ROBERT BURNS, OF NEW YORK, N. Y,

FAN-BLOWER.

SPECIFICATION formingpart of Letters Patent No. 655,602, dated August 7, 1900.

pn cation flld September 21,1599. Serial No. 731,215. (No model.)

To all whom it may concern.-

Be it known that I, ROBERT BURNS, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented new and useful Improvements in Fans, of which the following is a specification.

This invention relates to fans or blowers, and has for its object to provide novel, simple, efficient, and economical means for reversing the fan-blades and fan-casing and converting the fan or blower from a right to a left hand machine, and conversely, and to adjust the casing so that its discharge-mouth may be set in different positions to suit the conditions required. This object is accomplished in the manner and by the means hereinafter described and claimed, reference being made to the accompanying drawings, in which Figure 1 is a side elevation of the fan. Fig. 2 is a face view of Fig. 1, partly in section. Fig. 3 is a detail sectional view of a fastening.

In the drawings is shown a base or support 1, forming the bearing for a shaft 2, which can be driven by pulley 3 to rotate the fan, comprising the hub part 4:, with arms 5 and blades 6. Cast with or secured to the base or casting 1 is a perpendicular pillar-plate 1, made of circular or disk shape and stiffened or A casing 8 is shown as having oppositely-located circular openings, the edges of which are indicated at 9 and 9. Each opening is made to fit or correspond This casing has also a tangential discharge month or passage 10, and about the edges 9 and 9 are applied clamping clip-plates 11, held by bolts 14, between lugs 12 on the casing of the fan-blades. When the edge 9 of one circular opening in the easingis seated about the circular or disk-shaped portion of the perpendicular pillar-plate the clip-plates ll engage and clamp the edges of the pillar-plate, and the fan-casing is thereby securely clamped and held in correct position. The machine is now a so-called right-hand machine or blower-what is to say, a person standing and facing the discharge mouth or passage 10 will have pulley 3 on his right hand, as seen in Fig 2.

Should the casing 8 be dismounted and its opening or edge 9 seated or applied to the pillar-plate 1, the machine is reversed or lefthanded, as a person standing and facing into the outlet will now have pulley 3 to the left of easing 8. The fan 4' 6 at the same time is dismounted and reversed and replaced on its shaft, so as to correspond to the reversed casing 8.

An inlet-collar 15 has a flange 16 corresponding to plate 1 or to the edges 9 and 9', so as to be applicable to either edge and to be held in place when fastened or engaged by the cor responding or contiguous set of lugs 11. The collar 15 when applied to case 8 forms an inlet and can serve for connecting to a so'called suction pipe. (Notshown.) The fanblades 6 when in motion force air through on tlet 10, the inflow occurring through collar 15. A current or blowing is thus effected.

Since the collar 15 can be applied to either edge 9 or 9 and the plate 1 can connect with either edge 9 or 9, the machine can be reversed or set to right or left hand, while but a single set of castings is required. It is also to be noted that the casing 8 can be set or rotated on 'the pillar-plate 1 to cause outlet 10 to point in various directions. In full lines, Fig. 1, is shown the outlet 10 pointing horizontally in a certain direction or giving a bottom horizontal discharge; but as shown by broken lines in said Fig. 1 the casing can be turned or set so that outlet 10 will point horizontally in the opposite direction for a top horizontal discharge or that the outlet points upward or downward for up or down discharge. The outlet can by revolving the casing 8 be made to discharge in any direction or angle in the plane of rotation of the fan 6. When the casing has been applied to the pillar-plate and turned or adjusted to the desired position, the clamping clip-plates are tightly fastened by the bolts 14 to rigidly clamp and hold the fan-casing.

It will be evident that by constructing the perpendicular pillar-plate with a circular or disk-shaped upper portion, in the manner described and shown, the pillar-plate remains fixed in one position under all circumstances and does not require to be shifted from one side to the other of the fan-casing 8 to con-' vert the fan from a right to a left hand fan, and, further, that the circularor disk shaped upper portion of the pillar-plate-never requires to be shifted and serves to close the opening in the side of the fan-casing applied to the pillar-plate, thus avoiding the attachment and detachment of a plate to close the opening in the supported side of the fan-casing, as heretofore. In my invention the fanshaft-su pporting frame 1, the fan-shaft 2, and the vertical pillar-plate 1 thereof are fixtures, or, rather, never require reversal; but the fan-blades and fan-casing are the reversible parts, which reversal can be conveniently and rapidly effected.

The openings 9 and 9' are practically of such size as to allow the casing 8 to be passed to and from its place over the fan 6 on shaft 2.

What I- claim as new, and desire to secure by Letters Patent, is

1. The combination of a supporting-frame having a-shaft-bearing therein and a rigid disk thereon, a shaft in said bearing, a reversible fan on said shaft, a reversible fancasing having a discharge-mouth, and having circular openings in its opposite sides, either of which fits, is rotatable upon, and is closed by said disk, radially-arranged parallel lugs on the heads of said casing, clipplates between said lugs whose inner ends project inwardly beyond the edges of the a fixed disk on its upper portion, a fan-shaft in said bearing, a reversible fan detachably mounted on the fan-shaft, a reversible faneasing having a discharge-mouth and circular openings in its opposite sides either of e which fits, is'rotatalole upon and closed by the disk on the upper part of the pillar-plate by reversing the fan-casin g side for side,rclipplates arranged on the fan-casing around the edges of the circular openings therein and extended to overlap and engage the edge of the said disk to hold the fan-casing thereupon, and bolts securing said clip-plates to the fan-casing, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.

ROBERT BURNS. Vit nesses:
