To all whom it may concern:
Be it known that we, FRANK HEDLEY and JAMES S. DOYLE, both citizens of the United States, and residents, respectively, of Yonhers and Mount Vernon, in the county of Westchester and State of New York, have made a certain new and useful Invention in Street-Sweeping Machines, of which the following is a specification.
This invention relates to street sweeping machines. The object of the invention is to provide an apparatus of the nature referred to which is simple in construction, economical to 5 manufacture, easy to operate, and eflicient in operation.
'A further object is to provide a street sweeping apparatus wherein is employed a rotary sweeper carried by a frame in such 2o manner that said sweeper may be swung laterally and horizontally from one side to the other of the frame on which it is mounted.
Other objects of the invention will appear more fully hereinafter.
The invention consists substantially in the construction, combination, location and relative arrangements of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally so pointed out in the appended claims.
In the drawings: Figure 1 is a view in 'top plan of a sweeping apparatus embodying the principles of our invention, positions of the rotary sweeper on opposite sides of the carrier frame being indicated in dotted lines. ,Fig. 2 isa view in side elevation of the same. Fig. 3 is a view in horizontal section on the line 3, 3, Fig. 2, looking in the direction of the arrows, parts broken ofii.
40 It is a common practice to employ rotary sweepers mounted upon frames which arepropelled along the streets to be swept, or'
along track rails of street car systems, the sweeper being suspended underneath the as carrier frame and ordinarily disposed 1n a generally transverse position across thev frame and in a transverse direction to the line of travel or propulsion of the frame. In the operation of such sweepers, so arranged, a comparatively limited area is cov ered, and where such a machine is employed to clean snowor dirt along the. tracks of a street car system, or instance, the result is to le vethe. snowor dirt swept from-t e .65; patent he iyeepeapi edapin 1ine;;para1.--.
lel and closely adjacent to the trackrails, making it diflicult and inconvenient for pas sengers to board or alight from cars operating along the track system. Moreover if the sweeper is arranged to extend beyond the sides of the carrier frame in which it is mounted, on one side or the other thereof, the vehicle which carries the sweeper must b turned around at the end of the line in order to enable the sweeper to operate at'the opposite side of the track on the return trip,
and in many instances it is inconvenient or undesirable to turn the vehicle.
It is among the special purposes of our present. invention to provide a carrier de signed to operate on the track rails of a street car system and to mount thereon a rotary sweeper in such manner as to permit the sweeper to be rocked'or swung into position to project or extend beyond either side of the carrier without disturbing or interfering with the drive gearing through which the rotary brush is operated, thereby enabling the apparatus to clearaway snow, rubbish or the like from the immediate vicinity of thetrack rails, the brush open ating on one side of its carrier vehicle while said vehicle is moving in one direction and on the other side while moving in the opposite direction.
While the principles of our invention may be carried out in many specifically different embodiments, without departure from the spirit and scope of the invention as defined in the claims, we will describe one arrangement as illustrative of the principles involved and which we have found to be simple and efficient.
In the construction shown A. designates a vehicle which, in the instance shown is mounted on supporting wheels 13. If desired, though not'neoessarily, the supporting wheels B maybe truck wheels and may op erate along the track rails C of a street rail way system, the trucks being located at the ends of the vehicle.
Intermediate its ends the body portion D of the vehicle" A is elevated or arched, as clearly shown in Fig. 2, leaving the end portions E, with an open space F, between them. Extending a short distance into the space F, from the base of one of the end compartmentsor portions E is a support G, in which and in the overhanging bodvpart Dis journaled' a rt al h ft M nted upon shaft H to rock therewith is a frame .J, portions of which extend on opposite sides of the shaft H. In one portion of 'frame J is journaled a horizontal shaft K tated. The frame J. and the motor and sweeper devices and intermediate gearing are located and operate in the space F between the ends E of the vehicle carrier A. In order to enable the sweeper L to operate at one side or the other of the vehicle, as indicated in dotted lines in Fig. 1 it is only necessary to rock the frame J laterally and horizontally about the vertical axis of shaft H, in one direction or the other, as may be desired. This may be accomplished in many different ways, as, for instance,'by attaching frame J to shaft H so as to rock therewith, and providingsome means for rocking said shaft H. A simple arrangementis shown wherein shaft H is rocked axially by means of a small auxiliary motor P, through suitable gearing R, S.
In operation the sweeper L is liable to encounter rough or uneven surfaces, stones, cobbles or the like. In order to avoid damage or injury it is desirable to provide means whereby in such event, the sweeper may easily ride over or clear the obstruction. vTo this end we propose to mount the shaft H for vertical longitudinal movement through a desirable range.v To permit such vertical movement of shaft H one or the other of the intermeshing gears S. B. may be provided with elongated teeth. By this arrangement it will be readily seen that when the sweeper L encounters an obstruction in its path the entire frame J can rise sufiiciently to permit the sweeper to pass or ride over theobstruction, without interfering with the sweeper drive gearing or the gear ing which rocks the frame J laterally. At the same time the weight of the frame "J and of the parts carriedthereby is imposed on the sweeper L to efficiently hold the same to its work. The motor M serves as a counter.
weight for the portion J of the frame which carries'the brush L.
It will be readily seen that the provision of the open space F intermediate the wheei or truck supported ends of the vehicle affords a most convenient arrangement to permit the sweeper to be swung laterally and horizontally so as to project or extend beyond either side of the vehicle, and at any desired angle. Ordinarily, and in order to deflect the sweepings away from the vehicle, or, for instance, from the trackrails, the sweeper will be somewhat inclined outwardly and rearwardly with reference to the direction of travel, and consequently it lsnnnecessary to turn the vehicle around when the Vehicle reaches the end of a line. All that is necessary to do to permit the sweeper to operate on the opposite side of the vehicle when the latter proceeds in the opposite direction on its return trip without turning around at the end of the trip is to swing the frame J to the other side of the vehicle and in similar outward and rearwardly inclinedrotation with respect to the new line of travel of thevehicle. And this action does not even require a reversal of the motor M. While the car is being run along streets or tracks which do not require the operation of the sweeper and also while passing other vehicles occupying the street when the sweeper is in operation, the brush and its supporting frame will be swung into position underneath the car and therefore will not interfere with other street traffic.
Having now set forth the objects and nature of our invention and a construction embodying the principles thereof, what .we claim as new and useful and of our own invention, and desire to secure by Letters Patent is,
1. In a street sweeping machine, a vehicle,
a laterally. movable supporting frame adapted to lie longitudinally under said vehicle and comprising oppositely extending portions, a sweeper carried by one of said extending portionsof said frame and a motor carried on the other extending portion of said frame for driving said sweeper.
