Specification of Letters Patent. I Patentgfi Jam, 1'3, 3911, A plication filed April 10, 1909.

Serial No. 489,208.

To all whom it may concern:

Be it known that I, JOHN B. nHoMnnoUn, a resident of Pittsburg, in the county of Allegheny and State of Pennsylvania, have in vented a new and useful Improvement in Street-Cleaning Machines; and I do hercbv "declare the following to be a full, clear, and

exact description thereof.

My invention relates to street cleaning machines, and has special reference to such machines for use in scraping or sweeping snow, dirt, etc, from streets, roads, highways, ctc.

The object-of my invention isto provide a cheap, simple and eflicient street cleaning machine which will scrape or sweep the snow, dirt and other matter from the street or other place on which it is used into the same to be carried thereby, as well as one which can discharge such snow or dirt therefrom into vehicles, such as wagons, carts, etc., for being hauled'away to a suitable point for dumping or any other purpose dcsired.

To these ends my invention consists, generally stated, in the novel arrangement, coustruction and combination of parts, as hereinaftermore specifically set forth and de scribed, and particularly pointed out in the claims.

To enable others skilled in the artto which my invention appertains to construct and use my improved street cleaning machine, I will describe the same more fully, referring to the accompanying drawing, in which- Figure l is a longitudinal section of my improved street cleaning machine, showing some of the parts in full lines. Fig. 2 is a top plan view of the front portion of the machine, with some of the parts removed. Fig. 3 is a cross-section on the line 33 Fig. 1, looking in the direction of the arrow.

Like symbols of reference herein indicate like parts in each of the figures of the drawing. V

As illustrated in the drawing, my improved street cleaning machine is shown as applied to a motor vehicle by being mounted upon the frame 1 of the same, and uponsaid frame is the receptacle or body 2 having the inclined front and rear ends 3 and 4, respectively. A shaft 5 is mounted in the upper portion of the front end 3 on the body 21, and around this shaft and a shaft 6 below the frame 1 is an elevator or conveyor 7, which is in the form of an ordinary endless belt 8 having the buckets 9 extending out from the same. he endless belt 8 is locatedwithin a casing 10 which extends around the shafts and 6 and is provided with a hood 10 at the upper end of the same for extending over the upper end of the belt 8 and shaft 5 and opening into the body 2. The belt 8 and casing 10 form the conveyor 7 an'dare mounted at a downward and outward angle toward the front of the'vehicle, so as to 'enable the same to be swung on the shaft 5 to the position desired through an opening 1.1 in theframe 1. This movement is accomplished by means of a pinion 11 (shown in dotted lines, Fig. 1) mounted on the shaft 6 and engaging with a rack 12 on a bracket 13, which is connected to and extends below the frame 1. The lower end of the conveyor 7 is adj usted to the inclination desired on the bracket 13 by means of a crank lever or handle let mounted on the shaft (5, and by turning the same acts to move the pinion 11 along the rack 12, and the position of conveyor is then set by means of a paw 15 mounted on said shaft and engaging with said rack.

Hung from the lower end of the conveyer casing 10, is the scraping device 16, which is preferably of the same construction as shown in my application filed September 9, 1908, Serial No. 52,191, and it consists generally of an inclined trough 17 having a series of scrapers 18 pivoted flexibly to the forward end of the same. This trough. 17 leads into the conveyor 7 at its upper end through an opening 19 in the lower end of the con veyer casing 10 and it is hinged to said casing as at 20, so as to extend at a downward and outwz rd angle toward the front of the vehicle and adjust itself to the position of the said conveyer. v

Pivotally hung from a shaft 21 at the forward end of the vehicle through the frame 22 is the sweeping device 22, which is adapted to be raised and lowered on said shaft in the usual manner, and preferably consists of a central cross broom 23 and outside brooms 25. The broom 23 is mounted on a shaft 24; extending across and journaled in the frame 22, and the outside brooms 25 are mounted on shafts 26 in; said frame and'ex tend forward and outward at. an angle on each side of said central broom 23. v A pin-' ion 27 is mounted on the shaft 24 and on each end of the broom 23 for engaging with a pinion 28 mounted on each of the shafts 26'and on the inner end of the brooms 25.

An engine or motor 29 is mounted on the frame 1 and the shaft 30 of the same has a pinion 31 mounted thereon for meshing with a gear wheel 32 mounted on a shaft 33,

5 for operating the belt 8 of the conveyer 7.

Located in the bottom of the body 2 is the conveyer 43, which is formed of an endless belt 01' apron 44 passing around roller shafts 45 at each end of the same, and journaled in the sides of the saidbed. The apron 44 has its upper portion supported by the idlers 46, which are positioned'within the belt 44 and under the said portion and are mounted in the sides of said bed. The apron is positively driven by means of sprocket-chains (not shown) and passing over sprocketwheels 47 on each end of the shafts 45. The

front shaft 45 of the conveyer 43 has a sprocket-wheel 47 on one end of the same, and a sprocket-chain 48 passes around the same and around a sprocket-wheel 48 on oneend of the engine shaft 30 for operating said conveyer. Guides 49 having inclined sides 50 are secured to the sides of the body 2 and extend from said sides out to the side edges of the conveyer apron 44 for directing the material onto said apron.

Extending upward and outward from the rear end of the conveyer 43 and within the body L2 is the conveyer or elevator 51, which is fo'med of the endless belt 52 passing around shafts53 mounted in the upper and lower portions of said bed and, is provided with the buckets 52 thereon. The upper end of the belt 52 leads into a hood 2 formed on the rear of the body 2, and the upper shaft53 at said end'is provided with a sprocket-wheel 53 having a sprocket-chain 54 passing around the same and around a sprocket-wheel 55 on the engine shaft 30 for operating the conveyer or elevator 51.

I A clutch 56 (shown in dotted lines, Fig. 1) is mounted on th engine shaft 30 and is controlled by the clutch lever 57 for operating the conveyor 7 and sweeping device 22 separately or together, as desired, and a clutch (not shown) is mounted on said shaft WW A, A

sprocket-wheel 34 on and controlled by a clutch lever 58 for operating the conveyer 43 and elevator 51 at different times, or both at the same time, as

may be desired.

The operation of my improved street cleaning machine 15 as follows.

The machine can be propelled by the engine or motor 29 through any suitable connections, or by a separate engine or motor, as desired, and with the conveyer 7 and sweeping devices 22' operated from said engine 29, as described, the snow, dirt or other material on the street will be swept into a windrow in front of the central sweeper 23 through the outside brooms 25 and by reason of said brooms 25 being revolved away from the machine as it moves ahead. The central broom 25 being revolved in the opposite directionfrom the brooms 25 will turn to ward the machine and sweep the material of the windrow toward the scrapers 18 and trough 17, where it is caught by said scrapers and trough and passes up the same to the-conveyer 7 through the opening 19 in the casing 10 of the same. hen the material'reaehes tilt conveyer 7 it will be carried up the same through the belt 8 and its buckets and delivered into the body 2, where it falls or slides down the front end 3 of said body and onto the conveyer 43. As the conveyer 43 and elevator 51 are operated from the engine 29, as before described, the material so delivered onto said conveyer will be carried to the elevator 51 on the apron 44 of such conveyer and such elevator will carry the said material from said conveyer up the same by the belt 52 and buckets 52 and discharge the same into a wagon, cart or otherreceptacle, as shown at a in Fig. 1. It will be obvious that the conveyer 7 will deliver the material into the forward end of the body 2 and onto the conveyer 43, so that the said conveyer can be operated by the lever 58 to move the said material backward on the same to permit more material to enter said body, and when the body has become filled the elevator 51 can be operated to discharge the material from saidbody and conveyer while said conveyer is in operation or at a different time through the clutch lever 58.

At the forward end of the machine, and as shown in Fig. 1, the usual parts of a motor vehicle are provided, such as the radiator 59 and-operatoflsseat- 59, adjacent to which are the usual steering and operating devices (50 for the vehicle, and from which L the different mechanisms connected tothe engine 29 can be controlled or a separate engine or motor for operating the vehicle, or both, as desired.

It will street cleaning machine will provide for the rapid and easy cleaning of the street, and the material gathered from the street .can

bus be seen that my improved veniently.

It will also be evident that my improved street cleaning machine can be usedwithout forming part of a motor vehicle, and that the same can be used with the scraping devices without the sweeping devices or with the sweeping devices and without the scraping devices, and various othermodifications and changes in the construction and operation or design of the machine may be resorted to without de'partin from the spirit of the invention, or sacrificing any of its advantages. i

The machine can be used to automatically gather, collect and discharge snow, dirt and other material from streets, roads, highways, pavements, sidewalks and other places, and the parts of the same can be mounted on any suitable vehicle and moved by horses or other suitable power. By the use of the machine in cities, the streets, alleys, pavements, highways, etc, can have the snow, dirt or other material removed therefrom in'a very short space of time and without the employment of a great number of men and wagons or carts usually engaged in such work, thereby greatly cheapenmg the cost for this kind of work and enabling trafiic and comfort to be had rapidly and con- What I claim as m invention and desire to secure by Letters atent, is
