TROUGI-I FOR DISTRIBUTING CONCRETE.

Application filed August 19, 1915.

To all whom it may concern:

Be it known that I, HAROLD DANIELSON, a citizen of the United States, and a resident of Passaic, in the county of Passaic and State of New Jersey, have invented a new and Improved Trough for Distributing Concrete, of-which the following is a full, clear, and exact description.

This invention relates to distributing or spreading machines and particularly to a machine for distributing concrete after the same has been mixed, and has foran object the provision of an improved arrangement whereby the mixed and wet concrete will be distributed evenly and automatically over any desired space.

Another object in view is to provide a distributing trough for distributing concrete from a mixer, the arrangement being such that the concrete is discharged in a continuous stream and at any point desired within a limited radius.

A still further object in view is to provide a distributing trough for concrete which may be collapsed or reduced in length so as to distribute at a distant point from the source of supply or at any intermediate point without changing the position of the source of supply.

Another object of the invention is to provide a distributing trough with propelling means for forcing in a substantially continuous stream concrete to the discharge point of the trough.

Another object is to provide means for swinging the trough from one position to another by power and for adjusting the trough by power, whereby the concrete forced therethrough may be discharged at any point and to any extent.

In the accompanying drawings :Figure 1 is a side view of an 'embodiment'ofthe invention applied to a mixer, certain parts being broken away for better illustrating the invention; Fig. 2 is a detail fragmentary view taken approximately on tlfe line 2-2 of Fig. 1: Fig.3 is an end view of the trough and associated parts shown in Fig. 1, the same being on an enlarged scale; Fig. 4 is a section through Fig. '1 on line 4-4, the same being on an enlarged scale; Fig. 5 is a fragmentary plan view of one end of, the trough and associated parts shown Fig. 1.; Fig. 6 is a fragmentary sectional view through Fig. 1 on line 66, the same Specification of Letters Patent.

being on an enlarged scale; Fig. 7 is a fragmentary side view of the outer end of a slightly modified form of trough and assoclated parts showing a positive drive for adjusting the collapsing of the trough; Fig. 8 is an end view of the structure shown in Fig. 7.

Referring to the accompanying drawings by numerals, 1 indicates a concrete mixer of any desired construction, said mixer being provided with a suitable framework 2 which forms no part of the present invention. Connected with the framework 2 is a cable or guy rod 3 which also is connected at a to the trough 5 for supporting the outer end, the inner end resting on the shaft 6 forming part of the mixer 1. rotate when the mixer 1 is in operation and may be connected with the mechanism associated with trough 5 or said mechanism may loosely rest on the shaft, as desired. The trough 5 extends from thebracket 7 to the frame 8, which frame is supported by the guy rope or rod 3, as clearly shown in Fig. 3. This trough is preferably formed of sheet metal and lined with wood saturated in some mineral oil, as for instance, crude oil, whereby the concrete will not readily stick thereto.

An opening 9 is provided in the bottom of the trough, said opening extending to point 10 (Fig. 1). In order that the concrete will. not fall through the opening until it has arrived at the desired locality, a plurality of covering members or slides 11, 12 and 13 are provided. It is evident that any desired number of slides could be provided and they could be made of any desired length. The provision of these slides is to allow the concrete to be discharged from the trough 5 at any point'between the outer end and point 10, the various slides being gradually moved inwardly and telescoped over each other as the concrete is laid. For instance, in starting the operation the parts are in the position shown in Fig. 1, and after a certain amount of the concrete has been discharged from the outer end of the trough, slide 13 is moved gradually inwardly, the concrete being continually discharged. After the slide 13 has been moved in for its full length the stop 14 arranged on the hanger 15 will strike against the hanger 16 on slide 12 and will consequently move slide 12 inwardly as the slide 13 is forced inwardly. The movement of both these slides will continue until the Shaft 6 is adapted to I stop 17 strikes the hanger 18 which will move hanger 18 inwardly with the remaining slides. When all of the slides have been moved inwardly until the end has been exposed, no further movement can be made as this is the limit of the device. The mixer and associated parts must then be moved to the rear and the slides 11, 1 2 and 13 moved out again to their full extent and the operation repeated. It is to be noted that in laying concrete on a street or other surface of appreciable width, the trough 5 is swung from one side to the other, back and forth, so'as to discharge the concrete evenly over the entire surface.

The slide 13 is provided with hanger 1e and with a hanger 13, while slide 12 is provided with hangers 16 and 16, and slide 11 is provided with hangers 18 and 18. These hangers are provided with antifriction rollers :19, as shown in Fig. 3, which rollers are mounted upon a plurality of supporting angle irons 20. It .will be observed that the hangers 15 and 15 are spaced farther from the trough than the hangers .16 and 16",

'while these last. mentioned hangers are spaced farther from the trough 5 than the hangers 18 and 18. .This will allow the outer slides and hangers to telescope over the pulls the same outwardly, and after this hanger has been moved for its full length the same will move the hook-shaped stop 22. connected with hanger 16", which hook-shaped stop will engage thehanger 18 and move the inner slide l lfoutwardly; It will thus be seen, that the slide 13 is the only slide that need be operated directly as the other slides operatefrom: this slide. This, slide may be operated manually as arrangedin Fig. 1, or maybe connected with power means for operating the same, as shown in Fig. 7' and hereinafter fully described. Also, the trough 5 and associated parts may be swung manually or may be swung by power, as hereinafter described. 7 g i 5 Arranged i n'trough 5 is a screw 23' which is. supported by suitable bearing members arranged on the frame 8, frame 8" and bracket 7'. The shaft Ziforming part of U I thescrew 23"exte'nds. through the frame 8 at the outer end of the trough 5 and has a: sprocket wheel? 25" rigidly secured thereto. 7

7 A chain. 26 (Fig. 13'); passes over sprocket .wlieel 25 and also a sprocket wheel 27 rig.- idl-y secured to shaft 28. Shaft 28 is journai ed in the upper part of the frame '8 and also is journaled in a bearing 29. The inner end of the shaft 28 near bearing 29 has cured thereto a gear wheel 30 which meshes with gear wheel 31 connected to and operated by a motor 32 of any desired construction, as for instance, an internal combustion engine. As motor 32 operates the power will be transmitted through the structure just described and screw operated. A beveled gear 33 is rigidly secured to shaft 24: near bracket 7, said gear meshing with a beveled gear 3%, which beveled gear has a. sleeve 35 rigidly secured thereto, said sleeve being preferably part of another beveled gear 36 meshing with a power beveled gear 37. lVhen the engine 32 is operat ing the power beveled gear 37 is loosely mounted upon the shaft 6. However, a small beveled gear 38 meshes with the power beveled gear 37 and operates shaft 39 to which the friction wheel 10 is secured. The bracket 4-1 which supports shaft 39 also supports a shaft -2 which has splined thereon beveled friction wheels 43 and 1 said beveled friction wheels being connected hr a sleeve 45.

hen the parts are in the position shown in Fig. 1 shaft 4-2 will be driven in one direction, while if they were moved to the opposite extreme by the controlling lever +16 shaft 42 would be rotated in the opposite direction. Shaft d2 carries a pinion 17 at one end which meshes with a gear ring &8, as shown in Fig. 5, which gear ring is held in place by guides 49 and 50. The gear ring 18 continually meshes with a pinion 51 rigidly secured to arms 52, which arms are preferably formed integrally with the bearing plate 53, said bearing plate being also cast integral with the bracket 7 and bracket 7. The bracket 7 is bifurcated so that thetrough 5 may rest therein and may be secured thereto in any desired manner, as for instance, screws or bolts.

By the construction and arrangement just described, when lever 4L6 is operated, as shown in Fig. 1, so that wheel 4-3 will press against wheel t0, power will be transmitted to shaft 42 and from thence through the mechanism just described to the bearing plate 53 and from thence to bracket 7, from which it is transmitted to the trough 5 so as to swing the trough in one direction. The speed of swinging movement is regulated'by the pressure brought to bear on the wheel 43. lVhen it is desired to swing the trough in the opposite direction lever 43 is moved in the opposite direction so as to cause wheel 44 to engage the wheel 40. In case the engine 32 is not used the power beveled gear 37 iskeyed to shaft 6 whereby power from shaft 6 will be transmitted to the parts just described for rotating the screw 23 and also for providing rotary movement for wheel so that the trough may be swung back and forth as desired. The trough 5 is preferably open for the full len th at the top while the inner end 5 is closed so that the concrete will move only in one direction. In order to better direct the concrete which is discharged from the mixer 1 a hopper is provided which may be of any desired width, as shown in Fig. 6, for directing the concrete to the trough.

In the construction shown in Fig. 1 the various slides 11, 12 and 13 are moved manually back and forth, but as heretofore mentioned, these slides may be moved by power, if desired, from the inner end of the trough. As shown in Fig. 7, means are presented which will move the various slides in and out as desired, such movement being automatically produced, or produced manually if desired. In producinga structure of this kind the sprocket wheel 27 is connected with a shaft j ournaled in the upper part of the frame 8. Shaft 55 carries a gear 56 and pinion 57, pinion 57 continually meshing with an idler 58, said idler being designed to mesh with gear 59 when moved to the position shown in Fig. 7. "Whenever desired gear 59 may be moved into mesh with gear 56 by operating lever 60, the gears sliding on the shaft 61. Shaft 61 carries a beveled gear 62 which meshes with beveled gear 63 rigidly secured to shaft 64:. Shaft 64 carries a pair of sprocket wheels 65, as shown in Fig. 8, whereby a pair of chains 66 may be operated. The chains 66 are connected to the opposite hangers 15 by any suitable means, as for instance, U-bolts 67. By this construction and arrangement it will be seen that when the screw 23 is operating power will be transmitted to the chains 66 for gradually moving the outer slide 13 inwardly and eventually all of the sides inwardly. By operating lever the direction of movement of the chains 66 may be changed so that the slides will move outwardly.

It will be observed that gear wheel 56 is larger than gear wheel 57 so that the out ward movement will be faster than the inward movement in proportion to the speed of the screw 23.
