United States Patent 3,027,974 CARRIER DEVICES Gordon Davis Allen, Chalfont St. Peter, England, assignor to Allen Tool & Engineering Limited, Chiswick, London, England Filed Oct. 21, 1959, Ser. No. 847,810 Claims priority, application Great Britain Oct. 23, 1958 10 Claims. (Cl. 184-99) This invention is concerned with improvements in or relating to carrier devices and in particular to a spring loaded holder used in conjunction with a solid lubricating rod.
In the lubrication of moving parts of vehicles and machines it has been proposed to use solid lubricating rods which are of generally circular or square section and may be composed of a graphite mixture encased in a harder carbon tube or of molybdenum disulphide in a synthetic plastic carrier. Such rods are carried in a spring loaded holder and are held by spring pressure in contact with that part of the vehicle or machine to be lubricated.
It is desirable that the spring pressure be maintained relatively constant so that the rod may be used economically, and it is an object of the present invention to provide a spring loaded holder which achieves this desirable result.
According to the present invention there is provided a holder comprising a guide member slidably carried by a support member, means for releasably locking the guide member in a first position relative to the support member against the action of means biasing the guide member from its locked position, and a carrier supported by the guide member releasably locked with respect thereto and biased relative to the guide member in the same sense as the bias of the guide member relative to the support member, the means locking the carrier and guide member co-operating with means carried by the support member to unlock the carrier from the guide member upon the guide member reaching a second position relative to the support member.
In order that the present invention may be well understood there will now be described one embodiment thereof, given by way of example only, reference being had to the drawings accompanying the provisional specification in which,
FIGURE 1 is a plan view of a spring loaded holder in a fully retracted position;
FIGURE 12 is a section view along the line II=II of FIGURE 1;
FIGURE 3 is a section view through the holder shown in FIGURES 1 and 2 but in a normal position;
FIGURE 4 is an enlarged section view along the line IVIV of FIGURE 1 and,
FIGURE is a plan view of a pusher tube of the holder shown in the preceding figures.
Referring to FIGURES 1 to 3 there is shown a base 1, bearing mountings 2 and 3 spaced apart along the base and integral therewith, a guide sleeve 4 slidably and rotatably mounted in the bearing mounting 3, and a pusher tube 5 slidably mounted in the guide sleeve 4.
Referring now to FIGURES 2 to 5, the pusher tube 5 is shown to be a cylinder open at one end. A compression spring 6 is provided within the cylinder and is contained therein by a closure plug 7 secured by suitable means to the guide sleeve 4. These means, not shown in the drawings, comprise a threaded end of two diametrically opposed rods 8, each threaded end passing through a hole in the guide sleeve 4 and screwed into the closure plug 7.
Two diametrically opposed lugs 9 are rigidly secured to the periphery of the bearing mounting 2. Tension springs 10 are attached to the lugs 9 and the rods 8 as ICC shown in FIGURE 1, the springs lying approximately parallel to each other.
Slots -11, 12 and 13, shown in FIGURE 5, in the cylindrical wall of the pusher tube 5 define a resilient tongue 14. The tongue is provided with a detent 15 comprising a boss 16 and a smaller boss 17 partly bevelled at 18. A threaded hole '19 is provided in the cylindrical wall of the pusher tube 5 approximately diametrically opposite the boss 17.
The guide sleeve 4 is of cylindrical form. The wall of the cylinder is provided with diametrically opposed slots 20 and 2 1, one end of the slot 20 opening into an aperture 22.
The pusher tube 5 is located within the guide sleeve 4 by a screw 23 threaded into the threaded hole 19 and either the boss 17 engaging in the slot 20 or the boss 16 engaging in the aperture 22.
The holder is moved to the loading position in two stages. Firstly the guide sleeve is retracted to the position shown in FIGURES 1 and 2 in which position a lug 24 shown in FIGURE 4 integral with the guide sleeve 4 will register with a recess 25 in the base -1. The sleeve is then angularly rotated so that a part 24a of the lug 24 is contained within the recess 25 whence the sleeve is locked with respect to the base.
Retraction of the guide sleeve causes the end 20a of the slot 20 to butt against the boss 17 of the pusher tube 5 and so move the tube to a position intermediate that shown in FIGURES 2 and 3.
The second stage is to force the pusher tube 5 away from the bearing mounting 2 against the pressure of the spring 6 until the boss 16 of the detent 15 is positioned in line with the aperture 22 of the guide sleeve 4. In that position the resilient tongue 14 will tend to a normal position and in so doing register the boss 16 within the aperture 22 whence the pusher tube 5 is locked with respect to the guide sleeve 4.
The holder may then be loaded with a solid lubricating rod by placing the rod between the bearing mountings 2 and 3 so that one end of the rod seats in a seating recess 26 of the pusher tube 5, and the other end is in line with the bore 27 of the bearing mounting 2.
In order to hold the lubricating rod against that part to be lubricated the guide sleeve 4 is angularly rotated to the position shown in FIGURE 4 whence the sleeve is free to move forward under the action of the springs 10 until the rods 8 butt against the bearing mounting 3. When the lubricating rod has worn so that the bevelled part 18 of the detent 15 engages an edge 28 of the bearing mounting 3 the resilient tongue is depressed and the boss 16 moved out of engagement with the aperture 22. The pusher tube 5 is then free to move forward until the recessed end 26 thereof butts against the bearing mounting 3.
The carrier may be secured to the vehicle or machine to be lubricated in any suitable manner. In the embodiment shown the base 1 may be bolted to the vehicle or machine, the bolts passing through holes 29 in the base 1.
It can be seen from the foregoing description that the spring loading on the lubricating rod is double acting. Firstly the tension springs 10 provide the load and secondly the compression spring 6. This double acting spring loading gives a relatively constant loading on the lubricating rod and in so doing makes full economic use thereof.
