UNITED STATES JAMES F. MOORE, F VALLEY STATION, KENTUCKY.

ASPHALT DISTRIBUTOR.

Application filed March 29, 1923.

To all whom it may concern:

Be it known that I, JAMES F. Moore, a citizen of the United States, residing at Valley Station, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Asphalt Distributors, of which the following is a specification.

This invention relates to road making machinery, and has special reference to an asphalt distributor and pulverizer.

One important object of the invention is to improve the general construction of devices of this character.

A second important object of the invention is to provide a device of'this character having novel means for feeding the asphalt to a crushing device.

A third important obj ect of the invention is to provide an improved device of this character having a novel arrangement of primary and secondary crushing means.

A fourth important object of the invention is to provide an improved device of this character having a novel arrangement of feed bin.

With the above and other objects in view as will be hereinafter apparent, the invention consists in general of certain novel details of construction and combinations of parts hereinafter fully described, illustrated in the accompanying drawings and specifically claimed.

In the accompanying drawings like charseveral views, and:

Fig. 1 is a side elevation of the improved asphalt distributor and pulverizer.

Fig. 2 is a longitudinal vertical 'median section therethrough.

Fig. 3 is a plan view thereof.

Fig. 4 is an enlarged detail section of the primary crusher.

Fig. 5 is an enlarged detail perspective view of one of the teeth of the primary crusher.

Figure 6 is a detail perspective showing the manner of connecting the chain 21 and plate 28.

In the embodiment of the invention herein illustrated, there is provided a lower rectangular frame 10, which is supported on suitable ground wheels 11 at the front and back thereof. Extending diagonally upward from the front of this frame is a pair of rails 12, the upper ends of which connect with a pair acters of reference indicate like parts in the Serial No. 628,663.

of horizontal rails 13 supported by brace frame members 15. ()n the rearportion of the bottom frame 10 is carried a suitable motor 16, which is here shown as an ordinary internal combustion motor, and this motor serves to drive the various parts of the apparatus. These rails 12 and 13 support the sides 17 of a bin, which sides have inwardly directed bottom flanges 18 whereon rests a movable bin bottom 19, which is pivoted to a fixed bin bottom 20 at its rear end. and which, at its forward end, is provided with a chain and hook 21. x Mounted on the upper rails 13 is a winding drum 22, which is driven from the motor 16 by means of a suitable sprocket chain 23. Mounted to travel on the rails 12 and 13 is a carriage 2 1 having wheels or rollers 25., which engage said rails. This carriage 24: rests, in its lowered position, against an abutment 26 carried by the bottom ends of the rails 12. On this carriage is pivotally mounted a hopper .27, the hopper being pivoted to the lower or front end of the carriage, and this end of the carriage being provided with a plate 28 having a suitable opening thereinfor en gagement by the hook 21. The carriage 24 has at its upper or rear end atransverse plate 29 which connects the sides of said carriage. Wound on the drum 22 is a cable 30, which is connected to the hopper 27 at the upper rear portionthereof, as clearly shown in Fig. 1.

Leading downwardly from the fixed bot-- tom 20 is a chute 31 for conveying material from the bin to the lower end of a belt conveyor 32. which leads upwardly through a suitable housing 33. In the chute 31 is located a breaker wheel 34,-which includes a hollow cylindrical drum 35 havinga plurality of openings 36 therein arranged in. staggered relation to each other. The breaker teeth each consist of a body portion 37, a bent shank 38 which projects through a respective opening 36, and has its end engaged within the drum 35 against the inner side thereof, and a tail 39 which is secured to the drum by a suitable bolt 40. Thus these teeth may be readily detached or replaced in the event of wear or'breakage.

Beneath the upper end of the conveyor 32 is a crusher consisting of a plain wheel or drum41, and a corrugated or serrated wheel or drum 42, these two being placed sufficiently close together to thoroughly pulverizeany material passing between them.

Beneath the secondary crusher is a delivery chute which terminates in a swinging de livery spout projecting downwardly and tilts downwardly from the Iposition shown in full lines in Fig. 1 to the otted line position in that figure; Continued winding of the cable 30 moves the hopper and its carriage up the rails 12, and along the rails 13.

l V At the same time, the hook and chain 21 are engaged with the plate 28 so that the bottom of the bin folds up behind the hopper as it 'moves upward and rearward. By meansof this construction, any material spilling over the sides of the hopper will drop on thisbottom and thus, when the bottomhas its forward end raised, will move down to the delivery ohute 31. After the hopper and its carriage have been pulled fully up on the rails- 13, the winding'drum 22 may be reversed, a suitable controlling lever 49 being arovided for the purpose of controlling such winding drum, while a similar lever 50 controls the breakers and conveyor. Upon reversal of the winding drum, the hopper tilts downward to the position shown in dotted lines in Fig. 2, and thus dumps its entire load into the bin. The primary breaker then acts upon the lumps in the bin, and breaks them up in small sizes after which they pass 'upthe conveyor and are crushed by the secondary breaker or crusher, passing from thence through the chute 43 in finally commutated form to be spread on the roadway or be placed in suitable receptacles for conveyance elsewhere. 7 V a V There has thus been provided a simple and efiicient device of the kind described and for the purpose specified.

It is obvious that minor changes may be made in the form and construction of the invention without departing from the material spirit; thereof. It is not, therefore, desired to confine the invention to the exact form herein shown and described, but it is desired to include all such as properly come within the scope claimed. 7

Having thus described the invention, what is'el'aimed' as new, is:

1. In a device 01 the. kind described, a

-wheelsupported frame, rails on said frame extending upwardly and then rearwardly from one end of the. frame and other rails extending rearwardly in a substantially hori-zontal direction from the upper end of the first; rails, a carriage traveling on said rails, a dumping hopper mounted on'sald carriage,

means to move said carriage on said rails, a

bin under the rearwardly extending portion. of said rails, said b1n including a movable bottom member hinged at its rear edge to a fixed portion of the bin, and means for connecting the free edge of said bottom member" to said carriage.

2. In a device of the kind desor1'bed,.a.

frame including upwardly and rearwardly 7 extending rails and other rails extending, rearwardly in a substantially horizontal d rection from the upper ends of the first rails, a skeleton'carriage mounted to; move along said rails, a hopper pivoted at its bottom to the lower and forward end otsaid carriage, V

a winding drum at the rear end of saidsec- 0nd rails, a cabl connect'lng'the upper end of said hopperwith said. winding drum, said 7 hopper being adapted V tofswing freely .be- I tween the Sides ofthe carriage whereby the. hopper may be inverted in position through the car-riage,'and a bin beneath the second 'mentioned rails to receive the contents of said hopper.

3. In a device of the kind described,
