To wZZ whom it may concern: 4

Be it known that we, WILLIAM HENRY MEL- VIN, residing at Westminster, in the county of Middlesex, and ANDREW MANN, residing at Oroydon, in the county of Surrey, England, subjects of the King of GreatBritain and Ireland, have invented certain new and useful Improvements in Apparatus for Collecting Mud, Dust, or other Street Refuse; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters and figures-of reference marked thereon, which form a part of this description.

This invention relates to apparatus for 001- lecting mud, dust, and other street refuse and for transferring such refuse to a van or cart.

Figure l of the drawings represents in elevation the right-hand side of the apparatus.

Fig. 2 is a plan View, partly in section,of the lower part of the apparatus. Fig. 3 is an elevation of the left-hand side of the apparatus. Fig. 4 is a front elevation. Fig. 5 is a vertical longitudinal section of the collecting trough and apron, and Fig. 6 is a plan view of the under side'of these parts.

A suitable box-like frame ais provided with inspect-ion lids or covers I) c, mounted on two large road-wheels d and,if desired, also'on a small wheel e in a swiveling fore-carriage f, which may be connected to a dust van or cart, (not shown,) the whole being propelled by horse or motor power. The apparatus is provided, as best seen in Figs. 1, 5, and 6, with an inclined apron constructed of two parallel sections g and h. The section 9 is rigidly mounted 'in the frame a, while the section It is mounted on,*and slidably connected to, the rigid section by means of guidepins 52, which aresecured at one end to lugs 54:, mounted on the-under side of section h, and headed pins 56. The other ends of the pins pass through and. have bearing in lugs 53, mounted on the under side of section g, and a coiledspring 41 is mounted on each pin between the two lugs and by hearing against both lugs tend to keep them apart and the apron extended. Guide-slots 55 are formed frame a.

in the movable section It, and headed pins '56 on the stationary section pass through the slots and limit the sliding movement of said movable section. By thus making the apron in two sections and connecting them as do scribed a resiliency is given to the frontsection which permits it to give when an obstacle is encountered, thus lessening the 'liability of breaking the machine. The front section is also provided with rounded corners, as shown in Fig. 6, to decrease the liability of its catching on tram-lines or other obstacles. Normally when working the sliding apron h is just touching the ground and receives the mud or refuse which is thrown thereon by a cylindrical brush it. This brush is rapidly rotated indirectly 'by one of the road-wheels by means of a sprocket-wheel l, loosely mounted on the axle d and caused to turn, with the wheel, by pinconnections 59. A chain m, traveling over said sprocket-wheel Z, imparts motion to a sprocket 71, mounted on a stud 0 on a frame p, that is secured to the A second sprocket g, which turns with the sprocket n, imparts motion, through the medium of a chain 1", to a sprocket s on a stud t, fixed to the lower part of said frame a,

and with the sprocket 8 another sprocket u,

mounted on the same stud, is caused to turn and communicates motion through the medium of a chain '0 to a sprocket'w on the shaft of the brush it.

The apron or the movable part hthereof is connected by links m to a hand lever or levers y, pivoted to the framea, for the purpose of withdrawing the section It back onto the stationary section 9 away from the ground when the apparatus is traveling but not collecting refuse. In order that the dirt or refuse thrown up by the brush konto the apron may travel up the same and into a horizontal trough 2, (best shown in Figs. 2 and 5,) we provide a number of squeegees l, which pass along in contact with the face. of the apron. These squeegees are mounted on endless chains 2, which pass around sprockets 3, 4:, and 5, said sprockets being mounted on spindles, having bearings in each side of the frame a. The spindle 6, on which the sprocket 3 is mounted, has on the left-hand side of the machine outside of the frame a,

Fig. 3, a sprocket 7, and this sprocket receives motion by means of a chain 8 and a sprocket 9, also mounted on the axle of the road-wheels and adapted to receive motion from the left-hand wheel by the pin connections 59, or said sprocket 9 may be made integral with the wheel.

The bearings 10 of the brush are adjustable as to height to allow for wear of the brush or otherwise. A suitable way of eifecting this adjustment at both ends at once is to suspend the bearings on screws 11, having miter-wheels 12 fixed thereto and which gear with miter-wheels 13, mounted at each end of a horizontal shaft 14, said shaft having a hand-wheel 15 or the like to actuate it.

The shaft 6 has also mounted thereon a gear-wheel 16, Fig. 2, which gears with a wheel 17, fixed on a shaft 18 of a horizontal screw conveyer 19, which has bearings at each end and worksin halfof the horizontal trough z and conveys all the refuse contained'in said half to the middle of the trough. The other half of the trough contains a similar screw conveyer 20, which conveys all the refuse contained in this half to the middle of the same, and motion to this last conveyor is obtained by a chain 21 from a third sprocket 22, mounted on the stud 0 on the frame 10, before referred to, (see Figs. 1 and 4,) to a sprocket-wheel 23 on the shaft of the conveyer 20. Bearing-blocks 57 are provided in the trough for the inner ends of the horizontal conveyer-shafts.

The object in bringing the refuse to the middle of the horizontal trough is to prevent the said refuse from clogging at the delivery end, as it is liable to do if only one horizontal conveyer be employed.

In order to raise the refuse from the middle of the trough so as to be able to deliver it over the tail-board of a van or the like, we provide a vertical conveyer-tube 24:, in which is mounted a screw conveyer 24., on the end of which latter is a bevel-gear 27, in mesh with a bevel-gear 26 on a horizontal counter-shaft 25, mounted at the top of and across the frame 29. This shaft 25 is rotated by means of a sprocket-wheel 33, mounted on one end thereof, said sprocket receiving motion through the medium of a chain 28,driven bya sprocketwheel 29 on the axle of the road-wheels.

At the junction of the vertical and horizontal conveyors we provide a manhole 30, Figs. 1- and 3, for the purpose of inspection, adjustment, and so on, and there is fixed a hinged spout 32, near the top of the vertical conveyer, for directing the refuse over the tail-board into the van or cart.

A suitable clutch 34, having an operating lever 35, Fig. 4:, is provided to disconnect the counter-shaft when the apparatus is traveling, but not otherwise operatin Nuts 41 and 45 may be employed to secure the spindles of sprockets 4 and 5 in their adjnsted positions in the bearing-slots in the casing. To adjust the sprocket 5 nearer to the broom, loosen the nuts, lower the spindle 4, and tighten the nut when in the desired position, then adjust the sprocket 5 nearer to the broom and tighten its nut. Wherever necessary, we provide jockey pulleys or rollers on adjustable studs to take up the slack of a chain, such as the jockey-pulley 31, bearing on the chain 28.

What we claim is- 1. An apparatus for collecting street refuse, comprising a suitable framing, a brush, a collecting-trough, a receiving-apron comprising a fixed section,and a movable section slidably connected to said fixed section and arranged to receive refuse swept thereon, an endless conveyer to move the refuse from the apron into said trough and means for conveying. the refuse away from the trough, substantially as described.

2. In an apparatus for collecting street refuse, the combination with a suitable framing, a brush at one end, and a collecting-trough at the opposite end of said framing, a receivingapron comprising a fixed section, and a movable section slidably connected to said fixed section, means for normally holding the movable section in contact with the road, means for withdrawing said latter section from the road and a conveyer to move the refuse from the apron, of an upright conveyer adapted to receive the refuse from the trough, substantially as described.

3. In an apparatus for collecting street refuse, the combination with a suitable framing, a brush at one end and a collecting-trough at the opposite end of said framing, a receivingapron comprising a fixed section, and a movable section slidably connected to said fixed section,springs for normally holding the movable section in contact with the road, levers connected to said movable section for sliding it back onto the fixed section, and an endless conveyer adapted to move over the apron and remove the refuse therefrom, of an upright conveyer adapted to receive the refuse from the trough, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
