IMPROVEMENT IN FAN-BLOWERS.

vTO ALL WHOM IT MAY CONCERN:
Be it known that I, N LTIIAN PARRISII, of Kalamazoo, eount'yofKalamazoo, and State of Michigan, have invented a new and useful Improvement in Machine or Apparatus for Generating Currents of Air; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 represents a vertical section ot' my improved apparatus, taken transversely of the rock-shaft and vibrating or pendulum-fan. l
Figure 2 is a vertical section, taken in the line z z, fig. 1; and
Figure 3 is a partial section, taken in the line y y, g. 1.
Similar letters of reference denote corresponding parts in all the gures.
The object of my invention is to provide an apparatus, cheap and simple in construction, and not liable to get out of order, by means of which to generate blasts or currents of air, heated or otherwise, for purposes of ventilation, heating, or drying, or wherever artiiicial currents of air may be made available or useful; and it consists in the employment of a vibrating or pendulum-fan, working in close proximity with the stationary sides and bottom of a triangular case or box, which is provided at its sides with inlet and outlet-valves, arranged and operating as hereinafter described.
To enable others to understand and use my invention, I will proceed to describe the same with reference to the drawings, in which A represents a triangular box or oase, made of any desired dimensions to adapt it Ato the' work`it is to perform, and of any suitable material, such as tongued-andgrooved boards, or of metal united in such manner as to be rendered air-tight. The bottom, A', is made in the arc of a circle, of which the apex of the triangle, or thecentre'of the rock-shaft B, supported and vibrating thereon, is the centre, in such manner that the pendulum or fanC, secured to the rock-shaft, and vibrating therewith, shall maintain, at all points in its vibration, a fixed relation to or distance from said bottom, A. The fan C is made of a size corresponding to the width and depth of case A, so that its edges shall move in close proximity to the sides and bottom thereof, and prevent the passage of air to any considerable extent from one sideof thevfan to the other. The r'oclr shaft B is shown notched or Arecessed to the centre, where it receives the sides of the case, and is provided with set-screws or pivots b, which are so adjusted as to terminate at the centre of motion of the rock-shaft and fau, and rest upon metal plates, secured to the sides of the case in such'manner as to form a pivot or knife-edge, upon which the fan and rock-shaft vibrate, thereby avoiding the friction which'would be consequent upon the resting of the rock-shaft upon and its rotation in bearings in the case. a a are vertical partitions in ease A,
extending from the inclined sides to the curved bottom, and forming the ends of the closed portion of saidv bottom. These sides are provided with two sets of valves, le c d d1, each, the one set, c c', opening inward, and the other, eZ d1, opening outward, of case A. These valves by preference are made double,.in thernanner represented in iig. 2 being provided with a central bar or partition, e, against which the two iiap-doors, hinged on opposite sides of the opening, meet and rest when closed. Underneath the triangular case A -is arranged the air-box or receiver D, into which the air is forced from case A, and from which it is conveyed in pipes, or otherwise, to the desired point. Said receiver may be made o f any desired form or construc.tion,and extends at its ends up to a point, f, between the inlet and outlet-valves, as shown in gs. 1 and 2, 'so as to receive the air forced outward from case A through the valves d d. The bottom of the case A, between the inclined sides andthe ends of receiver D, indicated at c2 c2, is left open, or connected with suitable supply-pipes, through which the supply of air to the inlet-valves c c is received, and the receiver is perforated at any suitable point 0r points, as shown at d2, to receive discharge-pipes, through which the currents of air generated by the fan C are conveyed to the desired point. E is an upright arm or lever, connected to the roclshaft B, to the upper end of whioh'is secured a horizontal lever, F, of any suitable length, connected at one end to a pitman, G, and provided at its opposite or'short end with a counterpoise to the weight of the long arm and pitnian. The object of this arrangement of the levers and counterpoise relative to the rock-shaft and fan, is to enable them to be operated with the smallest practicable expenditure ofV power. The lower end of pitman G is designed to bevconnected to a crank, operated by a clock-mechanism, or other suitable driving-power.
The operation will be readily understood.
Motion is imparted to the rock-shaft and pendulum-fan by any-suitable mechanism, and, through the arangement of levers described, the fan is vibrated from side to side in the ease, andfltting closely therein, so that the air is prevented from passing, by it, from one side of the case to the other. The inlet-valves upon the opposite sides of the case are alternately opened and closed as the fan rocedcs from or approaches them, being open as the fan recedes, to supply air to the vacuum which would otherwise he created, and closed to prevent its escapo, thereby forcing the air, as the fan again approaches, to escape through the outlet-valves ci LZ', alternately, into the receiver D, whence it is conveyed to the desired point of use.
It will be obvious that the machine or apparatus may be made of any desired size and strength, and may be operated by any suitable power, so that the current or currents of air may be increased ordiminished, to adapt it to the purpose for which it is designed to be used.
Having now described my invention, what I claim, and desire to secure by Letters Patent, is
1. The pendulum-fan C, Yibrating, with the rock-shaft B, in close proximity with the stationary sides and bottom of the'triangular case A, in combination with the inlet and outlet-valves c and (Z, arranged and operating substantially'as and for the purpose set forth.
2. The triangular case A, provided with the inlet and outlet-valves c c cl cZ, in combination with the vibrating fan C, rock-shaft B and its operating-levers, and the air-box or receiver D, the whole constructed and arranged in the manner and for the purpose set forth.
