` 1 This invention-relates to improvements in `push drillsand like/tools, andhas `for a principal object `the provision of -a novel and simplied-mode of Aconstruction making possible the production ofa durable and eflicient tool of this type at a relatively low manufacturing expense.
Z'ill/lorespecifically, an objectof theinvention sto reduce the number of. the component. parts of the tool-toa practical minimum and Jto simplify.` the `forms of said vparts and the mode of assemblyithereof in the tool structure. `nlifthe. r attached drawing Figure 1 is a view showing theexternal appearance cita tool 4made in accordance with our invention'* l Fig. 2 is a fragmentary longitudinal sectional view illustrating the operating parts of the tool and the manner in which they are assembled;
Fig. 3 is a detached view in perspective of one of the elements of the mechanism;
Fig. 4 is a section on the line 4--4, Fig. 2, and
Fig. 5 is a detached view in perspective of another of the individual parts of the device.
With reference to the drawing, the tool as therein illustrated may comprise a tubular body member I, to one end of which is attached a handie 2. Partially housed Within the body member l is a threaded stem 3, this stem in operation being adapted to reciprocate longitudinally and to simultaneously rotate about its axis within and with respect to the body member. The end of the member I which receives the handle 2 is, preferably, scored on the outer surface so as to throw out longitudinal ribs 4, see Fig. 2, these ribs in assembly penetrating the interior surface of the handle 2 and thereby positively immobilizing the handle against rotary movement with respect to the body member. To this end, the handle may suitably be made of wood or other material capable of being penetrated by the said ribs. At the inner end of the handle is a metal ring or ferrule 5 which in assembly engages a split ring 6 of spring wire seated in an annular groove 'I in the body member, said ring constituting a limiting stop for the handle on the body member. A ring of this character is shown in perspective in Fig. 5. The metal ring or ferrule 5 forms a solid abutment for the handle 2. It will be noted that the end of the member I which receives the handle is interiorly threaded for reception of a screw plug 3, the function of which will be hereinafter described,
rlhe opposite end of the body member I is similarly interiorly threaded for reception of a sleeve e which embraces the unthreaded or outer portion of the-stern 3. This stem, as shown in Fig. 2, is provided with an annular groove I@ which is adapted forreception of a split ring II similar to thering Ii previously described, and this spring II of the sleeve Blimits the extent to which the stem 3 may project fromthe body member I, and in eilect locks the stemin thebody member.
suitably secured within the body member I is athreaded sleeve or cylindrical nut I2, this nut being shown in perspective in Fig. 3, and this nutcloselyembraces .the inner end of the stem 3 and meshes with the latter so that any longitudinal or axial movement of thestem in the body member must necessarily be accompanied by a rotary movement of said stem about its axis. The nut I?. in the present instance is secured in the body member by a spotweld indicated at I3. Below the nut and embracing the stem 3 is a coiled spring I4, one end of. this spring engaging an end of the nut I2 and the other end seating upon a sleeve I5 which loosely embraces the stem and bears against the locking ring I I, as shown in Fig. 2. The spring Il! thus tends to hold the stem 3 in the extended position as illustrated, but permits the stem to move axially inwardly of the body member I. When the stem is thus moved inwardly, as previously set forth, it is caused by its interengagement with the nut I2 to rotate about its axis. The outer end of the stem 3, as shown inFig. 1, is provided with a chuck I6, which may be of conventional form, for holding the drill or other bit.
The operation of the tool described above will be readily understood by those familiar with the art. With the bit in contact with the work pressure is applied longitudinally of the tool tending to force the stem 3 inwardly of the body member I. This inward movement of the stem with its accompanying rotary movement may continue until the inner end of the stem engages the screw plug 8 at the inner end of the body member. 'Ihe novelty of the device resides primarily in its simplicity of form and assembly and cheapness of manufacture. In assembling the tool, the nut I2 is first inserted into the body member I and secured therein by means, for example, of the spotweld I3. Thereafter the split ring 6 is applied to the body member, the plug 8 threaded into the latter, the ferrule 5 slipped onto the body member and against the ring Ii, and the handle 2 thereafter forced into place. The split ring I I is then placed in the annular groove I0 of the stem, the sleeve I5 and the spring I I placed on the inner or threaded end of the stem by engagement with the inner end with the sleeve l5 in engagement with the ring Il, and the stem is then inserted into the body member so that its inner end meshes with the nut I2. The sleeve 9 embracing the stem is then threaded into the body member, thereby releasably locking the stem assembly in the body. The chuck IB may be applied to the stem after or prior to assembly of the stem with the body member, but in the event that the chuck is applied to the stem before the latter is assembled with the body member, the sleeve 9 must be placed on the stem below the groove I0 before the split ring Il is seated in the groove Il). 'I'he stem assembly may readily be withdrawn from the body member for inspection, repair or lubrication by releasing the threaded sleeve 9.
We claim:
1. In a tool of the character described,thecom bination with a tubular body member, of a nut element secured in said body member intermediate the ends thereof, a threaded stem inserted in and projecting from one end of said body member and being threaded for cooperative engagement with the said nut, a sleeve embracing said stem and detachably secured at the end of said body member, an annular groove in said stem and a resilient split ring seating in said groove and adapted by engagement with the inner end of said threaded sleeve to retain the stem in assembly with the body member, a sleeve loosely embracing the stem and seating against the inner side of said ring, and a spring confined between the last-named sleeve and said nut and normally retaining the stem in an eX- tended position with respect to the body wherein the said split ring abuts the rst-named sleeve.
2. In a tool of the character described, the combination with a tubular body member, of a handle element secured to and embracing one end of said body member, a ferrule embracing the body member and forming an abutment for the inner end of the handle element, a resilient split ring seated in an anular groove in said body member and forming an abutment for said ferrule, a plug detachably secured in the handle end of said body member and embraced by said handle element, a nut element secured in the interior of said body member intermediate the ends of the latter, a stem inserted in the opposite end of said body member and projecting from the latter, said stem being threaded for cooperative engagement with the nut, a sleeve embracing the said stem and detachably secured in the end of said body member, a resilient split ring seated in an annular groove in said stem and by engagement with the inner end of said sleeve retaining the stem in the body member, a sleeve loosely embracing the stem and seating against the inner side of said split ring, and a spring embracing the threaded portion of said stern and confined between the said nut and the last-named sleeve, said spring normally retaining the stem in a relatively extended position with respect to the body member and permitting longitudinal movement of the stem inwardly of said body member to an extent corresponding to the distance between the inner end of the stem when in the extended position and the said plug.
