Be it known that I, PETER SHANNON, a ci tizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hydraulic Street Cleaning Apparatus, of which the following is a specification. i

The present invention relates to asystem of cleaning city streets by the forcible discharge of a stream of water over the surface of the same, and has for its primary object toprovide a simple and efficient arrangement of apparatus in which the lead of hose employed in the operation of washing or iiushing the street is automatically unwound with the progress of the operation of washing a predetermined length of the street and subsequently rewound with a completion of the operation of Washing such length of street ready to begin the washing or flushing operation upon the next length of street and in connection with such mode of operation to eect a discharge of water through the lead of hose with the required force to attain a rapid and effective cleaning of the street.

A secondary object of the present invention is to provide means whereby the hose can be maintained in a condition filled with water during the operation of winding the same uponits carrying-reel in order that the flow of Water will not be interrupted in a subsequent use of the hose during the street-washing operation and While the hose is wholly or partly wound upon such carrying-reel, all as will hereinafter more fully appear and be more particularly pointed out in the claims.

I attain such objects by the construction and arrangement of parts illustrated in the accompanying drawings, in which- Figure l is a side elevation of the reel and truck of the present invention; Fig. '2, a plan view of the saine; Fig. 3, a rear end elevation of the same; Fig. 4, a side elevation of a portable auxiliary pumping-engine for use in connection with the present apparatus; Fig. 5, a fragmentary sectional plan view of the same at line at Fig. 4; Fig. 6, a dia' gramniatic view illustrating the electromag-- netic controlling mechanism for the throttlevalve of the auxiliary pumping-engine; Fig. 7, an enlarged fragmentary sectional elevation of the detachable connection between the hose and the auxiliary pumping-engine and illustrating the electric mains by means of which such pumping-engine is governed; Fig. 8, a similar view of the connection between the carrying-reel and the hose; Fig. 9, a detail cross-section at line m m, Fig. 8; Fig. 10, a detail plan view of the automatic guide mechanism for the hose in the reeling and unreeling of the same; Fig. ll, a transverse section of the same at line :r2 x2, Fig. l0; Fig. l2, an enlarged detail transverse section on line 9:3 m3, illustrating the auxiliary governing mechanism of the guide mechanism aforesaid.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents a truck of any usual and approved construction, provided with the usual wheels and steering-gear, as usual in hose-trucks and the like.

2 is a hose-reel journaled by means of a tubular axle 3 in the journal-boxes l/ on the main frame 1 and provided with the usual end heads et. In the present invention such journal connections between the ends of the tubular axle and the respective journ al-boxes are made watertight by any usual and wellknown means which will permit of a turning movement of the tubular axle in the journalboxes.

5 represents duplicate fiexible hose-pipes connected to the outer ends of the respective journal-boxes 1, with their bores in commun nication with the bore of the tubular axle 3 and adapted to receive water therefrom.

6 represents discharge-nozzles on the free ends of the duplicato hose-pipes 5 aforesaid and adapted to afford. means whereby the workmen are enabled to handle the discharge ends of such hose-pipes and direct the issuing streams of water to different portions of the street-surface in the washing or flushing of the same.

7 is a comparatively long lead of hose, one end of which is adapted for attachment to the source of water-supply, as hereinafter more fully set fortlnwhile the other end is attached to a lateral neck 3 of the tubular axle 3, the arrangement being such that the said load of hose can be wound around said axle and conloo' 9 represents similar valves at the normally free end of the lead of hose 7 and which are adapted to shut off the discharge of water carried by the wheeled pump-truck 11.

therefrom. The arrangement and purpose of the aforesaid Valves S and 9 areito confine a filling of water within the hose lead 7, so that the same will maintain a cylindrical form when wound upon its reel, and'thus permit of water being forced through such hose while still in a reeled or partly-reeled condition in the progress of the operation of washing the street.

\Vith the present system of cleaning streets the ordinary city-main pressure does not afford a discharge of water forcible enough to effect a rapid and eiieient street-cleaning operation with the present type of apparatus and the long lead of hose employed therewith. Accordingly the present apparatus includes an auxiliary pumping-engine as a tender to the hose-truck heretofore described and which truck will be carried from place to place along with the hose-truck to be left at a water-plug or other source of water-supply from which it is adapted to pump the water from such source of supply and discharge the same through the heretofore-described hosereel and its discharge-nozzles 6 to effect the necessary washing operation upon a section of street or roadway.

l In the particular apparatus shown in Figs. 4 and 5 of the drawings as illustrative of such auxiliary pumping-engine, 10 is a suitable motor-engine driven in any usual manner from a suitable source of power-supply and which will usually be a steam-generator 12 is the throttle-valve otsuch engine, provided with an operating-lever 13, which in turn is connected to the armature 14 of an operating electromagnet or selenoid 15 for a purpose hereinafter set forth. l 16 is a fluid-pump of any usual and suitable construction, carried by the truck l1 and operated by the motorengine 10. 17'r4 is the water-inlet trunk for said pump 16, adapted for connection by a suitable hose with the water-plug or other source of water-supply. 1S is the water-outlet pipe' fromsaid pump, adapted for attachment to thel'ead of hose 7 of the hose-reel ,heretofore described.

The con'vlli'ent control of motor-engine 10 by thefoperatolrfnpon the main hose reel or truclcij attained' in the present invention by la constru':tir'-n'1r-{as follows; 19 is an electrical control-le' 'inl-.which may be arranged a series o f electriefbatteries affording the required "electric-powemv Suchcontroller is `of vany usual forinand'construction and is provided with an adjustable handleor lever 20, by means of which a current of any desired strength can be sent along the circuit of the present construction. 21 22 are the circuitwires, connected, as usual, to the said controller. Such wires extend to the pair of brushes 23 21 in contact with the insulated rings 25 26, which are arranged concentric with the hollow axle of the hose-reel 2, as illustrated in Fig. 8. 27 is a cable containing extensions of the circuit-wires' 21 and 22 in insulated relation, and which extensions are connected to the insulated rings 25- and 26. Such cable is arranged Within the bore of the lateral neck 3 ot' the same, and its wires are connected to the insulated binding-posts 28 and 29, arranged at the periphery of such lateral neck. 30 is a similar cable arranged Within the bore of the lead of hose 7, the wires of which at one end are adapted for attachment in a detachable manner to the binding-posts 23 and 29 aforesaid, While the other ends of the wires or conductors are adapted for attachment in like manner to the binding-posts 31 and 32 of a coupling head 33, by which such end of the lead of hose 7 is connected to the pump 16 of the auxiliary pumping-engine. From the binding-posts 31 and 32 conductor-wires extend to the operating-electromagnet 15, heretofore described, by which the throttle-valve 13 of the motor-engine 10 is governedA and controlled. Such connection between the lastmentioned conductor-wires may be effected by the usual plug 34. or other usual circuitmaking provision.

Vith the arrangement described the operator upon the hose truck or reel is enabled to conveniently1 govern the action of the auxiliary pumping-engineto suit the particular requirements met with in the progress ot' the work.

In order to lay the lead of hose 7 upon the reel 2 in a uniform mannerin the winding-up or reeling operation, any usual and suitable automatic guiding mechanism may be employed. In Figs. 1, 2, 3, 10, 11, and 12 I illustrate an automatic mechanism for such purpose, and in which 35 is a counter-shaft receiving positive rotation by gearing connection or otherl usual meansfrom one of the driving-wheels of truck 1 and carrying a driving-pulley 36, as shown in Fig. 1. 37 is an intermediate shaft journaled on the truckframe andgcarrying a pulley 38, which is connected bybelt'39 with the pulley 36 aforesaid. 40 isI aftightener-pulley havinglinkand-,lever connections, as shown in Fig. l, with an operating-lever -Ll adjacent to the operators seat or station on the main truck, the arrangement being Lsuch that the operator is enabled by means ofsuch tightener to either tighten the belt, so lthat both pulleys will revolve in unison, or to loosen such belt,

so that the intermediate pulley 38 will have no revolution on account of the slippage of the. belt thereon. 42 is a belt connecting a IOO las

pulley on the intermediate shaft 37 with a similar pulley on the hose-reel 2 and adapted to impart rotation thereto in unison with the rotation of such shaft S7, as before described. 43 is a traversing carriage, arranged to move back and forth across the rear end of the hose-.reel2 and provided with a grooved guide wheel or sheave 44,.adapted to receive and guide the hose onto the reel. 45 is an endless chain-connected to said carriage and passing over carrying-pulleys 4G at the respectiveA sides of the truck-frame 1. 47 is a longitudinal counter-shaft carrying at one end a pinion 48, adapted to have operative engagement with a side flange or head of the reel 2, and at its other enda pinion 49, which meshes with and drives a gear-wheel 50, earried by a crank-shaft 51, as shown in Fig. 10. 52 is a crank-shaft arranged at the opposite side of the truck-frame to that at which the -crank-shaft 51 is arranged and operatively connected thereto by the connecting-rod or pitman 53 engaging the respective cranks of the two shafts. A

In the construction shown the crank-shaft 52 carries one of the chain-pulleys 4G, while the other crank-shaft 51 is independent of the other chain-pulley at the same side of the truck-frame. s p

54 is a seconday crank on the crank-shaft 52 and adapted in connection with themeehanism hereinafter described to reverse theV direction of the movement imparted by the crank-shaft 51 to the crank-shaft 52 at the will of the operator, as well as automatically, in a continued reeling or winding up of the hose upon the hose-reel.

55 is a rocking member arranged adjacent to the secondary crank 54 aforesaid and provided at its respective ends with hook-shaped ends 56, which are adapted to be alternately moved into the path of the crank 54 to engage said crank to hold the same from further movement in the direction in 'which it had previously'traveled. lith such holding of the crank54 as described the other crank of the crank-shaft 51 will pass its dead-center, and its further movement will impart motion to the secondary crank 54 and its shaft 52 in a direction opposite to that in which the same had previously moved.

57 and 58 are spring-dogs engaging ratchetteeth on the opposite sides of the rocking members 55 and adapted to hold the same fixedly in position when one or the other of said dogs is not moved out of active engagement with the ratchet-teeth of such rocking member.

59 is a rock-shaft extending longitudinally of the truck from the operators station toA adjacent relation to the aforesaid spring-dogs 57 and 58 and provided with a rocking head or cross-arm G0, the respective ends of which are adapted to alternatelyfengage against said spring-dogs to move the same away from` their engagement with the rocking members 55 at the will of the operator.

The rocking member is mounted centrally on an operating-shaft 61, which extends to a position adjacent to the operator, so as to enable tion by hand when circumstances so require or as his judgment may suggest.

ln the present construction as shown in the drawings the described reversing operation is also effectedin an automatic manner by the following-described mechanisms: G2 is a bell-crank lever, one end of which has operative engagement with one of the springdogs aforesaid, while its other end is arranged in the path of the traversing carriage 43 and adapted to be operated by the same as such carriage nears one end of the main reel. 3y this means the rocking member 55 is released from such dog, so that a further movement of the carriage 43 will by direct engagement with one end of said rocking member move or rock the same,`so thatY the hook 5G at the opposite end ofthe rocking member will be moved into the path of the secondary crank 54, in the manner hereinbefore described, to cause a reversal in the direction of the movement of such traversing carriage. G3 is an arm carried by a shaft or rod 64 and adapted to have operative engagement with the other of the spring-dogs aforesaid in manner similar to the bell-crank lever 62. The shaft 64 extends transversely across the main-truck 1 and at its end is connefted to one end of a lever 65, the other end of which is arranged in the path of the traversing carriage 43 and is adapted to be operated by the same as said carriage nears the end of its movement in a direction toward said lever. By such means the rocking member 55 is released from the last-mentioned spring-dog, and a further movement of the carriage 43 will through the shaft 64 impart a rocking movement to said member 55, so that the other hook 5d will be moved into the path ofthe secondary crank 5.4 to eeet in the manner hereinbefore described a reversal in the direction of the movement of such traversing carriage. 1
