STREET-CLEANING APPARATUS.

Specification of Letters Patent.

Patented Mar. 20, 1917.

To all whom it may concern:

Be itknown that 1, WILLIAM P. TARRANT, a citizen of the United States of America, and a resident of Saratoga Springs, Saratoga county, and State of New York, United States of America, have invented certain new and useful Improvements in Street- Cleaning Apparatus, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to street cleaning apparatus and has special reference to hand carts which are adapted to carry a. bag or other refuse receptacle and are provided with a dust pan attachment.

One object of my invention is to provide a light and durable device of the aforesaid character that shall embody simple and ef fective means for guiding and operating the dust pan to either a position to receive refuse from the street or to discharge into the bag or receptacle carried by the cart.

Other objects and advantages of my invention will be set forth hereinafter, and in order that my invention may be thoroughly understood, I will now proceed to describe the same in the following specification and then point out the novel features thereof in appended claims.

Referring to the drawings:

Figure 1 is a side elevation of a street cleaning apparatus arranged and constructed in accordance with my invention.

A front elevation of the same apparatus is shown in Fig.2. v

Fig. 3 is a sectional plan view showing the dust pan attachment and taken on the line 3-3 of Fig. 1.

Fig. 4 is a sectional detail of one of the supports for the actuating frame, taken on the line H of Fig. 1 and drawn to a larger scale.

Fig. 5 is a sectional detail of the supporting ring which is adapted to support a bag or similar receptacle. This figure'is also drawn to a larger scale.

Like characters of reference designate corresponding .parts in all the figures.

The cart here shown comprises a frame 10, a pair of relatively large wheels 25, a relatively small guide wheel 26, a dust pan or receiver 30, and an actuating frame 10 therefor. i I

The frame 10 comprises a pair of spaced angle bars 11, transverse bars 18 secured thereto, a pair of central uprights 12 having extensions 13 extending at an angle and supporting at their outer ends a transverse handle bar 14; a strap 15 connecting the handle bar 14c with one of the bars 18, and a pair of guide bars 16, constituting a guide frame and attached at the bottom to the forward ends of the angle bars 11, and curved at their upper ends and attached to intermediate points in the extensions 13.

Secured to the uprights 12 are a pair of stub axles 17 on which the wheels 25 are rotatively mounted, the arrangement of parts being such that the frame is supported at a short distance above the ground when the wheels are mounted on the stub axles.

The dust pan 30 has a reinforced edge 31 which is adapted to make contact with the street or ground, and a funnel-shaped body having a rectangular discharge opening The opening 32 is at the upper end of the dust pan when it is in position to receive refuse from the street as shown in Figs. 1 and 2; and near its upper end is secured a transverse reinforcing bar 33, the ends of which extend beyond the sides of the pan and are bent into transverse loops 34 surrounding the guide bars 16 between which the pan is mounted as clearly shown-in Fig. 3, to form a lost motion connection therewith.

A second reinforcing rod 19 is secured to the dust pan 30 near its lower edge and terminates in pivoted loopsor sleeves 21 which are arranged to slide on the guide bars 16, and cooperate with the loops 34 of the bar 33 in guiding the movement of the pan.

Pivotally mounted on the stub axles 17 within the wheels are a pair of blocks 4-1 each having a curved edge surface 12 provided with a groove 43.

The actuating frame 40 comprises a pair of curved bars 4A which are respectively seated in the grooves 13 of the blocks 41 and are held in position by straps They are tied together at their outer end by a handle bar 46 and at their inner ends they are pivotally connected to pin projections 17 of the dust pan 30. The arrangement is such that the bars 4% slide through the loops 45 of the blocks 11, the grooves 43 constituting guides for maintaining the parts in suitable relations.

Secured to one of the strips 18 is a forked frame 27 on which the wheel 26 is pivotally supported near the central plane of the cart, and above this is a pedal projection 28.

Between the extensions 13 of the uprights 12 is remo-vably supported a ring-shaped carrier 48, socket projections 49 which extend from opposite points of the ring, being mounted on studs 49* on the extensions 13. As clearly shown in Figs. 1 and 5 the ring 45 is preferably provided with a plurality of pins 50 which are adapted to hold the cloth bag or similar receptacle after it has been stretched on the ring 48. The ring is reversible so that the spikes may extend either upwardly or downwardly.

The operation of the device is .as follows: The hand cart is moved from place to place by the operator who grasps the handle bar 14 and holds the dust pan in an elevated position, by means of the handle bar 46. lVhen he desires to utilize the dust pan attachment he lowers the pan into the position shown in Figs. 1 and 2, by permitting the handle bar 46 and the guide frame to swing about the stub axles 17 as pivots. The refuse is then scraped or swept onto the dust pan and the operator then pulls backwardly on the handle bar 46. This action causes the bars 14 of the actuating frame to slide in the grooves 13 at the same time that the blocks 41 swing on the, axles 17 on which they are mounted. The pan itself is first tilted upwardly at its outer edge about the center of the rod 19 as an axis, until the lost motion provided by the loops 3 1 is taken up. It is then elevated to the position shown in broken lines in Fig. 1, being guided in its entire movement by the guide bars 16. In this position the opening 32 of the funnelshaped portion of the pan is in position to discharge directly into the bag or receptacle which is supported on the ring 18. This arrangement has the advantage of working very readily and of tilting the pan so as to prevent dropping any of the refuse while the pan is being elevated.

As soon as a bag is filled it is removed and replaced by another, the stretching and sup porting ring 4-8 being removed with the full bag and an empty bag stretched onto it before it is replaced, thereby facilitating the change.

Instead of using a bag, a barrel or can may be set on the frame between the wheels, in position to receive refuse discharged from the dust pan.

The guides 16 are removable, and so is the dust pan and its frame, so that the cart may be used for general purposes without these attachments.

What I claim is:

1. A hand cart comprising a frame constituting a receptacle support and having a guide frame and axle projections, Wheels mounted thereon, adust pan slidably supported on the guide frame, and a pair of curved arms pivotally and slidably supported on the wheel axles for raising the pan on the guide frame into position to discharge into the receptacle.
