Mott, La Grange Par 1111., assignor to Elgin Sweeper Company; El'gin,f lll.,. a corporation of Illinois Application January 2, 1i8","seiai a. 155
This invention relates to. improvements in street sweeping machines, and more particularly to machines of the type which sweep up and collect dirt and debris from the surface of 'a street as the machine is propelled ther'ealong, the
sweepings being collected in a dirt box or hopper carried by the machine.
As commonly constructed, street sweeping machines include a dirt box into which sweepings are directed from the sweeping brush, and means are'provided at thebottom of the dirt boxfor' dumping the collected contents when the dirt box is to be evacuated. Howeventhe evacuated j contents can assume only .a shallow pile where the receiving surface is at the traction level of the wheels of the sweeper, or thesweeper'must be run to the edge of'a depression which is to receivethe evacuated contents. Where no" permanent dump is handy to the sweeper in the particular area or zone in which it is operating,
it generally is necessary for the sweeper periodically to dump its contents of accumulatedsweepings in the street or other prescribed'placefor pick-up by a truck which will haul the same'to a disposal point. This, requires re-handling of the sweepings and adds asubstantial laborand handling cost to the street sweeping operations.
An important object of the present invention is to provide a street sweeping machine which is so constructed and arranged that sweepings collected thereby can be dumped directly into the hopper or body ofa, truck or onto a relatively high ile of sweepings directly at a disposal point where that is convenient.
Another object of the invention is to provide '1 Claims. (01. 15-53) rials swept up by the brush assembly, means for selectively elevating said dirt box to a height substantially above its dirt-receiving height for dumping the contents thereof at a substantially greater elevation than the normal dirt collecting' elevationpf the dirt box.
According to other general features of the in- ,vention, the. means for elevating the dirt box comprises a'parallel linkage system.
According to additional general features of the invention, the means for elevating the dirt box includes hydraulic actuation mechanism.
According to still other general features of the invention, there is provided in a street sweeping machine of the type which is propelled along a street to beswept and has a sweeping brush structure, a dirt box, means for directing sweepings from the brush structure into the dirt box, the dirt box being detachably associated' with the machine, and means connecting the dirt box' to the machineand constructed and arranged to respond to the will of the operator of the sweeping machine to lift the dirt box to an elevated position from which the contents of the dirt box can be dumped into the body of a tr'uck in' which the dumped sweepings can be hauled away from the sweeping site.
Other objects, features and advantages of the present invention will be readily apparent from a street sweeping machine having an elevating type of dirt box which can be raised to a sub- -stantial height for disposition in overlying relation to'a truck body or the like which is to receive the accumulated sweepings from the dirt box. v r Another object of the invention is to provide in a street'sweeping machine means for receiving and accumulating a substantial volume of sweepings at a point relatively close to the sweeping brush assembly of the'machine and which isadapted to bemoved to an elevated position to permit dumping of theaccumulated contents of the sweepings therefrom to an elevation substantially above the n0rmaloperating elevation of the machine.

Figure 2 is a top plan view of the street sweeping machine; and
Figure 3 is a fragmentary side elevational View of the machine of Figure l and a portion of a truck and showing how sweepings accumulated by the sweeping machine can be dumped into the truck to be hauled away.
' The present invention is especially applicable to self-propelled street sweeping machines, such as that illustrated, and including a body it supnection between the wheel assembly and a motor,
ported on a chassis l I resting upon a three wheel -arrangementincluding a single rear wheel 52 and a pair of spaced coaxial front wheels 83.
The machine is propelled by suitable driving consuch as a gasoline engine within a rear housing Hi. In Figures-l and 3, the particular manner in which the ,front wheels l3 are connected to th thassis llgha s been omitted to avoid obscursweeping broom I 8 which isfsupported l9 and is operable to rotate swepingly'forwardly,'
as indicated by directional arrow to sweep up dirt and litter from the street along which theinachine is propelled into a downward extension 20 of the body l providing a forward sweepings accumulator. The machine is also equipped with the customary rotary side brooms for jbruslie jl by which accumulations of litter in the gutters of the street being cleaned a're js wept fin'to' the path of the main cylindrical 'sweepingbroom 1'8.

A great convenience is airorded-by the present elevating type 'of'dirt bucketand substan- T or the truck T is backed under the elevated dirt bucket and the sweepings contents of the dirt bucket discharged as indicated by the directional arrows in Figure 3 upon opening of the dump door 21.
Inasmuch as the dirt box or bucket 22 is supported by the parallel linkage 3ll3l, its axis does not shift in any position thereof as it is swung between loading and dumping positions as indicated by the dash 'line S in Figure 3. Thus, there is no danger of spilling of the contents as the dirt bucket is' elevated.
From-Figures 1 and 2, it may be observed that the dirt box or bucket 22 is preferably dimensioned so as to blend harmoniously with the forward portion of the sweeper machine body I 0;
That is, the upper surface of the dirt bucket is preferably formed to blend coplanar with the front to rear curvature of the top of the body ID. The sides of the dirt bucket are preferably formed to extend in the same planes as the respective sides of the body [0. This not only affords an attractive appearance for the machine as a unit, but also facilitates and simplifies the construction of the machine.
Where preferred, of course, the relationship of the mouth of the dirt bucket 22 to the sweeping broom l8 may be such that the sweepings will be impelled directly into the dirt bucket.
It will, of course, be understood that various details of construction may be varied through a wide range without departing from the principles of this invention and it is, therefore, not the purpose to limit the patent granted hereon otherwise than necessitated by the scope of the appended claims.
