Application filed March 28, 1923. Serial No. 628,172.
To all whom it may concern:
Be it known that I, LEWIS C. BAYLES, a citizen-of the United States, a resident of Easton, county of Northampton, and State of Pennsylvania, have invented a certain Oiling Device for Rock Drills, of which the following is a specification, accompanied by drawings.
This invention relates to fluid actuated rock drills, more especially of the hammer type, but relates in particular to an improved oiling device for. such machines,
' which may be located in any convenient part of the machine, but preferably in one of the front end parts.
The objects of the invention are to improve upon such devices, by simplifying and cheapening the construction and at the same time, secure an efficient oiling device, located within the machine and capable of continuously supplying lubricating material to the adjacent moving parts of the machine.
Further objects of the invention will hereinafter appear, and the invention is shown in one of its preferred forms in the accompanying drawings, in which Figure 1 is a longitudinal sectional elevation of so much of a rock drill as will serve to make the invention clear,
Figure 2 is a detail plan view of a metallic holder for a ring of absorbent material, forming a part of the oiling device,
Figure 3 is a detail end view in section of a ring of absorbent material and metallic holder surrounding it,
Figure 4 is a detail perspective view of a tang for securing the ends of the metallic holder together. 7
Figure 5 is a detail view in transverse section of the front cylinder washer showing a modified form of my oiling device applied thereto, and
Figure 6 is a detail end view in section, of the oiling device shown in Figure 5.
Referring to the drawings, A represents the cylinder of a fluid actuated rock drill of the hammer type having a front head B into which the lug shank of the drill steel G extends in position to receive the blows of impact of the hammer piston D having a fluted forward extension E.
In this instance, the rock drill is assumed to have automatic rotation devices for the drill steel, the usual rifle bar and associated elements for rotation, not being shown. The forward extension E of the piston extends through the front cylinder washer F and V the flutes Gr engage the chuck nut H in the chuck J, suitably clutched to the chuck key K in the front head B. The ports and passages for the distribution of motive fluid for actuating the piston D in the cylinder A are omitted, as they are notnecessary for an understanding of the present invention. In accordance with thepresent invention, the front cylinder washer F is provided with an external circumferential groove L communicating with the internal parts of the machine through the inner groove or pocket 0 and passages P and Q. The inner groove or pocket 0 extends circumferentially of the front cylinder washer. It has been found in the operation of rock drills, when absorbent material is placed in the groove L, without the provision of any inner groove or pocket, that the absorbent material soon disintegrates, due to the velocity of the motive fluid passing out through the small passages, which soon become clogged, thereby preventing flow of lubricating material to the front end parts of the machine. The groove or pocket 0 serves to reduce the velocity of the motive fluid passing out from the external groove L, thereby preventing this disintegration of absorbent material. The absorbent material B may be in the form of a piece of felt, but I do not desire to have this absorbent material fill the entire area of the groove L in the front cylinder washer F. I provide a flat apertured' or perforated metallic holder S for the piece of absorbent material, preferably of thin sheet metal within which the absorbent ma terial is held. Oil is supplied to the external groove L after removing the oil plug T in the usual manner. The apertured or perforated metallic holder S and absorbent material R, together form an oiling device. Slots U are preferably formed in each end of the metallic holder S into which the tang V may be inserted and bent over, to form a securing device for the ends of the holder.
In the modification shown in Figure 3, the absorbent material R is held together in any suitable manner in the groove L by two apertured or perforated metallic holders V and W. It will be noted that in the forms shown in Figure 1 and Figure 5, the metalhe holders and absorbent material are of substantially the same Width the external groo e L.
The absorbent material ll becomes saturated with oil which is drawn or fed into the moving parts of the machine in the front head, during the operation of the machine. The motive fluid r the machine may enter the space forming pocket be tween the metallic holder and the cylinder, and the pressrr thus built up will force the lubrica material out of the external groove L t rough the pocket '8 and into the moving narts of the machine.
