Jan. 22, 1963 s. w. CLUTTON on WELL JOURNAL BOX DUST GUARD Filed NOV. 3, 1960 jim BY ATTO R N EYS.
United States Patent Ofilice 3,974,729 Patented Jan. 22, 1963 3,074,729 OIL WELL JOURNAL BOX DUST GUARD Sam W. Clutton, P.O. Box 1104, Great Falls, Mont. Filed Nov. 3, 1960, Ser. No. 67,080 4 Claims. (Cl. 277--26) This invention relates to a railway journal box, and more particularly to a means for preventing overheating of the railway journal box.
This invention is an improvement on the grease well journal box dust guard of my prior Patent No. 2,497,864, dated February 21, 1950.
The primary object of this invention is to provide an oil well journal box dust guard which has incorporated therein pressurized reserve oil containers which are positioned so that a reserve of journal box oil will be sprayed on both the journal and journal lubricator in order to prevent hot box or prevent or minimize the possibility of railway journal box overheating.
Another object is to provide an improved oil well journal box dust guard which has incorporated therein pressurized reserve oil containers which have spray nozzles so that when heating occurs, fusible or alloy plugs will be melted away to uncover the spray nozzles. whereby a reserve of journal box oil will be effectively sprayed on both the journal and journal lubricator in order to prevent overheating of the railway journal box and its associated parts.
Still another object is to provide such an oil well journal box dust guard that is rugged in structure and foolproof in operation and which is economical to manufacture and efficient in use.
These and other objects of the invention will become apparent from a reading of the following specification and claims, together with the accompanying drawings, wherein like parts are referred to and indicated by like reference characters and wherein:
FIGURE 1 is a vertical sectional view taken through a railway journal box and showing the improved dust guard of the present invention mounted thereon.
FIGURE 2 is an elevational view of the oil well journal box dust guard per se, and with parts broken away and in section.
FIGURE 3 is an elevational view looking at the opposite side from that shown in FIGURE 2.
FIGURE 4 is a sectional view taken on the line 44 of FIGURE 2.
FIGURE 5 is a sectional view taken on the line 55 of FIGURE 2.
FIGURE 6 is a perspective view of one of the pressurized reserve oil containers.
FIGURE 7 is a fragmentary enlarged sectional view showing the spray nozzle in the lower portion of a pressurized reserve oil container.
Referring in detail to the drawings, the numeral 10 indicates a portion of a conventional car axle which includes the usual journal portion 11 that bears on a brass 12, and the numeral 13 indicates a journal box of a suitable construction, and the journal box 13 is provided with a slotted portion 14. According to the present invention there is provided an improved dust guard or protector which is indicated generally by the numeral 15, and the protector 15 includes a body member 17 which is provided with a circular opening 16 for the projection therethrough of the car axle.
The body member 17 is provided with a pair of spaced apart chambers or recesses which are each indicated generally by the numeral 18, and the numeral 19 indicates each of a pair of pressurized reserve oil containers which are shaped to conform to the configuration of these chambers 18, and the containers 19 are snugly positioned or seated in the chambers or recesses 18 as shown in the drawings. Each of the containers 19 has the same construction and each includes outer and inner wall portions 20 and 21 as well as an arcuate wall portion 2 and a curved wall section 23. The lower portion of the wall 20 is recessed inwardly as at 24, and a spray nozzle 25 is mounted in the recessed portion 24, FIGURE 7, the spray nozzle 25 being provided with an aperature or opening 26 whereby oil such as the oil 28 can selectively flow out through the aperture 26. The numeral 27 indicates a fusible or alloy plug which is normally arranged in covering relation with respect to the opening 26, but in the event that the journal box starts to heat up, the plug 27 will melt in order to uncover or expose the opening 26 so that the oil 28 can flow out through the opening 26 in order to spray the reserve oil 28 on both the journal and journal lubricator.
The numeral 29 indicates a backing plate which is suitably mounted on the inner or rear portion of the protector 15, as for example as shown in FIGURE 4.
From the foregoing, it is apparent that there has been provided a grease well journal box dust guard which is an improvement over prior such devices such as that shown in prior Patent No. 2,497,864, and in use with the parts arranged as shown in the drawings, it will be seen that the protector 15 is adapted to be positioned in the slotted portion 14 of the journal box 13. The protector 15 includes the body member 17 which has the central opening 16 for the projection therethrough of a portion of the car axle 10. The protector 15 is provided with a pair of spaced apart chambers 18 which are shaped to snugly receive therein the containers 19, and the containers 19 are adapted to hold a quantity of oil 28 and these containers 19 may be pressurized so that when heating occurs, the plugs 27 will melt and the oil 28 will be sprayed out through the opening 26 of the spray nozzle 25 in order to prevent or minimize overheating. Each of the containers 19 includes the inner arcuate wall 22 so that with the parts arranged as for example as shown in FIGURES 2 and 3, it will be seen that these arcuate walls 22 will conform to the configuration of the opening 16 in order to snugly engage the portion of a car axle extending through the opening 16. The opening 26 in the spray nozzle 25 faces into the interior of the box 13 so that when these openings 26 are uncovered or exposed by melting of the alloy plug 27, the oil from the containers 19 will spray out through the opening 26 due to the fact that the oil is under pressure in the container as previously stated. The backing plate 29 helps maintain or retain the containers 19 in the chambers or recesses 18 as for example as shown in FIGURE 4. The con tainers fit in the chambers 18 with a snug fit so that accidental disengagement or movement of the containers from the chambers 18 will be prevented. Also, as shown in FIGURE 7 the lower portion of the wall 20 of the container is recessed inwardly as at 24 and a spray nozzle 25 is aflixed to this inwardly recessed portion 24 in such a manner that with the plug 27 over the opening 26, the plug will be flush with the wall surface 20.
The parts can be made of any suitable material and in different shapes or sizes.
As shown in the drawings, the oil containers 19 are recessed in the open pockets or chambers 18 and are not covered by any kind of plate on the journal side although there is a backing plate 29 on the wheel side, and the containers are held in place by a press fit. The alloy plug 27 is arranged in the recessed portion as shown in FIG- URE 7 so that this plug is flush with the face 20 of the container.
It will be seen that according to the present invention there has been provided an oil well journal box dust guard which will prevent or minimize the possibility of railway journal box overheating which is often referred to as hot box and it will be seen that there is incorporated into the usual journal box dust guard 15 two pressurized reserve oil containers 19 which are positioned or arranged so that they will spray a reserve of journal box oil on both the journal and journal lubri'cator. Initial heating serves to melt away the alloyed plugs 27 which cover the spray nozzles 25.
The present invention uses coolant oil rather than grease as set forth in prior Patent No. 2,497,864, and the coolant oil is indicated by the numeral 28. In addition the pressurized containers will afford a more positive liberation of the reserve oil as compared to the melting heat and gravity method utilized in prior Patent No. 2,497,864. The oil containers are positioned according to the present invention in a unique and desirable location so as to make the oil containers and their fusible plugs more sensitive to overheating.
Minor changes in shape, size and rearrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.
