FLUID-FEEDING- ATTACHMENT EOR HQLLQW DRILI -STEELS.
Speciflcation of Letters Patent.
Patented Aug. 5, 1913.
Application filed January 19, 1909, Serial No. 473991.
To all whom it may concem:
Be it known that I, WILLIAM PRELLWITZ,
a citizen of the United States, and resident position on the steel by the pressure of the fluid, and in which the pressure of the` fluid serves to form automatically a fiuid-tight connection between the attachment and the hollow drill steel. L
This invention consists more particularly in a fluid feeding-nozzle having an annular chamber in. open communication with the fluid supply and with the interior of\the hollow drill' steel; the inner walls of the.
nozzle being forced snugly against the drill steel by the pressure of the fluid wthin the said annular chamber.
A practical embodiment. of my invention is represented in the accompanying drawings, in which- F igure 1 represents a hammer drill in side elevation with 'the improved fluid feeding attachment applied thereto, F g. 2 is a detail View taken at right angles to Fig. 1, Fig. 3'
is a section taken in the plane of the 'line A-A of Fig. 1, looking in the direction of the arrows, Fig. 4 is a section taken in the plane of the line B-B of Fig. 2, looking in the direction of the arrows, Fig. 5 is an enlarged detail plan View of the attachment, Fig. 6 is a section taken in the plane of the line C-C of Fig. 5, looking in the direction of the arrows, F ig. 7 is a plan View of a modified form of attachment suitable for use in connection with round, hollow drill steels, and Fig. 8 is a section taken in the plane of the line D-D of Fig. 7 looking in the direction of the arrows.
The hollow drill steel is denoted by 1' and its longitudinally arranged axial bore by 2. Transversely arranged holes 3 lead from the bore 2 through to the egterior of the drill steel at a distance from its striking end and at a point beyond the drill.
The fluid feeding attachment' comprises a hollow nozzle having a fluid inlet tube 4, outer walls 5, inner walls 6' and an annular chamber 7 formed between saidouterand.
inner walls. j
The inner walls 6 of the nozzle are fitted to embrace and snugly 'engage the hollow drill steel land holes 8 are formed through the inner wall 6 so that when the nozzle is 1n proper position, open communication is established from the annular chamber 7.
through the holes 8 in the inner walls 6 and the holes 3 in the drill steel to the longitudinal bore 2 of theo said drill steel.
The inner walls6 of the nozzle are elastic and are shaped to conformto the exteriqr of 'the drill steel in' connection with which the attachment is to be used.
The whole nozzle may be formed of rubher and may be strengthened, if so desired, by ncorporating therein an annular series of longitudinally arranged stiflening pieces 9 of 'metal or 'other desired material which pieces serve to connect the outer and inner ends of the sa'id nozzle.
It will thus be seen that the fluid which is being fedtto the interior of the holl'ow drill steel through the nozzle, will exert its pressure on the inner walls 6 of the nozzle to hold the walls snugly in engagement with the drill steel and thus serve the double purpose of making a fluid-tight connection between the nozzle and the drill steel and also of tending to hold the nozzle in position on the steel.
Additional means may be employed for preventing the undue displacement of the the drill cylinder 13 so that the stop when swung into its operative position will engage the drill steel at a point a slight distance beyond the nozzle.
The tendency of the . branches 11, 12, to spring toward-each other will yieldingly hold their inwardly turned ends 14, 15, in engagement with their sockets in the front end of the drill cylinder 13. 4
In Figs. 1 to {6 inclusive, the nozzle is shown as adapted for use in connection with a drill steel of angular cross sectionand in Fig's. 7 and 8 as being adaptedfor a drill steel round in cross section but it is to be understood that this nozzle is to be so made that its inner walls. will fit steels of any cross sectional shape.
It will be seen that the tube 4 of the nozzle will form a suitable handle for assisting in the manipulation of the drill. It will also be noted that where a drill steel round in cross section is used, the steel could rotate within the nozzle without destroyng the fluid tight connection between the steel and nozzle.
What I claim is 1. A fiuidfeeding attachment for hollow drill steels comprising a nozzle of elast-ic material having inner and outer walls inclosing an annular chamber, its nner wall being arranged to be held in fluid-tight engagement with the steel by the pressure of the fluid within the chamber, and stifi'ening peces incorporated in said nozzle.
2. A fluid feeding attachment for hollow drill steels comprising a nozzle of elastic material having inner and outer walls inclosing an annular chamber, its inner wall being arranged to be held in fluid-tight engage ment with the steel by the pressure of the fluid within the chamber and an annular series of longitudinally arranged stiflening pieces incorporated in said nozzle. .4
a 3. The combination with a drill and its hollow steel, of a fluid feeding attachment for the steel comprising a nozzle having integral inner and outer walls inclosing an annular chamber, the inner wall being elastic and arranged to be held in fluid-tight engagement with the steel by the pressure of the fluid within the chamber, and a stop carried by the drill for preventing the displacement of the nozzle.
4. The combination with a drill and its hollow steel, of a fluid feeding attachment for the steel comprising a nozzle having integral inner and outer walls inclosing an annular chamber, the inner wall being elastic and arranged to be held in fiuid-tight engagement with the steel by the pressure of the fluid within the chamber and a Swinging stop carried by the drill for preventing the displacement of the nozzle.
In testimony, that I claim the foregoing as niy invention, I have signed my name in presence of two witnesses, this eighteenth day of January, 1909.
