Application May 20, 1931. Serial No. 538,767
1'7 Claims.
This invention relates to a machine for renovating facades of buildings. Heretofore all renovating work upon facades, such as washing, scrubbing, sand-blasting, etc., was performed by the utilization of scaffolding, and operatives doing the work manually or with the aid of suitable implements or devices while supported on the scaffolding, which character of work is well known to be dangerous, arduous, time consuming, costly, and often inefiicient.
The principal object of the invention is to provide a machine wherewith such work may be performed entirely automatically, without the use of scaffolding, and with an operative merely positioning the machine upon the building and adjusting it for the particular service required.
Another object is to provide a machine for such purpose, which will perform the renovating work conveniently, rapidly, economically, efliciently, and with perfect safety.
Other objects and advantages will hereinafter appear.
In the accompanying drawings,
Fig. 1 shows a side elevation of the machine.
Fig. 2 is a front elevation of the machine.
The renovating machine 1 is positioned for its operation upon the roof 2 of a building 3 adjacent its parapet 4. Said machine includes a base-frame 5 having suitable casters 6 for conveniently propelling the machine to its required position. To the frame 5 are secured posts '7 having mounted therein bearings 8 for an axle 9 of a rotatable sheave 10 carrying a pair of suitable hoisting cables 11. The posts 7 carry cantilever beams 12 which project therefrom over the facade of the building, and in the intersection of said posts and beams and near the extremities of the latter are mounted conveying pulleys 13, 14, as shown. From the sheave 10 the cables 11 are conveyed upwardly to the pulleys 13, over to the pulley 14, and from the latter the cables are suspended toward the sidewalk and in front of the facade 15 of the building. Upon the terminals of the cables 11 is suspended, by means of rings 16, a framing 17 carrying a motor 18, to the shaft of which is fastened a chuck 19 to which is removably clutched a wire brush 20, or any other suitable cleaning or renovating device. To the rear side of the motor is secured a framing 21, to which are tied a pair of supporting cables 22 that are in turn spliced to the cables 11 at 23, whereby the motor 18 and brush 20 are sustained in steadied horizontal and vertical positions respectively, and the brush 20 is properly aligned with the facade. A crank 24 and ratchet gear 25 are keyed upon the axle 9, and a coopcrating pawl 26 for said gear is carried by a. bracket 27 secured to one of the posts '7, by which means the sheave 10 may be rotated to elevate, lower, and maintain at any required position the motor 18 with the brush 20.
As certain mate-rials are often required to be used in conjunction with renovating processes, such as abrasives, cleansers, sand-blasts, etc., or such mediums as compressed air or liquid, the same may be fed to the work from the roof through a hose 28, which passes over conveying rollers 29, mounted in the posts '7 and beams 12, and is provided with a nozzle 30 located over and near to the brush 20. In order to retain the nozzle 30 at its proper working location, the terminal of the hose passes through a hole 31a of a clustering plate 31, through another hole 31?) of which also pass the cables 11, which plate thus binds the nozzle to said cables and holds it in requisite proximity to the work. For feeding current to the motor 18, an electric cable 32 is similarly conveyed from the roof, over rollers 33 mounted in the posts '7 and beams 12, through a hole 31p of the plate 31, and to the motor.
The posts 7 are split at 34, and channelled extension-plates 35, having slots 36, are joined thereto by bolts 37 that pass through said slots and thread into the posts, in which manner the beams 12 and conveying pulleys 13, 14 may be adjusted to any'elevated or lowered position relatively to any obstructing parapet 4. In the same manner the beams 12 are split at 38, and are similarly provided with slotted channelled plates 39 and bolts 40, for laterally adjusting the distance between pulleys 13, 14 to clear the suspension cables 11 of any cornice or other overhanging projection upon the facade of the building. The motor-shaft 31 is split at 42, and a sleeve 43 telescopes thereover and is secured thereto with setscrews 44 that thread therethrough and against the shaft portions, in which manner the shaft 41 may be adjusted in longitudinal extension to any increase or decrease of distance that may be required between the cables 11 and the facade 15 or the face of the brush 20, due to any overhanging obstruction upon the facade.
When renovating work is to be performed upon a building, the machine is positioned upon the roof against its parapet 4, the height and extensions of beam 12 and pulleys 13, 14 are adjusted with the bolts 37, 40 to conform to prevailing conditions, the current is turned on to rotate the brush 20, and the requisite material is fed to the nozzle 30. While the brush is thus working with said material to renovate the topmost initial portion of the facade it may be gradually lowered together with the motor and nozzle toward the sidewalk, by turning of the crank 24, and thereby advanced to renovate a vertical band or area corresponding to the height of the building. Thereafter the brush and its appurtenances may be hoisted back to the top of the building and the entire machine shifted laterally so as to bring the face of the brush against a portion of the facade adjacent to the swath thereof last renovated, and the machine may be then again operated to renovate an adjacent similar area of the facade. In this manner the work may be continued until the renovation of the entire building'is completed. The extent of working pressure of the-brush 20 against the facade may be regulated by placing the machine nearer to or farther from the parapet 4.
A rope 45, secured to the framing 21, as shown, is suspended therefrom to the sidewalk, where it may be grasped by an operative, while the machine is performing the working operation, to therewith control the precise placement of the brush upon the facade, or to skip any required areas thereof, due to location of windows or other obstructions of the building.
Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
