LIQUID-HYDROCARBON DISTRIBUTER FR ROADS.

Specification of Letters Patent.

Patented J une A, 1912.

Application led January 19, 1911. Serial No. 603,543.

To all whom t may concern.'

Be it known that we, DAVID SoHoENrAG and ELMER J. LArUs, citizens of the United States, and residents of Glasco, Ulster county, State of New York, and Albany, county of Albany, State of New York, respectively, have invented cert-ain new and useful improvements in Liquid-Hydrocarbon Distributers for Roads, of which the following is a specification.

This invention relates to a device for spreading liquid-asphalt over crushed stone beds in road building as well as for distributing oil on top of the finished road to bind the tine surface together.

Une of the objects of the invention is the production of a simple, low-cost oneman device which may be used by unskilled labor during any part of the year.

A further object is to provide a dischargechamber of improved const-ruct-ion disposed transversely immediately below the storage and supply-tank, by means of which improved distribution is effected, the path aifected extending at both sides beyond the supporting wheels, together with novel means for regulating the discharge from the discharge-chamber, either uniformly or differentially throughout the discharge passage.

A further object is to provide means for causing the materialA entering the dischargechamber to be distributed substantially uniformly throughout the length thereof.

A still further object is to provide the discharge-chamber with a vent conducing to the free and uniform flow of the fluid.

ln the drawings hereto annexed Figure 1 is a plan view ofthe invention, with partsV broken away and insection; Fig. 2 is a vertically longitudinal sectional elevation, on line 2.*2, of Fig. 1; Fig. 3 is a rear end view; Fig. t is a view ofthe front and underside of the discharge-chamber looking in the direction of the arrow A of Fig. 2; and Fig. 5 is a view of the same part-s looking at right angles to Fig. A.

The device comprises an oblong storage and supply-tank 10 supportedV by a pair of wheels 11, which are mounted on the ends of a rod or axle 12 passing through a transverse tube 13, the latter being secured to the side walls of the tank and constituting in effect a brace therefor. The ends of the said tube 13 extend beyond the tank and form end thrust bearings for the hubs of .the wheels 11, and the tube and rod aord a strong axle-support for the wheels as well as a brace for the tank while obviating any danger of leakage at this region. A pair of shafts 1A secured to the tank and extending forwardly therefrom constitute means whereby the operator may draw the cart-like device. Beneath the rear end of the said tank 10 is a transverse dischargechamber 15, the latter having its ends extended beyond the sides of the tank and beyond the outer lines of the wheels so that the latter need not travel on a previously v oiled strip or path. The discharge-chamber 15 has a rear wall 16 which is preferably vertical and a front wall 17 which inclines downwardly and rearwardly toward the wall 16. The top of the said dischargechamber may be formed by the bottom wall of the tank 10. `The lower and rear edge of the said wall 17 is spaced from the wall 16 so as to provide a transversely inclined slotlike discharge-opening 18 extending the full length of the discharge-chamber.

The ends of the discharge-chamber 15 are formed Haring as shown in Figs. 1, 3 and A, the triangular end walls 19 of the chamber being inclined downwardly and outwardly. rlhe said discharge-chamber 15 communicates with the interior of the tank 10 by means of a valved-opening 20 disposed centrally or eccentrically with reference to the longitudinal axis of the device. This opening is shown as provided with an upwardly extending-rim seat 20a on which a vertical valve 21 normally rests, the stem of the valve being suitably guided in the upper and lower arms of a bracket 22 xed to the interior of the said tank 10. A forwardlyextending lever 23 is pivotally connected at its rear end to the stem of the said valve 21 and fulcrumed intermediate its length on a pivot-pin 2A which is carried by an eyebolt 25; the latter passes through and is secured to the tube 13 and the rod 12 whereby the said rod is held against turning. A vertical operating rod 26 is pivoted at its lower end to the forward end of the said lever 23 and is provided with a forwardlyprojecting handle 27 within convenient reach of the operator. The rod 26 has a catch 2S which is adapted to engage with a lip 29 formed from material removed from the top of the tank to afford the opening through which the rod 26 operates. A tension spring 30 secured at its upper end to thetop of the tank 10 and at its lower end to the forward part of the lever Q3 holds the valve 21 normally seated, the said catch 2S being engaged with the lip 29 to hold the valve open against the tension of the spring. A horizontally-elongated baffle-plate 31 is supported within the discharge-Chamber at a certain distance below the top thereof and directly beneath the opening Q0, eX- tending for a considerable portion of the length of the chamber so as to distribute the descending oil or asphalt to the end portions of the chamber as well as to the part thereof more immediately below the opening. The said plate 31 is preferably as wide as or wider than the opening 2() and may be supported at its ends by bent-up lugs 32 with liquid.

secured to the top wall of the chamber.

As shown in Fig. 3 there may be a single valved-opening 20 for supplying the entire length of the discharge-chamber 15 Fig. 1 illustrates how the discharge-chamber may be divided by a transverse partition 33 into separate compartments, one of the compartments preferably being materially longer than .the other, so that a considerable variation 30l in the width of the strips oiled can be secured by discharging the liquid from the longer compartment or from the shorter compartment or from both. In this case `the smaller compartment is provided with a similar valved-opening 20", the valve of which is operated in a similar manner by a rod with a handle 27a through a lever 23a, the two valves being independently operable. A gate 34, shown in the form of an angled-plate is clamped to the front wall 17 of the discharge-chamber by means of wingscrews 35, which are secured to the side wall 17 and pass through transverse adjustingslots 36 in the plate, in order t-hat the plate may be slid up and down and held at any point of adjustment, thereby enabling the width of the slot-like discharge-opening, and therefore the quantity of liquid discharged, to be quickly regulated at will. Supplemental gates or plates 37, each materially shorter than the plate 34, enable the rate of discharge through different portions of the discharge-opening to be regulated in- .dependently- These supplementary gates 37 are shown as provided with slots 38 rcceiving the same bolts as the slots 36, so that the supplementary gates are adapted to slide back and fort-h to regulate the How through the end portions of the dischargeopening.

The angled-flanges 39 of these short plates 37 may be located at their upper ends so as to constitute stops for engagement with the upper edge of the main regulating-plate 34, the plates 37 being disposed between the plate 34 and the wall 17.

In order to prevent obstruction or irregularity in the flow of the liquid into and from the discharge-chamber by the attempted passage of air upward through the valved-opening 20, a vent-pipe 40 is provided, the latter extends upwardly from one end of the discharge-chamber 15 outside of the tank 1() and terminates with its open upper end at a suitable elevation.

A fire-box 41 is removably located immediately below the tank 10, for the purpose of heating the oil in cold weather or when desirable.v The said fire-box `41 is preferably constructed from a single sheet of metal in the form of a tray or shallow box consisting of a bottom, two sides and a rear end wall, the top of the boX being formed by the bottom of the tank 10 and the front end of the box by a door 42 hinged at its upper edge to the front wall of the tank and preferably inclined downward and forward so as to remain closed by gravity, the front end of the fire-box being correspondingly beveled. The fire-box is hung low with its bottom at a short distance above the level of the ground, so that it acts effectively to heat the top of the road as well as the contents of the tank. The lire-box is detachably supported by means of side hangers 43 which are removably secured at their upper ends to the sides of the tank by means of bolts and nuts 44, the bolts being received in horizontal slots 45 formed with the side edges of the hangers. The door 42 may be held open by means of a chain 46, the links of which are adapted to engage with a hook 47 on the front of the tank. In order to prevent the tire-box from slipping forward, a lip 43 is bent down from the material of the bottom of the box at the rear end thereof so as to engage with the edge of the rear hanger 43, the opening left by the removal `of this material being closed by the horizontal port-ion of this hanger. A flue 49 extends upwardly from an opening in the bottom of the tank 10 through an opening in the top thereof so as to receive a chimney section 50 at its upper end and to pro-. ride draft for the fire-box.

The top of the tank is provided with two hinged covers 51 and 52, provided with suitable handles, the latter being located in front of the chimney and affording access, to the main portion of the tank and the former being in rear of the chimney and affording access for purposes of illing the tank. A strainer basket 53 is hung within the opening covered by the lid 51, to prevent the interior of the device being choked by solid or semi-solid matter. A baffle or i wash plate 54 disposed transversely within the tank intermediate the length thereof but not extending quite to the bottom prevents the liquid contents of the tank from washing back and forth too violently. A

gage 55 is provided at one side and at the front of the device, preferably in alinement with one end of the discharge-chamber 15 so that the line connecting them is parallel with the wheels. The said gage 55 is within convenient range of the eye of the operator drawing the device and enables him to tell at a glance whether he is drawing theapparatus so as to oil a strip the margin of which touches or overlaps the strip previously oiled. The gageV is shown in the form of a vertical rod 55 slidably held for vertical adjustment by means of a set-screw 57 in a bracket 56, the bracket being secured to one of the shafts 14 as by means of a set-screw 58. A bib 59 at the forward end and bottom ofthe tank enables the latter to be drained. A stop 60 projecting below the edge of the rear wall 16 constitutes a guard to prevent the discharge opening 18 and therewith connected parts from touching the ground.

rllhe operation of the device will be rea-dily apprehended. The tank is filled with liquid asphalt or oil as the case may be, the operator takes his position between the shafts, opens one or more of the valves, and draws the device forward along the road thus coating a strip thereof with the liquid contents discharged at the rear. He proceeds in like manner drawing the cart back and forth so as to coat successive strips until the oiling of the entire width of the road is completed. He can regulate the rate of flow of the liquid from the device and also the horizontal width of the discharge, the latter ability enabling him to save material when oiling the last unoiled strip of the road which may be materially narrower than the maximum strip for which the device is adapted. Vhen it is desired to heat the contents of the tank and the surface of thev road, the operator attaches the firedoox beneath the tank and places live brands therein, though the fuel may be ignited if desired after being placed in the box. The remainder of the operation has already been described.
