SPRAY CONTROLLING DEVICE FOR ROAD SCAVENGERING MACHINES Filed July 9, 1928. 2 Sheets-Sheet 2 fly. 3.

Patented Dec. 17, 1929 Uhlt'lED STATES PATENT OFFICE This invention relates to a street scavengering machine. and consists in the combination with a spray-producer, and with meanswhereby the extent of the spray can be regulated transversely as well as longitudinally of the machine, and of a universally movable hand lever whereby said regulating means are con trolled for effecting a regulation of the spray in both directions.

Since in this arrangement there is only one operating lever, the regulation of the spray to meet varying road conditions will be greatly facilitated, particularly if the required movements of the lever are in accordance with natural promptings, for instance if the regulation of the spray is co-directional with the 1T10"-J(1I1G11t of the lever grip.

Fig. l of the accompanying drawings represents a sectional side view of one form 0f the device,

ig". 2, a front view of the same, Fig. 3, a sectional side view of a modified form of the device, and

Fig. i, a front view of the latter. In both constructions the spray-producer cons. ts of a cylinder awhichreceiveswater or other liquid from a conduit 7?. and which has a series of perforations 6 through which the liquid is discharged in a spray the extent of which, transversely and longitudinally of the machine, depends upon the arrangement of the perforations in the cylinder wall. This extent can be regulated by means of valve elements whereby more or less of the perforations may be closed.

In the arrangement of Figs. 1 and 2 there are two valve elements one of which is composed of a piston valve 0 arranged inside the cylinder and adapted for slidable adjustment therein. The other valve element consists of asleeve g which is adapted to be rotated about the cylinder and which has a cut-away portion it through which all the perforations b can be exposed when required, while the number of open perforations can be reduced at will by a rotary adjustment of the sleeve. A toothed rim 2' on the head of the sleeve 9 meshes with a toothed sector 70 which is secured to a shaft 0 carried, parallel with the cylinder at, in a bracket m on the conduit 71.

A fork j) at the outer end of the shaft 0 holds, one a pivot pin a hand lever r whereby the shaft 0 and sector 70 can be rocked for rotating the valve element g. The lever, which is free to rock independently about the pivot g in the longitudinal plane of the shaft 0, carries, near the fulcrum of the lever, a pivot pin .5: which is normally in alignment with the shaft 0. Loosely arranged on the pivot pin 5' is an arm 25 which is thus constrained to follow the rocking movements of the lever r in the direction AB (Fig. 1) while it is unaffected by the hand-lever when the latter is rocked in the direction CD (Fig. 2) for adjusting the valve g. The valve element 0 is controlled by a rod 7 which passes through a gland (Z and which is engaged by a fork a at the free end of the arm 6 so as to cause the valve to be adjusted when the two levers rock about the pivot q.

T he left side of Fig. 1 is turned towards the front end of the machine, and the lever 1' will therefore have to be turned rearwards for restricting the spray in the longitudinal direction, this being a natural movement. So is also the movement indicated. in Fig. .2 for restricting the extent of the spray from the side of the machine, the lever being for this purpose turned from its more or less vertical position towards the centre of the machine, i. e., in the direction in which the spray is to be r stricted.

In the arrangement shown in Figs. 3 and 4 the regulation of the spray is effected by means of a single valve element 0 which is adapted for rotary as well as slidable movement. The valve has an edge 1) whereby, on being rotated, it restricts the spray in a transverse direction, an edge w whereby, on being moved axially, it restricts the spray in the longitudinal direction. A red P which controls the valve, is fitted at its outer end with a crank 00 which is engaged by a fork a situated at one end of a double-armed hand-lever r which, like the lever r of the previous construction, is mounted on a pivot pin Q in a fork p at the end of a rotatable shaft 0.

When the hand lever is rocked in the directions CD (Fig. 4) it turns the valve 0 through the medium of the crank a2. VJ hen it is rocked in the directions AB (Fig. 3) it acts on the crank for displacing the valve in the longitudinal direction.

I claim:

1. In a street scavengering machine, the combination with a spray producer, and with means in said spray-producer for regulating the extent of the spray transversely as well as longitudinally of the machine, of a handlever capable of universal movementabout a fulcrum, and connection between said lever and the spray-regulating means for controlling the latter.

2. A structure as claimed in claim 1 wherein the arrangement is such that the regulation of'the spray is codirectional with the movement of the lever grip.

'3. In a street-scavengering machine, a spray-producer comprising a perforated cylinder, two valve elements cooperating with" said cylinder for closing the perforations, one of said valve elements being rotatable about and the other slidablerelative to the cylinder, a toothed sector controlling the l rotatable valve element, a shaft arranged parallel with thecylinder and carrying said sector, a hand-lever pivoted to said shaft so as to participate in the rotary movements of the.

latter and allow ofbeing rocked independently in the longitudinalplane of the shaft, a.

pivot pin carried by the hand-lever near its fulcrum and held normally in alignment with the shaft, a forked arm mounted loosely on said pivot pin, and a rod connected to the slidable valve elementand engaged by the fork of said arm so as'tocause said latter valve to be adjusted when the hand-lever is rocked.
