SPECIFICATION forming part of Letters Patent No. 585,445, dated June 29, 1897. Application filedMarch 15,1897. Serial No, 627,539. (llo model.)
To all whom it ntay concern:
Be it known that 1, JAMES LUMB, a citizen of Great Britain, residing at El1and,in the county of York, England, have invented certain new and useful Improvements in Apparatus for Lubricating I-Ieavy Bearings or Journals; and I do hereby declare the fol lowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to pumps used for lubricating bearings; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.
The object of my invention is to force or inject a continuous (and not intermittent) supply of lubricant or other liquid between those parts of the journal or hearing which are subject to the greatestpressure; and this I effect automaticallyby the use of a series of force-pumps with or without accumulators or other sources of pressure having sufficient power to force the revolving or moving surfaces apart, so that the lubricant or liquid can get freely to the parts requiring it.
In carrying out my invention I employ a series of force-pumps with one or more rams or plungers constructed practically on the principle of hydraulic rams. A portion of the framework of the apparatus ismade hollow and forms a tank or vessel for containing the lubricant or liquid, and it is conveyed therefrom by means of the pumps through hydraulic tubing direct to the journal or bearing to be lubricated.
Such being the nature and object of my invention, I will now proceed to describe the same more fully, and for that purpose make reference to the accompanying sheets of drawings, which illustrate a horizontal shaft lubricated according to my invention; but the apparatus I employ is equally applicable for lubricating the footsteps of vertical shafts or other forms of apparatus requiring lubricating, whether they be rolling or rubbing surfaces.
Figure 1 is a side view, partly in section, and illustrates one method of carrying out my invention, which primarily consists in the use of a number of force-pumps. Fig. 2 is a plan view of a part of the bearing. Fig. 3
is an enlarged elevation of the pumps, partly in section. Fig. 4 is an end view of same, partly in section; and Fig. 5 is aplan view of some of the inner parts.
1 represents the rams of the forceqoumps, connected by links? 2 to eccentrics 3, mounted upon the shaft 4, driven by spur-wheel 5 and pinion 6 and driving-pulley 7. The oil, lubricant, or other suitable liquid to be used is placed into the chamber 8, which for the sake of convenience forms part of the framework of the machine. The lubricant passes through perforated nozzles 9, through the aperture or opening 10, into the cylinder of the rams 1. The rams in their downward. motion force the lubricant or liquid in such a manner as to open valve 11, such liquid being forced through pipes 1.2 and 13 up the vertical pipe 14, when it enters through a small opening 15 in the footstep 16, a plan of which is shown in Fig. 2.
The inner side of the foot-step is recessed or cut away, as shown at 17 in Fig. 2, so that the lubricant can spread and therefore obtain greater power, so as to slightly elevate or lift and separate the revolving shaft 18 from the said foot-step 16, thus permitting the lubricant to be freely distributed, and this separation of the rolling or rubbing parts is continuous so long as the pumps are at work. boxes or chambers 19, which have also within them valves 20, which are opened by the suction of the ram 1.
In order to regulate the quantity of oil which is forced to the shafting or rolling surfaces, I employ a valve 21, which can be raised and lowered to regulate the quantity of lubricant passing through the pipes 12 and 13.
The superfluous oil or liquid which is injected to the shaftin g 18 falls into one or more dishes 22 and is conveyed therefrom by pipe 23 back again to the machine, but before doing so it falls into sieves 24, (see Fig. 4,) passing therefrom to the oil or liquid represented at 25; but in the bottom of the chamber 8 I place a quantity of water 26.
The oil flows on the top of this Water, but gritor other heavy matter which drops through the sieves 24 or which may be found in the oil will gravitate into the water, which The nozzles 9 are connected to shortgrit and heavy bodies are afterward removed by opening taps or valves 27 at the bottom of the said chamber.
To provide against accidents or breakages of the parts through the lubricant not being injected through pipes 12 and 13 when the pumps are at work, I provide an escapement or relief valve (shown at 28) adjusted to a given pressure, so that should any impediment arise to prevent the pumps forcinglubricant or liquid to the shafting the said pumps would force the lubricant or liquid through pipe 29 and through valve 28 and up pipe 30 into the sieve 24 01 oil-chamber. Consequently it is obvious that no breakages could thus occur, as the oil or liquid will simply be circulating from the chamber 8 and through the pipe 29. In combination with the force-pumps I may employ an accumulator placed in any suitable position between the pumps and the parts to be lubricated. This arrangement may be provided with a storage vessel supplied with liquid under pressure from the pumps. When the storage vessel is fully charged with liquid, the pumps may remain idle. Weights orsprings on the top of the ram of the accumulator will exertsufficient pressure'to force the liquid and separate the bearings. It therefore follows that as the pressure of liquid is continuous the separation of the bearings will be continuous, and so will be the supply of liquid. The valve 21 for regulating the supply of liquid would be employed as already described. When the storage vessel becomes empty, or nearly so, the pumps can be restarted for the purpose of again supplying the said storage vessel.
I claim as my invention- 1. The combination, with a chamber 8 for holding water and oil, of a sieve at the upper part of the said chamber, a valve at the lower part of the chamber for removing dirt, a pump arranged with its suction-pipe in the oil-space of the said chamber, a pipe for conductingv oil from the pump to the bearing to be lubricated, and a pipe for conducting the surplus oil from the bearing and discharging it above the said sieve, substantially as set forth.
2. The combination, with a chamber 8 for holdingoil, of a pump connected to the said chamber, a pipe for conducting oil from the said pump to the bearing to be lubricated, a relief-valve 28 connected to the said pipe and adjusted to rise at a prearranged pressure, and a pipe connecting the said relief-valve with the upper part'of the saidch'amber, substantially as set fort I In testimony whereof I affix my signature in presence of two witnesses.
