Briese, Galveston, Tex., assignor to Todd Shipyards Corporation, New York, N. Y., a corporation of New York Application December 2,1, 1948, Serial No. 66,487 k1 claim. I(Cl. .2s-81) This invention relates to a deck sealer, and more particularly to a machine for removing scale, paint, and other deposits from the deck of a ship. While primarily intended for scalingV a ship deck, it is to be understood that the invention is equally useful in any situation requiring the scaling or chipping of a surface of large area.
A general object of this invention is to provide a simple machine actuated by compressed fluid for performing a scaling operation.
Another object is to provide a deck sealer hav ing a plurality of sealer heads having scaling tools whose operation is controlled by a single conveniently accessible means.
A further object of the invention is to provide a novel arrangement of scaling tools, whereby a broad surface may be scaled in a single pass of the machine.
Another object is to provide novel means for mounting the sealer heads on the frame of the machine, whereby shock and vibration, due to the reciprocation of the scaling tools, will be reduced to a minimum.
A further object is to provide novel handle means for both propelling the deck sealer machine over the surface of the deck, and also controlling the supply of fluid to the sealer heads.
Further objects and advantages of the invention will appear in the following description and in the appended drawings, wherein is illustrated a preferred embodiment of the invention. The broad scope of the invention is pointed out in the appended claim.
In the accompanying drawings, wherein like numerals refer to like parts throughout:
Figure l is a top plan view of the deck sealer in accordance with this invention.
Figure 2 is a partial sectional view taken on the line 2 2 of Figure l.
Figure 3 is a front elevation as viewed from the right hand side of Figure l.
Figure 4 is a bottom plan view, and
Figure 5 is a partial sectional view taken on the line 5--5 in Figure 4.
Referring to the drawings, II indicates the frame of the deck scaler and is shown in the form of a ilat horizontal plate. Along each of two opposite edges the frame II has downwardly depending anges I2 and I3, as best seen in Figures 3 and 4. At one forward corner of the frame II and rigidly secured to the flange I2 is a wheel support I4. At the other forward corner of the frame II and rigidly secured to the flange I3 is a wheel support I5. Centrally of the rear edge of the frame II is a wheel support I6. The supports I4, I5 and I6 each have a pair of downwardly depending lugs or flanges I'I, and a roller 2 or wheel I3 is rotatably mounted therein b means of a headed pin 23 locked in position by a cotter key 24.
Rigidly secured to the lower surface of the frame II and adjacent the rear edge thereof is a long tubular manifold I9. As shown in Figure 4, the manifold has closure caps 2| at each end and is pivotally secured to the frame II within trunnions 20. v
Within the lower surface of frame II a plurality of somewhat elliptical recesses 34 are formed, and mounted within the recesses 34 are cup-like shock absorbers 35 composed of rubber or other similarly resilient material. Mounted within the shock absorbers 35 are the scaler heads 32, as best shown in Figure 5. v v
The scaler heads 32 may be of any conventional type, and since their internal construction is well known to those skilled in the art, the details of such construction will not be described'herein, except to state briefly that the sealer heads 32 have a plurality of scaling tools 33 depending therefrom as best shown in Figure 3. The particular sealer heads 32 shown in this illustration of the invention are known as the Oldham type, and each has three scaling tools 33 arranged in a straight horizontal row; The scaling tools 33 are caused toreciprocate vertically so as to chip or scale paint and other deposits from the surface, as is well known in the art. It' is to be understood that the specific type and construction of scaler heads 32 and scaling tools33 form no part of this invention and any equivalent type of sealer head may be substituted for the Oldham type disclosed herein.
In order to secure the scaler heads 32 and cup- .like shock absorbers 35 within the recesses 34,
a plurality of U-shaped tie bolts 33 may be employed. Each of the tie bolts 35 comprises a pair of vertical legs 3l connected by a lower base portion 38, as best shown in Figure 2. The vertical legs extend upwardly through the frame II and are secured to the frame II by means of washers 48 and nuts 3-9. The lower or bight portions 38 of the U-shaped tie boltsV 36 engage the lower surfaces of the sealer heads 32 so as to draw said heads 32 and the shock absorbers 35 up into the recesses 34 and securely hold them in place therein. Two tie bolts 36 are preferably employed for each scaling head, one of the tie bolts extending between two adjacent scaling tools 33.
The relative arrangement and location of the scaler heads 32 will be noted. A row or series of Scaler heads 32 is disposed perpendicular to the forward direction of movement of the deck scal'er (which is to the right as viewedin Figure l). The sealer heads 32 of said forward row are ing tools moving along parallel paths.
suitably spaced and a second row of sealer heads 32, parallel to the rst row and perpendicular to the direction of forward movement of the deck sealer, is located rearwardly of said first row. Each o' the sealer heads 32 of the second row is located opposite the space between two sealer heads of the first row. 1t will be thus seen that this overlapping relation enables a broad surface to be scaled in a single pass of the machine. The several scaling tools 33 of each sealer head 32 are equi-distantly spaced from one another. Furthermore, the scaling tools at the extreme ends of each sealer head of one row are spaced, in a direction transverse to the direction of movement ofthe deck sealer, from the adjacent scaling too1 in the other row a distance equal to the distance between the several scaling tools cf each head. 'In other werds, it will be seen in Figure 4 that the transverse offset distance between scarlu ing too1 33' and scaling tool 33" will be the same as the distance between sealing tool 33 and scaling tool 33". By this arrangement movement of the deck sealer will result in the several scal- The above-noted overlapping arrangement of the sealer heads 32 permits the several scaling tools 33 of the .different sealer heads 32 to be equidistantly spaced laterally of the machine and its movement.
Each scaling tool 33 will remove paint over an area of sufficient lateral extent that during Cil a single pass of the machine over a deck, it will remove all paint and scale within the area bounded by the two laterally outermost tools.
Extending rearwardly and horizontally from each of the sealer heads 32 is a metallic tube or duct 40. In alignment with these tubes 40, are
manifold discharge tubes BI, as shown in Figure 4. Leading from each of the manifold discharge tubes 3l to each of the tubes 4Q is a flexible hose 4 I.
Referring to Figure 2, a pipe 22 is secured to L the manifold I 9 and extends upwardly and rearwardly of the manifold I9 and has a valve conneetion 25 at its upper end. rIhe valve 25 is actuated by the handle 25. Extending from the valve 25 is a pipe 52 having at the upper end thereof a hollow cross-bar handle 21. As shown in Figure 1, the handle 21 has a closure cap 23 at one end and a hose 29 secured to the other end by means of a conventional hose clamp 32.
Operation It will be thus seen that the wheels I8 allow the frame Il to be rolled along the surface of a deck by means of the operator pushing or pulling on the cross-bar handle 21. may be connected to any suitable source of supply of compressed fluid or gas (not shown). It is to be understood that the term fluid as used in :this specification and the appended claim includes air, steam, water or any other gaseous or liquid fluid. The compressed fluid enters the hollow cross-bar handle 21, flows down through the pipe 52 and, assumingv that thevalve 25 has been opened by means` of handle 2B, the com- In addition to providing a simple effective means for supplying compressed uid to the manifold I9, the arrangement comprising pipes 22 and 52, valve 25, hollow cross-bar handle 21, and hose 29, also provides a convenient means for propelling the machine along the deck, and also a valve means conveniently accessible to the handle for controlling the operation of the sealer heads 32.
The above-described specific embodiment of the invention is intended to be merely illustrative, the scope of the invention being indicated by the appended claim.
I claim:
