above to overcome this problem it has been found advantageous to provide the grease nipples themselves on housing 20 interconnecting the nipples with the lubrication points by means of high pressure flexible tubing with reference once again to fig1 and 2 a plurality of lubricant input means such as grease nipples 40 are arranged on cowling 24 adjacent the ends thereof the number of such nipples corresponding generally to the number of lubrication points on the vehicle flexible tubing such as high pressure nylon hoses 42 lead from each nipple 40 to a lubrication point and are connected to the lubrication point by means of 90 u00b0 adaptors 44 to this end existing nipples may be removed and the adaptors are threadedly inserted in their place to provide clearance for hoses 42 as they leave nipples 40 base plate 23 is recessed as at 22 if more nipples are required the length of housing 20 may be extended to accommodate for instance two rows of nipples at each end thereof alternatively the extra nipples may be affixed to an add on plate 50 such as is shown in fig3 illustrating another embodiment of the present apparatus as will be seen from fig3 plate 50 is formed having for instance three apertures not shown formed adjacent one edge thereof which fit over grease nipples 40 so that the plate may be connected to the housing by means of the same nuts 40n which fasten nipples 40 to cowling 24 additional grease nipples 40 are mounted onto plate 50 as required in fig3 like elements have been referenced by like reference numerals to those used in describing the embodiment of fig1 and 2.
