@animi 5t 'am @met PATRIACK CLARK, OF vRAVIrIWAY...NEW, JER-ilil Lam Patent 1ra-85,213, am; mamar 22, 186s.
rmRovmmNTrN PAN-snowman.
The Schedule referred to in these Letten Pntent fand making part of the same.
To all whom t may conce/rn f the shell together;
Second, in providing an improved means to arrest the rotary motion of th'e air, thereby causing it to pass from one fan-chamberto the next, without material 'v lossof pressure; and,
Thirdly, in providing the shaft "and hearings with a new -and 'improved means of adjustment, by means of which the shaft of the fan may b e adjusted 'longitnf dinally alter the machine' is set up.
To enable others skilled in the art of making and using fan-blowers to make and use my improved' fanblower, I will describe the construction and operation of my improvements in the following specification and the accompanying drawings, which form a part Aof this specification.
In the accompanying drawings- Figure 1 is a perspective view;
Figure 2, a vertical longitudinal section;
Figure 8, a' `vertical cross-section through the line A B, and parts to the right of said line, viewed from the left-hand end in the line of the shaft; and
Figure 4 is an enlarged vertical cross-section of the same parts, made large to show the details of animprovement-connected with the bearings. v v
lhesame letters refer ,to the same parts in` all the figures.
In the accompanying drawings- C, fig. 2, is the shalt, (hiven by the pulley D, and carrying three fans E E, 85e., each in a separate compartment, but havingcolnmunication with each other through the spaces and openings in the direction marked by the arrows.
F F are the diaphragms o1; partitions, .which form one side of 'the space in which the fan-wheels revolve.
These partitions do not extend entirely across the diameter of the shell, but have an annular opening, H, iig. 4, through which the air escapes to the back of the diaphragm or partition F, and down between itand the outside of the nextian-chamber, to the centre of the next fan, as shown by the arrows in figs. 2, 3, and 4. These partitions are conveniently made of ,sheetiron, and may be made to fit the shaft by means of' ai leather packing. As the air leaves the fan-wheel, it has. a motion in common with it, which rotary motion must be arrested, orl otherwise the air would not return toward the centre of the next fanchamber;
To arrest this rotary motion of the air, the stops or deflectors GTG, figs. 2, 3, and 4, arelntrodueed between.
" the back f the partition F, figs. 2, 3, 'and`4, and the side of the next fan-chamber. They might he extended:
into the fan-chamber itself', at its outer periphery, but
by so doing the fan would require a very considerable additional amount of power toL drive it. These deflect- 01s or stops are shown in igs; l2 and 4, in vertical longifndin'al setion, and in fig. 3, in vertical cross-section.
M M, figs. 2 and 4, are the journals of the shaft,
revolving in bearingsI I, figs. 2 vand 4. These bear? ings are secured in their/place as follows: l
The hubs Q0, figs. 2, 3, and 4, are supported by the arms J J, figs. 3 and 4, which arms4 arev cast fast to those sections of the shell markedPand U. The hole through the centre of the hubl is so formed as to fit half of the exteriorof'a plano-convex ring.l
The hole in the hentre of the loose part of thehub, marked'K, figs. 3 and 4, has the same form, but-on the reversesidaso that, when. they areA brought together;
theyform a segment of a spherical cavity.-
Into this spherical cavity is fitted the-plano-convex ring L, Ifigs. 2 and 4, bored out to fit the exterior of the journal-box l. ',This planolconvex vring is l'out in the line of its axis, i. c., in the line of the shaft' of the blwer.- r l y These parts being put together 'as'deseribech it is plain that the nantis ofthejournal-box will be free to go into line with the axis of n the journal, by reason of' its partial revolution about the central point of the .spherical belt, and that the journal-box and shaft may he adjusted longitudinally, byreason `ot' the journalbox being free' to slide through the spherical heit in the lineof'the shaft.
` When Ithe adj ustments are thus made, `the 'journalbox I may be fastened by tightening the screws N N.
The general sli'ell, enclosing the fans and other ar rangements, is constructed most conveniently of castiron. It consists of four pieces, viz, P, R, S, andU, but
-S and P are so near alike that they may be said to be identical; They are shown in. perspective in fig. l, and
in section in iig. 2.
. P, 'fig-2, which constitutes one end of the shell, is of adishingibrn1,l1aving a depth sulicient to allow the ian-wheel to revolve freely within it, and a diameter at- -least one-fourth greater than the fan-Wheel, the other parts of the shell having an equal diameter.
1t forms a junction with R, the second plate in the.
series, at X, tigs. 2 and 4, by means of a flange. Plate it is also' of -a dishing form, but not so deep :is 1),.but
sufficiently deep to allow of a free ,passage of the air, between the partition F and plate R, to the central opening' of the next fan-chamber.
To this plate, on the left.side, are attached the stops Y or deiectors G G, gs. 2, 3, and 4, thesheet-iron partition-F resting against them, and secured by the screws or rivets Y Y. A i
, On the right 'side of plate R, at Z, iig. 2, is a pro jectingbeall, on which fits the dishing plate or section S, which,- with that pa-it of plait-e R against which it` rests, f'oi'xnsnJ `section siinilznto P, making a. second thin l chamber, mdso on for any hunlbelrof fans required, the Whole :shell being mode up of repetitions of lt and S based on P, the whole series heiligen-,cured togetliiel1 bythe bolts T; '4 Now, I do not elnini oonsti'ueting a, fan-blower, hoviugtwo or more fans on the .Sallie shalft revolving` in separate eompz'ti'tmentgfor Suche machine 'Wa-s -petented by'lznnes A.
