INVENTOR f l CHARLES-.n n'. LLOYng-GFLos ANGELES, 'CALIORIA LUBncArlne iuncneinsiu.
lTo all whom it may concern:
Be it known that I, CHARLES E. H. LLOYD, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Lubricating Mechanisms, of which the following is a specification.
My invention relates more specifically to a mechanism for delivering lubricants to the moving parts of engines or other mechanisms during their operation. v
The prime object of my invention is'to provide a power driven mechanism that will successively and intermittently deliverauniform charge of lubricant from a plurality of discharge ports to the working parts'of mechanisms requiring such lubrication.
Another object of my invention is to provide a lubricating mechanism in which the lubricant discharge ports will visually indircate the discharge fof lubricants there-` Y sure regulating means, whereby the lubricant which is being forced through the mechanism will at all times be maintained under a uniform pressure.
A final object is to provide a simple and eificient mechanism that is unlikely to get out of order during an operation and which will be positive in its operation.
I accomplish the above objects by means of the mechanism described herein and illustrated in the accompanying drawings, in which: l

essary'v for their efficient operation.
Heretofore the main difficulty experienced with such mechanisms is that they do not deliver the exact quantity required and,

i with the exact quantity of lubricant nec-r moreover, the pressure cannot be regulated so' that the same is uniform. y Y
means of my' mechanism I am enabled to deliver lubricants successively and intermittently from a plurality of portsto Vthe various working parts of mechanisms in the exact quantity required, and to maintain at alltimes a uniform pressure of the lubrilcant passing therethrough. f v
Referringmore particularly to the drawj ings, my mechanism preferably consists of a rectangular metallic housing 5 having a bottom wall 6, top wall'7, side walls 8 and 9, and-removable end closure plates 10 and 11,
said plates being secured to the housing in 4 any suitable manner. Y
The operating mechanism which principally'cons'ists of a feeding and distributing means is located within housing 5 which is here Vshown as rectangular vin form. The bottom wall 6 and the lower portion of side wall 8 are considerably thicker than the other walls and are provided with longitudinally extending bores 15 and 16. Rotatabiy mounted in bore 15 is a feed screw 17 preferably provided with square threads arranged in helical form extending throughout its entire length with the exception of One end vof screw 17 is provided with a stem 18 which extends through a packing box 19 of usual construction mounted in end plate 11, and has secured theretoV a driving pinion 20, the stem being connected to a suitable source of power (not shown). f
Mounted in the otherbore 16' is a hollowY lubricant discharge cylinder tube 22, one end being provided with a stem yor shaft 23 which extends through a packing `box 24, the end of the stem having a drivenV in helical form. These ports, when the dis-f charge cylinder is rotated, register successively with a plurality of threaded ports or openings 27 formed in the lower portion 1of wallv 8 of the housing.- Y I once apparent that I have provided a power driven lubricating mechanism that forces the lubricant through the discharge ports in cylinder 22 in an even and uniform manner, the indicating devices showing the operator at a glance each discharge of the lubricant therethrough.
What I claim is:
l. A lubricating mechanism, comprising a fluid chamber, a rotary fluid pumping means mounted in said chamber, a fluiddistributing means also mounted in said chamber, said distributing means connected to said pumping means and adapted t0 deliver fluid from said chamber intermittently, and means to operate said pumping and distributing means.
2. A lubricating mechanism, comprising a fluid chamber, a rotary fluid pumping'means mounted in said chamber, a fluid distributing means also mounted in said chamber, said distributing means connected to said pumping means and adapted to deliver fluid from said chamber, means to relieve eXcessive pressure of the fluid passing through said distributing means, and means to operate said pumping and ldistributing means.
8. A lubricatingmechanism, comprising a fluid chamber, a fluid pumping and distributing means mounted in said chamber adapted to deliver fluid from said chamber intermittently, means to relieve excessive pressure of the fluid passing through said chamber, said chamber being provided with a plurality of ports in one wall thereof adjacent said distributing means, a fluid indicating device connected to said ports, said device adapted to visually indicate the passage of fluid through said ports, and means to operate said pumping and distributing means.
4l. A lubricating mechanism, comprising a fluid chamber, a fluid pumping means mounted in said chamber, a fluid distributing means comprising a rotary cylinder provided with a plurality of ports arranged in helical form, said chamber adjacent said distributing means being provided with a plurality of outlets adapted to register with the ports in the distributing means, whereby fluid will be delivered from said distributing means through said bores inteiniittently and successively, means to relieve the excessive pressure of the fluid passing through said distributing means, and means to operate the pumping and distributing means.
5. A lubricating mechanism7 comprising a casing forming a lubricant supply chamber,
la rotaryv ylubricant pumping means mountedl in said chamber, a valve distributing means mounted 1n said chamber and connected wlth said pumping means, said d1str1but1ng vmeans adapted to deliver lubricants succescent said pumping means and connected therewith, a wall of said chamber being provided with a plurality of lubricant discharge ports, said ports communicating with said distributing means, and means to operate the pumping and distributing means simultaneously.
7. In a mechanism of the class described, a fluid chamber having a pair of longitudinally inclosed cylindrical bores therein, a screw pump rotatably mounted in one of said bores, a cylindrical fluid distributing tube having a plurality of outlets arranged in helical form mounted in the other of said bores, said bores communicating at one end thereof, the pumping bore having a fluid inlet leading from said fluid chamber, a spring pressed valve for relieving excess fluid pressure connected to said bores, means for regulating the tension of said spring pressed valve, a plurality of fluid outlet tubes mounted in a wall of said chamber and registering with the outlet formed in the distributing tube on arotation thereof, said outlets in said tube registering with outlet tubes successively, valve means mounted in said outlet tubes to regulate the discharge therefrom, an indicating means mounted on each of said outlet tubes to indicate the discharge of lubricants through said tubes, and means to drive said screw pump and distributing tube simultaneously.
8. A lubricating mechanism, comprising a fluid supply chamber, a rotary fluid pumping means mounted in said chamber, a rotary fluid distributing means mounted in said chamber and in communication with said pumping means, and means to operate said pumping and distributing means. y
In Witness that I claim the foregoing I have hereunto subscribed my name.
