STREET-CLEANING MACHINE.

known for brushing and scrubbing and more particularly has reference to a streetcleaning machine.

As the primary aim and object, this invention contemplates the provision of a machine of the above mentioned character wherein improved cooperative sweeping, elevating and conveying means are arranged to operate simultaneously with respect to each other so as to assure the removal of dirt from the street and the depositing of the dirt within a receiving compartment in the body of the machine. v

It is an additional object of this invention to provide a machine of the above mentioned character wherein the elevating means is designed to operate through the dirt receiving trough at the forward end of the body of the machine'so'as to remove the dirt from the trough and elevate it and consequently deposit it on a conveying means which inv turn conveys the dirt to the dirt receiving compartment.

As a further improvement this invention includes the provision of improved cooperative guiding and tripping means designed for use in con unct1on with swinging buckets of the elevating means so as to assure of the proper actuation of the buckets during the operation of the machine.

It is a more specificobject of thisinven- 7 tion to provide improved sprinkling means 5 the cost of for sprinkling or spraying the dirt in the dirt compartment in the body for preventing dust, etc.

Among the other aims and objects of this invention may berecited the provision of a device of the character described with a view to compactness, and in which the number of parts. are few, the construction simple and production low and the efliciency highp, I 1' I V Other objects as well as the nature, characteristic features and scope of this inventionwill be more residilyapparent from the following description taken in connection Specification of Letters Patent.

with the accompanying drawings and pointed out in the claims forming a part of this specification.

The invention is clearly illustrated in the accompanying drawings, wherein:

Figure I is a longitudinal sectional View of the invention. i

Fig. 2 is a top plan View; of the machine with the top of the body removed.

Fig. 3 is a transverse section taken on the line33 of Fig. 1 in the direction in which the arrows point.

Fig. 4C is a transverse section taken on the line 4.4 of Fig. 1 in the direction in which the arrows point. i

Similar characters of reference are employed in all of the above described views to indicate corresponding parts.

Referring now, more'particularly, to the accompanying drawings, there is provided a motor vehicle consisting generally of a frame 1 the rear portion of which is designed for a body or casing 2 of a rectangular figuration. A rear axle 3 is journaled through the rear portion of the frame or body and has supporting wheels 4 operably mounted on the respective ends thereof while other supporting wheels 5 are also mounted on the respective ends of the front axle 6. A hood 7 is mounted on the forward end of the frame and is adapted .to cover suitable motive power while the transmission box or casing 8 is mounted beneaththe body near the forward end thereof. A rotatable shaft 9 extends from the transmission box 8 and carries on its outer end a sprocket wheel 10 over which operates a chain 11 which in turn is trained about another sprocket wheel 12 at the end of the rear axle 3. A driversseat 13 is mounted forwardly on the body in spacedrelation to the dash while the steerstruction and this invention'is not limited to the particular construction shown as it is apparent that other means may be employed for transmitting motion to the rear axle and likewise it is unnecessary to employ motion transmitting means to the rear axle.

The bottom of the body 2 is formed near its front end with anopening while journaled through the sides ofthe body above ing wheel 14: is operably connected tothe v the opening is a transverse shaft 16 on which is carried a rotary sweeping brush 17 consisting of a cylindrical body 19 from which projects bristles 18. This brush of-course, is po sitioned through the opening 15 while the bristles are designed to be engaged upon the ground for sweeping dirt etc. A dirt receiving trough 20 is formed in the bottom of the body near the front end thereof while an inclined apron 22 depends from the trough and is positioned in the opening 15 and in closely spaced relation to the ground and in proximity to the brush bristles 19 so that the dirt which is swept from the surface of the street will be directed up the apron and will be deposited in the trough 20.

In order to actuate the sweeping brush simultaneously with the actuation of V the motor vehicle a stub shaft 23 is journaled through one side of the body or casing and has a sprocket wheel 24 mounted on the outer end thereof and over this sprocket wheel a chain is trained; .This chain is also trained about another sprocket wheel 26 on the opposite end of the rear axle 3 that during the rotation of the rear axle 3 of the stub shaft will be rotated in a corresponding direction. A gear 27 is also carried by the shaft 23 and is positioned adjacent the outer face of the side wall of the body and meshes with another gear 28 V on the projecting end of the shaft 16 and is designed to be rotated in the opposite direction from the gear 27 and the shaft 23 so as to consequently assure of the brush 17 sweeping the dirt upon the apron 22.

With a view toward providing the improved elevating means for removing the dirt from the trough 20, a plurality of shafts 29 are arran ed at right angles to the front wall and longitudinally of the body having their respective ends journaled in the front wall and in brackets 30 and 31 which extend respectively from the opposite points on the side walls and from the upper end of the apron 2 the shafts being positioned in proximity to the opposed upper and lower corners of the body as indicated in Fig. 3. Sprocket wheels are carried on each of the shafts 29 while operating about these wheels are spaced endless chains 33 between opposed links of which and at uniformly spaced intervals throughout their lengths are swinc'inc'lv connected transverse buckets 34 which may be and preferably are substantially l-shapcd in cross section. i It is Y to be observed that the upper and lower and side lays of the chains 33 are respectively arranged in close relation to the upper and lower and side walls of the body. A wear plate 35 is mounted in the bottom of the 1 '1 00 .j "i u 11 g riou 1 2 inc an arcua c Jooc is mount ed in one end .of'the trough and extends upwardly in close relation to one side wall and is designed to cooperate With the buckets 34s as they pass through the trough.

,Thel'i ckets are connected so that they will normally lie in an upright position. In order to trip the buckets immediately before they enter the trough a tripping pin 37 extends outwardly from the inner surface of the front wall in proximity to the wear plate and lies in the path of movement of the buckets and is designed to successively swing the buckets into a substantially inverted position so that one of the side edges of each of the buckets will be engaged on the wear plate while the relation of the lower leg of the chain is close to the wear plate so as to prevent the buckets from ri ht then'iselves until they have passed by the boot 36. In tripping the buckets of the upper lay of the chain a guiding shoe 38 extends from the front wall and lies in the path of movement of each of the buckets so as to swir h lrickets aoout their pivots when engaged therebu In this connection it is to be noted, the shoe is arcuate while extending from the front wall is another tr m'iing pin 39, which is designed to engage the upper edge of each of the buckets im mediately after th' ss over the shoe and assure of a complete dumping; of the buckets for purpose which will presently become arent.

In actuatino the elevating means simultaneously with the sweeping means a bevel ear 40 is mounted on one projecting end of one of the shafts 29 and meshes with another hovel gear 41 carried by the stub shaft 42 journaled transversely in one side wall of the body. A sprocket wheel 48 is carried by the outer projecting end ofthe stub shaft 42 while a chain 44 operates about the sprocket wheel 43 and also about another sprocket wheel 45 carried by the projecting end of the shaft 16. This motion transmit ting means, of course, assures of the actuation of the elevating means.

Cooperating with the elevating means is the in'iproved conveying means and this conveying means consists of a lower shaft 46 journaled in brackets 47 which project from the front wall and terminate so as to position the shaft beneath the upper lay of the chains of the elevating means. Another shaft 48 is journaled transversely in the sides of the body near the top thereof while one end projects beyond one side of the body. Spaced sprocket wheels 49 are mounted rigidly on the shafts 46 and 48 while operating about the alining sprocket wheels on the shafts are endless chains 50. Tl ese chains carrv an endless belt 51 which has mounted transversely thereacross at uniformly spaced intervals a plurality of stationary buckets 52. The conveyer, of course s inclined unwardly while the upper lay moves in the direction toward the rear end of the body so'that the dirt Whichis deposited from the swinging bynck'ets 34 falls upon the endless belt 51 and in the buckets 52 and, of course, is conveyed upwardly and subsequentlv deposited in the" Suitable means for actuating the convey-.

ing means simultaneously with the sweeping means and the elevating means and in the same direction as the sweeping means consists of the sprocket wheel56 carried by the projecting end of the shaft 48 and over which sprocket wheel operates a chain 57 which also operatesabout another sprocket wheel 58 on the shaft 16.

As intimated there is provided means for sprinkling the dirt in the compartment 53 and in reducing this feature of the invention to practice a tank 59 is mounted transversely on the dirt compartment and is designed for receiving suitable liquid such as water which is dispensed therefrom through the medium of a nozzle 60 depending from the tank. A door 61 is swingingly mounted in the back of the body and establishes access to the compartment 53 when it is desired to remove the dirt therefrom.

The mode of operation of the present invention may be reviewed as follows:

Assuming that the parts have been assembled in the manner described and as indicated in the drawings. Upon the forward movement of the vehicle rotary motion will be transmitted from the-rear axle 3 to the sweeping brush 17 so as to rotate the latter in the opposite direction and consequently assure of dirt, etc., being swept up the inclined apron'22 and deposited in the dirt trough 20. During this movement, the elevating meanscwhich is operably connected to the shaft 16- of the sweeping brush through the instruinentality of the sprocket 7 wheels 45 and 43 and the chain 4A as well as the stub shaft 42 and the inter-meshing gears 40 and 41, will be actuated so that the buckets 34 will be passed through the trough 20 so as to engage the dirt in the bottom thereof and elevate the dirt upwardly. These buckets are first tripped to assume the position as indicated in Fig. 3 by the tripping pin 37 so as to assure of a scraping of dirt from the trough and are subsequently tilted and tripped by the guiding shoe 38 and the tripping pin 39 so that the contents thereof will be deposited upon the inclined and endless conveyor and apron 51. As is apparent this apron operates simultane- Copies of this patient may be obtained for five cents each, by addressing th Washington, D. G.

that the language used in ously with the brush 17 and in the same direction so that the dirt will be conveyed upwardly and deposited in the dirt compartment 53. Suitable means, of course, not shown may be employed for actuating the sprinkling means so as to reduce the formation of dust when the machine is in operation.

It is believed in view of the foregoing description that a further detail description of the invention is entirely unnecessary.

Likewise it will be believed that the advantages of the invention will be readily apparent.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limited sense. It is also to be understood the following claims is intended to cover all the generic and specific features of the invention-herein described and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

The invention having been described, what is claimed as new and useful is:

A street cleaning machine including a vehicle body, a dirt trough formed in the bottom thereof formed near the forward end, a boot mounted near one end of the trough, a dirt compartment near the rear part of the body, brushing and sweeping means for depositing dirt in the trough, elevating means operably mounted in the body and passing through the trough and embodying a plurality of shafts arranged near the upper and lower corners of thebody, spaced sprocket wheels carried by the shafts, endless chains operating about the alining sprocket wheels, a series of buckets V-shaped in cross section having their ends swingingly connected to opposed links of the chains and normally positioned upright and between the chains, a trip member mounted in the body and designed to tilt each of the buckets as they successively enter the trough so as to facilitate filling of the buckets, a guide mounted near the top of the body for dumping the buckets, another trip member cooperating with the guide for assuring of the successive dumping of the buckets, and conveying means operably mounted in the body for receiving dirt from the buckets and depositing it in the dirt compartment.
