8Clllms.'
My invention relates to painting devices and more particularly to a brush attachment for spray guns. My invention is particularly directed to a novel brush and mounting means providing for attachment to the usual and well-known spray guns used for spraying paint.
An object of my invention is to provide a novel and eflicient means to a spray gun for the brushing of the paint as it is sprayed from the gun.
Another object is the provision of a guard or shield for the diffused spray of paint coming from a spray gun, which guard or shield is of bristle material adapted for spreading the paint upon the surface to which the paint has been sprayed.
Another object is the provision of a simple and yet convenient means of attaching a brush to a spray gun. v
Another object is the provision for mounting brush bristles around four sides .of the nozzle of a spray gun whereby the brush bristles direct the paint being sprayed and also brush the material along the surface thus sprayed.
Another object and a fuller understanding of my invention may be had by referring to the following description and claims, taken in conjunction with the accompanying drawing in which:
Figure 1 is a side view of a spray gun with my brush attachment mounted thereto;
Figure 2 is a view taken through the brush of my device and looking in the direction of the arrows 22 of Figure 1;
Figure 3 is a detailed view illustrating the mounting of my device and is a cross-sectional view through the line of the arrows 3-4 of W- ure 1; and
Figure 4 is an exploded view of my brush at tachment removed from the spray gun and shows the brush member removed from the bracket member.
In the several views of the drawing, the reference character H denotes generally the spray gun. This spray gun is of the usual or orthodox type and has a body 12 and a pistol handle ll extending at an angle from the body portion 12. There is provided an air inlet 2! connected to the lower end of the pistol handle it and there is provided a paint or liquid inlet ll leading into the body i2 of the gun. A trigger It operates the valve mechanism of the gun in the usual manner. The upper end of the trigger I4 is forked to provide the forked end I5, the forked end I! Stride dling the body I! and the upper end of the forked end is of the trigger being pivotally carried by a bolt l1 extending throush the body of the sun.
A cylindersleeve It on the bolt ll engages in opposite holes formed in the forked end I! and thus the trigger ll pivots on the bolt l1 and sleeve It so that by reciprocating the lower end of the trigger H the valve mechanism of the gun is operated. The gun ii has a nozzle portion 3| at its forward end. This nozzle III is in the usual form having air and paint or liquid outlets arranged to provide a spray of paint or other liquid forwardly from the gun upon operation of the trigger it to its operating position.
The bracket member, denoted generally by the reference character It, is adapted to fit over, and be attached to, the spray gun. The bracket member I8 is preferably made of sheet metal such as light sheet steel and will flex slightly to adapt itself to engagement on the gun. The bracket member I8 has two spaced and generally parallel side walls which engage on the opposite sides of the spray gun. There is an upper portion lsof the spaced side walls which are on opposite sides of the body l2 of the spray gun and there is a lower portion 20 of the spaced side walls which are engaged on opposite sides of the pistol handle l3 of the spray gun. To generally conform to the outline of the gun the lower portion 20 of the bracket is extended at an angle to the upper portion is, the upper portion l9 thus fittingover the body of the gun and the lower portion 20 thus fitting along the pistol handle of the gun. The two spaced side walls of the bracket [8 are joined by a rear or back wall 2! along the rear edge of the lower portion 20 of the spaced side ally parallel to each dther. The rear wall 2| is somewhat curved or rcuate so as to provide a smooth and comfortable surface forthe hand of the operator holding the gun and brush attachments together. There is a slight spring in the curved rear wall H to permit the bracket to have its side walls slightly flexed in applying the bracket to the gun. The resiliency of the rear wall 21 and the bracket generally is set as to hold the bracket in snug and firm engagement on the gun after mounting.
The upper portion IQ of the two spaced walls has two aligned holes 25 which receive the bolt l'l carrying the trigger ll. The holes 25 are of a diameter to permit the bolt I! to extend through end by the rear wall 2i.
but are not of sumcient diameter permit the sleeve i6 to extend through. As shown in Figure 8 the side walls of the bracket are firmly clamped to the body l2 of the gun by the bolt il extending through the forked end l of the trigger, through the body l2 and through the upper portion I. of the spaced side walls of the bracket. To prevent binding of the trigger upon turning the wing nut 26 on the bolt i1 and drawing of the head 21 ofthe bolt I! inward, it is provided that the side walls I! are pressed inwardly upon the sleeve ll. Thus the bracket is tightly engaged to the spray gun body and yet the forked end is of trigger I4 is not tightly bound thereby and it may freely rotate on the shaft provided by the sleeve l6.
At the forward end, that is the end nearest the nozzle, of the two spaced side walls the outwardly extending walls 22 diverge outwardly at a right angle to the upper portion is of the bracket. The side walls of the bracket then bend at another right angle at the outer extreme of tl.e outwardly extending walls 22 to form the parallel clamping walls 23. Thus as seen in the several views of the drawing, and particularly in Figure 4 thereof, the bracket is comprises two identical portions spaced from each other and joined at one The clamping walls 23 may be moved slightly toward and away from each other as desired. The walls 23 are a continuation of the spaced side walls of the upper portion IS, the clamping walls 23 being spaced farther apart than the other parts of the bracketby reason of the outwardly extendingwall portions 22. The lower and inner portions of the outwardly extending walls 22 are cut away at 28 as indicated in Figures 2 and 4." The cut away portion 28 provides for the ready mounting of the bracket l8 over the body II and particularly for the slipping of the portions 22 over the nozzle 3| where the paint inlet 30 enters the gun body, the cut-away portion 28 accommodating the paint inlet 30 and the hose (not shown) attached thereto.
Two pairs of aligned holes 24 are provided in the parallel clamping walls 23, one pair of aligned holes 24 being in the upper portion and the other pair of aligned holes 24 being in the lower portion.
The brush member of my device, denoted generally by the reference character 33, is in a generally rectangular form in cross section. It also has a rectangular shaped open space therein, the open space being bounded on four sides by the body of the brush. The base of the brush is comprised of an outer rectangular shell 34, preferably made of sheet metal formed to the desired shape, and an inner rectangular shell 35, also preferably made of sheet metal formed to desired shape. The inner shell is somewhat smaller than the outer shell 34 and the ends of bristles are clamped or firmly bound between the inner and outer shells 34 and 35. A suitable mounting substance such as hard rubber or plastic embeds the inner ends of the bristles within the shells 34 and 35 so that the bristle portion 40 becomes firmly bound within the base formed by shells 34 and 35.
Two pairs of aligned holes 36 are provided in the brush member to extend through the opposite walls of the shells and confined bristle portions. The upper holes 36 in the brush member are in alignment with the upper holes 24 of the bracket member and the lower pair of holes 36 in the brush member are in alignment with the lower pair of holes 24 in the bracket member.
Two long bolts 31 having heads 38 and wing nuts 33 provide for the-clamping and securement of the brush members between and to the clamping walls 23 of the bracket member. The bolts 31 extend through the brush members and clamping walls 23 as indicated in the figures of the drawing, and by turning the wing nuts 39 down to draw the heads 33 inwardly the brush member is firmly anchored to the bracket member.
To assemble my brush attachment to a spray gun the bracket member is is moved forwardly against the back of the spray gun and the lower portion 20 of the bracket is pressed firmly upon the pistol handle i3 until the rear wall 2i engages the pistol handle iii. The upper portion 13 is thus on both sides of the body l2 and in loose engagement with the body' l2. The bolt II that carries the trigger i 4 is inserted to the position shown in Figure 3 and the win nut 26 tightened down. Thus the two side walls of the upper portion is are firmly anchored and secured to the body of the gun. By reason of the disposition of the sleeve l6 around the bolt ii, the wing nut 26 may be tightened down but the trigger i4 is not tightly bound thereby.
Next, the brush member 33 is placed in-position by moving the base of the brush member between the two opposite clamping walls 23 of the bracket. The longer sides of the rectangular shaped base of the brush member are placed adjacent the long clamping walls 23. Bolts 31 are then inserted through the aligned holes 24 and 36 and the wing nuts 39 applied and tightened down. The brush member is thus tightly clamped between and secured to the clamping walls 23 of the bracket i8. In this position the large rectangular open space in the bristle portion 40 of the brush member surrounds the .nozzle 3| of the spray gun. As seen in the drawing, the brush portion 40 forms a shieldor guard around four sides of the nozzle and acts to confine the spray discharged from the nozzle from spreading too far sidewards, i
To disassemble the device the process is repeated in reverse. The wing nuts 39 are removed and the bolts 31 withdrawn. The brush member is thus taken from the bracket. The bracket is removed from the gun by removing the wing nut 26 and withdrawing the bolt l1. By pulling back on the bracket it is disengaged from the spray gun and the entire device is thus disassembled from the gun.
It will be noted from the drawings and description, that this device permits the spray gun to be used in the usual manner to spray a surface and also permits the brush to brush across the sprayed surface in the usual manner. The brush bristles provide a shield to prevent widespread diifusion of the paint'spray. In operation it has been found that great advantages in operation in painting may be had by holding the device with the forward end of the bristles removed a short distance such as two or three inches from the surface being painted and moving the device parallel to the surface at the spaced position while spraying paint. Then after sufiicient paint has been applied to the surface by spraying, the gun is moved forwardly to bring the bristles in contact with the surface being painted andthe device moved back and forth along the surface to spread the paint with the bristles. This device combines the advantages of both a spray gun and brushes and permits both to be used substantially simultaneously. In outdoor painting such as painting a side of a house,
5 it has been found that the wide diffusion of. paint spray ordinarily makes paint spraying too difiicult and inconvenient for use, the spray being spread diffused around the surroundim atmosphere. However, with my device the spray is confined to a less local area, is directed to where application of paint is desired, and the paint may be brushed as and where needed.
It is understood of course that the word "paint as used in the description and claims covers any liquid or semi-liquid substance ordinarily sprayed or adapted to be sprayed from spray guns.
Although I have described my invention in its preferred form with a certain degree of particularity, it is understood that the present disclosure of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts may be resorted to without departing from the spirit and the scope oi the invention as hereinafter claimed.
