"1'0 a 'L whom it may concern:
in county of Hartford and Stateor Connecticut, have invented a new and HI'OEOVQQ Blower for Musical l-nst urollowing is a specifical: v invention relates to the class of devices or producing a current of air, the improved evice ing the subject-matter of this apit)! using more especially applicable tor creating a current for use in musical instruments, although it may he hund applica ole is; use in connection with other devices and is therefore not limited especially to use in connection with a musical instrument.
object of my invention is to provide a blower that shall he freefiom the objections present in prior devices resulting from the noise created in the operation of the blower; and a further object is to provide a device which may he set up or installed with cornparative readiness and ease; and a further object of the invention is to provide a device the advantages hereinhefore noted and in which access to the motor may be these objects may be attained is illustrated in the accompanying drawings, in which-i- Figure l is a view in central vertical longitudinal section oi a blower embodying my invention. Fig. 2 is a view in crosswise section through the device shown in Fig. 1 on a plane passing through the deliverypipe and looking toward the right. ig. 3 is a view in crosswise section through the device shown in Fig. l on a plane passing through the structure oetween the dividingwallsand a fan-disk, looking toward the left, and'with the upper part of the fan-disk broken away. Fig. 4 is a detail view showing the bearing for one end of the shaft.
In the accompanying drawin s the numeral 1 denotes an outer case, an '2 an inner case. These casings are preferably formed of sheet metal and are supported by rings 3, which may be formed integral with either of the casings or secured thereto in any convenlent manner.
in constructing casings for blowers for musi'cal instruments prior to my invention it has been comm.
on practice to d de the casing longitudii Ly; an objection is present in such construction from the that the current oi r generated by the fans and 110wing circur rentially around he casing and across e seam formed hy the oint create considerable noise. It is desir in devices s that noise shall e prevented. nd by repeated cuts that v e casing is ivided circumrerentially insteae oi. longitudinally that this noise is prevened. therefore form the casing in ded circumferentially, as shown in Fig".- l or the drawings, and interfaces a ens er sections sound-insulating material a between the outer and imer casings. Heads 5 5'5 are provided at each end of the casing, these heads being secured'together and to the casing and the sections of the casino being secured together, as by means of rods 7 passing through the heads and along the outer surface of the casing l and secured, as by means of thumhscrews 8, fixed to the screw-threaded ends of Dowel-pins 9 are secured to the the rods. rings 3 for the purpose of holding them in alinement. The head 5 is provided with a cover 18, hinged at 11 to the support 12 and secured, as by a thumb-screw 13. The head 6 is provided with a cross-bar is, forming a bearin for one end of the shaft 15, an opening 16 cing formed through the head for the admission of air. Supports 17 are provided for sustaining the blower as a whole.
A main'division-wall 18 extends across the casing, dividing the motor-chamber 1.9 from the aircompartments 20. This main division-wall has an opening 21, closed by a cap 22. This map is loosely supported on the shaft and has a lining 28 of felt on that face next to the wall 18. ported and is held in place by the air-pressure within the air-chamber. Thus it forms what might well be termed a floating bushing covering the opening 21 between the motor-chamber 19 and air-compartments 20, always adjusting itself with the shaft without liability of cramping or binding.
A motor 24 is located in the motor-chamber l9 and is connected with the shaft 15 by .lt is loosely sup' structing the universal hearing as shown 111- 'Fig. 1 of the drawings it will be seen that the a universal joint 25. This shaftis supported at one end inthe bar 14 in a universal bearing 26.
In setting up the casing it often happensshaft will readily accommodate itself'to the position of the motor and that the latter may be'moved to a considerable extent-without interfering with the properoperation ofthe shaft, and hence when the blower is once setup itneed not-be taken-down by reasonof the motorhaving been moved from itsproper' position with the shaft in alinement;
Partitions 27 divide the air-chamber up into compartments 20, in which are located fan-disks 28,- to which are secured fans orvanes 29. The edges of-the fans revolve in close-proximity to the partitions 27, the air passing through the openings 30 in these partitlons.
The air enters through the opening in the cover 6 at each side of the cross-bar 14 and passes into each of the succeeding chambers, the ressure being ralsed in each of the succee ing chambers. The shields 31 revent'a circular motion of-th'e air in all 0 the aircompartments except the innermost, and in this chamber circular motion is allowed, and owing to the location of-the outlet-pipe the air freely passes out of said pipe to a suitable reservoir or pressure chamber or direct to the musical instrument, as the case may be.
The air in-each of the succeeding compartments from the inlet 16 is raised-in pressure, being higher than in the next preceding compartment. l have shown herein the outlet 32, extending from the innermost compartment; but it will be obvious that outlets may be made from any of the com artments and airsupplied'inthis way under iiferent ressures, as may be required, from the same lower.-
