JOHN A. DOHERTY, on NEW YORK, N. Y.
STREET-SWEEPER.
SPECIFICATION forming part of Letters Patent No. 537,278, dated April 9, 1895.
Appli ion filed September 24, 1 8 91. 1 Ben ewed January 22, 1 8 9 5. Serial No. 5 3 5,8 2 Z. (No model.)
To all whom it may concern:
Be it known that I, JOHN A. DOHERTY, a
citizen of the United States, residing in the city, county, and State of New York, have invented new and useful Improvements in Street-Sweeping Machines, of which the following is a specification. This invention relates to improvements in street sweeping machines consisting of an adjustable bucket to receive and hold the sweepings delivered thereto by the usual revolving broom, and a suspended box into which the sweepings are tobe deposited from time to time from this adjustable bucket, and when a sufficient quantity of sweepings shall have been deposited in said box, the whole may be deposited in separate masses therefrom to be subsequently removed in any convenient manner.
Figure 1 represents a side elevation of'this machine completec Fig. 2 is a plan or top view of Fig. 1. Fig. 8 is a central, longitudinal section of Fig. 1, showing the different positions of the bucket to receive and discharge the sweepings delivered thereto by the revolving broom. Fig. 4 is a similar View to Fig. 3, showing the suspended box into which the sweepings are to be deposited from the bucket in position to discharge its contents in a mass in one place; Fig. 5, a transverse, sectional view through the line m, w, of Fig. 1, to show more clearly the manner of suspending the bucket, the other parts of the I machine, not necessary thereto being omitted.
Similarletters of reference indicate corresponding parts throughout the several figures.
The accompanying drawings represent my invention as applied to an ordinary two wheel sweeper, though it is evident that it would be equally well adapted to a three or four wheel sweeper.
A, in the accompanying drawings is the frame of an ordinary sweeping machine with two wheels and designed to be drawn by one animal, upon the axle B, of which is suspended an oscillating, adjustable box 0, to receive and contain the sweepings from an adjustable bucket D, from time to time until a sufficient quantity shall have been collected and deposited therein,,and subsequently to discharge the mass therefrom in one place by turning. the box on its axis to the position shown in Fig. 4. At the rear end of this sweeper is arranged the usual revolving broom E, adjustable and driven by an endless chain F, from a pulley G, secured to the axle B, and a corresponding pulley H, mounted upon the outer end of the shaft of the broom as shown in elevation Fig. 1 and plan Fig. 2. Directly in front of this revolving broom E, and at the proper distance therefrom is suspendedan adjustable bucket D, extending crosswise and, somewhat longer than the broom E, in order to receive all the sweep ings delivered thereto by the broom. This bucket D, is suspended by chains (1. passing over a roller I, mounted upon the frame A, in suitable bearings, over which roller these chains are to be drawn by a chain 1), extending to and connected with a Windlass J, to raise and tilt the bucket to deliver its contents into the box 0, of the sweeper as shown in dotted lines Fig. 3, and to be again lowered in position to receive the sweepings from the broom in same figure. To limit the up and down movements of this bucket D, slotted guides K, are provided and secured to the frame A, into the slots of which guides the ends of the rod d, extend and to which rod the bucket D is secured. When this bucket D, is lowered and in -position to receive the sweepings from the broom, the ends of the rod d, rest in the'lower ends of the slotsf, and when the bucket is drawn to its extreme upward movement the rod cl, will be arrested at the upper ends of the slots and the bucket tilted so as to deliver its contents into the box a, over its rear edge as shown in dotted lines Fig. 3.
As a convenient and practicable means of raising and loweringthe bucket D, when required, a Windlass J, with hand-wheel d, is provided and placed near the drivers seat, which Windlass is connected with the bucket by means of the chains b, a, so. that by turning this hand-wheel d, backward and forward the bucket D, may be raised and tilted to discharge the contents therefrom, and lowered to position to receive the sweepings as shown in Fig. 3. It will be observed that when the bucket D, shall have been elevated by means of the hand-wheel d, and chains 19, a, to the required height, the guides K, will arrest its further upward movement, and then by continuing to turn the hand-wheel d, the bucket will be tilted backward with its rear edge extending over the edge of the box 0, to deposit its contents therein as before stated, and represented in dotted lines Fig.
The chains (1, by which the bucket is suspended and by which it is to be raised and lowered are attached thereto in front of the guide-rod (Z, a sufiicient distance to tilt the bucket at its extreme upward movement, and to maintain the bucket in a horizontal position while being raised and lowered, the preponderance of weight being in front of the suspension chains.
In order to maintain the front edge of the bucket D, in proper position steadily, and independent of the suspension chains a, while receiving the sweepings from the broom, stops it, are secured to its lower side which bear against the guides K, as shown in Figs. 1, 3 and 4. By this arrangement of stops, the bucket may be lowered and its front edge maintained in a fixed position to receive the sweepings therein independent of any exact movement of the hand-wheel d, of the Windlass which would be difficult in the absence of these stops. It will also be observed that this bucket is practically pivoted so as to pass over obstructions and to return by its own gravity in position to receive the sweepings, the guide-rod d, being the pivot, and the stops 71, together with this guide-rod to maintain it horizontally as shown.
As a convenient means for raising and lowering the revolving broom E, a lever L, mounted upon uprights M, secured to the frame A, is provided, to the rear end of which are attached the chains S, and by which this broom is also suspended in the usual manner, the opposite end of this lever extending for ward toward the front of the sweeper to be operated by the attendant as shown in Figs. 1, 2, 3, and et.
In constructing and arranging the box C,
' it should be suspended upon the axle B, so
that the front side thereof shall be heavier than that in rear of the axle in order to maintain itself in position when empty, and not to turn backward upon the axle of its own weight. To maintain this oscillating box 0,
in position whether loaded or unloaded, a stop-bar Z, is provided which is supported in bearings m, secured to the frame A, of the sweeper and against which bar a stop V, se-
cured to the box 0, bears as represented in the several figures. When the load ofsweepings in the boxis to be deposited in one place, the stopbar Z, is withdrawn and the box permitted to turn on its axis to the position shown in Fig. 4, and when empty may again be returned in place and locked to receive the sweepings as before stated. As soon as the sweepings are received from the broom, by the bucket, raised and discharged therefrom into the box in sufficient quantity they are in turn discharged from the box in masses at different places the same as they would be gathered by handbrooms from windrows left by sweepers not provided with my improvements; and so on the operation maybe repeated-the bucket to continue to receive, elevate and discharge its contents into the box and subsequently deposited therefrom at intervals,in different places as before stated.
Having thus fully described my invention, what I claim therein as new, and desire to secure by Letters Patent, is
1. In a street sweeping machine the combination with an oscillating box to receive and deposit the sweepings therefrom at intervals, of a bucket suspended and capable of being raised and tilted to discharge the sweepings therefrom into said oscillating box, the guides by which the up and down movements of said bucket are governed and limited, the suspension chains by which said bucket is to be raised, and lowered to receive the sweepings being in front of said guides, whereby said bucket is maintained in a horizontal position while being raised and lowered substantially as herein set forth and shown.
2. In a street sweeping machine provided with a bucket suspended and capable of being raised and tilted to discharge the sweepings therefrom, and lowered to a fixed position to receive the sweepings, the guides by which the up and down movements of said bucket are governed and limited, and stops secured to said bucket in front of said guides whereby the bucket is maintained in position while receiving the sweepings independent of the suspension chains substantially as and for the purpose set forth.
