BEARrNGlBox roR MINE CARS.

Application ledseptember 15, 1921. Serial No. 501,009.

To all whom t may concern:

Be it known that I, WILLIAM R. MHLER, a citizen of the United States, residing at Park Place, in the county of Schuylkill and' State of Pennsylvania, have invented certain new and useful Improvements 1n Bearing Boxes for Mine Cars; and I do declare the following to be a full, clear, and exact 'de-4 scription of the invention, such as will en-y able others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved bearing box for use in connection with mine cars and one object of the invention is to provide a bearing box so constructed `that it may be mounted upon a longitudinally ex.- tending under-beamof the mining car without it being necessary to pass bolts up through the bottom of the car. At the present time, it is customary to secure the bearing boxes by means of bolts which pass u through the bottom of the. car and throug the'sheet metal body portion of the car. When it is necessary to renew the ysheet metal body portion, it is then necessary to form holes in the sheet'metal so that the securing bolts may pass through theml and it has been found to be exceedingly V'difficult to properly placethese holes. By'means of the improved bearing box disclosed in the ac companying drawing, the bolts may pass transversely through the under-beam of the car and therefore the sheet metal body portion of the car can be renewed'without'it being necessary to remove the securing bolts for the bearing boxes. 4

Another object of the invention is lto provide a bearing box in which the end portions of the brass bearing block will lextend through the side portions of the box or housing where they may be readily :seen and danger of their not being removed at the proper time avoided. Another object of the invention is to provide improved means for `holding the brass bearing block against movement longitudinally of theaxle and against rotary move-I ment about the axle.

Another object of the invention is to provide an improved type of bearing box having the box or housing proper positioned beneath a supporting bar with which the end portions of the lbox or housing are removably and pivotally connected, the box lor housing being so constructed that no special care is necessary in putting the box or housingin place.

Another object of the invention is to provide the box or housing with an improved construction -providing pockets or compartments 1n which lubricant applying brushes may be placed, a brush being only placed in' one compartment and this brush applying the lubricant to the side portions of the axle.

p Another object of the linvention is to soV constructv the supporting barvand housing that the lubricating'oil may befed through a passage formed in the supporting bar and drop down onto a partition above the brush, the partition being provided with a groove sothatthe oil will be fed onto the brush and absorbed by this brush. v Another object of the invention is to yprovide a bearingbox which can be readily applied to lacar body and which will be securely held in operative position but may be very readily taken apart for cleaning or repair purposes and very easily and quickly put together. y

. This invention is illustrated in the accompanying drawings, wherein:

.Figure l is a view in side elevation showing the improved bearing in position for use.

Figure 2 is a view in side elevation showing 'the structure of Fig. l but looking at the inner side thereof instead of the outer side.4 lFigure 3 isa longitudinal sectionalview through the structure of Figs. l and 2.

Figure 4 is Ia transverse sectional `view takenA along` the line 4--4 of Fig. 1.'

Figure is a` transverse sectional view taken along the line 5--5 of Fig. l. f

Figure 6 is a transverse sectional view taken along the line 6 6 of Fig. 3; y Figure 7 is a perspective view of the supportingbar which is secured upon the underbeam of the oar body.

` Figure 8 is a perspectveview of the brass bearing block. Figure 9 is a perspective view of the box orfhousing carried by the supporting bar.

Figure l0 Vis v4a perspective view of the spring which holds-the brush lin proper engagement with the axle. n y This improved Vbearing is for use in connection with a mine car having a body portion'indicated in general by the numeral l and having at each side a longitudinally extending underbeam 2.V The axles which means ot the improved bearing boxes, it

being understood that one ot the bearing boxes will be provided t'or each end portion of the axle.

This bearing is provided Lwitlra supporting bar 3 which is U-shaped in cross scction or end elevationas shown in Figs. le and 5 and has its side walls l extending up along the sides of the underbeam 2. Securing bolts 5 are passed through the walls Il and underbeain 2 and will thus serve to se'- curely but releasably hold the supporting bar in place From an inspection otFig-s. 4f and it will be readily seen that the bear ings may be easily removed without disturbing the sheetmetal body portion ot the car and also that the sheet metal body portion ot' the car may bereplaced without thebearings beingV disturbed.

W'hen a. coal car'is in use, it isf customary to shift the same outV of a horizontal position so that the coal may readily pass out of the car and this would place undue strain upon the bolt side which extends transverselfy" through the underbeam 2. Therefore, the supporting bar 3 has-been provided' with a transversely extendingv rib 6 whichis rectangular in cross section as shown in Fig. 3 and is positioned in a correspondingly shaped groove 7 :tormed'inthe underbeam. rlhe supporting bar will thus be held against movement longitudinally of the underbeam and strain willv be removed from the securing bolts.

The brass bearing bloclrS which is shown in perspective in Fig. 8 isplacedb'eneat-h' the supporting bar and will rest upon the'axle 9 as shown in Fig. 3. This b'earinglblock 8 is positioned between the stripsV 10' which extend transversely ot the supporting bar and these strips 10 are provided with finger extensions 11 which lit into the recesses 12 tormedin the V bearing block. It willthu's be seenthat the bearing blocks will be securely held against movement longitudinally of the axle and will also b'e held a-gainst'any tendency to turn with the axle; One end ot the bearing block is engaged by a depend- Y ing flange 13 which extends from the inner side of the support-ing bar. This flange 13 serves not only to assist. in holding` the block against longitudinal' movement but also serves as a guard to prevent dust and tine coal from working into the bearings through the inner ends thereof.v The outer side port-ion of this supporting bar iscut as shown at 14e thus permitting the wheels' 15 to rotate freely without any chance of binding. ln order to strengthen the supporting bar and prevent it from being weakened by this cutout7 there has been provided a.Y strip 16 which extends in the corner portion thereof.

rThe housing 17 which is known asthe box is provided with end walls positioned between the side walls. These side walls are provided'. with cutouts 18" to receive the axles and permit the ends of the brass bearing blocks to extend through these inner and outer sides` of the housing or box. lt will thus be seen that these ends ot the brass bearing blocks can be readily seen and easily inspected to ascertain whether or not they have worn a sutiieient amount to need renewing. inwardly extending sleeves 19 exf tend from the upper corner portions of the side walls and above the upper edges of' the endjvallof the housing and will lit against opposite ends of the sleeves 20 which extend downwardly from the supporting bar 3; It will thus be seen that when the securing pins 21 are put in place, the housing will be ses eurely held inv an operative position but that when desired one oi' the securing pins mayl be removed'and the housing swung downwardly to an inoperative or open position.

In order to provide compartments in the housing tor carrying a lubricant applying brush, there has been provided partitions and 23; The space betweenI the partitions'22 andA 23 Yform the pockets 24 with the partitions 22 i'orming the lower walls ot the pockets or compartments and the partitions' 23 forming the upper walls ot the compartments. These upper walls will each be provided with grooves 24 which are so located that the housing may be put in4 place with either side outermost andl one. of the. grooves 2i will be` positioned beneath" an oil passage 25 formedU in the outer side pore" tion of the supportingbar. Vhen oilL is fed through` the passage' 25, it will drop down. into the groove .24"beneath `it or upon the upper partition 23 adjacent this groove and will pass through the groove and down" onto the' applying brushA 261 positioned in this' poeletor compartment. While two'of these pocketsor compartments are provided, there will be only one brush provided as it is only necessary' to apply oil toene side ofif'the axle. The two pockets are provided for cons venience in applying the housing. The brush 26 is formed Jfrom layers offelt which will readily. absorb the oil andthese. layers are securely connected in any desiredniain ner so that-a good brush will be provided: ln order to hold the brush in proper engage ment with the axle, there has been provided a strip 27 which is placed in the pocketor compartment before the brush is put in place. A spring strip 28 is secured to this strip 27 and will serve to move the strip 27 outwardly land thus apply pressure tof the brush to'torce it outwardly andph'old the brush in proper engagement vwith the axle;

When thebearingis in use, it will'be assembled as shown and the bearincr block 8 will rest upon the axle. As the axzlerotates with the wheels, the oil will'be applied? toit-he axle and thus the axle will be kept very'well Sii lubricated. sWhen it is necessary to replenish the oil, it is simply necessary to feed this oil through the oil passage 25. The brush can thus be thoroughly soaked with oil and further a surplus supply of oil may be supplied by pouring in enough oil to lill the compartment in which the brush is placed. When it is necessary to replace the brush or when it is desired to clean the housing or brush, one o f the pins 21 can be removed and the housing swung downwardly. The cleaning can then be performed and if desired a new brush put in place and the housing then swung upwardly to the operative position and secured. hen it is desired to remove the brass bearing block or bushing block as it may be called, the car can be jacked up afte'r the housing has been released and swung downwardly to the inoperative position. This will move the strips and nger extensions out of engagement with the bushing block and the block can then be removed and a new one. put in place. The car can then be lowered and when the block 8 is in the proper position, the housing can be again swung upwardly to the operative position and secured. It will be further noted that if desired, the body portion of the car can be raised after the bolts 5 have been removed and the wheels, axles and bearings removed bodily from the car.

I claim:

l. A n axle mounting comprising a support, a housing having its end portions pivotally and removably connected with said support whereby either end of said housing may be released and swung downwardly to an inoperative position, said housing having end walls recessed to receive an axle, and upper and lower partitions in the side portions of said housing forming brush-receiving pockets extending longitudinally in the side portions of the housing and intermediate the height thereof and between the end walls thereof.

2. The structure of claim4 l having each upper partition provided with an oil conducting groove leading to its edge, the supportl being provided with an oil passage whereby oil may be fed through the passage into the housing above the upper partition and after falling upon the upper partition passed through the groove into the brushreceiving pockets.

In testimony whereof. I have hereunto setl my hand.
