, PNEUMATIC-HAMMEE-OILING DEVICE.
I To all whom it may concern:
it appertains to make and use thesame.
I The invention relates to pneumatichammers and has for its object to provide an oiling device for this type of;.hammer wherein oil will be fed to the hammer working parts throughthe air passage, while the hammeris in operation, and the feedingof oil automatically-stopped when the hammer is not in operation. It hasbeen found that by supplying a constant supply of oil. to the hammer during operation that the hammer may be used under all conditions of weather without the development of various troubles incident to weather conditions and constant use.
A further object is to provide an oil receptacle interposed between the air intake port of the hammer and theair hose. Said receptacle comprising a member having an oil chamber therein, which oil chamber has passing therethrough a tubular member for the passage of air to the hammer. The wall of the tubular member being provided with apertures in communication with the chamber of the oil chamber so that as air is forced through the tubular member, said air will enter the oil chamber and force oil through one of the apertures of the tubular member into the air passage where it will be conveyed to the working parts of the hammer. Oil being prevented from flowing into the air passage when the air is cut off by the pressure within the hose line.
With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made withinthe scope of what is claimed without departing from the spirit of the invention.
. In the drawings Fi re 1 is aside elevation of a conventiona form. of pneumatic'hammer, showing the oil feed cup attached thereto.
Specification of Letters Patent,
2 is a plan view of the oil feed cup.
Fig. 3 18 a longitudinal sectional View through the oil feed cup.
Fig. tis a sectional view through the feed cup taken on line 4-4 of Fig. 2.
F1g. 5 1s an enlarged detailed sectional new of the oil feed cup tubular member.
lieferrlng to the drawings, the numeral 1 deslgnates a conventional form of pneumatic hammer and 2 the handle thereof, said handle being provided with a conventional form of finger engaging lever 3 for controlling the passageof air to the hammer. Threaded in the intake end 4; of the handle 2 is a globular member 5, which globular member is provided with a chamber 6 for the reception of oil which may be placed therein through the threaded aperture 7 which is normally closed by a plug 8. Globular member 5.is provided with a threaded extension 9 to which extension a conventional form of internally threaded hose pipe coupl ng 10 is secured. Extending longitudinally through the chamber 6 of the globular member is a tube 11, which tube has one of its ends disposed in an annular recess 12 in one end of the globular member while the other end of the tube 11 is disposed as at 13 in the threaded extension 9. The chamber 14 of the tubular member 11 forms an air passage whereby air is passed from the hose 15 to the air passage 16 in the threaded portion 17 which threads into the intake end 4 of the hammer handle.
Disposed in the hose coupling 10 and held in position by means of a shoulder 18 in the interior of said coupling is a screen 19, which screen, when the coupling 10 is threaded on the threaded extension 9, is jammed against the end of the threaded extension 9 and also against the end of the tube 11, thereby not only holding the screen 19 in position but also holding the other end of the tubular member 11 in the annular recess 12 so that the air from the hose line will pass through the chamber 14 of the tubular member 11 and air passa e 16 of the extension 17 to the intake of t e hammer.
- Tubular member 11 is provided with apertures 20 and 21.- Aperture 21 being in communication with the oil chamber 6 adjacent its lower end 22 and forms a passage through which oil passes from the oil chamber 6 to the air passage 14, from which passage the oil passes to the working parts of the pneumatic hammer. While the hammer is in Patented Aug. 23, 1921. Application filed February 18, 1920. Serial No. 359,594. I
operation the oil will be forced through the the passage 21 will be prevented by said pres sure.
From the above it will be seen that an oil feed attachment is provided for pneumatic hammers which attachment will automatically feed oil to the air passage and to the working parts of the pneumatic hammer while the same is in use. It will also be seen that when the hammer is not in use that the feeding of oil from the oil chamber 21 will be automatically cut off.
The invention having been set forth what is claimed as new and useful is An oiling device for pneumatic hammers comprising a body having an oil receptacle therein, said body member having its ends reduced and provided with axially alined air passages, one of said reduced portions of the body member being threaded, a tubular member extending through the oil receptacle of the body member and having one of its ends reduced and disposed within a counterbore adjacent one end of the body member and with the passage of the tube in axial alinement with the passage of the reduced portion of the body member, the other enlarged end of the tubular member being disposed in the passage of the threaded reduced end of the body member, a screen engaging the end of the reduced threaded end of the body member and the enlarged end of the tubular member, a shouldered member threaded on the reduced threaded end of the body member and forming means for maintaining the tubular member and the screen in position, said screen preventing displacement of the tubularmember and passages of communication between the air passage of the tube and the oil re ceptacle whereby air will enter the oil receptacle and force air into the air passage of the tube.
In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
