The instant invention relates to improved machines of the type employed for pneumatically conveying insulating materials and the like.
At the present .time a wellknown and efficient method of insulating wall spaces, such as the wall spaces defined by the studding, inner lathing and outer sheathing of frame buildings, resides in filling such spaces with insulating 6 Claims. (Cl. 302-50) material conveyed in an air stream. A preferred material for this purpose comprises mineral wool in the form of relatively small aggregates, known commercially as modulated or granulated mineral wool. It will be understood that the term mineral wool is used herein in a generic senseto include fibers or fibrous material formed of rock,
slag, glass, mixtures thereof and other similar raw materials. The filling of the wall spaces is accomplished with a machine comprising a blower, a, discharge line from the blower and into which the bulk insulating material is fed from a suitable hopper, and a, hose extending from the discharge line and having a nozzle to be inserted in openings formed in the building Wall leading into the stud spaces.
The instant invention is concerned with, and has for its principal object, the provision of an improved blowing machine for use in operations of the kind referred'to above. More particu- 1arly, an object of the invention is the provision of a blowing machine which achieves, as com- Fig. 4 is an elevational view of the right hand end of the machine as shown in Figs. 1 and 2;
Fig. 5 is a sectional view taken on the line 5-5 of Fig. 2;
Fig. 6 is an enlarged detail view of a portion of the apparatus; and,
Fig. '7 is a further enlarged detail view of one feature of the apparatus shown in Fig. 6.
Referring now to the drawings, there is shown a blowing machine, indicated generally at [0, adapted particularly for use in the installation of insulating filling in building walls and other confined spaces. The preferred insulating material is modulated mineral wool and the like, although it will be understood that the use of the machine is not limited to any particular type of filling.
Machine Ill comprises a frame l2 suitably made up of channel members, as shown, joined together to provide a platform or base for the support of the several elements of the apparatus. Supported on the frame is a hopper l4 adapted to receive the material to be blown. Hopper 14 (see particularly Figs. 1, 2 and 5) has a substantially vertical side wall l6 and an inclined side wall 18, the two being connected by a curved bottom wall 20. Walls l6, l8 and may be separate metal sheets jpncd together by welding or the like, or a single, integral sheet bent into the desired shape may be used. The hopper has end walls 22 and 24 welded or otherwise secured to the other walls.
ing means for controlling the movement, of the insulating material and preventing its backward travel under the pressure of the air blast set up by the blower.
A further object of the invention is the provision of a blowing machine having an insula- Fig. 1 is a plan view of amachine embodying the instant invention;
Fig. 2 is a side elevational view partially in section of the machine of Fig; 1;
Fig. 3 is an elevational view of the left hand end of the machine as shown in Figs. 1 and 2.;
The blower is driven by any suitable prime mover which may be a gasoline motor M indicated'in dotted lines in Fig. 1 and separately mounted on the truck bed or other foundation, or which may be the truck motor itself. The drive includes a pulley All forming part of a clutch element mounted on a shaft lid supported in bearings 35. t, 52, is provided between the shaft 44 and the driven shaft 54 of the blower. The clutch, which may be of any conventional or other type, is manipulated by lever 56 to engage or disengage shaft it from driven relationship with pulley 4i] whereby the blower may be started or stopped as desired.
Mounted for rotation in the bottom of the hopper and projecting into the tubular passageway through mouth 26 is a screw conveyor 58. The screw conveyor includes a spiral flight which fits tube 2i; with small clearance and extends to, or substantially to, the Y-connection between tube 29 and conduit 32 (see Figs. 1 and 2). The conveyor is carried on and fixed to a shaft (ill to rotate therewith, the shaft being supported in bearings 52 and 64 at opposite ends of the ma-- chine. The shaft projects beyond bearing 54, the projecting end carrying a pulley S6 connected with a pulley 63 keyed to the output shaft of a change-speed gear box 70 by belt 12. The change-speed gears in box 78 are driven from shaft as through the medium of bevel reduction gears'in gear box ill directly connected to shaft is and connected to the change-speed device through jack shaft 16. Shifting of the gears in the change-speed device is effected by gear shift lever 11.
Shaft t l carries a number of breaker fingers extending angularly and either in line or in staggered relationship from the shaft. The fin-- gers are located adjacent the end of the flight of the conveyor and partially in the Yconnection 539.
An end of shaft Bil opposite pulley 56 projects beyond bearing 62 and carries a pulley 89 operatively connected by a belt 32 with a pulley as keyed to a breaker bar 85 carried in bearings 38 in the end walls of the hopper. The hopper end wall is inwardly recessed to receive bearing 62 and the drive elements for shaft se. The recess may be closed by cover plate 89 (omitted in Fig;
3). Shaft 85 carries a plurality of breaker arms alternate arms lying in common planes at st. tantially right angles to the common plane of the intermediate arms. Alternate arms preferably extend at an acute angle to the shaft 85 which lies above, but laterally offset with respect to, screw conveyor 58, as illustrated in Figs. 1 and 3.
In the operation of the apparatus described above, the insulating material, such as nodulated-mineral Wool, isxdischarg'ed into hopper M A pulley and belt connection 48,.
suitably to substantially fill the same. Motor M, orthe truck motoras the case may be, is operated and the clutch is engaged by manipulation of lever 56 to cause rotation of shaft 44 and, hence, operation of the blower. Gear shift lever ll is shifted to obtain the gear ratio required to cause rotation of shaft 60 and, hence, rotation of the screw conveyor at the selected R. P. M. Due. to the drive connection between shaft 60 and breaker barBB, the latter is rotated in the same direction as the screw conveyor. Rotation of shaft 86 causes breaker arms 90 to break up 'large clumpsor agglomerations of the insulating material-whereby the material is deposited in relatively loose, open, fibrous form at the bottom of the hopper. onto and adjacent conveyor 58. The materialis deposited bya combination of gravitational force and the action of the breaker bars into the screw conveyor through the relatively open space tothe left of the conveyor, as viewed in Fig. :5. The conveyor feeds-the material forwardly through the funnel mouth formed by baffle 21 and into the tubular passageway. The funnel mouth overcomes the tendency of the insulating material to move out of the conveyor as it reaches the entrance to the passageway. The material is deposited by'the screw conveyor at the Y-connection in the path of the airstream created by the operation of the blower. The material is picked up by the airstream and carried thereby through hose 38 to the place of discharge.
The numbenl character and. arrangement of prongs 92 may be varied to secure the desired density conditions of the insulating material. For example, for higher densities, a greater number and in a wider pattern are employed with increased resistance to movement of the material along the conveyor flight. As illustrated in Fig. 6, preferably the prongs or protuberances are concentrated at one portion of the flight and are of relatively small number to avoid packing of the material to an undesirable extent. However, as substantial packing is required, breaker fingers Iii are provided to open up the material and separate it into relatively loose form as it enters the airstream whereby it may be distributed in the wall or other place to be insulated.
The particular construction and design of the hopper, cooperating screw conveyor, and breaker bar, including the positioning of the screw conveyor at one side of the hopper to leave an open space, and the positioning of the breaker bar to force insulating material into the screw conveyor through such open space, prevents brid ing of the material and insures that the conveyor will continuously pick up a full load.
The Y-connection between the tubular passageway and the air conduit permits the insulating material to be picked up by the airstream in substantial continuation of the forward movement imparted to it by the screw conveyor and, hence, promotes free flow of the same into and with the airstream. The breaker fingers at the end of the conveyor loosen up the material packed by the conveying operation and return it to an open state. All of the features discussed above cooperate to provide continuous and uniform flow of the insulating material at a predetermined rate without the danger of blow backs. The operation is entirely automatic, requiring merely the dumping of the insulating material into the hopper. The insulating material does not have to be pushed into the feeder by hand as is customary in many machines. The speed of rotation of the conveyor relatively to the rate of air delivery by the blower may be controlled through change-speed gear box 10.
Having thus described our invention in rather full detail it will be understood that these details need not be strictly adhered to but that various changes and modifications may suggest themselves to one skilled in the art, all falling within the scope of the invention as defined by the subjoined claims.
