Specification of Letters Patent. Patented Apr. 26, .1910- AppHcation med'August 16,1907. Serial No. 388,816.
To atlwhom it may concern:
Be it known that I, AUGUST SUNDi-I, a
citizen of the United States, residing at Yonkers, in the county of Westchester and 'State-of New York, have invented a new and-useful Improvement in Sidewalk Ashingais -a .spec
Another object is to rovide a construcftion' in which the electric motor is carried by a frame movable into a position above the walk when the device is in use, and movable in t-o a position below the walk when not 'in use; 7 1
1 Other objects of the invention will appear 'hereinafzten' the :novel combinations of elef'mwts being set forth in the appended claims. i v
-Referring to the drawing, in which is shown a construction embodying my invention, Figure 1 is a sectional elevation. of the hoisting mechanism, the sidewalk and the compartment therebeneath in which the device is installed; Fig. 2 is a diagrammatic view, of the electr-F '1 motor and reversing switch; and Fig. 3 is a view substantially on theline 38 of Fig.- 1.
The hoisting device is installed in a compartment 1 located beneath a sidewalk 2. The portion of the walk 2'over the compartment 1 may be supported by the horizontal framework 3 whlch is supported by the foundation wall 4 of a building and the.
vertica-lsupport 5. These latter rest on the cement floor 6 of the compartment 1. The compartment 1 communicates through'a door or passageway ,7 formed in the wall 4 with a basement or cellarfrom which theashes are to be removed. T
The sidewalk is formed with an opening 8 in which is mounted for vertical movement a frame A. This frame comprises vertical T-irons forming side members 9', a cross bar H 10 uniting the parts '9, braces 11, angle irons and a "top 13. When the frame is lowonedthe top 13' forms a coverfor the'opening Bin the sidewalkrandalso forms a stop available, and upon other coil with in practice.
to limit' the downward movement of the frame. The frame is guided in its vertical movement by guides 14 secured to the framework 3 and embracing the lateral flanges of the T-irons 9. Theweight ofthe. frame A and parts carried thereby is partially or wholly counterbalanced by counterweights V connected to the frame A by cables 15.
These cables are secured to the lower ends of the frame members 9 and pass over direction sheaves 16 su ported by the framework 3. The frame A is securely held in a raised position by pins 17 which may be placed in sockets formed in the side walls of the compartment 1 in such position that the pins engage the'upper surfaces of the counterweights when the frame is raised. Chains 18 may be used to prevent the loss of thev pins 17 The receptacle R which may be an ash can or other receptacle, or which may be replaced b any other article it is desired to lift or ower through the walk, is lifted and lowered by means of a-chain and pulle 5 having an arrangement similar to the or inaryblo'ck and-tackle. The'hoisting chain 19 is connected at one end toa support near the top of the frame A, which sup ort may be connected to or form partof tie motor frame. From this end the chain extends downwardly and around a loose pulley 20 .gnd up to-a drive sprocket wheel or pulley 1 (Fig. 3') with which the chain is preferably in positive driving engagement. The free end of the chain is provided with a hook 22 for a purpose hereinafter stated. The pulley 20 carries a hook 23 connected to the receptacle R.
The motor M is mounted in a casing 24 which is suspended from the cross bar 10 at the top,of the frame A. The motor shaft extends throu h the casing and is provided with a driveplnion 25 outside of the casing. The 1 inion 25 meshes with a connecting car 26 w llichin turn meshes with a gear w eel 27 secured to a shaft 28, to which is also secured the drive wheel 21. The kind of electric motor 'used will depend upon whether asupply of direct or alternatin current s ditions met shown an ordinary series wound direct current motor. The motor circuits are controlled by a reversing switch S. The switch is 'inclosed in a casing or switch box 30 (Fig.
In this 'instance I have 2) and comprises a. switch lever 31 pivoted at 32 and carrying insulated contacts 33, 34. Fixed contacts 35 and 36 are engaged by the contacts and 34 when the lever 31 is moved to the right, and fixed contacts 37,
46, the other'end of which is connected di-- rectly' to thenegative main. With the switch lever 31 in=an intermediate position as shown, the motor'circuits are open. If,
' now, the switch lever is moved to the right,
the contacts and 34 will engage respectively the contacts 35 and 36. This will close a circuit through the motor as follows: from the positive main through wire 44,
contacts 34, 36, wire 40 to upper armature brush 41, through the motor armature, lower brush 50, wires 43, 42,- contacts 35, 33, wire 45., and field winding 46 to the negative main. The motor Wlll now rotate in one direction while the circuit remalns closed. If
the switch lever is moved to the left to bring the contacts 33, 34 in engagement with the contacts 37, 38, a circuit wvill be closed through the motor as follows. From the positive main through the wire'44, contacts 34, 38, wire 43, to the lower brush 50,
through the motor armature, upper brush 41, wire 40', contacts 37, 33, wire 45, and field winding 46 to the negative main. As
the circuit through the motor armature is now reversed, the motor will run in the reverse direction. The reversing switch S may be connected to the motor, by a flexible cable or lamp cord 51 extending from the motor to any convenient point where it is desired to place the switch, the flexible cord' also permitting the switch to be moved from one place to another. An ordinary two-pole switch 52 may be placed in the circuit between .the reversing switch and the source of current supply.
The switch lever 31 is automatically centered by means of spring-pressed levers 53' pivoted at their lower ends concentrically with the lever 31, and having their upper ends bear-in against an intermediate por tion of the lever 31. Compression springs 54 between the casing 30 and lugs 55 carried by the levers 53 yieldingly hold the switch lever in its central position and return it tosuch position when released after operation. The operation of the hoistingmech'anism will be apparent, in view of the above description. \Vhen the reversing lever is moved in the right direction the motor will operate through the reduction " gearing 25, 26, 27 to run the drive gear 21 at a reduced speed and lift the receptacle R, which will more upwardly at half the peripheral speed of the drive gear 21. \Vhen the receptacle has been lifted above the surface of the walk, it may be removed and its contents emptied into a wagon at the curb-stone, and the receptacle again lowered by reversing the switch. The hook 22 may be used if desired to lower a receptacle simultaneously with the elevating of the receptacle R. 01, it may be'used in place of the hook 23 if a fgreate r speed is desired, the speed of the hook 22 being. double that of the hook 23. Also a counterweight may be attached to either hook while a load is attached to the other. i
' Although I have shown a construction embodying a preferred form of my invention, I do not wish to be limited to the precise construction shown. as various changes in the details ofveous'truction and arrangement of parts might obviously be made by those skilled in the art without departing from the spirit and scope of the invention.-
