Application area news, 1914. serial no. 851,763.
- respectively, have mvented certain new and useful Improvements in Fluid-Pressure- Operated Combined Brushes and. Scrapers, of which the following is a specification.
This invention has reference to those brushes and scrapers or the like which are arranged as hand tools, and are operated by compressed air-or steam or other fluid pressure and are used for cleaning various 7 surfaces such as the surfaces of coppers used in breweries and distilleries, the surfaces of gas holders, stone work, ships bottoms, the interior of tubes such as the interior of locomotive or other fire tube boilers and the tubes of water tube boilers and other surfaces which can be cleaned with a rapidly reciprocating brush or scraper.
According to the present invention the sliding block or plates upon which is mounted the scraper and brush is operated by a piston which reciprocates within a cylinder, the scraper and brush being so mounted and arranged that when the device is in use on a surface, it can first be held so that the scraper operates on the surface and scrapes dirt or rust or other foreign matter from the same, and then the tool can be reversed so that the surface can be finished by being operated upon by the brush. It is found in practice that when the said tool is in operation it works more advantageously if he handle to which the cylinder is applied is held loosely by the operator so that the hole or port communicating with a hole or port leading to the cylinder so that as the cylinder vibrates-on this extension the said ports remain in communication for the supply of an or other fluid pressure to the cylinder. Coiled wire or other springs are employed between the ends of the lug on the cylinder and collars on the handle, to
maintainthe cylinder in its normal position.
The fore part of the handle stem orextension projects beyond the front end of the cylinder and is by preference made with a knob or projection by which the brush can be pressed on to the surface while the other part of the handle is held by the operators other hand, the said knobbed projection also serving to turn the handle stem to connect or dlsconnect the ports in the stem and in the cylinder to control the operations of the tool.
Our invention will now be described with reference to the accompanying drawings wherein like reference letters indicate like parts in the several views.
Figure 1 is a part sectional side elevation of our invention; F ig. 2 is a part sectional elevation on line X X of Fig. 1; Fig. 3 is a part sectional plan on line Y Y of Fig. 1; Fig. 4c is a sectional elevation of part of Fig. 1, illustrating by comparison with Fig.
1, the stroke of the piston and of the parts on line Z Z of Fig. 1.
The tubular handle 1 has a screwed nipple 2 which is connected to a flexible tube through which the compressed air, steam or other fluid pressure is admitted to the to'ol, the other end of the handle 1 is formed with a tubular stem or extension 3. Slidably mounted on the tubular stem or extension 3 of the handle 1 is a cylinder 4 having formed therewith lugs, 5, 6, 7, the lug 5 having a longitudinal circular opening 8 there through in which the stem or extension 3 is slidably mounted. Longitudinal circular openings are also provided in the lugs 6, 7 in which are fixed guide rods 9 screwed at their lower extremities, and a -plate 10 forming the base of the cylinder 4 is secured to the cylinder casing by means of the nuts 11 screwed on the rods 9. Formed in the extension 3 is a slot or port 12 which is in communication with a hole or port 13 in the cylinder 4, the fluid pressure being admitted to the cylinder up the tubular stem and, through the ports 12 and 13. Within the cylinder 4 is a piston 11 adapted to receive fluid pressure exteriorly and interiorly,'according to the position of the piston as will be hereinafter more fully exp ained.
Secured to a cylindrical extension 15 of the piston 14 are two plates 16, 16 adapted to slide on the guide rods. 9, the plates are secured together and to the scraper 17 and brush 18 by means of two screwed shanks 19, 19 andnuts 20, 20 in such manner that the reciprocations of the piston are communicated to the scraper 17 and the brush 18. The plates 16, 16 rest, upon the flange 21 of the piston, and a collar 22 on the end of the cylindrical extension 15 abuts over the upper ends of the said platesso as to insure the movements of the piston being commu-.
nicated to the scraper and brush. Secured to the cylinder base plate 10 is a leaf spring 23 which is arranged to bear against flats formed on the collar 35 of the handle 1 so as to retain the handle in determined positions according to the amount of fluid pressure being admitted to the cylinder. Disposed at either end of the cylinder lug 5 are coil springs 24 and 25 which are adapted to maintain the cylinder in its normal position while at the same time permitting the cylinder to vibrate slightly under the influence of the reciprocations of the piston, for the purpose of reducing shock to the operator and insuring a more effective use of the tool. To the upper or forward extremity 26 of the stem or'extension 3 is secured a knobbed projection 27 which is mounted on the extremity 26 and secured thereto by means of a nut 28. The object of the said knobbed projection is to aid in guiding the tool while in operation, and by pressure thereon to cause the brush 18 to exert a greater pressure upon the surface being treated, and is also for the purpose of turning the stem 3 and handle 1 to regulate or cut off the supply of fluid pressure to the cylinder. I
The piston 14 is provided with ports 31 for admission of the fluid pressure to the interior of the piston, the operation of the piston being as follows :Assuming the piston to be in the position illustrated in Fig.
1, that is at the bottom of its stroke, fluid pressure is admitted from the tubular handle and stem or extension through the port 12 and cylinder port 13 into the annular recess 30 and through the ports 31 into the interior ,of the piston 14, owing to the interior surface area of the piston 14 being greater than the exterior surface area thereof, the fluid pressure forces the piston upward together with the scraper and brush secured thereto, until it reaches a position slightly beyond that seen in Fig. 4:, which illustrates the position of the piston just 13 is exerting a pressure upon the exterior of the piston 14; and forces the piston down again to the position seen in Fig. 1 when the cycle of operations is repeated. The reciprocations of the piston are approximately from 2000 to 3000 per minute.
The scraper 17 has a beveled edge 33 to insure more effective operation thereof, and is so positioned and arranged in conjunction with the brush that either the scraper 17 or brush 18 can be employed as desired. The brush 18 in the construction illustrated is mounted in a channel section bracket 31 which is secured to the scraper 17 by screws.
What we claim as our intention and desire to secure by Letters Patent is 1. A fluid pressure operated combined brush and scraper for cleaning surfaces, comprising in combination an edged scraper, a brush connected to one face of said scraper, a piston connected to said scraper and brush, a cylinder containing said piston, means for introducin fluid pressure to said piston and cylinder For the purpose of rapidly reciprocating the piston and simultaneously reciprocating the scraper and the brush.
2. A fluid pressure operated combined brush and scraper for cleaning surfaces, comprising in combination a flat section scraper having a beveled edge. a brush rigidly secured to one face of said scraper, a piston connected to said brush and scraper, a cylinder containing said piston, and means for rapidly reciprocating the piston.
3. A fluid pressure operated combined brush and scraper for cleaning surfaces, comprising in combination a scraper and a brush for alternate use, a piston connected to said brush and scraper, a cylinder containing said piston, means for introducing fluid pressure to said piston and cylinder for the purpose of rapidly reciprocating the piston, a tubular stem or handle through 1,122,781 &
