BELLOWS.
SPECIFICATION forming part of Letters Patent No. 334,934, dated January 26, 1886. Application filed July 9,1885. Serial No. 171,152. (M0(lcl.)
To all whom it may concern: Be it known that I, GEORGE l. CAMPBELL, of San Francisco, in the county of San Francisco and State of California, have invented a new and Improved Bellows, of which the following is a full, clear, and exact description. My invention relates to bellows adapted particularly for discharging sulphur, parisgreen, or insect-powder onto trees or plants or about furniture, and also for blowing the loose sand from molds used in casting metals, and for distributing facings over the faces of the molds, the bellows being simple, inexpensive, and durable, and readily adjustable and gontrollable for the various uses above speci- The invention consists in certain novel features of construction and combinations of parts of the bellows, all as hereinafter fully described and claimed.
Reference is to be had to the accompanying drawings, formingpart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a longitudinal sectional elevation of my improved bellows. Fig. 2 is a plan view thereof, with the cap or cover of the powder-box removed. Fig. 3 is an enlarged sectional side elevation of the check-valve and air-tube of the powder-box, and Fig. 4 is an underside view of part of the top board of the bellows and the air cut-off valve; and Fig. 4 shows a plain slide-valve;
The letter A indicates the bottom or baseboard of the bellows, which has fixed to its forward end the block B, through. which is formed the air-outlet passage b. To the block B is hinged, by a flexible strip, 0, the top board, 0, to the edges of which and the base-board A is attached the flexible side wall, D, of the air-reservoir E of the bellows.
Inside the baseboard A is hinged the flapvalve (1, over an opening, a, through which the air enters the reservoir E, as the handles F F of the bellows are separated, the air being forced through the passage b and metallic nosepiece G, at the forward end of the bellows when the handles are brought toward each other.
The letter H indicates a box or chamber, which is secured to the board 0, and is of a size suitable for holding powdered sulphur, iaris-green, foundry-fitcings or other pulverized substance it is desired to scatter or dis tribute by the force of the volume of air discharged from the bellows-reservoir E at the nose G, the box H being connected with the nose by a flexible tube, I, fitted at one end to a nozzle, 7, of the box and at the other end to a bent tube, which opens into the nose G, as clearly shown in Fig. 1. A perforated or wire-gauze partition or plate, J, is fitted at the inner end of the box-nozzle h, to prevent choking up of the powder-passages between the box H and nose G by lumps or foreign substances which may by chance be filled into the box with the fine powder through an opening bordered by the screw-neck K, onto which a screw cap or cover, L, is placed to close the box when filled.
To admit the air from the bellows-reservoir E to the powder-box H, I employ a checkvalve comprising a tube, M, which is open at both ends, and has side openings or air-passages, m, which stand a little above the bottom of the box H, the tube M preferably be ing fitted at one end into a hole made through the board 0 of the bellows, as shown.
Around the tube M is fitted loosely an outer tube, N, which has a cap-plate, 0, supported at its top by short connecting strips or bars 12, so as to leave an air-passage, 0, between the inner face of the imperforate cap-plate 0 and the top of tube N. A spring, it held preferably to the cap-plate 0, acts between said plate and the applied cover L to force the tube N down to the bottom of the box H, and also force the capplate 0 down on the top of the tube M, so as to prevent passage of the powder from box Hinto the bellowsreservoir E. Onto the outer end or nose, G, is fitted a spout or nozzle, R, which, preferably, has a rose-head, 1", through which box H is discharged.
At S is shown a flap-valve fitted over the airpassage 1), to prevent the powder from being drawn back into bellous-reservoir1G from the noseG as the reservoir is filled with air.
As thus far described, the bellows is complete as a powder-distributor or insecticide, and its operation is as follows: The powder having been placed in the box H, and the the powder from M T, at the inner i cover L put on, as the handles F are operated to force the air from the passage 7), and through the nose G, some of the air will pass into the tube M, and will lift the cap 0 and tube N against the tension of the spring P, so as to allow the air to enter the box II through the lower passages, m, in tube M,and through the upper passage, 0, thus admitting the air at two levels or places next opposite faces of the box H, and insuring thorough agitation of the powder in the box, and a more effective discharge of the powder therefrom through the tribes I and giuto the nose G, where the powder is met or overtaken by the main air-blast through the passage 1), and ejected thereby forcibly from the nozzle It; or it may be directly from the nose G when nozzle It is not used.
When the bellows is intended more particularly for use in distributing foundry facings upon molds for castings, I will apply a valve, 'ace of the board 0, or so it may be operated to close the air-passage M, when the l'acings, which are placed in box II, are not to be blown upon the molds-as, for instance, when the bellows is to be used for blowing. the loose sand from the molds preparatory to diseharg'ingthe farings upon them.
The valve T may be applied in various ways to effect its purpose. I show it held by a screw, it, which passes through an outer supporting washer, t, and a slot, t", of the valve, and I show the back end of the valve connected to one arm, a. of a ciauk lever, U, which is pivoted in the board 0, and has an upper arm, a, above the board, which arm a may be turned to throw the valve T over and close the passage M, when the loose sand is to be blown from the molds, and to open the passage hit more or less when the facings are to be discharged from the box upon the molds.
The valve T may be used to regulate the blast through the box II when discharging any pow dered substance.
The powder-box ll may be attached to the base-board A, instead of to thehin'ged board, and in that case the box may be connected with the nose G by aflexible or rigid tube, as will readilybe understood.
I show the nozzle It 1- made in a form allowiug it to beplaced in the powder-box II when out of use; but the nozzle may have any desired form for any special purpose.
If desired, the spring I may be substituted by a coiled spring, I which is drawn open and attached at opposite ends to the lower end of the tube N and the bottom of the powderbox, as shown in dotted lines in Fig. 3; and
the valve controlling the air -'communieation between the reservoir E and powder box H may be a plain slide-valve, as at T in Fig. 4, with an end part projecting outside the reservoir, under the upper handle F, by which it may be pushed in or drawn out to cover the passage M or uncover it more or less as required.
Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A bellows comprising a collapsible airreservoir, a powder-box held thereto and communicating therewith, a. passage from the powder-box to the air-discharge end or nose of the bellows, a eli it-valve controlling the direct-air passage from the reservoir to the pewder-box, and a spring acting normallyto close said. valve, substantially as herein set forth.
2. The con'ibination, in a bellows, of the collapsible air'reservoir, outlet 1), powder-box H, a check-valve fitted thereto and comprising a tube, M, apertured at m, a tubular cap, and a, spring, I, and a passage from boxH to outlet I) or its nose G, substantially as herein set forth.
8. The combination, in a bellows, of the collapsible airreservoir, outlet 12, powder-box H, a check-valve fitted thereto, and comprising a tube, M,- open at both ends and apertured at m, a tubular cap, N 0, provided with passage 0 under plate 0, and a spring, P, and a passage from box H to the outlet passage G, substantially as herein set forth.
'1. The combination, in a bellows, of the collapsible air-reservoir, outlet b, powder-box H, check-valve M N O P, a. flexible tube, I, connecting box H with the nose G or a tubular offshoot ther from, a check-valve, S, and a valve, T, substantially as herein set forth.
5. A bellows comprising a collapsible airrescrvoir, a powder-box held thereto and communicating therewith, a passage from the powder-box to the air-d'scharge end or nose of the bellows, and a valve, as at T, substau tially as herein set forth.
6. The combination. in a bellows, with the collapsible air-reservoir, powder-box H, and a passage from said box to the air discharge end or nose of the bellows, of a valve, T, slotted at t and pivoted at t, and a double-armed erank-1evcr U a a, substantially as herein set forth.
