sra/ING SINKERHANDLEFORKDEIETERSL` Application mea oct'oer 5, 192,5. vseriaig-Nbconosl 1 l To all ywhom it `'may concer/n.5 Y w Beit known that I, CHARLES dent of Easton, county of Northampton, and State of Pennsylvania,have invented-a certain Spring Sink'er Handle`fforDrifters,VV
of' which' the following is specification accompanied by drawings.
This'invention relates to rock drills but more particularlyv to a meansV for converting n a hammer drill ofthe A"drifter,t'y'peinto va hand-held drill of. the' 4sinker.A or plunger type.' r V Hammer Vdrills 4of the aforesaid Leyner. or drifter type are vintended tobe used mounted on either columns, tripods, -or
quarry bars,' and vare not 'equipped' with handles for manual operation in vertical4 Due to their greatvwelght' down drilling. v it is rusually impossible to use them without somesuch support as a tripod. or column.
But inthe case ofl thelighter` drifters, yweighing 125 lbs. or less,k without' the cradles, it is often desirable `to use `these drills as sinkersfand pluggers, and thus out down on the equipment. necessary 1 fo'rla small quarryl orfexcavating job.
Oneofv the obyects of this invention,rthere, fore, is to provide a simplerugged, detach,- a-ble handle Ifor use with a lighttrock drill of,the;Leynei"7 o-r-drifter type. 1 Y
Another object of vthis invention *listoy providel a handle which, through its simplicity, may be quickly and conveniently applied to the rock drill, Vwithoutany appreciablev loss oftime. A third object of this invention is to provide an easily attachable handle for the aforesaid type of drill which will also absorb a great deal of the vibration and kick back of the piston, which is very considerable with a drill of the drifter type and which would otherwise be transmitted to the hands and arms of the operator, mak-l ing the drill vdiiiicultto operate.
My invention consists of thecombination'y Figure 2 is a detailed' vertical sectional view of the handle and so much of the drill as will serve to make the invention clear,

HANSEN,v` a citizenl of the 'United States, and aresiof apercussivefluid actuatedy rockd-rill'is held in fixed relation'lto the-backand 'front heads B land C respectively vby 'means ofthe customary side bolts D, which engage ifthe .lugs onl thev front lhead and the, lugs f. F (shown in iFigureQI) on-the back head.y
These lside loolts D 'in turnarefittedwith Athe usualcoil springs and double locknuts'and .-j
Washers, which howeverl do not enter into the invention.. o The cylinder vAhascast integral with it the usual slides or ribs G intended tomiit into the grooves provided in the; cradle ofa drifter mountingfor. the
fdrill. lThe yhandle itself consists of rthree' general Velements asfollowsthe bracketsll, legs J and cross handle bar X. The brackets HaareY cylindrical in formi andy grooves4 K 1 have been cut in `therngtofit over the ribs or slides'G of thefdrillcylinder, Retaining lugs L are alsogmade integral lwith the .brackets forjengagem'eiitv between the 'back v head lugs F, and the heads of the'qside lbolts 11 f D.v A ,crossfbrace ZOU?y between the, two

brackets H'lpreferably attached to; v the brackets by bolts serves to strengthen the brackets in, relatie'n tqeach, other.v 'The brackets-H have fhollow bores to receive'tlil handle legs J which are likewise preferablyV Vhollow and threaded in the inside bores Q.
In the assembly thereof the legs J enter the bores of the brackets H at one end, and are heldin place by threaded studs R, which enter and engage the threaded bores Q, of the legs and are held in relation to the brackets H by means ofthe stud .nuts S.: Coil springs T 4are Valso insertedA in the bores of they brackets H, and are compressedbetween-the bottoms'of the legs J and the shoulders in the bore of the brackets H. The legs J are suitably attached to the hollow cross handle bar X which may be covered with some resilient material such as rubber hose.v A handle rod VV' of any Vpreferred4 length extends through the cross handle bar K and is fitted at both 'ends with the'nuts W. -The application of this handle to a drill and its use therewith is asfollows: Assumingthat a drill of thev Levnerlor` 1 drifterr typev is lto ybe usedas a hand-held drill, the operator first backs it oft' its cradleA t to the.v general elements of the lcombination whichprovide for the"v adequate bracing oill thejhandle against theditferent longitudinal and. vertical strainsjset up by'y its mede-fof Asi;
by means of the usual crank attached-to ythe y cradle. .He then loose'nsthey sidebolts D withdraws'them, and holds the drill'prerf'erably in a Vertical positionwith its back head B uppermost; As a yconvenient mode of as-L semblage the brackets II,f assemblcd kwith legsJ,the crossbar K, and the cross brace;
O may "then runV over-'theslides 0r ribslGr untilv the retaining ylugs L stop' against Vthe lugs E and are drawn up` tight.` Thefdrill drill maybe used. 'anrnot totbennd'er? stood .as limiting my, inventionpto the exact and precise details'foi' the drawings butinore use.'v Y
