T 0 all whom. it may concern Be it known that I, TOM ABBOTT, a subject of the King of Great Britain and Ireland, residing at 30 Llantrisant Road, Pontyc-lun, Llantrisant, South Vales, have invented new and useful Improvements in Means for Mechanically Oiling the lVheels of Tramway and like Vehicles, of which the following is a specification.

The invention consists of improved means for mechanically oiling the wheels of the tramway vehicles that are used in mines and the wheels of other like vehicles.

The invention has been devised with the object of producing means, fulfilling the above referred to purpose, which can be used with vehicles that are provided with chambered hubs of ordinary construction, that is to say means which will not entail any particular construction of the parts of the hubs of the wheels of the vehicles. I

The improved means consist of pumps which are arranged at the two sides of a track for the vehicles and comprise fixed oil wells or tanks, pump cylinders which are supplied with oil from said wells or tanks, mounted thereon in such manner that they can swivel on fixed axes and are normally directed toward the vehicles to be oiled,

spring-controlled plungers which reciprocate in said cylinders and are provided at their front ends with nipples adapted to cooperate with the hubs of the vehicles, and means for returning said swivelling cylinders to their normal positions when the oilin of a pair of wheels has been effected.

he invention is illustrated by the accompanying drawings. H

.Fig. l is a part vertical section and partelevationillustrating the invention, the right half of the figure being in elevation and the left half thereof in. section.

Fig. 2 is a plan of the parts shown in Fig. 1.

Fig. 3 .is .an elevation of one of the oil wells or tanks and parts secured thereto, as seen from the outer side of the well or tank, the pump cylinder and piston being shown in mid-position.

Fig. 1 is a view. corresponding to Fig. 3,v

plungers of the oil pumps and a part of the chambered hub of the wheel of a vehicle, and F 1g. 6 is an end view of said plunger, drawn to the same scale as Fig. 5.

Referring now to these drawings, 1 are two of the wheels of a tramway vehicle such as 1s used in mines, and 2 are the chambered hubs of the wheels 1. 3 are rails for said wheels. 4 are housings that engage with screwed holes 5 formed in the outer walls of the chambered hubs 2 and are provided with projecting bosses 6 of hexagonal shape so that they may be. readily screwed into the holes 5. 7 are buttons which are constantly pressed by springs 8 against seatings 9 formed in the central parts of the outer walls of the chambered hubs 2, and 10 are passages formed in the housings 4 through which oil can be injected into the hubs 2. The above described construction ofchambered hub is one of those commonly employedon tramway vehicles used in mines and forms no part of the present invention.

11 are tanks or wells, hereinafter referred to as wells, which contain the oil to be used for oiling the vehicles and serve as supports for the rails 3. These wells 11, though they may form parts of a single casting, are preferably made separate from one another so that the same wells may be used with tracks of varying gauge, distance pieces of widths differing according to the gauges of the rails being interposed between the wells and bolt ed to the inner faces of the lower parts thereof. 12 are plates fixed to the upper parts of the wells 11, and 13 are cylinders which are mounted on the plates 12 in such manner that they can swivel on fixed axes. For this purpose the cylinders 13 may be formed with downwardly projecting bosses 14 and the plates 12 with holes 15 and the cylinders be secured in position by means of nuts 16 engaging with the lower parts of said bosses, ball bearings 17 and 18 being interposed between the cylinders 13 and the upper. surfaces of the plates 12 and between the uppermost of the nuts 16 and the lower faces of the plates 12. 19 are passages leading from the lower ends of the bosses 14 to the interiors of the cylinders 13, and 20 are dip tubes screwed into the bosses 1-1 and extending to a short distance from the bottoms of the wells 11. 21 and 22 are automatic valves fitted to the lower ends of the dip tubes 20 1 turned to their normal positions,

either by means of weights 32,

' weights as parts and to the upper ends of the passages 19. 23 are pluiigers fitting the front ends of the cylinders 13, and 24 are springs bearing at their ends against the rear ends of said plungers and the rear walls of the cylinders 13. 25 are screws which engage with the cylinders 13 and with grooves'26 formed in the plungers 23, and serve not only as a means for limiting the movement of the plungers but as a means for preventing same rotating in the cylinders 13. 27 are cavities formed in the plungers 23, and 28 are passages leading from the front ends of the cavities 27 to the front ends of the plungers 23. 29 are non-return valves fitted to the rear ends of the plungers 23. 30 are nipples at the front ends of the plungers 23, which are preferably formed separate from the plungers and screwed into same. The fronts of the plungers 23 are made of a shape appropriate to the particular constructions of the hubs of the vehiclesto be oiled. When said wheels are fitted with housings 4 provided with projecting bosses 6 the front ends of the plungers 23 may be made of the shape shown in section in Fig. 5 and in front elevation in Fig. 6, that is to say the front ends of the plungers may be formed with project-ions 31 of horseshoe shape. They may however be merely cupped or recessed at their centres, as shown in chain lines in Fig. 5. In either case the projecting parts at the front ends of the p-lungers 23, surrounding the nipples 30, serve. as guards for protecting the nipples when the plungers are swung back- Wards at the com 'letion of the oiling of a pair of wheels. he cylinders 13 are rewhen" displaced therefrom,

securedto wire ropes 33 which in their turn are attached to the cylinders, assshown in Figs. 2 and 3 or by means bf springs 34, as shown in Fig. 4, said normal positions being determined by stops 35. These stops 35 may be supported by or formed in one with castings 36 bolted to the top-s of mal positions by means of the weights 32 as supports for guide pulleys 37 for the ropes 33, and when springs are used in lieu of to which are attached the relatively fixed ends of said springs. "The stops 35 preferably consist of plungers slidably mounted in the castings 36 and controlled by somewhat stout springs, as this construction of stop enables the cylinders 13 and plungers 23 to yield when the vehicle is travelling in a backward direction.

Suitable means are provided for ensuring that the hubs 2 of the wheels 1 shall be in correct position when passing the oiling app aratus, a result which may be attained, see

i'gs. 1 and 2 of the drawings, by making the inner faces of the oil wells 11 of the necsprings 8 What I have invented the wells 11, said castings serving when the cylinders are returned totheir nor-i described above co-operate as Fig. 2. As the wheels of a vehicle travelling on the rails 3, in the direction of the arrow a, reach the outer ends of the plungers 23 the hexagonal parts 6 of the housings 4 will contact with the inner faces of the forward parts of the horseshoe shaped or like parts 31 surrounding the nipples 30, and the cylinders 13 will commence t0 swivel on their axes of rotation and the nipples 30 will come into contact with the buttons 7 which will be pressed backwards and compress the controlling same. When the springs 8 have fully compressed the plungers 23 will in their turn be pressed back,

the non-return valves 29 will be opened, and

oil will be injected into the hubs of the wheels until the cylinders 13 move into a position when their axes are at right angles to the rails 3. As the vehicle travels onwards the cylinders 13 will be swung still further on their axes of rotation and the plungers 23 will eventually become disengaged from the projecting parts 6 of the hubs of the wheels and be returned by the weights 32 or the springs 34 to their normal positions, in readiness to oil a fresh pair of wheels.

Although the improved means for mechanically oiling the wheels of vehicles have been described with reference to vehicle wheels which are provided with the particular construction of chambered hubs illustrated by the accompanying drawings the use of the invention is not necessarily confined to wheels fitted with this particular construction of hubs. j and desire to secure by Letters Patent of the United States is as follows 1. Means for mechanically oiling the wheels of tramway and like vehicles consisting of pumps arranged at the two sides of a track for the vehicles and comprising fixed oil wells, pump cylinders supplied with oil from said wells, mounted on said wells so as V to swivel on fixed axes and are normally directed toward the vehicles to be oiled, springcon'trolled plungers reciprocating in said cylinders and provided at their front'ends with nipples adapted to co-operate with the hubs of the wheels of the'vehicles,

cylinders, and means for returning said cylinders to their normal positions when the oiling of a pair of wheels has been effected, substantially as described.

2. ,Means for mechanically oiling the wheels of tramway and like vehicles constops for determining the normal positions of said sisting of fixed oil wells located one at each side of a track for the vehicles, plates closing the upper ends of said oil wells, pump cylinders mounted on said plates, formed with bosses having passages communicating with said cylinders, and secured in position by means of nuts engaging with said bosses, plungers fitting the front ends of said cylinders, formed with cavities and with passages leading from said cavities to the front ends of the plungers, and provided at their rear ends with non-return valves, nipples at the front ends of said plungers communicating with the passages leading from said cavities, dip tubes secured to the lower ends of the bosses formed on said cylinders, automatic valves fitted to the lower ends of said dip tubes and to the upper ends of the passages formed in the bosses of said cylinders, means for returning said cylinders to their normal positions when displaced therefrom, and stops for determining the normal positions of said cylinders, substantially as described.

In testimony whereof I have signed my name to this specification.

TOM ABBOTT.
