Application November 8, 1955, Serial No. 545,678

12 Claims. ((31.118-301) This application discloses and claims subject matter disclosed in my prior copending application Serial No. 488,175, filed on February 9, 1955, and entitled Adaptable Paint Spray Shield, which has now become abancloned and also discloses subject matter in addition thereto and is a continuation-in-part of said application.

This invention relates to a flexible spray gun attachment and to a spray device for coating or painting a wall surface comprising, in combination, a spray gun and said flexible spray gun attachment which is removably attached to said spray gun for spraying a predetermined confined surface area of the wall to be coated or sprayed without using masking tape on those wall portions not to be coated or painted and without moving said attachment from its position while that predetermined confined wall surface area is being coated or painted.

Copending with this application is my application Serial No. 545,679, filed on November 8, 1955, entitled, A Spray Device and a Spray Gun Attachment Which. is a Component Thereof, wherein the spray gun is fixed at all times with respect to the shield.

Spray guns have of late found widespread use in the coating or painting of wall surfaces and, in. areas in which painting or coating labor costs have been prohibitive, spray painting methods of both inside and outside wall surfaces has replaced the brush painting methods. However, in using spray painting methods it has been necessary to use masking tape and paper to cover those surfaces adjacent to the walls to be spray-coated or spraypainted in view of the fact that the paint spray escapes into the surrounding atmosphere and deposits upon surfaces not desired to be coated or painted. Also, in coating or painting wall surface areas directly adjacent other wall surfaces, including ceiling surfaces, the spray gun operator has found it necessary to mask one wall surface or window frame or door frame, as the case may be, before spray painting the required Wall surface area.

Various types of shielding devices have been introduced by other workers in the art for doing away with masking tapes or papers or other selective covering means. However, in each one of these cases, a very serious problem is presented, namely, the spray gun and the shielding device attached thereto must move simultaneously at all times during the spray-painting or coating operation with the result that that portion of the Wall surface area to be spray-painted directly adjacent to the wall surface not required to be painted does not receive the paint or coating material as desired and as required. For example, in a situation in which it is desired to coat or paint a wall surface with one colored material and a ceiling surface with another colored material it is im possible, with presently known shielding devices, to get a perfect line of demarcation at the points where the ceiling joins-the adjacent wall for the simple reason that, in all presently known spray devices having a shielding means, the spray gun, once either fixedly or removably attached to the structure including the shielding means, as the case may be, cannot move with respect to the shielding means abutting the wall surface to be coated or painted, and both the shielding means and the gun must be moved simultaneously. In other words, the shielding means of the spray gun attachments, of presently known spray devices are not flexibly mounted with respect to the spray gun and do not have any means in combination therewith for allowing the spray gun to be moved or swung on a single plane and/or on a plurality of planes without the accompanying or simultaneous movement of the shielding means along the wall surface which it abuts. To obtain a perfect line of demarcation, at the points where adjacent walls meet, with presently known spray devices which include shielding means it is necessary to use other and additional masking surface confining means, such as tapes and masking papers or, in some cases, to use complicated and expen sive spray devices.

With the spray device and the flexible spray gun attachment, including the shielding means, of my invention, the shielding means or member can be placed against a wall to confine a predetermined surface area of the wall, said area being especially directly adjacent to an adjoining wall and/or ceiling and/or frame portion of a door or window, and the wall surface area confined by said shielding means can be sprayed with coating material in such a manner that all portions of the predetermined confined surface urea will be effectively covered by the coating material and a perfect demarcation line will be obtained between the confined surface area and the directly adjoining portion of the directly adjacent wall or surface or frame. The effective coverage of all portions of the predetermined wall surface area of the wall and the simultaneous formation of the said perfect line of demarcation are possible because of the fact that the spray gun attachment shielding means can be held firmly in an abutting relationship with the wall while the spray gun is swung or moved in a single plane and/or in a plurality of planes which are horizontal, vertical, and/or inclined with respect to the wall surface to be covered with coating material. The aforementioned results obtainable for the first time with the structures of. my invention do not require any expensive and complicated components for positioning the spray gun with respect to the attachment, including the shieldingmeans.

An object of this invention is to provide a spray gun attachment, including a shielding means, capable of being removably attached to a spray gun for spraying a confined surface area of a wall, said attachment being of such construction and including a combination of component parts that the spray gun attached thereto can. be moved or swung in a single plane and/ or in a plurality of planes which are horizontal, vertical, and/or inclined with respect to the confined surface area to be spraycoated without using masking, tapes or papers to cover the surface areas not to be coated and directly adjacent to said confined area and without moving the shielding means abutting the confined wall surface area to be covered, whereby a perfect line of demarcation can be obtained between. the wall surface area being spray-coated and a wall or ceiling or frame directly adjacent thereto at the points at which said wall to be sprayed and said adjacent wall or ceiling or frame meet.

A further object of this invention is to provide a spray device comprising, in combination, a spray gun and a 'spray gun attachment, including a shielding means, re

movably attached thereto for spraying a confined surface area of a wall, said attachment being of such construction and including a combination of component parts that the spray gun so attached thereto can be moved or, swung in a single plane and/or in a plurality of planes which are horizontal, vertical, and/or inclined with respect to the confined surface area to be spray-coated without using masking tapes or papers to cover the surface areas not to be coated and directly adjacent to said confined area and without moving the shielding means abutting the confined wall surface area to be covered, whereby a perfect line of demarcation can be obtained between the wall surface area being spray-coated and a wall or ceiling or frame directly adjacent thereto at the points at which said wall to be sprayed and said adjacent wall or ceiling or frame meet.

More specifically, there is provided a spray gun I having attached at the barrel 2 thereof a clamping member 3 for receiving

prongs

4, 4 of the spray gun attachment including a shielding member. The clamping member 3 can be of any configuration depending upon the type of spray gun utilized, and the shapes of said member 3 and the spray gun and its barrel are merely shown here for purposes of illustration, and said specific configurations form no part of my invention. The spray gun attachment of each embodiment here described comprises tension spring members for positioning the attaching means of the respective spray gun attachment and the spray gun and for enabling the operator to move or swing the spray gun in one plane and/or a plurality of planes, as the case may be, without having to move the shielding means abutting the wall.

Referring now to the embodiment of Figures 1 and 4, the spray gun attachment 5 comprises a shielding memher 6 having

wall members

7, 8, and 9. Wall members 8 and 9 are substantially parallel to each other and substantially perpendicular to wall member 7, as shown. Wall members 8 and 9 have flange portions 10 and 11, respectively, as shown, and wall 7 has flange portion 12, as shown, which has a rectangular cutout 14 to receive the sliding member 15. Wall member 7 has a slot 13 therethrough as shown clearly in Figure 2, and fixedly attached to the sliding member 15 are

lugs

17, 17, as shown in Figures 1 and 4. Positioned on the top wall 7 is washer plate member 18 which has therethrough a slot 19.

studs

17, 17, as shown, said studs passing through the slot 13 of wall 7 and the slot 19 of washer member 18 to fixedly hold the sliding member in a predetermined position with respect to wall 7, as shown. The slots 13 and 19 of the Wall 7 and the washer plate member 18, respectively, can be replaced by the

holes

16, 16, 16,16 and the holes 21, 21, 21, 21, respectively, as shown clearly in Figure 3. Sliding member 15 has

integral therewith flanges

23, 23, as shown. Connected to sliding member 15, and preferably integral therewith, as shown, is bracket support member 22 comprising a portion 24 substantially perpendicular to member 15. Connected to member 24, and preferably integral therewith, is member 25 which forms an angle, as shown, with a plane A which is inclined with respect to wall

B. Flange portions

26, 26 are connected to member 22 as shown, and

flange portions

27, 27 are connected to member 25, as shown. Movably attached to member 25 is a connecting member 28 which comprises a semicircular portion 29 and

flange members

30, 30, as shown. The member 28 is loosely connected to the member 25 by means of a bolt 31 which passes through the hole 32 in the topmost portion of portion 29 of member 28 and which is held loosely positioned by means of a nut 33. In

flange members

27, 27 are grommeted

holes

34, 34, and in

flange members

30, 30 are

holes

35, 35, as shown. Tension springs 36, 36 are each positioned at the respective connecting ends in said

holes

34 and 35, as shown, and each one of said springs 36, 36 exerts a pulling action against the respective members connected thereby positioning said members and the spray gun attached thereto. The

prong members

4, 4 are removably squeeze fitted into holes 37 of clamping member 3 which is fitted over the barrel of the spray gun.

In flange members 10 and 11 integral with walls 8 and 9, respectively, of the shielding member 6 are grommeted holes 38, 38 to receive the ends of tension springs 39, 39, as shown in Figure 5, which illustrates another embodiment of my invention. Instead of tension spring members 36, 36 being positioned between member 25, at the

flanges

27, 27 thereof, and

flanges

30, 30, tension spring members 39, 39 can be positioned with their connecting ends being attached tothe shielding member at holes 38, 38, as shown in Figure 5. In this embodiment also, each of the tension springs 39, 39 exerts a pulling action against the respective members connected thereby positioning said members and the spray gun attached thereto.

As is clearly shown in Figures 1 and 4, the

flange members

30, 30 are parallel to the member 25 and are on a plane C extending from the points at which the

prongs

4, 4 are attached thereto to the uppermost points of said wall 7 at which points wall 7 abuts the surface of Wall E to be coated. The inclusion of the sliding member 15 in my device makes it possible to use my spray gun attachment for any type of spray gun since the member 15 can be so positioned that the nozzle of any type of spray gun will always be on such plane and will be pointed substantially at a point at which the uppermost 1 portion of the shielding member wall abuts the wall surface to be coated. Also used here are bracing members 48 welded to the

flanges

23, 26, and 27, as shown in Figures 1 and 4. i i I ass-2,093

Here are illustrated the edges 65 and 66 of walls 8 and 9, respectively and the position of wall 8 when abutting the wall surface to be coated. It is to be particularly noted that the entire spray device including the spray gun and the spray gun attachment will be at an incline with respect to the wall to be coated during the coating of the wall surface area of wall B confined by the shield member of the device.

Also, to enable the operator to move the shielding members 6 and 41 more freely ball bearing members 67 can bemounted at the corners of walls 8 and 9 abutting the wall surface, as shown in Figure 1.

Figure 14 illustrates another embodiment of my invention. Here the spray gun attachment 8d comprises a shielding member 8i having wall members 82, $3, and 84. Wall members 82 and 334 are substantially parallel to each other and substantially perpendicular to wall member 83, as shown.

Wail members

32 and 34 have flange portions and 36, as shown, and wall member 83 has flange portion 37, as shown. Wall member 63 has fixedly attached to the top portion thereof and substantially equidistant from

wall members

82 and 84 the clamping member 83 having a threaded hole therethrough at the central. point of the raised portion and a nut 89 coinciding with said hole and fixedly attached to the raised portion of the clamping member 88 to receive a set screw 189. A sliding member 90 is positioned by extending it through clamping member 88 and tightening set screw 89 against it. Connected to sliding member 96, and preferably integral therewith, as shown, is bracket support member 91 comprising an angularly disposed portion 92. Connected to member 92, and preferably integral therewith, is member 93 which forms an angle, as shown, with a plane A which is inclined with respect to wall B and which falls on a plane parallel to plane C, as shown. Movably attached to member E93 is a connecting member 9-4 similar to member 28 of the embodiment of Figure l, which comprises a semi-circular portion $5 and

flange members

96, 96, as shown. The member 94 is loosely and movably connected to member 93 by means of a bolt or stud 97 which passes through the hole 98 in the topmost portion of portion of connecting member 94 and which is held loosely and movably positioned in hole 98 by means of a bearing member 99 coinciding with hole 98 and fixedly attached to member 93 and substantially perpendicular thereto, as shown. In flange members 96, are holes lltlil, we, as shown, and in angularly disposed portion 92 of bracket support member are holes ltlll, ltll, as shown. "ension springs ltllt, ltlil are each positioned at the respective connecting ends in said holes 10% and till, as shown, and each one of said

springs

102, 102 exerts a pulling action against the respective members connected thereby positioninr said members and the spray gun attached thereto. The

prong members

103, 103 are fixedly attached to the

flange members

96, 96 and are substantially perpendicular thereto, as shown, for engagement with the holes or receiving membernrs of a clamping member which is fitted about the barrel of a spray gun to be attached thereto. It is to be particularly noted that the

walls

82 and 84 are similar to the walls 8 and 9 of Figure 1.

My spray devices comprising, in combination, the spray gun and spray gun attachment are used in the following manner:

In using the spray device of Figure l the sliding member is first positioned in such a manner that the nozzle of the spray gun used is on a plane, here designated as C, meeting the edge 63 at all points thereof, said edge abutting the wall B. The edges 65 and 66 of walls 3 and 9, respectively, of the shielding member 6 are also positioned against the wall, and the operator starts the spraying operation. During the coating operation, the operator swings the spray gun l which is attached to the spray gun attachment 5, including the shielding member 6, in the direction of the arrows K, K, and thereby obtains an evenly coated surface area confined by the said shielding member and at the same time obtains a perfeet line of demarcation between the walls B and D and the ceiling F. To prevent the coating material from covering the floor surface, the drip pan 4% may he attached, as clearly shown in the appended drawings. In place of the spray gun attachment 6 of Figure 1, the spray gun attachment ll. of Figure 6 can be used, and here the spray gun l. is capable of being swung or moved in all planes, as desired by the operator, because of the use of the tension spring 45 instead of the sliding member l5 and its associated component parts illustrated in Figure 1. The shielding members 46 and 47 are utilized in place of members 6 and 41 wherever wall obstructions and/or wall switchboxes present themselves or wherever two walls perpendicular to each other are to be covered with the same colored coating material. The spray gun attachment of Figure 10 including the shielding member 58 and the shield member 56 of Figure 11 are used where arched portions of walls are to be coated. With the structure comprising the ring 61 and the tension springs 60, 60, 60, 60 of Figure 10, the spray gun attached thereto at the prongs 62, 62 can be swung in all planes by the operator. The spray gun attachment 80 of Figure 14 dilfers from that of Figure 1 in the bracket support members used. In each case, the bracket members may be bent to compensate for the change in position attained by moving the sliding portion to or from the wall. The bending is done at the points where the respective ends of the sliding member and the bracket support meet.

The spray gun attachments here disclosed are preferably made of aluminum, which, as is well known, can be easily worked, and by aluminum is meant aluminum and its alloys.

From the foregoing subject matter, it is seen that I have provided a spray device and spray gun attachments, each including a shielding means, whereby perfect lines of demarcation can be obtained between adjoining walls at the points at which they meet and at the same time a confined surface area of a wall can be sprayed, thereby preventing the waste of coating material and at the same time obviating the requirement of covering surfaces not to be coated with masking tapes or papers.

Many alterations and changes may be made without departing from the spirit and scope of this invention which is set forth in the appended claims which are to be construed as broadly as possible in view of the prior art.
