Hine, San Francisco, Calif... assignora to The Pacific Lumber Company, San Francisco, Calif., a corporation of Maine Application July 8, 1941, Serial No. 401,478 8 Claims. (01. 302-37) jecting into the free portion of the bore of the This invention relates to apparatus for pneumatically forcing fibrous insulating materials through a pipe for placing the materialsin wall spaces for the thermal insulation of the walls, and for other uses.
The objects of the invention are to provide improved apparatus which will more expeditiously handle chunks of baled shredded bark fiber, and efiectlvely deliver the fiber in uniformly loosened up condition. Specific advantages and features of the invention will appear in the following description and accompanying drawings,
In the drawings- Fig. l is a perspective view of our improved pneumatic fiber placing machine showing its feed hopper and outlet or placing pipe, and driving engine.
Fig. 2 is an enlarged cross section of the centrifugal ejector, taken from the line 2-2 of Fig. 1.
Fig. 3 is an enlarged longitudinal central vertical cross section of Fig. 1 with the driving engine omitted.
h'ub thus provided is a continuing shaft l4 which extends horizontally through an elongated cylindrical shell or casing l5, and is rotatably supportedat its outer end by a bearing I6 secured to a plate ll closing the end of the cylinder..
Shaft N is provided at its inner end with a transversely extending driving pin [8 projecting at both ends into slots l9 cut in the end of hub 9--the arrangement being to permit easy connection and separation of shaft i l from hub 9, as
well as to obviate the otherwise necessity of ac- "curately aligning the shafts. The adjacent side Fig. 4 is a cross section of the picking cylinder taken from the line 4-4 of Fig. 3.
Before describing the drawings in detail it may be said that the machine as shown in Fig. 1 comprises a base or bed plate I upon which is mount= ed an internal combustion engine 2 (or other prime mover) the shaft of which directly oper-' ates devices for thoroughly opening up andloosening compact masses of shredded bark fed into the hopper 3 and ejecting the fluffed up mass in an air stream forced out of pipe 4 by means of a centrifugal blower 5.
It is of course recognized that power blowers through :piping, including shredded barkfiber, and such apparatus has been heretofore used 'by applicants assignees, but the condition of the finally placed fiber was not entirely satisfactory as it was not uniformly or evenly separated or flufied up, but on the contrary carried in it conhave been usedfor ejecting all sorts of materials siderable fiber which was lumpy and unsuitable for best thermal results, whereas with the im-' proved apparatus of the present invention the defects mentioned are entirely overcome.
In further detail the projecting engine crank shaft isdesignated s and it extends through an opening 1 in one side wall 8 of the blower casing 5 and directly supports the hub 9 of the blower wheel I within the casing. The shaft 6 does not extend entirely through hub-l but terminates at dotted line H at a point spaced inwardly -from the remote end of the hub and is secured to the hub as by a key 12 and set screw l3, while proedge picker blades 2| alternately arranged at right angles as indicated, and projecting inwardly from the-cylindrical casing I5 is a plurality of pointed pins 22 or sharpened screws. These pins are arranged in several rows along the upper and both sides of the casing only as the lower half of the casing is left clear for the easy passage of material to the blower housing, and through the center of one side of which blower housing the end of the cylindrical casing l5 opens and connects thereto by a flange joint 23 re.- movably secured-in place as by screws 24. Pointed pins 22 are threaded so that their projection into the casing l5 may be adjusted. The taper of the picker blades avoids snarling up of the fiber on the picker shaft.
Adjacent the outer end of easing i5 is a vertically extending chute 25 formed with a flaring hopper 3 on its upper end, while at the extreme outer end of cylindrical casing i5 is one or more air inlet openings 28 which may be more or less closed off by an adjustable shutter 21. It should be noticed that these air in-' the blower wheel II, and that the picker blades 2| are about a quarter the diameter of the blower wheel, as this keeps down the peripheral speed so the picker will pick apart the lumps of fiber and not destructlvely disintegrate and destroy it.
The form redwood bark fiber, and consists of a E'solid of the blower wheel I has been developed after considerable experiment to meet the special requirements of handling shredded .gular plates 29 welded to hub '9. Vanes 28 are broadest at their outer .ends and tapered toward the hub to fit the secured to the hub 9. I
Disk I is conically dished forwardly over I thegreater part of its diameter to about half the breadth of'th'e vanes 28 where it meets the hub 9 as indicated at I0, and is rigidly braced in this dished position as by a plurality of an to the disk as well as dished form of the disk It and are also similarly tapered on their forward edges to about half this amount, thus providing a space between the forward edges of the varies and the wall 8 of the blower housing which becomes narrower toward the ends of the vanes. The outer ends 28' of the vanes are curved backward or in a direction opposite the direction of rotation of the impeller wheel indicated by the arrow. The outer end of the casing I is secured to and supported in horizontal extension on a bracket 30 and the engine 2 is similarly supported on a pedestal 3 the base plateor frame I, so as to make a rigid portable assemblage, the moving about of which is facilitated by provision of a rail handle 32.
The use of a gasoline engine as the prime mover is preferable to an electric motor for the reason that in orderto drive a blower wheel of about two feet in 'diameter at the speed desired, about five horsepower is required, and normally the power sockets available in home districts where these machines are frequently I, all in turn secured to are similarly of fiber and production of objectionable dust than prior machines used for this p p se.
Having thus described our improved pneumatic' bark fiber claim is:
1'. A pneumatic baled insulating fiber comprising a' rotary blower having a. housing with a multivane impeller wheel therein, apower shaft extending through one side of the housing supporting the impeller. a cylindrical casing secured at one end toand extending laterally from the opposite side of said housing and open at said end to the impeller space, a' picker shaft extending through said cylindrical casing connected at its inner end to said power shaft and supported at its outer end by a bearing carried by said casing, cooperating picker elements projecting from said picker shaft and said casing," means closing the outer end of said casing, a feed chute extending upwardly from said casing, .means for admitting air to the outer end of said casing, and means-for adjusting the projection of the picker elements from said casing, the bottom of said casing being free from picker elements.

The engine also permits the machine to be used on new work before the electric installations have been made, and is also less expensive to run.
