OILING DEVICE FOR ROAD ROLLER-S.

Application filed January 18, 1922.

To (4Z5 whom it may cone-em:

13c it l-cnown that l, Dininn S. hloNRon, a citizen of the United ,dtates, residing at Portland. in the county of li lultnomah and Fttate of Uregron, have invented a new and useful improvement in (Filing Devices for Ro d Boilers, of which the following is a specification.

This invention relates to road rollers, and is more particularly directed to an oiling device for oiling the surfaces of the pressure rollers or" a road roller,

in object of this; invention is the provision of a new and improved oiling means 1 for spraying oil on the front and rear pres sure rollers by means of an ejector operated by the steam from the engine which drives the road roller, and which is controlled by the engineer from his position on the road roller. whereloy it is unnecessary for him to subject himself to possibility of danger by being compelled to work among the inovparts of. the road roller in. order to ad just the flow of oil.

The invention will be best understood cm a consider ion of the following detailed description taken in connection with the acc-oinpa. 1g drawing forming part of this specification. with the understanding, howeveu that the invention is not confined to any strict con orn'iity with the showing in the drawing, but may be changed and modified so lone: as such channes and modifications nu" no material departure from the salient features of the invention as expre 7 d in the appended claims.

in the drawinp3:--

Fig. 1 is a side elevation of road roller disclosing; my oil spraying device in operative relation to the pressure rollers.

Fig. 2 is a plan view of the same with parts removed. disclosing; the spraying device in o 'iera-tive relation to the pressure rollers.

Fig: 3 is a lon ritudinal section of the ejector.

Fig. 4- is a detail view in section of one of the nozzles of the spraviup,- devices,

Generally speaking, the oil spraying de vice comprises a source of oil, an ejector connected with the source of oil, conduits connecting the ejector with the steam encine, discharge pipes connecting the ejector with spraying; devices associated with the front and rear pressure rollers, and valves Serial No. 530,212.

for controlling the flow of steam and oil through their respective conduits.

Referring; more particularly to the drawing, 1 designates a steam engine with its boiler carried by the front pressure rollers 2, and the rear pressure rollers 3 and 4:. A controlling means 5 for guiding the front pressure rollers 2 is adapted to direct the movement of the road roller. These elements are old in the art and form 110 part of the present invention.

Fiupported in baskets 6 are oil containers or reservoirs 7 and 8, located upon opposite sides of the engine and boiler l. Plugs 9 close an opening in the top of the containers 7 and 8 and provide means by which oil may be supplied to the containers. The container or reservoir 7 is provided with a connection 10 for a conduit 11. A check valve 12 is mounted in the conduit 11 and permits oil to flow from the container through said pipe, but wi l prevent the oil or other fluid from re-entering the reservoir 7. A stop cook 13 is likewise mounted in the pipe 1]. and is provided with a handle let for operating the valve. An operating rod. 15 extending; rearwardly of the road roller is mounted near its outer end in a bracket 16 and provided with handles 17 adapted to be gripped by the engineer, whereby the stop cock 13 may be operated from the seat of the engineer.

A vertical pipe 18 is connected at its lower end to the pipe 11 and at its upper end to an ejector 19.

The ejector 19 as shown in 3 comprises a steam nozzle 20 seated in one end of the casino: 2i of the ejector, and is held in place by means of a nipple 22, engaged by the annular flange of a union 28, having screw-threaded engagement with the externally threaded outer end of the casing 21. lln the other end of the casing); 21 is screw threaded an ejector tube 2e provided With external tl'ireads engaging the internal threads in the forward end of the casing 21. llhe ejector tube 24-. is of a larger diameter than the steam nozzle 20, but of smaller diameter than the pipe 18.

The nipple 22 is externally threaded and screwed into the internally threaded end of a steamy conduit which extends rearwardlv of the road roller, and is connected to the steam chest of the engine at 26, Fig. 2. A globe valve 27 is located in the steam 28 is provided roller and paralle=.

' the oil from pipe for controlling the flow of steam from the engine to he ejector 19, A. handle for ogmrating the valve 27.

Connected to the forward end of the casing 21 of the ejector a short pipe 29 3) which is connected by an elbow 30 to a vertical discharge pipe 31. The vertical discharge pipe is provided with a check valve 32 (Fig. 1) r This valve is only useful when it sired to supply the sprayer with water. i in pipe 31 is connected by a T-coupling 34- to the forward and rearward discharge pipes 35 and 36, respectively. The dischai pipe 35 extends downwardly and is connected to a horizontal discharge pipe 39 (Fig. A support 38 secured to the boiler l and to the T-couplinp; 34 maintains the discharge pipes 35 and 86 in position. The discharge pipe 39 is p'rovided with a check valve 40 which permits fluid. to pass forwardly and out of the pipe 39 to the T-connection ll, but prevents fluid from returning' to said pipe. A flexible tubing 42 provides a connection between the T-connection ll and the trout spraying device 43, which is adapted to spray oil onto the front pressure rollers 2.

The rearwardly-extending discharge pipe 36 is provided with a valve operated a handle to cut oil communication be tween the ejector l9 device l6, associated roller 3.

The handle 45 may be connected by means of an operating rod similar to the rod 15 and directed rearwardly to a pointnear the seat of the engineer, whereby the valve 44 may be controlled remotely from its position on the pipe 46. This obviates the necessity of the engineer working among the moving parts of the road roller when he dd sires to regulate the oiling device.

As shown in Fig. 2, the parts scribed comprising the ejector, the voir and the several discharge conduits leading to the front. and rear of the road roller,.are duplicated on the other side or" the road roller.

An ejector 45? similar to the ejector 19. connects d to the steam engine by means ot a conduit 48 running rear-war of the road to the steam conduit the flow of steam being controlled by a valve 49 operated by a handle 50. p

A stop Cock 51 which controls the How of": the reservoir 8 to the ejector 47, is provided with a lever 52 connected to an. ope at-lug rod running re iwrardly. The rod 58 has a handle 17 similarly loand the rear spraying;

with the rear pressure u st (lo-- oil resenc-ate-d near the seat of the engineer as is the handle 17 for the rod 15. The eject r l? is connected by a rearwardly-extendinn discharge pipe 54 to a spraying device 55 associated with the rear pressure roller A forwardly and downwardly extending; discharge pipe 5? to permit oil to low to the llc :iblo tubing 19. hut prevent oil from the discharge pipe 3.) from flowing; luu-ltvrurdlv into the pipe 57.

checl: valve 5!) similar to the chm-l: valve 12 is employed in the liscluu'g'o (ouduit leading: directly from the oil revcrvoir 8 to prevent luid from entering): the reservoir when steam under an excess ve amount of pressure tends to a t rcamvardlv in the discharge conduits located between the l'(. (l' voir 8 and the ejector 4?.

A manually controlled valve (30 similar to valve- -l:-fl is located in the discharge conduit 54. and operated by a lover (l l for cuttiupj oll comnmnication between the roar spra 'imr device 55 associated with he rczu pressure roller 4 and the ejector l7.

Each of the suuill perforations lo'ulcd iu the Sl)l& 'il1]1 devices 4c and 55 is pro vided with a nipple (52. upon which is mounted a short length of rubber tubing (l3 oi? substantially the same diameter as the nipple 62 but longer than said nipple. The portion of the tubing which extends hcyoiul the nipple provides a means For directing the oil from the several spraying devices onto the respective pressure rollers. Fur thermore, it may be stated thu by this construction oil is forced directly from the spraying: devices onto the wheels; oi the pres-- sure rollers. d the oil is thus protected from strongwinds which would [cud to blow the oil away 'l'roui the rollers (Fi i. 4-).

.ln otwrat o i. the tanks i and al'c lillv-d with oil for luhricatiuc' the rims o l' the pres sure rolle s 2?. I) and 4 to pr v u. the hot. dressing oi" the roalbcd from adhcriu -i to rid rims As long; as the pressure lnllr'l's are traveling over the surta. r of the troshlv treated roadbcd. it is ucccssai v that said rollers be constantly sprayed with oil. Since the sprayingdevices 41 lt' and 57 are in constrnt operation. a considerable :uuouut of oil must be su 'u'ilied to them. and there-- fore tanlt having? a capacity ot at least six gallons each is desirable. The clinch valve-e l2 and 5.) pcru'iit oil to tlow lhrou rh the containers 7 and 8. respectively. but prevent any liquid from returning to said reservoirs or containers.

Rods 15 and 5 -3. respectively. operate the respective stop cocks l3 and :il. whereby the amount of oil flowing from the reservoirs T and 8 is regulated and since those rods ex tend to the rear ol' the power plant and near ill! llfl

the engineers seat, they may be controlled from that position without it being necesthe rear pressure roller 3, when the valve 27 has been opened to admit steam from the boiler 1 to the pipe 25.

When the stop cook 51 is opened, oil will he admitted to theejector 457, and then forced through the discharge pipes 5 1 and 56 by men: of steam from the pipe 48 when the val e a9 is opened to admit steam trom the boiler 1 to the pipe 48. Oil is thus iorced along the dischargepipes 5 and 56, respectively, to the rear spraying device 55 associated with the pressure roller 4: and to the forward spraying device 43 associated with the trout pressure rollers It will be seen that oil is lied to the trout spraying device 4:3 by both ejectors 19 and t7, while the respective ejector-s 19 and 4t? supply independently the rear spraying devices 4-6 and 55.

It will be unnecessary always to supply one of the two pressure rollers 3 and 4; with oil, since it frequently happens that onlyv one of these pressure rollers. is in operat ve position tor rolling the newly treated. roadhed. Therefore, valve in. may he. closed to out out connnunication between the ejector 19 and the spraying device 46, when the operating handle of the valve 44 is manipulated. Valve 60 may be operated to cut oft communication hetween the ejector 4-7 and the spraying device associated with the rear iiressure roller 4.

it will he seen that by closing; the valves 44; and (it), either one of the spraying de vices or may he cut ot'i troni the supply of oil, but at no time will the front spraying device 43 he cut oil from the ejector-s 19 and 4-7, since the front pressure rollers 2 will. always he employed in rolling the roadhed when the road roller is in operation. 7

The check valves 40 and 58 are supplied to the discharge conduits 39 and 57, respectively, to prevent oil discharged by either ejector 19 or a7. from passing from one side of the road roller to theother, and entering either one of the discharge pipes, when either valve 44 or cuts o'l'l communication between the respective spraying devices 46 and as for example. when the rear spraying device 46 is cut out oi communication with. the ejertor 19. greater pressure will he exerted upon the oil delivered to the discharge conduit 39 and to the front spraying device 43. In this case,

there will he a tendency to force .oil not only into the spraying device 13, but also into the discharge conduit and towards the ejector t7, and along the discharge conduit 54 to the rear spraying device 55, associated with the rear pressure roller 4. in this case there would he a tendency to supply more oil to the rear spraying devh e 55 than is necessary, hut the check valve which permits oil to tlow from the discharge conduit 5? to the front spraying device 43, will prevent oil from the dischar conduit 39 from entering the discha conduit 57.

The same conditions will rise for supplying a greater quantity of oil to the sprayer 16 when the rear spraying device 55 is cut oil "from comn'iunication with the ejector 4L7, and when the rear spraying do vice d6 is in communication with. the injector 19. The check valve 4:0 will prevented in the discharge conduit 5" trom entering the discl'iargo conduit 39 and the discharge conduit 36 to the other rear spraying device 46' associated with the pressure roller 3.

The tiexihle pipe 42 is used to connect the T-connection 41 with the frontspraying device 43, and as such permits the front pressure rollers 2 to he turned on their axes when the pressure rollers are operated to guide the road rollers by the controlling means 5. i 1

l l hilc lhave shown the oiling device applied to a three wheel road roller, nevertheless it may be equally well aplied to the smaller or tandem rollers which are used in the city. In such case, but one oil reservoir and one ejector will be employed, in cooperation with a single sprayingdevice for each pressure roller similar to the front spraying device 4:? shown in 2. This construction has not been disclosed since it is thought unnecessary to illustrate the numerous "forms to which the spraying device may he applied. l lo new problem. is involved in applying the oil spraying system to the different torms of road rollers. sin e the principle employed for spraying the pressure rollers and the manner of controlling the spray will he the same.
