To all whom it may concern:

Be it known that I. Enxns'r DE LA SHA- LERI, a citizen of the United States, residing at Pittsburg. in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Street-Cleaning Machines, of which the following is 'a specification.

The present invention comprises a machinedesigned particularly for cleaning streets.

. The machine embodies a suitable truck adapted to be drawn by horses or other draft animals, or to be propelled by means of a motor, mechanism-being provided for loading material scraped or swept from a street intothe body of the vehicle and other mechanismbeing utilized to spread and pack the material as it is elevated and deposited in the vehicle body.

The invention also includes special devices for spreading the material, in the operation of the machineas above described, and pe culiar means for adjusting the latter device whereby, under certain conditions, they may be employed for the purpose of facilitating unloading of the vehicle.

Another feature of the invention resides in the special means employed for remov ing dirt, snow, or other foreign matter from the street and elevating it for deposition in the body of the vehicle. 7

For a full understanding of the present invention referenceis to be had tothe following detail, description, claims and drawings wherei'n- Figure 1 is a top planview of a machine embodying the essential features of the present invention, a certain portion of the top of the machme being shown insect on; Fig. 2 is a side elevat on of the same; Fig. 3-

Throughout the following description and on the several figures of the drawings. similar parts are referred to. by like reference characters. Specifically describing the invention and referring .to the drawings, 1 denotes the body of the machine which may be ofany suitable type built with a View of containing material, such as snow, dirt, or other foreign matter that may be gathered from streets or similar places. The body 1- is mounted upon suitable trucks and ground wheels 2 and, as above mentioned, the machine may be propelled by a motor, as shown, or pulled by draft animals, if desired.

At the front end of the machine is mounted an elevator in the form of a suitable carrier 3 supported upon a frame frigidly secured to the body 1;

Pivoted to the lower end of the elevator t at "5 is a scraper 6 consisting of a suitable frame equipped atits frontend with a scraping blade 7, the latter being adapted to- I Under some conditionsit may be desired to provide the scraper'6 with a sweeper or brush 13 and the latter is secured just in advance of the scraping-blade otherwise securely fastened to suitable fixtures at the front portion of the. scraper.

The scraper 6 is supported, when in its operative position-by the yieldably monntby meansof the frame parts 1 1 which are bolted or 106 link 12v with the frame orbody of the scraper 6.

ed wheels15 the latter being jonrnaled di-- 16 supported in guides 17 attached to opposite sides of the scraper t3. Springs are so arranged at opposite sides of the scraper 6 as to cooperate with the bars 16" to resiliently or yieldablv support the wheels 15. thus affording a resilient mounting" so to speak. for the scraper 6 permitting the latter. to accommodate itself to any unevenness in the surface over which the machine pa se there y increasing its. etliciency.

It will be apparent that the. material carried upward from the street or other surface beingcleaned by means of the elevator 3 willhe dumped into the body 1 of the mat chine. In order to spread this material as it is dumped into the body 1; special means. are employed and the same will now be described. l d'ounted upon a shaft 19 supported in snilable bearings and arranged transversely on the body 1 are driving wheels 20, The shaft 19 is driven bya motor 21 or any equivalent means. said motor being connected bv the driving belts or chains 22 and with driving sprocket or gear 2-1 on the shaft 19. The carrier 8 on the scraper 6 is likewise driven by the motor 21. one of the shafts about which the member 8 pas es being connected by a suitable drivingchain 25 to the shaft 19. The driving wheels 20 are connected by pitman rods 26 to lateral arms 27 projecting outwardly from the sides of a U-shaped spreader frame 28. The spreader frame 28 is arranged intermediate the ends of the body 1. and extends trans versely across the latter, as shown 'vmost clearly in the drawings. The sides 28 of the spreader. frame are connected for' ertical sliding movement on the sliding guides. 29, the latter consisting of inverted T-shaped members. the horizontal portions of which carry rollersEO and the vertical portions of.

which are channeled to receive th sides 28" of the spreader 28 and permit vcrt cal movement of the spreader frame with respect to the guides 29 and the body 1.

'are adapted to operate in the horizontal guides 31 secured to the opposite machine. The lateral arms 27 of the spreader frame are not only connected with the pitman rods 26 but the outer ends of said arms have rollers mounted rcon. r latter rollers operating in, the enoteiv v 33. The guides are arranged at opposi. sides of the body 1 and supported by suitable brackets secured to the body 1. ho

:spreader frame 28 supports a plurality of spreading devices the latter being carried by the parallel. bars 36. The bars 36 are pivotally connected at adjacent ends to i the sides of the spreader frame, the outer most ends of the bars 36 having the outer most Spreaders pivotally secured thereto,

and the intermediate spreader 35 being can I The rollers sides of the.

' is swiveled upoirthe intermediate portion of a the spreader frame 98. i

in rotating the same. Secured tothc intermediate spreader are horizontal lifting bars 39, the intermediate portions of which are connected to said ihtermediate spreader, one end of each bar 30 being attached to the rea'rmost spreader. Theiront .ends of the bars 39 extend through brackets 35 carried by the foremost front spreader 35. said.

damage to the smeaders'anay be avoided. For the abovepurpose the bars 31} connecting the outermost spreaders with the spreader frame 28 may be made insections, having the guidingsprings'at). in like manner the intermediate spreader-35 has yield- 1 ing rods 41 connecting it to the bar c From lthe foregoing it will'b'e understood.

that when'the machine is in actual operation the material l aded into the. body 1 by means of the elevator 'and other mechm nism located at the front end of the machine. lVhen the motor 21' is in operation the driving wheels will be operated o as to reciprocate the spreader frame back and torth with respect to the guides A the spreader frame moves toward the rear end of the endless guides the rollers mean-- while traveling in said guide; 3. springs 42 arranged near ,the rear ends ot the guid...s 33 will engage the arms '27 of the. s: wlfer frame and raise the latter to cause the rollguides 33 as the spreader frame i pulled upwardly by the pitman rods 1'26. ll'hen the spreader frame reaches the front limit oi? its movement with respect to the guides by reason of the shape of the latter guides, the spreading devices are permitted .to drop ried by a vertical adjusting screw 57 which lcaded into the body 1. whereby breakage or (ii-s39 to 'travel in the upper portions of? the a by a gradual downward and rearwt'u'd 1 during said forward movement. The ad- At. its upper end the screw 37 has a handle. 38 for convenience brackets affording a sliding connect-ion be- I adjustability of the spreader frame 28, the" spreading devices may be utilized to faeilitate the unloading of the bodyl by forc ing the material collected therein outwardly from the rear end of the body. 'v It is to be understood that the body 1 may be provided with any suitable-means for-facilitating the dumping or unloading of the material carried therein, any of the ordinary types of dumping mechanisms used on dumping vehicles being susceptible of use along the above lines.

Itis to be understood that the specific arrangement and construction of parts hereinbefore described, and appertaining to the several mechanisms set forth, may be varied within the spirit of thminvention and the scope of the appended claims.
