SE LF-LOADING CART.

To all whom it may concern.-

Be it known that 1, ROBERT CHARLES MEN- miss, a citizen of the United States, residing at Glens Falls, in the county of Warren and State of New York, have invented a new and useful Self-Loading Cart, of which the following is a specification.

This invention relates to street cleaning devices; and it has among its objects to provide a device of this class which shall be simple in construction, durable, and efficient in operation.

Among the special objects of the invention are the production of an organized machine in which means for gathering and collecting the dirt or refuse shall be mounted upon a wheel-supported frame in connection with a receptacle into which the refuse may be emptied from time to time, said wheel-supported frame affording also a seat for an operator, who by pedaling causes the machine to be propelled over the ground and supplies the motive power needed for the operation of movable members of the device.

A further object of the invention is to provide an improved dirt-receiver and means for elevating the same, so as to cause it to be emptied into the receptacle which is carried by the machine.

A further object of the invention is to provide an improved conveyer pan or guide adapted to cooperate with the receiver.

A further object is to provide resilient supporting means for the free edge of the conveyer-pan.

Further objects of the invention relate to improvements in the detailed parts or members of the device.

With these and other ends in view, which will readily appear as the nature of the-in vention is better understood, the same con sists in the improved construction and novel arrangement and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being understood that no limitation is necessarily made to the precise structural details therein exhibited, but that the right is reserved to any changes, alterations, and modifications which come fairly within the scope of the invention and which may be resorted to without departing from the spirit or sacrificing any of the advantages of the same.

Specification of Letters Patent.

Application filed June 6, 1904. Serial No. 211,424.

Patented Jan. 23, 1906.

In said drawings, Figure 1 is a perspective view of a street-cleaning device constructed in accordance with the principles of the invention. Fig. 2 is a side elevation of the same. Fig. 3 is a rear elevation. Fig. 4 is a detail top plan view.

Corresponding parts in the several figures are indicated by similar numerals of reference.

The frame of this improved machine in chides a tubular bearing 1, in which is journaled the front fork 2, affording bearings for the axle of a light wheel 3, which is preferably rubber-tired and of ordinary bicycle construction. The upper end of the front fork carries a handle-bar 4, by means of which the machine may be steered, as will be readily understood.

Extending rearwardly from the tubular bearing 1 are the side frame-bars 5 and 6, whichfor the sake of combining lightness and strength are preferably of tubular construction. The side bar 5, which I term the inner side bar, is approximately straight and is extended in a rearward direction, terminating at its rear end in downwardly-extending fork members 7 and 8, having bearings for the spindle 9 of the rear wheel 10, which is disposed approximately in the same vertical plane as the front or guiding wheel 3.

The outer side bar 6 is provided with offset portions or curves whereby its rear end is considerably spaced apart from the rear end of the inner side bar 5. The rear end of said outer side bar is provided with downwardlyextending fork members 11 and 12, affording bearings for the spindle 13, carrying the rear supporting-wheel 14, which is in axial alinement with the rear supporting-wheel 10, the spindles 9 and 13 being connected by means of a shaft 15. A cross-bar 16 connects the upper ends of the fork members 7 S and 11 12, and suitably-disposed brace members are to be employed for the purpose of strengthening the frame structure wherever needed. The inner side bar 5 also supports a seat 17 and a downwardly-extending arm or bracket 18, provided at its lower end with a bearing for a crank-shaft 19, the cranks of which are provided with pedals 20. The crank-shaft 19 carries a sprocket-wheel 21, connected by a chain 22 with a sprocket-wheel 23 upon the hub of the driving-wheel 10, to which motion may thus be transmitted, as will be readily understood.

The inner and outer side bars 5 and 6 of the frame are connected near their rear ends by a cross-bar 24, provided with upturned ends 25, which rest and are supported upon the upper sides of the side bars and are connected with the latter by means of verticallydisposed bolts or in any other suitable and convenient manner. Suitably connected with and supported by the cross-bar 24 are a pair of downwardly-extending straps or hangers 26, terminating at their lower ends in approximately horizontal supports or stirrups 27, having offsets 28 and. provided with upturned rear ends 29. These hangers are preferably constructed of flat straps of metal of suitable dimensions, and the upturned portions of the rear ends 29 of the stirrups are connected by a cross-bar 30, which may be secured by means of bolts or rivets and the ends of which are bent upwardly, so as to form the arms 31 of a yoke of which the member 30 is the cross-bar. The arms 31 are bent in a vertical plane, as will be clearly seen in Fig. 2 of the drawings, so that they may be described as extending upwardly and forwardly from the points at which they are connected with the front ends of the stirrups 27 and thence upwardly to the side bars 5 6 of the frame with which they are connected and whereby they are firmly supported.

The cage or structure, comprising the hangers 26, stirrups 27, cross-bar 30, and arms 31, is for the purpose of supporting the dust-receiver 32, which consists of a suitablyconstructed approximately rectangular box, which may be appropriately made of galvanized iron or other sheet metal suitably protected against corrosion. The bottom 33 of this receiver is rounded at its front and rear portions, the rear portion. of said bottom being extended beyond the box, so as to form a lip 34, appearing in dotted lines in Fig. 2, and which when the receiver is in operative position is supported upon the cross-bar 30. The rear side of the box 32 is entirely open for the reception of sweepings. The end pieces 35 of the box increase in height in the direction of their front portions, and they ser ve to support a lid 36, which is hinged between the up per rear corners of the end pieces. The rear edge of the lid or the rod which hingedly supports said lid is provided with a guard-strip 37 of rubber, felt, or other suitable material, which when the receiver 32 is in operative position abuts upon the front side of the brushcasing, which will be hereinafter described, said strip performing the double function of steadying the receiver 32, so as to prevent rattling and of preventing the escape of dust upwardly in front of the brush-casing between the latter and the receiver 32.

38 designates the brush-casing, which is in the nature of a curved, partly cylindrical shield, having end pieces 39 and containing a cylindrical rotary brush 40, which is mounted upon a shaft or axle 41, the ends of which project through segmental slots 42 in the ends of the casing. The brush carrying shaft 41 is journaled in a pair of rocker-arms 43, the opposite ends of which are pivotally mounted upon the shaft 15, with which the slots 42 are concentric. The brush-casing is connected with the shaft 15 by means of clips, as best seen at 44, in Fig. 1 of the draw ings. Additional supporting means for the brush-casing are in the nature of chains 45, which connect said casing with hooks 46 upon the frame of the machine.

The dust-receiver 32 is provided near the ends thereof with reinforcing straps or bands 47, which coincide with the supporting-hangers 26 and which may be described as forming shoes engaging said hangers when the receiver 32 is slid or moved upwardly for the purpose of discharging its contents into a receptacle provided for the purpose or when it is moved downwardly into its normal position upon the stirrups 27. The upward and downward movement of the receiver 32 is effected by means of a yoke 48, the ends of the arms of which have pivotal connection with pins 49, extending from the ends of the receiver. The arms of the yoke, at the point where they meet each other, are quartertwisted and cooperate to form an arm 50.

51 designates a shaft which is journaled in bearings upon a portion of the outer side bar 6 of the frame, said portion of the side bar being disposed approximately parallel to the shaft 15. The ends of the shaft 51 are bent at angles to the body of the shaft, thus forming arms 52, which converge at 53, so as to form the side members of an approximately triangular frame, of which the shaft 51 is the base. From the apex 53 of this frame the arms or side members 52 are extended in the direction of the arm of the yoke 48, with which they are pivotally connected, as indicated at 54.

Rigidly connected with the triangular frame, of which the rock-shaft 51 is the base, is an operating-lever 55, having a pivoted handle member 56, which is connected, by means of a rod or member 57, with one arm a bell-crank 58, fulcrumed upon the extended ends of the side pieces 52. The free end of the bell-crank 58 terminates in a hook or ratchet member 59, which when the dust-receiver 32 is in a lowered or operative position, as shown in Fig. 2, automatically engages under the crossbar 24, thus positively preventing displacement in an upward direction of the dust-receiver 32 and related parts. When the dust-receiver is in this position, the operating-lever will be elevated, as best seen in Fig. 2, to a convenient position accessible to the operator who occupies the seat 17. When it shall be desired to elevate the dust-receiver to the position shown in Fig. 1, the operator grasps the handle portion of the lever 55, thus actuating the pivoted grip portion 56, and through the latter and the rod 57 the bell-crank 58, having the catch 59, which is thus released from the cross-bar 24, thereby permitting the lever 55 to be moved in a downward direction, so as to elevate the dust-receiver, as will be readily understood.

For the purpose of assisting in raising the weight of the dust-receiver a spring 60 is provided, a portion of said spring being wound upon the shaft 51, so as to form two coils or helices and a central depending tongue 61, which is inserted under the portion of the frame -bar 6 upon which the shaft 51 is mounted. The ends of the spring 60 are suitably extended and connected with the apex 53 of the approximately triangular frame formed by the shaft 51 and side members 52. It is obvious that the tension of this spring will be exerted to assist in overcoming the weight of the receiver 32 when the latter is to be elevated. At the same time it is not intended that the tension of this spring should be sufliciently great to prevent the weight of the receiver from restoring it by gravity to its normal operative position.

The bearings in which the shaft 51 is mounted upon the frame-bar 6 are in the nature of blocks 62, each having an upper and a lower concave side, engaging, respectively, the frame member 6 and the shaft 51, for which latter the said blocks form half-boxes. The boxes or bearings are completed by means of clips 63, which include between them the shaft 51, the blocks 62, and the frame member 6, all of which are thus firmly united, but in such a manner as to permit the shaft 51 to rock freely in its bearings in the manner and for the purposes herein indicated The hangers 26, which, as hereinbefore described, are supported at their upper ends upon the cross-bar 24, are extended in front of said crossbar, so as to form arms or brackets 64, through which extends a rock-shaft 65,

- provided at the ends thereof with rearwardlyextending crank-arms 66, having hooks 67 at the extremities thereof. These hooks are normally forced in a downward and a rearward direction by the action of springs 68, suitably wound upon the rock-shaft and having their ends in contact, respectively, with the fixed bearings 64 and with the movable hook members, as will be readily understood. Upon the ends of the dust-receiver 32 are provided laterally extending pins 69, which when the dust-receiver is elevated by the means herein described will contact with the hooks 67, whereby the hooks will be tilted upwardly as the dust-receiver continues its upward movement, while at the same time the said dust-receiver by the action of said hooks will be tilted upon its pivots to the position indicated in Fig. 1 of the drawings, by reference to which it will be seen that the open rear side of said receiver is uppermost, while the lid 36 will swing open and cause the contents of the receiver to dump into a receptacle provided therefor. When the receiver is lowered,,the hook members 67 will be caused by the tension of the springs 68 to be automatically restored to their normal position, causing the dust-receiver likewise to be tilted into its normal position while in the act of being lowered. Then it nearly reaches its lowermost limit, the box will be pressed in a rearward direction by the shoulders or offsets 28 upon the hangers, thus forcing it to occupy the precise position with relation to the refuse-gathering mechanism which it is intended that it shall occupy.

The refuse-receptacle may be and is preferably in the nature of a can 70, of galvanized iron or other suitable material, which is supported upon hangers or bracket members 71, depending from the frame of the machine and which, each of said brackets being suitably located and connected with the remaining ones, cooperate to form a convenient support for the can 70, which latter, however, may be readily removed by simply lifting or tilting it off the support afforded by said brackets. Two of the latter are connected by means of a chain 72, which is permanently connected to either of said brackets and detachably connected with the other, for instance, by means of a hook and staple 73 and 74. This chain is simply for the purpose of retaining the refuse-receptacle securely in position during the operation of the machine and in such a manner that when it has become filled it may be quickly and conveniently removed and an empty one substituted in its place. It is obvious that any other well-known and approved means may be used for the purpose of detachably supporting the refuse-receptacle in its proper position. The latter is also preferably provided with handles, as 74, by means of which it may be conveniently manipulated.

For the purpose of directing the refuse from the receiver 32 into the receptacle I avail myself of a pair of hopper-shaped chutes 75, which are mounted in and suitably connected with loops 76, formed upon a support ing-rod 77, the rcarwardly-extending ends of which are suitably connected with the crossbar 24, said ends being arched so as not to interfere with the rock-shaft 65 or related parts. The front portion of the supportingrod 77 is adapted to rest upon one or both of the clip-plates 78 of the clips 63, hereinbefore described. By these hoppers or chutes, which are disposed transversely with relation to the machine and the upper edges of which are spaced sufliciently apart to receive the material discharged from the receiving-box 32 when the latter is elevated and tilted, as hereinbefore described, the refuse will be directed into the receptacle placed underneath without the least danger of spilling any portion thereof. The rearward-extending ends of the supporting-rods 77 are coiled upon or otherwise hingedly connected with the crossbar 24, so that when it shall be desired to remove the can or receptacle from its supports the hopper-carrying frame may be swung back to a position indicated in. dotted lines in Fig. 2 of the drawings.

When it shall be desired in place of the metal can to use an ordinary gunny sack as a receptacle for the refuse collected by the machine, I prefer to avail myself of a bagsupporting ring 79, (shown in Fig. 4 of the drawings,) said ring being provided with a hook member 80, adapted to engage the cross-bar 24, the opposite side of the said ring being permitted to rest upon one or both of the clip-plates 78. This bag-supporting ring will be preferably provided with hooks, as 81, or other convenient and approved means whereby a bag may be supported in position and which will permit such bag to e conveniently applied or removed, as may be desired.

It has already been stated that by the use of this machine refuse is gathered by the cylindrical brush 40, which is mounted upon the shaft 41, journaled in the free ends of arms or levers 43, fulcrumed upon the shaft 15. Rotary motion is conveyed to said brush from the driven rear wheel 10 of the machine. The mode of and means for transmitting motion and of throwing the cylindrical brush into or out of gear, as required, are as follows: The wheels 10 and 14 are both mounted to rotate freely upon their respective spindles. The hub of the wheel 10 carries the sprocket-wheel 23, whereby it is connected, through the chain 22, with the directly-driven sprocket 21. The hubs of each of the wheels 10 and 14 carry disks 82, which are perforated for the reception of pins 83, extending from the hubs of gear-wheels 84, which are journaled upon the shaft 15 adjacent to the inner sides of the transportingwheels. The inner ends of the hubs of the gear-wheels 84 are annularly grooved and are engaged by the bifurcated ends of levers 85, which are fulcrumed at 86 upon the frame members 8 and 12 of the frame. It is obvious that by moving the lovers in the proper direction. the gear-wheels may be moved axially upon the shaft 15, causing the projecting pins 83 to pass into or out of engagement with the perforations in the disks 82, thereby locking the gear-wheels upon or unlocking them from the hubs of the transporting-wheels 10 and 14, as may be required. For the purpose of actuating the levers 85 additional short levers 87 are provided, said short levers being fulcrumed upon the frame membersS and 12 below the fulcra of the levers 85, with which the outer ends of the levers 87 are connected by means of links 88. The inner free ends of the levers 87 are pivotally connected with the lower ends of a pair of resilient operating-rods 89, which, for the purpose of inducing resiliency in the desired direction, are provided with loops 89 formed thereon. The rear crossbar 16 of the frame of the machine is provided with brackets 90, with which are pivotally connected the approximately horizontal arms 91 of a pair of bell-crank levers 92, the approximately vertical and longer arms 93 of which are connected with each other by a connecting-rod 94, said connecting-rod and levers cooperating to constitute a yoke. Pivotally connected with the cross-bar 94 is a forwardly-extending connecting-rod 95, the extended front end of which is connected pivotally with a lever 96, which is fulcrumed upon the inner side of the side bar 5 of the frame at the point indicated by 97 and which is provided with a crank or handle 98, by means of which it may be easily reached and manipulated by the operator, the lever 96 being disposed, as will be seen, in a convenient position between the drivers seat and the handle-bar of the device. The rod 95, near its point of connection with the lever 96, is slightly bent, as will be clearly seen in Fig. 2, so that by depressing the front end of the lever 96 the pivotal connecting-point of said lever and the connecting-rod will be thrown slightly past a dead-center, whereby the said connecting-rod and the parts oper ated thereby will be automatically retained in adjusted position. The rear ends of the horizontal arms of the bell-erank levers 92 are connected, by means of rods 99, with the arms 43, carrying the rotary brush member of the device. Said arms are connected, by means of chains 100, with the flanged edges of a conve'yer 101, which is in the nature of a pan provided with forwardly-extending ears or lugs 102, which are pivotally connected with the lower ends of the brackets 31, which in part support the dust-receiver, the front edge of the conveyer-pan 101 being normally supported upon the rearwardly-projecting lip 34 of the receiving-box 32, into which refuse will thus be guided over the said pan or conveyor, as will be readily understood. Secured transversely of the under sides of the stirrups 27, upon which the dust-receiveris practically supported, is a transverse bar 103, to which is secured the front edge of a plate 104 of resilient material, such as sheet-steel, said plate projecting under the conveyer-pan 101, the free end of which is partially supported upon said resilient plate. The under side of the conveyer-pan is reinforced by a transversely-disposed cross-bar 105, which, in the drawings has been shown as being L- shaped for the purpose of increasing the stiffness and rigidity of the pan. It will be seen that by operating the lever 96 in one direction, which is indicated by an arrow in Fig. 2 of the drawings, the bell-erank levers 92 will be rocked upon their fulcra, with the re- ITO sult that the resilient connecting-bars 89 will be depressed, thus causing the levers 87, through the links 88, to actuate the levers 85, thereby sliding the spur-wheels 84 outwardly upon the shaft upon which they are journaled andcausing them, by means of the pins 83 and disks 82, to become interlocked with the transporting-wheels 10 and 14, thus causing them to transmit motion to the rotary brush 40, the shaft of which is provided at the ends thereof with spur-wheels 106, intermeshing with the gear-wheels 84. At the same time the rotary brush member, which is carried by the arms 43, connected, b the rods 9.9 with the rear ends of the bell-crank levers 92, will be lowered into active or operative position in contact with the ground. Furthermore, and by the same operation, the free edge of the conveyer-pan, which is connected by the chain 100 with the link-bars 43, will be lowered for the purpose of receiving the refuse swept over it by the rotary action of the brush and guiding the same into the receiver 32.

The shaft 41, carrying the rotary brush member, is incidentally provided with a compensating gearing, (conventionally indicated in dotted lines at 107 in Fig. 3 of the drawings,) the object of this being simply to permit the machine to turn freely in any direction, as will be readily understood. This is an important feature of the device, for the reason that when the machine is thrown into operation both of the transporting-wheels 10 and 14 will become interlocked with the brush-operating mechanism, and without the presence of compensating gearing the machine would be prevented from turning freely, which in a device of this class is of the greatest importance, as will be readily understood.

For the purpose of preventing the free end of the conveyer-pan 101 from being lowered too far, or rather for the purpose of controlling and regulating the exact point to which it may be lowered, I provide a pair of rods 108, pivot'ally connected with the flanges at the edges of said pan and extending upwardly through a frame-bar or, if preferred, through lugs or brackets connected with said frame-bar and provided at their upper ends with regulating-nuts 109. It is obvious that the chains 100 should be of sufficient length to permit the free edge of the conveyer-pan to be lowered as far as shall be necessary under any circumstances; but by means of the connecting-rods 108 the free edge of said pan may be sustained a short distance above the ground. This is for the purpose of preventing it from acting as a scraper, whereby the dirt and refuse will be carried in front of the brush. The resilient shield 104, which in part supports the conveyer pan 101, also performs an important function in so sliding over the refuse and carrying the free edge of the conveyer-pan over the same as to insure its being operated upon directly by the brush member, whereby it is caused to pass over the conveyer-pan and into the receiver 32.

From the foregoing description, taken in connection with the drawings hereto anneXed, the nature of the invention and the operation and advantages of the same will be readily understood by those skilled in the art to which it appertains. The rotary brush member of which I avail myself for the purpose of gathering the refuse is not per se a part of my invention, rotary brush members having for a long time been well known for the purpose of gathering and collecting refuse. The invention resides more particularly in the means for receiving the refuse, as it is being gathered or collected, in the mechanism for elevating the receiver and for dumping or discharging its contents into a larger receptacle carried and supported by the frame of the same organized machine of which the receiving and gathering devices form a part, and, further, in so mounting the several devices upon a wheel supported frame provided with pedally-operated propulsion means that the entire machine may be propelled over the ground and operated successfully to gather the refuse by an operator seated upon the machine, the principal I and general object of the invention being to furnish a simple and conveniently-operable organized machine whereby the gathering of refuse shall be greatly facilitated and whereby it may be effected in a simple, convenient, and inexpensive manner.

In the operation of the machine the operator occupying the seat 17 may ride easily and swiftly from a central point or depot to the point where operations are to take place. While the machine is thus being transported the operative parts are held elevated in the position illustrated in Fig. 2 and being of a comparatively light nature will not to any serious extent hamper the progress of the operator. As soon as the place of operation is reached the operator, by means of the lever 96, will throw the rotary gathering member 40 into contact with the ground, simultaneously lowering the conveyer-pan 101'to its proper position and throwing the operating mechanism for the rotary brush member into gear, as has been already described. It is here to be observed that the throwing into gear of the rotary brush is effected in an eX- tremely simple manner, the driving mechanism being of the simplest possible nature in order to avoid any of the parts being choked by dirt. I have consequently avoided the use of complicated clutch devices, which would be easily choked and rendered temporarily useless. Another important feature is the use of the vertically-resilient connecting-rods 89 with the loops 89 whereby the parts directly operated thereby will beretained in their desired relative positions with the utmost security, while the rigidity where by they would be exposed to breakage even by slight jarring or jolting of the machine is entirely absent. As the machine progresses the refuse will be caused to pass over the con- Veyer-pan 101 into the box or receiver 32 over the lip 34 at the front edge of said box, upon which the rear edge of the pan 101 normally rests. When a quantity of refuse has accumulated in the receiver 32, the machine is stopped. The operator then, by means of the lever 55, elevates the dust-receiver 32, which as soon as it comes under the influence of the upward pull upon the arms of the yoke 48 will slide forwardly upon the offset portions 28 of the supporting-bars 26, thereby enabling the lip 34 to pass out of engagement with the rear end of the conveyer-pan 101. The dust-receiver will then swiftly be elevated in the manner which has been already described until the pins 69, coming into engagement with the hooks 67, will cause the receiver to be tilted until the lid 36 swings open and the contents of the box is dumped upon the hoppers or chutes 75, whereby it is discharged into the can or into such means as have been provided for the reception thereof. By operating the lever 55 in a reverse direction the dust-receiver will be lowered and when it approaches the lower limit of its movement will be pushed by the shoulders or offsets 28 in a rearward direction,

thereby causing the lip 34 to pass under the rear edge of the conveyer-pan 101. In this lowered position the receiver 32 will be securely maintained by the action of the hooks 59 upon the levers 58, operated by means of the connecting-rods 57 and hand-grips 56, said hook members engaging under the crossbar 24, as hereinbefore described. This dumping mechanism may be operated, if desired, without necessity of throwing the gathering mechanism and the means for transmitting motion out of gear. When the can or receptacle 7 O or the means for receiving the refuse is full, it may be dumped easily and quickly detached and an empty one substituted in place thereof.
