER, a resident of the borough of Manhattan, city, county, and State of New York, and LEON SUSSMAN, a resident of Bayonne, Hudson county, New Jersey, citizens of the United States, have invented certain new and useful Improvements in Rotary Tools, of which the following is a specification.

Our invention relates to rotary tools, particularly such as are used in connection with so-called "drill-presses, and has for its object to provide an adjustable construction of the frame, so that heads of various lengths may be applied thereto.

Other features of our invention will ap pear from the description and claims following hereinafter.

Reference is to be had to the accompanying drawings, in Which- Figure l is a sectional elevation of a drill press embodying one form of our invention. Fi 2 is a sectional plan on line 2 2 of Fig. 1. Fig. 3 is a sectional elevation of the lower end of the structure, drawn upon an enlarged scale. Fig. 4 is a side elevation of the parts shown in Fig. 3. Fig. 5 is a face view of one of the pinions forming part of the driving-gear. Fig. 6 is a sectional elevation showing a somewhat different manner of holding the cutter-shaft in position. Fig. '7 is a face view of the member which holds the cutter-shaft. Fig. 8 is a sectional elevation of a drill-press embodying another form of our invention. Fig. 9 is a side elevation thereof, and Fig. 10 is a sectional plan on line 10 10 of Fig. 8.

Referring to the form of construction illustrated by Figs. 1 to 7, A designates the customary arm of the drill-press, in which the head is movable up and down. For this purpose there is provided a shaft C, carrying a pinion C, which meshes with the rack B on the sleeve B of the head, the shaft being turned in the usual way by means of a crank or a key. (Not shown.) The head comprises the sleeve B and the chuck or spindle coupling D rotatable therein, said coupling having a flange D at the bottom, a conical cavity to receive the tapering end E of the spindle E, and a transverse aperture D which is adapted to register with a similar aperture in the sleeve B and serves for the introduction of a wedge or like tool used in driving the spindle E out of the coupling or socket D. The extremity E of the spindle E is flattened or angular, and the corresponding portion of the socket is of like shape. Nuts F F, screwed on the upper portion of the coupling D against the end face of the sleeve B, serve (together with the flange D) to prevent any end movement of the coupling. The lower portion of the spindle E is received in a casing G. The upper end of this casing has a guide G for the lower end of the rack B, so as to properly aline the casing with the upper portion of the machine. The rack B, located at the side of the sleeve B, gives the said sleeve an angular cross-section, and as the said rack projects into the guide G of the casing G it serves to also prevent the casing G from turning relatively to the sleeve B. The lower end of the casing G has a chamber G closed at one side by a plug H, which receives one end of a transverse shaft I, carrying at its other end a cutting-tool J of suitable construction. As shown, this tool projects laterally from the cylindrical surface of the casing G.

On the shaft I is mounted detachably a bevel-pinion K, meshing with a similar pinion E on the spindle E, and having an elongated recess K to receive a flat portion I of the shaft, whereby the shaft and pinion are caused to rotate in unison normally; yet the shaft may be withdrawn lengthwise to free the pinion. Adjacent to the cutter J the shaft has a conical portion I adapted to be seated in a bearing-ring made in two separable sections L L, held in the casing by a pin M and a screw N respectively. The bearing-ring is thus securely held at the top and at the bottom, but may be readily removed when desired. The casing G is preferably forked where it forms the guide G, and a screw G is employed to hold the casing on the sleeve B.

In operation the cylindrical shank of the casing G is introduced into the bore of a part which it is desired to provide with a longitudinal internal groove. Thus the device 'can be used for cutting a key-groove on the inner surface of a sleeve intended to be fitted on a shaft. The rotary tool J will cut the required groove, While the cylindrical shank of the casing will fit closely within the bore of the sleeve, and thus hold the tool and work in proper relation. An important advantage of the construction above described is that it provides a relatively inexpensive grooving-tool capable of attachment to an ordinary drillpress.

Figs. 6 and 7 show a slightly different con struction for enabling the cutter-shaft to be easily removed. Here the shaft I is journaled at one end directly in the casing G and at the other end in a bearing-ring L the outer diameter of which is at least equal to that of the bevelpinion K. At its central portion the shaft 1 has a peripheral groove I", which is engaged by the recessed and flattened end portion N of a plug N, secured in the bottom of the casing G by a pin 0. This construction, like the one first described, possesses the advantage of allowing cutters of various characters to be readily substituted for one another.

In the form of construction illustrated by Figs. 8, 9, and 10 the casing which is connected with the sleeve 1) of the head having the rack b is constructed in two superposed. sec

tions 9 g, the distance between which may be varied. This is done for the purpose of enabling the same attachment to be used either with short heads, such as the one shown in Fig. 1, or with long heads, such as shown in Figs. 8 and 9. The upper section 9 is constructed very much like the upper end of the casing G in Fig. 1 and has a guide 9 for the rack part b of the sleeve 7) and a fork g, the members of which are connected. by the screw g which holds the attachment upon the head of the drill-press. Vertical bolts 10 are screwed into or otherwise fastened to the lower section 9, and the screw-threaded upper portions 17 of these bolts extend loosely through openings in the upper section g, which. is held at the desired distance from the lower section by means of nuts 19 19 Any other approved arrangement may be employed for adjustably connecting the two sec tions 9 g. The lower section 9 may be constructed in substantially the same manner as the lower portion of the casing G in Figs. 1, 3, or 6; but in Figs. 8 and 9 we have illustrated a somewhat different construction. Here the shaft 11, which is connected with the coupling (1 in substantially the same manner as described with reference to Fig. 1, carries at its lower end a bevel-pinion 1c, meshing with apinion 9 which is j ournaled on a stud r, and the pinion g is again in mesh with a pinion s, which is mounted loosely upon a spindle t, the upper end of which extends loosely into a suitable recess of the bevel-pinion 7c and of the shaft The lower end of the spindle t is connected with a chuck it of any suitable con- F struction. The spindle t is movable lengthwise and is provided with a clutch device which connects said spindle for rotation either with the pinion k or with the pinion s. For instance, the spindle may be provided with a pin 25, adapted to engage a set of pins k or 3, according as the spindle is moved up or down. It will be understood that by this mechanism we are enabled to cause the chuck u to rotate in either one directionor the other, while the shaft I and train of beveled wheels 7c g 8 always turn in the same direction.

I/Vhat we claim as new, and desire to secure by Letters Patent, is

1. Ina drill-press, an adjustable head comprising a sleeve having a rack and a spindlecoupling rotatable in said sleeve, acasing having means for connecting it to said head and provided with a guide arranged to engage said rack to prevent the casing from turning relatively to the head, and an operating-shaft coaxial with the casing and operatively connected with the spindle-coupling of the head.

2. In a drill-press, an adjustable head comprising a sleeve having a rack and a spindlecoupling rotatable in said sleeve, a casing comprising anupper section adapted for attachment to the head, a lower section adjustable relatively to the upper section lengthwise of the head, said upper section having a guide arranged to engage said rack to prevent the casing from turning relatively to the head, and a tool-operating shaft ournaled in said lower section and adapted for driving connection with the spindle-coupling of the head. i

3. In a drill-press, an adjustable head com prising a sleeve having a rack and a spindle coupling rotatable in said sleeve, a casing having means for connecting it to said head and provided with a guide arranged to engage said rack to prevent the casing from turning relatively to the head, and an operating-shaft operatively connected with the spindlecoupling of the head.

4. In a drill-press, an adjustable head com.- prising a sleeve having a rack and a spindlecoupling rotatable in said sleeve, a casing comprising an upper section adapted for attachment to the head and a lower section adjustable relatively to the upper section lengthwise of the head, said upper section having a guide arranged to engage said rack to prevent the casing from turning relatively to the head.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
