MACHINE FOR manure AND VSANYDING 'rI E summer: OF smears- To all 'uihom it may concern:

Be it known that I, WILLIA CHARLEs SOUTHGATE, a subject of Great Britain, re-- siding at Dunedin, New Zealand, have invented new and useful Improvementsin Machines for Tarring and Sandin the Surface of Streets and the Like, of which the fol! I lowing is a specification.

. The top of the tar tank :(2) is providedwith behind the tar tank [(2) is mounted a sand through the pipes (4).

My mventlon Is for a machine for tarring .and sanding the surface of streets. and, the

like, and is illustrated in the accompanying drawings, in which the same numerals of reference indicate similar parts, and Figure 1 is a sectional side elevation of the machine. Fig. 2 is a cross-sectional view illustrating the tar distributing means. Figs. 3 ahd 4 are cross-sectional views illustrating the brush and brush. cranks. According to my invention there is a four wheeled truck frame (1) adapted to be drawn by suitable motive power. About midway of the truck (1) is mounted 'a' tank (2)for containing the tar, the sides of the tank sloping towards acentral outlet fitted with a va ve (7) so that the tar may run out'readily even when the machine is on an incline.

a funnel (3) for filling .purposes. ,A series of vertical pipes (4) areconnected at their upper ends to the outlet valve (7) of. the tar tank (2) and at their lower ends. to a horizontal pipe (5) which extends transversely of the machine the desired width ashort distance above the ground, and which has its under surface perforated with a inumber of holes to allow of the exit of the tar (6), which flows from the tar tank .(2) down The valve (7) controlling the flow of the tar from the :tank (2) is 0 erated by'a connectingrod (8) and.-

han lever (9) mounted convenient to the drivers'"'seat (10). At the rear, of the truck,

hopper (11), the bottom of which is fitted with a'flap door (12) tpivoted at its-upper end, and normallyhel closedby a cord or chain (13) which passes over a (16) and is connected at one fen to the flap door (12) and at the other-end to a drum (14) fixed on the spindle of a hand'wheel- (15) mounted on the machine near the drivers seat (10). By the operation of the hand-wheel (15) the flap (12) may thus be kept closed or allowed to fall open under the weight-of the sand to permit the latter to flow out. A spreading roller (17) provided Specification of Letters Patent. Application flied October 10, 1907. Serial No. 396,836.

with a number of parallel rows of teeth (18) is mounted between the cheeks of a trough (19) fitted below the sand hopper (11) so that sand flowing from the hopper falls onto the-spreading roller (17) the teeth (18) of which are arranged with spaces between them,. and so thatthe teeth of one row are behind-the spaces between the teeth in the previous row. The back of the trough.(19)

working parts under the machine.

The spreading roller (17 is driven at a high speed by means of chains (20) which ass round small sprocket wheels (21) on the spindle (34) of the 8 reading roller (17 and larger sprocket whee s (22) on a spindle (33) mounted in a bracket secured under the frame of the machine. The sprocket wheels (22) are driven by means of fixed on the spindle (33) and caring with pinions (24) fixed on the rear ax e (35) of the road. wheels (25). Below the truck frame and behind the tar delivery ipe (5) is a reciprocating brush (26) norma ly touching the street surface and extending across the machine from end to end of the horizontal tar delivery I pipe (5). The brush frame (29) carries at its ends blocks (27) and is secured to sliding rods (38) which slide in guides (39) and are reciprocated by connecting rods (30) connected to cranks (31) on a sprocket wheel (36) mounted in a bracket secured under the truck frame. The blocks (27) slide in uides (28) see Fig. 3. The sprocket wheel 36) is driven by a chain (32) from a sprocket wheel (37) on the rear axle The brush is removably secured to the frame (29) so that when the machine is out of operation the brush may be removed. 1

In 0 eration, the tank (2) having been filled with tar, andthe hopper (1 1) .with sand, the'ha-ulage power is app i chine along, and the valve (7) is opened to allow the desired quantity of tar to flow be treated. e revolving of the rear wheels of themachine sets in action'the gearing beas to spread the tar on the surface, and also to revolve the spreading roller (17 The out, the sand falls on to the spreading roller (17 and is thrown out behind the machine brush. g

pinions (23) through the pi es (4) (5) on to the surface to 7 over the tar that has been-spread by theprevents any sand being thrown into the ed to draw the mafore mentioned to operate the brush-(26)-so i flap door (12)'ha ving been allowed to open-so that the desired quantity of sand can flow.
