TAR HEATING AND SPRAYING APPARATUS COMBINED WITH STEAM ROAD ROLLERS.
Application filed October 1, 1927, Serial No. 223,420, and in Great Britain February 23, 1927.
rIhis invention relates to impro vements to apparatus used in combination with steam road rollers for heating tar or the like andk for distributing the same for road making purposes.
According to this invention, a tar tank located across the smoke boxr of the steam road roller and preferably partly within the said smoke box so th at the hot flue gases of the steam roller may be used to heat the tar. The tar tank may be provided with a acket around' it through which the hot fine gases pass.
In conjunction with the tar tank, means may be provided for distributing tar from the tank on to the road surface to be treated.
Other features of the invention will appear from the following description andv will be pointed out in the claims appended.
The invention will now be described by way of example with reference to the accompanying drawings `rwhereon Fig. l is an elevation of a steamv road roller having the tar heating tank combined theref with in accordance With the invention.
Fig. 2 is a plan View corresponding to Fig. l. K
Fig. 3 is a cross sectional elevation through the tar tank.
Fig. 4c is a view ofya tar tank showing a modification. y
Referring to the drawingszj Y In the example shown at Figsjl and 2 a steam road roller 1 is shown With a tar heating tank 2 located transversely across, and partly through the smoke box la of the steam road roller. The tank 2 is shown jacketed, by flues 2a leading the hot gases from the boiler smoke box la to the chimney lb of the steam road roller l.
The tar tank 2 lies acrossthe smoke box with a portion 2b of the bottom of the tank 2 and portions of the front and back of the tank Within the smoke box and exposed directly to the hot gases in the smoke box la, the remainder of the tank 2 being heated by the waste heat from the smoke box passing around the flues 2a which form an enclosing jacket for the remainder of the tank surface. By this arrangement the tar tank 2 is heated, or the heating of the tar tank is supplemented by the hot gases in the jacketing fines 2a which give a simple, economical and effective heat ing means. f
The fines 2a Which form the heating jacket pass to the chimney lb. A bye-pass flue 3 In addition to the waste heat for heating the tank as described, I provide (see Fig. l
heating means such as a steam coil 5 in the tank itself, live steam being supplied to this heating coil 5, from the boiler of the road roller and under suitable control.
Distribution of the tar or the like from the tar tank 2 is obtained by means of a pump G and a transverse distributing pipe 7 provided with spraying nozzles. The pump 6 is driven by chain gearing from the crank shaft lc of the steam road roller l. This pump 6 is also adapted to be used for filling up the tar tank 2 from a tar boiler or other receptacle brought to a convenient position near the steam road roller. Suitable pipes 8 and 8"l and connections from the pump 6 with the necessary valves 9 and 9 are provided to per-` mit of shutting of the connection between the pump 6 and the spraying pipe 7 when the tank is being filled. The filling connection 8a to the pump 6 is `capable of being closed by the valve 92L when the pump 6 is being used for spraying the tar from the tank. A rotary pump 6 is shown, but any other suitable pump, and any other suitable distribu tion and filling arrangement may be used as desired.
In the modification shown in Fig. 4t, pipes ver of means for heating tar comprising a tank for tar located across, and partly Within, the smoke box of the steam road roller, and a jacket around said tank through which jacket hot flue gases from heating v the boiler of 1the roller pass to heat the tar in said tan l 2.
