To aZZ whom it may concern:
Be it known that I, WILLIAM Y. GAMBEE, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Street-Sweeping Machines, of which the following is a specification.
The invention relates to improvements in re street-sweeping machines; and it consists in the novel features of construction and com binations of parts hereinafter described, and particularly pointed out in the claims.
Referring to the accompanying drawings,
r 5 Figure l is a front elevation of a street-sweep ing machine constructed in accordance with and embodying the invention. view of same, the brushes-being omitted from the sprocket-Wheels for clearness of illustra-;
tion and a portion ofthe wagon being broken away. Fig. 3 is a side elevation of same, one of the main supporting-wheels being omitted for clearness of illustration. Fig. 4 is an end view of the machine, the brushes and their chains being omitted from the sprocket-wheels thereof; and Fig. 5 is a detached elevation of a portion of the brushes and chains to which they are secured, and which brushes and chains are omitted from Fig. 4.
0 In the drawings, A designates the wagon portion of the machine, said wagon being: mounted upon supporting-wheels B and pro-' vided with the drivers seat 0. The wagon A is provided with the receptacle D, which is open at its upper end and is adapted to receive the sweepings from the brushes hereinafter described.
The receptacle D issimply an elongated box, preferably mounted upon rollers, as
c shown in Figs. 1 and 3, and provided on its end with a handle to facilitate its withdrawal by hand from the wagon-frame.
In rear of the receptacle D, and at a slightly higher elevation than the upper edge of same,
Fig. 2 is a top the rear end of the said wagon, and thence extend downward, as indicated more clearly in Fig, 3, to a point directly over the rear axle H, whence the said bars'F curve rearward and then on an inclined plane upward to the shaft E, while the bars G are in the'form of braces and extend from said axle E downward and forward to the bars F just in rear ofthe receptacle D, whereby the bars F G are caused to constitute a rigid frame capable of bearing the series of brushes and their sprocketwvheels, as hereinafter explained. The said frames, composed of the bars F Q, are strengthened and aided in the supporting of the sweeping mechanism by means of the bars I, which extend from the wagon Aalong the lower sides of the frame supporting the receptacle D and thence upward to the lower portion of the bars F. where suitable boxes J. arefor'med for the journaling of the ends of the main axle H. The bars F I converge toward each other in rear of the receptacle D and form supports of great strength and ri- I gidity. 7 5
Upon the shaft E are provided the series of arms K, and from these arms there extends downward the series of tubular rods L, whose lower ends engage and'support the short axles M, which are in line with each other, and each is provided with the pair of sprocket-Wheels N N, the latter being of usual construction and corresponding in size and being in alignment with the pairs of sprocket-wheels O O, secured upon the shaft E, which is continuous and not in sections or composed of a series of short shafts.
The tubular rods L are held'at their upper ends by means of the screws P, Fig. 3, by which the said rods may be adjusted verti- 9o cally to a limited extent for the purpose of adapting the sprocket-wheels N O to the condition of the chains Q, upon which the brushes R are secured. The lower. ends of the screws P enter the upper ends of the tubular rods L, 5 1 wherein are provided internal threadsto engage said screws. The chains Q, carrying the brushes R, are continuous, as illustrated in Fig. 3, and each pair of the sprocket-wheels N O is provided with one endless chain of I00 brushes. In the present instance four pairs 0 the sprockets N O are provided, and hence the the machine will carry four endless chains of brushes R.
Upon the rear portion of the frame supporting the receptacle D is provided the pan S, which is provided with the sides T and is sufficient in width to extend entirely across the machine and inclose at its sides T all of the chains of brushes R. The upper portion of the pan S extends upward to a point ad jacent to the rear upper edge of the receptacle D, and at the lower portion or edge of the pan S is provided a rod V, upon which are the curved sheet-metal plates V, which, as illustrated in Fig. 4, correspond with each other in size, and are in transverse alignment with each other and constitute the lower portion of the pan S. The lower edges of the plates W are adapted to follow the surface outline of the street, and said plates being independent of each other will closely follow the irregularities of the surface to be swept. The pan S is adapted to be moved toward or from the brushes R, in order to adapt the same to the condition of said brushes or the nature of the material being swept up the pan, by means of the springs X, ratchet Y, and pawl Z, the springs at one end having a bearing against the pan S, as shown in Fig. 3, and at their other end being secured to the shaft or of the ratchet-wheels Y, the said shaft being secured in a suitable bearing to the side bars I, and being adapted when turned to wind the springs X for the purpose of increasing or decreasing their tension, and thus moving the pan S rearward toward the brushes R or permitting it to lower from said brushes. The pawl Z is secured upon the said bar I in position to engage the teeth of the ratchet Y and thereby lock said ratchet in the customary manner.
Upon the rear main axle H is secured the gear-wheel b, as shown more clearly in Fig. 4, which engages a pinion-wheel 01, secured upon (a short shaft 6, mounted in bearings furnished 1 by the bifurcated armsf gof the rod h, which is suspended from the shaft E and extends downward for the purpose of supporting the axle eand the wheels thereon, the lower end of the armf of said rod being retained upon the axle H. Upon the ends of the axle e are secured the sprocket-wheels 2', upon which run the sprocket-chains j j, as shown in Fig. 4, and which are in alignment with the smaller sprocket-wheels 7c, rigidly secured upon the shaft E.
The purpose of the gear-wheels b d, axle e, sprocket-wheels i k, and chains j is to communicate power from the main axle H to the shaft E, and through said shaft to the sprocketwheels 0, chains Q, and sprocket-wheels N, whereby the series of brushes R are caused to have a traveling movement and to sweep the refuse up the pan S and into the receptacle D.
Upon the axle H is provided an ordinary clutch-box m, connected, as shown in Figs. 2 and 3, by a draw-rod n, bell-crank 0, rod 19, lever q, rod r, arm 0", and shaft '1' with the hand-lever s, which is in convenient relation to the seat 0 and may be operated by the driver to withdraw the clutch m from the gear-wheel b or to cause the engagement of said clutch and gear-wheel as desired. The gear-wheel b is free upon the axle H, while the clutch-box m is keyed in the usual manner thereon, so that when the clutch-box is free of the gearwheel Z) the latter will remain idle and the brushes R will not travel, and when the said clutch-box m is in engagement with said gearwheel I) the latter will be thereby locked to the axle H and rotate with the same and impart its movement through the gear-wheel d, axle e, chains j, and sprocket-wheels i k. to the shaft E, and thence to the sprocket-wheels N O and brushes R.
Within the bars F is journaled the rockshaft t, upon each end of which, as shown in Fig. 3, is secured the arm to, which, by means of a link as, is connected with the arm y, hung from the end of the shaft E and connected at its lower end by the rod z to the arm A, which is firmly secured upon the end of the shaft B, having the pinion-wheel C, the latter being in engagement with the worm D on the vertical shaft E, having upon its upper end the hand-wheel F, by which said shaft may be turned at will by the driver from the seat 0. The purpose of the arms and rods lettered 'w, 00, 'y, z, and A, the shaft B, and the worm and pinion O and D is to enable the driver to move the rock-shaft t in its bearings and thereby to cause the springs G, secured upon said shaft, to move either outward and rearward or inward and forward, and draw through the chains H the axles M outward from the pan S or permit them to approach said pan.
When by means of the worm D and pinion O the rod 2 is drawn forward, the latter will, through the arms to y and rod 00, turn the rock-shaft t to move the springs G rearward, and thereby, through the chains I-l, pull the axles M, sprocket-wheels N, lower portions of the tubular rods L, and the series of brushes R rearward, while, upon a reverse or rearward movement being imparted to the rod 2 from the worm and pinion, the rock-shaft 15 will be turned in a reverse direction and the springs G will permit the shafts M and their connections to move downward and forward of their own specific gravity. By means of the worm D and pinion O, and the connections just described intermediate the said pinion and the axles M, the brushes B. may be lifted clear of the ground when desired.
Upon the opposite side bars F are pivotally mounted the standards 1, carrying upon their upper ends the sleeves J, adjustably held in place by screws K, and which sleeves have pivotally secured between them the bar L, upon whose lower surface is rigidly affixed the metal fenderM, which is curved along its front portions and is directly over the receptacle D, and the purpose of which is to prevent the dirt swept upward by the brushes R which enter the sleeves J and permit of the fender being turned axially to any desired position, and the said fender may be adjusted 5 as to its position with respect to the receptacle by means of the segments N, formed on said standards I and having elongated slots engaged-by a set-screw 0 from the bars G. The segments N, with their elongated slots and the set-screws O, are of ordinary con struction and are intended as a means of ad justing the said standards I and fender M, the said standards being free to turn on the pivots securing them at their lower ends to the side bars F.
Upon the bar L, carrying the fender M, is secured the series of rearwardly-projecting pins P, forming a comb against which the .points of the bristles of the brushes R pass. during their traveling movement, and which I will have the eifeot of cleaning the said bristles of all foreign matter prior to their descending to the ground for further usein carrying the sweepings up the pan S to the receptacle D.
The rear wheels B, during any backward movement of the machine, will revolve freely upon the ends of the axle H without turning the latter, and hence without setting in motion the series of brushes R; but during all forward movement of the machine the wheels B and axle H will be locked together by the customary pawl-and-ratchet mechanism used in street-sweeping machines and located in casings Q at the inner side of the hubs of said wheels, as illustrated in Fig. 4. The pawl-and-ratchet mechanism for the ends of the axle H is not specificallyshown, since said elements are well known in the art and are not claimed herein.
From the foregoing description it will be seen than the motion of the rear wheels B, while the machine is going forward, is communicated through the axle H and clutch-box 'm to the geanwheels b d, shaft e, chains j, sprocket-w heels 2' k, shaft E, all of the sprocketwheels 0, and the series of brushes R, and that the revolution of the shaft E and the sprocket-wheels O is communicated, through the chains Q, carrying the brushes R, to the sprocket-wheels N, mounted upon the short shafts M, and hence that during the forward travel of the machine all of the brushes R are in constant traveling motion sweeping the street and moving the refuse up the pan S and into the receptacle D. When it is desired to stop the motion of the brushes R while the machine is going forward, the driver, by moving the lover 8, may withdraw the clutch m from the gear-wheel b and cut off the power of the wheels B and axle H from the gear-wheels b d, chains j, and brushes B. When it is desired to lift the brushes R, sprocket-wheels N, and axles M from theiroperating position, the driver will simply rotate the shaft E in one direction, and thereafter when it is desired that said brushes and shafts may lower again the driver will simply reverse the movement of the shaft E. The brushes R, sprocket-wheels N, and shafts M are suspended by the tubular rods L from the shaft E, which is the pivotal point of the sweeping mechanism, and the distance between the sprocket-wheels N and the sprocketwheels 0 on the said shaft E is adjustable by means of the screws P, which engage threaded apertures in the arms K and enter the upper threaded ends of the rods L. The fender M may be adjusted vertically upon the stand ards I by means ofthe sleeves J and screws K, or adjusted axially by means of the pivots which secure said fender to said sleeves J. The standards I may be also adjusted toward or from the brushes R, and hence the pins P supported by said standards may be moved toward or from the brushes they are to comb. The pan S is secured by a hinge to the upper rear portion of the frame about the receptacle D, andits lower portion may be adjusted toward or from the brushes R by means of the springs X, ratchet Y, and pawl Z. The parts of the machine are thus rendered adjustable at the will of the operator in a convenient manner and are adapted to eifectually perform the work intended for them.
The machine constructed as above described is thoroughly durable and entirely practicable, and in use ithas been demonstrated that the lower sections or fingers W of the pan will follow the irregularities in the surface over which the machine is passing and that the endless chains of brushes swung from the shaft E and independently yielding at their lower ends with the short shafts M will effectually clean the irregular surfaces of streets.
