PUSH-DRILL.
SPECIFICATION forming part f Letters Patent No. 791,767, 'dated June 6, 1905.
i Application iledSeptember-ZZ, 1903. .Serial No. 174,211.
To @ZZ whm it may concern.; f Be it known that I, ZACHRY T. FURRISH, a
citizen ofthe United States, residing in Phila-y IO according to the size of drill used and the character of material to be drilled. In a pending application for patent, filed on the 12th day of September, 1903, Serial No. 172.9410, I have claimed, broadly, a push'- I drill having means for adjusting the spring, while the present invention relates to means located at the handle e'nd of the tool for adjusting the spring.
In the accompanying drawings, Figure 1 is 2O a side view of my improved push-drill. Fig. 2 is a longitudinal sectional View. Fig. 3 is a transverse sectional View on the line 3 3, Fig. 2. Fig. 4s is a transverse sectional View on the line 4 f1, Fig. 2. Fig. 5 is a transverse sectional View on the line 5 5, Fig. 2. Fig. 6 is a perspeotiveview of the adjusting-screw. Fig. 7 is a sectional perspective View of the handle, showing the magazine; and Fig. 8 is a sectional perspective View of the cap. 'A is the handle of the push-drill, and mounted on the end of the handle is a magazine-sec-l tion A', having a head A2, which is screwed rto the end of the tube which forms lthe hane. B is a carrier arranged to slide and turn in the handle A. A'portion of the carrier is screw-threaded, and the screw meshes with a nut a2, secured to the handle, so that when pressure is placed upon the `'handle the car- 40 rier will be turned. At the outer end of the carrier in the present instance is a chuck A spring D extends through the carrier and into the handle and rests against a nut 0l on a screw-stem D. The nut 0l has a spline d3, which enters a slot e in a tube E, secured to the head A2. The screw-stem D' has its bearing in the head A2 and is secured to a cap d2,
so that on vturning the cap the screw will be turned, causing the nut d to travel, either compressing the spring or allowing it to expand.
The magazine A has a number of compartments a for the drills. These compartments are-.formed by radial partitions, as shown in Figs; 3 and 4L. One of the compartments is 55 lled with agrooved block, in which slides a bolt I, extending to the cap @Z2 and' entering one of a series of holes in the cap. Aflanged ring f forms the bottom of the compartments a of the magazine and is supported by a spring F, which rests against a washer r1 in the end of the handle. The washer enters a notch in the bolt I, so that the spring acts to force the bolt into the holes in the cap d2. When the bolt is withdrawn, the washer rocks, and as soon as the bolt is released the spring acts to throw the bolt. y
Sliding on the handle A is a cap-ring I-I, which forms a closure for the magazine, as shown in Fig. 2. This cap-ring has a portion 7o l2., which extends into the magazine. and has a screw-threaded portion L, on which is a lianged nut Between the liange of the nut and the end of the cap is a spring-ring ha.
Out in the handle A is an annular groove, into which the ring h3 is forced by screwing up the nut when it is wished to' fasten the capring H in position closing the magazine. As soon as the nut is backed off the ring will spring out of the groove and release the cap, 8O so that it can be withdrawn from the magazine sufliciently to allow the drills to be projected by the spring F to enable any one of the drills to be removed. Other means of fastening the cap-ring to the'handle may be 85 employed without departing from the main feature of my invention.
When it is wished to drill soft material or use a small drill, the nut is backed olI by turning the cap at the end of the handle so that 9 the spring is under very little tension; but when a large drill is used or hard material is to be drilled then the Vnut is forced against the spring by turning the cap until the spring ing into the handle, a screw extendingifrom. the handle into the spring, a nut on the screw,.
means for preventing the nut turning, and a cap secured'to the screw and by which itis turned to adjust the nut longitudinally, `suzbI-fY stantially as described.
SLQThe combination of a=handle,.a carrier mountedain..thefhandle, a== nut onv the handle and a screw-thread on theicarrier soV that when the handle is reciprocated the carrier wil-l be turned, a springmounted in the carrier-'and extending into the handle, a. screw projecting from the handle, .a-cap secured. to the. screw forming` they end ofY the handle, `a nut; on` the screw, a slotted tube engaging they nuit so, that when the-screw is turned the nut will move longitudinally; and adjust the spring, substantially as; described.
4:. Thecombi-nation in afpushz-.dri'lL of alian-4 dle, a carrier, aspringresting against the caririer,.ascrew mountedin the handle of the drill,and a cap; on: the handle, to which the screw is attached so that on turning the cap 6. The combination of a handle, a screw- 45 stemmounted therein, a cap secured to the screw-stem, a carrier, a spring, a nut on the screw -stem, a bolt for locking the cap, a washer in the handle engaging the bolt, and a spring b'earing'against the washer, suhstan- 50 `tially as described.
7. The combination of` a handle, a screws stem-.mounted therein, a, capi secured-to the stem,-l ancarrier; a spring, annuton the screw` stem, .a magazine surrounding the handlewJ ring on; the handle forming thefbottom .of .the magazine, a bolt forl locking` the cap t0 .the handle, a washer inthe handle engagingthe bolt, and .aspring'mounted in they handle be tween: the ring land the. washer, substantial ly as described.`
