c. c. MEUTSCH DEVICE FOR SPRAYING UPHOLSTERY Filed May 24, 1928 2 Shts-Sheet 2 Patented Feb. 21, 1933 UNITED STATES CHARLES C. MEUTSCI-I, OF BUFFALO, NEW YORK DEVICE FOR SPRAYING UIPH OLSTERY Application filed m 24, 1929. Serial No. 280,197.

7 This invention relates to a device for spray ing upholstered furniture and more particularly to a system of pipes permanently concealed'in the upholstery of furniture and having a series of ports through which a fluid, for the extermination of moths andthe like,"is forced and sprayed into the upholstery. i

Upholsteredfurniture and particularly upholstered furniturewhich is covered with mohair is particularly subject to attacks of moths which destroy portions of the covering and necessitate recovering of the entire piece "of furniture in view of the fact that it is diflicult to match particular portions of the covering. Heretofore it has been attempted to spray furniture with a moth exterminating fluid from the exterior of the same. The moths, however, get into the breaks between the diiferent upholstered surfaces and make it extremely difficult to reach them by'a surface spraying. Ihe present invention, therefore, proposes a system of pipes which are concealed within the upholstery and are provided with a series of ports the entire length of the same, whereby the moth extermin ating fluid is sprayed into those parts'ofthe furniture where the moths are most likely to lodge, and also completely spray the upholstery from the interior thereof, thereby permeating the entire upholstering with the fumes of the moth exterminating fluid and also retaining the fumes within the upholstering for a considerable length of time. By this means only an occasional spraying is required.

One of the ob'ects of this invention is to provide a device of this character which is completely concealed within the upholstery when not in use and does not interfere with the comfortable-use of the piece of furniture. A further object is to provide such a device which can readily and quickly be brought into operative position and the spraying of the furniture accomplished thor- Q I oughlyand in a short time.

Afurther aim of this invention is to provide SllChttCl'GVltCG Wl1lCll has a reservoir for the storage of the. moth exterminating fluid 80 and in which it is only necessary to create" an air pressure on the top of the reservoir to force apart of thefluid contained therein through the pipe system toeifect a spraying of the upholstering.

A stillfurtherpurpose to so organize and arrange the pipe systemthat the spray will be discharged at the places in the upholstering where the mothsare most likely to lodge and lay their eggs.

Other aims are to provide a device which is light, compact and inexpensive and which. can readily be installed in furniture of standard design without substantial alteration thereof.

Figure 5 shows a pipe system, reservoirandfilling nozzle therefor which forms a unit which is adapted to be placed in furniture whichis completely.upholstered and ready for shipment. I V

Figure 6 shows a pump which is adapted for use in connection with the present inven-- tion, this pumpbeing actuated through movement derived from the persons'itting down in the chair for spraying a quantity of the moth exterminating fluid into the upholsterin The present invention is shown as applied to an overstuffed arm chair which in general comprises an uphostered spring supported seat an upholstered back 11; and two upholstered arms 12, the upholstering being arranged to provide breaks 13 between the arms and the seat and a break let between the back and the seat.

The chair frame which supports the upholstering and also carries the system of pipes and the reservoir of the present invention, as best shown in Figure 1, comprises two front posts 15, 15; two rear posts 16, 16; a front rail 1?, connecting the front posts; a back rail 18 connecting the lower ends of the back posts 16; side rails 19, 19, connecting the lower ends of the corresponding front and back posts; a back rail 20 connecting theupper ends of the back posts; a pair of armrails 21, 21, connecting the upper ends of the corresponding front and back posts; upholstering rails 22, 22, connecting the corresponding front and back posts and arranged between the arm rails 21 and the side rails 19 thereof; vertical bars 23, 23, extending between the upper and lower backrai's 20 and 19; and a horizontal back upholstering rail 2 between the vertical bars 23.

' The seat of the chair may be upholstered in any well-known manner, and as shown in Figures 2 and 3, webbing 25 is stretched between the lower front, side, and back rails and is secured to the underside thereof. The webbing supports a group of springs 26'which are housed within a burlap casing 27 which casing is suitably secured at its edges to the webbing. This casing is covered in the usual manner with a fibrous stuffing 28, such as moss, hair or the like and the stuffing is enclosed by thecover 29. The cover 29 for the seat, is secured at its front to the front rail 17 and at its sides to the side rails 19, as best shown in Figure 3. At its rear the cover 29 extends down and is secured to the back rail '18. At its center, as best shown in Figure 2, an opening 30 is left in the central part of the cover 29, this opening receiving the storage reser: voir 31 of the fiuid'systein.

Across theback of the frame a piece of webbing 32 is stretched, which webbing supports the group of back springs 33. These back springs are enclosed by a burlap casing 34, which is secured at its edges to the back rails 18 and 20 and the vertical bars 23. This casing is covered by stuffing 35 and the studing is coveredby'the back cover 36. The back cover 36 is secured at its lower end to the lower back rail .19 and extends over and is secured at its upper end to the rear side of the upper back rail 20. At its sides this back cover 36 is secured to the outer side of the vertical bars 23. as best shown in Figure 4.

The webbing 32 is covered by a piece of burlap 37, and over this burlap is arranged a sheet 38 of felted material, this felted material being covered by the back cover 36 which is extended over the rear side of the back and is secured at its lower end to the lower back rail 18.

Each of the arms, as best shown in Figures 3 and 4 is upholstered in the following manner:

On the upper side of the arm rails 21 is arranged a longitudinal row of springs 39 which are housed in a burlap casing 40. Between the arm rail 21 and the upholstering rail 22 a piece 41 of burlap is stretched and over this piece of burlap 11 and the burlap housin 40 for the springs is arranged a mass of stufiin 12, which ismolded to conform to the desired shape of the arms. The stuffing is covered by the arm cover 43 which is secured at its lower ends to the side rail 19 and extends completelyaround the arm. The stufiing 42 extends around the underside of the roll or bulge of the arm, and to prevent its inward displacement a piece of .burlap 44 is secured to the arm rail 21 and at its lower end is secured to the inner side of the cover 43. I

It will, therefore, be apparent that the above construction provides an upholstered chair which has an interior hollow compartment 15 in the back, an interior compartment 46 in each of the arms and the upholstering is arranged to provide the breaks 13 and 14 around the seat, which permits things to be inserted between the seat and the arms and thoback. thereby completely concealing the same within the breaks and 14. The reservoir 31 which is adapted to contain a supply of the moth exterminating'fiuid sufficient for a number of sprays of the piece of furniture is secured to the front side of the lower backrail 18. by-means ofa strap 47. This reservoir inc? udes a vertical cylindrical body which isclosed at its upper and lower ends by heads 18 and 19. In the upper head v4E8 is screwed a short sectionof pipe 4 91, in the upper end. of which is arranged a swivel elbow 50. Extending laterally from this swivel elbow 50 is a filling pipe 51having an elbow 52 at its outer end, which elbow opensupwardly.

The filling pipe 51 is arranged to swing rearwardlyinto the break H between the back 11 and the seat 10 andibe completely concealed within this break. When it is desired to either fill the reservoir 31 with the moth exterminating fluid or to create an air pressure in the upper part of the reservoir the person spraying the chair reaches in the break 14, pulls the filling pipe 51 out, and pours a suitable quantity of moth exterminating fluid into the reservoir through this filling pipe. She thereafter attaches a suitable air pump (not shown) to the filling elbow 52 and forces air into the upper end of the reservoir. Such a pump ma-yibe of a size which can be conveniently and readily inserted into the break 14 and be stored therein in a position in which it is completely concealed and does not in any way afiect the comfort of the chair.

' Ashort section of pipe 53 issecured on each side of thereservoir 31 at the lower end thereof and each connects with a vertical pipe 54: which extends up through an opening in the back upholstering rail 24, as best shown in Figure 1. At its upper end each of these vertical pipes 5 1 is connected-to a hoI-izontal. 1'ear pipe 55 which extends outwardly therefrom and is arranged in front of the vertical bars 28. Each of these pipes 55 have a T-coupling 56 to which is secured a vertical pipe 57 which extends upwardly between the vertical bar 23 and the corresponding back post16. The upper end of this vertical pipeisclosed by a cap 58. To the other end of each 'of the T-couplings'56 is secured a short section of pipe 59 which is connected by an elbow 60 with a longitudinal extending pipe 61, the outer end of which is capped. These pipes 61 are arranged within the interior compartment 46 of the arms and the pipes 55 are arranged in the interior compartment 45 of the back. Each of the pipes 6.1 and 55 are provided on their upper and lower sides with a series of ports 62, which series extend the entire length of these pipes and permit the fluid under pressure in these pipes to escape therefrom in fine streams which completely saturate the interior of the upholster ing of both the armsand the back.

In a similar manner the vertical pipes 57 are provided on their front and rear sides with a series of ports which spray the moth exterminating fluid into the break between the back and the arms, as best shown in Figure 4. I

It will, therefore, be apparent that when an air pressure is created in the upper part of the reservoir 31 the fluid is forced through the system of pipes just described and is sprayed into the interior of the arms and the back and is also sprayed in the break between the arms and the back. By this means the fluid is sprayed at the places where moths are lodge, particularly in the breaks between the different parts of the upholstering. Moreover after being sprayed the fumes of the exterminating fluid are retained within the upholstering for a very considerable length of time and only infrequent use ofthe device is therefore necessary to completely insure the extermination of moths from the piece of furniture.

In Figure 5 is shown a modification of the invention, shown in Figures 1-4. In this modification a reservoir and piping system is provided which is made and sold as a unit and i's-adapted to be inserted in upholstered.

most likely to furniture which-is alreadyvfabricatedor in actualuse. In this construction the reservoir 31 is arranged horizontally and is of comparatively small diameter therebyv permitting it to be readily inserted int-he break 14 between the back and the seat of the chair. The filling pipe 51 is similarly c011- nected by an :elbow swivel with a short pipe section l9 communicating with the upper endof the reservoir 31 as in the preferred construction andswings in and out of the break ll as described.

The pipes each connect with the end of the reservoir 31 through inclined pipes 54 arranged at the lower end thereof and at its outer end each pipe 55 is connected by. an elbow with the longitudinal pipe 61 which ex.-

tends along the corresponding arm. By this means a reservoir with a U-shaped system of piping is provided and the complete unit can be inserted into the breaks 13 and 14 between the seat 10 and theback 11 and arms 12. The pipes 55 and 61 in this construction are provided with a series of ports which spray the respective break. The operation of this form of-the invention. issimilar to the operation moth exterminating fluid into the or system shown in the preferred form. In

7 order to permit of adapting the pipe system to d'iiferent sizes and types of furniture a coupling is'provided in the pipe 55. By

this means if this form the invention is being app-lied to davenports, one section of. the pipe 55 can be cut tothe desired length and eeupled'to the other section by means of the I coupling 80. a

If it is desired to providemeans whereby the weight of a person. sitting down in the chair will operate to. cause a small amount of moth exterminating fluid to be sprayed into the upholstering, a small .air pump 70 may be housed within the seat 10, the casing of this pump being secured in anysuitable manner to the webbing-25 and the piston rod thereof'may be secured to the underside of a burlap casing 27. The outlet 71 for this pump may be connected with the reservoir 31 byme-ans of a flexible conduit 72'or in any other suitable manner. By this means whenever a person sits down in the chair he moves the piston rod of the pump 7 O downwardly and creates a pressure in the upper part of the'reservoir 31 which operates to force a small quantity of the moth exterminating fluid through the piping system and into the upholstering.

This pump is more particularly adapted for the form of the invention shown in Fig ures ll inasmuch as it is necessary to build it into the chair or piece of furniture while it is being upholstered. It is obvious that while the present invention has been shown and described with reference to an overstuffed. arm chair that it .is equally applica- I variously organized to suit different requirements without departing from the scope of the invention, as set forth in the appended claims.

As a whole this invention provides a very simple and inexpensive system of pipes whereby moth exterminating fluid can be effectively sprayed into the interior of the upholstering and thereby permeate the entire piece of furniture. It'is also convenient to use and when not in use is completely concealed in the upholstering and does not in any way interfere with the comfort of the piece of furniture.
