@glatten tstes atmt @ffice AMOS WESTCOTT, OF SYRACUSE, NEW YO RK. Letters Patent No. 63,343, dated Inarch 25, 1867; anteclatccl March l5, 1867.
IMPROVEMENT IN FAN-WHEEL BLOWER.
'IO ALL WHM IT MAY CONCERN:
Be it known that I, AMOS WESTCOTT, of the city of Syracuse, of the county of Onondaga, in the State of New York, have invented a new and useful Improveincntiu FamWheel Blowers; and I do hereby declare the following to be a true and exact description of thc same, reference being had to the accompanying drawings and to the letters of reference marked thereon. n
To enable others skilledin the art to make and use my invention, Iwillproceed to describe its construction and operation. A i
In the accompanying drawings, in Figure I, the full lines represent this Y blower, with its dierent parts attached, in perspective, while the dotted lines represent a. front View of the several parts indicated. A, iig. 1., represents the front surface of the case or box enclosing the fan-wheel B, the bottoms or what would correspond to the cover of the box, which is here represented as inverted, or with its cover resting upon the plain surface` I, 2, 3, 4. 'C C C C are orices cut throughthe front for the ingress of air; e and g, studs made fast te the body of thc case, passing by the cover B, and turned at right angles with the side of the box. In Eg. l, and
z, are screws, under the heads of which that portion of the studs and g g passes which projects from the circlel of the box. Attached to the cover at a, iig-I, there is a spur, which passes above the horizontal portion or foot g g of the stud e, and outside that portion which is perpendicular. A similar spur is attached to its cover on the opposite side 'of thebox, passing over thestud g, and which is shown at the point h and i 71, Figure 2. In tig. l the circular dotted line c represents thefrictionroller attached to the shaft of the fan-wheel, against which the enlarged rim Z Z of the pinion-wheel k presses. In iig. 2, A', represents this blower (as laid upon the plain surface I, 2, 3, 4) with the front of the box removed.A a a a a the fans turned or twisted upon their shaft so as to propel the air directly towards. the point of egress or'orifce B. dd are the horizontal portions of the s-tud over which the heads of the screws g and g g act, to secure the box to the structure against which the blower is to be fastened. In tig. 2, B represents the open end of a tube made' fast to and passing through the cover, and which serves the double purpose of giving egress to the air, and for a centre upon which the case is turned to attach or detach the blower'to or from the mach-ine with which it.may be used. Figure 3 represents a transverse sectionof the blower as attachedv to a box, the end of which box is shown at A A. In this figure, B B represent the fans, the arrow g the direction of the air as it is forced out by the action of the fans B B. In iig. 3, C C represent the feet of the studs upon which the heads of the screws e al press to holdtheblower firmly in place.` This blower, which is designed to-be` used principally Where only a small-sited one is required, and where it is desirable to remove it and replace it easily, may be constructed of sheet iron, tin, sine, or other metals in the sheet form, and the box is made in everyrespect like any ordinary tin box, having a cover shut' ting over it,the diameter of which being three or four times its depth or thickness. After cutting holes,
`C C C C, tig. l, forthe ingress of air near its centre in the body of the box, and establishing opposite centres,
the one in the cover, as at c, fig. 3, and the other in the bottom of the box f, iig. 3, for the shaft of the fanA wheel, a tube is inserted into the cover,the end coming even with its inside surface and'near to its edge, and attached to it air-tight. In order to fasten securely the box and covervtog'ether, the studs c and g, fig. 1, or dd, iig. 2, are made fast to the sides of the main box. These studs, as they run towards the edge upon which the cover rests, are turned outwards, so as tofpass by the edge of the cover, so as to admit of its being put on and taken oi` without interfering with them. After theyy have been extended perpendicularly to the angle made by thecover and the'sidc of the box, they are turned outward at right angles, so that the spur a, viig. I, whichA is fastened to the cover of the box, passes over this projection, and holds the cover to `the box securely. When thus placed togetherand fastened as abn'e described, they will appear as in g. 2, at z and h z. These .studs are also employed in holding the box and cover to any machine upon which the blower is used. In tig. 3 this is clearly shown. When the blowen isA placed upon a plain surface, so that the centre of the box is at z', fig. 2, Athe studs n. an'd lc are cach free from any fastenings, but as it is moved about the centre or tube B, from c to Vd, the bifurcated foot d passes under and astride the thumb-screw y g and the foot n, under the screw-head g, so that by turning the thumb-screw e, g. 8, we are enabled to fasten the box securely in its place. The saine operation that thus enables us to fasten the boxv to any other structure, also holds more firmly the box and cover together.` As the friction-roller R, fig. S, moves with great velocity, and is hence liable to be worn away, it is desirable to have some easy mode of adjusting the blower so that the pressure will remain equal, whatever may be the size of this roller. This is done simply by turning buck the thumb-screw e, fig. 3, and carrying this wheel toward the friction rim of the driving-wheel Z Z, iig. l, and securing it by said screw at the desired position. In constructing my blower I make the 'orifice for the egress of air ou the side of the box, as indicated at B, iig. 2. By placing it at this point it serves as a centre, about which the box containing the fan-wheel may be turned to relieve it from the screws g and g g, fig.' 2, and also from the other parts, which would prevent it from coming oil' until it was so turned outward. Placing the tube in this position has not only this advantage,
` but also serves as an additional support to hold thc blower in place. When the hole is 'thus made on the side of the box, it greatly facilitates the egress of the :tir to have the fans so turned or twisted as to have them face it as nearly as possible. Hence each fan in my blower, instead of standing with v its face at right angles with the shaft about which it revolves, is so turned as to carry the air directly towards the outlet for the air B, fig. 2. Being aware that fanwheel blowers have been long used, I do not claim the box or case, nor the fans as ordinarily constructed; but what I do claim, and desire to secure by Letters Patent, is
claim a fan-wheel blower propelled by friction-wheels as shown, and enclosed within the parts Aj B, coustructed oud made adjustable substantially in the manner described.
