Improvement in Sand-Blast Apparatus, of-
which the following is a specification.
This invention relates to a sand blast apparatus designed more especially for redressing the discolored stone of buildings and other fixed objects of stone, such as monuments."
The principal object of my invention is the provision of an inexpensive apparatus of this character which can be conveniently shifted along the side of the building, or other object to be dressed, as the work advances, as well as be moved vertically for bringing the apparatus adjacent to the stone to be dressed;
A further object of the invention is to provide an efficient guard for preventing the rebounding sand from scattering and striking the face of the operator and for gathering the spent. sand so as to avoid undue waste.
In the accompanying drawings: Figure 1 is a perspective view of my improved sand blast apparatus applied to a building, the apparatus being shown adjusted for operating upon the entablature of the portico Fig. 2 is a longitudinal section, on an enlarged scale, of the blast nozzle and the sand guard. Fig. 3 is a front view of the sandguard.
Like letters of reference refer to like parts in the several figures.
A represents a rotary blower or other suitable blast delivery de'vice. A .rigid air pipe 12 preferably extends from the'blast spout of the blower'to the' vicinity of the work to be redressed.
C is a blast nozzle which'is connected with the rigid air pipeb by a hose or flexible pipe 01. E is a sand hopper or receptacle, and eis a supply pipe whereby sand is conductedfrom the hopper to the blast nozzle. This supply pipe is provided with a'short tube or nozzle 6' which is inclined toward the delivery end of the nozzle and which preferably projects a short distance into the nozzle, as shown in Fig. 2. The sand hopper is arranged to move horizontally along the building or other object to be operated upon, so that the hopper as well as the blast nozzle may be shifted as the work progresses. For this purpose, the hopper is supported by a truck or carriage moving upon'a track, arranged adjacent to the building or other object. In the construction shown in the drawings, the hopper is suspended from atrolley or wheelf moving upon an overhead wire f, extending along the building and supported by brackets projecting from the windows of the building; but the wire may be supported by any other suitable means if desired. The sand hopper is thus free to follow the blast nozzle as the work advances.
In order to permit the sand hopper to be raised or lowered in accordance with the elevation of the work, it is made vertically movable. An ordinary tackle, consisting of the rope g and pulleys g, is preferably employed for this purpose, the upper pulley of the-tackle being suspended from the trolley and the sand hopper being suspended from the lower pulley, as shown.
The operator moves the blast nozzle over the work to be redressed, and thesand which is rapidly projected against the work by the blast cuts the surface of the stone, in a well known manner, removing its discolored face and giving it the appearance of newly-dressed stone.
H represents a guard applied to the delivery end of the blast nozzle for preventing the reboun ing sand from flying into the face of the operator. This guard consists of a flaring hood of gauze, cheese cloth, or other material which is sufficiently transparent to permit the operator to look through it and observe the action of the sand blast. The hood is supported by an internal open frame, consisting preferably of a volute spring h which is secured at its small end to the delivery end of the blast nozzle. This construction enables the guard to yield'or collapse in pressing it against the building and thus permits the operator to direct the blast closer to the surface to be redressed, this feature being especially desirable for reaching depressed surfaces. The guard also serves tocatch and collect the spent sand, and for the purpose of dis charging such sand from the guard, the same is provided at its lower end with a discharge spout 72/ through which the sandis delivered into a pail or other receptacle i placed underneath it.
My improved apparatus may be used for redressing various kinds of stone work. When the same is used for redressing isolated objects, such as monuments, the trolley wire or track may be stretched between two upright frames or supports, erected adjacent to the monument.
The apparatus, while useful for redressing all kinds of stone work, is particularly desirable for harmonizing the stone work of buildings to which additions are made some time after the erection of the original structure, especially buildings of brown stone, in which the contrast between the old and the new stone is sometimes so marked as to deter persons contemplating additions to such buildings, from doing so. By the employment of my apparatus, the stone Work of an old structure can, at comparatively small cost, be redressed to correspond to the new stonework of any additions.
I claim as my invention- 1. In a sand blast apparatus the combination with a horizontal track or wire arranged adjacent to the building or other object to be treated, of a portable sand hopper supported by said track or wire and a blast nozzle connected with said hopper, substantially as set forth.
2. In a sand blast apparatus, the combination with an overhead trolley wire or track, supported adjacent to the building or other object to be treated, of a wheel or trolley running upon said wire or track, a sand hopper suspended from said wheel or trolley, and a blast nozzle connected with said hopper and provided with a transparent sand guard, substantially as set forth.
3. In a sand blast apparatus, a blast nozzle provided with a contraotible transparent sand guard, substantially as set forth.
4. In a sand blast apparatus, a blast nozzle provided at its delivery end with aguard consisting of a volute supporting spring and a flexible transparent covering, substantially as set forth.
.Witness my hand this 20th day of March,
