APPARATUS FOR DISTRIBUTING CONCRETE.
Specification of Letters Patent.
Patented Apr. im, 191W.
To all whom z' may concern.'
Be it known that I, ALFRED D. Moser, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Distributing Concrete, of which the following is a specification. q
My invention relates to an apparatus for distributing concrete, or such lik-e material, and the principal object of the invention is to provide an apparatus adapted to receive concrete from a concrete mixer and mechanically distribute the same, for example, in street paving work, over a considerable area, thereby doing away with the neces sity of transporting the concretein batches to the places where required by the use of wheel barrows, or the like, which has here tofore been ordinarily practised in work of discharge end of the distributing .trough;
Fig. 3 is a vertical sectional View taken on line 3-3 of Fig. 1.
Figs. 4, 4a, which should be 'read together, show the apparatus in longitudinal section, the section line being indicated at 4-4 on Fig. 3, Fig. 4 showing the inner end of the distributing trough and the parts of the apparatus associated therewith, and Fig., 4a the outer end of the trough. l ,i
Fig.. 5 is a vertical sectional view taken on line 5-5 ofv Fig. 4a.
Fig. 6 is a plan view, with certain parts in section, of the inner end of the distributing trough, the feed hopper therefor and adjacent partsof the apparatus.
Fig. 7 is a fragmentary View, partly in elevation and partly in section, illustrating a modified form of apparatus.
Fig. 8 is a similar view illustrating another modification.
Like characters of reference designate like parts in the severa-l figures of the drawings.
Referring first to Figs. l to 6 inclusive, a portion of the truck or wagon on which the apparatus is mounted is shown at A. B is the drum of a concrete mixer of the revoluble drum type, and C the discharge chute of the mixer by means of which the concrete, when mixed, is delivered from the drum. D is a distributing trough which is preferably pivotally mounted at its inner end on the truck A in such manner that its angle of inclination, with respect to the f ground, may be varied to the extent, for
example, indicated by line a. in Fig. 1, and so that it may be swung laterally within certain limits indicated by the lines b, Z)
`in Fig. 6. E is a hopper which receives concrete from the discharge chute C of the mixer and delivers the same into trough D. F is an endless double chain provided with paddles or buckets G by means of which the concrete is carried along through the distributing trough. The bottom of the trough is formed at intervals with discharge openings adapted to be closed by gates H. It terminates in a, discharge chute J and by swinging the trough on its vertical pivots the concrete from the mixer may be delivered at any desired point within the range of the machine. The trough D is secured between a pair of angle irons 25 which are attached to angles 26 secured at their inner ends to castings 27 and at their outer ends to plates 28. Belowiangles 2G is another lpair of angles 29 likewise secured to castings 27 and to the plates 28. A truss frame 30 is-:ittached to the plates 28 and by means of members 31 to the angles 26,29. The trussframe is provided 'at its upper end' with plates.l 32 adapted to be secured by a bolt 33 to plates 34 on theuprights 35 (Fig. 3). The castings 27 are connected by pivot pins 36 to lugs 37 on a casting 38 to opposite sides of which the uprights 35 are secured. The casting 38 is formed with a vertical bearing 39 by means of which the casting is pivoted on a stud 40 projecting upwardly from the flooring 41 of the truck. Secured to the upper ends of uprights 35 is a plate 42 pivoted by means of pivot pin 43 to a plate 44 on a framework 45 rigidly mounted on the truck A. The pivot points provided by pin 43 and stud 40 are, of course, in line with each other. The structure carrying the distributing trough D may, therefore, swing sidewise on pivots 40, 43, the limit of movement being indicated by lines b, b in Fig. 6. The portion of the trough supporting structure composed of the truss frame 30,
` casting 27 and the parts rigidly connected therewith may be turned about pivot 36 so as to change the inclination of the trough, the limit of upward movement of the trough being indicated by linea in Fig. 1. In order to hold the trough at any desired inclination the plates 34are provided with a plurality of perforations 46 for `the bolt 33.
The pair of chains F to which the buckets G are attached, are supported upon and driven by large sprockets 47 at the inner end of the troughwhich are fixed to shafts 48 mounted in bearings on the castings 27 and sprockets 49, at the outer end of the trough which are loose upon a shaft 50. The posi tion of the shaft 5.0 may be adjusted so as to give the chain F the proper tension by means of set screws 51 which extend through the ends of castings 52 and bear against the extremities of the shaft 50; the castings 52 being secured to plates 28 and being slotted for the ends of shaft 50.
The buckets or paddles G are preferably made of sheet metal and concave on the side engaging the concrete. They preferably fit rather `closely into the trough D. They are attached to cross slats v53 secured by angle pieces 53a to the chains F.
The chains F, which, in effect, constitute a single member, are preferably driven by a driving train connected with the mechanism forv revolving the mixer drum B. The driving train for the chain is disposed with respect to the vertical pivots of the trough supporting structure so that the trough may be shifted laterally without disconnecting the chain driving mechanism. The drum B of the concrete mixer is shown as provided With a circular rack or pinion 54 meshed by a pinion 55 on a shaft 56 which maybe driven by any suitable motor (not shown). 57. is a shaft mounted in bearings 58 on the floor of the truck and having keyed thereto a bevel pinion 59 which is meshed with a bevel pinio`n 60 turning on an extension 61 of stud 40. Mounted on the casting 38, which, it will be understood pivots on stud 40, is a shaft 62 having keyed to one end thereof a pinion 63 meshing with pinion 60 and on the other end a bevel pinion 64 meshing with a bevel pinion 65 on a shaft 66 turning in bearings G7 on the casting 38. On one end of shaft 66 is a sprocket wheel G8 connected by a belt 69 with a sprocket wheel 70 on the shaft 48 which carries the sprocket 47 for chain F. Shaft 57 has keyed thereto a sprocket wheel 71 driven by a chain 72 from a sprocket 73 loose on shaft 5G but adapted to be engaged therewith by a clutch 74 of any suitable construction. The pivots 3G, GG are so close together that the slight change of inclination of the trough does not interfere. with the proper operation of the driving chain G9.
In order to prevent the buckets from being injured by being brought into contact with too large a mass of concrete in the feeding hopper, the concrete is not fed from the hopper directly into the inner end of the trough B but is deiected to the sides of the hopper when falling into the same from discharge chute C of the mixer, and enters the trough B through openings in the sides thereof. To this end a deflecting casting 7 5 is arranged in the hopper E. The casting has a plow like point 7 6 directed toward discharge chute C. The surface 77 of the casting which faces toward the trough and chain F is curved transversely with a curvature corresponding to that of the buckets G and the lower portion of the same is also curved on lines concentric with the axis of sprocket 47 so that this portion of the casting provides, in effect, an upwardly curved continuation of the trough D through which the buckets G move when passing around sprocket 47. The hopper tapers down toward the trough D so that a spout portion 78 is provided of the same cross sectional configuration as the end of the trough. This spout alines with the trough as shown in Fig. 4 and, in effect, forms a continuation of the trough. The spout portion of the hopper is formed on the side with openings 79 to which lead passageways 80 on opposite sides of the defiecting member 75, these passageways being preferably covered by iianges 81 which, at their lower extremities, aline with the horizontal iianges of the angles 26 to which the trough D is secured; tracks 82 for the chain F being laid on the angles 26 and flanges 81. By this arrangement a limited amount of concrete is engaged by the buckets as they move around sprocket 47. Moreover, as thel buckets work over the curved surface 77 and between openings 79 there is no danger of stones, or such like hard objects, being caught between the buckets and the walls of the space in which the buckets operate and causing an injury to the apparatus.
so this 4position it forms a chute for the matenaaaom ya,
are formedpreferably by making the trough in lsections and spacingl theI sections apart.
'83, 84 in Fig. 4a indicate two of such secT tions. The gates H `for closing the discharge openings are, in edect, trough sections. '.lhey are preferably provided along their upper edges with strips 85 which project beyond the gates at one'end and are pivoted to the adjacent trough section, 83, for example, by rivets 86. The arrangement. is/` preferably ysuch that when the gate is in its closingV positionthe Vend thereof nearest the outer or discharge end of the troughv alines with the adjacent trough section, 84 forexain-ple, (Fig. 4f?) while the other end overlaps the next trough section 83. Secured to the, strips 85 are depending arms87 supporting and rigidly connected to a cross rodv 88 to the ends of which arepivoted links 89, the upper extremities of the links being pivoted to the arms of bell cranks 90 afxed to opposite ends of a shaft 91 preferably mounted 'in supports 92 attached to the angles 26, 29. The long arms 93 of the bell cranks serve as handles for manipulating the gates. rlFhe full lines in Fig. 4a show the gate and. its operating mechanism in'xthe closed position. 'llhe dotted lines indicate the gate in its open or lowered position. lln
rial discharged through the opening between sections 83, 84 of the trough.
'lhe trough is preferably open at its outer end and provided with a discharge chute .l
Asupported at its outer end by a strap 94.
"lhe sla-nt of the discharge chute -J begins inwardly of the axis of sprocket 49 so that the material discharged through the open end of the trough clearsy the buckets betore the latter begin to tiltl upwardlyl rlhis arrangement prevents the. buckets from throw.- ing the material out of the trough. llt is desirable to give the distributing trough a v any one of a series of perforations 97 in an lib vte
fixed position during the distribution of the .n material along any given line, changing said position lby swinging the trough on pivot 40, as ,occasion requires. To thisend the casting 38, which supports the distributing trough and associated mechanisms, is formed with a lug 95 having a vertical perforation to receive a locking bolt 96 adapted to enter extension 98of the ooring of the truck. Pllhe lug is formed with a clevis 99 in which is arranged a forked lever 100 mounted on a rockshaft 101, the fork .of the leverengaging a cross pin 102 arranged in a slot 103 in the pin 96. rlFhe rock shaft 101 carries on opposite ends levers 104 to which .y is attached a cord 105' running through guides 106 on the members 31 of the supn porting structure for tro-ugh D, anchored to staples 107 on plate 28. By' this arrange` ment the distributing trough may be locked in the desired angular position by a workman standing. on either side of the trough and at any point along the same.
'.lhe purpose of the modified construction shown in Fig. 7 is particularly to eliminate the` somewhat heavy and cumbersome frame member 35 forming part of theapparatus above described. In the construction shown in Fig. 7 the supporting frame 30 for the distributing trough D is pivoted directly to the framework 45 by a vertical pivot pin 43.- The casting 27 is likewise pivoted to the flooring 41 o-f the truck, and in addi- `tion is provided with rollers 111 'which 'run upon an arcuate track 112 on the truck. ln other respects this apparatus may be constructed the same as that previously described.
ln Fig. 8 l have illustrated another modification in which a screw conveyer l ,is employed instead ofthe chain Fl and buckets G an extension 120 of pivot 114. llhe pinion 119 is meshed by a bevel pinion 121 carried on a shaft 122 ycorresponding to shaft 57 in the machine shown in Figs. 1 to 6 inclusive. Thefsh-aft carrying a sprocket wheel 123 is driven by a belt from the driving shaft of the drum as in the machine hereinloefore described. r1he bearings ,of shaft 117 are protected by a felt packing 124 and cap 125.
lWhile ll have described my invention in certain preferred embodiments,` it will be understood that further modifications might be made without departure from the invention. illherefore .l doV not wish` to be understood as limiting the invention to the particular'constructions, arrangements and devices above spe'ciied except so far as the claims are expressly so limited.
ll have used the -term chain to denote the endless 'flexible member by means of which theA buckets G are moved through the trough. lt willbe realized, however, that a belt would be an equivalent for the chain, although for obvious reasons, a chain is preferable.
